A update on my markdown workflow

Wed, 16 Sep 2026 00:00:00 +0000

Markdown as a presentation tool, with minor changes in your workflow.

I write almost everything in Markdown now , notes, slides, this blog. Not because it’s fashionable, but because it gets out of the way. Plain text, version-controllable, editable in any editor, and it outlives whatever app was trendy when you wrote it. The one thing that used to send me back to LaTeX or PowerPoint was producing a nicely typeset PDF or a slide deck at the end. Turns out you don’t need to leave Markdown for that either , Pandoc handles both.

Markdown to PDF

Pandoc converts a Markdown file straight into a properly typeset PDF, using LaTeX as the engine under the hood without you having to write any LaTeX yourself:

pandoc notes.md --pdf-engine=xelatex \
 -V geometry:"a4paper,margin=25mm" \
 -V mainfont="TeX Gyre Heros" \
 -o notes.pdf

A few flags worth knowing:

--pdf-engine=xelatex: lets you use system fonts (mainfont, monofont) instead of being stuck with Computer Modern.
-V geometry:...: page size and margins, same syntax as LaTeX’s geometry package.
--highlight-style=kate: nicer syntax highlighting for code blocks than the default.
-V linkcolor:blue: makes links visibly blue instead of the default boxed/black links in the PDF.

The result reads like a proper typeset document , headers, tables, code blocks, footnotes, citations if you use them , from a file you could just as easily read as plain text.

Markdown to slides

The same file (or a slightly restructured one, split by #/## headers into slides) can become a Beamer presentation:

pandoc slides.md -t beamer -V theme=metropolis -o slides.pdf

Metropolis is a clean, modern Beamer theme , no clip art, no gradients, just readable slides. This has mostly replaced Keynote/PowerPoint for me for technical talks: I outline the talk as headers and bullet points, and Pandoc does the layout.

Beamer-specific options (theme, progress bar, slide numbering) go in the YAML frontmatter of slides.md itself, so slides.md is fully self-contained and doesn’t need any flags beyond -t beamer:

---
title:
author:
date: \today
colortheme: dove
themeoptions:
- block=fill
- numbering=fraction
- progressbar=frametitle
---

# This is a sample heading for slides

Each top-level (or second-level, depending on --slide-level) header becomes a new slide, so the rest of the file is just headers and bullets under them.

The vim bindings (extra)

Since I’m always inside vim/neovim when writing Markdown, I wired both of these up as leader-key shortcuts so I never have to leave the editor or retype the command:

autocmd FileType markdown nnoremap <leader>p :!pandoc "%" --pdf-engine=xelatex -V linkcolor:blue -V geometry:"a4paper,margin=25mm" -V fontsize=10pt -V mainfont="TeX Gyre Heros" -V monofont="Latin Modern Mono" --highlight-style=kate -s -o "%:r.pdf" >/tmp/pandoc.log 2>&1 &<CR><CR>

autocmd FileType markdown map <Leader>b :!pandoc "%:p" -t beamer -V theme=metropolis -o "%:p:r.pdf" >/tmp/pandoc.log 2>&1 &<CR><CR>

<leader>p builds a PDF from the current file.
<leader>b builds Beamer slides from the current file.

Both run Pandoc in the background (trailing &), redirect output to /tmp/pandoc.log so a failed build doesn’t clutter vim, and use %:r/%:p:r to name the output PDF after the source file automatically. Only active for filetype=markdown, so it doesn’t stomp on leader mappings in other file types.

RSS Over Algorithms

Tue, 15 Sep 2026 00:00:00 +0000

TL;DR having an existential crisis because of social media feeds (again) and solving it by using RSS (not the Indian one).

I caught myself opening Instagram, closing it, and opening it again within the same minute , not looking for anything, just reaching for it out of habit. That was enough. Shorts, Reels, and the Instagram feed are overwhelming not because of the content but because of the quantity and the fact that someone else is choosing it for you. I decided to fix that. The goal is not to read everything. It is to have a feed that respects your time and attention rather than competing for it. This post is the things/tricks/tips I have figured out.

Why RSS?

I have written about RSS before and I am still a proponent of it. It is a piece of the old internet I cherish. In plain terms, it is an application that queries websites you choose to see whether they have new content. But the real reason to use it is control , no algorithm ranks your feed, no engagement metric decides what you see first, no middleman between you and the source. You subscribe to what is relevant to you, and that is it.

I use Capy Reader on mobile. It’s free, open source, and have no accounts or cloud sync – your feeds stay on your device. Capy Reader has a clean reading experience and handles YouTube feeds well.

Some feeds worth subscribing to

A few from my list that I would recommend regardless of your interests:

Quanta Magazine: long-form science journalism on math, physics, and biology. One of the few places that covers research accessibly without dumbing it down.
Finshots: Indian finance and business news in plain language. One of the better daily reads if you want to follow markets without the noise.
Project Zero: Google’s security research team publishing vulnerability deep-dives. Technical but fascinating.

Things I use RSS for.

YouTube: Every channel and playlist has an RSS feed. I follow channels like Computerphile, ColdFusion, and Two Minute Papers without ever opening YouTube. YouTube podcasts are just playlists under the hood, so they work the same way , new episodes show up in your reader like any other post. No algorithm, no autoplay, no recommendations pulling you in.
GitHub: Track releases and commits of projects you depend on. I follow SageMath commits directly , new releases land in my reader without me having to check GitHub manually.
Google Alerts: I set up alerts for specific searches , institutions, researchers, job boards like TCS Jobs. Everything lands in one place alongside my other subscriptions, filed under its own folder.
News: BBC World, The Hindu (Chennai, Kerala, Frontline), Mint, The Print, The Verge , different angles, all chosen by me. No algorithm deciding what is “relevant” today.
Blogs: Hand-picked writers I trust. Schneier on Security, Krebs on Security, Quanta Magazine, and others. The signal-to-noise ratio here is the best of all my feeds.
Reddit & Hacker News: Every subreddit has an RSS feed, and you can subscribe to just the weekly top posts (/top/.rss?t=week) instead of the live firehose. I follow r/MachineLearning, r/LocalLLaMA, r/Kerala, and a few others this way. For Hacker News, I use hnrss.org/best instead of the default feed , it filters for only the highest-voted posts, which dramatically improves quality. The official Reddit app is deliberately addictive , RSS gives you the content without the dark patterns.

How I categorize my feeds

Having a lot of feeds without structure is just recreating the problem. Here is how I organize mine:

Essential: The feeds I read every day without fail , high signal, low volume. Security blogs, math blogs, a few YouTube channels, long-form writing I genuinely look forward to. If I had to cut everything else, I would keep this folder.
Discovery: Feeds I browse when I have time. arXiv papers, ePrint cryptography papers, a few Reddit communities. For finding new ideas and rabbit holes , not daily reading, but worth checking a few times a week.
News: Global, local (Chennai, Kerala), and topic-specific sources. Kept in a separate folder so news does not bleed into everything else. I check this once a day, not constantly.
Alerts: Google Alerts for specific searches and status pages. More reactive than intentional , I glance at them when something might have happened, not as regular reading.

Other things that helped

RSS is the core, but a few smaller changes compounded it:

Podcasts over Shorts: I switched passive video time (Reels, Shorts) to podcasts. Same dead time - commute, chores, walks - but you actually finish an idea instead of half-watching fifty of them. Wrote a blog on this too see
YouTube default to Subscriptions: In YouTube settings, set the homepage to your Subscriptions feed instead of Home. Home is algorithmically curated to keep you watching. Subscriptions shows only channels you chose. One setting, massive difference.

Kudos. Hope I saved you some time.

Relationship with LaTeX Ended - Welcoming Typst

Mon, 01 Sep 2025 00:00:00 +0000

It’s been a while since my last blog, but today I bring exciting news: I’ve discovered Typst, a modern typesetting system that feels like the long-awaited alternative to LaTeX.

For years, I relied on LaTeX for academic writing, but it always felt bloated and unnecessarily complicated. Typst changes that. It solves many of LaTeX’s pain points while keeping the power and flexibility we need. In many ways, it feels like Typst could finally challenge LaTeX’s dominance in academia.

I’ve always loved the simplicity of Markdown, but when it came to equations, LaTeX was the only real option. Typst merges the best of both worlds Markdown’s ease with LaTeX’s mathematical power.

I won’t cover installation here (Google or ChatGPT will do the trick), but let me share the highlights that made me fall in love with Typst:

1. Section Headings Without the Noise

In LaTeX, defining a section is clunky:

\section{Section name}

In Typst, it’s as clean as Markdown:

= Section name

Simple and elegant.

2. Painless Equations

Typst equations look and feel familiar, but with fewer backslashes and more readability. Fractions, in particular, are much cleaner to write.

Inline equation example:

Let $a^2 + b^2 = c^2$ be the Pythagorean theorem.

Display equation example: $c = sqrt(a^2 + b^2)$

It just works.

3. Functions That Make Sense

Typst introduces functions with a syntax that is both powerful and intuitive. Unlike LaTeX, where custom commands often feel cryptic, Typst functions are straightforward, reusable, and easy to read.

#let centered-image(path, width: 60%) = {
 align(center)[
 image(path, width: width)
 ]
}

#centered-image("figures/example.png")

4. Bibliography

Citing in Typst is natural, just use @cite. References, tags, and bibliographies are built in.

Example:

This method was described in @einstein1905.

#let bib = bibliography("references.bib")
#bibliography-slide(bib)

No more BibTeX nightmares.

5. More Power for Power Users

For those who want more control, Typst provides variables, functions, and advanced layouts directly in its core. No endless packages required, everything is extendable in a clean, predictable way.

Example:

#let thesis-title = "My Awesome Thesis"
= #thesis-title

Bonus: Typstslides

If you’ve ever struggled with LaTeX Beamer, you’ll love this: Typstslides.

Final Thoughts

LaTeX has served us well, but the relationship was always complicated. With Typst, things feel refreshingly simple. For those starting their theses, writing papers, or preparing slides, I wholeheartedly recommend giving Typst a try.

Happy Typsting! 🎉

AI and Future of Art

Sun, 30 Mar 2025 00:00:00 +0000

Artificial Intelligence is rapidly transforming the art world. From AI-generated portraits to entire concept artworks, the debate over AI’s role in art is growing. The question still remains wheather AI is simply a tool that empowers artists or a distruptive force that threatens their livelihood.

One recent example is the AI replication of Studio Ghibli’s iconic art style, allowing fans to generate “Ghiblified” versions of their photos. While some fans celebrate this as a way to experience the magic of Ghibli personally, others question whether AI imitating such a unique and handcrafted style undermines the human touch that makes Ghibli special.Even Studio Ghibli’s co-founder, Hayao Miyazaki, has publicly reprimanded the use of AI in art, expressing concerns that it lacks the soul and intention that human artists bring to their work.

At the same time, it is important to recognize that AI itself is a remarkable achievement—born from human creativity, effort, and innovation. To understand the impact of AI in art, let’s compare it with past technological advancements and explore how it differs from previous innovations.

How Past Inventions Shaped Art

Throughout history, new technologies have always challenged the traditional ways of creating art. Here are some key examples:

Photography vs. Painting (19th Century): When photography emerged, many painters feared it would make their craft obsolete. Instead, it pushed painters toward new styles like Impressionism and Abstract Art, emphasizing emotion and creativity over realism.
Digital Art vs. Traditional Hand-Drawn Art (20th Century): Early digital tools like Photoshop and graphic tablets faced criticism for “devaluing” traditional art. However, they became essential in fields like animation, game design, and illustration. Today, digital art is widely respected.
The Printing Press & Handmade Books (15th Century): The printing press threatened scribes who manually copied books, but it made literature more accessible. Similarly, AI-generated art could make artistic tools available to more people, democratizing creativity.
The Industrial Revolution & Craftsmanship: Machines replaced many hand-crafted processes, but handcrafted art and goods remained valuable for their uniqueness. AI-generated art may push human-made works to be seen as more exclusive and valuable.

How AI Art differs from past inventions

All the inventions listed above required direct human input in one way or ather, but, AI is completely autonomus. When Photography was indroduced it created the need for photographers. Furthermore even when the invention of camera further got democratized to the point mostly everyone have them in their pockets, we still need talented photographers. But, this might not be the case for AI art. This scale in which AI can be used can disrupt the current economics of the art industry.

One of the major limitations of AI-generated art is its lack of originality. AI can only learn from past patterns and lacks the personal touch and lived experience that human artists bring to their work. While AI can generate stunning visuals, it cannot convey deep emotions or unique artistic visions in the same way a human can. However, AI can function as a tool for artists and enrich the way they create art. Picture a single person creating a movie entirely on their own, fully expressing themselves without the constraints of money. This new world of creative empowerment is also something we should strive for.

At the same time, AI tools can reduce the workload for illustrators. Tasks that once took hours can now be completed in minutes, allowing artists to focus on refining their creative vision rather than getting bogged down in repetitive processes. Features like an “undo” button, which would have been unthinkable in traditional painting, are now standard in digital art software. AI represents yet another leap forward in creative technology, making artistic tools more powerful than ever before.

The Hard Work Behind AI Art

AI-generated art may seem like an effortless process, but in reality, developing these systems requires immense labor and innovation. Training AI to create art is not simple—it involves complex algorithms, vast datasets, and meticulous refinement. One of the biggest hurdles AI developers have faced is teaching AI to replicate intricate artistic styles. Early AI models struggled with fundamental details such as generating human hands correctly, often producing extra fingers or distorted anatomy. Likewise, text rendering within AI-generated images was notoriously difficult, frequently resulting in unreadable or misspelled words.

Recent advancements, however, have made AI significantly more precise. The latest ChatGPT model, for example, excels at maintaining coherence, handling intricate details, and preserving logical consistency across long-form text. This level of accuracy, which once seemed impossible, showcases just how much work goes into refining AI models. The same effort applies to AI art—achieving smooth brush strokes, dynamic lighting, and stylistic nuances is no trivial task. What we see today is the product of years of research and iteration, making AI-generated art an impressive technological achievement.

Conclusion

While AI has the potential to revolutionize art, it also raises important ethical and creative questions. History shows that technology does not erase art—it transforms it. However, AI is unique in that it can create without human experience or emotion. Perhaps the best path forward is responsible AI use—where AI is seen as a creative assistant rather than a creative replacement. Ethical guidelines, fair compensation for artists whose work is used in AI training, and the continued celebration of human-made art will be crucial in shaping the future of AI in the art world.

As for beloved styles like Studio Ghibli’s, AI may allow fans to engage with them in new ways, but it can never replicate the magic that comes from the skilled hands and artistic vision of its original creators. Hayao Miyazaki himself has criticized AI-generated art, emphasizing that true art is about human emotion, effort, and storytelling rather than mere replication of style.

At the same time, we should not forget that the AI technology itself is a product of human creativity, research, and dedication. It is a symbol of our capacity for invention and problem-solving, much like the artistic masterpieces it now seeks to emulate.

Navigating Misinformation: A Digital Survival Guide

Fri, 03 Nov 2023 00:00:00 +0000

In today’s digital age, we find ourselves in a constant battle against the relentless waves of misinformation. The information landscape has evolved significantly over the years, and with the advent of social media and advanced technologies, the challenges have grown exponentially. To stay afloat and make informed decisions, we need a digital survival guide. The story of news media and propaganda has a long history, but it has reached new heights in the digital era. Misinformation, or false and misleading information, is disseminated at an unprecedented scale, thanks to social media. The information landscape is in a constant state of flux, and this discussion has never been more pertinent than in today’s global context.

In this blog, we’ll explore the world of misinformation, its prevalence on social media, personalized searches, and the role of AI models like GPTs.

Social media platforms have become breeding grounds for misinformation. The degree of misinformation varies from platform to platform, and the emergence of AI tools like deepfakes has made the situation even worse. False information is often spread using manipulated images, videos, and even content from video games or movies.

How to counter: To combat this issue, it’s essential to be selective about the platforms you use. Choose platforms that have measures in place to counter misinformation, and always verify information from multiple sources before accepting it as truth.

Personalized Searches

Search engines like Google have revolutionized the way we access information. They cater search results based on your location and preferences. However, the drawback is that these results can sometimes create a filter bubble, limiting your exposure to diverse viewpoints and information.

How to counter: To break free from this filter bubble, consider using alternative search engines like DuckDuckGo. These platforms prioritize user privacy and neutrality, providing a broader spectrum of search results.

GPTs: The New Search Engine

We can envision a future where traditional search engines like Google might be replaced by AI models like GPT. These models offer the convenience of conversational interaction, but they come with their own set of challenges. GPTs are trained on vast amounts of existing text data, which can perpetuate biases in their responses.

How to counter: While AI models like GPT are valuable for factual information, exercise caution when seeking opinions and viewpoints. Always cross-check with multiple sources to ensure a well-rounded perspective.

Key Takeaways

In a world deep with misinformation, it’s crucial to equip yourself with the right tools and strategies to navigate the digital sea. Here are some key takeaways:

Diversify your information sources and don’t rely solely on social media for news.
Verify information from multiple reputable sources.
Consider using alternative search engines like DuckDuckGo to escape filter bubbles.
Use AI models like GPT for factual information but be cautious when seeking opinions.
Consider using RSS readers for getting news derectly from the source.

By following these guidelines, you can navigate the digital landscape more effectively, making informed decisions in an age of misinformation.

The Intersection of Atheism, Science, and Belief: Reflections Inspired by `Kushi`

Mon, 02 Oct 2023 00:00:00 +0000

I recently watched the Telugu romantic comedy film “Kushi” (2023), and its portrayal of atheists sparked some intriguing thoughts that I felt compelled to share. In the movie, the character representing an atheist is depicted as a “science believer,” which, from my perspective, falls short of capturing the essence of atheism. Allow me to elaborate on this matter further. There’s a distinction between what we can call a “strong atheist” and a “science supporter.” A strong atheist, based on the classification by renowned evolutionary biologist Richard Dawkins, is a person who asserts with 100% certainty that there is no God. However, even in this extreme case of atheism, one should not automatically assume a strong inclination toward science. The reason I emphasize the distinction between a “supporter of science” and a “believer” is rooted in the core tenets of scientific thinking. Science is fundamentally about inquiry, skepticism, and the pursuit of knowledge based on empirical evidence. It is not a system of belief but a conceptual tool for understanding the world. In science, one cannot merely believe; one must question in order to comprehend.

It’s essential to recognize that science is not a religion; it is a methodological approach to gaining insights into the natural world. I can understand why some may associate atheism with science, as atheists often use scientific principles to understand or teach about how things work. However, it’s crucial to differentiate between the two concepts. The assumption of the existence of God is, in a way, a scientific statement. It posits the existence of a supernatural being within the framework of the natural world. However, the reason many theists shy away from using science to prove the existence of God is that such endeavors have historically proven futile. Science, by its very nature, requires testable hypotheses and empirical evidence, and these have been elusive when it comes to matters of faith.

My own stance in this ongoing discourse aligns with what can be termed a “De facto atheist.” Based on the current evidence available to me, I find the existence of God to be highly improbable, and I live my life on the assumption that there is no God. However, what keeps me from adopting the position of a strong atheist is the recognition that doing so would involve assuming the conclusion before conducting the experiment, an approach that goes against the principles of scientific inquiry. Moreover, it’s crucial to emphasize that being a science supporter means being open to various opinions and respecting the diversity of thought. Healthy debates should be encouraged, and differing perspectives should be acknowledged and examined. This brings me to a critical point: I strongly disagree with the approach taken by the “atheist” husband in the movie “Kushi,” where he attempts to impose his beliefs on his family. In societies where culture and religion intersect significantly, it’s essential to strike a balance. While we can’t ignore the cultural context, we should always encourage critical thinking and skepticism.

In conclusion, “Kushi” may have prompted me to reflect on the portrayal of atheists, but it has also reminded me of the intricate interplay between atheism, science, and belief. It’s fascinating how a mediocre film can serve as a catalyst for discussions on profound topics, encouraging us to ponder the complexities of our own beliefs and the role of science in our understanding of the world. The key takeaway is that, regardless of our beliefs, we should always remain open to new ideas, respect diverse opinions, and promote constructive dialogue within our communities.

Exploring GIFs: An Animated Journey

Tue, 26 Sep 2023 00:00:00 +0000

If you’re a regular visitor to the digital landscape, you’ve likely stumbled upon a timeless question: Is it pronounced “JIFF” or “GHIF”? Interestingly, both pronunciations are deemed acceptable, despite the official stance of the GIF format’s creator, Steve Wilhite, who advocated for the soft “G.” But beyond this linguistic debate lies a rich world of GIFs that has captivated internet users since their inception.

What is a GIF?

The Graphics Interchange Format, better known as GIF, is a bitmap image format developed by a team at the online services provider CompuServe, under the leadership of American computer scientist Steve Wilhite. It made its debut on June 15, 1987. The widespread usage of GIFs on the World Wide Web can be attributed to their broad support and compatibility across various applications and operating systems.

One of the standout features of GIFs is their ability to support up to 8 bits per pixel for each image, enabling a single image to reference its own palette of up to 256 different colors selected from the 24-bit RGB color space. GIFs gained popularity due to their use of the Lempel–Ziv–Welch data compression method, which proved more efficient than previously employed techniques. In September 1995, Netscape Navigator 2.0 introduced the ability for animated GIFs to loop, adding a new dimension to their appeal.

Despite being developed by CompuServe, GIFs used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm, which had been patented by Unisys in 1985. This led to controversy over licensing agreements between Unisys and CompuServe in 1994, ultimately prompting the development of the Portable Network Graphics (PNG) standard. However, by 2004, all patents related to the proprietary compression used in GIFs had expired.

The Meme, The Legend

In May 2015, Facebook embraced the GIF trend by adding support for these animated images. In January 2018, Instagram followed suit, introducing GIF stickers to its story mode. GIFs have become an integral part of pop culture, finding their way into virtually every chat service. They offer a unique form of expression that goes beyond words and even emoticons.

GIFs let you showcase your pop culture knowledge with quirky references, and they allow you to be a bit of a show-off in the best possible way. They can convey humor, reactions, and emotions like no other medium, making them a staple in internet communication.

Burn All GIFs?

While GIFs have undoubtedly left their mark on the digital landscape, they are not without their drawbacks. As an older format, they are less optimized compared to current standards. Storing and managing a plethora of GIFs can be a logistical nightmare due to their large file sizes and limited color palettes.

The rise of more efficient and versatile formats has led some to question the long-term viability of GIFs in the digital ecosystem. Nevertheless, their enduring popularity and unique charm ensure that they won’t disappear from the internet anytime soon.

Conclusion

In the world of GIFs, the debate over pronunciation is just the tip of the iceberg. These animated images, born in the late ’80s, have evolved into a dynamic form of expression, a cornerstone of internet culture, and a source of endless entertainment. Whether you’re a “JIFF” or “GHIF” advocate, there’s no denying the enduring and enchanting allure of GIFs in our digital playground. So, as you stroll through the vast expanse of the internet, don’t be surprised if you encounter a GIF that makes you smile, laugh, or even ponder the intricacies of pronunciation.

When Mistakes Make Masterpieces: The Unintended Innovations in Technology

Sat, 23 Sep 2023 00:00:00 +0000

In the ever-evolving landscape of technology and innovation, the unexpected often leads to the extraordinary. Some of the most cherished features we enjoy today were born not from meticulous planning but rather from bugs, glitches, and unintended twists of fate. In this blog post, I will delve into the realms of technology, gaming, and creative design to uncover instances where mistakes turned into masterpieces.

1. UNIX Hidden Files

Dennis Ritchie and Ken Thompson’s decision to exclude ‘.’ and ‘..’ in the ’ls’ command in Unix was an accidental creation. By looking at just the first character of filenames, they unintentionally ushered in the era of hidden files in the Unix system. This is feature is still adorned by many as they are quite uselful in storing configuration files.

2. Gmail’s Second Chance

From the linux world, let’s pivot to emails, where Gmail’s “Undo Send” feature was accidentally discovered. Initially an experiment, it emerged from a bug report and now saves countless inboxes from premature email dispatch. I cannot simply count the number of times this has saved me.

3. Vi’s Quirky ‘c’ and ‘w’

In text editing, Vi introduced us to the curious behavior of ‘c’ and ‘w.’ Despite being different from what the creator Bram Moolenaar initially intended, this behavior has persisted, captivating users and becoming part of Vi’s unique charm.

4. “Ctrl+Alt+Delete” for Windows Login

The famous “Ctrl+Alt+Delete” combination to access the Windows Task Manager was originally a debugging feature in early versions of Windows meant for the developers. It was never intented for the three-finger salute to become so familiar to end users.

5. Deep Blue vs. Kasparov

In chess, where the infamous match between Deep Blue and Garry Kasparov unfolded. A bug in Deep Blue’s programming led to a surprising move, adding intrigue and legend to the world of chess.

6. Grand Theft Auto’s Criminal Evolution

From chess, we shift gears to gaming with Grand Theft Auto (GTA). Initially conceived as a cops and robbers game, a bug turned the tables, making the cops relentless pursuers. This twist became the core feature of GTA’s thrilling gameplay.

7. Super Mario 64’s Backwards Long Jump

Super Mario 64 players discovered a glitch called the “Backwards Long Jump,” allowing them to bypass obstacles. Speedrunners embraced this bug, turning it into a celebrated technique.

8. The Accidental Creeper

Our quest leads us to the realm of video games, where Minecraft’s “Creeper” enemy type emerged from a mistake. Markus Persson, or Notch, accidentally reversed dimensions while creating a Pig creature, resulting in the iconic green menace known for explosions and charm.

Conclusion

These instances of mistakes turning into masterpieces highlight the creative and adaptive nature of human ingenuity. They serve as a reminder that innovation often arises from adaptation and a willingness to embrace unexpected outcomes. So, the next time you encounter a bug or a glitch, remember that it might just be the birth of something extraordinary.

Ode to the terminal

Mon, 11 Sep 2023 00:00:00 +0000

To my usual readers, if there are any out there, I’d like to ask for a bit of space because I’m about to go on a poetic rant.

In tech’s vast world, I’ll take some space,
To share my thoughts and make my case.
In praise of something pure and true,
The terminal’s charm, I’ll give my due.

In the world of tech, simplicity we find,
Within the terminal, a connection so fine.
Why seek mediators, distant they stand,
When we can speak closely, hand in hand.

Why carry the weight of unnecessary freight,
When we can travel light, appreciate?
I’d choose you, my love, again and again,
Even if it meant joining the cult of 6, my friend.

In this digital sea, vast and true,
The only seashell I desire is you.
In this ocean of options so grand,
The one I desire, you understand.

Growing Code: Lessons from the Garden and 'The Pragmatic Programmer'

Sat, 02 Sep 2023 00:00:00 +0000

In the digital world, we often hear about programming being compared to craftsmanship or engineering. While these comparisons are certainly valid, there’s another analogy that beautifully captures the essence of coding: coding as gardening. The idea was inspired by the timeless wisdom found in “The Pragmatic Programmer” book written by Andrew Hunt and David Thomas, which highlights the parallels between nurturing a garden and nurturing your codebase.

Planting Seeds

Every software project begins with a single line of code, just as a garden starts with planting seeds or seedlings. These initial lines of code are like the seeds that will eventually sprout into a full-fledged program. Just as a gardener carefully selects the right soil, location, and conditions for their plants, a developer must make decisions about programming languages, frameworks, and architecture to ensure a solid foundation.

Nurturing Growth

A garden requires ongoing care to flourish, and so does your code. Regular updates, bug fixes, and improvements are essential for maintaining a healthy software project. Think of these updates as the equivalent of providing water, sunlight, and nutrients to your plants. Neglecting your codebase can lead to stagnation and eventual decay called software rot.

Much like a gardener who prunes overgrown branches to encourage healthy growth, a programmer may refactor code to remove redundancies and improve readability. This pruning process ensures that your code remains manageable and continues to thrive.

Rearranging the Plants

Just as a gardener might rearrange plants to create a visually appealing landscape, programmer often need to refactor and reorganize code to improve its overall aesthetics and maintainability. This involves tasks like renaming variables for clarity, reordering functions for better readability, and restructuring code for a more logical flow.

Embracing Seasons

Gardens go through seasons, each with its unique challenges and opportunities. Similarly, software projects evolve. New requirements, technologies, and user feedback shape the direction of your code. Embrace these changes, just as a gardener adapts to the changing weather and seasons, to keep your project relevant and aligned with its goals.

Harvesting the Fruits

The ultimate goal of a garden is to harvest the fruits of your labor. In the world of programming, this is akin to your code working as you have envisioned it. Just as a gardener takes pride in the bountiful harvest, a programmer feel a sense of accomplishment when their program serves its purpose effectively.

Conclusion

So, the next time you sit down to code, consider yourself not just a programmer but a gardener of digital landscapes, nurturing your codebase and watching it flourish over time.

Happy programming, and happy gardening! 🌱👩‍💻🌻

Mastering Gmail: Unveiling the Infinite Gmail Glitch

Thu, 03 Aug 2023 00:00:00 +0000

In today’s digital age, email has become an indispensable part of our lives. Among the various email service providers, Gmail stands out as one of the most popular platforms. Many users are unaware of a powerful set of features that Gmail offers, which can be collectively referred to as the “Infinite Gmail Glitch.” In this blog, we will delve into the two main methods that unlock a world of possibilities with your Gmail account. Let’s explore how you can create an infinite number of Gmail addresses and make email management a breeze!

Method 1: The Plus Sign Trick

The first trick involves using the plus sign in your Gmail address. Most people are not aware that Gmail ignores anything after the plus sign, considering the email address to be the part before it. For instance, if your Gmail ID is yourname@gmail.com, then all the following addresses will also belong to you:

yourname+facebook@gmail.com
yourname+amazon@gmail.com
yourname+RANDOM@gmail.com

This method offers an array of benefits. One of the most useful applications is automatic filtering and labeling of emails. By using these variations when signing up on different websites or services, you can easily create filters and labels to organize your incoming emails systematically.

Method 2: The Dot and Case Ignorance

Gmail is particularly lenient when it comes to dots (periods) and case variations in your email address. Essentially, Gmail disregards any dots and treats upper and lower case letters as the same. For example, if your email address is yourname@gmail.com, then YoUr.NaMe@gmail.com is also your email address.

With this method, you can effortlessly generate email aliases without creating new accounts. It’s an ideal way to keep track of which websites or services are sharing your email address and can be a useful tool in managing your online presence.

Use Cases:

Streamlined Email Organization: By using the plus sign trick, you can have specific variations for each website or service you sign up for. Then, set up filters and labels to automatically categorize incoming emails, making it easier to identify their source and purpose. You can learn more about creating advanced filters here
Sign-ups: You can use different aliases to sign up for newsletters, subscriptions, or online forms without disclosing your primary email address. This helps in reducing spam and clutter in your primary inbox.
Quick Identification of Email Sources: By creating aliases based on the context, you can immediately recognize which websites or contacts are sending you emails. This can be particularly helpful in professional and personal settings.
A Dump Address: Create a specific Gmail alias like yourname+spam@gmail.com and use it when you’re unsure whether the service you are signing up for will send you spam.

Conclusion:

With the Infinite Gmail Glitch, you can take full advantage of Gmail’s powerful features to manage your emails with ease and efficiency. The plus sign trick and dot/case insensitivity are valuable tools for creating aliases, automating email organization, and maintaining a clean inbox. So, embrace these hacks and unlock the true potential of your Gmail account! Happy emailing!

Mastering LaTeX: Three Tips for Efficient Typesetting

Mon, 31 Jul 2023 00:00:00 +0000

LaTeX is a powerful typesetting tool widely used in academic and scientific fields for creating professional documents. If you’re new to LaTeX, don’t worry! In this blog, we’ll explore three essential tips to help you make the most of LaTeX and elevate your document preparation skills. Let’s dive in!

Uno: Create a Preamble Template

The preamble in a LaTeX document is the section before \begin{document} that contains important settings and customizations. A smart way to streamline your work is by creating a preamble template tailored to different types of documents, such as slides, articles, and books. By doing so, you save time and ensure consistency across your LaTeX projects. To utilize these templates, you can simply call them using the \input{preamble} command in your main document.

For example, you can create preamble.tex, and then in your main document file (e.g., article.tex), you would use:

\documentclass{article}

% Load the preamble from the separate file
\input{preamble}

\begin{document}
% Your content goes here
\end{document}

Dos: Define Custom Commands

LaTeX allows you to define custom commands, making it a breeze to create shortcuts for frequently used symbols or complex expressions. Instead of writing lengthy equations repeatedly, you can use the \newcommand and \renewcommand macros to create your own custom shortcuts. It’s a good practice to use \ensuremath within the command definitions to allow seamless usage both in and outside of math mode. With this technique, you can skip wrapping symbols with $...$ or $...$ each time you need them.

If you’re uncertain whether a command already exists, you can use \providecommand, which creates the command only if it doesn’t already exist. Also, consider using semantic names for your custom commands. For example, instead of \x, consider a more descriptive name like \variableX , so it’s easier to understand the purpose of the command when reviewing your document later.

Here are some examples of custom commands:

\newcommand\varx{\ensuremath{\mathpzc{x}}}
\newcommand\NN{\ensuremath{\mathbb{N}}}
\renewcommand\O{\ensuremath{\emptyset}}
\newcommand\QQ{\ensuremath{\mathbb{Q}}}
\newcommand\CC{\ensuremath{\mathbb{C}}}
\newcommand\FF{\ensuremath{\mathbb{F}}}
\newcommand{\m}{\ensuremath{\mathfrak{m}}}
\renewcommand{\S}{\ensuremath{\mathcal{S}}}

Tres: Find Your Favorite Editor

One of the great things about LaTeX is its compatibility with various text editors. Finding an editor that suits your preferences and workflow can significantly enhance your LaTeX experience. Some popular LaTeX editors include:

TeXstudio: An open-source cross-platform LaTeX editor with an integrated PDF viewer and advanced editing features.
Visual Studio Code with LaTeX Workshop: If you prefer a versatile code editor, VS Code with the LaTeX Workshop extension is a popular choice with its extensive features and customizable options.
Emacs with AUCTeX: Emacs is a powerful text editor with AUCTeX, providing a comprehensive LaTeX editing environment for seasoned Emacs users.
Vim with Vimtex: For users who love the efficiency of Vim, Vimtex is a fantastic plugin that brings powerful LaTeX editing capabilities to Vim. With features like automatic compilation, integrated PDF viewing, and advanced syntax highlighting, Vimtex offers a seamless LaTeX editing experience within the Vim text editor.
TeXShop (macOS): A user-friendly LaTeX editor for macOS users with built-in tools for typesetting and previewing documents.
Overleaf: A web-based collaborative LaTeX editor that allows real-time collaboration and access to a vast library of templates.

Experiment with different editors to find the one that suits your needs best. Each editor offers unique features, plugins, and customization options that can make your LaTeX workflow more efficient and enjoyable.

Bonus:

Detexify is a valuable online tool that comes to the rescue when you can’t remember the exact LaTeX command for a particular symbol. It allows you to draw the symbol on its website, and in return, Detexify provides you with the corresponding LaTeX command. This comes in handy when you encounter uncommon symbols or need a quick reference for the LaTeX notation. Embrace Detexify as your LaTeX symbol-finding companion!

Conclusion:

Mastering LaTeX is all about optimizing your workflow and leveraging the capabilities it offers. Embrace these tips, practice regularly, and soon you’ll be a LaTeX pro! Happy typesetting!

Typography Tales: The Curious case of lorem ipsum!

Thu, 20 Jul 2023 00:00:00 +0000

Have you ever wondered about the cryptic text that designers and publishers use as a placeholder in their work? This mysterious text, known as “Lorem ipsum,” has a fascinating history that dates back centuries. Join me on a journey as we delve into the world of Lorem ipsum, uncovering its true origins and understanding why it continues to be an essential part of the design process. Additionally, we’ll explore some compelling alternatives to Lorem ipsum that designers can consider for their projects.

Lorem ipsum: The Meaning and Origins:

As we explore the enigmatic roots of Lorem ipsum, we find that it is derived from the Latin philosophical work “De finibus bonorum et malorum” written by Cicero, a renowned Roman philosopher from ancient times. However, the Lorem ipsum we know today is a corrupted version, with some words omitted and nonsensical additions. Ironically, the first two words, “Lorem ipsum,” can be traced back to the phrase “dolorem ipsum,” meaning “pain itself” in Latin.

The Purpose Behind its Usage:

The use of Lorem ipsum as a placeholder text is not merely a random choice. In the world of publishing and graphic design, creating layouts before the actual content is available is a common practice. However, using random text would fail to mimic the natural flow of language and might misrepresent the design’s final appearance. The familiarity and structure of Lorem ipsum enable designers to maintain the intended aesthetics and readability during the design phase.

A Digital Revolution: Lorem Ipsum in the Modern Age:

Although Lorem ipsum has been employed in typesetting since the 1960s, its digital journey began in the mid-1980s. Aldus, the pioneering company behind the popular desktop publishing program PageMaker, introduced Lorem ipsum to the digital world. Over time, many other word processors, including Pages and Microsoft Word, have embraced this quirky placeholder text, making it a ubiquitous part of the design process.

The Unique Properties of Lorem Ipsum:

While Lorem ipsum has become a standard choice for designers, it is not the only placeholder text option available. Its properties are not entirely unique, allowing for alternative replacements. In this section, we’ll explore some compelling alternatives to Lorem ipsum, such as:

Bacon Ipsum: A mouthwatering alternative that generates text with a focus on various types of bacon.
Cupcake Ipsum: A sweet and delightful option that fills your layout with cupcake-themed text.
Hipster Ipsum: For a touch of hipster flair, this alternative generates text with a trendy and artistic vibe.
Pirate Ipsum: Arrr! This fun alternative injects your design with some swashbuckling pirate-themed text.
Zombie Ipsum: A spooktacular option that fills your layout with zombie-inspired gibberish.

While Lorem ipsum continues to be a popular choice, designers now have exciting alternatives to explore, allowing them to inject creativity and uniqueness into their projects.

Mastering SSH: Tips and Tricks for Efficient Remote Connections

Sat, 15 Jul 2023 00:00:00 +0000

SSH (Secure Shell) is a powerful tool for establishing secure remote connections and executing commands on remote computers. In this blog post, we will explore some essential tips and tricks to enhance your SSH experience and make your remote connections more efficient and secure.

Tip 1: Use SSH Keys! Not Passwords!

One of the best practices in SSH is to use SSH keys instead of passwords for authentication. SSH keys provide stronger security and eliminate the need to remember and enter passwords each time you connect to a remote server. Additionally, you can further enhance security by disabling password authentication altogether.

To generate an SSH key pair, open a terminal and run the following command:

ssh-keygen -f ~/.ssh/<filename> -t ed25519 -a 100

Replace <filename> with the desired name for your key pair. This command generates an Ed25519 key with a key derivation function (KDF) cost factor of 100.

Instead of Ed25519 we can use -t rsa -b 2048, it uses RSA (Rivest-Shamir-Adleman) is an older algorithm that has been widely used for decades and is considered secure when using a sufficiently large key size, such as 2048 bits or higher. Ed25519, on the other hand, is a relatively new algorithm based on elliptic curve cryptography (ECC) and is designed to be more efficient and secure with a shorter key lengths.

Tip 2: Copy SSH Public Key to Remote Server

After generating your SSH key pair, you need to copy the public key to the remote server to enable passwordless authentication. Use the following command:

ssh-copy-id -i ~/.ssh/<filename>.pub user@domain

Replace <filename> with the actual name of your key pair and provide the appropriate username and domain for the remote server. This command securely transfers the public key and adds it to the authorized_keys file on the remote server.

Tip 3: Utilize ssh-agent for Key Management

If you encounter issues while connecting to the remote server even after setting up SSH keys, it might be due to the key not being added to the ssh-agent. The ssh-agent is a program that holds private keys in memory, allowing you to use them without entering a passphrase repeatedly.

To add your private key to the ssh-agent, use the following command:

ssh-add ~/.ssh/<filename>

Replace <filename> with the actual name of your private key. This command adds the private key to the ssh-agent, and you can use the -A option to forward the same keys to the remote host upon login.

Tip 4: Simplify SSH Connections with the Config File

Manually specifying connection details for each SSH session can become cumbersome. To simplify the process, you can use the SSH config file to define host-specific configurations.

Open the SSH config file located at ~/.ssh/config and add the following configuration:

Host RemoteHost
	HostName <ip-address>
	IdentityFile ~/.ssh/<filename>
	User <username>

Replace <ip-address> with the IP address or domain name of the remote host, <filename> with the actual name of your private key, and <username> with the username on the remote server.

By defining these configurations, you can establish an SSH connection to the remote host simply by running ssh RemoteHost.

Tip 5: Disable Password Authentication

After setting up your SSH key pair, it’s essential to disable password authentication to enforce key-based authentication. Follow these steps to disable password authentication:

Open the SSH server configuration file on the remote server. The file is usually located at /etc/ssh/sshd_config.
Look for the line that specifies PasswordAuthentication and change its value to no.
Save the changes and exit the editor.
Restart the SSH service on the remote server for the changes to take effect.

With password authentication disabled, you can now connect to the remote server using only your SSH key, providing an extra layer of security for your SSH connections.

Remember to keep your private key secure and use a strong passphrase when generating the key pair. Additionally, ensure that you have a backup of your private key to avoid any potential data loss.

Bonus Tip: Boost Productivity with Tmux

Tmux is a terminal multiplexer that allows you to manage multiple terminal sessions within a single SSH connection. It enables you to split the terminal window, create multiple panes, and switch between them effortlessly.

To install Tmux, use the appropriate package manager for your operating system. Once installed, you can start a new Tmux session by running tmux in your SSH terminal. Refer to the earlier section in this blog for essential Tmux commands.

Embracing Freedom: Git vs GitHub in the Microsoft Era

Fri, 07 Jul 2023 00:00:00 +0000

In the world of software development, Git and GitHub are two popular tools that often go hand in hand. However, it’s essential to understand their distinctions and how they serve different purposes in the development workflow. This blog post aims to clarify the differences between Git and GitHub, their unique functionalities, and the scenarios in which each tool shines.

Git: The stupid content tracker

Git, a distributed version control system, has revolutionized the way software development teams collaborate and manage source code.

Git development commenced in April 2005 when Linus Torvalds, known for creating Linux, decided to create a new source-control management (SCM) system. Interestingly, Torvalds playfully explained that he named it “git” after himself, as he tends to name his projects in such a manner. The term “git” has multiple meanings depending on one’s interpretation:

A random, pronounceable three-letter combination that does not conflict with any existing UNIX command. It could be considered a mispronunciation of “get,” although the relevance of this is debatable.
Descriptive adjectives like “stupid,” “contemptible,” “despicable,” and “simple” from the dictionary of slang. One can choose the interpretation that suits their mood.
In a positive light, “git” stands for “Global Information Tracker.” This definition implies that everything is working smoothly, bringing joy and illumination to the user.
On the other hand, in moments of frustration, “git” may stand for “Goddamn Idiotic Truckload of Sh*t” when encountering issues or failures.

The source code itself humorously refers to Git as “the information manager from hell.” The motivation behind creating Git arose when the free license for the proprietary SCM, BitKeeper, was revoked for Linux kernel development in 2002. This incident prompted Torvalds to develop a new, efficient, and open-source SCM system, which eventually became Git.

Github: Join the Microsoft Empire, One Commit at a Time.

GitHub is a web-based hosting service for Git repositories. It provides a platform for collaboration, version control, and code management.

Although GitHub is a widely used platform for hosting Git repositories, it’s important to remember that GitHub is not Git itself. Git is a distributed version control system that can be hosted independently. If you prefer to have complete control over your repositories, you have the option to host your own Git service. You can find guidance on setting up your own server by referring to the link here.

Furthermore, there are alternative hosting platforms available, such as Bitbucket and GitLab, which offer similar functionalities to GitHub. These alternatives provide additional choices for hosting and collaborating on Git repositories.

Another option to explore is USB-based hosting, providing a portable solution for managing your Git repositories. This approach is particularly useful for carrying code changes between different computers. However, it’s important to be aware of a significant drawback: relying solely on a USB drive for hosting repositories puts your code and data at risk. If the USB drive is lost or misplaced, you could potentially lose your valuable work. While USB-based hosting may not be ideal for collaborative work, it serves as a convenient method for transferring code changes across machines.

Conclusion

Ultimately, the decision between Git, GitHub, or alternative hosting solutions depends on factors like collaboration requirements, customization needs, and individual preferences.

Remember, in the vast world of version control and code collaboration, the power lies in your hands. Choose the solution that best aligns with your values, goals, and vision for your projects, regardless of the corporate forces at play. Stay independent, stay innovative, and keep pushing the boundaries with your code.

Exploring Fediverse: An Alternative to Centralized Social Media

Thu, 06 Jul 2023 00:00:00 +0000

The Fediverse is an innovative approach to web publishing that challenges the traditional model of centralized social media platforms. Instead of relying on a single organization to govern the entire network, the Fediverse consists of a collection of interconnected servers called instances. These instances enable users to create identities and communicate across instance boundaries, promoting decentralization, freedom of expression, and resistance to censorship.

Key Features of the Fediverse:

Decentralization: The absence of a central authority in the Fediverse ensures that no single entity has complete control over the network. This decentralized structure prevents censorship and regulation from being imposed uniformly across all instances.
Freedom of Choice: Users in the Fediverse have the freedom to choose the content they wish to engage with. By selectively linking with instances that align with their values and regulations, users can curate their online experience based on their preferences.

Ostatus Protocol and Mastodon:

The Ostatus protocol, introduced in 2008, is a notable example of a federated microblogging protocol used within the Fediverse. Platforms like Mastodon and GNU Social have adopted this protocol to create decentralized social media experiences. Mastodon, in particular, has gained popularity due to its similarities to Twitter, attracting users seeking an alternative to centralized platforms.

Mastodon offers the ability to host self-owned instances, ensuring that no single individual or organization can monopolize the narrative on the platform. This feature empowers users and promotes a diverse range of voices and perspectives.

The Ambiguous Thread Narrative:

Thread, a new product from Meta (formerly Facebook), claims to be a part of the Fediverse but lacks transparency regarding instance creation and overall policies. Without clarity on these crucial aspects, it is uncertain how Thread will employ regulations and ensure user freedoms. While this development may introduce more people to the concept of the Fediverse and open-source social networks, there are concerns about potential mismanagement or a departure from the core principles of openness and decentralization.

Pixelfed: Pixelfed is a federated image-sharing platform inspired by Instagram. It focuses on privacy and decentralization, allowing users to self-host their instances and share photos with others in the Fediverse.
PeerTube: PeerTube is a decentralized video hosting platform that enables users to host and share videos in a federated manner. It offers an alternative to centralized video platforms like YouTube, allowing users to control their content and participate in a broader network of instances.
WriteFreely: WriteFreely is a federated blogging platform that promotes decentralized publishing and individual ownership of content. It allows users to create self-hosted blogs and interact with other bloggers across instances.
Funkwhale: Funkwhale is a federated music sharing platform that focuses on promoting independent artists and decentralized music streaming. It allows users to create their music libraries, playlists, and share music with others in the Fediverse.
Misskey: Misskey is a decentralized social media platform that emphasizes user privacy and control. It offers features such as customizable timelines, self-hosting options, and robust moderation tools.

These alternatives within the Fediverse offer diverse social media experiences while upholding principles of decentralization, user autonomy, and resistance to censorship. Exploring these platforms can help individuals find the one that aligns with their values and preferences.

Conclusion:

The Fediverse presents a compelling alternative to centralized social media platforms. By leveraging interconnected instances and prioritizing user autonomy, the Fediverse encourages freedom of expression, resists censorship, and allows individuals to shape their online experiences. Platforms like Mastodon have demonstrated the feasibility and appeal of decentralized social networking, while the emergence of Thread raises questions about how a centralized entity will navigate the principles and benefits of the Fediverse. As the landscape of online social interaction continues to evolve, exploring decentralized alternatives can empower users and foster a more open and inclusive digital ecosystem.

Exploring the World of Torrents: Why Choose Torrenting?

Fri, 16 Jun 2023 00:00:00 +0000

In a world dominated by centralized servers, torrents stand as a unique and alternative method of file sharing. Unlike traditional server-based downloads, torrents rely on distributed sharing, allowing users to simultaneously download and host (seed) content. This decentralized approach offers numerous advantages, particularly in terms of scalability and resilience. In this blog post, we’ll delve into the world of torrents, explore their benefits, and learn how to utilize this technology for efficient and seamless file sharing.

How to Get Started with Torrenting:

Choosing the Right Torrent Client: To begin your torrenting journey, you’ll need a reliable torrent client. There are several options available, but one popular choice is qBittorrent. It provides a user-friendly interface and robust features for managing your torrent downloads.
Acquiring the Magnet Link: To initiate a torrent download, you’ll need the magnet link associated with the desired file. Magnet links are often provided by software applications and can typically be found in their Downloads section or on dedicated websites for torrents.
Embrace the Power of Seeding: Once you’ve downloaded a file using a torrent, you have the opportunity to contribute to the torrenting ecosystem by seeding. Seeding involves keeping the downloaded content available for other users to download, thus reducing the reliance on centralized servers and ensuring the availability of the file in the torrent network.

Why Choose Torrenting?

Decentralization and Resilience: Torrenting eliminates the dependence on centralized servers, making it more resilient to server failures and bandwidth limitations. With a torrent, as the number of users increases, the overall download speed improves, ensuring efficient distribution of files even in high-demand scenarios.

#!/usr/bin/env bash

# Set the directories where your files are located
papers_dir=~/PhD/PDFs
ebooks_dir=~/Dropbox/eBooks

# Save find result to arrays
mapfile -t paper_array < <(find "$papers_dir" -type f \( -iname "*.pdf" -o -iname "*.djvu" \))
mapfile -t ebook_array < <(find "$ebooks_dir" -type f \( -iname "*.pdf" -o -iname "*.djvu" \))

# Combine the arrays into a single array
combined_array=("${paper_array[@]}" "${ebook_array[@]}")

# Check if the combined array is empty
if [[ ${#combined_array[@]} -eq 0 ]]; then
 echo "No files found in the specified directories."
 exit 1
fi

# Declare an associative array to store filenames and paths
declare -A files

# Populate the files array
for file_path in "${combined_array[@]}"; do
 filename=$(basename "$file_path")
 files["$filename"]=$file_path
done

# Generate a list of filenames for the selection menu
gen_list() {
 for file_name in "${!files[@]}"; do
 echo "$file_name"
 done
}

# Prompt the user to select a file
selected_file=$(gen_list | rofi -dmenu -i -sorting-method fzf -sort -no-custom -location 0 -p "Select File")

# Open the selected file using xdg-open
if [[ -n "$selected_file" ]]; then
 xdg-open "${files[$selected_file]}"
fi

Customization:

Now that the script is set up, you can customize it to fit your workflow:

Adjust the directory paths: Modify thepapers_dir and ebooks_dir variables to match the directories where your files are located. For example, you might have research papers in one directory and ebooks in another. Update these paths accordingly.
Add more file types: By default, the script searches for PDF and DJVU files. If you have files of different formats, such as EPUB or MOBI, you can modify the find commands to include those extensions as well.
Customize the selection menu: The script uses the rofi utility to display a selection menu. You can modify the options passed to the rofi command to change the appearance or behavior of the menu. Refer to the rofi documentation for more information on available options.

Conclusion

With this Bash script, selecting and opening PDF or DJVU files becomes a breeze. By customizing the directories, file types, and selection menu, you can adapt the script to your specific needs.

In our modern world, the Internet has become an overwhelming sea of information. But have we truly mastered the art of navigating it? While the Internet presents itself differently to each individual, we often find ourselves at the mercy of bloated interfaces and algorithms that dictate what we see. However, there is a time-tested solution that empowers us to take control of our information consumption: Rich Site Summary (RSS), also known as Really Simple Syndication. Let’s take a step back in time and explore the power of RSS.

The Savior from the Past: RSS

You may have noticed the distinctive orange RSS logo on various blogs. This logo represents a button that carries a link, allowing you to copy and save it to an RSS reader. An RSS reader is an application specifically designed to consume these feeds. By setting up an RSS reader, you can stay updated whenever a new post is published on a blog, a newspaper site, a YouTube channel, Reddit, or even your favorite Twitter accounts (although the process for Twitter can be a bit cumbersome). The initial setup may take some time, but the key benefit is that you regain control over the information you receive.

Embrace Freedom

By utilizing RSS, you liberate yourself from the clutches of algorithmic recommendations and personalized feeds. Instead, you become the curator of your own information sources. You decide which blogs, news sites, or channels to subscribe to, and you receive updates from them directly. This empowers you to break free from the echo chambers and filter bubbles that dominate the modern Internet landscape.

Choosing an RSS Reader

There are numerous RSS readers available, catering to different platforms and preferences. Personally, I use newsboat, which is available in the apt repository for my laptop, and the Feed Reader app, available on F-Droid, for my Android device. However, a simple search will reveal a wide array of choices, allowing you to find the reader that best suits your needs.

Shameless Plug: If you’ve found this blog post helpful and would like to stay updated, you can find my RSS link below. Simply copy it and add it to your preferred RSS reader. Stay connected and informed!

Conclusion:

Navigating the Internet doesn’t have to be a passive experience dictated by algorithms. With RSS, we can reclaim control over our information consumption. By using an RSS reader and subscribing to the sources we trust and enjoy, we break free from the limitations imposed upon us. Embrace the power of RSS and explore the wealth of information available on your terms. Happy browsing!

Organize Your Files Automatically: A Bash Script Based on Creation Date

Fri, 17 Sep 2021 00:00:00 +0000

In today’s digital age, managing and organizing files can quickly become overwhelming. Locating specific files can be a time-consuming task, especially when dealing with a large number of documents, photos, or other digital assets. To streamline your file organization process, I’ve developed a bash script that automatically classifies files into respective year and month folders based on their creation date. This script simplifies file management and ensures a well-organized file structure. Let’s dive into the details of this handy script!

#!/usr/bin/env bash

# Create a folder structure to classify files by YEAR and MONTH.
# Aliased as 'sortdate'

for file in *; do
 if [ -f "$file" ]; then
 filename="$file"
 year=$(date -r "$file" +%Y)
 month=$(date -r "$file" +'%m %B')
 destination="$year/$month"

 mkdir -p "$destination" && mv "$filename" "$destination"
 fi
done

Explanation:

The script revolves around a for loop that iterates through each item in the current directory. It performs the following steps:

File Validation: The script verifies if the item is a regular file using the [ -f “$file” ] condition. This ensures that only files are considered for classification, excluding directories and other special files.
Extraction of Date Information: The date command is utilized to extract the creation date of the file. The date -r option retrieves the creation date of the file specified by $file. Two variables, year and month, are assigned the extracted year (+%Y) and month (+%m %B) respectively. The latter format includes both the month number and the full month name for better folder naming.
Destination Folder Creation: The destination folder path is constructed by concatenating the year and month variables. The mkdir -p command is used to create the destination folder if it doesn’t already exist. The -p flag ensures that parent directories are created as needed.
File Movement: The mv command moves the file ($filename) to the destination folder ($destination).

Conclusion: By utilizing this script, you can automate the process of organizing files based on their creation date. This simplifies file management and allows for easier access to specific files within a well-structured directory hierarchy. Whether you want to organize documents, photos, or any other files, this script will save you time and effort.

Note: When running scripts, exercise caution and ensure you have a backup of your files before making any changes to their locations.

Enhancing Your Vim Workflow: Tips and Configurations

Mon, 21 Jun 2021 00:00:00 +0000

Vim is a powerful text editor that can revolutionize your workflow with its extensive customization options. In this blog post, we’ll explore some useful tips and configurations to enhance your Vim experience.

Searching in Vim

Efficient searching is crucial in any text editor. To optimize your search experience in Vim, consider making the following changes to your configuration:

set nohlsearch
set incsearch
set ignorecase " case insensitive searching
set smartcase " case-sensitive if expresson contains a capital letter

nnoremap n nzzzv
nnoremap N Nzzzv

" Adding Fuzzy search for files
set path+=**

" For creating a tag file using ctags. Works with tex and programfiles.
" For more details see man page of ctags.
command! MakeTags !ctags -R .

These settings ensure that search highlights are not persistent, enable incremental searching, and set case-insensitive searching as the default behavior. The smartcase option allows Vim to perform case-sensitive searches if the search pattern contains at least one capital letter. Additionally, the provided nnoremap commands center the screen after jumping to the next/previous match, improving visibility.

Making pdf’s using Latex

If you work with LaTeX, you can streamline the process of compiling LaTeX files and generating PDFs using Vim. Here’s how:

Create a shell script named makepdf.sh with the following content:

#!/bin/bash
#Making pdf from anything.
file=$(readlink -f "$1")
dir=${file%/*}
base="${1%.*}"

cd "$dir" || exit 1

command="pdflatex"
( head -n5 "$file" | grep -qi 'xelatex' ) && command="xelatex"
( head -n1 "$file" | grep -qi 'handout' ) && $command --output-directory="$dir" --jobname="$base""_handout" "\PassOptionsToClass{handout}{beamer} \input{$base}" && bibtex "$base""_handout.aux" 
$command --output-directory="$dir" "$base" &&
bibtex $base.aux
$command --output-directory="$dir" "$base"
( head -n1 "$file" | grep -qi 'handout' ) && $command --output-directory="$dir" --jobname="$base""_handout" "\PassOptionsToClass{handout}{beamer} \input{$base}"

This script checks if the file can be converted to PDF using LaTeX or XeLaTeX, depending on whether xelatex is mentioned in the first 5 lines of the document. It also handles the creation of separate PDFs for beamer handouts if specified.

Add the following lines to your .vimrc file to create mappings for triggering the script:

autocmd FileType tex map <Leader>c :!~/scripts/makepdf.sh % <CR><CR>
autocmd FileType tex map <Leader>o :!zathura %:r.pdf & <CR><CR>

These mappings assign the <Leader>c and <Leader>o keys to compile the current LaTeX file and open the resulting PDF in the Zathura PDF viewer, respectively.

With these configurations, you can quickly compile your LaTeX files and preview the generated PDF without leaving Vim.

Utilizing Helpful Plugins

Vim plugins extend its functionality and allow you to tailor the editor to your specific needs. While it’s essential to be selective with the plugins you use, a few can significantly enhance your editing experience. Here’s an example setup using the popular plugin manager vim-plug and some recommended plugins:

"Plugins
call plug#begin('~/.vim/plugged')
	Plug 'VundleVim/Vundle.vim'
	Plug 'sirver/ultisnips'| Plug 'honza/vim-snippets'
	Plug 'tpope/vim-surround'
	Plug 'tpope/vim-commentary'
	Plug 'junegunn/vim-easy-align'
call plug#end()

The above configuration sets up vim-plug as your plugin manager and includes some useful plugins:

UltiSnips and vim-snippets provide powerful snippet capabilities, allowing you to assign keystrokes for commands and custom text snippets. They come with predefined snippets for various languages, saving you time and effort.
vim-surround simplifies working with surroundings (such as parentheses, quotes, HTML tags) by providing intuitive mappings to add, change, and delete them.
vim-commentary allows you to comment out lines or visually selected blocks of code with ease, enhancing code readability and simplifying commenting tasks.
vim-easy-align provides a straightforward way to align text and symbols within a line or across multiple lines, making your code more organized and visually appealing.
Remember to choose plugins that align with your specific needs and avoid overloading Vim with unnecessary extensions.

Automating Workflow with Helpful Automatic Commands

In addition to the previously mentioned tips and configurations, there are some additional automatic commands that can further enhance your Vim workflow. These commands automate certain actions based on specific events. Let’s explore two examples:

Remembering Folds:

augroup remember_fold
autocmd!
autocmd BufWinLeave * mkview
autocmd BufWinEnter * silent! loadview
augroup END

The above commands define an autocmd group named “remember_fold.” This group ensures that the state of your file’s folds (collapsed or expanded) is saved when you switch away from the buffer and restored when you return to it. This feature is especially useful when working with large files or projects where you frequently navigate between different buffers.

Automatic Execution of Shell Script on Quit for Texfiles:

augroup autocom
 autocmd!
 autocmd VimLeave *.tex !~/scripts/texclear.sh %
 autocmd VimLeave *.tex !~/scripts/texclear.sh %:r_handout.tex
augroup END

These commands define an autocmd group named “autocom.” It specifies that when you quit Vim while editing a .tex file, the shell script texclear.sh will be executed automatically to clear the build files associated with the LaTeX/XeLaTeX build. This cleanup ensures that unnecessary files generated during compilation are removed, keeping your project directory clean.

The texclear.sh script is as follows:

#!/bin/sh

# Clears the build files of a LaTeX/XeLaTeX build.
# I have Vim run this file whenever I exit a .tex file.

case "$1" in
 *.tex)
 file=$(readlink -f "$1")
 dir=$(dirname "$file")
 base="${file%.*}"
 find "$dir" -maxdepth 1 -type f -regextype gnu-awk -regex "^$base\\.(4tc|xref|tmp|pyc|pyo|fls|vrb|fdb_latexmk|bak|swp|aux|log|synctex\\(busy\\)|lof|lot|maf|idx|mtc|mtc0|nav|out|snm|toc|bcf|run\\.xml|synctex\\.gz|blg|bbl)" -delete ;;
 *) printf "Give .tex file as an argument.\\n" ;;
esac

This script clears the unnecessary build files associated with a LaTeX/XeLaTeX compilation. When you exit Vim after editing a .tex file, the script identifies the relevant build files based on the file’s name, removes them, and ensures a clean workspace for your next LaTeX project.

By incorporating these automatic commands, you can streamline your workflow and focus more on your content creation rather than manual housekeeping tasks.
