How to Use Markdown

Whether you're posting on Reddit, Discord, or Github, there's only one way to add formatting: Markdown. If you want to add a link, bold some text, or even split text into paragraphs, you will need to know the basics of this text-based formatting system. Does that sound scary? Trust me, it’s not. Markdown has just a few rules for formatting text the way you want, and you only need to learn the rules for the formatting you actually use. Let's go over the simple rules, talk about why Markdown is

FBI: Cybercriminals steal health data posing as fraud investigators

The Federal Bureau of Investigation (FBI) has warned Americans of cybercriminals impersonating health fraud investigators to steal their sensitive information. As the federal law enforcement agency cautioned in a Friday public service announcement, scammers posing as "legitimate health insurers and their investigative team members" are emailing or messaging potential victims to pressure them into providing personal or health data that can later be used for fraudulent purposes.

Community Is Motivation on Tap

Community is Motivation on Tap A good community can have tremendous influence on one’s motivation. I never appreciated this fact enough so I wanted to write about it here. Looking at successful athletes, founders, musicians, game speedrunners, or overachievers in any area, they seem to have unlimited motivation to do loads of tedious work or practice. One might say they are interested in the work itself, but how inherently interesting can beating super mario 1ms faster be? The work of a founde

Evaluating Long-Context Question and Answer Systems

While evaluating Q&A systems is straightforward with short paragraphs, complexity increases as documents grow larger. For example, technical documentation, novels and movies, as well as multi-document scenarios. Although some of these evaluation challenges also appear in shorter contexts, long-context evaluation amplifies issues such as: Information overload: Irrelevant details in large documents obscure relevant facts, making it harder for retrievers and models to locate the right evidence for

PNG image format receives HDR and animation support in first spec update in decades

Why it matters: For decades, JPEG, PNG, and GIF have remained among the most popular image formats, even as newer options like WebP and AVIF have emerged. Now, PNG is getting its first meaningful update in over 20 years with the release of its third edition, making the format more versatile than ever. The World Wide Web Consortium (W3C), which manages web standards and guidelines, recently published new specifications for the PNG (Portable Network Graphics) image format. The updated format now

Mixed DPI in X11

I'm writing this article because I'm getting tired of repeating the same concepts every time someone makes misinformed statements about the (lack of) support for mixed-DPI configurations in X11. It is my hope that anybody looking for information on the subject may be directed here, to get the facts about the actual possibilities offered by the protocol, avoiding the biased misinformation available from other sources. If you only care about “how to do it”, jump straight to The RANDR way, otherwi

These Three Messaging Apps Are Encrypted, but One Stands Above the Rest

Key points: Most widely used messaging app Uses the same encryption protocol as Signal Collects heaps of your data Free, but owned and operated by Meta WhatsApp is the most popular private messaging app on this list, with about 2 billion monthly users, according to Exploding Topics. Because it's so popular, there's a higher chance that other people you might be chatting with have WhatsApp, and therefore your chats can be encrypted. And if the person you're chatting with doesn't have WhatsAp

'Cyber plague': Experts warn of growing infostealer threat after billions of login details exposed

"Someone, somewhere is having data exfiltrated from their machines as we speak," says Volodymyr Diachenko, co-founder of the cybersecurity consultancy SecurityDiscovery.

An analysis done in collaboration with Privacy Rights Clearinghouse (PRC) found that many data brokers hav

Information has been permanently deleted, for small values of permanently

As part of a periodic purge of unused online accounts, I deleted my account from a company ten months ago. Let’s call that company Contoso. I received a confirmation that said, “Your personal information and items associated with your account have now been deleted. This action is permanent and cannot be reversed.” Yesterday, I got an email from Contoso informing me that they have updated their Privacy Policy. So I guess their “confirmation” of “permanent” and “irreversible” deletion of my pers

Rita El Khoury / Android Authority TL;DR An upcoming release of Google Home could soon support Outdoor Weather and Outdoor AQI information in the Favorites tab. Adding the information to the Favorites tab will allow users to quickly control their smart home devices based on current weather conditions. Google recently upgraded the Google Home app with a ton of new features and upgrades, including the ability to set device-specific favorites. All of these work great, but there’s always room for

Tesla launches robotaxi rides in Austin with big promises and unanswered questions

Tesla has started giving rides in driverless Model Y SUVs in Austin, a decade after CEO Elon Musk began making — and breaking — myriad promises about his company’s ability to launch such a service. The rollout will become the first big test of Musk’s belief that it’s possible to safely deploy fully autonomous vehicles using just cameras and end-to-end AI – an approach that differs from other players in the space like Waymo. On Sunday, numerous videos shared on social media as well as sources i

Writing documentation for AI: best practices

Retrieval-Augmented Generation (RAG) systems like Kapa rely on your documentation to provide accurate, helpful information. When documentation serves both humans and machines well, it creates a self-reinforcing loop of content quality: clear documentation improves AI answers, and those answers help surface gaps that further improve the docs. This guide provides best practices for creating documentation that works effectively for both human readers and AI/LLM consumption in RAG systems. Many bes

Why JPEGs still rule the web (2024)

A version of this post originally appeared on Tedium, Ernie Smith’s newsletter, which hunts for the end of the long tail. For roughly three decades, the JPEG has been the World Wide Web’s primary image format. But it wasn’t the one the Web started with. In fact, the first mainstream graphical browser, NCSA Mosaic, didn’t initially support inline JPEG files—just inline GIFs, along with a couple of other formats forgotten to history. However, the JPEG had many advantages over the format it quickl

According to the report, police found the names of 11 registered data brokers written in a notebook that was recovered from Boelter’s vehicle. He also allegedly wrote, “most property records in Ame

Windows 10 EOL

Blog Windows 10 EOL June 17th, 2025 (permalink) So Microsoft decided to produce tons of e-waste for no obvious reason. There's a lot of capable hardware out there, and it would be of software company's interest to support as much hardware as possible. Instead, they made some arbitrary reason to deprecate "old" hardware. At the same time they also turned all of windows VR headsets into garbage. We'll have to wait for the open source implementations to catch up for any hope of them being usable

What I talk about when I talk about IRs

I have a lot of thoughts about the design of compiler intermediate representations (IRs). In this post I’m going to try and communicate some of those ideas and why I think they are important. The overarching idea is being able to make decisions with only local information. That comes in a couple of different flavors. We’ll assume that we’re compiling a method at a time, instead of a something more trace-like (tracing, tracelets, basic block versioning, etc). Control-flow graphs A function wi
