Abusing Go's infrastructure
I apologize if this information is already known, but I couldn’t find any references about it and I wanted to understand what was going on and share with you because I think there is some value doing it. In case this wasn’t known, I apologize to the Go team for not talking to them first and jumping the full disclosure gun (I don’t think it’s that severe). I really like Go! Thanks for all your grea
Just over a year ago, NewJeans made their surprise debut with the suitably titled single Attention. Shortly after, the K-pop five-piece’s self-titled New Jeans EP dropped and since then they’ve been on a continually meteoric ascent – only bolstered by the club-fuelled pop of their recent release Get Up. Made up of members Minji, Hanni, Danielle, Haerin and Hyein, NewJeans channel an energy akin to
Dart 3.1 & a retrospective on functional style programming in Dart 3
Diff of a Dart 3 refactor using functional style features within Dart’s internal code baseToday we’re releasing Dart 3.1, our first stable release since the major Dart 3.0 release in May. Dart 3.1 contains a handful of minor updates and a few API adjustments to further use class modifiers introduced in 3.0 (which you can read more about in the changelog). Mostly, though, we’ve been spending our ti
Personal A Microcosm of the interactions in Open Source projects Saturday, March 30, 2024 Originally a thread on Twitter about the xz/liblzma vulnerability, when I finished typing it, I realized I had a real world slice of Open Source interaction that deserved more attention. There will be lots of analysis of the xz/liblzma vulnerability. However, I’ve found most skip over the first step of the at
How a startup loses its spark
At a well-run seed stage startup, engineers will often describe the work experience as intoxicating. At a larger company, the best you get is "enjoyable". Why does this happen? Is it inevitable? Let's inspect what makes a startup intoxicating. An engineer should spend most of their time in this core loop: If needed, talk to users, figure out their problems. Come up with an idea to build. If needed

Accelerating Generative AI with PyTorch: Segment Anything, Fast
This post is the first part of a multi-series blog focused on how to accelerate generative AI models with pure, native PyTorch. We are excited to share a breadth of newly released PyTorch performance features alongside practical examples of how these features can be combined to see how far we can push PyTorch native performance. As announced during the PyTorch Developer Conference 2023, the PyTorc
About That Mysterious AI Breakthrough Known As Q* By OpenAI That Allegedly Attains True AI Or Is On The Path Toward Artificial General Intelligence (AGI)
Seems hard to believe that the number of people likely knowing this fantastical outcome would be utterly secretive and mum for any considerable length of time. The seemingly more plausible notion is that they arrived at a kind of AI that shows promise toward someday arriving at AGI. You could likely keep that a private secret for a while. The grand question though looming over this would be the cl
Introducing FireDBG for Rust | FireDBG - 🔥 Time Travel Visual Debugger for Rust
Debugging programs is hardDebugging programs is hard. It is extremely mind boggling when something does not work as expected. More often than not 90% of the work is on tracking down where the bug is, and 10% is actually solving it! But why don't programmers use debuggers more often these days? Instead, we all enjoy adding println all over the place, running the program, adding more prints, rinse
Island management is a fundamental low level feature of physics engines and can have a big impact on solver design and performance. This was one of the first problems I decided to work on for Box2D version 3 (v3). Since I began working on v3 I've been comparing several algorithms for island management. My goal has been to make island building scale better with multiple CPU cores. Here are the thre

Unification in Elixir
Pattern matching is a pervasive and powerful tool in Elixir. This isn't too surprising if you know a little about the history of Elixir's parent language, Erlang. Erlang was originally inspired by and written in Prolog, a logic programming language where pattern matching has first-class support. In Elixir, you might see an expression like this: [x, [2, y]] = [1, [2, 3]]When this expression is eval
Digital Solution Offerings: Techniques to Deliver Success for Digitalization
When we talk about digital solution offerings, first of all, let’s discuss what digital solutions are, what are digitalization and digitization, and what are the needs for that. What is Digitalization Simply put, digitalization is the journey of shifting business activities – processes, data management, communication, and more – from paper to an online environment. It involves utilizing digital to
How to Choose Your Neighborhood in Japan: Location, Facilities, Noise, and More
Once you’ve decided on your new Japanese city, the next step to setting up a stable life in Japan is to discover a neighborhood that meets your needs. Thankfully, most Japanese neighborhoods are self-contained mini-towns bursting with activity and local businesses. However, in such a densely packed country, noise pollution and privacy will naturally be an issue no matter where you are, making it v
Kanban: A Project Management Approach to Software Development
Kanban is a popular agile project management framework. Kanban methodology shares a few similarities with Scrum, primarily in terms of its focus on early release through collaborative and self-management teams. The origin of the Kanban concept goes back to the production line of Toyota factories during the 1940s. Kanban methodology is highly visual. This visualization helps develop optimal results

Why if TYPE_CHECKING?
Dec 11 2023 I saw this tweet over the weekend and wanted to dive into the fundamental question behind this: Given this potential error, why do we use conditional imports at all, or, more specifically, when might we use this pattern? The TL;DR is that we use this pattern to hedge between the differences in typechecking enforced by mypy and typechecking as it happens at runtime, particularly when we

A lot of new CSS features have shipped in the last years, but actual usage is still low. While there are many different reasons for the slow adoption, I think one of the biggest barriers are our own brains.

Revealing Images With CSS Mask Animations — Smashing Magazine
Let’s play with images and experiment with CSS masks. The idea is fairly simple: take a single <img> tag and harness the power of CSS to accomplish complex hover transitions. Through different demos, you will see how CSS masks combined with gradients allow us to create fancy effects — with efficient, reusable code. In a previous article, we explored fancy hover effects for images that involve shin

For example, I've known about operational transformations (OT) for a while (via Quill, but I h

What O’Reilly Learning Platform Usage Tells Us About Where the Industry Is Headed This has been a strange year. While we like to talk about how fast technology moves, internet time, and all that, in reality the last major new idea in software architecture was microservices, which dates to roughly 2015. Before that, cloud computing itself took off in roughly 2010 (AWS was founded in 2006); and Agil
