Enhance the Java programming language with string templates . String templates complement Java's existing string literals and text blocks by coupling literal text with embedded expressions and template processors to produce specialized results. This is a preview language feature and API .
The original NMOS version of the MOS 6502, used in computers like the Commodore 64, the Apple II and the Nintendo Entertainment System (NES), is well-known for its illegal opcodes: Out of 256 possible opcodes, 151 are defined by the architecture, but many of the remaining 105 undefined opcodes do…
Rethinking ‘rethinking reactivity’
Introduce an API by which Java programs can interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the JVM), and by safely accessing foreign memory (i.e., memory not managed by the JVM), the API enables Java programs to call native libraries and…
Developers can now integrate GPT‑3.5 Turbo and Whisper models into their apps and products through our API.
Many programming "best practices" taught today are performance disasters waiting to happen.
An homage to Aphyr's Typing the technical interview
Go 1.21 shipped a preview of a change in Go 1.22 to make for loops less error-prone.
From the Zed Blog: A deep-dive into the graphical underpinnings of GPUI, the hardware-accelerated framework that powers Zed's user interface.
This article explains how to correctly handle filenames in Bourne shells (the primary shell of Unix/Linux/POSIX systems), based on the issues discussed in 'Fixing Unix/Linux/Filenames'. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because…
The Apple Macintosh combined brilliant design in hardware and in software. The drawing program MacPaint, which was released with the computer in January of 1984, was an example of that brilliance both in what it did, and in how it was implemented.
One of the least well known, and therefore least used, features of many terminal emulators is bracketed paste mode . When you are in bracketed paste mode and you paste into your terminal the content will be wrapped by the sequences \e[200~ and \e[201~ .
Customers and stakeholders have substantial investments in, and are comfortable with the performance, security and stability of, industry-standard platforms like the JVM. While Java developers may envy the succinctness, flexibility and productivity of dynamic languages, they have concerns about running on…
Implementing a GPT model from scratch in NumPy.
Anyone who’s spent any amount of time on the Internet has a good idea of how prevalent meme usage has become in online discourse. Finding new memes on the latest happening and sharing them with various friend groups to share in the humor is a long-enjoyed pastime of mine. Working in tech and in the InfoSec field has…
A look at what went into building the world's largest public code search index.
From time to time, someone shows that in JavaScript the .length of a string containing an emoji results in a number greater than 1 (typically 2) and then proceeds to the conclusion that haha JavaScript is so broken—and is rewarded with many likes. In this post, I will try to convince you that ridiculing JavaScript for…
Prompt Engineering, also known as In-Context Prompting, refers to methods for how to communicate with LLM to steer its behavior for desired outcomes without updating the model weights. It is an empirical science and the effect of prompt engineering methods can vary a lot among models, thus requiring heavy…
In this post, I’ll iteratively optimize an implementation of matrix multiplication written in CUDA.My goal is not to build a cuBLAS replacement, but to deepl...
Now for something completely different. In the spiritual vein of One Night in Rio: Vacation photos from Plan9 and AWK for multimedia, here is a tool that is the link that ties almost all the projec…
This one time, at Intel, I wrote a compiler...

This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines?
Async/await syntax in Rust was initially released to much fanfare and excitement. To quote Hacker News at the time:
YJIT’s ability to improve performance by adapting to run-time behavior can increase the speed of our code in a way that dropping down to C can’t. As such, I think we should reconsider the common wisdom that “rewriting our Ruby in C” is the ideal path to performance optimization and take a serious look at “rewriting…
There are two types of programming languages: garbage-collected programming languages and programming languages that require manual memory management. With to WebAssembly Garbage Collection, garbage-collected languages can be ported to WebAssembly.
