I was looking into some of octosql 's benchmarks the other day and noticed a large chunk of time in DataStation / dsq is spent in encoding JSON objects. JSON is an intermediate format in DataStation and it's pretty inefficient. But the reason it's used is because almost every scripting language supported by…
Advanced Web Application Architecture allows you to spot what kind of code you're dealing with:
Post-mortem report for the outage on July 13th and 14th 2022
I’ve been experimenting with different approaches to running code in a sandbox for several years now, but my latest attempt feels like it might finally have all of the characteristics …
The first computer I used had about 2KB of RAM. The other day, I compiled a 2KB Common Lisp script into a 16MB executable to get its startup (and total execution) time down from 2s to subjectively instantaneous — and that didn't bother me the least, for my current computer has 8GB of working memory…
GCC now uses C++ as its implementation language. This means that to build GCC from sources, you will need a C++ compiler that understands C++ 2003. For more details on the rationale and specific changes, please refer to the C++ conversion page.
The Cargo team have been thinking about and discussing long-term plans for Cargo. In this post I'll talk about what we hope Cargo will look like around the time of the next edition (assuming there is another edition and that it happens in about three years, neither of which is
Vim 8 added a native way to load third-party packages. This means, for me at least, there is no longer any need to use a third party plugin helper like Pathogen.
Stars! is a 1995 4X game (explore, expand, exploit, exterminate) for 16-bit Windows 3.1 that I first played ~28 years ago. While Windows is famously backwards compatible, it’s notoriously difficult to play Stars! today. Windows x64 cannot run 16-bit applications, and playing requires either retro hardware or emulation…
Miguel de Icaza's Blog
Lately, I’ve been reading articles about best practices for code reviews. I notice that these articles focus on finding bugs to the exclusion of almost every…
Edit 2017/12/10: So I screwed up, I thought I was safe confirming it in two different ways but I was using an external monitor and all of the below is accurate only for a specific multi-monitor case. Skip to the bottom to read about my new results.
QBE 1.3 took a while to cook, but it is the most significant release since 1.0 with around 7k new lines of code and 1.5k deleted ones. In addition to the usual bug fixes, QBE gained a new and original IL matching algorithm, new optimizations from Roland Paterson-Jones, Scott Graham added support for the Windows ABI…
Static Single Assignment is a program representation where each “variable” (though this term can be misleading) is assigned exactly once. Mostly the variables aren’t variables at all, but instead names for values—for expressions. SSA is used a lot in compilers. See this lesson from Cornell for converting Bril to SSA…
This semester, I am teaching Compilers , and I'm quite happy with how I covered parsing this year. Specifically, I taught students to build a top-down LR parser and it seemed to go relatively well.
Blog about Ubuntu from a kernel engineer
The halting problem asks whether the execution of a specific program for a given input will terminate.
tl;dr: I have created a test suite for comparing the transaction isolation levels in different databases. I did this as background research for my book . This post explains why.
I spotted a new (to me) pattern which I think is pretty interesting: projects are bundling compiled binary applications as part of their Python packaging wheels. I think it’s really …
I've been enjoying teaching Intelligent Systems again this semester. A big part of the fun is re-reading old papers. I had a lot of fun re-reading and thinking about the ideas in William Clancey 's classic paper, Heuristic Classification . Long-time readers may recall me mentioning this paper in a long-ago post about…
Today, we are happy to announce FastCGI support for HHVM. FastCGI is a popular protocol for communication between an application server (e.g. running your PH...
In 2018, I wrote an article “Writing an efficient Vulkan renderer” for GPU Zen 2 book, which was published in 2019. In this article I tried to aggregate as much information about Vulkan performance as I could - instead of trying to focus on one particular aspect or application, this is trying to cover a wide range of…
Ideally, you’d want your program to work everywhere. Unfortunately, that’s not that simple, even if you’re using high-level “portable” languages such as Python. In thi…
We introduce PaperBench, a benchmark evaluating the ability of AI agents to replicate state-of-the-art AI research.
The challenge, simulate millions of particles in golang, multi-player enabled, cpu only, smart tv compatible.
Left & Mutual Recursion Mitigation
I have a lot in the works for the this month's Logic for Programmers release. Among other things, I'm completely rewriting the chapter on Logic Programming...
