In this post, Phillip talks through the challenges & pitfalls of LLMs we faced when building our Query Assistant - and that you too may face.
Async Rust is a whole new world of programming. Let's try to understand it by working our way through a series of web servers, learning the details of concurrency and I/O along the way.
Much has been written on Common Lisp; there is rarely one year without someone proclaming the death of the language and how nobody uses it anymore. And yet it is still here, so something must have…
The world’s code is now at your fingertips.
Curious what the first ‘unused’ alphabetic acronym is, I have GPT-4 write a script to check English Wikipedia. After three bugs, the first unused one turns out as of 2023-09-29 to be the three-letter acronym ‘CQK’, with another 2.6k TLA unused, and 393k four-letter acronyms unused. Exploratory analysis suggests…
We’re pleased to announce that support for the declarative shadow DOM API has been added and enabled by default in Safari Technology Preview 162.
Loro, our high-performance CRDTs library, is now open source. In this article, we share our vision for the local-first software development paradigm, why we're excited about it, and the current status of Loro.
In this article, previously part of my new book, we look at the introduction of .NET Core, why it was created, and how it has evolved into .NET 7.
The second part of a three part look at new features in Go 1.20.
OCaml with Jane Street extensions is available from our public opam repo. Only a slice of the features described in this series are currently implemented.
“640K ought to be enough for anybody.” - Supposedly Bill Gates, circa 1981.
We are reverting this change for now. More details to follow. The default compression for Git archives has recently changed. As result, archives downloaded from GitHub may have different checksums…
Every day, thousands of developers at Meta are working in repositories with millions of files. Those developers need tools that help them at every stage of the workflow while working at extreme sca…
I recently implemented a Brainfuck interpreter in the Crystal programming language and I’d like to share my honest opinion about working in the language.
In April 2021, the Vulkan® Working Group at Khronos® released a set of provisional extensions, collectively referred to as ‘Vulkan Video’ which provide seamless encoding and decoding of video streams using a variety of video coding standards. The December 2022 release of Vulkan 1.3.238 saw the finalization of the…
A lot of people ask us the question, why do we choose to use Common Lisp as our primary development language? Often times the question comes disguised as a suggestion: "Flask is a great webserver you should consider using". This is a well intentioned suggestion- of course we would like to use the best tools available!…
Minor terminological nitpick. People often describe the LLM as ‘hallucinating’ information whenever it makes up information which seems like it should fit for a given query even when it is trivially false. While evocative, this isn’t actually correct terminology. We already have a perfect word for this precise…
Sometimes you have a lot of data, and one approach to support quick searches is pre-processing it to build an index so a search can involve only looking at a small fraction of the total data. The threshold at which it's worth switching to indexing, though, might be higher than you'd guess. Here are some cases I've…
Understand how using UUIDs as primary keys can affect PostgreSQL performance, and how to tweak your index to avoid UUID performance pitfalls.
Codon is a new tool that compiles Python code to run it more efficiently and effectively while allowing for customization and adaptation to various domains.
Using DISTINCT to fix duplicate rows from a SQL join is a common antipattern. It generates all the duplicates first, then sorts them away - hurting performance. Learn how to rewrite these queries using EXISTS for cleaner, faster SQL Server results.
“shouldn’t this have been published a few months ago?” yeah, probably. I even considered submitting it to the AoC contest. time is a real beast. The title is clickbait. I did not design and implement a programming language for the sole or even primary purpose of leaderboarding on Advent of Code. It just turned out…
I can mathematically prove the game's not fun.
Emacs 29 introduces tree-sitter support, a powerful parsing library that enhances its understanding of source code. With this integration, Emacs gains features like precise syntax highlighting, accurate indentation and easier extensibility. Here's how you install and configure Emacs with tree-sitter support.
I implemented new --shuffle option for GNU make to simulate non-deterministic build order in parallel makefiles.
The pganalyze Indexing Engine simulates hundreds of possible combinations to recommend missing Postgres indexes using its 'What if?' analysis.
