Starting with a 192-byte one-liner that implements a Reverse Polish Notation arithmetic compiler, we'll work backward to transform it into readable JavaScript by removing one code golf trick at a time
Swift is heavily used in production for building cloud services at Apple, with incredible results. Last year, the Password Monitoring service was rewritten in Swift, handling multiple billions of requests per day from devices all over the world. In comparison with the previous Java service, the updated backend…
Understand how using UUIDs as primary keys can affect PostgreSQL performance, and how to tweak your index to avoid UUID performance pitfalls.
Explore the Qt Blog for the latest insights on e.g. Qt Creator, your go-to source for cross-platform development tips and updates.
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.
At Shopify, we’re keeping the flexibility of untrusted Partner code, but executing it on our own infrastructure with WebAssembly.
Light Table 0.7.0 just went out, and in addition to being a fairly major update, we’ve got some fairly major news to accompany it. Some people expressed concern after Chris’s blog post about Eve that Light Table was being abandoned or forgotten, but hopefully some of the announcements today can assuage those concerns…
Earlier this year we made the AWS SDK developer guides available as GitHub repos (all found within the awsdocs organization) and invited interested parties to contribute changes and improvements in the form of pull requests. Today we are adding over 138 additional developer and user guides to the organization, and we…
A delightful language with friendly error messages, great performance, small assets, and no runtime exceptions.

Since we originally proposed the need for a first-class language, compiler and ecosystem for machine learning (ML), there have been plenty of interesting developments in the field. Not only have the tradeoffs in existing systems, such as TensorFlow and PyTo...
If this were a diary it would have a unicorn on the cover, because unicorns are awesome.
A little over a month after releasing Bevy 0.2, and thanks to 59 contributors, 122 pull requests, and our generous sponsors, I'm happy to announce the…
The pganalyze Indexing Engine simulates hundreds of possible combinations to recommend missing Postgres indexes using its 'What if?' analysis.
Get to know and learn how to use some less-known features of Version 12 of PostgreSQL. You'll surely discover something new for yourself.
We're very excited to announce official support for Clojure, going into public beta as of today. Clojure is the third official language supported by Heroku
Supporting a programming language at Meta is a very careful and deliberate decision. We’re sharing our internal programming language guidance that helps our engineers and developers choose the best…
The library for web and native user interfaces
One of my recent hobby projects was a blocks-based tool for doing basic data science , and I was very pleased when its test suite reached 100% line coverage. However, Inozemtseva2014 found that code coverage is a poor predictor of how effective a test suite is at detecting bugs once the size of the test suite is…
Up until now, GraalVM has offered two ways to run Java programs: using the Java HotSpot VM with the GraalVM JIT (just-in-time) compiler…
Chrome engineers are experimenting with Rust. For the foreseeable future, C++ is the reigning monarch in our codebase, and any use of Rust will need to fit in with C++ — not the other way around. This seems to present some C++/ Rust interoperability challenges which nobody else has faced.
We are standardizing OpenAI’s deep learning framework on PyTorch.
