We’re happy to announce a new release of ClojureScript. If you’re an existing user of ClojureScript please read over the following release notes carefully, there are two very significant changes. First, ClojureScript now ships with greatly enhanced support for integration with popular JavaScript bundling tools such as…
This year Java hit an incredible milestone and reached the grand old age of 25 years. We celebrated its jubilee by running a special online Java day event, where lots of expert speakers shared their e
Unless you live under one of the few rocks that still lack Internet access, you’ve probably already heard of an “event queue” . If not, maybe “message queue”, or “event loop”, or “message pump” rings a bell. To refresh your memory, let’s walk through a couple of common manifestations of the pattern.
Something I’ve been thinking about recently is how when I’ve worked on any kind of distributed system, including systems as simple as a web app with frontend and backend code, probably upwards of 80% of my time is spent on things I wouldn’t need to do if it weren’t distributed. I came up with the following description…
The Lumen Project is an alternative implementation of the Erlang VM, more known as the BEAM. It is designed to work in WebAssembly with the specific goal of bringing Elixir and Erlang to the browser.
This is the blog version of a talk I gave on the 2017-12-13 at the Athens Clojure Meetup, which was kindly hosted by Skroutz . The video of the talk is available (the talk was given in Greek, but there are English subtitles). This blog entry is not an exact transcript of the talk, I've added links and more information…
How the JPEG format works: file headers and markers, Huffman coding, quantization, zigzag and the DCT, explained by writing a JPEG decoder in Python.
Welcome, This is the index page for my "Reverse engineering the rendering of The Witcher 3" small series where I select some rendering tec...
Some time ago, I wrote a blog post about how there’s more to a pointer than meets the eye. One key point I was trying to make is that just because two pointers point to the same address...
We’re very excited to release Pyston v2, a faster and highly compatible implementation of the Python programming language. Version 2 is 20% faster than stock Python 3.8 on our macrobenchmarks…
Haskell programmers spend a lot of time talking about type safety . The Haskell school of program construction advocates “capturing invariants in the type system” and “making illegal states unrepresentable,” both of which sound like compelling goals, but are rather vague on the techniques used to achieve them. Almost…
Looking for sponsorship Apple now ships Macs which are running on an arm64 variant machine with the latest version of MacOS, Big Sur M1. ...
Deno 1.4 adds support for the web standard WebSocket API, deno run --watch, and integrated test coverage. This is the largest feature release yet.
Context It’s not often I get excited about programming languages since meeting Ruby in 2015. Way before that, drowning in misery of writing university course works in Java, has pushed me away from development. Ruby’s freedom and expressiveness was what pulled me back, and its style has kept me in. I was on the lookout…
An in-depth look at Data-Oriented Architecture (DOA): monolithic data stores vs microservices, scaling benefits, and real-world case studies.
I booted the arm64e kernel of macOS 11.0.1 beta 1 kernel in QEMU up to launchd. It’s completely useless, but may be interesting if you’re wondering how an Apple Silicon Mac will boot.
A couple of years ago, I started my first job as a programmer. On the first day, I entered the office, sat in my new chair, turned on the computer, checked out a project from the version control system and opened it in IDE. The first-ever piece of the code I saw looked like that: // TODO it works, but it's ugly…
Over the last year, my 13 year old nephew developed a love for hacking. From anime chat , to snake , a minimal twitter , a blog , to an anime music startup , he’s built some cool stuff (1). What I’m most proud of though, is that he’s done this with self directed play, rather than with a rigid curriculum.
A look into how Python is used to bring your favorite movies to the big screen.
At WWDC 2020 earlier this year, Apple announced a transition from Intel to ARM-based processors in their laptops. This blog is about the prospects of when R will work on that platform, based on experimentation on a developer machine running A12Z, one of the “Apple silicon” processors.
It is commonly believed, wrongly, that Cap’n Proto doesn’t support “streaming”, in the way that gRPC does. In fact, Cap’n Proto’s object-capability model and promise pipelining make it much more expressive than gRPC. In Cap’n Proto, “streaming” is just a pattern, not a built-in feature.

Last year (2019), we released the simjson library. It is a C++ library available under a liberal license (Apache) that can parse JSON documents very fast. How fast? We reach and exceed 3 gigabytes per second in many instances. It can also parse millions of small JSON documents per second. The new version is much ……
A few minutes ago I came across a Hacker News post that detailed a method of adding search to your static site. As you probably know, adding search to a static site is a bit tricky, because you can’t just send the query to a server and have the server process it and return the results. If you want full-text search…
Last week I was trying to add some testing code to libsecp256k1 and I was pulling out my hair trying to get it to work. No amount of printf was working to illuminate what I was doing wrong. Finally, out of desperation, I thought I would do a quick check to see if there are any compiler bugs related to memcmp , and lo…
