In part two of this series we discussed data replication within the context of a distributed log and how it relates to high availability. Next, we’ll look at what it takes to scale the log such that it can handle non-trivial workloads. Data Scalability A key part of scaling any kind of data-intensive system is the…
The compiler tool chain is one of the largest and most complex components of any system, and increasingly will be based on open source code, either GCC or LLVM. On a Linux system only the operating system kernel and browser will have more lines of code. For a commercial system, the compiler has to be completely…
An exploration of NFL play-by-play statistics with Bokeh and Pandas.
How low we can Go and still do something useful? I recently bought this ridiculously cheap board: I bought it for three reasons. First, I have never dealt (as a programmer) with STM32F0 series. Second, the STM32F10x series is getting old. MCUs belonging to the STM32F0 family are just as cheap if not cheaper and has…
Today, as I announced earlier, the Corman Lisp 3.1 has been released after more than a decade-long break. Somehow it happened that I am one of the active mai...

A versioned Go command must decide which module versions to use in each build. I call this list of modules and versions for use in a given build the build list . For stable development, today’s build list must also be tomorrow’s build list. But then developers must also be allowed to change the build list: to upgrade…
In July 2017, I received a call from a former colleague asking me wether I wanted to begin a new app journey with him. The client would be Paris Turf, an editor specialized in horse races results. My lovely lovely lovely horse [1] They wanted to diversify and launch a
Zombies probably won’t consume 32 GB of your memory like they did to me, but zombie processes do exist, and I can help you find them and make sure that developers fix them. Tool source link is at t…
wingolog: article: lightweight concurrency in lua
(This essay is from the introduction to On Lisp .) It's a long-standing principle of programming style that the functional elements of a program should not be too large. If some component of a program grows beyond the stage where it's readily comprehensible, it becomes a mass of complexity which conceals errors as…
Python's GIL explained in Python code
I am writing Dora, a simple JIT-compiler with Rust. Dora is both the name of the custom programming language and of the JIT-compiler. After some time working on it, I want to write about the experiences I made. I started this project to get a better understanding of the low-level implementation details of a…
Multi-task learning - allowing a single agent to learn how to solve many different tasks - is a longstanding objective for artificial intelligence research. Recently, there has been a lot of excellent progress, with agents like DQN able to use the same algorithm to learn to play multiple games including Breakout and…
Three months ago, in Roadmap #5 , I wrote that OSH will be a better shell for building Linux distributions . It will run existing code, including bash scripts, but it's stricter and easier to debug.

One of the lesser known parts of Java is InterruptedException. With its vague-sounding name and non-committal Javadoc, few people are able to figure out what they need to do with it. Since I myself didn’t really grok it, I decided to put together a post explaining how interruption works. If you are looking for a more…
This is the first of a two-part series about Bayesian bandit algorithms. Check out the second post here. Let’s talk about Bayesianism. It’s developed a reputation (not entirely justified, but not entirely unjustified either) for being too mathematically sophisticated or too computationally intensive to work at scale…
