A question that is frequently occurring among my SQL training’s participants is: What’s the difference between putting a predicate in the JOIN .. ON clause and the WHERE clause? I can d…
Optimizing compilers are a mainstay of modern software: allowing a programmer to write code in a language that makes sense to them, while transforming it into a form that makes sense for the underlying hardware to run efficiently. The optimizing compiler's job is to figure out what your input program does, and create…
There is something very exciting I have to show to you today: a completely rewritten notification system for Plasma that will be part of our next feature update 5.16 to be released in June.
I had been programming in Fortran and assembler for a number of years when I got my first personal computer. It was exciting. On the first generation PC one had to toggle in a paper tape loader from front panel switches, byte by byte, then start the paper tape reader and then one could output to the led on the front…
At the beginning of this decade (2010), a few of us Haskellers were exploring how best to do client-side web programming. We didn’t want to write JavaScript. There’s a surprising number of techniques we tried to avoid doing so. There was work coming from academia and industry. Here’s a history of my own experience in…
Check out a cool project that leverages Stack Overflow Data and Google's Cloud AI to predict what tags would work best on Stack Overflow questions.
The Personal blog and musings of Chris Penner, a designer, developer and future opsimath.
Today, we are excited to open several repos on GitHub, and invite everybody to join us on GitHub.
We've put together an index of testing terms and articles, covering many of the basics of testing and definitions for common searches.
We explain how C array sizes become part of the binary interface of a library and examine ways to avoid ABI compatibility issues.
The first task of last week's Weekly Challenge was to print the first ten strong and weak primes. A prime p n is "strong" if it's larger than the average of its two neighbouring primes ( i.e. p n > (p n-1 +p n+1 )/2 ). A prime is "weak" if it's smaller than the average of its two neighbours.
There is a misconception that Lisp is a dynamically typed language and doesn’t offer compile-time type checking. Lisp being the…
How learning the Clojure programming language three years ago changed my life
A new major version of Bazel, Bazel 2.0 has just been released. In particular, it brings some important flag flips that did not make it into Bazel 1.0 .
You’re making morning drip coffee. You need to make 2 cups. Do you:
I hear more voices saying [https://hackernoon.com/the-myth-of-software-time-estimations-576a7466d91a] there is little point in doing time-based estimations on how long building software will take, and thus we should just stop doing it. "Let's just use story points and estimate complexity, but not
CUDA grep : Manish and Brandon's 15418 final project
This is the inaugural issue of Cryptography Dispatches, meant to be quick, frequent and lightly edited discussions of cryptographic topics. Longer form can be found at blog.filippo.io. If you are not reading this in your email client, you can subscribe here .
Evaluating Rust as the common denominator of modern development
Sandspiel is a falling sand game I built in late 2018. I really enjoyed writing this game, and wanted to put into writing some of my goals, design decisions, and learnings from that process. If you’re reading this but haven’t played sandspiel, you should probably go try it !
Kubernetes has changed the way I operate software. Whole classes of production problems have disappeared–arguably to be replaced by others. But such is the way of the world. All told I’m happier operating a microservices app today than I was before I started using Kubernetes.
A guide for wrapping Go code in Swift for use within a native macOS or iOS application.
A few days back I read an article about how Bitcoin’s price can be sufficiently explained by Metcalfe’s law. As you read through the post, resist the temptation to click the links to learn more about Bitcoin, Metcalfe’s law etc. (Maybe you should read about Bitcoin if you have not heard of it). I have provided all the…
SAT is often described as the "mother of all NP-complete problems." This post goes over what SAT is and why it is considered to be so important. A simple SAT solver is implemented using Python in the process.
