Today I announce a new project: Swig . Swig is a monolithic, multithreaded, micro web framework designed for an air-gapped intranet environment. Aside from Python 3, it has zero dependencies; just download and deploy. Out of the box, Swig supports IPv4 and IPv6, HTTP and HTTPS, block and chunked responses, and gzip compression. I encourage you to go through the README for more information, and to check out the code on GitHub repo . P..

Last night I moved this site from a VM in the UK to a static deployment in Google Cloud Run . It’s a neat service that can take a pre-packaged container and route HTTP and gRPC requests to that container. The concept of having immutable versions of infrastructure deployed, such that it’s clear what the deltas between versions were, and rollback is clearly nothing new, but it’s really nice that it’s quite so easy to deploy things on GCP thi..

KVM is a virtualization technology that comes with the Linux kernel. In other words, it allows you to run multiple virtual machines (VMs) on a single Linux VM host. VMs in this case are known as guests. If you ever used QEMU or VirtualBox on Linux - you know what KVM is capable of. But how does it work under the hood? ioctl KVM provides an API via a special device node - /dev/kvm.

This post is meant to be a counterpart to the previous KVM post, but about containers instead. The idea is to show how exactly containers work by running a busybox Docker image in our own small container runner. Unlike a VM, container is very vague term. Normally, we call containers a self-contained bundle of code and its dependencies, that can be shipped together and run in an isolated environment inside some host operating system.

Previously in database basics: 1. SELECT, INSERT, CREATE and a REPL 2. binary expressions and WHERE filters 3. indexes In this post, we'll extend gosql to implement the database/sql driver interface. This will allow us to interact with gosql the same way we would interact with any other database. Here is an example familiar program (stored in cmd/sqlexample/main.go) we'll be able to run: package main import....

Conventional wisdom dictates that the larger the number of types declared in a Go program, the larger the resulting binary. Intuitively this makes sense, after all, what’s the point in defining a bunch of types if you’re not going to write code that operates on them. However, part of the job of a linker is […]

I’ve been building a compiler for a small lambda calculus that compiles to x86. It’s pretty broken, and I decided to start from scratch. I checked out a new branch in Git, and then deleted the entirety of my compiler before I had a chance to do anything else. It hurt. But it was a good kind of hurt. I don’t usually just blow everything away like that. Even this time, I’m keeping many of my auxiliary functions. I’m not rewriting the ....

We're used, as software engineers to try to make things perfect, to see things from above, to think we're great architects and creators. What's more important though is to create software that does an important job for someone. What are the best ways to create such software?

Docker is a common tool for Python developers creating and deploying applications, but what do you need to know if you want to use Docker for data science and machine learning? What are the best practices if you want to start using containers for your scientific projects? This week we have Tania Allard on the show. She is a Sr. Developer Advocate at Microsoft focusing on Machine Learning, scientific computing, research and open source.

If you looked at First Crack’s internal commit history, you would see that most features take at most a few days to write. Even the entirety of First Crack’s rewrite happened over the course of a couple weeks, in the mornings before work and on the weekends. I have stuck with monthly releases since June of last year , though, and today I want to explain why. Permalink.

Note 1 : The term Rustacean is the term for a developer who uses Rust . Learning a new language isn't just syntax and keywords, it is tooling, people in the ecosystem to trust and follow, workflows and more. For a particular project at my day job, I've hit the limits of Python and Ruby in terms of performance so I'm looking into Rust (the other suggested alternative is Elixir and that's tempting but Rust "feels" like a better match). ....
