The web platform is the delivery mechanism of choice for a ton of software these days, either through the web browser itself or through Electron, but that doesn’t mean there isn’t a place for a good old fashioned straight-up desktop application in the picture.
It's a C test. If you think you know C, take this test. It only has 5 questions.
This issue came up recently for a high profile new gadget that has made the transition from Micro-USB to USB-C in its latest version, the…
After a rather long break from programming and Clojure I decided give them another go. When it comes to managing Clojure projects, Leiningen is de-facto standard tool. Recently, Clojure CLI tools are becoming more and more popular, though. Switching to yet-another-build-tool doesn't have any pragmatic value, but it's…
Updated (2023-05-08): the Go compiler keeps evolving and it takes time to keep up with changes. While the general gist of this post remains true and it's worth reading to understand how the compiler works on a high level, the details of the modifications are slightly different now.
I’ve had Elixir on the brain recently. And by recently I probably mean 2 years. In my defense I think it is fair to say it is blooming right now. I haven’t had much need of it, or opportunity for it, in my day-to-day of maintaining a Python legacy system, renewing another legacy or optimizing Elasticsearch. So I’ve…
This article shows how to construct a non-recursive zip bomb that achieves a high compression ratio by overlapping files inside the zip container. "Non-recursive" means that it does not rely on a decompressor's recursively unpacking zip files nested within zip files: it expands fully after a single round of…
Not every code injection bug is a security hole.
GitLab will be ending support for MySQL starting with our 12.1 release – here's why.
I had a student (Fred Smith) who worked on extensions to Popcorn (the predecessor to Cyclone) that supported run-time code generation in a lightweight fashion. Here’s a paper describing part of the system: https://ecommons.cornell.edu/handle/1813/5812 . Fred’s thesis had a bunch more.
I first heard about Svelte a year ago, when Rich Harris presented it at JSConf EU 2018. The demo gods were a bit harsh on him, but it didn't matter to me, because I was so impressed by his philosophy and ideas that I was already sold. I knew he'd work out the kinks, go through a few major versions, and Svelte would be…
Image differentiation in three languages
This blog post shows you how to use the HAProxy Data Plane API to manage your load balancer configuration dynamically using HTTP commands.
This is where I write about the stuff that I've been working on.
Good judgement is the result of experience ... Experience is the result of bad judgement. — Fred Brooks
Sircmpwn (the main developer behind the Sway Wayland compositor ) recently wrote a blog post about how he thinks Rust is not a good C replacement . I don’t know if he’d like the D programming language either, but it’s become a C replacement for me.
In this blog post, I will present one of the most interesting additions to the community 2019 version of SPARK: pointer support. One of the core…
One of the frequent challenges in C is that pointers are nothing but a memory address. A callee who is passed a pointer doesn’t truly know anything other than the type of object being pointed at, which says some things about alignment and how that pointer can be used… maybe. If it’s a pointer to void ( void * ) then…
Beginning of the month Apple announced SwiftUI at the WWDC 2019. A single “cross platform”, “declarative” framework used to build tvOS, macOS, watchOS and iOS UIs. SwiftWebUI is bringing that to the Web ✔️
Back in mid-90s before anyone I knew had an Internet connection, a few of us had modems and would use them to call bulletin board systems via the phone line. On these systems what to me seemed the main thing was discussions and chat. For the first time I could talk to other like-minded people, and just being able to…
The other day, being unable to find a suitable open-source text editor for cpmish , I sat down and wrote a simple vi-like editor. It took nine hours. I have it all on video.
Only dead fish go with the flow. As I promised in the last article, today we’re finally going to do a deep dive into the topic of scopes. This is what we’re going to learn today: We’re going to learn about scopes, why they are useful, and …
