<p>A webhooks allow two applications to communicate events. It is relatively simple to get started using webhooks using HTTP and JSON. However, there a number of failure scenarios that developers should be aware of in order to make their webhook implementation robust.</p>
If you’re thinking of migrating to another infrastructure as code tool (and why would you, everything is great in the IaC world now, right?!) you might find yourself asking yourself

It’s believed that many of us spend seven hours or more in front of screens each day. In 2011, researcher Emmanuel Stamatakis, found that “…even those who exercise can’t overcome the detrimental ef…
Technician: Welcome to Custom Lube, how can I help you? Me: I need an oil change. Technician: OK, you can hop on out. Where is the oil you want to use? Me: I didn’t bring any oil. I expected you would supply that. Technician: That’s a common misunderstanding. At Custom Lube, we don’t supply oil or anything else. We…
Our last blog post on Linux mount namespaces explored ways to restrict access to the file system. In this post we'll show how to restrict access to the network.
I guess this is a review of sorts, so here's the review part: you should buy Tech by Androda's new 7MB Macintosh Portable RAM card . On my D...
Has nerd sniping gone too far?
Viktor Lofgren is the creator of Marginalia Search , a search engine takes you of the beaten track by letting you find small quality web pages. These pages barely surface in commercial search engines because they are snowed under by larger commercial websites and marketing. We interviewed Viktor for FreeWebSearchDay …
Over the past two years, I have spent a lot of time working on my Game Boy emulator, GameRoy. It has reached a good point, where it has a GUI interface (including a debugger and disassembler) and passes numerous tests (comparable to some of the most accurate emulators). I even made a port to Android!
As far as I know this is the first Haskell program compiled to Webassembly (WASM) with mainline ghc and using the browser DOM.
A visual example-focused introduction to neural networks.
Requests for Comments (RFCs) are how we specify many protocols on the Internet. These documents are alternatively treated as holy texts by developers who parse them for hidden meanings, then shunned as irrelevant because they can’t be understood. This often leads to frustration and – more significantly …
MIT physicists captured the first images that directly show the pairing of fermions. The snapshots of particles pairing up in a cloud of atoms can provide clues to how electrons pair up in a superconducting material.
The Go Execution Tracer (aka runtime/trace) was designed to achieve low enough overhead to be usable on “a server in production serving live traffic”. This is achieved by writing events into per-P buffers, using RDTSC for timestamps, and encoding into a relatively efficient binary format.
It's not about technology for its own sake. It's about being able to implement your ideas.
