As I have a dedicated room for my office in our house and work from home, my wife doesn’t always know when I’m in a meeting. To me the obvious technical solution here was to hook up a networked lightbulb and control it with a big illuminated button on my desk, changing it from blue … Continue reading Embedded Project: Lightbulb Controller →
Is GraphQL a tool that will make your life better or worse? TL;DR: as with any technology it depends on your situation and needs. There are real benefits for developer experience and solving many related problems with a cohesive architecture, but it’s not just a simple drop-in replacement for REST, HATEOAS or {g,t}RPC. GraphQL is … Continue reading A Balanced Look at GraphQL →
V8, the JS runtime underneath Chrome, Edge, Node, Deno, and Electron, got some useful improvements for developers. One is a new simple (single-pass SSA, CFG, IR builder) JIT for short-lived programs like command-line tools or serverless functions. Called Maglev. I’m very interested how it will stack up against AWS’s low-latency runtime (LLRT) that will be … Continue reading Updates in the JS…

These include tools like Webpack, Turbopack, esbuild, and rollup. If you ask them to produce a bundle they will do their…
If you’re using AWS CDK and Cognito, probably you want to have a test user account. I use one mainly for testing GraphQL queries and mutations in the AppSync console which requires you to provide a userpool username and password. Here it is, using an AWS CloudFormation Custom Resource:

Three weeks of the unprovoked invasion of Ukraine by Russia has demonstrated the essential cruelty and homicidal nature of the Russian military and civilian leadership. Having discovered that their political goal of occupying the country and installing a puppet leader friendly to Moscow was going to be harder than anticipated, they have settled for wholesale … Continue reading Another Attempted…
One of the silver linings of this terrible, unnecessary catastrophe is the fact that this ill-conceived invasion is the best documented in history. The dissemination of information about combat, forces, movements, official and unofficial statements, largely via Ukrainian telegram channels, is swift and unprecedented. Countries use their official twitter accounts to troll and mock belligerents. ……
Unlike many in the media and in the chattering classes, I have an acute need to keep up accurately with the “situation” going on between Russia and Ukraine, as my home is in Ukraine. I need to know if it’s safe to stay there or not, so I have been following developments closely. By which … Continue reading What’s Really Going on on the Ukrainian Border? →
