Hi, these are all very valid points! 1) It is actually a 16 colors gray scale signal. So I am looking into a simple but fast ADC that can make it digital. 2) Level shifting and voltage change may indeed be required. I was told the output voltage ranges between -3 to +7V. But I'm not sure if this was measured with the monitor connected! So I may have to measure myself. 3) I found an IC that is designed for video level shifting. I posted it ..

Salutations, I hope all of you are having an excellent day. I was reading the MDN documentation regarding Canvas, and when I got to the animations section, I came across something I already knew but was terrified to accept: It's all about Math. It actually makes sense because, if you think about it, many successful computer scientists are or were mathematicians at heart (e.g. Mr. Guido van Rossum has a master's degree in Mathematic....

In reply to Jan de Lange. Hi, your input is analog, but you will find that there is no major difference between analog and digital when the signal is monochrome. The Pico of course expects a signal that is either 0V or 3.3V, and your display signal probably doesn't fulfill these expectations. Instead, it might be....

Most companies building AI products today are stuck in the experimental phase, lacking the basic tooling and infrastructure needed to build reliable systems. It’s easy to spot once you know what to look for. Take the current trend of companies talking about load-balancing their AI operations across multiple providers. Sounds sophisticated, right? But it reveals something concerning about the state of AI engineering. Let me show you why.....

Designing great resolver functions in GraphQL is quite unintuitive. Giving consumers the ability to describe their desired response payload means it’s possible for consumers to access fields via surprising paths through the graph, and this is something that can and should influence how you write your resolvers on a field level. Say you’re building a kanban board app like Trello or Asana. A board consists of many different named columns, wh..

Beth was a committed vegetarian when we started dating, had been for years. I was several years in, too. And I had cut out dairy and eggs a couple of years earlier. Vegans were less common then. People asked me about it. I worried that my choice made them feel inconvenienced or judged. I looked for inoffensive explanations. I liked that being vegan required discipline. I needed more discipline in my life. Being vegan helped. This was t....

What goes into creating automated tests for your Python code? Should you focus on testing the individual code sections or on how the entire system runs? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder's Weekly articles and projects.

So you have Flipper in your ruby codebase for handling feature flags but… now you have used them and need a way to find them and help you pay down the tech debt of cleaning them up. Well good news, you can use AST Parsing to find all the instance. This simple parser walks all the Ruby code looking for calls to Flipper.enabled? and makes a list of the features flags used.

Quick post. My goal was, I thought, simple: Run a CLI tool which checks if a JSON document is valid for a JSON schema and returns the line numbers with error details So I head over to json-schema.org/tools and look for one. I try: ajv-cli ⛔ Doesn’t handle field type of date boon ❌ Doesn’t show line numbers Test-Json ❌ built in powershell cmdlet - Doesn’t handle if-then-else schemas or show line info check-jsonschema ❌ no line ..

Earlier this week, I launched a new blog titled Digital Seams , which covers topics like APIs, platforms, UX, and interaction design, plus the related human connections. I hope you check it out! I'm writing Digital Seams because I looked at a pile of blog drafts and saw the running theme. Even looking back through my personal blog, I can trace similar ideas when I wrote about business hours for web companies ; and the efficacy of sel....

This is the 7th episode of season four. I started this season in January of 2024. My intent was to document the process of writing a book. But even though this season is over a year long, there have only been 7 episodes, and that’s because I took a 9 month break. I want to talk more about what happened during that break, and how I was derailed from my plans, and how I recovered. The Four Disciplines of Execution [affiliate link] On ..

This should be something useful for Linux kernel explorers and eBPF nerds! Last year I released a tool called syscallargs that walked through the Linux /sys/kernel/debug/tracing/events/syscalls directory tree and allowed you to query and list available system calls in your current system from the command line. And it printed out syscall argument names and their datatypes, so it has helped me avoid opening man-pages (or web-pages) a..

This post is part of the GenAI Series. In my previous post, I introduced OpenAI’s image APIs and used them to create avatars. Today, I’m diving into another LLM service, ClaudeAI, which has gained traction for its speed and sharp analytical responses. I asked Claude to brainstorm ideas for my next blog post about itself. Among many fantastic suggestions, I chose Customer Behavior Analysis. Finding a suitable dataset on Kaggle was easy, but ....

Great things do not happen on the first try. Many musicians record 50+ songs to select the 12 best ones for their album release. The rest gets trashed. Similarly, many business owners have a graveyard of failed projects before they finally hit something succesful. Maybe it was having the right co-founder, or the right contact […]

Ready Player Mode , which began as a tiny media-viewing experiment , has now become my daily music player. Along the way, I moved from regular daily streaming to buying and playing music offline, relying on the odd streaming service exclusively for discovery. This setup's been working great so far. I get unrestricted playback (for life) with the occasional discovery session whenever I see fit. Setup Ready Player Mode runs in Emacs. You....
