One of the things I’ve always wanted to do ever since I built RGBMatrixEmulator is have a live cluster of MLB LED scoreboards available on demand. Well, today’s the day! It’s pretty simple: Set up a Dockerfile Clone mlb-led-scoreboard Expose the RGBMatrixEmulator port, by default 8888 And you’re done! Of course, this procedure could be repeated for any project that uses hzeller’s rpi-rgb-led-matrix driver libary. I chose to depl....

Optimizing ESP32-S3 Performance: Why Smaller Code Can Ran Faster I’ve been tuning the performance of some code recently on an ESP32-S3 project, There was a slightly counter-intuitive result that might surprise some people: optimizing for code size produced faster runtime performance than optimizing for performance. There’s a full video here - but you can skim this post for most of the information. The Benchmark This is just some cod....

I've been a big fan of probabilistic filters such as Bloom , and (more so) Cuckoo filters for a while now. I've put them to great use in my personal projects, as well as in major data processing projects at work. They fall into a neat class of data structures that let you trade certainty for performance. They are wildly useful for membership checks without loading the entire set into memory in cases where occasional false positives are....

TL;DR: Allow attendees to politely decline the conference freebies. I’ve attended quite a few tech conferences in India over the years, both as a speaker/trainer and attendee. Conferences can improve execution, meritocratic selection panels, and the ratio of sponsored to overall talks. These are mentioned as part of overall feedback to the event. But one thing is rarely questioned. The “swag.” You know what I mean - the badge, brochure, sti..

Our company is going to a convention later this month, and they will have a booth with big TV screens showing statistics that update in real time. My job is to write the backend server that delivers the statistics. I read over the documents that the product people had written up about what was wanted, asked questions, got answers, and then turned the original two-line ticket into a three-page ticket that said what should be done and how.....

SaaS won. Piracy died. It’s not that you can’t pirate software today; there are still cracked versions of Office and Photoshop out there. But today’s best business software can’t be pirated. You can’t torrent Slack, pirate Salesforce, crack Notion to give you more features for free. “Hardware must be paid for, but software is something to share,” lamented a young Bill Gates in 1976, whose dreams of hiring 10 developers to build softwa....
