👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into 12 main parts: Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The…
For most of the 20th century, AT&T was almost entirely responsible for building and operating America’s telephone infrastructure.
Last fall, under the aegis of Ham Radio Village , I was awarded a grant to take my one-day Tech class on the road. Ham Radio Village believes that more people in technical fields should have amateur radio licenses and that amateur radio is underrepresented in the hacker, STEM/STEAM, and maker communities. Currently…
Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an…
Practical tips that allow you to build an evolving architecture
Large language models (LLM) have been all the rage for quite some time now. Looking beyond the hype though, they have severe limitations: hallucinations, lack o
Bézier curves are widely used for defining vector graphics. They are basically polynomial parametric curves, but given in the Bernstein basis, which enables us to define the curve using control points. The first and last control point define the start and endpoint of the curves, the intermediate control points kind of…
Critics unanimously agree that it sucks , and some have accused the company of deliberate deception . Rabbit Inc. reportedly accepts returns, but customers are so eager to get rid of their R1s that even new-in-box units are selling for well below RRP ($200) on secondary markets.

A few days ago I had to replace the old IP camera I use to watch over my dogs and cats, and found out that IP cam technology changed a lot since I bought that old camera. IP cameras are now low-price and ubiquitous. I bought one of those generic models and installed it at my home, expecting to use the same software…
Learning math early guards you against numerous academic risks, opens all kinds of doors to career opportunities, and allows you to enter those doors earlier in life (which in turn allows you to accomplish more over the course of your career).
If you've used CSS, you know what a class name is. They're a very poor proxy for the web today. Let's stop using them.
Today I noticed via a tweet by @mitsuhiko that Mermaid Gantt diagrams are great for displaying distributed trace information like what you’d get from JaegerU...
DX @ HuggingFace: Scaling open source ML community 200% a year with No OKRs & No Meetings
Note: this is the first part of three articles about my experience building a 1980s Yugoslav 8-bit computer called the Galaksija. This part is mostly focused on the technical aspects of building this…
Can I make math operations run 100x faster on really, really big numbers?
In this article, I look inside a chip in the IBM 3274 Control Unit. 1 But before I discuss the chip, I need to give some background on main...
Over the past few months, I’ve noticed that an increasing number of replies to email that I’ve sent are “reactions”.
/imagine one day randomly finding yourself in a foreign country thousands of kilometres away from home. Your own country is suddenly at war, and all you have is a backpack hanging off your back. That’s a weird situation to be in. But you have to figure something out. So starting a fake delivery company sounds like the…
To me, a classic JRPG is pure mechanism, a kind of puzzle. Was there some way of getting the fun out of building such a mechanism—of solving that puzzle—, wrapping it with the minimal amount of functionality, the simplest thing that could possibly pass as a video game?
NSCopyObject is a very old Foundation function – pre-dating Mac OS X entirely; from the NeXT era – that was originally basically just memcpy , but now it’s complicated. A lot more complicated.
A new way to make games
In the previous two golden ages (1950s-1960s and the 1980s), our expectations outpaced the capabilities of the technology at the time, leading to disappointment. In contrast, the AI technology of the current golden age, which began in the mid-2010s, has consistently exceeded our expectations.
DME (distance measuring equipment) is an aircraft radio navigation system that is used to measure the distance between an aircraft and a DME station on ground. DME is often colocated with a VOR station, in which case the VOR provides the bearing information. DME works by measuring the two-way time of flight of pulse…
I bought a Surface Pro 4 in 2016. It has an Intel Core m3-6Y30 CPU and 4GB memory. The spec is not that impressive even compared to an average laptop released years earlier. On the other hand, the form factor is very attractive to me: at a very low price, you get a tablet with a beautiful HiDPI 2k screen, a pressure…
Web site content explains the modern view of entropy change and the dispersal of energy in a process (at a specific temperature). It has been selected for instructors in general and physical chemistry by Dr. Frank L. Lambert, Professor Emeritus (Chemistry) of Occidental College, Los Angeles.
I’ve never been good at playing football 1 . I started playing again last year and I have scored more own goals than goals for my team. Also, I support the RCD Espanyol 2 , which has spent last season in the second division and has miraculously ascended to the first division last week. And to be honest, I only watch…
4% of all the money in America flows through a few mafia-like health care conglomerates. The FTC just released a ground-breaking report on how they operate. And it is gearing up to sue.
