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.
Amiga 2000 - codename Tesseract - the first part of a series of posts about building an Amiga 2000 from scratch and adding mods to it.
In a previous post, I used a simple interpreter bug to demonstrate the research skill of manually reducing test cases. This time, I show off the excellent Shrinkray reducer to see how it can automate the same process. The tricky part when using automated test-case reducers is writing an interestingness test that…
Picture this: It’s ten years ago, and you’ve just launched a new WordPress blog. Within hours, sometimes even minutes, your content is indexed by Google. You search for a unique sentence from your…
Their creator has disavowed them. The measure and definition is different for every team that uses it. They sow confusion, create conflict, unreliable
At least a dozen organizations with domain names at domain registrar Squarespace saw their websites hijacked last week. Squarespace bought all assets of Google Domains a year ago, but many customers still haven’t set up their new accounts. Experts say malicious hackers learned they could commandeer any migrated…
Just like CAD didn't make everyone an industrial designer, visual programming isn't going to make everyone a programmer. Whether textual or visual, there'd still be a lot of underlying concepts (and how they are composed) to learn. But still, I think it's underexplored. Most visual programming paradigms focus on…
strlcpy(3) is an OpenBSD function which is often hailed as a safer replacement for strcpy(3) and/or strncpy(3) . One of the obvious issues with strlcpy is that it's not safe if src isn't null-terminated. However, that's not the reason I don't like strlcpy. In fact despite knowing this, I used to think it was an okay…
