I used the "FX" option and I think there's a bug. The center tiles on each side always stay in the same position.

I like the "challenges" part at the end, especially the varying difficulty levels: * A quadratic formula program, which outputs the number of roots and the x-intercepts upon the user inputting the values of A, B, and C. * A fighti

Only tangentially related (but hey, it's HN) - I'm so happy about the support/requirements for trailing commas in the modern language syntax: x = [ 123, 456, 789, ]; It makes editing such a list

The article doesn't mention the recent development in Amiga extension cards - PiStorm is an easy (and affordable) way to max out the specs of any Amiga, A600 included.

I've always seen A600 more like a budget version of A1200 rather than a new variant of A500: better graphics chip, IDE port, PCMCIA and new look-and-feel of the Workbench 2.04 (at the first sight hardly distinguishable from the Workben

12 years ago, when we already had Arduino but no ESP32 yet, I built this thing: https://newton-net-pl.translate.goog/2012/01/robot/?_x_tr_sl... It was made of an old HTC Magic phone, acting as camera+wifi tra

Yes, the liar have some hats. There are two ways how to conclude this: 1. If they don't have any hats, then any sentence about them would be truth. 2. The negation of the sentence, which must be truth, is "not all my hats are gree

I love the slow pace of the video, including a few minutes presentation of all available programs. And indeed, there are programs to test dice and coin bias: * https://youtu.be/bJiOia5PoGE?si=IEhbNJk0C0-7_2Nj&t=229 * h

We can also assume that the p/q=√2 is already the simplest form of the fraction, since every fraction must have one, as in the first section of the article. Then if we figure out that both p and q are even, it means that p/q can b

A few years ago, I spent a fair share of time trying to copy files from and to a Macintosh Plus. I decided to use a 100 MB ZIP drive (actually two of them, SCSI for the Mac Plus and USB for a modern computer) and later a serial port connect

This is similar to Kotlin single-expression functions, which are actually pretty useful: fun double(x: Int) = x * 2 https://kotlinlang.org/docs/functions.html#single-expression... However, in Kotlin there&#x27

The results are correct, but the explanation is wrong, e.g.: By using our Celsius to Fahrenheit conversion tool, you know that one Celsius is equivalent to 33.8 1000 C = 1000 x 33.8 = 1832 F Probably the explanation engine does

Procedural generation was also used to generate levels in the Pitfall game for Atari 2600. A single level was represented with a byte (!) and bits were controlling the number of rolling logs, holes, etc. There were 255 levels there and LFSR

This approach is very similar to the way how Kubernetes custom resource reconciliation works (and Kubernetes in general, but the custom resources is the way how you can bring your own logic there). In Kubernetes you can define your own type
