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 us…

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 editi…

Not a tutorial per-se, but here are 2 slides describing how I've done it: https://www.slideshare.net/slideshow/emulating-game-boy-in-j... Essentially, there are 4 channels, each pr…

Famous example from the pop-culture is Burr vs Hamilton: > If you stand for nothing, Burr, what'll you fall for?

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 …

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 phon…

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,…

Programming a chess program was an important challenge for the "first generation of hackers" working on the mainframe machines like TX-0 and PDP-1 in '50 and '60, as described in "…

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/bJi…

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 t…

Similar, but in Haskell: https://github.com/DataKinds/sixty-five-oh-two It's a DSL for writing 6502 assembly.

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 an…

And if you have even older Mac (128/512/Plus) and want to use an almost modern PS/2 keyboard with it, please check my https://github.com/trekawek/mac-plus-ps2

Same with Dell P3223QE.

I remember having similar effects after long sessions of Lemmings. I saw the damn rodents when I was closing my eyes in bed, but it didn’t disturb my sleep (I guess they acted as s…

Trivia: this one was created by Adrian Zandberg, currently a Polish MP.

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... …

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.…

Hey, SBC: result = byte1 - byte2 - carry carry = result 0xff return result & 0xff Source - my implementation, passes tests. Look for SBC & ADC in https://github.com/trekawek/coffee…

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 ro…
