wwarren··on LÖVE: 2D Game Framework for Lua
I love LÖVE. For me it sits at the perfect intersection between high and low level abstraction. Unfortunately the latest released version is getting pretty long in the tooth now and a lot of devs use the latest HEAD from the repo since it has better performance and compatibility. One day the mythical 12.0 will get released for real…..

Nice idea!!

Following the RSS feed is probably the best way for now!

YES, a modern version of the 74181 is equivalent to about 12-20 chips in the LS or HC series. It would be so useful. Someone should do a tiny tapeout!

This is such a nice comment! Thanks for reading :)

Dread was the desired outcome haha. I was also kind of excited to prove to others that you can have fast clock speeds without spending forever bending and stripping wires (for my fellow lazy/busy people).

Honestly even though it is a bit of a rats nest, in my mind it feels like a kind of organized chaos. And easy to trace any single route.

For the microcode ROMs they can just be “hardwired” with a zillion simpler gates. This has the added benefit of supporting way higher clock speed. For my planned program ROM you would either have to input manually like the first computers, or use other things like punch cards or your computer would be again “hardwired” to load programs from some other media

Type 2 fun, totally stealing that!

You can do so much before needing to buy anything or even learn any electronics. There’s a lot of good simulation options out there like Digital, Logisim-Evolution, even video games like Turing Complete and Logic World! That’s before you even get into stuff like Verilog. Thanks for the kind words!

Gotta use what you’ve got! Thanks for recognizing the madness :)

For iPad maybe try Delta emulator and the NES version of Tetris
wwarren··on Animals Made from 13 Circles (2016)
It’s mentioned in the article under the images as the inspiration for this work
wwarren··on Taking a $15 Casio F91W 5km underwater
The circle is complete
wwarren··on Build a Database in 3000 Lines with 0 Dependencies
Check the reviews online, but generally random bits of Go code are presented with no build-up or explanation. B Trees are implemented immediately and without explanation. The book is incredibly short and seems just like a loose collection of notes, rather than an actual book. Very interested to check out the new version

Man I got the first edition of this book and it was so bad. Hopefully this is better…
wwarren··on True Crime: Allan Pinkerton's Thirty Years a Detective (1884)
The player character in Bioshock Infinite is a disgraced former Pinkerton. Great game

(2016)?

Let's see Paul Allen's Turing machine
wwarren··on Arc Will Change the Way You Work on the Web
Been using it for months for work and play and haven't looked back. It prevents accumulating tabs infinitely, and has a number of quality of life improvements that I now can't live without
wwarren··on UTM running Windows 10 on an M1 iPad Pro (virtualized at full speed)
Is this the arm version of windows?
wwarren··on Apple May Be Working on RealityOS
Probably an OS for an upcoming piece of VR hardware, if I had to guess https://www.inc.com/jason-aten/3-reasons-why-apples-upcoming...
wwarren··on Show HN: A low power 1U Raspberry Pi cluster server for inexpensive colocation
I think the Pi 4 and above don't have that issue any more? I could be wrong

Yep talk to your GP and they should be able to refer you (or they might feel comfortable assessing/prescribing without doing a referral).
wwarren··on DigitalOcean S-1
In my experience this is 100% the case with all IaaS providers. AWS's entire IP space is basically on all email block lists for example.
