With Multics i'm familiar enough, i meant unisys specifically.

Is it at all possible to get a peak into that world as a curious person?

Crazy to think that it's apparently acceptable to centralize the web like that.

Yup! I used to use FreeBSD on my thinkpad but as time went on that became less practical and I've been on Linux ever since. First arch and then void kinda filled the spot. void feels a bit like home.

Immutability is a central concept in functional programming.

Unfortunately I can't help with the classical picture, but in quantum physics it all comes out very nicely: You can interpret the Lagrangian as giving all possibilities to build a trajectory through spacetime. In the path integral form

That's true but it was little more than a portable rendering API, which was of course very useful for the PS2, but probably less interesting for the PC ports. So if you want to count that, you're right, it's not totally from

As for Rockstar North/DMA specifically: It was a bunch of nerds making games in Scotland. From having reverse engineered gta3 and vice city and therefore knowing the code of these games quite intimately, i can tell that even at that ti

Really cool! This is the sorta thing that, just yesterday, I wished existed. And it's already on the HN frontpage. It's hard to see the forest for the trees in many math books, a bird's eye view is a really valuable perspecti

That was a very approachable explanation. Makes a lot of sense. Essentially by encoding the program algebraically you can prove that it is invariant under the action of the semi-lattice. Very neat! Maybe lean is worth a look.

Session persistence is the key feature for me. All the rest I don't need because i simply open more windows. However multiple windows (or whatever you call them) were really useful when I bought a vt100 as a teenager and programmed on

Where is perl being used today? I imagine it has a diehard community, but it's not very publicly visible these days.

LISP had FEXPRs from the beginning though. Not identical to macros, but similar in spirit.

Parent was not talking about the origin though. Present day obsession with so called "race" is absolutely a US phenomenon. Classifying people as "caucasian" for instance always trips me up because it's something tha

I always joke that forth doesn't actually exist. The only forth code that seems to exist is forth implementations.

I hadn't connected it to the pidp-10 panel yet actually, my stuff is older than that. but eventually i would like to. the approach i went with was to put some of the peripherals on the linux side of things but have the controller logic

This is a good start: https://www.masswerk.at/minskytron/ The pdp-1 "demoscene" has been rather inactive for ~6 decades now :) Our hope is to breathe some new life into it.

In case you didn't see, the hackaday project page has two more links on the side, but currently information is a bit sparse, sorry. We're currently on a sprint to finish and polish the software distribution.

I have a bunch of KA10 verilog that worked on a DE10-nano in the past, but it's been quite a while and i think i have a bunch of uncommitted stuff lying around as well. The verilog is based on the original schematics and I successfully

There are some versions of MIDAS around on bitsavers but I have to admit i haven't really looked into them much yet. Gotta leave something to the community, right? (or so i tell myself...). Another thing is that not all PDP-1s were the

As one of those guys in the photo I really hope everyone will have a lot of fun with this :) The photos don't show it but you can also have your PiDP-1 in white instead of blue. It will come with both sets of front panels.

Unfortunately we don't seem to have the MCS8080 macros to assemble this in the original way. Hopefully they will turn up eventually

No, if you need fixed addresses i suppose a linker script would be the way to go? Or in this case you'd just serialize the data such that it doesn't contain any pointers in the first place.

Anecdote probably not. But i learned how a compiler works from it and reconstructed the B compiler based on it (found here: https://github.com/aap/b , warning: repo is messy, will clean up more soon hopefully).

It's an awkward way to reserve memory. The important detail here is that both compiler phases do this, and the way the programs are linked guarantees that the reserved region has the same address in both phases. Therefore an expression

As a german i hadn't heard of the wright brothers until my 20s. Otto Lilienthal is the name associated with the invention of airplanes here.
