bear8642··on Plan 9 from Bell Labs in Cyberspace
Indeed - there was post recently about port to Lua which want to investigate further
bear8642··on Tail Call Optimization: The Musical (2019) [video]
Thought there's extension enabling JVM tail optimization?
bear8642··on An S-100 80486 CPU Board
Appears the 80486 can be connected to the S100 bus directly given ability to read from adjustable size databus.

This means effectively an x86 style cpu can be part of a simple computer design

bear8642··on The Future of Group Messaging
Excellent ideas

>connect a message back to the parent message - if it was a response

Assuming you've got a long list of timestamped messages, how do you identify which messages are continuations of old threads and which ones are starting a new conversation?

bear8642··on Fast character case conversion, or how to really compress sparse arrays
Nice! Bit confused on link to TSP but cool!
bear8642··on A one-bit processor explained: reverse-engineering the vintage MC14500B
even more extreme are ZISC: https://en.m.wikipedia.org/wiki/No_instruction_set_computing
bear8642··on A one-bit processor explained: reverse-engineering the vintage MC14500B
>a 1-bit processor isn't very exciting

Very different order of magnitude but wasn't the connection machine single bit based?

bear8642··on The Elements of Computing Systems, Second Edition
Sounds like you had an excellent romp = was scheme taught with SICP?

Lambda calculus' anonymous functions are fairly simple but massively powerful - try this page? <https://www.inf.fu-berlin.de/lehre/WS03/alpi/lambda.pdf>

bear8642··on The APL Orchard
To confirm, that Stack Exchange?
bear8642··on Why Are So Many Romances Set in the Regency Period?
>"high" vs "low" fantasy

Thought distinction (originally at least) was whether fantasy happening on imagined realm or here on Earth?

bear8642··on How to write cuneiform
He taught Tom Scott too: https://www.youtube.com/watch?v=zOwP0KUlnZg

Found best line was to remember cuneiform is strokes into something soft, not ink as we do now

bear8642··on J one-page interpreter fragment (1992)
Indeed - was confused what elements of struct were on line 2.

Thanks for explaining

bear8642··on The computer revolution hasn’t happened yet (1997)
Can't tell if you're being earnest or funny. Care to say why?
bear8642··on Software engineering topics I changed my mind on
>rather than a notebook

Enjoyed these notepads (http://www.computinghistory.org.uk/det/46261/Floppy-Disk-Not...) for quick scribbles.

More substantial then post-its yet pages easy pull out

bear8642··on Software engineering topics I changed my mind on
>test first it wouldn't have been half as dodgy.

Feel part of this, in my very little experience, is with tests focus is getting smallest thing working so less to go wrong

bear8642··on 27th International Obfuscated C Code Contest winners published
odd Windows gave you that - believe \r was Mac's standard at one point…
bear8642··on The Birth of Unix with Brian Kernighan
Indeed! Their book Elements Of Programming Style is also a fun short read
bear8642··on Books for Programmers
Found Kernighan and Plauger's Elements of Programming Style useful - interesting to see how many of their comments on Fortran and PL/I code still remain very valid problems.

Their further book Software Tools in Pascal I found inspiring (along with SICP) as they show how you can build very powerful and useful tools from small modules slotted together - SICP showed me this in the extreme with chapter 2 ending with an implementation of a full numeric tower

bear8642··on Books for Programmers
for the Nand2Tetris course
bear8642··on Ask HN: What are some of your favorite journals or magazines?
Second New Statesman always fascinating perspectives on current affairs
bear8642··on An Intuition for Lisp Syntax
>I'm not sure who GJS is…

Gerald Jay Sussman

bear8642··on Chibicc: A Small C Compiler
My immediate thought given title
bear8642··on Big O, Little N
Thanks for this - very interesting small article
bear8642··on Ask HN: You've got $300 to fill an empty library. What do you choose?
Second hand bookshops are amazing things - sometimes goldmines can be found!
bear8642··on A Field Guide to Genetic Programming (2008) [pdf]
Would you mind explaining why it didn't take off?

Imagine problem of domain but something definite would be nice as having trouble finding anything

Thanks

bear8642··on Non-Posix File Systems
Indeed and that's what Plan9 enables you to do
bear8642··on Ask HN: As a developer what are your aha moments?
>Working through the nand2tetris project

Done various sections of this and would heartily agree with how illuminating working through the project's been

bear8642··on Epigrams on Programming (1982)
would you care to elaborate on which ones are which?
bear8642··on A gentle introduction to pointers using C (2019)
And that's the way they're shown in K&R2
bear8642··on Robpike/Lisp: Toy Lisp 1.5 interpreter in Go
Whilst Pike contributed to Unix it was Thompson's and Ritchie's invention - at least originally
