You will not be going to Memphis today

If you understood this post: Congratulations

UPDATE: Wait Dual Kevin switched from Rashid! There is still the opportunity to go to Memphis

UPDATE 2: WE WENT TO MEMPHIS??!

@mcc@mastodon.social avatar

In the end, we went to like… Oaxaca or something? But the road there lead through Memphis

🐈 play junkoid for nintendo now, it's a romhack of metroid where you can play as a women, something never seen before in video games. patched rom download here >>> https://sylvie.website/Junkoid.nes

A girl in an environment of pipes and rocks and water and there's like a crawly thing.

@lovegame Oh… I get it… is her name Junko

A thing that is really fun with fighting game tournaments as well as speedrunning events is how the commentators will get really inconsistent with pronouns, like do you refer to a player by their own pronouns or by the pronouns of the character they're playing. Could go either way. Identity becomes fluid with performance

In 2014, Steve Wozniak woke up in the middle of the night and suddenly thought of a possible improvement on the Apple // design he had until that moment entirely missed https://groups.google.com/g/comp.sys.apple2/c/iiLgD-7INtE

His 2014 modification to the Apple // design would have reduced the production cost of the machine while also adding an additional color to the LORES mode (this mode has 16 colors but colors 5 and 10 are identical shades of gray so on the shipping device it's really only 15; Woz's 2014 change would have made them lighter and darker shades of gray, bringing it up to a true 16 colors). Somebody tested it and it seems to work

@foone I have encountered Steve Wozniak IRL… I was at NASA* and Steve Wozniak zoomed by on a Segway

  • Used to be a yearly concert event at NASA Ames on the anniversary of the Yuri Gagarin flight

@foone I did not get a chance to talk to him or anything. Steve Wozniak was too fast for me

It's really difficult to search search engines for information about the Apple 1 and Apple 2 due to the ambiguous and symbol-heavy naming of Apple 2 vs Apple II vs Apple //

mcc,
@mcc@mastodon.social avatar

@Cdespinosa I'm thinking of the thing that you could make happen on an Apple // where you crash so hard it would just print columns of hexadecimal numbers from memory. I've recently been told (for example the The 8-Bit Guy video on the Apple I on YouTube) that was called "Wozmon" and that it was reused from the Apple I where it served as a kind of bootloader (or maybe a bootloader loader, as you'd type in the bootloader program as hex).

mcc,
@mcc@mastodon.social avatar

@Cdespinosa Now that I double check, I cannot right now find any sources verifying the Apple I hexadecimal-columns mode and the Apple II hexadecimal-columns mode were literally the same program, so maybe I jumped to a conclusion there! But there is some very Wozmon-like memory debugger in the Apple II ROM, I've triggered it…

mcc,
@mcc@mastodon.social avatar

@avidrissman @Cdespinosa I guess one question is whether "Wozmon" was ever an official name or if this was just a community name for Wozniak's monitor.

mcc, (edited )
@mcc@mastodon.social avatar

@Cdespinosa That's very interesting, thank you!

How similar was the command syntax in the 1 and 2 monitors? I've been wondering about this…

In my experience, it was a "common uncommon" experience for Apple // software to drop into the monitor program when things got messed up. But I guess that might have been something the program was doing internally (detect a crash condition and poke the monitor awake)…

mcc,
@mcc@mastodon.social avatar

@Cdespinosa Cassette tape operations in the memory debugger! That's hardcore!

When your computer crashes the blue screen still works. Why not make the whole computer out of blue screen?

mcc,

@SteveSyfuhs @pb @anildash Would it be, in principle, possible (for example by plugging in the correct debugger) to configure a Windows machine just stay inside the mini-kernel and drop you into an in-kernel debugger interface?

Heeeck I dunno if I'll be able to test it before the stream but I think I just got .xm/mod tracker file playback working on the Analogue Pocket

Screenshot is highly significant to me but it is complicated to explain why this is proof I can run it on the Pocket

mcc,
@mcc@mastodon.social avatar

The code ran on the pocket but it's only playing out heavy static :( I dunno if the problem is in my code, the .xm player code, the CPU (it's an FPGA softcore) or my port of the .xm player to no_std :(

Gonna be depressing if I spend all that time porting this library to no_std and it turns out to be too slow to run on my target machine :(

mcc,
@mcc@mastodon.social avatar

The library's using, like, floats for the audio samples. That's weird to me. The format it plays was created for FastTracker 2. Surely FastTracker 2 ran on non-FPU machines. (We have an FPU on the Pocket softcore, but I don't know how good it is. I've been avoiding using it until now.)

mcc,
@mcc@mastodon.social avatar

Okay progress! I guess! I have upgraded from structured white noise to some REALLY WEIRD chirpy hissing. Gonna try to record some and post it later. May have accidentally found an entirely novel audio glitching method

mcc,
@mcc@mastodon.social avatar

@maks No, you're right, and any modern program integrating a xm player is most likely to be more easily able to ingest floats than shorts.

mcc,
@mcc@mastodon.social avatar

@maks The Analogue Pocket has no CPU at all (other than a small PIC chip which is used only for bootloading and could probably be removed in a future revision, as there is no direct access to it). I am using agg23's riscv core, which packages the open source LiteX and "vexriscv" projects and exposes a framebuffer plus registers for accessing Pocket features like audio and the sd card.

mcc,
@mcc@mastodon.social avatar

@maks This puts me in the unusual scenario that I could potentially solve my speed problems by adding a second CPU core. I think we actually have spare space on the FPGA for several.

My use of the word "softcore" was meant to refer to a CPU that doesn't "exist" but is running on an FPGA as gateware.

Over on twitter there has been a bit of a back and forth on C# and Rust simple json server performance.

I know C# has gotten a ton of performance tuning on the stack, and was wondering if Swift was up to the task.

I have never done Swift on the Server before, but the results are impressive:

Swift: 64k req/sec
.NET: 61k req/sec

@Migueldeicaza That seems really strange! Is that strange?
