does anyone know of any courses/training to teach about “green coding” best practices and teaching that mindset etc.? #permacomputing #greencoding

@jonny This definitely bears repeating, identifying watermarks have been used for a long time to find the source of material, and is easier to use by the year.

Yellow dots from printers, intentional typos in documents, the metadata, and I'm sure I've seen people manage to embed visuals into movie files that immediately ID it without changing the image enough to notice.

I suppose one benefit of metadata watermarks is that they're more likely to be too lazy to use trickier techniques.

Also present in the metadata are NISO tags for document status indicating the "final published version" (VoR), and limits on what domains it should be present on. Elsevier scans for PDFs with this metadata, so good idea to strip it any time you're sharing a copy.

Bring back infrared ports on stuff. Renormalize beaming little packets of data all over the place.

Imagine meeting your friend, beaming them the textfile zine you've been putting together, them beaming you a uxn rom they've been hacking on.

Direct, intentional, peer-to-peer sharing. No crowded spectrum, no tracking, just line-of-sight goodness.

At one point people talked on the nesdev forums about a serial bootloader that used the second controller port, and I don't think anyone actually put one into a game? I found code for an implementation at https://web.archive.org/web/20120401200051/http://blargg.parodius.com/nes-code/bootloader/usage.html and made it so you can launch it by putting a code in at the title screen of Nova 1.

I also put put in a hex editor, also accessible via code, and put a bunch of useful routines in a fixed place, Commodore KERNAL style.

I doubt anyone will use any of this but it's neat

​ hi, im looking for anyone who has something with an ARM CPU in it from 2004-2012 or so, as i want to know which devices all have Jazelle implementations (and what they implement), as part of my Jazelle reverse-engineering effort

these CPUs can be found in a lot of devices, ranging from embedded things with an ARM9 (eg. something with an FX3, or a TI Nspire), to smartphones or tables from the era, with a Cortex-A8/A9

the info i need is 1. the exact CPU model (eg. "ARM926EJ-S" or "dualcore Cortex-A9"), 2. the 'CPU ID' code (from CP15 0,c0,c0,0), 3. the contents of the JIDR register (cp14,7,c0,c0,0) and 4. the JTAG IDCODE (if possible) (please reply in DM, or if you have questions about how to retrieve these)

thanks!

My squirrelsona lol. She looks just a lil bit different from this now, but I still like how this came out! 🖤

TIL about https://lichess.org/ , one of the world's most popular chess servers, run entirely on free software by a nonprofit, ad-free, supported by donations with a budget of ~$420K/year according to https://lichess.org/costs

They've been around since 2010.

As awesome as this is to see, imagine how many free/open nonprofit alternatives to Big Tech platforms would exist if, down to the municipal level, we decided to support them with funding & infrastructure.

Today I had my first Dog Poo + Wheelchair experience, and so PICK UP AFTER YOUR DOG OKAY.

It's not just people's shoes it might affect, when dog poo gets on wheelchair wheels it will probably end up on the disabled person's hands and sleeves too! PICK UP AFTER YOUR DOG.
