Sword of Damocles free #knitting pattern by Grace Lindley. This knit tapestry is brilliant. If you ever felt your #WIPs or to-do list were hanging over you like the Sword of Damocles, you can manifest it by knitting this double knit work of art.

Finally made it to the @connections and woah, there’s a lot happening in there - tons of things to see and noise! Had a lovely tour through their aisles and aisles worth of equipment, and got to say hi to a few of the volunteers there too - we could have spent hours there omg ​:trans_nya:

Interesting regarding the scoping. I’ve lived in Germany for over a decade though still have a UK Apple ID for purchases so assumed I’d be out, but it sounds like that may not be the case.

New blog post: An update about my Rust implementation of Galileo OSNMA. OSNMA is a protocol, currently in test, used to authenticate cryptographically the data in the Galileo EU GNSS. Two years ago I published a Rust implementation of this protocol.

in reply to Daniel Estévez

In December 2023 there was a public key revocation exercise as part of the system tests. I have recorded and published the data, and report on what happened and how my software processes the scenario correctly.
in reply to Daniel Estévez loic_fejoz reshared this.

Finally, I give an overview of the state of open-source OSNMA implementations. All other implementations I've found are in Python (not suitable for embedded microcontrollers) and under a copyleft license (or no license). So my galileo-osnma implementation in Rust with MIT + Apache license still occupies a singular position.

in reply to isithran

This looks pretty good, although I haven't quite yet figured out how it works.

I used to use Video Analyzer to explain video codecs to students, but it's unmaintained for 7 years, it also doesn't let you load just any video (needs a h265 yuv stream)
https://github.com/gabrieldiego/VideoAnalyzer

I found it slightly easier to get to the parts I want to explain (blocks, motion vectors), maybe it's also interesting to you.

You can see me using it here starting at 15:40 https://docs.claudiuscoenen.de/2022-WS-G1C/docs/2023-02-03-Video/#videocodec (german, sorry)

TIFO the Arduino Ethernet library performs unbuffered byte-by-byte transfers when you're using print() and println(), leading to unreasonably increased turnaround count. I'll need to dig in the library's code, to check why, and I'll probably make a bug report.

This doesn't happen when using write() with an explicit buffer length, though.

PCAP: https://app.packetsafari.com/analyze/l/KllD-YoBW6-oT3TQMCLj
"2 text/gemini\r" is written using println(), and the page content with write( void*, size_t).

in reply to isithran

Ok, apparently, print and println are inherited by the stream class, which explains why the write is unbuffered. Next, I'll need to check if I can do a zero-copy write() from flash, otherwise, I'll do a buffered write().

OH MY FUCKING GOD.

Pictured: Apple's M2 MacBook Air 13" speaker response (measured with a mic), and the response you get when you zero out every 128th sample of a sine sweep.

They have a stupid off-by-one bug in the middle of their bass enhancer AND NOBODY NOTICED NOR FIXED IT IN OVER A YEAR.

So instead of this (for a 128-sample block size):

for (int sample = 0; sample <= 127; sample++)<br>    // process sample<br>

They did this:
for (int sample = 0; sample < 127; sample++)<br>    // process sample<br>

Legendary audio engineering there Apple.

We can now, very confidently say the audio quality of Asahi Linux will be better than Apple's. Because we don't have blatant, in your face off-by-one bugs in our DSP and we actually check the output to make sure it's good 😂​

FFS, and people praise them for audio quality. I get it, the bar is so low it's buried underground for just about every other laptop, but come on...

Edit: replaced gif with video because Mastodon is choking on the animation duration...

Edit 2: Update below; I can repro this across a large range of versions on this machine but none of the other models I've tried so far. It is definitely a bug, very very obvious to the ear, and seems unique to this machine model.

Edit 3: Still there in Sonoma, this is a current bug.
