This may be that I'm living under a rock, but I've found out recently there is an initiative to test DIY HRT sources 🔗HRT Source Testing

HRT Source Testing — Trans Harm Reduction

Trans harm reduction has recently begun testing HRT sources which are commonly used by trans people who are self-medicating. This involves testing a vial of HRT for concentration (strength) and testing for contamination (impurities).

Understanding Apple’s Response to the DMA

What a week. When it began to look like Apple would announce how it planned to comply with the EU’s Digital Markets Act (DMA), I expected small changes at the margins that wouldn’t significantly move the needle in the EU or anywhere else.

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.

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).

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.

edit:
Not fine broken too!
I first used 300 HZ like in your text.
If I use the 270 Hz like you did in the video it’s very noticeable distorted too.
:-(

plays fine on my M2 MacBook Air 13“ with Sonoma 14.0
Found the very same website tone generator you used.
MBAir plays the same like iPad and not as distorted like in your video - maybe it is an “not all Models” Problem if some hw parts?

Edit:#2
Use 270 HZ not 300 Hz to test.
