Ever heard of the "millennial pause"? ... it's both making me feel a bit old, and making me dig my heels in because starting audio on the first frame of video is incorrect and broken for technical reasons. 😂

One reason being that some pipelines / devices take any opportunity to sleep, and then take a moment to get going again - like bluetooth headphones... This leaves you missing the first ~500ms or doing the forward-backward dance to start the media again.

My oh my, a toy with that sort of precision is going to be expensive!

This is utterly wild... am I a little smooth-brained, or is this totally unrealistic?

• 200 Mbps compressed to under 1 Mbps
• Realtime, i.e: ~1ms latency or better
• Encode and transmit in <10mW (yes, including radio)
• Lossless
• High-entropy input

... if you succeed, just email them your solution - no mention of any reward or Nobel Prize nomination.

I've just got a new toy, with a USB-C wall wart, which just puts out 12v at all times (no startup or negotiation supported). 😬

I'm intrigued... what score do you get, and what input device did you use?

Apparently ~10 BPS is typical.

HELP!!

Panda, Hedgehog(?), Cow, Dog, Dog, Dog...

These all have brains, right? clicks skip.

Ohhh, it's not a hedgehog, it's a SOFA...?! 🤦‍♀️

... oh, damn.

Another variant of the image... the thing that still kind of looks like a hedgehog, might now be considered more sofa-esque.

Font size 710?... sounds reasonable.

Always makes me chuckle, even if it's incredibly frustrating that Ctrl+A doesn't work in so many places (i.e: it was originally "7", and I tried Ctrl+A, then typed "10")

For the longest time, I thought I was just fluffing my mouse movements... "aim better", etc...

Gmail keeps adding files to my Drive, and I do not want that... now I have to wait for it to finish, go and find it, move it to the trash, and then "delete forever".

But NO! I CLICKED ON THE DOWNLOAD BUTTON!

I clicked on the download button, and it added it to Google Drive. The "Organise in Drive" tooltip is showing! 😡

I smell a tampermonkey script coming.

Today I learned that iOS browsers can't render HEIC files (at least from what I read).

I also learned that they'll magically convert HEIC files to JPEG, when selected from "photos", but apparently not when selected from "filesystem"... which is ew, but I can't decide if browser-can-render trumps the lossy conversion when it comes to "originals" being uploaded.

I ALSO learned that... PNGs (e.g: screenshots) are converted to JPEG automagically as well.

Lovely.

Please correct me if I'm wrong.

I'm looking for some self-host / open source software to allow people to upload misc files, along with a description.

Description of what I'm after below... NextCloud (which I'm already using) is awkward because I'd need to produce one link per recipient.

Schematics are a form of communication... So communicate!

There's nothing worse than a mystery box, with signals going in, and signals coming out... and no explanation.

Being forced to reach for the datasheet, when you're trying to understand a schematic is bad. Avoid it.

I have so much music in my life, but I also feel like I don't have nearly enough. 😢

I'm trying to figure out what's going on here... but can't. I definitely miss working as a sound engineer for live music events (bands and musical theatre), even DJ sets were very fulfilling for me.

... is this "out loud" vs headphones (almost exclusive for some years now), or about the atmosphere, purpose, team work, common goal of such events.

... is this because I can't sit down and play (e.g: piano)

An STM32 NUCLEO board, with an onboard ST-Link... connected to st-util... connected to arm-none-eabi-gdb.

load - fine
cont - fine
^C - program appears to reset...

Is something going wrong for me, or should I be able to debug this in a normal way?

All sorts of other things appear to be behaving weirdly too. 😢

I'd really like to figure out why this firmware appears to be hanging while mounting a filesystem over 4-bit SD/MMC, but is fine with 1-bit...

So close! The internet points are real! 😀

Does anyone else think about this nerve semi-regularly? (shown in blue, on a giraffe)

"The recurrent laryngeal nerve connects the brain and the larynx. The nerve's route was relatively direct in our fish-like ancestors, but in vertebrates the nerve loops down from the head, around the aorta, and back up to the larynx. In a giraffe, that comes to a detour of several meters down the neck and back up again."

I feel like I'm loosing it... two boards behave differently, for what appears to be the same waveform.

I've just discovered that when using an incognito Chrome window, if you hover over an icon in the bookmark bar, it'll send a request to that URL. You do not need to click.

How do I know? I'm a weirdo who uses bookmarks to control my office lights, and I can turn them on/off without actually clicking the icon.

I'm looking for a good recommendation for a heist film (or similar, plans, tech, etc...)... funny and romance for bonus points! 🙃

I have ... a jet engine on the floor of my office. (as you do)

I'm figuring out some CAN gremlins.

I've understood and hopefully fixed the bug.

I decide to replay a CAN dump I took from a full system the other day.

It's quiet in the house, everyone else is asleep.

Everything looks good! No errors! 🥳

THE ENGINE TRIES TO STARTUP AND TAKE OFF! 😱

THE STARTER CLUTCH IS LOUD!

IT HAS A TEENY BIT OF JET A-1 FUEL IN THE LINES! STOP STOP STOP!

It gave me such a fright.

I am dumb. 🤣🤦‍♀️

How did I never know that vowels were separated by 3-3-5-5-5 constanants?!

There's something incredibly satisfying about taking a customer project for "a drive"... and for the resulting data to be most excellent.

Here are a pair of GPS tracks showing bits of the return journey... very exciting.

Another map, showing the route through Cirencester. A number of the arrows are pointing the wrong way (off-course or even backwards), but it's not so terrible.

I share with you, a lesson in noise and self-heating.

These three series all measure the same thing, in close proximity on the same PCB - temperature.

• The top (blue) shows the temperature read by a 9-axis IMU.
• The middle (orange) shows the temperature read by a digital barometer.
• The bottom (purple, noisy) shows the temperature read by an STM32's internal sensor.

Does anyone know what a realistic figure is for USB MSC transfer speeds over USB 1.1 / full-speed / 12 Mb/s?

I've just stumbled on this project, and it looks incredible!

I've never heard of "Snapshot GNSS", but conceptually, you just "listen" to the signal, and record it... then deal with the processing later (potentially in the cloud). No need for a full fix, no almanac, etc...

What's with this new two-stage login process people seem to be adopting?

Give me your username / email ... okay thanks ... you may now give me your password.
