jalk··on Guitar amp and effects pedal built on the Waveshare ESP32-S3-Touch-AMOLED-2.06
The README[1] states that you should connect a usb audio interface to the board, as it runs in host mode

jalk··on Functional Mechanical Sympathy [video]
Since 2011 according to this: https://martinfowler.com/articles/mechanical-sympathy-princi...
jalk··on A 386 PC for Your RP2350
IIRC Emacs took up a significant number of disks
jalk··on Tension wood: A 'muscle' that can both bend and straighten plants
>NEVER TOP YOUR TREES

Kind of annoying when all the fruit is several meters out of reach

jalk··on Transfer files over an Ethernet patch cable
I had quite a few cables with a yellow crimp "jackets" just behind the RJ45. IIRC they came with DSL modems / routers
jalk··on Rapid warming may tip AMOC at 2°C, slower warming may avert collapse
Pretty trivial to replace CFC with HCFC gases (which breaks down more easily in the atmosphere) compared to moving away from fossil fuels.
jalk··on Librepods: AirPods liberated
You have to put them in pairing mode first: For airpod pros: Open the lid, keep the earbuds in the case, double tap your finger on the case just below the green led, The led should start to flash white and the airpods now appear in the device list in linux so that you can pair with them. Non-pro have an physical button on the rear IIRC.
jalk··on Parse, Don't Validate (2019)
An explicit type
jalk··on Gnome dev gives fans of Linux's middle-click paste the middle finger
I have it the opposite way. Moving my right hand from the keyboard to the mouse doesn’t save me time - so as with most things: YMMV
jalk··on How uv got so fast
There is definitely also a manager dick-measuring contest based on headcount, going on in large orgs.
jalk··on ULID: Universally Unique Lexicographically Sortable Identifier
Not sure what you mean by cryptographic strength - they are both Unique ID generators, not meant for anything related to cryptography.

UUIDv7 has 62 bits of random data, ULID uses 80 bits, so if anything ULID is "stronger" (meaning less chances of generating the same id within the same millisecond)

jalk··on Turtletoy
I stumbled over your string art turtle some time ago and like one of the commenters on [1], I was wondering about your tool to create points from a image

jalk··on Datacenters in space aren't going to work
Sounds like the people behind Solar Roadways found a new project.
jalk··on Precise geolocation via Wi-Fi Positioning System
Because all the conference rooms were already booked.
jalk··on Show HN: JermCAD – A YAML-powered, vibe-coded, browser-based CAD software
What resources will it pull away if it’s unmaintained?
jalk··on Show HN: I scraped 3B Goodreads reviews to train a better recommendation model
Not a great analogy, since a digital copy leaves the original intact unlike your apples
jalk··on Cloudflare tells U.S. govt that foreign site blocking efforts are trade barriers
Different countries have different laws regarding what falls under freedom of speech. The CDN providers say they take a net-neutrality stance. If a court order from a specific country tells them to block certain sites, I'm pretty sure they will comply, but only for clients coming from within that country.
jalk··on Cloudflare tells U.S. govt that foreign site blocking efforts are trade barriers
You are missing the point. Blocking a CDN providers IP range, means blocking all the websites using the CDN - not just the nazi-poster.com.
jalk··on Scientists growing colour without chemicals
I've heard that a major hurdle for these "cell-factories", is moving from lab to industrial scale. Ofc initial cost of the product is typically also a lot higher, but that is the same of any product addressing externalities of existing production
jalk··on Tiny electric motor can produce more than 1,000 horsepower
28 pounds - that's gigantic compared to this https://now.tufts.edu/2011/09/05/worlds-smallest-electric-mo...
jalk··on Oxy is Cloudflare's Rust-based next generation proxy framework (2023)
The article states that it's a proprietary project
jalk··on How ancient people saw themselves
Thanks, I see your point. Was not trying to be snarky/funny, but rather come with counter example to parent. I was thinking about the (recent) "Era of globalization" - but perhaps that is too short of a time span to be called an era

jalk··on California Will Stop Using Coal as a Power Source Next Month
[1] shows that they their coal plants have not been sitting idle i 2025 and are producing close to what they did in 2024. [2] shows that coal based electricity produced is still increasing, but their overall CO2 emissions / kWh is lowering [3]

jalk··on I built ChatGPT with Minecraft redstone [video]
Hoping the answer is: we used ChatGPT to create the build :)
jalk··on Solar leads EU electricity generation as renewables hit 54%
You must have some other sources than that site. Downloaded the CSV, and at the risk of misinterpreting the columns here is some simple filtering:

% of total energy generation

  EU Coal   9.64%
  US Coal  14.88%  
  CH Coal  57.77%

  EU Solar 11.19%
  US Solar  6.91%
  CH Solar  8.32%
Largest generation source

  EU Nuclear 23.57%
  US Gas     42.51%
  CH Coal    57.77%
This ofc only says something about generation and not consumption
jalk··on There is a huge pool of exceptional junior engineers
I was thinking about basic tool use. I expect a junior engineer candidate to wield a computer way better than my mom. They are applying for a junior engineer position not and apprenticeship starting with close to zero training. I have no problem with candidates who stumble and make awkward choices during the interview, as juniors by definition lack experience and the interview process is a stressed situation.
jalk··on There is a huge pool of exceptional junior engineers
Some points in parent comment are absolutely valid IMO. Would you hire a carpenter who walks back and forth to his toolbox to pickup at single nail at a time and then use the hammer with both hands near the head. And when cutting a 4x4 beam will use 1-inch strokes with the handsaw (again with two hands).
jalk··on A SQL Heuristic: ORs Are Expensive
That was the extreme case - the multi-scan would be gotten if a casual reader tried your (neat by all means) AND-only query on a non-indexed table (or partially indexed for that matter).
