BLAST (biotechnology) Updated 2025-07-16
The NCBI free-to-use BLAST server: blast.ncbi.nlm.nih.gov/Blast.cgi. Having a centralized query server is fundamental, because the gain of sequence alignment really comes from having one huge database to link information together, which is best centralized.

What Elon Musk's 42,000 Satellites Could Do To Earth by Tech Insider (2020)
Source. Good primer. The main difference from older systems is that they fly closer to Earth, and are not geostationary. As a result, you have better latency. But you also need a bunc of them to have continuous coverage of an area.
Ciro's Edict #4 / Misc tech Updated 2025-07-16
I've finally had enough of Nvidia breaking my Ubuntu 21.10 suspend, so I investigated some more and found a workaround on the NVIDIA forums: stackoverflow.com/questions/58233482/next-js-setting-up-eslint-for-nextjs/70519682#70519682.
Thanks enormously to heroic user humblebee, and once again, Nvidia, fuck you.
The Dropout Updated 2025-07-16
It is good to watch the Out For blood in Silicon Valley (2019) documentary after this to see how the characters look like in real life. Many feel amazingly cast, very close to the original. The only great exception is the Indian dude, who is completely different. Was it that hard to find some indian dude who looked and felt a little more like the real one?
Uncertainty principle Updated 2025-07-16
The wave equation contains the entire state of a particle.
And a single vector can be represented in many different ways in different basis, and two of those ways happen to be the position and the momentum representations.
More importantly, position and momentum are first and foremost operators associated with observables: the position operator and the momentum operator. And both of their eigenvalue sets form a basis of the Hilbert space according to the spectral theorem.
When you represent a wave equation as a function, you have to say what the variable of the function means. And depending on weather you say "it means position" or "it means momentum", the position and momentum operators will be written differently.
Furthermore, the position and momentum representations are equivalent: one is the Fourier transform of the other: position and momentum space. Remember that notably we can always take the Fourier transform of a function in due to Carleson's theorem.
In precise terms, the uncertainty principle talks about the standard deviation of two measures.
We can visualize the uncertainty principle more intuitively by thinking of a wave function that is a real flat top bump function with a flat top in 1D. We can then change the width of the support, but when we do that, the top goes higher to keep probability equal to 1. The momentum is 0 everywhere, except in the edges of the support. Then:

Mahayana Updated 2025-07-16
Mahayana adds a bunch of stuff on top of the Pali Canon. Most of it appears to be random mysticism. Maybe there is something good in it... maybe.
Rust (video game) Updated 2025-07-16
The brutality of this game, the fact that you can get killed at any point, and all players accept that, is awesome.
tig (git UI) Updated 2025-07-16
This is good. But it misses some key operations, so much so that makes Ciro not want to learn/use it daily.
Blockchain.info Updated 2025-07-16
TODO who owns it? Are they reliable?
This helper dumps a transaction JSON to a binary:
bitcoin-tx-out-scripts() (
    # Dump data contained in out scripts. Remove first 3 last 2 bytes of
    # standard transaction boilerplate.
    h="$1"
    echo curl "https://blockchain.info/tx/${h}?format=json" |
    jq '.out[].script' tmp.json |
    sed 's/"76a914//;s/88ac"//' |
    xxd -r -p > "${h}.bin"
)
Their API limit witout key is 1 query per 10 seconds!!!

This is not a label that Ciro Santilli likes to give lightly. But maybe sometimes, it is inevitable.
