Polarization Updated +Created
Stack Overflow should pay its top contributors Updated +Created
One may dream.
If they belive that their reputation is a representative meaningful metric, then it should be fine!
And if not, then they should fix it.
Notably, more people would try to "game" the system by quickly answering lots of small impact answers which could tilt things off a bit. Not to mention straight out fraud.
So basically less money into developers doing useless new features for the website, and more money back into meaningful contributors.
How about 2k USD / month for the number one contributor of the year, going linearly down to 0 for the 200th? This would be 100k USD / month, so about 12 developers.

Cool data embedded in the Bitcoin blockchain / Largest ordinal inscription Updated +Created
We can get a list of the ordinals at: archive.org/details/bitcoin-ordinal-inscriptions.csv and then sort them by payload size with:
sort -k6 -n -t, ordinals.csv -o ordinals-sort-size.csv
This shows to us that as of block ~831k, there are 4 ordinals which are far far larger than any other between 3 MiB and 4 MiB, at about 10x larger than then 5th one d115a6e689086fd587e5032f24ba2a8c01f2f87cba758c9d5eb8cf7f6e9a816a
In those cases, a single inscription takes almost the entire block, and the inscribers must have had direct dealings with their mining pool:
As of 2024, all of the big ones were made in early 2023, so it seems that the trend has died down a bit.

ELF Hello World Tutorial / Minimal ELF file Updated +Created
It is non-trivial to determine what is the smallest legal ELF file, or the smaller one that will do something trivial in Linux.
In this example we will consider a saner hello world example that will better capture real life cases.

Ciro Santilli has become slightly obsessed with this story, and the main mastermind Ross Ulbricht.
Figure 1.
Ross Ulbricht's open laptop shortly after his arrest at the Francisco Public Library
. Source. He was running some GNOME based distro, could be Ubuntu from that photo, and likely is given that Ross once recommended Ubuntu to his flatmate.
The best article available so far is: www.theregister.co.uk/2019/01/29/how_i_caught_silk_road_mastermind (archive) which summarizes what one of the investigators said in a 2019 French computer security conference.
The key living posts are:
The big question is of course how libertarian free market ideologically motivated the website was, and how purely criminal greed it was.
The magnitude of the early operational security mistakes does make Ciro think that Ross did it "because he could" and "for the lolz" in a real world Breaking Bad way.
[i]n 2011," [I believe I will be] "creating a year of prosperity and power beyond what I have ever experienced before,
Silk Road is going to become a phenomenon and at least one person will tell me about it, unknowing that I was its creator."
Having this kind of feeling, is the greatest thing any human can have, and what motivates all great things.
Capitalizing in illegal things though is a cheat, big things take longer than a few years to reach, but reaching them is that much more satisfying as well.
Other interesting quotes:
I hated working for someone else and trading my time for money with no investment in myself.
which Ciro also feels, see don't be a pussy, and:
Everyone knows I am working on a bitcoin exchange. I always thought honesty was the best policy and now I didn't know what to do. I should have just told everyone I am a freelance programmer or something, but I had to tell half truths. It felt wrong to lie completely so I tried to tell the truth without revealing the bad part, but now I am in a jam. Everyone knows too much. Dammit.
The murder for hire allegations are also interesting: mashable.com/2013/10/03/silk-road-hits, he paid 80k dollars to undercover DEA agents!
Except for the fact that Ross was an 80 million Dollar drug lord, those accounts sound exactly like what you would expect from any other nerdy startup founder! The:
  • "just do it" strategy effectively going to a minimal viable product (manual transaction management!), while making many mistakes along the way, including hiring mistakes and successes when scaling is needed
  • the hardship of self bootstrapping your own social network (here with some kilos of mushrooms)
  • the variety of periods, from relatively calm, to hair pulling stress during big changes
It is also amusing to see very concretely the obvious fact that the FBI can get a subpoena for all accounts you ever had, e.g. they knew his laptop model from Amazon and brought a corresponding power cable to the arrest! If you are going to be a cyber criminal, don't use your real name, ever!
Should justice be blind? Maybe. But it does hurt for mere non-blind men to see it sometimes. Especially when drug liberalization is involved.
