MIDI Updated 2025-07-16
In simple terms, represents keystrokes of a piano, but it can likely also represent other effects (TODO confirm: bend, vibrato, slides, attack strength)
Can contain multiple parallel tracks as seen from the Wikipedia example: en.wikipedia.org/wiki/File:MIDI_sample.mid
You can see what it contains well with GUI music editor.
MIDI is fun. It is a basic high level representation of most instrumental music, including beats.
To actually listen to MIDI, you need a software synthesizer, which knows what sound to make for each note. One way to specify such instruments is the SoundFont file format.
Military-industrial complex Updated 2025-07-16
This is notably what the United States emerged to be after World War II. But it was likely what Nazi Germany also was, and many other superpowers.
Ciro Santilli feels that much more relevant would be to also include academia as in "military-industrial-academic" complex, the Wikipedia page actually mentions precedents to this idea.
The addition of congress/politicians is also relevant.
But hey, the name wouldn't sound so slick with three parts.
It is basically in this context that American science and technology flourished after World War II, including notably the development of quantum electrodynamics, Richard Feynman being a prototypical example, having previously worked on the Manhattan Project.
Computer programming Updated 2025-07-16
Programming is hard. To Ciro Santilli, it's almost masochistic.
What makes Ciro especially mad when programming is not the hard things.
It is the things that should be easy, but aren't, and which take up a lot of your programming time.
Especially when you are already a few levels of "simple problems" down from your original goal, and another one of them shows up.
This is basically the cause of Hofstadter's law.
But of course, it is because it is hard that it feels amazing when you achieve your goal.
Putting a complex and useful program together is like composing a symphony, or reaching the summit of a hard rock climbing proble.
Programming can be an art form. There can be great beauty in code and what it does. It is a shame that this is hard to see from within the walls of most companies, where you are stuck doing a small specific task as fast as possible.
Coulomb's law Updated 2025-07-16
Static case of Maxwell's law for electricity only.
The "static" part is important: if this law were true for moving charges, we would be able to transmit information instantly at infinite distances. This is basically where the idea of field comes in.

Computer security Updated 2025-07-16
As mentioned at Section "Computer security researcher", Ciro Santilli really tends to like people from this area.
Also, the type of programming Ciro used to do, systems programming, is particularly useful to security researchers, e.g. Linux Kernel Module Cheat.
The reason he does not go into this is that Ciro would rather fight against the more eternal laws of physics rather than with some typo some dude at Apple did last week and which will be patched in a month.
Protesters were posting large chunks of text multiple times into the blockchain as a way to protest against the controversial increase of block size.

I like big blocks and I can not lie

from the Baby Got Back hip-hop song.

Time to roll out bigger blocks
which is likely a copy of an email from the bitcoin development mailing list. This message is repeated dozens of times in other transactions.

Ciro Santilli would like to fully understand the statements and motivations of each the problems!
Easy to understand the motivation:
Hard to understand the motivation!
Mindustry Updated 2025-07-16
Conveyor belt 2D top down mining like Factorio, but with more emphasis on tower defense/real-time strategy, PvP looks a lot like StarCraft or Age of Empires.
As of pre alpha 135, the most annoying thing is that you can't easily start a campaign scenario from fresh, if you lose you have to start from wave 1 but with everything already half built as you left it. This gives you a huge advantage...
It is also annoying that you have to manually rebuild everything that was destroyed afer each attack, unless you have some unit that you can only unlock later on...
mindustry-unofficial.fandom.com/wiki/Future_Content#New_Google_Play_Listing suggests freemium features being considered, but they are mostly minor or plaform specific. There seems to be no server list by default however, making the Steam multiplayer freemium valuable.
It is a bit annoying that you have to unlock the tech tree little by little in campaign, but it does serve as a reasonable introduction to the general order of development. Games with progression state are boring, except when there is permadeath. But custom play scenarios have everything unlocked immediately, much better.
It is very cool that you can copy chunks of buildings as macros, and save them for later.
The game runs very well it feels like.
The logic blocks are particularly interesting, and allow you to program a block yourself.
