Porn vlog Updated 2025-12-13
This is a porn style defined by Ciro Santilli as:
  • content is designed and owned by the actors
  • full face reveal
  • doing normal vlog things like talking, visiting places, eating, etc., not just fucking
Ciro believes that this is an interesting type of pornography, as it feels more natural and humane than all the horrible trash that comes out of horrendous professional mainstream porn industry.
Yes, it could go down the YouTube/Instagram alley, and lead the vloggers to do things they wouldn't normally do because of the audience. But who is to say that Ciro Santilli doesn't do the same on Stack Overflow to some extent?
That type of porn requires some big courage to make. Or balls if you will. Kudos to those creators, as it is so taboo it could greatly impact their future job prospects.
The travel sex vlog appears to be the most popular way to do it. Presumably the reason being that you would not be able to interact with people in a normal job, so to keep things interesting you need to go to some random places.

The project kind of died circa 2020 it seems, a shame. Likely they funding ran out. The domain is dead as of 2023, last archive from 2022: web.archive.org/web/20220331022932/http://gvgai.net/ is marked as funded by DeepMind. Researchers really should use university/GitHub domain names!
Similar goals to Ciro's 2D reinforcement learning games, but they were focusing mostly on discrete games.

Paris Updated 2025-12-13
Ciro Santilli lived in Paris for a few years between 2013 and 2016, and he can confirm the uncontroversial fact that "Paris is Magic".
Not just one type of magic though. Every quarter in Paris has its own unique personality that sets it apart and gives it a different mood.
Ciro knows Paris not from its historical facts, but from the raw feeling of endless walks through its streets in different times of the year. Ciro is a walker.
Maybe one day Ciro will expand this section to try and convey into words his feelings of love for the city, but maybe the effort would be pointless. Maybe such feelings can only be felt by other free-roaming walker souls living in the city, and that is both beautiful and a shame.
Ciro had written the following in the past before he lived in smaller cities, started cycling and joined the Street reclamation movement he thought:
Paris is a friendly city to walkers, as it is not too large, and does not have too many extremely busy roads, you can basically cross all of it on foot.
Perhaps compared to São Paulo City, which is what he knew before that was true. But no, his standards have improved since. Paris has way too many cars. The noise of internal combustion engine vehicles is extremely annoying. And because there are too many personal vehicles, cars have to horn a lot to fight for space. Fuck cars. Paris has been making a big cycling push in the early 2020's, and that is great. But it is still far, far from good.
How to contact Ciro Santilli Updated 2025-12-25
Ciro Santilli is very happy to meet people with related interests, he really loves his like-minded online friends. Even if you don't have something a specific goal in mind for the contact, please just say hi.
To contact Ciro publicly about any general subject that is not covered in a more specific GitHub repository, including saying hi or suggestions about his website either:
Publicly viewable contact is preferred if possible to more effectively share Ciro's wisdom with the world.
But if you feel more comfortable with private contact, no problem, either:
For other less good methods that will also likely work, use direct messages of the following profiles from under Section "Accounts controlled by Ciro Santilli":Ciro's Twitter DMs are also open, but note that Ciro receives endless Chinese language SPAM there which Twitter is doing nothing to combat, so it's not as reliable.
If you are a privacy freak or are going to tell Ciro state secrets Ciro has this GNU Privacy Guard public key: pubkey.gpg, but it's not something that he has ever really used.
Disqus comments were removed from his website in 2019-05-04, a manual dump is available here, removal rationale at: why Ciro Santilli removed Disqus comments from his website in 2019-05-04.
Videos of all key physics experiments Updated 2025-12-25
It is unbelievable that you can't find easily on YouTube recreations of many of the key physics/chemistry experiments and of common laboratory techniques.
Experiments, the techniques required to to them, and the history of how they were first achieved, are the heart of the natural sciences. Without them, there is no motivation, no beauty, no nothing.
School gives too much emphasis on the formulas. This is bad. Much more important is to understand how the experiments are done in greater detail.
The videos must be completely reproducible, indicating the exact model of every experimental element used, and how the experiment is setup.
A bit like what Ciro Santilli does in his Stack Overflow contributions but with computers, by indicating precise versions of his operating system, software stack, and hardware whenever they may matter.
It is understandable that some experiments are just to complex and expensive to re-create. As an extreme example, say, a precise description of the Large Hadron Collider anyone? But experiments up to the mid-20th century before "big science"? We should have all of those nailed down.
We should strive to achieve the cheapest most reproducible setup possible with currently available materials: recreating the original historic setup is cute, but not a priority.
Furthermore, it is also desirable to reproduce the original setups whenever possible in addition to having the most convenient modern setup.
This project is to a large extent a political endeavour.
Someone with enough access to labs has to step up and make a name for themselves through the huge effort of creating a baseline of amazing content without yet being famous.
Until it reaches a point that this person is actively sought to create new material for others, and things snowball out of control. Maybe, if the Gods allow it, that person could be Ciro.
Tutorials with a gazillion photos and short videos are also equally good or even better than videos, see for example Ciro's How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in bacteria for an example that goes toward that level of perfection.
The Applied Science does well in that direction.
This project is one step that could be taken towards improving the replication crisis of science. It's a bit what Hackster.io wants to do really. But that website is useless, just use OurBigBook.com and create videos instead :-)
We're maintaining a list of experiments for which we could not find decent videos at: Section "Physics experiment without a decent modern video".
Ciro Santilli visited the teaching labs of a large European university in the early 2020's. They had a few large rooms filled with mostly ready to run versions of several key experiments, many/most from "modern physics", e.g. Stern-Gerlach experiment, Quantum Hall effect, etc.. These included booklets with detailed descriptions of how to operate the apparatus, what you'd expect to see, and the theory behind them. With a fat copyright notice at the bottom. If only such universities aimed to actually serve the public for free rather than hoarding resources to get more tuition fees, university level education would already have been solved a long time ago!
One thing we can more or less easily do is to search for existing freely licensed videos and add them to the corresponding Wikipedia page where missing. This requires knowing how to search for freely licensed videos:

Ciro Santilli's 2021 cycling accident Updated 2025-12-25
Ciro had a small accident in 2021. It wasn't ultra serious, a few cuts, but could have been worse. Here's a post mortem.
Ciro was going to cycle 120 km between two locations he had never cycled before. Ciro had cycled this distance before many many times, so he thought he could do it.
What went wrong:
  • on both ends were cities, larger than those Ciro is used to
  • on the start, was a port city. You do not want to cycle in port areas, ever! Lots of trucks, narrow side-walks, bad road, danger danger!
  • on both sides, endless suburbia. This means you have to check your map every 3 seconds to know which little stress to turn, which is very hard without a way to attach your map to your bike. Ciro had his on his pocket. You lose a lot of time like that!
  • there wasn't a lot of sunlight at the time of the year. Not critical, but still, less than ideal.
  • during the ride, part of the "well documented and safe cycle route" was closed off for repairs. It was unclear what the best alternative would be. Ciro went down a path, but it turned to be horrendous countryside, he had to pull his bike over fences
  • by then, Ciro was tired and a bit late. He had only eaten sweets all day long. They give you calories, but there's always something missing in them.
  • Ciro arrived at the very very large target city, and it was getting dark, and it was rush hour, lots of cars. This was already back on the official bike path, but even those paths are tortuous in suburbia
  • also, Ciro was meant to meet his wife later, and he was in a rush, worried that she would be worried about him
  • at one point, Ciro took the wrong turn for a few hundred meters
  • he realized, and turned back
  • when coming back, now extra impatient because o the wrong turn, the place he had come from was actually one way street for a very short while until the right turn, so Ciro went against the correct direction...
  • a car came. It was relatively slow, because the road was slight uphill for the car, and a turn. The slight downhill also meant Ciro was going a bit faster than he realized
  • Ciro tried to go into the sidewalk anyways to make sure he was clear off the car (he was already). When he tried, the wheel stuck, and he flew forward, hitting a wall slightly
This was a perfect example of how many small things add up to an accident.
You have to know when you are tired and hungry and impatient. This is where huge danger lies.
Stop at a shop, eat, sit down. Darkness is not that dangerous if you have lights.
Take a train outside of large cities if needed. Crossing large cities is not something to be taken lightly. You need calm and time to do so safely.

ELF Hello World Tutorial / SHT_STRTAB Updated 2025-07-16
Sections with sh_type == SHT_STRTAB are called string tables.
They hold a null separated array of strings.
Such sections are used by other sections when string names are to be used. The using section says:
  • which string table they are using
  • what is the index on the target string table where the string starts
So for example, we could have a string table containing:
Data: \0 a b c \0 d e f \0
Index: 0 1 2 3  4 5 6 7  8
The first byte must be a 0. TODO rationale?
And if another section wants to use the string d e f, they have to point to index 5 of this section (letter d).
Notable string table sections:
  • .shstrtab
  • .strtab

TODO is his real birthname "Luke Dash Jr."?
Apparently he had his coins stolen in January 2023, then worth $3.5m: blog.cryptostars.is/luke-dashjr-an-original-bitcoin-developer-loses-all-his-btc-88421c395ce5p...

By default, NASM places a .symtab on the executable as well.
This is only used for debugging. Without the symbols, we are completely blind, and must reverse engineer everything.
You can strip it with objcopy, and the executable will still run. Such executables are called "stripped executables".
Used to identify organic compounds.
Seems to be based on the effects that electrons around the nuclei (shielding electrons) have on the outcome of NMR.
So it is a bit unlike MRI where you are interested in the position of certain nuclei in space (of course, these being atoms, you can't see their positions in space).

What's Nuclear Magnetic Resonance by Bruker Corporation (2020)
Source. Good 3D animations showing the structure of the NMR machine. We understand that it is very bulky largely due to the cryogenic system. It then talks a bit about organic compound identification by talking about ethanol, i.e. this is NMR spectroscopy, but it is a bit too much to follow closely. Basically the electron configuration alters the nuclear response somehow, and allows identifying functional groups.

. Source. The ring has a purity of 99.96%, weighs 5.3 kg, and is approx 11 cm in diameter. It is enough plutonium for one bomb core. Which city shall we blow up today?
Ciro Santilli is mildly obsessed by nuclear reactions, because they are so quirky. How can a little ball destroy a city? How can putting too much of it together produce criticality and kill people like in the Slotin accident or the Tokaimura criticality accident. It is mind blowing really.

ELF Hello World Tutorial / .strtab Updated 2025-07-16
Holds strings for the symbol table.
This section has sh_type == SHT_STRTAB.
It is pointed to by sh_link == 5 of the .symtab section.
readelf -x .strtab hello_world.o
outputs:
Hex dump of section '.strtab':

  0x00000030 61727400                            art.

ELF Hello World Tutorial / STT_NOTYPE Updated 2025-07-16
Then come the most important symbols:
Num:    Value          Size Type    Bind   Vis      Ndx Name
  4: 0000000000000000     0 NOTYPE  LOCAL  DEFAULT    1 hello_world
  5: 000000000000000d     0 NOTYPE  LOCAL  DEFAULT  ABS hello_world_len
  6: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT    2 _start
hello_world string is in the .data section (index 1). It's value is 0: it points to the first byte of that section.
_start is marked with GLOBAL visibility since we wrote:
global _start
in NASM. This is necessary since it must be seen as the entry point. Unlike in C, by default NASM labels are local.
Now that we've done one section manually, let's graduate and use the readelf -S of the other sections:
  [Nr] Name              Type             Address           Offset
       Size              EntSize          Flags  Link  Info  Align
  [ 2] .text             PROGBITS         0000000000000000  00000210
       0000000000000027  0000000000000000  AX       0     0     16
.text is executable but not writable: if we try to write to it Linux segfaults. Let's see if we really have some code there:
objdump -d hello_world.o
gives:
hello_world.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000000000 <_start>:
   0:       b8 01 00 00 00          mov    $0x1,%eax
   5:       bf 01 00 00 00          mov    $0x1,%edi
   a:       48 be 00 00 00 00 00    movabs $0x0,%rsi
  11:       00 00 00
  14:       ba 0d 00 00 00          mov    $0xd,%edx
  19:       0f 05                   syscall
  1b:       b8 3c 00 00 00          mov    $0x3c,%eax
  20:       bf 00 00 00 00          mov    $0x0,%edi
  25:       0f 05                   syscall
If we grep b8 01 00 00 on the hd, we see that this only occurs at 00000210, which is what the section says. And the Size is 27, which matches as well. So we must be talking about the right section.
This looks like the right code: a write followed by an exit.
The most interesting part is line a which does:
movabs $0x0,%rsi
to pass the address of the string to the system call. Currently, the 0x0 is just a placeholder. After linking happens, it will be modified to contain:
4000ba: 48 be d8 00 60 00 00    movabs $0x6000d8,%rsi
This modification is possible because of the data of the .rela.text section.
