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:
- create a GitHub issue at: github.com/cirosantilli/cirosantilli.github.io/issues/new or Giscus thread
- at mention Ciro's main Twitter account
For comments about China, first read:
and then create a GitHub issue at: github.com/cirosantilli/china-dictatorship/issues/new
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:
- email:
cirosantilli
with provider ProtonMail which has domain nameproton.me
. All lowercase and removing the placeholder characters<
and>
. Note that Ciro also controls the Gmail address with that same username, and keep in mind that dots are ignored in Gmail addresses. But ProtonMail preferred because why should we give our private minds to the CIA by default? Push notifications disabled. - Signal: username
cirosantilli.89
signal.me/#eu/BuJjV0enXYTOnFFc1FZV5LFcWodL1a2Oy9VZ5uyQU7xrYxqw+npIcaHBqghWudrI. 89 is a reference to Ciro Santilli's birth year 1989. Push notifications enabled, but treat like email unless we are actively chatting back and forth.
For other less good methods that will also work, use direct messages of the following profiles from under Section "Accounts controlled by Ciro Santilli":
- LinkedIn: www.linkedin.com/in/cirosantilli
- Reddit: www.reddit.com/user/cirosantilli
- Facebook: www.facebook.com/cirosantilli
- Telegram: telegram.me/cirosantilli. Note that end-to-end encryption is present on secret chats only, which don't have device sync. Ridiculous.
If you are a privacy freak or are going to tell Ciro state secrets Ciro has this GNU Privacy Guard public key: pubkey.gpg.

Things that are not nice such as:
- Taboola, Outbrain, and other chumbox
- BLOBs
- Europe cookie law
- adhesive inside mobile phones and more generally, planned obsolescence
- Jupyter Notebook
- typographical characters that look like ASCII ones, but are not the ASCII ones, e.g. typographical quotes, em-dash. The non-breaking hyphen is not even whitespace, and by def Why not stick to ASCII when ASCII is good enough?
- excessive encapsulation
- replacement of master and slave terminology from technology
- mailing lists. And to add insult to injury, HTML on mailing list messages instead of plaintext.
- blank lines in code added by people trying to increase clarity, especially when there is already indentation for that. Every blank line must be preceded by a line comment explaining what the following block is about, or removed.
- messaging software that force you to have a mobile phone
- advertisements by telephone/SMS
- "state" such as global variables and object members, long live functional programming?
- mosquitoes, the only intrinsically bad thing about tropical countries
- projects with slow compilation times
- Microsoft Windows
- the 2019 Chinese government
- e-learning websites that only allows verified teachers to write content. Cowards who can't handle ranking algorithms.
- domain-specific language
- a build system without an out-of-tree option
- non-linear Git history: stackoverflow.com/questions/20348629/what-are-advantages-of-keeping-linear-history-in-git
- visual programming languages like Scratch. Waste of time. Text programming languages are already equally as visual due to indentation:Just make good serious gamedev libraries and integrated development environments for those real languages instead.
if x == 0: x = 1
- software that prevents you from running as root. Let me fucking shoot myself in the foot if I want to. It is better than having to deal with your hand holding bullshit, which is done in a different way for every project. E.g.: stackoverflow.com/questions/17466017/how-to-solve-you-must-not-be-root-to-run-crosstool-ng-when-using-ct-ng/53099177#53099177
- Medium
- luxury goods
- euphemism
- closed access academic journals are evil
- websites without OAuth
- shower room without a window to the exterior (mould!!!)
- single programs with their interface split across multiple windows, e.g. GIMP, ZynAddSubFX
- graphical user interfaces
- logograms
- infinitesimals. Just use limit instead, please
- country
- knowledge olympiads
- programming languages without a decent dominating package system
- closed source offline software used by millions
- exams
- security through obscurities
- dots in Gmail address
- things in websites that look like links, and behave like links, but don't let you middle click to open them on a separate tab
- K-pop
- numerical computing language
- fiscal paradises
- when the front-end of an website changes an important permanent state, but the URL does not change
- splash screens: you should show boot messages so that people will know what to Google for when things fail. Do you think computer newbies will be afraid and have nightmares?
- milk chocolate: why would you eat that instead of dark chocolate if you are older than 10?
- to talk about something without giving the real name to not scare off the audience
- mathematical symbol that looks like a Greek letter but isn't. Or perhaps mathematical notation in general
- when more than two people gather to play a board game or video game, and two or more people start chatting on and on about random subjects rather than concentrating on the game
- watching television while eating. Same for reading, or doing basically anything else but eat. The only acceptable activity is talking relaxedly, not about work.
- noises coming out of your bicycle. It is so hard to find where they come to fix them!!!
- code drop
- private cars as opposed to public transport. As a cyclist, you can just see the effect that large roads have on nearby areas, it just destroys nature.
- closed standards
- double consonants that make no difference to sound. Dilema? Dilemma? Dillema? Dillemma? Please!
- social media websites that show stuff from people you don't follow when you don't explicitly want that, including things which are not ads, just random suggestions. Twitter starting being like that cirac a 2022. Facebook got worse around that time. It is a constant fight against those stupid websites.
- socks with short legs that don't protect your ankle/lower calf from cold/scratches/dirt, e.g. liner socks
- Presta valves. Why would such a flimsy tech have become so popular compared to the infinitely superior Schrader!
This was possible at the time without any login by using a 2010 profile ID dump from originally announced at: blog.skullsecurity.org/2010/return-of-the-facebook-snatchers since profile picture access was not authenticated.
The profile ID dump was downloadable through a BitTorrent named on Ubuntu 20.04 gives:This dump widely reported e.g. on Hacker News at: news.ycombinator.com/item?id=1554558.
fbdata.torrent
of about 2.8GB, mostly compressed. Doing:find . -type f | xargs sha256sum | sha256sum
2c9a739c9c5495e38ebab81fc67411b7c6562f139dcb8619901a3f01230efdd5
At some point however, Facebook finally started to require tokens to view public profile pictures, thus making such further collection impossible, e.g. as of 2021: developers.facebook.com/docs/graph-api/reference/v9.0/user/picture mentions:This is also mentioned e.g. at: stackoverflow.com/questions/11442442/get-user-profile-picture-by-id. This major privacy flaw was therefore finally addressed at some point, making it impossible to reproduce this project.
Querying a User ID (UID) now requires an access token.
Ciro downloaded 10 thousand of those pictures, and did facial extraction with: stackoverflow.com/questions/13211745/detect-face-then-autocrop-pictures/37501314#37501314
He then created single a video by joining 10 thousand of those cropped faces which can be uploaded e.g. to YouTube. Ciro later decided it was better to make those videos private however, as sooner later he'd lose his account for it.
Companies like YouTube blocking this kind of content is the type of thing that makes companies take longer to fix such gaping privacy issues, and is a bit like security through obscurity. A video makes it clear to everyone that there is a privacy issue very effectively. But people prefer to hide and look away, and then 99% of people who know nothing about tech get their privacy busted by actual criminals/government spies and never learn about it.

I am interested in getting into quantum computing because the this field seems like it could be promising. My wife is French and working for a French company in Paris and we are looking to relocate to the greater Paris region. I've heard good things from the company. I have only done basic undergrad physics in university but I'm very interested in learning more from a more concrete point of view, AMO seems really cool. I can handle low level programming well.

- Turned down two days later before anything.As evidenced by my Stack Exchange contributions, I love trying out new software to see if it works and how well. I love benchmarking it. And I love documenting what I observed in great detail to help others to choose the best software for them. I also love meeting various new people and understanding what they are up to and how I can help.
- job-boards.greenhouse.io/deepmind/jobs/6576118 Software Engineer, Hardware Design
At ARM and AMD I've worked on various different parts of the hardware cycle, notably C++ emulation and low level software. I just get this strong feeling that hardware and low level software design should be the easiest thing for machines to automate, as it is the area that requires the least amount of "common sense" information about the world.

This job seemed like a possibility as I've done some personal "data intensive" projects in the past (not distributed unfortunately, ~500 GB so it fit on my local disk), and I kind of enjoyed it and would be interested in trying out a more "data heavy" job like this for a change.

I really like the idea of using simulations to speed up development of ideas or AI. I've done this in my past jobs in the semiconductor industry, and a bit on side time tinkering with simple simulation games that might be useful to train AI. I'm curious to what you will be simulating! The general areas that your company operates in, biotech and PCB design are also in my interest.lI really like the idea of using simulations to speed up development of ideas or AI.

- job-boards.greenhouse.io/anthropic/jobs/4632830008 Software Engineer, ML Performance and Scaling
I just want to help achieve AGI so I don't need to work anymore. I can do non-glamorous things to achieve that goal, but eventually I'd inevitably get into research itself. I haven't done deep learning except basic examples, but I can handle low level stuff, and I want to learn.
Why Anthropic?I'm applying to any LLM companies, and the ones with more funding are more likely to have dumb coding jobs that I can do without a PhD in ML, and more likely to have the resources to reach some critical point if scaling continues. The small labs have the advantage of nimbleness to try new architectures, but they only employ PhDs.In one paragraph, provide an example of something meaningful that you have done in line with your values.

Ciro Santilli's LinkedIn profile: www.linkedin.com/in/cirosantilli/ see also: accounts controlled by Ciro Accounts.
LinkedIn fully complies with censorship imposed locally by the Chinese government, and does so in a non-transparent way: cirosantilli.com/china-dictatorship/linkedin.
It is hard to understand what the point of that website is, as it is basically just a more closed version of Facebook, but alas, it has flourished as the only place where people post more useful content compared to Twitter and Facebook. In any case, Ciro just applies the same unfollow policy to all of them: aggressively filter your social media follows.
Where blog is taken in a wide sense, including e.g. Medium, WordPress, Facebook, Twitter, etc., etc.
The main shortcoming of blogs is the lack of topic convergence across blogs. Each blog is a moderated castle. So who is the best user for a given topic, or the best content for a given tag, across the entire website?
The only reasonable free material we have for advanced subjects nowadays are university lecture notes.
While some of those are awesome, when writing a large content, no one can keep quality high across all sections, there will always be knowledge that you don't have which is enlightening. And Googlers are more often than not interested only in specific sections of your content.
Our website aims to make smaller subjects vertically curated across horizontal single author tutorials.
