Ciro Santilli's campaign for freedom of speech in China Updated 2025-07-16
Centerpiece: github.com/cirosantilli/china-dictatorship
Fully rendered at: github.com/china-dictatorship
The campaign has centered around publishing censored keywords on his Stack Overflow username, thus using his considerable Stack Overflow presence to sabotage the website in China. Here is an early web archive.
Chrysanthemum Xi Jinping with 六四 spice added by Ciro Santilli
. This was one of the profile pictures that Ciro Santilli used as part of his campaign.
Ciro later went on to prefer the "unmodified" Xi Jinping photo cover of some edition Xi Jinping Though, which also reminds Ciro very much of religious devotional pictures, e.g. those of Li Hongzhi.
Ciro understood that the best propaganda against a dictatorial enemy is recontextualized unmodified propaganda produced by the enemy itself. Their propaganda speaks for itself
Like most people in the West, Ciro has always been for political freedom of speech, and therefore against the Chinese government's policies.
However, the seriousness of the matter only fully dawned on him in 2015 when, his mother-in-law, a then a 63-year-old lady, was put into jail for 15 days for doing Falun Gong.
And all of this was made 100 times worse because Ciro deeply loves several aspects of China, such as food, language, art and culture, and saw it all being destroyed by the Communists: cirosantilli.com/china-dictatorship/does-ciro-santilli-hate-china
The rationale of this is to force the Chinese government to either:
- leave things as they are, and let censored keywords appear on Stack Overflow (most likely scenario)
- block Stack Overflow, and lose billions of dollars with worse IT technology
- disable the Great Firewall
In the beginning, this generated some commotion, but activity reduced as novelty wore off, and as he collected the reply to all possible comments at: github.com/cirosantilli/china-dictatorship.
This campaign has led him to have an insane profile view/reputation ratio, since many people pause to look at his profile. He is point "A" at the top right corner of Figure 2. "Scatter plot of Stack Overflow user reputation vs profile views in March 2019 with Ciro Santilli marked as A":
Ciro feels that the view count started increasing more slowly since 2020 compared to his reputation, likely every single Chinese user has already viewed the profile.

They do seem to have been very innovative, and have had a very good work culture. They also had a huge impact on the Silicon Valley startup scene.
Some products they are known for:
- oscilloscopes
- Atomic clocks, notably highly portable ones, see e.g. Video "Inside the HP 5061A Cesium Clock by CuriousMarc (2020)"

Making the Cisco connection Updated 2025-07-16
Nothing phenomenally new on the early days to add on top of Video "Nerds 2.0.1 excerpt about Cisco (1998)", but a few new good points:
- Cisco at one point became the largest company by market capitalization. This wore off a bit as of 2020.They used this overvalued stock in part to buy many other (often also overvalued) up and coming companies. This acquisition spree strategy was apparently not the norm at the time. rohitnair.wordpress.com/2011/12/13/cisco-history-cisco-systems-history-and-trivia-brand-history-and-trivia/ mentions they have bought more than 140 companies since, and that they call this strategy "Build, Buy And Partner"
- a big part of what Cisco did was to allow cheap local communication in-campus. At that time, the ARPANET was already up and running, but their "routers", called Interface Message Processors were very expensive at about $100,000, and to send data across the campus you had to go through them, which meant expensive bandwidth. The routers sometimes failed, and the fallback was to send students around with disks: "sneakernet". They needed new local protocols and hardware to efficiently connect different campus networks.

- Cisco was a pioneer in having an Internet support forum. Customers could also help one another. This was fundamental in scaling support, as they grew so fast it would be impossible to hire a support team large enough without the help of the forum.
- Cisco gave out source code to some customers who would then implement protocols they cared about, and Cisco would then merge it back

Ciro Santilli's mother loves that one. Even though she was constantly worried that if Ciro had studied physics he would be poor and starve, a factor which led him to study engineering instead, one of the greatest mistakes of his life. don't be a pussy.
Marie Curie Updated 2025-07-16
Like all big names in science, she was at the right place at the right time and with the right interest and passion.
Notably, the man she married, Pierre Curie, happened to be a the world master at precisely the technique that she needed to carefully measure radioactivity: he had the most precise electrometers in the world, which allowed to detect small amounts of radioactivity via the ionization of air by radiation . These used piezoelectricity, which Pierre Curie co-discovered with his brother.

Some key specs:
- SoC:
- name: RP2040. Custom designed by Raspberry Pi Foundation, likely the first they make themselves rather than using a Broadcom chip. But the design still is closed source, likely wouldn't be easy to open source due to the usage of closed proprietary IP like the ARM
- dual core ARM Cortex-M0+
- frequency: 2 kHz to 133 MHz, 125 MHz by default
- memory: 264KB on-chip SRAM
- GPIO voltage: 3.3V
Raspberry Pi Pico W MicroPython example Updated 2025-07-27
An upstream repo at: github.com/raspberrypi/pico-micropython-examples
Some generic Micropython examples most of which work on this board can be found at: Section "MicroPython example".
The examples can be run as described at Program Raspberry Pi Pico W with MicroPython.
- rpi-pico-w/upython/led_on.py: turn on-board LED on and leave it on forever. Useful to quickly check that you are still able to update the firmware.
- rpi-pico-w/upython/led_off.py: turn on-board LED off and leave it off forever
- rpi-pico-w/upython/pwm.py: pulse width modulation. Using the same circuit as the rpi-pico-w/upython/blink_gpio.py, you will now see the external LED go from dark to bright continuously and then back

Mastodon (software) Updated 2025-07-16
Of course those racist Nazis are a bunch of idiots, but how can you be surprised when freedom-of-speech focused tech gets used by them? www.theverge.com/2019/7/12/20691957/mastodon-decentralized-social-network-gab-migration-fediverse-app-blocking
Obviously, a few large instances dominate the user base for all practical purposes: kevq.uk/centralisation-and-mastodon/. And likely the network splits into hate-speech/non-hate-speech blacklist boundaries. And since the dominating closed networks will never lose user counts (???), the only instance that dominates will be the main hate speech one.
The flagship instance was mastodon.social and then in 2020 they closed signups for it and created a secondary mastodon.online.
The multi-instance thing is confusing and problematic. E.g. replies and likes might not show up across instances in some occasions: www.reddit.com/r/Mastodon/comments/ynt7ta/is_there_a_way_to_see_post_replies_displayed_on/
The "advanced interface" feature is bad. Really bad. MacOS file browser inspired.

Mathematical formulation of quantum field theory Updated 2025-07-16
The Dirac equation, OK, is a partial differential equation, so we can easily understand its definition with basic calculus. We may not be able to solve it efficiently, but at least we understand it.
But what the heck is the mathematical model for a quantum field theory? TODO someone was saying it is equivalent to an infinite set of PDEs somehow. Investigate. Related:
The path integral formulation might actually be the most understandable formulation, as shown at Richard Feynman Quantum Electrodynamics Lecture at University of Auckland (1979).
Quantum electrodynamics by Lifshitz et al. 2nd edition (1982) chapter 1. "The uncertainty principle in the relativistic case" contains an interesting idea:
The foregoing discussion suggests that the theory will not consider the time dependence of particle interaction processes. It will show that in these processes there are no characteristics precisely definable (even within the usual limitations of quantum mechanics); the description of such a process as occurring in the course of time is therefore just as unreal as the classical paths are in non-relativistic quantum mechanics. The only observable quantities are the properties (momenta,
polarizations) of free particles: the initial particles which come into interaction, and the final particles which result from the process.
