  • There’s a book on the subject written by Srdja Popovic.

    https://en.wikipedia.org/wiki/Blueprint_for_Revolution

    Summary: protests that start (and try to remain) non-violent have a greater chance to succeed, because they can attract more people to their cause.

    Critique: with some regimes, it’s not possible to non-violently protest. For non-violent protest to work, the environment must respect a minimum amount of human rights.

    Case samples:

    • US during the civil rights movement era: yes
    • USSR under Gorbachev: yes
    • Serbia under Milosevic: yes, with difficulty on every step (Popovic was there doing it)
    • Israel under Netanyahu: probably yes
    • China under Xi: practically no (not for long)
    • USSR under Kruschev/Brezhnev/Andropov/Chernenko: not really
    • Russia under Putin: no, don’t even hold a blank sheet of paper
    • Iran under Khamenei: only if you’re doing a bread riot
    • Saudi Arabia, USSR under Stalin, NK under the Kim dynasty: no, and execution would be a possible outcome

    …etc. In some places, you can’t organize. Then your only option is to fight. As long as you can publicly organize, definitely do so - it’s vastly preferable. :)



  • Opinion:

    Politically, the ayatollah can’t be toppled by foreseeable events, except if an Israeli strike should kill him. His successor in that case is unlikely to be milder. Netanyahu is also firmly in power due to special circumstances, and probably pretty safe from any Iranian attempts.

    Militarily, Iran has taken bigger losses, and has probably lost expensive and important parts of its nuclear programme - but not its stocks of highly enriched uranium, or its ability to launch ballistic missiles. From that perspective, if the Israeli strikes were meant to disarm Iran - they didn’t.

    Prognosis: they will trade more strikes and neither will achieve breakthrough success. Iran will lose more in the process.









  • You just missed my point about the 1.6MP elephant in the room.

    For your information, a global shutter sensor is not required in that scenario.

    A global shutter is advisable if you want to get detailed video of a fast moving object that fills a large percentage of the frame, without distorting the shape of the moving object. With rolling shutter, you still see, but get a distorted (elongated, stepped) moving object.

    • Does a bullet missing Trump fill a large percentage of the frame? No.
    • Do you need to see details of the bullet? No.
    • Is Trump moving too fast to photograph without distortion? No.
    • Do you need to autofocus on the bullet? No, and you can’t. It’s fine, you already focused on Trump.

    It follows that you don’t need global shutter, and you don’t care about autofocus. Merely using fast exposure and having a sensitive sensor + big lens (enabling you to use fast exposure) it will be sufficient.

    You also need luck, of course. I think the photographer who snapped that shot had a considerable amount of luck. They weren’t fumbling on their bag for a better X or Y. They were already taking a photo, most likely. Things just happened at the right time for them.

    As for practicality of modular and DIY equipment, yes, it may not be everyone’s preference.



  • How to make Saudia Arabia a normal society?

    • deny it income
    • deny it access to advanced technology
    • deny it legitimacy and cooperation

    Most importantly: stop using oil and natural gas sooner rather than later.

    Reasoning: the king stays in power by paying cops, security officials and prison guards - and paying people to shut up and tolerate the regime. Once the system runs low on money, things may change.

    Note: women in Europe made rapid progress at getting civil rights at a time when they were needed to run ammunition factories.

    It doesn’t have to be a world war - any development that makes it economically unavoidable that women start going to work outside their home, will change the role of women in society.


  • Autofocusing external lenses is a real problem. Fuck the lens makers indeed, as a result of which I’ve only used Raspberry Pi based systems with manual focus.

    Depth of field is a property of the lens, not the sensor.

    Sensors: if you want to take pictures in starlight, you can get IMX585 (hard due to market problems). If you want lots of pixels, 64 M is not a problem. If you want to photograph a bullet, you can get the low-pixel global shutter sensor, there is code around to take video at 500 fps (disclaimer: tiny video, extreme light level required).

    Cameras can be homebrewed, big integrators like Canon charge too much.





  • Don’t let the facts slow you down, eh.

    Attributing the existence of a country to an agency the country built, is a bit on the fast side, I think. The agency was born 1 year after Israel and built from scratch.

    Israel exists because millions of people didn’t have a place they could call their home country.

    Sadly, what has become of that country is not cheerful. Its war in Gaza seems to intend making life impossible in the sector (making a population’s life impossible in their homeland has a definition: genocide) and prime minister Netanyahu is grabbing for more power, likely with thoughts about “staying a bit longer”.

    Mossad (role: foreign intelligence) is an agency directly subordinated to the prime minister of Israel (unlike some others, e.g. Shin Bet (role: internal security and counterintelligence), which recently had its chief fired because he wouldn’t swear personal allegiance to Netanyahu). So, in the current political situation, there is credible suspicion that Netanyahu is creating a precedent and subordinating all intelligence agencies to his person - if not directly then indirectly.

    Mossad’s cooperation with foreign agencies has been punctuated by episodes of non-cooperation.

    I can point out several moments in history where the interests of Mossad contradicted, for example, the interests of the CIA. Threats were made, negotiations were held, some Mossad guys got caught and were imprisoned in the US.

    However, during less tense periods, agencies have also been trading tips. Mossad has built a highly successful “business” of assassinating people. It logically follows that if agency A knows that person X is on Mossad’s “hit list”, and they find out where X lives, then A won’t need to send a killer, but tips off Mossad. Intelligence agencies may sometimes (not cheerfully) share part of their technical networks with each other, but human networks - almost never. It can get their own agents killed or imprisoned, if another agency is careless.
