C++
  • Hot take, C is better then C++. It really just has one unique footgun, pointers, which can be avoided most of the time. C++ has lots of (smart)pointer related footguns, each with their own rules.

  • No tritium found in fish one month after Fukushima water release
  • All that other stuff was filtered out, but the tritium is near impossible to separate, because it is chemically identical to the hydrogen in normal water.

    As for caesium, there are still detectable amounts of Cs-137 in most of the word from the thousands of atomic bomb tests. It's half life is just 30 years, but it will still be detectable for a hundred years or so because of the huge amount we released.

  • No tritium found in fish one month after Fukushima water release
  • A banana naturally has has around 15 Bq of potassium 40. Assuming a volume of 100 mL, mashed bananas have around 400 Bq/L.

    Currently, the treated water has around 250 Bq/L, around a fifth of mashed bananas. In other words, a banana smoothie could easily be more radioactive then the water as it was released.

    The banana's potassium 40 has a half life of more then a billion years, so it's not going anywhere, unlike the tritium who's amount will half every 11 years. Also, potassium is concentrated by many plants and animals, while tritium is not.

  • AI Fakes in Highschool and Middle School (USA)
  • Fake nudes of real people are generally illegal, regardless of if the nude is real, or photoshopped, or AI generated.

    People have been arrested and convicted for AI porn of real people.

    For now convictions seem to be confined to people who have already created/used more traditional CSAM (hidden cameras). This could just be because it is hard to catch someone simply generating images, so if someone with no record would be jailed for just fake nudes remains an open question. Fake nudes of fictional people are also very much an open question. Being very new technology, new laws have yet to be made, so feel free to write to lawmakers about where the line should be.

  • The ugly truth behind ChatGPT: AI is guzzling resources at planet-eating rates
  • And more importantly, take investor's money. Most tech company are constantly losing money and depend a continuous flow of investor money.

    Reddit lost 90 million dollars last year, that's why they did the IPO, so they could sell the problem to some sucker. Snapchat lost 1.3 billion last year, and would run quickly go bankrupt if people stopped investing.

    As usual, the best way to get rich quick is by selling a get-rich-quick scheme.

  • "Hardware Error" after power failure
  • Run the BIOS self tests.

    Something's definitely broken (TPM errors, self test errors, graphical artifacts), but I can't tell what from the image. I would guess motherboard problems, or a subtly damaged CPU.

    Could also be more then one problem in the case of over voltage (worst case consequence of PSU damage), or intermittent failure from under voltage (should be fixed with a new PSU).

    Teen rapper accidentally kills himself on social media video after pointing gun at his head and pulling trigger
  • Seriously, what did he expect? The first thing you learn before getting a gun is to never assume a gun is unloaded or safe, even if you just checked it. Never point a gun at anything you do not want to shoot. As always, safety rules are writen in the blood.

    I think it is highly unlikely someone gave him a gun without going over the basics of or of him intentionaly ignoring safety rules for the video.

  • Modulating and amplifying signals with (electro)magnets
    10maurycy10.github.io Modulating and amplifying signals with (electro)magnets. | thin threads

    This is a functional AM modulator (and with the help of a rectifier, an amplifier) built entirely out of transformers and inductors: (It does not look like there is gain here, because of the different impedance’s, but this does actually produce a stronger output signal than the modulating input.)

    How can graphite be an abrasive and a lubricant?

    Graphite is normally very soft and slippery, and is even able to act as a dry lubricant when finely powdered, however many sources claim that graphite powder can be highly abrasive, to the point of potentially destroying milling machines. Does anyone know how such a soft material can abrade metals?

    A simulation of a very long circuit.

    A simulation based on maxwell's equations and ohms law of a very long circuit, demonstrating how current can seem to travel faster then light.

    Position on piracy, etc.

    I am not familiar with the legal situation this instance's server and owner is in, are there any actions a user could take that could expose the operators to legal liability? Could the instance face problems if someone posts a link to pirated content? What about general discussion of piracy? Or any other possibly legally problematic content?
