  • Computers can really just do two things: copy data and do math. Anytime your your doing anything but copying data verbatim, there is math involved. Anytime your reformating, filtering or acting on data their will be some math involved.

    Take displaying an image: you can’t just copy image data to the screen, because it could have a different resolution, or color space, or be compressed. In all of those cases, you will need to do a lot of math to get things to work right.

    The exact math varies, in graphics, CAD or geospatial stuff, expect a lot of geometry. Any sort of statistics or classifier is going to involve a lot of linear algebra. Even simply storing data in s quickly accessable manner involves quite a bit of math.






  • 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.



  • 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).



  • Well first off, how nice/tolerant is your management? Do you have savings? Some companies can fire people over this stuff, other will just ignore it.

    The easiest (and least likely to make anyone mad) solution would just be to bring in your own machine and use celular internet. This way your setup will be completly seperate from the company network, and they can hardly claim you were exposing them to malware or anything. On the other hand you might have problems accessing devices like printers without copying files back and forth (are USB drives allowed?).
