  • Makes sense. I don’t think latency is a great issue when transferring large files, I would be more concerned about packet drop. (Unless latency is part of the reason the tracker thinks I’m too slow to bother requesting data from, which would explain why American-based trackers barely let me seed but local ones work great.) The overhead of TCP torrenting is about 3-4 % for me, and even if an IPv6 tunnel increases that to say 25 %, I will be able to use 80 % of my upload bandwidth for seeding, assuming IPv6 allows me to reach enough peers to request 1.6 Mb/s from me, which would be much higher than the current <1 %. My logic was that I could reach people that don’t have a publically reachable IPv4 port but an IPv6 one (because of IPv4 exhaustion of course), but now I understand that this is way less of an impact than I thought.


  • When inconsequential, capitalization gets messed up all the time, and the mistakes are overlooked: everyone understands that a weight labeled “10 KG” has a mass of 10 kg, but it’s better to get used to good practice for when it does matter. Thankfully, the “M/m” mistake of 9 orders of magnitude is usually caught by humans before it gets out of hand: you wouldn’t order 1 mm³ of wood instead of 1 m³. Very few quantities span 9+ orders of magnitude, for instance 10mΩ and 10MΩ resistors exist quite commonly, and you can imagine one being mistaken for the other with people copying each other’s handwritten component list. However, I’d bet that the bit/byte dichotomy confuses hundreds of people every day so we better make that clear by not breaking rules.

    BTW, the word is “megavolts”, not “MegaVolts” or any other capitalization, similarly “byte” is correct unless at the start of a sentence, with title case, or in German, and perhaps in words like “MByte”, which I discourage in favor of the full form or complete abbreviation.













  • Congratulations!

    Thanks for using the spoiler tag. It’s working now.

    And yes, I took into account that electronic nerds’ houses are different from most others.

    The story

    My Genius optical mouse was tracking poorly, even on patterned surfaces and mouse mats. I cleaned the lens and that didn’t help. So I used a knife to open the chip, which is a pinhole camera with a die that integrates the sensor, a basic image processing system, button, wheel and LED controller and a USB (or maybe also PS/2) interface. I cleaned the chip with alcohol (mainly to remove the dust that had landed on it while it was open) and reassembled the mouse to find that it made no effect on ots functionality. I ultimately found out that the focus distance was off and I fixed it by removing the rubber pads at the bottom.

    The chip appears to have no alphanumerical marking.

    Full picture of the PCB with this chip – it is slightly damaged because I needed to scrape off parts of it to allow the cover to come off; I also did this because I thought of readjusting the focus by slightly lowering the chip (by bending its legs).
