  • Sleep, wait until the end. Just keep mostly going as usual, I won’t care about anything afterwards.

    Only difference, I’d donate all my money. Perhaps, I’d try to get one of those smaller loans some banks offer instantly (without giving a reason) and donate that too. Not sure if mine does that as well.

    But perhaps if I wasn’t a coward and nobody knew I was going to die anyway, I’d attempt to commit suicide for statistical reasons.

    Makes me think about time travel again, because in this case the event could be caused by the time travel. I mean, the traveller goes back in time to cause an event that already happened. Perhaps that’s the only reason why I was going to die.
    Could it work this way?
    Oh, wait, that’s how it was in Interstellar, no? If you travel to the past you can only do things that cause you to travel to the past and do the exact same things.
    Huh…

    I am getting off-topic.





  • That said, I’m a heavy phone user, and I’ve never had a phone that reliably lasts me a full day.

    Same. This time I just said “fuck it”, and got a phone with huge battery. I mean, really huge. Lasts me 3 days when kept between ~ 20 - 90%. God knows what that percentage really means though.
    It still shows 3.68V at “5%”, and keeps charging long past “100%”, so the way to ensure actual full charge is only with a USB tester. It also has some weird bugs with charging, so I recommend using a regular dumb 5V-only adapter or charge-only cable. In short - repeating split-second overvoltage on QC adapters, and no PC data after charging with original adapter until restart.
    I don’t need to charge it during the day, so this is OK enough.

    Anyway, most people would probably not want this. The battery is 22,000 mAh. Yes, really. And the phone is also 27.5 mm / 1.08 inch thick and 647g / 1.43lbs heavy. As I said, most people would probably not want this.

    For comparison with your Pixel 2, it’s like 3 and a half of them stacked thick, and 4 and a half of them heavy.

    Ulefone Armor 24. A cheap bug-ridden experience. However, a unique one.







  • A bit unrelated, but if you have DD-WRT on WiFi router with USB, you can install Entware. There’s also a few games.

    I used to play Tetris (vitetris) on my old WiFi router. I also tried to compile doom_ascii for MIPS, but I wasn’t successful and gave up. That was 5 months ago, so I basically forgot everything I tried already.
    I have also tried to compile it directly on the WiFi router, but it kept crashing even when I killed all running services (including SSH and Telnet so I had to use console, at least it’s 115,200 baud) that weren’t necessary. I think 32MB of RAM was my problem.
    Anyway, I doubt it would run on it anyway, but at least I tried.

    List of games available (at least for MIPS): angband, cavezofphear, crawl, gnuchess, minesweep-rs, nethack, rcon, sudoku-tui, superstartrek, tty-solitaire, vitetris, zork.

    Edit: Hmm, it seems at least very few Netgear switches may be supported by OpenWRT (e.g.: https://openwrt.org/toh/netgear/gs308t_1). Maybe there is potential to actually play games on that switch!



  • Manufacturers are allowed to add supplementary charging standards on top of USB-C PD

    Controversial opinion: I wish this wasn’t the case. So many different proprietary protocols, most of the time you’ll still need a specific adapter, and in some cases even a proprietary cable to utilize the full speed, and nowadays most devices come without the adapter.
    And there’s even PPS in the PD spec allowing to request for a specific voltage rather than something in an existing list.

    But I do also have some personal grievances here:

    1. Mi TurboCharge - This may be something based on PD, but still being something separate. I don’t know, but I do know it requires more pins than USB-A has. 5 pins. Somewhere I read this is connected to a CC pin in the USB-C connector. But no, they did not use USB-C, they used USB-A, with an extra pin. Only shortly before the phone died I finally figured out why it wasn’t charging as fast as expected - I wasn’t using their proprietary cable.

    2. My current phone’s interference (?) with Qualcomm QC 2.0 - Somehow when using a cable with non-perfect connection on QC-compatible adapters, when I move the USB-A connector, it starts triggering 12V mode until it finally shows overvoltage error and slows down to 7W. QC 2.0 is how my USB tester identifies it. This is a MediaTek-based device, so I don’t think it would support QC. The original adapter uses PD and some 11V 6A thing with unknown protocol. Perhaps that is where the problem originates, I don’t know what data it sends down. But testing with OTG adapter on the original brick it seems the protocol needs the extra pins of USB-C to work properly.

    I’ve had 3 phones that supported some fast charging, so far 2 of them made it into a confusing mess. Had they all used just PD it would have been a better experience.
