  • That may be true, but at least the genes for night owls are present in more people than the genes for early birds.

    So it should be expected that, regardless of phone usage, over half of the population will go to bed and wake up ~2-3h later than expected.

    If your timezone is closely aligned with the sun, that’d be 22:00-06:00 for early birds and 01:00-09:00 for night owls. But if your timezone isn’t, both of these times would shift around.

    For me personally, no matter when I go to bed, whether it’s 22:00 or 03:00, I always wake up precisely 09:30 without any alarm clock. But this also means if I have to wake up earlier, e.g. at 8am, I’ll be very tired and not well rested.

    It’s not just office, SH and many other parts of the German government have been slowly replacing the entire O365 suite with OpenDesk, which is an open source product based on Matrix, Jitsi, LibreOffice, and a few other tools.

    The goal is to have a fully integrated solution for calender, chat, calls, documents, cloud storage, etc.

    My employer is developing parts of that solution and we recently switched our internal communication over to it, and tbh, it’s working really well.

    Now is the perfect point in time to do it, with the GDPR ruling regarding O365 and Microsoft fumbling the migration between old teams and new teams.


  • You’re absolutely right on that count. If you switch fast enough, everything has a capacitance. That’s why with CMOS designs once you go above a few kHz you start worrying about fan out.

    It’s also why, once the ceiling is reached, everything starts using modulation tricks previously used in RF. Ethernet started with 1GbE, USB with 3.0, DSL did it from the start, with PCIe even gamers have probably seen eye diagrams in riser tests, and coax is the very definition of pushing RF over a wire.


  • Yes, of course there is error correction. Also, while the SSD is on power, it’ll constantly go through all data and fix the areas that are starting to deteriorate.

    But this does mean an SSD left without power will slowly lose data over months and years.

    This also means that writing data is much slower and the SSD can handle far fewer writes. But the tradeoff is that TLC and QLC SSDs can handle 2× and 4× more data than MLC SSDs for the same price.

    That’s why MLC SSDs are primarily used for professional use and TLC and QLC is primarily used for gamers.

    Some TLC and QLC SSDs even allow you to choose how much of the SSD should be used as SLC/MLC space (4× less data, 4× faster writes, 4× more endurance) and which part should be used as TLC/QLC (4× more data, 4× slower changes, 4× less endurance).


  • SSDs aren’t just that simple. All of them have at least some SLC area, usually as cache, that’s in base 2. But the rest of the SSD can be SLC base 2, MLC base 4, TLC base 8 or even QLC base 16.

    And overall it’s still base 2 because each SSDs pretend one block of base 4 is just two blocks of base 2, and accordingly they pretend a block of base 16 is just 8 blocks of base 2 storage.

    In timekeeping, there are so called stratums to describe how correct a clock is.

    Stratum 0 is a physical process, an inherent property of the universe. An atomic clock would be stratum 0.

    Stratum 1 is a clock defined based on a stratum 0 clock. For example, GPS clocks are usually stratum 1, so are timeservers at universities with atomic clocks.

    Stratum 2 is a clock defined based on a stratum 1 clock, for example, your router’s ntp server if it syncs its time based on gps or a university’s timeserver.

    So if we adopt this jargon for units:

    Meter is a stratum 1 unit, defined based on the stratum 0 properties of lightspeed and cesium resonance.

    Inch is a stratum 2 unit, defined based on the stratum 1 meter.








  • Considering that reading source code can take a long time

    You’ll get faster over time, until reading code is faster than reading documentation, as code will always represent what’s truly happening, while docs are frequently outdated.

    In a language the user isn’t familiar with

    If you’re not that familiar with the language, it’s likely you won’t be contributing to the project. Open source projects usually to have quite limited resources, so they tend to optimize docs and dev UX for people who are likely to contribute.




  • The UK spent decades convincing everyone that all bad decisions are made by the EU and all good decisions are made by Westminster. That’s the first mistake.

    If the UK had properly educated its citizens about what the EU actually was and did, no remain campaign would’ve been necessary whatsoever. But it was politically convenient to have a scapegoat.

    And let’s be honest, remain aka “remoaners” had a ton of arguments all the time. But brexiteers just wanted to enter the magical land where the UK still mattered and they’d eat their cake and have it still.


  • If you actually calculate the maximum speed at which information can travel before causing paradoxes, in some situations it could safely exceed c.

    For two observers who are not in motion relative to each other, information could be transmitted instantly, regardless of the distance, without causing a paradox.

    The faster the observers are traveling relatively to each other, the slower information would have to travel to avoid causing paradoxes.

    More interestingly, this maximum paradox-free speed correlates with the time and space dilation caused by the observers’ motion.

    From your own reference frame, another person is moving at a speed of v*c. The maximum speed at which you could send a message to that observer, without causing a paradox, looks something like c/sqrt(v) (very simplified).
