  • Hydrogen is troublesome as an energy storage. The roundtrip efficiency (electricity -> hydrogen -> electricity) is just… very not worthwhile compared to batteries. Then beyond efficiency there is still the question of “how do we store hydrogen safely?”

    Storing energy indefinitely is not a problem for electricity storage, since we are pretty much guaranteed to use the stored energy up in a single day.


  • It is all quite complicated.

    1. A renewable producer (e.g. solar panels) cannot produce energy 24/7. And when it produces energy, you are not guaranteed the production is stable.

    2. A consumer cannot consume energy 24/7. And when they consume energy, you are not guaranteed the consumption is stable.

    3. To make the issue worse, a producer may not be producing energy when the consumer wants it, and vice versa.

    4. Currently, energy storage is not widely installed. Hence any produced energy must be consumed at the same time.

    The factors above combined means that there will be a mismatch. If the production is too great, your electricity appliances will probably explode and whatnot. If the consumption is too great, you experience blackouts. Neither are desirable.

    Now consider there is a middleman. The grid. Producers sell energy to the grid. Consumers buy energy from the grid.

    At some point in time, due to the factors above, the grid will need (A) zero to negative prices to encourage consumers to buy & use more energy from it, and to encourage producers to produce & sell less energy to it. Or (B) increased prices to encourage consumers to buy & use less energy and producers to produce & sell more energy. A flat price is not realistic. (Residential users only have a flat rate because our demand patterns are more stable.)

    But due to the production patterns of renewable energy and consumption patterns of our society, there is a not-insignificant risk that renewable producers will consistently face scenario (A) above making it difficult to cover back the costs.

    Servo was an experimental ground for Mozilla in some ways (like testing out a new CSS engine and porting it back to Gecko if it works). So it’s quite normal for people to be unaware of it, it was not meant for the public.

    But later on it was abandoned by Mozilla and stuck in a limbo, until it got picked up by the Linux Foundation. Now it’s a standalone project and I wish them well. We really need a new FOSS web engine.




  • Yeah I get the display server part. What I meant was that 200% scaling gets you 1920x1080 logical resolution on HiDPI applications – LoDPI applications continue to be blurry just as if you set your actual resolution to 1080p, but HiDPI applications will enjoy the enhanced visual acuity.

    Even on smaller screens like the 14" ones, the quality of very high resolution (e.g. 4K) is still quite visible IMO, especially when it comes to text rendering. But it could very well just be my eyes.





  • The modern electronic devices are far more railroaded than it was back in the day tho.

    Want to download an application? There’s the App Store. No need to download random .exes from sketchy websites (and learn what a “computer virus” is the hard way)

    Downloaded a picture? It’s instantly inside your gallery. Back then we needed to find a folder called “Download” or “My Documents” using something called the Explorer!

    iPhone and Android made a lot of things dumber and easier to take in, but I feel like it had a detrimental effect on digital literacy.
