  • Public transit is common in my 3rd world country and I was surprised how more unsafe it feels in the US. My theory is that it is a by product of the car centric society. For one there is safety in numbers and because it is so underused any one person is more exposed. But also because almost the only people that take the public transit is people who cannot drive or be driven for some way or the other it inevitably have a bigger proportion of mentally unstable people for example.




  • There’s nothing to indicate the human brain can’t be implemented in a Turing machine too.

    That is not true, this is a research branch from computer science and math, it is called Computability theory, it deals with the limits of expressiveness for different types of theoretical machines and expressions, and the most expressive of all is the Turing machine, and a Turing machine cannot do some stuff, the classic example is the Halting problem, a computer cannot definitely say if an algorithm ever stops (mathematica proven that it cannot do it), but a human can do so quite easily.

    One may think that maybe a Turing Machine cannot do something but can simulate another machine that does, but that is also proven to be impossible, it cannot simulate something more expressive than itself.


  • I will have to defend users here and blame AI scientist/developers together with the whole docker culture. The way they package and delivery software is just terrible. And even though pytourch has support for all GPU apis the devs seems to have a hard time adding this support. Granted, part of that is also on pytourch that for some reason Don’t seem to be able to make a unified release that supports all GPUs and then you need different versions and by default IIRC they default package only supprt CUDA and CPU.



  • It is worth pointing out that the only reason docx support is lackluster is because of active efforts from MS to undermine third party support. It is a interesting story actually, but I don’t recall exactly, but it goes like this, there was some regulatory push to open formats and MS undermined this by creating and making the docx (and all other *x family) open but make it so convoluted and unnecessarily difficult. If I am not mistaken they even keep unnecessarily updating and changing it so third party is always lagging behind in support and the cherry on top that MS don’t correctly implement its own format on purpose so the files are effectively broken for anyone that follows the spec to a T.





  • I “love” when the wrong technology is applied.

    On the the dawn of the smartphones Mozilla tried to enter the space with an FirefoxOS and the pitch was that every app was just a website just more tightly integrated with the phone. The problem is that all the web stack is wonderfully resource hog and at the time phones were super underpowered running websites were not optimized in a browser that were not as optimized as today. So it was a terrible choice for the time being.

    Other good one was Android early days. They choose Java as the default app environment and development. It kinda makes sense to use it if you want the same program to run on different platforms, the problem, again, it runs worst and with the underpowered devices of the time everything was a slog. And they doubled down on the mistake by using a garbage collector that doubled the memory usage of every app. The cherry on top, at least in hindsight is that arm was and still is the de facto Android plataform, greatly disminishing the advantage of using Java/JVM. And today Google enabled apps with native code optimized for specific plataforms, but everyone only care about ARM so of you try to run Android like in an Intel laptop a lot of apps are not compatible.

    End of rant.






  • The biggest hurdle for a Linux phone is proprietary drivers. On a PC you can swap parts, you can add a USB wifi or sound card on a laptop, but on a phone you are kinda stuck with all the stuff on the phone, so the problem with binary blobs is so much worse, and untill we don’t have at least the full drivers source or datasheet as an normal part of phone releases it will always be an impossible to win catch-up race.

    At least phones are not getting that much better anymore so is starting to be feasible to floss hackers to fully port Linux to some phones in time for them to still be usable (battery problems a part).
