  • Yes, it is still a quartz watch. The oscillator is still a quartz oscillator. However the mechanism which advances the second hand is replaced with onethat does not need to tick.

    The kind of quartz watch is no longer a ticking quartz watch, it is a non-ticking quartz watch.

    As for the specific wording of the article, I would assume the authoris not fully versed in partsof quartz watches, and does not know that the oscillator which keeps time is different from the stepping motor which moves the hands.

    This invention targets only replacing the stepping motor, not the oscillator.






  • Ok, heres my run down:

    Nix is a package manager with the goal of making it so that when you install a package at a version, you always get the same thing.

    But isn’t that how all package managers work? Not at all. Most software requires other software to work (dependancies). Those dependencies also have dependencies, and so on. If a version of the dependency changes between installs, your package works differently. So Nix forces the package to specify what version of the dependency to use.

    But version numbers are pretty wishy-washy, so nix actually requires git commits. This is good, since it turns out, the compiler and libraries used to build the software are dependencies, too. Building with a different compiler can change the way the package works. So Nix forces the package to specify how to build it also.

    So Nix is a package manager where each version of a package is built against a known compiler, and comes bundled with a known set of dependencies.

    This allows some cool things, like generations. Change your list of installed packages (or configuratian, it handles that too), nix can save the old config and instantly go back to it. No more bricked linux install (if it can get past the bootloader). Also lets you do os-level per-directory installs. Have two projects that each need a different version of c compiler or postgres? Nix makes that easy. Want to make sure all dev machines in your project have the same python version? Just check in the config.








  • Both styles have advantages and disadvantages. Fully procedural code actually breaks down in readability after a certain length, some poeple suggest 100 or maybe 200 lines, depending on how much is going on in the function.

    Blanket maxims tend to to have large spaces where they don’t apply.

    Additionally, the place where the code on the right is more likely to cause bugs and maintainability issues is the mutation of the pizza argument in the functions. Argument mutation is important for execution time and memory performance, but is also a strong source of bugs, and should be considered carefully in each situation. We don’t know what the requirements for this code are, but in general we should recomend against universal use of argument mutation (and mutability in general).








  • I feel like, with this reply, you are willfully glossing over my point. The issue at hand is that open source software is short on the ux design expertise. My claim is that by centering the programing expertise, and in fact by not going out of the way to be inviting to the non-programming expertise, open source projects are self-perpetuating these cycles.

    We can find ways to invite good designers in, or we can continue with the “sufficient” design ost projects currently have.

    I’m happy if people have ather strategies for overcoming the current problem, but the current aproach is not doing it
