  • Dude, you don’t just pump the combustion result through your house.

    I wrote “LPG or natural gas could certainly contribute to humidity levels in some cases,” and was thinking specifically of non-vented gas heaters, which are very common in my experience, and are in some cases used for whole-house heating where there isn’t a central air circulation system. In this case, the combustion result is literally released into the house.

    While this thread is about gas heating, the article is about gas cooking stoves, which in most cases can be vented only at most very poorly (with a range hood), so the risk being dicussed is literally a result of releasing the combustion result into your house.



  • [Can] a patch can kind of be like a hook?

    In the free software world, a patch usually describes a file that lists lines to be added to or removed from another file (or multiple files). The most common use for this is probably with actual source code.

    Binary (non-text) patches are also possible, and in Windows a software bug-fix “patch” would likely be mostly binary. In the free software world, it’s uncommon to use binary patches for updates; instead the source is patched (either in the main upstream project or by a distribution) and a new binary package is built and published.

    Where you create a config file that has symlinks to all the executables like you mentioned?

    I don’t really understand how those two questions relate, so I may not be able to give you a good answer. Often a configuration file has a variable=value structure, but it would certainly possible to have a list of file paths in a configuration. However, this might instead be implemented as an actual directory (like ~/.config/app/pre-hook.d/) where each executable file in that directory is executed by the “pre” hook in the app. (Configuration directories often work very similarly also.)

    Whether the paths are symlinks is likely to be irrelevant, as this is more a filesystem level feature that would often be ignored entirely by the application.

    I hope this is helpful.


  • A hook is a mechanism for adding functionality at a certain point in a program’s normal flow. As a simple example, imagine a program that works by doing three things in order. It could have hooks that allow the user to add actions before or after any individual steps. Each possible point in the flow is a separate hook. One way to implement it is with a directory for each hook in the program’s configuration directory, where executables can be placed; the hook runs each executable in sorted order.

    I didn’t look up any of this, so it may not be the best explanation, but I hope it is helpful.













  • Look at non-multi-function “Enterprise” laser printers. They are completely different than the consumer grade garbage.

    I recommend an HP LaserJet Enterprise Mxxx printer, color or not, that is listed on the HPLIP All Supported Printer Models page.

    You can find lightly used, older model ones on Ebay, sometimes even with a full toner cartridge(s), for much less than new price.

    HP is still releasing firmware updates even for many older models, and the firmware is loaded with features (for example, if it is connected to your network, network printing works from Android and Apple phones without requiring any special apps). The firmware does not depend on any remote service.

    If you even need them, the Linux drivers are free and open source and packaged in Debian main (for example); your don’t have to install some weird closed source garbage that won’t work in a few years.

    People here are recommending Brother, but I don’t think they have free and open source drivers (think “nouveau vs. Nvidia”). Am I incorrect about that? In my experience, this can become a significant problem as software moves forward but the company does not continue to support their Linux binary driver.
