  • ctr1@fl0w.cctoLinux@lemmy.mlIs anyone using awk?

    Yes! Awk is great, I use it all the time for text processing problems that are beyond the scope of normal filters but aren’t worth writing a whole program for. It’s pretty versatile, and you can split expressions up and chain them together when they get too complicated. Try piping the output into sh sometime. It can be messy though and my awk programs tend to be write-only

    I usually use Awk to do the heavy lifting within my Bash scripts (e.g. arg parsing, filtering, stream transformation), or I’ll embed a Node.JS script for anything more advanced. In some cases, I’ll use eval to process generated bash syntax, or I’ll pipe into sh (which can be a good way to set up multiprocessing). I’ve also wanted to try zx, but I generally just stick to inlining since it saves a dependency.



  • If you’re willing to spend the time to learn how to write custom policies, SELinux can be used for this, to some extent. It’s highly customizable and can sandbox your apps, but the process of doing so is quite complicated. I wrote a small guide on custom policy management on Gentoo in another comment if you’re interested.

    There’s also apparently a “sandbox” feature, but I don’t know much about it. I just write my own policies and make them as strict as possible.

    As an example, my web browser can’t access my home directory or anything except its own directories, and nobody (including my own user), except root and a few select processes (gpg, gpg-agent, git, pass) can access my gnupg directory.

    This only covers security/permissions, and doesn’t include many of the other benefits of containerization or isolation. You could also try KVM with libvirt and Gentoo VMs; that works pretty well (despite update times) and I did that for a while with some success.










  • Try going down the page and looking for the categories with more than a few bits of identifying information. I’m running LibreWolf with just uBlock Origin and Dark Reader (which I don’t think influences results) and I’m able to get nearly-unique, instead of unique (but I do get unique on default settings). TBB gets non-unique, which is a good set of results to compare to.

    In my case I noticed that my fonts were really unique so I set browser.display.use_document_fonts = 0. Also I use my WM to set my page resolution to 1920x1080, which seems to have a better fingerprint than the default LibreWolf floating resolution of 1600x900 (and even the letterboxing resolutions, from what I can tell).

    I just spent some time testing again and checking for anything else. RFP does force a generic user agent, but unfortunately it keeps the version information and I can’t figure out how to change it with RFP on. Would be nice to set it to the ESR version used by TBB (which has lower bits), but I’m not sure if that would lead to a more unique fingerprint (if, say, a feature was detected that is available in later versions but not ESR).

    Edit: just tried Mullvad browser, and it’s non-unique! Might be the best option.



  • ctr1@fl0w.cctoLinux@lemmy.mlIs gentoo a good choice?

    Yes! Depending on how much time you want to spend figuring things out… there is a learning curve, but the documentation is quite extensive. And you do learn a lot about Linux by diving in. The compile times aren’t really an issue today if you have decent hardware- I run it at home and on all of my servers (some of them not very powerful). You can do other things while it’s compiling.

    It’s great if you want to customize everything and learn how your system works, or are interested in optimizing everything for your specific CPU architecture. There are a few pitfalls (especially when learning), but I’ve generally been able to learn how to fix any issues as they arise.

    Also, the package availability is great. If you can’t find something in the gentoo repository or in an overlay, you can usually find its dependencies and build it yourself.
