I have a few different Linksys WRT54G routers and I've installed DD-WRT - build number 44715 - on them. However, this build appears to have been made in 2020. So, I was wondering if there's a more modern version of dd-wrt for this router. If not, is it possible for me to compile the latest version of OpenWRT for these routers which have 4 MB of flash and 16 MB of RAM?

I've found 2 vintage desktops from around the 2000's era. One already had a broken power supply that won't even turn on (and thankfully didn't break anything else). The other desktop had a working ATX PSU, but it just blew out a few days ago. The PSU is an Elitech LC-B450E and I believe it has 4 molex connectors.

Now, I was wondering, would it be possible to repair the PSU (not that I would do that myself because I don't even know how to solder)? If not, would it be possible to get a relatively new one that's compatible?

I was thinking of getting a wifi card like that, but can't seem to find any.

I am running Linux on my macbook pro and it has a Broadcom BCM4360 wifi card. Problem is that the driver for it is proprietary (or more accurately, mostly proprietary with some of the source code available), quite outdated, and I couldn’t get it to work with Linux kernel v6.9.5.

I am running Gentoo Linux on my macbook with a custom kernel. I previously had wifi working, but then I reinstalled Gentoo (because I wanted to do full disk encryption), copied over the kernel config file from my previous install (which I knew had working wifi), migrated it to a newer kernel version (plus added support for full disk encryption) and now the wifi drivers won’t even compile.

So, I was thinking of replacing the current wifi card with something that has modern and open-source drivers for it. Is it possible to do that on a Macbook pro 11,2 (Retina, 15-inch, Late 2013)? If so, are there any compatible wifi cards with open source drivers for Linux?

I want to install a (or build my own) custom AOSP-based OS on my Samsung Galaxy J3 SM-J337W that has microG instead of the proprietary Google Play Services. Please forgive me if I'm doing something stupid: I'm a complete noob with this.

So, the first thing I did was check and see if my device is officially supported by ROMs like LineageOS and I couldn't find anything. Not only that but my device isn't supported by TWRP.

Next, I've done a bit of further research and read about GSI ROMs and Project Treble. The Treble Info app says that my smartphone is Project Treble compatible with the following requirements:

• VNDK version: 28 (lite mode)
• System as Root: disabled
• Manifest location: Modern
• CPU architecture: ARM32
• Binder architecture: 64-bit However, the only a64 non-SaR GSI images that I could find are some of Andy Yan's builds of LineageOS 16 and 17 and they do not have microG installed. Plus, I just don't want to install any malware-infested OS from some random Joe.

I've been thinking of building my own custom ROM or GSI. However, compiling AOSP would take a long time.

Has anybody ever managed to install a custom OS on the Samsung Galaxy J3 SM-J337W?

I have a Samsung Galaxy J3 2018 (model number SM-J337W) on which I want to install my own custom AOSP ROM (because I don't want Google or Samsung to spy on me, I'm stuck with my current phone, and my phone is not supported by LineageOS, GrapheneOS, or CalyxOS). I have managed to install ADB for Linux and unlock the bootloader, but I can't download any TWRP binaries because my phone is not on the list of officially supported devices. I believe i've found the source code for TWRP on this Github page: https://github.com/minimal-manifest-twrp/platform_manifest_twrp_omni. However, I'm not really sure how to build it. According to the code lines bellow, I believe it requires some kind of device number or code:

cd <source-dir>; export ALLOW_MISSING_DEPENDENCIES=true; . build/envsetup.sh; lunch omni_<device>-eng; mka recoveryimage

or if I'm not using a recovery partition:

cd <source-dir>; export ALLOW_MISSING_DEPENDENCIES=true; . build/envsetup.sh; lunch omni_<device>-eng; mka bootimage

Also, I am not sure whether or not if my device uses a recovery partition or not. How do I find that out on my specific device?

Also, when I open up AIDA64, then go to System -> Device, it says j3topltecs. Should I use that for my device number/code?

Also, please keep in mind that this is my very first attempt at rooting any Android smartphone so sorry if I sound like an idiot noob. I also use Linux and don't have Windows installed.

Also, is there any way I could tell lunch (or whatever tool does the compiling) to use only a specific number of threads because if it starts compiling using all 8 threads then my PC will definitely overheat.

PS. Do I even really need TWRP? Has anyone ever managed to install a custom ROM on this specific device?

I have a Samsung Galaxy J3 (2018) smartphone which currently has the stock Samsung Android OS installed on it. I wanted to install an Android "distro" that doesn't spy on me, like Graphene OS, but I couldn't find a ROM for it. Since I would probably need to compile AOSP from source code anyways, I though, why not install Gentoo on my smartphone (doing the compilation on a more powerful computer using distcc). I have already installed Gentoo on both my laptop and desktop from a stage3 tarball and I'm loving it, so I guess doing the same on my smartphone wouldn't be too hard.

Now, the problem is that I need to use a few apps that are not available on Linux, like the proprietary app that I use to pay for my bus tickets. How well does waydroid work?

I am currently a Computer Science student in university who really loves Linux and FOSS software, hates it when governments and corporations spy on people, and would probably rather have a job that brings meaning and benefits society than one that has a high paycheck (although I do recognize that I also need to have enough money for food, housing, .etc). I also watch Scammer Payback and Jim Browning and I love what they're doing, but I don't know if I could turn that into a real job.

I've thought of doing pen testing (later on in my career), but I've come to realize that it is better if users just started using privacy-respecting FOSS software like Signal, because if you give a hacker enough time, patience, and the right resources, they could hack into anything. Although for something like banks, I'd maybe be ok working there, as everybody still needs them and they're not going away any time soon.

I also need something that I could get into fresh out of university or even as an internship or co-op.

Am I being too pessimistic? What would you suggest me to do? Feel free to challenge my views on life.
