Android OS

What are the rules for using the linux kernel with a closed source proprietary OS?

What is the best open source OS/custom ROM to run on a rooted Samsung device?

Would this even still count as running linux?

Help me decide Linux vs Chrome OS

LTS distros and their "security updates"

Okay I'm not trying to throw shade at Ubuntu here, but I'm trying to understand. I've been using their LTS distros for quite a while under the guise that when a package gets a security update, they would backport that update into the repositories. However, from what I've seen lately, that's not really the case. The whole VLC fiasco was caused by Ubuntu 18.04 packaging an outdated version of libeml ([https://twitter.com/videolan/status/1153963312981389312](https://twitter.com/videolan/status/1153963312981389312)), and meanwhile I've had my own discoveries regarding 16.04 still carrying the OpenSSL 1.0 branch when the 1.1 branch has made some pretty serious security improvements ([https://github.com/openssl/openssl/pull/2083](https://github.com/openssl/openssl/pull/2083))

I mean, I kind of understand them not rushing to offer security updates for libeml to the LTS versions. It seems like a somewhat obscure library, it's in their 'universe' repository, and the specific flaw wasn't even discovered until recently; not to mention the flaw itself isn't really a huge deal. But on the other hand, how do they justify leaving OpenSSL security improvements out? I mean, that's a hugely ubiquitous piece of software, and its specifically geared *for* security purposes, yet they're still packaging a version which contains codes that the developers unanimously agreed needed to be stronger. Not compromised, but definitely weak.

I thought that the point of LTS versions was that you would lose out on "feature" updates to software, but "security" updates you'd still get. But how do they decide what merits a "security" update. Do they think that including a version of OpenSSL with the command-line encryption tool that follows best practices is just a new "feature" and not requisite to "security". I mean granted, there seems to be a lot of insinuation that OpenSSL's command-line encryption tool is somehow not intended for serious use, but that seems like a bit of a cop-out when the developers themselves chose to update it to reflect best practices. I guess the idea is that it's supposed to just be a demonstration of the OpenSSL toolkit for developers. Even in that capacity, it's just demonstrating how to use OpenSSL wrong. So why not update it? Especially since OpenSSL strives for legacy compatibility and is probably one of the least likely pieces of software to break other things when updated.

Anyway I'm not trying to be overly critical, but it's making me rethink this whole idea of LTS versions being kept secure, or if they're just fixed when they're broken. It seems a bit like re-actively throwing water on the fire once it's burning rather than pro-actively taking steps to remove any fuel sources before it breaks out.

What are the main differences between modern Centos and Ubuntu ? I know 1 is based on Debian and the other on Caos Linux but outside of that, Is it possible to learn your RHCE on Ubuntu or the syntax / commands are too different ?

**1)** What are the main differences between modern Centos and Ubuntu ? I know 1 is based on Debian and the other on Caos Linux but outside of that, Is it possible to learn your RHCE on Ubuntu or the syntax / commands are too different ?

**2)** The reason I ask this is because I am a WinAdmin and I want to learn Ubuntu Server and Centos etc been told Ubuntu is taking a large part of the pie now, it's popular

**3)** Do you feel Powershell on linux is at a point where it can replace Bash/Python or its just better off to learn Bash and later on Chef, Puppett, Ansible etc etc ? any senior Linux admin who knows PS well here ?

BeginnerQuestion : Is Linux safe enough for me to do banking and trading on it?

I know this sounds stupid or whatever, but I'm just wondering. I installed Deepin a while back and then on read on some forum where people said that it's run by a chinese community/group and they're watching your data...and then I uninstalled it. I know it's an OS same as Windows, but I do have this concern. I'm a little paranoid too because my paypal and bitcoin account did get hacked once(on windows). And I want to move to Linux for security reasons.

I hope you got the gist of what I"m trying to fucking say, sorry for being all over the place with this. Just want a little assurance and confirmation (and possibly, suggestions for distros).


Thanks!

Handling of public institution not offering Linux tools

Hey guys!

This is a non-technical question and I'm mainly interested in how others deal with situations like this:

So the thing is my insurance company has a web portal where one can handle a lot of the stuff, e.g. uploading pictures/scans of sick notices or certificates of enrolment for students and all sorts of stuffs that otherwise one would need to send by mail. So all in all really convenient. So far so good.

Now they implemented a "2FA" system where you have to authorize your devices once to be able to access certain functions in the web portal. The problem at hand here is that for authorizing a computer they provide an application but only for windows and macOS. So effectively I can no longer use this portal if I don't download their probably shitty mobile app, use WINE or boot windows in a VM or so.

For a lot of you folks out there I think it won't be the first time you can't use something because it's not supported but for me it's the first time. Even though it's nothing super important and there are ways around it, this sh\*t really grinds my gears. Same goes for (public) organisations not accepting/offering encrypted mail? Have you been excluded by some some-what-public organisation because you care about privacy and stuff? What are your thoughts on this?

**Just to be clear I'm not asking for help or workarounds, this was more supposed to be just an example I encountered. I am more interested in you opinions and thoughts about this general topic.**

EDIT: Mentioning WINE as known workaround and spelling.

Why so linux?

Hi everybody, I'm not used to do this but this is my fresh project that I started following a passion after 10+ years of hard work and study. If you want to give it a look you're welcome, and spread the word!

Dotfiles must go. Start the petition. One at a time.

My fellow Tuxmen, it is time we take back control of our home directory. It is time to get rid of the dotfile jungle that rules \~. I read an article somwhere a month or two ago, and then DistroTube covered it as well. I think instead of bemoaning about the issue, we should do something about it. The good thing is, Linux being open source, there is a real chance that the software developers might actually listen to the community. [I have already opened an issue in GitHub for VS Code](https://github.com/microsoft/vscode/issues/78026). Feel free to chime in.

Next up is Mozilla, for Thunderbird and Firefox. Does anyone know where I can report the issue? Or is social media the only way?

Should I use tlp on a brand new laptop?

I just got a Thinkpad T495 two weeks ago and am running Ubuntu 19.04. Basically, as I said in the noscript I'm wondering if I should run tlp to increase the battery life.

My question is, will the performance trade off (if there is one) be worth the increase in battery life? I'm not super familiar with tlp so I don't really know what it does.

Thanks.
