i've never heard of anyone using an anti-virus with linux, abstractly you could write one though.
On my antergros install Firefox is fucked up, all of the dialogue boxes and text bars don't display anything, just showing the buttons and things that are normally there, making it pretty much unusable. This happens on GNU/icecat as well and I don't know what's causing it that isn't present in KDE and XFCE (using MATE)
pic?

Clam already exists and saves writing one. Most of the time, not needed though.

Most of the time, these problems arise from a lack of updates, using insecure software, and accessing content using outdated software. Most of the time. Certainly not all the time.
But for the ordinary user, having your entire OS and all applications on it be updated on a daily basis is far better protection than what most anti malware software provides. That, and a simple but proper firewall setup. The latter is kind of lacking, but so long as you're behind a firewall, it's probably fine.

Also is firefox the best browser on Mint?[/QUOTE]
You don't really need an anti-virus for Linux. For Mac and Windows, yeah, but Linux has such a minute user base in comparison to the big OS's. As for browsers, just choose whichever you like, Chrome's available for Linux too

You're not right though. Maybe the desktop user base is small compared to desktop user base of other systems, but the server part is really massive. And under attack every single second as well.
I'm not saying you need an anti virus for any platform, but you need something to properly filter and block malicious transmissions, that keeps itself up to date every day. If that's IDS, Anti virus, or some other fancy firewall solution, doesn't matter. What matters is that you've got protection. Running a Linux-based system doesn't do that on it's own. Nor is that the case for an OSX/macOS or Windows-based experience. It just happens that certain design decisions about the Linux kernel and the Unix filesystem are pretty darn good, in regards to security.
Some auditing people at work told us we need an antivirus for our AIX machines for compliance, and we laughed them out of town, right before explaining why 1. its a silly idea, and 2. it doesnt even exist.
I would definitely suggest having a firewall, gufw is a good option that is quite easy to use.
Keeping your system up to date and using common sense is enough to keep you safe.

FTFY.
Here I was wondering why bash was mangling the prompt with wide characters in a path until I noticed that it happened with zsh too and only with PuTTY. Why can't unicode [I]just work[/I] on Windows like it does on Linux.
I can't even get unicode to work on windows offline on conemu even following [URL="https://conemu.github.io/en/UnicodeSupport.html#"]this [/URL] guide

I'm honestly not sure that bug is severe enough to even qualify for a severity rating.
It crashes the service but it's automatically restarted on the next query, and there's no possibility of RCE.
Configuring an Arch install on software RAID via KVM over IP was an enjoyable experience apart from IPv6. Less enjoyable was fighting with the installer that comes with CentOS to try to get it to partition shit correctly for half a day before giving up and accepting that Arch was the solution.
Not sure if I was just doing it wrong for 3 hours straight or does systemd-networkd not support DHCPv6 configured through a static address + UUID? It alone failed to do anything helpful, launching dhclient to get a lease would take out DNS until systemd-networkd was restarted, then IPv6 would work until the lease ran out. Works fine with network manager though so all good in the end.

The centos installer is awful if you're trying to configure your own partitions. I've been fighting that myself the last few days so i feel your pain

CentOS 4.9 installer on an ia64 machine (using 4CDs) at 3 on a Monday morning.

I've never messed with multiple internal HDDs in Linux. How would they work? For instance, on my Windows machine C: is Windows drive and some program files, and my D: drive is more programs, mostly games, and media directories. How would a setup like that work under Linux where you want certain programs to live on certain drives? Would you have multiple /usr/bin directories? Multiple /home directories?

Depends, a typical Linux setup allows you to mount drives to paths. C: could be mounted to '/', and D: could be mounted to '/home'. This is useful because if C: is an SSD, '/' is rarely written to and contains all your application data, while '/home' is just all your movies and stuff.
You can imagine the Linux file system as an upside-down tree with a bunch of drives hanging from the branches as ornaments. The trunk is labeled '/' and there's some branches '/home', '/var', etc.
However if you use something like an [url=https://wiki.archlinux.org/index.php/LVM]LVM[/url], then drives are completely abstracted to the point where your drives are just a fluid that adds to the volume of data you have access to, with some tools to keep fast files on ssds or whatever.
I should have been a bit more precise. What if I want some things like movies and music to be on one drive, but downloads and documents on another? How would the /home directory be handled? How would I install, say, applications to the SSD, and games to the HDD?

I agree with Poettering here, seems like such a non-issue.
Everyone hates on Poettering for various reasons, but they all seem to hate him for systemd or pulseaudio and try to find other reasons to get other people to hate him too.

If you find someone who dislikes Poettering and then ask them why, if they use the phrase "UNIX philosophy" then you can just entirely disregard their argument.
Well I have never heard of poettering before and have no idea about the controversy surrounding him.
But being able to easily crash such a widely used and integral part of a little of Unix systems seems important enough, even if all it is is a vector for a dos. That's bad enough sometimes and you'd certainly wanna know about it and patch it.

What service does crashing it deny when it restarts upon the next request? I've heard something about it losing a cache, but I'm not sure if one would gain anything from clearing its cache.

This depends entirely on your setup. If you install applications to / using software managers, and games are either steam or likewise, then for Steam, those games will be in your /home/username/.steam directory.
If you want things like movies and music to be on one drive, and downloads and documents on another, well there's multiple ways of doing this. The simplest way is to simply have another drive, and when opening it, make sure you have the rights to write to a directory on the drive, and then add your movies and music folders to it. Then you may simple create a shortcut or symlink, and place that in your home folder.

It's about making the server waste resources and thus either slowing it down significantly or bringing it to a complete halt (denial of service of eg a http server on the same server/thread).
Imagine spamming the exploitable request, constantly completely restarting systemd is probably an at least somewhat resource intensive operation. Even if that isn't significant, the cache (also probably) existed for a performance reason - if you constantly purge that cache resources are wasted on reading/computing what otherwise would have been just gotten from the cache
1. It's a small service that restarts extremely fast and causes no system usability problems when it crashes
2. It's a null pointer dereference that instantly crashes the application, there's no possibility of leveraging it into RCE
3. Points 1 and 2 mean it doesn't deserve a CVE
4. Points 1, 2 and 3 are something that the [B]Ubuntu Security Lead[/B] working [B]directly for Canonical Ltd.[/B] should fucking know
Is every Canonical employee required to be retarded or something?
It's good that it was fixed, but the entire system was designed so everything would stay stable and functional even if something like this happens.
