This is where an intel HD630 will beat an nVidia RTX2080

Participated in a development project where 4 real-time 1080p streams had to be re-encoded on a NUC sized device. It's obviously not possible on CPU in this case so GPU rendering was my first thought. The intel Iris GPU in the NUC handled 4 decoding and 4 encoding sessions without any issues flawlessly in real time.

Then I was playing around with an nVidia GT1030 in another machine which must be even better - one would thought - but it turned out that actually no, it doesn't have the necessary nvenc hardware. Then I found this: [https://developer.nvidia.com/video-encode-decode-gpu-support-matrix](https://developer.nvidia.com/video-encode-decode-gpu-support-matrix)

So GPU rendering (nvenc) is simply not possible on anything below the GTX1050 but the real surprise is that nVidia limits concurrent sessions on all consumer cards, be it a GTX1650 or an RTX2080. You'd think that it is because of the nvenc hw chip but if you look at the GTX1060 or the Titan V for example you see that it's not the case.

So what does it all mean?

To be fair the nvenc hardware is much faster on the nvidia cards compared to intel HD, so if you are going to encode a 2 hour movie it is the better choice. But if you'd like to use the GPU to encode 3-4 (or even more) real-time streams it's simply not possible even with the most powerful consumer nvidia card.

I tried it on my HTPC (i3-7100, HD630, 2x 4GB 2133 DDR4, Manjaro KDE and no dGPU) and it handled the 4 streams (screen capture via vaapi in this case) without any issues. Tried it with 5 concurrent captures as well but there were some frame drops on one of them due to the unusually high memory bandwith, the GPU was far from being overloaded (around 70% utilization). With 4 streams there were no drops, and power consumption was below 6W.

So this is where an HD630 will beat an RTX2080 :)

(on the terminal tab #1 is htop, tab #2 is intel gpu tools, tab #3-6 are the ffmpeg captures via vaapi, #6 being what has been uploaded).

Why don't Debian/Ubuntu default to debdelta?

So if I understood correctly, Fedora and OpenSUSE will normally only download those files of a package which actually changed. This implementation seems like a no-brainer to me, but debdelta as an apt equivalent is not only abandoned, it's not even in the Ubuntu repo.

Does anyone have the insight why that is?

BIOS Fast Boot option

I only use Arch Linux, no dual boot. Does Fast Boot option in BIOS settings still matter or it's only relevant for Windows?

mangl v1.0 - graphical man page viewer

Developer here. I have implemented some of the missing features and updated the software to where I consider it to be more or less complete. Now it includes a configuration file, Truetype font rendering, searching withing a page. Also some behavior quirks were ironed out etc.

The link is

[https://github.com/zigalenarcic/mangl](https://github.com/zigalenarcic/mangl)

It should compile pretty easily on any \*nix platform that has a C compiler, OpenGL, GLUT and Freetype libraries. Might need to do some tinkering in the Makefile on non-Linux/GNU systems like OpenBSD and macOS. Feel free to report any glitches and requests on the github page.

Linux flash based malware infects victims via an unknown vector

I would think this post would be pretty newsworthy in the linux world, since the delivery vector is unknown. https://www.reddit.com/r/linux/comments/dz2m9g/bleepingcomputercom_linux_windows_users_targeted/

https://www.bleepingcomputer.com/news/security/linux-windows-users-targeted-with-new-acbackdoor-malware/


> * Both variants share the same command and control (C2) server but the infection vectors they use to infect their victims are different: the Windows version is being pushed through malvertising with the help of the Fallout Exploit Kit while the Linux payload is dropped via a yet unknown delivery system. *

What was your first Linux application that you programmed?

Recently saw a Morse code app using ThinkPad LED indicator and thought that was neat. What ~~was the first~~ Linux app did you write or are currently working on? Let's hear about it! CLI or GUI based, all welcome!

Could I Dual Boot KDE NEON On A Windows Vista Laptop? And How?

Recently I got a new laptop that runs on windows vista. I was considering upgrading to windows 10 but I can't afford a brand new copy of windows 10 and usaully I take my computers into best buy so they can fix or upgrade my old conputers to windows 10. But they only fix computers with Windows 7 and up, and I really don't want to have
nto buy a copy of windows 7 dor them to upgrade it to 10 for free. So I considered installing linux on my laptop but I didn't want to lose my copy of Windows Vista because I think it's cool to own an old version of Windows. I'm very very new to this and I couldn't find any guides on how to dual boot KDE NEON on a Windows Vista bases computer. So I was just wondering if it is possible to dual boot KDRE NEON on ny Windows Vista laptop, and just how I could do that. If anybody can help message me or comment on this post please.

Recommend a laptop for a developer running Ubuntu?

Hi y'all,

It's about time for my next laptop. I've never been able to find a great solution for running Ubuntu on a laptop, so I thought I'd ask here for recommendations. Every laptop I've had so far has had a few hiccups running Ubuntu, nothing terrible but annoying. I'd be using it for software development, with maybe some gaming mixed in. No strict budget, but I'm looking for value without blowing the bank. Thanks!

Zorin OS

Why zorin os is collecting data every hours without informing about doing it so? Why people support distros like that ? If something malicious is installed from client/server it could collect more than just you could imagine.

Should Popular Linux distros like Ubuntu and Debian make zsh their default shell?

I use both macOS on my PC and Debian on a server to do some heavy code lifting. Recently macOS switched its default shell to zsh and it is miles better than bash. For what it’s worth, I am not a power user. I just write some simple shell noscripts to loop though files and run experiments, lots of `cd`ing and `ls`ing. I know that it is easy to change the shell to zsh but I was wondering what is preventing the large distros to make zsh the default shell.
