notcurses 2.1.2 employs sexblitter by default where supported, multithreaded nclsm

hello there, penguinistas! i've posted here about my Notcurses project (github) before, and if you're uninterested in the Local Group's most powerful TUI/character graphics library, go ahead and move on. otherwise, azaelia and i hope you enjoy the 2.1.2 hype video, showcasing my new Unicode 13-based "sexblitter":

​

clockwise from upper left: ASCII, halfblocks, sexblitter, quadblitter

sexblitter uses the Symbols for Legacy Computing introduced in Unicode 13 to map a 3x2 pixel region to a single ccharacter cell. the improvement in resolution is noticeable, especially over the halfblock solution used by e.g. mpv's TCT output driver and viu and even over notcurses's own quadblitter. if you're not looking for a full-screen render, sexblitter still improves image quality in whatever portion of the screen you use, or allows a smaller region for images which fit wholly within the screen.

of course, notcurses is a TUI library, not just a flashy image/video renderer, and 2.1.2 introduces a new progress bar widget, accelerates rasterization via use of the `hpa` control sequence, and introduces a multithreaded `ncls` that must be seen to be believed:

​

1471 images rendered with the highest quality. Video is not accelerated. w00t!

take a look at one of the growing number of tools making use of notcurses, or better yet go write your own! available under the Apache-2.0 license.

not bad for a year's work, if i do say so myself =\]. happy 2021, hax0rs!

Garuda Linux

Anyone here try Garuda Linux? I'm currently giving it a spin and it's pretty freaking awesome! Has to be one of the prettiest looking distros ever, also, I've had absolutely zero issues with it. It seems like no matter what distro I try, theres always an issue with it, weather it be random crashes and stuff not working. Garuda so far has been working perfectly. Highly recommended

Should I switch to a tiling window manager?

I am currently on gnome. I added conky to the startup and I guess that messed something up. I only had access to the terminal until I deleted conky from startup. It was a brief moment, but I considered switching to something like Bspwm or Xmonad and still having that urge sorta thing. Should I consider switching or just keep using gnome?

I can't seem to decide if I want to join in

Hi! I've tried multiple times to go into linux in the past. Now it has been 4 years that I haven't touched a linux distro and the only thing that was keeping me of switching to linux was gaming. I was owning to many games that were not supported by linux to go with it. Wierdly, Linux have always been a fun experience for me but it was lacking in the game aspect. Did it change recently. I keep receiving "gaming in linux is now differant" videos on youtube recommendation.

GTK 4 and toolbars?

Anyone knows if is it true thaT GTK 4 won't support toolbars? (Rumor I head that the Gnome team (who basically handle GTK exclusively) consider toolbars "outdated technology that should be removed"). Won't that mean it basically eliminates all GTK DEs except Gnome? Unless Mate / Xfce / Cinnamon decides to fork GTK 3 and stay on it?

Linux jobs

Hey I’m an average American who has used multiple Linux distros over the years and troubleshot many problems I think we all have faced. I get that in the eyes of the average older person this would seem like wizardry when to us it’s basically 10 minutes of googling. Wondering if anyone has turned this into any sort of job cause I feel like I know more about Linux than 99% of the population (and that means I’m in the bottom 1% of people on here)

Unable to Download anything on Linux Mint after a fresh restart. Help

So I’ve had Mint for awhile now and it’s been amazing until recently.

It likes to freeze up from time to time, like twice a week and I have to constantly run (fsck /dev/mapper/etc—vg-root -y) this fixes the issue until
The next time it freezes. Anyways that’s a separate issue that maybe contributes to this one.

Now I’ve just started up and went to download some music. I get an error code as I press download. The code reads,
“could not be saved because disk folder or file is write protected”
It’s almost like I’ve lost access to controlling my files or something.

I’ve read it could be hardware/hard drive related but it’s a powerful asus laptop that runs flawlessly in my opinion. I don’t care to lose any files as I could just transfer them but I really rather avoid that hassle. Hopefully there’s a fix to this that any of you advanced users may know?

Why do people want to make Linux popular?

I built my first Linux PC about a year ago. So far setting it up to work optimally with my hardware has been the most painful experience because all the software repositories that are in guides to use change locations. IDK Linux I wanted to learn but I don't want to have to scour the internet for information just to make my programs work and for the desktop to remain stable. All my hardware seems to be buggy with Linux half my games have to be played through lutris or proton. I actually can't stand this it's like vista all over again why would anyone recommend this to someone like they did to me. You have to be able to use terminal nearly every applet breaks over time and u either have to update your dependencies or install a new edition of the OS.

Only thing that really bugs me about Linux is u can try to force something and some other setting overrides it. Out of the box 19.2 cinnamon was buggy and I actually had to mess with terminal to even make the splash screen work.

CLI browser with built in ASCII image display

Hi, I posting here because of the community size.
I know W3M able to display images on X11, and I know Browsh able to display everything in ascii.
But I still love links and all fork and I don't mind to not download automatically the pictures. So please share if you know any links fork that support a built in ASCII image display support. I thinking about something like links, but you could (by a short-key) open the images via chafa (or some similar) without storing on disk. I know it is a special need, but I wish to not make another unnecessary "WHEEL" if it's already developed.

Installing Jack Audio On Chromebook / Linux

I'm dumb, and I don't know how to install anything on linux. Can someone help me with installing Jackaudio, I got the tar.gz to a folder and idk what to do now. I've attempted to understand the readme files and what not, but my brain can't comprehend the stuff that it's saying.

Or if this isn't possible on the Chromebook Linux thingy for some reason, just say.

What exactly is expected of a package maintainer?

I assume if it would just be "build a package and add it to the repo", and additional updating, more people would do it. Does maintainership require technical knowledge, like the ability to audit the code? Do distros require you to register somewhere officially or something? I'd like to hear your experiences with various projects.

Stripe Size and Speed of XFS on HW RAID10

I am running HW RAID using an Areca 1216-4i controller with 4 x 16 TB hard drives in RAID10 to give about 32 TB of storage.

System will be used by 3 users for CAD design of integrated circuits.

Most of the files will be cad tools and libraries but they are running simulations and drawing integrated circuits which will generate many files

The Areca gui reports stripe size: 128 kB and block size 512 B.

I already set up an XFS partition using default parameters. fdisk-l just shows sector size and i/o size 512 b.

Questions:

Does the 1216 controller export stripe info so that mkfs.xfs picked it up during file system creation?

How can I tell what su and sw values were used if any in the creation of the xfs file system?

If values in file system I created were wrong then how much will this impact performance?

If I remake the fs then what do I specify for su and sw?

From Redhat docs I think

su=128k. (From raid controller stripe value)
sw=2 (4 disks in raid 10 so 2 data disks)

Is there a better stripe value to use for the raid controller?
