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?

I'm on the fence again of going back to W10 full time - and feeling tired

I'm a pro photographer and love Linux, love open source world, community, everything. I love using my KDE, love doing stuff there, tweaking things, reaching out. Love the apps, love knowing that my system is working for me and not for some nasty corp. out there. Love to help wherever I can or file a suggestion or bug report.

BUT - I miss my work tools. And my work tools are Photoshop and Lightroom. Mostly a PS.

I have tried. Really, really tried to find a substitute. I made GIMP to look and feel like my PS used to - all shortcuts, menu positions, windows. Except Actions, whatever GIMP offered, I used. But no matter what, its clunky interface and slowness (compared to what I've used to) made editing images a tiring experience. I have to edit a lot of images and all are super big ones (30mpx) 16 bit files.

Then I tried Krita. Super fast moving, super PS-like interface and shortcuts, many many pro tools for raster images. Big kudos to Krita and its team - you guys rock! But actually changing something within a 30mpix image is slow. Firing up Curves takes a few seconds, changing Curves takes another. I started longing for speed - again!

Then I installed PS under Virtualbox - no 3D, very limited amount of VRAM (256mb out of 8gb!), limited memory and cpu usage. And you know what? It eats both Krita and GIMP combined as far as the speed goes! :( Like there's no comparison - not only I have my Actions, but doing stuff there is an instant. All that in a virtual environment with at least 60% less hardware and no GPU acceleration!

So I reached the point - again - should I stay or should I go? This is my job. I can hate Adobe or Microsoft as much as I can but I am forced to work there as there is NO good enough substitute for my needs in FOSS.

I could keep working in virtualbox, under virtual environment. But why waste my super-current hardware? Why using like 40% of it? PS is fast and all, but could be way faster, as it is not using any of my GPU. 3D is not working nicely under virtualbox so I have to keep that disabled too.

I'm very sad about it and frankly, tired of all those transitions I did over 2 decades... I finally thought I found it, this is it. I deleted all win partitions, I made only ext3 file systems... but maybe it's time again to go back until this lousy company starts making PS&LR linux ports.

Ubuntu not upgrading 18.04 to 20.04

An unresolvable problem occurred while calculating the upgrade.

This was likely caused by: * Unofficial software packages not provided by Ubuntu Please use the tool 'ppa-purge' from the ppa-purge package to remove software from a Launchpad PPA and try the upgrade again.

If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details about the upgrade. Specifically, look at 'main.log' and 'apt.log'

​

I tried most of the methods available on google but couldn't figure out the problem.

Any resources for building an OS from the linux kernel up?

Hi I was wondering if there is any guides/resources on how to make an operating system on top of the kernel and also how the Kernel works, I have a lot of time on my hands and I thought it would try to learn something new! Any help would be very appreciated.

Pure Minecraft distro

So this sounds weird buut, I have a plan to make a distro with the sole purpose of just playing Minecraft, I was wondering if anyone had any ideas on what the minimum resources the computer would need to just run Minecraft. I know you need like java and a desktop environment, but I want to cut all the fluff. I was also wondering how I might customize a distro like Debian to have my requirements, and possibly distribute this Distro. Any help would be appreciated!!

Is there any good Conway's Life for xscreensaver?

cloudlife does not allow you to run a normal game of Life.

Googling found this and this which both have weird bugs and limits. For LifeSaver, the scale option seems to draw 1/N as many pixels, as if it was going to scale, but it won't actually scale for me.

Interesting find

Hey everyone! I just started learning linux and how the operating system works (for reference, I started learning a few days ago).

I'm currently working with a program that was recommended to me by a friend who has known about linux for some time. The program is called overthewire.org, and it's less of a program and more of a terminal based learning game (check it out).

I started experimenting with the windows cmd prompt, which is basically a primitive version of the linux terminal. Using some of my knowledge from the terminal coding game, I tried to get the program running on cmd.

Surprisingly enough, the program ran pretty well up until I had to switch levels, I made sure I had the proper code to advance to the next level, but even after some testing, and revision, cmd still denied access to the next level in the program! I obviously know that the linux terminal works differently than windows cmd prompt, but I still imagined that the program would fail at much farther ahead.

I figure windows puts a lock on the cmd prompt so you can't do too much with it. Unlike linux, windows just has the cmd prompt as a feature, just to say it's there, but linux pretty much runs on the terminal.

Just an interesting find, I thought I should share it!

ps: I use the latest version of ubuntu for linux, and I prefer linux mint, but I'm open to trying the other versions.

Fusion 360 alternative

Hey guys, I've recently decided to drop W (IT Tech and GNU/Linux nerd for at least 5-6 years)but this means I need a cad software. I've used fusion 360 since I only need it for 3D printing.
I thought about blender at first but quickly realised that for functional parts it's not the best. Also gave a try at freecad but doesn't fit me.

Any sync'ed monitor backlight out there working also on linux (ubuntu)?

As noscriptd, since I started working from home recently, I'd like to improve my working spot by adding some monitor backlight

I read somewhere that it helps against the eye strain and since I work also at very late hours (especially when the kids are in bed) I'd like to preserve my eyes as much as possible.

However, given I spend half of my time on Ubuntu, I'm looking for something compatible also for Linux and I'd like to have it in sync with the current image visible on monitor (there are static simple backlights as well)

Any tips, guys?

ZombieTrackerGPS 1.05

Version 1.05 of ZombieTrackerGPS (Winterbike Edition) has been released, with several new features based on user requests and feedback.

ZTGPS is a Linux+KDE native PIM application satisfying the same purpose as Garmin's "BaseCamp" software, which does not run on Linux. ZTGPS provides sophisticated query and sorting capabilities for GPS tracks. It is targeted at cyclists, runners, hikers, light vehicle use, and anyone collecting GPS tracks from handheld units, particularly if you prefer data storage on your own computer to cloud based storage. A feature denoscription and FAQ is available on the web site below. Binary packages for several popular distros are available under the Downloads tab.

Recent additions include live capture from the Linux GPS daemon, support for GPX waypoint import, export, and management with auto-symbol selection from the US National Park Service map symbol set, localization support, and a more efficient internal point storage for 35-40% smaller memory and disk footprint for the same data. Other recent changes are below.

Version 1.05

Support for waypoints. There is a new Waypoint Pane, and they can be imported from and exported to GPX files. If the waypoint supplies a symbol, ZTGPS will attempt to find a matching waypoint icon from its builtin set. Otherwise, this can be done manually with the "Set Icon..." context menu. See the in-program documentation page for the Waypoint Pane for details.
The "Export All Tracks" option in the export dialog is fixed.
The program crash on exit if a secondary window had UI focus is fixed.
The US National Park Sevice (USNPS) map symbols, and some in similar style, are now available for waypoints, view preset icons, or other purposes.
If autosave on exit fails, the exit is aborted, to allow a chance to manually save to another path.
Numbered backup files are now saved at most once per session, rather than once per save.
Internal track point storage is more memory efficient by 40%, and on-disk track files are about 30% smaller.
Added Cache tag icon for tracks related to geocaching.
Sessions are now locked to prevent accidental conflicts with another running ZTGPS.
Previous .png point icons are replaced by .noscript's, which scale better. Old saves will be autoconverted on load.
Secondary window noscript can now be customized from their tab bar's context menu. This is useful with KDE's task bar.
WinterBike transport category added, with higher rolling resistance than other types of bicycles. There is more per-tire-model variance here, so the exact values can be adjusted for your situation in the Tags tab of the Settings dialog.
Quoted strings in queries now work correctly.
Fixed crash in the KML format importer on some files.
"~" is now a synonym for the regex operator '=~' in queries, "&&" for "&", and "||" for "|".
Application focus is no longer stolen upon program launch.
Added --private-session command line option to disable saves. Useful for temporary sessions along with --conf.
Undoing a UI change (e.g, adding or removing a tab) no longer clears the undo stack, and is available for redo.
The project structure has changed. If you build from source, it's best to use a fresh tree. See updated BUILDING.

Version 1.04

Added live capture support from GPSD. See the new section in the "Importing GPS Data / Live Capture (GPSD)" section of the in-program documentation for details.
Added boundary data for the states of India. Indian states do not have flags per se, but state emblems will be displayed in lieu thereof.
Tracks without elevations attached to points are now visible in Map Panes.
Changing the font size with ctrl+/ctrl- or the program
