Now in its 20th year of supporting and promoting the FOSS community, SCaLE 20x – the Southern California Linux Expo – will be held at the Pasadena Convention Center March 9-12, 2023.

This 4-day annual event brings together the vibrant Open Source user community, tech industry leaders, developers, users and many more.  Session track themes have included security, developer, embedded, medical and legal to name a few.  The expert speakers have never failed to impress and inform.  Your biggest challenge will likely be trying to pick which session to attend.  One certainty: Saturday’s keynote by Arun Gupta will be standing room only.

Since my first SCaLE, way back to 3x, the expo floor has been my favorite hangout.  The expansive exhibit hall provides an opportunity to meet the people behind a favorite distribution or application.  There are compelling demonstrations of Open Source-based solutions, educational offerings and companies looking for top talent.  Oh, and SCaLE exhibitors always have the best swag.

Would you like a glimpse of the future of Linux/FOSS? SCALE is a family friendly event that welcomes all ages.   SCaLE: The Next Generation, the track focused on kids and the work they do in OSS, is back for 20x.  All sessions are delivered by K-12 students and highlight interesting work or projects these students have been working on. It also includes hands-on activities for younger attendees.  Topics are expected to include security, video editing, big data and more.  These young folks will leave you feeling confident in the future of FOSS.

Other co-located events include Ceph Days SoCal, Kubernetes Community Day, DevOpsDayLA, PostgreSQL @ SCaLE , SCaLE Kids and Embedded Apprentice Linux Engineer (E-ALE).  Always popular, the Hands-On Beginner Linux Training is here for 20x.  Book your spot early for this one.

Hello, the subject says it all. The option "show thumbnails" is set to "Always" and it shows thumbnails from external usb-disks but not from phones connected via usb / mtp. The problem seems to be described here: https://gitlab.xfce.org/xfce/thunar/-/issues/298 and as described there the cpu load goes up and top shows gvfsd-mtp on the first position, but they did not fix it since 2 jears...

Does anyone have an idea or workaround?

Hello,
I know Linux to some extent and can do daily tasks and use it as a server. You can say that I am a Linux administrator, but many Linux administrators don't really understand how Linux and the operating system work. I want to learn Linux in depth. What book do you recommend?

Thank you.

Tomáš Matějíček has announced the availability of Slax 15.0.1 (based on Slackware's "Current" branch) and 11.6.0 (based on Debian 11.6.0). Both new releases of the project's minimalist live distribution bring updated software as well as improved persistence: "I am excited to announce the release of Slax's latest versions....

I want to capture sections in the following format, and store the values of `CATEGORY`, `TITLE` and the list of `KEYWORD` (perhaps a good idea is to use an array).

Code: ## CATEGORY [TITLE] KEYWORD,KEYWORD 
## Body (empty lines allowed)
## END OF CATERORY [TITLE] Here is an example file

Code: ## FAML [ASMB] keyword,keyword 

## First Section
## Body
## END OF FAML [ASMB]

Some Code

## More text

## FALUN [GONG] truthfulness,compassion,forbearance

## Second section
## Some text
## END OF FALUN [GONG]

More Text I started with the following code that uses groups to then capture with `BASH_REMATCH`. One problem is that this handles only two keywords, whereas I want to handle any arbitrary number of keywords.

Code: while read line; do
  if [[ $line =~ ^##\ ([A-Z]+)\ \[([A-Z]+)\]\ (.*),(.*)$ ]]; then
    title=${BASH_REMATCH[1]}
    subtitle=${BASH_REMATCH[2]}
    keywords=${BASH_REMATCH[3]}
    keywords2=${BASH_REMATCH[4]}
    echo "Title: $title"
    echo "Subtitle: $subtitle"
    echo "Keywords: $keywords, $keywords2"
  fi

Hey all.

I am running Linux Mint 21.1 Cinnamon and are looking for the best GUI Open Source alternative for Teamviewer.
I will like if it will be as simple (or simpler )to use as Teamviewer.

Priorities:

1: Can remote control other Linux PCs
2: File transfer (not mandatory - but nice to have)

You suggestions/Experiences?

Regards

Noting that .... the debian website says...

"After partitioning your disk, you will need to obtain an installation CD or download the installer system. Once you finally sit down to do the installation (preferably with installation manual in hand), you will probably burn up 2 or 3 hours making it happen. An experienced installer can get a basic install done in under half an hour."

and also...

"The PowerPC platform runs really well with Linux. It's highly respected in much of the Linux world. Enjoy, and remember to give something back!"

I would like to opt for the half an hour option please.

from experience (and I AM AN AMATEUR!) my inclination would be the following steps...

1. download powerpc mac G4 ISO
2. use rufus to burn a USB stick to boot from
3. partion the drive (or just use a new drive)
4. boot into BIOS system on G4 and direct to boot from usb
5. follow the prompts to install debian

I have indeed gotten ARCHLINUX up and running on my old HP linux which seriously took me about 5 days of on and off again effort...!

My linux experience has been as follows:
Ubuntu -->
Debian -->
ArchLINUX -->
Fedora (only dabbling)

My main concern is that I have an inkling DVD ISO install might be better than USB ????

I am not sure what USB speed the G4 runs at nor how that compares to DVD ROM?

Any advice of previous experience is appreciated!

I would like to use the G4 in combination with a camera to monitor a room as a side project...
