How does on get the date function to work in Libre Office spreadsheet?

Hi, I've formatted the cells as date mm/dd/yy and entered the values as is. Also tried by preceeding with equal sign in case deemed to be a formula but neither works. I assume a difference between two days yields the difference in days, correct? Or are the formula different than plain math? Eduard the Osborne guy at last meeting

We'll also cover some notable gaming Linux distros, such as Lakka, and ChimeraOS. RTFM: termdown - turn your terminal into a countdown timer (or stopwatch)! For this month's RTFM, Brad Vokey will give us a quick demonstration of some of the features of termdown, a python countdown timer for the terminal which he has used in the past to count down the MUUG virtual meeting breaks.

*nix in action at the Skullspace Hax Festival March 31-April 2nd
by Mark Jenkins 27 Mar '23

27 Mar '23

Hey Folks, I'm organizing a festival at Skullspace (374 Donald) next weekend, Friday March 31 through Sunday April 2nd. https://hax.skullspace.ca Includes: * A movie night on Friday night * General interest talks from 9:30am to 3pm Saturday * Information security talks, 3pm-6pm Saturday * An early Saturday night party (6pm-10pm) (tickets required) * A music open mic and jam 11am-3pm Sunday * Electronics market and auction 3:30pm-5pm Aside from the Saturday night party these are free events. Directly relevant to MUUG members, one of our Saturday talks will specifically feature a *nix systems in action: At 10am James Paskaruk will present on the Zynthian Open Synth Platform which is a many featured synthesizer platform that runs on a Rapsberry Pi. This talk will be delivered remotely and we will make the video conference link available on our website for folks unable to make it in person. ---- We're branding the 3pm-6pm cyber security talks as Skullspace Security CSides, kind of a light weight BSides. For this we've already got 3 talks, including my *nix adjacent talk about PGP smart cards. (I may make a MUUG presentation of that subject matter some day) I know it's now very short notice ask, but I could still use an infosec talk or two at 4:30pm or 5pm. Even a short talk, like 15 minutes including Q&A would be welcomed. For speakers we're offering a honourium and evening event ticket. Happy Hacking, Mark Jenkins

Re: [RndTbl] Roundtable Digest, Vol 218, Issue 12

I have had more time to look around a bit, and see that what I'am looking for is classed as a "No/Low Code App Development" platform. Companies of course wish customers to use and implement new apps as cloud based apps, but some will support self-hosted instances of their platforms. Some commercial and open source examples include but not limited to, are: Retool Openblocks Joget ToolJet appsmith A recurring theme is the platform distribution and self hosting via Docker instances rather than a traditional software installation or Build process onto the native OS. Further comments welcome on No/Low Code App development platforms and the use of Docker for DEV and PROD self-hosted installations.

Rapid prototyping of multi-user database for LAN/Server environment
by Brock Wolfe 26 Mar '23

26 Mar '23

I am looking for a software platform for prototyping a multi-user database, hosted in a LAN/Server network. The primary focus is on rapid prototyping of the databases, forms, screens, reports, etc. over scalable and production grade software platform suite (ie. LAMP) A little looking around, and I found the similar LibreOffice BASE and HyperSQL (www.hsqldb.org) Any suggestions, recommendations? Thank you in advance for the help. Regards Brock

EAC equivalent for Linux - found! (more or less)
by Adam Thompson 25 Mar '23

25 Mar '23

I, and I know a few of you, have long been looking for an equivalent tool under Linux to Windows’ Exact Audio Copy. I just stumbled upon a new (to me) possible contender: Whipper. Source at: GitHub - whipper-team/whipper: Python CD-DA ripper preferring accuracy over speed<https://github.com/whipper-team/whipper> Binaries appear to mostly be in your distro’s repos? Or so the github page reports, at least. It does use the new-ish libcdparanoia to do the ripping, under the hood – it seems that product has matured and more or less reached parity with EAC. I have not tried this yet, so I can’t vouch for its quality relative to EAC, but it’s apparently popular enough that MusicBrainz’ Picard has specific support for its logfiles. For proprietary-Darwin fans, the equivalent there now appears to be X Lossless Decoder: Lossless audio decoder for Mac OS X (undo.jp)<https://tmkk.undo.jp/xld/index_e.html>. YMMV. -Adam

Unix at 25
by Gilbert Detillieux 14 Mar '23

14 Mar '23

What? Don't you mean 52? (Or actually almost 54 by now?) So, back in 1994, Peter H. Salus wrote a book "A Quarter Century of Unix", and then an article with the title "Unix at 25" for the October 1994 issue of Byte Magazine. At the in-person MUUG meeting last week, one of the give-aways was a print edition of that issue of Byte. For those who are sad they missed out in this prized issue, here's an electronic copy of the Salus article... https://www.landley.net/history/mirror/unix/art3.htm And for those interested in a copy of his book (either purchasing a print copy, or downloading the PDF), you can find out more about it here... https://wiki.tuhs.org/doku.php?id=publications:quarter_century_of_unix ... along with other historical Unix publications here... https://wiki.tuhs.org/doku.php?id=publications:start Enjoy the trip down memory lane!

HDMI extenders
by Kevin McGregor 11 Mar '23

11 Mar '23

Here's another question I was going to ask at the meeting but forgot about. It's not UNIX/Linux-related but I was hoping for some input. Does anyone have experience with HDMI-over-Ethernet extenders? Do they work? Do the less-expensive ones work? :-) Should I just get a really long HDMI cable? What's the upper length limit for HDMI cables (1080p)? It would be under 50 ft.

intel-media-driver with Intel 1165G7 and Rocky 9
by Chris Audet 04 Mar '23

04 Mar '23

@Alberto just a quick follow up from last meeting, you had suggested installing the official Intel driver to get the most out of this CPU. I installed as per this kb <https://rpmfusion.org/Howto/Multimedia>, everything seems OK (it shows up installed because I ran it again as an example, forgot to copy the output first time): [root@what ~]# dnf install intel-media-driver Last metadata expiration check: 2:11:34 ago on Wed 15 Feb 2023 03:49:21 PM. Package intel-media-driver-21.1.3-1.el9.x86_64 is already installed. Dependencies resolved. Nothing to do. Complete! Only thing I was wondering was how to verify that the OS is actually using the newly installed driver. After reboot, the Gnome settings app is reporting "Mesa Intel® Xe Graphics (TGL GT2)", I'm not 100% sure but I think that's what it was displaying before the install as well. In any case I'll keep using it and will report back if anything exciting happens. Thanks for the tip 🙂
