How does on get the date function to work in Libre Office spreadsheet?
by eh＠eduardhiebert.com 08 May '23

08 May '23

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

creat() fails on non-root owned file when stickybit set on dir (tcsh) (new kernel bug?)
by Trevor Cordes 03 Jan '20

03 Jan '20

Just upgraded to F30 with kernel 5.3.12 (not going to F31 quite yet). Hit a weird error that didn't happen in the previous kernel/OS: If my dir has stickybit set, in this case /tmp, then root can't use tcsh's ">!" redirection on a file owned by another user (permission denied). F29 ">!" allowed it just fine (kernel 5.3.11). I checked and tcsh versions didn't change, except just the bump to F30. ">!" in tcsh is the same as > in bash. tcsh lets you set an option to >! require explicit instruction to clobber existing files so you don't accidentally > an existing file without realizing it. That's the extra ! after the >. It's funny, because root can still append to the file (>>), rm it, chmod, etc., just not this explicit clobber. Funnier still is it works in bash (using >) but the OS is still giving it the permission denied. (See below.) It looks like tcsh is using creat() and that is the syscall returning the error. as root: tcsh sudo -u trevor touch /tmp/t echo foo >> /tmp/t # ok echo foo >! /tmp/t # Permission denied. strace on 5.3.12 F30 (error): dup(19) = 0 fcntl(0, F_SETFD, 0) = 0 dup2(17, 1) = 1 dup2(18, 2) = 2 creat("t", 0666) = -1 EACCES (Permission denied) write(18, "t: Permission denied.\n", 22l: Permission denied. ) = 22 strace on 5.3.11 F29 (ok): dup(19) = 0 fcntl(0, F_SETFD, 0) = 0 dup2(17, 1) = 1 dup2(18, 2) = 2 creat("t", 0666) = 3 fcntl(3, F_GETFL) = 0x8001 (flags O_WRONLY|O_LARGEFILE) fcntl(3, F_SETFL, O_WRONLY|O_LARGEFILE) = 0 ... strace with bash on 5.3.12 F30 (no error! note the double try!) (command for bash is just: echo foo > /tmp/t) openat(AT_FDCWD, "/tmp/t", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 EACCES (Permission denied) openat(AT_FDCWD, "/tmp/t", O_WRONLY|O_TRUNC) = 3 fcntl(1, F_GETFD) = 0 fcntl(1, F_DUPFD, 10) = 10 ... So bash uses openat instead of creat, but still gets EACCESS, but then retries with slightly different options... almost like bash hit this same bug but has already worked around it. So is this a kernel bug / change in API? Should I report this to kernel bugs or to tcsh bugs? This is a "bug" in the sense that something changed because I've been doing this type of command for, oh, 20 years, and it's always worked before. And I know Linus doesn't like to change the existing user interface into the kernel.

Linux for the disabled
by Frank H 05 Dec '19

05 Dec '19

I was diagnosed with ALS earlier in the year. Among other things, my voice is quickly becoming unintelligible, and my hands are weakening to the point that one day I won't be able to type. Eye tracking hardware/software is probably going to my mode of communication. Are you guys aware of anything like that for linux? When I use Windows, I feel like I'm in a stranger's house. Thanks,Frank

The "Save .org" petition
by Glen Ditchfield 27 Nov '19

27 Nov '19

As you may have heard, ICANN removed the price caps on .org domains, then quietly decided to sell the .org registry to a private equity firm linked to a former ICANN CEO and several American billionaires (https:// www.theregister.co.uk/2019/11/26/org_selloff_internet/). So, a bunch of respectable organizations have started a petition to stop that, at https://savedotorg.org/ . Signing might help.

Our VA4WAN group (Winnipeg-wide amateur radio wi-fi / IP network) is doing some big stock cleanups and we have excess gear that is being given away at VE4WSC for anyone who wants it.

Printers needing a new home
by Adam Thompson 25 Nov '19

25 Nov '19

(Hint: hit Reply, not Reply-All. Don't be that person.) I have two printers that don't meet my needs right now just taking up floor space. I need them to stop taking up so much space. I figure *someone* on these lists will be interested in free mid-range laser printers, right? First: 1 x HP LJ2000dtn (PCL6/PS3, 2 trays, duplexer, network, 24ppm) - tray "2" can't be inserted right now, which makes the printer mostly useless until that gets fixed. Free to a good home that cares enough to repair it - *probably* an easy job, no guarantees. No guarantees on the rollers, either, but it worked OK last time I used it. You pick it up from home (near St. Vital Center) or office (near UofM). It's kinda bulky but not that heavy (42lbs, but it comes apart) -> https://www.laserpros.com/img/TechTips/hp-2300-printer-specs.pdf And, recently acquired used to replace the HP but I screwed up on the model# (I thought it was a T652dn): 1 x Lexmark T652n (PCL/PS, 1 tray + 1 extra tray, network, 52ppm) comes with 2 extra toner cartridges (~10k pages each). Free to anyone who doesn't need duplexing. (Oops on my part when I got it.) Makes an alarming but apparently harmless thumping sound, and the 3rd-party non-Lexmark toner tends to oversaturate (you can adjust density in print driver to fix this). Everything seems to work, regardless. Weighs >50 lbs and is a rather large & awkward cube even after disconnecting the trays, so you can come pick it up. (It'll fit into the back of any taxi without issues.) -> http://brochure.copiercatalog.com/lexmark/0030G0125.pdf Reply if interested. They'll get dropped off at Urban Mine or similar if no-one wants them. -Adam
