07:00 schestowitz-TR; I'm mostly set now, main remaining task is data migration and stuff like
07:00 schestowitz-TR; thunderbird
07:00 schestowitz-TR; jriddell et al did a glorious job on kde neon
07:00 schestowitz-TR; so if you like KDE, you might want to try it one day

08:15 Techrights-sec; I'll have to take another look at KDE sometime soon. I'm risking getting too
08:15 Techrights-sec; locked into XFCE4 with all the customizations currently.
08:16 schestowitz-TR; xfce4 is nice also, I still use it on an old laptop, but if you don't have capacity constraints no compelling reasons to use it.... it still lacks some powerful features and its native stuff (mousepad, file manager etv) leaves much to be desired
08:19 Techrights-sec; I tend to mix and match the extras, like file manager and text editor
08:19 Techrights-sec; XFCE4 is just the DE
08:19 schestowitz-TR; did you receive rianne's email?
08:20 schestowitz-TR; it's a 10+ y-o galaxy without number, no network access, no wifi
08:20 schestowitz-TR; we use that as a camera now
08:21 schestowitz-TR; on LAN
08:21 Techrights-sec; Nope. Which account / time? There's nothing in the spam boxes either.
08:34 Techrights-sec; Maybe it's trapped in greylisting? What was the topic?
08:35 schestowitz-TR; maybe wrong email address, it was just a photo
09:15 Techrights-sec; ack

09:15 -TechrightsBN/#boycottnovell-DistroWatch.com: KDE neon
09:15 Techrights-sec; re-packaged Ubuntu
09:16 schestowitz-TR; yes, but they are no friends of Canonical and some of it devs followed me in Twitter and RTd while I was still there
09:21 Techrights-sec; ack
09:22 schestowitz-TR; of course DST is already causing minor niggles in some clients' systems. What is DST good for? NOTHING. In TM and TR I never saw any issues related to ths. IRC logging also works fine, it may simply mean leap or same hour twice.
09:34 schestowitz-TR; the only upside is, that give rianne and I something to put in handovers
10:50 schestowitz-TR; ecording paten video, very long, in a few mins

14:22 schestowitz-TR; if you are aware of a software frameworby which to distribute video encoding, tell me/point me
14:22 schestowitz-TR; as we might need to implement somethng of our own
14:22 schestowitz-TR; one option is ffmpeg file split, e.g. into 30-min shunks
14:22 schestowitz-TR; then sending these to different machines
14:22 schestowitz-TR; process
14:22 schestowitz-TR; then re-assembled ad merge
14:22 schestowitz-TR; the very cpu-intensive part is the watermark
14:22 schestowitz-TR; not the format shift
14:22 schestowitz-TR; I've been reluctant to add anything more as it would slow things down even further
14:22 schestowitz-TR; and it's grinding away at the file system
15:03 Techrights-sec; not aware of any such video tools but there might be some or it might be
15:03 Techrights-sec; possible to script
15:03 Techrights-sec; however, 30 minutes is maybe too long anyway
15:51 schestowitz-TR; did you type anything before the buffer was reset?
15:51 schestowitz-TR; I rsync over vonick to bubi right now
15:51 schestowitz-TR; bubi is an elephant's name
15:51 schestowitz-TR; thenm I will rsync againthen do some sanity check
15:52 schestowitz-TR; also installing some software like thunderbird at the moment
15:53 Techrights-sec; no, just typed in the wrong window
15:54 schestowitz-TR; Speaking of Thunderbird, have you seen mention anywhere about how to get
15:54 schestowitz-TR; past the block that GMail will put into place at the end of May? There
15:54 schestowitz-TR; were some hints about allowing an "application password" but no functioning
15:54 schestowitz-TR; guides or tutorials anywhere.
15:58 Techrights-sec; Speaking of Thunderbird, have you seen mention anywhere about how to get

15:58 Techrights-sec; were some hints about allowing an "application password" but no functioning
15:58 Techrights-sec; guides or tutorials anywhere.
15:58 Techrights-sec; Sylpheed, Thunderbird, Re-Alpine, Mutt, and all the others will soon be excluded
15:58 Techrights-sec; from working over GMail. For some that is a big problem. Even for those that don't use GMail it is a problem because Google is
15:58 Techrights-sec; that much closer to gaining
15:58 Techrights-sec; control over the protocols involved. They already break IMAPS. By eliminating
15:58 Techrights-sec; the non-Google clients and saddling people with their webmail, not only
15:58 Techrights-sec; will tracking capabilities go through the roof, but also their potential to
15:58 Techrights-sec; close off the e-mail 'market'
15:58 Techrights-sec; and turn written messaging into something proprietary which they control totally
16:00 schestowitz-TR; I know close to nothing about it, I did a view about it this year
16:00 schestowitz-TR; but I used yahoo more than 20 years ago
16:00 schestowitz-TR; then an uncle's domain
16:00 schestowitz-TR; then my own in 2004
16:00 schestowitz-TR; I also has cs.man.ac.uk address
16:00 schestowitz-TR; but those are a bad idea to use
16:00 schestowitz-TR; along with sp accounta dna other cademic accounts
16:00 schestowitz-TR; *isp
16:00 schestowitz-TR; *i did a video
16:03 Techrights-sec; :(
16:03 Techrights-sec; like riseup
16:06 schestowitz-TR; gmx can shut down any day
16:06 schestowitz-TR; for legal reasons
16:06 schestowitz-TR; financial reasons
16:06 schestowitz-TR; they and gulag cAN also suspend and blacklisty peole
16:06 schestowitz-TR; turning the email system into the social control media with "@" for email rather
16:06 schestowitz-TR; than handle names like in twitler
16:06 schestowitz-TR; "sorry, yur email account is not compatible with our value; you insist on two genders only"
16:06 schestowitz-TR; "no free email for yuou"
16:25 schestowitz-TR; i have a rather dumb question
16:25 schestowitz-TR; but your ballpark
16:25 schestowitz-TR; does rsync involve any crc checks
16:25 schestowitz-TR; by which it can detect and announce data issue sna mitsmatches?
16:25 schestowitz-TR; network has that, but we still use checksums
16:25 schestowitz-TR; I want to know if there was a corruption in daata from vonick
16:27 Techrights-sec; ok
16:27 Techrights-sec; SNA?
16:27 Techrights-sec; rsync has a rolling checksum as it passes through blocks of each file
16:27 Techrights-sec; with rsync the transfer will be sound but the question would instead be
16:27 Techrights-sec; whether or how uch the data was already corrupted on the defective drive befor
16:27 Techrights-sec; the transfer
16:29 schestowitz-TR; let's just say that this issue went on for like a month
16:30 schestowitz-TR; and it always declares recovery based on what I saw
16:30 schestowitz-TR; and moreover I did not see any weak binaryy crashes
16:30 schestowitz-TR; or data refusing to load
16:30 schestowitz-TR; so I can hope the system always found OK blocks to work with
16:30 schestowitz-TR; when I left ted I did at one point see a message like,
16:30 schestowitz-TR; "this is not supposed to happen! Taata will be lost"
16:30 schestowitz-TR; That was already around the time I was offloading data off the machine, which was 11
16:30 Techrights-sec; openzfs has checksumming of individual files and, to a certian extent, error
16:30 Techrights-sec; correction but EXT4 lacks that
16:31 schestowitz-TR; re files, i think I did OK overall. what I lost from teen years was of little value
16:31 schestowitz-TR; like very lousy email correspondences, mostly family
16:31 schestowitz-TR; and maybe some graphics stuff of a teen
16:31 schestowitz-TR; inc. winamp theme
16:31 schestowitz-TR; and music
16:32 schestowitz-TR; music that I can recover, it's not mine
16:32 schestowitz-TR; my mail goes back 20+ years
16:45 schestowitz-TR; halfway not in rsync
16:45 schestowitz-TR; I will do a second pass
16:45 schestowitz-TR; how can I "ork" thunderbird on one machine to ensure I do not launch it onthe old one by accident?
16:45 schestowitz-TR; I did have this issue before
16:45 schestowitz-TR; pop3 and all means I risk breaking account consistency
16:45 schestowitz-TR; one option is to remove thunderbird completely from the old machine
16:45 schestowitz-TR; another is to disable account checks
16:45 schestowitz-TR; or "offline mode"
16:45 Techrights-sec; I'm not sure of how to have an exclusive lock across separate systems
16:45 Techrights-sec; maybe use one account read-only. POP3 should not be used, only IMAPS. It
16:45 Techrights-sec; can either leave the mail on the server or download it or both
16:55 schestowitz-TR; back to keyboard
16:55 schestowitz-TR; thought:
16:55 schestowitz-TR; i have directory "blah" in ~
16:55 schestowitz-TR; I want all files in blah to be accessible
16:55 schestowitz-TR; but NONE to be changed
16:55 schestowitz-TR; what permissions/user/other?
16:55 schestowitz-TR; chomd 555 for ~/blah covers all case?
16:55 Techrights-sec; I'd say disable it partially or completely on the old machine
16:55 Techrights-sec; 551 or 555 for the directories 444 or 440 for the files
16:56 schestowitz-TR; can I now just do that at the top level rather than recursievely?
16:59 Techrights-sec; It has to be recursive
16:59 Techrights-sec; find . -type d -exec chmod o=rx,g=rx,o=x {} \; -print
16:59 Techrights-sec; find . -type f -exec chmod o=r,g=r,x= {} \; -print
16:59 Techrights-sec; or something like that
17:11 schestowitz-TR; how about the approch os selective write -protection
17:11 schestowitz-TR; or
17:11 schestowitz-TR; change directory names
17:11 schestowitz-TR; so that any attempts to even access these files will result in errors?
17:11 Techrights-sec; the partition could be mounted read-only but only if /var and the others are
17:11 Techrights-sec; elsewhere
17:11 Techrights-sec; You could also make a new thunderbird profile and move/rename/delete the old one
17:12 schestowitz-TR; in the past I did mv ~./thunderbird somethinglese
17:12 schestowitz-TR; I think that should be enough
17:12 Techrights-sec; yes
17:12 schestowitz-TR; to detect any writes to othgeher files
17:12 schestowitz-TR; I can run some CLI stuff with aname or date
17:16 *psydroid2 (~psydroid@memzbmehf99re.irc) has joined #boycottnovell
17:17 schestowitz-TR; til programs on my system with lock files that cannot be copied acrorss:
17:17 schestowitz-TR; firefox

17:17 schestowitz-TR; gerbil (gemini)
17:17 schestowitz-TR; gnome authenticator

17:18 schestowitz-TR; librewlf
17:18 Techrights-sec; ack
17:18 schestowitz-TR; netsurf
17:18 schestowitz-TR; ii
17:20 schestowitz-TR; ok, first rsync pass donme
17:20 schestowitz-TR; my apprich was to separate files I rarely use from the ones I actiovely need
17:20 schestowitz-TR; so ended up with 89 GB
17:20 schestowitz-TR; that keeps backups of /home at under 100GB
17:21 Techrights-sec; ack
17:21 Techrights-sec; remember, rsync can copy errors, too
17:21 Techrights-sec; the shell script from the other day uses hardlinks via rsync to avoid redundant
17:21 Techrights-sec; files taking up extra space
17:21 Techrights-sec; So if a file is unchanged between backups, rsync just makes a hardlink instead
17:22 Techrights-sec; of an extra copy.
17:22 schestowitz-TR; is there an rsync opt to highlight which files got changed when I do the second pass?
17:22 schestowitz-TR; the sizes do match
17:22 schestowitz-TR; du -sh
17:22 Techrights-sec; So if a file is unchanged between backups, rsync just makes a hardlink instead
17:22 Techrights-sec; of an extra copy.
17:22 Techrights-sec; yes, --dry-run
17:22 Techrights-sec; aka -n
17:24 schestowitz-TR; dry run took like 20 secs for the whole thing
17:24 schestowitz-TR; does it compute checksums so fast?
17:24 schestowitz-TR; also, it did not show which files changed
17:26 schestowitz-TR; I was just reading the manpage
17:26 Techrights-sec; rsync -a -v --dry-run /source/ /dest/

18:19 schestowitz-TR; it seems like the second pass is slower than the second
18:19 schestowitz-TR; without knowing all the nitty-gretty details
18:19 schestowitz-TR; I would guess that rather than flinging over the file en masse
18:19 schestowitz-TR; it now goes through the bul one by one and compres for any ddiffs
18:19 schestowitz-TR; which is probably what I want anyway
18:19 Techrights-sec; it just transfers diffs, errors and all
18:19 schestowitz-TR; I now use atime and mtime
18:19 schestowitz-TR; one helps me see what gets CHANGED
18:19 schestowitz-TR; the other what needs to be there and accessed

18:29 schestowitz-TR; iirc there is a cpu vs bandwidth tradeoff
18:29 schestowitz-TR; sometimes it can be cheaper to copy across the file
18:29 schestowitz-TR; than to compute the diffs between 2 files
18:29 schestowitz-TR; but to copy first, thenj compare just in case is not a bad idea
18:29 Techrights-sec; also filesystem bottleneck
18:45 *activelow has quit (Quit: leaving)
18:54 Techrights-sec; rsync won't detect errors, only copy the changes. The changes can be errors
18:54 Techrights-sec; themselves.
18:57 schestowitz-TR; yes, I am perfectly aware
18:57 schestowitz-TR; I just think I would sleep better at night knowing the transmission itself was OK
18:57 schestowitz-TR; and if some time down the line I have issue I can at least reassure myself
18:57 schestowitz-TR; it wasn't some sloppy rsync handling 20+ years of my work
18:57 schestowitz-TR; when I archiuve files (like phd stuff, I don't need to access this anymore)
18:57 schestowitz-TR; I put that on 3 external disks now
18:57 schestowitz-TR; it's like a shelf or warehouse
18:57 schestowitz-TR; one that does not need backing up over and over again
18:58 schestowitz-TR; I have some memos typed with my PC history and specs (not maintained for over a decade but still handy)
18:59 schestowitz-TR; in 2007 I moved from baine (university) to novatech, which I'd use until 2014 when I moved to ted
19:00 schestowitz-TR; ted lasted until 2020 when I moved to vonick
19:00 schestowitz-TR; vonick is still OK for the most part, but the disk is not in a good shape
19:01 schestowitz-TR; the specs are good though, it's good for encoding and some other stuff, so I want to use it for a long time to come, even if I boot from external media
19:02 schestowitz-TR; but cutting to the chase, when moving to ted in 2014 I was perhaps a little sloppy and was apprehensive because one external drive was failing and when rsyncing the files over to ted I only had partial scrollback, which I still have someone
19:02 schestowitz-TR; so I lacked confidence that all went smoothly
19:03 schestowitz-TR; I still have some backups of my university computers, but that is quite ancient and not terrible useful anymore, the important files was passed to the next pc and the config files are invalid to newer, modern versions of the same softare
19:03 schestowitz-TR; screenshots are better ways to get nostalgic about these

20:42 schestowitz-TR; that even caused plasma to mcrash a few times, due to lack of resources
