05:58 <razzy> Good morning I wish to all! off topic: I have trouble making backup dump/restore on f2fs flash friendly filesystem. anyone has experience?

05:59 <Regenaxer> Good morning razzy!

07:09 <beneroth> Good morning razzy, Regenaxer

07:10 <beneroth> razzy, sorry I've never used f2fs

07:11 <Regenaxer> Hi beneroth!

07:35 <razzy> anyone tried to make "live" backup of whole root filesystem? i am trying to use fsfreeze

07:36 <Regenaxer> I usually back up only certain directories

07:36 <aw-> razzy: hi, not familiar with f2fs, but if it's on Linux you can just rsync / to a file, and exclude /dev and /proc and /sys etc

07:37 <aw-> rsync to tar archive

07:38 <razzy> aw-: than i cannot just dd copy to new disk

07:38 <aw-> sure you can

07:38 <aw-> tar -x | dd of=disk

07:39 <aw-> you can do all that on one line rsync / | tar | dd; # or something like that

07:39 <Regenaxer> Why rsync *and* tar? Just tar does the same, no?

07:40 <razzy> aw-: will it work? usecase: I exchange main bootable root disk. i dd copy backup to new disk and i think it will not work

07:41 <aw-> i dont know your entire situation so i can't confirm, so many variables here

07:43 <razzy> i will think about tar now

07:43 <razzy> thank you

08:15 <razzy> aw-: do tar break when there are changes to files it is readinf?

08:15 <razzy> reading?

08:42 <razzy> tar seems nice

08:55 <Regenaxer> It is the oldest of such tools. I used it already in the 1980s

09:44 <hunar> Hello Regenaxer, I have a weird problem.. I'm following this tutorial https://picolisp-blog.hashnode.dev/web-application-programming-in-picolisp-prefix-classes which says the prefix class +Style let's me use custom css styles, in the html function I loaded a css file called test.css, I typed an initial css file and ran the sever,

09:44 <hunar> everything was fine.. BUT

09:45 <Regenaxer> Hi Hunar!

09:45 <hunar> then I changed the contents of the css file and the browser still sees the old file, I even deleted the css file but the browser still sees the old content of css at http://localhost:8000/test.css .. I closed everything restarted the server and still the same problem

09:46 <Regenaxer> It is cached in the browser

09:46 <Regenaxer> You can do Shift-Reload

09:46 <hunar> :D

09:46 <hunar> that was it

09:46 <Regenaxer> :)

09:47 <hunar> Thank you very much .. is that the default behavior? It makes tweaking the css file harder

09:48 <Regenaxer> yeah, but you need to reload the page anyway

09:48 <Regenaxer> so just shift is added

09:48 <hunar> Great :) I can live with that

10:28 <razzy> Regenaxer: i have never used tar to filesystem backup till now

10:42 <beneroth> Hunar, this is standard browser behaviour

10:42 <beneroth> Hunar, one way around is to have some random value or date/time into the css filename, so the css filename changes.. but then of course the link to it in HTML must change too

10:43 <beneroth> razzy, tar = TApe ARchive

10:43 <beneroth> very old. many functions. very useful.

11:43 <hunar> Thanks beneroth :)

18:53 <beneroth> quote of the day: "abstraction is a tool for managing complexity, not a tool for reducing knowledge."

18:53 <beneroth> I guess that is kinda the primary confusion people have with OOP.

18:54 <Regenaxer> Yeah, true

18:55 <Regenaxer> not hiding stuff to "protectthe programmer

18:55 <beneroth> exactly

18:56 <beneroth> bbl, schönen Abend :)

18:56 <Regenaxer> cu :)
