@Wildcard Usually anything involving Kali is painful to read. Usually. As for people saying in questions I am prepping/I am learning/I am new, whether true or not, IMO, it just brings way down the quality of the question.
@derobert The Amazons is also a very hot place....
@Fabby In the wine site there used to be a list of known software with a bronze/silver/god tag in what touches to compatibility.

@Wildcard The follow up question to that should be "In the context of security, what would you use Kali Linux for that you couldn't use e.g. Ubuntu for?". Also "What tools would you not be able to use outside of Kali Linux?".

Hi @RuiFRibeiro
 
Thomas Ward
Thomas Ward
hands a link to the Sandbox where you can test chat message functions without impeding actual rooms' activities

@Kiwy I don't have experience with Mesos, but it might help if you explain the problem or open a question on it
you will probably reach more people with an actual question posted than asking here.
 
Kiwy
Kiwy
@ThomasWard Amazing link :D
Well My question is not one, it's several I need to find some clear documentation (clear being not the official one) about how to configure a framework with the use of share volume
 
Stephen Kitt

@Kiwy there’s a sandbox for Q&A formatting too:

Q: Experimentation Sandbox

CommunityThis is a sandbox post for experimenting with SE features, similar to the Formatting Sandbox on Meta Stack Exchange.

discussion support markdown formatting sandbox

there documentation but it's obscure like hell
@StephenKitt some guys have played with unicode encoding and css injection :D

still likely to reach more users via asking individual questions than asking in chat
just saying ;)

Yes I know, but I don't have a unique question and asking one question at a time won't help me. I wish I had a training on Mesos before having to mess with it :d
:D

I used to teach adults about open source and Java at l'INSA

INSA ? Adults ? I think you are mistaken...
INSA = dumbass student
like any student
 
Stephen Kitt
Stephen Kitt
they have a bunch of « master » that are mostly attended by adults as part of professional training rather than post-bac studies
and for the open source stuff I was teaching the professors
 
Kiwy
Kiwy
nice
I Wish i could teach a bit I like being the one training the other, but I'm no expert in any domain just a know a bit of everything
so not easy to teach a bit of everything :D
 
Stephen Kitt
Stephen Kitt
@Kiwy that’s IMO the best place to start from
because if you know too much then you’re too disconnected from the concerns of people trying to learn
and having to teach someone is the best way to become a real expert at something (as in, really understand it)

I don't remember who was asking about putting $HOME in git, but I just stumbled across this:

Q: Are there pitfalls to putting $HOME in git instead of symlinking dotfiles?

CalebI have for many years had my entire $HOME directory checked into subversion. This has included all my dotfiles and application profiles, many scripts, tools and hacks, my preferred basic home directory structure, not a few oddball projects and a warehouse worth of random data. This was a good thi...

@StephenKitt about a year and half ago you recommended me of a backup utility you like. I don't recall the name, something with G, like GeedyBackups or something like that? I remember I took a look at the manual and it had more than about 500 or 700 manual pages.
 
user141350
Why would a backup utility have so many man pages? I mean, I try to understand why would so many explanations are needed for just doing backups? You have helped me in the pass with backing up my environment and based on your examples I conclude that very firm backup operations can be done with small scripts of up to 10 lines, so why hundreds if not more than a thousand of man pages for a backup utility?

If anyone feels like offsetting a revenge downvote with some (considered) positivity, and the question is still at -1 when you see it, I'll fish for upvotes once in my life at unix.stackexchange.com/q/476060/117549 in order to (3 years from now) achieve the "curious" badge for 5 well-received questions.
 
terdon

@JeffSchaller Revenge?
Odd to target the question and not the answer.
Both seem fine though, so +1 from me.
There are some people who object to self-answered questions. Maybe that's where the downvote came from.
 
Jeff Schaller
Jeff Schaller
@terdon my own guess, of course, but it was during a comment-discussion on another post, and I suspect that they were low-enough rep to not want to lose rep on an Answer downvote
 
terdon
terdon
Personally, I will almost always upvote self-answered posts, unless they're really bad, since I appreciate it when people make the effort to post and answer.

@JohnDoea because while your particular use case might be simple, not everyone's is.

@terdon I have a SEDE query to look for self-answered posts; some are "typos that went away" but some are indeed worth upvotes
 
derobert
derobert
@JohnDoea (I presume you mean pages of documentation, not actually 500 different man files, which indeed is odd)
 
terdon
terdon
yep. But hell, even in the case of typos that went away, I appreciate the effort of coming back and posting an answer.
 
derobert
derobert
Unless someone e.g., converted source code documentation into manpages. Which, actually, would still be odd.
@JohnDoea e.g., your ten line script wouldn't handle backups here, which involve backups from a few dozen machines, running several different operating systems & versions, to several different backup media.
And then different backup retention periods, frequency of full/differential/incremental backups, etc.
 
terdon
terdon
I used to have one that would backup different things to different places at different frequencies depending on what network my laptop was connected to, for example. And that was still a very simple, single-source-machine setup.
 
derobert

5:48 PM
But honestly, if a 10-line script works for you, then great! Do not add complexity you don't need. But do make sure it does things you DO need. Like, have you confirmed your backups work (ideally by testing a restore)? Does it make sure the backups ran last night, and let you know if something went wrong? Does it handle expiring old backups (manual expiration being an easy source of accidental admin error)? How sure are you that you've backed up all your important files? Etc.
Not everyone needs to run Bacula/Bareos/Amanda. In fact, most people don't!
 
user141350
6:03 PM
@derobert I checked everything I know relevant for the 2 scripts I work with (one for immediate backups and another one for cron-scheduled backups though I no longer use the second one as Linode/DigitalOcean offer weekly backups that are enough for me as scheduled backups). I think it has become a standard in all hosting companies (even maximally-self-managed like these two).
 
derobert
derobert
@JohnDoea I bet their backups consist of a lot more than 10 lines of shell :-P
But yeah, if ten lines of shell works for you, there's nothing wrong with that. Simplicity is nice!
I don't actually have anything running on Linode or DigitalOcean, so not sure what backups they offer, but the same caveats apply to backups offered by third parties as well. Have you confirmed a restore works? That's essential — you don't have a backup until you've confirmed restore is possible.
 
user141350
6:22 PM
@derobert when I checked the backup and resotre functionality in DigitalOcean it worked fine (I think of opening an account of Linode but their basic services should be very similar to these of DigitalOcean).

Anyone else get a new Kindle today?
(Which did mean having to come up with a name for one... finally went with Field, after Cyrus West Field — yes, that's an actual person's name...)

@JohnDoea Take a look at Borg Backup. There is also a sister project with @Kusalananda uses, whose name escapes me for the moment - begins with r. They're both command line utilities.
Ah, restic is the name, I think. They are both deduplicating backups. Pretty much state of the art.
Hi folks.
@derobert A name for your Kindle? (And hi.)
 
derobert
derobert
@FaheemMitha Yep. That's the 4th one, others are Kelvin, Varley, and Gooch.
 
Faheem Mitha
Faheem Mitha
@derobert I don't follow. Are you required to name them?
 
derobert
derobert
@FaheemMitha Well, Amazon will happily call them "Anthony’s Nth Kindle", but...
 
Faheem Mitha
Faheem Mitha
@derobert Oh, I see. They have a presence in the "cloud".
Well, the Amazon cloud.
 
derobert

And it shows on the screen in the top-left corner.

Ok.
 
derobert

And of course it connects to the WiFi network, so it gets an IP address and thus has a hostname
 
Faheem Mitha
Faheem Mitha
@derobert Just wondering what is behind your naming scheme...
@derobert So people can break into it?
 
derobert
derobert
@FaheemMitha People involved in the first transatlantic telegraph cables, that's the naming scheme I use for Kindles.
Computers, smartphones, and tablets all get named after scientists
 
Faheem Mitha
Faheem Mitha
@derobert Interesting. Gooch? Really?

Daniel Gooch
Sir Daniel Gooch, 1st Baronet (24 August 1816 – 15 October 1889) was an English railway locomotive and transatlantic cable engineer and Conservative politician who sat in the House of Commons from 1865 to 1885. He was the first Superintendent of Locomotive Engines on the Great Western Railway from 1837 to 1864 and its chairman from 1865 to 1889. == Early life == Gooch was born in Bedlington, Northumberland, the son of John Gooch, an ironfounder, and his wife Anna Longridge. In 1831 his family moved to Tredegar Ironworks, Monmouthshire, South Wales, where his father had accepted a managerial post...

I know there was a scientist called Lord Kelvin. I thin the temperature unit is named after him.
@derobert Oh.

Scary thing is that I now have 107 hosts in my in-addr.arpa zone. For home. Wow...
Anyway, lunch time.
 
Faheem Mitha

thin -> think.

Yeah, the unit of temperature is named after him. Kelvin did a lot of stuff, including work on the transatlatic cables.

@JohnDoea there are a few tools I like for backups. I remember mentioning automysqlbackup to you; that backs MySQL databases up. For complex backups in enterprise-style environments, to tape robots, I use Bacula (now also forked as Bareos; don’t ask me which is better, I don’t know). For my own backups (local and remote) I now use BorgBackup.
 
Faheem Mitha
Faheem Mitha
@derobert Impressive.

@RuiFRibeiro thank you, sir! I appreciate the fake internet points :)
Wow, seeing stuff like du /etc/ -hsx * still hurts my brain, even after using Linux for as long as I have
 
user141350
7:32 PM
Indeed @StephenKitt it was BorgBackup I think you mentioned as well. The manual there was very very lengthy, I think the lengthiest I ever seen.
 
Stephen Kitt
Stephen Kitt
@JohnDoea heh take a look at Bacula’s manual, it’s much longer
 
Rui F Ribeiro

@JeffSchaller Share your pain, also had revenge voting in a couple of questions....
 
Faheem Mitha
Faheem Mitha
7:47 PM
@JohnDoea Not really. It's for all the commands, and it includes examples, which is good. And there is separate help for each command. E.g. borg help list.
/me mumbles about young whippersnappers who don't appreciate good documentation.
@JohnDoea And if you use Borg, make sure to use an up to date version. It's still changing quite fast.
 
Stephen Kitt
Stephen Kitt
@FaheemMitha and most importantly, if you use it for remote backups, ensure that the versions of Borg on the server and on the clients are compatible
 
Faheem Mitha
Faheem Mitha
@StephenKitt Yes, that too. Good point.
@derobert Surprisingly, a search for Daniel Gooch comes with The Times obituary from 1889 - ghgraham.org/text/danielgooch1816_obit.html

I remember Kusalananda or someone else mentioned what borgbackup can do that rsync can't. But I forget.
https://chat.stackexchange.com/transcript/message/44685849#44685849
kiwy said: "@tim I sync Rsync doesn't do deduplication "
I also asked somewhere on the main site if rsync needs to be installed on target machine, but I forgot where. I guess it does but it is always installed by default?
 
Faheem Mitha
Faheem Mitha
@Tim borgbackup is much better than rsync as a backup system. rsync is just a copying program.
@Tim No, rsync isn't always installed by default.
