@FaheemMitha read error was related to sata. Plugging SATA again worked.

@PrabhjotSingh ok

How to find that computer is having viruses if any. @FaheemMitha

@PrabhjotSingh Related: unix.stackexchange.com/questions/4222/…

"A very important element of a virus scanner is having it updated with new signatures, so pick the package that has the best signature updates, and that works best for how you want to use it."

New signatures?

@PrabhjotSingh Is that a Linux machine, or not?

If not, no idea. If yes, why are you concerned? Does there seem to be stuff going on that shouldn't be?

Actually, Windows has an entire anti-virus software industry. Capitalism in operation. It's a beautiful sight.

I haven't seen viruses on my machine so far. FaheemMitha was saying there days back that may be someone using his internet.

So I asked. Never installed antivirus

@FaheemMitha I asked very silly question.

@PrabhjotSingh I did? When?

Viruses on the free Unix-like systems isn't an issue most of the time, though they do exist. It's even less so on the surviving non-free ones. Assuming there is anyone still using them.

@FaheemMitha I think they're referring to your unexpectedly large bandwidth usage.

@FaheemMitha When it comes to viruses on Unix systems, the main concern are systems that stores and forwards documents to Windows machines. Scanning such documents may be of value to the Windows systems being served.

Yes, bandwidth issue.

Sometimes I use flashdrive though rarely. It might have have viruses

@PrabhjotSingh My network usage was because of my backup scripts. No mystery.

@Kusalananda TH sort of, probably, gave me the answer to:

But it doesn't seem hard, anyway.

@FaheemMitha Well, I suppose you could just execute the extraction through an ssh invocation against the server. Since borg is guaranteed to be installed somewhere, you would be able to do that.

The only question is how to do the authentication securely.

... so that your borg credentials don't show up in the server's log files.

@Kusalananda What authentication?

It's not encrypted. And I'm using keychain for the ssh part.

BTW, do you encrypt your stuff?

@FaheemMitha Yes, especially off-site backups.

@Kusalananda Ok. It's probably a good idea, but I've historically never done that.

I tend to avoid saving sensitive information in accessible places.

And I hope the ramnode admins are criminals. But even if they were, I'm not sure what they would find of interest in my stuff.

Ugh, very hot over here.

@FaheemMitha what us keychain?

@Kusalananda 43°C here

43°C that's a lot it's around 25 here and it's perfect

May I ask why you guys don't mention rsync for backup? I think it is installed by default on *nix

@tim I sync Rsync doesn't do deduplication

@PrabhjotSingh A program to cache ssh authentication information.

@Tim rsync is very primitive. Though I actually still have it running for historical reasons. My backups till quite recently was just rsyncing to another machine. Which, needless to say, it's a real backup.

I still don't understand why @Tim's U&L account isn't linked to his Math one.

Are these two separate accounts, perhaps? If so, they should be linked.

And rsyncisn't part of any default installation I've heard of.

@FaheemMitha right now I'm learning c. For more efficient use of Linux which language should I pursue

@PrabhjotSingh There isn't any particular one.

If you are happy learning C, by all means, learn C.

But sometimes I find hard to install programs

Oh, and to be clear, when I said earlier "rsync is very primitive", I meant considered as a backup program.

@PrabhjotSingh I don't follow the connection.

Some programs are on GitHub or other repository sites. Then I think I know nothing about Linux.

GitHub thing is beyond my comprehension so I asked if there is specific language for that

@PrabhjotSingh I'm not sure what you mean. But if you have specific difficulties, ask specific questions. Preferably on the site.

Upon your query on my accounts, I have fixed it

or make it even better :)

rsync is part of Ubuntu.

@FaheemMitha I want to install postgresql. But don't know what to do. Site of program is git.postgresql.org/gitweb/?p=postgresql.git

@Tim Actually, I now just see "The Great Outdoors". Also apparently not linked to the other two.

@PrabhjotSingh Use the package your distribution provides.

With your package manager,

In Fedora package manager there is no program

@PrabhjotSingh I don't understand what you mean. It used to be yum. Now it's something else, I think. I forget. Check the documentation.

Or just do a simple Google.

A quick search tells one that the Fedora package manager is DNF.

Not the most memorable acronym.

@FaheemMitha Right. Unlike "apt" which is soooo memorable?

:P

Yup this is dnf. You rock

@terdon On the contrary, the name apt is extremely apt (as in appropriate), because it's... apt (as in useful).

The program apt is apt, I mean.

For your entertainment and edification, usage of the word apt.

@Tim rsync is a file copying utility. It could be used for primitive backups, but does not do compression, encryption or deduplication. It is also unsuitable for copying files to certain types of filesystems, like some Windows filesystems that does not preserve all the information that are needed to do a proper restore, or even some Unix filesystems for that matter (I'm thinking about doing off-site backups to some remote generic disk).

A backup tool could possibly use rsync, but rsync in itself is just a glorified scp.

@FaheemMitha what is that chart?

@PrabhjotSingh What chart?

@Kusalananda Like rdiff-backup. Though I don't know if it actually used rsyncor some of the underlying libraries.

@FaheemMitha rdiff-backup uses librsync, so it's not using rsync directly, but its underlying library routines.

... so, yes.

@FaheemMitha The very "apt" chart that you linked to, presumably.

@Kusalananda Chart? What chart?

@Kusalananda Yes, I vaguely recollect something. Isn't rsync C under the hood? As I recall, rdiff-backup uses a Python wrapper to some rsync library.

Haven't seen Anthony around much recently...

@FaheemMitha here is a chart at books.google.com/ngrams/…

I hate matlab. I am trying to run an old version and apparently it is built against a bunch of old libraries which I cannot (easily) install on Arch. I may have to create a chroot with an old version of Debian just to get the damn thing to run. Stupid.

@StrongBad Might even be simpler to set up a VM instead. I assume R isn't an option?

@Kusalananda Oh, you mean the ngram. Forgot about that.

Hey @terdon. So, was having a chat with Stephie in the Frying Pan.

She had her own coffee suggestions.

Oh?

@terdon I need OpenGL and GPU processing stuff, so I think a VM is out. This stuff depends on the old version of Matlab so octave/python/R and everything nice is out.

:(

@terdon I don't know if you are in that room currently. Should I summarize?

Lenny, I got to back to Lenny. Yeah, time to go see if debbootstrap even works that far back.

@FaheemMitha what is that chart books.google

@PrabhjotSingh Sorry, don't follow.

@StrongBad Why do you want to go back to Lenny?

@FaheemMitha because matlab doesn't know how to write good software. The code I have only runs on an old version and that version is linked to really old libraries.

@FaheemMitha Nah, read the transcript. Sure, pour over is fine too. Frankly, you're overthinking this. If you're not willing to pay a lot of money (which is fair enough) just get any cheap one. So any of french press, pour over or whatever.

@StrongBad That sounds rough. You have Matlab code you need to run?

There is a chart at books.google.com/ngrams/…

@PrabhjotSingh Yes, I see it. So?

:44691266

@terdon Even at the cheap end of the scale, not everything is created equal. And overthinking is my speciality.

@FaheemMitha something ngram

@StrongBad Sorry, wasn't paying attention.

So, why are you trying to run Matlab again? I assume this is not pure masochism?

If it is, I recommend a nice flail. It will be more fun.

@FaheemMitha because that is the code I have (have been given by a collaborator) and even if I have to resort to installing Windows, it will be easier than rewriting the uncommented code.

@StrongBad I was afraid of that. I suppose it's useless to sit your collaborator down and gently reason with him?

@FaheemMitha i wanted to know what this chat is all about?

There are plenty of non-horrible languages and scientific software out there. He doesn't have to use Matlab.

@PrabhjotSingh Nothing. I was just rambling on, as is my wont. terdon was casting aspersions on apt, I think.

@FaheemMitha the code is built upon code which is built upon code from a day when the choices were C/Fortran or matlab. Maybe Labview was around, but there was no R or Python.

@StrongBad Well, my sympathies. Are you saying the current version of Matlab only runs on Lenny?

Okay, I thought you want me know this.

@FaheemMitha no, the code only runs on an old version of matlab which does not run on an updated Arch system, so I figure I need to go back to the recommended version of Linux for that version of matlab to get out of the library version hell.

What do you know, debootstrap does not go that far back. Time to see if I can download an iso image of Lenny.

@StrongBad Can't you update to a more recent version of Matlab?

That would be my first move, personally. And isn't Matlab code backwards compatible?

Did they change the language? Or are you running some weird binary libraries?

Do I need SSH for using my email?
