@FaheemMitha I've only used OfficeJets (inkjet) recently, and also much more expensive HP lasers.

@FaheemMitha no, they work fine with amd64 cups

@FaheemMitha I tried the Brother drivers, but ultimately went with the open source ones

@FaheemMitha ignore their instructions on installing them, instead set up multi-arch and the dpkg -i

I don't know anything about their SANE drivers, as the Brother we have is a printer only.

I think if I were getting a new MFD, and actually printed a fair bit, I'd get an Officejet 8600.

Faheem Mitha

7:00 AM

@derobert Ok, thanks for the feedback.

I'm going by the amazon reviews. The reviews for the Officejet 8600 aren't that good. It is available in India though.

Also, I don't really want a color printer.

(181) out of 820 Reviews are 1 star. That is like a 20 percent.

NFS: You are dumb.

Faheem Mitha

7:59 AM

@tylerl ?

tylerl

@FaheemMitha I'd say it's pretty self-explanatory.

Faheem Mitha

@tylerl not really. are you talking to someone called NFS? Or are you berating a filesystem, and if so, why?

tylerl

@FaheemMitha NFS the shared filesystem. If you use it, you, too, are unhappy with it.

Faheem Mitha

@tylerl Fortunately I don't. But I thought people tended to use alternatives like AFS now. Though I doubt that is perfect either.

derobert

11:27 AM

@FaheemMitha I'm not sure what to think of that. amazon.com/HP-Officejet-L7680-Color-Printer/dp/B000MANW30/… ... I have a 7650, which is basically the same thing (it probably included different accessories in the box).

So I'm not sure if I got lucky, or if people on the Internet are idiots. (I purchased it locally at Costco, so if it was defective out of the box, it would have just gone back)

slm

12:01 PM

@tylerl I've used NFS and still do daily, what aspect of it is "dumb"?

mikeserv

12:13 PM

@slm don't question...

just "dumb"...

Faheem Mitha

2:10 PM

@derobert I

@derobert I've found amazon reviews, in sufficient quantity track pretty closely to the facts, so I tend to rely on them heavily. Of course, people can be idiots, but if there are enough people saying the same thing, then it is a good idea to pay attention. Maybe the hardware in your printer is different or maybe you indeed got lucky. Sometimes the hardware can differ even if the model number is the same.

derobert

@FaheemMitha Its possible there were multiple hardware revisions... Those reviews have a weird mix of people who are quite happy with it (I guess like me), but we're the minority.

Faheem Mitha

@derobert Yes, it could be a bunch of production runs, some of which may have been defective. there seem to be consistent complaints about the paper feeder thing, though.

plus apparently b/w doesn't print unless all the print cartridges are non-empty, which seems pretty wacky.

derobert

The ADF for the scanner can be a little finicky. That's the only paper handling issue I've ever had with it...

Black and yellow share a print head, so I'm not that surprised it won't print with missing colors.

Faheem Mitha

As I said, I've found Amazon reviews relatively reliable, so I tend to depend on them heavily. I guess you don't?

derobert

Normally they are pretty reliable...

Faheem Mitha

2:17 PM

@derobert Yes, I think that is what people were complaining about. is the document feeder for printing different from scanning?

derobert

yeah, different from printing

the one for printing has never given me any trouble. The one for scanning doesn't like scanning both sides of damaged paper

Faheem Mitha

In the case of these printers, there are hundreds of reviews. when there are like 10 or 20, there is too much statistical noise for them to really be useful. i usually look at the one star reviews first. if there are a lot of them, and assuming they are not written by morons who are complaining about stupid things, that is a pretty big minus.

@derobert I see. What do you do in that case?

derobert

manually put the document on the scan bed

but since you already have a B&W printer you're happy with, it sounded like you were just looking for a scanner

Faheem Mitha

@derobert The brother printer I mentioned earlier has got consistently good reviews, and even the one star reviews are at least some of the time just about stupid things. i don't like the fact that it is so cheap, and also Brother's wacky deb drivers are a bit of a cause for concern, but unless i find something better i'll probably go with that.

@derobert yes, and a copier too.

The other thing is that buying electronics in India is relatively expensive, so one can't be quite as casual about it as one can in the US.

the brother printer in question is like $ 100 on amazon, but closer to $300 on amazon.in.

which is annoying, of course.

derobert

wow, wonder why so much different...

you get nice laser printers for $300 here

Faheem Mitha

2:22 PM

standalone scanners are a good choice in general, but i can't find anything reasonable locally.

@derobert i don't know. partly import duties. also the list price for the brother is closer to 200, so maybe they aren't offering the discount here.

@derobert Yes, I've bought them. I'm currently using a Samsung B&W printer, which works quite reasonably.

Though I'm a light user.

derobert

I think Canon is the other big brand of MFDs here.

Faheem Mitha

@derobert Right, but not so well supported by linux.

derobert

Depends on the model. Some of them are...

Faheem Mitha

Ok. Anyway, where do you get your product reviews from, apart from amazon. i think newegg has detailed reviews too. of course, they don't have as extensive a selection as amazon.

derobert

For printers you can often find professional reviews.

Faheem Mitha

2:26 PM

@derobert If you have any specific canon suggestions i can look them up here. but I spent a while yesterday on amazon.in and didn't find anything.

@derobert Do you find those useful? I like user reviews in bulk, because they reflect a variety of experiences.

derobert

Also, Canon != US has binary drivers for Linux for a lot of their printers. If you're OK with the Brother ones...

Faheem Mitha

@derobert Well, not ok, but I guess I can live with that, if I have to.

derobert

@FaheemMitha Well, they're useful for different things—e.g., they'll have a much better idea of the cost-per-page, or things like that.

Faheem Mitha

@derobert Yes, that is true.

derobert

I have a Canon MX922, it prints, haven't tried scanning with it yet

Faheem Mitha

2:28 PM

Well, off to dinner. If you have any thoughts or suggestions, throw them my way.

@derobert Not available on amazon.in.

derobert

I got it mainly to print CD/DVD/Bluray labels. Of course, haven't gotten that to work from Linux yet.

And the Canon UI sucks compared to the HP one :-/

Faheem Mitha

junglee.com/Canon-Products-MX922-Wireless-Printer/dp/B00AVWKUJS

Rs. 32000. the dollar is currently around Rs 60.

derobert

Wait, that's ~$500 ?!

I surely would pay nowhere near that! I paid a bit under $100.

google.com/search?q=32733+INR+in+USD+%3D ... wow, indeed, $550...

Faheem Mitha

3:19 PM

@derobert yes, prices of electronics are ridiculously inflated here.

Partly import tariffs, like I said. Though, as far as I know, India doesn't actually manufacture printers. Unlike China, say. It might manufacture computers. Not sure. But I'm sure if it did, they would be crap.

The other issue is that lots of things are simply not available here. I had a hell of a time putting together a linux-compatible computer last year, because i couldn't find a decent linux-compatible mb which was available here.

What's so broad about this? unix.stackexchange.com/questions/131994/…

anybody?

slm

Guys if ppl are asking homework Q's it's kinda OK so long as they're asking us to help and not do.

mikeserv

Yeah.

slm

Everyone has to start somewhere and sometimes ppl just don't know how to start a problem.

mikeserv

And really, who cares if they ask us to do it? If you don't want to do their homework, well, don't/

slm

right

mikeserv

4:55 PM

I like those questions because because the more we answer them the less they get asked...

slm

we've closed ~2-3 of these today if my memory serves me. I hate to discourage ppl who are attempting to learning something which they don't know.

We just want to make sure we don't give them complete examples, if possible, the point should be to help them grow as a user of Linux etc.

mikeserv

I saw it a lot yesterday night, too. We're not the homework police...

slm

yes that's why I felt the need to say something, it comes up from time to time, we're here to help first and foremost, if you don't want to help someone w/ these types of Q's simply skip/ignore them.

mikeserv

That one in particular was a good question, homework or not,.

My hope was that someone would answer it with something that worked internationally - I wanted to learn from the answer.

It's not gonna happen now.

slm

Yes so let's not beat up every newb that asks a susp. looking homework Q

That one was closed for lack of details would be my guess. If you want you can expand that one and we can reopen it

mikeserv

5:01 PM

Yes... work....

But it

slm

It's a good Q at it's core, just lacking in specifics from the OP, but it would be good from the standpoints you mentioned

mikeserv

it's already plenty detailed.

slm

I didn't VtC so just my $0.02.

mikeserv

I know.

Umm...

Let me look at it again.

better...?

I don't wanna change the meaning of the question, so I just rearranged a couple words...

Braiam

@mikeserv I closed it on the basis of this meta.stackexchange.com/a/10812/213575

mikeserv

5:10 PM

That post begins... "This is not the official position..."

Also how do you know it's homework?

I see all kinds of posts where people don't even ask anything.

I want to do...

Braiam

@mikeserv but it is a guideline, and I don't care about if it's a homework question, I voted unclear

mikeserv

Ok, so what's unclear?

Braiam

final goal

> Can someone demonstrate with examples of how I might do this in the shell?

is not a goal

is a "just post the first get to your mind"

mikeserv

It's not? That's my edit, by the way.

It was before... Dang, I forget..

I thought questions were supposed to be open-ended - not yes/no.

Braiam

@mikeserv nope

mikeserv

5:16 PM

So yes/no?

Braiam

they aren't supposed to be open ended discussions

mikeserv

Not discussions - but open-ended.

Braiam

define open ended in a way that it doesn't boil down to discussion or gathering opinions

mikeserv

And it's "just post the first get to your mind" that works...

Well, the question we're talking about is an excellent example.

The goal is a shell script that will get a random letter between a-z and compare it to an input letter and say "correct" if the comparison matches.

Not - how do you feel about a-z?

Braiam

you are still not convincing me to reopen it

mikeserv

5:19 PM

Ok. But you still haven't said what is unclear about it.

Braiam

I said already: well defined goal/propose

mikeserv

The goal is a shell script that will get a random letter between a-z and compare it to an input letter and say "correct" if the comparison matches.

That's pretty well-defined.

Braiam

@mikeserv no, that's just what the script is supposed to do, not why

mikeserv

Oh, you wanted philosophy?

Braiam

no, I wanted an objective

mikeserv

5:21 PM

The goal is a shell script that will get a random letter between a-z and compare it to an input letter and say "correct" if the comparison matches.

Braiam

we are going in circles with this argument

mikeserv

I agree.

The goal is well-defined.

If you need to know why someone has a goal...

Well, I dunno how to answer that one.

@Braiam - is that what you are saying? You need to know why someone has a goal?

Braiam

@mikeserv yeah, most of the time people has the wrong approach to solve problems

mikeserv

That, I think, is an extremely opinionated statement.

Still, maybe, then, a more philosophical forum would suit you better?

And besides, even if the person asking this question is asking for the wrong reason, there are probably others that could use the answer for the right reason.

@Braiam - Can we agree on that last, at least?

Braiam

I think MJD describes better my position here perlmonks.org/?node=XY+Problem

mikeserv

5:33 PM

Oh, gods.

Ok, so, even if the person asking the question asks for the wrong reason, there are probably others that could use it for the right one, right?

Braiam

if you don't like it, your problem, I don't like those kind of questions in the site, and for my part it will stay closed

mikeserv

And I hate that X-Y thing... It feels so... stuck-up or something.

You are entitled to your own opinion of course. But can we at least agree on this last - "even if the person asking the question asks for the wrong reason, there are probably others that could use it for the right one, right?"

@Braiam...^^^?

@Braiam And more than that, I'm fairly certain you've just said you voted to close the question because you assume the asker asked it for the wrong reason. Is this true?

...*crickets*...

Braiam

5:53 PM

@mikeserv I'm not going to read above but I know those kind of question hurts the quality of the site since it gives the "we write the code for you"-kind of vibes about the site, those questions hurt us and I don't want them on the site

as simple as that gets

mikeserv

You're not going to read above?

@Braiam - I'm fairly certain you've just said you voted to close the question because you assume the asker asked it for the wrong reason. Is this true?

If it's a bad question you downvote it.

If it's outside the site's scope you vote to close.

@Braiam - These are two different things.

So I'm afraid your as simple as it gets is a little too simple. And that kind of thinking hurts the quality of the site.

@Braiam???

Braiam

6:14 PM

@mikeserv who told you that was the sole reason?

mikeserv

@Braiam - you said you voted to close it because you assume it was asked for the wrong reason.

mikeserv

6:43 PM

@Braiam - no comment?

mikeserv

6:59 PM

@Braiam - I just noticed the meta question you referred me to was closed as off-topic! How's that for irony!?

mikeserv

8:16 PM

whatever happened to goldilocks?

Aljaz

hey guys & ladies.. I need some help with process substitution.. can someone help me please?

mikeserv

Yes - don't use it.

Aljaz

haha :)

I don't have an option..

mikeserv

There's nothing you can do with process substitution that you can't do portably with a heredocument.\

Aljaz

ok.. maybe I can do that with heredoc:
I have a bash script which runs a function process_manager in a background.. there are x functions ran, and I should be able to communicate with them - send them a command

mikeserv

8:22 PM

Sorry. What exactly are you doing?/

Aljaz

I need a simple and efficient way to communicate between processes.. the main process (bash script) is reading a named pipe, and it should send the commands to process_manager - child processes

mikeserv

OK. Best way to do that kind of thing is to define the functions that need to communicate together by another function.

Either that, or a simple trap.

Gilles

@mikeserv wrong

mikeserv

No, I'm not.

Aljaz

I was trying to do that with anonymous pipes (or named pipes) // process substitution

coldattic.info/shvedsky/pro/blogs/a-foo-walks-into-a-bar/posts/16

mikeserv

8:24 PM

Anonymous pipes exist in kernel - they're one-way.

Aljaz

yeah

I found this link which shows how to do that with multi-way approach

mikeserv

Another way is named pipe - but it can lockup.

Aljaz

I tried to do it with named pipe, but when the first process will read the input, the second one won't be able to do so.. so lockup should resolve that?

Gilles

@mikeserv named pipes also exist in the kernel and are also one-way

@Aljaz you need one pipe per pair of communicating processes

Aljaz

so If I have 5 processes that should receive the commands, I need 5 pipes?

mikeserv

8:26 PM

No.

Gilles is right about named pipes.

Gilles

@Aljaz yes

mikeserv

But you don't need 5.

No - you need functions that share state.

Aljaz

@mike

mikeserv

That's all.

Aljaz

@mikeserv so how to do it with 1 ?

mikeserv

8:27 PM

Hang on.. I'm trying to find the answer...

Gilles

@mikeserv you can't share state between different processes (not in a shell script at least)

Aljaz

ok

mikeserv

You can, though.

In this answer I show how to do something like it: unix.stackexchange.com/a/125872/52934

Faheem Mitha

@mikeserv I'm with you on that one. Voting to repopen.

Aljaz

oh shit.. this is too advanced for my state of bash awareness

Faheem Mitha

8:30 PM

I don't see what is too broad about it.

mikeserv

It's not bash - it's shell.

Aljaz

can you guys help me with getting this thing done with multiple pipes?

mikeserv

Basically you just declare a function with a function.

Aljaz

like with this approach: coldattic.info/shvedsky/pro/blogs/a-foo-walks-into-a-bar/posts/…

mikeserv

Well you might also command | { declare function ; declare function ; declare function ; }

Faheem Mitha

8:32 PM

As for @Patrick's comments, plenty of people come here asking for scripts. They don't usually get closed afaict.

mikeserv

@FaheemMitha - I didn't get it either.

Faheem Mitha

I think if there is some policy it should be applied systematically. I do know on SO, questions asking for scripts do get summarily downvoted and closed.

But we aren't SO.

Gilles

@Aljaz you can't

Aljaz

@Gilles @mikeserv could you help me understand this part:

( while read line ; do
echo "$line" | grep 'aaa' 1>&100
echo "$line" | grep 'bbb' 1>&101
done;
) \
100> >( while read line ; do echo "$line" | sed -e 's/x/y/g'; sleep 1 ; done; rm $sync1 ) \
101> >( while read line ; do echo "$line" | sed -e 's/x/z/g'; sleep 2 ; done; rm $sync2 ) \
< <( for ((i=0;i<6;i++)) ; do echo aaaxxx; echo bbbxxx ; done; echo ooops )

Gilles

@Aljaz example: unix.stackexchange.com/a/128550

Aljaz

8:34 PM

echo "$line" | grep 'aaa' 1>&100
here he sends text to 100 pipe?

what does \ mean in that context?

Faheem Mitha

@Gilles are the kinds of policies i'm referencing above applied on a per-site basis?

mikeserv

It means continue next line.

Faheem Mitha

@mikeserv i'm tempted to open a meta question about this, if one does not exist already

mikeserv

Well, there's one @Braiam pointed me to, but it was closed as off-topic...

Faheem Mitha

and i don't know why a request for a script would be considered homework anyway

I think they were trying to migrate it to the general meta, but it was too specific.

there are lots of sites for which "homework" doesn't make sense, i guess. eg the cookery site?

Gilles

8:37 PM

@FaheemMitha what policies?

mikeserv

@FaheemMitha - I know. It all smacked a little too much of elitism to me.

Aljaz

how could example above be written without \ (continue to next line) ?

Faheem Mitha

@Gilles I'M NOT GOING TO WRITE YOUR SCRIPT FOR YOU.

Gilles

@FaheemMitha ??? we write scripts for people all the time

mikeserv

Amen.

Faheem Mitha

8:38 PM

See e.g. unix.stackexchange.com/q/131994/4671

@Gilles Quite. but see ^^, particularly Patricks comment.

mikeserv

@Aljaz - uhh.. Well, probably just by omitting `\`

Faheem Mitha

What have you tried so far? What are you having problems with? We're happy to answer specific questions, but what you're asking for is someone to write a script for you. We're not here to do your work for you. — Patrick 14 hours ago

mikeserv

I'm not looking super closely at it though.

Faheem Mitha

As long as the question is not gibberish (clearly written, reasonable grammar, not a lot of misspellongs), i don't have a problem with people asking for someone to write a script for them.

Gilles

@FaheemMitha this one is obviously artificial, most of the script requests we get accomplish something

mikeserv

8:40 PM

not a lot of misspellongs), makes me smile...

Gilles

still not a reason to close, only to downvote

mikeserv

!!!

Thanks, @Gilles.

That's what I said.

Faheem Mitha

@Gilles Hmm, that's a bit subjective. And we don't have a close criteria "artificial". But is that why you think @Patrick said what he said? It looked manufactured?

@mikeserv heh

Gilles

@FaheemMitha it's obviously homework

mikeserv

@Aljaz - I think your question should be a question.

Faheem Mitha

8:41 PM

@Gilles Ok, if you say so. I dunno.

He could be following along in a textbook somewhere

mikeserv

If I see it, and I think I can answer it, I'll try to weigh in.

Aljaz

@mikeserv can you please help me understanding this line:
echo "$line" | grep 'aaa' 1>&100
he's sending this to anonymous pipe 100 ?

Gilles

@Aljaz no, to file descriptor 100

Faheem Mitha

@Gilles I don't have a problem with downvoting here.

mikeserv

Well, he's sending it to file descriptor 100

Gilles

8:43 PM

which may or may not be a pipe, depends how fd 100 was opened

mikeserv

Yeah. That's not portable behavior - portably you can't refer to any over 9.

Aljaz

how would you assign file descriptors dynamically? if you had to assign x-times ?

to different descriptors of course

Gilles

@Aljaz tricky. If you get that far, you should switch to perl/python/ruby

Aljaz

what would be the best way to do that in bash?

I'm in ruby, but i have to do this in bash :)

mikeserv

printf '%d<<HEREDOC' $(seq 100) | . /dev/stdin

Aljaz

8:44 PM

what would that do ?

mikeserv

Or something like it. You'd need to close out the heredocs.

It would open a new heredocument for each file descriptor you need.

And assign it a filedescriptor 1-100.

Aljaz

ok

and could I use them for inner process communication?

~how

mikeserv

I mean, not as is - it's really rough. You'd need spaces, and to populate the heredocuments with something worth using.

Well, I did link to that other answer...

That would also make a great question, I think...

Aljaz

the link with the space-shuttle shell code?

mikeserv

Space shuttle?

Aljaz

8:47 PM

I mean advanced shell code :)

mikeserv

I think the shuttle's code was a lot less complex...

But they are simple concepts, really.

Just heredocuments and parameter expansion.

Faheem Mitha

@mikeserv I don't think the shuttle's code was in shell.

mikeserv

It's just that most people don't talk about them.

Yeah, I know.

Faheem Mitha

Maybe the one that crashed and burned. That would explain a lot.

mikeserv

That was an o-ring.

Faheem Mitha

8:49 PM

@mikeserv So they said. Shhhh....

mikeserv

OR maybe it was my shell script...

printf 't-minus %d<<LAUNCH' $(seq 100) | . /dev/stdin

Aljaz

lol

I still dont know what the easiest way would be to implement inter process communication

mikeserv

Well, you didn't ask a question either. There is IPC as well - that's in kernel. And you can use message queues.

Faheem Mitha

Anyone, thoughts about buying a multifunction printer that works with linux and doesn't suck? Extra annoyance, needs to be available in india. I'm thinking of the Brother DCP-7065DN Multifuction Printer

mikeserv

I bought a brother printer. It did suck. But it was cheaper than the ink refill.

When its ink ran out I sent it in for warranty repair.

Faheem Mitha

8:56 PM

@mikeserv Did it need repairing?

mikeserv

No - it needed ink.

The replacement they sent me came with ink.

Faheem Mitha

@mikeserv Ok. probably dumb question, but why did you send it for repairing if it didn't need repairing?

mikeserv

For ink.

Faheem Mitha

and why would they send you a replacement if it didn't need repairing?

@mikeserv Don't follow

mikeserv

They sent me a return postage-paid box for mine. And they sent me a replacement unit. I put the empty printer in the replacement box and the new unit on my desk.

Technically it wouldn't print anymore...

Faheem Mitha

9:01 PM

@mikeserv Well, they're nice of them. But I still don't understand why they sent you a new printer if your old one was out of ink. Usually one gets new ink. Was this an inkjet printer? They are a pain.

@mikeserv :-) Interesting. I must try that sometime. My printer won't print any more, please send me a new one. :-)

mikeserv

I called them and told them my printer wouldn't print anymore, they asked for the warranty date and I gave it to them. The rest is history.

Faheem Mitha

@mikeserv Wow.

I find laserjets are just less of a hassle.

laser printers, sorry.

mikeserv

I find they're too expensive. And really, I very rarely print at all anyway.

Faheem Mitha

@mikeserv laser printers?

mikeserv

Yeah.

Faheem Mitha

9:06 PM

Presumably the printer rather than the toner cartridges, though.

Q: Uninstall a python software properly

python

Faheem Mitha

@ppr It is usually not necessary or appropriate to post your question in chat. it appears in the feed.

@ppr did you try the uninstall thing? Otherwise you can just setup.py to see where it put stuff.

Or you could just run the installation again and save the output.

distutils is usually quite chatty

and no, don't try pip uninstall if you didn't use pip in the first place.

Patrick

10:49 PM

I said what I said because of http://unix.stackexchange.com/help/how-to-ask. Several of the points on that page are relevant. Namely the *share your research* one though.
Yes, we do write lots of script for people here, but one thing I think you'll notice is that many of the scripts that are written are based on what the asker has already tried. We simply massage what they're doing into something that works.
While there is no official policy on homework questions, the community is pretty clear on their opinion of it: http://meta.unix.stackexchange.com/questions/344/homework-policy-proposal

Faheem Mitha

@Patrick I looked at the help thing and the linked meta unix,sx question. The meta question does say making an effort is a good idea, but it doesn't represent any kind of policy. I think a flat question with no attempt is possibly grounds for downvoting but not for closing.

fwiw @Gilles said essentially that a little earlier here.
