@faheemmitha the thing I like best is the $100 credit I got for having a .edu email address.

Faheem Mitha

@casey Credits are nice.

casey

12:26 AM

@faheemmitha very easy setup, ipv6, PTR records reverse DNS. Scalable plans from $5/month. No complaints from me so far.

Faheem Mitha

12:59 AM

@casey Ok. The current plan I have for ramnode is $5 per month. How much are you paying?

Faheem Mitha

1:13 AM

@derobert remember this one? bugs.debian.org/744275

According to Norbert, there was "no bug here, just abuse of the system". He fixed it anyway. Without further explanation.

casey

@faheemmitha I have the minimal plan. 1 core, 0.5 GB ram, 20 GB ssd storage and 1 TB transfer. Billed at $0.007/hour to a max of $5/month.

Braiam

@FaheemMitha Debian must have good reasons to break backwards compatibility

Faheem Mitha

@casey Do they freak out if your VPS goes haywire and starts running at capacity for no reason? Or has it never come up? I took a look at the DG terms of use. Quite disturbing. Though I can't recall if I've looked at the RN one. Maybe just as bad.

@Braiam What?

casey

Haven't run into that.

Faheem Mitha

@casey ok

casey

1:20 AM

For big jobs I'd probably go with Google's compute engine. At least for the jobs I can't run on Yellowstone.

Faheem Mitha

In blog.flameeyes.eu/2009/10/a-shared-library-by-any-other-name it says "uses the NEEDED entries in the .dynamic section of the ELF file". Any idea how to look that up / query that?

@casey Sure. How much does that cost? What service is that?

objdump -x works. possibly overkill

1:36 AM

@casey Thanks. The pricing looks relatively reasonable.

Braiam

1:11 PM

@derobert rename it to format-command?

casey

2:37 PM

@FaheemMitha yep, I'd call it reasonable as well. It would cost me on the order of $2.50 to run one my simulation cases on google compute and $3 or so to download the data. For 100 cases that would be $550 and I'm sure the grant award for yellowstone values my awarded core hours at much more than that for the same amount of work / transfer.

Faheem Mitha

@casey Probably true.

casey

especially since just applying for compute time on yellowstone in general requires you are funded on an NSF grant in the first place. High barrier to entry.

casey

3:01 PM

and oops, I only estimated my cost with 16 cores and the runtime of 64 :) It would actually cost me $10 to run a case and $3 to transfer the data. So $13/case and $1300 for 100 cases. Still not too bad.

4:02 PM

Are you by chance using a machine translator? Is impossible to understand what you are trying to do or how. — Braiam 15 mins ago

that was my thought as well

derobert

4:14 PM

@casey Well, the omnibus installer can be configured to play nice with some other things, e.g., to use a system postgres instance or nginx instance, I think. It looks like otherwise it mostly stays out of the way.

@Braiam I guess, though I think that'll be the only instance of said tag.

Also of course unfortunately generic... I suspect there are other, unrelated, format commands out there.

I just struck it off.

Gilles

4:43 PM

@derobert that question isn't about the format command, it's only the way the symptoms were revealed. The next step is to blacklist format and make it show guidance. ping @terdon @slm to finalize the disambiguation text and pass on the request to devs.

Braiam

btw, anyone can make sense of the motion, navigation and selection?

casey

@Braiam accompanied with vim, motions refer to ways to move the cursor and some normal mode operations

terdon

@Gilles On it

Braiam

@casey the thing is that was created for camera motions

derobert

@Gilles Ah, OK. I have no idea what the Solaris format command does.

Anyway, there are now no longer any questions with format

slm

4:52 PM

@Braiam motion is an application that you can use to capture video from a camera.

I've A'ed several Q's about it:

unix.stackexchange.com/search?q=user%3A7453+motion

derobert

@slm If we're going to use motion for that, it needs cleanup + a wiki

(And yeah, I think vim is enough for vim motion keys.)

casey

@derobert agreed

I only commented on vim because they were the top hits in that search

derobert

I just retagged the vim motion questions. All of them as just vim. Took off some other silly tags as well, like navigation

navigation is now 0 questions.

@slm I put in a tag wiki excerpt... but that's from reading the first paragraph on what I think is the program's web site + a little guessing on my part .

slm

@derobert -OK, I was working on those I'll see what you wrote first.

I updated the tag wiki @derobert

derobert

5:24 PM

@slm I guess I did a good job writing it for 3 minutes of reasearch :-/

slm

5:55 PM

@derobert - good enough 8-)

terdon

6:19 PM

@derobert @Gilles @slm format is now blacklisted and a warning giving alternative tags is shown.

derobert

@terdon cool, tested it here and it works

My next goal is server:

Q: Burninate [server]

In theory, the tag server is about a computer program running to serve the requests of other programs or a physical computer dedicated to running one or more such services. The first meaning (a computer program) is a useful one: there are many questions about server programs. The second mea...

6:44 PM

I cant decide if I'm getting a new form of spam or if someone signed up for some dating website and mistakenly used my email

terdon

@casey I see very little difference between the two.

casey

every few days its a new email (to my gmail acct) of the form "Hi, I'm <name> from converse, tx and saw your profile on <some site>, lets be fuckbuddies!" and 2 or 3 rather explicit attachments (jpg)

terdon

@casey I bet your wife appreciates that.

casey

I already get enough shit for the ads on tpb when she asks me to get some tv show for her :)

particularly the "better than craigslist!" ones

I reassure her "there is no craigslist for midland, and I'm not driving all the way to saginaw for that!"

terdon

Ramesh

6:55 PM

8 hours to set up samba,wow.

slm

@Ramesh takes like 10 minutes

ridiculous

@Ramesh - you got my last vote of the day

Ramesh

@slm yeah. That's why I gave how to setup samba as an answer though the OP did not want it.

@slm ha thanks. But how do we know if we run out of votes?

Will we be notified?

slm

when you get down to 5 left it warns you that you have X left every time you use one

when you get to 0 left it notifies you via a flash on the screen where you just voted

terdon

@slm That's so annoying.

slm

@terdon - na, I've gotten used to it 8-)

@terdon - sorry didn't weigh in on your Q, been busy today

terdon

7:01 PM

@slm Which? The one about the blacklisted tag? No worries, I just wanted to give you the chance to.

slm

yeah, didn't really have anything to add anyways

I think it makes total sense to blacklist certain tags

casey

@casey It's practically obligatory to downvote this. I did. I wanted to write "DIE, SPAMMER, DIE!" as a comment, but restrained myself.

let see if charter sends me any email over this 1.5 TB download I just initiated. sustaining ~60mbit/s so far.

Ramesh

This comment is good..

It's like soliciting product placement. "I can answer this, but first, I need some coca cola to go with my little debbie's oatmeal pie.

So, you asked about Integers..." — Plutonix yesterday

Faheem Mitha

Hey @Ramesh

wenzul

hey, i never used this chat. just put questions to discuss here? (or never ask to ask?) :)

Ramesh

@wenzul Questions go in the main site. But yeah technical things could very well be discussed here.

casey

@wenzul you can discuss just about anything in chat including questions, but do post the actual questions on the main site rather than asking in here initially.

wenzul

8:52 PM

yep it was already asked

I want to shutdown my server via a webpage

I know I have to secure the whole thing and protect it against clicking by accident

there is a ubuntu 14.04.1 server, and a python webapp running

so my suggestion is create a shutdown program with setuid and call it or write a file and listen for it via inotify or I could use the sudoers file

so are there any more solutions for this? and what do you think is the best effort of usability and security for this?

terdon

@wenzul where's the question?

wenzul

The question is written in the last line...

casey

@wenzul he means "link us to the question you asked on the main site"

that you are discussing with us

if we answer you, it'll be in the Q, so that it benefits everyone, not just the 4 of us currently active in here

wenzul

ah ok sorry, i didn't know that

Q: how to shut down a server from the webinterface

I have a not stationary server which runs a python web application. The server runs Ubuntu 14.04.1 64 Bit. The webserver won't run as user root. If I connect the device to the power supply it boots immediately. If I disconnect power I don't want to log in via ssh and execute a poweroff command. ...

ubuntu python shutdown webserver applications

thank you for help me getting familar with this chat :)

terdon

9:08 PM

No problem. We did kind of mean whether you've asked a question on this site, not another one. Never mind though :)

@wenzul I suggest you edit your question and explain what you mean by "a not stationary server". Also, what is this device that boots immediately? Why would you need to log in via ssh after disconnecting the power? For that matter, how could you?

wenzul

@terdon Ok I will try to fix that...

wenzul

9:27 PM

@terdon Made an attempt

terdon

@wenzul What difference does it make whether the server moves physically? As far as I can tell, you just want to know how to shutdown a Linux system via a python script running through a webpage. Is that correct? If so, everything else is irrelevant.

Oh, and @wenzul, this is an apache server right?

wenzul

@terdon Yes that's right. I just wanna be sure that nobody is writing press the power button it will shutdown then... I will remove it

@terdon It's not clear now. I read wsgi is not that good option for python. So maybe Gunicorn but I have not investigated yet

@terdon I compressed it a bit...

terdon

@wenzul I posted an answer. I really don't understand why you would want the unavoidable risks of having a web interface for this but that's one way to do it.

wenzul

@terdon Thank you. I want not to avoid it, I just want to impement that in the most restrictive way...

@terdon I think give a webuser rights to shutdown the server is give a webuser the right to do that...

terdon

9:43 PM

@wenzul Well, yes, of course. Whatever you do you are going to allow anyone who can access that page to shutdown your machine.

What makes you think that opening a browser, going to a webpage and clicking on a button is faster/easier/simpler than just running shtdn from a terminal? Hell, you can even have a little icon on your desktop that does that when you click on it.

wenzul

@terdon sure... but the users and machines will change. If that would be just for me... yes would use that.

@terdon Got my point? Ok thank you, I will look into your suggestions.

terdon

I am not a security expert but it seems to me that as soon as you have a web page that can shut down the computer, the only relevant security is that of the webpage and not of the program it is running. I would ask on Stack Overflow or Information Security how to go about making access to that page as safe as you can.

wenzul

@terdon ok thanks

slm

10:38 PM

@Ramesh that comment is awesome!

Faheem Mitha

I see that answer cracked -200. I think we should shoot for -1000. That's a nice round number.

@terdon got a minute? I've got a problem.
