@JennyD Done!

@JennyD by the way what about chat.stackexchange.com/transcript/message/26445171#26445171?

Ideas (for both `env`ing and `cd`ing):
1. /SE/U&L/26
2. /SE/U&L/Chat
3. /SE/Chat/U&L

Anyone like:?

Let's discuss for meta:

U & L policy kit

Meta is a policy kit for our site!

Jenny D

9:11 AM

@Pandya That one I like. But it's very close to what @FaheemMitha suggested (which I've also upvoted).

Pandya

9:24 AM

Note: that is room on meta.unix.SE not unix.SE

in mount /dev/chat, 11 mins ago, by Pandya

Example: Inspired by this answer, I've named this chat-room!

Faheem Mitha

@JennyD Hi. How are you doing? Having a good weekend?

Pandya

9:45 AM

@FaheemMitha Add linux to this room?

Faheem Mitha

@Pandya Pardon?

Pandya

@FaheemMitha I am talking about adding linux here

Faheem Mitha

@Pandya Why do you want to do that? And I didn't even notice that tag. Has it been there for a while?

Pandya

@FaheemMitha Because visitors will be happy to see the most popular tag of our site at chat-room

Faheem Mitha

@Pandya I really doubt anyone cares. But you could open a meta question about it.

Pandya

9:51 AM

@FaheemMitha That (on chat-room) tag are just for fun. I don't think we should have a meta Q for that.

By the way, What do you think about adding linux to this chat-room? @terdon

terdon

I was thinking of removing unix instead. I never understood the point of having tags on the chat room's description.

Faheem Mitha

@terdon Yes, like I said, I didn't even notice it was there. Has it been there long?

terdon

I think it's always been there, yes.

Jenny D

@FaheemMitha Hi Faheem! Yes, I'm good. How're you?

Faheem Mitha

10:06 AM

@JennyD I'm doing Ok. There's a frenzy of bikeshedding going on wrt that renaming question. I wasn't expecting so much activity.

terdon

room topic changed to Unix and Linux: General discussion for unix.stackexchange.com. If you have a question, see unix.stackexchange.com/questions/ask (no tags)

Faheem Mitha

I thought most people would be away on vacation. But apparently there are enough people around.

@terdon What was the original title? :-) Yes, Sherlock Holmes I'm not...

terdon

Same thing with the unix tag.

Jenny D

@FaheemMitha I think to many people it's sort of relaxing to spend time on a question that can be considered trivial

Faheem Mitha

@JennyD Perhaps so.

@terdon Ah, Ok. You took out the unix tag. Got it.

@JennyD So, how's the horsey?

Does anyone happen to know how @cas is doing? The last time I talked to him, he was planning a major operation.

Jenny D

10:10 AM

@FaheemMitha He's fine - I'm not going riding today, but I'm planning on a longish ride tomorrow

Faheem Mitha

@JennyD Ok

Pandya

By the way I found there are no question tagged with faq on meta But tag is exist, Should this tag expect questions? @terdon

terdon

?

@FaheemMitha He was seen 56 seconds ago. I guess that's a good sign.

@Pandya what do you mean?

Pandya

@terdon I mean should we have post for faq?

terdon

On meta? What would that post say?

Pandya

10:15 AM

@terdon Yes, I am talking about meta.unix.stackexchange.com/questions/tagged/faq. That seems (red color) moderator only tag

terdon

Oh. Sure. If you find a question you think should be tagged faq, flag it and let us know.

Jenny D

Do you mean that a post should be created to match the tag or what do you mean?

Pandya

@JennyD yes, something like that or tagging existing post with faq

Jenny D

@Pandya Posting a new question solely to get something into a tag seems like a waste of time to me.

Content should be posted when someone has something to say, not merely to fill up a tag.

Faheem Mitha

@terdon No, I think that's just machines talking to each other. You'll notice everyone has been seen a short while ago, no matter how long ago they talked. I think that may be how long it has been since SE communicated with the client or something.

cas seems to have left his machine running with SE in the browser. Which does suggest that he's around, though.

terdon

10:22 AM

@FaheemMitha I don't think so, no. It's not about the last time you talked, it's about the last time you were active. I think that any action (probably including scrolling) will trigger an update in the time.

Faheem Mitha

@terdon I don't think "seen" is the same thing as "active".

Look at the list of icons on the right. Notice that they have all been "seen" less than a minute ago. It's statistically impossible that all these people actually did something in the last minute.

Actually, it looks like it cycles around at about the minute mark. Presumably that's by design.

terdon

@FaheemMitha It is. It measures any activity on the site.

@FaheemMitha Huh? Impossible! I expected better from you. There's no such thing as statistically impossible and, in any case, that 8 users out of the millions on SE have been active in the last minute is not even slightly improbable. Remember that this counts activity on any site of the network.

Hi why I get black page after I install Ubuntu 14
I installed alongside win8 and when I go to Ubuntu I get black page

I get a error acpi probe failed before to get black page

Faheem Mitha

@terdon I really don't think it is the case, but we could wait for someone who knows.

Mark berg

I'm a beginner

Jenny D

10:31 AM

@FaheemMitha He posted comments yesterday.

Mark berg

Me

Faheem Mitha

@JennyD Ah, Ok. Wonder what happened with his medical procedure.

A: Account "last activity time" is not always updated

You're looking at the wrong field in your user profile. There are two dates there. Note that only one of those dates is shown to public viewers of your user profile page. Seen: equivalent to LastAccessDate. Activity threshold 30 minutes. Shown to all users. Last Activity: equivalent to LastLogi...

4

A: Is "seen" working ok?

First of all, "seen" refers to all possible user activities, not just asking questions. However for the user in question, the only activity was the question you linked to, and the slight or discrepancy is explained because of the 30 minutes activity threshold, i.e. any user activity can update "s...

3

A: What does the 'seen' field value in my profile represent?

The "seen" field in your profile displays the last time that you were "seen" on or by the site. In other words, it indicates your last activity on that particular Stack Exchange site. It changes all the time because when you're doing things on the site, it's "seeing" you. It's really not all tha...

And I can confirm having seen the "seen" times be several minutes or hours ago despite the user being shown as logged in.

Faheem Mitha

@terdon I think those questions might be talking about the main site. Not chat.

To be clear, I'm talking about the icon in chat. Not the main site page, which I agree reflects actual user activity.

terdon

@FaheemMitha I know but I don't understand why you would think that they work in different ways.

Oh. Damn. @FaheemMitha looks like you're right:

A: What does the 'seen' status tell about users in chat?

A user is marked as having been "seen" every time a chat window open in their browser polls the chat server. This is a bit misleading, since oftentimes the user has not actually interacted with that browser window for a very long time. Having been "seen" essentially just indicates that the user's...

We should therefore use the "seen" on the profile page for this kind of thing.

Faheem Mitha

10:47 AM

@terdon Right, like I said, machines talking to each other.

Though the browser updates more often than once every minute, so I'm not sure exactly how this works. And sometimes chat doesn't update at all, if nobody is talking. Maybe it's just a "are you still here" kind of deal.

Partly to test connectivity, perhaps.

> Last seen yesterday

Well, cas's profile on the main page says:

So, he's around. Just not coming in here for some reason.

terdon

@FaheemMitha Maybe he has better things to do on Christmas. I certainly hope so.

Faheem Mitha

11:05 AM

@terdon Maybe.

Suggestions for converting a doc file to text? I'm rummaging around on the net, but haven't found anything yet.

catdoc works.

Hi all, I have a php-fpm issue that I can find zero information online about, the error message is "no free scoreboard slot," I have no idea what that means and apparently the internet doesn't either.

A Google search yields one dead StackExchange thread and the source code of php-fpm...

A: php-fpm: ERROR: [pool ] no free scoreboard slot

Finally the problem disappeared after I modified one line of terrible code that tried to fetch all records(sometimes up to 10K) of a table from MySQL. I checked nginx's access log, and was surprised to find that many requests to an api yielded 500 response code. After some digging, I found it's...

mm... seems like a exhaustion of some resource

Guillochon

6:09 PM

Yeah that's the thread. But there's no real answer there.

I do see that PHP-fpm processes are seg faulting every once in a while, and PHP children respawn to replace them, the problem is that at some point the children stop respawning, and then the server becomes unresponsive

There's some pretty old Wordpress code in use so I'm not surprised by the seg faults, I just want the server to be robust to those.

Braiam

6:27 PM

did you check your queries?

Guillochon

@Braiam Even if I have a bum query, shouldn't the server not entirely die? It should just kill that process...

Braiam

well, if it does then it is a bug

Guillochon

@Braiam I'm also not sure how to dump the problematic query to a log, it seems like all I can dump is when a child dies, not what causes it to die

Braiam

nothing can we do about it, right?

Guillochon

@Braiam It's kinda a crappy bug though. The only way I can see around it is to auto-reload PHP-fpm when it stops being responsive through a cron of some sort.

I have a feeling it's a memory issue of some sort, this is on a VPS and I know it does funny things when it gets close to the RAM limit

Q: Rate Limiting Individual URL Requests

I have a Flask application I’m developing that relies heavily on external website interaction and is initiated by the end-user. If I leave the application without any sort of bandwidth control/rate limiting then this application may be abused by actors with nefarious intentions. My goal is a ...

Is this question better suited for ServerFault or am I at the right place?

Braiam

11:35 PM

@RyanFoley you are using linux, why not?

btw, and HTTP proxy might do the same and be easier

Ryan Foley

11:56 PM

@Braiam Stacks usually have distintly different Q&A guidelines so I'd rather ask than be stuck in purgatory indefinately. Coming from the NetEng SE, I'm familiar with frequent migrations because things don't fit perfectly. FWIW, my questions was questions which is the best place, versus the right place.
