Just discovering the fstrim command. Something new every day.

Hey there @ewwhite. I hear you talked to my manager today about working for our team :-)

So I'm restoring an 8TB array from backups and now I'm really regretting my policy of "just keep it, we're not exactly low on space" as I saw a backup of an ESX (not even ESXi) install media come through

It's restoring at 150MB/minute so every gigabyte counts at the moment

@ewwhite that was me :-p

@JoshGitlin so I hear!

Thanks for the recommendation.

Sure thing, thanks for all your help here on SF :-)

I originally wrote that I have no dev skills.. I'm pretty not-devop

@JoshGitlin how has the transition been for you? How was the move?

@JourneymanGeek I just got another delivery of Intel NUCs and I can confirm that these have a 2.5" WD Blue in them

@MarkHenderson: 0_0

Delivery? And I think they don't come with em stock

@JourneymanGeek They don't, our VAR added them for me

Mind if I ask what you're using them for?

ahh

@ewwhite Transition was fine. I moved cross-country from North Carolina to Seattle. I did a self managed move, they gave me a healthy relocation bonus. But I hear the managed move is really awesome, it just didn't make as much sense for me

@JoshGitlin how's the on-call schedule been for you?

So far I am really enjoying the team. And so far it's been 99% ops, not much dev at all

and bleh, I need my results soon, I've started applying for jobs, but it would be easier with my degree

and my mom keeps handing me job ads for "finance assistants" and wierd shit like that

I'm always afraid of firms that build their own tools to that extent... e.g. no puppet/chef, but a homegrown configuration management framework. Have you gained anything @JoshGitlin

@ewwhite On-call has been great for me, because I was coming from being on-call 24/7 by myself. So having a secondary and being on-call only 12 hours a day ina weekly rotation is much better

I only got paged twice last weekend

@JourneymanGeek Sit them behind a 42" TV for web conferencing

ahh

@ewwhite Yes, everything we have is homegrown. Very powerful, but there's definitely a learning curve. (Can't talk about it, under NDA :-)

And one of them I'm going to experiment with making it a tiny domain controller at a remote site

Yeah, they're lovely machines for that sorta thing

Which processor?

Celeron N2820

So really basic stuff

4GB

(And if anyone else is interested in doing ops for Amazon in Seattle, let me know. My team is actively looking!)

The test one I bought works brilliantly

@JoshGitlin I'm likely unqualified... :)

@JoshGitlin Only US region?

@MarkHenderson Yes. Seattle, WA

Aww :/

sorry @JourneymanGeek!

@JoshGitlin: Tis ok ;p

And Dublin!

I'm stuck here for now

(I've applied to facebook, local supermarket, and local pension-ish find so far. Still looking)

That's true, we have a Dublin team too. But that team has more members than our Seattle team. So it's SEA that's looking for engineers

@JoshGitlin I just got back from Seattle. Tough town.

@ewwhite If you do the phone screen we'll find out :-)

A bum pissed on my leg.

Ha! That's no good

@MarkHenderson: Its passively cooled, insanely efficient, and probably would handle anything not gaming.

I'm enjoying Seattle so far

@ewwhite It was probably Steve Balmer not knowing what to do with himself any more

@JourneymanGeek Exactly

And the 1MB of L2 cache hasn't proven to be inhibitive yet

@JoshGitlin What were you doing before Amazon?

I was self-employed. Web software developer who was asking questions on ServerFault to make sure I keep my servers up ;-)

@JoshGitlin was business okay?

@ewwhite The business is still around, I had a business partner.

@MarkHenderson: I'm not entirely sure I've come across a situation where I was aware of being held back by cache

@JoshGitlin And you're allowed to continue with it?

@JoshGitlin When are we meeting up :P

@JoshGitlin oh man.

@Jacob I was primary on-call last week. It was crazy. Things were on fire :-p

This week?

@JoshGitlin: literally?

@JoshGitlin Sure, when?

@JourneymanGeek No, thankfully :-)

Without getting into detail (because I can't) I'll say that kernel bugs causing machines to lock up cause major headaches and lots of work for sysadmins

That's a sufficiently general statement :-)

Oh, NDA's...

I totally disclose everything

:)

Yeah, I can understand that

@ewwhite To us ususally

@MarkHenderson Oh, I can't do that anymore. Iain will get salty.

@ewwhite meh

I like your full disclosures

They make me feel better about my clients

I'm keeping it to myself...

things ain't bad right now.

Any Comcast EDI customers in the house?

@EEAA EDI?

It's their business-class fiber product. "enterprise dedicated internet" or somesuch

@EEAA I know of Comcast Extreme 505

505Mbps

and I'm on the Extreme 105 (105Mbps) product

I don't think that's available here

and I have plenty of customers on the business cable.

is that fiber or cable?

the business cable is delivered via fiber in Chicago.

but the Extreme 505 is fiber. Extreme 105 is DOCSIS

the reason I'm asking is that I'm working through getting them to turn up IPv6 on my circuit, and I just got an email from my rep saying that they only allocate a v6 /126.

...which is completely ridiculous

I get a /64 delegation at home.

I was just curious if anyone else has had to work through this with them in the past.

@EEAA those numbers don't mean anything to me.

the v6 address space is 128 bits, so a 126 netmask is only what, 4 addresses. Standard practice with ipv6 is to allocate at least a /64 to each customer.

@EEAA Tell your rep to kindly put down the crack pipe.

@MichaelHampton Yep. I'm hoping that he mis-spoke and that the /126 is just for my end of the routed P2P link.

@EEAA That's what a /126 is generally used for. So I expect he misspoke because he's a sales rep and doesn't understand the product...

well, he's supposed to be the technical sales guy. I have another non-technical sales guy as well. Ugh.

Comcrap gives me a /60 on my residential class connection. If they aren't giving you at least a /56 then something is seriously wrong.

Yah, I'm requesting a /64 and they give it to me. I should change that to /60 and see if it works. It probably will.

...that's on my home connection.

Eh? You need more than a /64 unless you have a very small network.

And I'm using nearly half the /60 at home already...

@MichaelHampton Filthy, wasteful, IP-squandering bastard.

I have a very minimal setup at home. Too many years of dealing with too much crap in the house.

@voretaq7 I'll have you know I planned my subnetting very carefully! I gave my girlfriend half of them.

@MichaelHampton Is there any downside to using the "fstrim" command?

@ewwhite None that I know of.

@MichaelHampton . . . bitch can get her OWN damn addresses! IPv6!

@MichaelHampton so I can totally run it on a busy client right now?

@ewwhite Well, I don't know about that.

lsblk -o MOUNTPOINT,DISC-MAX,FSTYPE | grep -E '^/.* [1-9]+.* '

@MichaelHampton Careful, if you break up she might get to keep them

@MarkHenderson Yeah, but I still have a tunnelled /48 to fall back on

# fstrim -v /pprotest/
/pprotest/: 218210217984 bytes were trimmed

Got Backups?

zfs snapshots.

and a mirror server.

@ewwhite OMNOMNOMNOM - Uh... sorry did you want some of this data?

@voretaq7 You think I messed something up?

@ewwhite idunno, access your data and find out :-)

Probably not

gulp

# fstrim -v /ppro
/ppro: 501508534272 bytes were trimmed

I can't count that high

# fstrim -v /
/: 32.1 GiB (34501926912 bytes) trimmed

Hm, that happens to be exactly the amount of free space, too.

right. same here

And nothing blew up... yet.

Well, looks like comcast at home does indeed honor a /60 PD, so that's nice.

@EEAA Shouldn't you get a /48 according to "common practice"?

heh, a day before the main guy goes on vacation and I leave for the weekend (plus holiday), we're supposed to re-do February's release, which is two releases in the past.

We estimated it would be ready next Friday, which leaves zero days for QA to test it.

bad timing.

well, we're pushing back, and I'm pretty sure QA is going to explode when they're asked to set aside two weeks to do a fire drill

So when firefox hits 2.5GB of memory consumption, is that a fault of the browser or a fault of the webpages I visit?

@MarkHenderson: Probably a bit of both

Unless you're @Bob.

Morning

damn. docker is pretty simple.

G'day

%NSFW facebook.com/video.php?v=4437341788741&fref=nf

Morning

A disk destroyer /dev/zero overwrite has been going on for 30 mins, its a 15GB flash drive for gods sake

0_0

@JourneymanGeek -_-

@Nick About 8 MB/s? Sound about right.

Some flash drives have write speeds going down to 2 or 4 MB/s

I just tested a Sandisk flash drive. Writes at a little above 4 MB/s sequential.

So... yea. It'd take over 30 mins to write 16 GB.

@Bob yea, I have an adata flash drive

Havent tested the write speed on it

Usually moving files to the things looks fast because of write caching in the OS, and reading things off them is way faster as a rule than writing.

does sombody know how they get those chapter markers in the youtube video? youtube.com/watch?v=mU86ABh2N34

no idea, sorry.

@olli developers.google.com/youtube/training/player/chapter-marker

amazing what you can find just by typing things into a search engine

@JennyD Thanks, but this only talks about embedded videos... these guys did it right on the regular youtube page!

intermittent hardware faults are the tool of the devil.

Hey guys

i am trying to upgrade my PHP-mysql version

i get the following message in my PHPMyADMIN Your PHP MySQL library version 5.1.73 differs from your MySQL server version 5.5.39. This may cause unpredictable behavior.

Can anyone help me with this?

Early, but this is a great domain hack rebecca.blackfriday

0_0

those TLDs are going nuts

i bought a .pics the other week.

FUCK YOU, JAVA UPDATE!!!!

"The download failed"

very good information!

FUCK YOU, ORACLE!

how can we wipe java from this earth?

maybe we should start a kickstarter campaign to buy the rights to java and then just forbid it!

@MichelZ "Error: Success"

@MichelZ It will only be replaced by something worse.

Java was fine, and then Oracle bought it

Actually

not really

@MichelZ personally i find the adobe updates more annoying, everytime it is a different named exe..

so for every update i need to reconfigure my firewall to accept outgoing from that program for X ips..

adobe updates are made out of a lot of fail, it has to be said.

As much as Oracle suck, and I believe they've made things worse, I'm not sure I'd have ever classified Java as "fine"

@MichelZ well, as oracle is a public company(afaik) we should be able to buy their stock, get the majority of shares, and force them to public domain the whole shit.

so a kickstarter for that : i would totally back it.

@DennisNolte Id pay 10 bucks for it, thats about it :p

best way to stop people using it would be to just keep issuing it but make sure it only supported rendering text in user's choice of wingdings, papyrus or comic sans...

@DennisNolte actually, I don't think "Java" has any value for the Oracle stock... it's mostly their Database, HR systems and the like. Not the open source stuff...

So buying out java alone is much cheaper than buying the whole of oracle

@DennisNolte definitely not. Nice updater, works every time... is even intergrated now with Windows (Flash)

@JennyD WORSE than java??? now way!!!

@Nick Yep, that kind of thing... argh!

Searching for a laptop battery replacement is always fun... right?

@Nick throw it away and buy a news one. It's like buying toner for a printer.. just buy a new printer, it's cheaper :)

@MichelZ its a 4 years old laptop, found battery for 50 euros... laptop cost 600 euros :p

@Nick depends on make and model. You can get 4-year-old-laptops for free :D

@MichelZ acer aspire 5742G

got it 4 years ago for 600

I hope they paid you to use that thing

@MichelZ its not that bad

decent specs

haven't used acer much TBH

@JennyD "No" way of course... just seen the typo :)

@MichelZ I have dual boot arch and kali on my laptop to use when im not near my desktop... figured since I upgraded my desktop few months ago time to fix the battery xD

I basically use my laptop as an RDP client to my desktop

which is what i'm doing right now :D

Aaaand I just realised I have been surfing on kali as root for the past 2 hours -.-

even windows people learned not to do that

:)

@Nick madness.

The default user is root, and just finished installing it completely forgot about it :p

Apparently an apt-get update that took 30 secs lasted for 10d at 7 B/s

gg debian

@Nick yeah... lame excuse :D

@Nick tbf Kali update servers are veryyyyy slow

@LucasKauffman no thats a debian server update... it actually lasted for 30 seconds but at the report at the end it said it downloaded at 7 B /s and lasted 10 days

not that slow though

@MichelZ I take it you haven't looked at PHP...

Just had a meeting with Dell

They really send their biggest bullshitters - far from impressed

@Dan when you get the right guys, they can be great

We try and name the ones we want to talk to :-)

@RoryAlsop I don't 'do' Dell, and neither do the customer but they're buying the best part of 1000 Thin Client devices from them. Was meant to be a technical meeting with technical outcomes, but they sent a pair of pre-sales guys who were quite openly only interested in the cash side and spent half the meeting trying to find out "Who's who" to muscle in other deals, and the other half lying to me about the capabilities of their software

@Dan that sucks entirely

My favorite bit was when he outright argued with me about whether our Citrix environment was doing something - I took great exception to that

@Dan We sort of have to 'do' Dell and the other big providers of kit

no-one else can cope

@Dan complain back directly. Always gets results :-)

I may have mentioned I'm generally argumentative if suppliers send sales folks

@RoryAlsop I don't really get to build relationships with vendors as I'm too all over the place, but this customer is a Cisco shop so don't really have the contacts yet

@Dan not ideal

ho hum - I did what I needed to do

@JennyD I programmed in PHP for a while...

@MichelZ May you die a painful death.

Hey. I've written PHP too!

php sides next to java and adobe for me.. avoid as much as possible.

oh, are we bashing program languages again?

@MichelZ I've refused every time somebody's tried to push me into doing that

Newsflash: everything sucks!

PHP is retarded whereas Perl is Voodoo

PHP is easy...easy to write, and easy to screw up. It's so easy, in fact, that a developer can write PHP scripts (usually wrongly).

morning

@cole mornin'

@cole hey

How goes it?

@cole watching doctor who, pretty good :p

I've not seen the latest ep yet

@JennyD you should...

I'm planning to.

I would not visit any social networks till you do, spoilers EVERYWHERE

I'm reasonably good at ignoring them.

Guys can anyone help me with upgrading php-mysql client on centos 6?

Set phasers to "kill".

?

Protip: don't try adjusting caching and headers in IIS in production. It usually ends badly.

No one here knows anything about Centos 6?

@MarcRasmussen nuke it from orbit, it's the only way to be sure

@MarcRasmussen We know quite a lot about CentOS 6.

@MarcRasmussen Centos - sure. PHP? Dear $DEITY keep it away from me...

@MichaelHampton Are you able to help me?

@MarcRasmussen Yes, I am able to help you. I am, however, not willing to help you.

@MichaelHampton how come?

@MarcRasmussen If you look, at the top right corner, there's a text that starts with The Comms Room. Could you maybe tell me what the first sentence in the text says?

'An unspecified error happened on the page, please try again or contact technical support.' ...I love when that happens

@MarcRasmussen Because this is not a support channel.

And you aren't paying me enough.

@MichaelHampton i see well thank you for your help anyway have a nice day.

@MarcRasmussen Aww

what was the problem?

@ewwhite Don't do it! You'll regret it!

k

@ewwhite cluelessness

I'll stay away.

@ewwhite Just trying to fix php-mysql client since it runs on 5.1 where my server runs on 5.5

but its fair enough il gladly follow the rules of the room

Just thought that the idea of SO or SF was to Q/A

@MarcRasmussen It is but we value people trying to help themselves and that generally means reading the documentation and searching google/SF first

@MarcRasmussen The idea of the QA site is. This is not the QA section, this is the chat section.

@Iain ive been trying for hours now..

@JennyD That may be. but seeing as no one is chatting here anyway i thought i might try my luck.. gives people something to chat about don't you think?

@MarcRasmussen then you should speak to your manager abouts ome training - this shouldn't take hours

@MarcRasmussen Oh, my eyes gloss-over when I see anything about "php" or "mysql"

@MarcRasmussen true, we can chat quite a lot about how we hate PHP and don't do live support here...

@Iain Maybe not but im the only one at the office at this point.

shrugs

@JennyD True. what a fantastic conversation that could be..

@MarcRasmussen get yourself some training then

@Iain kinda what i am "sort of" looking for right now.

@MarcRasmussen It would certainly be more entertaining than actually working with PHP.

@JennyD Clearly.

and probably contribute more to the overall happiness of the planet

basic linux/CentOS sysadmin stuff I guess

@JennyD and stop the crisis in the middle east.

SF gets maybe one question a week along those lines. So I'm sure with a bit of searching you can find something appropriate.

@MarcRasmussen If everyone busy fighting there would just sit down and complain about PHP on chat sites instead, it would certainly be more peaceful.

I think we have the solution here...

and if we harness the energy from all those keypresses we'll have solved peak oil, too!

@MichaelHampton ive asked a question, and have been trying to search for answers yet none helped me.

@JennyD Lets send a consultent to the middle east to suggest the idea. I think you would be the perfect candidate. So strap on a bullet proofwest and get going :)

Was that your question?

@MichaelHampton yes

@MarcRasmussen That message from phpMyAdmin is silly and you can safely ignore it. Though one may also question your sanity for installing phpMyAdmin to begin with...

Why would you even use PHPMyAdmin instead of MySQL Workbench

@LucasKauffman To ensure that your web server gets compromised?

Didnt know workbench could be installed on Centos

@MarcRasmussen if it's got a desktop environment, yes

@MarcRasmussen so that's a production system ?

oh that did make my day.

@LucasKauffman it does not have a desktop environment

I still need to reset and migrate my mail and webserver

I am currently "enjoying" converting a metric shitload of UserAlias and HostAlias from a huge sudoers file into LDAP-netgroups. This would be very easy to script, it's just that I need to also check whether the groups are in fact correct, and that involves communicating with humans.

I hate that.

%humans

@Iain you really love that right now do you? the video was nice and we should propagate that.

yes, it amused me
