@voretaq7 so I assume you've heard SE's SRE plans for next week? All the hardware upgrades.

Luckily we're also doing a product launch next week.

voretaq7

02:29

@BretCopeland You mean breaking shit? :-)

("Hardware Upgrade" is sysadmin speak for "I'mma break ALL THE THINGS")

Bret Copeland

I hope so

I asked if we were going to be running out of Oregon while they were upgrading the web tier, but nope.

Seems like it would have been a good opportunity to test failover to Oregon, but I guess no one cares about that DC.

voretaq7

eh, you guys have decent redundancy, you can split the load balancer, upgrade half of NY, dump the load onto the upgraded boxes & then do the rest.

Bret Copeland

yeah, I think they're doing 3 servers at a time, or something like that.

voretaq7

I have SO MUCH SOFTWARE to deploy next month.... seriously thinking about quitting :P

(I hate major deployments)

Bret Copeland

yep, going to be 2/4/6, 1/3/5, 8/10, and 9/11

@BretCopeland Windows Environment :-P

Bret Copeland

eh, it's both. There's a surprising amount of Linux in our DC.

voretaq7

y'all need to rewrite everything in Ruby and I'll help deploy a nice BSD/Passenger backend :)

Bret Copeland

And we even have one OSX server for iOS builds.

voretaq7

@BretCopeland It actually is surprising how much Linux you guys have

(mostly that it's Linux - I would have thought the Linux community's propensity for instability and chasing the newest shiny would have driven you guys away by now!)

Bret Copeland

Basically, web tier and SQL is Windows. Most other things are Linux.

@voretaq7 no thank you. Though we use puppet for all of the SRE automation, which is ruby.

voretaq7

02:37

Bleh. SQL server. Tastes like Sybase.

Bret Copeland

@voretaq7 gee, I wonder why

voretaq7

@BretCopeland Nope nope totally not sybase nope not at all nope nope nope.... ok maybe a tiny bit.

but we bastardized it and superglued a GUI to its sensitive bits!

Q: Is it possible to implement an Acronym/Jargon buster?

There are several questions on this meta regarding acronyms in tags and questions, and it's undoubtedly a tricky issue when it comes to Aviation... there are multitudes of acronyms involved in both direct Aviation (ATC, VOR, VMC, ILS) and the areas surrounding it eg bookings (GDS, PNR, TTL, ADM)....

Forgive me, father, for I abused my editor privs today.

i had downvoted an answer, but it was pointed out to me that my objection was wrong, and I couldn't change the down to an up. So i edited one word, changed the vote, then rolled back the edit.

@SentryRaven seems like they all want to know about unusual attitudes in transport aircraft

falstro

15:39

@rbp hah! Clever :)

voretaq7

17:56

@rbp seems legit :)

fooot

How about the other way around? Switching to a downvote? More abusive?

voretaq7

@fooot eh... slightly less legit

Farhan

Downvoting penalty is removed, isn't it?

I think it was -1 or -2.

Bret Copeland

@Farhan downvoting a question costs you nothing. Downvoting an answer is -1.

It's -2 to the author in both cases, I believe.

Farhan

@BretCopeland Yes, that's correct.

Farhan

18:17

I never downvote others because stupidity is in abundance. But when others downvote my posts, I just ~~wish that somehow karma and bad luck apprehend them, and have imaginations of a cattle prod and their melon-shaped empty orbs~~ ignore.

fooot

@Farhan If it's bad, and been made clear to the author why, I sometimes downvote. Downvotes with no explanation are not helpful.

voretaq7

I downvote anything that's bad enough to make me frown/wince/WTF at it

(or anything that's just a really awful answer, like "Hey, go click this link and read Wikipedia")

Bret Copeland

18:39

I only downvote out of personal spite. That seems to work for me.

Bret Copeland

This is absolutely brilliant interface design work: ssh -t means something different from ssh -t -t stackoverflow.com/questions/7114990/…

voretaq7

@BretCopeland Multiple -t options force tty allocation, even if ssh has no local tty

in case you want to use a graphical menu via an Expect script or something

(Look there's only 26 letters and 2 cases. When you have as many options as ssh you need to get creative! :P)

See Also: ls [-ABCFGHILPRSTUWZabcdfghiklmnopqrstuwxy1,] [-D format] [file ...]

Bret Copeland

Maybe something like, I don't know, --force-tty would be a little more readable and obvious.

falstro

19:33

@BretCopeland it's obviously the same as -t, just more so! ;)

Bret Copeland

ssh -t -srsly

casey

 623     case 't':
 624       if (options.request_tty == REQUEST_TTY_YES)
 625         options.request_tty = REQUEST_TTY_FORCE;
 626       else
 627         options.request_tty = REQUEST_TTY_YES;
 628       break;

id like to see the logic in the y case to turn it on only if it has seen t,r,l once and s twice :)

voretaq7

@BretCopeland You GNUists and your double-dash fuckery! :P

Bret Copeland

At least it's not the windows /Argument-Name

falstro

19:54

@casey so -t -t -t == -t ?

casey

yes, it appears so

voretaq7

@casey Ayup. Never let it be said Theo's monkeys write perfect code.

@voretaq7 should I submit this patch? ^^^

@voretaq7 there are certainly plenty of examples of those monkeys terrible code. Lets implement our own malloc!

voretaq7

@casey Those weren't Theo's monkeys.

Theo's monkeys did this

casey

@voretaq7 true but I bet they are good friends with them

Bret Copeland

20:46

@voretaq7 oh come on, what's wrong with OpenSSL?

voretaq7

@BretCopeland Nothing. :-)

Bret Copeland

That's pretty amazing.

See, I would have never thought to do that. They think outside the box.

voretaq7

21:01

I like being inside the box. Inside the box is a safe place. Outside the box is scary, and inhabited by predators!

Farhan

voretaq7

@Farhan See? Predator!

Bret Copeland

We have a pointy haired boss bot in our internal chat rooms who pops up when David (VP of Engineering) says certain things.

It posts this image

voretaq7

@BretCopeland PHB is Leader. Wally is Idol.

Bret Copeland

btw, @voretaq7 did you get the Operation Raincheck email last night. I saw it 38 mintues after it went out and it was already full.

voretaq7

21:13

@BretCopeland ayup. I missed it too

Bret Copeland

what's great about the PHB triggers is that in code, they're just hashes, so you don't really know what the triggers are unless you brute force it.

And it's randomized to only trigger 10% of the time.

falstro

Bots are fun

Bret Copeland

@voretaq7 you'd think they would notice the interest and, perhaps, just maybe, either add more events, or a bigger venue.

Or at least add more -t flags.

voretaq7

@BretCopeland 50-60 is about the right size for those things - I do wish they'd do them more frequently though

I finally had a chance to meet Paul (the new FAAST guy in Farmingdale) this week - perhaps I'll harass him about this…

Bret Copeland

I need to find a way to get my phone to FREAK THE FUCK OUT when it receives an Operation Raincheck email.

falstro

21:17

@BretCopeland heh, I should totally build that into the bot at work. It's IRC though, so no pictures, but markov chains can be fun too :)

voretaq7

@BretCopeland . . . hmmmmm

Bret Copeland

The bot actually responds to the person David was responding to initially, which makes it even better.

voretaq7

procmail filter that scans subject lines for /RAINCHECK/ & From: header for /faa/ - automatically clicks through to any links in the email

"AIEEEEEE REGISTER ME REGISTER ME NOW TAKE MY FIRSTBORN CHILD!"

Bret Copeland

Oh that'd be even better. Like a secretary - just notifies me that the event has been added to my calendar.

casey

21:34

@voretaq7 doesn't sound exploitable at all :)

voretaq7

@casey I don't recall if the SPANS emails need you to enter your password

I think there's a token in the URLs

falstro

unf. sleep. tgif tomorrow, last 5:30 wakeup call of the week.

voretaq7

@falstro Bleh.

falstro

Also, awesome: flyingmag.com/aircraft/turboprops/…

Bret Copeland

I assume the production version won't require a start cart.

voretaq7

21:49

@BretCopeland . . . why not?

"I'd hate to be a bother, but can you bring a huffer over to my DA-50? NO I'M NOT PLAYING A JOKE ON YOU!"

Bret Copeland

I don't know. The Concord and SR-71 required start carts, so why shouldn't a 175kt-cruise 4-seat single?

If you want to play in the big leagues, you have to act like you're in the big leagues.

voretaq7

@BretCopeland …begin by convincing them you burn Jet-A :)

casey

@voretaq7 I was thinking more of embedding malicious links into emails with that subject and a spoofed From: header

not hijacking your FAAST account

voretaq7

@casey No skin off my nose - the script would just do an HTTP GET and discard the results...

it's not like it's actually going into a browser :)

casey

true, I trust you'd do it right, but I can think of plenty that would find a way to do it terribly wrong (chrome extension!)

rbp

22:10

regarding the DA-50, the middle altitudes are the best place to fly, except for weather and pressurization

least traffic, fewest obstacles

climb to 17,000 press DIRECT TO anywhere in the USA

i downvote for lots of reasons, including personal spite, answers that make gag, any other answer on a question that I also have an answer

voretaq7

Boredom. Hunger. Wanting to be the world's fattest man.

Bret Copeland

22:28

@voretaq7 was this a status update?

voretaq7

@BretCopeland Sure, why not :)

(I'm reimaging a laptop that was riddled with malware - that's my status at the moment. Fuck the world, I wanna blow it all up)
