Overview On July 20, 2016 we experienced a 34 minute outage starting at 14:44 UTC. It took 10 minutes to identify the cause, 14 minutes to write the code to fix it, and 10 minutes to roll out the fix to a point where Stack Overflow became available again. The direct cause was a malformed post that caused one of our regular expressions to consume high CPU on our web servers. The post was in

Q: vc_redist.x86.exe Setup Failed: 0x80240017 Unspecified error

Nicolas RaoulAn installer told me I need to first install Visual C++ Redistributable Packages for Visual Studio 2013 and gave the link https://www.microsoft.com/en-US/download/details.aspx?id=40784 Unfortunately that link, after a few selection steps, does not download anything, so I unfortunately had to get...

 
nice duplicate find
 
@JourneymanGeek My Q6600 based machine runs Windows 10 perfectly... I think.
I have booted it in a while.
Perhaps it's still on 7. D:
 
cat
It's a quad core, course it will
 
Dammit, now I have to set it up when I get home to see what is has on it.
 
cat
Even my 10 year old laptop would run Windows 10
Heck it ran Vista and Windows 7 just fine, and just about nothing's more resource intensive than Vista
Vista is like, the OS equivalent of "Can it run Crysis?"
 
12:12 AM
We need a new "Can it run Crysis?" saying... I'd propose Star Citizen, but that game is turning into Duke Nukem: Forever.
 
cat
@MichaelFrank As in, taking forever?
@MichaelFrank We don't really need a new can it run Crysis saying though
Even the newest and fastest GPU available right now still can't run Crysis 3 at max settings on 4K
We're still like 2-3 generations away from that
 
@cat Oh, okay. I've not cared about Crysis for a long time.
 
@MichaelFrank "How many users can it run Virtual Desktop Infrastructure for?"
Though that's probably better for big servers
 
I have a Thinkpad T61P it runs Windows 10 like a champ
that thing is from 2004, lol
Thinking about doing a $65 upgrade to an SSD
it would have 4x as much storage as it has now ;-)
( 60GB HDD )
Its my "objects hit the fan" device.

@BenN Over 9000
 
12:39 AM
@JourneymanGeek that's really cool; I didn't know that :)
 
12:51 AM
@allquixotic that's the famed Sim Lim Square. I have never walked into a greater hive of scum and villany ;p
@MichaelFrank c2d, one gig of ram
@allquixotic there's specific stores that sell 'pulled' ram cheap in SLS, though they're a bit hard to find since there's a few hundred stores there.
 
Devious web trick: while a person is scrolling down, create a text box with an email-like ID, hope they're using the down arrow key to scroll down, hook up some JS to send the contents of the text box to the server whenever it changes, and collect all the person's e-mail addresses when they accidentally spin through the autocomplete
That may have just been pulled on me
sc start Tinfoil
 
@Ramhound Wow.
 
hi
 
1:07 AM
@Ramhound 0_0
I'm sure those are newer
and IMO, the SSD is an excellent idea
 
I dont trust SSDs
 
all storage eventually dies
2
 
yes its just my SSD died very soon
 
@Ramhound I threw some no name, dramless 120gb ssds into it. The change is pretty dramatic
@mrenigma excellent, you should RMA it, and restore from backups
 
what is RMA
 
1:11 AM
I run all sorts of dodgy storage and I'm oddly fine tho
@mrenigma get it replaced under warranty
 
my brother bought it and he cant find the recipt
 
RMA = return material authorisation - you let the manufacturer know its spoilt, they tell you how or where to send it back, they send you a new one
 
its fine though
 
You may not need a recipt.
 
my data is fine at least
 
1:29 AM
@mrenigma Return merchandise authorization—basically a confirmation of your intent to return an item to the vendor or manufacturer.
 
ill give it a try
 
Jan 16 '15 at 23:34, by Journeyman Geek
Also, all storage dies.
I'm not one to skimp on things like this. If you have the money, I'd just recommend the SSD 850 EVO, in either 120 GB or 250 GB.
 
I have that exact drive
it failed after using it a few times for around 8 or 9 months
 
You should definitely RMA it.
 
Well then, you probably got a fluke. Samsung will happily exchange it for you.
 
1:32 AM
I have the 850 PRO.
 
I'm personally running a 512 GB SSD 850 PRO and have had no issues whatsoever.
 
@cat It's for an exhibition. School kids will be coming to see IoT concept demonstrations. I've never worked on a Pi before and I'm not supposed to mod anything or even take the unit home. It's so hard figuring out what to do.
 
cat
Ow
 
10 hours ago, by Nick
@cat I'm in a worse situation. I have one day to make an insanely interesting project with a RasPi2 demonstrating IoT. Most of the simple stuff like doorbells and thermostats are already taken.
> Insanely interesting project
Wow. Looks like any old IoT project will get rejected.
You're being asked to hit a really high standard here.
 
@bwDraco Not technically. It's just that everybody took the easy ones like remotely blinking lights and stuff.
 
1:36 AM
@Nick CCTV is probably too simple...
 
I'm planning on serving Wikipedia offline using Gozim.
 
(CCTV is not an uncommon application at all for RPi, considering the GPU built into the SoC was built for video streaming...)
 
If it has a camera, you could do something with color histograms, which are kinda neat
 
@bwDraco It's been taken. My first project was a doorbell (basically, a button you press to start voice or video chat)
@BenN I have a usb webcam. As I said, not much to work with.
 
1:39 AM
@MichaelFrank XD haha!
 
Although they didn't seem too fazed by it...
 
They don't call it VideoCore for no reason.
It was originally designed for use in STBs.
The RPi3 features an overclocked but otherwise identical version of the VideoCore IV GPU.
 
Ugh... I have like 40 laptops to wipe... and the only tool I have is HP Disc Sanitizer...
 
The CPU block, on the other hand, has changed dramatically over the years. It was once ARM1176JZF-S; it's now ARM Cortex-A53 MPCore.
 
> Single HP Disk Sanitizer cycle
First pass ‘00000000’ (all zeros)
Second pass ‘11111111’ (all ones)
Third pass random write ‘1 or 0’ & verify
Fourth pass ‘00000000’ (all zeros)
This could take a while.
 
1:46 AM
@bwDraco I have an RPi2 and sure, I can make an STB out of it but that doesn't demonstrate any real IoT concept. Does it? Unless I'm like downloading and serving a youtube playlist. Mhh, sounds like an ok idea.
 
@Nick Attach a microphone and make a voice activated jukebox?
 
If it has voice synthesis too, you could make a little voice-activated reminder thing
 
Raspberry Pi has been using custom Broadcom SoCs since the RPi2. Yours has an ARM Cortex-A7 MPCore processor block.
 
That would actually be useful, I want to make one of those now!
 
@MichaelFrank Ooh, that's nice and sounds not too complicated to set up quickly.
@bwDraco Yeah, that's the first thing they told me during the intro session. It's the same processor on my phone.
 
1:51 AM
4C Cortex-A7 @ 900 MHz.
 
Bob
@JourneymanGeek I still think you could've gotten branded SSDs for the same price :P
 
@BenN Just checked into this. Someone's already doing image processing. So, I can't play with that idea much.
@bwDraco I'm Oc'ing it at 1000 MHz
 
@Nick Most will have no trouble with this; it's considered safe.
 
Bob
@Nick If you have an infrared diode, you can make a remote-remote-control :P
(TV remote over IP?)
 
@Bob I'll probably tell my friend who's doing the remote blinking lights to make it his second project.
 
Bob
1:56 AM
@Nick Could also do it the other way around. Make an IR receiver! :P
 
@Bob Well, that doesn't sound hard. maybe i should combine that with the jukebox.
 
Bob
IR-sensitive LDR + maybe IR pass filter
Or IR phototransistor instead of the LDR
Or a ready-made module :P
 
If you have a DSLR, you could make a timelapse controller.
 
cat
Make love, not war timelapse controllers
 
What's wrong with timelapse? :o

@MichaelFrank Not every camera has a cable release terminal. While mine (Pentax K-3 II) does, most less expensive DSLRs are limited to an IR remote release.
 
@bwDraco Why not USB?
 
@MichaelFrank Not every camera can tether.
Even so, it's usually a proprietary protocol.
Many newer cameras allow wireless tethering (my DSLR does with a special memory card; my Nikon compact has it built in) but you're basically going to be automating the operation of an embedded web application with PhantomJS at this point...
You'd also need a Wi-Fi dongle and a way to manage connections both to the camera and to the outside world.

@pjc50 Once I was working with a US student and a Canadian postdoc. The postdoc kept saying "zed" instead of "z", and eventually the student asked "What's a zed?" I told her it was a backwards z, but since we didn't have those on our standard keyboards, we would just type "z" — Scott Seidman 10 hours ago
 
@Bob "zed" is the way one says Z in Commonwealth English (including en-GB and en-AU).
In fact, "zee" is considered incorrect in en-GB.
It's actually en-CA, but that's still Commonwealth English.
 
Bob
3:24 AM
@bwDraco Somehow, I think I might have been aware of that, being Australian and all, y'know...
 
cat
And if you stare at the R for long, it sort of looks like someone got a stretchy omega and pinched its center to join the two legs, and moved it up and to the left a bit. — Kroltan 15 hours ago
We call it Z in the UK. Only people who use "zed" are those odd Americans who like to bastardize the English language then call it their own.
 
3:50 AM
@Bob No need to understate it, just say it upfront.
There's no need to be polite here.
Apologies if I had insulted you.
...okay. Why am I encouraging bad behavior?
"No need to be polite"? What on earth did I just write?
 
Bob
@bwDraco Sorry, was just in a bit of a sarcastic mood :P
 
This is what I mean when I say my lack of a sense of humor is serious enough to potentially get me in trouble.
It's getting late here and I wasn't exactly in a good mood when I stepped back in to respond. Sorry. This was my fault.
 
After reading all this I can't remember how I pronounce Z. D:
DAMN YOU ALL!
 
Hm. My PC can't reach anything over ipv4
@MichaelFrank zed. You ain't merican
 
4:07 AM
hey check this out it is a Replicator, converts mass ammounts of power suntowater.com/technology-atmospheric-water-generator into water. Only uses about as much power as a houshold uses every day, and outputs 1/3 of the water a houshold would use. No less interesting, it is going to be a dry air summer :-)
It is a good thing they invented this, because the 3/4 full resivors (during drought) one of thier problems is having enough water to generate power. uhh yea that my friends is a Loop. another insanity loop.
now i dont know what type of "salt" they are referring to, but the web (even) recognises that salt is a very poor dessicant. and Salt being added to water (oceans and waterways), is one of the reasons why water is a problem. and watering your lawn with a bit of leftover salt, or it getting into the land by sheer accident, kills everything pretty good.
 
there we are
@Bob at that point. Maaaaybe
there's been a recent price drop so yeah, quite certainly
but meh, the risk is half the fun

What're the chances it'll actually arrive tomorrow? :P
It's about a 12hr flight to Sydney
so it should arrive here around midnight.
Then... I guess I should hope they deliver straight here rather than via a depot?
 
bob is hoping the cargo plane is shot down over his house :-)
 
Bob

oh. it hasn't actually left HK :(
 
whoot
I can read local rail cards from my phone
 
5:33 AM
i cant believe they jammed 128Gig into a micro sd (long ago) , I thought the 64 was going to about top that for some time. Now if a 64 works, android 4.1 isnt it likely that a 128 would also work? (even if it does not say so in the manuel because that didnt even exist then)
In fact I think only the 32g was in the manuel, but i guessed/hoped,and purchaced locally and the 64g worked great. filled it to the brim to test as soon as i had it.
 
5:45 AM
So woke up for work this morning
wife is already awake and being having strong pains the last hour
@Psycogeek I think 64Gb was the max in the spe
yey finally

Q: How to remove conditions from WHERE clause if parameters are NULL

user3339988I'm passing 2 parameters to a PL/pgSQL function. Here's the query: SELECT * FROM table WHERE col1 = param1 AND col2 = param2 Both parameters can be NULL, in which case the respective expression should be removed from the WHERE clause. How can I do that? With IF conditions?

Very tempted to simply edit the sql query via code
Not sure if that's stupid
But in my head it's better than 4 sql queries
what's the standard way this is done ?
goes back to work
screw it, I'll form sql queries using code. I'm doing what an ORM does now .-.

google url shortened photos should not be posted*
i learned something today
messing arround with google url and adding a ?.jpeg and uploading it to stackexchange produces intresting results
ranging from loading the photos renders as clicks and total laggg
 
you mean uploading it to imgur
 
stack exchange doesn't host images itself
 
@CodeX did this and it redirected to a cake image
whats worse,
the google url shortner has a built-in locator

ugh! yet another super unhelpful comment from RH.
 
You should tell him here? ;p
 
8:11 AM
i told him on the question
which probably means he is going to go super grumpy
 
ah, ok
 
so i apologise in advance for future drama
i try to limit my interaction with the user as everything i say tends to make him fly off the handle
 
rh has a bit of a history with comments
Its a bit frustrating cause I don't quite see why hald the time
 
@Burgi Yeah, he has a habit of saying "there is an answer on this site" and then doesn't bother with a linky or flagging as dupe. That habit really annoys me. If you know the answer have the decency to tell the OP where it is instead of teasing them.
 
agreed

@Burgi whose backbone? There are multiple providers with multiple backbones ya know
 
@cat BT

BT's backbone is MPLS anyway
 
hm. This is going to be annoying. I need to rebuild a large chunk of my rss feeds cause one of the providers I use for em went down.
 
Hehe. I can't load bt.com :)
 
cat
9:14 AM
Eh VM have a good presence in Manchester. In fact a good many of their backbone links terminate therr
They also provide pretty decently priced symmetrical gigabit business lines.
Good enough that you don't have to pay crappy hosting providers anymore :-P
 
A live outage map on DownDetector shows reports coming in from London, Birmingham, Manchester, Sheffield, Milton Keynes, Leeds, Nottingham, Bristol, Liverpool, and Leicester. There are also problems on Plusnet and Sky. Plusnet's Twitter handle posted the same tweet as BT.
"We're sorry some BT and Plusnet customers are having problems connecting to some internet services this morning. One of our internet connection partners in the docklands has suffered a substantial power failure. This is affecting BT and other providers. We are redirecting traffic to reduce the impact on customers. Engineers are on site and are fixing the problem."

Q: Warlords of Documentation: A Proposed Expansion of Stack Overflow

Kevin MontroseIt’s been 7 years and 10,000,000+ Questions since Stack Overflow was launched. The amount of good that has been done for the field - all the developers helped, all the person-hours saved, all the beginners who grew into professionals - is hard to overstate. I cannot express how proud I am of what...

@Psycogeek Yes. If it supports SDXC at all (required for >32GB cards) it should support anything up to 2TB
And there's 256GB cards now btw, not just 128
 
Bob
@Boris_yo Windows 10 install should be fine. Recovery partition might not work anymore, especially after move to SSD.
You can just use Win10 on a flash drive for recovery.
 
cat
Good! Recovery partitions suck
 
yes, blow them away and recover the 10/20/30gb space
 
cat
They need to stop existing or adopt the schnApple technique
> BT broadband users have been unable to access some websites again, following problems with the service yesterday.
The firm said the fault stemmed from a power failure at another "connection partner" in London's Docklands.
Telehouse North confirmed that its network had been affected by a tripped circuit breaker.

"If this level of disruption can be caused by a power problem on one floor of one building housing part of the infrastructure in the UK, you really have to ask how resilient is this piece of critical national infrastructure," he said.
@Burgi yeah but now we know the cause
 
was it a lightning strike?
 
@cat cool, i wonder if there are fast good ones too.
hmm the samsung 256 is ~$200 , and they have a warning that it is a choking hazard. yea at that price i am choking :-)
 
cat
10:31 AM
@Psycogeek Mine's a 128G and it's fast (150MB/sec read, 50MB/sec write). Though it's not the fastest, and has some compatibility issues
 
Bob
...
mine's 64 GB 80 read 20 write lol
 
cat
My phone's limited to 50MB/sec anyway -_-
 
Bob
but really that's good enough for a bit of extra photo & music & maps storage on my phone
 
cat
Mine also reaches 108'c when writing at full speed
In retrospect, it wasn't a particularly... necessary purchase, but I wanted to try more speed.
I'd love for mine to be good enough for a bit of extra photo & music & maps storage on my phone but the constant hanging and unreliability makes me loathe to trust it...
 
I was using the sandisk extreeme, which is faster than the phone will ever be, but could have longer lasting use in other things. When put in a tiny reader, and run on the pc to fill it, it probably goes over spec temps. The finger test causes skin steaming :-)
 
cat
10:35 AM
... Once it died on me just while I was getting on a plane and needed both the maps and the music.
@Psycogeek Yeah the finger steaming is what led me to measure it with a thermal camera :-D
 
Bob
@cat my Transcend worked fine until it didn't :P
now my Samsung Evo Plus works fine
it'll fail one day
 
cat
@Bob lol
 
Bob
but no ongoing reliability issues
finger... steaming?
 
at any rate, the tech for a micro is simply amaZing! when a thumbnail sized chip, that can be transported by a homing parakeet can store a set of movies that a few years ago would take a 1/4 of a room to store.
@Bob fingers steam at 210*f :-) or 100*C
 
Bob
shudder
some things should not exist
 
10:52 AM
@JourneymanGeek Thanks!
 
@cat @tombull89 They suck because they stuff bloatware or there are other reasons?
I think that in order to cut down to 120GB SSD size I will backup recovery partition to external HDD and delete it before shrinking to 120GB size.

You said recovery partition will not work, especially after moving to SSD. Are they compatible with OEM only part i.e. HDD that came originally with laptop?
@Psycogeek Ever held in your hands Sony Walkman NWZ MP3 Sports Player?
 
Bob
@Boris_yo I said it might not work, because your cloning tool will be shrinking/moving partitions and maybe reassigning IDs.
I've not actually tried it.
 
I have mine but it connects and disconnects intermittently. Thought battey getting dead but after wiggling it I found certain spot that prevented disconnections. Anyway I think the problem is how contacts are leveled:
