Sustained 3A @ 5V is hard to do without expensive premium cabling.

Even worse than this because we're talking about 4A at no more than 4.4V.

Mokubai

@bwDraco 3A is easy. The problem is 3A over tiny wires people want in their nice thin cables.

I've got a metric shedload of cable that'll manage well beyond 3A, but it'll probably be rubbish for USB data.

people want their 30AWG "can't carry electrons without help" tiny stranded cables to be able to transfer 50A to their overpowered phones.

cat

I'd rather my phone just didn't need so much charging

Mokubai

@cat ebay.co.uk/itm/like/…

bwDraco

> "can't carry electrons without help"

rotfl

cat

@Mokubai I have one of those, battery lasts about 3 minutes

Guess that's what you get with a 15-year-old NiMH cell

Mokubai

19:13

@cat Yeah, you probably need a new one

cat

I'm pretty sure they don't make original ones anymore

Mokubai

At that age I'd be more concerned about it leaking noxious chemicals

cat

Oh it's leaked a few

Crusty grey/green fuzz creeping out of the sides

Mokubai

Didn't I see they'd re-released one of those old phones a week or two ago

@cat That probably doesn't help keep the electrons in.

cat

Heh

At this point the battery's really only useful as a capacitor for them old chargers

Mokubai

19:18

@cat Well yeah, but the big feature that distinguishes a battery from a capacitor is the ability to store more than a few micro-farads of charge...

cat

Well... it's kinda lost that now

Then again I'd be surprised if a 17 year old capacitor fared much better

Mokubai

@cat We've got some nice chunky bench power supplies with big caps in them at work, they're probably around that sort of age and still going strong.

They built PSUs to last back then. Then again they also built the heatsinks out of big heavy chunks of iron so.....

cat

I have a sneaking feeling your bench supply was built to a better standard than a consumer phone

That said, it is a Nokia, so you never know4

Mokubai

Ha. Shows what you know about bench power supplies and what they thought of "standards" back then.

cat

I knew nothing of bench supplies or standards back then, I was like, 12

Mokubai

19:22

-.-

Kids these days.

cat

11 actually

I was just lucky to be growing up in an era where phones could be dropped while boys were being boys

Using your phone as a football to hear funny doppler effects while it was ringing... heh

Is that an IIS error page?

Yes it is

cat

Lol, server error trying to open a page that has a screenshot of that error

Ben N

If it's IIS, the Server header will say Microsoft-IIS/ and a version

That Brazilian Guy

@cat Why is nginx trying to look like IIS?

cat

@ThatBrazilianGuy I don't think it's an nginx error actually, just found someone using nginx who had the same error

It seems to be being output by some backend framework

That Brazilian Guy

@BenN I have no PowerShell here, I'm on Linux

Ben N

19:33

Is the URL sensitive? If not, I can run the command

Alternatively, the Linux curl might have a way to get headers specifically

That Brazilian Guy

@cat The site is supposed to be running LimeSurvey (a php/mysql survey tool).

cat

It's being generated by the Yii framework as far as I can tell

That Brazilian Guy

It is also supposed to be running.

cat

@ThatBrazilianGuy Yeah, Limesurvey is a common application that outputs that error

Limesurvey uses Yii: manual.limesurvey.org/Yii

So it's not webserver specific, it's being output by the php backend of the web application

google.co.uk/…

That Brazilian Guy

@BenN Yeah, there's curl -I

Apache, why are you trying to look like IIS?

So it's not webserver specific, it's being output by the php backend of the web application

Ben N

IIS best S

The X-Powered-By header, if present, might tell you the framework or language

e.g. it's ASP.NET for one of my sites

cat

It's Yii framework and PHP

I did already point that out, twice

That Brazilian Guy

Yeah, it's limesurvey which uses php (according to @cat, Yii more specifically)

cat

And it's the "Chive" component (the DB backend) that's borked

That Brazilian Guy

It's taking dozens of seconds to timeout with that error

cat

19:39

That suggests an unresponsive database server behind the website

That Brazilian Guy

I wrongly assumed it was an IIS error page and WTF'ed because it's supposed to be a Linux server running PHP

cat

Lol

That Brazilian Guy

I even sent an IM to an server/infrastucture guy friend of mine and the words "IIS? Really"?

cat

Hah

That Brazilian Guy

That guy is also my current boss ;p

He hates windows servers with a passion

cat

19:43

It does look awfully similar, colour wise, to an IIS bork

They probably copied the colour codes -_-

bwDraco

> Server Error in '/oops' Application.

ROTFLOLOLOL

> '/oops'

@ThatBrazilianGuy Let's not forget that Stack Exchange uses IIS.

cat

Then again, "red" and "maroon" aren't exactly rare colours to run across

Ben N

Right, they run a mostly MS stack, though there are some Linux machines around

bwDraco

Microsoft is so verbose when something goes wrong.

At the same time, they use such utterly unintuitive error codes...

Ben N

I wish Windows 10 install errors were more verbose - the pop-up after an upgrade failure literally says "Something went wrong" with no error code at all

cat

19:49

Your face is a mostly MS stack!

@BenN At least you got a pop up

Mine just hung at a spinny circle for 6 hours

Literally nothing else on screen.

Ben N

It would be good if more error messages automatically resolved the 0xblahblah to an error code or message

bwDraco

> Something happened

cat

MS have almost done that with some things

Sneaky/lazy buggers in fact

That Brazilian Guy

@bwDraco Yes, although I'm heavily biased, I'm not a blind hater.

cat

Some "get help on this error" links are now just links to Bing search <error code>

Ben N

19:51

And all the results are those terrible sites that say the same thing for every code

That Brazilian Guy

I know there are big projects and infrastructures that use MS, IIS, etc

Ben N

They could at least link to the official listing of system error codes

bwDraco

Windows 10 does not ship with a help system.

cat

@BenN That would involve them bothering to write an official listing

Ben N

msdn.microsoft.com/en-us/library/windows/desktop/…

cat

19:52

Evidently this is happening because they're now too lazy to write official documentation

That Brazilian Guy

The context here is (1) I knew it was a PHP application, and (2) I knew the guy hates windows servers and is actively replacing them for Linux ones, and (3) our workplace vouches for FOSS adoption. Theoretically, at least.

cat

Oh it's a your workplace server?

Ben N

I set up an Ubuntu Server with LAMP for phpBB3 yesterday

It went OK considering that I had literally never used Ubuntu Server before

My experience with Linux software is that you always have to fiddle at least one text config file somewhere before the thing will actually work

That Brazilian Guy

@cat Yep. It is. And it's offline. But it's not like it's anything important, it's just a survey. Linked on an full-page, expanding iframe on every page of our main site.

cat

lol

That Brazilian Guy

20:01

aaaand It's back.

cat

I'm a cat, meaow, check meaowt

That Brazilian Guy

Oh, lord. Turns out I have SSH access to the server +_+'

I don't know why I still do, and it was technically ~~not my problem~~ out of my jurisdiction, and someone seems to have fixed it quite quickly, so... all's well now \o/

cybermonkey

20:24

Can anyone familiar with databases tell me how quick this import is for a DBMS?

That Brazilian Guy

@cybermonkey That's nearly unreadable. And there's no context. How many rows? What kind of data? What DBMS? Etc etc etc.

Not that I know much about DBMS and even if you provide this info, I myself can't help you

(although some other people here might, possibly)

Oh my LOL, this is golden:

Hello, everybody. This isn't particularly on topic here. But it's no more on topic anywhere on SE either. I was wondering if anyone knows how to write on a Wikipedia Talk page. Do I edit the source? If so, that seems weird. The particular talk page is en.wikipedia.org/wiki/User_talk:Notthebestusername

Ben N

20:40

If you want to start a new thread-like thing, click New section in the upper-right

Faheem Mitha

@BenN Oh. Is that the correct way to start a conversation?

Ben N

In my understanding, yes, that's how you start new topics on talk pages

Faheem Mitha

@BenN Ok, I'll give that a try. Thank you. I really just want to take the conversation to email, but he said I could contact him via the web page. WP usage doesn't seem entirely obvious.

Well, the backend stuff, anyway.

A: Does the President of the United States have the ability to deploy nuclear weapons at will?

Yes, because the Constitution says so. Under the United States Constitution, Article II, Section 1, the President is the "Commander in Chief" of the armed forces: The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, wh...

It can't get any simpler than this.

This is the logical result of any reasonable interpretation of the Constitution. Not much more evidence needs to be provided.

Faheem Mitha

I'm hoping Trump isn't as bad as he seems. And he seems pretty bad, so maybe that's not saying much. Sorry for the OT.

Mokubai

The question becomes "would anyone listen to the (obviously insane) president that ordered to fire all the nukes?"

Ben N

blog.dilbert.com/post/145309172876/…

Trump is pretty crazy, but I don't think he's as bad as some people say

Faheem Mitha

@BenN Well, bad is relative. Most "major" pols tend to be pretty awful.

A: What would be causing white streaking issue when printing?

This looks like a laser scanner problem. You'll need to get the printer serviced as this is not a user-serviceable part. If this problem was repeating vertically, the drum would probably be to blame. However, because the drum and transfer belt both rotate in the direction of paper movement, neit...

Weird.

The above answer has been pulled.

DavidPostill

@bwDraco pulled ???

bwDraco

Downvoted and I likely cannot meet the site's specific requirements.

Michael Frank

@DavidPostill I think he's talking about his nuke answer.

Not the laser printer one.

Ben N

Everything's normal for me - try a full reload?

DavidPostill

@BenN I did. The topbar flashes and disappears.

Ben N

Interesting. What's your browser?

DavidPostill

@BenN Firefox. If I uncheck "Fix topbar position" it works on sceptics.

@bwDraco oddly that is pretty much all the president can do :-) cause problems for everyone with the most pricey military and security system on the planet. and if they had maintained the proper "declaration of war" the little weasil(s) couldnt do that without representation by the prople, something that seems to have gotten lost. Between the blaming the president for everything congress is doing, and the presidential EGO of making believe they are dictators of the country.

the original ideas of the constitiuion are as badly really and perceptionally screwed up, just like everything every where else. comunism isnt comunist, facism was never really faciest, monarchies werent monarchies , and this constituional republic capitolism is anything but.

one could tend to believe if there was a common system, or uncommon seperation of systems fighting eachother, that the basis for all of them and any of them is just raw Stupidityism :-)

ready for this, the hitler faciest regime actually had better represenation of the people than the american republic fraud. Around 75% of the german country for much of the time (during that time) agreed with the actions of the dictator. Many times less than 50% of this more advanced civilisation actions in the republic (US) agreed with the actions of the government.

Android version history

The version history of the Android mobile operating system began with the release of the Android alpha in November 2007. The first commercial version, Android 1.0, was released in September 2008. Android is continually developed by Google and the Open Handset Alliance (OHA), and has seen a number of updates to its base operating system since the initial release. Versions 1.0 and 1.1 were not released under specific code names, but since April 2009's Android 1.5 "Cupcake", Android versions have had confectionery-themed code names. Each is in alphabetical order, with the most recent being Android...

Great—this means that Android updates aren't going to take anywhere near as long to complete.

bwDraco

This is especially significant because I run CyanogenMod nightlies. Let's hope Cyanogen is working on getting CM14 out ASAP.

The "Android is upgrading" screen drives me nuts.

Less time installing apps means less time waiting on "Android is upgrading" every time I update the system.

Michael Frank

23:18

@bwDraco You mean optimizing? That's going away completely with N AFAIK.

bwDraco

During this stage of an Android update, apps are basically getting reinstalled. For older versions of Android, this meant regenerating the Dalvik cache. Since version 5.0, this means compiling the Dalvik bytecode to native ART code.

Android 7.0 speeds this process up dramatically.

Is ATA Secure Erase reasonably secure?

Or does it entirely depend on how the manufacturer implements it?

oldmud0

I don't know why don't you ask it

It's sad looking at the pervasive circlejerk that is meta SE

how do you figure out whether or not somebody is question banned

Michael Frank

@oldmud0 They can't ask questions.

oldmud0

yeah but there's a difference between somebody can't and somebody just doesn't want to

you can't tell that difference

Michael Frank

You shouldn't need to tell that difference.

oldmud0

23:47

why not

one of them forces a person to not come back in 5 years, the other just discourages a person from coming back

the only place I would ever expect to be question banned is meta stack

Michael Frank

I've got no idea what you're talking about so I'm going to get lunch.

oldmud0

yeah well it's dinner time here

can I get negative stars

It is exceptionally difficult to get question-banned on any meta, including MSE

apparently circlejerk upvoting

Ben N

It might be worth considering that they earned what they have by some kind of effort or quality

effort? wtf you talking about

just ethos

Ben N

I upvote things I agree with, for instance

oldmud0

23:55

literally the answer "No." can garner a ridiculous amount of upvotes because people just look down and they see colorful dots and a big number

where is the effort in saying a simple "no"?

Ben N

Right, for devs, things are different

Psycogeek

@MichaelFrank if a person was to zero it first while they could visualise it, and verify that function, then to use the hardware based function, the most that could possibly leave at that point is broken blocks with partial datas, which would require a operating of the flash chips outside of the controller to get at. This is after combining data about zeroing, secure erasing and reallocation and reserve things that are always brought up about "fully" removing data from SSD.

absolutely no explanation

Ben N

What if someone with access to the machine using the drive saved the key? :)

oldmud0

how do you save the key if it's in the hw/fw level

Ben N

Oh, if that's the case, then that works

I was imagining a BitLocker-like deal

oldmud0

there is no sata "steal private key" command

there should be

Ben N

Fun fact: some brands of hard drives let you retrieve their ATA master password with the right command

Probably doesn't apply to that SSD encryption though

oldmud0
