@JourneymanGeek ...yea, that'd be about 800k-1.5 mil for a 2-bed apartment here.

Houses available but I shudder to think of the price.

Journeyman Geek

@Bob: ours is not too bad

That Brazilian Guy

I am insanely lucky for not having to pay rent

Journeyman Geek

XD

@ThatBrazilianGuy: I live with my parents ;p

A 202 sq. m house is approx 1.6 mil in that area O_O

2:05 PM

I live in a ---house--- 1 bedroom apartment *donated by relatives* :P
It was bought 25 years ago when housing was waaay more affordable, and then they donated it to me after my mom passed away and I was jobless.

Journeyman Geek

ahh

That Brazilian Guy

@Bob Remember the 2010 census says half of the country earns between 0 and twice mimimun wage, so houses in a poor area costing 225 times the mimimun wage is completely insane

Oh look I found an 80k one! ... ... it's a garage O_O

That Brazilian Guy

@Bob 80k USD? What is the average / median australian monthly salary?

@ThatBrazilianGuy I'm looking for comparison photos at the moment. Not for income comparisons - those were done above.

Speaking of - this is what a sub-100k house looks like. Actually outside of Sydney this time: realestate.com.au/property-house-nsw-fern+bay-118717455

@Bob It's made of metal plates? O_o

...at least it's got a backyard .___.

@Bob I could find the Singapore and Brazil comparision, but not Australia

Oh, that Salary Explorer link was actually with australian info

@ThatBrazilianGuy Probably because they had trouble finding similar prices :P

That Brazilian Guy

Is that at least nearly accurate? Because the Brazilian info there is... well...

@ThatBrazilianGuy The info there is incorrect.

See the ABS links later.

Unless they take the median average, not the mean.

Meanwhile, Telegram Web works on Firefox and does not require your phone to be on

2:37 PM

@ThatBrazilianGuy Chrome is the new IE.

3

It has a big enough market share now that people feel comfortable developing webapps that only work in it.

Becoming more common of late.

That Brazilian Guy

The web is a platform where sites and apps can run on any browser. As long as that browser is Chrome.

Journeyman Geek

lol

That Brazilian Guy

I just changed the user agent for Chrome Win 36 and WhatsApp web is working fine.

Seriously WTF!!!!

2:55 PM

> More browsers coming soon.

@ThatBrazilianGuy user agent sniffing is evil, especially if the purpose of said sniffing is to actively prohibit users with certain browsers from accessing the site.

a warning saying "we tested it with your browser and we doubt it'll work, but you can try anyway" is fine, as long as there's also a "don't show me this again" that sets a property in a cookie to remember that

@allquixotic Still implies they're doing something Chrome-specific.

That Brazilian Guy

@allquixotic Well, that's exactly what WhatsApp web seems to be doing.

@Bob but he changed his UA and it works -- I'm guessing he's not using Chrome

And it's looking more like that doesn't even affect the major functionality, considering it seems to work for @ThatBrazilianGuy.

probably they needed a feature that only Chrome version X or higher supports, and no other browser supported it at the time that they wrote the app

but FF has probably since caught up

That Brazilian Guy

2:57 PM

Maybe only Chrome 36+ has a built-in NSA logging & reporting tool. It's Mark Zuckerberg we're talking about here, remember.

@ThatBrazilianGuy what browser are you actually using atm?

and version

That Brazilian Guy

FF 35 on Fedora 20

2 mins ago, by allquixotic

but FF has probably since caught up

either the special thing they think they needed is so trivial that you can't even tell it's missing, or FF 35 supports it and they're too stupid to update their app to whitelist FF 35

Q: How many times can i format hard disk?

How many times can i format hard disk? i have seen this page:http://en.wikipedia.org/wiki/Hard_disk_drive, but i can't find any answer.

hard-drive external-hard-drive

As many times as your heart desires

seriously, people who implement UA sniffing for the purpose of blocking users from sites need to be summarily fired and have themselves added to a public "hall of shame" list for even coming up with the idea of doing that, let alone putting it into a shipped product

the proper way to do it is to either (A) don't sniff, and use web standards of the lowest common denominator of any platform that could sanely be out there still, and say "fuck you" to everyone who is using something older; or (B) gracefully degrade to a progressively simpler site based on how old/feature-deprived the user's browser is based on their UA

That Brazilian Guy

3:02 PM

@allquixotic Something like plaintextoffenders.com?

@allquixotic ...guess what we do? :P

@Bob ugh.

@allquixotic (to be fair - this is an internal app and my boss just cbf removing the no-IE restriction from it... and even IE11 doesn't support the stuff we routinely put in)

There's no plans to blacklist Spartan.

And do note that it's a blacklist, not a whitelist.

internal apps are one thing -- and yeah, it's pretty common for that shit to be extremely broken and only work on the "officially supported" browser of the company

mostly because they lack the money for a proper rewrite

@allquixotic Funny thing, that. I think I'm the only FF user here :P

Then again, the app recently moved to node-webkit (now nw.js) to use the NodeJS APIs to write to the local FS.

It's literally impossible to run in a normal browser now :P

3:05 PM

Ahh if your not using the broweser i chose , then do not visit my site, you are not worthy. and dont laugh when an update to the browser breaks the funtions again.

Journeyman Geek

lol

I use FF

@allquixotic Our product(s) support... everything.

Everything.

@Bob we have an internal app that requires a Java applet and an embedded encrypted PDF viewer; it's basically an HTML shell with a men that displays all the actual content (including fillable form fields) in embedded PDFs, and the whole thing is incredibly slow and broken

Except IE6. That's going too far.

I have no idea what the Java applet does; it has no visible UI elements

3:06 PM

I'm still supporting IE7 now FML

oh, wanna know the best part?

the entire site that the internal app is on, is served over a high-grade TLS connection (AES-128 or AES-256 with some crazy sophisticated cipher suites, not 90s-era tech) with a Class 2 EV cert

4 hours ago, by Bob

so WHY THE FUCK does it need encrypted PDFs with fillable forms

Q: User agent switcher for firefox

I have been using the User Agent Switcher addon for Firefox. It's good but I need one that works on a per-domain basis. This one promises that but won't work on Firefox 35 that I'm using.

firefox addons plugins extensions

3:08 PM

also, the site implements HSTS, PFS, and anti cross-frame-scripting techniques

Basically: this card's website requires Flash on the login screen despite the login apparently being implemented in plain HTML/JS.

again I wonder why the PDF is necessary

I do not see the Flash applet anywhere.

the worst part is that any small action within the "application" requires a full HTML page reload, and an accompanying Adobe PDF viewer (the default on 99% of our peoples' systems, since nobody uses pdf.js) plugin reload -_-

so: login, wait 45 seconds, click a button or link, wait 45 seconds, fill out a PDF form, click a button, wait 45 seconds....

@allquixotic to do what gain access to the whitehouse archives ?

3:11 PM

also, the techs' idea of good "cross-browser" support is this: oh, we support IE 8, IE 9, and IE 10!

@Psycogeek No. To view your employee pay stub.

(and other miscellaneous similar stuff)

So this is security by insanity ? sounds kinda cool cept the waiting part.

HKCR\service doesn't look like a context menu key to me. For example look at HKCR\Folder or HKCR\http. They both contain shell subkey by default, maybe also DefaultIcon, shellex or ShellNew. HKCR\service doesn't. I guess it's not what you think it is. — gronostaj 2 days ago

Q: Add context menu items to services (windows)

I am trying to a delete option to the right click menu of windows services, I know that you can do this with right click menus for files such as .cat / .bmp and I think you can here too, so I created the following: [HKEY_CLASSES_ROOT\Service\shell\Delete\Command] @="sc.exe delete "%1\"" However...

windows services context-menu regedit mmc

sorry

@snipe could you just use autoruns and delete them and turn them on and off at will there?

I could I suppose

assuming it works on windows 10

I have never assumed that these snap-in things would have a lot of configurations stuff in the registry. Although i would assume that they are created with some of the more simple programming (vrses say a kernal) and that they could be altered, hacked messed with like a lot of other things that MS didnt provide function for.

Linux and Mac support coming in the next few months, and they're merging a ton of commits from the community to push it along.

they already have 38 PRs processed lol

@allquixotic And there's a Linux build?! :D

@Bob build, but doesn't run apparently

> You can 'watch' the repo to see Linux and Mac support being added over the next few months.

3:59 PM

@allquixotic Still, progress!

@Bob I bet it's going to be way faster than Mono

Yep.

The last time I tried to time simple math, .NET was at least twice the speed of Mono.

MSFT has put a lot more R&D into CoreCLR than Miguel de Icaza has put into Mono

and for CoreCLR this means that we can now focus on making CoreCLR better (the immediate benefit is for Windows .NET devs, later on for Mac and Linux)

did I just hear the word mac

@allquixotic I just can't wait for the days of standalone C# programs.

Heck, just being able to incorporate the libs helps.

Most .NET 4.5 libs run just fine on the 4.0 CLR.

4:07 PM

@Bob .NET Native?

yea if you format with the bios it leaves treadmarks on the platters.

user image

@Psycogeek lol

If you want to you can use my picture to illustrate this fact

I don't use sarcasm in real answers on the site

@allquixotic Or just including a CLR with your program.

I remember reading something recently to that effect.

Making the CLR app-local is far easier than native compilation.

4:09 PM

@Bob .NET Native goes even further and makes programs start up faster and use less memory :D

And far more compatible with existing libraries.

imagine KSP running on .NET Native

@allquixotic Wouldn't .NET Native break reflection?

Or at the very least severely complicate it?

@Bob not necessarily; they keep a runtime JIT compiler under the hood that takes care of any mutations in the code

@allquixotic Then that compiler will necessarily be slow, big or both.

.NET Native seems more suited for some very specific performance-critical code.

4:11 PM

@Bob no bigger or slower than the existing JIT compiler; it just results in some parts of the native code being thrown out

App-local CLR is more widely applicable.

@Bob KSP :D

@allquixotic It would be bigger, though, if you're including a copy in every compiled program.

> The NuGet based delivery also turns the .NET Core platform into an app-local framework. The modular design of .NET Core ensures that each application only needs to deploy what it needs. We’re also working on enabling smart sharing if multiple applications use the same framework bits. However, the goal is to ensure that each application is logically having its own framework so that upgrading doesn’t interfere with other applications running on the same machine.

I wonder if that applies to the CLR too.

@Bob more disk space used total if you have many apps installed, yes, but that's the same as bundling .NET with your app

KSP + .NET Native + SSD = omg performance :D

now I really want a 850 Pro

also, I was looking around on the company intranet forums (they're called something other than forums, but they're forums in essence) and it seems that a lot of people are taking matters into their own hands and upgrading their work laptop with more RAM and some even have installed their own SSD, lol

I would've thought that would be against policy, but a lot have done it (....it may still be against policy though)

o.O

4:15 PM

whoa, the 850 Pro 1 TB is down in price :D

I think it MSRP'ed for $700

now it's going for $608

that's pretty awesome that they have made it so affordable.

@allquixotic "affordable" :P

@Bob yeah yeah :P

Windows 10 runs on the Raspberry Pi 2

Official Microsoft Link confirming Windows 10, free on RPi2 (and other microcontrollers)

yesterday, by DragonLord

Raspberry Pi 2 has quad-core ARM Cortex-A7 Processor, will run Windows 10, keeps $35 price tag

I personally thought they would move to a dual-core ARM11 MPCore with slightly faster clocks.

I did not expect a move to ARM Cortex.

Any version of Windows running on ARM is only "Windows" in name, not in function. 99.9% of the advantage of running Windows these days is that foo.exe just works. With all the x86 binaries blocked off, it's not Windows anymore, except in name.

2

it'd be like Honda releasing a "Honda Civic" (with absolutely no brand or product name distinction) that runs on hydrogen fuel cells, and only mentions the fact that it only runs on hydrogen in fine print in the product specs.

imagine the unsuspecting customers trying to fill up the tank at a gasoline station, only to be surprised that the nearest hydrogen station is 2000+ miles away, in California

Please do not forget to run your windows updates on your Honda Civic. Without those it might remain fast.

similarly, imagine the number of unsuspecting customers trying to run foo.exe on "Windows" 10 on ARM

we've already been over this with the MSFT (non-Pro) Surface

with RPi it's just round 2 of the same problem, and yet still, hundreds of millions of people don't understand that Windows on ARM doesn't run x86 binaries.

The old BCM2835 was manufactured on a 40nm process. The new BCM2836 (a custom SoC designed specifically for the RPi2) is probably fabricated on a 28nm process (likely TSMC 28HPM).

6:12 PM

this kind of critical information belongs in the headlines, not in the details

Meh, I do not worrty about fools trying to run software on that.
Not until my job returns to the IT side and they come to me with 'this games does not work on a pi'

6:38 PM

I need to buy new earphones

Hmm PHN-ME323/WH costs 1 USD, I'm getting it

(waiting for @allquixotic go mad in 3... 2...)

> Yep, you can Windows 10 for free on the latest model of the Raspberry PI.

I think there's a missing

6:56 PM

@ThatBrazilianGuy :O you're buying earphones for $1 USD???????

they must have a value of like 10 cents then, right? (because Brazil)

> (because Brazil)

LOL

@DragonLord unfortunately, it's not a joke. :-( it's reality. I really wasn't trying to be funny, hahaha

Yeah, Brazil's taxes are insane

The government is dirt poor, that's why

they bring in plenty of money; it just goes to wealthy entitled families instead of the public coffers

@ThatBrazilianGuy There's a missing what? I need to know, what is missing? You must tell me now!

7:06 PM

@CanadianLuke No, there isn't a missing what. You are incorrect that what is missing.

Try a different.

@allquixotic I know

7:32 PM

ohi

So, wait, is Microsoft killing Windows on ARM completely or are they still going to release it as a product you can get, and they're only killing the (non Pro) Surface?

@BenRichards Windows on ARM is being renamed from Windows RT to just Windows, but it's still going to be available. Everything you said after "or" will be correct.

Oh good :)

Because I still love the idea of Windows on non-x86 processors and being able to run it on things like the Raspberry Pi is a neat idea.

I would love to see the option to have a standard Windows desktop on the ARM side. If only for the selfish reason of being able to do regular console/Windows programming since I'm familiar with that and not have to learn how to do Windows Store apps. :P

Maybe Microsoft should release a console app that runs in metro.

I'd be all over that.

@BenRichards there's no Windows Desktop on Windows RT, AFAIK

unless they're planning to add that to Windows 10 for ARM

@allquixotic I know. That's why I say I'd love the option :P

apparently there's a lot of Windows API that actually got implemented under the hood, but they don't want people to use it

7:40 PM

In Windows 8 it was basically a Windows desktop-esque environment for Office, but not the actual desktop.

aha

I would also love to see the Windows kernel + command line interface shippable as a base package and the ability to add modules on top, like the window manager and so forth. Like we can do with Linux.

No plans to AFAIK but the MinWin effort enables such possibilities.

@BenRichards there's Windows Server Core that comes pretty close to that

Windows is (now!) very modular and separable under the hood, but they don't want to productize just little bits of it :/

Yeah that's what I mean.

I know it is.

they should follow on from open sourcing .NET to also open source Windows :D

That would be interesting.

Maybe at least open source the kernel! :P

yeah, Windows is the only kernel with billions of installed devices that is still closed source

Linux and XNU are open

7:44 PM

I don't see them open sourcing Windows completely, but if they open sourced the NT kernel, that'd be pretty awesome

yup

of course, the worry is that once you suddenly open up millions of eyes onto the source of any major long-term closed-source project, they'll be able to find tons of new security vulns and use them

I think that's a false flag. We have tons of security vulnerabilities anyway coming to light anyway. Microsoft is pretty good at security audits of their code, from what I can tell, though.

they also allow specific people and organizations access to the code to help them review it, but still, once you put literally anyone's eyes onto it, they'll be able to find new bugs more easily -- if there's any low-hanging fruit that hasn't been closed already, especially -- it's only after it's been in the open for a long time that the easy bugs get found and closed and it becomes secure

that's why I don't think that's a problem with Linux -- it's BEEN open, so they've had years to find the defects and get them fixed and closed, instead of there being a sudden deluge

They could roll it out to public eyes over time. Maybe open source it to certain groups first, and then over time grow the group larger and larger. NDA it until it's fully public.

Or maybe Microsoft could support ReactOS and maybe turn it into a parallel open source project, like how you have WINE supported by CodeWeavers, which also sells the closed source form of the software.

heh

except Codeweavers Crossover is literally just a build of Wine with minor resource customizations and a GUI front-end; they don't customize the code at all, they just pick a wine build to ship that looks stable (usually, lately, an actual stable build of wine)

7:54 PM

I keep forgetting about ReactOS.

Yeah I know.

It's "sort of like", really :P

ReactOS/wine could be like GNU/Linux -- that would be funny :P ReactOS for the kernel, wine for userspace

I should try running a ReactOS install.

lol

I experimented with ReactOS a while back. Should try it again. It's been several years.

they have wine running on windows now, last I recall

ReactOS kernel, wine on windows for the userspace

I should find an OS project to support as a hobby. It's just so dang interesting to me. ReactOS and Haiku both seem intriguing as prospects.

Huh, no kidding.

ReactOS is ridiculously complex.... to a programmer it should be a fun playground but also an immense challenge... it's still hard to use it without it crashing frequently

it's impressive that the Linux desktop runs as well as it does, considering how much engineering they put into ReactOS over time and it's still basically a pre-alpha toy

7:56 PM

Well it probably is a complexity that was also shared by Windows.

Yup.

At least Linux is incredibly modular. I don't know the architecture of ReactOS but I assume it has to mimic that of Windows at least somewhat, and there's a reason why the MinWin effort became necessary at Microsoft :P

Welcome to Stack Exchange Podcast #62, recorded live on January 20th–with a live studio audience (kinda)!. Today’s podcast was brought to you by the American Venture Capital Association. With you today are our hosts Jay Hanlon, David Fullerton, and Joel Spolsky.

Let’s jump right in: we made a big announcement! Andreessen Horowitz has invested a pile of money in our little company so we can improve our ‘programmer forums’. Precisely none of the pile of money is going into Jay’s raise, but one of those dollars is going to SomeKittens. …

Looking through their wiki. Really interesting stuff.

Probably would gravitate towards ReactOS more than Haiku since I have no experience with BeOS.

Hard disks (and other things) have a Mean Time Before Failure (MTBF). Usually it says n hours before MTBF. What does that mean? Nothing. The disk can fail the next day you bought it or it can still work when you buy your next computer that doens't support the disk's interface anymore. You can only rely on one thing: it fails just that moment, when you want to make a backup and the previous was 3 month ago. That's why it's called Mean. — ott-- 5 hours ago

That is a brilliant comment.

11:27 PM

> Following the recovery of the flight recorders, on 12 and 13 January, an anonymous International Civil Aviation Organization (ICAO) representative said, "The time has come that deployable recorders are going to get a serious look." Unlike military recorders, which jettison away from an aircraft and float on the water, signaling their location to search and rescue bodies, recorders on commercial aircraft sink. A second ICAO official said that public attention had "galvanized momentum in favour of ejectable recorders on commercial aircraft".

@allquixotic ^

Makes me wonder. Why not include a couple of redundant storage locations?

Then you could also jettison one of the redundant ones.

Yea, cost, of course.

Then again, it should be much easier to make modern storage shock-resistant.

Especially if you consider the older recorders tended to use tape (!).

NAND should be naturally far more resistant to high acceleration.

Fire is a bigger issue, though.

Aircraft are all about redundancy in flight control and sensor systems. Why not add some to the data recorders?

@Bob good point

however, accident investigators are super good at finding the definitive root cause of a crash, even if they don't recover the recorders, just by picking up the broken pieces

it's incredible the ways they're able to analyze busted fragments of metal to come up with answers

the only true mysteries are disappearances where there are no physical traces of the plane, like the Malaysia Airlines plane that disappeared

but a data recorder won't help you there, either

@allquixotic A jettison system might help, though. Locator beacons work far better when they're not under 5km of water.

@Bob cost wouldn't be that much of an issue, I'd think -- there are an enormous number of "sunk" costs already in a plane, adding one more isn't too much to ask

and it's not like we're asking them to add redundant wings or something

And even without jettison, there's been far too many FDR and CVR systems too damaged to read without a lot of work.

@allquixotic And yet, some airlines used to leave out optional (!) things like a stall stick-shaker for the copilot (!).

@Bob I've heard NTSB investigators on ACI say they wish they had the FDR/CVR so they could learn more, but even in those cases, they're able to figure out a lot, and almost always the definitive or very very likely cause

11:42 PM

@allquixotic The other thing I've wondered about.

They previously stored, what, the last 30 mins of CVR audio.

Now it's two hours.

Seems like plenty.

But then MH370 happened... that's three times that in the air.

Once again - modern data storage can easily store a whole day of audio data.

A whole day of CD-quality uncompressed PCM is under 16 GB.

OTOH, that increases complexity...

Hm. Apparently the 2-hour recordings do use solid-state memory.

And they have four channels.

NAND has come a long way in the last 5 years...

@Bob yup

if they used the more expensive SLC, wear might not be a problem for a long time

and they could just replace it every-so-often

> According to this page, tape-based DFDRs can record at 64 12-bit data words per second. Newer DFDRs using solid state recording can store up to 256 12-bit data words per second. This 256 words per second is also specified in the information on this FDR. It says it can record >100 hours at 64 words/second, which translates to about 35 MB total.

So the storage required for the FDR is absolutely trivial.

Probably just comes down to complexity and momentum (change? nooooooooo!!!!)
