government forms = madness

TheWanderer

Android == madness

WinEunuuchs2Unix

Android == Linux 3.13?

Nathan Osman

3.18 for me.

OxygenOS :D

Android Dev

@WinEunuuchs2Unix Depends on the version

@TheWanderer no

WinEunuuchs2Unix

My Android has been crashing this last week... sound static spike in music player requires reboot. but today chrome just crashed on a website and I had to reboot because of that. Haven't had an OTA system update in a while though. Strange...

Android Dev

12:14 AM

Which phone do you have?

WinEunuuchs2Unix

Alcatel One Touch Idol 3 5.5"

Android Dev

Alcatel? IMHO that brand in junk :\

Nathan Osman

> In the case of shared records, a host MUST send a "goodbye" announcement with RR TTL zero (see Section 10.1, "Goodbye Packets") for the old rdata, to cause it to be deleted from peer caches, before announcing the new rdata.

AHA.

WinEunuuchs2Unix

Yeah but it's cheap :D And the stereo speakers plus 1920 screen is very nice.

Android Dev

You can get a brand new in box sealed N5 for $150

WinEunuuchs2Unix

12:16 AM

And it has a built in radio tuner which is nice for work.

If I buy another phone it'll probably be the Idol 4 because the stereo speakers are an extra .2 watts.

I basically use my phone as a music player for the most part. Maybe 2 or 3 text messages a week.

Android Dev

Nah, buy a quality brand like the Moto G4 play

WinEunuuchs2Unix

Well of course I use it for internet and Stack Exchange too when in transit.

Android Dev

not some cheap Chinese junk with pre-installed malware

WinEunuuchs2Unix

I looked at the Moto.

The price was similar but it had fewer features.

I hope Ottawa and Washington win.... That would be a cool series between those two.

Nathan Osman

But my beloved Penguins :P

Anyone remember this?

May 2 at 7:02, by Nathan Osman

I went a bit overkill for my next render. 16-bit PNGs at 60fps - in DCI 4K.

Well, it may actually be finishing tonight.

All four seconds of footage.

TheWanderer

12:35 AM

o_O

Android Dev

@NathanOsman What are the CPU/GPU temps like?

Nathan Osman

@AndroidDev Good question.

The GPU isn't in use at all, since it's an integrated Intel GPU.

But let's find out about the CPU.

Android Dev

I mean, it's been going for 6 days, so... it might be quite toasty by now

(considering it's a Mac mini)

Nathan Osman

The case is very warm to the touch.

But that's normal when the CPU is in use.

Android Dev

Is the fan going at 6,900RPM?

Nathan Osman

12:38 AM

I can't hear anything.

Sergiy Kolodyazhnyy

bleh

Nathan Osman

The Mini is very silent.

Even under full load.

Android Dev

@NathanOsman osxdaily.com/2011/07/11/…

Sergiy Kolodyazhnyy

exam went just like i expected

total bleh

Android Dev

Yeah, but you know some of Dell's laptops that used the 1st gen Core i chips would get up to 90c before the fan went to full speed

Nathan Osman

12:40 AM

That's not good.

Apple builds everything themselves though, so I assume they have taken thermal properties into consideration when designing the case.

They have a custom-built motherboard.

(Trust me, I know. I took one apart.)

Android Dev

No. But then again don't you remember the screenshot I showed you a while back when I was rendering a video on my laptop? 100C and the CPU was still turbo-boosting

Even the newer ones aren't great

Nathan Osman

Yes, laptops can suffer from that for sure.

@AndroidDev ---^

Android Dev

Yeah, but I mean having two cores at 102C and you're it's still boosting to 3.5Ghz? The base speed is 2.7Ghz and the thermal shutdown is 105C Tjunction

@NathanOsman Not bad at all

Nathan Osman

People should start to worry when their CPU exceeds 70° C.

That might not be a problem but if it climbs much higher, it can cause problems.

Android Dev

@NathanOsman For AMD desktop chips, yeah, but the Intel chips especially in laptops are good up till 80-85

Nathan Osman

12:45 AM

The only component in your PC that should be hotter than 80° C is your GPU.

@AndroidDev Oh?

That's good to know.

I didn't realize Intel chips could tolerate higher temperatures.

Android Dev

Yeah, the FX series aren't supposed to get hotter than 75

And the AMD laptop chips can't really take the extra heat either

Nathan Osman

Yeah, the fans go nuts on mine when the temperature gets close to that number.

Android Dev

I don't own one, but I've heard that it's perfectly normal for an AMD R9 290X to be running at over 95C....

Nathan Osman

I have a 270X.

Android Dev

Who needs a heater if you have one of those things?

Nathan Osman

12:47 AM

And yes, it can get every bit that hot.

:P

I don't even worry until it hits 105° C.

And if you thought the fan on my CPU was loud...

Having both fans going is very, very noisy.

Android Dev

Just for the heck of it, I pushed my FX-6300 to 4.7Ghz to see how high of a Cinebench score I could get...

But I immediately brought it back down

No need to wreck the VRMs

Nathan Osman

Have you ever tried liquid cooling?

Android Dev

I was surprised at how well the Hyper 212 Evo cooled it.

It could keep it at just over 75C when running Prime95

Of course, I only ran it that hot for like 60 seconds

But no, I haven't tried any AIOs because I'm afraid of what might happen if it leaks

And building your own custom loop is just way to expensive

Nathan Osman

Boom!

Android Dev

Done?

Nathan Osman

12:51 AM

Actually, it might not be all that bad.

I imagine they fill the tubes with distilled water.

So if it leaked, the damage may not be quite as significant.

TheWanderer

ANDROID WHY CANT YOU JUST LET US USE THE HIDDEN APIS

Android Dev

But distilled water will still pick up the impurities in short order

Nathan Osman

@TheWanderer Shouldn't the real solution be not to hide them?

@AndroidDev Hmm... true.

TheWanderer

@NathanOsman well yeah

that's part of letting us use them

this Gradle build is taking forever....

Android Dev

@NathanOsman But why go liquid when you could get this?

That thing probably weighs 5LBS!

Okay, maybe not that much...

TheWanderer

12:54 AM

o_O

Nathan Osman

O_O

That is going to freeze the CPU.

:P

Android Dev

And it's only $80 too

Nathan Osman

I also imagine it isn't quiet...

Android Dev

It's a Noctua, so it's supposed to be really quiet

Or wait, how about you put a JET ENGINE on your CPU?!

TheWanderer

that's not a jet engine

Android Dev

12:58 AM

I know :P

HOLY COW!

12 Delta fans!

►

@NathanOsman Those fans use more power than your entire computer! --^

(In the vid)

That's how you cool Pentium 4s, AMD FX-9590s, and Nvidia GTX480s, people

@NathanOsman This however, will legitimately freeze your CPU:

TheWanderer

1:50 AM

WOOHOOO

@KazWolfe I made an abomination hybrid of using a modified android.jar to access hidden APIs and reflection

IWindowManager iWindowManager = IWindowManager.Stub.asInterface(ServiceManager.checkService(Context.WINDOW_SERVICE));
        Class<?> iw = iWindowManager.getClass();
        if (SDK_INT > 24) {
            iw.getMethod("setForcedDisplayDensityForUser", int.class, int.class, int.class).invoke(iWindowManager, Display.DEFAULT_DISPLAY, Integer.getInteger(newDPI), 0);
        } else {
            iw.getMethod("setForcedDisplayDensity", int.class, int.class).invoke(iWindowManager, Display.DEFAULT_DISPLAY, Integer.decode(newDPI));

Nathan Osman

chance_of_summoning_cthulu += 50

TheWanderer

lol

so here's a question

why does Android 4.3 need the WAKE_LOCK permission to use reflection??

Nathan Osman

2:06 AM

Wat.

TheWanderer

exactly

Kaz Wolfe

WHAT THE

Nathan Osman

Something doesn't sound right about that.

Kaz Wolfe

if (SDK_INT > 24) {
    methodName = "setForcedDisplayDensityForUser";
} else {
    methodName = "setForcedDisplayDensity";
}

Also don't define iw, just use iWindowManager.getClass().

TheWanderer

2:25 AM

@KazWolfe that .getClass() didn't work for some reason

that's why I have the separate values

because, ANDROID

Android Dev

@NathanOsman So how does the render look?

@KazWolfe Do we allow questions asking for help setting up a hacking tool? askubuntu.com/questions/913257/metasploit-wont-launch

@KazWolfe and the methodName thing won't work

because each method takes a different number of args

What's up with that?

Nathan Osman

Or on an actual device?

Android Dev

The emulator. But it works fine on my Nexus 7 on MM

Just now firing up the Nougat emulator to see what happens there

@NathanOsman Works fine on the Nougat emulator

Nathan Osman

What does res/drawable/ic_photo_black_24dp.xml look like?

Perhaps something in the XML is causing problems.

Android Dev

Nathan Osman

3:04 AM

Well that was easy to diagnose :P

> "Android 4.4 (API level 20) and lower doesn't support vector drawables."

You'll have to use PNG to support 19 or lower :(

Apparently there's some support library you can use.

developer.android.com/studio/write/vector-asset-studio.html

Android Dev

Wat.

Android Studio didn't warn me?

Nathan Osman

That's weird that it didn't warn you.

It's usually pretty good about that.

Android Dev

It can warn about memory leaks but not that my minAPI doesn't support some calls?

Nathan Osman

¯\_(ツ)_/¯

Android Dev

Thanks for the help. Unfortunately I've got another wat situation here:

how does that return null?

Android Dev

@NathanOsman How did the render turn out?

Or do you still have to render all the frames into a video?

Nathan Osman

@AndroidDev It turned out quite well.

Turns out I didn't have PNG compression set as high as it could be.

So each frame is a bit larger than it needed to be but that's okay.

13 GB is a lot but not compared to the 2 TB drive it's stored on.

Android Dev

I thought PNG was uncompressed?

Nathan Osman

It is lossless, but it does support varying levels of compression.

The more you compress it, the more time the PC spends on it.

Android Dev

Sorta like archiving a file?

Nathan Osman

5:11 PM

Yes.

Byte Commander

So it should work best for drawn stuff with big areas of solid colors.

It's a 16-bit PNG though. 4096 × 2160.

16 because 8 RGB + 8 A?

Nathan Osman

Nope, each channel is 16-bits.

Android Dev

Oh, okay, yeah, I was kinda confused there for a second :D

Nathan Osman

That gives me the ability to push the image through a program like RAWTherapee and touch up the color afterward.

Android Dev

So how long do you think it takes to render a fully animated movie?

Nathan Osman

It was interesting because ffmpeg wanted to use yuv444p when encoding the video. Which is fine except few video players are capable of decoding it quickly enough. So I had to manually specify yuv420p.

Android Dev

@AndroidDev Depends on the type of video.

The difference between Big Buck Bunny and something similar to a Pixar film is quite large.

Though I do wonder how long it took to render BBB in 4k @60FPS
