@NathanOsman It's pretty sad when you have to reformat someone's code before you can even read it..

Nathan Osman

@AndroidDev Not everyone has the gift of formatting :D

Android Dev

@NathanOsman I cringe when I see people at the library "centering" text in Word by holding down the space bar...

Nathan Osman

Or even using tabs to align text.

That's not what tabs are for!

Android Dev

And I also cringe when I see people using CAPS LOCK for just one letter...

Nathan Osman

Drools more...

128 GB of RAM ought to be enough.

Even Chrome couldn't possibly use up all of that.

Android Dev

00:04

@NathanOsman I don't know if they're still this cheap, but the e5-2670 8-core CPUs go for $80 used on Ebay

Nathan Osman

Brand new ones are $169 on ebay.

So I can believe that.

Sergiy Kolodyazhnyy

Verilog is getting on my nerves right now

Nathan Osman

What happened?

Sergiy Kolodyazhnyy

I wrote a module for 8-bit counter. I can't see any possible error. Everything compiles. And yet when I simulate it, the counter stays at 0

I've no idea what to do about this

Android Dev

00:29

@NathanOsman - If I take a file licensed under GPL that's 1,800 lines and trim it down to something that's only 350 lines and also change it up quite a bit, do I still need to release it under GPL?

Kaz Wolfe

judging by how non-free and draconian the gpl is, yes.

TheWanderer

hue

@NathanOsman why

Android Dev

@KazWolfe sigh why can't everything be Apache or MIT?

TheWanderer

oooh

Kaz Wolfe

@AndroidDev because reasons.

TheWanderer

00:31

I wonder if I can nest separate if conditions in a ternary...

@KazWolfe raisins*

Kaz Wolfe

yes. you can. no, you shouldn't.

TheWanderer

@KazWolfe I think I will :D

Kaz Wolfe

nested ternaries are hard to read.

TheWanderer

ternaries are hard to read

Kaz Wolfe

small ternaries are easy to read.

nested ternaries are not small.

TheWanderer

00:33

what about with parentheses

Kaz Wolfe

(count != 1) ? "s" : ""

easy to read.

whatever hell you're thinking of is pretty much guaranteed to not be easy to read at this rate.

TheWanderer

count != 1 ? (count == 2 ? "2" : "not 2") : "1";

:D

Kaz Wolfe

don't do that.

Android Dev

@KazWolfe Hey that's my line :D

Kaz Wolfe

and i used it on you. gg

TheWanderer

00:37

geegee

gheeghee

Nathan Osman

@TheWanderer Because it guards against errors.

edwinksl

@TheWanderer hue never

Nathan Osman

What happens if you add another statement and forget to add braces? Boom!

App goes up in smoke.

TheWanderer

@NathanOsman I just put the whole thing on one line

@NathanOsman or you know, the IDE doesn't indent so you realize something's weird

or you can't find the closing brace

@edwinksl pls

Nathan Osman

One accidental semicolon and boom!

Sergiy Kolodyazhnyy

00:39

@TheWanderer My professor knows that well . . . I wrote one of the answers in ternaries on the last exam . . . I don't think he undrestood what I wrote at all

TheWanderer

lolol

Nathan Osman

if (myVar >= 12 || myVar <= 24); doSomething();

^--- see the problem?

TheWanderer

who would put a semi-color right after the if statement?

Sergiy Kolodyazhnyy

Also, hooray ! I found the error in the simulation. The module was instantiated with input and output variables in wrong order

TheWanderer

@SergiyKolodyazhnyy forshame

Nathan Osman

00:40

@TheWanderer someone with careless typing.

...who did it by accident.

TheWanderer

@NathanOsman you?

Nathan Osman

ಠ_ಠ

Sergiy Kolodyazhnyy

@TheWanderer foreach (var in lab) mess_up(var);

Nathan Osman

Son, I am disappoint.

Sergiy Kolodyazhnyy

Look at those smexy square waves

Nathan Osman

00:41

@SergiyKolodyazhnyy That looks pretty intense.

TheWanderer

mmmmmm

@NathanOsman u no it

Kaz Wolfe

seriously. braces are important. Nathan is right there. There is maybe one use case for no-braces, but that's return. And even then, don't.

Nathan Osman

E: cannot parse "u no it" - statement could mean "you know it" or "you are not 'it'"

Sergiy Kolodyazhnyy

Kinda is intense. Well, now I better write a lab report . . . I don't think I'll have time to test it on hardware

TheWanderer

@NathanOsman take it as you will

Nathan Osman

00:42

Lol.

TheWandererParser v2.0 - ambiguous as can possibly be™

TheWanderer

@KazWolfe what about in an excercise to condense a Java program into as few lines as possible?

@NathanOsman jue

Nathan Osman

@TheWanderer golfing?

Kaz Wolfe

@TheWanderer Don't do that.

Nathan Osman

We have a site on the network for just that purpose.

TheWanderer

@KazWolfe was an assignment

Nathan Osman

00:43

Kaz Wolfe

Java is not a minifiable language.

TheWanderer

@KazWolfe oyes it is

ProGuard!

Kaz Wolfe

Minifying java is a bad idea.

TheWanderer

Java is a bad idea. Why not make it worse?™©®

Q: Tips for golfing in Java

Are there any useful shortcuts that can be used in Java? As shown below, import already adds at least 17 characters to a program. import java.io.*; I understand that the simple solution would be to use another language, but it seems to be a real challenge to shorten Java programs. Tips...

Nathan Osman

00:43

@KazWolfe Not without murdering various parts and making your ~~victims~~ users screech in horror.

Sergiy Kolodyazhnyy

You're welcome @TheWanderer @KazWolfe

Kaz Wolfe

Java is a decent language. You're using it wrong.

Nathan Osman

@TheWanderer If you would have combined that into a single message, I would have starred it.

TheWanderer

viola

Nathan Osman

There.

Has a star.

Lol.

I see those suffixes...

TheWanderer

00:45

:>

Nathan Osman

U is evel genius

TheWanderer

yehssssss

Nathan Osman

Goes back to writing Go...

TheWanderer

Chat please

Kaz Wolfe

TheWanderer

00:45

5 seconds to edit

Nathan Osman

We don't have to worry about any of this stuff with Go - the compiler forces a coding style on everyone.

TheWanderer

@KazWolfe go away Python

this is Java Time

Nathan Osman

...aaaaand Java time is up.

Kaz Wolfe

on another note, my office just got everyone in engineering really nice jackets.

TheWanderer

@NathanOsman well I'm sure if I decompiled my app I'd see some pretty good optimization ideas in the Smali

Nathan Osman

00:46

@TheWanderer You'd also see Cthulu or something.

TheWanderer

I might

Nathan Osman

Maybe you'd find fragments of Perl.

Kaz Wolfe

that's why the compiler exists. to minify your code. you don't with java.

TheWanderer

would confirm @edwinksl's suspicions

Nathan Osman

The compiler compiles the code.

TheWanderer

00:47

@NathanOsman WHAAAAAAT

Nathan Osman

It converts source files into an intermediate form for the JVM.

TheWanderer

GAHHHHHH

Nathan Osman

@TheWanderer Yes, I know.

TheWanderer

7 SECONDS TO EDIT

Kaz Wolfe

which also optimizes them and does some minification.

TheWanderer

00:47

Help pls

Nathan Osman

javac Reads Source Files - You Won't Believe What Happens Next

^--- if programmers worked for BuzzFeed.

TheWanderer

@KazWolfe oh go away with your silly "standards"

@NathanOsman the body would be in binary

Nathan Osman

That wasn't nearly as funny as I expected it to be.

edwinksl

@TheWanderer XDXDXDXD

Nathan Osman

It's only Tuesday.

TheWanderer

00:48

so tired

Nathan Osman

Kaz Wolfe

ooh, free lunch time :D

Nathan Osman

Free as in beer? :P

Kaz Wolfe

да

edwinksl

speaking of wednesday, first episode of american gods was pretty good

Nathan Osman

00:51

13/10 would have lunch again

Kaz Wolfe

hm.. we need a flame war.

Source Film Maker is better than Blender.

Sergiy Kolodyazhnyy

@KazWolfe don't we argue about vim vs nano vs emacs vs <insert someone elses text editor here> already ?

Kaz Wolfe

@SergiyKolodyazhnyy atom wins.

Nathan Osman

@KazWolfe NopeNopeNopeNopeNopeNopeNopeNope.

Blender can do anything.

And it can do it better.

Kaz Wolfe

can blender make me coffee?

that i can drink in the real world?

Nathan Osman

00:54

Even the name itself should answer that question.

"blender"

edwinksl

solid reasoning

Nathan Osman

Y'know, for grinding coffee beans.

Kaz Wolfe

can blender solder a cpu?

Nathan Osman

If you enable GPU rendering in cycles, I'm sure the heat from your GPU is sufficient for that.

Journeyman Geek

With a little hacking....

WILL IT BLEND?

Nathan Osman

00:55

LOL.

Reason #196 for liking Blender - Oracle hasn't bought it yet.

:P

Sergiy Kolodyazhnyy

Wrong blender, but still funny

Kaz Wolfe

can blender replace my broken glass pane?

Nathan Osman

Yus.

@KazWolfe you broke your Windows?

You should switch to Ubuntu.

Kaz Wolfe

@NathanOsman no

Nathan Osman

It is much better.

Kaz Wolfe

00:57

i don't have windows on any computer anymore.

Nathan Osman

Then how can it be broken? :P

Kaz Wolfe

actual glass.

Nathan Osman

Google Glass?

(I'm feeling my troll coming on...)

Kaz Wolfe

so blender can't is what you're saying

got it

Nathan Osman

(And remember that you started this by insulting Blender :P)

@KazWolfe And Source can totally do that, I'm sure.

Kaz Wolfe

01:00

no no, you've made your point. blender can not replace glass.

no need to keep repeating it

Nathan Osman

Okay. Fine.

Next on the agenda.

Tabs are infinitely superior to spaces.

Prepares defence shields...

Kaz Wolfe

they are.

in fact, my git server considers them so great that it replaces tabs with spaces in order to preserve the glorious stature of tabs, keeping it out of peasant code like my own.

only true masters of coding are worthy to use tabs.

Android Dev

LOL!

Nathan Osman

Oh brother...

:D

TheWanderer

01:19

tabs are more convenient

and spaces introduce more fragmentation in style

I'm always annoyed when I have to deal with 1-3 spaced indents

UHH

Why is GSMArena down?

@NathanOsman what did you do

Nathan Osman

@GeorgetheDev is www.gsmarena.com down?

George the Dev

@NathanOsman www.gsmarena.com works for me

Nathan Osman

See, @TheWanderer, you made it up :P

TheWanderer

yeah it just came back up

Nathan Osman

Lol.

TheWanderer

01:25

I'm still suspicious >_>

Nathan Osman

Convenient.

TheWanderer

isup.me told me it was down, and I was just about to go find another site, when I saw it had refreshed

Kaz Wolfe

isup.me/isup.me/isup.me/isup.me/isup.me/isup.me/isup.me/isup.me/…

TheWanderer

@NathanOsman you know what's fun?

T-Mobile got the 600Mhz spectrum in the US, and you're still stuck on 3G :D

Nathan Osman

Yeah, yeah, yeah.

Kaz Wolfe

01:29

600mhz is gonna be somewhat slow, no?

Nathan Osman

Digital Ocean just gave me $1 credit.

TheWanderer

I might actually wait until 2019 to get a new phone, instead of November 2018, so I can have 5G

@NathanOsman WHOA THERE

@KazWolfe better than Edge, no?

and better than nothing

Nathan Osman

@TheWanderer Apparently it's for SLA at SF2.

I guess I had a droplet running there.

TheWanderer

and I'm HFL with a FHD at 5TG

Nathan Osman

#AcronymAbuse

TheWanderer

01:31

you started it

Nathan Osman

@TheWanderer SLA = service level agreement

TheWanderer

Nathan Osman

The guarantee a certain level of uptime.

And I guess they give you refunds if they don't meet it.

TheWanderer

interesting.................

so anyone want to try out my ~~malware~~ app?

Nathan Osman

Er... not at the moment.

Checks antivirus subscription.

Kaz Wolfe

01:33

sure why not

TheWanderer

github.com/zacharee/DPIChanger/raw/master/app/app-release.apk

Nathan Osman

Y U NO USE PLAY STORE?

TheWanderer

@NathanOsman IZ NOT RELEAS YET

Nathan Osman

USE ALPHA FEATURE

TheWanderer

I need to get an icon and feature graphic

Nathan Osman

01:37

TheWanderer

and the Play Store takes forever to publish

PLS

Nathan Osman

Fine, whatever.

TheWanderer

besides, my stuff is open-source, so the APKs get pushed to GitHub anyway

Kaz Wolfe

wtf is UBE?

and organization XPW?

TheWanderer

second result in Google for "UBE PA" will tell you

Kaz Wolfe

UBE Industries, Ltd?

TheWanderer

@KazWolfe my initials, my sister's initials and my dad's initials are all *PW

@KazWolfe second result, the Wikipedia one

Kaz Wolfe

01:41

why not just spell out the full town name?

TheWanderer

Upper Black Eddy pleb

Kaz Wolfe

01:55

from a legal standpoint, yes. the GPL requires that any modified GPL code be copylefted. And as you're technically modifying that code....

(IANAL)

Android Dev

Humpf

Kaz Wolfe

my advice: write some code that performs similarly.

Android Dev

Yeah

It's only 200 lines after all

Nathan Osman

02:30

That's not a lot for Java >:)

Also, I wish there was a way to get Launchpad to notify you when a new version of a package is added to proposed.

something with graphics card not being recognized

Nathan Osman

Interesting...

But it works with the latest stable branch. It only does that when I switch to the master branch.

Argh. I switch to Enlightenment and I am mysteriously logged out of everything.

Nathan Osman

05:29

I patched it to make the editor run.

Still locks up the GPU, this time hard resetting the PC.

Okay. UnrealEngine is truly and officially not happening on Linux on this PC.

And the radeon driver should never be vulnerable to a userspace program that can crash the entire system.

But somehow this kernel got tainted.

Shh... don't tell anyone but I'm really thinking Nvidia next time I buy a GPU...

Journeyman Geek

hah

nvidia is pretty good

but ironically, the best graphics support on linux is intel

Nathan Osman

05:45

I know.

My laptop has Intel graphics.

But Intel graphics just don't cut it for OpenCL.

Also, Windows is stupidly annoying. Every time I kill the update process it respawns.

I DON'T WANT TO UPDATE NOW.

I just want to download files. Stop stealing all the bandwidth!

user136984

Because I have a machine with it on and would like to know if it is stable enough yet to upgrade to?
