@jrg yup, scrolling in chat is broken.

At least it is for me.

TheWanderer

wait

James is jrg again?

Nathan Osman

Dude. U gotta keep up.

TheWanderer

pls

am hav sckul

Nathan Osman

Oh right.

School did start this week.

But that should be a school subject - Social Media 101.

TheWanderer

>_>

uh oh

Michael Bay is here

that means explosions

00:13

@NathanOsman @Avery How much memory should you use with KDE?

Nathan Osman

@TheWanderer And funny camera shots.

@gracious1 At least 1 GB when idle.

Avery

Yeah

gracious1

hmmmm.....

Nathan Osman

My desktop has 16 GB so it isn't a big issue for me.

But for a smaller machine, it could cause issues.

gracious1

Really? 16 GB? I think I only have 8....

TheWanderer

00:15

it's funny how 8GB was a lot like 5 years ago

and now 16GB is really only the good amount to have, not the best

gracious1

Yeah, until this second, I thought it was sufficient. Now I feel left behind again...

TheWanderer

run Android Studio, and you'll know that you need 16GB

@Avery What's so great about it?

Trying to find system requirements....

Avery

@gracious1 i can use it after 5 minutes of changes

With other DMs the same process can take days

(All I do is basically make main panel smaller and replace app list thing with icon only, and set some style options in settings)

gracious1

00:21

@Avery What are sys requirements?

Avery

Idk but you need like at least 4 gigs to not get system to choke

Like kde doesn't use it all obviously

gracious1

Grrrr... why is Fx 52 ESR eating up my CPU?

Avery

well I'm off to sleep

Hey, Steam runs on Arch without any modifications.

No need to mess with LD_PRELOAD.

jrg

Yeah, I'm jrg again @TheWanderer

There's another mod named James and it was just getting confusing in the top secret mod chatroom

(on another site)

Nathan Osman

Which totally doesn't exist.

What were we talking about again?

jrg

so I decided to change my name and put an end to my inbox full of messages intended for someone else

gosh scrolling being broken here makes it almost pointless...

has anyone made a user script for it yet?

Nathan Osman

IKR?

Is it fixable?

jrg

actually do the devs know?

Nathan Osman

01:17

Want me to ping someone?

jrg

I'm surprised someone hasn't already

ok so i found some JS on the internet that will scroll down

now i just need to write something that will tie it into the 'new message' event

which has to exist lol

either that or infinite loop it on a timer...

Nathan Osman

Wait until you see what userscripts have to do to "hook" new message.

jrg

Yeah I'll probably give up then

lets see if it's broken for anon not-logged in users

nope, my firefox scrolled just fine. my chrome is def broken though.

Nathan Osman

I pinged someone. Oh, you saw that already :P

jrg

I saw

i've been providing commentary lol

Eliah Kagan

01:25

Does this actually work? (It doesn't for me, but I use Lubuntu.)

Nathan Osman

Don't look at me - I'm not even using Ubuntu anymore :P

Eliah Kagan

Arch?

Nathan Osman

Yup.

Eliah Kagan

I would expect this might vary across desktop environments but, aside from that, not much across distros.

How are you liking Arch btw?

jrg

Not working for me on Fedora

with gnome shell

Eliah Kagan

01:27

Does it work if you drop the leading $ in the assignment? I think that's a typo. In a Bourne-style shell it would certainly be a typo. (It doesn't work for me at all in Lubuntu, even just enclosing the command in ( ) makes it say the .desktop file is bad.)

jrg

i'm trying it straight from my shell

oh

there's a typo

try (LC_NUMERIC=de_DE.UTF-8 gnome-calculator) @EliahKagan

the semicolon shouldn't be there

Eliah Kagan

What what I'm looking to know is if a .desktop file can use this syntax.

jrg

it should

i'll try the .desktop, but there was a syntax error with that semicolon...

Eliah Kagan

The text on the Exec= line of a .desktop file doesn't run in a shell, does it?

jrg

I'm not 100% sure

Eliah Kagan

01:29

So if ( ) works in a desktop file, does it mean something besides a subshell?

jrg

it's been a long time since I played with it

Eliah Kagan

I'll try on Lubuntu without the ;.

I get the same error without the semicolon. Of course it would work from the shell, but it doesn't work in a .desktop file. On my Lubuntu 16.04 LTS system anyway.

I also tried replacing the ( ) with ' ' and, separately, with " ". None work for me. (That's a stretch away from what the answer says to do anyway though.)

jrg

It's not loading the desktop file for me in GS

i even logged out and back in

Yeah

i can't make it work

although it might be because the desktop file isn't showing up for me

Eliah Kagan

It isn't showing up?

jrg

Yeah

must be a syntax error

but I've no idea where to find logs for this

Eliah Kagan

01:35

You mean you can't see the file at all, when you look in the folder that contains it?

jrg

No, it doesn't show up in my launcher

Eliah Kagan

If you make it executable, you should be able to run it from Nautilus by double-clicking. .desktop files work for me this way (in LXDE with PCManFM instead of Nautilus), they just stop working when I add parentheses or do anything that attempts to treat the first word after Exec= as anything but the name of the command to be run.

jrg

ok, one sec

i'll try that

TheWanderer

scrolling is broken where?

jrg

@EliahKagan no luck

it just says "there was an error launching the application"

trying a bunch of variations and permutations of it

yeah no luck

Eliah Kagan

01:42

But you're able to make a desktop file that does work when you run it that way, right? Just not with this environment variable setting syntax?

jrg

yeah

if i copy it, chmod +x it and double click it it runs

but if I edit this stuff it errors

Eliah Kagan

Yeah.

The env command facilitates setting environment variables in a .desktop file, so this works:

[Desktop Entry]
Encoding=UTF-8
Name=Foo
Exec=env FOO=foo xterm
Terminal=false
Type=Application

But the ( ... ) syntax, I can't get that to work.

jrg

yeah, me either

Kaz Wolfe

hey, @NathanOsman, are you around?

Eliah Kagan

Even when I set Terminal=true and use Exec= to run a terminal command, I get the same "Invalid desktop entry file" error. I don't think .desktop files ever support shell syntax.

Thanks for trying this! (I didn't have any GNOME systems available at all.)

jrg

01:48

You're welcome!

signing off for a bit to do some blogging/writing

later

Eliah Kagan

Cya!

Kaz Wolfe

disregard - got it

Nathan Osman

02:04

@KazWolfe yes.

Kaz Wolfe

sorry, figured it out. some stupid shell thing

Nathan Osman

I'm trying to find a nice GTK2 theme.

Absolute + Numix borders looks nice.

Nathan Osman

02:30

Things I like about Arch - packages are really up-to-date.

I hope makepkg is doing shallow clones.

Android Dev

@NathanOsman btw, have you tried revoking the storage permission while Nitroshare is doing a transfer?

I haven't tried it but I expect the results wouldn't be pretty

Nathan Osman

02:49

@AndroidDev I imagine it would only crash if the transfer had more than one file.

I don't think changing permissions affects already-opened files.

And to be honest, I don't really think it's worth writing code to work around someone revoking permissions while an app is in use.

Actually.

If I remember correctly, there are exception handlers in the file reading/writing code.

So most likely, it wouldn't crash, the transfer would just fail.

Hmm... I might give this a try to find out.

@ByteCommander I'd need to examine the headers on your system that's rejecting the email message. It will usually specify which SPF record it was trying to verify and failed to verify on.

Nathan Osman

Whoa.

So my entire LXDE desktop with a terminal open is using 500 MB of RAM.

That's a definite improvement. Of course it vaporizes when I start Chrome.

Thomas Ward

@ByteCommander Ah I didn't see your earlier message. The issue is your SPF record for your home.com domain. You need to add the following to your SPF record for permitted senders: mx:uni.com as an additional item in your SPF record; that will say that uni.com mail servers are permitted to send or relay messages on behalf of home.com.

Nathan Osman

Why don't more desktop environments allow you to choose which keys are modifiers?

I don't use super for anything. I just want to use it on its own.

Le sigh.

@terdon I just generally strip all metatags

terdon

@blade19899 Why?

And even from random images you found online? (I assume that isn't actually Rinzwind and his dog)

I mean, all I see is this:

File Name                       : oGrd8.jpg

Why is it worth removing? Just to make the image smaller?

blade19899

@terdon I actually did assume it was Rinzwind and his dog xD

@terdon Ditto. Kudos for knowing about exiftool, not allot of people know of it.

terdon

@blade19899 Oh, I wish. If it were, I'd be on the next plane to Holland begging Rinzwind to let me play with that gorgeous beast!

TheWanderer

@blade19899 OK, so what is worth removing there? I'm just trying to understand why you would bother to remove anything.

TheWanderer

I also thought Imgur stripped metadata

blade19899

@terdon No real privacy related reason. Stripped metatags is good for your pagespeed if you use them on websites. I think thats why I generally strip them.

Nathan Osman

Hey, cool.

Suspend actually works in Arch :P

terdon

@NathanOsman What are you doing on the dark side?

Nathan Osman

It's not actually that bad on this side.

2s boot times, lightning-fast package installations...

Avery

Yes

That's why I love arch.

Also everything is updated to the new versions often, unlike ubuntu.

terdon

@NathanOsman You're preaching to the choir. I've been using Arch for 2 years now.

Android Dev

15:56

@NathanOsman wat. 2 second boot time? O_O....... GRUB takes 7 seconds to load the flipping kernel from my SSD!

Avery

@AndroidDev use systemd-boot

Android Dev

@Avery eh?

what's that?

terdon

Don't use grub

You don't need it on EFI systems

Android Dev

and I thought everybody hated systemd?

@terdon but uh... I hate UEFI so i installed in Legacy :P

terdon

Ah well

Avery

15:59

why do you hate uefi

also that explains the 7sec kernel load times

Android Dev

no it doesn't

Nathan Osman

I don't hate EFI but I was too lazy :P

Android Dev

my SSD reads at 550MB/sec

Nathan Osman

When I say 2s, I'm not counting the grub handoff.

I'm just referring to the kernel starting.

Android Dev

ok, because my POST takes 2 seconds :P

Nathan Osman

16:00

My BIOS lets me customize the time the POST logo is displayed.

So if it bothers me that much, I can almost make it disappear.

Android Dev

right, I don't have it show the logo, but it still takes a bit after hitting the power button before anything is displayed on the screen

Nathan Osman

The biggest delay for me is my LG monitor - it takes about 5 seconds to recognize a signal and turn on :P

Granted, the signal is over DVI using an adapter.

Android Dev

@terdon @Avery Correction - it takes 7 seconds for the initrd to load... the kernel only takes 1 seconds

Avery

eh use arch

and uefi

Android Dev

the initrd image it's loading is 36MB. So if it took 7 seconds to load, then it's only reading it at 5MB/sec!

Avery

16:02

see the difference

Android Dev

5MB/sec on a 550MB/sec SSD!

Avery

it's not just about reading but actually doing stuff y'know

Android Dev

@Avery ahem the disk I/O light stays on for the entire 7 seconds

Avery

don't believe the disk I/O light's lies

Android Dev

Interestingly though, it isn't at it's full brightness

and no it's not just the picture :P

@Avery but I think the real problem is GRUB doesn't like the AMD970 chipset's SATA controller. I removed the SSD from my desktop, and temporarily put it into my Dell Latitude laptop. Lo and behold, it loaded the initrd much faster, shaving 6 seconds off the boot time...

Avery

Android Dev

@AndroidDev Well, everyone except the devs of some minor, obscure distros like Ubuntu, Debian, Arch, RedHat, CentOS. . . :P

yes you told me

but it's public

I wonder if they'll support 8.1.

TheWanderer

I guess LOS might have early access to source now

@NathanOsman lol

Nathan Osman

They only said they'd quit before Android P.

TheWanderer

that means 8.0.0

you know what's sad? The OP2 has Oreo from LOS now too

What would you say is the minimum amount of RAM required to run Oreo / Nougat?

2 GB?

Maybe even 1?

TheWanderer

well my RAZR M does reasonably on LOS Nougat

I think it's 512MB?

Nathan Osman

Well then.

TheWanderer

no 1GB

Nathan Osman

How long ago since phones began shipping 1 GB of RAM?

Avery

@TheWanderer ew

TheWanderer

16:52

@NathanOsman 2011

looks like

Nathan Osman

So six years then.

Vendors could reasonably support phones for six years.

And quite frankly, I think the wear-and-tear after six years necessitates an upgrade anyway :P

TheWanderer

with the way phones are going, most people crack the back of the phone really quickly

Nathan Osman

The one advantage of the Essential phone.

Le titanium.

TheWanderer

I think the Mi Mix is the same build variety

Nathan Osman

This doesn't sound good.

Can't even open the phone up without breaking it...

TheWanderer

Nathan Osman

That's one thing I miss about earlier phones - they were easy enough to repair. I mean... you used to be able to remove batteries :P
