hmmm

huh it comes with USB-C

2:18 AM

@NathanOsman you'd know this. Is Mini-DP what Macs used to use?

@TheWanderer yes

Avery

@TheWanderer not all macs use minidp but most have a minidp port

used the same jack as thunderbolt

thanks, Nates

or rather vice versa

2:22 AM

so if I need to, I can just use the Mac adapters we have lying around for this laptop, if I get it

I mean, it's only $9 to get a full on mDP to HDMI cable from Amazon, but still

Thinkpad?

Those often have miniDP too

generic amazon.com/N850HK1-1920x1080-i7-7700HQ-Bluetooth-Warranty/dp/…

seems pretty good to me

a generic laptop...?

it has three outputs, which I really like

That doesn't raise red flags..

2:24 AM

@Seth it's a brand, but it's custom built. Two brands sell the same model.

idrk how that works

but looking at the Q&A and reviews, CS seems super responsive

wait a minute...

@DᴀʀᴛʜVᴀᴅᴇʀ Aren't you a room 240 person >_>

DᴀʀᴛʜVᴀᴅᴇʀ

@TheWanderer huh??

TNB

guess not lol

DᴀʀᴛʜVᴀᴅᴇʀ

I am an all powerful mod

oh great, another @ThomasWard

:p

maybe you are @ThomasWard c_C

@Seth how's this one:

I keep thinking that stick in the bottom left is a watermark..

Better, still really soft though.

I don't think that's something you can fix in post.

2:30 AM

soft?

like NR?

this is my V20 btw, not my DSLR

@TheWanderer I guess

it just looks like all the colors kind of bleed near the center

well it is just the JPG the phone produced

what lighting conditions was this taken in?

clouds

@TheWanderer ah. I thought you shot RAW and were processing.

2:33 AM

nope

@TheWanderer I wonder if you bumped the exposure up a notch..

half a stop maybe

that's why I shared this, because it's completely unedited

idk, phone cameras don't handle red well

nope

@TheWanderer I mean, I think it's still a great photo

2:35 AM

ooh

(obviously edited)

3:02 AM

Aww yeah

@LandonZeKepitelOfGreytBritn so ubuntu delivers updates through update channels. Each of those checkboxes in the "Updates" tab of software-properties-gtk controls one. They're coded release-channel so in this case xenial is the release and updates and security were the channels we needed. I thought these were enabled by default but I guess I was wrong. You can learn more about update channels here.

When you tried to install teamviewer apt knew some of those packages existed, but it didn't know where to find them, hence the problem.

Kaz Wolfe

3:26 AM

yet another cool problem.

can't ping out or anything

my system is now deciding to stop connecting to new websites after a while... old connections work fine, but new things just... refuse to work

@Seth jealousy intensifies

4:18 AM

Wow, first time I've been seriously dissatisfied with an Android update.

If it wasn't such a pain to do I might go back to nougat.

4:45 AM

Any problems?

Hello ! :) Is there anybody around here ? Well, most probably @ByteCommander seems to be right -> chat.stackexchange.com/transcript/message/39428457#39428457 Looks as if Smokey takes over ... :(

Q: Multichain xx -daemon - then what happens on reboot?

@NathanOsman No problems per se, but they made several bad choices IMO. e.g. apps can no longer draw over system UI, which makes sense, except they pulled nightlight so there's no way to change the color temperature, meaning the lockscreen, notification bar and shade, as well as the volume controls, etc are all extremely bright at night. Then there's now a persistent system notification anytime an app is running in the background. No way to dismiss it.

I always have at least 1 app running in the background.

Oh and they made the notification shade completely white, which compounds the nighttime issue.

Hey @Seth ! :) Nice to see you ! :) How are you doing ?

The blockchain program Multichain has a command: multichaind chainname -daemon https://www.multichain.com/getting-started/ My question is whether this will survive a reboot (specifically on Ubuntu, but more in general just trying to learn). In other words, do we need to create a script to...

I have a postfix server running on an EC2 instance. I want to forward all email, via SES, to my personal inbox.

5:16 PM

Anyone have thoughts on Lenovo?

no more Suprfish, and they're the only well-known name I trust anymore by POE

Does anyone know if you could install Ubuntu on this?

I get the feeling ChromeOS tries pretty hard to prevent that sort of thing.

16GB SSD?

literally no room lol

That's enough for a bare-bones install.

why do you need it

5:19 PM

This would be used as a thin client.

Documents and whatnot would be accessed over SMB.

Crouton looks like a hassle

just get one of those cheap $150 desktops

It needs to be portable.

And I don't mean this:

xD

how do you feel about an old-ish HP Pavilion?

Erm... maybe not.

6:01 PM

well that's dumb

MSI screwed the hinges into the soft plastic back of the screen

Someday, some big historical event will happen during the DST changeover, and all the tick-tock articles chronicling how it unfolded will have to include a really annoying explanation next to their timelines.

:-D

@Seth CS for Prostar is super responsive. I sent them a message on Amazon to see if I could get a version with 16GB RAM and a 128GB SSD, and they got back to me in like 15 minutes

oooooh

YouTube has an actual dark mode now

edwinksl

orly

ye

8:31 PM

it's had that for a while

I only got the new layout today

Google (and other companies) has been known to roll out to new features to parts of its user first, leaving the rest out, as a sort of public beta test.

I've had a sort-of-new layout for a while, that was sort of halfway between old and new

8:56 PM

@TheWanderer and the Android app has been ruined.

It's all white now.

And ugly.

the YT app looks like it's from 2001

what did they think they were doing?

"material design"

it's not Material

But they think it is.

GNATSSS

9:21 PM

@Seth thank you very much for your answer! Clarifies quite a lot

@TheWanderer I've had it for months and I keep clicking "I don't like the new design" :P

and then it goes away for ~1 week

@NathanOsman and MS ruined the Skype app

Yes.

9:39 PM

Skype’s interview feature pairs video calls with a code editor

Wat

That would be so stressful for the interviewee

Yup others agree --^

@AndroidDev: I think it has some low-stress use cases, e. g. "spot the mistakes in and fix this code fragment" accompanied by oral or written explanation of what's wrong and why and how it can be fixed.

@DavidFoerster hmm yeah fair point

…basically just-in-time code review.

Hmm, speaking of JIT... I wonder if Google has fixed most of the bugs in ART yet

I would hope so, seeing as we're now 4 releases since it's introduction

(Well technically it was introduced in KK but you had to enable it in Dev Options)

I could think of some egghead managers who think "but we want to see how the candidates work under stress". Dude, if your software developers need to work under stress you're not qualified to lead them.

9:46 PM

lol

true though

… or your business has poor work conditions which will inevitably lead to poor products.

and spaghetti code

yum, spaghetti...

@DavidFoerster that's r/a

@ByteCommander What does "r/a" mean?

rude/abusive

the other red flag

Oh, right. Sorry.

@SmokeDetector Sorry to you too, Smokey.

Hm?

@ByteCommander: I think my mistaken spam flag made Smokey pick it up. Afaik it doesn't post notices about r/a flags.

it does

and I reported it

it only picks up your flags if you have the userscript installed though

10:33 PM

Oh.

Crazy Dave

@TheWanderer: Pot head.

well?

guess he just had no tinfoil around and took the next best thing

to be fair, he lives in a world where zombies attack from either yard in rows and then you use plants to kill them

how do I define a variable in BASH?

oh just has to be at the beginning lol

guys

is there some regex I could use in BASH to do this:

find the line that contains:

# LG RCT(Rooting Check Tool)

then comment every line until it hits an empty line

ie:

...

# LG RCT(Rooting Check Tool)
#service rctd /sbin/rctd
#    class late_start
#    user root
#    group root
#    seclabel u:r:rctd:s0

...

there's text above and below, but I need to make sure just that block is commented or removed

10:51 PM

@TheWanderer: sed -e '/^# LG RCT(Rooting Check Tool)$/,/^$/s/^/#/'

wow, pretty easy

how can adapt that to edit a file though?

(name is init.lge.rc)

Do you mean, edit the file in-place?

sure

cat?

and >?

Use sed's -i option.

thanks

so sed -ie '/^# LG RCT(Rooting Check Tool)$/,/^$/s/^/#/' init.lge.rc

10:54 PM

No, -i accepts an optional argument for the file name suffix of the back-up file. You need to use sed -i -e ... if you want no backup file.

With sed -ie ... you get a back-up file with the suffix e.

oh lol

hmm is it possible not to comment the blank line? doesn't really matter

Yes, I'm working on that already.^^

oh

I can also prevent "double" comments.

oh nice

11:00 PM

I'm testing with paste.ubuntu.com/25434952

The sed command /^# LG RCT(Rooting Check Tool)$/,/^$/{/^$#\|$$/!s/^/#/} works on that and results in output like in your example.

nice

You can tell that it's not just line noise because the parentheses and braces are properly grouped. ;-D

lel

oh

what's the if statement to check if the command returned an error?

specifically file-not-found

If I run sed on a non-existing file it exits with a non-zero status code (2 to be precise).

no I need it to check in a cp command not sed

11:12 PM

There are multiple ways to check for (non-)zero exit codes in shell scripts.

because this is all inside an Android kernel, and if it doesn't exist, then there's an issue lol

just need a simple one

Same. Most commands will return non-zero status codes when they fail.

You're writing shell script to be executed from within an operating system kernel? Ó.Ò

no

it's extracting LG's kernel, modifying some stuff and repacking

so I need to make sure the boot.img is actually there

To test command exit codes: command lists, conditional constructs, the ? built-in parameter

You may also find the -e option of the set built-in command useful.

I just used if [ ! -f boot.img]

11:45 PM

how can I check to see if the output of a command contains a certain string, using an if block?

Remember to update the firmware on your pacemaker, folks.

how do I do the || condition in BASH?

Isn't that how you do it?

i dunno

I have this echo 'adb get-state' | grep -q "error"

but I need grep to match error or unknown

That's a pipe.

Ah.

11:56 PM

I know it's a pipe lol

phoneman

Try using a regular expression in grep.

error|unknown

That will match either.

ah

It's just hard to type. Period.

@TheWanderer no

it doesn't work then
