@SergiyKolodyazhnyy Sorry I missed yesterdays ping. Not sure why I didn't get notified...

Sergiy Kolodyazhnyy

@WinEunuuchs2Unix If you're not in chat for several days you don't get notified. I don't know the time limit though

WinEunuuchs2Unix

makes sense. I haven't been here in weeks if not months

how you been doing lately?

Sergiy Kolodyazhnyy

Alive. Busy with school projects. Caffeinated and typically sleep deprived

How you've been ?

WinEunuuchs2Unix

you're about 8 years through your 4 year course now?

I've been doing good up until a week ago where I got passed up for a promotion at work.

So now I'm looking for better work :)

Sergiy Kolodyazhnyy

@WinEunuuchs2Unix Basically, yes. I started in fall of 2009

WinEunuuchs2Unix

12:29 AM

oh well rome wasn't built in a day and you have tons of extra-curricular activiities

Sergiy Kolodyazhnyy

yeah, probably more than necessary

WinEunuuchs2Unix

I think you are enjoying life on the internet and developing your projects. That's what counts I think for you.

I scrolled up and found the link:

@JacobVlijm askubuntu.com/q/1085980/…
@WinsEunuuuch2Unix cc ^
I'd handle that question but sadly no time lately.

Sergiy Kolodyazhnyy

yup, that

WinEunuuchs2Unix

The question sounds familiar and I wonder if there are dups?

In any respect I read somewhere that xrandr can do monitor by monitor separate scaling unlike the windowing managers do it now where it's "all for one and one for all".

Sergiy Kolodyazhnyy

If there are - great. If not - it's easy to implement. Infinite while loop, parse output of xprop -root comma d to find out current workspace, and run xrandr -output MonitorName -mode 12345x54321

WinEunuuchs2Unix

12:35 AM

I'm not a fan of infinite loops. I finally got on your dbus bandwagon and in last project watch tor dbus --system for changes to screens and then invoke my own script(s).

I was thinking of buying a 4K TV to replace my secondary TV (FHD) so the OP's question would come in handy for myself and many others.

Sergiy Kolodyazhnyy

:) Yay, someone finally recognized my dbus ways

Eh, I've dual monitors at home, one is 1449x900 or something like that, VGA, and the other is also VGA but connected via vga/hdmi connector , and something like 1689x1230 I don't remember exact numbers.

Both monitors from Goodwill. I'm cheap when it comes to monitors :)

WinEunuuchs2Unix

I have 17" laptop display and two HDMI TV's (55" & 32") all are 1920x1080 to make life simple.

But the 32" is very very old so I was thinking of getting 40" 4K Sony on Black Friday. When is that in the states anyway? (they mimic sales in Canada too now).

Sergiy Kolodyazhnyy

Black Friday is the first Friday after Thanksgiving, which is sometime in 20s of November. I need to Google that.

November 23 this year

I'll probably be shopping for sensors, raspberry pi, and whatever else. I actually have two, but pi zero is not supported by OpenWRT.

Or I might go with another board.

WinEunuuchs2Unix

Haven't had serious urges for Pi yet but they sure look like fun. My other wish list is a 16 GB RAM stick so Android Studio doesn't bog down my system. Want to make my first phone program.

Sergiy Kolodyazhnyy

Oh wow

I've been learning couple new tricks too. I've sort of dabbed into kernel module development. If it works out, maybe for my senior project I could have a kernel module that's gonna simplify a few operations

But if not - I'll just bitbang everything through userspace

WinEunuuchs2Unix

12:56 AM

My first Linux project was a kernel module it was fun. Remember when you recommended SQLite for importing CSV file? I've been reading up on SQLite3 last few days and it sounds really cool.

Sergiy Kolodyazhnyy

Oh, awesome ! Yeah, SQLite is fun. We also been studying MySQL in class but installing it is pain

I plan to move some of my projects later from json config files to sqlite

gonna be actually more professional

WinEunuuchs2Unix

MySQL and Postgres are more popular for larger websites for sure. But I'm looking at small website stuff, plus phones use SQLite too.

Sergiy Kolodyazhnyy

Yes, sqlite is definitely the way to go for Android development

WinEunuuchs2Unix

Plus the browsers use SQLite too :)

Sergiy Kolodyazhnyy

Yup. In general anywhere you need a database but not need a full db server - that's good

A Berkeley db is also an option if you do Python, but it's just key value pairs db, so no tables or aggregate functions

WinEunuuchs2Unix

1:02 AM

It'll take me a long time to learn SQL but I've been meaning to learn it since the mid 1980s and I know I'll enjoy it when I'm done.

Sergiy Kolodyazhnyy

SQL itself is easy. It's the gluing basics together that takes time, and also managing relationship between different tables

Seth

@WinEunuuchs2Unix It's not very hard to pick up.

WinEunuuchs2Unix

@Seth Hey long time no see. How is WA? Yeah with all the SQL tables embedded in Android and FIreFox I'll have lots of fun browsing them :)

Which reminds me @SergiyKolodyazhnyy how is IL?

Seth

I could probably send you my SQL homework from when I took that class, if you want.

@WinEunuuchs2Unix hi! WA is as great as ever. Overcast, depressing, cold.. I love it :P

WinEunuuchs2Unix

@Seth Well at least you don't get the freezing cold and snow like we do in AB. Thanks for the offer on SQL homework I might take you up on that around Christmas time. I have 10 days off for learning.

Seth

1:08 AM

@WinEunuuchs2Unix Fair. I don't much like snow. Alright! Just shoot me a message or email if/when you want it :)

WinEunuuchs2Unix

@Seth Thanks! My first project will be Android Studio though and only Google knows how long that will take me :)

Aaron Hall

1:42 AM

Helping my cousin install over the phone, do we need to connect wifi? He doesn't remember the password, but he says he's plugged in with an ethernet cable. Can we ignore the wifi part?

Seth

@AaronHall yes

(assuming this is an ubuntu installation)

Aaron Hall

it is...

looks like he figured out his password now...

Seth

yeah you don't need internet. I always skip that step myself.

Aaron Hall

sorry

Seth

No worries.

Aaron Hall

1:49 AM

is there a page-by-page tutorial on installation that I can look at while he's doing this?

think I found it: tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-desktop#4

Sergiy Kolodyazhnyy

@WinEunuuchs2Unix CO actually. So far warm.

WinEunuuchs2Unix

Colorado? That's close to Me and Seth. For some reason I thought you were in Illinois

Aaron Hall

I want to try to preserve his windows partition for his files, so I'm selecting "something else" on allocate drive space page...

WinEunuuchs2Unix

@AaronHall Before something else you have to boot in Windows and shrink that partition size by at least 20 GB to install Ubuntu.

Aaron Hall

@WinEunuuchs2Unix his windows is broken and won't even boot.

WinEunuuchs2Unix

1:56 AM

In that case I would boot with the Live USB and try to shrink the Windows partition with it before installing. Not sure what utilities you need for that though.

Aaron Hall

Looks like he can't read his Windows partition...

WinEunuuchs2Unix

@AaronHall I guess you kind of can do it since it's broken already: askubuntu.com/questions/468508/…

Aaron Hall

Nah, it looks like he's going to have to overwrite his Windows partition, am I right?

WinEunuuchs2Unix

No.... Shrink the partition first by 20 GB or more and then install Ubuntu in the empty space.

Aaron Hall

It says it doesn't know the type and under "used" it says "unknown" and that's the only partition with 20+GB... look at the image.

at this point I think he should just back out and do a regular install

WinEunuuchs2Unix

2:08 AM

There's already a Linux partition of 30MB created?

Aaron Hall

Maybe he tried to install earlier and got grub on it somehow.

WinEunuuchs2Unix

It looks like a 1 TB drive so you should be able to srhink Windows partition by a lot. But yeah a fresh install wouldn't hurt I guess. Most people have garbage in Windows anyway :)

Aaron Hall

He's had some tech guys on the phone doing stuff too. We disabled secure boot...

@WinEunuuchs2Unix I don't see how he can "shrink windows" when Ubuntu can't read it.

How do we back out to the regular install from here?

I'm just going to have him to the full install.

WinEunuuchs2Unix

It can still shrink the Windows partition size without reading it. You could install testdisk though and it might repair the parition for him.

Aaron Hall

I... am frustrated with him - it's been a week of me telling him to install Ubuntu, and I just want it done...

Can I back up a page?

WinEunuuchs2Unix

2:13 AM

Sure. Use a photocopier ... lol

Aaron Hall

what does revert do?

WinEunuuchs2Unix

revert undoes the last action queued up I think.

Nothing happens until you applied the queued actions anyway.

Aaron Hall

looks like there's a back button hidden, so he clicked it...

So do we do LVM or "erase disk"?

we're looking at this page now: tutorials.ubuntu.com/tutorial/tutorial-install-ubuntu-desktop#5

I've never done LVM...

WinEunuuchs2Unix

I wouldn't use LVM. Adds complication.

ThatRandomGuy

2:30 AM

Is there a good reason as to why I had to earn the privilege to get into chat? Can't they just allow anyone to get in and simply report/expel trouble-makers?

Aaron Hall

@ThatRandomGuy it's the internet - too much trouble.

ThatRandomGuy

2:46 AM

It seems weird that they'd make this kind of feature exclusive. Granted I didn't do much of anything to get the notification, I don't see why they need to close this off by default. This probably isn't the ideal place to seek answers but it's kind of for that reason why they should open this up to everyone. Take this room for example: there's hardly anyone in here. It's like they've paid for something in full but only utilized a small portion of what they paid for—the mind boggles.

Seth

Don't use LVM

Aaron Hall

ok, no LVM

he took out the thumb drive when it told him to, and he's rebooting now

Seth

LVM is one of those things that, if you don't know what it is or what you're doing, you don't touch.

@AaronHall awesome

Aaron Hall

@ThatRandomGuy chat is ancillary, the main point is Q&A sites. chat just lets us have a "third place" or side channel for conversation - mostly about the Q&A.

Or subjects that relate to the Q&A.

Or tangential stuff.

Or whatever else...

Aaron Hall

3:07 AM

@WinEunuuchs2Unix thanks for the help!

@Seth thanks for the help!

he's got it booted and installed Chrome and should be installing Anaconda...

Seth

@AaronHall np!

Aaron Hall

(we're off the phone so he's on his own until tomorrow...)

He's been trying to use a thumbdrive for extra "RAM"/memory (swap?) and I'm trying to discourage him from doing that. He has 8 GB system memory anyways. thoughts?

Seth

3:58 AM

@AaronHall 8GB should be plenty for most casual use

I have a few people using thumbdrives as extra SWAP but they have 2GB and 4GB respectively. You'll know when you need it. Performance degrades to an almost complete standstill and the SWAP/pagefile will be full.

Lots of disk throbbing.
