Q: Is this legal? Someone earned a bounty answering his question

Look at this post How to efficiently partition a single Windows-Ubuntu dual boot disk? I'm just wondering, what happened here… Could I make the same?

Grr, I hate waking up drunk.

@DavidFoerster Nothing wrong with waking up drunk, just take the bus - don't drive or ride a bicycle. The latter two will end badly for everyone.

hi. I have every snap mounted twice for each revision installed. ISn't that a bug ?

every revision of snaps are mounted

Any idea how I could pinpoint what is freezing my mouse randomly of my upgraded 17.10->18.04 ubuntu ? Works fine on a fresh 18.04. I don't want to reinstall again

David Foerster

16:39

@RobotHumans Yes, there's something wrong with waking up drunk but too awake to fall asleep again if I had enough time to sleep for a few more hours. Can't rest or be productive, just pass the time until I'm sober enough for simple tasks. ;-(

Tachtaeni

19:12

Hey! Got any suggestions for a TTY-based (for no distractions and longer battery life) writer with prose in mind? If it likes Markdown that's even better.

vim is not for prose at all, if i'm not mistaken

at all

and i don't like fat, obese word processors either, even if they are FOSS!

dessert

@Tachtaeni Why should vim not be suitable?

Zanna

I write all kinds of rubbish in Vim

dessert

googling “vim prose” yields some very interesting results on how to use vim best this way

Zanna

but Emacs does that thing where you press to left arrow at the start of a line and it goes to the end of the previous line afaik, which is helpful

Tachtaeni

i was born in 2001 dont expect me to not go "WTF?!" at vim easily. lol

terdon

19:22

I wrote my entire PhD thesis, so essentially a book, using LaTeX and emacs.

Tachtaeni

I'm sure you've all got something to say against that statement tho

Zanna

I mean, you can do the same thing in Vim by pressing esc j A which is obviously er... more exciting

terdon

@Zanna Wait, vim doesn't? I thought all editors do that.

Tachtaeni

When you first run vim it grabs hold of you like an icy thing that grabs things and doesn't let you go

As in it's not easy to quit if you're at the bottom of the learning curve.

Zanna

@Tachtaeni the thing about Vim is that you can learn about 3 things, and then you can just boast about how you know Vim. You can even impress people by exiting from it as a party trick.

Tachtaeni

19:24

Anyway, I'll consider vim i suppose, but what else is there?

Zanna

@terdon no! it silently goes "nope, we're at the start of the line, we can't go any further"

terdon

Huh

Even SE's editor does that. I always knew vim was useless :P

Zanna

like I said, you only have to press esc j A! obvious, right?

terdon

@Tachtaeni emacs

Tachtaeni

Is emacs vs vim like rem vs ram or amd vs intel?

terdon

19:27

@Zanna I will not be drawn into a my-keyboard-shortcuts-are-more-intuitive-than-yours fight. I use emacs, after all. No sense in joining battles I can't win.

Editor war is the common name for the rivalry between users of the Emacs and vi (usually Vim) text editors. The rivalry has become a lasting part of hacker culture and the free software community. The Emacs vs vi debate was one of the original "holy wars" conducted on Usenet groups, with many flame wars fought between those insisting that their editor of choice is the paragon of editing perfection, and insulting the other, since at least 1985. Related battles have been fought over operating systems, programming languages, version control systems, and even source code indent style. Notably, unlike...

Zanna

haha I am just a popcorn-eater in this war

terdon

Real programmers set the universal constants at the start such that the universe evolves to contain the disk with the data they want.

Those two sort of sum it all up.

Tachtaeni

cat??

Isn't cat just... the command that lets you see the contents of a file?!

terdon

That's not an editor. It's a small to medium sized mammal.

Tachtaeni

lol

terdon

19:28

It is also a command that does nothing else but copy its input to its output. It doesnt modify it, so it isn't something you can use to edit.

Zanna

$ cat << EOF
> hi
> I'm
> writing
> a file!
> EOF
hi
I'm
writing
a file!

terdon

Unless you do something like that, yes. But that's silly :P

Tachtaeni

if i know anything about bash then...
echo FLESH | cat | cat | cat would just echo FLESH?

Zanna

@terdon isn't that why it's in a comic?

terdon

Indeed

Zanna

19:30

$ echo VEGGIES | cat | cat | cat
VEGGIES

terdon

Although the main point of that comic (which would have been evident to you were you not handicapped by your choice of editor) is that emacs is best, emacs is best, only a fool would use all the rest!

dessert

@Zanna or just Ctrl+O j to stay in insert mode

Zanna

how will that get me to the end of the previous line?

Tachtaeni

hackernoon.com/vim-for-writers-ee15d2a8f512 has intrigued me

I shall use vimtutor in a tty.

dessert

wins

terdon

19:33

@Zanna It won't, but at least you'll have a nice glass of freshly squeezed OJ.

Zanna

lol

Tachtaeni

doesn't mean i'm gonna dress up in an army uniform and use one of those... physical vim tool things

Zanna

lost in Vim? never mind, just relax and have a drink

Tachtaeni

vim.org/images/vim_drill_small.JPG seriously how is that a text editor

Zanna

@terdon you're right, I'm too busy trying to save this file to get any jokes

dessert

19:34

@Zanna sorry, i meant C-o k

Zanna

but if I press k in insert mode, I get a k...

dessert

@terdon I recently learned it's actually nano: askubuntu.com/questions/1030561/…

@Zanna that's why you switch to normal mode just for one command with C-o first

terdon

@dessert snort

Zanna

@dessert but I mean, we are not getting to the end of the line... (ps earlier I said we should press esc j A, but when I said j I meant k) <-- see, lost...

dessert

@Zanna and I copied this j from you, yes :D

Zanna

19:41

my bad, sorry

dessert

@Zanna true, not the end of the line – who wants to get there anyway, and why?

Zanna

because in other text editors, such as Emacs, you can just press the left arrow

Vim doesn't seem to be able to think about the end of one line as coming directly before the beginning of another

I mean, when I'm writing prose, I often want to go to the end of the previous line

dessert

well if you ask muru he surely writes some function for you that tests for the cursor position and does either h or k $… can't be so difficult, can it?

Zanna

I don't have any problem with typing esc k A - I'm used to it now. But Tachtaeni was talking about writing prose with Vim

but yeah, I'm sure muru can make Vim do any kind of magic trick you like

@dessert I think karel was joking :)

dessert

@Zanna I can never tell ;D

Zanna

19:48

this task seems hard - I couldn't figure out how to do it, I wanted to get some other stuff done, so I left it. But I feel sorry for OP. The info she wants isn't just lying there in the html. Alas I'm clueless about this topic

terdon

@Zanna You do not do it by trying to parse the website. That way lies madness. This is an EMBL resource, so they will provide ways of getting this data. But not this way.

Zanna

yeah, that's what it seemed like to me... query the database!

(PS does anyone know any resources to help me learn to write SQL queries (for SEDE)?)

terdon

@Zanna Yes, Monica wrote a great tutorial for SEDE. It's linked to somewhere on the SEDE page.

data.stackexchange.com/tutorial

Zanna

oh thanks! I thought I had read this one... maybe I just skimmed it looking for what I needed a few times... I don't think I have actually read it properly

terdon

It also gives you the basics of SQL (or whatever flavor SQL they have there) queries.

Zanna

20:05

maybe I will find the problem with the query I'm working on thanks to this :)

Q: Ubuntu 18.04 Mouse Pointer Blinks and disappears on one screen after setting HiDPI scaling with xrandr

I use Ubuntu 18.04, on Dell XPS 15. There is a huge difference in the resolution of my screens, so when I plugged external monitors, either everything was too big on external monitors or everything was so small on laptop monitor. I used xrandr to setup the scaling as follows: xrandr --output eD...

Byte Commander

20:24

@Zanna well, it could be done with a stack of Python+Selenium+PhantomJS or s, but.... as terdon said, it's probably not worth the effort

Zanna

:)

Byte Commander

problem is that diagram is created using javascript

and the ID in the link URL is nowhere else other than this graphic

dessert

@Zanna let c=getcurpos() | if (c[2] == 1) | execute "normal k$" | else | execute "normal h" | endif

got it, that's the whole function – gets the cursor position, tests if it's in column 1 and executes the commands that move the cursor

it's as easy as that with vim :)

Zanna

:) impressed

Zanna

20:55

the problem with my query seems to be that the table doesn't have the data it says it has :/
