I'm thinking I should commit more..

Those are all HTML5 attributes.

you're right, it's not Microsoft's fault (this time)

I head of Number Polyfill, maybe I can use it for backwards compatibility

or I can just ignore IE10-

Nathan Osman

Yeah, I'd try to support IE10 at a minimum.

Q: Does the title of this question capture OP's question well enough?

OK, so we have this HNQ, which gathered quite a lot of attention, snarky comments, and a small edit war between me and another user about the title of the question . I've edited the answer to match the body of the question. Issue is that it can be viewed from different points of view: is OP aski...

Sergiy Kolodyazhnyy

Ah, here it is. Meta took its sweet time

David Foerster

Imho all edits after askubuntu.com/revisions/986395/2 were either superfluous or harmful to convey the intention of the question author as far as I understand it.

Anyone got any idea of wtf is happening here, getting the error `E: Unable to correct problems, you have held broken packages.
`

Everyone says install aptitude and use it

I don't want to install aptitude. I want to fix the problem

where do I go looking, I have no held packages.

Nathan Osman

05:48

Hi @EvanCarroll.

I haven't seen you in a really long time.

Evan Carroll

How bad were the withdrawals, hope all is fine? Not all weather it so well.

Nathan Osman

In regards to the error... you can try running this to find out more about what apt thinks is the problem:

sudo apt-get install -f

People are likely suggesting aptitude since it is more verbose than apt-get.

Evan Carroll

doesn't do anything. =(

Nathan Osman

Hmm...

Evan Carroll

I like to understand my package system. I'd rather know why than have magic sauce.

Nathan Osman

05:52

Right - but I meant that aptitude prints more descriptive error messages.

I'm actually using Arch right now, not Ubuntu so I can't really check any of the commands I'd give you :(

Evan Carroll

Yea, this will be my last year on Ubuntu

New years resolution time coming up

I just don't want to go out defeated. That's no fun.

Going to migrate to Qubes.

Journeyman Geek

hm

askubuntu.com/a/363244/17681 was this suggested?

(I'm currently on fedora on the desktop, and my ubuntu server's remarkably vanilla and unbroken)

Evan Carroll

Yep, I already put the results up there

Ubuntu isn't doing anything interesting, and it's not particularly polished anymore.

Nathan Osman

Qubes is pretty cool from what I hear.

Lemme know how it goes.

Evan Carroll

Will do, at least it's exciting. And, though based on security, I like that they're making radical changes to achieve their goal.

They migrated from KDE to Enlightenment (which is my preferred DM).

So it's really just a jump from dpkg to rpm, and I've used red hat based distros before so it shouldn't be that bad.

Nathan Osman

06:04

I use Enlightenment on a low-cost netbook and I love how few resources it uses.

Evan Carroll

Yep, it's great all around.

I'm running Xubuntu now

and have been for a very long time.

@JourneymanGeek I run LXDE on my desktop.

This question is loosely related to one of my previous ones.

@Fabby I think you just need to alter debkernels to include not only $previous_version, but also $pre-previous_version and $pre-pre-previous_version, which can be defined as pre-previous_version="$(echo "$debverlist" | sed -n 3p)" and pre-pre-previous_version="$(echo "$debverlist" | sed -n 4p)" respectively.

@Fabby if you format you code by indenting it, html tags like <b> are not interpreted, if you use <pre><code> instead <b> works as expected – I suppose you wanted to print those lines bold?

Fabby

Yeah, and they did...

yours just came in a box whereas mine just came in courier with a gray background.

@Fabby Wait, are we talking about the second revision here?

Fabby

yup.

can't see what you did there...

I knew I had to use <pre><code>

but what did you change between rev1 and 2?

Ah!!!

@Fabby I just changed </pre/ to </pre> there.

@Fabby “on cue” – one can really learn English from you!

on-cue would be British English; but I've noticed Amrerican English drops a lot of the dashes.

(As I live in Germany; but am not German, I completely misinterpreted the arm joke)

@Fabby Interesting, what did you think I meant?

Fabby

I thought you were not German, maybe knew from some other people I live in Germany, assume I was German and that it might be offensive to me.

I was born in a country where the Nazi-salute can be insulting, but is not forbidden by law...

dessert

from a linguistical point of view, English and German are just two West Germanic dialects – they are not really different enough to count as separate languages, although the distinction between a dialect and a language is not an easy one.

Fabby

There are multiple opinions on what consitutes a language.

David Foerster

Aren't space operas pretty much fantasy, just set in a future-y universe?

I mean, Jedi and Sith are nothing short of space wizards and the story telling of the original Star Wars trilogy resembles that of fairy tales.

It was and still is the same with media that incite hate, glorify anti-constitutional ideologies or carry symbols of groups with such ideologies (including most Nazi and Wehrmacht "memorabilia").

The law doesn't care if you keep that stuff at home or even show it to people in a private setting. Just don't pass it around. Exceptions for criminal prosecution, teaching, research and art exist of course.

My grandfather was pressured to join and did join Hitlerjugend in his mid-teens before he was drafted into the Wehrmacht as a young adult.

Fabby

Yup: shit happens...

The most interesting piece of literature I ever read (was forced to read in school) was the diary of a girl in the Bund Deutscher Mädel and it shows how the entire society was corrupted bit by small bit and if you weµre a follower and did not resist, you just slid into Nazi belief.

(one of the things that changed my life around: from that moment on, I became extremely sceptical of everything government and media)

David Foerster

He was Sudeten German living in Czechoslovakia who harboured much support for Hitler and his plans to "bring Germans [living in other European nations] back into the Reich" because they were generally underprivileged.

("who" = his ethnic group, not him specifically)

As far as I know he didn't think much of all that "hysteria" but, at that age, had no strong opinion or conviction to the contrary as did his parents.
