wondering if I have some light type of OCD.. I just spent ~30 minutes replacing every empty HTML tag because I was closing them without an space before the slash

like <br/> instead of <br />, and I read somewhere that the xhtml1 spec states there should be a space before the slash (not that a single relevant browser cares about it..)

Android Dev

01:31

@IanC why didn't you do a find and replace "/>" with " />"?

IanC

@AndroidDev I used %s/$\S+$\/>/\1 \/>/gc, because some tags had the space already, so a simple replace would end up with double spaces

Android Dev

I'm no good with regexes, so I would've done a 2nd find and replace double spaces with single :P

IanC

lol, guess that would work too

that regexp isn't that tricky: everything inside $ and $ gets saved in a pattern, \S means any character that is non whitespace, + means happens once or more, \/> is just the "/>", but I had to escape the slash

then \1 is the saved pattern, plus a space, plus the "/>", and gc for global replace and ask for confirmation first

basically matches any non whitespace characters followed by "/>" and replace them with the same non whitespace characters, plus a space and "/>"

I'm not very good at Regexps too, had to review some stuff to make this one

And they sent a survey for developers to get feedback, so I thought "ah, I'll tell them that they shouldn't do that."

I answered the first question and the survey ended "sorry, you do not qualify for this survey."

I mean - do you want the feedback or not, Amazon?

I'm seeing NXDOMAIN - doesn't that mean it isn't an active domain name?

First bounty you offer on another person's question. \o/ If someone is interested in 250 extra, here you go!

Hello and good afternoon :)

@cl-netbox Hi cl!

cl-netbox

@dessert Hi :) How are you doing today ?

dessert

@cl-netbox Very good, and you?

vidarlo

I'm really struggling to understand why my flag as not an answer was not accepted for askubuntu.com/questions/1005133/… :D

cl-netbox

@dessert That's nice - same here ... I have tested libguestfs-tools which lets me modify virtual disks when the VMs are shutdown ... works perfectly. :)

dessert

@vidarlo It's a solution after all…

vidarlo

15:36

@dessert barely... but yeah.

dessert

poor answers are still answers, but a downvote may be appropriate

I stumbled across this question today and am eager to receive a truly good answer, so I started a bounty – let's see what that does.

vidarlo

I guess it's partially hardware dependent as well?

Rinzwind

boxy!

dessert

@vidarlo It is, I included that in the bounty description

@vidarlo What wrong about google's DNS server? skimming?

vidarlo

all computers do have a hardware switch in the jack port, but it may simply be a signal to software, or it may actually change hardware configuration of sound card as well

dessert

15:43

@vidarlo so that is what one should determine first I suppose, but how?

vidarlo

probably look at the kernel module

Q: white space in ZFS command line

I have found that white space seems to be significant in ZFS commands, but only apparently under some conditions.. For example, both of the following commands work: root@grandidier:~# zfs list -t snap -r tank/srv NAME USED AVAIL REFER MOUNTPOINT tank/srv@initial 4.22G ...

wtf oO

Is this a zfs bug? It's certainly not an issue with bash command substitution – or is it?

I think I am done helping people asking about crypto currency mining scripts. It honestly feels like to me that they are not willing to learn the scripting process at all and are looking to us to write it all for them.

Why do I keep getting more and more upgoats on this post recently? O_o

maybe because more and more people are screwing with secure boot?

Terrance

18:43

Could be! I upgoated that one a while ago. =)

@AndroidDev I wouldn't doubt it if they were. The other day someone got locked out of their Lenovo and had to reset it, then had to change the Secure Boot. So, yes, I can see that as more and more now. =)

There's only one review.

So I'm suspicious. I was expecting to spend at least $90-$100.
