Q: Install Ubuntu live USB to USB or computer

ahum12I have a live USB with Ubuntu 14.04 with things I have installed and deleted, and preferences that I've changed on it, and am wondering if it's possible to install Ubuntu onto either another USB, or onto a computer and have it keep everything I've changed.

ubuntu live-usb

There's something fishy about this page. Xorg CPU usage jumps every time I bring it up in Firefox.
Doesn't happen in Chrome.
 
hbdgaf
hbdgaf
Are you sure? It looks pretty benign. Pre-fetches if they pre-render and there's lot's of styling/re-sizing in hidden windows would make sense.
Do you get significantly faster page-loads from firefox? Or do you still wait when you navigate through a couple of links for split-seconds?
Didn't try it in FF. FF isn't event installed. I'm a chromium guy.
 
Nathan Osman
Nathan Osman
:)
I've got everything from Chromium to Dillo installed :P
I have IE6 and IE11 installed in various VMs.

Just trying to make a jump to a logical reason. That's all I've got.

@mateo What's the address?
I'll take a screenshot for you.

I really need to update it and do a blog or something...

but hey, I was doing the flat metro colors back before it was popular ;)
@NathanOsman close...
so it "works", there are a few things off huh
 
Nathan Osman

It's a lot better than any of my websites look on IE6.

@NathanOsman thanks, that was interesting

@Mateo - finally got around to watching guardians of the galaxy. bit of both was a great closing line.
also, you could always take the grid for a spin thegrid.io/…
 
Mateo
Mateo
@hbdgaf awesome movie
 
hbdgaf
hbdgaf
yes, i enjoyed it more than i thought i would
 
Mateo
Mateo
I'm glad they stuck to a very strong back-story plot going on through it
 
hbdgaf
hbdgaf
I just like that they stuck to character traits instead of having a "spy" among them as is typical
 
Mateo
Mateo
@hbdgaf hm, a website that designs itself

2:45 AM
It's interesting to say the least.
Does anyone know of an algorithm to advance a square from a corner to an opposite corner one cooridinate at a time? Example:
[0,0], [0,1], [1,0], [1,1], [0.2], [2,0], [1,2], [2,1], [2,2] as a 3x3 example?
 
Nathan Osman
Nathan Osman
I think I'm going to give multiseat a try.
 
hbdgaf
hbdgaf
It seems easy enough to write, now that I wrote it down as sample coordinates. Nevermind...
 
Nathan Osman
Nathan Osman
I've got two 1920x1080 monitors, three USB keyboards, and two mice.
 
hbdgaf
hbdgaf
@NathanOsman multiseat seems interesting.
 
Nathan Osman
Nathan Osman
Should be enough.
The only thing I really lack is desk space :P
 
Mateo
Mateo
2:48 AM
do you have multiple cards?
 
hbdgaf
hbdgaf
I want more screen real-estate, but I'm debating between that and screens/monitors and buying my neighbor's golf cart (laundry, gas tank hauling etc... they're moving)
 
Nathan Osman
Nathan Osman
@Mateo I have an APU and a dedicated PCI-E GPU.
 
Mateo
Mateo
ah, cool
@hbdgaf monitors seem like they came in price, but a golf cart would be useful.
 
Nathan Osman
Nathan Osman
I also have a DisplayLink monitor, but that's a completely different ballgame.
 
hbdgaf
hbdgaf
displaylink working is a unicorn. if you catch it, you must surrender it for study.
 
Nathan Osman
Nathan Osman
2:51 AM
@hbdgaf I've done it twice in four years.
Once on an old Precise machine and on my Raspberry Pi.
It required a ton of Xorg.conf hacking (and who knows what else).
 
hbdgaf
hbdgaf
i've seen lots of crash and burn on displaylink attempts... but you're not exactly a "normal customer"
 
Mateo
Mateo
ahhhhh xorg.conf run!
 
hbdgaf
hbdgaf
@Mateo true. and i could catch a deal on it probably... since they're moving and not using the sale to subsidize another purchase.
 
Nathan Osman
Nathan Osman
@hbdgaf It also drew too much power when connected to the Raspberry Pi (it's bus-powered) so I had to connect it to my 4-amp battery.
 
hbdgaf
hbdgaf
I don't know why there isn't a raspi usb power amplifier module snap-on or power pin stand-offee feeds exposed so you can just use external wires for that...
 
Mateo
Mateo
2:54 AM
yeah, screens will keep dropping in price
 
hbdgaf
hbdgaf
obviously, pin stand-offee feeds was a technical term
@Mateo yes.
 
Nathan Osman
Nathan Osman
USB chargers that supply >2 amps are surprisingly rare.
I don't have any. Fortunately my battery charges at 4 amps.
It's rated for 12,000 mAh, so it holds a fair amount of power.
 
Mateo
Mateo
 
hbdgaf
hbdgaf
i was more thinking a way to plug in a powered usb hub adapter to the board. You could just use the powered hub I guess.
 
Mateo
Mateo
usb wall plug ;) , nice for phones and devices, we have one that has a regular plug and 2 usb for our kitchen
 
hbdgaf
hbdgaf
2:58 AM
What if it were a powered hub off the same battery? That way, you could circumvent the protection on the board and just pass more power as needed through the power pins on the hub?
 
Nathan Osman
Nathan Osman
3:13 AM
Possibly.
 
hbdgaf
hbdgaf
I'm not saying it should be a design goal, but wouldn't it be nice to be able to say if your battery has enough horsepower all your peripherals will work as opposed to "your peripheral is incompatible with the raspi"?
 
Nathan Osman
Nathan Osman
Is there any way to do this with a dual-head graphics card?
 
hbdgaf
hbdgaf
we're back on multi-seat? idk. i haven't tried it.
 
Nathan Osman
Nathan Osman
Everything I've read so far talks about multiple cards.
BRB. I'm going to reboot and enable the integrated GPU in the BIOS.

Q: WINE app is visible on all workspaces

Kalamalka KidWondering how I might go about making a wine app window (in this case poker stars) to be only visible in ONE workspace. Presently the default is that whenever I open this it is visible on all workspaces, and since there is no dropdown menu like the UNITY windows, I can not select which workspace ...

evening!
was curious to know if anyone has ever experienced removing numerical values after a file name extension in terminal? I looked for a question but I have never run across this before
 
Seth
Seth
4:43 AM
@Matt I think you're going to have to be a bit more specific than that ;)
Can you give an example?
 
Matt
Matt
ya you're right
so I was given several hundred files for a project
 
Chan-Ho Suh
Chan-Ho Suh
it's much simpler if the extension doesn't have a digit in it
 
Matt
Matt
they have foobar.jpg?=12456 and Im trying to find out how to loop through all hundred and remove after .jpg
 
Chan-Ho Suh
Chan-Ho Suh
ah, even better
you can remove everything after ?, as long as foobar won't contain ?
 
Matt
Matt
so I will have 1foobar.jpg?=12, 2foobar.jpg?=132 etc, etc
 
Seth
Seth
4:45 AM
Is it always ?= ?
 
Matt
Matt
yes from what I can tell
I was trying to find a way to do it with SED but Im not seeing a solution
 
Chan-Ho Suh
Chan-Ho Suh
if foobar never has '?', you can use s/\?.*//
 
Matt
Matt
and in the loop I cant set for all *.jpg because it appears its looking for the end
 
Seth
Seth
are all the files in a folder together?
 
Matt
Matt
ya
 
Seth
Seth
4:48 AM
cool
 
Matt
Matt
I looped through all the files and pulled them into a parent directory then deleted sub folders VIA command-line
 
Seth
Seth
I just tested this and it works (using Chan-Ho Suh's sed): 
for i in *; do mv $i $(echo $i | sed s/\?.*//); done
don't go using it just yet though.
 
Matt
Matt
ya I tried that earlier and I got an error
 
Seth
Seth
oh?
Funny, it worked for me.
Perhaps I didn't replicate your setup well enough?
 
Matt
Matt
usage: mv [-f | -i | -n] [-v] source target
mv [-f | -i | -n] [-v] source ... directory
usage: mv [-f | -i | -n] [-v] source target
mv [-f | -i | -n] [-v] source ... directory
 
Seth
Seth
4:51 AM
What command did you use? Can you paste the whole thing, even if it looks the same as mine?
 
Matt
Matt
for i in *; do mv $i | sed s'/\?.*//'; done
I was trying out rename earlier
 
Chan-Ho Suh
Chan-Ho Suh
that pipe shouldn't be there
 
Seth
Seth
mv takes two arguments but the way you're piping it only sends one :)
In my example the first $i stands for the original file and everything in the $() evaluates to the filename without everything past the question mark so the final command becomes: mv 1foobar.jpg?=12 1foobar.jpg, if that makes sense.
 
Matt
Matt
ya that makes sense but even applying your method Im getting the same error, weird
 
Seth
Seth
The only problem with a for loop is it doesn't handle weird filenames well (special characters, spaces, asterisks, etc) and if something like that were to exist it might mess things up badly.
@Matt hmmm. Can you paste the entire output from the terminal? In the meantime I'll look up a better alternative.
 
Matt
Matt
4:56 AM
oh.... blah.. I see why, they gave me files with whitespace, that's what it was
going to have to sed for that then run it and it works
whitespace is the devil, lol
so how you guys doing today? and much thanks!
 
Seth
Seth
I was actually just heading to bed lol.
 
Chan-Ho Suh
Chan-Ho Suh
same here
 
Seth
Seth
hmm, I can't get find to pull the files out :/
 
Matt
Matt
ya I need to do that soon.
 
Chan-Ho Suh
Chan-Ho Suh
just deleted my much longer answer with parameter expansion for complicated filenames..
good night :)
 
Matt

4:59 AM
I just read about gnome's issue with Groupon, much respect lost with groupon
later!
 
Seth
Seth
@Matt Well I can't get find to do it at the moment, too tired I guess.
If my previous command doesn't quite cut it (there are numerous reasons why it wouldn't) you could ask a question on the site itself.
We have several much better sed experts than myself :)
I gotta hit the pillow now. G'night!

Nowadays I feel like Ubuntu for Desktop has become stagnant. As canonical is busy with cloud and phones, desktop OS seems to be a "garage project" now.
 
Oli

@RegisteredUser I think the people working on it would disagree with that. They're trying to do some fairly major things (Mir, Unity 8, etc... whether that's a good idea or not is a different matter) but they taking serious time to accomplish.
 
Registered User
Registered User
@Oli But Mir and Unity8 are being developed to integrate the mobile platform well with the desktop one. People surely won't like Ubuntu phones not working with Ubuntu desktops itself. Also, nowadays managing a desktop optimised OS is no useful for any professional company. So I won't be surprised to see Upcoming Ubuntu versions to look like made for phones or touchscreens to generalise(like window 8 does).
