Is about to die
I'm trying to install OpenOffice on Ubuntu 14.04. I downloaded the tar.gz file, extracted the contents, double clicked the main desktop integration .deb, and attempted an install with Ubuntu Software Center, but it fails at the last second.
Package operation failed
The installation or removal of a software package failed.

What should I do?
I just realised I can pirate lynda courses but there's too much choice and I don't really have much of an idea of what I'd like to learn about
What are some basic things that would be useful to know?
should I use manjaro xfce edition or xubuntu?
So I need to backup both a Windows system and a Linux system to one external hard drive. My first thought was to have multiple partitions but the required space for each system may change at any time.
Is there either
1) A reliable way to mount ext4 r/w on Windows
2) A reliable way to backup an ext4 filesystem to NTFS without losing any metadata?
I wouldn't worry about anything below 90 if not overclocking. Anything less will only make the fans get noisy sooner, assuming the capacitor plague is over and you didn't lose the GPU lottery.
I accendentally posted to 4chan with only 6 of my 7 proxies up. I'm afraid NSA and fecesbook will take control of my mind and also use the content of my post to give me more accurate ds. Here is my post,
>tfw no gf
Privacy is obviously ruined, should I kill myself before our NSA overlords come and steal m [strikethrough]anime and 4chan reaction pics [/strikethrough] really leet haxor sekrits?
If I stack md, lvm2 and drbd, can I still take a usable image of /dev/sdX?
Is it possible to open up the Wii U Pro controller and mod in the 360's triggers so I can get analogue? Or on the other hand, mod a 360/xbone controller so the sticks are in the same position as the Wii U pro controller? This is for PC use.
somebody want to explain to me why half of youtube videos simply refuse to load? google tries to say it's my isp's fault on the page but that's bullshit because it happens nowhere else.
baump. Can I just pipe rsync to tar to a file on an NTFS system, and expect to restore it okay?
Not necessarily bullshit. Many ISPs operate caching proxies for things like youtube, and they're usually pretty shit and end up making things worse.
Is it possible to play videos one after another in mpc-hc? pic related, the videos I want to watch in sequence.
As in HUGE and time consuming.
No. Even if you did manage to solder the trigger modules to the board correctly, you'd have to somehow write software to interpret the hardware signals. It would honestly be WAY, WAY easier to mod the core 360 controller internals into the Wii U Pro casing. Now THAT is a solid maybe, and a project worth undertaking.
Oh man. I use several times that every day streaming video on my phone. What third world shithold do you live in :(
Yes it will be okay for 4chan if you mainly frequent text-heavy boards like /g/. Not image based boards though. Many sites are way over an MB nowadays though, you will run out fast if you aren't careful.
Consider a browser like Opera Mini which compress everything, and be sure to switch off all sync and update services.
let's say i have a folder which catches pictures, music, audio files, archives, etc by FTP from another server.
are there any (linux CLI) utilities to sort and place the files in a logical fashion?
I have a HP pavillion dv6000 piece of dicks laptop, ive got mint on it as windows was running slow on it. Its still shit. Can i atleast somehow use it as a second monitor for my desktop?
It has DvI, Expansion port 3 (i dont know either), and an hdmi. The DVI and hdmi are probably both solely output. So am i boned?
Oh, you really are in the third world. I was kind of expecting you to be in the US where the data plans are apparently horribly capped, and was implying that the US is third world. Okay.
I don't think Clover has a compression feature, so either use Opera Mini or turn off images altogether.
Sure, just solder it to a wire then run that up to the other hole. You have to do the same for the face buttons. Look at how they make portable N64's for instructions on board modification.
like something that can manage individual folders for each type of file, move things into place, change their privileges so they can be used by users/programs, possibly rename files and find and organize by metadata...
i'm pretty sure i can make it, but i wanted to check to see if something like it exists first.
No website seems to agree on what specs that laptop has. One implies that it has 512MiB RAM and yet they shipped Vista on it, holy shit.
Anyway first check that it isn't overheating (use the "sensors" command in a terminal). Then try Lubuntu, Mint MATE, or something else lighter than Cinnamon. You can definitely get a usable Linux desktop on it.
As for using it as a screen, a remote access system over the network is the only way you'll get something like that.
That was one of HPs worst series ever. For like 90% of people with it, The keyboard, touchpad, screen, HDD, CD drive, etc. All broke randomly until the laptop became unusable.
The fact that one is still running amazes me. I stopped using mine because the HDD stopped working after two years. I kept it all this time and put a new HDD in January. It's not good for anything

I know they're packages compiled for different architectures. I know i686 is newer shit. I can't find any references to i386 to get gentoo on an old machine for testing. I'm assuming they're not compatible but I don't fucking know.
If i were to get an older PC with no USB ports, how hard would it be to move files from it? It has windows 95 on it, I don't think there's any real Parallel to USB adapter's that aren't just for printer's are there.
is there a way I can "save" youtube searches so my kid can pick up my phone and search for videos?
for example, if he wants to watch "pokemon" or "barney", he would just click an icon or image (since he can't read). doable?
What's a good icon pack that goes well with voxel
I'm having trouble finding icons for all my apps
Also are there any better alternatives to Chanu on Android
I'm not having problems with it, I just want to know
If I could also add another note: I tried many OSes from Vista SP2, Win 7 SP1, Win8.1, eOS, and finishing with Damn small Linux (32 bit for reference, this laptop was available later 64 bit), the problem was mainly with the motherboard + bios.
The hardware works (in other computers surprisingly) but the motherboard had trouble recognizing the hard drive, USB ports, and the bios for god knows what reason fought with me to update. The reason I did an update was because the laptop crashes upon bios post without warning or reasoning
how to enable unicode for my i3 configs?
I stole some configs from another /g/uy and am greeted with the i3 error message
ERROR: CONFIG: syntax error, unexpected <word>
ERROR: CONFIG: in file "/home/james/.i3/config", line 151:
ERROR: CONFIG: separator #171a1f
github of the configs: https://github.com/Axioen/dotfiles/tree/master/.i3
Another user commented that it may be due to not having unicode enabled.
I got a Dell Inspiron E1705 for free from a friend. Everything is OK with it except for the mouse. The trackpad works, but the mouse buttons don't except for the right one, and whenever I drag the mouse it selects text. it acts the same way when I plug in an external mouse. how do I fix it?
I'm always wary of what he's watching. It's not like I leave him unsupervised. It's just that depending on what he wants to watch, he likes being able to switch them by himself
Is anyone in WESTERN AUSTRALIA? Does anyone know of any good shops to buy circuit parts, like an equivilant to the American radioshack? It would be favourable if they were in Perth, but anywhere is fine
Uhh.. fuck. My chip's not listed under 3, or even 2. The sticker says Pentium Inside. I didn't think it was this old.

use dolphin browser or any browser app that can save bookmarks to the home screen.
go to youtube.
make your search.
press the dolphin
look for Add +
add to home screen.
then change the name of the shortcuts.
Bitch isn't posting. Pic related.
I plug it in, flip on the power supply, press the big red IO on the motherboard (or the case, same thing)–nothing happens.
The power supply doesn't whir.
The fans don't whir.
No LED. No beep.
The 24-pin is in, the 2x4 CPU is in. Two sticks of RAM. There's not one unconnected cable.
Is it the power supply? If the power supply worked, it would be operating if I turned it on, wouldn't it–even without the motherboard?
Why is Fedora (or Xfce) doing this shit whenever I boot my thinkpad without a battery in it?
use nova launcher or any launcher that lets you edit any shortcut on any home screen.
with nova launcher you can edit the name plus the icon image.
so download an image related to your youtube search from google images.
using nova launcher
long press on the bookmark.
edit shortcut menu comes up.
press the picture.
gallery comes up.
choose the pic you downloaded before related to that youtube search.
I've been experiencing blue screens with different error codes each time. I can trigger it after some moderate to heavy use in Adobe Lightroom. And instances during seemingly random usage (browsing, idle, etc).
Are these results conclusive evidence that it's the RAM? I made a topic last night but it's long gone now.
I'm installing xubuntu on a large partition of free space and I would like to use an encrypted lvm but there is no guided option for something like that. How can I do it manually?
i think your left touchpad button is physically broken.
disable the touchpad from it's properties and then plug in a usb mouse, it should work normally.
if that doesn't work, go to device manager and uninstall the touchpad driver. reboot and let windows detect it again.
>Are these results conclusive evidence that it's the RAM?
yes they are. a single error means the stick is bad.
now you have to figure out which one (assuming you have 2). remove a stick and start all over again. i usually let it run overnight. then do the other one.
it sucks, but that's life. it's likely only one dimm is bad and not both.
Okay, thanks for the answer. They're 4 x 2GB sticks of A-Data RAM. I definitely don't have the patience to test each stick individually since it requires me to remove the Noctua. I'll just replace them with 2 x 4GBs
What do you guys think of my upcoming build?
My original budget was $4000, but I'm fine with going a little over.
And before you ask, the answer is yes. I do need this much power.
Newbie here. I've got very little programming experience, envision Bucky's tutorials on Python and C++. I'm looking for getting into C#, which books should I try first (from the gentoomang library)?
If I cut and paste the files and folders out of Appdata, then mount a drive/volume/virtual drive to C:/Users/Anon/Appdata, then cut and paste the files and folders back in, will it break anything?
Essentially, can Appdata be on the "D" drive without causing software problems so long as "D" shows up as a mounted drive at Appdata?
>What do you guys think of my upcoming build?
you know haswell-e is like a month away, right? that would be 8 cores / 16 threads for the same price, cowboy. not to mention a new chipset, quad channel ddr4, etc etc
there are other issues with your build, but i think most of them stem from you being a faggot. i would advise you to learn a little about computers before you spend $4k on one. just picking out the most expensive parts doesn't make the best machine.
Best $100-$150 smartphone for Sprint? So far my best guess is the Galaxy S III (~$130 on Ebay). I've seen a few Moto Xs in the price range, but the cell service I'm getting (chit chat mobile) doesn't support it. Actually, on that note, what cheap data plans do you guys recommend? Chit chat mobile is $15/month.
it's fucking amd_64 dingus, but you can do i686 if you don't have more than 4gb ram
Once you have the link setup it should work fine, but you might run into problems in the time between when you move everything from appdata and setup the link if you have something trying to use it then.
I never upgraded from i386 because of money problems. So my CPU knowledge is sub-par.
if gentoo is compatible with i386 I'll eventually figure out how, but it's nice to know there's a result to find rather than searching blindly.
Okay, that's what I figured. Thanks!
Another question, if D: is just holding files and doesn't have any boot info on it, can I add a partition without backing up to an external and wiping it? I can use Defraggler to move everything to the beginning physical disk locations and then partition the end, but...will Windows let me?
Alternately, can I link a subfolder of a drive mounted to, say, Program Files to Appdata, or does it have to be a separate partition?
my guess is you would have to download the videos
open the videos in different windows and select a different audio device for each video.
Alternatives to LastPass? I recently decided that it might not be a good idea to give password information to a company like LastPass. My mom has used KeyPass for years, but first and last time I used it, it corrupted the master key file and I lost all of my passwords. Should I try KeyPass again or do you guys have good alternatives?
I don't think windows lets you shrink partitions after they've been created. If you have space on the dirve that hasn't been put into a new partition you can create one out of that, but otherwise you'll probably have to nuke the partitions on the drive and repartition them.
If you just want to move your appdata folder to another drive you don't need to create its own partition for it. You can create a symbolic link from appdata on C to appdata on D. The appdata on D can be basically anywhere you want on the drive in terms of the folder hierarchy.
>there are other issues with your build, but i think most of them stem from you being a faggot. i would advise you to learn a little about computers before you spend $4k on one. just picking out the most expensive parts doesn't make the best machine.
Hahahahaha eat shit, kiddo. I have been building PCs since before you were born and I've worked in the computer hardware industry for 15 years. I know exactly what parts I picked out, and I know exactly what they do. You're mad because you're jealous. I understand that. But I suggest you think about what you're saying before you spout your ignorant mouth off. You don't know who I am. You don't know what I do. You know nothing about me. So again, please think before you speak.
What the fuck is going on with my torrent client?
It was at 15-20 kb/s and now it just stopped all of a sudden
I like eye candy and KDE but the fact that it uses around 60 MBs of RAM at all times is fucking insane, and I made a minimal installation.
Is there any other way to know if your windows is activated?
What I'm using right now is a pirated copy. I believe I've done it properly. Used DAZ loader and shit. But whenever I go to control panel > system It doesn't show that my windows is activated and genuine. It was showing before but all of a sudden it's not there anymore. It's supposed to be at the very bottom of pic related, right?
I couldn't tell you why.
it looks like that page was customized by the vendor, in your case asus
on my machine that just tells me to enter an activation key, it never mentions that it is already active
Okay, /g/. I got a doozy here.
I'm looking to get a new cell. Not looking to root, only to have something that works, and has the basic smart phone capabilities (navigation, browser, etc.), while still being overall an effective platform hardware and software wise. Is this impossible? Price range isn't a huge deal. Any suggestions / personal opinions are welcome.
If it was that easy no-one would ever hit their data cap you moron. Get a second line or use someone else's. The ISP tracks this shit, that's like thinking that editing the CSS on facebook locally will magically change the served file.
So i spilled a shitload of rum and coke onto my laptop. Does the rice trick that works for smaller electonics help? Or should i just pull my hard drive and hope it isnt wrecked and will transfer my files.
In what language were sites like IMDB, Discogs or RYM coded in? What level of proficiency do you need to create a site like that?
>What does VPN traffic look like from the ISPs point of view?
Well is there anyway to bypass the bandwidth throttling? Like with using a VPN or something?
I live in a rural area where all we get is Cricket Broadband which throttles to 56k after 2GB a month.
Just curious if anyone sees a mistake I made here. Planning on making an always-on home server for VPN while at school, hosting assorted servers, and NAS.
No matter how many times I buy parts, I always get super paranoid I've missed something unbelievably basic.
well it would be everything tcp and udp, lots of plaintext, every ip you connect to, etc etc
to an isp, a vpn is an encrypted tunnel. there is the source ip (you) and whatever the address of the vpn server you're connecting to, and that's it. any data going back and forth is encrypted, so it just looks like gibberish.
It is. And the data piles up incredibly fast as well. Caps out after around 3-4 days even without me downloading things or streaming video. I do the bare minimum while browsing and it still is used up very quickly.
Can anyone advise me if a corsair hx620 can power two 760gtx? The hx620 doesn't have enough 8/6+2 pin connectors for the second card, but I thought I could get some molex adapters for it,
Thanks guys, I found a second 760 super cheap locally and want to know if I will have to buy a new PSU to power both
>who would willingly transmit all of that data to their ISP?
frankly, no one at your isp really gives a shit what you are doing so long as you pay your bill. the people that do care (nsa, lea, whatever) tap into isp's backbones to target people for surveillance.
fyi if you are the target of that surveillance, your $5 a month hidemyass account isn't going to do shit. while the cryptography still remains mathematically sound, they have demonstrated the ability to exploit the implementations and render it all moot.
if it makes you feel better, that's all that matters
>wouldn't the vpn still be able to see this info/data?
no. the vpn would see the incoming ip's and the outgoing ip's that you are connecting to, not the traffic itself. if they keep logs, well, that's that.
you are investing a large amount of trust in your vpn provider
OK, so after scouring the internet I have confirmed that $18/month is basically as good as it gets for smartphone data plans and the Galaxy S 3 is the best possible phone out there in the $100-$150 price range.
A good USB Wifi Adapter with GNU/Linux Compatibility?
My 2 year old $20 Netgear wifi adapter is shitting out. Connection is on and off and very very slow. Any recommendations preferably less than $50
Or should I just go PCI?
>download 50 GB of copyrighted torrents and porn a month
>have been using public trackers and dynamic IP the whole time
Should I be using a VPN? I have never been notified by my ISP for what its worth.
ISP's dont actually give a shit if people pirate.
Only if the RIAA or some shit pressured them into taking you down should you actually be worried, and even then it'd only be if you uploaded a ton of copyrighted music/movies, I'm talking like gigabytes. Everyone pirates and nobody really gives a fuck.
I'm trying to tweak my Android's kernel settings. But I don't know what about 75-80% of it actually determines. The explanations for them are not even remotely helpful and I just want to optimize the thing even if it's considered cosmetic. Is there a guide or an infograph for helping me understand what my kernel's values mean?
It tends towards about a 90% detection rate. Because it's so prevalent, what with being the go-to for Windows 7 and being packaged with Windows 8+, a lot of stuff is geared specifically to sneak by it.
MSE+Avira is what I go to.
because /g/ said so or because of no updates?
so see your options.
see which one is more lightweight according to you and flip a coin.
the more viruses their pc gets
more work for you.

Also why the fuck do batched TV show torrents come with all the episodes individually rared? What's the point?
I'm a comp sci student and want to practice web dev. I want to start with PHP/JS/MYSQL and then play around with ASP or JSP.
Problem is, funds and access are limited. I have an old laptop with Slackware on it, but slack doesn't register the ethernet or wifi.
As a result of having no DVDs to burn my CentOS image to, and just this Slack laptop, I'm trying to find out if there are any places on the web I can fuck around for free to practice PHP on for the time being.
Don't make your own server. Buy an unmanaged VPS and install ownCloud.
No problem. You just have to remember when you hop parts of 4chan, "What counteracts the point of this area effectively?" and you have a good range of stupid shit that a troll might do there.
In a place specifically made for help, providing obvious non-help is sure to trigger tards.
Making this worse most people don't use scripts to resolve and replace url shorteners (being at the whim of the person and the website involved) so they aren't sure what to expect and become psychologically invested when they click.
I ordered a bunch of parts for a home server with the intention of taking advantage of my parents' internet and electricity while I moved away.
Then I realized that ISPs really, really hate people hosting their own servers outside of their LAN.
The parts should be here in a couple weeks, I spent about $400. Should I just return them? Is there any point in me having a home server versus just renting some hosting space?
lookin' for something to complement my mbpr
seems like a good deal, my 128 ssd is going to only be for core applications and projects.
Two 1tb drives in RAID 0 or one 2 tb drive? Is the performance of RAID 0 worth the extra 30 bucks or will the 2 tb drive suffice. I just want speed and storage that's worth the money.
Can't decide what is better. I already have an SSD, 500gb hard drive and an external 1 tb drive all about full right now.
>Making this worse most people don't use scripts to resolve and replace url shorteners (being at the whim of the person and the website involved) so they aren't sure what to expect and become psychologically invested when they click.
Is there one that works for the way he's cutting out the colons and periods? My coding skills are shit so I don't know if I could make edits to my existing script.
>Two 1tb drives in RAID 0 or one 2 tb drive? Is the performance of RAID 0 worth the extra 30 bucks or will the 2 tb drive suffice. just want speed and storage that's worth the money.
Are you sure you don't want any redundancy? 2TB seems like a lot of data to lose if it all goes at once.
Just get an internal 1 tb drive for 55-60 bucks. If you're gonna need to move your data around, settle for a reliable external. The 1 tb versions always go in sale for 60 bucks, like everyday. If you play games then I suggest you go with internal.
Look up little tutorials about masking and wildcards.
For whatever script you're using, you could just add another entry that specifies that certain parts can be missing or any character, such as periods being whitespace.
At that cost you could probably just rent server space somewhere with enough quality to install a little web-interface for streaming your media.
Going over the internet to your home, then into your home and hoping it's always on is going to be much slower than what you can get just finding a cheap place to rent a box.
Motherboards nowadays can setup a RAID for you. I don't think a raid card is necessary unless they offer some type feature or maybe if you have an assload of drives. If you're only gonna have like 5 drives in your system, I see no reason to get a card.
You won't need anything special to set up your RAID.
If you plan to expand or modify your hard drive setup anytime soon, go with a controller. If you're looking to plan ahead (and for personal purposes are planning small) then you're fine without it since your drives are set.
RAID IS NOT A REDUNDANCY PLAN. This is a big mistake, and I have to put it here just in case you are looking into it for that reason.
<<<This SSD on SATA I, ye' or nay?
I just bought one of these
To slap into my grandparent's laptop. What I didn't realize at the time, is that it's an original SATA interface. Is it a waste to install it when it's capped at 150mb/s?
All my machines already have SSDs and I got a real good deal on it. (Microcenter had it on sale for $59.99, I had a $10 off coupon, so I payed about $55 for it after taxes)
>RAID IS NOT A REDUNDANCY PLAN. This is a big mistake, and I have to put it here just in case you are looking into it for that reason.
What do you mean you need an offsite to make things 100% safe?
I think he means that being able to remove a drive or two isn't redundancy but efficiency. Yeah, you can keep rolling but it isn't out of security but out of convenience.
If you're doing it for redundancy of data you only have to go so far as imagining some minor electrical internal damage or a surge. That'll fry your board and can easily take out all 6-10 drives without any kind of exaggeration.
On the other hand, just splitting your setup in half gives you a redundancy you can rely on.
There are tons of ways to rig it so you have a safe backup. This doesn't even encounter going so far as offsite, although if you want to get clever, there are some fucking mindblowingly awesome and easy black-friendly offsites you could do that would be untraceable and hidden to anyone but you.
> you only have to go so far as imagining some minor electrical internal damage or a surge
And I suppose in a situation like this one a surge protecting power strip wouldn't be enough?
>there are some fucking mindblowingly awesome and easy black-friendly offsites you could do that would be untraceable and hidden to anyone but you.
If I ask for examples or price ranges you're not going to tell me to google it are you? I'm curious as to how much it would run me to offsite my RAID server.
All the VPS providers I've seen so far don't seem to offer the amount of space I'd require. My home server is 8TB and I've filled up 3 of them already. Am I missing something?
I need recommendations for backup software. One thing that's bothered me about every program I've seen so far is that even when files are deleted from the main computer, they remain archived on the backup. I know that the backup tool in Mint has an option of overwriting upon checksum mismatch, something like that would be great.
Also, it needs to be free (gratis) and compatible with Windows 7.
