• I cant see my windows drive in ubuntu

  - by Shardul Dhande

  I'm n00ber than any n00b you ever seen, so bear with me... I just downloaded wubi and installed ubuntu 12.10 along with Windows 7 on the same HDD. Linux works fine, but doesnt show files from drive C (on which it is installed). I really need C as it contains all my files. I did df -h in the terminal. It does show the drive. /dev/sda2 577G 220G 358G 38% /host Now I tried to mount the drive sudo mount /dev/sda2 and got the response mount: /dev/sda2 already mounted or /host busy mount: according to mtab, /dev/sda2 is already mounted on /host I dont know what that means. The drive doesnt show up in HOME FOLDER. What am i supposed to do now?

• Holiday Stress

  - by andyleonard

  Photo by Brian J. Matis Ever have one of these days? I have. According to studies like this one , I am not alone. This is a time of year when vacations loom right alongside project deadlines. There are parties to attend, additional expenses and work around the house, decisions about what to do for whom, and more. If you celebrate by decorating a house, tree, or lawn with lights; you may find yourself fighting them like the young lady pictured here! Stress at work, stress at home – stress everywhere!...(read more)

• MVC helper functions business logic

  - by Menelaos Vergis

  I am creating some helper functions (mvc.net) for creating common controls that I need in almost every project such as alert boxes, dialogs etc. If these do not contain any business logic and it's just client side code (html, js) then it's ok. My problem arises when I need some business logic behind this helper. I want to create a 'rate my (web) application' control that will be visible every 3 days and the user may hide it for now, navigate to rate link or hide it for ever. To do this I need some sort of database access and a code that acts as business logic. Normally I would use a controller for this, with my DI and everything, but I don't know where to put this code now. This should be placed in the helper function or in a controller that responds objects instead of ActionResults?

• How should a site respond to automated login attempts with phony usernames?

  - by qntmfred

  For the last couple weeks I've been seeing a consistent stream of 15-30 invalid login attempts per hours on my site. Many of them are non-sensical usernames that nobody would ever register for real, and often contain typical spam-related keywords. They all come from different IP addresses so I can't just IP block/throttle the requests. I'm not worried about unauthorized access to real accounts since they aren't using real usernames. And if it were a member of my site trying to brute force logins, they could easily scrape the valid usernames from the site, so I'm not worried about that kind of malicious behavior either. But what's the point of this type of activity? What would whichever bot operator is doing this have to gain by attempting all these logins?

• How do I show a minimap in a 3D world?

  - by Bubblewrap

  Got a really typical use-case here. I have large map made up of hexagons and at any given time only a small section of the map is visible. To provide an overview of the complete map, I want to show a small 2D representation of the map in a corner of the screen. What is the recommended approach for this in libgdx? Keep in mind the minimap must be updated when the currently visible section changes and when the map is updated. I've found SpriteBatch(info here), but the warning label on it made me think twice: A SpriteBatch is a pretty heavy object so you should only ever have one in your program. I'm not sure I'm supposed to use the one SpriteBatch that I can have on the minimap, and I'm also not sure how to interpret "heavy" in this context. Another thing to possibly keep in mind is that the minimap will probably be part of a larger UI, is there any way to integrate these two?

• how to find available wireless networks

  - by Quinn

  I'm using an HP Pavilion dv6000 I've looked at other answers similar to this question how ever when I look at my network symbol it doesn't say anything that the answer below says "Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right. Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears." it how says 'Enable Networking' my wi-fi switch is on and I've tried using terminal to kill the applet as another answer suggests trying. Does anyone have any other ideas that might help? Just in case anybodies curious as to how I'm posting this I'm on my other ubuntu laptop that's running an older version.

• Why does Google Analytics show false referrals?

  - by Peter Merrill

  Ever since Google revamped their Analytics interface I've been noticing a weird "bug" while viewing the "Real-Time" overview area. From this area I can obviously see live stats of visitors to my website but when I visit my website by opening a new tab (Chrome) and manually visit website the real time stats sometimes look like the image linked below. http://i.stack.imgur.com/mfniY.png Is there any reason why Google is saying that I was referred by Stack Overflow when I'm visiting my website from a new tab? Could this be something do to with how I installed the analytics on my site or could this be an issue with browser cookies? Have anyone else noticed this? I am mainly concerned about this because in the standard reporting area of my Analytics panel my referral stats are getting thrown off every time I visit my own website.

• How do you set up PhysFS for use in a game?

  - by ThePlan

  After my recent question on GD I've been advised to use PhysFS to pack all my game data in 1 file. So I have, and the decission wasn't light, because I've tried out every library in my answers but none contained a single good tutorial whatsoever, in fact PhysFS is the poorest documented library I've ever seen. After attempting to set up PhysFS in my game I realized it's not as simple as adding the headers to the project, it appears something much more complicated, in fact after my first attempt to install PhysFS the compiler ran out of memory to display errors, it reached the critical count of 50 errors. So basically what I'm asking here is: How can I set up PhysFS on my game? I'm using Code::Blocks IDE on Windows XP SP3;

• Split screen and other issues on Ubuntu 11.10 with ATI graphics card

  - by garus

  Ever since updating my Ubuntu 11.04 to 11.10 I experience issues with graphics. The biggest is the "split screen" effect where my desktop is shifted to the right, resulting in having Unity bar in the middle of the screen. As shown here: http://i.imgur.com/I8nmZ.jpg This changes from boot to boot, sometimes it's on the left, sometimes in the middle. What I tried: Removing fglrx drivers completely Installing post-update version of them, but installation is broken ATM in the Ubuntu, so no go. No one is even trying to fix it (bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/873058 and a couple of duplicates out there) Also using the open source "radeon" driver results in the same (I have a better successful boot ratio with this one, proprietary rarely lets me boot) Other artifacts are: serious screen tearing weird lines flickering in random places lagginess Did anyone experience that? My specs: Ubuntu 11.10 AMD Radeon HD 6950 1GB

• Ubuntu reports low battery capacity on my Dell Vostro

  - by Jeff

  I have a Dell Vostro 1500. Before I wiped Windows XP off my hard drive in 2009, I had a full ~7 hrs battery capacity. I installed Ubuntu 9, and the capacity immediately dropped to about 27% (and has since decreased to about 11%). I couldn't figure out what to do, so I've just lived with the 20-30 minute battery life ever since. I upgraded to Ubuntu 10, and the issue remained. I wiped my hard drive clean again and installed Ubuntu 11, and the issue still remains. I tried what they told me in the forum here, but it didn't do anything. Is it possible for a battery to suddenly lose most of its capacity?? Or is there a bug in the power management software?

• Managing time for success in the industry? [closed]

  - by nvillec

  So about a year ago I decided to pursue programming, specifically game development, as a career. I've always been a pretty avid gamer, from chucking turnips at Shy Guys' faces in the 90s, to downing Heroic Deathwing last week. Just recently though, I've been spending a LOT of time playing games and it's starting to show in my programming classes. Yesterday after a discouraging exam, I put my foot down and vowed to myself to keep the gaming:coding ratio in favor of the one that will hopefully pay the bills later on. I realize that knowing games well is a key part of being a good developer, but as I've been recently shown, there's a threshold of pixelated indulgence that must not be crossed if I'm ever going to land my dream job. I'm assuming many of you are quite enthusiastic about games as well. What advice would you give an aspiring programmer regarding time management? Thanks!! (Also, I'm brand new to Stack Exchange...if this belongs somewhere else, I'm happy to move it)

• What's the DCPU-16 thing all about?

  - by ChrisRamakers

  Ever since Notch (of Minecraft fame) announced his next project will include programmable 16bit cpu's ingame everybody seems to want to write VM's for the spec notch has written up. I've seen em written in C, C++, go, javascript, coffeescript, ... Can anyone enlighten me what's so special about the spec notch wrote up or is it just that it's the first game that actually contains a CPU ingame that you can do whatever you want with? It sparked my curiosity but I fail to grasp the thing that makes it so special suddenly everybody needs to write up code for it?

• Hacked by our own hosting company!

  - by dazhall

  OK, so our hosting company decided to clone our site and database onto a new serve. Without our knowledge or permission they then edited our code to point to the new database. The old server was left running, still pointing at the original database. The DNS was changed to reflect the new IP address of the server. Obviously during the propagation customers were hitting both the new and old servers, resulting in orders coming in to both databases, sometimes being split between the two. We're now attempting to reconcile the two databases. The question I have is is it still hacking if it was done by your own hosting company?! I'm fairly sure they shouldn't have edited our code! If they had left it as it was the site would have stayed pointed at the original database and we wouldn't be in this mess! I'm thinking that legal advice is need but just wanted to know if anyone had ever come across this situation before?!

• My Reverse DNS PTR record seems to be right, but I'm still getting bouncing email

  - by johnbr

  Hello, I have a service (statusme.com) where I let people know (for example) that their kid's soccer games are cancelled because of bad weather. We send out emails to the people who have registered. I have a second server as a backup, (vps.statusme.com) and I've set up the application to send some of the email through the second server. But I'm getting complaints from various recipient SMTP servers that the email is considered spam. So I did some investigating, and it appears that they think my reverse DNS record isn't correct. But when I look at it via various rDNS websites and instructions I found elsewhere on ServerFault, everything looks correct: jb$ host -t a vps.statusme.com 8.8.8.8 Using domain server: Name: 8.8.8.8 Address: 8.8.8.8#53 Aliases: vps.statusme.com has address 66.84.8.246 jb$ host -t ptr 246.8.84.66.in-addr.arpa 8.8.8.8 Using domain server: Name: 8.8.8.8 Address: 8.8.8.8#53 Aliases: 246.8.84.66.in-addr.arpa domain name pointer vps.statusme.com. I'm confused about what I'm doing wrong. Thanks for any suggestions.

• How to share text, pictures and video to restricted set of users

  - by joaoc

  I want to share pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to add material and then share with grandparents and friends who would be given a username/password or some other solution that authenticates them. This content would preferably be available remotely over the internet or downloaded periodically to the allowed viewers computers. The second option most likely means they would have to install a client, which I am not too fond of doing (I would have to ask them to install it, help configure for different platforms, ...) I'm at the start but I would like software that also allows export of the data (if one day I want to migrate to a different solution). Folder sharing I don't know if Windows folder sharing is reliable, robust and safe enough to share over the internet. Dropbox could be a software solution, but it's limited to 2GB and requires receivers to also install and configure software. A folder is just a collection of files, so it would be harder to keep them organized with text describing the pictures/video Email I could email the content every now and then but videos are almost always too big to go as attachments This would also not provide a history of updates to anyone just recently joining in Are there other solutions to achieve this? NOTE: I also thought that software to run a local or remote blog could be an option but we aren't allowed to ask those questions on superuser because one admin doesn't like cloud-computing questions. But if you do think it's the best approach and can suggest a solution, do state it in the answers anyway!

• What is Perl's relation with hackers?

  - by K.Steff

  I know Perl is a language revered by many hackers (as in hacker vs cracker) and respected by many good programmers for its expressiveness. I also realize it is useful to know and it's very handy at generalizing common Unix tasks (Unix here includes Linux and Cygwin). I also know that being a good hacker probably means you're a good programmer in general (references on this one are sparse around the web, but about everything Paul Graham has ever written seems approving of this statement to me). So my question is whether there is a reason that attracts hackers to Perl in particular? Will learing Perl improve my general programming, problem-solving and hacking skills if done properly? Does it present unique tools that are more useful to a hacker?

• How to Root Your Android Device & Why You Might Want To

  - by Chris Hoffman

  You’ve probably heard of people “rooting” their Android phones. If you’ve ever wondered how to do that yourself – or wondered why people would bother – you’re in luck. You can root your Android in just a few minutes. After rooting your device, you have full access to the entire system and can run special types of apps that require root permissions. These apps can disable bloatware, control app permissions, enable tethering, and do lots of other cool things.

• Creating a bootable USB recovery drive to be used by someone who isn't computer savvy

  - by David

  I am looking for a way to prepare an image of an Ubuntu machine which would be bootable and installable in the easiest way possible. I'm actually preparing an Ubuntu machine for someone living far, and not computer savvy. If he ever has troubles with his installation, he could just put a USB drive in, boot the machine and everything would be resetted for him. I know there are many methods of creating/loading an image of a drive, but the ones I've found so far have complicated menus with several options to choose from, etc. Ideally, perhaps only asking a Yes/No question such as "Would you like to reinstall?" would be great. Does such a tool exist? Thank you in advance!

• How to be a zero-bug programmer?

  - by Elaine

  My boss ever told me that as a good programmer, who should be able to ensure the code he/she changed must be reliable, correct, thoroughly self-verified, who should completely understand what all the results and impacts that he/she did or revised will cause. I did try my best to be as this kind of programmer, test again and again. But.. bugs are still there. How could I be a zero-bug programmer? know every char of my code will cause and effect?

• .NET Reflector is no longer free - how does everyone feel about this? [closed]

  - by Schnapple

  The upcoming version of .NET Reflector, coming in March, will no longer have a free version. .NET Reflector started out as a free utility written by programmer Lutz Roeder and quickly became fairly indispensable to a lot of programmers. After about four years he sold it to RedGate software, who has maintained a free version ever since, as well as a "Pro" version about a year ago which adds capabilities and starts at $99/seat. The new version will no longer have a free version, will be $35 for the non-Pro versions, and the existing free versions will still work until the end of May. On the one hand it's annoying that the existing free versions will die and obviously I'd prefer there be a free version going forward. On the other hand I respect where RedGate is coming from and the cost for a license isn't prohibitively expensive. Plus it may encourage more frequent updates. EDIT: I originally said it was $35 for everyone but according to this FAQ there's still going to be a Pro version.

• If you had two projects with the same specification and only one was developed using TDD how could you tell?

  - by Andrew

  I was asked this question in an interview and it has been bugging me ever since. You have two projects, both with the same specification but only one of these projects was developed using Test Driven Development. You are given the source for both but with the tests removed from the TDD project. How can you tell which was developed using TDD? All I was able to muster up was something about the classes being more 'broken up' in to smaller chunks and having more visible APIs, not my proudest moment. I would be very interested to hear a good answer to this question.

• Changing default application

  - by ragebunny

  Hey i have recently installed Sublime text 2 and i must say it's one of the best text editors i've ever used or even seen in use. So i managed to install everything and added to the unity menu and also change all the entries of gedit.desktop to sublime.desktop and it works just fine for most files but i realised that some files still open in gedit, for example php files, i checked the default list for php but there isn't anything in there. So how would i set the default for opening php files? Update:Also Sublime doesn't show up in them properties menu where i can usually select the default program. Thanks for the help. I'm using 12.10.
