• fingerprint-gui can not recognize my upek reader (147e:1002)

  - by ymfoi

  I've got a new laptop which is Lenove's E420s. And I have encountered a big problem that I can't make the fingerprint reader work properly. I've also tried fingerprint-gui. But unfortunately, it's told that "No Device Found". Here is my screenshot: http://ge.tt/98Xg2WD/v/0 It's said that 147e:1002 is supported by fingerprint-gui on the official website. So, I'm curious about the situation. Anybody knows? P.S: I'm using gentoo, but I think this problem may not have anything to do with distribution since I compiled the source from official site.

• Is someone aware of any multi threaded unrar program?

  - by rsz

  I was searching in the past (past few weeks) for a program/software which is multithreaded and it is able to extract rarparts using multi threading. What software's i've already tried? unrar, unrar-nonfree, rar, 7zip It seemed to me that none of them is multi threaded and therefore they are all slow. The solution would be needed in cli format so if not necessary the no gui. Is someone aware of something like this? I asked on other irc's for suggestions and they told me, that the best is to write one myself. I may be agree with them, but i don't have these type of knowledge to achieve this task.

• 12.04 LTS won't install from CD

  - by Rob Hays

  I've been trying to install 12.04 LTS onto a Dell with a PIII from CD. Booting from the CD the install gets through the "Who are you" process, begins copying files. The progress bar gets as far as the last period in "Copying files...". The box clears, and an error box comes up "The installer has encountered an unrecoverable error. A desktop session will now be run so that you may investigae the problem or try installing again." When I try to install from this desktop session, the install gets to the same point, the copying files box closes, and then just stops. The pointer is busy, the cd drive spins up occaisonally with no data transfer, no hard drive activity. When I boot from the CD and access the disk boot menu, the disk checks good, memory checks good ( I upgraded the original memory to 512 mb). I also updated the bios to the newest from Dell. This is an older L866r, but should meet the requirements.

• Putting Ubuntu Server on to a networked HDD

  - by SimplySimon

  Firstly, I know very little about servers and secondly the 1Tb HDD I have has network capabilities, but no software is installed on it, so when connected to the computer it is seen as a network connection, but not as a drive. Any advice on how to get started would be great. Up until now, I have been using it as a USB drive which worked well, but when this is sorted, I would like it to be connected directly to our BT HomeHub accessible through the WiFi for all the family to use as a film and back up repository. I would then be able to set up individual accounts for each family member to use and may be, if possible, make it accessible from outside locations. The First question then is: How can I install Ubuntu server on the 1Tb HDD attached directly to the computers network port but which doesn't show up in Nautilus? HDD Western Digital 1.0Tb LBA 1953525168 Model: WD10EACS-00DB0 DCM: DHRNHT2CF

• Installing along side of Windows 8

  - by Jake

  It appears as though many people are having problems installing Ubuntu along side Windows 8. My problem, however, seems to be sufficiently different to be unique among such problems. I can't get the Ubuntu 12.10 live-USB installer to run. When I boot I get the following four options: Run from this USB Install to disk Check memory (I can't remember the last one) I have tried the top two. Both result in the screen going black briefly then windows 8 booting as per usual. Does anyone know how I may manage to overcome this problem?

• Is it ethical for a programmer to promote his/her own library?

  - by Kit Menke

  Fairly recently I started maintaining my own open source JavaScript library. I created it to solve a pretty specific need but fairly regularly see questions that can be solved (in whole/part) by using my library. I've always gone ahead to post my answer including my library and make sure to always include a disclosure specifying that I maintain it. I feel for open source projects this may not be such a big deal but where do you draw the line? (ex: commercial products) Is it ethical for a programmer to promote is own library? When is it not?

• What languages do you support when localizing?

  - by Javoid

  I recently converted an iphone app to support different languages, and was wondering which ones I should include, and which ones aren't worth the trouble. What I mean by that is best illustrated by an example. In Ireland, the Irish language is spoken by very few of the people there. It could be considered a dying language. Almost everybody speaks English (if not everybody). So in this example, I don't think it's worth the trouble to support. In addition, the number of people using modern technology may be limited as well. For example, most people in Cambodia would not be likely to purchase software, and therefore the benefits of localization are reduced. What languages do you support when localizing?

• How to test 3d acceleration?

  - by HappyDeveloper

  I want to install and test 3d acceleration in Ubuntu 12. I have read these pages: https://help.ubuntu.com/community/RadeonDriver https://wiki.ubuntu.com/X/Troubleshooting/VideoDriverDetection?action=show&redirect=X%2FTroubleshooting%2FFglrxInteferesWithRadeonDriver#Problem:_Need_to_purge_-fglrx I think I have installed it correctly, but I don't know how to test it. I tried to play minecraft in the browser, but I got a black screen. It may be a java problem too, so I need to troubleshoot. So how can I test my video card and drivers?

• Can I use the test suite from an open source project to verify that my own 'compatible library' is compatible?

  - by Mark Booth

  The question Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project? makes me wonder what would be considered a clean-room implementation in the era of open source projects. Hypothetically, if I were to develop a library which duplicates the publicly documented interface of an open-source library, without ever looking at the source code for that library, could that code ever be considered a derivative work? Obviously it would need the same class hierarchy and method signatures, so that it could be a drop-in replacement - could that in itself, be enough to provoke a copyright claim? What about if I used the test suite of the open source project to verify whether my clean implementation behaved in the same way as the original library? Would using the test suite be enough to dirty my clean code? As should be expected from a question like this, I am not looking for specific legal advice, but looking to document experiences people may have had with this sort of issue.

• Touchpad stopped working out of the blue

  - by KI4JGT

  So, I'm watching "The Walking Dead" and all of the sudden I lose control of my mouse through the touchpad. At first it was just for my user. I could reboot my system and switch to another user and use it just fine. I cannot explain the steps I took (I'm using the keyboard to manuver firefox right now) but it was something along the lines of: sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps After this command, I regained control of my mouse but the computer didn't recognize it as a touchpad. I thought if I rebooted again, it may do the trick. So after I rebooted, the mouse went completely kaput. I cannot get the mouse to work at all now even though I've tried the command several times. I've tried different users and it's still the same.

• How do I make the correct career decision in regards to product manager/QA vs programmer?

  - by Adel

  I'm curious about how to approach the issue of whether I should focus on programming or on QA/testing/product management. I know that the latter seems like a broad category( if so, think of it as "general IT support" for now). At the moment I'm stronger in QA/prod. mgt ; however I'd like to switch more to programming, and I see I may have this opportunity. Wouldn't it be easier to switch to QA/prod. mgt in the future, if I go into programming now; rather than trying the reverse-order(i.e. if I decided later to go into coding.. say around mid-30s then it'd likely be harder). Just looking for any advice or tips about how to see more clearly. Part of me is scared I can't handle the programming side, but part of me says since there's demand and I'm interested that it's still worth a shot.

• Can Google Translate's audio files be used in a game?

  - by ashes999

  For my game, I need text-to-speech. Since it's Android, I decided to settle for MP3s, since the range of words spoken is few. For my prototype, I'm using Google Translate to generate the audio since it has awesome pronounciation across multiple languages. But can I use it in production? What if I sell my game for $1 on the app store? All I can find on SE is that the API may be LGPL, and that the licensing page mentions the API is only available for academic research -- nothing more. My usage is a bit different; I'm actually capturing the audio bits and using those instead. I'm curious to know the license for this; I can't find anything with my Google-fu.

• Do you use to third party companies to review your company's code?

  - by CodeToGlory

  I am looking to get the following - Basic code review to make sure they follow the guidelines imposed. Security code analysis to make sure there are no loopholes. No performance bottlenecks by doing a load test etc. We have lot of code coming in from third parties and is becoming laborious to manage code reviews and hence looking to see if others employ such practices. I understand that it may be a concern for some and would raise the question "Well, who is going to make sure the agency is doing their job right?" But basically I am just looking for a third party who can hold all vendor code to the same standards.

• As a indie, how to protect your game?

  - by user16829

  As a indie, you might not work in a company. And you may have a great game idea and you feel it gonna be a big success. When you released your game. How do you protect it as your own creation? So that someone also can't steal the title and publish a "sequel" e.g. Your-Game-Name 2,3,4. Or even produce by-products like Angry Birds but without your permission. So how we can prevent these from happening by legal methods. Like copyrights, trademarks? If a professional can fill us those info, it will be great.

• How to get rid of crawling errors due to the URL Encoded Slashes (%2F) problem in Apache

  - by user14198

  The Google web crawler has indexed a whole set of URLs with encoded slashes (%2F) for our site. I assume it has picked up the pages from our XML sitemap file. The problem is that the live pages will actually result in a failure because of the Url Encoded Slashes Problem in Apache. Some solutions are mentioned here We are implementing a 301 redirect scheme for all the error pages. This should make the Google bot delete the pages from the crawling errors (no more crashing pages). Does implementing the 301s require the pages to be "live"? In that case we may be forced to implement solution 1 in the article. The problem is that solution 1 will pose a security vulnerability..

• Is there a pattern or logical structure I can follow for Event Log Numbers?

  - by makerofthings7

  What are some ideas or structure I can use when assigning EventID to events that will be saved to the Event Log? Some options I've considered Sequential (0... int.Max) Multiple of 10, where the "0" is replaced with how noisy the debugLevel is set. xxx0 may represent exceptions, critical information, start, stop etc. ...? What numbering approach gives you the most insight when a user describes the event in an email or phone? What is the most useful to support staff?

• Is MochaHost as good as it sounds?

  - by gilly3

  It's time for me to find a new web host, and I'm a bit overwhelmed by the selection. I need a Windows host. One provider that seems to stand out is MochaHost. Here are a few of the things that look amazing to me: 2 free domains for life. 2!! MS SQL Support - Unlimited Databases 5,000 sites $3.33/month Unlimited everything (traffic, storage, domains, etc.) Is MochaHost too good to be true? Maybe it is notoriously unreliable (despite their 100% uptime guarantee)? Are there other considerations I may be forgetting?

• My laptop shuts down when I remove the charger

  - by Hakim0

  Laptop shuts down when charger is removed. As well I get a message when booting up saying disk drive for /media/3936-3939 is not ready or not present. About a week ago I was trying to install a matlab iso file using mount commands etc... I tried mount, fuseiso, and UNETbootin. I have a feeling this may have something to do with message I'm getting from booting up. If anyone can point me in the right direction or help me out. Many thanks.

• Ubuntu won't load properly all of a sudden

  - by Peter Raeves

  This has been the second time this has happened, but when I booted this morning my hardware wasn't detected anymore. I see both screens pop up as normal, choose Ubuntu 14.04 in the grub list and from that point onwards none of the following hardware seems to be used: VGA, DVI-D, USB, Audio jacks. This has happened before, but at that time, I still had one screen left, so I could navigate through the (non-USB) keyboard and how weird this may sound, but from the moment I opened Windows in vmware, all of my hardware started working again. This was a few weeks ago, but the same seems to have happened again. This time I can't use that little hack though, since now Ubuntu stops using both screens. My hardware is all detected, Ubuntu just doesn't want to use it somehow. Did anybody else encounter this and how did they solve this?

• Examples of Android Joystick Controls? [on hold]

  - by KRB

  I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

• Isometric tile range aquisition

  - by Steve

  I'm putting together an isometric engine and need to cull the tiles that aren't in the camera's current view. My tile coordinates go from left to right on the X and top to bottom on the Y with (0,0) being the top left corner. If I have access to say the top left, top right, bot left and bot right corner coordinates, is there a formula or something I could use to determine which tiles fall in range? I've linked a picture of the layout of the tiles for reference. If there isn't one, or there's a better way to determine which tiles are on screen and which to cull, I'm all ears and am grateful for any ideas. I've got a few other methods I may be able to try such as checking the position of the tile against a rectangle. I pretty much just need something quick. Thanks for giving this a read =)
