  • Mouse Problem on Ubuntu 12.10

    - by KashmirHackers
    I had a strange mouse problem on Ubuntu 12.10(64-Bit), the problem is that when I turnoff power supply/power goes off, the red laser light of my mouse also goes off and my mouse stops working but it works fine when A/C power supply is on. First I thought my mouse or my laptop's USB ports had problem but since I am using Dual Boot with windows 7, I checked my mouse on windows 7 and it works fine, even I turn off power supply. Today,I thought that I should give a try to Linux Mint 14-RC (which is based on same Ubuntu 12.10) and after installing linux mint when I plugged in my mouse it worked fine even though power is off. Don't know what is really going on, and I am afraid if I reinstall my Ubuntu 12.10 the problem will remain.

  • How to quantify product work in Resume?

    - by mob1lejunkie
    One of things I do in my Resume is try to quantify the impact my work has had in the particular company I was with at the time. The reason is it shows the value my work had added to the business. Is this what you guys do as well or am I the only one? In my previous job this was easy as I worked on short/medium internal applications and it was fairly easy to measure end result. For example, external consulting company quoted $50,000 for an application Business Services department wanted I completed it in 3 days so I say I saved the company $48,000. I have been in my current job for 3 years but all of it has been on 1 single well established product. About 30% work is maintenance and 70% work is on new modules. I have worked on various modules like API (WCF), Security (2 factor authentication), etc. How should I quantify work on modules? Many thanks.

    - by kindahero
    I downloaded 12.04 64bit, I checked with md5. Seems okay. made bootable usb with usb creater. Now if try to boot up from live usb. I just get "boot error". Nothing else. nothing else. googled around. nothing comes out. UPDATE: some additional info. The usb manufacture is sony. it is fat32 partitioned. Most importantly I could install 12.04 on other systems by same usb. Yes, I definitely setup my Bios boot order to look for USB disk first.

  • JavaFX 2.1.1 Documentation

    - by NancyH
    JavaFX 2.1.1 released on June 12, and few documents were updated on the docs.oracle.com/javafx website. Besides a new set of release documentation, the Concurrency in JavaFX article was updated with a discussion of how to cancel a task, with a code sample to illustrate that. A new section describes the WorkerStateEvent class and how to use the convenience methods such as cancelled, failed, running, scheduled, and succeeded, which are invoked when the Worker implementation state changes. Other documents were updated to reflect minor bug fixes, many of them contributed by JavaFX readers using the feedback alias in the sidebar of all of our documentation. Yes, we do respond and pay attention to what you say and at least try to point you in the right direction if we can't solve a problem you're having with a tutorial. We appreciate your feedback!

  • How to safely and painlessly switch from Kubuntu to Lubuntu?

    - by cdshines
    I've had Kubuntu installed for several years, updating from one major release to another, and now I think I'd like to try to switch to Lubuntu. But since my distribution is already tuned and shaped to satisfy my needs, I'd like not to get a fresh installation, but just purge kubuntu-desktop and install lubuntu-desktop. But when I execute sudo apt-get install lubuntu-desktop, it gives me an error of the following essence: The following packages have unmet dependencies: lubuntu-desktop : Depends: usb-modeswitch but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I investigate the modeswitch problem and get The following packages have unmet dependencies: usb-modeswitch : Depends: usb-modeswitch-data (>= 20110227-1~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. But: Reading state information... Done usb-modeswitch-data is already the newest version. So, my question is: what actions should I take in order to obtain a clean and fresh installation of Lubuntu? And also, how do I safely remove all the kubuntu-desktop-related stuff?

  • Does anyone have a good example/sample of "goto" spaghetti code? [closed]

    - by ArtB
    I've read a lot about how GoTo was considered harmful and removed for other control structures that were more intuitive. Does anyone have a good example / sample of goto spaghetti code? Preferrably, the sample code should be difficult to follow, but realtively easy when rewritten into more conventional control structures. I know I could try to write you some of my own, but I've never really used goto and don't think I could due justice to the headaches its abuse can lead to. I want this for didactic purposes to train junior developers on what to avoid. Mainly, to point to illustrate how OOP is taking the same idea to next logical consequence. EDIT: by good example I mean code that is terrible to read and abuses it, rather than code that uses goto for reasonable optimization

  • How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

    - by Mmmm
    I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

  • how to find 3g modem signal strength with out AT commands?

    - by neckTwi
    when i try to find signal strength of my modem using AT+CSQ, the usb device is locked by the network manager. To find the signal strength with AT+CSQ i have to first disable network connection using #nmcli nm wwan off to unlock the device inode /dev/ttyUSBX. Is there any nmcli option to get signal strength or any other option? EDIT The gdbus object for NetworkManager don't have any method like getSignalStrength. Network manager is locking device file preventing to use AT commands. nm-applet was able to display signal strength in system tray. so there should be a way to get signal strength form network manager! nmcli is command line counter part of nm-applet. Can i get signal strength using nmcli? nothing about signal strength is mentioned in its man pages.

  • Ubuntu multiple issues (blank screen)

    - by Donavon
    Computer Specs I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there. If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like: bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1) I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black. I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it. Any help would be GREATLY appreciated. Thank you

  • DHCP won't start / subnetting

    - by user114371
    I recently changed the IP address on an Ubuntu 12.04 server I have in my lab, which is running isc-dhcp-server. After doing so and modifying the dhcpd.conf file, my dhcp service would not start. I basically used the same configuration, except I modified everything to use /25 scopes rather than /24. When I try to start / restart the service, I see the following: MY@ubuntuserver:~$ sudo service isc-dhcp-server restart stop: Unknown instance: isc-dhcp-server start/running, process 20918 It looks like it starts, but it isn't actually running and Webmin states that the DHCP service is not running. So my question is, does isc-dhcp-server support subnetting (CIDR) style scopes, or must they be class A / B / C scopes (doesn't seem likely)? I've double checked the interface reference (this is a VM with only one defined eth0 interface) and everything else I can thing of.

  • Framework for Everything - Where to begin? [Longer post]

    - by SquaredSoft
    Back story of this question, feel free to skip down for the specific question Hello, I've been very interested in the idea of abstract programming the last few years. I've made about 30 attempts at creating a piece of software that is capable of almost anything you throw at it. I've undertook some attempts at this that have taken upwards of a year, while getting close, never releasing it beyond my compiler. This has been something I've always tried wrapping my head around, and something is always missing. With the title, I'm sure you're assuming, "Yes of course you noob! You can't account for everything!" To which I have to reply, "Why not?" To give you some background into what I'm talking about, this all started with doing maybe a shade of gray hat SEO software. I found myself constantly having to create similar, but slightly different sets of code. I've gone through as many iterations of way to communicate on http as the universe has particles. "How many times am I going to have to write this multi-threaded class?" is something I found myself asking a lot. Sure, I could create a class library, and just work with that, but I always felt I could optimize what I had, which often was a large undertaking and typically involved frequent use of the CRTL+A keyboard shortcut, mixed with the delete button. It dawned on me that it was time to invest in a plugin system. This would allow me to simply add snippets of code. as time went on, and I could subversion stuff out, and distribute small chunks of code, rather than something that encompasses only a specific function or design. This comes with its own complexity, of course, and by the time I had finished the software scope for this addition, it hit me that I would want to add to everything in the software, not just a new http method, or automation code for a specific website. Great, we're getting more abstract. However, the software that I have in my mind comes down to a quite a few questions regarding its execution. I have to have some parameters to what I am going to do. After writing what the perfect software would do in my mind, I came up with this as a list of requirements: Should be able to use networking A "Macro" or "Expression system" which would allow people to do something like : =First(=ParseToList(=GetUrl("http://www.google.com?q=helloworld!"), Template.Google)) Multithreaded Able to add UI elements through some type of XML -- People can make their own addons etc. Can use third party API through the plugins, such as Microsoft CRM, Exchange, etc. This would allow the software to essentially be used for everything. Really, any task you wish to automate, in a simple way. Making the UI was as also extremely hard. How do you do all of this? Its very difficult. So my question: With so many attempts at this, I'm out of ideas how to successfully complete this. I have a very specific idea in my mind, but I keep failing to execute it. I'm a self taught programmer. I've been doing it for years, and work professionally in it, but I've never encountered something that would be as complex and in-depth as a system which essentially does everything. Where would you start? What are the best practices for design? How can I avoid constantly having to go back and optimize my software. What can I do to generalize this and draw everything out to completion. These are things I struggle with. P.s., I'm using c# as my main language. I feel like in this example, I might be hitting the outer limit of the language, although, I don't know if that is the case, or if I'm just a bad programmer. Thanks for your time.

  • what is the purpose of arrows?

    - by Simon
    I am learning functionnal programming with Haskell, and I try to grab concepts by first understanding why do I need them. I would like to know the goal of arrows in functional programming languages. What problem do they solve? I checked http://en.wikibooks.org/wiki/Haskell/Understanding_arrows and http://www.cse.chalmers.se/~rjmh/afp-arrows.pdf. All I understand is that they are used to describe graphs for computations, and that they allow easier point free style coding. The article assume that point free style is generally easier to understand and to write. This seems quite subjective to me. In another article (http://en.wikibooks.org/wiki/Haskell/StephensArrowTutorial#Hangman:_Main_program), a hangman game is implemented, but I cannot see how arrows makes this implementation natural. I could find a lot of papers describing the concept, but nothing about the motivation. What I am missing?

  • Why does the sudo command not work in chroot?

    - by katarina
    I just installed a 32-bit chroot to run on my 64-bit system. In the chroot environment, the sudo command doesn't work, it says sudo: command not found Also, when I try the su root command, my password doesn't work (su: authentication failure). What password do they want? I'm quite new to Ubuntu, so actually I don't really know what I'm doing. I am just trying to follow instructions. I solved this particular problem simply by starting the chroot by the command: katarina@ubuntu:~$ schroot -c oneiric_i386 -u root instead of the one I used the first time: katarina@ubuntu:~$ schroot -a I still have some other problems, but I guess that's not for this question.

  • NetBeans "Find Usages" Tool Integrates JSF Expression Language

    - by Geertjan
    I saw this by Adam on Twitter today: Interesting. Let's try it. Here's my method "getCustomerId". I select it, right-click, and choose "Find Usages" (or press Alt-F7): A nice dialog appears: Then click "Find" and, guess what, this is what I see (click to enlarge it): Clearly, as you can see, I'm not only finding the Java controller class where the getter is used, but also the Facelets files, and, within those, the exact lines where the JSF expression language makes use of the getter. This is not a new feature, tried it and got the same result in 7.1.1, but it's really cool to know about nonetheless.

  • Why Firefox caching work will reset in version 3 but version 16 don't?

    - by huahsin68
    I am developing a web application and have the app deployed into Tomcat server. Tested on IE and Firefox and are working fine. Meaning when I close the browser and reopen the app, the data will be reset. When deploy to Websphere, the data is reset only in IE but Firefox don't. Meaning Firefox will cache the old data. I did try to clear the cache in FF but still failed. I did a test in FF3 and FF16, FF3 will reset the value but FF16 doesn't, I am just so curious why this could happened? Now I don't know whether this is my code problem or is actually the FF caching problem. Any clue on this?

  • Configuring Network without Default Gateway

    - by Homayoon
    I'm trying to connect my desktop and laptop using an ethernet connection. I usually configure network from the command line but this time I decided to give Network Manager a try, so I went to Network Connections, and selected manual IP configuration. At first I left the default gateway field blank, since I don't need a default gateway. Turned out network manager doesn't let me save the connection unless I enter that field, but entering a phony gateway messes up with my Internet connection. Anyway to do this setup?

  • Wireless very slow. Changed mode from Infracstructure to Ad-hoc

    - by Dan
    This is my first time using Linux so go easy on me :) I downloaded and installed Mint 11 couple of days ago and I was having trouble connecting to internet with wifi. Actually it says it connects but does not load any webpages. I tried to get help from this model of laptop owners (Asus G73SW) who uses mostly Ubuntu but they said they never had any problem right from install. So I decided to try out Ubuntu 11.04. Same thing. BUT now I get internet after going into Network Connection edit and changing the Mode from Infracstructure to Ad-Hoc. I get load pages but very slow. And if I'm not mistaken, as I was writing this paragraph, I might have been disconnected. However the wifi bar is full. Please help me this newb because I really want to keep using Ubuntu but I might just have to go back to W7 if nothing can be done. Thank you!

  • How to print with PYGTK on quickly

    - by user88476
    I am trying to make a program that can open save and print texts with Quickly, but I can't get the printing part to work. In my code when you press the "printbutton" it opens a print dialog: def on_printbutton_clicked(self,widget): self.printdialog.show() and that works fine. And when you click "ok" it will gather the settings from the dialog and try to print: def on_printdialog_response(self,widget,ok): printjob = gtkunixprint.PrintJob(self.filename,self.printdialog.get_selected_printer,self.printdialog.get_setting,self.printdialog.get_page_setup) but when I run it doesn't work and just gives me this: NameError: global name 'gtkunixprint' is not defined Is "gtkunixprint" wrong? Or is it something else in my code? Or should I first import something? I hope you can help me.
