• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• What will be a good python script (or your favorite language goes here) to test a system's performance and capabilities?

  - by dassouki

  Let's say you're in a computer store looking at 10 laptops, you want to really compare the system's capabilities. What will be an efficient "your fav language goes here" script that will allow you to do this? As an example, when I go to the store I usually open a macbook and a pro's terminal and write an equation in python, iterate it a million or so times, and time them. I like to compare the difference in time. What would be an ideal and simple script that can efficiently compare systems?

• Wiped data, and duplicated folders into files.

  - by Kaustubh P

  Something weird happened today, and I dont know how. Within a folder, all folders have a file by the same name, with a colon appended to it. And all the files from the most inner-most directory in my home, have been dumped to ~, with a size of 0 bytes. I have not executed any scripts or anything. I was just checking out some easter eggs, namely the gegls from outer space and free the fish and was away from the computer and was logged because of the screensaver. I couldnt log-back in with my password, so I just reset the PC, and while booting, the PC went into a drive check. BUT, IIRC, i saw the duplicate "folder files" before I had logged out, so thats not the reason! All the files have a timestamp of 14 Jan. Also, the contents of my eclipse folder have been dumped into ~. Right down to the jars and ini files. HELP!

• How do I use a 4GB USB flash drive to install Ubuntu 12.10?

  - by Logan

  I've downloaded "ubuntu-12.10-desktop-amd64" and used Pen Drive Linux to get it onto my USB. I then restarted my computer (a Windows 7 Home Premium edition) and entered the boot menu to have it boot from the Sandisk USB (it called it Sandisk Cruzer Cruzer). Linux came up and asked if I wanted to try or install. I picked install, connected to my Wi-Fi, and installed it. After my laptop restarted, Windows booted immediately. I have tried several times and cannot get a choice between the two. P.S. I have used the Windows Installer, Wubi, but at the last second it gave me some kind of error.

• Bluetooth pairing works in 10.10 but not in 11.04

  - by Nathan Haines

  My laptop, a Compaq Presario V2000, has a built-in Bluetooth module that has worked well since at least Ubuntu 8.04 LTS. I use it to pair with headphones and a mouse. These both worked great in Ubuntu 10.10 (and still do with a live CD) but I cannot pair to any Bluetooth device in Ubuntu 11.04, even from a live CD. I can see the Bluetooth module in lspci and when I try to set up a new device from the Bluetooth indicator my computer detects all Bluetooth devices around me but pairing always fails. At the moment I'm most concerned with getting my Microsoft Wireless Notebook Presenter Mouse 8000 paired. Relevant output of lspci: Bus 003 Device 002: ID 03f0:011d Hewlett-Packard Integrated Bluetooth Module

• Falied installing ATI X.Org binary driver!! (ATI Radeon HD 5400)

  - by Naveen

  The open source driver worked well with the fresh installation of Ubuntu 12.04, but it drains my laptop battery faster. So I installed the proprietary driver from jockey-gtk. It gave me this error message at the end of the installation: Here is the jockey.log After restarting the computer, I lost all the compositing animations. Compiz visual effects don't work. There is a black boarder around Docky. Please somebody help me...! Thanks!

• My ASUS U32U with fresh Xubuntu install shows a black screen 50-80% of the startups

  - by Jona Ekenberg

  I have recently installed Ubuntu 12.10 with Xubuntu-package on my ASUS U32U notebook (Radeon HD 6320 GPU). The issue I have is that more often than not, after the GRUB-select screen I get a black screen, and three times total white lines (kind of) flashes very quickly (with maybe 5 seconds between each flash). I'm not even able to get to the login-screen (nor the Xubuntu loading screen). At first I thought it was simply me having installed something dumb or messed up some settings, but even after reformatting the partition and installing ubuntu again, the problem remains. Before I formatted it xfce4's window manager wouldn't start either, but it does now (when I am able to see anything). I can access the virual consoles (ctrl+alt+f1), but I can't see anything, but I've managed to shutdown the computer by using it (sudo shutdown -h now).

• How to install hardware drivers for my laptop

  - by John Flisk

  Everytime I change the OS I usually format my laptop. It is an HP tx-2 Touchsmart. It has a touchscreen and additional hardware that isn't working (i.e. volume control buttons and the network discovery) If I was on windows I would just download the hardware drivers from the HP website. How do I go about installing the software for the built-in hardware of my laptop? I am new to the community and I really want to get this computer working like it used to, to get the full Ubuntu experience. Please direct me, thank you.

• The Best How-To Geek Articles for June 2011

  - by Asian Angel

  June has been a busy month here at How-To Geek where we covered topics like cleaning keyboards, what to do when your e-mail has been compromised, creating high resolution Windows 7 icons, and more. Join us as we look back at the most popular articles from this past month. Note: Articles are listed as #10 through #1. What You Said: How Do You Keep Notes? Note taking applications have grown increasingly sophisticated. Historically, when people took notes on a computer they simply used the word processor or text editor installed on it and left it at that—mostly because there were few widely available alternatives. While many people still use simple txt files for their note taking needs an entire ecosystem of note taking apps exists now—thanks, in large part, to the rise of widespread internet access and easy synchronization.How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag?

• Why does qt-creator need to connect to google-analytics?

  - by Nanda

  I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

• Wrong notification on GNOME Shell?

  - by audrianore

  I just installed GNOME Shell on my 12.04 a couple hours ago. The notifications are just cool, and I installed shell extensions, and it works smoothly in 1 hour. Then I restarted my computer for some reason, start back in to GNOME. And I was surprised with the default notification showed up. It replaced the GNOME notifications! I tried to: Reinstall gnome-shell. (autoremove and install) Reset desktop configuration. But it didn't work at all. Is there anything I can do to fix it? Plus: I got a double notification (osd + gnome notification showed up) when someone chatted me.

• How to merge two .iso images

  - by pgrytdal

  I am following this tutorial to install Android onto my computer VIA Virtual Box. My problem is, they want you to download liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 then they want you to merge these two files with cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso in the Terminal. The problem is, when I run the command, I get the following output cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso cat: liveandroidv0.3.iso.001: No such file or directory cat: liveandroidv0.3.iso.002: No such file or directory So, I was wondering if there was an alternative way to merge these files? Or if you guy's could help me merge them this way? Extra info: OS: Ubuntu 12.10 I downloaded the files to my /downloads folder in my home directory.

• What is the simplest human readable configuration file format?

  - by Juha

  Current configuration file is as follows: mainwindow.title = 'test' mainwindow.position.x = 100 mainwindow.position.y = 200 mainwindow.button.label = 'apply' mainwindow.button.size.x = 100 mainwindow.button.size.y = 30 logger.datarate = 100 logger.enable = True logger.filename = './test.log' This is read with python to a nested dictionary: { 'mainwindow':{ 'button':{ 'label': {'value':'apply'}, ... }, 'logger':{ datarate: {'value': 100}, enable: {'value': True}, filename: {'value': './test.log'} }, ... } Is there a better way of doing this? The idea is to get XML type of behavior and avoid XML as long as possible. The end user is assumed almost totally computer illiterate and basically uses notepad and copy-paste. Thus the python standard "header + variables" type is considered too difficult. The dummy user edits the config file, able programmers handle the dictionaries. Nested dictionary is chosen for easy splitting (logger does not need or even cannot have/edit mainwindow parameters).

• Unity Desktop not loading and ccsm method not working

  - by slimy-spork

  I installed Ubuntu 13.04 x86_64 on my HP Pavillion DV7-6c60us. It installs fine and works until I update. I run the software updater and reboot as it requests after. When my computer comes back on I get the desktop background but the rest of the Unity desktop doesn't load. I've tried the ccsm method and re-enabling but it just de-enables itself. I've also tried installing the gnome desktop but that does nothing for me either. I really want to switch to Ubuntu but this is causing issues. P.S. I've also tried using 12.10 and 12.04 with no dice.

• Remote GDM login

  - by luri

  Is it possible to remotely (via ssh) make a login to GDM? I'll explain a situation in which I'd need this: I'm on my laptop and connect to my desktop via ssh. I realize there are some updates available. I install them all, but I need to reboot the computer. The problem is that once the desktop has rebooted, there will be no GDM session available, since it's necessary to log in. Can I somehow perform the GDM login remotely from my laptop? Edit: I can't find FreeNX for Maverick, and I haven't been able to configure x11vnc + vncviewer to work. Isn't there an easy way?

• Picture lens doesn't find anything

  - by Han Cnx

  I get Facebook results, but nothing from my computer. If I open a terminal and use 'locate' then I can find stuff, but the picture lens is empty. Note that my picture files are on an NTFS partition. I have made a link named 'Pictures' in my home folder that points to the location where the picture files are. Again, this works with the 'locate' command and it also works for the Music lens, which is also a link in my home folder. It also (kinda) works for the Video lens, though it only wants to find videos I have opened, which seems not consistent with the other lenses. (and also not very useful this way)

• Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

  - by user43816

  I just experienced an unusual crash: I tried to click on a name entry in the contact list of Empathy. A crash happened. Usually I am asked then if I'd like to report the error to Launchpad, and Launchpad opens. This time the error message was: "Excuse me. Ubuntu 12.04 noticed an internal error. If you notice further problems try to restart your computer. Send an error report to Launchpad to help removing this problem?" This time Launchpad did not open automatically. A new window opened and I could read the relevant error report. Later I found the error report in the file /var/crash/_usr_lib_empathy_empathy-chat.1000.crash. Why went the course of action this time differently from other crashes? Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?
