  • At what point does programming become a useful skill?

    - by Elip
    This is probably a very difficult question to answer, because of its subjectivity, but even a vague guess would help me out: Now that Khan Academy is beginning to offer Computer Science lectures I'm getting an itch to learn programming again. I maybe am a bit more technical than your average computer user, using Ubuntu as my OS, LaTeX for writing and I know some small tricks like regular expressions or boolean search for google. However from my previous attempts to learn programming, I realized I do not have a natural aptitude for it and I also don't seem to enjoy the process. But I am fairly certain that a basic proficiency in programming could prove to be very beneficial for me career wise; I also often get ideas for little scripts that I cannot implement. My question is: Let's say you study programming 1 hour / day on average. At what point will you become good enough so that programming can be used for automating tasks and actually saving time? Do you think programming is worth picking up if you never have the ambition to make it your career or even your hobby, but use it strictly for utility purposes?

  • How to get a list of installed software packages? [closed]

    - by mblaettermann
    Possible Duplicate: How to list all installed packages? I am on a "grown" system. My initial setup was using Ubuntu 9.04. But now with the 12.04 Update I got stuck. My System is freezing or wired errors occour. I want to reinstall my system on a clean partition. How can I get a list of the packages I installed in my system? I want a list with the base packages not all the dependecies, so I can install all packages on my clean install again with the correct (maybe new) dependencies. I other words: I want to retrieve a list of all packages installed with apt-get directly. Not the ones it additionally installs with these packages. Thanks!

  • Edubuntu boot problem on dual boot PC

    - by trptplyr
    When booting Edubuntu on a dual boot PC with Windows 7, the last message that I get is "Restoring resolver state" [Ok]. I then press the Enter key, some other messages come up and go away too quickly to notice what they say, and then the system shuts down. Windows 7 works fine. My system is an older Dell Inspiron 9400 laptop with 3Gb usable memory. This all started happening after attempting to upgrade to the next version of Edubuntu, but was not allowed to because I didn't have enough space in my partition to allow for it. I'm unsure whether that has anything to do with the problem.

    - by benonsoftware
    Well first I would like to add at the moment I have had 1174 page views. That does not count people who just browse via the homepage so add around another 200 visitors! Well back on the subject I have recently joined Ubuntu-AU (Australia) LoCo team and it is great! Basilar it is a Ubuntu loco community group and just before the my first time being at a meeting I was emailing the admin and he said that there was a stop for a team reporter and I put my hand up and he said 'yes'. He was actually going to ask at the team meeting I would have said no way! But because I saw it before hand and I asked him I wanted to do it. If you live in Australia consider join Ubuntu-AU they also have a Launchpad team.

  • How to revert to 10.04

    - by Keith Mastin
    Since "upgrading" to 12.10, the multitude of problems and slowness has wondering me , if I'm running windows, so I want to take it back to 10.04. Just some of the problems that we never had in 10.4: Can't play YouTube and chat at same time; Can't open more than 5 photos in GIMP without constant grayouts; Can't easily close apps or programs on desktop; Can't Use Avidimux and Audacity at same time, CPU load stays at 100%; New Gnome is not nearly as intuitive as classic, focus is all over the place, have to constantly switch to have the focus on right window of same program (either browser), etc. Do I need to wipe my system partition and start over, or is there an easier way to downgrade?

  • Move a player to another team, with players stored in one arraylist and teams in another using java

    - by user1056758
    Basically I have a team class, which has an array list that store the players in. In the driver class theres an arraylist that stores the teams. Anyhow I've worked out how to add a player to a specific team and like wise remove a player from said team. Where I'm hitting problems is when I try to transfer one player to another. My understanding is to scan through the first team,and get the player. Then some how add this player to another, by scanning through the chosen team and add to it? I've tried this way but it seems to replace the original player with the new player in both teams. My other approach would be to somehow return the parameters of the player object, create another with the return parameters, remove the orignal then add the new instance in the other team? Really not quite generally how I can go about this, been trying all afternoon! If someone could offer me a general idea, then I can go off and apply the understanding to practice. Many thanks

  • Daemon for moving files between partitions?

    - by RATHI
    I have a system with Ubuntu installed in 20GB and windows in 100 GB, two partitions - each of 100GB using NTFS. While using DC++ (multiple downloading of big file) I used to get message that system is running out of memory. Is there any way to make a deamon which will be checking the Ubuntu partition so that if its used space goes up to a certain amount (let's say 18 GB) it will automatically start a moving file from this drive to another drive (let's assume it will pick the file from movie folder or largest media file from this drive to move)? Or it prompt to ask from user which file to move? Is there any program which can do this for me? If not, can you suggest something to read so that I could make it?

  • Which software should I use on Ubuntu to create a Windows XP LiveUSB? [closed]

    - by user92241
    Possible Duplicate: How to create Windows XP LiveUSB using Ubuntu to replace it Since many programs that I need only work on XP, I need to install Windows XP on my 2 laptops but I can't use an optical drive, which makes using a USB the only option. If it helps, I can tell you that I used to have Vista and Windows 7 on my 2 laptops but I clean installed Ubuntu 12.04 on one, and Lubuntu on the other. Also I have no trace of Windows left on any of my laptops, when I bought my laptops they came without a Windows CD, so I only had a 20GB partition on my hard drives (which I formatted when I clean installed Ubuntu and Lubuntu.) Also, I have no problem with clean installing Windows XP and the reinstalling Ubuntu/Lubuntu so I can dual boot. Thanks! Edit: I have a ISO file ready, on a USB.

  • Connecting to a Windows SVN server from Ubuntu

    - by skytreader
    I need to access an SVN repo hosted on a Windows machine from Ubuntu. However, even if I supply the proper credentials, it denies me access, apparently because Windows does not allow Linux connections (as they told me); sure enough, I got in when I tried to checkout from my XP partition. While I have my box dual-booted, it is inconvenient to switch just for SVN. So, does anyone know how I can access that SVN repo from Ubuntu? I've tried installing TortoiseSVN and Windows Subversion under Wine but I can't even get them to run; they were asking for some DLLs that I don't know how to supply. I've thought of installing a virtual XP just for SVN but I consider that too extreme and I'd be glad if anyone can advise a simpler workaround.

  • Speaking at SharePoint Saturday Cincinnati

    - by Enrique Lima
    I will be not only attending SPS Cincinnati, but also speaking. And I am very happy and excited about it! The topic: The difference between learning and training: Creating a SharePoint based Learning Management System The description: Training and learning have been defined as synonyms by many organizations. The difference is, training has focused on a classic and traditional model. Learning on the other hand, refers to achieving something from the receiving side of the story, not just delivery. In focusing on driving adoption it is important to have a strategy where learning is also part of the plan. This session focuses on how to create a SharePoint Learning Plan, and how to deliver the plan through the implementation of a Learning Management System. Come join us! More information about SharePoint Saturday Cincinnati can be found here: http://sharepointsaturday.org/cincinnati/default.aspx

  • How to recover disk and files after 10.04 boot failure?

    - by K R Jawaharlal
    I have a 1TB HDD with four Windows XP partitions and a 120GB HDD with 10.04. While working in Ubuntu, due to delay and failure to shutdown, I switched off the system. Next it failed to boot in Ubuntu and stopped at initramfs. After that, I tried to repair from the booting stage. By mistake instead of hdd no I used partition no. This damaged the Windows also. Then Windows XP was reloaded and is running. When I boot with 12.04, it is able to detect the 120GB HDD, but, it is unable to mount. I am unable to access the files. I would like to revive the disk and recover files. Would appreciate any help.

  • How do I install ubuntu 12.04 over windows HP

    - by Cakemix
    I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

  • Ubuntu 10.10 screen goes nuts and unreadable

    - by ChazD
    Running Ubuntu 10.10 in its own partition, also have Oracle Virtualbox 4 with Windows XP. Because i previously had a problem with a dark screen when i let the laptop on and i didn't use it for a long while i had set Power settings to Never sleep, never let the Display sleep. Monitor on install set to Laptop resolution 1400 by 1050, refresh rate 60 Hz, rotation Normal. The problem was when the computer was left on and i returned after about an hour, the screen was unreadable, similar to what used to happen to graphics cards before multisync became normal. So it appears as though the graphics card was asked to use a resolution it couldn't handle and went nuts. I had to power off the system, on restart everything was fine. Thanks for any suggestions.

  • Why does Windows 7 overall performance is better than Ubuntu 11.10?

    - by user37805
    I have a i7 2600 processor, 8Gb DDR3 ram, nVidia GTX570, and Ubuntu takes 45-50 seconds to boot and 32-35 seconds to power off, while windows 7 boots in 20-25 seconds and shuts down in 10 seconds. Both OS with autologin enabled, and in dual boot. Ubuntu is slow with preload too, and doesn't show any boot splash after installing drivers and didn't recognize my nVidia graphics card on jockey GTK, I had to add x swat repository and that didn't worked. I installed proprietary drivers through terminal (nvidia-common, nvidia-settings) in order to have 3d acceleration. But it doesn't make any difference on the speed. I also have a Pentium 4 PC and ubuntu 11.10 is way faster than windows 7 or XP. Also with nvidia graphics card and preload. http://paste.ubuntu.com/924890/ there is my boot script, sorry but some words are in Spanish because my ubuntu is in Spanish. Not using WUBI, Ubuntu has its own partition, 64-bits, and Matlab 2011 has very low performance compared to windows version.

    - by rowntreerob
    how do i get USB install of 12.04 installed? how do i change the BIOS? how do i partition the disk for dual boot? Web instructions for USB ISO bootable image were confusing. Series 9 has new, UEFI compatible BIOS - there is a gotcha involving "fast BIOS Mode" The native windows install included 2 partitions that were hard to get rid of: 21GB NTFS for "Samsung-rec" ... recovery 8GB for Hibernation both of the above were hard to get rid of in windows.

  • Gone in 60 Seconds: An Insecure Database is an Easy Target

    - by Troy Kitch
    According to the recent Verizon Data Breach Investigations Report, 98% of breached data originates from database servers and nearly half are compromised in less than a minute! Almost all victims are not even aware of a breach until a third party notifies them and nearly all breaches could have been avoided through the use of basic controls. Join us for this November 28th webcast to learn more about the evolving threats to databases that have resulted in over 1 billion stolen records. Also, hear how organizations can mitigate risks by adopting a defense-in-depth strategy that focuses on basic controls to secure data at the source - the database. There's no turning back the clock on stolen data, but you can put in place controls to ensure your organization won't be the next headline. Note, this webcast will be recorded for on-demand access after November 28th.

  • Installing ubuntu 12.04 LTS alongwith windows xp in two different HDDs

    - by chachu
    I have two HDDs. First HDD has four partitions with Windows XP in the first partition Second has two partitions and 15GB unallocated space. I tried to install Ubuntu 12.04 LTS in the second HDD by using Unallocated space. I tried for 6 times. Each time it got installed, but after first restart, it directly boots Windows XP in the first HDD and no boot options appear. Every time I found that the Ubuntu installation used unallocated space and made two partitions one EXT3 and other Linux swap. I don't know what went wrong. During Installation, Ubuntu detected Windows XP. Can anybody help me?

  • How do I restore GRUB 2?

    - by uahug
    I upgraded my laptop with an SSD, moving my old HDD to where the DVD-drive was, so that I could have speed and storage. Now, I have reinstalled Ubuntu on the SSD, deleting all the partitions on the old HDD to make space for a data partition. But now the laptop doesn't even get to GRUB 2 if the HDD is plugged in! If I take it out, everything works, but as soon as I plug it in and retry to boot, I won't find GRUB. At first, I thought it was because of the boot order, but the order was OK: first the notebook hard drive (SSD) and then the CD/DVD drive (which in reality is the HDD). How can I fix it? Doing a simple grub-install /dev/sda doesn't work.. The SSD is sda, and the HDD is sdb.

  • Bikeshedding: Placeholders in strings

    - by dotancohen
    I find that I sometimes use placeholders in strings, like this: $ cat example-apache <VirtualHost *:80> ServerName ##DOMAIN_NAME## ServerAlias www.##DOMAIN_NAME## DocumentRoot /var/www/##DOMAIN_NAME##/public_html </VirtualHost> Now I am sure that it is a minor issue if the placeholder is ##DOMAIN_NAME##, !!DOMAIN_NAME!!, {{DOMAIN_NAME}}, or some other variant. However, I now need to standardize with other developers on a project, and we all have a vested interest in having our own placeholder format made standard in the organization. Are there any good reasons for choosing any of these, or others? I am trying to quantify these considerations: Aesthetics and usability. For example, __dict__ may be hard to read as we don't know how many underscores are in there. Compatibility. Will some language try to do something funny with {} syntax in a string (such as PHP does with "Welcome to {$siteName} today!")? Actually, I know that PHP and Python won't, but others? Will a C++ preprocessor choke on ## format? If I need to store the value in some SQL engine, will it not consider something a comment? Any other pitfalls to be wary of? Maintainability. Will the new guy mistake ##SOME_PLACEHOLDER## as a language construct? The unknown. Surely the wise folk here will think of other aspects of this decision that I have not thought of. I might be bikeshedding this, but if there are real issues that might be lurking then I would certainly like to know about them before mandating that our developers adhere to a potentially-problematic convention.

  • How can I install Ubuntu alongside Fedora?

    - by user285248
    I am currently running Fedora and would like to duel boot with Ubuntu. I do not want to replace Fedora, I would like to keep it as my main OS. However, when using the Ubuntu installer I only get the option to either: "Replace Fedora release 20 (Heisenbug) with Ubuntu" or "Something else" Is there I way I can install ubuntu alongside Fedora without deleting it? If so, as I would like fedora to be my main OS, is there also a way to make it the top grub option? I have tried partitioning with gparted however I can't split the fedora partition, it says it is all used however I have only used about 100/500GB. I am trying to install ubuntu 13.10 off a live USB stick, I will upgrade to 14.04 when I install it but don't want to make a new live USB.
