• Ubuntu 12.10 installation. Hit or miss Booting

  - by Robert

  I just recently downloaded and installed Ubuntu 12.10. I also completely wiped the laptop. The Ubuntu OS will only boot part of the time but never on the first time. Always, the first start up will automatically go to a purple screen and stay there. At first I waited for 45 minutes and nothing changed. Once I held down the power button to turn it off, I turned it back on to see the Asus screen followed by the grub menu. I can select "Ubuntu" and then there is a white box blinking in the top left corner. Then, it will either keep blinking or transfer to the Ubuntu loading screen(everything works fine if it gets to the loading screen). This has never happened before with prior versions of Ubuntu. Any ideas are helpful. Thanks!

• Where to go from here, how to improve / learn more

  - by bExplosion

  I finished University around 4 years ago double degree in Software Eng/Comp Sci. Got my first job at a startup in my final year, was with them for 2.5 years then started my own business. So far everything is going great, lots of clients and stead work etc, but coming right out of uni and into a start up I never had any form or senior software engineer guiding my work or suggesting improvements etc... Whats the best way for me to improve & learn more? Books? MS Exams? Other? I develop in C#, ASP.NET/MVC. Update The problem isn't really with releasing products, I've released quite a few which are up and running with customers happy. It's more with quality of code, best practices, how do I know something I am code is correct, it may work but there may be ways of coding it much more efficiently or by adhering to some kind of standard Cheers for any responses!

• Error after installing Lubuntu 14.04 through liveUSB

  - by Veritas

  A friend asked me to install ubuntu on his toshiba NB 200 netbook to replace windows xp. I formatted the flash drive, ran an nb5sum check on the iso and after running netbootin , I checked the drive for errors. No problems so far. During the installation, while everything seemed normal, the installation regularly paused until I pressed a button or moved the mouse. After restarting, it doesn't boot and it starts a shell showing : "General error mounting filesystems A maintenance shell will now be started CONTROL-D will terminate this shell and reboot the system " Any ideas? Any help is appreciated!

• How do I use Content.Load() with raw XML files?

  - by xnanewb

  I'm using the Content.Load() mechanism to load core game definitions from XML files. It works fine, though some definitions should be editable/moddable by the players. Since the content pipeline compiles everything into xnb files, that doesn't work for now. I've seen that the inbuild XNA Song content processor does create 2 files. 1 xnb file which contains meta data for the song and 1 wma file which contains the actual data. I've tried to rebuild that mechanism (so that the second file is the actual xml file), but for some reason I can't use the namespace which contains the IntermediateSerializer class to load the xml (obviously the namespace is only available in a content project?). How can I deploy raw, editable xml files and load them with Content.Load()?

• How should I structure a solution for a long term project?

  - by sooprise

  I'm about to create a do-everything dashboard for my team and am still having second thoughts about my project/solution structure. Since this could be a long ongoing project, I want to get the structure right from the beginning. This is what I had in mind: Create a solution named "doEverythingDashboard" Delete the project named "doEverythingDashboard" under the solution "doEverythingDashboard" Create winform project named "interface" Create console applications projects for each functionality of "doEverythingDashboard" Reference each console application in "interface" Does this make any sense? Would it make more sense to just have one project and create a class per functionality instead of an entire project?

• Application trying to use the wrong shared library

  - by Josh

  I'm having a problem with a program (quartus) running on my ubuntu machine. I'm getting the following error. quartus: symbol lookup error: /usr/lib/i386-linux-gnu/libXi.so: undefined symbol: XESetWireToEventCookie I have the correct libXi.so.6.0.0 file but no matter where I put it, the OS won't use it unless I apt-get remove libxi-dev, but a lot of software uses this libXi. What I want to do is add some sort of exception to the dynamic linker so that quartus uses the libXi.so that it needs and everything else still uses the one in /usr/lib/i386-linux-gnu. Thanks!

• Assemble static site from templates? (don't want to reinvent the wheel)

  - by raindog308

  I have a site that is 100% static content (no php, just some javascript). There's several "blocks" like the header, menu, footer, etc. that are the same on each page. Rather than do a lot of copy/pasting, I was thinking of some kind of template system where I could run a CLI command (in php, perl, python, shell, whatever) and have it replace all the block tags with the actual block text. I did see some answers in this question, but those seem oriented towards "we provide the style and layout, you provide the text". In my case, I have everything as far as layout, css, etc. - just want to do a glorified sed. Before I invent the wheel, I was wondering if there was a tool out there already.

• Wordpress does not create directories?

  - by Marcappuccino

  First I will just tell you how my wordpress hierarchy looks like: /var/www has all of the wordpress files, which is different from how it is normally set up as /var/www/wordpress (symlinked to /usr/share/wordpress). So var/www contains all of the files that /usr/share/wordpress would have, and /usr/share/wordpress is symlinked to /var/www, with an extra /var/www/wordpress symlinked to /var/www to prevent possible compatibility issues. When uploading a file like a favicon or a .zip-ped theme, everything works fine, and when checking if the theme/favicon is uploaded, wordpress shows that it is, and points to a directory that it thinks that it had created, like http:/localhost/wp-content/uploads/2012/..., which it had not, because the uploads folder is empty! And so there is a broken link on the internet and the theme is displayed but it has just plain text (because it had reverted to a plain theme I think) Please help! I am sorry for such a long post but this is really quite a troublesome problem. I have chowned /var/www and /usr/share/wordpress to www-data.

• How to fend off external interuptions?

  - by Demian Kasier

  I want to keep my focus at work, but I am constontly interupted. examples: - the boss asks something to the whole team. - a coleague asks something about a piece of code I wrote - something funny on the radio - smalltalk among coleages with a joke in between. - ... As extra info: We are a team of 6 developpers in one room, with sales and suits constantly coming over to ask and tell us things we must and mustn't do. So how do you keep you focus and attention to your work? so you can get some things done, instead of answering to everyone and everything that interupts you?

• What does it mean to "have experience with the Unix/Linux command line"? [closed]

  - by Aerovistae

  I'm a new comp sci grad applying to jobs, and this requirement confuses me, especially since the job description (Python back-end developer) says it's the single most important thing ("Everything else we can teach you!") I mean, I know how to use the command line... I know your standard run-of-the-mill stuff like navigating around and manipulating files and permissions and using pipes and running applications, but what are they looking for when they say something like that? I'm aware there's no end to what you can do with the command line, but I was under the impression that after a certain point it's the sort of thing that only benefits server/system administrators.

• How to flag a class as under development in Java

  - by Usavich

  I'm working on a internship project, but I have to leave before I can finish up everything. I have 1 class that is not stable enough for production use. I want to mark/flag this class so that other people will not accidentally use it in production. I have already put the notice in Javadoc, but that doesn't seem enough. Some compiler error or warning would be better. The code is organized like this: [Package] | company.foo.bar.myproject |-- Class1.java |-- Class2.java |-- Class3.java <--(not stable) If there was a single factory class that calls those classes in public methods, I could have set the method to class3 as private. However the API is NOT exposed that way. Users will directly use those class, e.g. new Class1();, but I can't make a top-level class private. What's the best practice to deal with this situation?

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• Can I upgrade Unity

  - by user208455

  Since the bug described here I am moving LTS distros only, however the current LTS is 12.04, and I`ve seen how ubuntu 13.10 looks like, I know that the unity interface is a WOP but, I wanna know is there any possible way to upgrade unity in 12.04? and btw, after that wipeout ,from the post I was reffering to, that sam stupid (to be polite) thing did windows xp, but now I have shortenned the 500GB ntfs partition to 100 GB and added a 100GB ubuntu partition (for /) and a 200+ GB partition for /home and installed ubuntu 12.04 like that (in "something else"). And after a few minor grub issues everything works perfectly, just like it should be

• Just installed 12.10 with WUBI and get error

  - by John

  Goes to the terminal screen and says: [drm:drm_crtc_helper_set_config] ERROR failed to set mode on 'crtc:10] From what I gather, this is an issue with my monitor. Not sure. I am really new to this. I have a Compaq Presario running XP SP3 and am using a Sony Bravia 32" LCD TV as a monitor. Downloaded Ubuntu from, well,... Ubuntu. Used WUBI to install. I suppose it created its own partition because install never asked. Is there a work-around for this? I have tried everything I know of, given my very limited experience. Thanks in advance.

• Ubuntu Desktop or Ubuntu Server?

  - by Twinborn

  Hello everyone. I'm new to Linux and Ubuntu is my first distribution. I have chosen Ubuntu because I want to learn more about Linux. I'm under time constraints and need to setup a server as soon as possible. I have Ubuntu Desktop and Ubuntu Server setup via VMWare Fusion on my MacBook Pro. I installed everything I need on the server edition, but it feels way over my head. I have no experience with CLI. Can I just use Ubuntu Desktop to run my Web server for the time being while I learn CLI? I basically need to run Apache, PHP, MySQL, phpMyAdmin, Python and Django. Should I be using MAMP? Thanks.

• What is the SEO-recommended method for using underscores and dashes in URLs that contain geographic locations?

  - by ElHaix

  In reading through this article: In Subfolder & File Names, Use Dashes, Not Underscores Good: Good: http://www.domain.com/sub-folder/file-name.htm Bad: http://www.domain.com/sub_folder/file_name.htm In my URL's, I may have one or two city names, ending with the province/state: Burnaby_New_Westminister-BC/[some search term]. My URL rules currently are defined such that everything after the dash is the prov/state. Some geographic locations already contain dashes: Notre-Dame-de-Grâce (in QC), which I would convert to ~/Notre_Dame_de_Grace-QC/ I thought of placing the prov/state after another "/", however in some cases the province/state name may not exist, thus ~/Notre_Dame_de_Grace/, so the first term after the domain name contains the geo location {city, city_name-state}. I am now revisiting this, and wondering if this rule set should change, and if so, what is the recommended way of implementing this? -- UPDATE -- After reviewing this video, I see that I should be using the dashes, rather than underscores. However since I still want to have my geo locations in the first URL section, is there anything wrong with using a double-dash separator - ie: /city-name--state/ ?

  After attempting to install Google Chrome i386 the installation failed. I then proceeded to the AMD64 to see if it was the problem but...... My computer froze and I forced shut down.

Solution anyone PS:Update manager does not work and I don't have Snyaptic. The file itself failed at the real real end and froze everything but the cursor.

• Creating an Interface To a Language's Standard Library?

  - by Nathan Arthur

  In the process of learning test-driven development, I've been introduced to dependency injection and the use of interfaces, and have started using these concepts in my own PHP code in order to make it more testable. There have been times when I've needed to test code that was doing things like calling the PHP time() function. In order to make these tests predictable, it seemed logical to create an interface to the standard PHP functions I use so that I can mock them out in my tests. Is this good software design? What are the pros and cons of doing this? I've found myself groaning at how quickly my PHP interface can stick its fingers into everything I do. Is there a better way to make code that relies on PHP-accessed state and functions more testable?

• What are the caveats of the event system built on Messenger rather than on classic .NET events?

  - by voroninp

  MVVM Light and PRISM offer messenger to implement event system. the approximate interface looks like the following one: interface Messanger { void Subscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(objec actionOwner); void Notify<TMessageParam>(TMessageParam param); } Now this model seems beneficial comparing to classic .net events. It works well with Dependency Injection. Actions are stored as weak references so memory leaks are avioded and unsubscribe is not a must. The only annoyance is the need to declare new TMessageParam for each specific message. But everything comes at a cost. And what I'm really worried about is that I see no shortcomings of this approach. Has anoyne the experience of some troubles with this design pattern?

• Database for Ubuntu

  - by Toby J

  I am trying Ubuntu 12.04 booted from a DVD disk before I install it. I currently havwe windows 8 (which I hate) and I have a couple of Data base programs with my movies, hundreds of movies, in them. Is there a database available for Ubuntu that is compatible with Microsoft Database? There are too much data in the current database file for me to have to rewrite the program. So far, I love the Ubuntu 12.04. I have been able to access my microsoft works spreadsheet files and documents with no problem. And I like the thuderbird email and just about everything else about Ubuntu 12.04. I just need to be able to access my database files and to write lables and envelopes. Thanks. Toby J Paris, TN

• Icons don't display for some application launchers

  - by Smk

  I am running Ubuntu 12.04 on my laptop for some time now. Since the first day only I have been facing the problem with icon images of some application not appearing up. It causes a lot of inconvenience in locating/identifying an application to be launched. I have updated my Ubuntu with the latest build today only but still the problem persists. I have googled around and tried everything relevant available out there but with no success. Please note that reinstalling Ubuntu is NOT an option right now.
