• I'm trying to install postgresql on 12.04, and it's just not working

  - by Pointy

  I've got a new installation and I'm trying to get Postgresql working. The database was installed and I started a restoration from a dump on another machine, but that ran into problems because I had forgotten to install the "contrib" package. I used "pg_dropcluster" to drop the old cluster so I could start from scratch, and that's when things went weird. The first manifestation of this was that /etc/postgresql was just empty. I uninstalled the postgresql package and reinstalled, several times, to no avail. Is there something I can do to figure out why apt is confused here? I've done this many times on many systems and never seen anything like this happen.

• Meta Refresh for change of page name and content

  - by user3507399

  Hopefully just a quick one. I've got a client that is changing the name of a workshop that they run. This means a change of url, page title for keywords that they have first page ranking on. The keywords are still relevant so what I want to avoid is a 301 redirect to a page that has different keywords to the previous page. Is the best option to keep the old page live with url and title and use a meta refresh to redirect after a period of time (not instant)? That way the SEO ranking is retained for the previous workshop name while they work on the ranking for the name change? Would a 301 redirect have an inverse effect? Thanks!

• Accidentally hit shortcut and lost text in web browser. Can it be disabled?

  - by uniomni

  I have noticed that I occasionally hit some shortcut while typing that either kills the browser or otherwise causes me to lose e.g. a post I am writing. This typically happens if I type while on a bumpy road or something like that. It also just happened to my eight year old daughter ;-( I think the shortcut in question is CTRL-w which (at least in Firefox) closes the current tab and consequently whatever content is being written. I would like to know if anyone has noticed this and if someone has a solution e.g. a way to disable "dangerous" shortcuts if at all possible. Many thanks Ole (uniomni)

• Are there any alternative JS ports of Box2D?

  - by Petteri Hietavirta

  I have been thinking about creating a top down 2D car game for HTML5. For my first game I wrote the physics and collisions my self but for this one I would like to use some ready made library. I found out Box2D and its JS port. http://box2d-js.sourceforge.net It seems to be quite old port, made in 2008. Is it lacking many features of current Box2D or does it have major issues with it? And are there any alternatives for it?

• Are there any advantages to using ASP.Net MVC 3 over Ruby On Rails for existing businesses? [closed]

  - by user786621

  Possible Duplicate: What ASP.NET MVC can do and Ruby on Rails can't? I've been hearing a lot of good press about Ruby On Rails but I'm having a hard time finding much information on the advantages of using ASP.Net MVC 3 over RoR, yet I see many existing businesses migrating over to ASP.Net MVC. Does ASP.Net MVC 3 have any advantages over Ruby On Rails for existing businesses such as possibly tying into old databases better or allowing for more complex business logic? Or is it most likely the case that they are transferring simply because they were already using ASP.Net for Winforms?

• Some help understanding and modifying a 2D shader

  - by electroflame

  I have a similar question as the one posed here, except that I don't wish to use a 1D Color Palette. I simply wish to have it display 1 color of my choosing (red, for example). I plan to use this as a "shield" effect for a 2D ship. I also wish to understand how it works a little bit better, as I'll be the first to admit that shaders in general are not my strongest suit. I'm not asking for an overview of HLSL (as that is too broad of a subject), just an explanation of how this shader works, and the best way to implement it in a 2D game. Code examples would be ideal (even if they are theoretical) but if the answer is explained well enough, I might be able to manage with plain old text. This is also in XNA 4.0. Thanks in advance.

• How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

  - by max

  I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?

• A Virtual(Box) Christmas!

  - by Gilles Gravier

  Hello and merry Christmas everybody!Yes. This year, it's a v4.0 Xmas! VirtualBox just came out with a new major version release. Version 4.0 is available at : http://www.virtualbox.org/wiki/Downloads ... and of course, it's open source, and it's free. And I suggest (strongly) that you also download the free Extension Pack from the same page... Brings USB 2.0 emulation and more!I upgraded the version on my Solaris Express (get that from : http://www.oracle.com/solaris/index.html and follow the Download Solaris Express link on the right) laptop (pfexec pkgrm SUNWvbox and then pfexec pkgadd -d the .pkg in the compressed archive file, and install the extensions from the VBox GUI once it's launched). If you are on an old fashion OS without proper RBAC, replace pfexec by sudo. Which you can also do on Solaris if you really want to. :)I tell you, it's Christmas, for sure!Merry VBox!Gilles.

• 301 re-direct all external links to new domain

  - by Dean Legg

  I have changed the main domain to a sub-domain & would like to re-direct all external links to the new sub domain. Have read a few articles but having no luck editing the .htaccess as it might be interfering with all the rules in there. Old: www.example.co.uk New: https://secure.example.co.uk The current rules are quite handy because it seems to have sorted out the structure for all internal links. It has even updated the file path for images (or this could just be wordpress as the url was updated under general settings). This is the current .htaccess <files wp-config.php> order allow,deny deny from all </files> # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress

• HP DL360 G4 screen resolution problem

  - by dogmatic69

  I just bought an old blade server to mess about with at home and cant get the thing to work. I have run the installer 11.10 x64 server and that was fine. After installing and rebooting, POST is fine but when grub kicks in the screen shows a popup type box complaining that it cant use the resolution. I have tried different screens and its always the same. I can reboot and go back into the installer and the screen is fine. I tried to follow some guides on-line about changing the resolution but I cant get a terminal. I found one in the installer but that is using the ram as /. the installer says 'the drive is mounted as "/target"' but I don't see that, nor /mnt/target. Could anyone help me configure this and get it running. Thanks.

• "Failed to fetch" while updating

  I'm trying to update from ubuntu 12.10 lately but I keep getting the "Failed to fetch" error.

• How relevant is PHP today for browser games?

  - by Bitgarden

  I was the lead developer of 2 moderately successful browser games quite a few years back, and plan on working on a new game soon. At the time, I wrote them in pure PHP (no template engine or anything of the sort). I'd like to start working on a new game, but have been out of the web development world for a while. Reading around, I hear a lot of good about Rails, Django, Node.js, etc., with which I have no experience (although I know my way around Python, Javascript, and the others quite well). So my question is the following- if I were to go in my old ways and go with PHP again, would I be making things hard for myself? Would picking something more "trendy" have a real impact on my development? In addition, does anyone have any pointers relating to specifically developing browser games with these more modern tools?

• 12.10 live dvd no video input

  - by mark kirby

  Hi I have been trying install Ubuntu 12.10, but as soon as it gets past my bios and to the screen with the blinking line in the top left, I get a no video input message on my tv (like when you turn the tv on with nothing connected). I have used live dvd's of both betas, alphas and daily build all with exactly the same results. Has any one else had this ? Is there a fix ? Dose this mean I can never upgrade my Ubuntu again ? (12.04 works ive been using since beta) My pc ,while old, should run this fine CPU = 2x Intel P4 HT @ 3ghz GPU = Nvidia Geforce 310 via HDMI RAM = 2 Gb DDR 2 HDD = 2 x 7200 rpm SATA Please help me I use Ubuntu exclusively on my pc and would like to keep doings so.

• Clean SOAP Calls from iOS - SudzC

  - by Richard Jones

  This is worth another mention. If you need to call SOAP web-services from iOS or Javascript, and lets face who doesn't. http://SudzC.com really delivers. You give it the URL to you're WSDL file (or upload a file) and it just spits out a ready to go Xcode project. I would point out that to get it to work 100% I changed line 204, in Soap.m (commented out line is old version, mine is below) //if([child respondsToSelector:@selector(name)] && [[child name] isEqual: name]) { if([child respondsToSelector:@selector(name)] && [[child name] hasSuffix: name]) { I consumed a Microsoft Dynamics NAV set of web-service pages no problem (and they tend to be fairly complex WSDL definitions).

• How to run Java application in KDE with Qt-like UI?

  - by squallbayu

  Continuing my question in Install Ubuntu or Kubuntu? I have tried Kubuntu (KDE), and it was very cool as cool as Ubuntu (GNOME). but there is little problem with its user interface when we start Java application (LimeWire, Netbeans, Eclipse). User interface changed to Metal, (which I think is a bit old school). Can we run it with Qt like UI?, such as when we start Java application in Gnome (run with GTK like UI/emulation GTK like UI)? I hear there is a class for Java in order to make Java application UI like Qt, called the Qt/Jambi bindings for Java. How can we integrate it in KDE when we start Java application? My other question is if not wrong, OpenOffice was built in Java,so why OpenOffice can run with Qt like UI in KDE?

• Handling player/background movements in 2D games

  - by lukeluke

  Suppose you have your animated character controlled by the player and a 2D world (like the old 2D side-scrolling games). When the user press right on the keyboard, the background is moved to the right. If the path is always horizontal, this is simple to do (incrementation/decrementation of the x-coordinate). But suppose that the path is instead a polygonal chain. My questions are: How do you move the background? How do you move the background if the game objects are managed with a physics engine like box2D?

• How can I connect my HP Photosmart C3100 printer in 10.04 (regression from 9.x)

  - by Brian

  My printer was working under 9.x. It is a an HP Photosmart C3100 series. When I open Admin-Printing no local printers are found. I try to add via Other (My local choices are Serial and other). I have tried many url's - ipp://localhost:631/ipp, http://localhost/ipp, localhost, 127.0.0.1, etc... None have worked. Under the networked I have tried JetDirect, using localhost and 127.0.0.1 and port 631. I have tried many options under IPP with different variants in the host trying to verify a printer. No luck .I tried LPD/LPR with localhost and tried the probe. no luck. I tried the cups admin via localhost:631 and that didn't work. On the old version its simply found the local printer, I might have picked the driver, I can't remember but it was the photosmart c3100 series that was working.I just can't get 10.04 to print.

• Techniques for Working Without a Debugger [closed]

  - by ashes999

  Possible Duplicate: How to effectively do manual debugging? Programming in a debugger is ideal. When I say a debugger, I mean something that will allow you to: Pause execution in the middle of some code (like a VM) Inspect variable values Optionally set variable values and call methods Unfortunately, we're not always blessed to work in environments that have debuggers. This can be for reasons such as: Debugger is too too too slow (Flash circa Flash 8) Interpreted language (Ruby, PHP) Scripting language (eg. inside RPG Maker XP) My question is, what is an effective way to debug without a debugger? The old method of "interleave code with print statements" is time-consuming and not sufficient.

• How can I make my game more popular without paying money?

  - by Marlon Drescher

  I am a game designer, software developer, composer and graphic artist and made the 3D Hack 'n Slay MMO Forgotten Elements on my own. It's playable at open Beta and will be released at the end of the year. I used Plain Old JAVA, JPCT 3D Engine, Tomcat Webserver and Blender 3D / Gimp to manage all the tasks. I developed the whole game from scratch. For me the hardest task in this challenge is probably the whole thing about marketing and advertisement. Because it is a independent project and I am the only person working on it, there is no money I could invest for making advertisement. But anyhow... How could it be possible to make this game more popular? What would you suggest me?

• Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

  - by DaimyoKirby

  This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

• Consultant in a firm that doesn't understand the tech!

  - by techsjs2012

  I got the job as a Consultant in a firm that has 3 other programmers. My job is to rewrite all the old system in Java, Spring etc but the staff programmers only know perl and the manager does not know any programming. I am trying to get them to understand that I have 6 projects to rewrite here but no one has design docs or spec. the staff programmers never had to write any documents. Plus I cant get the manager to understand the new java tech stuff.. he keeps asking some of the staff for views on things but the staff don't know it or understand it. Where do I go from here to make the manager understand that the staff programmers or someone has to write a design document so I know what to build. or if I have to write the documents how do I get the information?

• Gnome 3 freezes when switching workspaces

  - by Bill Cheatham

  I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?
