• How to install a Lexmark z600 series printer?

  - by Uri Herrera

  It has been a headache trying to install this printer. All the tutorials I found are for older versions of Ubuntu, and none of them work. How can I install this printer? Edit: HOWTO: Install PITA Lexmark Z600 Z615 and Dell Photo Printer 720 Setup Lexmark Z600 and X series printer on Ubuntu (i tried this one, only that it was translated to spanish, but it was the same instructions) HOWTO: Lexmark Printers I always get an error when extracting the converted tars with all of the tuts, invalid argument or the file doesn't exist. Looks like, i was missing some ia32 libs .. and that caused the errors with the tar files, anyways i still can't print now i get this, cups-insecure-filter How to install Lezmark Z600 series printer Here, the OP offers 2 debs, i installed them on a 32 bit Ubuntu install, now the printer gets recognized but still can't print, 'cause i'm missing a filter, "rastertoz600".

• Can't get Optimus to work with Ironhide on an Asus N53SN

  - by Musaab

  I installed Ubuntu 11.10 (Same issue in 11.04 btw) and then I installed Ironhide. I went through the configuration, chose the one with the highest confirmation for my system and tested it: > Error: Module nvidia does not exist in /proc/modules > P50 Disabling nVidia Card Succeded (the spelling error is theirs) And it changes nothing. I tried other configurations and got worse results. This has really become a major headache. Any solutions?

• XAMPP: Deamon is already running, but it's NOT apache

  - by TedvG

  This one is giving me a headache... I have installed XAMPP for Linux 1.7.7 on Ubuntu 12.10. I haven't installed the latest version because of the new security "feature" which makes XAMPP so secure I can't get it running... But that's another story. After it installed and ran ok for a couple of months, I now get the famous "XAMPP: Another web server daemon is already running." error while starting XAMPP. Now I've googled extensively and can rule out the following: There is no other Apache installation, just XAMPP There are no apache or apache 2 services running There are no services running that use port 80 (checked with netstat -an grep -w 80) I have also done a fresh install of xampp 1.7.7, but that gives me the same result. I think I have tried every solution on the first two result-pages of google and am nowhere nearer to a solution. Can anyone give me pointers on how to find the mysterious "Webdeamon" that is already running?

• Projectiles in tile mapped turn-based tactics game?

  - by Petteri Hietavirta

  I am planning to make a Laser Squad clone and I think I have most of the aspects covered. But the major headache is the projectiles shot/thrown. The easy way would be to figure out the probability of hit and just mark miss/hit. But I want to be able to have the projectile to hit something eventually (collateral damage!). Currently everything is flat 2D tile map and there would be full (wall, door) and half height (desk, chair, window) obstacles. My idea is to draw an imaginary line from the shooter to the target and add some horizontal&vertical error based on the player skills. Then I would trace the modified path until it hits something. This is basically what the original Laser Squad seems to do. Can you recommend any algorithms or other approaches for this?

• How do I install my Wacom Intuos 2 serial tablet?

  - by Gizmoatwork

  I've seen many topics on the subjects but they are too complicated for me. I'm not confident in compiling stuff. Is there some headache-free way to make it work under Ubuntu? Where do I start?

• Is there an alternative to k3dsurf in 12.10?

  - by Sean Fitzpatrick

  I've just upgraded to Quantal Quetzal on my home computer and discovered that the program K3dSurf has been removed from the repositories. (Presumably since it doesn't seem to be in active development and still depends on qt3 libraries.) Does anyone know of a similar program (user-friendly and versatile) for drawing 3D surfaces? This has been a mission-critical program for me when teaching multivariable calculus, so I won't be able to upgrade at work unless I can find a replacement. (Yes, I could install directly from the program's website, but dealing with obsolete libraries sounds like a giant headache.)

• MAMP Pro Installed On Mavericks 10.9

  - by cnps

  I have MAMP Pro Installed. I'm well aware with the advanced features of MAMP Pro I can change to different types of Hosts, but I wanted to know why my previous method would not work within mavericks. This was my usual working method in 10.8, but now with 10.9 it's a headache. The previous method would: Write a custom address with the host address: "#Virtual Hosts" 127.0.0.1 nameofsite.local go to /Applications/MAMP/conf/apache and open the httpd.conf file, scroll to the bottom and then add NameVirtualHost * DocumentRoot "/Applications/MAMP/htdocs" ServerName localhost DocumentRoot "/Users/Klimt/Sites/siteoffolder" ServerName clientA.local make sure the ports is set to 80, 443, 3306. reset MAMP PRO and then usually type in the url address and it's gold from there. any help?

• how to contribute the same source code to two separate open-source projects?

  - by Jason S

  Let's say there are two similar open source projects A and B, both licensed under the Apache Software License 2.0. I would like to contribute an improvement to both projects (because I don't know which one is administered better, and I would like to see my improvement show up in both). Is there a way I can contribute this improvement to both projects in a simple way? (One obvious approach is to start an open source project C licensed under Apache 2.0, but that's a headache for various reasons; I don't want to maintain a project myself)

• redefine shortcuts for keys being set to default after reboot

  - by MYA

  i am using PHPStorm editor on Ubuntu 14.04. Everything is so smooth that I am loving the experience (especially the workspace experience is amazing) however this bug is giving me headache... some of the editor's short-cuts clash with default Ubuntu keys (Alt + Ctrl + Left,Right,Up or Down arrow keys). I have changed the default keys to (super + Left,Right,Up and Down arrow keys) so they don't collide with my editor but after the reboot, Ubuntu changes are somehow reverting to default. This keeps comming again and again. i am sure there is a way out so therefore need help with that...

• What video graphic card would permit ubuntu's standard driver to work well?

  - by Rick

  I installed ubuntu 12.04. All seemed well until I installed the nvidia driver. Then crashola! This situation is untenable. It seems I cannot trust nvidia, and it seems that I cannot rely on ubuntu gurus to test 3rd party drivers. So, apparently some video card manufacturers do not care enough about the linux market to test their drivers, or are there too many 3rd party video cards so that ubuntu folks do not test any 3rd party video drivers? Hence the question: What video graphic card would permit me to use ubuntu's standard driver so that I do not have to rely on nvidia's or any other 3rd-party driver? Perhaps I could then install THAT card and have things work? The ubuntu standard driver actually worked prior to installing the nvidia driver, but not well, and that was because the display flickered, and flickering gives me a headache.

• Do you accept counter offers when recruiting experienced programmers? [migrated]

  - by MathAttack

  It is VERY hard to find good experienced programmers. Generally if they're performing well, their employers don't want to let them go, and many don't have resumes, let alone resumes in circulation. Let's say you find one who for personal circumstances is available. And let's say you make them an offer that's fair within your salary structure. And let's say you get a modest counter. (5-10% of the total offer side) Do you accept the counter? Part of me says, "Programmers like this are so rare, why let a small sum get in the way of hiring them?" The other part says, "This precedent will set up an annual headache." Thoughts? I know it's not black and white.

• Java vs COBOL programming examples

  - by Jodi

  I am a COBOL programmer, desperately trying to learn and program Java. Although I understand the OO priciples and concepts, I am at a lost putting all together. I am trying to find some examples on how code will look in COBOL vs Java - something a bit more complicated than "hello world" [I am past that initial headache! :-)], that includes OO principles - basically, a decent 1000+ liner in COBOL, with the Java code to work through. After working through book after book, doing the examples, and even writing small java programs at work, I think working through an example I can compare will be the best way to getting my thinking cap converted, and being able to do in Java what I can do after 10 years with COBOL. Can anybody help?

• Issues With IIS Hosting Two Domains From Same Folder [closed]

  - by Bob Mc

  I have two different domain names that resolve to the same ASP.Net site. Both domains are hosted on the same server, which runs Windows Server 2003 and IIS6. The sites are differentiated in IIS Manager using host headers. However, both of the sites point to the same folder on the local drive for the site's page files. I am occasionally experiencing an ASP.Net error that says "The state information is invalid for this page and might be corrupted." I'm the site developer so I've addressed all the relevant code-related causes for this issue. However, I was wondering whether having two domains/sites sharing the same folder for an ASP.Net application might be causing this intermittent error. Also, is this generally a bad practice? Should I make separate, duplicate folders for each of the domains? Seems like that can become a maintenance headache.

• How can I write data to a file that users can't easily edit?

  - by ThePlan

  While working on game saving and loading I figured I could just write all the variable values to a file and then load that file from it's default location anytime. However from the very beginning it sounded like an odd job. I know about serialization and boost, but that seems so complicated, I figured I'd keep it simple, but I've ran across this huge issue: No matter what file I can write with C++, the user can get their hands on it, they can edit their position, they can remove a boss, or add new weapons for themselves. My question here is: How can I create a file in C++ which cannot be editted or openned with a text editor such as Notepad (I'm not trying to make a file which is impossible to open, but a file which will give the user a headache if he tries to edit it through usual methods.)

• varchar(255) to varchar(MAX)

  - by JD

  Is it possible to change a column type in a MS SQL 2008 database from varchar(255) to varchar(MAX) without having to drop the table and recreate? SQL Server Management Studio throws me an error every time I try to do it using that - but to save myself a headache would be nice to know if I can change the type without having to DROP and CREATE.

  Hi, Has anyone had this error before when running reports in Crystal Reports 2008: Character set encoding from transport information [UTF-8] does not match with character set encoding in the received SOAP message [iso-8559]. I presume this indicates a file needs changing, but trying to fint it is causing me a real headache. There are references to UTF-8 all over the server. Any help would be great. Thanks, Lloyd.
