• Creating an install of Ubuntu to clone

  - by naaronne

  I work on a team with several other developers. We all have similar hardware and we all run at least the same base development software. We are wishing to upgrade from 10.04 to 10.10 doing a clean install. I am looking for a way to do a base install of Ubuntu, including all our common applications, then clone it to each of the developers drives and then let them further customize their own install. Some considerations would be giving the developer the ability to have their own person id and not the same as which the base install was done with. I know they do this on VMware installs and corporate installs of Windows that can then be customized, but I have not seen this done with Ubuntu yet. Thanks

• OpenGL Vertex Attributes - Normalisation

  - by Daniel

  Alas, I have searched, and have found no definitive answer. When would you normalize the vertex data in OpenGL using the following command: glVertexAttribPointer(index, size, type, normalize, stride, pointer); I.e when would normalize == GL_TRUE; what situations, and why would you choose to let the GPU do the calculations instead of preprocessing it? All examples I have ever seen, have this set to GL_FALSE; and I cannot personally see a use for it. But Khronos aren't stupid, so it must be there for something useful (and probably common).

• Not able to create screenshot of when menu is active [closed]

  - by gotqn

  Possible Duplicate: Screenshot of active window doesn’t work I am using Ubuntu 12.04 and I am searching for a program that will let me to do screenshot of my menus too.

This happens to with applications launchers menus in the left navigation panel. On windows I am using Gadwin Pro. Is there any alternative on Linux?

• Generating AdSense ad impression?

  - by Danny

  I owned two website. Let's say as example www.first.com and www.second.com. I have two apps in Google chrome-store whose app URL is: app1 URL = www.first.com/currency_converter.php app2 URL = www.first.com/currency_converter.php respectively. Currently if user lunch/click on first app URL then I am forwarding them to my first website homepage (www.first.com), where I have AdSense code with currency converter app. In this way I am generating Google ad impression and traffic for my first website (i.e www.first.com). So is this valid way? Does I am violating any Google AdSense rule? Please provide your reply or suggestions. P.S.: Please comment, if my question is not clear, I will try to write it in some other way.

• delete /var/cache/* How can I fix it?

  - by user110474

  I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back. I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically? If not, which directories do I have to create in /var/cache/ manually to let everything work fine? I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there. I hope somebody can guide me to fix this issue.

• SEO for images: can I use a different (cookieless) domain?

  - by Oliver

  Hello, We want to increase the value of some of our important images by means of SEO, and we want to start serving them from a different, i.e. cookieless, domain. We want to go from http://www.example.com/images/1234.jpg to http://www.example.com/germany/bavaria/landscape.jpg which can easily be done via URL rewriting. Then on the other hand, we would like to serve the image from a completely different domain, let's say http://www.examplestatic.com/germany/bavaria/landscape.jpg, to save the overhead of sending the cookie from www.example.com. Somehow I feel that this is not a good idea because I move the image away from the content by putting it on a different domain. Can anyone shed some light on this problem? Naturally, I would just use a different subdomain, e.g. img.example.com, but we already use subdomains for languages and our cookies are valid for all subdomains of example.com, so this won't help. I'd really appreciate any hints. Cheers,

• How to tell google a blog article has been updated?

  - by Scott

  The URL of my posts has the publication date and slugged title, but how can I best show google search users that an article has been updated since its original publication? I was considering devoting a few characters of the meta description (e.g. "updated 2013-Aug-1), or doing so under the first h1 tag. I don't want to hurt the seo value of my site, but I also want to let users know that articles have been substantially updated since their publication. Is there a better way to do this?

• How You Helped Shape Java EE 7...

  - by reza_rahman

  For many of us working with the JCP for years, the commitment to transparency and openness is very clear. For others, perhaps the most visible sign to date of this high regard for grassroots level input is a survey on Java EE 7 gathered a few months ago. The survey was designed to get open feedback on a number of critical issues central to the Java EE 7 umbrella specification including what APIs to include in the standard. The survey was highly successful with a large number of high quality responses. With Java EE 7 under our belt and the horizons for Java EE 8 emerging, this is a good time to thank everyone that took the survey once again for their thoughts and let you know what the impact of your voice actually was. I've posted the details on my personal blog. I hope you are encouraged by how your input to the survey helped shape Java EE 7 and continues to shape Java EE 8. Maybe now is the time for you to get more involved :-)?

• How do I create a LiveUSB that lets me install any Ubuntu version?

  - by Dariopnc

  What I'd like to do: have Ubuntu installed on a USB drive and from there install any ubuntu version on a hdd. This is kinda different from using usb-creator because I'd like to have a persistent ubuntu install on the USB drive and not upgrade it every 6 months. From there I'd like to be able to install the most recent ubuntu version. I think it's just a matter of configuring ubiquity, but don't know if this is the case and how exactly do this. EDIT: Let's clarify the persistent thing: suppose I have my USB with ubuntu precise on it suppose quantal is out in the wild suppose that I want to install quantal on the hdd of a computer suppose that I want/can use only the USB drive with precise on it I should erase/upgrade precise on the USB drive to quantal and then install it on the hard drive I don't want to touch my ubuntu install on the USB drive, I'd like to be able to install the newer ubuntu version (quantal) on a hdd from another one (precise) on a USB drive I'd better avoid upgrading the installation on the hdd Hope this helps

  I'm using ubuntu 12.04.1, last upgraded from 12.04 I'm using mts mblaze to access internet. Two days ago, I was using vpn on my system, suddenly cisco disconnected & my system hung while I was accessing my office system. I didnt' have any other idea, so I forcibly shut down the system. After that, connection is made, but firefox or chromium both don't find any page. I think there's some problem with the system package. Please let me know a good solution. Regards, Chetan

• How can I repair a corrupt kernel if no others are installed?

  - by Willi Ballenthin

  I've been running Ubuntu 10.04 on my laptop for quite some time. When I went to boot it up this morning, BAM! kernel panic (which immediately lead to human panic) when loading the kernel. So I've spent much of the day troubleshooting, and my current theory is that the FS is fine, but that the kernel image may be corrupt. Let's go with this current theory for the sake of this question, as I am interested how it is done. How can I replace the kernel image if I have no bootable kernels? Can I boot to a 10.04 live CD, copy the the vmlinuz-2.6.3x... to the HD and go from there? Wouldn't I want to copy the initramfs as well, but configured for the desktop system? Can I generate this from the live CD?

• How much to pay for artwork in an indie game?

  - by f20k

  I am an indie developer and I need some detailed artwork. How much is reasonable to pay an artist for say 20 character designs? I know it depends on the artist's skills, etc, but I am wondering what to expect so that I can budget it. Edit: Let's say cartoon-ish art (Example - not necessarily in that level of detail but that kind of cartoony-art style). No 3-d modelling - The art will be used as still images in game and for promotional reasons. I'd provide a base sprite design for them to expand on and detail. Also, some numbers would be nice - I like numbers. Even a range is helpful. Like: expect to spend $x2 ~ $x1 for top-notch and $y2 ~ $y1 for decent quality. I understand I can ask at some indie-help site but, if an artist says something like $1000 for 20 designs, I wouldn't have any idea if it's reasonable / good deal / bad idea etc.

• How to run a file with sudo without a password?

  - by John

  I've made a script that preforms various system tasks, that I run regularly, but I have to use sudo to run the script, despite the fact that I own it because it runs root privileged commands. How can I add make sudo let me run this one file without having to enter my password every time I run it? I know that there are questions regarding running commands without a password, but I wasn't able to find one on running a file without a password. I am aware of the security risks, but I'm at home on a computer that I trust.

• How to implement Fog Of War with an shader?

  - by Cambrano

  Okay, I'm creating a RTS game and want to implement an AgeOfEmpires-like Fog Of War(FOW). That means a tile(or pixel) can be: 0% transparent (unexplored) 50% transparent black (explored but not in viewrange) 100% transparent(explored and in viewrange) RTS means I'll have many explorers (NPCs, buildings, ...). Okay, so I have an 2d array of bytes byte[,] explored. The byte value correlates the transparency. The question is, how do I pass this array to my shader? Well I think it is not possible to pass an entire array. So: what technique shall I use to let my shader know if a pixel/tile is visible or not?

• Should I use parentheses in logical statements even where not necessary?

  - by Jeff Bridgman

  Let's say I have a boolean condition a AND b OR c AND d and I'm using a language where AND has a higher order of operation precedent than OR. I could write this line of code: If (a AND b) OR (c AND d) Then ... But really, that's equivalent to: If a AND b OR c AND d Then ... Are there any arguments in for or against including the extraneous parentheses? Does practical experience suggest that it is worth including them for readability? Or is it a sign that a developer needs to really sit down and become confident in the basics of their language?

• How to Get Vine App for Windows Phone in Canada

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/11/12/154613.aspxI wanted to download the Vine app for Windows Phone, but I couldn’t find it in the app store when I browsed it on my Nokia. I went to the app’s page on the app store where I saw this: One of my Twitter peeps from Winnipeg, Len, commented that he was able to install it from the website. So I went back and noticed that there’s a “Download and Install Manually” link towards the bottom of the page, which will let you download the .XAP file directly. So I emailed myself the link, opened it on my phone, and voila – Vine is now installed! What’s the point of limiting apps by region if we can just manually download and install the file anyway? Weird. D

• Expiring timed actions a good idea?

  - by Bart van Heukelom

  We have an online game where players sometimes have to wait a while (say 30 minutes) before a process they intiated completes. This encourages them to come back later. An example of this is growing crops in Farmville or basically any action in the Sims Play4Free. Now, however, there is the idea to let these processes expire, so if the player doesn't 'reap' them in time (e.g. within 4 hours) they are aborted. I'm a bit sceptical about this. How will this make players come back more often? Is not the reward of reaping the process enough for that? Can we expect players to fit their daily schedule around our game, maybe even set the alarm clock at night? Won't this just cause players to give up on starting these processes in the first place? I realise this may be too subjective for this site, so I'll end with a concrete question: Do (m)any other online free-to-play games employ this technique?

• Menus and text boxes look graphically corrupted in 12.10

  - by Stanton.Sculpture

  If I let my computer run long enough the screen gets glitchy or graphically corrupted only in certain areas i.e. in text related boxes, menus, menu bars, scroll bars, the system monitor window, etc. It becomes difficult to read what I am typing. Its been happening quite often and I can only fix it by restarting the computer, but its only a matter of time before it happens again. Don't know what else to do, its been a thorn in my side for quite some time now and I need a fix soon because its only gets more frequent until I'm rebooting my computer five times a day. I attached a picture of what happens to this bug report: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1083474 I know I can repeat this bug but I don't know how to catch it and document it. Any help would be greatly appreciated. Thank you

• Is it bad practice to call a controller action from a view that was rendered by another controller?

  - by marco-fiset

  Let's say I have an OrderController which handles orders. The user adds products to it through the view, and then the final price gets calculated through an AJAX call to a controller action. The price calculation logic is implemented in a seperate class and used in a controller action. What happens is that I have many views from different controllers that need to use that particular action. I'd like to have some kind of a PriceController that I could call an action on. But then the view would have to know about that PriceController and call an action on it. Is it bad practice for a view to call an action on a different controller from which it was rendered?

• Automatically move Xubuntu panel to external monitor

  - by user1291235

  I am using xubuntu 13.04 with a dualmonitor setup. (external monitor as primary, laptop als secondary) I am using xandr to makeup my monitorsetup. However I recognized that the xubuntu panel on the top by default will always be placed on the laptop monitor. I know that i can move the panel via the panel preferences. This works. But i want to somehow either let it move automatically to the right monitor (the primary one) or to move it with a terminal command (so i can create a script which takes care of moving the panel to the primary monitor)... any ideas?
