• What is a good method for coloring textures based on a palette in XNA?

  - by Bob

  I've been trying to work on a game with the look of an 8-bit game using XNA, specifically using the NES as a guide. The NES has a very specific palette and each sprite can use up to 4 colors from that palette. How could I emulate this? The current way I accomplish this is I have a texture with defined values which act as indexes to an array of colors I pass to the GPU. I imagine there must be a better way than this, but maybe this is the best way? I don't want to simply make sure I draw every sprite with the right colors because I want to be able to dynamically alter the palette. I'd also prefer not to alter the texture directly using the CPU.

• Kile missing "Settings" dialog after update to kubuntu 12.10

  - by William

  After update to Kubuntu 12.10, I can no longer access configuration options in Kile from Settings-Configure kile (or whatever the menu entry was for configuration). In fact, "Settings" menu has only five entries: "Define current document as master document", "System check", "Show side bar", "Show message bar", and "Toolbars shown." I did a fresh install of Kubuntu 12.10 on one of my other computers, and same problem. I even tried adding the (unsupported) ppa:kile/stable, but the problem persists. Any ideas? I need to access settings to set PDF Latex to use "modern" compilation mode, so that I can use synctex.

• Client side prediction/simulation Question

  - by Legendre

  I found a related question but it doesn't have what I needed. Client A sends input to move at T0. Server receives input at T1. All clients receive the change at T2. Question: With client-side prediction, client A would start moving at T0, client-side. All other clients receive the change at T2, so to them, client A only started moving at T2. If I understand correctly, client B will always see client A's past position and not his current position? How do I sync both client B and client A?

• How long to wait before Humble Bundle games appear in Software Centre?

  - by Synesso

  At software-center.ubuntu.com it says Thank you for downloading your Humble Bundle games from the Ubuntu Software Center Notes: As these games have been recently added to Ubuntu Software Center it might take a minute for them to appear. If you see a "Not found" message, Ubuntu Software Center is working in the background to update the list of available apps. When I click on a link, the software centre opens and it says There isn’t a software package called “swordandsworcery” in your current software sources. I have waited for about 30 minutes now. I have also executed sudo apt-get update & restarted software centre to no avail. Do I keep waiting?

• Recommend hosting with fast MySQL database please [closed]

  - by Keith Groben

  Possible Duplicate: How to find web hosting that meets my requirements? I am frustrated to no end with my current hosting provider, mediaTemple. Yes, they are flashy, and have some decent degree of flexibility with their GS plan, which I have. But anytime I install a site that needs a database, it is slow. like really slow. Taking anywhere from 10 - 15 seconds just to load a page. I would host in house, but there are a lot of complications that come with a LAMP server that I don't want to deal with. Honestly, I'd rather spend the time developing. What can you recommend?

• 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)

• memory and time intensive php task

  - by Goddard

  Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

• How Can I Upgrade to 11.10 from the Command Line?

  - by nmagerko

  I am trying to upgrade my 11.04 Ubuntu operating system to 11.10, as the current system is not the most recent. However, I cannot use the GUI to upgrade - as from past experience I have learned this - because my graphics hardware only works on 10.04 to 11.04 (non-inclusive) and from 11.10+. So once I can get to 11.10, I should be just fine. Because of this, I need to find a way to upgrade the OS from the command line. Can this be done? Thanks for any and all help.

• Migrate from Thunderbird to Mutt

  - by deshmukh

  I am contemplating moving from Thunderbird to Mutt (provided it is feasible) to move to a faster, simpler application. My current Thunderbird set-up consists of multiple IMAP accounts (gmail and google apps). Only selected folders (read labels) in each IMAP account are stored locally. For all other folders, I glance through the headers and open a message only if I find it interesting. I also use folder bookmarks to navigate to folders quickly. I also move messages across folders with keyboard shortcuts. Is it possible to replicate the set-up in Mutt? Can someone share/ point to a sample muttrc file that does the same thing? It would be great if the muttrc file is adequately commented. On a side note, will it also be possible to import my messages from Thunderbird locally? That will save me considerable network traffic (about 2GB data stored locally).

• Wide gap in my resume as a Java developer. What are must-have skills required to get hired those days? [closed]

  - by OnlineAlien

  For some legal reasons I haven't worked for anybody for the last 12 years. I am a java web developer or at least I am thinking so. For this period I have been working on my project- some sort of business network - and I did few small jobs, so right now I feel I am far behind in terms of my skills and the skills needed today. I lingered too long on Struts and Hibernate and thought that could the job for my project. I need to get a job, right now, so I am spending most of my time brushing my skills. My question is: What are the current necessary skills that could convince employers to hire me regardless of my past employment or the lack of it. Right now I am on AspectJ, IoC and Spring Thanks

• Manually updating HTML5 local storage?

  - by hustlerinc

  I'm just starting out HTML5 game developement (and game dev in general) and watching all the videos and tutorials available something has crossed my mind. Everyone keep saying I should set the cookie's (or cached files) to be expired after a certain amount of time. So that when it reaches that time the browser automatically downloads all assets again, even if it's the same asset's. Wouldn't it be possible to manually define the version of the game? For example the user has downloaded all the files for 1.01 of the game, when updating I change a simple variable to 1.02. When the user logs in it would compare his version to the current and if they are not equal only then it downloads the files? This could even be improved to download only specific files depending on what needs to be updated? Would this be possible or am I just dreaming? What are the possible downsides of this approach?

• Tunnels in pseudo 3D racing game

  - by Nicholas

  How would one go about doing tunnels in a pseudo 3D racing game ? The main problem I have at the moment is perspective - I cant think of a way, beyond having to Z sort the sprites and tunnel coordinates, so that vehicles are displayed in front of the tunnel entrance and somehow block the display when out of site. I would like my tunnels to be used on both flat, curved and hills and slopes. The tunnel enterance/exit is made up of 3 separate graphics, (left, right and top), whilst inside the tunnel it is just one line graphic along the top (the idea being its supposed to be a set distance above the current vertical road position). As you can see from the picture, the vehicles are still being rendered whilst in the tunnel. I've converted the Code Incomplete road system to GLBasic.

• Workspeace view shows first workspaces out of border at left

  - by Jeremi Roivas

  I am using nvidia-current and edited from settings my monitors so that my second monitor is at left and unity-panel shows only in my main monitor. How ever now the workspaces images have shifted so that second monitor first workpsaces are moved out of the left border and when the monitor is not turn on I can't see the the workspaces there. Sometimes programs have been moved when monitor is been flashed to the workspace shown in out of border and I have no means to move the program windows into my main workspace views. Image: http://but.fi/2em As you see the second monitor works as it should work but my main monitor is fooked. Is this possible way to fix this some how?

• Nvidia Driver versions?

  - by Patrick Krenz

  I've looked all over and can't find any reason as to why or how Nvidia names their drivers. for example they have a 330.xxx/340.xxx series that are current but also a 300.xxx and i've found that they aren't always release in order by number. Here's an example on there site with version and release date 331.38 - January 13 334.16 - Feb 7 331.49 - Feb 18 I'm really confused about what driver to actually go with, a few different series versions seem to work adequately and I just want to have an understanding of it and what the best option to work from would be. I really appreciate any information

• What percent of visitors should click on the next page before you enable prefetching?

  - by Kevin Burke

  Mozilla Firefox and Google Chrome support prefetching via an HTML tag: <!-- in chrome --> <link rel="prerender" href="http://example.org/index.html"> I suppose it is always worthwhile to include this tag if 100% of users on a page click on the "Next Page" button or similar, and never worthwhile to include it if only 2% or 3% of users visit the following page. At what percent of clicks should you turn on prefetching of the next page? 65%? Also, does the calculus change if the current page is HTTP and the next page is HTTPS?

• We Heart Discussion Forums (and Know You Do Too)

  - by oracletechnet

  It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

• Beginner: How to Make Explorer Always Show the Full Path in Windows 8

On the right-hand side click on options and then select Change folder and search options from the drop-down. When the Folder Options dialog opens, switch over to the View options.

• How to get rid of the orange highlight in Unity?

  - by user74660

  I've installed Ubuntu 12.04 LTS and I'm using Unity. I also installed Adwaita theme and Elementary icons. Everything is cool. Highlightings are blue, as I want them to be, but there are some places where the default orange color remains: When clicking on Workspace Switcher, the borders of the current or the selected workspace are still orange. When dragging a window to the edges of the screen, the highlight effect for the Snap Window feature is still orange as well. All other highlights are blue, according to the Adwaita theme. So, how can I get rid of those two mentioned orange highlights and turn them into blue, following the Adwaita color theme? Thanks for your attention. brunces

• ETL Software Research Question

  - by WernerCD

  Where I work, we use an in-house ETL solution that's homegrown and has been around for 5-10 years. I'm still new to my data analysis job, but I was wondering about the ETL tools that are out there. This is a new area for me. My situation, and job, is basically digging in a set of databases (DB2, SQL2005, Citrix, Ancient Cobol Database with a SQL Wrapper on top, MySQL, etc). Gather the desired information. combine the different datasets into one set. output into a file of choice (CSV, Tab Separated, Pipe Separated, XLS, etc). FTP to customer. I guess what my real question is, given my job, what are some good ETL suites that I can look at and compare to my in-house tools? This is more to research some other options. Ultimately, I'd either suggest a new solution or get options/ideas to improve our current app.

• Layout of experienced programmer Resume? [closed]

  - by mob1lejunkie

  What layout of resume works best for experienced programmers? Currently my layout is: Contact Details Focus (goal) Technical Skills Professional Experience (Responsibilities + achievements at each job) Education Interests I feel my current layout uses up too much valuable space. Most of the online templates feel like junior Resumes with emphasis on education so I am not sure how I can improve it. I wonder how many hiring managers actually care about goal/objective? To me it looks useless. Also, is it necessary to have summary of technical skills/technologies? If so, would it not make more sense for it to be mentioned later in the Resume rather then at the top? Finally, do you have separate section for achievements? Many thanks.

• How to programmatically construct textual query

  - by stibi

  Here is a query language, more specifically, it's JQL, you can use it in Jira, to search for issues, it's something like SQL, but quite simpler. My case is that, I need to construct such queries programmatically, in my application. Something like: JQLMachine jqlMachine = new JQLMachine() jqlMachine.setStatuses("Open", "In Progress") jqlMachine.setReporter("foouser", "baruser") jqlMachine.setDateRange(...) jqlMachine.getQuery() --> String with corresponding JQL query is returned You get my point I hope. I can imagine the code for this, but it's not nice, using my current knowledge how I'd do that. That's why I'm asking. What you'd advice to use to create such thing. I believe some patterns for creating something like this already exist and there is already best practices, how to do that in good way.
