  • Game-a-Week One Completed

    - by Matt Christian
    Last night I finished my Game-a-Week One and felt and extreme sense of accomplishment with what I finished in a single week. I removed all traces of the JigLibX code since it wasn't working properly due to my implementation and got my collision working thanks to some BoundingSpheres and Riemer's tutorials.  However, since the characters are Corndogs a rectangle bounding box would have made more sense although the bullets are only able to move forward currently. While developing it in a week was a challenge, developing it in a week while maintaining proper coding standards and clean, reusable code was damn near impossible.  It's possible my next step will be to either refactor it or move onto Game-a-Week Two. I will post a link to the game ZIP in the future.

  • Crashing/freezing problems with an Aspire One 722

    - by tim
    After several annoying points with installing ubuntu 11.10 on my acer aspire one 722 i finally made this run. After installing i had freeze issues and solved them by putting network boot on first priority on the bios. Yesterday all worked fine, no problems with wlan etc. But today all is crashing down. Atm iam at the university and tried to log into the public wlan. With that came : i cannot shut down, terminal is not working, very slow perfomance, some apps are starting like libre office, some not like system manager, buttons are not reacting, wlan symbol is spinning all the time. Any suggestions i can do?

  • How does one handle an incorrect resource file?

    - by AedonEtLIRA
    I'm starting the parser that will handle one of the key features of my app and realizing exactly who easy it would be for me to screw up a resource file that is provided to the application. For example, a simple resource that I provide to my app is a JSON file that contains an entity layout (name, fascia, location etc...). It would be easy for me to leave out the name of the entity or misspell the JSON key. Obviously catastrophic failures during parsing are to be handled in a try/catch, but how would subtle failures (such as a dyslexic spelling of name) be handled?

  • Research about best way to present multiple products on one page

    - by Michael Dibbets
    I am updating a webshop page. This is a fairly simple page that displays all the products that we currently sell. The page in development is visible here ( https://www.ortho.nl/wwebshop ). Now I was curious, and since I can't find anything via google etc..(probaly don't know the right keywords) what the best way is to present multiple products on one page. Should you use borders? Should you use colours? Which colours? what kind of tweaks will direct the customers attention to the right place? Does anyone know from experience or via research(and could you point me in the right direction to find that research) what the best way to present products is so conversion/clickthrough is optimised?

    - by velocityxyz
    I was wondering if there is a was a way to read rgb values from an image into a one dimensional array in C#. If it doesnt make sense, in java I would do something like this. int[] pixels; BufferedImage image = getClass().getResourceAsStream("asdfghjkl.png"); int w = image.getWidth(); int h = image.getHeight(); pixels = new int[w * h]; image.getRGB(0, 0, w, h, pixels, 0, w) ; So any help would be great, or if you can point me in the right direction, that'd be great

    I have been searching for an Ubuntu video I saw 1-2 months ago where they guy was demonstrating Ubuntu One and how he used it to sync local profile stuff across different machines.

Not sure if we are allowed to ask these questions but here goes.

  • Cannot mount one usb disc, although other mounts automatically after 12.10 upgrade

    - by Allen Williams
    Since upgrading to 12.10, switching on or attempting to mount one of my usb hard drives gives this error message: Error mounting system-managed device /dev/sdg1: Command-line `mount "/mnt/usb-ST350041_8AS_60CAFFFFFFFF-0:0-part1"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdg1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg | tail gives (inter alia): [ 1080.727830] sdg: sdg1 [ 1080.732003] sd 8:0:0:0: [sdg] Attached SCSI disk [ 1081.383633] FAT-fs (sdg1): Unrecognized mount option "x-gvfs-show" or missing value [ 1871.160973] sdg: sdg1 The drive cannot be mounted, but is recognized by the system as a "place". I am not a technical bod; I cannot take this further myself and any help would be much appreciated.

  • Why would one overload the && and & operator?

    - by acidzombie24
    The same question goes for | and ||. Why would one overload or 'use' the & and && operator? The only use i thought of are Bitwise Ands for int base types (but not float/decimals) using & logical short circuit for bools/functions that return bool. Using the && operator usually. I cant think of any classes that use those operators. Absolutely none. I know a class might support + (and not '-') which combine two strings together. I seen an object such as datetime overload '-' so two dates can be subtracted to make a timespan (obviously you cant add two dates) but i never seen &, &&, | and || used. Does anyone know of a use? In any language?

  • Acer Aspire One 722 broadcom 4313 wifi

    - by Colin Matheson
    I had an Acer Aspire One 722 with the Atheros Wifi card and it worked fine on 11.04. So we bought 200 of them for our school. However these all came with the Broadcom BCM4313 wireless card and there are issues. It is using the brcmsmac driver and they connect initially. However after a time (sometimes just a few webpages) some of them lose connection. However, they still have an IP and network-manager says they are connected, but no pages load and you can't ping anything on the LAN or internet. A disconnect/reconnect can fix it, but sometimes a restart is required. It happens frequently so is a major issue. Lots of broadcom drivers are blacklisted: bcm43xx, b43, brcm80211. Any ideas or experiences with the broadcom4313 card? Please save these computers from a Windows fate!

  • An application asks to unlock the keyring on startup, but it doesn't say which one

    - by Idan K
    A couple of weeks ago a popup has appeared whenever I startup telling me that an application wants to access the keyring but it doesn't say which one. I'm used to seeing the application name on the popup but here it just says 'application'. I haven't changed any passwords or did anything that might have something to do with that, to my knowledge. I saw this question but like I said, I haven't changed any of my passwords, and I don't want my keyring password to be empty. How can I find out which application is asking to unlock to keyring and fix it?

  • Apache 301 redirection from one domain to another

    - by Sebastien Lachance
    I'm trying to set a redirection in my VirtualHost configuration for my website. So far I am able to redirect non www trafficto the www address like this : <VirtualHost: *:80> ServerAlias www.gcbeauce.com RewriteEngine on RewriteCond %{HTTP_HOST} ^guidedescommercesdebeauce\.com$ [NC] RewriteRule ^(.*)$ http://www.guidedescommercesdebeauce.com$1 [R=301,L] But what I also want is to redirect the old domain to this new one. I have tried adding : RewriteEngine on RewriteCond %{HTTP_HOST} ^guidedescommercesdebeauce\.com$ [NC] RewriteCond %{HTTP_HOST} ^gcbeauce\.com$ [NC] RewriteRule ^(.*)$ http://www.guidedescommercesdebeauce.com$1 [R=301,L] But nothing happens. Am I missing something here?

  • SharePoint Client Object Model: Step One

    - by PeterBrunone
    I almost didn't make it out alive.  I followed the instructions in every piece of sample code and every forum post by someone who had no idea why their client OM code wasn't working, and my code still wouldn't get past the page load.  I kept getting "'Type' is undefined" errors when sp.core.js tried to register the SP namespace.As it turns out, you need the help of the default master page (or one like it) to get the object model loaded.  Once I told my sample page to use the default master and modified everything accordingly, it hooked up and ran just fine.Now I can finally get some work done.

  • Moving from one DNS provider to another

    - by Senthil Kumaran
    I had registered with a particular DNS provider X and I have been unhappy with their services and now when the time for renewal came, I did not renew and I let it expire. I am hoping that once it is expired from this provider, I would be able to sign up for the same domain name from an alternative provider which I have tested and I am satisfied. What kind of precautions should I take? The domain name is not a critical one, it is of a NGO and we prefer to own it again without any change in the name. The information given by the expiry notice says Domains can be renewed between 90 days before and 14 days after the expiry date. If domains are not renewed they will be removed from the account and set for deletion. Should I wait for time till gets deleted at their end so that I can sign up for the same from another provider?

  • How does one block unsupported web browsers?

    - by Sn3akyP3t3
    Web browsers with an end of life no longer receive security updates which not only makes them vulnerable to the end user, but I imagine its not safe for the server's which receive visits by them either. Is it practical to block or enforce and notify the end user that their browser is unsafe and unsupported? If so, how would one achieve that? I don't know of any official or crowd-sourced listing with that information to parse and keep up to date. I'm aware that the practice can be custom built with User Agent parsing and feature detection for HTML5 enabled browsers.

  • Ethernet on an Acer Aspire One D255E not working

    - by Dustin
    Ok very frustrated here, but hopefully can find an answer here. I have an Acer Aspire One netbook D255E. I installed 10.04 desktop edition via live USB, only to find out ethernet is not connecting. The thing is, I had installed previously 10.04 thru wubi as 30GB, but wanted more so did this install. With the Wubi install it worked great internet worked added LibO, mint menu ect. So I know it could work, and it works on Win 7(what little GB is left). I have ethernet enabled, and gave myself all permissions, but still not working. Thank you for any help, and if you do more details in the steps i need to take the better :).

  • How To Smoothly Animate From One Camera Position To Another

    - by www.Sillitoy.com
    The Question is basically self explanatory. I have a scene with many cameras and I'd like to smoothly switch from one to another. I am not looking for a cross fade effect but more to a camera moving and rotating the view in order to reach the next camera point of view and so on. To this end I have tried the following code: firstCamera.transform.position.x = Mathf.Lerp(firstCamera.transform.position.x, nextCamer.transform.position.x,Time.deltaTime*smooth); firstCamera.transform.position.y = Mathf.Lerp(firstCamera.transform.position.y, nextCamera.transform.position.y,Time.deltaTime*smooth); firstCamera.transform.position.z = Mathf.Lerp(firstCamera.transform.position.z, nextCamera.transform.position.z,Time.deltaTime*smooth); firstCamera.transform.rotation.x = Mathf.Lerp(firstCamera.transform.rotation.x, nextCamera.transform.rotation.x,Time.deltaTime*smooth); firstCamera.transform.rotation.z = Mathf.Lerp(firstCamera.transform.rotation.z, nextCamera.transform.rotation.z,Time.deltaTime*smooth); firstCamera.transform.rotation.y = Mathf.Lerp(firstCamera.transform.rotation.y, nextCamera.transform.rotation.y,Time.deltaTime*smooth); But the result is actually not that good.

  • Services - Separate Sites or One Site - Impact on SEO

    - by Lynda
    I have a client who is a lawyer that specializes in Criminal Defense and DUI, however, he does not show up well in Google. In researching the sites that rank better have much more content for those specialties than his site does and my thought it that he needs to add more quality content to rank better for those searches. On his site he mentions his specialties, but also he has various personal things on his sites that reflect his interest. These are clearly separated from the business portion. My questions are should he 1) separate his personal information into a new domain and 2) should he have a separate URL for each of his specialties? OR would one URL work as long as everything is clearly separated? I read once that for legal services to rank well you should make a separate site for each specialty and have that site focus solely on that service.

    - by Yaniza Familia
    This is my situation. I have about five different apps and they all perform well. I will like to make one app with all these little apps. How can I go about this with a master view application? Also these were created with nib file (xib) no storyboard. Can I create my files with storyboard or do I have to continue creating files with xib? Also, what to do with app delegate (UIApplicationDelegate) methods that are implemented in all applications? Please explain no knowledge on this part.

  • One-way platforms in UDK

    - by Jordaan Mylonas
    I'm looking to make a multi-player platforming game using UDK. I'm currently doing feasibility research, to make sure I will reasonably be able to do all of the technical things I want to do. The first major hurdle I've come across without being able to find as answer, are one-way platforms. That is to say, platforms through which a player can jump up, but not fall through (unless they choose to). These are commonly seen in games like Mario, Kirby and Smash Bros. Does anyone know how such a system would work within UDK? I can think of solutions that might work for single-player, but not multi.

  • Social Engagement: One Size Doesn't Fit Anyone

    - by Mike Stiles
    The key to achieving meaningful social engagement is to know who you’re talking to, know what they like, and consistently deliver that kind of material to them. Every magazine for women knows this. When you read the article titles promoted on their covers, there’s no mistaking for whom that magazine is intended. And yet, confusion still reigns at many brands as to exactly whom they want to talk to, what those people want to hear, and what kind of content they should be creating for them. In most instances, the root problem is brands want to be all things to all people. Their target audience…the world! Good luck with that. It’s 2012, the age of aggregation and custom content delivery. To cope with the modern day barrage of information, people have constructed technological filters so that content they regard as being “for them” is mostly what gets through. Even if your brand is for men and women, young and old, you may want to consider social properties that divide men from women, and young from old. Yes, a man might find something in a women’s magazine that interests him. But that doesn’t mean he’s going to subscribe to it, or buy even one issue. In fact he’ll probably never see the article he’d otherwise be interested in, because in his mind, “This isn’t for me.” It wasn’t packaged for him. News Flash: men and women are different. So it’s a tall order to craft your Facebook Page or Twitter handle to simultaneously exude the motivators for both. The Harris Interactive study “2012 Connecting and Communicating Online: State of Social Media” sheds light on the differing social behaviors and drivers. -65% of women (vs. 59% of men) stay glued to social because they don’t want to miss anything. -25% of women check social when they wake up, before they check email. Only 18% of men check social before e-mail. -95% of women surveyed belong to Facebook vs. 86% of men. -67% of women log in to Facebook once a day or more vs. 54% of men. -Conventional wisdom is Pinterest is mostly a woman-thing, right? That may be true for viewing, but not true for sharing. Men are actually more likely to share on Pinterest than women, 23% to 10%. -The sharing divide extends to YouTube. 68% of women use it mainly for consumption, as opposed to 52% of men. -Women are as likely to have a Twitter account as men, but they’re much less likely to check it often. 54% of women check it once a week compared to 2/3 of men. Obviously, there are some takeaways from this depending on your target. Women don’t want to miss out on anything, so serialized content might be a good idea, right? Promotional posts that lead to a big payoff could keep them hooked. Posts for women might be better served first thing in the morning. If sharing is your goal, maybe male-targeted content is more likely to get those desired shares. And maybe Twitter is a better place to aim your male-targeted content than Facebook. Some grocery stores started experimenting with male-only aisles. The results have been impressive. Why? Because while it’s true men were finding those same items in the store just fine before, now something has been created just for them. They have a place in the store where they belong. Each brand’s strategy and targets are going to differ. The point is…know who you’re talking to, know how they behave, know what they like, and deliver content using any number of social relationship management targeting tools that meets their expectations. If, however, you’re committed to a one-size-fits-all, “our content is for everybody” strategy (or even worse, a “this is what we want to put out and we expect everybody to love it” strategy), your content will miss the mark for more often than it hits. @mikestilesPhoto via stock.schng

  • Two different websites in one remote hosting

    - by Kor
    My client asked me that a website that is hosted in one server (and pointing there through a domain) should also be accessed (into a specific directory) from another domain, which is not pointing there. For example: http://www.foo.com, hosted at GoDaddy, with the full website http://www.bar.com, hosted at Bluehost, needs to access http://www.foo.com/bar, as if it was the http://www.bar.com's root. So, if anybody enters through http://www.bar.com, it should internally load http://www.foo.com/bar, without visually changing the url. I amb not sure if this is possible using .htaccess or anything like this. Could anybody show me some light? Thanks in advance

  • How does one unit test an algorithm

    - by Asa Baylus
    I was recently working on a JS slideshow which rotates images using a weighted average algorithm. Thankfully, timgilbert has written a weighted list script which implements the exact algorithm I needed. However in his documentation he's noted under todos: "unit tests!". I'd like to know is how one goes about unit testing an algorithm. In the case of a weighted average how would you create a proof that the averages are accurate when there is the element of randomness? Code samples of similar would be very helpful to my understanding.

  • GLSL, all in one or many shader programs?

    - by stjepano
    I am doing some 3D demos using OpenGL and I noticed that GLSL is somewhat "limited" (or is it just me?). Anyway I have many different types of materials. Some materials have ambient and diffuse color, some materials have ambient occlusion map, some have specular map and bump map etc. Is it better to support everything in one vertex/fragment shader pair or is it better to create many vertex/fragment shaders and select them based on currently selected material? What is the usual shader strategy in OpenGL or D3D?

  • How do I update wine in one wineprefix?

    - by Steve
    Does anyone know how I can go about updating the version of wine that one prefix uses without self-destructing everything in it? I want to bring it from 1.4 to 1.5.5 - I read on a forum that someone got the microphone working in Rosetta Stone with Ubuntu 12.04 and wine 1.5.5. Thanks for any guidance on this matter. :) http://ubuntuforums.org/showpost.php?p=11984993&postcount=20 Update: Issue resolved. Thanks to zuberuber I was able to approach the issue in a different light. :) I made a new prefix called "test" in PlayOnLinux. I compared the new prefix with the Rosetta prefix. It contained a PlayOnLinux.cfg file along with the reg files. It contained: ARCH=x86 VERSION=1.5.0 I copied this over to the Rosetta prefix and adjusted it: ARCH=x86 VERSION=1.4.1 After doing that, I was able to change it from 1.4.1 to 1.5.0. I confirmed it in the prefix's winecfg's About tab.
