  • XNA 2D Rotated Rectangle Collision Response

    - by Kyle Uithoven
    I am using Rotated Rectangles which collide using the Separating Axis Theorem and they work perfectly fine for collision detection using Intersects and Contains. However, I am starting to use faster objects in my game now and there is the issue of the two object overlapping during collision due to their higher velocities. I would like to do a collision response where I find out how much they are overlapping in the X and Y and put position them outside of each other. I would like to use something like this: http://go.colorize.net/xna/2d_collision_response_xna/index.html. But I am having some issues trying to adapt this to handle the rotation of the bounds. Is this possible? Are there any resources out there that I can look at?

  • Windows Embedded Compact 7 in Padua

    - by Valter Minute
    Yesterday I did a presentation about Windows CE at the University of Padua Even if the picture seems to suggest that I just showed and empty slide, I illustrated the new features of the OS and did a quick demo of Silverlight for Windows Embedded on Windows Embedded Compact 7 (I’ve to get used to this new name), showing the new tools that provide a better integration between Expression Blend and Visual Studio for the development of Silverlight applications (I hope to be able to write more on this topic soon!). The Operating System was running on some real hardware (TI OMAP3530 evaluation board) and many people had a chance to interact with the new customizable shell. Most of the 60 people attending were still awake at the end of the one hour and a half session, and some of them even asked questions! I would like to thank all the people attending and all the people of Arrow, Fortech Embedded Labs and the University of Padua that made this event possible and provide me the tool and the time to do this presentation.

  • Which software should I use on Ubuntu to create a Windows XP LiveUSB? [closed]

    - by user92241
    Possible Duplicate: How to create Windows XP LiveUSB using Ubuntu to replace it Since many programs that I need only work on XP, I need to install Windows XP on my 2 laptops but I can't use an optical drive, which makes using a USB the only option. If it helps, I can tell you that I used to have Vista and Windows 7 on my 2 laptops but I clean installed Ubuntu 12.04 on one, and Lubuntu on the other. Also I have no trace of Windows left on any of my laptops, when I bought my laptops they came without a Windows CD, so I only had a 20GB partition on my hard drives (which I formatted when I clean installed Ubuntu and Lubuntu.) Also, I have no problem with clean installing Windows XP and the reinstalling Ubuntu/Lubuntu so I can dual boot. Thanks! Edit: I have a ISO file ready, on a USB.

  • usb keyboard stopped working in terminal window after update from 13.04 to 13.10

    - by Jim
    When I start the computer, I am logged in automatically. Using the keyboard, I type Ctrl+Alt+t, which brings up a terminal window, just like it should; however, nothing happens when I attempt to type into the terminal. If I change over to the guest account, I can type into the terminal, but (different problem here, I'll ask it separately unless someone is kind enough to answer it here) my password doesn't work for sudo or anything else. Elsewhere I read that Language support could fix it, but that won't accept my password either - and no, I haven't changed it lately. Also, my Plex Media Server seems to have disappeared. I'll re-install everything if necessary, but I sure would rather avoid that if possible

  • Ubuntu on galaxy note II

    - by user131918
    I recently bought Samsung Galaxy Note II on android 4.1. It was my idea to try to turn it into a pc and I bought a micro-keyboard for the same purpose. I had hoped there would be an app for OpenOffice, but there isn't. Now i see that ubuntu may be installed on smart phones. I already have ubuntu - including OpenOffice - on my laptop. My question is: is it possible to install ubuntu to galaxy note II, and if so, does it include office programs and other ubuntu programs? Thank You And thank you so much for an alternative to Microsoft.

  • Database in the cloud?

    - by Jlouro
    Some of my recent clients are asking for remote connections to the office server, for standalone work, etc, in winForm applications. Since the concept of the web is remote connection to a server both of data and resources, it should be possible to place both of this in cloud and have the winForm apps connect to it as if web Apps. As any one tested this, is working like this? Is it fast enough? Is it secure? What is the best cloud host for this type of work ?

  • Tell the kernel to strongly cache a particular directory

    - by silviot
    This question is a rephrasing of Optimizing EXT4 performance. I have a directory that contains build files, most very small, but totaling 5.6G. I usually access the same subset of files (some thousands, for some tens of megabytes) over and over again. The subset changes daily (different projects, different versions of libraries). What takes longer when I use it seem to be disk seeks. For example if I do a du twice the second time it takes as much time as the first, and disk activity is similar. Ideally I'd like to tell the kernel to allocate X Mb to the metadata and Y to data in the folder, like the options for nfs cache. Is it possible in some way, other than mounting nfs from localhost and caching it to a ramdisk?

  • How to enable home directory encryption for a particular user?

    - by Ivan
    I prefer to have a dedicated "administrator" user for technical purposes and that was one I've set up during installation. I've also refused to encrypt the home folder of the user. Now, as I've added a user account for my actual work usage I want my (but not the "administrator") home folder to be encrypted. How to turn this on? If it is not possible then how to enable encryption for all users home directories on a system already installed? I've found questions and answers about how to disable it but am not sure how to enable it.

    - by user70122
    I want to deploy my PHP and Ajax based Dating website to multiple physical servers. Does anyone know the method. Is there possible any method to save the files and setting (and also the user input), on all of the physical server, so that the servers do the following jobs. Servers used as a network, speeding up the process giving a robust thing to the end user.

Does anyone know about some online course, or some comprehensive tutorials about this topic ?

  • How hard it will be for the programmer to learn MS SSRS adn SSIS [closed]

    - by user75380
    I have a programming background in php/python/java for 5 years and I know MySQL and PostgreSQL. Currently in our company the MSQL Business Intelligence person is leaving his job in 4 months. I am thinking of trying to go to his place, at least try as I want to move in Business Intelligence field in SSRS and SSIS. I just want to know that is it possible for me to get my head around those things in 4 months because I have no idea how they work and how hard it will be for me to pick up those things. Can I do that? I just want to know from experienced people if I can move towards that field? At least how should I start? In my area there are shortages of person, so once I know the stuff I can get into junior jobs easily but I want to know from experienced people.

  • 1 year to learn as much as possile - How would you plan this time?

    - by user1189880
    I have been messing around with web development and programming in general for a couple of years now, working in web development agencies and the like. I have now decided that I want to move to more general programming and do this permanently and as a career and have set myself a goal of 1 year to learn as much as I can before I go out and find a 'proper' job as a programmer. Do any programmers out there have any opinions on how this time should be split and what the most important things to focus on will be over the year. The languages I will be focusing my learning on are: c, php, python and go - all of which i have varying degrees of familiarity with. The ultimate goal here is to gain as good as foundation as possible and to be of a good enough level to interview successfully for a decent company.

  • Do 3d assets cost a lot more than 2d?

    - by Balls
    I'm planning to create a game on my own and will most likely hire an artist in the future. I just want to know if making a game in 2d will a lot cheaper than making it on 3d? Here's my plan: If it will be a 2d game.. I'll probably make a platform game. More like a Braid level of graphics. If it will be a 3d game.. Closest of graphics I'll ask for will be far cry 1 or if possible oblivion. So any thoughts? I'm funding all of it on my own. It will be my first game but will use maybe an engine around if it will be a 3d game. If 2d, I have my own engine lying around here. Thank you, Balls

  • Search for odt files without indexing

    - by josinalvo
    I am looking for: a way to search inside odt files (i.e. search for contents, not name) that does not require any kind of indexing that is graphical and very user-friendly (for a relatively old person, who does not like computers much) I know that it is possible to have 1) and 2): for x in `find . -iname '*odt'`; do odt2txt $x | grep Query; done works well enough, and it's pretty fast. But I wonder if there is already a good solution that does this with a GUI (or can be adapted to do this easily)

  • Result of the "How long do you wait before Solaris 11 gets on your prod systems?"

    - by nospam(at)example.com (Joerg Moellenkamp)
    I just removed the poll at 10:52, so this is the final result: My conclusions out of it: While the removal of UltraSPARC I to VI+ support in Solaris 11 may hit some of the people voting in the categories "Wait?" to "6 month", most of the users keep Solaris 10 running on their existing system anyway or migrate that late that even the newest system have reached their end-of-service-live or are near of it, so a migration doesn't sound that feasible. So i assume Product Management was right with their decision to remove the support in order to make the feature i can't talk of possible, as i don't think that many of the early migrators are still using the system in question, as most systems have reached EOSL. Didn't thought that there would be people waiting three years and more ...

    This is cool. Get this Java ME app to download your hotel key to your mobile phone without having to check in at the front desk.

Nice. Just don't accidentally drop your cell phone in the toilet. You'll be sleeping in the restroom if you do. Just sayin'. Hinkmond

  • Rendering only a part of text FTGL, OpenGL

    - by Mosquito
    I'm using FTGL library to render text in my C++ project. I can easily render text by using: CFontManager::Instance().renderWrappedText(font, lineLength, position, text); Unfortunately there is a situation in which this Button which displays text, is partly hidden because of resizing container in which it is situated. I'm able without any problem to draw Button's background to fit the container, but I've got a problem with doing the same with a text. Is it possible to somehow draw only text for given width and the rest just ignore? This is a screen which presents my problem: As you can see, the Button "Click here" is being drawn properly, but I can't do the same with "Click here" text.

  • Getting web results URLs in millions [closed]

    - by tereško
    I looked at all sites of SO and couldn't find any suitable to ask this question but posting here as nearest match to scenario After 1 months research I basically give up on getting all URL's from a search results programmatically, I looked at Google Search API to find a way to get millions of search results "URL's" to be specific to a text file or something relative but no success, but I am 100% there must be a way or trick of doing it. Real Question : Is there anyway programmatically or manually I can get 1000+ search results (URLs using search query e.g. "Apple" returns million of results on google and I want as much as possible URLs of them results in a text file)

  • Search Result Organization

    - by Vecta
    I'm creating an AJAX live search on a website I'm working on. Users will select values from a few dropdowns and a list of products will be returned based on what they select. Some possible fields would be: color, model, make, etc. What type of organization of search results do users tend to find most useful? Is it better to lump them all together (alphabatized) or is it more useful to lump them together by make? In the past I've tended to group them by "make" but I'm not concerned that this will continually force some items with a make toward the end of the alphabet always to the bottom of the list. Any tips are greatly appreciated.

  • Alternatives to using cookies?

    - by theclueless1
    Whate are alternatives to using cookies/client-side storage for a PHP/MySQL based site on Apache. Scenario/Requirements: I want to try using some anti-bot code to prevent specific scrapers etc. from accessing the site. I would like to run this code before launching the rest of the site (before DB access etc.). I don't want to constantly run the same code on every page-load after a visitor has passed the initial check. I'd like to avoid the use of Cookies/Client side storage if at all possible. The only solution I can currently think of is to write files to the server based on the visitors IP/UA, or to write a list of them to a single file. Yet this has the limitation of multiple users through a proxy/same connection, etc ... So, any ideas/suggestions? Or am I simply over working the issue?

  • xubuntu keyboard application shortcuts not working

    I am using the latest Xubuntu 13.04 with Xfce 4.10. I have issues while setting "Application Shortucts' from 'Settings Manager Keyboard Application Shortcuts'. Not all custom keyboards shortcuts, which I have added, work. Some do, some don't. Example the command 'xdotool key XF86AudioPause' works perfect from cmdline, but not when I assign this as a shortcut to some key, say 'F11'. Have tried to Google about this, but found nothing. Kindly help. If possible, kindly provide me a cmdline way to set a keyboard shortcut

  • How do I know if a particular build has a particular version control change in it?

    - by carleeto
    Let's say I have a build. I need to know if a particular changelist/commit is present in that build. How would I solve this problem? I can think of a couple of possible approaches: 1) Add the changelist number into the binary so that I can look somewhere in the GUI and know what the changelist number is. I can then use this information to determine if the change I'm interested in is within that build. 2) Tag version control using some string that uniquely identifies that build. What unique string would I use? Is either of these two better? Are there any other better approaches? The solution would have to work for both Mac and Windows builds.

  • How to achieve 'Activities' in Unity?

    - by Ralf Hersel
    I like the concept of an activities centric desktop and I wonder if this can be achieved in Unity. For me, an activity is a couple of applications that belong to the same subject, like 'photo manipulation', 'software development', 'office work', 'social activities', 'music and video'. I would like to utilize the virtual desktops to arrange applications that belong to the same activity group. Example: Desktop 1 contains all applications that belong to 'office work' Desktop 2 contains all applications that I need for 'software development' Desktop 3 contains all applications that I usually need for 'photo works' Therefore I would like to give names to the virtual desktops that reflect their purpose. And I would like Unity to auto-start the required applications when I start my computer or when I switch to one of the virtual desktops. Is this possible with Unity (or any other desktop)?
