  • Make the Firefox Awesome Bar Semi-Transparent Like Google Chrome

    - by Matthew Guay
    Would you like to make the Firefox Awesome Bar drop-down menu semi-transparent like in Google Chrome?  Here’s a quick trick that can make your Firefox Awesome Bar a bit more awesome. When you type an address or search query into the address bar in Google Chrome, the drop-down list of history and search suggestions that appears is slightly transparent.  Nothing extreme, but it adds a nice touch. Firefox’s Awesome bar, on the other hand, is fully opaque by default. We can change that with a simple change.  Exit Firefox, then open your Firefox profile folder by entering the following in the address bar in Explorer or in the Run command: %appdata%\Mozilla\Firefox\Profiles\ Open the default folder, and then open the Chrome folder in it. Now, open the userChrome.css file in an editor such as Notepad.  If you do not have a userChrome.css file, open the userChrome-example.css file instead. Now, add the following to the end of the file: #PopupAutoCompleteRichResult[type="autocomplete-richlistbox"]{    opacity: 0.9 !important;} You can change the opacity value, but 0.9 seemed the closest to Chrome’s transparency while keeping the text readable. Save the file as userChrome.css in that same folder.  If you’re editing with Notepad, make sure to select to save as All Files so the file won’t be saved with a .txt extension. Open Firefox, and now your Awesome Bar’s drop-down list will be transparent.  Actually, it may look even more awesome than Google Chrome’s address bar! Conclusion With this simple trick, you can make your Firefox Awesome bar a bit more awesome.  With tweaks like this, it’s no wonder Firefox is still so popular.

  • 8 Things You Didn’t Know You Could Do In Windows 7's Task Manager

    - by Chris Hoffman
    The Windows Task Manager is often used for troubleshooting – perhaps closing an application that isn’t working properly or monitoring system resource usage. However, there’s a lot more you can do with Windows 7’s Task Manager. To quickly open the Task Manager, right-click your taskbar and select Start Task Manager. You can also press Ctrl+Shift+Esc to quickly launch the Task Manager with a keyboard shortcut. Windows 8 may have a great new task manager, but Windows 7’s is still useful.

  • Best way of storing voxels

    - by opiop65
    This should be a pretty easy question to answer, and I'm not looking for how to store the voxels data wise, I'm looking for the theory. Currently, my voxel engine has no global list of tiles. Each chunk has it's own list, and its hard to do things like collision detection or anything that may use tiles that are outside of its own chunk. I recently worked on procedural terrain with a non voxel engine. Now, I want to start using heightmaps in my voxel engine. But, I have a problem. If each chunk has its own list, then it will be pretty difficult to implement the heightmaps. My real question is, is should I store a global list of voxels independent of the chunks? And then I can just easily perform collision detection and terrain generation. However, it would probably be harder to do things such as frustum culling. So how should I store them?

  • The joomla 'create a template' tutorial

    - by ryan
    Hello all, Ive recently downloaded joomla using an instant download option, and now im looking to create my own templates, so i went to http://www.siteground.com/tutorials/joomla15/joomla_create_template.htm and Im trying to follow the tuturial but ive failed at the first hurdle... where it says "First, open the "templates" directory in your Joomla installation. Then create a subfolder in it named "tutorial_template". All the files of your template will reside in it." The problem is I have no clue how to do this, where is the directory to start with?? the only thing I know how to get up is the administrators screen, in which I have to choose one of the stock templates, which would be great if I didnt care about my own designs...but obviously im looking to have my own html and css coding used instead. How do I find where the folders are and how do I open them? Im sorry if its a bit of a dumb question but im so confused..so early on. Thanks in advance. Ryan

  • Advice for good web server development setup.

    - by John Berryman
    A month or so ago I created my first LAMP stack and implemented a simple web site that exercised each letter in that acronym. However my development setup was much less than ideal. I don't really have a local test server, but instead I was writing all of my CGI scripts in vim while ssh'ed into the remote machine as root. Now I intend to start more serious development. Question: What is a good setup so that development goes as easily as possible? I would like to understand what is available to me along the lines of an IDE, subversion (or alternatives), uploading and downloading content, and just best practices. I'm pretty new at all of this. Also, feel free to point me at good websites. There's plenty of websites, but only people who are already heavily developing web content are able to quickly determine if they are good websites.

  • Lync Server 2010

    - by ManojDhobale
    Microsoft Lync Server 2010 communications software and its client software, such as Microsoft Lync 2010, enable your users to connect in new ways and to stay connected, regardless of their physical location. Lync 2010 and Lync Server 2010 bring together the different ways that people communicate in a single client interface, are deployed as a unified platform, and are administered through a single management infrastructure. Workload Description IM and presence Instant messaging (IM) and presence help your users find and communicate with one another efficiently and effectively. IM provides an instant messaging platform with conversation history, and supports public IM connectivity with users of public IM networks such as MSN/Windows Live, Yahoo!, and AOL. Presence establishes and displays a user’s personal availability and willingness to communicate through the use of common states such as Available or Busy. This rich presence information enables other users to immediately make effective communication choices. Conferencing Lync Server includes support for IM conferencing, audio conferencing, web conferencing, video conferencing, and application sharing, for both scheduled and impromptu meetings. All these meeting types are supported with a single client. Lync Server also supports dial-in conferencing so that users of public switched telephone network (PSTN) phones can participate in the audio portion of conferences. Conferences can seamlessly change and grow in real time. For example, a single conference can start as just instant messages between a few users, and escalate to an audio conference with desktop sharing and a larger audience instantly, easily, and without interrupting the conversation flow. Enterprise Voice Enterprise Voice is the Voice over Internet Protocol (VoIP) offering in Lync Server 2010. It delivers a voice option to enhance or replace traditional private branch exchange (PBX) systems. In addition to the complete telephony capabilities of an IP PBX, Enterprise Voice is integrated with rich presence, IM, collaboration, and meetings. Features such as call answer, hold, resume, transfer, forward and divert are supported directly, while personalized speed dialing keys are replaced by Contacts lists, and automatic intercom is replaced with IM. Enterprise Voice supports high availability through call admission control (CAC), branch office survivability, and extended options for data resiliency. Support for remote users You can provide full Lync Server functionality for users who are currently outside your organization’s firewalls by deploying servers called Edge Servers to provide a connection for these remote users. These remote users can connect to conferences by using a personal computer with Lync 2010 installed, the phone, or a web interface. Deploying Edge Servers also enables you to federate with partner or vendor organizations. A federated relationship enables your users to put federated users on their Contacts lists, exchange presence information and instant messages with these users, and invite them to audio calls, video calls, and conferences. Integration with other products Lync Server integrates with several other products to provide additional benefits to your users and administrators. Meeting tools are integrated into Outlook 2010 to enable organizers to schedule a meeting or start an impromptu conference with a single click and make it just as easy for attendees to join. Presence information is integrated into Outlook 2010 and SharePoint 2010. Exchange Unified Messaging (UM) provides several integration features. Users can see if they have new voice mail within Lync 2010. They can click a play button in the Outlook message to hear the audio voice mail, or view a transcription of the voice mail in the notification message. Simple deployment To help you plan and deploy your servers and clients, Lync Server provides the Microsoft Lync Server 2010, Planning Tool and the Topology Builder. Lync Server 2010, Planning Tool is a wizard that interactively asks you a series of questions about your organization, the Lync Server features you want to enable, and your capacity planning needs. Then, it creates a recommended deployment topology based on your answers, and produces several forms of output to aid your planning and installation. Topology Builder is an installation component of Lync Server 2010. You use Topology Builder to create, adjust and publish your planned topology. It also validates your topology before you begin server installations. When you install Lync Server on individual servers, the installation program deploys the server as directed in the topology. Simple management After you deploy Lync Server, it offers the following powerful and streamlined management tools: Active Directory for its user information, which eliminates the need for separate user and policy databases. Microsoft Lync Server 2010 Control Panel, a new web-based graphical user interface for administrators. With this web-based UI, Lync Server administrators can manage their systems from anywhere on the corporate network, without needing specialized management software installed on their computers. Lync Server Management Shell command-line management tool, which is based on the Windows PowerShell command-line interface. It provides a rich command set for administration of all aspects of the product, and enables Lync Server administrators to automate repetitive tasks using a familiar tool. While the IM and presence features are automatically installed in every Lync Server deployment, you can choose whether to deploy conferencing, Enterprise Voice, and remote user access, to tailor your deployment to your organization’s needs.

  • teamviewer in "client only" mode

    - by Tommy
    I have a remote PC with the teamviewer on it. I want to use my local teamviewer installation only for connecting to that remote PC, and I don't want any services (teamviewerd) running on my local Ubuntu 14.04. I've tried to disable the service by doing sudo teamviewer --daemon disable but after that I'm not able to connect to the remote PC, because teamviewer reports an error "The Teamviewer daemon is not running!" on start, and I'm not able to access the gui. Is there a way to connect to the remote PC with teamviewer with no teamviewerd running?

  • Mathematica 8 crashes Ubuntu 13.10

    - by Georgy Ivanov
    I have Mathematica 8 installed on my Ubuntu laptop since 2011. I updated Ubuntu several times, and experienced no problems with Mathematica. It also worked smoothly after I updated Ubuntu to 13.10 (it worked for sure for a week after update). When I tried to start Mathematica today by executing a .sh-file, the screen went black, I was logged out from the session and thrown back to the login screen. Typing mathematica in the terminal produced the same effect. Typing mathematica -cleanstart or mathematica -mesa did not help. Starting Gnome session with or without effects did not help Launching mathematica under another user account did not help. I still can run text-only version of mathematica by typing math in the terminal. I don't remember making any changes to my configuration except for installing updates. Is there any quick way to fix this behavior? How can I know which component exactly crashed? Where should I look for crash logs?

  • Gain Quick Access to the Cache in Firefox

    - by Asian Angel
    Are you looking for a quick and simple way to view the contents of the cache in Firefox? Then you will definitely want to see how easy it can be using the CacheViewer extension. Note: CacheViewer is a front-end app for easily accessing and searching the memory cache. Before Viewing the cache in Firefox using “about:cache” provides some information about the contents but may not be the most efficient method available for some people. CacheViewer in Action Once you have installed the extension there are three easy ways to access your new cache viewer. The first is using the “CacheViewer Command” available in the “Tools Menu” and the second is using the keyboard shortcut “Ctrl + Shift + C”. The third way is by adding a “Toolbar Button” to your browser’s UI. All three work equally well…choose the method that best suits your personal needs. When you access the “CacheViewer Window” this is what it will look like. You may decide to resize it and move (or hide) some of the columns for the best viewing. You can easily scroll through the cache contents and preview images if desired as shown here. If you keep the “CacheViewer Window” open you can refresh it as you browse using the “Refresh Button” in the lower right corner. This is a nice, quick, and very simple way to access the cache on demand and save items to your hard-drive if desired. Note: The “CacheViewer” can also be set to open in a new tab instead (see “Options”). Options Choose whether “CacheViewer” opens in a separate window (default) or in a new tab. Conclusion If you want a quick and simple way to view the cache in Firefox then the CacheViewer extension is just what you have been looking for.

  • Code refactoring with Visual Studio 2010 Part-2

    - by Jalpesh P. Vadgama
    In previous post I have written about Extract Method Code refactoring option. In this post I am going to some other code refactoring features of Visual Studio 2010.  Renaming variables and methods is one of the most difficult task for a developer. Normally we do like this. First we will rename method or variable and then we will find all the references then do remaining over that stuff. This will be become difficult if your variable or method are referenced at so many files and so many place. But once you use refactor menu rename it will be bit Easy. I am going to use same code which I have created in my previous post. I am just once again putting that code here for your reference. using System; namespace CodeRefractoring { class Program { static void Main(string[] args) { string firstName = "Jalpesh"; string lastName = "Vadgama"; Print(firstName, lastName); } private static void Print(string firstName, string lastName) { Console.WriteLine(string.Format("FirstName:{0}", firstName)); Console.WriteLine(string.Format("LastName:{0}", lastName)); Console.ReadLine(); } } } Now I want to rename print method in this code. To rename the method you can select method name and then select Refactor-> Rename . Once I selected Print method and then click on rename a dialog box will appear like following. Now I am renaming this Print method to PrintMyName like following.   Now once you click OK a dialog will appear with preview of code like following. It will show preview of code. Now once you click apply. You code will be changed like following. using System; namespace CodeRefractoring { class Program { static void Main(string[] args) { string firstName = "Jalpesh"; string lastName = "Vadgama"; PrintMyName(firstName, lastName); } private static void PrintMyName(string firstName, string lastName) { Console.WriteLine(string.Format("FirstName:{0}", firstName)); Console.WriteLine(string.Format("LastName:{0}", lastName)); Console.ReadLine(); } } } So that’s it. This will work in multiple files also. Hope you liked it.. Stay tuned for more.. Till that Happy Programming.

  • How to code UI / HUD in Entity System?

    - by Sylpheed
    I think I already got the idea of the Entity System inspired by Adam Martin (t-machine). I want to start using this for my next project. I already know the basic of Entity, Components, and Systems. My problem is how to handle UI / HUD. For example, a quest window, skill window, character info window, etc. How do you handle UI events (eg. pressing a button)? These are stuff that doesn't need to be processed every frame. Currently, I'm using MVC to code UI but I don't think that'll be compatible for Entity System. I've read that Entity System is embedded on a larger OOP. I don't know if UI is outside of ES or not. How do I approach this one?

  • Questions about an Engine Java

    - by CJ Sculti
    so I am going to start developing Java games (3D) but I have a few questions. So I dont know if I should use an engine or make my own. I feel like I am "cheating" if I use an engine to make my game. Is it frowned upon in the game developing world? What are some advantages and disadvantages to using an engine for my game and is it really that much harder to make my own engine? I know that engines have built in models and textures with easy drag and drop interfaces, would I have any of that if I were to code my own engine? Thanks guys.

  • How can I troubleshoot flash player/hardware conflict?

    - by sparthikas
    OBJECTIVE: Have a web browser on my Ubuntu install that can play youtube and hulu videos. Also would like to understand problem so that I can fix it again if I change software. Workarounds welcome, technical understanding and solution preferable. SYMPTOMS: Flash does not run - cannot make the right-click menu appear, an empty box is where video should be, changes to black box when hovering over other links. The "The Adobe Flash plugin has crashed" message does not appear with its sad lego face. cannot activate proprietary graphics driver - causes system to reboot to a prompt. SOLUTIONS TRIED: Replaced OS (tried slackware 13.37, fedora 17, linuxmint 13 maya, gentoo, lubuntu, and even winXP. lubuntu confirmed to work, don't remember how much tweaking, if any, this required. Slack, fedora, mint, and gentoo all failed to run flash just like ubuntu) many reinstalls of flash player via different methods, including cleaning up old installs first, also tried gnash and lightspark. replaced graphics card (replaced HIS IceQ Radeon HD 4670 AGP with older GeForce 5700 LE no change in problem) flash does successfully work on winXP installation with Catalyst AGP hotfix driver applied, however I consider windows wholly unacceptable for web browsing due to lack of security. Lubuntu install also works, however I do not want to be tied down to just using Lubuntu on this computer. SYSINFO: Have latest versions of Ubuntu, Firefox, and Flash on fresh Ubuntu install. Using Gigabyte 7s748 motherboard with Athlon XP 2800+ and 3 GB of RAM with Radeon HD 4670 AGP card, also a Dell soundblaster live series sound card (due to malfunction of onboard sound on motherboard) Wired internet connection, Maxtor 6Y120L3 HDD, Sony DVD RW AW-Q170A, Dell M993s monitor. NOTES: I do not know if the graphics driver issue and the flash troubles are linked. Substitution of older graphics card having same flash troubles seems to suggest they aren't. My troubleshooting method is rather reductionist, consisting mainly of "replace things until you find out what was causing the error by process of elimination" only it seems that this must be a conflict which arises when software decides how to configure itself on my hardware. That is, I know the hardware can run Flash, and I know that on other systems the same software can too, but somehow the combination fails. Consequently I feel out of my depth. I will keep trying things off and on, but I have spent probably about 30 man-hours in the last 4 months working on this problem with no joy other than the lubuntu workaround. Any help will be appreciated, I will be checking back and posting updates. Any pertinent questions regarding me or my computer will be answered, outputs from config files can be accessed and posted (IDK which ones or what parts to post).

  • What have my fellow Delphi programmers done to make Eclipse/Java more like Delphi?

    - by Robert Oschler
    I am a veteran Delphi programmer working on my first real Android app. I am using Eclipse and Java as my development environment. The thing I miss the most of course is Delphi's VCL components and the associated IDE tools for design-time editing and code creation. Fortunately I am finding Eclipse to be one hell of an IDE with it's lush context sensitive help, deep auto-complete and code wizard facilities, and other niceties. This is a huge double treat since it is free. However, here is an example of something in the Eclipse/Java environment that will give a Delphi programmer pause. I will use the simple case of adding an "on-click" code stub for an OK button. DELPHI Drop button on a form Double-click button on form and fill in the code that will fire when the button is clicked ECLIPSE Drop button on layout in the graphical XML file editor Add the View.OnClickListener interface to the containing class's "implements" list if not there already. (Command+1 on Macs, Ctrl + 1 on PCs I believe). Use Eclipse to automatically add the code stub for unimplemented methods needed to support the View.OnClickListener interface, thus creating the event handler function stub. Find the stub and fill it in. However, if you have more than one possible click event source then you will need to inspect the View parameter to see which View element triggered the OnClick() event, thus requiring a case statement to handle multiple click event sources. NOTE: I am relatively new to Eclipse/Java so if there is a much easier way of doing this please let me know. Now that work flow isn't all that terrible, but again, that's just the simplest of use cases. Ratchet up the amount of extra work and thinking for a more complex component (aka widget) and the large number of properties/events it might have. It won't be long before you miss dearly the Delphi intelligent property editor and other designers. Eclipse tries to cover this ground by having an extensive list of properties in the menu that pops up when you right-click over a component/widget in the XML graphical layout editor. That's a huge and welcome assist but it's just not even close to the convenience of the Delphi IDE. Let me be very clear. I absolutely am not ranting nor do I want to start a Delphi vs. Java ideology discussion. Android/Eclipse/Java is what it is and there is a lot that impresses me. What I want to know is what other Delphi programmers that made the switch to the Eclipse/Java IDE have done to make things more Delphi like, and not just to make component/widget event code creation easier but any programming task. For example: Clever tips/tricks Eclipse plugins you found other ideas? Any great blog posts or web resources on the topic are appreciated too. -- roschler

  • Do You Develop Your PL/SQL Directly in the Database?

    - by thatjeffsmith
    I know this sounds like a REALLY weird question for many of you. Let me make one thing clear right away though, I am NOT talking about creating and replacing PLSQL objects directly into a production environment. Do we really need to talk about developers in production again? No, what I am talking about is a developer doing their work from start to finish in a development database. These are generally available to a development team for building the next and greatest version of your databases and database applications. And of course you are using a third party source control system, right? Last week I was in Tampa, FL presenting at the monthly Suncoast Oracle User’s Group meeting. Had a wonderful time, great questions and back-and-forth. My favorite heckler was there, @oraclenered, AKA Chet Justice.  I was in the middle of talking about how it’s better to do your PLSQL work in the Procedure Editor when Chet pipes up - Don’t do it that way, that’s wrong Just press play to edit the PLSQL directly in the database Or something along those lines. I didn’t get what the heck he was talking about. I had been showing how the Procedure Editor gives you much better feedback and support when working with PLSQL. After a few back-and-forths I got to what Chet’s main objection was, and again I’m going to paraphrase: You should develop offline in your SQL worksheet. Don’t do anything in the database until it’s done. I didn’t understand. Were developers expected to be able to internalize and mentally model the PL/SQL engine, see where their errors were, etc in these offline scripts? No, please give Chet more credit than that. What is the ideal Oracle Development Environment? If I were back in the ‘real world’ of database development, I would do all of my development outside of the ‘dev’ instance. My development process looks a little something like this: Do I have a program that already does something like this – copy and paste Has some smart person already written something like this – copy and paste Start typing in the white-screen-of-panic and bungle along until I get something that half-works Tweek, debug, test until I have fooled my subconscious into thinking that it’s ‘good’ As you might understand, I don’t want my co-workers to see the evolution of my code. It would seriously freak them out and I probably wouldn’t have a job anymore (don’t remind me that I already worked myself out of development.) So here’s what I like to do: Run a Local Instance of Oracle on my Machine and Develop My Code Privately I take a copy of development – that’s what source control is for afterall – and run it where no one else can see it. I now get to be my own DBA. If I need a trace – no problem. If I want to run an ASH report, no worries. If I need to create a directory or run some DataPump jobs, that’s all on me. Now when I get my code ‘up to snuff,’ then I will check it into source control and compile it into the official development instance. So my teammates suddenly go from seeing no program, to a mostly complete program. Is this right? If not, it doesn’t seem wrong to me. And after talking to Chet in the car on the way to the local cigar bar, it seems that he’s of the same opinion. So what’s so wrong with coding directly into a development instance? I think ‘wrong’ is a bit strong here. But there are a few pitfalls that you might want to look out for. A few come to mind – and I’m sure Chet could add many more as my memory fails me at the moment. But here goes: Development instance isn’t properly backed up – would hate to lose that work Development is wiped once a week and copied over from Prod – don’t laugh Someone clobbers your code You accidentally on purpose clobber someone else’s code The more developers you have in a single fish pond, the greater chance something ‘bad’ will happen This Isn’t One of Those Posts Where I Tell You What You Should Be Doing I realize many shops won’t be open to allowing developers to stage their own local copies of Oracle. But I would at least be aware that many of your developers are probably doing this anyway – with or without your tacit approval. SQL Developer can do local file tracking, but you should be using Source Control too! I will say that I think it’s imperative that you control your source code outside the database, even if your development team is comprised of a single developer. Store your source code in a file, and control that file in something like Subversion. You would be shocked at the number of teams that do not use a source control system. I know I continue to be shocked no matter how many times I meet another team running by the seat-of-their-pants. I’d love to hear how your development process works. And of course I want to know how SQL Developer and the rest of our tools can better support your processes. And one last thing, if you want a fun and interactive presentation experience, be sure to have Chet in the room

  • Issues with ganglia and upstart in 13.04

    - by theist
    I'm having an issue with ganglia-monitor and upstart. Just after installing it starts and it cannot be stopped. I tried to solve it following http://upstart.ubuntu.com/cookbook/#expect but I can achieve upstart to track the actual pid of gmond. Assuming the configuration of the init config is wrong i followed direcetions in http://upstart.ubuntu.com/cookbook/#how-to-establish-fork-count in order to try to fix it. As it states a count of 1 means "exec fork" stanza and 2 means "exec daemon" .... gmond gives a count of 8... And of course I can get it to track the actual PID. I haven't found a bug report or something like that. Is there something I missed ? Upstart seems to be failing and the worst thing is that upstart hangs on start/stop and I cannot even uninstall or reconfigure packages.

  • doubleTwist is an iTunes Alternative that Supports Several Devices

    - by Mysticgeek
    There are a lot of iTunes users out there, but unfortunately you can’t use it with all of your portable devices. Today we take a look at doubleTwist, which allows you to sync your media with a multitude of portable devices and easily share it as well. Note: You can run doubleTwist on Windows or Mac, and here we take a look at the Windows version. Install & Setup doubleTwist Download and install doubleTwist using the defaults in the wizard… Installation takes several moments and you’ll see the progress while it finishes up. After installation is complete, sign up for an account if you don’t already have one. If you do have an account you can login right away. Enter in your username, email address, and password then click Sign Up.   You’ll get an confirmation email and need to activate the account before you can sign in. Once you’re all signed up, launch doubleTwist and you’ll be ready to start using it. doubleTwist Music The default music store is Amazon MP3 store which might appeal to those of you who are tired of the iTunes music store. A lot of times the music is cheaper and available at higher bit rates. You can start searching for music in the Amazon Music Store and previewing songs. To purchase anything though you will need to sign into your Amazon account.   Under Playlists it allows you to import your playlists from iTunes and Windows Media Player, which is a handy feature if you don’t want to set them up again. Of course you can play your songs through the music player on your desktop. Devices One of the coolest things about doubleTwist is that it supports a lot of different portable media devices including iPod, BlackBerry, Windows Mobile, Android, PSP, Smartphones, and much more. Unfortunately for Zune users…there isn’t any support for the Zune of Zune HD yet. Here we have a Creative Zen attached and can sync songs, pictures, and podcasts. An HTC-S620 Smartphone running Windows Mobile… Even a simple USB drive will be recognized and you can transfer your media to it as well.   Podcasts Finding your favorite audio and video podcasts is easy with the search feature. You can easily manage and subscribe to podcasts in the subscriptions section.   You can watch the video podcasts directly in doubleTwist. Sharing Media Also you can share digital media with your friends or add it to Flickr and YouTube. You can send any pictures, videos, or music in your library to other people by dragging it over. You can email users individually… Or access contacts from your Gmail and Yahoo accounts. There is a limit to how much you can send of video podcasts… only the first 10 minutes. The person you send it to will get a link in their email that points to your My Feed page on the doubleTwist site.   There they can access the media you sent…in this example it’s a video podcast but you can share any media. Other Features Under My Profile you can change your avatar and personal information.   In Preferences you can choose where media is stored, its startup actions, podcast subscriptions, and manage device syncing. Conclusion It’s still in beta stage so expect some bugs, but overall doubleTwist is a solid media player that is easy to use with a clean interface. It’s simple and doesn’t try to do too much so is fairly easy on system resources. The main annoyance is it tries to catalog all of your media out of the box. Which may be alright for some users with smaller media collections, but very irritating to advanced users with large collections. Also there is currently no support for the Zune, but according to their forums, it’s on the way. At the time of this writing it’s in public beta and can be downloaded for XP, Vista, Windows 7 (32 & 64 bit), and Mac OSX. If you’re looking for an iTunes alternative that works with several different portable devices, you might want to give DoubleTwist a try.

  • Windows Embedded Compact 7

    - by Valter Minute
    I’m back from Seattle where I attended the MVP Summit and presented the Windows Embedded Compact 7 training materials during the Train The Trainer in Bellevue (many thanks to all the people attending and providing great suggestions to improve the materials!). The MVP summit was a great chance to discover new things about all the different technologies, to see old friends and meet new ones. The TTT location (Microsoft training facilities at Lincoln square in Bellevue) was great and here’s the landscape that the attendees could enjoy (partially ruined by my presence in the foreground!). In the meantime Windows Embedded Compact 7 has been released: http://www.microsoft.com/windowsembedded/en-us/evaluate/windows-embedded-compact-7.aspx You can download an evaluation version and start to discover its new features (SMP support, support for 3GBs of RAM, Silverlight for Windows Embedded tools, ARM v5,v6 and v7 compilers and many more…) and, maybe, decide to attend a training about it.

  • Sources (other than tutorials) on Game Mechanics

    - by Holland
    But, I'm not quite sure where I should start from here. I know I have to go and grab an engine to use with some prebuilt libraries, and then from there learn how to actually code a game, etc. All I have right now is some "program Tetris" tutorial for C++ open right now, but I'm not even sure if that will really help me with what I want to accomplish. I'm curious if there are is any good C++ documentation related to game development which provides information on building a game in more of a component model (by this I'm referring to the documentation, not the actual object-oriented design of the game itself), rather than an entire tutorial designed to do something specific. This could include information based on various design methodologies, or how to link hardware with OpenGL interfaces, or just simply even learning how to render 2D images on a canvas. I suppose this place is definitely a good source :P, but what I'm looking for is quite a bit of information - and I think posting a new question every ten minutes would just flood the site...

  • Will Ubuntu break my RAID 0 array?

    - by Chad
    I am upgrading an older machine today with new Motherboard, RAM, and CPU. Then I am going to do a fresh install of Ubuntu 64bit. Currently the old machine has an 80gb system drive, and a 4TB RAID 0 array. The old Motherboard has no SATA ports, so I used a SATA card. Ubuntu set up the old RAID array, will it still recognize the array on a newer machine? Are there any steps I should take to ensure the array isn't damaged? It's non-crucial data, but I would rather not start over if it can be avoided. Thanks.
