  • Web API Presentation at DC DNUG

    - by Steve Michelotti
    This Tuesday (July 19), I’ll be presenting the ASP.NET Web API at the DC DotNet Users Group. Abstract: Modern web applications have seen an explosion in Web API creation. Twitter, Facebook, Google, Azure, you name it – it is becoming essential to provide a Web API so that consumers can build applications and mashups on top of your services. Web 2.0 has shown a trend away from SOAP towards a REST architecture style. With the new ASP.NET Web API, Microsoft is now providing first-class support for HTTP services including tools to apply the richness of a REST architectural style. This demo heavy presentation will show how the new ASP.NET Web API will enable you to build rich HTTP services in a REST architectural style while leveraging custom media types, custom HTTP handlers, jQuery and more! The presentation will also cover new features of MVC 4 including Razor enhancements, Web Optimizations, and more.

  • can't chmod on external hard disk?

    - by G. He
    I have an USB3.0 external hard disk, partitioned to 3 NTFS partitions. When I plug the hard disk in, the 3 partitions automatically mounted under /media. So far so good. I can read and write to files, or mkdir, etc on these partitions. But I can't do chmod/chown on any of the files/directories on these partitions. The owner:group always myself, and the mode are always 700 for directories and 600 for files. I have another partition on internal harddisk also mounted. That partition works fine. I looked the output of mount command, the only difference between mount options is that there is one extra 'default_permissions' on the external hard disks. Anyway I can set the owner:group and mode on these files and directories.

  • Flash Player 11.5 et AIR 3.5 en betas : meilleur débogage pour les deux et support de Jelly Beans pour AIR

    Flash Player 11.5 et AIR 3.5 en betas Meilleur débogage pour les deux et support de Jelly Beans pour AIR Adobe vient de confirmer l'arrivée de la bêta de son Flash Player 11.5. Au menu de cette préversion, on notera surtout un nouvel outil de déboggage pour les développeurs ou la possibilité de partager la mémoire pour les ActionScript Workers. Si Adobe ne supportera plus la technologie dans le mobile, elle n'a cependant pas abandonné AIR dont la version 3.5 passe elle aussi en beta. Mieux, depuis que les runtimes d'Adobe partagent la même base il est possible de reprendre le code d'applications Rich Media pour les porter de Flash vers Air et inversement.

  • Ubuntu 12.04 x64 - Very slow response and sluggishness

    - by Murphy1138
    Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

  • How to write the path to a Windows shared folders address in terminal?

    - by user206996
    I want to permanently mount a few Windows shared folders. I googled that topic and found a lot of good answers, but with all the solutions I have a little problem: I believe I can't properly give an address of shared folder. I can find it following way: "Network" - "Windows Network" - "WORKGROUP_name" - "Computer_name" - and there is some folder i would like to mount. How can I write the path to the folders in terminal? UPD i can access needed folder throw address in location bar smb://server/ro/, but i try mount it by editing /etc/fstab file (using guide https://wiki.ubuntu.com/MountWindowsSharesPermanently) i get error mount error: could not resolve address for server: Unknown error PS in /etc/fstab : //SERVER/RO /media/server cifs username=user,password=pwd, uid=1000,iocharset=utf8 0 0

  • How to access the SD card through my Sony Ericsson Xperia Arc Phone?

    - by user16364
    I have a Sony Ericsson Xperia Arc phone and I cannot access its SD card through the USB cable provided. I have set the USB connection mode to MSC yet when I connect the phone to my computer I cannot see the SD card (or anything for that matter). The Disk Utility however, does see an SEMC Mass Storage device but it says that no media was detected. I have validated that the SD card works as I removed it from the camera and plugged it into a card reader and saw all the photos and files stored on it. I have validated that the phone works as I have connected it (in MSC mode) to my wife's Windows 7 computer. Can anyone please tell me how I can access the SD card on my phone.

  • Super slow and laggy?

    - by Mystogan
    I'm a native Windows user, running 7 Home Premium atm. In the past I installed Ubuntu 10 on my netbook I believe, but was a bit 'scared' by it. Anyways, I made a partition on my desktop pc, 100gb and installed Ubuntu 12.10 on it. It was pretty slow first thought it had to install updates or something, so I rebooted it. Now after the login it looks like everything freezes, I can move my mouse only ,but that's it! I can see my desktop and launcher, but the task bar doesn't display time and misc system info, only a black bar, I downloaded the android SDK pack and installed vlc media player before I rebooted. My computer info: - 1tb HDD - 8gb ddr3 ram - ATI Radeon 4890 videocard (1gb) - AMD Phenom 2 x4 black 3,2ghz CPU(64 bits) Thanks in advantage!

  • Huge 2d pixelized world

    - by aspcartman
    I would like to make a game field in a indie-strategic 2d game to be some a-like this popular picture. http://0.static.wix.com/media/6a83ae_cd307e45ffd9c6b145237263ac1a86be.jpg_1024 So every "pixel"(blocks) changes it's color slowly, sometimes a bright color wave happens, etc, but the spaces beetwen this pixels should stay dark (not to count shades, lightning and other 3rd party stuff going on). Units are going to be same "pixelized" and should position them-selfs according those blocks. I have some experience in game-developing, but this task seems not trivial for me. What approaches (shader, tons of sprites or code-render, i don't now) would you recommend me to follow? (I'm thinking of making this game using Unity Engine) Thanks everyone! :)

  • Resource Managers - Are they any good?

    - by The Communist Duck
    Hey. I've seen many a time in source code, things like this [well, this is more of a pseudo C++ idea of mine] type defshared_ptr ResourcePtr;// for ease ResourcePtr sound1 = resourceManager.Get("boom.ogg"); sound1-Play(); ResourcePtr sprite = resourceManager.Get("sprite.png"); I was just wondering how useful a class like this was, something that: Loaded media files Stored them in memory Did this at the start of a level - loading screen. Cleaned up Rather than having a system of: Resources are held by entities only, or loose. Responsible for own load into memory. The first is a 'manager' as such; something I feel indicates it's wrong to use. However, it allows for something like a vector of resource names to be passed, rather than having to scramble around finding everything that needs to be loaded.

  • La CNIL autorise les premiers ayants droits à collecter des adresses IP, la machine Hadopi se met en

    Mise à jour du 14.06.2010 par Katleen La CNIL autorise les premiers ayants droits à collecter des adresses IP, la machine Hadopi se met en marche Quelques semaines après la mise en place de l'équipe chargée de la mettre en oeuvre, la loi Hadopi semble prête à décoller. La CNIL (Commission nationale informatique et libertés) viendrait en effet d'autoriser les premiers ayants droits à collecter de manière automatisée les adresses IP d'utilisateurs soupçonnés de téléchargement illégal. Ceci leur permettra de ficher les contrevenants présumés pour ensuite en avertir Hadopi. Concrètement, c'est la société Trident Media Guard qui sera seule habilitée à collecter ces adresses pour le...

  • SEO Influenc search result per device class (mobile/desktop)

    - by user32224
    We're currently building a new responsive website and while working on the site map figured that we don't want to show certain sections on mobile devices. This can be easily done by hiding the navigation parts using css/media queries. However, trouble is that the hidden sites would still show up in search engines' search results. If a user happens to click on one of these links she might happen to see a badly formatted page as we'd use desktop/tablet only code to show images and video. Is there any way to "influence" to exclude certain pages if the search is done on a mobile device? Do search engines crawl pages once or with a device specific view twice? Could we set a noindex meta tag for a specific device class?

  • How to automount usb drive reliably without fstab

    - by user103279
    Hi I need a way to mount a usb drive without using fstab. I Cannot use fstab because the drive is not connected to my computer at boot. This causes an issue during any one off reboots because start up hang waiting for this device until a keyboard intervention to skip it. I cannot use my current script with just does mount /dev/sde1 /media/Backup because sometimes it changes to sdf. Consider this a server install. I can't use tools at the user or GUI level. I suppose the sum of my question is how to manually mount a usb drive from the commandline considering the reliability of the /dev/sd value isn't consistent. Thanks,

    i am a long time user of Ubuntu and this is the first time a such thing happens to me. I usually upgrade from a version to an other, but this time i wish to do a clean install. I want to totally remove my 12.04 and do a clean install of 12.10, i created a live USB then i restarted my computer to boot from USB, i got the following error: Product is covered by one or more of the following patents: US5,434,872, US5,732,894, (and many more) Under that i see: PCIe GBE Family Controller Series v2.38 Media test failiure Exiting PXE ROM And then it reboots I've searched a lot for an answer, i guess the problem is with something in my bios, but i didn't find a fix. I would really appreciate a fix for my problem. My laptop is a Toshiba p775 dual boot ubuntu 12.04 and windows 7.

    Windows 8 : Google sort son application de recherche Pour contrer Bing et préparer le terrain pour ses services concurrents de Microsoft La recherche par défaut de Windows 8 est bien évidemment Bing. On ne sait pas si la justice décidera de s'attaquer à cette application, comme elle l'a fait pour Internet Explorer ou le Media Player, mais on sait une chose : Google a déjà réagi.

  • How to setup complete file access and control on a network

    - by user96270
    I have a media server running ubuntu 12.04 and I want it setup so that any PC on the network (windows etc) has complete access to all files, folders etc with read, write, edit, copy to, copy from permissions. No need for security (IE no password or user name, just select it on the network and start editing). I have samba installed and personal file sharing is enabled but my windows PC cannot see it on the network. I already set up another server as I described but unfortunately I can't remember how or where I found the guides for it. Any on know of a guide that covers what I want?

  • A Safe Way to Allow Upload of All File Types?

    - by user34682
    By default WordPress restricts the file types that can be uploaded to /uploads using the default Media Manager. I know it is possible to manually extend the allowed file types. I also know it is possible to change functions.php to allow ALL file types to be uploaded. This restriction obviously exists for security concerns - e.g. someone could upload a harmful .exe Would it not be possible to allow secure upload of all filetypes by setting the permissions of the /uploads directory to prevent execution of any of its contents? Thus it wouldn't matter if someone uploaded a harmful file because it would not be executable on the server...

  • Ubuntu 13.10 is terrible

    - by user137017
    I was satisfied with 13.04. But when I upgraded to 13.10, I've had a lot of issues and some things just no longer work. To name a few problems: Can't change the brightness My laptop makes more noise than before It freezes more frequently (the kind that doesn't respond to ctr + alt + f2) Sometimes it boots up and and can't play any media files When running a full screened virtual machine in Workstation, ubuntu catches mouse at the edges When I have a VM opened in Workstation and I try to open up another, the first one gets powered off Most irritatingly, when I have a virtual machine running in full screen, every now and then the vm screen goes black and I have to switch to the host and come back 13.10 has offered nothing to compensate for these problems. I would like to get some advice about what I can do. Should I stick with 13.10 and hope the bugs will be fixed? Would a clean reinstall of 13.10 help? Btw, I'm giving some thought to trying other distros.

  • Can ping device from one computer and not the other

    - by Sean Duggan
    I've recently been assigned to work on a diagnostic program done in C++ which communicates with a piece of electronic equipment. Our normal scenario involves communicating via an RS232 interface, but I've been asked to make our program work over ethernet, source code having been done in Visual Basic. After much thrashing about trying to get the code to work and continuing to get 10049 Winsock errors when I tried to connect, I tried pinging the switch. From the computer the VB program is running on, I can see the switch via ping, nslookup, tracert, and pathping (I was going down the list of programs) and I can do this via URI or IP address. From my laptop, sending the same commands fails every time. They're both using the same network cable and the same USB-to-Ethernet device (I've been swapping them between tests) but one can see the switch and the other cannot. I'm working on the programming end, but the ping results makes me think that there might be a network issue stymieing me. wry grin I'm not much of a network guy, so I'm appealing to expert assistance. Both computers are running Windows XP if that helps. The connection is to an "IP-RS8" device which then connects to our VCU-C units. Each unit is accessible via URI or IP address on the desktop computer we usually have connected to the units (it's running the older VB program that I was asked to lift the networking code from). The connection is made via a USB-to-Ethernet adapter so as to leave the regular Ethernet port available for connecting to the company network. Hmm... come to think of it, I've probably been confusing the issue, talking about pinging "the switch" rather than indicating that it's the devices. My apologies. Communication is generally done with a DLL that uses Winsock functions to make queries for data from the VCU and then to receive. I'm failing when connecting. I haven't found anything on the firewall which should block these commands, but I'll keep poking. I don't know if it's potentially relevant, but on the desktop, the adapter maps to Local Area Connection 3 while on the laptop, it consistently maps to Local Area Connection 2.

  • MongoDB usage best practices

    - by andresv
    The project I'm working on uses MongoDB for some stuff so I'm creating some documents to help developers speedup the learning curve and also avoid mistakes and help them write clean & reliable code. This is my first version of it, so I'm pretty sure I will be adding more stuff to it, so stay tuned! C# Official driver notes The 10gen official MongoDB driver should always be referenced in projects by using NUGET. Do not manually download and reference assemblies in any project. C# driver quickstart guide: http://www.mongodb.org/display/DOCS/CSharp+Driver+Quickstart Reference links C# Language Center: http://www.mongodb.org/display/DOCS/CSharp+Language+Center MongoDB Server Documentation: http://www.mongodb.org/display/DOCS/Home MongoDB Server Downloads: http://www.mongodb.org/downloads MongoDB client drivers download: http://www.mongodb.org/display/DOCS/Drivers MongoDB Community content: http://www.mongodb.org/display/DOCS/CSharp+Community+Projects Tutorials Tutorial MongoDB con ASP.NET MVC - Ejemplo Práctico (Spanish):http://geeks.ms/blogs/gperez/archive/2011/12/02/tutorial-mongodb-con-asp-net-mvc-ejemplo-pr-225-ctico.aspx MongoDB and C#:http://www.codeproject.com/Articles/87757/MongoDB-and-C C# driver LINQ tutorial:http://www.mongodb.org/display/DOCS/CSharp+Driver+LINQ+Tutorial C# driver reference: http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial Safe Mode Connection The C# driver supports two connection modes: safe and unsafe. Safe connection mode (only applies to methods that modify data in a database like Inserts, Deletes and Updates. While the current driver defaults to unsafe mode (safeMode == false) it's recommended to always enable safe mode, and force unsafe mode on specific things we know aren't critical. When safe mode is enabled, the driver internal code calls the MongoDB "getLastError" function to ensure the last operation is completed before returning control the the caller. For more information on using safe mode and their implicancies on performance and data reliability see: http://www.mongodb.org/display/DOCS/getLastError+Command If safe mode is not enabled, all data modification calls to the database are executed asynchronously (fire & forget) without waiting for the result of the operation. This mode could be useful for creating / updating non-critical data like performance counters, usage logging and so on. It's important to know that not using safe mode implies that data loss can occur without any notification to the caller. As with any wait operation, enabling safe mode also implies dealing with timeouts. For more information about C# driver safe mode configuration see: http://www.mongodb.org/display/DOCS/CSharp+getLastError+and+SafeMode The safe mode configuration can be specified at different levels: Connection string: mongodb://hostname/?safe=true Database: when obtaining a database instance using the server.GetDatabase(name, safeMode) method Collection: when obtaining a collection instance using the database.GetCollection(name, safeMode) method Operation: for example, when executing the collection.Insert(document, safeMode) method Some useful SafeMode article: http://stackoverflow.com/questions/4604868/mongodb-c-sharp-safemode-official-driver Exception Handling The driver ensures that an exception will be thrown in case of something going wrong, in case of using safe mode (as said above, when not using safe mode no exception will be thrown no matter what the outcome of the operation is). As explained here https://groups.google.com/forum/?fromgroups#!topic/mongodb-user/mS6jIq5FUiM there is no need to check for any returned value from a driver method inserting data. With updates the situation is similar to any other relational database: if an update command doesn't affect any records, the call will suceed anyway (no exception thrown) and you manually have to check for something like "records affected". For MongoDB, an Update operation will return an instance of the "SafeModeResult" class, and you can verify the "DocumentsAffected" property to ensure the intended document was indeed updated. Note: Please remember that an Update method might return a null instance instead of an "SafeModeResult" instance when safe mode is not enabled.

  • So No TECH job so far.

    - by Ratman21
    O I found some temp work for the US Census and I have managed to keep the house (so far) but, it looks like I/we are going to have to do a short sale and the temp job will be ending soon.   On top of that it looks like the unemployment fund for me is drying up. I will have about one month left after the Census job is done. I am now down to Appling for work at the KFC.   This is type a work I started with, before I was a tech geek and really I didn’t think I would be doing this kind of work in my later years but, I have a wife and kid. So I got to suck it up and do it.   Oh and here is my new resume…go ahead I know you want to tare it up. I really don’t care any more.   Scott L.
