• What is the best book for the preparation of MCPD Exam 70-564 (Designing and Developing ASP.NET 3.5 Applications)?

  - by Steve Johnson

  Hi all, I have seen a couple of questions like this one and scanned through the answers but somehow the replies were not satisfactory or practical. So i wondered maybe people who have gone through it and may suggest a better approach for the preparation of this exam. Goal: My goal is actually NOT merely to pass that exam. I intend to actually master the skill. I have been into asp.net web development for approximately 1.5 years and I want to study something that really improves "Design and Development Skills" in Web Development in general and asp.net to be specific which i can put to use and build upon that. Please suggest a book that teaches professional Asp.Net design and development skills and approaches to quality development by taking through practice design scenarios and their solutions and through various case studies that involve design problems and their implemented solutions. Edit: I have found the Micorosoft training kits to be fairly interesting and helpful as these tend to increase knowledge. I have utilized a lot of things after getting a good explanation of things from the training kits. However, as far as Microsoft Training Kit for 70-564 is concerned, there are not a lot of good reviews about it. What i have read and searched on the net , the reviews on amazon and various forums, stack-exchange and experts-exchange, were more inclined to the conclusion that "Microsoft Training Kit for Exam 70-564 is not good. Its is not good as compared to other kits from Microsoft, like as compared to the training kit of Exam 70-562 or others." So i was looking for a proper book containing examples from practical world scenarios and case studies from which i can not only learn but also master the skills before wasting money of Microsoft Training Kit for Exam 70-564. Waiting for experts to provide a suitable advice.

• Sound leaks from speaker even when headphones are inserted

  - by instantsetsuna

  I've a Dell Optiplex 960 (which I presume has a speaker inside the tower). This speaker is normally in use whenever I play music (lets call this "tower speaker"), and when I insert my headphones in the 3.5mm jack (of the tower), the tower speaker stops and the music is played through the headphones (an obvious thing to happen). But sometimes, the tower speaker starts playing the music even when the headphones are inserted! So, the music is played through both of them! This gets quite embarrassing. So, my question is - Is there a way to turn off this "tower speaker"? EDIT : I'm using Windows XP

• How do I make apt-get install commands not display every package that is installing?

  - by rajlego

  When I install something on terminal, it often shows me a few things for status. For one, it shows download rate (which is fine). However, when I install something, it can display Unpacking libgranite2:amd64 (0.3.0~r732+pkg64~ubuntu0.3.1) ... Selecting previously unselected package slingshot-launcher.

• Can anyone point me to some open source directX rendering engines or frameworks? [on hold]

  - by Jim

  I'm completely new to graphics API programmming, but not at all new to the theory and principle operation of game engines and rendering engines. That being said, I want to do some experiments of rendering very dense geometry scenes in a basic rendering engine or game engine. I don't need a lot of bells and whistles. What I need is enough control that I can implement my own scene graph algorithms and control the rendering pipeline very specifically. My ideal candidate engine would be either a rendering engine or game engine with a modular design that might be ready to go out of the box but would be simple enough in case I need to rip out some of the guts in the rendering management and implement my own. It's a tough call because I'm right at the level where it's almost better to go from scratch, but there's no sense in having to build every single basic thing such as heirarchical transforms, etc. I just want to work with rendering optimization to push dense geometry for maximum FPS. Does anyone have a suggestion for an engine or basic framework to use? I requested DirectX in my title because I figured it would likely be better supported and less likely for me to run into some obscure less-documented problem. But OpenGL might be acceptable if the recommended framework was definitely better than my other options. EDIT: I should add that I really want GPU tessellation support (part of adding to the density of geometry detail).

• Virtualise Excel in a browser

  - by Macros

  Is it possible to give users access to a virtualised instance of Excel - I don't want to give them access to a full OS (although this will clearly be running in the background, all they can access is Excel - they don't even see any other screens)? Secondly, if it is possible, is it possible to do within a browser? Edit I am building a system which is designed to test candidates skills in Excel and for this reason needs to use the full desktop version and not a web app. I don't want to have to ensure Excel is installed on the client machine as there will be issues around differing versions and security as the workbook(s) that are used in the test use VBA extensively to customise and mark the exercises. Ideally my web app would be able to open a session to the server which then just puts the user into an instance of Excel without ever seeing a desktop. I would also need to be able to pass in command line parameters in order to define which workbook to open and also pass in a unique token to identify the user

• Odd behavior of permissions and icons

  - by Urban

  After some virus had infected my Windows 7, I did a complete format and re-installed the OS. I was just installing applications and copying back some data when I noticed some shortcuts changing their icons to something I couldnt recognize (Yellow icons in the image below). Also, a few exe files which previously did not ask for User permission, are now asking for it. Wondering if this is an icon cache problem, I cleared the cache by deleting the IconCache.db in AppData/Local but the problem still persists. Although I did a full system scan with MS Security Essentials, I'm not sure if this is another virus or some other problem. I would appreciate any suggestions you might have. Edit: Now even Firefox needs permissions to launch. It's icon hasnt changed, but it's got the 'shield' overlay on it like the other yellow icons.

• Netbeans automatically changes the file owner when updating files

  - by Alon_A

  We use Netbeans IDE 7.2 to edit our PHP files. In the Run Configuration it is configured as Remote Web Site to automatically save the changes on our web server (Centos OS 6.3). The problem is that every time it is updating the files the owner of the file is changed from apache:apache to userThatUploadedTheFile:users. This causes us problems with SOAP cache files that are configured with apache:apache ownership, and we need to manually chownit back to apache:apache. We've checked the "Preserve Remote File Permissions" checkbox, so the permissions are not changed, only the owner. Is there any solution to preserve the ownership ?

  I have updated to Windows 8 and got Internet Explorer 10, but I don't get the full screen mode, is just like another desktop app. All links on the Windows Store Apps (Bing, News...) redirect to the old desktop and open my default browser (chrome). I have set IE as default browser but that not solve the problem. I have been looking on the IE10 options but I don't see this option. How can I solve this? Maybe this info help: Windows version: Windows 8 Pro 64 bits Installed Browsers: Firefox, Chrome (default), Opera, IE10 I have seem other people with the same version and is working Edit: Is possible to have IE10 by default for windows 8 apps links and Chrome for Desktop?

• Moving files with batch files from one pc to a server, to a another pc - worried about disk corruption

  - by AnchientAnt

  I use scheduled tasks that calls a batch file, that calls more batch files to move about three files from a pc, to a server, then to multiple other pcs. It all happens very quickly, as they are small files. Are there any pitfalls for how fast these transfers happen? I'm just mildly concerned about causing some disk corruption somehow. I use logic like 1. Call MapToPc if files exist then move file to folder on server. Disconnect 2. Call SendtoPCs If files exist (the files just moved to the server) then MapToPCs Move all files Disconnect All of this happens in about 2 secs or less. edit: this on windows 7, server 2003, xp respectively

• GLSL custom interpolation filter

  - by Cyan

  I'm currently building a fragment shader which is using several textures to render the final pixel color. The textures are not really textures, they are in fact "input data" to be used in the formula to generate the final color. The problem I've got is that the texture are getting bi-linear-filtered, and therefore the input data as well. This results in many unwanted side-effects, especially when final rendered texture is "zoomed" compared to original resolution. Removing the side effect is a complex task, and only result in "average" rendering. I was thinking : well, all my problems seems to come from the "default" bi-linear filtering on these input data. I can't move to GL_NEAREST either, since it would create "blocky" rendering. So i guess the better way to proceed is to be fully in charge of the interpolation. For this to work, i would need the input data at their "natural" resolution (so that means 4 samples), and a relative position between the sampled points. Is that possible, and if yes, how ? [EDIT] Since i started this question, i found this internet entry, which seems to (mostly) answer my needs. http://www.gamerendering.com/2008/10/05/bilinear-interpolation/ One aspect of the solution worry me though : the dimensions of the texture must be provided in an argument. It seems there is no way to "find this information transparently". Adding an argument into the rendering pipeline is unwelcomed though, since it's not under my responsibility, and translates into adding complexity for others.

• Which programming language should I choose I want to build this website ...? [closed]

  - by Goma

  Assuming that I will start with just phot sharing website. Every user can add comments to any photo. After that the site will contain news (general news), the admin can add any news and the moderators as well while the users can also add comments on this news. The website will aslo provide photos uploader, so every user will have up to 20 MB ti upload any photos they want. Other users can see these photos or can not depending on the option that the main user chose(if he wants to publish his photos or not). The site should have a small type of forum which provide the ability for admin to ad categories and for user to add topics and replies for each topic in these categoris. These are the things that I can think of now, but the website will add other features as well and services later on. Can you tell me now which programming language can help me to do all that? I need a programming language that provdies the follwing: 1- speed load for pages of the site. 2- easy to add more functions quickly and easy to edit code for any reason. 3- Secure 4- fast in displaying infromation from database.

• Why doesn't my Nvidia driver support 1280*1024?

  - by Alvar

  EDIT: I think the problem is in the NVIDIA x server, that doesn't support an RGB screen from 1990. The screen was the best of them all when it was released. This a strange thing! In windows the EDID must work because 1280*1024 is used as max resolution, but in ubuntu those stuff aren't being received, so how do I tell ubuntu/nivida to find those EDID stuff? Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't. The screens model name is IntelliColor Display/20 and the name of the company is "radius".recived Well, twin view is working but the only maximum resolution is 1024*768. I'm using nividas x server program. If I force it to use 1280*1024 it all crashes and I have to force a reboot. alvar@alvars-laptop:~$ disper -l display DFP-0: HSD121PHW1 resolutions: 320x175, 320x200, 360x200, 320x240, 400x300, 416x312, 512x384, 640x350, 576x432, 640x400, 680x384, 720x400, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 832x624, 1024x768, 1366x768 display CRT-0: CRT-0 resolutions: 320x240, 400x300, 512x384, 680x384, 640x480, 800x600, 1024x768, 1152x864, 1360x768

• What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced)

  - by droidsites

  I've developed a website using PHP but I implemented it on Windows OS and hosted it on Windows server. I just searched the PHP job market to know the on-going technology requirement and to keep my knowledge up-to-date accordingly with the job market. I see more are asking for LAMP stack. I understand the sort of skills required for a developer in PHP and MySQL. But coming to the Linux and Apache what kind of the skills exactly companies expect from a developer? On what should I be focusing in case of Linux, Apache whilst developing my website using these LAMP stack? I am going to develop a new website and want it to be using LAMP. But I want to know what difference it makes? Why LAMP stack got more demand in the job market compared to WAMP ? Edit: Sorry I thought my question is creating confusion ... so I put my question in different words as What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced) Note: I am Linux newbie

• How can I make a non-destructive copy of a (NTFS) partition?

  - by violet313

  I want to recover some deleted files from a healthy NTFS partition on an undamaged hard-disk. In order to leave the partition undisturbed, i plan to use dd to clone the partition to a raw image file & then attempt recovery from that mounted clone. Will dd if=/dev/sd<xn> of=/path/to/output.img perform a non-destructive copy ? Is attempting a restore from a clone using dd the best approach? [edit, wrt Deltiks answer, i need to be a bit clearer about what i'm asking] eg: are there some s/w that can do something more with the original sectors ? eg: if it was a damaged hard-disk i am aware that any kind of read is potentially destructive. but assuming my disk head is not going to suddenly spaz out etc, am i reducing my chances of a successful recovery (at any cost) by using an apparently non-destructive single read of my undamaged hard-disk. (btw: i am planning on using ntfsundelete & testdisk for recovery)

• PC always boots into Command Line

  - by Neptun1337

  My current Problem is, that when I try to install Ubuntu 12.04 Desktop, neither unity nor gnome are installed. During the installation, I am prompted with the message that only the core is installed, and which additional packages I would like to have installed. When I select ubuntu-desktop, the installer grabs some packages and installs them, but after completing the installation and booting into my Ubuntu, i dont get any GUI, but instead I have the command line interface. When I try to start a new Unity session, i get an error saying that Unity is not installed, so I tried to install it. However this changes nothing, my PC still boots into the Command Line. Are there any solutions to my problem? Any help would be greatly appreciated. Thanks in advance. EDIT: I tried to fix it with the following commands: $ sudo apt-get install ubuntu-desktop $ sudo apt-get install gdm $ sudo /etc/init.d/gdm start When I try to boot, I get the Ubuntu splash screen, but then the screen mainly shows white squares, with a few black ones at the top.

• network path not found error on creating schtasks

  - by user50273

  I am getting "ERROR: Network path was not found" when I try to create a scheduled task on my local machine. I am using this command at the command prompt: schtasks /tn taskname /tr taskpath /sc minute /mo 20 /sd 09/23/2010 /s \\%computername% /u username /p password When I give the above command without computername, username and password the task gets created perfectly fine. What am I doing wrong?? EDIT : I got it working by using the below command. I do not understand why it is working becuase I am using /ru and /rp which are remote user and remote password settings whereas I am executing the command on my local machine. And I had to give double quotes to computername. schtasks /tn taskname /tr taskpath /sc minute /mo 20 /sd 09/23/2010 /s "%computername%" /ru username /rp password

• Url for search withing Exchange Server OWA

  - by Martin Vobr

  I can easily create url for searching the Internet for specific term: http://www.bing.com/search?q=example Is is possible to create a similar url for searching my Exchange server mailbox using Outlook Web App? Something like: http://my.exchange.server.tld/owa/search.aspx?q=example EDIT Some of comments asked for target, so here is the clarification: There is a web-based backoffice system which includes customer's email addresses. I want to provide an easy way to show emails related to this customer in a support mailbox. Adding a link to an OWA search result page seemed a way to accomplish quickly. I can lookup emails either via EWS or IMAP. I wanted to reuse OWA for displaying them instead of reinventing the wheel. If creating a search link is not possible what would be best alternative approach? I'm thinking about getting message list via EWS/IMAP, showing them and (at least now) redirecting to OWA in order to display the message content.

• Bay Speaker Panel Installation

  - by JordanD

  I purchased a bay speaker panel that has a molex connector and a sound connector. Do I need to run the sound connector through my tower and somehow out the back into the IO panel? Or is there supposed to be a place on my motherboard for it to connect to? This is a replacement for normal desktop speakers for me to save desk space. Edit: Is there an adapter for the sound cable to the mother board? If so; what is it called? Thanks

• What is the @ sign on the end of file permission on terminal?

  I have a sound file in my app that the iPhone does not play. After checking other problems I checked the file permission in terminal. What I can see is that the file permission of this file has a- @ at the end of it. I don't know if that is the problem but this is the only difference from the other sound files that plays fine. What is this sign ? Could it cause a problem ?

• Linux cannot see Windows 7 partitions on install

  - by Nash0

  I've been trying to install Linux as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Linux installers by boot from CD they see the entire hard drive as unallocated space. I have tried Ubuntu 10.10, Kbuntu 10.10 and Fedora 14 and they all have the same problem. I have also tried the Ubuntu "install in Windows" option and could not get it to work. EDIT: Booting Gparted 0.8.0 from a usb drive did not work. It reported the entire drive as unpartitioned.

• Bad password when logging in via Remote Desktop

  I have just setup a windows 2003 server running in hyper-V. When I log in via Hyper-V it works fine. When I try to login via remote desktop I get a bad user name or password error. I have: Disabled the firewall Enabled remote connections Before I did the above I did not get to the login screen. I can ping the ip address of the image. I am trying to login as Administrator. Anyone have an idea about how to fix this? Edit I have now managed to fix this by changing the password to something without special characters. Strange thing is the I could not see any problems with the passord, had tried typing it into the user name field to check it.

• Audio not working in 12.10

  I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this?

• Hyper V cluster - one VM won't migrate

  - by Chris W

  We have a Failover Cluster built up on 6 blades, each running Hyper V. Each box is running Server 2008 R2. We've got a number of VMs running that all have the same basic config: VHD stored on a cluster shared volume. 2 virtual NICs (1 for LAN connection and 1 for SAN connection). All of our VMs will happily migrate between any other blade apart from one single VM which is running fine on it's current blade but will not migrate to any other location. What could be the cause of it or where should I look to get a detailed error message as I can't seem to find much information logged in any of the logs. Edit: I know the usual culprit is mis-matching resource names. We've already been there with the NICs named differently on some of the blades. As far as we can tell now everything looks to be identical on each bit of metal.

• Lightest way to run Google Hangouts Chrome app on Mac

  - by jadengore

  I recently transitioned to Safari because I'm really tired of how Chrome hogs memory and drains my battery like crazy. The only thing that has been keeping the Chrome icon open is the Hangouts plugin. Basically, I am looking for the lightest way to run Hangouts on my Mac. By light, I mean the least amount of RAM usage, and preferably a way to do it without Chrome open/light version of Chrome that only opens extensions. Any suggestions? EDIT: Another thing I noticed was that Hangouts ignores your default browser if links are sent to you by chat, and when clicked they open in Chrome. My question doesn't relate to this at all, but I found it interesting...

• Is it reasonable to null guard every single dereferenced pointer?

  - by evadeflow

  At a new job, I've been getting flagged in code reviews for code like this: PowerManager::PowerManager(IMsgSender* msgSender) : msgSender_(msgSender) { } void PowerManager::SignalShutdown() { msgSender_->sendMsg("shutdown()"); } I'm told that last method should read: void PowerManager::SignalShutdown() { if (msgSender_) { msgSender_->sendMsg("shutdown()"); } } i.e., I must put a NULL guard around the msgSender_ variable, even though it is a private data member. It's difficult for me to restrain myself from using expletives to describe how I feel about this piece of 'wisdom'. When I ask for an explanation, I get a litany of horror stories about how some junior programmer, some-year, got confused about how a class was supposed to work and accidentally deleted a member he shouldn't have (and set it to NULL afterwards, apparently), and things blew up in the field right after a product release, and we've "learned the hard way, trust us" that it's better to just NULL check everything. To me, this feels like cargo cult programming, plain and simple. A few well-meaning colleagues are earnestly trying to help me 'get it' and see how this will help me write more robust code, but... I can't help feeling like they're the ones who don't get it. Is it reasonable for a coding standard to require that every single pointer dereferenced in a function be checked for NULL first—even private data members? (Note: To give some context, we make a consumer electronics device, not an air traffic control system or some other 'failure-equals-people-die' product.) EDIT: In the above example, the msgSender_ collaborator isn't optional. If it's ever NULL, it indicates a bug. The only reason it is passed into the constructor is so PowerManager can be tested with a mock IMsgSender subclass.
