• deep expertise in one technology or not so deep understanding of many technologies

  - by district

  Hello everyone. I started to feel a little bit confused recently about my career path as software developer, about what I do, what I know and do I need it. I am 21 years now and I have 3 years of experience. I've been dealing with java/C++ projects, Servlet/JSP/JSF, desktop QT, also some mobile development (Symbian, Android) I work for a quite a small company, around 20 developers with different projects. I'm also a student. The problem is that I'm not sure if I'm taking the right road here. I'm starting to work with new technology every few months. I don't have deep understanding in any of these and I'm not sure if this is what I need. I will probably not become an expert in any of these. The other path is maybe to start working for a big company which use one set of technologies and become an expert. What's your opinion on this topic ? What is more valuable ?

• When browsing a specific network share remotely, Windows Explorer continuously jumps back to the parent folder

  - by Evil Pigeon

  I am accessing a specific network path on another domain. It looks something like this: \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\Website\ In under 30 seconds, I am automatically jumped back to \\CoputerName.OtherDomain.in\c$\Inetpub\Testing\ In less time it then jumps back to \\CoputerName.OtherDomain.in\c$\Inetpub\ Then it jumps back to c$ for its final resting place. \\CoputerName.OtherDomain.in\c$\ At first I thought this had to with a faulty keyboard, but this behaviour also occurs when the window does not have focus. It's as if windows thinks that the folder no longer exists (as in someone else has deleted or moved it). This behaviour is not specific to my PC either, it occurs from other machines in the office. Edit: It looks like this issue only occurs from other Windows 7 machines. There are no issues accessing the path from XP.

• Error instantiating Texture2D in MonoGame for Windows 8 Metro Apps

  - by JimmyBoh

  I have an game which builds for WindowsGL and Windows8. The WindowsGL works fine, but the Windows8 build throws an error when trying to instantiate a new Texture2D.

• Scalable Architecture for modern Web Development [on hold]

  - by Jhilke Dai

  I am doing research about Scalable architecture for Web Development, the research is solely to support Modern Web Development with flexible architecture which can scale up/down according to the needs without losing any core functionality. By Modern Web I mean to support all the Devices used to access websites, but the loading mechanism for all devices would be different. My quest of architecture is: For PC: Accessing web in PC is faster but it also depends on the Geo-location, so, the application would check by default the capacity of Internet/Browser and load the page according to it. For Mobile: Most of the mobile design these days either hide information or use different version of same application. eg: facebook uses m.facebook.com which is completely different than PC version. Hiding the things from Mobile using JavaScript or CSS is not a solution as it'll consume the bandwidth and make the application slow. So, my architecture research is about Serving one Application, which has different stack. When the application receives the request it'd send the Packaged Stack to the received request. This way the load time for end users would be faster and maintenance of application for developers would be easier. I am researching about for 4-tier(layered) architecture like: Presentation Layer Application Logic Layer -- The main Logic layer which stores the Presentation Stack Business Logic Layer Data Layer Main Question: Have you come across of similar architecture? If so, then can you list the links here, I'm very much interested to learn about those implementations specially in real world scenario. Have you thought about similar architectures and tried your own ideas, or if you have any ideas regarding this, then I urge to share. I am open to any discussions regarding this, so, please feel free to comment/answer.

• ApplicationPool in IIS 7.5 crashes with identifty set to NetworkService

  - by Ravi

  We have a web application running on IIS 7.5 with the identity of the Custom Application Pool set to NetworkService. This was working fine for some days and now the application pool has gone in to a stopped state. The following error message is displayed in the Event Viewer Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bcd2b Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b29c Exception code: 0xc0000005 Fault offset: 0x00038c19 Faulting process id: 0xa28 Faulting application start time: 0x01cbb2e5707aa2b2 Faulting application path: C:\Windows\SysWOW64\inetsrv\w3wp.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll Report Id: ae3f0610-1ed8-11e0-abf8-000c297f918f We are able to start the application pool only after changing the identity to LocalSystem. Why does the application pool fails to run with identity set to NetworkService. Can any one help us resolving this issue?

• Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative hand

  - by Karolis T.

  Can't solve this one, here's my .htaccess: AuthPAM_Enabled Off AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthName "MESSAGE" Require ldap-group cn=CHANGED, cn=CHANGED AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)" AuthLDAPBindDN CHANGED AuthLDAPBindPassword CHANGED AuthLDAPGroupAttribute memberUid AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..). Apache version: Apache/2.2.9 (Debian) The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem. EDIT: LDAP modules are loaded, the problem is not with them being missing. # ls /etc/apache2/mods-enabled/*ldap* /etc/apache2/mods-enabled/authnz_ldap.load /etc/apache2/mods-enabled/ldap.load EDIT2: Solved it by changing funky Require ldap-group cn=CHANGED, cn=CHANGED line with Require valid-user Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP. (right? :/)

• Subversion multi checkout post-commit hook?

  - by FLX

  The title must sound strange but I'm trying to achieve the following: SVN repo location: /home/flx/svn/flxdev SVN repo "flxdev" structure: + Project1 ++ files + Project2 + Project3 + Project4 I'm trying to set up a post-commit hook that automatically checks out on the other end when I do a commit. The post-commit doc explicitly lists the following: # POST-COMMIT HOOK # # The post-commit hook is invoked after a commit. Subversion runs # this hook by invoking a program (script, executable, binary, etc.) # named 'post-commit' (for which this file is a template) with the # following ordered arguments: # # [1] REPOS-PATH (the path to this repository) # [2] REV (the number of the revision just committed) So I made the following command to test: REPOS="$1" REV="$2" echo "Updated project $REPOS to $REV" However when I edit files in Project1 for example, this outputs "Updated project /home/flx/svn/flxdev to 1016" I'd like this to be: "Updated project Project1 to 1016" Having this variable allows me to specify to do different actions per project post-commit. How can I specify the project parameter? Thanks! Dennis

• Mac internet problems

  - by Bradley Herman

  Our office is set up with mostly macs (7 of them) but we do have a windows laptop and a windows desktop on the network as well. The network is configured with a modem going into a switch/router throughout the office to the computers, along with a wireless router. Everything runs fine most of the time, but periodically while using the web, certain sites will stop loading and timeout repeatedly. This usually lasts 20 minutes or so and can be incredibly annoying. Resetting the modem/router and/or rebooting the computer never helps. The weirdest part is that in almost every case, the websites are fine on our Windows machines. I frequently use github, google, Stack Overflow, and jQuery reference and I can count on the sites being unavailable to me at least once a day. While I can't get them to load, I can spin my chair around to the windows server behind me and load the sites just fine. Any idea what the hell could be going on here?

• Setting XSL-FO XML Schema in Visual Studio

  - by Lukasz Kurylo

  I'm playing lately with an XSL-FO for generating a pdf documents. XSL-FO has a long list of available tags and attributes, which for a new guy who want to create a simple document is a nightmare to find a proper one. Fortunatelly we can set an schema for XSL-FO, so will result in acquire a full intellisense in VS. For a simple *.fo file, we can set the path to the schema directly in file: <?xml version="1.0" encoding="utf-8"?> <fo:root       xmlns:fo="http://www.w3.org/1999/XSL/Format"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation=" http://www.w3.org/1999/XSL/Format http://www.xmlblueprint.com/documents/fop.xsd"> ...   We can of course use the build in VS XML Schemas selector. To use it, we must copy the schema file to the Schemas catalog (defaut path for VS2012 is C:\Program Files (x86)\Microsoft Visual Studio 11.0\Xml\Schemas). Then we can go to Properties of the opened xml/xslt file and set the new added schema to file:                 From now, we should have an enable intellisense as shown below: .

• Windows 2003 GPO Software Restrictions

  - by joeqwerty

  We're running a Terminal Server farm in a Windows 2003 Domain, and I found a problem with the Software Restrictions GPO settings that are being applied to our TS servers. Here are the details of our configuration and the problem: All of our servers (Domain Controllers and Terminal Servers) are running Windows Server 2003 SP2 and both the domain and forest are at Windows 2003 level. Our TS servers are in an OU where we have specific GPO's linked and have inheritance blocked, so only the TS specific GPO's are applied to these TS servers. Our users are all remote and do not have workstations joined to our domain, so we don't use loopback policy processing. We take a "whitelist" approach to allowing users to run applications, so only applications that we approve and add as path or hash rules are able to run. We have the Security Level in Software Restrictions set to Disallowed and Enforcement is set to "All software files except libraries". What I've found is that if I give a user a shortcut to an application, they're able to launch the application even if it's not in the Additional Rules list of "whitelisted" applications. If I give a user a copy of the main executable for the application and they attempt to launch it, they get the expected "this program has been restricted..." message. It appears that the Software Restrictions are indeed working, except for when the user launches an application using a shortcut as opposed to launching the application from the main executable itself, which seems to contradict the purpose of using Software Restrictions. My questions are: Has anyone else seen this behavior? Can anyone else reproduce this behavior? Am I missing something in my understanding of Software Restrictions? Is it likely that I have something misconfigured in Software Restrictions? EDIT To clarify the problem a little bit: No higher level GPO's are being enforced. Running gpresults shows that in fact, only the TS level GPO's are being applied and I can indeed see my Software Restictions being applied. No path wildcards are in use. I'm testing with an application that is at "C:\Program Files\Application\executable.exe" and the application executable is not in any path or hash rule. If the user launches the main application executable directly from the application's folder, the Software Restrictions are enforced. If I give the user a shortcut that points to the application executable at "C:\Program Files\Application\executable.exe" then they are able to launch the program. EDIT Also, LNK files are listed in the Designated File Types, so they should be treated as executable, which should mean that they are bound by the same Software Restrictions settings and rules.

• What types of programming contest problems are there?

  - by Alex

  Basically, I want to make a great reference for use with programming contests that would have all of the algorithms that I can put together that I would need during a contest as well as sample useage for the code. I'm planning on making this into a sort of book that I could print off and take with me to competitions. I would like to do this rather than simply bringing other books (such as Algorithms books) because I think that I will learn a lot more by going over all of the algorithms myself as well as I would know exactly what I have in the book, making it more efficient to have and use. So, I've been doing research to determine what types of programming problems and algorithms are common on contests, and the only thing I can really find is this (which I have seen referenced a few times): Hal Burch conducted an analysis over spring break of 1999 and made an amazing discovery: there are only 16 types of programming contest problems! Furthermore, the top several comprise almost 80% of the problems seen at the IOI. Here they are: Dynamic Programming Greedy Complete Search Flood Fill Shortest Path Recursive Search Techniques Minimum Spanning Tree Knapsack Computational Geometry Network Flow Eulerian Path Two-Dimensional Convex Hull BigNums Heuristic Search Approximate Search Ad Hoc Problems The most challenging problems are Combination Problems which involve a loop (combinations, subsets, etc.) around one of the above algorithms - or even a loop of one algorithm with another inside it. These seem extraordinarily tricky to get right, even though conceptually they are ``obvious''. Now that's good and all, but that study was conducted in 1999, which was 13 years ago! One thing I know is that there are no BigNums problems any more (as Java has a BigInteger class, they have stopped making those problems). So, I'm wondering if anyone knows of any more recent studies of the types of problems that may be seen in a programming contest? Or what the most helpful algorithms on contests would be?

• compiling php5.4 on macosx 10.6.8

  - by ling

  I'm trying to compile php 5.4.7 on mac osx 10.6.8. I could install it using the default procedure: ./configure \ --prefix=/usr/local \ --with-config-file-path=/usr/local/etc \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-mysql sudo make clean sudo make sudo make install But now if I try to install to compile php with the curl module it fails: ./configure \ --prefix=/usr/local \ --with-config-file-path=/usr/local/etc \ --with-curl=/usr \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-mysql sudo make clean sudo make = last lines of make output: Undefined symbols: "_CRYPTO_set_locking_callback", referenced from: _zm_shutdown_curl in interface.o _zm_startup_curl in interface.o "_CRYPTO_num_locks", referenced from: _zm_shutdown_curl in interface.o _zm_startup_curl in interface.o "_CRYPTO_get_id_callback", referenced from: _zm_startup_curl in interface.o "_CRYPTO_set_id_callback", referenced from: _zm_shutdown_curl in interface.o _zm_startup_curl in interface.o ld: symbol(s) not found collect2: ld returned 1 exit status make: * [libs/libphp5.bundle] Error 1 I read somewhere ( http://user.xmission.com/~georgeps/documentation/tutorials/compilation_and_makefiles.html ) that in this case, I should tell the compiler where to find the missing library, so that it can links the missing files. The problem is that I don't what library I should look for, is it libssl2 ?

• Java Applet or Unity3D for Cross-Platform 3D Surveying App

  - by Jake M

  Do you think a Java Applet or Unity3D Application is the best option to make a cross-browser 3d web-app? I intend to make a web application that displays 3d environments that can be navigated by dragging(with a finger or mouse depending on the platform). The web app will render 3d environments of development sites including contours, water pipeline locations, buildings etc. The application must work on Windows Desktop, Android, iOS and Windows Phone. So this is why I am tending towards a web-app as opposed to cross-platform smart phone library(like Mosync or Marmalade). The 3d environments will be navigable(by dragging around) and contain simple(not detailed) 3d objects like buildings, mountains, pipelines, etc. One thing I know is that WebGL is out because it doesn't work on IE and has limited support on Smart Phones(am I correct to completely disregard WebGL?). Will future Smart Phone browsers continue to support Java Applets? Also is it really true I can write ONE Application/Game in Unity3D and simply compile it to run on Windows Windows, Mac, Xbox 360, PlayStation 3, Wii, iPad, iPhone and Android? Would you suggest the Unity3D application path or the Unity3D Web Player path? Concerning Unity3D, there's one thing I am unsure about: do all Unity3D features work on iOS and Android?

• Alienware M17x R3: Possible downclock

  - by Ywen

  I installed recently Kubuntu 11.10 32 bits (had graphics driver issues, wanted to try on 32 bits version) on my new Alienware M17x, with a Core i7-2670QM CPU. Cores are supposed to be clocked at 2.2 GHz, however the output of $ cat /proc/cpuinfo | grep -i "hz" gives me: model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 If useful, the AC adapter is plugged in (yet the ouput is the same when the computer is powered only by the battery) and I have Firefox and Eclipse running. Does /proc/cpuinfo reflect a possible automatic downclock made to save power if processor load is low or is this output abnormal? EDIT: Ok, I checked and yes, the ouput does vary in function of the load. I reach 2.2 GHz when needed. But my following problem remains. I was checking my CPU clocking because I experienced poor performances when reading 720p video files on Ubuntu with VLC or mplayer when on battery (and I believe VLC by default only uses CPU, not GPU to decode), whereas I haven't got such problems with VLC on Windows (which made me think it wasn't coming from a BIOS option, plus every option in the BIOS regarding the CPU is turned ON).

• How do you create a bootable partition on a USB drive?

  - by Nathan DeWitt

  I have a bootable ISO designed to be burned to a double-layer DVD. I don't have a double layer DVD burner, so I would like to stick the ISO image on a 50 GB partition on a USB hard drive I have. How do I get the boot info onto the hard drive? If it helps, it's an OSx86 Live CD. Attempt 1: booted into Ubuntu 9.04 LiveCD deleted the partition on my existing USB hard drive sudo dd if=/path/to/image.iso of=/dev/MyUSB booted to USB drive error: Error Loading OS Atempt 2: booted into Ubuntu 9.04 LiveCD deleted the partition on my existing USB hard drive sudo mkdosfs -I -v -n iPC /dev/MyUSB sudo syslinux /dev/MyUSB sudo dd if=/path/to/image.iso of=/dev/MyUSB booted to USB drive error: Selected boot device not available - strike F1 to retry boot, F2 for setup utility

• Vertex fog producing black artifacts

  - by Nick

  I originally posted this question on the XNA forums but got no replies, so maybe someone here can help: I am rendering a textured model using the XNA BasicEffect. When I enable fog, the model outline is still visible as many small black dots when it should be "in the fog". Why is this happening? Here's what it looks like for me -- http://tinypic.com/r/fnh440/6 Here is a minimal example showing my problem: (the ship model that this example uses is from the chase camera sample on this site -- http://xbox.create.msdn.com/en-US/education/catalog/sample/chasecamera -- in case anyone wants to try it out ;)) public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Model model; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); // TODO: use this.Content to load your game content here model = Content.Load<Model>("ship"); foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect be in mesh.Effects) { be.EnableDefaultLighting(); be.FogEnabled = true; be.FogColor = Color.CornflowerBlue.ToVector3(); be.FogStart = 10; be.FogEnd = 30; } } } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here model.Draw(Matrix.Identity * Matrix.CreateScale(0.01f) * Matrix.CreateRotationY(3 * MathHelper.PiOver4), Matrix.CreateLookAt(new Vector3(0, 0, 30), Vector3.Zero, Vector3.Up), Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, 16f/9f, 1, 100)); base.Draw(gameTime); } }

• How to install Ubuntu 13.10 on Hybrid Disk alongside Windows 8.1

  - by user205691

  I am having trouble installing Ubuntu 13.10 on HP Envy 4-1046tx ultrabook. When i bought this, it came with windows 7 pre-installed, but i upgraded it to 8 and now recently to 8.1. But somehow, i feel 8.1 is slower or something went wrong with the upgrade and made my system slow. I want to try Dual booting Ubuntu 13.10 with windows 8.1 The system recovery drive has windows 7 recovery files. SSD has 4GB allocated to windows 8 (i think for hibernation/rapid start). 25GB of SSD is free and i want to install ubuntu on this SSD pointing it to "/" I will also shrink the windows partition (the only other partition available apart from recovery & SSD) to free up 100GB and allocate this space to "/home" during ubuntu installation. I tried the above steps while on windows 8, but not successful. Ubuntu installation went fine, but the grub was not loaded. I tried to deploy linux via EasyBCD, but after that also, selecting linux in the boot would load grub on command prompt and do nothing. While ubuntu installation, i also deleted the raid drivers with sudo dmraid -rE, but still ubuntu didnt recognize my windows. I think i am missing some steps, so this time i want to do it right with proper info before starting the process. My requirements: dual boot Ubuntu with windows 8.1 c:\ shrinked windows with 300GB on sda1, 100GB for /home on sda1 & ubuntu installed on 25GB SSD volume sda2 (this is mSata i think) GRUB or EFI that helps me load both OS properly without breaking anything SWAP partition can be added if needed on sda1 (4gb?)? I have backed up my drive and have a 16GB usb3.0 with ubuntu loaded. I hope i have mentioned everything i need and know.. All i need now is some guidance and what to do right so that this installation goes as planned :)

• Semantic Versioning and splitting apart a library, providing a bundled build

  - by Derick Bailey

  I've got a nice, fairly popular JavaScript library that is following Semantic Versioning. The current library has a few dependency libraries, which are available either as separate downloads or as part of a single bundled download. I see a need to head down this path further. I want to extract additional, smaller libraries out of the one larger library. Each of these extracted libraries would be available as separate files, or inside of the one bundled build, again. If I go down this path of extracting the libraries, and providing a bundled version of the final code, does this require a full version change in semantic versioning? Would I have to bump from 1.x to 2.x? My first thought it no: I will not change any public API, so I don't have to change the major version number. But then I wonder... well, I am restructuring a lot of things, even though the final API for the bundled version would be the same. Is there a clear answer from semver on something like this? Do I need to bump first, second or third dot? Or something else?
