  • Have there been attempts to make object containers that search for valid programs by auto wiring compatible components?

    - by Aaron Anodide
    I hope this post isn't too "Fringe" - I'm sure someone will just kill it if it is :) Three things made me want to reach out about this now: Decoupling is so in the forefront of design. TDD inspires the idea that it doesn't matter how a program comes to exist as long as it works. Seeing how often the adapter pattern is applied to achieve (1). I'm almost sure this has been tried from a memory of reading about it around the year 2000 or so. If I had to guess, it was maybe about and earlier version of the Java Spring framework. At this time we were not so far from days when the belief was that computer programs could exhibit useful emergent behavior. I think the article said it didn't work, but it didn't say it was impossible. I wonder if since then it has been deemed impossible or simply an illusion due to a false assumption of similarity between a brain and a CPU. I know this illusion existed because I had an internship in 1996 where I programmed neural nets that were supposedly going to exhibit "brain damage". STILL, after all that, I'm sitting around this morning and not able to shake the idea that it should be possible to have a method of programming to allow autonomous components to find each other, attempt to collaborate and their outputs evaluated against a set desired results.

  • Can the "Documents" standard folder be rescued and how?

    - by romkyns
    Anyone who likes their Documents folder to contain only things they place there knows that the standard Documents folder is completely unsuitable for this task. Every program seems to want to put its settings, data, or something equally irrelevant into the Documents folder, despite the fact that there are folders specifically for this job. So that this doesn't sound empty, take my personal "Documents" folder as an example. I don't ever use it, in that I never, under any circumstances, save anything into this folder myself. And yet, it contains 46 folders and 3 files at the top level, for a total of 800 files in 500 folders. That's 190 MB of "documents" I didn't create. Obviously any actual documents would immediately get lost in this mess. My question is: can anything be done to improve the situation sufficiently to make "Documents" useful again, say over the next 5 years? Can programmers be somehow educated en-masse not to use it as a dumping ground? Could the OS start reporting some "fake" location hidden under AppData through the existing APIs, while only allowing Explorer and the various Open/Save dialogs to know where the "real" Documents folder resides? Or are any attempts completely futile or even unnecessary?

  • Loading Entities Dynamically with Entity Framework

    - by Ricardo Peres
    Sometimes we may be faced with the need to load entities dynamically, that is, knowing their Type and the value(s) for the property(ies) representing the primary key. One way to achieve this is by using the following extension methods for ObjectContext (which can be obtained from a DbContext, of course): 1: public static class ObjectContextExtensions 2: { 3: public static Object Load(this ObjectContext ctx, Type type, params Object [] ids) 4: { 5: Object p = null; 6:  7: EntityType ospaceType = ctx.MetadataWorkspace.GetItems<EntityType>(DataSpace.OSpace).SingleOrDefault(x => x.FullName == type.FullName); 8:  9: List<String> idProperties = ospaceType.KeyMembers.Select(k => k.Name).ToList(); 10:  11: List<EntityKeyMember> members = new List<EntityKeyMember>(); 12:  13: EntitySetBase collection = ctx.MetadataWorkspace.GetEntityContainer(ctx.DefaultContainerName, DataSpace.CSpace).BaseEntitySets.Where(x => x.ElementType.FullName == type.FullName).Single(); 14:  15: for (Int32 i = 0; i < ids.Length; ++i) 16: { 17: members.Add(new EntityKeyMember(idProperties[i], ids[i])); 18: } 19:  20: EntityKey key = new EntityKey(String.Concat(ctx.DefaultContainerName, ".", collection.Name), members); 21:  22: if (ctx.TryGetObjectByKey(key, out p) == true) 23: { 24: return (p); 25: } 26:  27: return (p); 28: } 29:  30: public static T Load<T>(this ObjectContext ctx, params Object[] ids) 31: { 32: return ((T)Load(ctx, typeof(T), ids)); 33: } 34: } This will work with both single-property primary keys or with multiple, but you will have to supply each of the corresponding values in the appropriate order. Hope you find this useful!

  • How to cut the line between quality and time?

    - by m3th0dman
    On one hand, I have been taught by various software engineering books ([1] as example) that my job as a programmer is to make the best possible software: great design, flexibility, to be easily maintained etc. One the other hand although I realize that I actually write software for money and not for entertainment, although is very nice to write good code and plan ahead and refactor after writing and ... I wonder if it is always best for the business (after all we should be responsible). Is the business always benefiting from a best code? Maybe I'm over-engineering something, and it's not always useful? So how should I know when to stop in the process to achieving the best possible code? I am sure that experience is something that makes a difference here, but I believe this cannot be the only answer. [1] Uncle Bob's in Clean Code says at page 6 about the fact that: They [managers] may defend the schedule and requirements with passion; but that’s their job. It’s your job to defend the code with equal passion.

  • View the Time & Date in Chrome When Hiding Your Taskbar

    - by Asian Angel
    Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

  • cannot boot Ubuntu after fresh install

    - by Jonathan
    I just installed Ubuntu on a Lenovo v570, and cannot boot into the system. All I get is a loop, where some (bios) info is displayed, and then the computer asks me where I would like to boot from. I tried reinstalling, reinstalling with a custom partition scheme, and boot -repair after the install. None of these work. I can see the files on my harddisk have been copied. I have installed many Ubuntus in the past, as well other distros where custom partitioning is required. I don't know where to find any useful information since I don't even get too the grub menu. One odd thing I noticed. The bios now had options to boot USB, OpenSuse,Fedora, or the HD. I am not dual booting. I also realized that the boot info is for a network boot, which means the computer is not recognizing what to boot. It is boot an HD problem, because I can install other OSs just fine. I am completely stumped. I would like to settle this, and end up with a tutorial, that explains to me what happened.

  • How to customize the initrd embedded in or coming with the kernel image

    - by STATUS_ACCESS_DENIED
    I would like to add some tools and not just kernel modules into the initrd (initramfs-based). Now I'm aware of how to unpack and how to pack the initrd with cpio and have even written a hook for /etc/initramfs-tools/hooks in the past to integrate a third-party kernel module. However, while the available script libraries seem to be geared towards the integration of modules, none of them seems to be for integration of other entities (in particular programs and their dependencies). What options do I have to automate the integration of some useful tools for recovery into the initrd? I'm talking about the "rescue" system that the system drops into if it is unable to mount the root drive given to it by the boot loader. Please note that I don't want the SquashFS approach as is used for Live-CDs because for the issue at hand it will be by far sufficient to include some relatively small tools that aid in recovery of the system (when it gets stuck in initrd and can't boot further). Also, the machines when they run into the issue that we have had in the past tend to boot into the rescue system, but there a few tools are missing to kick the system back on trail ...

  • How do Unity 12.04/Compiz bindings really work?

    - by Daniel
    There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

  • NMap 6.01

    - by TATWORTH
    NMap 6.01 has been released at http://nmap.org/download.html"Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping)."Home page is at http://nmap.org/  Nmap is free to download and use. You can download the source and compile it yourself if you so require.

  • Smarter Search Results in NetBeans IDE 7.2

    - by Geertjan
    After you search your code using NetBeans IDE (using Ctrl-F for "Find" or Ctrl-H for "Replace"), you see the Search Results window, which looks like this: At least, the above is how it looks in NetBeans IDE 7.2. Before that, you didn't have all those extra columns (which can be displayed in the Search Results window after clicking the small button top right in the view) and you also didn't have the quick search (which is invoked by typing directly into the Search Results window), as can be seen here: So, the Search Results window now provides a lot more info than before. Being able to know the path to a file I've found, as well as the last modification date, file size, and the number of matches within the file, is useful at the end of a search process. In the NetBeans IDE 7.2 New & Noteworthy, the above changes are described in the Utilities section, as well as in the Quick Search in OutlineView section, where you can read that these are generic solutions that can be used in your own OutlineViews. Other OutlineViews in NetBeans IDE 7.2, such as the Debugger window, now also have these new features. A related article worth reading is Beefed Up Code Navigation Tools in NetBeans IDE 7.2.

  • digital magazine publishing engine licensing question

    - by nosarious
    I have a publishing engine I have been developing for thirty months but find myself being unable to work on it during my masters degree. I would like to make it open source in the interim to get others to use it and improve how it works. I would like to consider a licensing system that allows for multiple instances of the software for singular users (ie, a newspaper/magazine or zine hosting the code on their own). I would like to limit it from becoming the basis of a larger magazine hosting service right now because it is intended to be an integral part of a much larger publishing ecosystem which allows for the creation, dissemination and collection of publications as a free or very inexpensive service. Right now there is no license associated with it, which is why I am not posting a link here. (This system was developed to counter implied censorship for digital magazines and remove costly and confusing 'barriers to entry' for creators wishing to make interactive digital content. It is intended to be useful for free, but I would like to prevent people taking the code and using it to take advantage of others. It needs a bit of work to separate the content from the page itself to allow the access of multiple which I cannot develop right now) Any help or suggestion on how to handle licensing this code for contributions and use would be appreciated, and if anyone would like to see examples or the github I would be happy to send it.

  • ifconfig can't see USB wireless

    - by Alex
    I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

  • SSD I/O extremely slow installing/booting Ubuntu 12.04

    - by Menda
    These are some useful specs: Macbook Pro 7,1 OWC Mercury Extreme Pro 2,5" SATA SSD (120 GB). Has SandForce driver. Ubuntu 12.04 Desktop 32 bits. One 18 GB partition for GNU/Linux and 1.5 GB for SWAP. MD5 for the Ubuntu install CD is OK. I tried to install Ubuntu. It seems that everything is recognized, but there's a big problem: read and writes to the SSD are extremely slow. For example, the install process, which shouldn't take more than 20 minutes, it takes 7 hours. Then, booting up the computer takes about 20 minutes. I checked and the problem is definitely the SSD. Every access to any file is like 10 times slower than normal. I have tried to format the partition as Ext4 and Ext3 with the same problem. Trying to install other distros like Fedora 17, I have a similar problem. There's a "lag" with the SSD, but not so accused as in Ubuntu. Surprisingly, Debian 6.0 installs and works without any problem. Mac OS works pretty good as well in the other partition, so I discard it's an SSD problem. Thanks for your help!

  • How can I get a user account back?

    - by Ilan
    With all my computers I make one partition for the root and another for /home. This is useful for disasters where I need to reformat the root for ubuntu, but leave my /home data untouched. With the upgrade to 13.10 I had troubles on my wife's computer so I reinstalled 13.10. My own /home files came up, as expected, as if nothing had happened. For my wife, it is a different story - and that is the part where I need help. If I go into Files, computer I can see the home directory. There I can see ilan (my files) and yona (my wife's files). I can open yona, documents and see all her work. This means that all is well and I just need to hook up to her files. So the problem is that I need to create a user called Yona or yona, but something which will get me to exactly the files of interest. I'm not sure if I created her account as standard or an administrator. Is there any way I could tell by looking at the files in /home? I created a new user called Yona as a standard user (hoping that this is the right guess). The account came up as disabled. I pressed on the disabled button so I could change the password. I put in her password but it was refused as too short. Too short, too short, but that is what was used and that is what I need. Can anyone help me before my wife comes home and shoots me? Thanks, Ilan

  • Are Java's public fields just a tragic historical design flaw at this point?

    - by Avi Flax
    It seems to be Java orthodoxy at this point that one should basically never use public fields for object state. (I don't necessarily agree, but that's not relevant to my question.) Given that, would it be right to say that from where we are today, it's clear that Java's public fields were a mistake/flaw of the language design? Or is there a rational argument that they're a useful and important part of the language, even today? Thanks! Update: I know about the more elegant approaches, such as in C#, Python, Groovy, etc. I'm not directly looking for those examples. I'm really just wondering if there's still someone deep in a bunker, muttering about how wonderful public fields really are, and how the masses are all just sheep, etc. Update 2: Clearly static final public fields are the standard way to create public constants. I was referring more to using public fields for object state (even immutable state). I'm thinking that it does seem like a design flaw that one should use public fields for constants, but not for state… a language's rules should be enforced naturally, by syntax, not by guidelines.

  • Single-developer GIT workflow (moving from straightforward FTP)

    - by melat0nin
    I'm trying to decide whether moving to VCS is sensible for me. I am a single web developer in a small organisation (5 people). I'm thinking of VCS (Git) for these reasons: version control, offsite backup, centralised code repository (can access from home). At the moment I work on a live server generally. I FTP in, make my edits and save them, then reupload and refresh. The edits are usually to theme/plugin files for CMSes (e.g. concrete5 or Wordpress). This works well but provides no backup and no version control. I'm wondering how best to integrate VCS into this procedure. I would envisage setting up a Git server on the company's web server, but I'm not clear how to push changes out to client accounts (usually VPSes on the same server) - at the moment I simply log into SFTP with their details and make the changes directly. I'm also not sure what would sensibly represent a repository - would each client's website get their own one? Any insights or experience would be really helpful. I don't think I need the full power of Git by any means, but basic version control and de facto cloud access would be really useful.

  • Project Jigsaw: On the next train

    - by Mark Reinhold
    I recently proposed to defer Project Jigsaw from Java 8 to Java 9. Feedback on the proposal was about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. The ultimate decision rested, of course, with the Java SE 8 (JSR 337) Expert Group. After due consideration, a strong majority of the EG agreed to my proposal. In light of this decision we can still make progress in Java 8 toward the convergence of the higher-end Java ME Platforms with Java SE. I previously suggested that we consider defining a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. JEP 161 lays out a specific initial proposal for such Profiles. There is also much useful work to be done in Java 8 toward the fully-modular platform in Java 9. Alan Bateman has submitted JEP 162, which proposes some changes in Java 8 to smooth the eventual transition to modules, to provide new tools to help developers prepare for modularity, and to deprecate and then, in Java 9, actually remove certain API elements that are a significant impediment to modularization. Thanks to everyone who responded to the proposal with comments and questions. As I wrote initially, deferring Jigsaw to a Java 9 release in 2015 is by no means a pleasant decision. It does, however, still appear to be the best available option, and it is now the plan of record.

  • XSLT and possible alternatives [on hold]

    - by wirrbel
    I had a look at XSLT for transforming one XML file into another one (HTML, etc.). Now while I see that there are benefits to XSLT (being a standardized and used tool) I am reluctant for a couple of reasons XSLT processors seem to be quite huge / resource hungry XML is a bad notation for programming and thats what XSLT is all about. It do not want to troll XSLT here though I just want to point out what I dislike about it to give you an idea of what I would expect from an alternative. Having some Lisp background I wonder whether there are better ways for tree-structure transformations based upon some lisp. I have seen references to DSSSL, sadly most links about DSSSL are dead so its already challenging to see some code that illustrates it. Is DSSSL still in use? I remember that I had installed openjade once when checking out docbook stuff. Jeff Atwood's blog post seems to hint upon using Ruby instead of XSLT. Are there any sane ways to do XML transformations similar to XSLT in a non-xml programming language? I would be open for input on Useful libraries for scripting languages that facilitate XML transformations especially (but not exclusively) lisp-like transformation languages, or Ruby, etc. A few things I found so far: A couple of places on the web have pointed out Linq as a possible alternative. Quite generally I any kind of classifications, also from those who have had the best XSLT experience. For scheme http://cs.brown.edu/~sk/Publications/Papers/Published/kk-sxslt/ and http://www.okmij.org/ftp/Scheme/xml.html

  • Init.d script gets return code 1 when calling itself, how can I get output?

    - by Per
    My question is, how can I modify the script so that it will tell me what goes wrong? The scenario is this: I'm trying to get Sonatype Nexus to start as a service in Ubuntu 10.04, and it just will not work. (I'm not looking for help on how to run Nexus, but on how to get some useful output from a script) It works when invoking it with sudo /etc/init.d/nexus start but fails when using sudo service nexus start I have run the update-rc.d command on it, and done everything according to instructions. The nexus init.d-script has a point where it calls itself when it detects that it should run as another user ('nexus'): su -m $RUN_AS_USER -c "\"$REALPATH\" $2" which expands to su -m nexus -c '"/opt/nexus-2.0.2/bin/jsw/linux-x86-64/nexus" start' when adding the -x debug flag to the script. This command results in return code 1. It never executes - I've set -x debug flag on the script, placed echo commands with redirect to file at the start of script to trace, etc. I cannot get any output telling me why the command will not execute. I've tried appending redirect to file after the above script line, inside the quotes, outside, any way I could imagine. All info I can get is by inserting a line echo $? after the su line, which outputs '1'. Is there a way I can see what happens when the su command runs?

  • AdSense (reports) and custom channels

    - by RobbertT
    Please help me to further understand custom channels. As Google says it is a way to map your ads, but I still have a few questions: Is it correct that a single custom channel per 1 ad is not very useful, since you can specify Ad blocks in the AdSense reports? I have multiple Ads in multiple custom channels. After this I created 1 custom channel and added all the ads to it. I made this channel targetable, so people can target through this channel on all ads at once. Is this a good way to do it? In other words, is it possible to have ads in multiple custom channels (without targeting, just for analyzing) and then create 1 custom channel with targeting that embraces all the (desired) ads? Why is it not possible for me to analyze custom channels (or ad blocks & formats) per site in the Adsense (reports). Or am I doing something wrong? If not, I have to create different custom channels per site to see how certain ads are doing on a site level?

  • Engineered Systems and PCI

    - by Joel Weise
    Oracle has a number of different engineered systems.  These are design to be highly integrated, optimized and secure systems.  The Exadata database engineered system and the Exalogic application engineered system are two good examples.  Often I am asked how these comply with different standards and regulations.  Exalogic is the Oracle engineered system that supports applications and the focus of today's blog.  First, we must recognize that as a collection of hardware and software, we cannot simply state that Exalogic is "compliant" with PCI DSS.  This is because Exalogic must be implemented within the context of one's existing IT infrastructure, the security features of that infrastructure, the governance framework that exists, security policies, operational procedures, and other factors.  What we can say though, is that Exalogic has been designed with various security capabilities that can be utilized to support compliance to PCI DSS as well as other standards and regulations (e.g., NIST and HIPAA).  Given that, Exalogic can be an excellant platform for running PCI related payment applications.  Coalfire Systems, a leading QSA in the US, has evaluated Exalogic against PCI DSS and supports this position.  Their evaluation can be found here: Exalogic and PCI Compliance. I hope you find it useful

  • A few questions about how JavaScript works

    - by KayoticSully
    I originally posted on Stack Overflow and was told I might get some better answers here. I have been looking deeply into JavaScript lately to fully understand the language and have a few nagging questions that I can not seem to find answers to (Specifically dealing with Object Oriented programming. I know JavaScript is meant to be used in an OOP manner I just want to understand it for the sake of completeness). Assuming the following code: function TestObject() { this.fA = function() { // do stuff } this.fB = testB; function testB() { // do stuff } } TestObject.prototype = { fC : function { // do stuff } } What is the difference between functions fA and fB? Do they behave exactly the same in scope and potential ability? Is it just convention or is one way technically better or proper? If there is only ever going to be one instance of an object at any given time, would adding a function to the prototype such as fC even be worthwhile? Is there any benefit to doing so? Is the prototype only really useful when dealing with many instances of an object or inheritance? And what is technically the "proper" way to add methods to the prototype the way I have above or calling TestObject.prototype.functionName = function(){} every time? I am looking to keep my JavaScript code as clean and readable as possible but am also very interested in what the proper conventions for Objects are in the language. I come from a Java and PHP background and am trying to not make any assumptions about how JavaScript works since I know it is very different being prototype based. Also are there any definitive JavaScript style guides or documentation about how JavaScript operates at a low level? Thanks!

  • Mobile development, recommended computer configuration?

    - by MikaelW
    Hi, For the last 4 weeks, I have been trying to get into mobile development. Done a couple of tutorials, read some books, developed a couple of dummy Android apps. The thing is my computer is a 5 years old laptop, it is slow and time has come to replace it and I’m looking at different offers online. Have you got any recommendations? Is there any must-have that should make my developer life easier in the future? Is there anything specific that may be useful at a more advanced stage of development that I just can’t think of right now on the hardware side? (I mean apart from good proc, lots of RAM, many USB ports...) One thing I can think of is to have three OS on the same workstation: Windows, Unix and MacOS (so far I focused on android/java/eclipse but am interested in Iphone/objC/xcode as well) but that’s more on the software side. Anyway, would be grateful for any recommendations. Thanks in advance! Mikael PS: I’m quite free on the budget side of things PPS: I'm aware it's not really a programming question but will still be of interest to some programmers here.

  • Do you have to recreate workspaces after upgrading a TFS 2008 server to TFS 2010?

    I am just reposting this thread from a MSDN forum since it seems to be unavailable. It was very useful when I was having trouble with my folder mappings after migrating to TFS 2010. Question: I opened VS2008 and connected it to the upgraded 2010 TFS server.  Upon clicking any of our Team Projects in source control explorer I get "Team Foundation Error - The workspace MYWORKSPACE;DOMAIN\MYUsername already exists on computer MYPCNAME." Answer: The same local paths on your machine are mapped to 2 different workspaces, one on the preupgrade server and one on the postupgrade server.  It's not safe to have multiple workspaces on different servers mapped to the same local paths b/c you could pend some changes while connected to one server, and the other server would have no idea what you did.  You should either delete your conflicting workspaces from one of the servers (if you don't need them on both), or test the new TFS instance from a new workspace (on different machine). If you want to test an existing production workspace on both servers, then yes, you will have to mess around with the workspace cache. You don’t have to delete the entire cache, you just need to run "tf workspaces /remove:* /server:<serverurl>" to clear the cached workspaces from a server (the command won't delete the workspaces), and possibly "tf workspaces /server:<server>" to refresh the workspace cache for a given server.  You will also have to do back up and restore the workspace before switching servers or your local files could be inconsistent.

  • Understanding interfaces [closed]

    Possible Duplicate: When to use abstract classes instead of interfaces and extension methods in C#? Why are interfaces useful? What is the point of an interface? What other reasons are there to write interfaces rather than abstract classes? What is the point of having every service class have an interface? Is it bad habit not using interfaces? I am reading Microsoft Visual C# 2010 Step by Step which I feel it is a very good book on introducing you to the C# language. I have just finished reading a chapter on interfaces and although I understood the syntax of creating and using interfaces I have trouble of understanding the point on why should I use them? Correct me If I am wrong but in an interface you can only declare methods names and parameters.The body of the method should be declared in the class that inherits the interface. So in this case why should I declare an interface if I am going to declare the entire method in the class that inherits that interface? What is the point? Does this have something to do with the fact that a class can inherit multiple interfaces?
