  • Time Machine for Windows?

    - by Blub
    Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

  • How to deploy ClickOnce .Net 3.5 application on 3.0 machine

    - by Buthrakaur
    I have .Net 3.5 SP1 WPF application which I'm successfully deploying to client computers using ClickOnce. Now I got new requirement - one of our clients need to run the application on machines equipped just with .Net 3.0 and it's entirely impossible to upgrade or install anything on the machines. I already tried to run the 3.5 application with some of the 3.5FW DLLs copied to the application directory and it worked without any problems. The only problem at the moment is ClickOnce. I already made it to include the 3.5FW System.*.dll files in list of application files, but it always aborts installation on 3.0 machine with this error message: Unable to install or run the application. The application requires that assembly System.Core Version 3.5.0.0 be installed in the Global Assembly Cache (GAC) first. Please contact your system administrator. I already tried to tweak prerequisites on Publish tab of my project, but no combination solved the issue. What part of ClickOnce is responsible for checking prerequisites? I already tried to deploy using mageui.exe, but the 3.5FW error is still present. What should I do to fore ClickOnce to stop checking any prerequisites at all? The project is created using VS2010.

  • Problems with ASP.NET, machine-level web.config, and the location element

    - by Daniel Schaffer
    I've got a server running Windows Web Server 2008 R2. The machine-level web.config has the following entries: <location path="Preview"> <appSettings> <add key="Environment" value="Preview" /> </appSettings> </location> <location path="Staging"> <appSettings> <add key="Environment" value="Staging" /> </appSettings> </location> <location path="Production"> <appSettings> <add key="Environment" value="Production" /> </appSettings> </location> I have a website that I'd set up in the direction D:\Sites\Preview\, so the full path would be D:\Sites\Preview\WebSite1. If I put a simple aspx file that just outputs the value of ConfigurationManager.AppSettings["Environment"], it displays the value Preview. I'm not clear on exactly how that works, but it does. I'd set this up several weeks ago, and just now tried to duplicate this - I put a second site in the D:\Sites\Preview\ directory, expecting that it would automatically pick up the appropriate appSettings entries, but for some reason it hasn't - the same aspx page doesn't show anything. Additionally, when I go into the IIS manager and open the Configuration Editor, there are no settings in there, whereas there are settings listed for the first site. Any ideas as to what I could be missing? Is the location element intended to work like this, or did I just find some magical fluke with my first site?

  • JFLAP Turing Machine shortcut problem

    - by Robert Lamb
    In JFLAP (http://jflap.org), there are some shortcuts for Turing machine transitions. One of these shortcuts allows you to transition as long as the current tape symbol isn't the indicated symbol. For example, the transition !g,x;R basically says "Take this transition if the current tape symbol is not g". So far, so good. But the transition I want is !?,~;R which basically says "Move right as long as the current symbol is not the end-of-string (empty cell) symbol". The problem is I cannot figure out how to type in "!?". The JFLAP online documentation (http://www.jflap.org/tutorial/turing/one/index.html#syntax) has this to say: The first shortcut is that there exists the option of using the “!” character to convey the meaning of “any character but this character.” For example, concerning the transition (!a; x, R), if the head encounters any character but an “a”, it will replace the character with an “x” and move right. To write the expression “!?”, just type a “1” in when inputting a command. My question is...how do I actually do what that last sentence is trying to explain to me? Thanks for your help! Robert

  • Can TFS workspaces be used without being tied to a specific machine?

    - by GWLlosa
    So I've got a situation where we have a project with 10 developers. Each developer, when they come in for the day, is randomly issued a machine to use for development that day. The machine names are different, say DEV01 - DEV10. At the time that they are issued to the developers, the machines are identical, and no changes the developers make during the day are persisted on the machines (source code changes are stored in TFS, not locally). These are of course actually virtual machines, but that's not really relevant to the point at hand. The problem is that each morning, the developers run into 3 issues: 1) The machine that they are assigned may not be the same machine they were last assigned to. For example, DevMan A might have used DEV04 yesterday, and received DEV06 today. His workspace definitions are now tied to DEV06; he must create a new workspace, or migrate the old workspace to DEV04. 2) The machine that they are assigned may have been in use yesterday, and some of the mappings may conflict. For example, DevMan A might have DEV04 today, and wish to create a workspace mapping the project folder to "C:\MyProj\Solution". However, DevMan B had DEV04 yesterday, and he used the same project folder. TFS now complains. 3) This may be the first time they are on a given machine. They now need to recreate for this machine all of their source-control mappings for the new machine. All of these issues can be resolved in a straightforward fashion on a case-by-case basis, but it does sap some productivity from the morning. We'd much prefer if the TFS workspace definitions could be 'relaxed', such that they did not include the machine name in the definition somehow. Barring that, if anyone is aware of a solution to the above problems that can run automatically, or with limited user intervention, that would also be ideal.

  • Passing HTML form data in the URL on local machine (file://)

    - by atzz
    Hi, I'm building a small HTML/JS application for primary use on local machine (i.e. everything is accessed via file:// protocol, though maybe in the future it will be hosted on a server within intranet). I'm trying to make a form with method="get" and action="target.html", in the hope that the browser will put form data in the URL (like, file://<path>/target.html?param1=aaa&param2=bbb). However, it's not happening (target.html opens fine, but no parameters is passed). What am I doing wrong? Is it possible to use forms over file:// at all? I can always build the url manually (via JS), but being lazy I'd prefer the browser do it for me. ;) Here is my sample form: <form name='config' action="test_form.html" method="get" enctype="application/x-www-form-urlencoded"> <input type="text" name="param1"> <input type="text" name="param2"> <input type="submit" value="Go"> </form>

  • Is there a standard for machine-readable descriptions of RESTful services?

    - by ecmendenhall
    I've interacted with a few RESTful APIs that provided excellent documentation for humans and descriptive URIs, but none of them seem to return machine-readable descriptions of themselves. It's not too tough to write methods of my own that assemble the right paths, and many language-specific API libraries are already just wrappers around RESTful requests. But the next level of abstraction seems really useful: a library that could read in an API's own machine readable documentation and generate the wrappers automatically, perhaps with a call to some standard URI like base_url + '/documentation' Are there any standards for machine-readable API documentation? Am I doing REST wrong? I am a relatively new programmer, but this seems like a good idea.

  • is it valid that a state machine can have more than one possible state for some transition?

    - by shankbond
    I have a requirement for a workflow which I am trying to model as a state machine, I see that there is more than one outcome of a given transition(or activity). Is it valid for a state machine to have more than one possible states, but only one state will be true at a given time? Note: This is my first attempt to model a state machine. Eg. might be: s1-t1-s2 s1-t1-s3 s1-t1-s4 where s1, s2, s3, s4 are states and t1 is transition/activity. A fictitious real world example might be: For a human, there can be two states: hungry, not hungry A basket can have only one item from: apple, orange. So, to model it we will have: hungry-pick from basket-apple found hungry-pick from basket-orange found apple found-eat-not hungry orange found-take juice out of it and then drink- not hungry

  • Resolving a Forward Declaration Issue Involving a State Machine in C++

    - by hypersonicninja
    I've recently returned to C++ development after a hiatus, and have a question regarding implementation of the State Design Pattern. I'm using the vanilla pattern, exactly as per the GoF book. My problem is that the state machine itself is based on some hardware used as part of an embedded system - so the design is fixed and can't be changed. This results in a circular dependency between two of the states (in particular), and I'm trying to resolve this. Here's the simplified code (note that I tried to resolve this by using headers as usual but still had problems - I've omitted them in this code snippet): #include <iostream> #include <memory> using namespace std; class Context { public: friend class State; Context() { } private: State* m_state; }; class State { public: State() { } virtual void Trigger1() = 0; virtual void Trigger2() = 0; }; class LLT : public State { public: LLT() { } void Trigger1() { new DH(); } void Trigger2() { new DL(); } }; class ALL : public State { public: ALL() { } void Trigger1() { new LLT(); } void Trigger2() { new DH(); } }; // DL needs to 'know' about DH. class DL : public State { public: DL() { } void Trigger1() { new ALL(); } void Trigger2() { new DH(); } }; class HLT : public State { public: HLT() { } void Trigger1() { new DH(); } void Trigger2() { new DL(); } }; class AHL : public State { public: AHL() { } void Trigger1() { new DH(); } void Trigger2() { new HLT(); } }; // DH needs to 'know' about DL. class DH : public State { public: DH () { } void Trigger1() { new AHL(); } void Trigger2() { new DL(); } }; int main() { auto_ptr<LLT> llt (new LLT); auto_ptr<ALL> all (new ALL); auto_ptr<DL> dl (new DL); auto_ptr<HLT> hlt (new HLT); auto_ptr<AHL> ahl (new AHL); auto_ptr<DH> dh (new DH); return 0; } The problem is basically that in the State Pattern, state transitions are made by invoking the the ChangeState method in the Context class, which invokes the constructor of the next state. Because of the circular dependency, I can't invoke the constructor because it's not possible to pre-define both of the constructors of the 'problem' states. I had a look at this article, and the template method which seemed to be the ideal solution - but it doesn't compile and my knowledge of templates is a rather limited... The other idea I had is to try and introduce a Helper class to the subclassed states, via multiple inheritance, to see if it's possible to specify the base class's constructor and have a reference to the state subclasse's constructor. But I think that was rather ambitious... Finally, would a direct implmentation of the Factory Method Design Pattern be the best way to resolve the entire problem?

  • Working with Visual Studio Web Development Server and IE6 in XP Mode on Windows 7

    - by Igor Milovanovic
    (Brian Reiter from  thoughtful computing has described this setup in this StackOverflow thread. The credit for the idea is entirely his, I have just extended it with some step by step descriptions and added some links and screenhots.)   If you are forced  to still support Internet Explorer 6, you can setup following combination on your machine to make the development for it less painful. A common problem if you are developing on Windows 7 is that you can’t install IE6 on your machine. (Not that you want that anyway). So you will probably end up working locally with IE8 and FF, and test your IE6 compatibility on a separate machine. This can get quite annoying, because you will have to maintain two different development environments, not have all the tools available, etc.   You can help yourself by installing IE6 in a Windows 7 XP Mode, which is basically just an Windows XP running in a virtual machine.   [1] Windows XP Mode installation   After you have installed and configured your XP mode (remember the security settings like Windows Update and antivirus software), you can add the shortcut to the IE6 in the virtual machine to the “all users” start menu. This shortcut will be replicated to your windows 7 XP mode start menu, and you will be able to seamlessly start your IE 6 as a normal window on your Windows 7 desktop.   [2] Configure IE6 for the Windows 7 installation   If you configure your XP – Mode to use (Shared Networking)  NAT, you can now use IE6 to browse the sites in the internet. (add proxy settings to IE6 if necessary)                       The problem now is that you can’t connect to the webdev server which is running on your local machine. This is because web development server is crippled to allow only local connections for security reasons.   In order to trick webdev in believing that the requests are coming from local machine itself you can use a light weight proxy like privoxy on your host (windows 7) machine and configure the IE6 running in the virtual host.   The first step is to make the host machine (running windows 7) reachable from the virtual machine (running XP). In order to do that, you can install the loopback adapter, and configure it to use an IP which is routable from the virtual machine. In example screenshot (192.168.1.66).   [3] How to install loopback adapter in Windows 7   After installation you can assign a static IP which is routable from the virtual machine (in example 192.168.1.66)                     The next step is to configure privoxy to listen on that IP address (using some not used port, in example, the default port 8118)   Change following line in config.txt:   # #      Suppose you are running Privoxy on an IPv6-capable machine and #      you want it to listen on the IPv6 address of the loopback device: # #        listen-address [::1]:8118 # # listen-address  192.168.1.66:8118   The last step is to configure the IE6 to use Privoxy which is running on your Windows 7 host machine as proxy for all addresses (including localhost)                             And now you can use your Windows7 XP Mode IE6 to connect to your Visual Studio’s webdev web server.                         [4] http://stackoverflow.com/questions/683151/connect-remotely-to-webdev-webserver-exe

  • Reinforcement learning toy project

    - by Betamoo
    My toy project to learn & apply Reinforcement Learning is: - An agent tries to reach a goal state "safely" & "quickly".... - But there are projectiles and rockets that are launched upon the agent in the way. - The agent can determine rockets position -with some noise- only if they are "near" - The agent then must learn to avoid crashing into these rockets.. - The agent has -rechargable with time- fuel which is consumed in agent motion - Continuous Actions: Accelerating forward - Turning with angle I need some hints and names of RL algorithms that suit that case.. - I think it is POMDP , but can I model it as MDP and just ignore noise? - In case POMDP, What is the recommended way for evaluating probability? - Which is better to use in this case: Value functions or Policy Iterations? - Can I use NN to model environment dynamics instead of using explicit equations? - If yes, Is there a specific type/model of NN to be recommended? - I think Actions must be discretized, right? I know it will take time and effort to learn such a topic, but I am eager to.. You may answer some of the questions if you can not answer all... Thanks

  • Algorithm to generate numerical concept hierarchy

    - by Christophe Herreman
    I have a couple of numerical datasets that I need to create a concept hierarchy for. For now, I have been doing this manually by observing the data (and a corresponding linechart). Based on my intuition, I created some acceptable hierarchies. This seems like a task that can be automated. Does anyone know if there is an algorithm to generate a concept hierarchy for numerical data? To give an example, I have the following dataset: Bangladesh 521 Brazil 8295 Burma 446 China 3259 Congo 2952 Egypt 2162 Ethiopia 333 France 46037 Germany 44729 India 1017 Indonesia 2239 Iran 4600 Italy 38996 Japan 38457 Mexico 10200 Nigeria 1401 Pakistan 1022 Philippines 1845 Russia 11807 South Africa 5685 Thailand 4116 Turkey 10479 UK 43734 US 47440 Vietnam 1042 for which I created the following hierarchy: LOWEST ( < 1000) LOW (1000 - 2500) MEDIUM (2501 - 7500) HIGH (7501 - 30000) HIGHEST ( 30000)

  • SVM Classification - minimum number of input sets for each class

    - by Amol Joshi
    Im trying to build an app to detect images which are advertisements from the webpages. Once I detect those Ill not be allowing those to be displayed on the client side. From the help that I got here in stackoverflow, I thought SVM is the best approach to my aim. So, I have coded SVM and an SMO myself. The dataset which I have got from UCI data repository has 3280 instances ( Link to Dataset- http://archive.ics.uci.edu/ml/datasets/Internet+Advertisements )where around 400 of them are from class representing Advertisement images and rest of them representing non-advertisement images. Right now Im taking the first 2800 input sets and training the SVM. But after looking at the accuracy rate I realised that most of those 2800 input sets are from non-advertisement image class. So Im getting very good accuracy for that class. So what can I do here? About how many input set shall I give to SVM to train and how many of them for each class? Thanks. Cheers. ( Basically made a new question because the context was different from my previous question. http://stackoverflow.com/questions/1991113/optimization-of-neural-network-input-data )

  • Nominal Attributes in LibSVM

    - by Chris S
    When creating a libsvm training file, how do you differentiate between a nominal attribute verses a numeric attribute? I'm trying to encode certain nominal attributes as integers, but I want to ensure libsvm doesn't misinterpret them as numeric values. Unfortunately, libsvm's site seems to have very little documentation. Pentaho's docs seem to imply libsvm makes this distinction, but I'm still not clear how it's made.

  • Calculating Nearest Match to Mean/Stddev Pair With LibSVM

    - by Chris S
    I'm new to SVMs, and I'm trying to use the Python interface to libsvm to classify a sample containing a mean and stddev. However, I'm getting nonsensical results. Is this task inappropriate for SVMs or is there an error in my use of libsvm? Below is the simple Python script I'm using to test: #!/usr/bin/env python # Simple classifier test. # Adapted from the svm_test.py file included in the standard libsvm distribution. from collections import defaultdict from svm import * # Define our sparse data formatted training and testing sets. labels = [1,2,3,4] train = [ # key: 0=mean, 1=stddev {0:2.5,1:3.5}, {0:5,1:1.2}, {0:7,1:3.3}, {0:10.3,1:0.3}, ] problem = svm_problem(labels, train) test = [ ({0:3, 1:3.11},1), ({0:7.3,1:3.1},3), ({0:7,1:3.3},3), ({0:9.8,1:0.5},4), ] # Test classifiers. kernels = [LINEAR, POLY, RBF] kname = ['linear','polynomial','rbf'] correct = defaultdict(int) for kn,kt in zip(kname,kernels): print kt param = svm_parameter(kernel_type = kt, C=10, probability = 1) model = svm_model(problem, param) for test_sample,correct_label in test: pred_label, pred_probability = model.predict_probability(test_sample) correct[kn] += pred_label == correct_label # Show results. print '-'*80 print 'Accuracy:' for kn,correct_count in correct.iteritems(): print '\t',kn, '%.6f (%i of %i)' % (correct_count/float(len(test)), correct_count, len(test)) The domain seems fairly simple. I'd expect that if it's trained to know a mean of 2.5 means label 1, then when it sees a mean of 2.4, it should return label 1 as the most likely classification. However, each kernel has an accuracy of 0%. Why is this? On a side note, is there a way to hide all the verbose training output dumped by libsvm in the terminal? I've searched libsvm's docs and code, but I can't find any way to turn this off.
