  • How can I do a partial update (i.e., get isolated changesets) from subversion with subclipse?

    - by Ingvald
    If a file is committed several times with various changes, how can I fetch one change at a time, i.e., one changeset at a time? I use eclipse, subversion, and subclipse, and I can't change the former two for the time being (or the MS platform..). In my list/ overview a file seems to be listed only in the latest relevant changeset even if all changesets are listed. So an earlier changeset doesn't necessarily show the full set of files in the original commit, nor the original diff for a file in a commit. Update: I'm thinking about using changesets for simplified peer review, so I'd like the partial update represented for all the files commited in one changeset. It's easy to get diffs and specific revisions for specific files in eclipse, but I'd like to step through all the changes in one specific commit/ changeset in a practical manner.

  • Cross-compiling a Python script on Linux into a Windows executable

    - by Chinmay Kanchi
    I have a Python script that I'd like to compile into a Windows executable. Now, py2exe works fine from Windows, but I'd like to be able to run this from Linux. I do have Windows on my development machine, but Linux is my primary dev platform and I'm getting kind of sick of rebooting into Windows just to create the .exe. Any ideas? PS: I am aware that py2exe doesn't exactly compile the python file as much as package your script with the Python interpreter. But either way, the result is that you don't need Python installed to run the script.

  • is there a such thing as a randomly accessible pseudo-random number generator? (preferably open-sour

    - by lucid
    first off, is there a such thing as a random access random number generator, where you could not only sequentially generate random numbers as we're all used to, assuming rand100() always generates a value from 0-100: for (int i=0;i<5;i++) print rand100() output: 14 75 36 22 67 but also randomly access any random value like: rand100(0) would output 14 as long as you didn't change the seed rand100(3) would always output 22 rand100(4) would always output 67 and so on... I've actually found an open-source generator algorithm that does this, but you cannot change the seed. I know that pseudorandomness is a complex field; I wouldn't know how to alter it to add that functionality. Is there a seedable random access random number generator, preferably open source? or is there a better term for this I can google for more information? if not, part 2 of my question would be, is there any reliably random open source conventional seedable pseudorandom number generator so I could port it to multiple platforms/languages while retaining a consistent sequence of values for each platform for any given seed?

  • Debug IPhone App on 3.1.2 Phone

    - by Steblo
    Hello, I recently finished my first IPhone app and want to test it on my device now. I registered (and paid) for an Developer Account and managed to install the required certificates. Unfortunately my device is on firmware 3.1.2 (which I don't want to upgrade). My SDK only shows 3.1.3 as possible Target. As a result it can't be installed on my 3.1.2 device. Where can I set/change to target platform ? Otherwise my App would only run on the newest firmwares, right ? Instead I want to provide it to every User with OS 3.0

  • Connecting to TFS from iPhone

    - by Andrei
    Hi. I'm building this iPhone application to connect to a secured TFS server (one that requires authentication before letting you access its web services). When I access this server in a browser, the first thing it will do is ask me for credentials (username/password) and then connect me to the TFS server if those credentials are correct. I am using web services, as I don't think there is any other way to use TFS functionality for an outside platform...without changing stuff on the TFS host machine. So my questions are: Are there any web services that can be accessed to log into the TFS server? This authentication mechanism seems to be something common among multiple websites (I have seen it in other websites). Is there a way to replicate that authentication mechanism by sending an HTTP request? Is there a way to replicate this authentication procedure in any way? Thanks!

  • Very slow Eclipse 4.2, how to make it more responsive?

    - by Laurent
    I'm using Eclipse PDT on a rather large PHP project and the IDE is almost unusable. It takes nearly 30 seconds to open a file, and other actions, like selecting a folder in the file explorer, editing some text, etc. are equally slow. I followed various instructions to speed it up but nothing seems to work. This is my current eclipse.ini file. Any idea how I can improve it? -startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vmargs -server -Dosgi.requiredJavaVersion=1.7 -Xmn128m -Xms1024m -Xmx1024m -Xss2m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC System: Eclipse 4.2.0, Windows 7, 4 GB RAM

  • Anyone up to creating a tomcat based alternative for GAE?

    - by bach
    Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

  • Efficiency of while(true) ServerSocket Listen

    - by Submerged
    I am wondering if a typical while(true) ServerSocket listen loop takes an entire core to wait and accept a client connection (Even when implementing runnable and using Thread .start()) I am implementing a type of distributed computing cluster and each computer needs every core it has for computation. A Master node needs to communicate with these computers (invoking static methods that modify the algorithm's functioning). The reason I need to use sockets is due to the cross platform / cross language capabilities. In some cases, PHP will be invoking these java static methods. I used a java profiler (YourKit) and I can see my running ServerSocket listen thread and it never sleeps and it's always running. Is there a better approach to do what I want? Or, will the performance hit be negligible? Please, feel free to offer any suggestion if you can think of a better way (I've tried RMI, but it isn't supported cross-language. Thanks everyone

  • How do I set up derby in eclipse on Ubuntu?

    - by Everett
    The question basically says it all. I'm trying setup up JavaDB on my virtualbox running Ubuntu 9.10. I have the package downloaded and installed through the package manager, which I believe is the right to go about it. I have also installed the Eclipse's Data Platform Tools. I've been following this tutorial here: http://www.vogella.de/articles/EclipseDataToolsPlatform/article.html. I'm stuck at the driver definition step. When I select the driver template from the Name/Type tab and the jar file in the Jar List tab, the OK button is never enabled. At the top of the New Driver Definition dialog it says 'Unable to locate Jar/zip in the file system as specified by the driver definition: derby.jar.' I assume this is the problem. Any help or links to a better tutorial would be much appreciated.

  • Obfuscate strings in Python

    - by Caedis
    I have a password string that must be passed to a method. Everything works fine but I don't feel comfortable storing the password in clear text. Is there a way to obfuscate the string or to truly encrypt it? I'm aware that obfuscation can be reverse engineered, but I think I should at least try to cover up the password a bit. At the very least it wont be visible to a indexing program, or a stray eye giving a quick look at my code. I am aware of pyobfuscate but I don't want the whole program obfuscated, just one string and possibly the whole line itself where the variable is defined. Target platform is GNU Linux Generic (If that makes a difference)

  • What is your favourite Windbg tip/trick?

    - by user15071
    I have come to realize that Windbg is a very powerful debugger for the Windows platform & I learn something new about it once in a while. Can fellow Windbg users share some of their mad skills? ps: I am not looking for a nifty command, those can be found in the documentation. How about sharing tips on doing something that one couldn't otherwise imagine could be done with windbg? e.g. Some way to generate statistics about memory allocations when a process is run under windbg.

  • C# Assembly Xna.Framework.dll does not load

    - by jbsnorro
    When trying to load Microsoft.Xna.Framework.dll from any project, it throws a FileNotFoundException. The specified module could not be found. (Exception from HRESULT: 0x8007007E), with no innerException. Even the simple code like the following throws that exception: static void Main(string[] args) { Assembly.LoadFile(@"C:\Microsoft.Xna.Framework.dll"); } I run XP x64, but I've set the platform in the configuration manager to x86, because I know it shouldn't(doesn't) work on x64 or Any CPU. I've manually added the dll file to GAC, but that didn't solve the problem. I have also tried the M$ Assembly Binding Log Viewer to see if those logs had any useful information, but they didn't. Everything, the loading etc, was a success according to them. Any suggestions? please?

  • Distribute CouchDB as part of a Rails app?

    - by AaronThomson
    I am working on a Rails project and the Architect has asked me to investigate bundling CouchDB into to application so that it can be deployed by Capistrano across multiple platforms and managed by Rake. My expectation was that I could set up the Erlang VM on the various environments and then distribute the CouchDB application with Capistrano. However I can't find any option to download CouchDB without the Erlang runtime. I can, however see an option to build CouchDB from source which I assume is platform dependent. I am new to Erlang and CouchBD, am I missing something? Is there a way to bundle CouchDB into a Rails app and distribute it across multiple platforms?

  • The next step & technology towards web services.

    - by webzide
    Hi, My name is Dennis and I am pretty ambitious of creating the next big thing for the web. I have ideas but now I gotta get to work to learn the tools. I am learning Javascript. I don't know if next step for me to take is PHP or some suggests RUBY on Rails. What are the pros and cons. With your experience, I wish you could hint me to the right direction. Thanks. I don't mind working hard. My goal is to create a comprehensive and secure web service platform as well as a fast and user friendly UI.

  • Windows Azure Table Storage LINQ Operators

    - by Ryan Elkins
    Currently Table Storage supports From, Where, Take, and First. Are there plans to support any of the other 29 operators? If we have to code for these ourselves, how much of a performance difference are we looking at to something similar via SQL and SQL Server? Do you see it being somewhat comparable or will it be far far slower if I need to do a Count or Sum or Group By over a gigantic dataset? I like the Azure platform and the idea of cloud based storage. I like Windows Azure for the amount of data it can store and the schema-less nature of table storage. SQL Azure just won't work due to the high cost to storage space.

  • What are the best uses for each programming language?

    - by VirtuosiMedia
    I come from a web developer background, so I'm fairly familiar with PHP and JavaScript, but I'd eventually like to branch out into other languages. At this point, I don't have a particular direction or platform that I'm leaning toward as far as learning a new language or what I would use it for, but I would like to learn a little bit more about programming languages in general and what each one is used for. I've often heard (and I agree) that you should use the right tool for the job, so what jobs are each programming language best suited for? Edit: If you've worked with some of the newer or more obscure languages, please share for those as well.

  • Creating BlackBerry method stubs using wscompile on WSDL from ColdFusion

    - by Jim B
    I have been working on a BlackBerry application that consumes web services from ColdFusion 7. The Java ME SDK and the Java Wireless Toolkit both require that the generated WSDL be of the document/literal type. Fortunately, I have input on the web service development so I tried setting 'style="document"' in the cfcomponent tag. This generated a document/literal style WSDL but now wscompile generates the following errors in several places: Found unknown simple type: javax.xml.soap.SOAPElement Found unknown simple type: java.util.Calendar Any ideas why this is happening? The WSDL does get parsed correctly by the JWSDP tool but the stubs use namespaces that are not available in the J2ME platform. I would have thought ColdFusion WSDL would work more easily with other products in the Java family.

  • Metadata requirements for developers

    - by Paul James
    I'm tasked with providing a list of metadata requirements our data warehouse developers might need. This is not the business metadata (nice descriptions etc), but rather data required for change management (also known as impact assesment), data lineage etc. I've seen this article Meta Meta Data Data - Ralph Kimball but as I'm not the first person to do this I'm throwing it to the SO community. The actual question is this: What metadata do datawarehouse developers require to design, develop and manage change in ETL routines? PS: I'm trying to keep the answer platform agnostic but for context this is an Oracle database with PL/SQL and Datastage.

  • Failed to obtain JDBC Driver for MySQL under Tomcat environment

    - by Michael Mao
    Hi all: I've been trying to obtain the Driver class for JDBC connection to MySQL. The workstation is running on Linux, Fedora 10. I have manually set up the classpath variable for Java by CLI like this: bash-3.2$ echo $CLASSPATH /home/cmao/public_html/jsp/mysql-connector-java-5.1.12-bin.jar This shows that I've added the lastest mysql connection jar archive to my CLASSPATH variable. I've created a test JSP page which can be found here And source code for this page is: <%@page language="java"%> <%@page import="java.sql.*"%> <%@page import="java.util.*"%> <html> <head> <title>UTS JDBC MySQL connection test page</title> </head> <body> <% Connection con = null; out.print("Java version is : " + System.getProperty("java.version") + "<br />"); out.print("Tomcat version is : " + application.getServerInfo() + "<br />"); out.print("Servlet version is: " + application.getMajorVersion() + "<br />"); out.print("JSP version is : " + JspFactory.getDefaultFactory().getEngineInfo().getSpecificationVersion() +"<br />"); //out.print("Java classpath is : " + System.getProperty("java.class.path")+ "<br />"); //out.print("JSP classpath is : " + appliaction.getAttribute("org.apache.catalina.jsp_classpath") + "<br />"); //out.print("Tomcat classpath is : " + System.getProperty("org.apache.tomcat.common.classpath") + "<br />"); try { Class c = Class.forName("com.mysql.jdbc.Driver"); } catch(Exception e) { out.println("Error! Failed to obtain JDBC driver for MySQL... Missing class \"com.mysql.jdbc.Driver\"<br />"); } %> </body> </html> None of those commented out line would work, various Jsper Expetions would be thrown. You can check those Error pages from the following links: classpath Error page catalina Error page tomcat Error page It seems, from my limited knowledge of JSP and Servlet, the Tomcat environment "ignores" my Java CLASSPATH? In which case I cannot configure the MySQL JDBC package to let my Servlets(a JSP is but a Servlet anyway) work. I am not sure how to fix this issue. would it be better if I use an IDE like Eclipse or NetBeans and create a real Java "web app" so that everything can be "self-configured" by the usage of a web.config XML configuration file? So that I can certainly bypass this Tomcat environment restriction? Many thanks for the suggestions in advance.

  • What would you recommend for a large-scale Java data grid technology: Terracotta, GigaSpaces, Cohere

    - by cliff.meyers
    I've been reading up on so-called "data grid" solutions for the Java platform including Terracotta, GigaSpaces and Coherence. I was wondering if anyone has real-world experience working any of these tools and could share their experience. I'm also really curious to know what scale of deployment people have worked with: are we talking 2-4 node clusters or have you worked with anything significantly larger than that? I'm attracted to Terracotta because of its "drop in" support for Hibernate and Spring, both of which we use heavily. I also like the idea of how it decorates bytecode based on configuration and doesn't require you to program against a "grid API." I'm not aware of any advantages to tools which use the approach of an explicit API but would love to hear about them if they do in fact exist. :) I've also spent time reading about memcached but am more interested in hearing feedback on these three specific solutions. I would be curious to hear how they measure up against memcached in the event someone has used both.

  • How to assign permissions for Copy/Paste on windows

    - by jalchr
    Well, as everyone knows there is no way you can assign permissions for Copy/Paste of files on windows platform. I need to control the copy process from a central file server, in a way that helps me know: which user performed the copy Which files were copied where did he pasted them Total size of data copied Time of copy operation If user exceeds the allowed "Copy-Limit", a dialog box requests him to enter administrative credentials or deny him (as it would be configured) Store all this data in a file for later review or send by email. I need to collect this data by putting a utility program on the server itself, without any other installation on client computers. I know about monitoring the Clipboard, but which clipboard would it be? the user's clipboard or the server's clipboard ? And what about drag-drop operation, which doesn't even pass through the clipboard? Any knowledge of whether SystemFileWatcher is useful in such case ? Any ideas ?
