  • Xcode5 post-archive script for Sparkle package no longer works

    - by Flyingdiver
    Xcode 5 seems to have changed the way it stores the build application package (xxx.app) such that ditto no longer works. In the ../BuildProductsPath/Release/ directory, the app is actually a symlink to .../InstallationBuildProductsLocation/Applications/... MyApp.app - ~/Library/Developer/Xcode/DerivedData/MyApp-emwilkqhlayanxahjpexlpbbkato/Build/Intermediates/ArchiveIntermediates/MyApp/InstallationBuildProductsLocation/Applications/MyApp This breaks the ditto command I was using to create a zip file of the application to put on my Sparkle update server. Anyone have an updated script for building the Sparkle XML and ZIP files? Or know what environment variable I need to use to locate my actual binary after the Archive phase?

  • logrotate compress files after the postrotate script

    - by Thomas
    I have an application generating a really heavy big log file every days (~800MB a day), thus I need to compress them but since the compression takes time, I want that logrotate compress the file after reloading/sending HUP signal to the application. /var/log/myapp.log { rotate 7 size 500M compress weekly postrotate /bin/kill -HUP `cat /var/run/myapp.pid 2>/dev/null` 2>/dev/null || true endscript } Is it already the case that the compression takes place after the postrotate (which would be counter-intuitive)? If not Can anyone tell me if it's possible to do that without an extra command script (an option or some trick)? Thanks Thomas

  • Easy way to parse a url in C++ cross platform?

    - by Andrew Bucknell
    I need to parse a url to get the protocol host path and query in an application I am writing in c++. The application is intended to be cross platform. Im surprised I cant find anything that does this in boost or poco libraries. Is it somewhere obvious Im not looking? Any suggestions on appropriate open source libs? Or is this something I just have to do my self? Its not super complicated but it seems such a common task I am surprised there isnt a common solution.

  • JVM tuning on Amazon EC2

    - by Shadowman
    We will be deploying a production application to Amazon EC2 very shortly. Initially, we'll just be using a "small" instance, but have plans to scale up not long afterwards. My question is, has any investigation been done on JVM tuning for the EC2 environment? Are there any specific changes that we should make to our JVM parameters to compensate for quirks/characteristics of Amazon EC2? Or, do the normal tuning methodologies apply here as they would in a physical environment? Our application will be deployed on Tomcat 6.x. It is built using JBoss Seam 2.2.x, and uses PostgreSQL 8.x as the backend database. Any advice you can give is greatly appreciated!

  • Can a Site get a Virus from using Curl?

    - by Mark Tyler
    I have a script which uses simple php curl requests to get the contents from rss/atom feeds.... now my question is it possible that by using curl, is there a chance i might get a virus? Let's say I do a php curl request to a rss feed in feedburner (I know this site does not contain any viruses, but this is only an example) and let's say this site has a malicious virus of some kind. Is there a chance that I might inherit that virus too? If yes, what precautions can I do to make sure something like that never happens. This is the php code I am currently using to fetch the RSS $headers [] = 'Connection: Keep-Alive'; $headers [] = 'Content-type: application/x-www-form-urlencoded; charset=utf-8'; $headers [] = 'Accept-Encoding: application/xhtml+xml,application/xml,text/xml,text/html;q=0.9,*/*;q=0.8'; $ch = curl_init($url); //curl_setopt($ch, CURLOPT_USERAGENT,'Phenoix/0.1.3 (Feed Parser Beta; Beta ; Allow like Gecko) Build/20111112'); curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1'); //curl_setopt($ch, CURLOPT_REFERER, "http://google.com/auto/clogger"); //curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate' ); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers ); //curl_setopt($channel, CURLOPT_HEADER, 0); curl_setopt($ch, CURLINFO_HEADER_OUT, 1); curl_setopt($ch, CURLOPT_VERBOSE, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($ch, CURLOPT_FAILONERROR, 1); //allow cookie $cookie_file = "cookie1.txt"; curl_setopt($ch, CURLOPT_COOKIESESSION, true); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file); $xml = curl_exec($ch); if(curl_error($ch)){ //$text .= "Error while updating.

  • Is SQL server the best DB for Storing and comparing images in database for a small ecommerce applica

    - by iecut
    I have been trying to create a small e-commerce web based application using MS Dot Net framework. The application will let the user allow to store the image of their product that they want to sell or purchase, then they will have the option to upload the image of a particular product and compare that image with the similar images in the database. So my two main concerns are: - Is MS SQL a good option to store and compare the images. - Is the any other better database that can do the same work with less complexity of work and that is also easy to integrate with MS dot net framework.

  • How can I limit the number of connections to an mssql server from my tomcat deployed java applicatio

    - by CJ
    Hi, I have an application that is deployed on tomcat on server A and sends queries to a huge variety of mssql databases on an server B. I am concerned that my application could overload this mssql database server and would like some way to preventing it making requests to connect to any database on that server if some arbitrary number of connections were already in existence and unclosed. I am looking at using connection pooling but am under the impression that this will only pool connections to a specific database on the mssql server, I want to control the total of these combined connections that will occur to many different databases (incidentally I can only find out the names of individual db's dynamically as they change day to day). Will connection pooling take care of this for me, are am I looking at this from the wrong perspective? I have no access to the configuration of the mssql server. Links to tutorials or working examples of your suggested solution are most welcome! Thanks, Caroline

  • WPF - Handling events from user control in View Model

    - by Vitaly
    I’m building a WPF application using MVVM pattern (both are new technologies for me). I use user controls for simple bits of reusable functionality that doesn’t contain business logic, and MVVM pattern to build application logic. Suppose a view contains my user control that fires events, and I want to add an event handler to that event. That event handler should be in the view model of the view, because it contains business logic. The question is – view and the view model are connected only by binding; how do I connect an event handler using binding? Is it even possible (I suspect not)? If not – how should I handle events from a control in the view model? Maybe I should use commands or INotifyPropertyChanged?

  • Use Tomcat with Java SecurityManager?

    - by pauline
    I'm writing a web application that is supposed to run on Tomcat on Ubuntu. On Ubuntu, Tomcat is per default configured to run with the Java SecurityManager. Besides my own web application, there will only be some well known third party web applications related to my own, like the BIRT report engine. If one of the web applications fails or gets compromised, it may take down all the others without harm, because they all belong together. What I don't wont to happen is that a compromised web app compromises the system itself, like calling rm -r / Do I need to use the java security manager to achieve this? Or is it only necessary to protect one web app from the other? I'd really like to prevent the effort to create .policy files for all the 3rd party web applications I intend to use.

  • Scaling larger Image problem.

    - by krishna
    Hi, I m developing flex application, in which I want to Draw Image from User local hard-drive to the canvas of size 640x360. User can choose Image of bigger resolution & is scaled to Canvas size. But if user selected images of larger resolution like 3000x2000, the scaling take lot time & freezes the application until scale done. Is there any method to scale image faster or kind of threading can be done? I am using matrix to scale Image as below: var mat:Matrix = new Matrix(); var scalex:Number = canvasScreen.width/content.width; var scaley:Number = canvasScreen.height/content.height; mat.scale(scalex,scaley); canvasScreen.graphics.clear(); canvasScreen.graphics.beginBitmapFill(content.bitmapData,mat);

  • Building a minimal plugin architecture in Python.

    - by dF
    I have an application, written in Python, which is used by a fairly technical audience (scientists). I'm looking for a good way to make the application extensible by the users, i.e. a scripting/plugin architecture. I am looking for something extremely lightweight. Most scripts, or plugins, are not going to be developed and distributed by a third-party and installed, but are going to be something whipped up by a user in a few minutes to automate a repeating task, add support for a file format, etc. So plugins should have the absolute minimum boilerplate code, and require no 'installation' other than copying to a folder (so something like setuptools entry points, or the Zope plugin architecture seems like too much.) Are there any systems like this already out there, or any projects that implement a similar scheme that I should look at for ideas / inspiration?

  • Operating System for first production windows server code?

    - by Unkwntech
    I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

  • How to collect user opinions about software

    - by alga
    I have written a small .net Windows Forms application. And now I decided to get opinions or comments from users. User will just write something in a input form and click a send button. I want to use the most easiest way. I don't want to host any webservices or another applications for gathering the information. Also I don't have a database. Nothing. I just want to know what people think about the application. How would you do it?

  • [SWT/RCP] Alpha blending is slow on linux

    - by elgcom
    we are developing an SWT/RCP(Eclipse 3.5) application on both Windows and Linux (on identical hardware). The application is a GIS app which shows several layered maps(PNG images) rendered with alpha blending. org.eclipse.draw2d.Graphics.setAlpha(...); org.eclipse.draw2d.Graphics.drawImage(...); On Windows the performance is pretty good, but on Linux it is very poor. is that a Linux(GTK/KDE) problem? or is there any workaround to improve the performance on Linux?

  • ASP.NET - Themes and Relative Referencing

    - by user70192
    Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

  • how to compare/validate sql schema

    - by Ron Harlev
    I'm looking for a way to validate the SQL schema on a production DB after updating an application version. If the application does not match the DB schema version, there should be a way to warn the user and list the changes needed. Is there a tool or a framework (to use programatically) with built-in features to do that? Or is there some simple algorithm to run this comparison? Update: Red gate lists "from $395". Anything free? Or more foolproof than just keeping the version number?

  • How does bundler work (in general)?

    - by MAP
    Hello, I'm pretty new to Ruby/Rails but I was taking a look at bundler and was wondering how it works exactly. Do you install a full set of gems like normal gem install XYZand then use the Gemfile to pull a certain subset of those gems for use with a specific application? Or do you not install gems normally anymore and just include them in the Gemfile and then do a bundle install to include them all in a bundle that is then used with your application? Thank you so much for taking the time to answer this, I'm just a little confused on what bundler's functionality is exactly. -- MAP

  • php mysql database users connection handling

    - by aviv
    What is the best way to handle mysql database users connection in PHP? I have a web server running a PHP application on MySQL. I have created a database user for the application: dbuser1 with limited access - only for query, insert and update tables. No alter table. Now the question is, should i use the same dbuser1 widely in my scripts, so if there are 100 current people using my system and hence 100 scripts running parallel they all connect to the database with the same dbuser1? or should i create a few users and assign each script a different user or load-balance between the dbusers ?

  • Data mining logs to locate a bug

    - by gooli
    I'm working on a data distribution application which receives data from a source and distributes that data to multiple target application. After successfully distributing several messages each second for 8 days, it missed a single message and did not deliver it properly to the clients. As I was looking at the logs I tried to find something there that was special for the time the miss happend - either in the data, its rate or some other condition but couldn't find anything. Is there any data mining technique I can use to identify how that specific event differs from other events?

  • Configuration file reading. Best practice

    - by Andrew Florko
    Application stores configuration data in custom section of configuration file. This information is used all over the application. Nowadays I use helper static class to to provide access like this (some code omitted or simplified): [XmlRoot("webSiteSection")] public class WebSiteConfig : IConfigurationSectionHandler { public static WebSiteConfig Current { get { if (_current == null) _current = (WebSiteConfig) ConfigurationManager.GetSection("webSiteSection"); return _current; } } [XmlElement("section1")] public Section1 Section1 { get; set; } [XmlElement("section2")] public Section2 Section2 { get; set; } ... public object Create(object parent, object configContext, XmlNode section) { var serializer = new XmlSerializer(typeof(WebSiteConfig)); return serializer.Deserialize(new XmlNodeReader(section)); } } Then I use it like this <%: WebSiteConfig.Current.Section1.Value1 %> <%: WebSiteConfig.Current.Section1.Value2 %> What do you think of it? I find it usable because it keeps code simple, but also confused as IConfigurationSectionHandler is deprecated since .NET Framework 2.0

  • MySQL or SQL Server

    - by user203708
    I'm creating an application that I want to run on either MySQL or SQL Server (not both at the same time) I've created two PHP classes DatabaseMySQL and DatabaseSQLSVR and I'd like my application to know which database class to use based on a constant set up at install. define(DB_TYPE, "mysql"); // or "sqlsrv" I'm trying to think of the best way to handle this. My thought is to do an "if else" wherever I instantiate the database: $db = (DB_TYPE == "mysql") ? new DatabaseMySQL : new DatabaseSQLSVR; I know there has to be a better way of doing this though. Suppose I want to add a third database type later; I'll have to go and redo all my code. Yuk!! Any help would be much appreciated. Thank

    I am using subsonic repository pattern(2.1) for asp.net mvc application.In my application,there are many repositories like categoryRepository,Blogrepository etc.Inside each of this repository i am calling subsonic's DB.Select().From()...ExecuteReader() and then loading domain objects from those reader. In the controller action i make multiple calls from these repositories for e.g. List<IBlog> blogs=_blogRepository.GetHottestBlogs(); List<ICategory> categories=_categoryRepository.GetAll(); do i have to implement any unitofwork pattern for this ?.My doubt is that how subsonic performs each operation DB.Update/Insert/Select .Is a TransactionScope is enough for batch update or do i have to use SharedDbConnectionScope to get better performance?
