  - by user1035890

  How can I change Twitter's icon height? I have another custom image, but the height stays the same. How do I fix this? https://dev.twitter.com/docs/tweet-button and I used the div method and not the iframe because I wanted to add the data-title I used this code: <script src="//platform.twitter.com/widgets.js" type="text/javascript"></script> <div> <a href="https://twitter.com/share" class="twitter-share-button" data-url="https://dev.twitter.com/pages/tweet_button" data-via="your_screen_name" data-text="Checking out this page about Tweet Buttons" data-related="anywhere:The Javascript API" data-count="vertical">Tweet</a> </div>

• Can I using cross-site XmlHttpRequest in Itunes LP environment?

  - by jameulrich

  Itunes is based on Webkit platform and we can't use cross-site XmlHttpRequest in JavaScript because of security policy. But, as a exception, we can do that with a special header. Here is source code and I did it successfully in Safari: /////////////// var url = 'http://mysite.net/canvas.php'; var mybody = "Arun"; var http = new XMLHttpRequest(); http.open("POST", url, true); http.setRequestHeader("X-PINGOTHER", "pingpong"); http.setRequestHeader('Content-Type', 'application/xml'); http.setRequestHeader("Content-length", mybody.length); http.setRequestHeader("Connection", "close"); http.send(mybody); /////////////// I sent xml data to my server and get return response successfully in Safari browser but i can't do it in iTunes LP environment. So what is the problems?

• Collections not read from hibernate/ehcache second-level-cache

  - by Mark van Venrooij

  I'm trying to cache lazy loaded collections with ehcache/hibernate in a Spring project. When I execute a session.get(Parent.class, 123) and browse through the children multiple times a query is executed every time to fetch the children. The parent is only queried the first time and then resolved from the cache. Probably I'm missing something, but I can't find the solution. Please see the relevant code below. I'm using Spring (3.2.4.RELEASE) Hibernate(4.2.1.Final) and ehcache(2.6.6) The parent class: @Entity @Table(name = "PARENT") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class ServiceSubscriptionGroup implements Serializable { /** The Id. */ @Id @Column(name = "ID") private int id; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private List<Child> children; public List<Child> getChildren() { return children; } public void setChildren(List<Child> children) { this.children = children; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Parent that = (Parent) o; if (id != that.id) return false; return true; } @Override public int hashCode() { return id; } } The child class: @Entity @Table(name = "CHILD") @Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, include = "all") public class Child { @Id @Column(name = "ID") private int id; @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "PARENT_ID") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private Parent parent; public int getId() { return id; } public void setId(final int id) { this.id = id; } private Parent getParent(){ return parent; } private void setParent(Parent parent) { this.parent = parent; } @Override public boolean equals(final Object o) { if (this == o) { return true; } if (o == null || getClass() != o.getClass()) { return false; } final Child that = (Child) o; return id == that.id; } @Override public int hashCode() { return id; } } The application context: <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>Parent</value> <value>Child</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</prop> <prop key="hibernate.hbm2ddl.auto">validate</prop> <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop> <prop key="hibernate.connection.charSet">UTF-8</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <!-- cache settings ehcache--> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.region.factory_class"> org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop> <prop key="hibernate.generate_statistics">true</prop> <prop key="hibernate.cache.use_structured_entries">true</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.transaction.factory_class"> org.hibernate.engine.transaction.internal.jta.JtaTransactionFactory</prop> <prop key="hibernate.transaction.jta.platform"> org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform</prop> </props> </property> </bean> The testcase I'm running: @Test public void testGetParentFromCache() { for (int i = 0; i <3 ; i++ ) { getEntity(); } } private void getEntity() { Session sess = sessionFactory.openSession() sess.setCacheMode(CacheMode.NORMAL); Transaction t = sess.beginTransaction(); Parent p = (Parent) s.get(Parent.class, 123); Assert.assertNotNull(p); Assert.assertNotNull(p.getChildren().size()); t.commit(); sess.flush(); sess.clear(); sess.close(); } In the logging I can see that the first time 2 queries are executed getting the parent and getting the children. Furthermore the logging shows that the child entities as well as the collection are stored in the 2nd level cache. However when reading the collection a query is executed to fetch the children on second and third attempt.

• Aldon and .Net Development

  - by David Stratton

  I'm looking for feedback from .Net developers who have experience with Aldon as a lifecycle management platform. We're seriously considering using Aldon for lifecycle management including source control, automated builds, etc. I know there are a lot of other options out there, but ours is primary an AS/400 shop (with AS/400 programmers outnumbering .Net developers 6 to 1), and Aldon is used already by our iSeries team. The benefit we're looking for is having one lifecycle management suite. Basically, I'm looking for opinions from people who have used Aldon and another set of tools (perhaps TFS, or a combination of SVN, Cruise Control, etc). If you've worked with both, do you have a recommendation on whether this is a good idea, or a bad idea? It's obviously a big choice, so any feedback would be helpful.

• (Newbie) Amazon Web Services Apache Server

  - by Samnsparky

  Hello! I am trying to get a feel for the costs imposed by running apache on AWS continually. Assuming that the service is scarcely used, does anyone know how many cpu hours that would eat up in a month just by sitting there and running? I understand that this is slightly impractical but I am trying to figure out what the cost of entry is to deploy an application on this platform (as compared to GAE). I suspect it to be small but I would like to know. Thank you for your help, Sam

• Missing Project Template after installing ASP.NET MVC 2

  - by DotNetHacker

  Hi, I have downloaded the ASP.NET MVC 2 Release version (using Web Platform Installer) as well as the downloading the file directly from the link in WPI. No error messages are reported after the install. When I go into Visual Web Developer and select Create New project I only the project reference to ASP.NET MVC version 1.0 and not version 2 (for clarity I have all the other project types, this is just in reference to the MVC projects). I have restarted, uninstalled and restarted and installed my PC multiple times and it still won't play. When clicking add a reference I can see the MVC.dll version 2.0.0.0 and add that no problem, but cannot manually upgrade the project since the ProjectTypeGuid used is not recognized. For reference I am using Visual Web Developer 2008 on Windows XP. ASP.NET MVC version 1.0 is working fine and without issue. Hope someone else can help. DNH

• Read binary data from a MDB-file running under LAMP

  - by BusterX

  I need to be able to connect to an MDB-file in a LAMP-environment (running on Linux) and ultimately insert converted data into a Mysql db. The data I need to access is stored as a BLOB (Long Binary Data according to Access) in the MDB file. I have not yet been able to actually have a look at the data but I have been told that the BLOB consists of byte strings. Something along the lines of: 0x1c 0x10 0x27 0x00 0x00 I need to parse the byte strings and convert these to a format that is human readable. I do have access to the documentation that explains the various byte strings. So this is really two questions: How do a get access to the MDB file via PHP* (running under LAMP) and read the BLOB (I do not have access to a Windows-platform)? What would be the best way to parse the binary data (in PHP*) once I am able to connect to the MDB-file? *Or are there other methods/languages that are more appropriate?

• Books on OpenGL ES targeted towards the iPhone

  - by Frank V

  There are a few posts on this site about OpenGL and the iPhone. Some even on books but I think you'll find this question is a bit different. I've searched and searched and have come to the conclusion that there are currently no books that specifically cover OpenGL ES on the iPhone platform. There are books that cover OpenGL ES [2.0] (note: the linked book covers OpenGL ES 2.0 but the iPhone uses OpenGL ES 1.1 which, I understand, is not backward compatible)... but they only have a small section for the iPhone (if any). What I want to know, is if anybody knows of any books that are forthcoming that specifically cover OpenGL ES 1.1 on the iPhone?

• Designing a frontend/backend architecture

  - by wrp

  What are some good information sources on designing programs with a client/server architecture? This is for development of a desktop application, not a Web service. The only books I have found on client/server apps deal with the case of a thin client connecting to a remote database. Two good examples of what I mean are Mathematica and SuperCollider. I'm looking for platform- and language-agnostic discussion of the issues in developing a frontend/backend system. Especially useful topics would be allocation of responsibilities and options for message passing.

• How to profile a silverlight application?

  - by rudigrobler

  Is their any profilers that support Silverlight? I have tried ANTS (Version 3.1) without any success? Does version 4 support it? Any other products I can try? Updated since the release of Silverlight 4, it is now possible to do full profiling on SL applications... check out this article on the topic At PDC, I announced that Silverlight 4 came with the new CoreCLR capability of being profile-able by the VS2010 profilers: this means that for the first time, we give you the power to profile the managed and native code (user or platform) used by a Silverlight application. woohoo. kudos to the CLR team. Sidenote: From silverlight 1-3, one could only use things like xperf (see XPerf: A CPU Sampler for Silverlight) which is very powerful to see the layout/text/media/gfx/etc pipelines, but only gives the native callstack.) From SilverLite (PDC video, TechEd Iceland, VS2010, profiling, Silverlight 4)

• Problems adding static library QT project

  - by Smek

  I have problems adding a static library to my Qt project. I have two project one is my static library and the other one is a Qt GUI project. As I add all classes to my GUI project as c++ or header files everything works just fine but I want this to be in a separate library. When I select the option to add a library I check External library then I select the .a file I have build and the folder where my header files can be found because I am working on a Mac I select Mac as the target platform. Then I click continue and then done. macx: LIBS += -L$$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/ -lMyLib INCLUDEPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include DEPENDPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include macx: PRE_TARGETDEPS += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/libMyLib.a When I build my GUI project I get the following error: The process "/usr/bin/make" exited with code 2.

• How to read GPU (graphic card) temperature?

  - by mr.b

  I am interested in a way how to read GPU temperature (graphics processing unit, main chip of graphic card), by using some video card driver API? Everyone knows that there two different chip manufacturers (popular ones, at least) - ATI and nVIDIA - so there are two different kinds of drivers to read temperature from. I'm interested in learning how to do it for each different card driver. Language in question is irrelevant - it could be C/C++, .NET platform, Java, but let's say that .NET is preferred. Anyone been doing this before?

• Implementation of APIs on diferent platforms

  - by b-gen-jack-o-neill

  OK, this is basicly just about any non-default OS API running on all different OS. But for my example let´s consider platform Windows, API SDL (Simple DirectMedia Layer). Actually this question came to my mind when I was reading about SDL. Originally, I thought that on Windows (and basicly any other OS) you must use OS API to make certain actions, like wrtiting to screen, creating window and so on, becouse that API knows what kernel calls and system subroutines calls it has to do. But when I read about SDL, I surprised me, becouse, you cannot make computer to do anything more than OS can, since you cannot acess HW directly, only thru OS API, from Console allocation to DirectX. So, my question actually is, how does this not-default-OS APIs work? Do they use (wrap) original system API (like MFC wraps win32 api)? Or, do they actually have direct acess to Windows kernel? Or is there any third, way in between? Thanks.

• How to automatically run in the background?

  - by Hun1Ahpu

  I'm not sure that it's not implemented yet, I hope that it is. But I know that in .Net programmers should manually run time-consuming task in the background thread. So every time we handle some UI event and we understand that this will take some time we also understand that this will hang UI thread and our application. And then we make all this Background work things and handle callbacks or whatever. So my question is: Is there in some language/platform a mechanism that will automatically run time-consuming tasks in the background and will do all related work itself? So we just write the code for handling specific UI event and this code will be somehow detected as time-consuming and will be executed in background. And if there isn't, then why?

• How to find GTK version in PHP-GTK2?

  - by aidave

  This one is driving me nuts. According to GTK's site, there exists GTK_MAJOR_VERSION, GTK_MINOR_VERSION, and GTK_MICRO_VERSION constants. However, none of these work: echo GTK_MAJOR_VERSION; echo GtK::MAJOR_VERISON; echo Gtk::GTK_MAJOR_VERSION; etc Also, Gtk::check_version(2,12,0) always fails even though I have a higher version. I'd like to simply get the actual version number and not rely on check_version, which seems unreliable. How can I do this? I need to do it within PHP, platform independent.

• Windows Phone 7 and C++/CLI

  - by Fabio Ceconello

  Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a similar experience? I'm not talking about code that does heavy low-level stuff - but there's a quite frequent use of templates and smart pointers.

Anyone knows how to fix this warning? UPDATE This problem also exists with gtk-demo , is it a gtk bug? Can someone verify that? Platform: windows XP UPDATE AGAIN This is indeed a gtk bug,which is un-fixable.

• Best data store for billions of rows

  - by Jody Powlette

  I need to be able to store small bits of data (approximately 50-75 bytes) for billions of records (~3 billion/month for a year). The only requirement is fast inserts and fast lookups for all records with the same GUID and the ability to access the data store from .net. I'm a SQL server guy and I think SQL Server can do this, but with all the talk about BigTable, CouchDB, and other nosql solutions, it's sounding more and more like an alternative to a traditional RDBS may be best due to optimizations for distributed queries and scaling. I tried cassandra and the .net libraries don't currently compile or are all subject to change (along with cassandra itself). I've looked into many nosql data stores available, but can't find one that meets my needs as a robust production-ready platform. If you had to store 36 billion small, flat records so that they're accessible from .net, what would choose and why?

• Twitter @anywhere API problems in firefox only

  - by Brian Scott

  I've implemented a simple example of the Twitter @anywhere api to display user hovercards. The example works great in Internet Explorer and Chrome. However, whenever I the page loads in Firefox I receive the following message in an alert window: To set up @anywhere, please provide a client ID Surely if the results are correct in Chrome and IE then everything must be setup correctly? Here is a simple code block which I've tested recreates the problem in Firefox only: <script src="http://platform.twitter.com/anywhere.js?id=WMg5kRMlIw807lRTsktnNQ&amp;v=1" type="text/javascript" > </script> <script type="text/javascript"> twttr.anywhere(onAnywhereLoad); function onAnywhereLoad(twitter) { twitter().hovercards(); }); </script>

• GlassFish JDO and global object

  - by bach

  Hi, I'm thinking about the GlassFish platform for my new app. My app env. doesn't have a big volume of data to handle, but a lot of users writing/reading the same data A very volotile portion of the data updates every 200milsec by diff users. Therefore I'd like that type of data to be in memory only and accessible to the whole app My questions: How do I use a global object in memory with GF? a. use a static variable object - for that I guess I need to make sure GF is running on only 1 JVM -- how to I configure GF to run on 1 jvm? b. use HttpContext - same as a. How do I persist to the DB? a. can I use JDO interface? How do I Schedule tasks to be performed in the future (something like the task queue in GAE) thanks, J.S. Bach

• Book recommendation for a Ruby dev learning Java

  - by cpjolicoeur

  I've been a Ruby developer for the past 4-5 years, and prior to that coded in Perl and a language called ProvideX for years. As hard as it may seem, I've never written a Java application short of the basic Hello World app probably a decade ago. I'm beginning to start doing some Android development to port some iPhone applications we did for a client over to the Android platform. As such, I'm wondering what the best reference book I can buy is to get up to speed quickly with the features (and peculiarities) of Java. There are numerous "Learn Ruby for Java programmers" out there, but not really any reference books for going the otherway of Ruby-to-Java. I'm looking for something preferably like the "Learn Perl the Hard Way" book. I know how to code, I just need a reference on learning the proper mechanics of Java after having done Ruby (and a bit of Obj-C) work exclusively for the past few years.
