• Customize your icons in Windows 7 and Vista

  - by Matthew Guay

  Want to change out the icons on your desktop and more?  Personalizing your icons is a great way to make your PC uniquely yours,, and today we show you how to grab unique icons, and default Winnows. to be your own. Change the icon for Computer, Recycle Bin, Network, and your User folder Right-click on the desktop, and select Personalize. Now, click the “Change desktop icons” link on the left sidebar in the Personalization window. The window looks slightly different in Windows Vista, but the link is the same. Select the icon you wish to change, and click the Change Icon button.  In Windows 7, you will also notice a box to choose whether or not to allow themes to change icons, and you can uncheck it if you don’t want themes to change your icon settings. You can select one of the other included icons, or click browse to find the icon you want.  Click Ok when you are finished. Change Folder icons You can easily change the icon on most folders in Windows Vista and 7.  Simply right-click on the folder and select properties. Click the Customize tab, and then click the Change Icon button.  This will open the standard dialog to change your icon, so proceed as normal. This basically just creates a hidden desktop.ini file in the folder containing the following or similar data: [.ShellClassInfo]IconFile=%SystemRoot%\system32\SHELL32.dllIconIndex=20 You could manually create or edit the file if you choose, instead of using the dialogs. Simply create a new text file named desktop.ini with this same information, or edit the existing one.  Change the IconFile line to the location of your icon. If you are pointing to a .ico file you should change the IconIndex line to 0 instead. Note that this isn’t available for all folders, for instance you can’t use this to change the icon for the Windows folder.   In Windows 7, please note that you cannot change the icon of folder inside a library.  So if you are browsing your Documents library and would like to change an icon in that folder, right-click on it and select Open folder location.  Now you can change the icon as above. And if you would like to change a Library’s icon itself, then check out this tutorial: Change Your Windows 7 Library Icons the Easy Way Change the icon of any file type Want to make you files easier to tell apart?  Check out our tutorial on how to simply do this: Change a File Type’s Icon in Windows 7 Change the icon of any Application Shortcut To change the icon of a shortcut on your desktop, start menu, or in Explorer, simply right-click on the icon and select Properties. In the Shortcut tab, click the Change Icon button. Now choose one of the other available icons or click browse to find the icon you want. Change Icons of Running Programs in the Windows 7 taskbar If your computer is running Windows 7, you can customize the icon of any program running in the taskbar!  This only works on applications that are running but not pinned to the taskbar, so if you want to customize a pinned icon you may want to unpin it before customizing it.  But the interesting thing about this trick is that it can customize any icon anything running in the taskbar, including things like Control Panel! Right-click or click and push up to open the jumplist on the icon, and then right-click on the program’s name and select Properties.  Here we are customizing Control Panel, but you can do this on any application icon. Now, click Change Icon as usual. Select an icon you want (We switched the Control Panel icon to the Security Shield), or click Browse to find another icon.  Click Ok when finished, and then close the application window. The next time you open the program (or Control Panel in our example), you will notice your new icon on its taskbar icon. Please note that this only works on applications that are currently running and are not pinned to the taskbar.  Strangely, if the application is pinned to the taskbar, you can still click Properties and change the icon, but the change will not show up. Change the icon on any Drive on your Computer You can easily change the icon on your internal hard drives and portable drives with the free Drive Icon Changer application.  Simply download and unzip the file (link below), and then run the application as administrator by right-clicking on the icon and selecting “Run as administrator”. Now, select the drive that you want to change the icon of, and select your desired icon file. Click Save, and Drive Icon Changer will let you know that the icon has been changed successfully. You will then need to reboot your computer to complete the changes.  Simply click Yes to reboot. Now, our Drive icon is changed from this default image: to a Laptop icon we chose! You can do this to any drive in your computer, or to removable drives such as USB flash drives.  When you change these drives icons, the new icon will appear on any computer you insert the drive into.  Also, if you wish to remove the icon change, simply run the Drive Icon Changer again and remove the icon path. Download Drive Icon Changer This application actually simply creates or edits a hidden Autorun.inf file on the top of your drive.  You can edit or create the file yourself by hand if you’d like; simply include the following information in the file, and save it in the top directory of your drive: [autorun]ICON=[path of your icon] Remove Arrow from shortcut icons Many people don’t like the arrow on the shortcut icon, and there are two easy ways to do this. If you’re running the 32 bit version of Windows Vista or 7, simply use the Vista Shortcut Overlay Remover. If your computer is running the 64 bit version of Windows Vista or 7, use the Ultimate Windows Tweaker instead.  Simply select the Additional Tweaks section, and check the “Remove arrows from Shortcut Icons.” For more info and download links check out this article: Disable Shortcut Icon Arrow Overlay in Windows 7 or Vista Closing: This gives you a lot of ways to customize almost any icon on your computer, so you can make it look just like you want it to.  Stay tuned for more great desktop customization articles from How-to Geek!

• Convert DVD to MP4 / H.264 with HD Decrypter and Handbrake

  - by DigitalGeekery

  Are you looking for a way to convert your DVD collection to high quality MP4 files? Today we are going to take a look at using DVDFab HD Decrypter along with Handbrake to convert DVDs to MP4 using the H.264 codec.  Process Overview Handbrake is a great file conversion application, but it unfortunately can’t handle DVD copy protection. For that we will use DVDFab’s HD Decrypter. HD Decrypter is the always free portion of the DVDFab application. What HD Decrypter will do, is remove the copy protection from your DVD, and copy the Video-TS and Audio-TS folders to your hard drive. Once the copy protection is gone, we will use Handbrake to convert the files to MP4 format with H.264 compression. Note: You’ll get full access to all the options in DVDFab  during the 30 trial period. However, the HD Decrypter is free and will continue to work. Ripping the DVD Install both Handbrake and DVDFab HD Decrypter. (Download links below) Once the applications are installed, place your DVD into your DVD drive and open DVDFab. On the welcome screen, click “Start DVDFab.”   You’ll be prompted to choose your region. Click “OK.” The disc is analyzed and opened… You’ll be brought to the main interface. Make sure you have the Full Disc option selected at the left panel and “Copy DVD-Video (VIDEO_TS folder) is selected. Click “Start.” Don’t be confused by the “DVD to DVD” option pop up. We won’t actually be burning to DVD. The HD Decrypter portion of the DVDFab suite is part of the DVD to DVD option. Click “OK.” The DVD will be ripped to your hard drive. When the copy process is complete, you’ll be prompted to insert media to start the write process. We aren’t going to be burning to disc, so just click Cancel then close out of DVDFab.   Converting to MP4 Now we are ready to convert Open Handbrake and click on the “Source” button at the top left. Select DVD / VIDEO_TS folder from the drop down list. Now we need to browse for the location where DVDFab HD Decrypter copied your movie. By default, that location will be the \DVDFab\Temp\FullDisc directory in your Documents folder. For example, in Windows 7, it would be: C:\Users\%username%\Documents\DVDFab\Temp\FullDisc\[Name of Your DVD] Select the folder, and click “OK.” You may be prompted to set a default path in Handbrake. This is an optional step. Click “OK.” If you’d like to set a default destination folder, Go to Tools on the top menu, select Options. On the General tab, click “Browse” to select a destination output folder. Click “Close” when Finished.   Next, click the dropdown list next to “Title.” Select the title that matches the length of the movie. It’s possible you may have see more than one title with a similar length. If so, consult the DVD information, or a site like IMDB.com, to find the proper movie title length. Select your container under Output Settings. This will be your final output file extension. We will be using MP4 for this example. You also have the option of MKV.   If you didn’t set up a default destination folder, you’ll need to select one by clicking the “Browse” button. You can manually customize the output file name and change the output file extension to .mp4 (Unless you prefer the iPod friendly .m4v extension). Settings There are a variety of custom settings that can be changed either through the tabs listed under Output Settings, or by selecting one of the Presets to the right. If converting exclusively for any of the devices listed in the preset list, simply click on that device and the settings will be automatically applied in the Output Settings tabs. For more Universal (non-Apple) devices or output, select the Normal profile.   For the most part, the presets will suit quite nicely. However, you can further customize settings if you’d like. The Picture tab allows you to tweak the size or cropping region. You must change Anamorphic to Loose or Custom to change the size.   The Video tab allows you to choose your codec. H.264 is the default. You also have the option to choose a target (output) size. The Constant Quality is recommended to be set between 59% – 63%. Anything over 70% will likely result in an output file larger than the input without any improved quality. On the Subtitles tab, you can select an available subtitle from the dropdown list and click “Add” to add it to the output file. When you’ve finished any customizations you are ready to begin the conversion process. Click “Start.” A Command window will open and you can follow the process. You’ll probably want to find something to do in the meantime as the process could take a couple of hours. When the process completes, you’re ready to watch your video.   Although it’s a time consuming process that involves a couple steps, this method will give you high quality H.264 video files.

Tom is the Tom behind the AskTom column in Oracle Magazine and is also the author of Expert Oracle Database Architecture (Apress, 2005/2009) among other books Abstract: Big Data The term "big data" draws a lot of attention, but behind the hype there's a simple story. For decades, companies have been making business decisions based on transactional data stored in relational databases. However, beyond that critical data is a potential treasure trove of less structured data: weblogs, social media, email, sensors, and photographs that can be mined for useful information. This presentation will take a look at what Big Data is and means - and Oracle's strategy for handling it Abstract: What are we still doing wrong? I've given many best practices presentations in the last 10 years. I've given many worst practices presentations in the last 10 years. I've seen some things change over the last ten years and many other things stay exactly the same. In this talk - we'll be taking a look at the good and the bad - what we do right and what we continue to do wrong over and over again. We'll look at why "Why" is probably the right initial answer to most any question. We'll look at how we get to "Know what we Know", and why that can be both a help and a hindrance. We'll peek at "Best Practices" and tie them into what I term "Worst Practices". In short, a talk on the good and the bad.

• MDB listening a Topic in JBoss 5.1

  - by fool

  Hi, I have a topic configured correctly like this, in jboss 5.1: <mbean code="org.jboss.jms.server.destination.TopicService" name="jboss.messaging.destination:service=Topic,name=GreetingsTopic" xmbean-dd="xmdesc/Topic-xmbean.xml"> <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer </depends> <depends>jboss.messaging:service=PostOffice</depends> </mbean> I can see the topic being started in JBoss logs: 23:08:40,990 INFO [TopicService] Topic[/topic/GreetingsTopic] started, fullSize=200000, pageSize=2000, downCacheSize=2000 And I have this MDB: @MessageDriven(activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jmx.Topic"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/GreetingsTopic") }) public class GreetingsClientWebMDB implements MessageListener { ... ... } When I deploy the MDB, I'm getting a strange error: 3:09:30,781 ERROR [JmsActivation] Unable to reconnect org.jboss.resource.adapter.jms.inflow.JmsActivationSpec@1a1d638(ra=org.jboss.resource.adapter.jms.JmsResourceAdapter@1da5b5b destination=topic/GreetingsTopic destinationType=javax.jmx.Topic tx=true durable=false reconnect=10 provider=java:/DefaultJMSProvider user=null maxMessages=1 minSession=1 maxSession=15 keepAlive=60000 useDLQ=true DLQHandler=org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler DLQJndiName=queue/DLQ DLQUser=null DLQMaxResent=5) java.lang.ClassCastException: Object at 'topic/GreetingsTopic' in context {java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory, java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces:org.jboss.naming:org.jnp.interfaces} is not an instance of [class=javax.jms.Queue classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml} interfaces={interface=javax.jms.Destination classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml}}] object class is [class=org.jboss.jms.destination.JBossTopic classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml} interfaces={interface=javax.jms.Topic classloader=BaseClassLoader@91e143{vfsfile:/usr/local/jboss-5.1.0.GA/server/default/conf/jboss-service.xml}}] at org.jboss.util.naming.Util.checkObject(Util.java:338) at org.jboss.util.naming.Util.lookup(Util.java:223) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setupDestination(JmsActivation.java:464) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setup(JmsActivation.java:352) at org.jboss.resource.adapter.jms.inflow.JmsActivation.handleFailure(JmsActivation.java:292) at org.jboss.resource.adapter.jms.inflow.JmsActivation$SetupActivation.run(JmsActivation.java:733) at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:205) at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:260) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) I also try to use a deployment descriptor instead of annotations but with the same result.

• Accessing an object's fields without an active session

  - by Dave

  I'm using Hibernate 4.0.1.Final. Is it possible to access an object's fields if that object has been loaded via the org.hibernate.Session.load(Class clazz, Serializable id) method and there is no active session? I use this code to access an object by id … protected Object find(Class clazz, Serializable id) { Object obj = null; try { startOperation(); obj = session.load(clazz, id); tx.commit(); } catch (HibernateException e) { handleException(e); } finally { session.close(); } return obj; } but if I have that object without an active session, like with this code … final Organization foundOrg = orgDao.findById(org.getOrganizationId()); System.out.println(foundOrg.getName()); I get this error on the "System.out" line … org.hibernate.LazyInitializationException: could not initialize proxy - no Session at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:149) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:195) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:185) at org.myco.myproject.orgsclient.model.Organization_$$_javassist_0.getName(Organization_$$_javassist_0.java) at org.myco.myproject.orgsclient.dao.OrganizationDAOTest.testInsertSchool(OrganizationDAOTest.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

• Spring JPA and persistence.xml

  - by bmw0128

  I'm trying to set up a Spring JPA Hibernate simple example WAR for deployment to Glassfish. I see some examples use a persistence.xml file, and other examples do not. Some examples use a dataSource, and some do not. So far my understanding is that a dataSource is not needed if I have: <persistence-unit name="educationPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>com.coe.jpa.StudentProfile</class> <properties> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/COE" /> <property name="hibernate.connection.username" value="root" /> <property name="show_sql" value="true" /> <property name="dialect" value="org.hibernate.dialect.MySQLDialect" /> </properties> </persistence-unit> I can deploy fine, but my EntityManager is not getting injected by Spring. My applicationContext.xml: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="educationPU" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="StudentProfileDAO" class="com.coe.jpa.StudentProfileDAO"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="studentService" class="com.coe.services.StudentService"> </bean> My class with the EntityManager: public class StudentService { private String saveMessage; private String showModal; private String modalHeader; private StudentProfile studentProfile; private String lastName; private String firstName; @PersistenceContext(unitName="educationPU") private EntityManager em; @Transactional public String save() { System.out.println("*** em: " + this.em); //em is null this.studentProfile= new StudentProfile(); this.saveMessage = "saved"; this.showModal = "true"; this.modalHeader= "Information Saved"; return "successs"; } My web.xml: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> Are there any pieces I am missing to have Spring inject "em" in to StudentService?

• Advice on logic circuits and serial communications

  - by Spencer Ruport

  As far as I understand the serial port so far, transferring data is done over pin 3. As shown here: There are two things that make me uncomfortable about this. The first is that it seems to imply that the two connected devices agree on a signal speed and the second is that even if they are configured to run at the same speed you run into possible synchronization issues... right? Such things can be handled I suppose but it seems like there must be a simpler method. What seems like a better approach to me would be to have one of the serial port pins send a pulse that indicates that the next bit is ready to be stored. So if we're hooking these pins up to a shift register we basically have: (some pulse pin)-clk, tx-d Is this a common practice? Is there some reason not to do this? EDIT Mike shouldn't have deleted his answer. This I2C (2 pin serial) approach seems fairly close to what I did. The serial port doesn't have a clock you're right nobugz but that's basically what I've done. See here: private void SendBytes(byte[] data) { int baudRate = 0; int byteToSend = 0; int bitToSend = 0; byte bitmask = 0; byte[] trigger = new byte[1]; trigger[0] = 0; SerialPort p; try { p = new SerialPort(cmbPorts.Text); } catch { return; } if (!int.TryParse(txtBaudRate.Text, out baudRate)) return; if (baudRate < 100) return; p.BaudRate = baudRate; for (int index = 0; index < data.Length * 8; index++) { byteToSend = (int)(index / 8); bitToSend = index - (byteToSend * 8); bitmask = (byte)System.Math.Pow(2, bitToSend); p.Open(); p.Parity = Parity.Space; p.RtsEnable = (byte)(data[byteToSend] & bitmask) > 0; s = p.BaseStream; s.WriteByte(trigger[0]); p.Close(); } } Before anyone tells me how ugly this is or how I'm destroying my transfer speeds my quick answer is I don't care about that. My point is this seems much much simpler than the method you described in your answer nobugz. And it wouldn't be as ugly if the .Net SerialPort class gave me more control over the pin signals. Are there other serial port APIs that do?

• How to Configure SSL over Database in Spring?

  - by Sameer Malhotra

  Hi, I want to add SSL security in the Database layer. I am using Struts2.1.6, Spring 2.5, JBOSS 5.0 and Informix 11.5. Any idea how to do this? I have researched through a lot on the internet but could not find any solution. Please suggest! Here is my datasource and entity manager beans which is working perfect without SSL: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="INFORMIX" /> <property name="showSql" value="true" /> </bean> </property> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.informix.jdbc.IfxDriver" /> <property name="url" value="jdbc:informix-sqli://SERVER_NAME:9088/DB_NAME:INFORMIXSERVER=SERVER_NAME;DELIMIDENT=y;" /> <property name="username" value="username" /> <property name="password" value="password" /> <property name="minIdle" value="2" /> </bean> <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" lazy-init="false"> <property name="targetObject" ref="dataSource" /> <property name="targetMethod" value="addConnectionProperty" /> <property name="arguments"> <list> <value>characterEncoding</value> <value>UTF-8</value> </list> </property> </bean> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" scope="prototype"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" />

  Hello, I need something accurate I can plug equations in to if you can help. How would you apply the equation bellow? Thanks guys. AVERAGE VELOCITY AND DISPLACEMENT average velocity V=X/T displacement x=v*T more info example I have 30 seconds and a field that is 170 yards. What average velocity would I need my horse to travel at to reach the end of the field in 30 seconds. I moved the decimal places around and got this. Here's what I tried 'the return value is close, but not close enough' FLA here var TIMER:int = 10; var T:int = 0; var V:int = 5.6; var X:int = 0; var Xf:int = 17000/10*2; var timer:Timer = new Timer(TIMER,Xf); timer.addEventListener(TimerEvent.TIMER, incrementCounter); timer.start(); function formatCount(i:int):String { var fraction:int = Math.abs(i % 100); var whole:int = Math.abs(i / 100); return ("0000000" + whole).substr(-7, 7) + "." + (fraction < 10 ?

• Spring OpenSessionInViewFilter with @Transactional annotation

  - by Gautam

  This is regarding Spring OpenSessionInViewFilter using with @Transactional annotation at service layer. i went through so many stack overflow post on this but still confused about whether i should use OpenSessionInViewFilter or not to avoid LazyInitializationException It would be great help if somebody help me find out answer to below queries. Is it bad practice to use OpenSessionInViewFilter in application having complex schema. using this filter can cause N+1 problem if we are using OpenSessionInViewFilter does it mean @Transactional not required? Below is my Spring config file <context:component-scan base-package="com.test"/> <context:annotation-config/> <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basename" value="resources/messages" /> <property name="defaultEncoding" value="UTF-8" /> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="/WEB-INF/jdbc.properties" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${jdbc.dialect}</prop> <prop key="hibernate.show_sql">true</prop> <!-- <prop key="hibernate.hbm2ddl.auto">create</prop> --> </props> </property> </bean> <tx:annotation-driven /> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>

• mysql not starting

  - by Eiriks

  I have a server running on rackspace.com, it been running for about a year (collecting data for a project) and no problems. Now it seems mysql froze (could not connect either through ssh command line, remote app (sequel pro) or web (pages using the db just froze). I got a bit eager to fix this quick and rebooted the virtual server, running ubuntu 10.10. It is a small virtual LAMP server (10gig storage - I'm only using 1, 256mb ram -has not been a problem). Now after the reboot, I cannot get mysql to start again. service mysql status mysql stop/waiting I believe this just means mysql is not running. How do I get this running again? service mysql start start: Job failed to start No. Just typing 'mysql' gives: mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) There is a .sock file in this folder, 'ls -l' gives: srwxrwxrwx 1 mysql mysql 0 2012-12-01 17:20 mysqld.sock From googleing this for a while now, I see that many talk about the logfile and my.cnf.

• Ich bin jetzt Oracle Certified Associate!

  - by britta.wolf

  Jan Peuker, Absolvent der Hochschule Augsburg und University of Melbourne, hat vor kurzem das Zertifikat Oracle Database 10g Administrator Certified Associate erworben. Er hat uns netterweise mit diesem kleinen Text versorgt: "Die Oracle Zertifizierung beginnt üblicherweise mit dem Oracle Certified Associate. Für diese Zertifizierung ist noch keine tiefgehende Praxiserfahrung notwendig. Um den Titel des Oracle Database 11g Administrator Certified Associate zu erlangen, muss man eine Prüfung zu SQL (z.B. 1Z0-051) sowie eine Prüfung zur Administration (1Z0-045) ablegen. Beide Prüfungen dauern 2 Stunden und haben ca. 80 Fragen von denen etwa drei Viertel richtig beantwortet werden müssen, um zu bestehen. Eine Note gibt es nicht. Die Prüfungen finden immer elektronisch statt, die Software erlaubt das Überspringen und Markieren von Fragen. Während meiner Arbeitszeit nach meinem ersten Studium hatte ich häufig mit dem Oracle Datenbanksystem zu tun. Als ich mein Aufbaustudium an der University of Melbourne absolvierte, wurde mir von der Studienberaterin vorgeschlagen, den Kurs „Advanced Database Administration" zu belegen. Dieser beruht vollständig auf den offiziellen Oracle Trainings-Unterlagen zur Prüfung in Oracle Administration und erlaubt daher die Teilnahme an der offiziellen Zertifizierung. Im Gegensatz zur SQL Prüfung, deren Inhalt man sich gut selbst aneignen kann, hilft bei der Administrator-Zertifizierung ein echter Kurs mit Seminar ungemein. Viele Konzepte lassen sich schwer aus einem Buch lernen. Die Bestandteile der SGA oder das Anlegen von Benutzern mögen leicht zugänglich sein, Redo- und Undo-Management sowie Backup und Recovery kann man nur verstehen, wenn man Beispiele hat und diese an einem Testsystem (keine "kleine" XE-Datenbank, sondern eine "richtige" Datenbank mit Enterprise Manager) ausprobieren kann. Übermäßig viel Zeit habe ich keinesfalls investiert, weil das Grundsystem sehr logisch ist. Für die weniger nachvollziehbaren Bereiche, besonders die neuen Features, habe ich mir Fachbegriffe auf Lernkarten geschrieben und die Trainingsunterlagen am System durchgespielt. Die Prüfung war für mich überraschend schwer, weil das einfache "Tagesgeschäft" deutlich unterrepräsentiert ist. In den Multiple-Choice-Fragen werden viele Besonderheiten und Use-Cases abgefragt (online findet man viele Beispielfragen). Da beide Tests in Englisch sind, sollte man nicht nur in der Terminologie des Oracle Datenbanksystems sondern auch in Fachbegriffen der Datenbankwelt allgemein bewandert sein. Oft machen einzelne Wörter (z.B. redundant oder synchronized, redo log oder redo log buffer) die richtige Antwort aus, ein signifikanter Anteil der Fragen beruht auf Zeichnungen oder Diagrammen, die beschrieben werden müssen. So muss man z.B. anhand eines Log-Auszugs beurteilen, warum die Datenbank nicht sauber geschlossen wurde. Allgemeines Wissen über Datenbanksysteme hilft leider nicht viel, da überproportional viele Fragen zu Oracle-spezifischen Themen gestellt werden, wie z.B. Optimierungs-Dienste (ADDM), Flashback, SQL Loader und ein wenig PL/SQL. Die SQL Prüfung ist dagegen sehr geradlinig - was aber nicht einfacher heißt. Hier kommt es mehr auf Auswendiglernen von Syntax an, was mir persönlich nicht liegt. Vor allem als Anwendungsprogrammierer kennt man oft proprietäre SQL-Funktionen nicht, es fällt schwer, sich einzelne Datumsberechnungsfunktionen, Typkonvertierungen, Namespaces oder krude Join-Methoden zu merken. Auf all dies wird in der Prüfung aber sehr viel Wert gelegt. Auch hier wird man wieder mit zweideutigen Multiple-Choice Fragen konfrontiert, bei denen sich z.B. nur die Reihenfolge der Parameter unterscheidet. Zudem sind die Parameter auch nicht ausgeschrieben, sondern in einem Entity-Relationship-Diagramm gegeben, wobei man auf die richtigen Datentypen achten muss. Mir persönlich war die Zeit fast zu knapp bemessen, weil man bei vielen Fragen erst ein Diagramm, einen Datenauszug oder einen längeren Text lesen muss, um dann die richtigen Statements zu finden. Hier helfen Lernkarten also nur bedingt - stattdessen üben, üben, üben. Durch den relativ niedrigen Pass-Score von 70% kann man es sich leisten, unsichere Fragen zuerst zu überspringen und erst nachdem alle sicheren beantwortet sind, zu überdenken. Die Prüfung ist auf jeden Fall fair. Ich habe durch das Oracle-Zertifizierungsprogramm viel gelernt. Die Datenbanken unter meiner Aufsicht laufen deutlich performanter und liefern höhere Verfügbarkeit, weil ich Probleme eliminieren konnte, die mir vorher nicht klar waren. Eine klassische Misskonfiguration, volle Archive Logs, weil diese mit zu lange gehaltenem Flashback-Speicher kollidieren, konnte ich bereits in einer der ersten Stunden meines Kurses an der Uni Melbourne mit Hilfe meines Professors klären. Beide Prüfungen waren problemlos parallel zu anderen Prüfungen zu absolvieren. Empfehlen kann ich eine gründliche Online-Recherche aber auch die Oracle Press-Bücher, welche mit Prüfungsfragen am Ende jedes Kapitels aufwarten. So spart man sich Zeit und ist trotzdem gut vorbereitet. Auch wenn ich keine Laufbahn als Administrator einschlagen werde, bin ich froh die zugrundeliegende Technologie vieler Anwendungen besser zu verstehen. Für meine tägliche Arbeit als Anwendungsentwickler hat es mir vor allem geholfen, Oracle-Konzepte z.B. im Bereich der Transaktionssteuerung und Wiederherstellung zu verstehen und damit viele Open Source Produkte jetzt sinnvoller bewerten und empfehlen zu können." Eine Übersicht der Zertifizierungspfade finden Sie auf der Oracle University Webseite (dann einfach "Deutschland""auswählen und anschließend auf den Punkt "Zertifizierungen" klicken).

• Why Software Sucks...and What You Can Do About It – book review

  - by DigiMortal

      How do our users see the products we are writing for them and how happy they are with our work? Are they able to get their work done without fighting with cool features and crashes or are they just switching off resistance part of their brain to survive our software? Yeah, the overall picture of software usability landscape is not very nice. Okay, it is not even nice. But, fortunately, Why Software Sucks...and What You Can Do About It by David S. Platt explains everything. Why Software Sucks… is book for software users but I consider it as a-must reading also for developers and specially for their managers whose politics often kills all usability topics as soon as they may appear. For managers usability is soft topic that can be manipulated the way it is best in current state of project. Although developers are not UI designers and usability experts they are still very often forced to deal with these topics and this is how usability problems start (of course, also designers are able to produce designs that are stupid and too hard to use for users, but this blog here is about development). I found this book to be very interesting and funny reading. It is not humor book but it explains you all so you remember later very well what you just read. It took me about three evenings to go through this book and I am still enjoying what I found and how author explains our weird young working field to end users. I suggest this book to all developers – while you are demanding your management to hire or outsource usability expert you are at least causing less pain to end users. So, go and buy this book, just like I did. And… they thanks to mr. Platt :) There is one book more I suggest you to read if you are interested in usability - Don't Make Me Think: A Common Sense Approach to Web Usability, 2nd Edition by Steve Krug. Editorial review from Amazon Today’s software sucks. There’s no other good way to say it. It’s unsafe, allowing criminal programs to creep through the Internet wires into our very bedrooms. It’s unreliable, crashing when we need it most, wiping out hours or days of work with no way to get it back. And it’s hard to use, requiring large amounts of head-banging to figure out the simplest operations. It’s no secret that software sucks. You know that from personal experience, whether you use computers for work or personal tasks. In this book, programming insider David Platt explains why that’s the case and, more importantly, why it doesn’t have to be that way. And he explains it in plain, jargon-free English that’s a joy to read, using real-world examples with which you’re already familiar. In the end, he suggests what you, as a typical user, without a technical background, can do about this sad state of our software—how you, as an informed consumer, don’t have to take the abuse that bad software dishes out. As you might expect from the book’s title, Dave’s expose is laced with humor—sometimes outrageous, but always dead on. You’ll laugh out loud as you recall incidents with your own software that made you cry. You’ll slap your thigh with the same hand that so often pounded your computer desk and wished it was a bad programmer’s face. But Dave hasn’t written this book just for laughs. He’s written it to give long-overdue voice to your own discovery—that software does, indeed, suck, but it shouldn’t.

• LINQ und ArcObjects

  - by Marko Apfel

  LINQ und ArcObjects Motivation LINQ1 (language integrated query) ist eine Komponente des Microsoft .NET Frameworks seit der Version 3.5. Es erlaubt eine SQL-ähnliche Abfrage zu verschiedenen Datenquellen wie SQL, XML u.v.m. Wie SQL auch, bietet LINQ dazu eine deklarative Notation der Problemlösung - d.h. man muss nicht im Detail beschreiben wie eine Aufgabe, sondern was überhaupt zu lösen ist. Das befreit den Entwickler abfrageseitig von fehleranfälligen Iterator-Konstrukten. Ideal wäre es natürlich auf diese Möglichkeiten auch in der ArcObjects-Programmierung mit Features zugreifen zu können. Denkbar wäre dann folgendes Konstrukt: var largeFeatures = from feature in features where (feature.GetValue("SHAPE_Area").ToDouble() > 3000) select feature; bzw. dessen Äquivalent als Lambda-Expression: var largeFeatures = features.Where(feature => (feature.GetValue("SHAPE_Area").ToDouble() > 3000)); Dazu muss ein entsprechender Provider zu Verfügung stehen, der die entsprechende Iterator-Logik managt. Dies ist leichter als man auf den ersten Blick denkt - man muss nur die gewünschten Entitäten als IEnumerable<IFeature> liefern. (Anm.: nicht wundern - die Methoden GetValue() und ToDouble() habe ich nebenbei als Erweiterungsmethoden deklariert.) Im Hintergrund baut LINQ selbständig eine Zustandsmaschine (state machine)2 auf deren Ausführung verzögert ist (deferred execution)3 - d.h. dass erst beim tatsächlichen Anfordern von Entitäten (foreach, Count(), ToList(), ..) eine Instanziierung und Verarbeitung stattfindet, obwohl die Zuweisung schon an ganz anderer Stelle erfolgte. Insbesondere bei mehrfacher Iteration durch die Entitäten reibt man sich bei den ersten Debuggings verwundert die Augen wenn der Ausführungszeiger wie von Geisterhand wieder in die Iterator-Logik springt. Realisierung Eine ganz knappe Logik zum Konstruieren von IEnumerable<IFeature> lässt sich mittels Durchlaufen eines IFeatureCursor realisieren. Dazu werden die einzelnen Feature mit yield ausgegeben. Der einfachen Verwendung wegen, habe ich die Logik in eine Erweiterungsmethode GetFeatures() für IFeatureClass aufgenommen: public static IEnumerable GetFeatures(this IFeatureClass featureClass, IQueryFilter queryFilter, RecyclingPolicy policy) { IFeatureCursor featureCursor = featureClass.Search(queryFilter, RecyclingPolicy.Recycle == policy); IFeature feature; while (null != (feature = featureCursor.NextFeature())) { yield return feature; } //this is skipped in unit tests with cursor-mock if (Marshal.IsComObject(featureCursor)) { Marshal.ReleaseComObject(featureCursor); } } Damit kann man sich nun ganz einfach die IEnumerable<IFeature> erzeugen lassen: IEnumerable features = _featureClass.GetFeatures(RecyclingPolicy.DoNotRecycle); Etwas aufpassen muss man bei der Verwendung des "Recycling-Cursors". Nach einer verzögerten Ausführung darf im selben Kontext nicht erneut über die Features iteriert werden. In diesem Fall wird nämlich nur noch der Inhalt des letzten (recycelten) Features geliefert und alle Features sind innerhalb der Menge gleich. Kritisch würde daher das Konstrukt largeFeatures.ToList(). ForEach(feature => Debug.WriteLine(feature.OID)); weil ToList() schon einmal durch die Liste iteriert und der Cursor somit einmal durch die Features bewegt wurde. Die Erweiterungsmethode ForEach liefert dann immer dasselbe Feature. In derartigen Situationen darf also kein Cursor mit Recycling verwendet werden. Ein mehrfaches Ausführen von foreach ist hingegen kein Problem weil dafür jedes Mal die Zustandsmaschine neu instanziiert wird und somit der Cursor neu durchlaufen wird – das ist die oben schon erwähnte Magie. Ausblick Nun kann man auch einen Schritt weiter gehen und ganz eigene Implementierungen für die Schnittstelle IEnumerable<IFeature> in Angriff nehmen. Dazu müssen nur die Methode und das Property zum Zugriff auf den Enumerator ausprogrammiert werden. Im Enumerator selbst veranlasst man in der Reset()-Methode das erneute Ausführen der Suche – dazu übergibt man beispielsweise ein entsprechendes Delegate in den Konstruktur: new FeatureEnumerator( _featureClass, featureClass => featureClass.Search(_filter, isRecyclingCursor)); und ruft dieses beim Reset auf: public void Reset() {     _featureCursor = _resetCursor(_t); } Auf diese Art und Weise können Enumeratoren für völlig verschiedene Szenarien implementiert werden, die clientseitig restlos identisch nach obigen Schema verwendet werden. Damit verschmelzen Cursors, SelectionSets u.s.w. zu einer einzigen Materie und die Wiederverwendbarkeit von Code steigt immens. Obendrein lässt sich ein IEnumerable in automatisierten Unit-Tests sehr einfach mocken - ein großer Schritt in Richtung höherer Software-Qualität.4 Fazit Nichtsdestotrotz ist Vorsicht mit diesen Konstrukten in performance-relevante Abfragen geboten. Dadurch dass im Hintergrund eine Zustandsmaschine verwalten wird, entsteht einiges an Overhead dessen Verarbeitung zusätzliche Zeit kostet - ca. 20 bis 100 Prozent. Darüber hinaus ist auch das Arbeiten ohne Recycling schnell ein Performance-Gap. Allerdings ist deklarativer LINQ-Code viel eleganter, fehlerfreier und wartungsfreundlicher als das manuelle Iterieren, Vergleichen und Aufbauen einer Ergebnisliste. Der Code-Umfang verringert sich erfahrungsgemäß im Schnitt um 75 bis 90 Prozent! Dafür warte ich gerne ein paar Millisekunden länger. Wie so oft muss abgewogen werden zwischen Wartbarkeit und Performance - wobei für mich Wartbarkeit zunehmend an Priorität gewinnt. Zumeist ist sowieso nicht der Code sondern der Anwender die Bremse im Prozess.

• In the Groove: PASS Board Year 1, Q3

  - by Denise McInerney

  It's nine months into my first year on the PASS Board and I feel like I've found my rhythm. I've accomplished one of the goals I set out for the year and have made progress on others. Here's a recap of the last few months. Anti-Harassment Policy & Process Completed In April I began work on a Code of Conduct for the PASS Summit. The Board had several good discussions and various PASS members provided feedback. You can read more about that in this blog post. Since the document was focused on issues of harassment we renamed it the "Anti-Harassment Policy " and it was approved by the Board in August. The next step was to refine the guideliness and process for enforcement of the AHP. A subcommittee worked on this and presented an update to the Board at the September meeting. You can read more about that in this post, and you can find the process document here. Global Growth Expanding PASS' reach and making the organization relevant to SQL Server communities around the world has been a focus of the Board's work in 2012. We took the Global Growth initiative out to the community for feedback, and everyone on the Board participated, via Twitter chats, Town Hall meetings, feedback forums and in-person discussions. This community participation helped shape and refine our plans. Implementing the vision for Global Growth goes across all portfolios. The Virtual Chapters are well-positioned to help the organization move forward in this area. One outcome of the Global Growth discussions with the community is the expansion of two of the VCs from country-specific to language-specific. Thanks to the leadership in Brazil & Mexico for taking the lead here. I look forward to continued success for the Portuguese- and Spanish-language Virtual Chapters. Together with the Global Chinese VC PASS is off to a good start in making the VC's truly global. Virtual Chapters The VCs continue to grow and expand. Volunteers recently rebooted the Azure and Virutalization VCs, and a new  Education VC will be launching soon. Every week VCs offer excellent free training on a variety of topics. It's the dedication of the VC leaders and volunteers that make all this possible and I thank them for it. Board meeting The Board had an in-person meeting in September in San Diego, CA.. As usual we covered a number of topics including governance changes to support Global Growth, the upcoming Summit, 2013 events and the (then) upcoming PASS election. Next Up Much of the last couple of months has been focused on preparing for the PASS Summit in Seattle Nov. 6-9. I'll be there all week;  feel free to stop me if you have a question or concern, or just to introduce yourself.  Here are some of the places you can find me: VC Leaders Meeting Tuesday 8:00 am the VC leaders will have a meeting. We'll review some of the year's highlights and talk about plans for the next year Welcome Reception The VCs will be at the Welcome Reception in the new VC Lounge. Come by, learn more about what the VCs have to offer and meet others who share your interests. Exceptional DBA Awards Party I'm looking forward to seeing PASS Women in Tech VC leader Meredith Ryan receive her award at this event sponsored by Red Gate Session Presentation I will be presenting a spotlight session entitled "Stop Bad Data in Its OLTP Tracks" on Wednesday at 3:00 p.m. Exhibitor Reception This reception Wednesday evening in the Expo Hall is a great opportunity to learn more about tools and solutions that can help you in your job. Women in Tech Luncheon This year marks the 10th WIT Luncheon at PASS. I'm honored to be on the panel with Stefanie Higgins, Kevin Kline, Kendra Little and Jen Stirrup. This event is on Thursday at 11:30. Community Appreciation Party Thursday evening don't miss this event thanking all of you for everthing you do for PASS and the community. This year we will be at the Experience Music Project and it promises to be a fun party. Board Q & A Friday  9:45-11:15  am the members of the Board will be available to answer your questions. If you have a question for us, or want to hear what other members are thinking about, come by room 401 Friday morning.

• Upcoming User Group Events in 2011

  - by john.orourke(at)oracle.com

  At a recent customer event, someone asked me if Oracle had any plans to re-create the Hyperion Solutions Conference.  Unfortunately the answer is no.  With so many different product lines it would be challenging and costly for Oracle to run separate user conferences for every product line, and it would create too many events for customers with multiple products to attend.  So Oracle Open World is the company's main event for showcasing what's new and what's coming across all product lines.  If customers find Oracle OpenWorld too overwhelming or if the timing is bad, there are a number of other conferences, which are run by Oracle user groups and include a number of sessions focused on Oracle Hyperion EPM and BI products.  Here's a sneak preview of what's coming up for conferences in 2011 where you can network with other Hyperion users and learn what's new and what's coming in our products. Alliance 2011:  This conference is run by the Oracle Higher Education User Group (HEUG).  It's being held March 27 - 30th in lovely Denver, Colorado.  (a great location and time for skiers!)  This event is targeted at customers in Higher Education and Public Sector organizations and is expecting to draw over 3,500 attendees.  There will be a number of sessions focusing on Oracle Hyperion EPM and BI products in the Budgeting track, as well as the Reporting & BI track.  This includes product-focused sessions delivered by Oracle and partners, as well as case studies delivered by customers.  Here's a link to the registration page where you can get more information: http://www.heug.org/p/cm/ld/fid=255 Collaborate 2011:  This conference is run by three different user groups;  OAUG, IOUG and Quest.  It's being held April 10 - 14th in sunny Orlando, Florida.  (yes, sunshine and warmth!)  This event is targeted to customers with Oracle E-Business Suite, PeopleSoft, JD Edwards, Hyperion, Primavera and other products and is expected to draw over 5,000 attendees.  You'll find a number of sessions focused on Oracle Hyperion EPM and BI products in the BI/Data Warehousing/EPM track.  This includes product-focused sessions delivered by Oracle, our partners, and customers as well as a number of customer case studies.  There will also be an exhibit area with a number of demo pods focused on EPM and BI products.  Here's a link to the conference web site where you can get more information: http://collaborate.oaug.org/ Also, please note that the OAUG has a Hyperion SIG that runs focused EPM/Hyperion events throughout the year.  Here's a link to their web site where you can get more information: http://hyperionsig.oaug.org/ Kscope 2011:  Formerly the Kaleidoscope conference, this one is run by the Oracle Developer Tools User Group (ODTUG).  This conference is being held June 26 - 30th in Long Beach, CA. (surf's up!)  Historically, this event has focused on Oracle Development tools, but over the past few years the EPM and BI content has grown with over 100 sessions planned this year.  So this event is becoming a great venue for existing Hyperion customers to learn about the latest developments with Oracle Essbase, Hyperion Planning, Hyperion Financial Management, Oracle BI and other products.   You'll also find hands-on workshops, product demonstrations as well as EPM and BI Symposiums run by Oracle Development staff.  Here's a link to the web site where you can get more details.  http://www.kscope11.com/biepm UKOUG Conference Series:  EPM and Hyperion 2011:  For Hyperion customers in the UK, the UKOUG has a Hyperion SIG that runs a focused conference for EPM and Hyperion products.  The 2011 event is planned for June in London.  Here's a link to the web site for this event where you can get more information: http://hyperion.ukoug.org/default.asp?p=8461 In addition to these conferences, you can also find Oracle EPM and BI content at regional user group meetings globally as well as Marketing events run by Oracle.  Check the events page at www.oracle.com for the details on upcoming Marketing and regional User Group events.  So while Oracle will not be trying to replicate the Hyperion Solutions conference, the good news is that there are a number of other events available where customers can find out what's new and what's coming with Oracle EPM and BI products.  And these events are running at different times of the year in different locations - so you can pick the event that makes the most sense for your company from a timing and location standpoint. I'll be delivering a number of sessions at the Alliance and Collaborate conferences and hope to see many of our loyal customers and partners at these events.  And there's always Oracle OpenWorld coming up in October, for which the planning has already started.  I look forward to seeing you in 2011.

• Modifying Service URLs with LINQ to Twitter

  - by Joe Mayo

  It’s funny that two posts so close together speak about flexibility with the LINQ to Twitter provider.  There are certain things you know from experience on when to make software more flexible and when to save time.  This is another one of those times when I got lucky and made the right choice up front. I’m talking about the ability to switch URLs. It only makes sense that Twitter should begin versioning their API as it matures.  In fact, most of the entire API has moved to the v1 URL at “https://api.twitter.com/1/”, except for search and trends.  Recently, Twitter introduced the available and local trends, but hung them off the new v1, and left the rest of the trends API on the old URL. To implement this, I muscled my way into the expression tree during CreateRequestProcessor to figure out which trend I was dealing with; perhaps not elegant, but the code is in the right place and that’s what factories are for.  Anyway, the point is that I wouldn’t have to do this kind of stuff (as much fun as it is), if Twitter would have more consistency. Having went to Chirp last week and seeing the evolution of the API, it looks like my wish is coming true.  …now if they would just get their stuff together on the mess they made with geo-location and places… but again, that’s all transparent if your using LINQ to Twitter because I pulled all of that together in a consistent way so that you don’t have to. Normally, when Twitter makes a change, code breaks and I have to scramble to get the fixes in-place.  This time, in the case of a URL change, the adjustment is easy and no-one has to wait for me.  Essentially, all you need to do is change the URL passed to the TwitterContext constructor.  Here’s an example of instantiating a TwitterContext now: using (var twitterCtx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/")) The third parameter constructor is the SearchUrl, which is used for Search and Trend APIs. You probably know what’s coming next; another constructor, but with the SearchUrl parameter set to the new URL as follows: using (var twitterCtx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://api.twitter.com/1/")) One consequence of setting the URL this way is that you set the URL for both Trends and Search.  Since Search is still using the old URL, this is going to break for Search queries. You could always instantiate a special TwitterContext instance for Search queries, with the old URL set. Alternatively, you can use the TwitterContext’s SearchUrl property. Here’s an example: twitterCtx.SearchUrl = "https://api.twitter.com/1/"; var trends = (from trend in twitterCtx.Trends where trend.Type == TrendType.Daily && trend.Date == DateTime.Now.AddDays(-2).Date select trend) .ToList(); Notice how I set the SearchUrl property just-in-time for the query. This allows you to target the URL for each specific query. Whichever way you prefer to configure the URL, it’s your choice. So, now you know how to set the URL to be used for Trend queries and how to prevent whacking your Search queries. I’ll be updating the Trend API to use same URL as all other APIs soon, so the only API left to use the SearchUrl will be Search, but for the short term, it’s Trends and Search. Until I make this change, you’ll have a viable work-around by setting the URL yourself, as explained above. These were the Search and Trend URLs, but you might be curious about the second parameter of the TwitterContext constructor; that’s the URL for all other APIs (the BaseUrl), except for Trend and Search. Similarly, you can use the TwitterContext’s BaseUrl property to set the BaseUrl. Setting the BaseUrl can be useful when communicating with other services. In addition to Twitter changing URLs, the Twitter API has been adopted by other companies, such as Identi.ca, Tumblr, and  WordPress.  This capability lets you use LINQ to Twitter with any of these services.  This is a testament to the success of the Twitter API and it’s popularity. No doubt we’ll have hills and valleys to traverse as the Twitter API matures, but hopefully there will be enough flexibility in LINQ to Twitter to make these changes as transparent as possible for you. @JoeMayo

• OpenSSL Versions in Solaris

  - by darrenm

  Those of you have have installed Solaris 11 or have read some of the blogs by my colleagues will have noticed Solaris 11 includes OpenSSL 1.0.0, this is a different version to what we have in Solaris 10.  I hope the following explains why that is and how it fits with the expectations on binary compatibility between Solaris releases. Solaris 10 was the first release where we included OpenSSL libraries and headers (part of it was actually statically linked into the SSH client/server in Solaris 9).  At time we were building and releasing Solaris 10 the current train of OpenSSL was 0.9.7.  The OpenSSL libraries at that time were known to not always be completely API and ABI (binary) compatible between releases (some times even in the lettered patch releases) though mostly if you stuck with the documented high level APIs you would be fine.   For this reason OpenSSL was classified as a 'Volatile' interface and in Solaris 10 Volatile interfaces were not part of the default library search path which is why the OpenSSL libraries live in /usr/sfw/lib on Solaris 10.  Okay, but what does Volatile mean ? Quoting from the attributes(5) man page description of Volatile (which was called External in older taxonomy): Volatile interfaces can change at any time and for any reason. The Volatile interface stability level allows Sun pro- ducts to quickly track a fluid, rapidly evolving specif- ication. In many cases, this is preferred to providing additional stability to the interface, as it may better meet the expectations of the consumer. The most common application of this taxonomy level is to interfaces that are controlled by a body other than Sun, but unlike specifications controlled by standards bodies or Free or Open Source Software (FOSS) communities which value interface compatibility, it can not be asserted that an incompatible change to the interface specifica- tion would be exceedingly rare. It may also be applied to FOSS controlled software where it is deemed more important to track the community with minimal latency than to provide stability to our customers. It also common to apply the Volatile classification level to interfaces in the process of being defined by trusted or widely accepted organization. These are generically referred to as draft standards. An "IETF Internet draft" is a well understood example of a specification under development. Volatile can also be applied to experimental interfaces. No assertion is made regarding either source or binary compatibility of Volatile interfaces between any two releases, including patches. Applications containing these interfaces might fail to function properly in any future release. Note that last paragraph!  OpenSSL is only one example of the many interfaces in Solaris that are classified as Volatile.  At the other end of the scale we have Committed (Stable in Solaris 10 terminology) interfaces, these include things like the POSIX APIs or Solaris specific APIs that we have no intention of changing in an incompatible way.  There are also Private interfaces and things we declare as Not-an-Interface (eg command output not intended for scripting against only to be read by humans). Even if we had declared OpenSSL as a Committed/Stable interface in Solaris 10 there are allowed exceptions, again quoting from attributes(5): 4. An interface specification which isn't controlled by Sun has been changed incompatibly and the vast majority of interface consumers expect the newer interface. 5. Not making the incompatible change would be incomprehensible to our customers. In our opinion and that of our large and small customers keeping up with the OpenSSL community is important, and certainly both of the above cases apply. Our policy for dealing with OpenSSL on Solaris 10 was to stay at 0.9.7 and add fixes for security vulnerabilities (the version string includes the CVE numbers of fixed vulnerabilities relevant to that release train).  The last release of OpenSSL 0.9.7 delivered by the upstream community was more than 4 years ago in Feb 2007. Now lets roll forward to just before the release of Solaris 11 Express in 2010. By that point in time the current OpenSSL release was 0.9.8 with the 1.0.0 release known to be coming soon.  Two significant changes to OpenSSL were made between Solaris 10 and Solaris 11 Express.  First in Solaris 11 Express (and Solaris 11) we removed the requirement that Volatile libraries be placed in /usr/sfw/lib, that means OpenSSL is now in /usr/lib, secondly we upgraded it to the then current version stream of OpenSSL (0.9.8) as was expected by our customers. In between Solaris 11 Express in 2010 and the release of Solaris 11 in 2011 the OpenSSL community released version 1.0.0.  This was a huge milestone for a long standing and highly respected open source project.  It would have been highly negligent of Solaris not to include OpenSSL 1.0.0e in the Solaris 11 release. It is the latest best supported and best performing version.     In fact Solaris 11 isn't 'just' OpenSSL 1.0.0 but we have added our SPARC T4 engine and the AES-NI engine to support the on chip crypto acceleration. This gives us 4.3x better AES performance than OpenSSL 0.9.8 running on AIX on an IBM POWER7. We are now working with the OpenSSL community to determine how best to integrate the SPARC T4 changes into the mainline OpenSSL.  The OpenSSL 'pkcs11' engine we delivered in Solaris 10 to support the CA-6000 card and the SPARC T1/T2/T3 hardware is still included in Solaris 11. When OpenSSL 1.0.1 and 1.1.0 come out we will asses what is best for Solaris customers. It might be upgrade or it might be parallel delivery of more than one version stream.  At this time Solaris 11 still classifies OpenSSL as a Volatile interface, it is our hope that we will be able at some point in a future release to give it a higher interface stability level. Happy crypting! and thank-you OpenSSL community for all the work you have done that helps Solaris.
