  • 13.04 Temp Save, rt3290, Kernel downgrade

    - by user170534
    It's kind of a multiplying but I didn't wanted to open more than one topics. I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off. I was a short time arch user and with openbox and firefox it was about 60 to 70 degrees; wanted to turn to a stable release just for this reason. acpitz-virtual-0 Adapter: Virtual device temp1: +50.0°C radeon-pci-0100 Adapter: PCI adapter temp1: -128.0°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +56.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +54.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +55.0°C (high = +87.0°C, crit = +105.0°C) The temperature is not seriously high yet can be lower. Another issue is my wifi card, rt3290: The rt2800pci module is fine and all that but the download performance is pretty bad alongside of annoying signal range and the prop. driver gives a conf error about some specific rt2860 code and integrales in pci_dev file. If I blank off the error making variables, module loads but the driver is unused. Since the driver is old, I was thinking of downgrading the kernel of raring to 3.7 or may be 3.6. Should &-or can I?

  • How can I speed up boot on one of my machines?

    - by Korneel Bouman
    I have a Gateway all in one machine (2 gig Intel Core 2 Duo T7250 dual core processor, 2 gig RAM - full specs) on which I installed 10.10. Once it has booted it's fine, but it takes forever to boot. This is what happens: 1. Boot starts with cursor flashing for about 10-15 seconds 2. Cursor disappears for 1.5 - 2 minutes 3. Cursor reappears, blinks a few seconds more, boot finishes in another 10 seconds 4. Login screen I have another machine with marginal better specs that boots up in no time (basically the above minus the two minute delay). Things I've done: enabled verbose mode for grub nothing is showing until after 2 minute pause. checked syslog last message before pause is a message from alsa saying the process is already running (or something similar... going from memory here...) It could be something sound related as the built in speakers are not working (sound card is recognized though and headphones work). Anyway, it's not the end of the world, but it's annoying and I'd like to know what's going on... Many thanks, and let me know if more info is needed.

  • Best way to generate pieces in match-3 games, and then tracking them?

    - by JonLim
    I've been working on a match-3 style game in Actionscript using Flixel, and so far, I've been able to build the core mechanics of the game, including board generation, piece generation, piece swapping and movement, and checking algorithms. However, I am now running into issues with clearing out pieces and letting the above pieces fall down and generating new pieces. The reason I'm running into these issues is that when all of the pieces are generated, the pertinent values (position, sprite ID, and sprite object) are pushed into an array that helps me track everything, all the time. When pieces are moved, I swap the values of the corresponding arrays and life goes on. And that array is the core of my problem: if a row in the middle of the board clears out, ideally, all of the pieces above the cleared pieces should fall down to take their place and new pieces are generated at the top and also fall into place. Except if I try to do that now, all the pieces can fall down, but then I'd have to bump all of their values into the right arrays (oh god my head) and then generate new pieces and fit THOSE into the correct place in the array. Am I overthinking this? Or is there a far better way to track these pieces? Thanks guys!

  • JMS messaging implementation

    - by Gandalf StormCrow
    I've been struggling with this "simple" task for more expirienced people, I'm stuck for 2 days now need help. I've changed things arround like zillion times now, finally I stumbled upon this spring JMS tutorial. What I want to do, Send a message and receive it. I've been also reading this book chapter 8 on messaging. It really nicely explains 2 type of messaging and there is nice example for publish-and-subscribe type but now example for point-to-point messaging( this is the one I need). I'm able to send message to the queue on my own, but don't have a clue how to receive thats why I tried with this spring tutorial here is what I've got so far : SENDER : package quartz.spring.com.example; import java.util.HashMap; import java.util.Map; import javax.jms.ConnectionFactory; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Queue; import javax.jms.Session; import org.springframework.jms.core.MessageCreator; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.JmsTemplate102; import org.springframework.jms.core.MessagePostProcessor; public class JmsQueueSender { private JmsTemplate jmsTemplate; private Queue queue; public void setConnectionFactory(ConnectionFactory cf) { this.jmsTemplate = new JmsTemplate102(cf, false); } public void setQueue(Queue queue) { this.queue = queue; } public void simpleSend() { this.jmsTemplate.send(this.queue, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage("hello queue world"); } }); } public void sendWithConversion() { Map map = new HashMap(); map.put("Name", "Mark"); map.put("Age", new Integer(47)); jmsTemplate.convertAndSend("testQueue", map, new MessagePostProcessor() { public Message postProcessMessage(Message message) throws JMSException { message.setIntProperty("AccountID", 1234); message.setJMSCorrelationID("123-00001"); return message; } }); } } RECEIVER : package quartz.spring.com.example; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; public class ExampleListener implements MessageListener { public void onMessage(Message message) { if (message instanceof TextMessage) { try { System.out.println(((TextMessage) message).getText()); } catch (JMSException ex) { throw new RuntimeException(ex); } } else { throw new IllegalArgumentException("Message must be of type TextMessage"); } } } applicationcontext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd"> <bean id="sender" class="quartz.spring.com.example.JmsQueueSender" init-method="sendWithConversion" /> <bean id="receiver" class="quartz.spring.com.example.ExampleListener" init-method="onMessage" /> </beans> Didn't really know that learning curve for this is so long, I mean the idea is very simple: Send message to the destination queue Receive message from the destination queue To receive messages, you do the following(so does book say): 1 Locate a ConnectionFactory, typically using JNDI. 2 Use the ConnectionFactory to create a Connection. 3 Use the Connection to create a Session. 4 Locate a Destination, typically using JNDI. 5 Use the Session to create a MessageConsumer for that Destination. Once you’ve done this, methods on the MessageConsumer enable you to either query the Destination for messages or to register for message notification. Can somebody please direct me towards right direction, is there a tutorial which explains in details how to receive message from the queue?I have the working send message code, didn't post it here because this post is too long as it is.

  • WCF Service, Java JApplet client, transport error 405

    - by Juan Zamudio
    Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time. The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned. I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results. Here is an example of the Java class where everything is working public class TestSoaMetro { public String TestMethod(){ String result=null; IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); try { result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } Here is the example of the JApplet where I get the error: public class TestSoaMetroApplet extends JApplet { public void init() { Container content = getContentPane(); content.setBackground(Color.white); content.setLayout(new FlowLayout()); String result= this.TestMethod(); JLabel label = new JLabel(result); content.add(label); } public String TestMethod(){ String result=null; IDigitalSignatureService aa = null; try { aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

  • Thread Synchronisation 101

    - by taspeotis
    Previously I've written some very simple multithreaded code, and I've always been aware that at any time there could be a context switch right in the middle of what I'm doing, so I've always guarded access the shared variables through a CCriticalSection class that enters the critical section on construction and leaves it on destruction. I know this is fairly aggressive and I enter and leave critical sections quite frequently and sometimes egregiously (e.g. at the start of a function when I could put the CCriticalSection inside a tighter code block) but my code doesn't crash and it runs fast enough. At work my multithreaded code needs to be a tighter, only locking/synchronising at the lowest level needed. At work I was trying to debug some multithreaded code, and I came across this: EnterCriticalSection(&m_Crit4); m_bSomeVariable = true; LeaveCriticalSection(&m_Crit4); Now, m_bSomeVariable is a Win32 BOOL (not volatile), which as far as I know is defined to be an int, and on x86 reading and writing these values is a single instruction, and since context switches occur on an instruction boundary then there's no need for synchronising this operation with a critical section. I did some more research online to see whether this operation did not need synchronisation, and I came up with two scenarios it did: The CPU implements out of order execution or the second thread is running on a different core and the updated value is not written into RAM for the other core to see; and The int is not 4-byte aligned. I believe number 1 can be solved using the "volatile" keyword. In VS2005 and later the C++ compiler surrounds access to this variable using memory barriers, ensuring that the variable is always completely written/read to the main system memory before using it. Number 2 I cannot verify, I don't know why the byte alignment would make a difference. I don't know the x86 instruction set, but does mov need to be given a 4-byte aligned address? If not do you need to use a combination of instructions? That would introduce the problem. So... QUESTION 1: Does using the "volatile" keyword (implicity using memory barriers and hinting to the compiler not to optimise this code) absolve a programmer from the need to synchronise a 4-byte/8-byte on x86/x64 variable between read/write operations? QUESTION 2: Is there the explicit requirement that the variable be 4-byte/8-byte aligned? I did some more digging into our code and the variables defined in the class: class CExample { private: CRITICAL_SECTION m_Crit1; // Protects variable a CRITICAL_SECTION m_Crit2; // Protects variable b CRITICAL_SECTION m_Crit3; // Protects variable c CRITICAL_SECTION m_Crit4; // Protects variable d // ... }; Now, to me this seems excessive. I thought critical sections synchronised threads between a process, so if you've got one you can enter it and no other thread in that process can execute. There is no need for a critical section for each variable you want to protect, if you're in a critical section then nothing else can interrupt you. I think the only thing that can change the variables from outside a critical section is if the process shares a memory page with another process (can you do that?) and the other process starts to change the values. Mutexes would also help here, named mutexes are shared across processes, or only processes of the same name? QUESTION 3: Is my analysis of critical sections correct, and should this code be rewritten to use mutexes? I have had a look at other synchronisation objects (semaphores and spinlocks), are they better suited here? QUESTION 4: Where are critical sections/mutexes/semaphores/spinlocks best suited? That is, which synchronisation problem should they be applied to. Is there a vast performance penalty for choosing one over the other? And while we're on it, I read that spinlocks should not be used in a single-core multithreaded environment, only a multi-core multithreaded environment. So, QUESTION 5: Is this wrong, or if not, why is it right? Thanks in advance for any responses :)

  • Tomcat/Hibernate Problem "SEVERE: Error listenerStart"

    - by JSteve
    I downloaded working example of hibernate (with maven) and installed it on my tomcat, it worked. Then I created a new web project in MyEclipse, added hibernate support and moved all source files (no jar) to this new project and fixed package/paths wherever was necessary. My servlets are responding correctly but when I add "Listener" in web.xml, tomcat returns error "Error ListenerStart" on startup and my application doesn't start. I've carefully checked all packages, paths and classes, they look good. Error message is also not telling anything more except these two words Here is complete tomcat startup log: 17-Jun-2010 12:13:37 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-8810 17-Jun-2010 12:13:37 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 293 ms 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardService start INFO: Starting service Catalina 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/6.0.20 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart 17-Jun-2010 12:13:37 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/addressbook] startup failed due to previous errors 17-Jun-2010 12:13:37 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on http-8810 17-Jun-2010 12:13:37 PM org.apache.jk.common.ChannelSocket init INFO: JK: ajp13 listening on /0.0.0.0:8009 17-Jun-2010 12:13:37 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/22 config=null 17-Jun-2010 12:13:37 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 446 ms My web.xml is: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <listener> <listener-class>addressbook.util.SessionFactoryInitializer</listener-class> </listener> <filter> <filter-name>Session Interceptor</filter-name> <filter-class>addressbook.util.SessionInterceptor</filter-class> </filter> <filter-mapping> <filter-name>Session Interceptor</filter-name> <servlet-name>Country Manager</servlet-name> </filter-mapping> <servlet> <servlet-name>Country Manager</servlet-name> <servlet-class>addressbook.managers.CountryManagerServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Country Manager</servlet-name> <url-pattern>/countrymanager</url-pattern> </servlet-mapping> </web-app> Can somebody either help me figure out what I am doing wrong? or point to some resource where I may get some precise solution of my problem?

  • Magento Admin Custom Sales Report

    - by Ela
    Hi, I have to develop a module to export collection of product,order,customer combined attributes. So i thought rather than modifying the core sales report for this purpose better to do a custom functionality. These are the steps that i did but i am not able to produce it. Used magento 1.4.1 version for this. Under /var/www/magento141/app/code/core/Mage/Reports/etc/adminhtml.xml Added these lines for menus. <ereaders translate="title" module="reports"> <title>EReader Sales Report</title> <children> <ereaders translate="title" module="reports"> <title>Sales Report</title> <action>adminhtml/report_sales/ereaders</action> </ereaders> </children> </ereaders> Under /var/www/magento141/app/design/adminhtml/default/default/layout/sales.xml Added these lines for filter condition. <adminhtml_report_sales_ereaders> <update handle="report_sales"/> <reference name="content"> <block type="adminhtml/report_sales_sales" template="report/grid/container.phtml" name="sales.report.grid.container"> <block type="adminhtml/store_switcher" template="report/store/switcher/enhanced.phtml" name="store.switcher"> <action method="setStoreVarName"><var_name>store_ids</var_name></action> </block> <block type="sales/adminhtml_report_filter_form_order" name="grid.filter.form"> ---- </block> </block> </reference> </adminhtml_report_sales_ereaders> And then copied the needed block,model files from sales and renamed all of them into ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/. Then placed action for ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/controllers/Report/SalesController.php public function ereadersAction() { $this->_title($this->__('Reports'))->_title($this->__('Sales'))->_title($this->__('EReaders Sales')); $this->_showLastExecutionTime(Mage_Reports_Model_Flag::REPORT_ORDER_FLAG_CODE, 'ereaders'); $this->_initAction() ->_setActiveMenu('report/sales/ereaders') ->_addBreadcrumb(Mage::helper('adminhtml')->__('EReaders Sales Report'), Mage::helper('adminhtml')->__('EReaders Sales Report')); $gridBlock = $this->getLayout()->getBlock('report_sales_ereaders.grid'); $filterFormBlock = $this->getLayout()->getBlock('grid.filter.form'); $this->_initReportAction(array( $gridBlock, $filterFormBlock )); $this->renderLayout(); } Here when i use var_dump == //var_dump($this-getLayout()-getBlock('report_sales_ereaders.grid')); am getting bool(false) only. It does not call the ereaders grid, instead of its still loading blocks and grids from Sales only. I searched most of the files related to report, am not still able to find out the problem. Hope many of you gone through these sort of issues, please can anyone tell me where am making mistake or missing something.

  • Do I need to manually create indexes for a DBIx::Class belongs_to relationship

    - by Dancrumb
    I'm using the DBIx::Class modules for an ORM approach to an application I have. I'm having some problems with my relationships. I have the following package MySchema::Result::ClusterIP; use strict; use warnings; use base qw/DBIx::Class::Core/; our $VERSION = '1.0'; __PACKAGE__->load_components(qw/InflateColumn::Object::Enum Core/); __PACKAGE__->table('cluster_ip'); __PACKAGE__->add_columns( # Columns here ); __PACKAGE__->set_primary_key('objkey'); __PACKAGE__->belongs_to( 'configuration' => 'MySchema::Result::Configuration', 'config_key'); __PACKAGE__->belongs_to( 'cluster' => 'MySchema::Result::Cluster', { 'foreign.config_key' => 'self.config_key', 'foreign.id' => 'self.cluster_id' } ); As well as package MySchema::Result::Cluster; use strict; use warnings; use base qw/DBIx::Class::Core/; our $VERSION = '1.0'; __PACKAGE__->load_components(qw/InflateColumn::Object::Enum Core/); __PACKAGE__->table('cluster'); __PACKAGE__->add_columns( # Columns here ); __PACKAGE__->set_primary_key('objkey'); __PACKAGE__->belongs_to( 'configuration' => 'MySchema::Result::Configuration', 'config_key'); __PACKAGE__->has_many('cluster_ip' => 'MySchema::Result::ClusterIP', { 'foreign.config_key' => 'self.config_key', 'foreign.cluster_id' => 'self.id' }); There are a couple of other modules, but I don't believe that they are relevant. When I attempt to deploy this schema, I get the following error: DBIx::Class::Schema::deploy(): DBI Exception: DBD::mysql::db do failed: Can't create table 'test.cluster_ip' (errno: 150) [ for Statement "CREATE TABLE `cluster_ip` ( `objkey` smallint(5) unsigned NOT NULL auto_increment, `config_key` smallint(5) unsigned NOT NULL, `cluster_id` char(16) NOT NULL, INDEX `cluster_ip_idx_config_key_cluster_id` (`config_key`, `cluster_id`), INDEX `cluster_ip_idx_config_key` (`config_key`), PRIMARY KEY (`objkey`), CONSTRAINT `cluster_ip_fk_config_key_cluster_id` FOREIGN KEY (`config_key`, `cluster_id`) REFERENCES `cluster` (`config_key`, `id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `cluster_ip_fk_config_key` FOREIGN KEY (`config_key`) REFERENCES `configuration` (`config_key`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB"] at test_deploy.pl line 18 (running "CREATE TABLE `cluster_ip` ( `objkey` smallint(5) unsigned NOT NULL auto_increment, `config_key` smallint(5) unsigned NOT NULL, `cluster_id` char(16) NOT NULL, INDEX `cluster_ip_idx_config_key_cluster_id` (`config_key`, `cluster_id`), INDEX `cluster_ip_idx_config_key` (`config_key`), PRIMARY KEY (`objkey`), CONSTRAINT `cluster_ip_fk_config_key_cluster_id` FOREIGN KEY (`config_key`, `cluster_id`) REFERENC ES `cluster` (`config_key`, `id`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `cluster_ip_fk_config_key` FOREIGN KEY (`config_key`) REFERENCES `configuration` (`conf ig_key`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB") at test_deploy.pl line 18 From what I can tell, MySQL is complaining about the FOREIGN KEY constraint, in particular, the REFERENCE to (config_key, id) in the cluster table. From my reading of the MySQL documentation, this seems like a reasonable complaint, especially in regards to the third bullet point on this doc page. Here's my question. Am I missing something in the DBIx::Class module? I realize that I could explicitly create the necessary index to match up with this foreign key constraint, but that seems to be repetitive work. Is there something I should be doing to make this occur implicitly?

  • Cloning whole form elements after clicking button

    - by FreshPro
    I have this following form <form action="" class="form-horizontal"> <div id="wrapper"> <div class="row-fluid"> <div class="span6"> <div class="control-group"> <label class="control-label"><?=$core->l("default_comm_type");?></label> <div class="controls"> <select id="fld_default_comm_type" name="fld_default_comm_type[]" defaultValue="-1" class="m-wrap span10" field="fld_default_comm_type" appEditor="true"> <?=combo_creator::render_default_comm_types()?> </select> </div> </div> </div> <div class="span4 checkerAlign"> <div class="control-group"> <div class="controls"> <?=$core->l("is_active");?> </div> </div> </div> <div class="span2 checkerAlign"><input type="checkbox" name="fld_active[]" id="fld_active" editType="booleanEdit" appEditor="true"/></div> </div> <div><a href="#" id="addMore">Add Row</a></div> </div> The question is when user clicks Add Row button, I need to create a copy of this form elements inside <div id="wrapper"> How can i do that? EDIT: SOLVED <form action="" class="form-horizontal" id="wrapper"> <div class="row-fluid"> <div class="span6"> <div class="control-group"> <label class="control-label"><?=$core->l("default_comm_type");?></label> <div class="controls"> <select id="fld_default_comm_type" name="fld_default_comm_type[]" defaultValue="-1" class="m-wrap span10" field="fld_default_comm_type" appEditor="true"> <?=combo_creator::render_default_comm_types()?> </select> </div> </div> </div> <div class="span4 checkerAlign"> <div class="control-group"> <div class="controls"> <?=$core->l("is_active");?> </div> </div> </div> <div class="span2 checkerAlign"><input type="checkbox" name="fld_active[]" id="fld_active" editType="booleanEdit" appEditor="true"/></div> </div> <a href="#" data-action="add">add</a> <a href="#" data-action="delete">delete</a> </form> In the Js part: jQuery("#addMore").click(function(){ var contents = jQuery("form").html(); jQuery("#test").append(contents); }); When add is clicked it inserts form elements just as I wanted and when delete is clicked it deletes elements. Thank you for the tips guys Problem solved! Thanks guys.

  • Spring - PropertiesPlaceholderConfigurer not finding properties file

    - by sat
    Not sure what could be wrong. I had an app that worked all along with this <context:property-placeholder location="classpath:my.properties"/> No problems finding the properties file and hooking things up. Now, I needed to encrypt some fields in the properties file. So I ended up writing the custom PropertiesPlaceholderConfigurer and tried to wire it up like this <bean class="com.mycompany.myapp.PropertiesPlaceholderConfigurer"> <property name="location" value="classpath:my.propeties"/> </bean> With this configuration, Spring complains that it cannot find the properties file. java.io.FileNotFoundException: class path resource [my.propeties] cannot be opened because it does not exist What in addition should be done? The custom placeholder configurer package com.mycompany.myapp; import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer; import org.springframework.util.ObjectUtils; import java.util.Enumeration; import java.util.Properties; public class PropertiesPlaceholderConfigurer extends PropertyPlaceholderConfigurer{ @Override protected void convertProperties(Properties props) { Enumeration<?> propertyNames = props.propertyNames(); while (propertyNames.hasMoreElements()) { String propertyName = (String) propertyNames.nextElement(); String propertyValue = props.getProperty(propertyName); if(propertyName.endsWith("encrypted")){ System.out.println("Decrypting the property " + propertyName); String convertedValue = decrypt(propertyValue); System.out.println("Decrypted the property value to " + convertedValue); if (!ObjectUtils.nullSafeEquals(propertyValue, convertedValue)) { props.setProperty(propertyName, convertedValue); } } } } } Update: Forget my custom placeholder configurer, even the spring provided one has trouble if I replace with this <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:my.propeties"/> </bean> What is context:property-placholder doing that the bean definition can't?

  • Sonar Analysis crashing with default configuration in Maven

    - by Robert Mandeville
    I'm starting to experiment with Sonar, and having trouble. I'm running everything on the same Red Hat Linux server, against Java 1.6.10. I launched the server with "bin/linux-x86-32" (the JVM is 32-bit). The sonar.log shows no SEVERE or ERROR and one WARNING, that I'm using the default Derby database (I'll fix that once I get things running at all). I am trying to build a Maven project that builds a JAR. I made no Sonar-specific changes (other than one described below). I can run "mvn clean install" with no problem. However, if I then run "mvn -e sonar:sonar", I get the stacktrace listed below. The server logs no events. I added the dependency "commons-pool:commons-pool:20030825.183949, but to no avail. Any idea as to what I'm doing wrong? [INFO] Error stacktraces are turned on. [INFO] Scanning for projects...

  • HSDPA modem only working on certain USB ports

    - by nabulke
    Depending on which USB port I use to connect my HSDPA modem, the network manager will connect to the internet or not. I used to work (i.e. established a internet connection automatically) on all ports, but over time it simply stopped on some ports. lsusb output in all cases looks like that (Device ID varies depending on USB port): Bus 001 Device 009: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem Any ideas what could cause this behaviour? What can I do to fix this?

  • Microsoft, jQuery, and Templating

    - by Stephen Walther
    About two months ago, John Resig and I met at Café Algiers in Harvard square to discuss how Microsoft can contribute to the jQuery project. Today, Scott Guthrie announced in his second-day MIX keynote that Microsoft is throwing its weight behind jQuery and making it the primary way to develop client-side Ajax applications using Microsoft technologies. What does this announcement mean? It means that Microsoft is shifting its resources to invest in jQuery. Developers on the ASP.NET team are now working full-time to contribute features to the core jQuery library. Furthermore, we are working with other teams at Microsoft to ensure that our technologies work great with jQuery. We are contributing to the open-source jQuery project in the exact same way that any other company or individual from the community can contribute to jQuery. We are writing proposals, submitting the proposals to the jQuery forums, and revising the proposals in response to community feedback. The jQuery team can decide to reject or accept any feature that we propose. Any feature that Microsoft contributes to jQuery will be platform neutral. In other words, Microsoft contributions will benefit PHP and RAILS developers just as much as they benefit ASP.NET developers. Microsoft contributions to jQuery will improve the web for everyone. Contributing Support for Templates to jQuery Core Our first proposal concerns templating. We want to contribute support for templates to jQuery so that JavaScript developers can use jQuery to easily display a set of database records. You can read our templating proposal here: http://wiki.github.com/nje/jquery/jquery-templates-proposal You can download and play with our prototype for templating here: http://github.com/nje/jquery-tmpl The following code illustrates how you can use a template to display a set of products in a bulleted list: <script type="text/javascript"> jQuery(function(){ var products = [ { name: "Product 1", price: 12.99}, { name: "Product 2", price: 9.99}, { name: "Product 3", price: 35.59} ]; $("ul").append("#template", products); }); </script> <script id="template" type="text/html"> <li>{%= name %} - {%= price %}</li> </script> <ul></ul> The template is contained in a SCRIPT element that has a TYPE=”text/html” attribute. Browsers ignore the contents of a SCRIPT element when they don’t understand the content type. Notice that the placeholder {%=...%} is used within the template to indicate where the name and price of a product should appear. The delimiters {%=…%} are used for expressions and the delimiters {%...%} are used for code. Finally, the products are rendered using the template with the call to $(“ul”).append(“#template”, products). The standard jQuery DOM manipulation methods have been modified to support templates. When the page above is rendered, you get the bulleted list displayed in the following figure. Our goal is to keep our proposal for templates as simple as possible. After support for templating has been added to jQuery, plug-in authors can take advantage of templating when building complex data-driven plug-ins such as a DataGrid plug-in. The Ajax Control Toolkit Over 100,000 developers download the Ajax Control Toolkit every month. That’s a mind-boggling number of downloads. We realize that the Ajax Control Toolkit is extremely popular among ASP.NET Web Forms developers and we want to continue to invest in the Ajax Control Toolkit. If you are adding JavaScript interactivity to an ASP.NET Web Forms application, and you don’t want to write JavaScript, then we recommend that you use the server controls in the Ajax Control Toolkit. Using the Ajax Control Toolkit does not require knowledge of JavaScript and the toolkit enables you to build applications with the concepts familiar to ASP.NET Web Forms applications developers. If, however, you are interested in creating client-side interactivity without server controls then we recommend that you use jQuery. We plan to continue to release new versions of the Ajax Control Toolkit every few months. Our goal is to continue to improve the quality of the Ajax Control Toolkit and to make it easier for the community to contribute code, bug fixes, and documentation. The ASP.NET Ajax Library We are moving the ASP.NET Ajax Library into the Ajax Control Toolkit. If you currently use ASP.NET Ajax Library client templates, client data-binding, or the client script loader then you can continue to use these features by downloading the Ajax Control Toolkit. Be aware that our focus with the Ajax Control Toolkit is server-side Ajax.  For client-side Ajax, we are shifting our focus to jQuery. For example, if you have been using ASP.NET Ajax Library client templates then we recommend that you shift to using jQuery instead. Conclusion Our plan is to focus on jQuery as the primary technology for building client-side Ajax applications moving forward. We want to adapt Microsoft technologies to work great with jQuery and we want to contribute features to jQuery that will make the web better for everyone. We are very excited to be working with the jQuery core team.

  • F# for the C# Programmer

    - by mbcrump
    Are you a C# Programmer and can’t make it past a day without seeing or hearing someone mention F#?  Today, I’m going to walk you through your first F# application and give you a brief introduction to the language. Sit back this will only take about 20 minutes. Introduction Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution . In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it is now will now be shipped as one of the core languages in Visual Studio 2010 , alongside C++, C# 4.0 and VB. The F# programming language incorporates many state-of-the-art features from programming language research and ossifies them in an industrial strength implementation that promises to revolutionize interactive, parallel and concurrent programming. Advantages of F# F# is the world's first language to combine all of the following features: Type inference: types are inferred by the compiler and generic definitions are created automatically. Algebraic data types: a succinct way to represent trees. Pattern matching: a comprehensible and efficient way to dissect data structures. Active patterns: pattern matching over foreign data structures. Interactive sessions: as easy to use as Python and Mathematica. High performance JIT compilation to native code: as fast as C#. Rich data structures: lists and arrays built into the language with syntactic support. Functional programming: first-class functions and tail calls. Expressive static type system: finds bugs during compilation and provides machine-verified documentation. Sequence expressions: interrogate huge data sets efficiently. Asynchronous workflows: syntactic support for monadic style concurrent programming with cancellations. Industrial-strength IDE support: multithreaded debugging, and graphical throwback of inferred types and documentation. Commerce friendly design and a viable commercial market. Lets try a short program in C# then F# to understand the differences. Using C#: Create a variable and output the value to the console window: Sample Program. using System;   namespace ConsoleApplication9 {     class Program     {         static void Main(string[] args)         {             var a = 2;             Console.WriteLine(a);             Console.ReadLine();         }     } } A breeze right? 14 Lines of code. We could have condensed it a bit by removing the “using” statment and tossing the namespace. But this is the typical C# program. Using F#: Create a variable and output the value to the console window: To start, open Visual Studio 2010 or Visual Studio 2008. Note: If using VS2008, then please download the SDK first before getting started. If you are using VS2010 then you are already setup and ready to go. So, click File-> New Project –> Other Languages –> Visual F# –> Windows –> F# Application. You will get the screen below. Go ahead and enter a name and click OK. Now, you will notice that the Solution Explorer contains the following: Double click the Program.fs and enter the following information. Hit F5 and it should run successfully. Sample Program. open System let a = 2        Console.WriteLine a As Shown below: Hmm, what? F# did the same thing in 3 lines of code. Show me the interactive evaluation that I keep hearing about. The F# development environment for Visual Studio 2010 provides two different modes of execution for F# code: Batch compilation to a .NET executable or DLL. (This was accomplished above). Interactive evaluation. (Demo is below) The interactive session provides a > prompt, requires a double semicolon ;; identifier at the end of a code snippet to force evaluation, and returns the names (if any) and types of resulting definitions and values. To access the F# prompt, in VS2010 Goto View –> Other Window then F# Interactive. Once you have the interactive window type in the following expression: 2+3;; as shown in the screenshot below: I hope this guide helps you get started with the language, please check out the following books for further information. F# Books for further reading   Foundations of F# Author: Robert Pickering An introduction to functional programming with F#. Including many samples, this book walks through the features of the F# language and libraries, and covers many of the .NET Framework features which can be leveraged with F#.       Functional Programming for the Real World: With Examples in F# and C# Authors: Tomas Petricek and Jon Skeet An introduction to functional programming for existing C# developers written by Tomas Petricek and Jon Skeet. This book explains the core principles using both C# and F#, shows how to use functional ideas when designing .NET applications and presents practical examples such as design of domain specific language, development of multi-core applications and programming of reactive applications.

  • Fusion HCM SaaS – Integration

    - by Kiran Mundy
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Fusion HCM SaaS – Integration A typical implementation pattern we’re seeing with Fusion Apps early adopters is implementing a few Fusion HCM applications that bring the most benefit to their company with the least disruption to existing programs and interfaces. Very often this ends up being Fusion Goals & Performance, Talent, Compensation or Benefits, often with Taleo for recruiting. The implementation picture looks like what you see below: Here, you can see that all the “downstream integrations” from the On-Premise Core HR, are unaffected because the master for employee data is still your On-Premise Core HR system – all updates and new hires are made here (although they may be fed in from Taleo to start with). As a second phase when customers migrate Core HR to Fusion HCM, they have to come up with a strategy to manage integrations to all their downstream applications that require employee details. For customers coming from EBS HR, a short term strategy that allows for minimal impact, is to extract employee data from Fusion (Via HCM Extract), and load the shared EBS HR tables (which are part of an EBS Financials install anyways), and let your downstream integrations continue to function based on this data as shown below. If you are not coming from EBS HR and there are license implications, you may want to consider: Creating an On-Premise warehouse for extracting data from Fusion Apps. Leveraging Fusion Apps Web Services (available to SaaS customers starting R7) to directly retrieve/write data to Fusion Apps. Integration Tools File Based Loader This is the primary mechanism for loading HCM data (both initial load and incremental updates) into Fusion HCM. Employee & related data can be uploaded into Fusion HCM using File Based Loader. Note that ability to schedule File Based Loader to run on a pre-defined schedule will be available as a patch on top of Rel 5. Hr2Hr has been deprecated in favor of File Based Loader, but for existing customers using Hr2Hr, here are some sample scripts that show how to get more informative error messages. They can be run by creating data model sql queries in BI Publisher. The scripts currently have hard coded values for request id and loader batch id, which your developer will need to update to the correct values for you. The BI Publisher Training Session recorded on Apr 18th is available here (under "Recordings"). This will enable a somewhat technical resource to create a data model sql query. Links to Documentation & Traning Reference documentation for File Based Loader on docs.oracle.com FBL 1.1 MOS Doc Id 1533860.1 Sample demo data files for File Based Loader HCM SaaS Integrations ppt and recording. EBS api's Loading Information into EBS Full or Shared HCM This could be candidate information being loaded from Taleo into EBS or  Employee information being loaded from Fusion HCM into an EBS shared HR install (for downstream applications & EBS Financials).

  • Searching for the Perfect Developer&rsquo;s Laptop.

    - by mbcrump
    I have been in the market for a new computer for several months. I set out with a budget of around $1200. I knew up front that the machine would be used for developing applications and maybe some light gaming. I kept switching between buying a laptop or a desktop but the laptop won because: With a Laptop, I can carry it everywhere and with a desktop I can’t. I searched for about 2 weeks and narrowed it down to a list of must-have’s : i7 Processor (I wasn’t going to settle for an i5 or AMD. I wanted a true Quad-core machine, not 2 dual-core fused together). 15.6” monitor SSD 128GB or Larger. – It’s almost 2011 and I don’t want an old standard HDD in this machine. 8GB of DDR3 Ram. – The more the better, right? 1GB Video Card (Prefer NVidia) – I might want to play games with this. HDMI Port – Almost a standard on new Machines. This would be used when I am on the road and want to stream Netflix to the HDTV in the Hotel room. Webcam Built-in – This would be to video chat with the wife and kids if I am on the road. 6-Cell Battery. – I’ve read that an i7 in a laptop really kills the battery. A 6-cell or 9-cell is even better. That is a pretty long list for a budget of around $1200. I searched around the internet and could not buy this machine prebuilt for under $1200. That was even with coupons and my company’s 10% Dell discount. The only way that I would get a machine like this was to buy a prebuilt and replace parts. I chose the  Lenovo Y560 on Newegg to start as my base. Below is a top-down picture of it.   Part 1: The Hardware The Specs for this machine: Color :  GrayOperating System : Windows 7 Home Premium 64-bitCPU Type : Intel Core i7-740QM(1.73GHz)Screen : 15.6" WXGAMemory Size : 4GB DDR3Hard Disk : 500GBOptical Drive : DVD±R/RWGraphics Card : ATI Mobility Radeon HD 5730Video Memory : 1GBCommunication : Gigabit LAN and WLANCard slot : 1 x Express Card/34Battery Life : Up to 3.5 hoursDimensions : 15.20" x 10.00" x 0.80" - 1.30"Weight : 5.95 lbs. This computer met most of the requirements above except that it didn’t come with an SSD or have 8GB of DDR3 Memory. So, I needed to start shopping except this time for an SSD. I asked around on twitter and other hardware forums and everyone pointed me to the Crucial C300 SSD. After checking prices of the drive, it was going to cost an extra $275 bucks and I was going from a spacious 500GB drive to 128GB. After watching some of the SSD videos on YouTube I started feeling better. Below is a pic of the Crucial C300 SSD. The second thing that I needed to upgrade was the RAM. It came with 4GB of DDR3 RAM, but it was slow. I decided to buy the Crucial 8GB (4GB x 2) Kit from Newegg. This RAM cost an extra $120 and had a CAS Latency of 7. In the end this machine delivered everything that I wanted and it cost around $1300. You are probably saying, well your budget was $1200. I have spare parts that I’m planning on selling on eBay or Anandtech.  =) If you are interested then shoot me an email and I will give you a great deal mbcrump[at]gmail[dot]com. 500GB Laptop 7200RPM HDD 4GB of DDR3 RAM (2GB x 2) faceVision HD 720p Camera – Unopened In the end my Windows Experience Rating of the SSD was 7.7 and the CPU 7.1. The max that you can get is a 7.9. Part 2: The Software I’m very lucky that I get a lot of software for free. When choosing a laptop, the OS really doesn’t matter because I would never keep the bloatware pre-installed or Windows 7 Home Premium on my main development machine. Matter of fact, as soon as I got the laptop, I immediately took out the old HDD without booting into it. After I got the SSD into the machine, I installed Windows 7 Ultimate 64-Bit. The BIOS was out of date, so I updated that to the latest version and started downloading drivers off of Lenovo’s site. I had to download the Wireless Networking Drivers to a USB-Key before I could get my machine on my wireless network. I also discovered that if the date on your computer is off then you cannot join the Windows 7 Homegroup until you fix it. I’m aware that most people like peeking into what programs other software developers use and I went ahead and listed my “essentials” of a fresh build. I am a big Silverlight guy, so naturally some of the software listed below is specific to Silverlight. You should also check out my master list of Tools and Utilities for the .NET Developer. See a killer app that I’m missing? Feel free to leave it in the comments below. My Software Essential List.

  • dpkg unsatisfied dependencies, now apt-get wants to remove whole system

    - by Bruno Finger
    firstly, I'm sorry for my terminal output in portuguese, but I guess it is still understandable. I am using Ubuntu GNOME 14.04 and I tried to update the GNOME Online Accounts packages by downloading the following .deb files from packages.ubuntu.com for the Ubuntu 14.10 version: libgoa-backend-1.0-dev_3.12.4-1_amd64.deb libgoa-backend-1.0-1_3.12.4-1_amd64.deb libgoa-1.0-dev_3.12.4-1_amd64.deb libgoa-1.0-0b_3.12.4-1_amd64.deb gnome-online-accounts_3.12.4-1_amd64.deb gir1.2-goa-1.0_3.12.4-1_amd64.deb After downloading them in the same folder, I run the command sudo dpkg -i *.deb, but it didn't install the packages, instead it showed errors due to packages which them depend doesn't meet the required version (and Ubuntu have no way to install them since they are not in this version's repositories). So now every time I want to install anything through apt-get, Ubuntu tells me to run apt-get -f install to fix the errors.

  • Five Things Learned at the BSR Conference in San Francisco on Nov 2nd-4th

    - by Evelyn Neumayr
    The BSR Conference 2011—“Redefining Leadership”—held from Nov 2nd to Nov 4th in San Francisco, with Oracle as one of the main sponsors, saw senior business executives, civil society representatives, and other experts from around the world gathering to share strategies and insights on the future of sustainability. The general conference sessions kicked off on November 2nd with a plenary address by former U.S. Vice President Al Gore. Other sessions were presented by CEOs of the caliber of Carl Bass (Autodesk), Brian Dunn (Best Buy), Carlos Brito (Anheuser-Busch InBev) and Ofra Strauss (Strauss Group). Here are five key highlights from the conference: 1.      The main leadership challenge is integrating sustainability into core business functions and overcoming short-termism. The “BSR GlobeScan State of Sustainable Business Poll 2011” - a survey of nearly 500 business leaders from 300 member companies - shows that 84% of respondents are optimistic that global businesses will embrace CSR/sustainability as part of their core strategies and operations in the next five years but consider integrating sustainability into their core business functions the key challenge. It is still difficult for many companies that are committed to the sustainability agenda to find investors that understand the long-term implications and as Al Gore said “Many companies are given the signal by the investors that it is the short term results that matter and that is a terribly debilitating force in the market.” 2.      Companies are required to address increasing compliance requirements and transparency in their supply chain, especially in relation with conflict minerals legislation and water management. The Dodd-Frank legislation, OECD guidelines, and the upcoming Securities and Exchange Commission (SEC) rules require companies to monitor upstream the sourcing of tin, tantalum, tungsten, and gold, but given the complexity of this issue companies need to collaborate and partner with peer companies in their industry as well as in other industries to understand how to address conflict minerals in their supply chains. The Institute of Public and Environmental Affairs’ (IPE) China Water Pollution Map enables the public to access thousands of environmental quality, discharge, and infraction records released by various government agencies. Empowered with this information, the public has the opportunity to place greater pressure on polluting companies to comply with environmental standards and create solutions to improve their performance. 3.      A new standard for reporting on supply chain greenhouse gas emissions is available. The New “Scope 3” Supply Chain Greenhouse Gas Inventory Standard, released on October 4th 2011, is the only international greenhouse gas emissions standard that accounts for the full lifecycle of a company’s products. It provides a framework for companies to account for indirect emissions outside of energy use, such as transportation, manufacturing, and distribution, and it incorporates both upstream and downstream impacts of a product. With key investors now listing supplier vulnerability to rising energy prices and disruptions of service as a key concern, greenhouse gas (GHG) management isn’t just for leading companies but a necessity for any business. 4.      Environmental, social, and corporate governance (ESG) reporting is becoming increasingly important to investors and other stakeholders. While European investors have traditionally driven the ESG agenda, U.S. investors are increasingly including ESG data in their analyses. This trend will likely increase as stakeholders continue to demand that an ESG lens be applied to their investments. Investors are increasingly looking to partner on sustainability, as they see the benefits of ESG providing significant returns on investment. 5.      Software companies are offering an increasing variety of solutions to help drive changes and measure performance internally, in supply chains, and across peer companies. The significant challenge is how to integrate different software systems to facilitate decision-making based on a holistic understanding of trade-offs. Jon Chorley, Chief Sustainability Officer and Vice President, Supply Chain Management Product Strategy at Oracle was a panelist in the “Trends in Sustainability Software” session and commented that, “How we think about our business decisions really comes down to how we think about cost. And as long as we don’t assign a cost to things that have an environmental impact or social impact, then we make decisions based on incomplete information. If we could include that in the process that determines ‘Is this product profitable? we would then have a much better decision.” For more information on BSR visit www.brs.org.

  • Thoughts on my new template language/HTML generator?

    - by Ralph
    I guess I should have pre-faced this with: Yes, I know there is no need for a new templating language, but I want to make a new one anyway, because I'm a fool. That aside, how can I improve my language: Let's start with an example: using "html5" using "extratags" html { head { title "Ordering Notice" jsinclude "jquery.js" } body { h1 "Ordering Notice" p "Dear @name," p "Thanks for placing your order with @company. It's scheduled to ship on {@ship_date|dateformat}." p "Here are the items you've ordered:" table { tr { th "name" th "price" } for(@item in @item_list) { tr { td @item.name td @item.price } } } if(@ordered_warranty) p "Your warranty information will be included in the packaging." p(class="footer") { "Sincerely," br @company } } } The "using" keyword indicates which tags to use. "html5" might include all the html5 standard tags, but your tags names wouldn't have to be based on their HTML counter-parts at all if you didn't want to. The "extratags" library for example might add an extra tag, called "jsinclude" which gets replaced with something like <script type="text/javascript" src="@content"></script> Tags can be optionally be followed by an opening brace. They will automatically be closed at the closing brace. If no brace is used, they will be closed after taking one element. Variables are prefixed with the @ symbol. They may be used inside double-quoted strings. I think I'll use single-quotes to indicate "no variable substitution" like PHP does. Filter functions can be applied to variables like @variable|filter. Arguments can be passed to the filter @variable|filter:@arg1,arg2="y" Attributes can be passed to tags by including them in (), like p(class="classname"). You will also be able to include partial templates like: for(@item in @item_list) include("item_partial", item=@item) Something like that I'm thinking. The first argument will be the name of the template file, and subsequent ones will be named arguments where @item gets the variable name "item" inside that template. I also want to have a collection version like RoR has, so you don't even have to write the loop. Thoughts on this and exact syntax would be helpful :) Some questions: Which symbol should I use to prefix variables? @ (like Razor), $ (like PHP), or something else? Should the @ symbol be necessary in "for" and "if" statements? It's kind of implied that those are variables. Tags and controls (like if,for) presently have the exact same syntax. Should I do something to differentiate the two? If so, what? This would make it more clear that the "tag" isn't behaving like just a normal tag that will get replaced with content, but controls the flow. Also, it would allow name-reuse. Do you like the attribute syntax? (round brackets) How should I do template inheritance/layouts? In Django, the first line of the file has to include the layout file, and then you delimit blocks of code which get stuffed into that layout. In CakePHP, it's kind of backwards, you specify the layout in the controller.view function, the layout gets a special $content_for_layout variable, and then the entire template gets stuffed into that, and you don't need to delimit any blocks of code. I guess Django's is a little more powerful because you can have multiple code blocks, but it makes your templates more verbose... trying to decide what approach to take Filtered variables inside quotes: "xxx {@var|filter} yyy" "xxx @{var|filter} yyy" "xxx @var|filter yyy" i.e, @ inside, @ outside, or no braces at all. I think no-braces might cause problems, especially when you try adding arguments, like @var|filter:arg="x", then the quotes would get confused. But perhaps a braceless version could work for when there are no quotes...? Still, which option for braces, first or second? I think the first one might be better because then we're consistent... the @ is always nudged up against the variable. I'll add more questions in a few minutes, once I get some feedback.
