• HP Compaq T20 Thin Clients & Windows Server 2008 R2: RDP Disconnects instantly.

  - by sinni800

  Hello, I have some HP Compaq T20 Thin Clients connecting to a Windows Server 2003. Now I want to upgrade to 2008 R2, so I tested a trial installation with remote desktop in administration mode. So I try to connect my T20 to the server and... It doesn't matter if I turn off encryption or not it disconnects with an generic error instantly. The T20s have Windows CE embedded with RDP 5.2 installed. Out of curiosity I tried Windows Server 2008 (no R2) and it worked! I tried the same with a Windows 7 machine set up with- no work. I can not update the T20s to Windows NT embedded for example because they only have a low amount of flash memory. It seems the "new" version of RDP coming from Windows 7 / Windows Server 2008 R2 is completely incompatible with the older 5.2 version. People are having the same problem here: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/700488cd-a872-47e5-85a7-595f050afc10

• wget works with company proxy but apt-get and dpkg doesn't

  - by damian

  Hi, I am trying to install some software in a fresh install of Linux dnoseda 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux. I already set the variables http_proxy, https_proxy and ftp_proxy and wget works perfectly. But when I try with apt-get it blocks trying to conect directly to the site, without the proxy. Or the other behavior that I got is a lots of 407 authentication errors. But the wget of those packages works perfectly. It's something missing? Can you help me? thanks in advance.

• Project setup for creating third party libraries for Android

  - by Jarle Hansen

  Hi all, I am creating a library for Android that others can include in their own project. So far I have been working on it as a normal Java project with JDK 1.6 setup as system library. This works just fine in Eclipse when I add the android.jar. The issue comes when I try to my build script. I am running Gradle and doing a normal compile and test build cycle. My thoughts were that it does not matter if I compile it with a normal JDK, since this is not a standalone application. The benefits by creating a normal Java project is that Gradle does support this much better. My project also does not contain any UI at all. However, the problem is that of course android.jar and the JDK contains lots of the same classes and I think that this is what messes up my build script. Everything crashes when running the tests (the tests are in the same project under src/test/java). My question is, how should I create this project that is meant to be included in Android projects as a third party library? Should I create it as an Android project in Eclipse even though I am only creating a library that does not use any of the UI features? Also, should the tests be in a separate project? Thanks for all responses!

• Testing a method that sends e-mail without sending the mail

  - by SnOrfus

  I have a method like public abstract class Base { public void MethodUnderTest(); } public class ClassUnderTest : Base { public override MethodUnderTest() { if(condition) { IMail mail = new Mail() { /* ... */ }; IMailer mailer = new Mailer() { /* ... */ } mailer.Send(mail); } else { /* ... */ } } } I have unit tests for this method, and the mail gets sent to myself, so it's not terrible (better than no test) but I'd prefer not to send the mail. The problem I have is that I don't want test specific code in the class (ie. if (testMode) return; instead of sending the mail) I don't know lots about DI, but I considered passing a mock IMailer into MethodUnderTest except that it overrides the base class, and no other class that derives from Base needs an IMailer object (I don't want to force implementers of Base to take an unnecessary IMailer in MethodUnderTest) What else can I do? (note: IMail and IMailer are part of an external library for sending e-mail. It's written in house, so I can modify it all I like if necessary, though I can't see a need to in this situation)

• Trying to use a authlogic-connect as a plugin in place of gem - Server doesn't start

  - by Arkid

  I am trying to use Authlogic-connect as a plugin in Rails 3 in place of a gem. I have made an entry in the gemfile as gem "authlogic-connect", :require => "authlogic-connect", :path => "localgems" Now when I run the bundle install, it runs fine. When I try to start the server i get the error Could not find gem 'authlogic-connect (>= 0, runtime)' in source at localgems. Source does not contain any versions of 'authlogic-connect (>= 0, runtime)' Try running `bundle install`. I have placed the unzipped Gem renamed as authlogic-connect in the localgems folder. what is the problem? Here is what I get on using rails plugin install arkidmitra$ rails plugin install git://github.com/viatropos/authlogic-connect.git Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -q, [--quiet] # Supress status output -s, [--skip] # Skip files that already exist -f, [--force] # Overwrite files that already exist -p, [--pretend] # Run but do not make any changes Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.

• php/mongodb: how does references work in php?

  - by harald

  hello, i asked this in the mongodb user-group, but was not satisfied with the answer, so -- maybe someone at stackoverflow can enlighten me: the question was: $b = array('x' => 1); $ref = &$b; $collection->insert($ref); var_dump($ref); $ref does not contain '_id', because it's a reference to $b, the handbook states. (the code snippet is taken from the php mongo documentation) i should add, that: $b = array('x' => 1); $ref = $b; $collection->insert($ref); var_dump($ref); in this case $ref contains the _id -- for those, who do not know, what the insert method of mongodb-php-driver does -- because $ref is passed by reference (note the $b with and without referencing '&'). on the other hand ... function test(&$data) { $data['_id'] = time(); } $b = array('x' => 1); $ref =& $b; test($ref); var_dump($ref); $ref contains _id, when i call a userland function. my question is: how does the references in these cases differ? my question is probably not mongodb specific -- i thought i would know how references in php work, but apparently i do not: the answer in the mongodb user-group was, that this was the way, how references in php work. so ... how do they work -- explained with these two code-snippets? thanks in advance!!!

• Should Development / Testing / QA / Staging environments be similar?

  - by Walter White

  Hi all, After much time and effort, we're finally using maven to manage our application lifecycle for development. We still unfortunately use ANT to build an EAR before deploying to Test / QA / Staging. My question is, while we made that leap forward, developers are still free to do as they please for testing their code. One issue that we have is half our team is using Tomcat to test on and the other half is using Jetty. I prefer Jetty slightly over Tomcat, but regardless we using WAS for all the other environments. My question is, should we develop on the same application server we're deploying to? We've had numerous bugs come up from these differences in environments. Tomcat, Jetty, and WAS are different under the hood. My opinion is that we all should develop on what we're deploying to production with so we don't have the problem of well, it worked fine on my machine. While I prefer Jetty, I just assume we all work on the same environment even if it means deploying to WAS which is slow and cumbersome. What are your team dynamics like? Our lead developers stepped down from the team and development has been a free for all since then. Walter

• How to pass PHP variable as FlashVars via SWFObject

  - by Matt

  I am trying to take a PHP variable and pass it along to Flash via Flash vars. My end goal is to pass a string formatted as XML to Flash, but because I'm struggling I've stripped everything down to the basics. I'm just trying to pass a simple PHP string variable to Flash via FlashVars with SWFObject but something isn't right. The page won't load when I try to pass the variable inside of php tags, but it will load if I just pass a hard coded string. The basic structure of my page is that I have some PHP declared at the top like so: PHP <?php $test = "WTF"; ?> Some HTML (excluded here for simplicity sake) and then the JavaScript SWFObject Embed within my HTML: <script type="text/javascript" src="js/swfobject2.js"></script> <script type="text/javascript"> // <![CDATA[ var swfURL = "swfs/Init-Flash-PHP.swf"; var flashvars = {}; flashvars.theXML = <?php print $test ?>; var params = {}; //params.menu = "false"; params.scale = "showAll"; params.bgcolor = "#000000"; params.salign = "TL"; //params.wmode = "transparent"; params.allowFullScreen = "true"; params.allowScriptAccess = "always"; var attributes = {}; attributes.id = "container"; attributes.name = "container"; swfobject.embedSWF(swfURL, "container", '100%', '100%', "9.0.246", "elements/swfs/expressinstall.swf", flashvars, params, attributes); // ]]> </script> And the bare essentials of the ActionScript 3 Code: _paramObj = LoaderInfo(stage.loaderInfo).parameters; theText_txt.text = _paramObj['theXML']; How do I pass a PHP variable using SWFObject and FlashVars? Thanks.

• Algorithm to match list of regular expressions

  - by DSII

  I have two algorithmic questions for a project I am working on. I have thought about these, and have some suspicions, but I would love to hear the community's input as well. Suppose I have a string, and a list of N regular expressions (actually they are wildcard patterns representing a subset of full regex functionality). I want to know whether the string matches at least one of the regular expressions in the list. Is there a data structure that can allow me to match the string against the list of regular expressions in sublinear (presumably logarithmic) time? This is an extension of the previous problem. Suppose I have the same situation: a string and a list of N regular expressions, only now each of the regular expressions is paired with an offset within the string at which the match must begin (or, if you prefer, each of the regular expressions must match a substring of the given string beginning at the given offset). To give an example, suppose I had the string: This is a test string and the regex patterns and offsets: (a) his.* at offset 0 (b) his.* at offset 1 The algorithm should return true. Although regex (a) does not match the string beginning at offset 0, regex (b) does match the substring beginning at offset 1 ("his is a test string"). Is there a data structure that can allow me to solve this problem in sublinear time? One possibly useful piece of information is that often, many of the offsets in the list of regular expressions are the same (i.e. often we are matching the substring at offset X many times). This may be useful to leverage the solution to problem #1 above. Thank you very much in advance for any suggestions you may have!

• ForeignSecurityPrincipals with LDAP connection on Active Directory servers with trusted forest

  - by Killerwhile

  The context is the following : Two domains mutually trusted dc=dom1 dc=dom2 a group cn=group1,ou=someou,dc=dom1 with users inside : cn=user11,ou=anotherou,dc=dom1 cn=user12,ou=anotherou,dc=dom1 cn=user13,ou=anotherou,dc=dom1 cn=user21,ou=anotherou,dc=dom2 cn=user22,ou=anotherou,dc=dom2 cn=user23,ou=anotherou,dc=dom2 The questions : 1. Test user's credentials How can I do a ldap bind to test credentials for users of dom2 ? I tried to bind as usual but I cannot authenticate users of dom2, even if I connect in ldaps. Is there any trick ? Special permissions to set ? 2. Search and display users from the group. How can I retrieve the detailed informations about the users of dom1 and dom2 using LDAP(s) connection on the AD of dom1 ? I have an technical user which has right to browse both domain. I'm able to see 6 entries in the group with the following filter : (&(memberOf=cn=group1,ou=someou,dc=dom1)(|(objectClass=user)(objectClass=foreignSecurityPrincipal))) but the users from the other domain are seen as cn=...(some key)...,cn=foreignSecurityPrincipal,dc=dom1 Java hints would be better. Thanks a lot !

• Rails 3 memory issue

  - by Erik

  Hello! I'm developing a new site based on Ruby on Rails 3 beta. I knew this might be a bad idea considering it's just beta, but I still thought it might work. Now though I'm having HUGE problems with Rails consuming huge ammounts of memory. For my application today it consumes about 10 mb per request and it doesn't seem to release it either. So I thought this might be because of bloat in my application and thus I created a test app just to compare. For my test app I just generated a model with a scaffold and then created about 20 records on this model. I then went to the index page and hit refresh and I could immediately see memory taking off! Less than my app but still about 1-3 mb per request. I'm working in OSX Leopard, with Ruby 1.8.7, Rails 3.0.0.beta and a SQLLite db for development. Does anyone recognize my problem? I would really appreciate some help here. :/ Thanks!

• Reference a Map by name within Velocity Template

  - by Wiretap

  Pretty sure there is an easy answer to this, but just can't find the right VTL syntax. In my context I'm passing a Map which contains other Maps. I'd like to reference these inner maps by name and assign them within my template. The inner maps are constructed by different parts of the app, and then added to the context by way of example public static void main( String[] args ) throws Exception { VelocityEngine ve = new VelocityEngine(); ve.init(); Template t = ve.getTemplate( "test.vm" ); VelocityContext context = new VelocityContext(); Map<String,Map<String,String>> messageData = new HashMap<String, Map<String,String>>(); Map<String,String> data_map = new HashMap<String,String>(); data_map.put("data_1","1234"); data_map.put("a_date", "31-Dec-2009"); messageData.put("inner_map", data_map); context.put("msgData", messageData); StringWriter writer = new StringWriter(); t.merge( context, writer ); System.out.println( writer.toString() ); } Template - test.vm #set ($in_map = $msgData.get($inner_map) ) data: $in_map.data_1 $in_map.a_date

• Sonicwall settings for Polycom TFTP

  - by Michael Glenn

  I'm switching our VoIP phones (Polycom 301s and 501s) to our data network. They were previously segmented to their own network. This means disabling the DHCP on the Trixbox (Asterisk) server and configuring the Sonicwall TZ 210 DHCP to indicate that Trixbox is the TFTP server. The Polycom phones are stating "could not contact boot server". All phones are configured to TFTP and were confirmed working when previously using the Trixbox server for DHCP. Trixbox DHCP is now turned off. I've configured options 66(as String), 128(as IP) and 150(as IP) in DHCP and added them to a TFTP Option Group. I've enabled "Allow BOOTP Clients to use Range" for the Dynamic IP range and assigned the Option Group TFTP as the DHCP Generic Option Group. Any idea what I'm missing? Is there a separate tool to inspect the DHCP response to compare Trixbox to the Sonicwall?

• Substitute drivers for a 32 bit printer on a 64 bit OS

  - by Derek G

  I'm trying to use an old GCC Elite 12N B&W laser printer for printing schoolwork and other miscellany on 64 bit Windows 7. The only drivers available are 32 bit. As far as I know, it's not possible to use 32 bit drivers on a 64 bit OS, but is there some sort of generic Postscript driver I could substitute? If the drivers are, in fact, compatible, could someone suggest a way to modify the INF file so that Windows will recognize it? Thanks for your help!

• MonoDevelop 2.8.2: Build failed. Illegal characters in path

  - by user1056607

  I have just installed MonoDevelop 2.8.2. After opening a new solution named test I attempted to run the project. I push f5 and all I see is a "Build failed. Illegal characters in path" error in the bottom left. I open up the Error List and see no errors. I have done some searching and only find solutions pertaining to projects that are beyond the scope of just the pre-generated code. This is the code: using System; namespace Test { class MainClass { public static void Main(string[] args) { Console.WriteLine("Hello World!"); } } } I have tried to uninstall/reinstall, cut out any spaces in the path to the program or the solution, and even opened VS2010 and just copy pasted that code over. I've looked over my options under tools, solution options under project, and the project's options. I am running MD 2.8.2 with GTK# and Microsoft's .NET runtime. Let me know if you need anymore information. Any help would be appreciated. Thank you for your time!

• Java Robot key activity seems to stop working while certain software is running

  - by Mike Turley

  I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

• Website (jQuery) consistently crashes Internet Explorer (REALLY STUCK!)

  - by Bradley Bell

  Hey Guys. I posted this question yesterday, but haven't had a response. Basically, I'm totally stuck and clueless over crashing in Internet Explorer. The website now works fine in all browsers except internet explorer. The website is heavily reliant on jQuery and as far as I'm aware, I cant spot anything wrong with the script. Internet Explorer displays no errors and I don't know what I can possibly change. It displays fine, which would suggest that its nothing up with the CSS or HTML? I'm fairly sure it has to be the script, because it only crashes when you hover over one of the mouseover links. I'm already over the deadline and time is ticking! Its driving me crazy. I've uploaded it onto a test directory here: www.openyourheart.org.uk/test/index.html (I'll add the script/css links below as a comment, It wont let me post more than one here!) I would reaaly, really appreciate any help on this. I can also send the website compressed and post scripts here if required/preferred. Thanks in advance, Bradley

• How does bridged networking work?

  - by agz

  How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

• In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

  - by Navi

  I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

• How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

  - by markerikson

  I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

  Because I have several builds sharing some assemblies containing common build tasks, I have one TFSBuild.proj for all builds and import different targets depending on the build, like the following: <Project DefaultTargets="DesktopBuild" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="3.5"> <Import Project="Build_1.targets" Condition="'$(BuildDefinition)'=='Build_1'" /> <Import Project="Build_2.targets" Condition="'$(BuildDefinition)'=='Build_2'" /> <Import Project="Build_3.targets" Condition="'$(BuildDefinition)'=='Build_3'" /> </Project> Each target for a particular build has your usual content for a build type file, but in my case, I also reference some tasks inside assemblies checked into the same folder as TFSBuild.proj in source control. I wanted to add folders to contain some test build targets, since my folder was getting a bit full and cluttered. The following illustrates what I mean. $(TFS project)\build\ TFSBuild.proj Build_1.targets ... Assembly1.dll Assembly2.dll ... Folder\ Test_target_1.targets .... When I stated my build, however, I found that Test_target_1.targets and other files in Folder were not being copied to the build directory, while TFSBuild.proj and other files in the root level, as it were, of the build type folder were being copied. This caused my test build to not be able to reference files inside Folder, causing my build to immediately fail. I realize the simplest work-around would be to get rid of Folder and move all of its contents up to the build folder, but I would really like to have Folder if at all possible. Thanks for your help in advance.

• what's the correct way to release a new website?

  - by kk

  so i've been working on a website on and off for about a year now, and i'm finally at a point where it's functional enough to test out in a sort of private beta (not ready for live release). but i never thought about the correct process for doing this and what things i need to take care of. i've never released a public website before. some of the questions/concerns i have in mind: 1) is it against my MSDN license agreement to release a website using the software? 2) how do i protect my "idea"? is it a bad idea to find random people you don't know to test out your site? can you make them digitally sign some sort of NDA? 3) i'm using some open source code - any proper way to release open source code to live production? 4) how much traffic can a place like discountasp.net handle anyway? can hosting sites generally handle large volume of traffic? any comments/suggestions regarding the proper/safe way to release a public website would be appreciated. i've been working on this for a while and never actually sat down to think about the right way to move from a personal side project to a live production website.

• Does HDMI cable "quality" actually affect transmission?

  - by TheDeeno

  I really don't want to pay a ridiculous price for a "name brand" HDMI cable if it doesn't really do anything for me. I'm just curious: now that most transmission is digital (packetized) is there such a thing as a "quality" cable? I suspect that if the cable works at all, I'm safe saying I have a quality connection. I just want to double check. Some of these reviewers complain that generic cables "create noise, lack bandwidth, can't handle X, etc". I'm skeptical of these reviews. If the logic for HDMI cables and quality can be applied to cables in general, please elaborate on that as well.
