• "Snapping" when in RDP

  - by Paul

  I am using mstsc.exe version 6.0 (Remote Desktop non-Metro version) from an XP machine and cannot get Windows 8 snapping to work. I can drag a metro app window to the left or right, but it doesn't stick, it just bounces back to full screen. The snap bars do not appear. The client PC has two monitors, each with a resolution of 1280x1024. While mstsc.exe 6.0 does have an option to use both monitors simultaneously in normal settings, I am launching it with spanning enabled: mstsc.exe /span So the effective resolution in the session is 2560x1024. Is there a trick to getting this to work over RDP?

• Why does tomcat like deleting my context.xml file?

  - by staticsan

  I'm developing a web-based Java application at work and (obviously) have to run it locally during development. I've figured out the Tomcat docs and have a suitable context.xml file in /etc/tomcat6/Catalina/localhost/ but every so often, Tomcat decides to delete it! Which means I have to put it back and restart Tomcat. Why does it do this? I have searched the Tomcat docs about it and am none the wiser. (Oh yes: it's not actually called context.xml but owners.xml as that's the HTTP path prefix for this application.) Update I've now seen Tomcat delete the file whilst Tomcat was running. I think I need to file a bug...

• Group Policy Task Schedule deployed to User Configuration not working, works when in Computer Configuration?

  - by user80130

  I added a Scheduled Task on my Windows 2008 R2 Domain Controller in the Group Policy Manager: MyDomain Policy User Configuration Preferences Control Panel Settings Scheduled Tasks Basic Task, like starting notepad, when user unlocks his workstation. This should show up in the client workstation's task scheduler, but it dosn't. No errors or anything like that. If I use the "Computer Configuration" instead of "User Configuration" the task appears, and I'm able to run the task. I've tried the gpupdate /force followed by gpresult and checked the report, but it dosn't contain the GPO Scheduled Tasks I created? (again, does show up when using "Computer Configuration".) The issue is that I have to run the application in the current users context, and only on a specific Employee OU, and thereby limit this task only to Employee Workstations and not apply the application when the same employee log on to internal servers and such. Primary domain dontroller is a Windows 2008 R2, workstations Windows 7 Enterprise. What am I doing wrong ?

• What is the best software to capture full-screen 3h programming session in Windows?

  - by Hugo S Ferreira

  Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

• Nearest PC equivalent to Mac Target Disk Mode?

  - by username

  Mac firmware has a special boot mode that allows you to offer its internal hdd to another computer as an external disk (you just connect the two machines via an IEEE 1394 cable). Only the second machine needs a functioning OS installed. Any good suggestions for something similar on the PC side of things? Block level access isn't important to me, I'd just like to be able to copy files off it. It doesn't matter to me if it uses Ethernet, IEEE 1394, or wifi - I just like having a quick way to access files on a client PC. Is there any single-purpose Linux distro specially designed to do this? It'd be nice to have something super simple, quickbooting, and small that I could install on a USB drive. I used to use Knoppix, but it's overkill as a Target Mode replacement.

• IIS7, different ports for websites but no portnumber in the browser

  - by Queensheep

  I have a windows server 2008 with IIS7 with 4 websites. In DNS I have 4 different URLs which point to the IP of the server. I configured each web site with the site bindings: website1: hostname: url1, port: 80, IP-Adresse: the adress of the server website2: hostname: url2, port: 80, IP-Adresse: the adress of the server The result is, that from the client, I can browse with all the 4 URLs to the specified web sites and everything is fine. Then I changed in IIS the port of the websites, so that website1 now uses port 8080, website2 uses port 8081, and so on. Now I have to use the browser with the url and the portnumber (like URL:8080). Is there a possibility, to configured the websites with different portnumbers but not to use the portnumbers in the browser?

• What would you do to improve the working of a small Development team?

  - by Omar Kooheji

  My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

• FTP an entire folder via the command line

  - by Chris Southam

  I'm looking so migrate some websites to a new server. I have SSH access to the current one but only FTP access to the new one. How can I via Centos and SSH copy entire folders to the new server via FTP? I can log into the new server via the built in FTP client on Centos but I'm not sure of the commands after this. I need to move the httpdocs folder from the old to the public_html folder of the new server. I'd love to do this server to server as it'll be a lot quicker than download - upload via my broadband connection. Yours, Chris

• Rails/Node.js interaction

  - by lpvn

  I and my co-worker are developing a web application with rails and node.js and we can't reach a consensus regarding a particular architectural decision. Our setup is basically a rails server working with node.js and redis, when a client makes a http request to our rails API in some cases our rails application posts the response to a redis database and then node.js transmits the response via websocket. Our disagreement occurs in the following point: my co-worker thinks that using node.js to send data to clients is somewhat business logic and should be inside the model, so in the first code he wrote he used commands of broadcast in callbacks and other places of the model, he's convinced that the models are the best place for the interaction between rails and node. I on the other hand think that using node.js belongs to the runtime realm, my take is that the broadcast commands and other node.js interactions should be in the controller and should only be used in a model if passed through a well defined interface, just like the situation when a model needs to access the current user of a session. At this point we're tired of arguing over this same thing and our discussion consists in us repeating to ourselves our same opinions over and over. Could anyone, preferably with experience in the same setup, give us an unambiguous response saying which solution is more adequate and why it is?

• Python web frameworks comparisons

  - by stupidLearner

  I recently asked a question on SO about Python web frameworks: http://stackoverflow.com/questions/4909306/python-web-frameworks-vs-java-web-frameworks-how-is-web-development-in-python-do I want to learn one just for fun but it also has to be able to help me deliver a proper working application. I am looking for a framework with lots of features, powerful, mature, with large community, good documentation, books etc. I need something that will help me be more productive in developing my app and not waste time figuring out how to do a certain thing in the framework or how to write workaround around the limitations of the framework. I was thinking one of the following: django, zope, turbogears, pylons. Off course the war is raging out there and there are other alternatives but seems Django is at the top... or is it just hype? I am interested in pros and cons of each. What was the best feature you think the framework has? What is the thing it lacks? What could have been done differently. Help me chose one to learn for starters.

• Can't deploy an ejb bean on jboss

  - by leo

  I am try to deploy a jar to an jboss server. It works on my environment. But when I deployed the same jar on another server, i kept getting an error saying that the persistence unit is already registered. There is no other bean using the same name and the same persistence unit name. I tried to restart the server and remove the tmp, work, data directory but still get the same error. here is my error: ObjectName: jboss.j2ee:service=EJB3,module=wess_jpa.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=dses_wess already registered.

• Geek Bike Ride Sao Paulo

  - by Tori Wieldt

  What do you do on sunny Saturday in Sao Paulo when you have several Java enthusiasts, street lanes closed off for bicyclists, new cool Duke jerseys, and some wonderful bike angels to provide a tour through the city? A GEEK BIKE RIDE, of course! The weekend before JavaOne Latin America, the Sao Paulo geek bike ride was held today. We had 20+ riders and a wonderful route that took us from the Bicycle Park to and through downtown. It was a 30Km ride, but our hosts were kind enough to give riders the option to take the subway for part of the trip. Thanks to our wonderful bike angels, the usual rental bike problems like rubbing brakes, dropped chains, and even a flat tire were handled with ease.  The geek bike ride wasn't just for out-of-towners. Loiane Groner, who lives in Sao Paulo said, "I love the Geek Bike Ride! The last time I was in these parts of the city, I think I was five years-old!" A good time was had by all. (My only crash of the day was riding up an escalator with my bike. Luckily, the bikers with me were so busy helping me that no pictures were taken. <phew>) Enjoy this video by Hugo Lavalle You can also view Hugo's pictures. More pictures to come on Stephen Chin's blog.  So, what city is up next?

• MIA

  - by Robert May

  So, I’ve been missing in action on this blog for quite some time.  I need to rectify that. Part of the reason I’ve been absent is because I haven’t be able to talk about what I’m working on.  A former client watches my blog rather closely, and although we accomplished many good things together, their culture is such that they really don’t like people to freely express their thoughts (you’ll note my blog posts stopped rather abruptly).  I learned some really important lessons about Agile in the last 3 years, and I think its worthwhile to talk about them.  Sometimes things worked really well, sometimes, they failed failed.  Sometimes that failure was me, sometimes it wasn’t. I understand Agile better now, and hopefully, what I have to say will guide others through this process and help others understand Agile better. One thing that I’ve learned is that MANY companies that say they are doing Agile are NOT really doing Agile.  To often, they pick the things they like and don’t follow the process long enough to know what rules they can break, and which ones they shouldn’t.  This is probably the primary reason why Agile fails. So, expect more posts, especially as I’m flying coast to coast. :)

• Per-vertex animation with VBOs: VBO per character or VBO per animation?

  - by charstar

  Goal To leverage the richness of well vetted animation tools such as Blender to do the heavy lifting for a small but rich set of animations. I am aware of additive pose blending like that from Naughty Dog and similar techniques but I would prefer to expend a little RAM/VRAM to avoid implementing a thesis-ready pose solver. I would also like to avoid implementing a key-frame + interpolation curve solver (reinventing Blender vertex groups and IPOs), if possible. Scenario Meshes are animated using either skeletons (skinned animation) or some form of morph targets (i.e. per-vertex key frames). However, in either case, the animations are known in full at load-time, that is, there is no physics, IK solving, or any other form of in-game pose solving. The number of character actions (animations) will be limited but rich (hand-animated). There may be multiple characters using a each mesh and its animations simultaneously in-game (they will likely be at different frames of the same animation at the same time). Assume color and texture coordinate buffers are static. Current Considerations Much like a non-shader-powered pose solver, create a VBO for each character and copy vertex and normal data to each VBO on each frame (VBO in STREAMING). Create one VBO for each animation where each frame (interleaved vertex and normal data) is concatenated onto the VBO. Then each character simply has a buffer pointer offset based on its current animation frame (e.g. pointer offset = (numVertices+numNormals)*frameNumber). (VBO in STATIC) Known Trade-Offs In 1 above: Each VBO would be small but there would be many VBOs and therefore lots of buffer binding and vertex copying each frame. Both client and pipeline intensive. In 2 above: There would be few VBOs therefore insignificant buffer binding and no vertex data getting jammed down the pipe each frame, but each VBO would be quite large. Are there any pitfalls to number 2 (aside from finite memory)? I've found a lot of information on what you can do, but no real best practices. Are there other considerations or methods that I am missing?

• site timing out when under heavy load

  - by naunu

  My client sends out eblasts at 8am monday/wed/friday. Between 8:15-8:45 the site becomes extremely slow and many users sessions timeout. My setup: Mediatemple VE 2gb dedicated ram (3 burst) Ubuntu 9.10 Apache2-mpm-worker PHP5.3-fcgi MySQL 5 I recently tried to remedy the problem by switching from apache2-mpm-prefork to mpm-worker, but am still having the same issues. My apache settings are: Timeout 100 KeepAlive On MaxKeepAliveRequests 100 <IfModule mpm_worker_module> StartServers 12 MinSpareThreads 25 MaxSpareThreads 96 ThreadLimit 96 ThreadsPerChild 25 MaxClients 225 MaxRequestsPerChild 0 </IfModule> The site is only getting ~10,000 page views during the 8am-9am hour, which I dont think should be stressing the server too badly. Maybe it is an error with the PHP settings, or bandwidth per unit time, or the site outgrew the server? Any suggestions would be very helpful - as you can see i've given it a good go before looking for help (installed mpm-worker). Also, can anyone suggest to me some free load testing software, or a tutorial on mod_status? Thank you

• Setup mutt to read through a threaded message and then return to the email index

  - by dat5h

  I have begun using mutt (terminal email client) recently and I have it setup very nicely and easy to use. My only gripe is that sometimes it is difficult to tell when I transition from one thread to the next. Is it possible to setup the bindings such that moving to the next-undeleted message would check if the next-undeleted message is in the same thread, and if that check is false it returns to the index or throws an error? For example, I currently have bind pager <down> next-undeleted bind pager } next-subthread Is there a more advanced function call that could perform this check? I haven't been able to find much on how to perform more complex function calls with such checks while checking out the manual. Any help would be appreciated.

• Connecting the Dots (.NET Business Connector)

  - by ssmantha

  Recently, one of my colleagues was experimenting with Reporting Server on DAX 2009, whenever he used to view a report in SQL Server Reporting Manager he was welcomed with an error: “Error during processing Ax_CompanyName report parameter. (rsReportParameterProcessingError)” The Event Log had the following entry: Dynamics Adapter LogonAs failed. Microsoft.Dynamics.Framework.BusinessConnector.Session.Exceptions.FatalSessionException at Microsoft.Dynamics.Framework.BusinessConnector.Session.DynamicsSession.HandleException(Stringmessage, Exception exception, HandleExceptionCallback callback) We later found out that this was due to incorrect Business Connector account, with my past experience I noticed this as a very common mistake people make during EP and Reporting Installations. Remember that the reports need to connect to the Dynamics Ax server to run the AxQueries., which needs to pass through the .NET Business Connector. To ensure everything works fine please note the following settings: 1) Your Report Server Service Account should be same as .NET Business Connector proxy account. 2) Ensure on the server which has Reporting Services installed, the client configuration utility for Business Connector points to correct proxy account. 3) And finally, the AX instance you are connecting to has Service account specified for .NET business connector. (administration –> Service accounts –> .NET Business Connector) These simple checkpoints can help in almost most of the Business Connector related  errors, which I believe is mostly due to incorrect configuration settings. Happy DAXing!!

• Relay thru external SMTP server on Exchange 2010

  - by MadBoy

  My client has dynamic IP on which he hosts Exchange 2010 with POP3 Connector running and gathering emails from his current hosting. Until he gets static IP he wants to send emails out. This will work most of the time but some servers won't accept such email sent by Exchange (from dynamic ip due to multiple reasons) so I would like to make a relay thru external SMTP server which hosts current mailboxes. Normally SMTP server could be set up to allow relay thru it but this would require static IP to be allowed on that server so it would know which IP is allowed to relay thru it. Or is there a way to setup relay in Exchange 2010 so it can use dynamic IP and kinda authenticates with user/password itself on the hosted server?

• UTP cable for telephone line possible?

  Hi, One of my customers has build a new house with pre-installed cables for internet. The only thing he didn't think about was installing a cable for his telephone line. Behind his desk, he has a "spare" UTP cable, my question. Can this cable be used to replace a telephone line. This client has a internet and telephony contract, using a experiabox phone/internet modem. Any help would be great. I knowe I have to use a RJ11 plug.

• how do I write a functional specification quickly and efficiently

  - by giddy

  So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

• Install SSL certificate for RDP on Windows 2003?

  I need to configure SSL for RDP, and am following the instructions described here: http://thelazyadmin.com/blogs/thelazyadmin/archive/2007/01/26/Configure-RDP-over-SSL-with-SelfSSL.aspx My client's server already has a SSL certificate (.cer file), and I attempted to import it so that Terminal Services would recognize it. The importing instructions I followed are: http://support.microsoft.com/kb/816794#3. Unfortunately, when I click "Edit" from the "RDP-tcp Properties" dialog (for a Terminal Services certificate), no certificate appears. How can I get the certificate to appear here? Thanks!

• Why does QuickTime lag in Firefox if I don't put my mouse over it?

  - by Jim McKeeth

  This has happened for me as long as I can remember. Since the first version of Firefox, on multiple computers and under different versions of Windows. QuickTime plays fine in IE and Chrome (even with Firefox in the background), but in Firefox if my mouse is not over the QuickTime window then it will start to studder, then lag and eventually just stop. To be honest, I do keep quite a few tabs open, but Firefox stays at 1% CPU (even when QuickTime runs) and I have a few gigs of free RAM. It is the same for any resolution of video or audio. If the mouse is just one pixel in the client area of the QuickTime then it usually plays fine. Other video formats typically play fine. Does anyone else notice this behavior? Ultimately I would like a fix besides keeping my mouse over the QuickTime window.

• How to Fix Mail Server SSL?
