• Read Song Title/Artist from a live audio stream with Silverlight 4?

  - by Brent Pabst

  I have a SL4 project that is successfully streaming a great sounding WMA audio stream from a remote location. All of the MediaElement actions are straight forward. What I want to do is read the attributes that are passed as text along with the Audio stream. For instance the encoder of the stream embeds the title of the stream, the title of the song playing and the name of the artist for the current song. How would I pick this out using Silverlight 4 and then display it in a Label to the user? It sure would be easier than writing a bunch of web services to do the same thing. Windows Media Player and WinAmp all get the information I am just not seeing it in the MediaElement object collection.

• Cannot get NLogViewer to receive msgs from local machine

  - by slolife

  I cannot get NLogViewer to receive msgs from local machine. My machine is Windows 7. I am able to get a remote machine to send NLog messages to my local box and NLogViewer on my local box shows the message fine. But, if I run an app locally, and config NLog to spit messages to my local box, NLogViewer doesn't get the messages. Here's my config: <targets> <target name="viewer" xsi:type="NLogViewer" address="udp://localhost:4050"/> </targets> <rules> <logger name="*" minlevel="Info" writeTo="viewer" /> <rules> Is it Windows 7 security? I have config'd Windows Firewall to allow UDP port 4050 inbound and outbound. My apps are an ASP.NET site and a few windows services.

• Supplementary Developer Laptop

  - by David Silva Smith

  I'm looking to buy a laptop with the following specs for a developer. The goal will be to have a development machine supplementing the devs desktop. During work hours the dev will be on a beefy desktop. For working while on the go: trains, client sites, code camps, it would be nice to have a machine which can run Visual Studio 2008 without needing to remote desktop into their primary machine. What do you think is the lowest cost laptop meeting this need? Here are the specs I have in mind: SSD drive 64GB-doesn't need to be huge, most data is stored on servers. Will need to fit Windows 7, IIS, SQL Server, and Visual Studio 2010. RAM-3GB processor =Pentium Core 2 duo Screen size = 14 inches. OS doesn't matter. It will be paved with Windows 7 Ultimate optical drive omitted would be a plus. weight and battery life aren't so important because the machine will be plugged in almost all the time.

• DVCS and data loss?

  - by David Wolever

  After almost two years of using DVCS, it seems that one inherent "flaw" is accidental data loss: I have lost code which isn't pushed, and I know other people who have as well. I can see a few reasons for this: off-site data duplication (ie, "commits have to go to a remote host") is not built in, the repository lives in the same directory as the code and the notion of "hack 'till you've got something to release" is prevalent... But that's beside the point. I'm curious to know: have you experienced DVCS-related data loss? Or have you been using DVCS without trouble? And, related, apart from "remember to push often", is there anything which can be done to minimize the risk?

• "port forwarding": redirect calls to webservice at port 8081 to port 80

  - by niba

  Hi, a colleague of mine wrote a webservice that runs on port 8081 of our Windows 2008 Server. He uses the class ServiceHost, afaik this means its a standalone host (no IIS or ASP involvement). Note: I'm new into WCF ;) Now there are some issues with clients behind a firewall blocking the requests to remote port 8081 of our server (where the webservice runs). The easiest solution would be: run the webservice host at port 80 ... But: there is also a Apache 2.2 webserver running on the Windows Server, hosting some websites. By default it runs on port 80. My solution after some researching: use a virtual host to route requests to a virtual host (lets say http://webservice.[hostname]:80) to the webservice host (http://[hostname]:8081). Is this a good idea? Can Apache handle forwards to standalone webservice hosts? It would be nice if someone could lead me on to the right track :) Best regards, Niels

• Memcache textual protocol cheatsheet ?

  - by Maxim Veksler

  Memcached interface is implemented using a textual protocol. Sometimes it's very useful to be to fetch data stored on your remote server simply by invoking netcat with some shell kung fu, for example: To download the XML result of your nightly data crunching job you might run something like: echo "get 95ec6c7693ec53771c8a3fb1061562b8" | nc localhost 11211 > console_overview_06_04_2010.xml The interesting part here is get SOME_UNIQUE_KEY which is part of the memcached protocol. What other useful usages can you suggest in regard to the ability to interact with memcached using nothing more then command line tools? Thank you, Maxim.

• How to install Python ssl module on Windows?

  - by Jader Dias

  The Google App Engine Launcher tells me: WARNING appengine_rpc.py:399 ssl module not found. Without the ssl module, the identity of the remote host cannot be verified, and connections may NOT be secure. To fix this, please install the ssl module from http://pypi.python.org/pypi/ssl . I downloaded the package and it contained a setup.py file. I ran: python setup.py install and then: Python was built with Visual Studio 2003; blablabla use MinGW32 Then I installed MinGW32 and now the compilation doesn't work. The end of the compilation errors contains: ssl/_ssl2.c:1561: error: `CRYPTO_LOCK' undeclared (first use in this function) error: command 'gcc' failed with exit status 1 What should I do?

• MapView Annotation Callout action when opened

  - by Paul Peelen

  Hi, I have a mapview with serveral annotations. Every annotation has a leftCalloutAccessoryView which is a UIViewController class. The reason for this is that I want every annotation to load some data from the server, and add the result of that data to the annotation subTitle. This all works perfectly, except that I dont want to load all that data when my app is started, but I want to the remote call to be done only when the callout bubble is opened. Does anybody know how I can do this? The viewWillload, viewDidLoad ect. don't work in this case. Any examples as well? Best regards, Paul Peelen

• Synchronize model in MySQL Workbench

  - by Álvaro G. Vicario

  After reading the documentation for MySQL Workbench I got the impression that it's possible to alter a database in the server (e.g. add a new column) and later incorporate the DDL changes into your EER diagram. At least, it has a Synchronize Model option in the Database menu. I found it a nice feature because I could use a graphic modelling tool without becoming its prisoner. In practice, when I run such tool I'm offered these options: Model Update Source ================ ====== ====== my_database_name --> ! N/A my_table_name --> ! N/A N/A --> ! my_database_name N/A --> ! my_table_name I can't really understand it, but leaving it as is I basically get: DROP SCHEMA my_database_name CREATE SCHEMA my_database_name CREATE TABLE my_table_name This is dump of the model that overwrites all remote changes in my_table_name. Am I misunderstanding the feature?

• Maintain set of local commits working with git-svn

  - by benizi

  I am using git to develop against a project hosted in subversion, using git-svn: git svn clone svn://project/ My general workflow has been to repeatedly edit-and-commit on the master branch, then commit to the svn repository via: git stash git svn dcommit git stash apply One of the local modifications that 'stash' command is preserving, that I don't want to commit to the svn repository, is a changed database connection string. What's the most convenient way to keep this local change without the extra 'stash' steps? I suspect that something like 'stash' or 'quilt' is what I'm looking for, but I'm still new enough to git that I think I'm missing some terminology that would lead to the exact incantation. Update: The only solution I found that seems to avoid the git stash + git-svn action + git stash apply series was to update the git-svn ref manually: (check in local-only change to 'master', then...) $ cat .git/refs/master > .git/refs/remote/git-svn $ git svn fetch (with at least one new SVN revision) And that leaves the local-only commit as a weird (probably unsafe) commit between two svn revisions.

• java.security.AccessControlException: access denied using Java Web Start

  - by killiancomputers

  I am having some issues with accessing files using JWS (Java Web Start). The program adds a new label and image. The program runs fine on my local computer but gives me pages of errors when I run the program on my remote server using JWS. Here's a sample of the error: Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission add2.png read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) This occurs even after making sure the images have read access. Ideas?

• WCF Service worker thread communicate with ServiceHost thread

  - by Brent

  I have a windows NT Service that opens a ServiceHost object. The service host context is per-session so for each client a new worker thread is created. What I am trying to do is have each worker thread make calls to the thread that started the service host. The NT Service needs to open a VPN connection and poll information from a device on the remote network. The information is stored in a SQL database for the worker threads to read. I only want to poll the device if there is a client connected, which will reduce network trafic. I would like the worker threads to tell the service host thread that they are requesting information and start the polling and updating the database. Everything is working if the device is alway being polled and the database being updated.

• Max TCP Connections to a machine

  - by A9S6

  I am creating a Windows Service in .NET to which N number of client can connect. The service starts a TCP listener and accepts the client connections. The problem I am facing is that I can only open 10 connections to this service. The listener::AcceptTcpClient() method accepts only 10 connection and throws an exception for 11th one. The client application uses the System.Net.Sockets.TcpClient class and the service is using System.Net.Sockets.TcpListener class. This is the exception that I am getting when I try to make a number of connections in a for loop to this service (after the 10th connection is made): "Unable to read data from Transport connection: An exsting connection was forcibly closed by remote host"

• Update to php5.3 breaks connecting to mysql db

  - by bobbyb

  I just updated php to 5.3 and can no longer connect to my remote mysql server. I get the following errors: mysqli_connect(): OK packet 6 bytes shorter than expected mysqli_connect(): (HY000/2000): mysqlnd cannot connect to MySQL 4.1+ using old authentication It seems this has to do with the new mysqlnd driver. Is there a way to force it to use the old libmysql driver. Also, reverting to php5.2.11 doesn't seem to fix the issue which seems to work for most people. Anyone have any suggestions? thanks!

• Are the svn ruby bindings provided as a gem?

  - by user30997

  I see a couple dozen gems that relate to svn, but what little documentation I can find on any of them shows that they are command-line wrappers and misc helpers. (svn-command, svn-hooks, etc.) I've seen code in the wild that does things like: require 'svn/core' and SVN.Repos.add(...), but the author of that module pulled his svn ruby tools via apt-get. This would not be an option for me, as I'm developing a windows/osx tool. Which gem am I after? From there, I'm happy to dig through code in lieu of documents, but with a call to gem query --name-matches svn --remote returning about 30 hits, I need to narrow it down a bit first.

• How to access the Principal from a Java service object without using FlexContext?

  - by Marplesoft

  We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

• Change present working directory of a calling shell from a ruby script

  - by Erik Kastman

  I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

• Enterprise distribution Program for iPhone

  - by Mohammed Sadiq

  Hi all, I would like to implement a application which backs up all the internal datas like sms, mms, videos, audios, documents, call history stored in iPhone. But this seems to be not possible with api docs that the apple has released so far ... I have gone through the pdf of ENterprise distribution program and some of the links related to Enterprise Distribution Program, specifies about the Remote wipe and accessing of internal datas like Calendar, sms, mms ect .... But they didnt mention how to do it programmatically. Does Apple provide any special priviledges like extra api support to access the internal data in their Enterprise Distribution Program?. Is there any difference between Enterprise Distribution Program and Standard Distribution Program in the development point of view? And since in-house distribution does not require Apple approval, shall we use some other method which are not officially mentioned in apple docs, to access the internal stored data .. If so can anyone point out the way to do it? Any help would be greatly appreciated awaiting for your response Best regards, Mohammed Sadiq ....

• HTTP 404 Error manifests itself as EndPointNotFoundException on a WCF client

  How can I make my client treat 404 Error correctly? Right now it catches a general exception... My WCF Server uses WebOperationContext.Current.OutgoingResponse.SetStatusAsNotFound(); To return a 404 Error code however my WCF client interperts it as an EndPointNotFoundException There was no endpoint listening at http://myUrl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception is WebException "The remote server returned an error: (404) Not Found.
