• Proper way to bind WCF webservice to both HTTP (for dev) and HTTPS (for production)

  - by Nicholas H

  Seems like this would be fairly straightfoward but I can't figure it out. In lieu of using an ASMX web service, I'm trying to go with WCF.. and finding it hard to figure out bindings. I would like to be able to use HTTP to connect to the WCF service for local development (and on our "staging" server), but require HTTPS on our production server. Should this be possible with two bindings? I cannot get it to work. If someone could provide an example of just a very basic HTTP and HTTPS WCF setup, I'd be eternally grateful. Or point me to a book/website/etc. which solves all the mysteries of WCF.. that'd be great. Because right now it's looking easier to just go back to ASMX.

• Modal View Controller Undesirably Hides Tab Bar

  - by Kevin Sylvestre

  I am working on an application that requires user authentication to access a profile. The profile section is located solely under one tab (and all others tabs do not require authentication). I currently present a authentication view controller modally (and then dismiss on success) when the user selects the profile tab. However, this approach prevents the user from deciding not to register / login (that is, all tabs are hidden once the authentication screen is presented modally). I don't want the user to be able to dismiss the modal view controller, but rather have it modal only for the profile tab. Is this possible? Can I have tabs visible while having a modal view controller? What is the best approach here. Thanks.

• piping findstr's output

  - by Gauthier

  Windows command line, I want to search a file for all rows starting with: # NNN "<file>.inc" where NNN is a number and <file> any string. I want to use findstr, because I cannot require that the users of the script install ack. Here is the expression I came up with: >findstr /r /c:"^# [0-9][0-9]* \"[a-zA-Z0-9_]*.inc" all_pre.txt The file to search is all_pre.txt. So far so good. Now I want to pipe that to another command, say for example more. >findstr /r /c:"^# [0-9][0-9]* \"[a-zA-Z0-9]*.inc" all_pre.txt | more The result of this is the same output as the previous command, but with the file name as prefix for every row (all_pre.txt). Then comes: FINDSTR: cannot open | FINDSTR: cannot open more Why doesn't the pipe work? snip of the content of all_pre.txt # 1 "main.ss" # 7 "main.ss" # 11 "main.ss" # 52 "main.ss" # 1 "Build_flags.inc" # 7 "Build_flags.inc" # 11 "Build_flags.inc" # 20 "Build_flags.inc"

• Java obfuscators

  - by jbu

  I'm looking for a good Java obfuscator. I've done initial research into the following Java obfuscators: proguard, yguard, retroguard, dasho, allatori, jshrink, smokescreen, jobfuscate, marvin, jbco, jode, javaguard, jarg, joga, cafebabe, donquixote, mwobfu, bbmug, zelix klassmaster, sandmark, jcloak, thicket, blufuscator, and java code protector. I tried proguard and it has a really nice GUI, seems really stable, and seems to be the most popular, but it seemed to not like some enumeration on a referenced jar file (not within the code I was trying to obfuscate) which was weird. Yguard seems to require some interaction with ant, which I didn't know too much about. What is a good java obfuscator? It doesn't need to be free, it just needs to work well and be easy to use.

• Template engine recommendations

  - by alex

  I'm looking for a template engine. Requirements: Runs on a JVM. Java is good; Jython, JRuby and the like, too... Can be used outside of servlets (unlike JSP) Is flexible wrt. to where the templates are stored (JSP and a lot of people require the templates to be stored in the FS). It should provide a template loading interface which one can implement or something like that Easy inclusion of parameterized templates- I really like JSP's tag fragments Good docs, nice code, etc., the usual suspects I've looked at JSP- it's nearly perfect except for the servlet and filesystem coupling, Stringtemplate- I love the template syntax, but it fails on the filesystem coupling, the documentation is lacking and template groups and stuff are confusing, GXP, TAL, etc. Ideas, thoughts?

• Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

  - by user3611500

  I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.

• Transfer file using BITS without using IIS on one end?

  - by rwmnau

  I know that I can transfer files using BITS and a wrapper like SharpBITS, but it seems that I need an IIS server on one end - either to upload to or download from. Is there a way to use the BITS protocol to transfer a file without requiring IIS? Some kind of a "BITS Server" or "Listener" project that my client's BITS service can connect to. I'm looking for functionality that's exactly what BITS provides, but I'd prefer not to require that IIS be installed (though if I have to, I can). Thanks!

• Speed Difference between native OLE DB and ADO.NET

  - by weijiajun

  I'm looking for suggestions as well as any benchmarks or observations people have. We are looking to rewrite our data access layer and are trying to decide between native C++ OLEDB or ADO.NET for connecting with databases. Currently we are specifically targeting Oracle which would mean we would use the Oracle OLE DB provider and the ODP.NET. Requirements: 1. All applications will be in managed code so using native C++ OLEDB would require C++/CLI to work (no PInvoke way to slow). 2. Application must work with multiple databases in the future, currently just targeting Oracle specifically. Question: 1. Would it be more performant to use ADO.NET to accomplish this or use native C++ OLE DB wrapped in a Managed C++ interface for managed code to access? Any ideas, or help or places to look on the web would be greatly appreciated.

• Test (with RSpec) a controller outside of a Rails environment

  - by ramon.tayag

  I'm creating a gem that will generate a controller for the Rails app that will use it. It's been a trial and error process for me when trying to test a controller. When testing models, it's been pretty easy, but when testing controllers, ActionController::TestUnit is not included (as described here). I've tried requiring it, and all similar sounding stuff in Rails but it hasn't worked. What would I need to require in the spec_helper to get the test to work? Thanks!

• Where do I find a good explanation of Javascript-ese

  - by tzenes

  I realize that title may require explanation. The language I first learned was C, and it shows in all my programs... even those not written in C. For example, when I first learned F# I wrote my F# programs like C programs. It wasn't until someone explained the pipe operator and mapping with anonymous functions that I started to understand the F#-ese, how to write F# like a F# programmer and not a C programmer. Now I've written a little javascript, mostly basic stuff using jquery, but I was hoping there was a good resource where I could learn to write javascript programs like a javascript programmer.

• Timezones and the DateTimeField - Django

  - by RadiantHex

  Hi folks, I'm trying to implement a "time ago" feature, for the displaying of items on a site. As I'm caching the pages I wish to use javascript in order to render the "time ago". Javascript knows local time and problably the Timezone of the local machine so I could play with that, but that would require to hard code the server's timezone. Therefore I'm trying to figure out a simple way to pass a ISO 8601 timestamp, in GMT time. Is there any simple and straight forward way for doing this? Help would be much appreciated! =)

• xapian-full installed on mac os x snow leopard but failed with dlopen LoadError

  Since I have tried to install xapian but failed, I try another alternative with xapian-full.

• Selectively configuring Apache 2 mod_headers for Google Chrome Frame

  - by Adam Cobb

  I am currently evaluating Google Chrome Frame and so far i'm happy with it, but what i'd like to do is selectively use it for certain sections of my website. Some sections require ActiveX so need to be viewed in native IE, whereas others benefit greatly, and may end up requiring, Chrome Frame. I've currently got the following configured in my apache httpd.conf file - <IfModule mod_setenvif.c> <IfModule mod_headers.c> BrowserMatch chromeframe gcf Header append X-UA-Compatible "chrome=1" env=gcf </IfModule> </IfModule> This causes anything coming in via Apache to get the chrome frame stuff added to the headers. What I need is to make this only happen when a user visits particular URL's / particular pages, which i'm currently controlling via RewriteRules. Could anybody explain how I would go about this, as my understanding of the Apache config files isn't brilliant. Thanks.

• OS X firewall popup about growlnotify keeps popping up

  - by Vitaly Kushner

  I have autotest setup with growlnotify using growl_glue (version 1.0.7): require 'growl_glue' GrowlGlue::Autotest.initialize do |config| config.notification :use_network_notifications => true end growl version is 1.2 each time autotest runs and displays the notification growl popup I also get an OS X firewall popup asking Do you want the application "growlnotify" to accept incoming network connections? I tried answering deny and allow but it still keeps popping up. the deny/allow choice is properly reflected in System Preferences - Security - Firewall - 'application access list', but it still asks every time. update I ended up using autotest-growl gem instead of the growl_glue. it fixed the problem, it was probably related to how growl_glue was calling growlnotify.

• Create Class functions on the fly?

  - by JasonS

  Hi, i have a validation class which needs improving. If I require some custom validation I need to specify a custom function. It works a bit like this: The controller tells the validation that a custom validation function is required. The controller runs the validation. --- Gets iffy here --- Validation class creates a new instance of the controller class.... Validation class runs controller-custom_validation_function() Validation class returns true / false Is there someway that I can alter this to do something like this? $validation = new validation; // Insert rules here. $validation-function() = $this-function(); By doing this I could get rid of the step of creating an unneeded class instance.

• WCF VS. Sockets

  - by kite

  Hello, I would like to know which of WCF or .NET Sockets is the more efficient and the more recommended in a game developpment scenario. Here are the different parts of the game : -a client/server communication to play on the internet -peer to peer on local network. I would like to know which technology you would use on these parts (wcf on both, socket on both, wcf on one and socket on the other...) and why, if possible. The game involved doesn't require a high communication frequency (3-4 per second is enough). Thanks, KiTe

• How to generate a client certificate using a third party CA-NOT Self Signed CA

  - by Bryan

  I am trying to trying to export a client certificate for use with a web browser. The goal is to restrict access using the <Location directive to the admin area. I have seen numerous tutorials on using self signed CAs. How would you do this using a third party? 1) Do I need to include the CA in the client pfx if it is a trusted root CA? I have seen both examples. Without CA: openssl pkcs12 -export -inkey KEYFILENAME -in CERTFILEFILENAME -out XXX.pfx With CA: openssl pkcs12 -export -in my.crt- inkey my.key -certfile my.bundle -out my.pfx 2) Do I need to still include SSLCACertificateFile for trusted CA in the httpd.conf setup? SSLVerifyClient none SSLCACertificateFile conf/ssl.crt/ca.crt <Location /secure/area> SSLVerifyClient require SSLVerifyDepth 1 </Location> http://www.modssl.org/docs/2.8/ssl_howto.html#ToC8

• Difficulties signing in to Twitter from iPhone

  - by Tristan

  Hi there, I'm using MGTwitterEngine to add Twitter functionality to my app. It's very easy to simply prompt the user for a username and password and then start posting. Strangely, however, I've noticed other apps (eg Foursquare and Brightkite) require you to visit their website to associate your Twitter account with your foursquare/brightkite/whatever account. Why do they do it this way? Is there a reason why my app shouldn't prompt the user for a Twitter username and password, even though it would be so easy? Thanks a bunch! Tristan

• What language has the longest "Hello world" program?

  - by Kip

  In most scripting languages, a "Hello world!" application is very short: print "Hello world" In C++, it is a little more complicated, requiring at least 46 non-whitespace characters: #include <cstdio> int main() { puts("Hello world"); } Java, at 75 non-whitespace characters, is even more verbose: class A { public static void main(String[] args) { System.out.print("Hello world"); } } Are there any languages that require even more non-whitespace characters than Java? Which language requires the most? Notes: I'm asking about the length of the shortest possible "hello world" application in a given language. A newline after "Hello world" is not required. I'm not counting whitespace, but I know there is some language that uses only whitespace characters. If you use that one you can count the whitespace characters.

• Java getMethod with superclass parameters in method

  - by Jonathon

  Given: class A { public void m(List l) { ... } } Let's say I want to invoke method m with reflection, passing an ArrayList as the parameter to m: List myList = new ArrayList(); A a = new A(); Method method = A.class.getMethod("m", new Class[] { myList.getClass() }); method.invoke(a, Object[] { myList }); The getMethod on line 3 will throw NoSuchMethodException because the runtime type of myList is ArrayList, not List. Is there a good generic way around this that doesn't require knowledge of class A's parameter types?

• COMET with [Session ] TimeOut

  - by Amitd

  hi guys, Just Wondering how [Session] timeouts are(or can be) implemented when using Comet? I'm using Long polling Comet solution and want to implement a kind of Timeout feature. Example : If the user is on a Comet enabled page and doesn't respond to server events/notification for a period of time say 10 mins then invalidate his session and remove his request from server and redirect the user to a timeout page? Will this require Javascript XHR requests to check for a timeout explictly? Using ASP.NET 3.5 / C# (Doesn't need to be language specific) Thanks

• How to test COM object integrity automatically?

  - by sharptooth

  Every COM object must have integrity. In simplified terms this means that if an object implements 3 interfaces - A, B and C and I have A* pointer to the object I must be able to successfully QueryInterface() both B and C and having B I must be able to retrieve A and C and having C I must be able to retrieve A and B. Now my object implements 5 interfaces and I want to test its integrity. Writing checks for all of the above myself will require a substantial effort. Is there a tool or some easily tweakable code or a code pattern that would do it?

• JSP load external php not using iFrames

  - by Rudiger

  I have a bit of an issue with a site I maintain. I have been asked to add a report to a page that sits in a jsp page. The reporting information comes from a MySQL database. The problem is to connect the jsp to the database would require added functions to code that I do not have the original source of. I thought about redoing all the db connection again but thats a lot of time for something that will probably be rewritten in 3 weeks. Then I thought of just using PHP to display the report in the jsp as I have other pages connecting to the database using php (long story as to why were are using 2 languages). But the only way I know of is by using iFrames which is a bit of a no no. Using the object tag I've seen also has errors in IE. What would be the best way to do this?
