• VirtualHost problem with passenger (mod_rails)

  - by Jake

  Hi all, I'm at my wit's end here with virtual hosting. I'm trying to install redmine and it works with the webrick test server, but when I tried to use passenger (mod_rails) to host and go to the address I specified when in the virtualhost part of my apache config file nothing happens. Here is the relavent section of /etc/httpd/conf/httpd.conf where I try to set up the virtual host: <VirtualHost *:80> SetEnv RAILS_ENV production ServerName redmine.MYSITE.com:80 DocumentRoot /opt/redmine-1.0.5/public/ <Directory /opt/redmine-1.0.5/public/> Options -MultiViews Allow from all AllowOverride none </Directory> However, when I got to redmine.MYSITE.com:80 nothing happens, I just get our normal home page. I have no idea what the problem is, any help our guidance would be greatly appreciated. If you need any other information, please tell me and I'll provide it.

• problem in multiple asynchronous calls on webservice method in wpf application

  - by black sensei

  Hello Experts! i'm trying to create an application which connects to internet and consume web services for every of it's operation.As far as i'm concerned i'll like to useasync method which i'm using already to get a collection of Contacts.I've realized that when i'm doing the same for groups (meaning getting groups async) i'm having errors in the calls , but when using normal call there ins't.So i did some research online and find that a lot of people has the same problem. Some of them are asked to use WCF (for which i don't know jack).I'll like to know if there is another way to overcome this. if not can somebody point me to reliable resource online and help me get through it? thanks for reading and helping

• C++'s char * by swig got problem in Python 3.0

  - by gpliu3

  Our C++ lib works fine with Python2.4 using Swig, returning a C++ char* back to a python str. But this solution hit problem in Python3.0, error is: Exception=(, UnicodeDecodeError('utf8', b"\xb6\x9d\xa.....",0, 1, 'unexpected code byte') Our definition is like(working fine in Python 2.4): void cGetPubModulus( void* pSslRsa, char* cMod, int* nLen ); %include "cstring.i" %cstring_output_withsize( char* cMod, int* nLen ); Suspect swig is doing a Bytes-Str conversion automatically. In python2.4 it can be implicit but in Python3.0 it's no long allowed.. Anyone got a good idea? thanks

• Problem with Clojure function

  - by Bozhidar Batsov

  Hi, everyone, I've started working yesterday on the Euler Project in Clojure and I have a problem with one of my solutions I cannot figure out. I have this function: (defn find-max-palindrom-in-range [beg end] (reduce max (loop [n beg result []] (if (>= n end) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range beg end))))))))) I try to run it like this: (find-max-palindrom-in-range 100 1000) and I get this exception: java.lang.Integer cannot be cast to clojure.lang.IFn [Thrown class java.lang.ClassCastException] which I presume means that at some place I'm trying to evaluate an Integer as a function. I however cannot find this place and what puzzles me more is that everything works if I simply evaluate it like this: (reduce max (loop [n 100 result []] (if (>= n 1000) result (recur (inc n) (concat result (filter #(is-palindrom? %) (map #(* n %) (range 100 1000)))))))) (I've just stripped down the function definition and replaced the parameters with constants) Thanks in advance for your help and sorry that I probably bother you with idiotic mistake on my part. Btw I'm using Clojure 1.1 and the newest SLIME from ELPA.

• capistrano deployment with use_sudo=true - permissions problem

  - by Pavel K.

  i am trying to do a deployment with capistrano to newly installed Ubuntu server i am deploying to directory /var/www, owned by root, so i need to set use_sudo to true while i execute commands with run "#{try_sudo} command" without problem, svn checkout doesn't work with sudo prefix i try set :deploy_via, :export and it throws Can't make directory '/var/www/pr_name/releases/20091217171253': Permission denied during checkout i imagine adding "try_sudo" prefix to "svn export" would help, but where can i edit the one it uses in deploy_via? -- if on other hand i don't use use_sudo, and set /var/www/ directory ownership to myuser, i still cannot deploy - some of my deployment commands set folders ownership to apache user www-data and then i get something like: changing ownership of `/var/www/pr_name/current/specificdirectory': Operation not permitted which, if i understand correctly, has to be done with sudo

• Problem with updating multiple rows which are in conflict with unique index

  - by GUZ

  I am using Microsoft SQL Server and I have a master-detail scenario where I need to store the order of details. So in the Detail table I have ID, MasterID, Position and some other columns. There is also a unique index on MasterID and Position. It works OK except one case: when I have some existing details and I change their order. For example when I change a detail on position 3 with a detail on position 2. When I save the detail on position 2 (which in the database has Position equal to 3) SQL Server protests, because the index uniqueness constraint. How to solve this problem in a reasonable way? Thank you in advance Lukasz Glaz

• Problem when reading backslash in Prolog

  - by Jerry

  I'm writing a lexer in Prolog which will be used as a part of functional language interpreter. Language spec allows expressions like for example let \x = x + 2; to occur. What I want lexer to do for such input is to "return": [tokLet, tokLambda, tokVar(x), tokEq, tokVar(x), tokPlus, tokNumber(2), tokSColon] and the problem is, that Prolog seems to ignore the \ character and "returns" the line written above except for tokLambda. One approach to solve this would be to somehow add second backslash before/after every occurrence of one in the program code (because everything works fine if I change the original input to let \\x = x + 2;) but I don't really like it. Any ideas?

• Kohana v2 - problem with routes

  - by yoda

  Hi, I'm attempting to set some custom routes in Kohana v2. What I'm looking for is some method that allow the system to : follow a pre-defined name to it's related root; redirect the non-matched url's into another controller; To give you a more clear view over the problem, I want the first url parameter to be associated to certain pages (contacts, home, services, about us, etc), and those urls who doesn't match the previous pages would be routed into a controller called products, in order to determine if the first url parameter regards a product name. Here's a sample of what I have : $config['_default'] = 'home'; $config['([a-zA-Z]+)'] = 'products/showcat/$1'; What am I missing here? Thanks in advance!

• Problem with assembly loading in .NET

  - by Jamie

  Hi guys, I have got two projects in my solution: Silverlight and standard one. The standard one references System.Xml assembly (version 4.0.0.0), however the Silverlight one references System.Xml assembly (v. 2.0.5.0). I want to make an instance of XmlWriter in my Silverlight project. Here comes the problem - the exception is thrown (file not found for System.Xml assembly). I believe it is a matter of different assembly versions. Do you have any idea how to resolve this issue? Ive read something about the binding redirection - is it the key to the solution? If so, how to do this? Thank you in advance for the reply! Cheers.
