Sorry if the title is a bit misleading, but this post talks about the scenario such that I have several classes, all extending the same module, and I need to avoid using shared or class variables (@@) in the module because the classes extending the module may change the shared or class variable at the same time and cause problem. So basically we have: class Test extend TestModule end class TestTwo extend TestModule end module TestModule @@val def somemethod #do something with @@val end end And the

In the afternoon I needed to replicate a database from my co-worker's CoudhDB using CouchDBX. In the replicator, I entered my co-worker's database's path like the following: http://10.0.0.3/TestDatabase And I selected to replicate to one of my existing databases. Everything seemed to be right (I could ping and telnet my co-worker's IP and CouchDB port 5984 without problem), but CouchDBX returned error 500, could not connect to remote database. After a series of diagnostics, we finally

There are a lot of resources on the Internet showing how to write and run a standalone rack application or middleware, but few showing how to write one to run in other Merb applications. This is actually very easy, so I'm going to share how I did it. Hopefully to be helpful to people in such need. The goal is to have a rack middleware in a merb application, which can be installed as gem, and then can be ued in other merb applications. First , create the merb application: $ merb-gen app application_name

By default couchdb only binds to 127.0.0.1 so it's not accepting requests from other IP addresses. The bind address setting can be modified in the configuration file. For 0.9.0, by default, the default configuration file is located at /usr/local/etc/couchdb/default.ini, and the local configuration file is located at /usr/local/etc/couchdb/local.ini. Settings in the local configuration file will override those in the default one. Bind address is in the [httpd] section [httpd] port = 5984 bind_address

I have a standalone Merb Slice which can be started by running the "slice" command in its top directory. Today I needed to make a gem file for this Slice so that people can install the gem and start it directly by running the Slice's name, for example, "foo". So I created the Rakefile, in which I specified the executable file in the following way: --- Code: Rakefile --- spec = Gem::Specification.new do |s| s.rubyforge_project = 'merb' s.name = GEM_NAME s.version =

I'm new to ruby and rspec. I wrote a ruby function and wanted to check whether it throws an exception or not in a certain situation with rspec, but I realized should_raise function no longer worked in the rspec version I was using (1.2.2). I tried to find information on the Internet and I found that I should use raise_error. However, when I wrote something like: it "description" do ObjectName.new("parameterName").should raise_error end It did not work. Finally I learned the

PROGRAMMING AND WRITING 1. Windows Mobile Starter Kits: Tic Tac Toe and Home Screen Alarm Plugin Description: These two projects were completed when I was working at Microsoft Mobile and Embedded Devices Content Publishing Team (Summer 07). Both programs were written in C++ with easy to understand documentations. I was involved in the design, development, testing and documentation processes. The Tic Tac Toe project focused on Windows Mobile Ink APIs and screen resolution awareness; the Home Screen

The command-line based CVS tool is hard to use for first time users; many GUI-based CVS tools are not really well designed to be easy to use either. I’m not against the point that developers and testers should learn how to use a technical tool in no time even though the tool is hard to use, but developers and testers have their schedules and need to be efficient. Having an efficient way to add and update files to CVS is very necessary. Eclipse is the tool I use to deal with CVS file operations

Finally Internet Explorer Mobile 6 is there and a new emulator version (Windows Mobile 6.1.4) includes IE Mobile 6 is now available to download at http://www.microsoft.com/downloads/details.aspx?FamilyId=1A7A6B52-F89E-4354-84CE-5D19C204498A&displaylang=en . Winwodws Mobile developers should certainly check this out and see how your applications can take advantage of this new IE Mobile.

I don’t see any problem doing so, but I got a question from a comment of one of my earlier post. The question states “ Hello! Could you please tell more about how to make Remote Spy++ connect to WM 5.0 emulator, which I got with MSVS2008? I've read some articles at microsoft.com, but they say you can't connect to Windows Mobile, only Windows CE... ” So I want to explain the process to connect Remote Spy to Windows Mobile emulator in Visual Studio 2008. Here are the steps
