• Autohide scrollbars when not scrolling in a ListView

  - by synic

  In the new official Twitter app, the scrollbars in all the ListViews the app uses are hidden unless the user is scrolling through the list. When you start scrolling, the scrollbars appear. When you stop, they fade out with an animation until they are gone completely. I can't seem to find anything in the documentation that indicates this as being a standard feature. Is this something included in the API? If not, anyone know how this might be done?

• How to use a properties file with Hudson in compilation time?

  - by Neuquino

  Hi, I have a pom.xml that uses cxf-codegen-plugin to generate a couple of WS clients. Inside the configuration of cxf-codegen-plugin, there are the WSDL locations. I would like to externalize those strings to a env.properties file. I used org.codehaus.mojo's properties-maven-plugin to look inside src/main/resources/conf/app/env.properties. How can I make Hudson to replace those properties with the apropiate host? Thanks in advance

• Localization of attribute values in .NET

  - by Alex Angas

  How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes. Also, is there any difference to doing this with attributes declared in my own classes? Thanks!

• Apache as Reverse Proxy for CouchDB

  - by Overflown

  I'm thinking of a web app that uses CouchDB extensively, to the point where there would be great gains from serving with the native erlang HTTP API as much as possible. Can you configure Apache as a reverse proxy to allow outside GETs to be proxied directly to CouchDB, whereas PUT/POST are sent to the application internal logic (for sanitation, authentication...)? Or is this unwise -- the CouchDB built-in authentication options just seem a little weak for a Web App. Thanks

• two AES implementations generated different encryption results

  - by YCL

  I have an application that uses an opensource "libgcrypt" to encrypt/decrypt a data block (32 bytes). Now I am going to use Microsoft CryptAPI to replace it. My problem is that the libgcrypt and cryptApi approaches generate different ciphertext contents as I use the same AES-256 algoritjm in CFB mode, same key, and same IV, although the ciphertext can be decrypted by their own correspndingly. Could some tell me what is the problem? Thanks.

• virtualenvwrapper .hook problem

  - by Wraith

  I've used virtualenvwrapper, but I'm having problems running it on a new computer. My .bashrc file is updated per the instructions: export WORKON_HOME=$DEV_HOME/projects source /usr/local/bin/virtualenvwrapper.sh But when source is run, I get the following: bash: /25009.hook: Permission denied bash: /25009.hook: No such file or directory This previous post leads me to believe the filename is being recycled and locked because virtualenvwrapper.sh uses $$. Is there any way to fix this?

• Recommendations for a programmable drivers license scanner?

  - by Slapout

  Our motor pool wants to scan drivers’ licenses and have the data imported into our custom system. We're looking for something that will allow us to programmatically get the data from the scanner (including the picture) and let us insert it into our application. I was wondering if anyone has had experience with this type of system and could recommend one or tell us which ones to avoid. Our application is written in PowerBuilder and uses a DB2 database.

• PostgreSQL + Rails citext

  - by glebm

  I am trying to move to heroku which uses PostgreSQL 8.4 which has a citext column type which is nice since the app was written for MySQL. Is there any way to use :citext with rails (so that if the migrations are run on MySQL the citext would just use string/text? I found this ticket, but it seems like it isn't going to be a part of rails for a while: https://rails.lighthouseapp.com/projects/8994/tickets/3174-add-support-for-postgresql-citext-column-type
