External files CMD/ST3... sadness.

If you created your app with Sencha Command then you should not edit index.html. Instead you should add JS files to the js property of app.json.

This is like, annoying at best.

Sencha Touch is different from ExtJS

I've done Extjs4 for awhile and thought ST2 would be the same way. In fact, I've even built an app with ST2. Turns out I didn't know a few basic things.

One of them is that classes take a config object. This is important! My form just kept on never displaying because I was used to putting fields on the class itself not in the form object.

Also, scaffolds are very very useful. Use them!

Accessing Postgres UUID with JPA

http://stackoverflow.com/questions/11284359/persisting-uuid-in-postgresql-using-jpa

JPA 2.1 provides a very easy way to use the PostgreSQL uuid column type and java.util.UUID as the type of the corresponding entity field:

@javax.persistence.Converter(autoApply = true)
public class PostgresUuidConverter implements AttributeConverter<UUID, UUID> {

    @Override
    public UUID convertToDatabaseColumn(UUID attribute) {
        return attribute;
    }

    @Override
    public UUID convertToEntityAttribute(UUID dbData) {
        return dbData;
    }

}

Just add this class to your persistence configuration and annotate UUID fields with@Column(columnDefinition="uuid").

Requests.py

I needed to do some RESTful calls via command line.

Naturally, I could have used curl, but I wanted to save my commands.

I remember I used Python a long time ago, so I was investigating curling via Python. There is a pycurl library, but this one seemed simple and fun.

To set up,

Get the Code

Requests is actively developed on GitHub, where the code is always available.

You can either clone the public repository:

git clone git://github.com/kennethreitz/requests.git

Download the tarball:

$ curl -OL https://github.com/kennethreitz/requests/tarball/master

Or, download the zipball:

$ curl -OL https://github.com/kennethreitz/requests/zipball/master

Once you have a copy of the source, you can embed it in your Python package, or install it into your site-packages easily:

$ python setup.py install

Super simple, very fun!
It just works!
