• When is shared code ownership useful?

  - by alchemical

  I've worked on several projects lately that have promoted the idea of shared code ownership. At times, this seemed to speed up code-improvement and enhancement. Other times, it seemed to become a ground of ego-jousting with changes being made to support individuals coding styles, favored technologies, or simply a demonstration of power/intellect. How can shared code ownership be implemented to avoid the pitfalls and still reap the benefits? Can too many cooks spoil the broth?

• Is there an analog for the VI '.' command to repeat-last-typed-text

  - by Don

  I've used emacs for decades and always wondered, but kept on coding, if there was a way to type in something, them move the cursor and insert the same text, like the VI . command. Instead what I do is to type the text, set the mark, backup, copy the region, go to the next spot (often just C-n, down one line) and then pre-arg yank, C-u C-y. It's the overhead of set mark, backup and copy region that makes me just go ahead and retype the thing.

• database splitting; multiple tables

  - by Ben

  I am coding a classifieds ad web app. What is the optimal way to structure the database for this? Because of the high repeatability, would it be faster (in terms of searching/indexing) to have a separate table in the database for each city? Or would it be okay to just have one table for every city (it would have a lot of rows..). The classifieds table has id, user_id, city_name, category,[description and detail fields].

• Partials vs for loop — best practices

  - by Mike

  In coding up your view templates you can render a partial and pass an array of objects to be rendered once per object. OR you can use a For blank in @blank loop. How do you decide when to do which? It seems that if you use a partial for every iterable object you will end up having to modify tons of separate files to make changes to potentially one view. With the loops you can see everything right there in one file.

  - by Toran Billups

  I'm trying to add a range of - 365 days and + 365 days but it appears that using this attribute in EL 4.1 only accepts a special ISO formatted string ... thus I can't simply add a normal string to this validation routine. <DateTimeRangeValidator(DateTime.Now.AddDays(2), DateTime.Now.AddDays(4))> _ I wanted to do something similar to the above - fyi Does anyone know how you can force this attribute to accept this ISO formatted string w/out hand coding this value?

  My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out.
