• Ruby: How to post a file via HTTP as multipart/form-data?

  - by kch

  I want to do an HTTP POST that looks like an HMTL form posted from a browser. Specifically, post some text fields and a file field. Posting text fields is straightforward, there's an example right there in the net/http rdocs, but I can't figure out how to post a file along with it. Net::HTTP doesn't look like the best idea. curb is looking good.

• GORM "getNextException" equivalent

  - by Josh K

  GORM sits on top of [Hibernate](http://en.wikipedia.org/wiki/Hibernate_(Java). The issue is that sometimes Hibernate will throw exceptions from the JDBC driver that I can't figure out how to investigate. Specifically: Could not execute JDBC batch update; /* snip */ Caused by: java.sql.BatchUpdateException: /* snip */ [insert] was aborted. Call getNextException to see the cause. If it makes any difference I'm using PostgreSQL.

• database text field databound to a checkbox

  - by Patrick

  I'd like the field to save as a 1 or 0 instead of 'True' or 'False' in the database and i cannot figure out how to do it without manually setting every property when the record is saved. I have to use this a lot in this project and a bit field is not an option. I would like to solve this issue by extending the CheckBox control if possible but i don't know how to change the binding fields value. Any help would be greatly appreciated!

• Detect if a key does is bound to something in vim

  - by WishCow

  I'd like to know if there is a way to figure out if a key does something in vim. I know that I can use :map to see user-defined mappings, but is there something for the built-in stuff? For example, I always had CTRL-W bound to close tab, because I thought that it was unused. After half a year, I found out that there are some sequences that use it, like CTRL-W CTRL-S to split the window, and it was a nightmare to retrain myself.

• Why is this <p> expanding the whole page?

  - by George Edison

  If you visit this page and shrink your browser window, you will see my problem. [If you want to open the page in a new window, just hold down shift when you click the link.] The answers to the question extend beyond the page margin instead of wrapping. I have spent the last half hour working with Chrome's Inspector and Firefox's DOM inspector - all to no avail. I just cannot figure out why it's doing this.
