  - by Juha Syrjälä

  Do you know any open source software that uses Orient DB? Or have you used that product yourself? Any experiences to share? I have recently looked into Orient DB, and it has nice and feature interesting feature set (fast, embeddable in Java, simple API) but it seems that it is not widely used. Is it just because the Orient DB is a new player on the field?

• Is it possible to determine if two git branches will merge cleanly without affecting the working dir

  - by Andrew Cantino

  You can determine with git merge-base if a fast forward is possible, but is there some git trick to determine if two branches will merge cleanly with some strategy without actually doing the merge? I know about "git merge --no-commit --no-ff $BRANCH" but that affects the working directory, which I'd like to avoid since this is part of a webservice.

• Something like PPerl for Ruby?

  - by sal

  I've used PPerl for deamon like processes. This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once. Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.

• Is there any way to run "dir" directly?

  - by Mason Wheeler

  In my answer to this question, where the asker needed a fast way to get a directory listing of a folder on a network drive, I suggested using the DOS "dir" command. Unfortunately, it's a command, not a program, so you can't execute it with CreateProcess and so I had to put it in a batch file. I don't really like that solution. It feels like a hack to me. Does anyone know a way to run dir from Delphi instead of from an external batch file?

• Do non-clustered indexes slow down inserts?

  - by mikeinmadison

  I'm working in Sql Server 2005. I have an event log table that tracks user actions, and I want to make sure that inserts into the table are as fast as possible. Currently the table doesn't have any indexes. Does adding a single non-clustered index slow down inserts at all? Or is it only clustered indexes that slow down inserts? Or should I just add a clustered index and not worry about it?

I looked at other CMSs' like Drupal and Joomla but it looks like its difficult to make them use custom tables.
