Hive13 exists!

Wednesday, July 1st, 2009

On June 30 2009, members of Hive13 met for the first time in their newly acquired building. With 3500 sq ft of space, 15ft celings, and its central proximity, 2929 Spring Grove Ave.  is looking to be one hell of a workshop. (With a kitchen and huge bar, nice lounge, machinery, tools, games, memes, etc).

So put on your happy pants and/or shoes and head on over to www.Hive13.org

More fun with Excel, vim saves the day

Monday, June 1st, 2009

My fun with Excel continues.  I exported a sheet to a CSV and it had lovely Microsoft formatted characters such as ” and ” that needed replacing.  When you look at these in vim or less, you will see items like <92> and <93>.  To replace these, just do:

:%s/Ctrl+V x 92//g

That’s hold Ctrl and hit v, then release Ctrl, hit x, and type 92.  You will see vim respond accordingly.  MS DIAF IMO.

Replacing wildcards in Excel

Tuesday, May 26th, 2009

I have the joy of working on an Excel spreadsheet right now.  To replace an asterisk or wildcard, you must escape the character with a tilde.  For example, changing all * to .+ would be Ctrl+H to bring up the Replace window, then use ~* for your search character and .+ for your replacement.
