• crash_counter And here is where we keep track of all the things we broke while flying.
• space_related_documents A page with a list of resources, documents, templates that are space-related.
• open_source_brewing_resources A page with lists of resources for (home)brewers using open source/standards
• led-n-sound-toy An idea i've been working on
• JustaDome Standardized miniature-sized 'festival-dome' from trashed bed-slats
• Cornelius-Kegs_Howto Explanation on what they are and how to use them; as broad as possible.
• Justa_Beer_Brewing_Howto An attempt at giving a bird-flight overview into what goes into brewing beer, written down from my totally biased, unscientific, vantage-point.

Personal interests

Just a postit-note for myself with info on mediawikidb select user.user_id,user.user_name,user_email,user.user_email_authenticated from user where user_id not in (select distinct ipb_user from ipblocks); or select user.user_id,user.user_name,user_email,user.user_email_authenticated from user left join ipblocks on user.user_id = ipblocks.ipb_user where ipblocks.ipb_user IS NULL;

Personal short-term goals

Get Interspatial Pale ale working Get ACTA-doorbell project installed with help of Brainsmoke (aka: aid him in all i can) Get INFO-board (screenly) working for ACTA/UR in the hallway to get rid of ridiculous HP issues membership_process_wip
