== MIA ==
== About Strife ==


I may be MIA for the next month. I. My current computer is inadequeate for SL as this is my backup, my main computer died in August. Here's a glimpse of my ToDo list: Get a job, find a new place to live, get a new computer.
=== Synopses ===
It may seem that Strife is MIA, well Strife's computer died several months ago... then the LCD on the backup failed... then the CRT on the backup decided the only resolution it wants to run at is 800x600 at 60hz. So Strife really can't do much until the computer gets rebuilt. To add to that, Strife will soon be moving to a yet unknown location. While a new computer would be nice, it's not a wise investment at the moment. Did I forget to mention the need for a job? -- So things are pretty stressed.


It's moving day, and this may be the last you hear from me for a while. Going to dismantle the computer last. -- '''[[User:Strife_Onizuka|Strife]]''' <sup><small>([[User talk:Strife_Onizuka|talk]]|[[Special:Contributions/Strife_Onizuka|contribs]])</small></sup> 01:06, 21 December 2008 (UTC)

About Strife

Synopses

Strife is an avid scripter, wiki author and SL forum denizen. Not content in selfish information gathering he shares what he knows through various mediums, so that others may benefit and learn. He volunteers his time to work on many public projects which include: giving scripting advice, writing LSL documentation, providing and improving LSL scripts and libraries.

SL Status

Strife currently has a part time job, soon to be more fully employed and back in SL. After a catastrophic computer failure in the summer of 2008 and subsequent upsetting of housing situation found it ever more difficult to get online.

Honors

Through his public works Strife became a pillar of the SL community.

Strife is a Hippo award winner, awarded "Best Community Organizer" in the 2007 Linden Lab Innovation Awards, and here is his mention as a runner-up in the 2008 "Best Documentation" category: "Last year's winner, Strife Onizuka, continued to be insanely prolific, with thousands of edits over the past year.... Anyone learning LSL is almost certainly indebted to Strife's work in some way."

Own Words

I'm an immigrant from URU. Was in all 3 of it's beta's.

Wiki Gnome (causing drama isn't why I'm here).

I have a webpage but haven't updated it in a few months...

Wiki's are the way of the future when it comes to making documentation Ad-hoc but eventually become static as graffiti grows with popularity as a way of controlling it.

also contribute to some other wiki's

When it comes to writing I tend to go towards concise. A short accurate description is better then a long equally accurate description; less to get confused with, easier to find the important information (because it is all important).
