Go to blazes. You are making me feel old. Yes, I started a computer club and I still love programming. Robotics is the next wave. Go get involved.

Comment on Obvious Idea #3: GPS Quest by David

David — Fri, 09 Mar 2012 00:35:24 +0000

The closest I’ve ever experienced to this is using Waze, the social gps app, which lets you gain points by being the first to navigate down a new street, which is accomplished by chomping pac man style dots as you go, and collecting bonus point in rare locations by seeing “themed” icons on your gps and make the detour. After wasting a few days gas on this, I gave head a shake. Tried it on my bicycle, not as much fun, as the distances to new items are too far away, at least in LA.. that was mid 2010, I’m shocked nothing has done this more justice yet, am I wrong?

Comment on Will Facebook bring back PBM games? by tnovelli

Cool. I never realized EC was so popular. Some of my friends are nuts about it. I’m starting work on a clone or take-off. It’ll be web-based of course, using HTML5 Canvas for the map.

We’re also seeking players for a bona fide game of EC starting this week… see tnovelli.net/conquest if interested.

Loved EC. I certainly wish there were a version available true to the original or at this point I would settle for a clone.

Comment on Useless magnetic sensors by Ersin

Ersin — Sat, 28 May 2011 17:43:05 +0000

Hi Joe,
I have tried to acquire data from magnetic sensors on the Sparkfun 6DOF IMU v4 for a while. And i was thinking that sensors are useless as you’re thinking. But i realize that i was using set/reset function wrong. After I apply 1-2us set/reset pulse to the magnetic sensors , the output is getting meaningful.

Comment on How to make Microsoft SQL Server cry like a baby by Joe

Well that was over three years ago, so I don’t really remember. I’m much more wise about optimizing SQL schemas these days. (And would never build things that way again in many ways.)

It sounds like you guys are randomly trouble shooting your stress test here.

First thing is find out if the problem is CPU, I/O, Network related, etc…

What are your average disk queue lengths sitting at?
high, you have a disk I/O bottle neck (controller, slow disk, bad filegroup layout, etc…)

What are your CPU averages? Over 70%
Bad index, etc…

What type of locking hints are you using in your queries? Is something blocking/dead locking you? Try sp_who2 stored procedure and look at the DBCC INPUTBUFFER({spid}) here.

You never mentioned anything about the disk setup. Usually a DB has issue with I/O before CPU depending upon the type of system it is. Now if I was talking about a web server… I would probalby be more concerned about CPU.
