It took the AT&T U-Verse tech over five hours to work through all the installation issues but we finally completed the upgrade to the 45 Mbps service (tested a bit over 50 Mbps, don't know how that's possible…).

Next stop, gigabit fiber!

Barbie, Remixed: I (really!) can be a computer engineer.
I am a PhD student in a computing department, so I guess it’s not surprising that my social media feeds have been full of outrage over Barbie’s “computer engineering” skills. The blog post that ori…

And we wonder why girls don't grow up to be young women who pursue STEM studies and careers?

Pamie » Barbie Fucks It Up Again
I recently paid a visit to my sweet friend Helen Jane and was excited to find this book at her house. barbie1. (The second book of the “2 Books in 1!” is “Barbie [i can be…] an Actress.” We’ll get to that later.) Helen Jane has two little girls under the age of six.

 

More photos of the rod and bearing damage from the Miata engine

Written by vtluu on November 17th, 2014
The #1 rod end has a dark spot and the corresponding rod journal shows damage from the failed rod bearing.

What's more interesting is the #4 rod end which shows heavy bluing, a sign of severe overheating, even though the rod bearing and journal show very little if any damage (other than contamination from the #1 failed bearing).

It's also worth noting that all the main bearings show significant damage due to contamination from metal from the failed rod bearing, whereas the none of the rod bearings (other than the failed one) show much damage at all.

Hmm, the rod bearing disappeared, where'd it go? Oh, there it is–or what's…

Confession time, or, sharing my latest major screw-up

Written by vtluu on November 12th, 2014
Look at the diagram below. Now tell me how to torque the main crank bolt on the Mazdaspeed 3 L3 engine?

The correct interpretation is "torque to 100 +/- 4 Newton-meters (74 lb-ft), then tighten the bolt another 90 +/- 3 degrees."

Guess which part I suspect I overlooked?

This is a particularly lethal mistake to make on the L3 engine, which relies solely on bolt torque to hold the crank and cam timing chain sprockets in place–no keys, no pins. And it's an interference engine. Result: freshly-rebuilt engine toast.

I feel ambivalent about this

I totally agree with +Wil Wheaton about the problem, and I agree with his reasoning about how to solve it, however he seems to have overlooked or understated the protections that anonymity gives to the victims or potential victims… The whole +Google+ "real names" debacle did a lot to inform my understanding of all the legitimate reasons people have for anonymity, and I think a lot of the same reasons apply to online gaming as well.

Wil Wheaton: Anonymous trolls are destroying online games. Here’s how to stop them.
It’s time to name names.
