[Apache AccessLog] %2f..%2f..%2f..%2fetc%2fhttpd%2flogs%2ferror.log

Recently reviewed the Apache Accesslog for one of the sites I'm handling.

Got a bunch of entries in my access log that looks like these - - [27/Nov/2013:13:27:58 +0800] "GET /wp-content/plugins/theia-post-slider/js/balupton-history.js/history.js?ver=..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2fetc%2fhttpd%2flogs%2ferror.log HTTP/1.1" 404 - "http://[this-is-intentionally-masked].com/" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; ScanToSecure)" or - - [27/Nov/2013:13:30:11 +0800] "GET /wp-content/plugins/sociable/css/sociable.css?ver=..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2fvar%2flog%2fapache%2ferror.log HTTP/1.1" 200 5687 "http://[this-is-intentionally-masked].com/" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; ScanToSecure)" Notice that the second example is actually a HTTP 200 OK status request.

Liquid Cooling using 3M™ Novec 7000

Liquid Cooling experiment by Corvalent Corp
From the video description:
This is a video of an engineering experiment we conducted cooling a computer by completely submerging it in liquid. This liquid submersion cooling system is NOT using mineral oil, or any type of oil cooling. This experiment was done using a chemical made by 3M called Novec™ 7000. It has a low boiling point, and leaves no residue or any trace whatsoever behind on the motherboard. The board was equipped with an i3 processor, running at 100% load. 
3M™ Novec™ 7000 Engineered  Fluid
The "magic" behind this is the 3M™ Novec™ 7000 Engineered  Fluid.

The liquid has low boiling point, low-toxicity, is 100% Ozone safe, and is used as heat transfer fluid for cooling reactors in pharmaceutical & chemical processing.

The best property about this liquid is because its non conductive, you can have total immersion cooling system.

No heat sink on all the chips. No water pump or radiator required at all.

The water c…

My Thoughts on The Volvo Truck Advertisement Series

I was quite amazed by the Volvo advertisements that gone viral on all social media. If you haven't watch the videos, scroll to the bottom of the post and watch 'em all.

I've learned that when you want to make a YouTube hit, you need the hook at the beginning of the film. And here it is.
I think the Volvo Truck advertisements were brilliantly executed.
