"I've had this nagging feeling that the computers I use today feel slower than the computers I used as a kid. As a rule, I don’t trust this kind of feeling because human perception has been shown to be unreliable in empirical studies, so I carried around a high-speed camera and measured the response latency of devices I’ve run into in the past few months. Here are the results:"
A really cool read.
I recently wanted to put a Gates HD belt in my C5 Corvette. Standard LS1, with a Magnuson MP112 unit sitting on top, and an ECS tensioner which shouldn't actually make a difference but who knows.
The standard belt recommended for the application is: K061045, or 6PK2652; size is 13/16" x 105" outer circumference, or 20mm x 2666mm outer circumference, 6-rib.
There's no Gates HD belt with that precise size. I can however confirm that the Gates K061058HD does fit properly. The length difference is within spec for what the tensioner will allow.
Bonus fact: the AC belt is a confirmed fit as well: Gates K040420 Multi V-Groove Belt. It's not an HD belt, but it's plug and play.
I wanted to get some movies onto my iphone without itunes, largely because I run linux at home. There are various ways proposed online - the most common being to mount the iphone as a storage device - but there's a very, very easy way: VLC.
- Download VLC from the iOS app store
- Get the device onto the same wifi network as your computer
- Open up VLC on the device, click the menu icon, and click wifi sharing.
- On the computer, use a browser to navigate to the shown IP address.
- Click the upload button, upload the videos you want.
That's it. Super easy, took a few minutes. Works on any major OS!
Today I learned something cool:

hier - description of the file system hierarchy
DESCRIPTION
A typical Linux system has, among others, the following directories:
/ This is the root directory. This is where the whole tree
starts.
/bin This directory contains executable programs which are needed in
single user mode and to bring the system up or repair it.
/boot Contains static files for the boot loader. This directory holds
only the files which are needed during the boot process. The
map installer and configuration files should go to /sbin and
/etc.
...etc...

There was an old much-referenced page about octane boosters, originally found at: http://www.idavette.net/hib/fuel/index.htm
In case that doesn't work, data copied here for posterity after the jump.
As far as I can tell, as of
3/28/18, the author of the TechCrunch article:
- Did not cite the original article published for years ago on blog.bolt.io.
- Works at the same company (Bolt Venture Capital) as the author of the original article.
- Copied the headline of the original article.
I suspect that had I turned in such an article back in school, I would have been in a world of hurt.
Recently, my vacuum-actuator for the supercharger's bypass valve stopped working (stopped holding vacuum, basically), resulting in the SC never being properly bypassed.
I have the 5th gen (intercooled) MP112 Magnuson supercharger on my LS1 engine (and I imagine, for the sake of SEO, that it's the same setup that goes onto the LS6 and other LS engines, among others.)
The resulting rattle and other issues were annoying - if you have an MP112 and you start hearing a metallic rattle at idle, observe whether the bypass actuator's metal ... hook-pole thing ... that pulls down the bypass valve is the thing that's rattling against said bypass valve.
You can also easily tell if it's not working by opening the hood while idling. With the throttle plate nearly closed, the engine should be pulling a high vacuum, and this should be pulling the actuator down, so that the SC is in bypass mode. If it doesn't immediately pull down when the engine is started, get a new actuator.
Their website is pretty hard to follow, but apparently the right part number is 45-00-13-113, and on their (fairly poorly formatted) website, it is listed as the actuator for the 4th gen. Well, they confirmed it was the right component for my car, sent it over (at a cost of about $150 with taxes and shipping) and it fits fine and solves the issue.
I found the following three links very useful when figuring out wheel sizes and tire profiles:
While bolt patterns specify which tires can bolt up to your wheel hub, there's a lot more to it - after the jump:
