Sever Scam

The Scammiest Scam To Yet Anonymity Scam

I'm still holding out for this being a hoax, a big joke, and that they're going to cancel the kickstarter any minute. It'd be quite the cute "lessons learned" about anonymity scams. However, I will be treating it from here on out as a genuine scam. (As of May 2nd, the kickstarter has been cancelled, after the strangest attempt to reply to this imaginable. Good riddance.)

This absolutely ridiculous thing was brought to my attention by a friend and since it was late at night I thought I must be delirious in how absurdly over the top fake it seemed. So I slept on it, woke up, and found that it had gotten a thousand dollars more funding and was every bit as flabbergasting as I thought it was.

Since I realize that not everyone has spent their entire lives studying computers – and such people are the targets of such scams –

# Python script to find the largest files in a git repository.
# The general method is based on the script in this blog post:
# http://stubbisms.wordpress.com/2009/07/10/git-script-to-show-largest-pack-objects-and-trim-your-waist-line/

# The above script worked for me, but was very slow on my 11GB repository. This version has a bunch
# of changes to speed things up to a more reasonable time. It takes less than a minute on repos with 250K objects.

The keystore password on Java keystore files is utterly pointless. You can reset it without knowing it, as shown by this code. Note that private keys are still secure, as far as I know. The JKS implementation is copyright Casey Marshall (rsdio@metastatic.org), and the original source is available at http://metastatic.org/source/JKS.java. I've in…

Routing tips for VPNs on OS X

Routing tips for VPNs on OS X

When VPNs Just Work™, they're a fantastic way of allowing access to a private network from remote locations. When they don't work it can be an experience in frustration. I've had situations where I can connect to a VPN from my Mac, but various networking situations cause routing conflicts. Here are a couple of cases and how I've been able to get around them.

Specific cases

Case 1: conflicting additional routes.

In this example the VPN we are connecting to has a subnet that does not conflict with our local IP, but has additional routes that conflict in some way with our local network's routing. In my example the remote subnet is 10.0.x.0/24, my local subnet is 10.0.y.0/24, and the conflicting route is 10.0.0.0/8. Without the later route, I can't access all hosts on the VPN without manually adding the route after connecting to the VPN:
