I don't really understand what this article says, but it came up during a search of "n-dimensional nolan chart". A Nolan Chart is the diagram that libertarians use to try to convince you to join their party/movement. They seem to worship the chart, but it's kind of absurd: you can label the axes with any two qualities, and map all people along two axes. You can also make a "chart" in any number of dimensions. In democratic politics, you always measure all dimensions, but ultimately, the system is set up around voting, so all dimensions ultimately collapse along one dimension: the vote.
This isn't addressed to anyone in particular, but it's a common question: does software get old and wear out. They ask because their computers have gotten slower, or features have stopped working.
A ten second calculation to deter comment spam. It's an old technique called "hash cash" and has nothing to do with drugs.
MySQL on my server is fading out more often than in the past. i wonder what's up.
This is interesting. These headers are from an email I got. It passed through someone else's Barracuda Networks anti-spam appliance (starting at $700, plus annual fees).
Identicons are those odd graphics you see next to peoples' names in comments. http://en.wikipedia.org/wiki/Identicon
[Turns out there's a PECL extension for tainting: http://www.php.net/manual/en/book.taint.php
It's hard to concentrate when you're tired and cranky, so I wasted some time writing a simple calculator in several different languages.
The telephone number that will tell you the number you're calling from is called an Automatic Number Announcement Circuit, or ANAC.
The IRS has a general sales tax deduction calculator. It helps you take the deduction even if you didn't keep receipts!
Here's a VBA script that I'm using to train Spamassassin from Outlook. It saves out email messages to a file server where messages are used to train the filter. The problem here is that Outlook doesn't save EML (MIME format) files. You can save messages as text, but lately, spammers have been loading messages with a lot of chaff text that looks like regular email. You can't train with that, because it might cause the filter to start mis-identifying legit email as spam.
I bought this several months back, and finally installed it on the Linux box. It works, sort of. ATSC (HDTV terrestrial broadcast) works fine. FM Radio does not. More info:
This post isn't for any specific reason, but it's been bouncing around in my mind for a long time. That higher levels of abstration is a "good thing" is given among experience hackers, people into functional programming, and people who write SQL. At least up to a few years ago, there was some hostility toward increasing abstraction, particularly from the anti-SQL set. I railed about this against and entry in a Symfony book. This is another review of the issue.
This is an outline I'm going to use to fix up a mass email script for Outlook that I'm working on.
