Adsense and Blogging

As you might have noticed, I haven't been blogging very much lately. Today, I noticed a direct correlation between days I blogged and income from Adsense. It is about a 20% difference with a one day lag. Facinating.

Slurping files in Perl

Uri Guttman wrote just what I was looking for: a careful exposition of how to read files fast in Perl. Kudos.

Regular expressions and .NET

I enjoy Perl and PHP in large part because of support for regular expressions. Much can be done in a short amount of code. Guess what? It is firmly embedded in Microsoft .NET Framework. I had no idea. The classes are located in System.Text.RegularExpressions. A nice tutorial is can be found at Nice.

The "H" Rate make-up stamp

This has got to be one of life's little annoyances. How much is an "H" stamp worth and how much is the "H" Rate make-up stamp worth? Who can remember? For an interesting read, checkout Paul Rubin's note on the whole debaucle. He writes:

The current 1¢ stamp is green with a rooster and is labeled “The ‘H’ Rate make-up stamp.”
That's good to know. Now, is it still worth a cent? You can learn more about the alphabetical stamp at an intriguing site called "Alphabetilately". I found the answer to my questions there:
Stamp Value Date of rate change
A 15 cents 5/29/78
B 18 cents 3/22/81
C 20 cents 11/1/81 (!)
D 22 cents 2/17/85
E 25 cents 4/3/88
F 29 cents 2/3/91
... F makeup rate 4 cents  
G 32 cents 1/1/95
... G makeup rate 3 cents  
H 33 cents 1/10/99
... H makeup rate 1 cent  
(no I stamp) 34 cents 1/7/01
A postcard, by the way, costs 23 cents to mail.
