Quick-and-dirty symmetric encryption

Posted 01-27-2011 at 10:53 PM by anomie

Nothing earth shattering here. Just a quick automation utility I put together using the venerable openssl.

The wrapper script does a couple sanity checks, and saves you from having to remember command options for enc(1). You can change _cipher to suit your tastes / baked-in support.

Code:
#!/bin/sh

# $Id: encrypt,v 1.3 2011/01/28 04:38:22 anomie $

# NOTE -
# Save this script in your users' PATH as
#       "encrypt"

Updated my Dell GX1 PII server to Ubuntu 10.04 LTS. One or two of the old web apps are foobarred and need to be fixed. The apps I wrote still work though. The Firefly itunes sort of compatible streaming server still works. You can not live without music.

Updated my Wordpress blog (computothought.wordpress.com) with entries from an older blog. You spend any amount of time on a blog and it becomes a real body of work before you know it.

I've noticed a ton of complaining about PostgreSQL's apparent lack of sanity when it comes to index usage, so I'd like to throw a few things out that explain the "idiotic" way PostgreSQL handles indexes.

First things first. If the table fits in a single page, YOU ARE NOT GOING TO SEE INDEX ACTIVITY. That gets more people than any other issue. If the table has 17 rows, don't expect PostgreSQL to bother with indexes. Using an index on a table that fits in a single page...

They do not come because they do not care

Linux captured 2% of the desktop and is not moving anywhere despite all the Ubuntu efforts. It took me long time before I could formulate my understanding of the WHY.

Re: 2%. Some say it is 1% and the other say it is biased. Yet the other say it should be estimated at 5% based on indirect data. My impression is that whenever I run over something that looks both measured and unbiased in the Net, it is 2%. So, let it be 2%. The number does not matter much, what matters is that it is...

Was reading the rss where where I saw there was an article about using the parallel port. I had just done one. Decided to click on it to get more info. Low and behold it was my own unfinished instructable. Surprise, Surprise, Surprise. in sort of a Gomer Pyle way.
