Note to Self: Validate Input before using it in SQL Queries

Right, of course, I should be doing this already, but having magic quotes in PHP4 may hvae made me a bit lazy in some instances, and just like I’ve been going through and fixing register_globals dependence… As I read here, Both register_globals and Magic Quotes were implemented in PHP to help beginners who were learning [...]

Can You Really Upgrade WordPress in 5 Minutes?

5 minutes is a long time for upgrading WP, as far as I’m concerned.  I think it might have taken 5 minutes total to upgrade all three of my current WP installs and check/fix plugin issues.  Mind you, I use the subversion method of upgrading.  If you have shell access and can run subversion, it [...]

Matt (yes, that Matt) on WordPress Security

Even though the post title and first paragraph are about calling out a sound-and-fury-signifying-nothing alert, most of his post is good stuff on WordPress, with lots of links. … there is a wave of attacks going around targeting old WordPress blogs, particularly those on the 2.1 or 2.2 branch. They’re exploiting problems that have been [...]

Limitations of lj-stat

To the best of my knowledge and research, my LJ-code-base Site Statistics page (lj-stat) has the most comprehensive list of sites running off of LiveJournal’s codebase (if you know of any that I’ve missed, please let me know).  The main point, though, is the comparative statistics.  This is where things get strange.  LJ and most [...]

Using WordPress for User Authentication

Plenty of people seem to have written a lot about how to make WordPress use some other program’s user authentication mechanism, but there seems to be fairly little on how to get at WordPress’s user authentication from some other program.  Fortunately, I found this article, and got what I wanted. It’s a fairly straight-forward process.  [...]

Web Hosting

… or “How I learned to stop worrying and just sell my friends hosting.” I have many friends who aren’t particularly techie types.  Actually, I have very few techie friends.  And they all figure I’m the go-to guy for their tech questions.  Hence, I get asked to “help out” with setting up web sites now [...]

The Argument for a Mac

I have about as many WinXP machines as OS X machines around here (and a few OpenBSD boxes, but that’s beside the point), and yet I find it’s rare that I touch anything other than the Macs anymore.  Why?  Well, I suspect it’s the same reason I keep seeing little things here and there that [...]

CAPTCHAs

Recently (yesterday? today?), a hosting provider I inhereted when I took over a web site decided to add a CAPTCHA to their login page.  That is, every time I want to log in to their control panel, I have to do their CAPTCHA, which is one of the harder ones to read that I’ve seen.  [...]

Doing the Registrar Shuffle

Somehow, I get the feeling that I’ll be doing this more and more often over the next decade or two.  I’m just about done transferring my domains to GoDaddy.  This especially amuses me because for the past few years I’ve been with one of their reselling partners.  At the start, this partner was slightly cheaper [...]
