Lame SQL injection solution?

I dig campusfood.com; they enable internet orders from some places that otherwise wouldn’t do it, have a nice interface and all that… But, there’s this weird little quirk I just noticed. If you type parenthesis or quotes in the ‘notes’ field of an order item, they get scrubbed out. I’m guessing that’s some lame way to prevent SQL injection attacks… Given the overall quality of the site, you’d think they could be more sophisticated about that. Also, you’d think I’d have something better to do right now than complain about such a dumb thing on my blog for no reason. Just goes to show that anyone can be wrong…

ARP noise

(Not, like, this, though.)

I’ve recently become a Mediacom cable-modem user (in my new apartment, where it’s ‘free’). And my modem and router are talking to each other non-stop. Needless to say if you already knew it, I had to find out what the noise was about. Turns out the network is making about 20 ARP requests per second.

Ah, yeah, I remember this from the days when my DSL was in bridging mode rather than routing mode; gettin’ ARP requests for the whole damn city or something.

I guess it’s not a big deal, but it’s weird and annoying. I think I would have a network architecture that allowed me to filter these out before they went down the wrong pipe…

A test

If you don’t get this, you’re either slightly younger or slightly less geeky than me.
