I’ve been working on a Presario SR2011WM. It’s a basic, low-end, single-core Celeron D system from 2006 or so. It can take up to 2 GB of RAM, runs Windows XP adequately, and has SATA ports, so you can put an SSD in it if you want. But don’t be fooled by the name–the Celeron [...]

How I once took down a network, including a radio station
I met up Monday night with some other security professionals for some emergency networking of the professional kind. One of the attendees, a penetration tester, had a little incident where he took down a production system when he conducted his penetration test. The system owners were a bit arrogant, and, well, they paid for it. [...]

Is this a good computer for the money in 2013?
My realtor sent me some computer specs this past week and asked for my opinion on it, since I get paid to keep up with this stuff these days and he doesn’t. I thought my critique of the system might help other people.

Why Intel can’t quit x86
Here’s a nice perspective on Intel’s non-x86 efforts, and why they failed and x86 marched on, despite its weak points. Kudos for remembering that Intel made ARM chips.

ARM exec says: $100 tablets are the key to mass adoption
This week, ARM said what several people seem to have figured out: The key to mass adoption for smartphones and tablets is the $100 price point. It may happen this year. It’s not hard to find a decently fast $80 Android tablet, but you’ll have to put up with a sub-optimal screen to get it–800×480.

Stopping spambots cold with Botblocker
I’ve been absolutely getting pounded lately with spam comments from spambots–to the tune of one spam comment per minute. That’s filling up and slowing down my database and consuming CPU resources that I want for human readers. So I resorted to installing Botblocker. All I can report right now is that it seems to be [...]

Up and coming low-end Android chips
I decided to dig into what the low-end Android chipmakers like Mediatek and Rockchip are up to, since they’re the ones who are likely to drive prices down.

Four simple steps to optimize WordPress
A couple of years ago, I stood up a WordPress server. I made no effort to tune it, let alone turbocharge it, which is a decision I later came to regret. If your site gets more than a few hundred hits per day, you need to tune it. If you want to get more than [...]
