Side Projects…

I built PC’s back in the 80’s, then stopped for some reason. Here’s what happens when I got back into it…

Losing the cloud… (Part 1)

There’s a Dilbert comic strip that I found hilarious a while back… The hilarious part is there is that the chance of this happening in real life is non-zero.  Not that it is likely to happen, but it’s impossible, statistically speaking, to completely rule out the idea. Now there are “big” cloud providers like AWS …

Slowly Draining Away…

Plumbers define a slow drain as one in which your teenage-kid has tried to wash clump of hair vaguely resembling a tribble down. Ed Mazurek from Cisco TAC defines it quite differently: …When there are slow devices attached to the fabric, the end devices do not accept the frames at the configured or negotiated rate. …

Recovering from a windows AD failure…

A couple of years ago my PDC died.  The only physical box in my environment and the one physical server died. I was 2,700 miles away.  I wasn’t going to be back any time soon, and stuff was broken.  (Thankfully, customer data was on the Linux Webhosting environment, so nothing lost there, except their backups) …

Oops. Not …

Quick note…

It’s cold in this data center. I went to stand behind the IBM XIV to stay warm.  I actually had to stand 5′ from the box to keep from being uncomfortably HOT. Just an observation…

Security Quick Note

I think that every network security department operates under the following motto: “If you can do you’re job, we’re not doing ours.” The customer I’m with has instituted a massively long password scheme. Now I’m not going into details, because that would be telling and would give even the greenest of hackers enough to walk …

Dear QLogic…

Here’s a note. If youre hardware has a driver that requires you compile it before use, and that can’t be easily upgraded. Your hardware isn’t ready for prime-time. It’s why I like Emulex. You plug it in and it works. You upgrade the driver with rpm and it works. You used to have great stuff. …
