Playing with ISDN
As I work on the current big project at $work, I’m getting more exposure to ISDN (otherwise called It Still Does Nothing by my boss), and the tools used to diagnose ISDN connectivity issues. We’ve got a few bits of kit lying around here, including handsets that can emulate a PBX or monitor an ISDN […]
Long time no write.
Yeah, I’ve let things lapse a bit more than I normally do. New job has me quite occupied, and I had a house guest for the past month. House guest has now gone home, and I’m back to being a lazy bachelor. Yes, this means I need to do the dishes in the sink. Perhaps […]
I’m a twit

I’ve been doing speed tests to test the multiplexing of Yosemite’s Backup, and it was capping out at 600 – 650 MB/minute, even with 8 servers […]

Not really a problem, except out of the box, the (K)Ubuntu dhcp client (dhclient3) doesn’t actually support option 249 – classless-static-routes (or ms-classless-static-routes as some sites on the net refer to it). The format that the MS DCHP server spits out is the mask, followed by the subnet, […]
Dear brain, please pay attention.
So I’m sitting here working on a mid-sized array that defines permission flag names, and the default values for different types of user – I’ve dumped the array out after sorting it, and I’m re-importing it into the code so that I can find bits easier (alpha search by analogue eye). As I’m running a […]
Net::Server to the rescue
Some days, programming can be quite fun. Boss dropped a hot rock on the lap of myself and the other developer, saying that a customer (to be?) who had a bit of paper for us wouldn’t give us the paper until a certain feature offered by sales was done. Our task (and we didn’t get […]
