The Threadless Nut

A while ago we took the plunge, canceled our land line phone and switched to cell phones as our primary lines. While this has been a significant cost savings for us, there was one significant downside. You only get 1 phone. With a normal phone line you can scatter phones willy nilly about your evirons. One in the kitchen, one in the living room, one in the office, a couple in the bedroom, and, if you’re rich, one in each bathroom. Going to a cell phone means you only have the one, which you can carry around, but set it down and you do the inevitable race for the phone, if you were close enough to hear it playing your Rockford Files ringtone.

Enter the Xlink-BT.

This little gem wires into your existing phone system. You can either hook it up to the wiring, or just plug a multi-handset cordless phone into it, which is what we did. It then connects to your phone via bluetooth, just like your Borg headset. Just like that, you can use your home phones with your cell. It can connect to 3 cell phones at once, and each gets a distinctive ring, so you know whose phone it is. Once paired with your cell, it will automatically bond when you get in range. The cell phone handset is still enabled when it’s connected to the Xlink, so it won’t steal your calls like the headsets do.

I did have a few issues initially getting things working, but I downloaded new firmware from the Xlink site and updated the device and everything cleared up. The firmware application is Windows based, but it worked fine in a VMware image. As hard as it is to resist hooking up everything right away, I’d recommend getting the latest firmware first thing.

This is really a wonderful little piece of kit. It never causes any problems and just works transparently. You can leave your cell plugged into the charger and never have to worry about running out the door with a depleted battery and never have to go looking for the cell when a call comes in.

There is one complaint I can make. The name portion of the caller id is lost somewhere in the chain. So on your house phone you’ll see the proper number that is calling, but the name will always be “Xlink-BT”. It really is only a minor annoyance though, and I imagine there’s a good reason why they can’t make it work.

National Engineer’s Week is this week and I was asked to do a presentation on software engineering to about 40 local middle school students. I was a bit unsure how to approach this as it’s not the audience I’m used to dealing with. I’ve presented to rooms full of executives before, but I was more nervous about this. I’ll leave the obvious jokes about maturity levels as an exercise for the reader.

Now that it’s over, I’d say it went very well (thanks to advice from my lovely wife). I was last on the agenda, so the kids were a bit drained and antsy, but I managed to keep them occupied and interested. I had an activity planned in which some volunteers represented parts of a very simple program, a bubble sort. I had them physically act out the operation of the algorithm and when it was completed they could see the results (the volunteers were now in alphabetical order). They were actually enthusiastic about participating in this little exercise, which was probably my biggest fear. It would have gone much differently if I had to drag kids up, or bribe them with the M&Ms that a certain someone suggested I bring. It was inspiring to see some of the kids watch the process, expressing confusion as it wasn’t immediately obvious what was happening, but then as it progressed, they got what was going on. I think they really enjoyed it.

The blatant pandering of using a screenshot of Super Mario Galaxy and one of the Google map to their school actually resulted in cheers. So I’ll keep that in the toolbox for the future.

One thing that didn’t work was sarcasm. If you know me, you know how integral that is to my daily life and the kids mostly just didn’t get it. I guess I should have seen that up front, but at least some of the teachers got some chuckles out of it.

Overall, I really enjoyed the experience, the kids asked a lot of good questions, though several were about salary. I hope they all got something from it.

Here’s my presentation, if you’d like to see it.
