Here are the types of things my mind picked up on today that no one else on the face of the planet would notice, much less care about:

• mot.com (MOT is Motorola’s stock ticker) resolves to 192.168.0.110, a non-routable internal IP.
• Doing a traceroute from here to mot.com, it goes through six routers (four at school, two upstream) before they start dropping packets. Every single router, in my mind, should be checking for impossible conditions like that and dropping packets. But, if nothing else, our edge router should do this filtering, as should the first upstream router.
• One of Waltham’s firefighters transmits a sidetone when he keys up, in addition to his MDC data. This is a weird problem. (What’s supposed to happen is that the radio transmits a little data burst at the start of each transmission, identifying his radio. The exchange takes about 200ms, so, while the radio transmits this, it beeps at the user to indicate that they shouldn’t start talking yet. When it stops, it starts transmitting his audio.) In this case, the sidetone and data burst are both getting transmitted.
