> * Which EAP? EAP-TLS? EAP-MD5? [0] EAP-MSCHAPv2? Or perhaps EAP-GTC? EAP-TLS ideally. You need a CA infrastructure, a radius server, and a way of doing automated enrolment, revocation and install of client certificates. A lot of work if you haven't already got those parts (though many places already do), but it's fairly hassle free and secure once up and running. For bonus points you can extend 802.11x goodness to…

So, I'm fairly new to this... how would you do automated installation of client certs on: * OS X machines * Android devices * A Nest Thermostat > For bonus points you can extend 802.11x goodness to your wired desktop ports as well. Though, that only works if you have either a Smart or a Managed switch that understands that it needs to tag frames from that port with RADIUS-dictated VLAN tags, right?

OS X - puppet/chef or equivalent

Android - MDM (I think the stock google apps MDM can do client Certs and 802.11x network config)

Nest - would not bother; stick on a dedicated standard WPA2 network, segregate from rest of network then leave well alone.

Wired network - yes, you'd need a managed L2 switch (but then you'd need that anyway to trunk multiple tagged vlans to your APs).

> Although I had set the thermostat to 70 degrees overnight, my wife and I were woken by a crying baby at 4 a.m. The thermometer in his room read 64 degrees, and the Nest was off. This seems quite strange to me. Here in Germany it's extremely common to (automatically) turn of heating all together in the night (called Nachtabsenkung). One reason is to save energy, but lower temperatures also help sleep: http://www.nyt…

we keep ours at 70 just due to small kids that don't have big blankets or understand you have to be under layers at night

My 3 year old kid uses a thick winter pyjama. It solves the problem very well.

my a/c bill in AZ would be about $400-500 / mo higher in the summer if they made that move! Most people in AZ put their A/C to 87 or so if they aren't home and actually keep it in the high 70s even when home. Otherwise you're looking at $1K/mo energy bills in the summer

Turn off heat != turn on AC.

reasonable point ;)

For a measurement device, "accurate" and "reliable" aren't binary conditions, they're continuums. Not every sensor in the world has to be medical grade. There are plenty of applications where a less accurate sensor at a much lower price point is the right choice. Remember, I'm talking about situations where the company actually says "not for medical/diagnostic use". They're not trying to get away with selling lemons.…

That's technically fair, but everyone knows it's not what's going there. A small LED equivalent of a heart rate monitor is your optical mouse hacked into being a crude pulse oximeter. By the way, you know your mouse is also a 1-D camera / scanner, and can be used to somewhat digitize something? They totally advertise it as a working heart rate monitor. If they have a problem with accuracy, they should not be making i…

On a totally unrelated note, the image sensors in optical mice are actually low-resolution (16x16) 2D arrays.
