Just imagine being DDOS-ed by a bunch of home appliances!

Agree...this is exactly where we are going with this home automation non-sense

Yes, code is sometimes bug-free, and for certain safety-critical applications absolute proof of correctness is mandated by law.  But it takes unwavering design discipline, which is expensive and slow, and the functionality has to be kept simple enough so that it can be completely understood down to the bits-and-bytes level.  And when it's proven correct, it needs to be burned into ROM so that it can never be changed.  In addition, the hardware it executes on has to be proven formally correct.  Can't do it with mayfly parts.

Anybody other than me look at those shiny stainless steel refrigerators and hear the "Terminators" theme music in their head?

And, in Ah-nold's voice, "Your milk is bad.  A$$hole."

Exactly what we don't need. Hopefully this fad will pass soon enough. Do we really need to know that the fridge was opened 10 times in the last 24 hours?

The IoT will be spamming everyone and everything. There will be security flaws (is code ever bug free- NO!) so hackers will probably be able to turn every kitchen appliance into a malware bot. Just great...

Updating the Internet of Things
DrQuine   4/2/2014 5:44:47 PM
Having a computer that receives security updates is bad enough. When every device in the house is getting updated (many of which we may not even be aware of), we may find ourselves in gridlock. Already a quick attempt to check something on the Internet is frequently blocked by a mandatory automated browser reboot and software installation at the worst possible time. Turning off the updates is even worse; many website then refuse admission because I'm running obsolete browser software. I also find that automatic sensors (like the oil level in my home heating tank) seem to do their daily transmission a minute after the vendor does their daily system update so the information is always running a day behind (and worse on weekends). The basic process flows and dependencies need to be worked out and hardened before we find ourselves in the hell of electronic device gridlock.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
