Get out of the gasoline mindset. I commute to work 5 days a week, 30 miles each way. I park my car in my garage every night. I fill up my tank about once every 8 days. It takes about 5-7 minutes each time.

With an electric car with a 200 mile range, I would still drive my car 60 miles a day, but I would no longer be stopping at a gas station every eight days. I would be plugging in every night. The only time I would ever need a charging station is when I need to drive more than 100 miles away from my house. I do this MAYBE once a month. So, already my demand at a 'fueling' station is 1/4 of what it was.

Add to this the difference in costs build a fueling station. A public level 2 charging station can be installed for as little as $5000. Level 3 would currently cost about $50,000. A charging station can be anywhere, and can be built in days. Charging station supply will be able to increase very easily as demand does. You can even put one in a school parking lot. The electrical infrastructure to deliver 'fuel' to just about any corner of the continent is already in place. Basically, you charge your car wherever you park it. A gas station is a destination.

Citation, please. Considering my 2012 VW GLI cost $26k new (plus tax and MV fees which you have to pay new or used), how am I overpaying a 'couple of 10s of thousands'? Considering the average price of a new car was $31k last year, I think you are way off base. Second, a car with 2/3 of its life remaining? What is that? 100k miles? 200k miles? We'll go by consumer reports, which says it's 8 years/150k miles. So you are claiming that you can buy my used GLI in 2015 with 50k miles on it for $8600 (forget the fact that Edmunds shows the private party resale value of my car as $17k), which has now lowered by cost of ownership down to less than $18,000. . I spent nothing else to maintain the car- even oil changes were included under the warranty.

I won't argue that over the long term, a gently used car costs less than a brand new car, but your numbers are way off base. I give value to a car that is pristine, and still under full manufacturer warranty.

Comment: When were you last a network engineer? (Score 1) 163

If you've been a network engineer in the past few years, you'd know exactly why you'd need to break SSL. Traffic prioritization used to just require looking at the TCP/UDP port- SMTP and FTP could be low priority, while HTTP was medium priority, and RTP was high priority. Then users started using non-standard ports, so you needed to look deeper- you start looking at the content-type header in HTTP. By doing this, you could still make the octet-stream and application-pdf low priority (file transfer) while the text/html would be higher priority and audio content-types the highest.

This was all well and good, but then the web moved to SSL. Not just for email or banking, but even sites like Youtube and Facebook. Now, QoS devices (which are critical in bandwidth limited situations like zooming across the sky near Mach 1 at 30k feet) need to peer deeper into the packets. In an enterprise environment, this is done the same way Gogo is doing it, except we control the list of trusted CA's on the computers, so we can tell our users to trust the (fake) certs that we are signing.

It's not a great solution- it's essentially a man-in-the-middle exploit. The better alternative would be for sites like Youtube to honestly set the DSCP header, but that's not going to happen...

I don't think you understand how amplification attacks work. Anti-spoofing measures don't do anything. The spoofed messages don't come into your network. The very large responses do. And by the time they reach your filters, the damage is done; they've already filled your pipes. As the patent said, it's not exposing a weakness on your system. It's exposing a weakness on third party DNS servers, and the hundreds/thousands/millions of peoples' PCs that have been controlled via botnet.

I agree for the most part. My torrenting has really dropped off in the past couple of years. Shows like Top Gear and Dr. Who, which used to be a year or more behind in the US (if they aired at all) are now only a week or so behind. Services like Netflix have much improved libraries of content, rather than just B-movie versions of good movies.

However, I still torrent for a couple of reasons- Streaming services are not compatible when I want to watch content while traveling. They generally don't allow an offline viewing mode.

The other thing I tend to do is torrent kids movies that I have on DVD. The DVD version has umpteen previews, ads, and (ironically) FBI warnings before the movie starts. I used to rip the DVD, but even once I figure out/update the tool that can get around the copy protection, it still takes longer to rip than it does to download the movie in .mkv format.

I'm a networking guy, so I'm more network-based, than server-based.

Mostly old data-center cast offs-
24U rack (48U cut in half to fit under my plumbing/duct work) in the basement
Cisco 3750-48 PoE Gig switch, providing direct connections to all of my first floor equipment.
Second floor equipment has a direct run to another 3750 switch upstairs. Too hard to run direct lines in an old house.
Bluecoat (nee Packeteer) Packetshaper 7500 for monitoring and QoS on Internet traffic
Cisco MCS 7825 re-purposed back to an HP server, running Ubuntu for any Linux server needs I have. Usually powered off to save power
Netgear WNDR3700 router running DD-WRT

For years, I had all email for my vanity domain forwarded to my gmail account, and gmail lets you send email out with the Reply-to header set as your vanity domain. It was only when I wanted some more advanced capabilities of Google Apps did I suck it up and start spending the $50/yr/user to fully port my domain over.

This is more worrying. The Comcast/twc merger is not really a merger of competitors. They generally serve separate and distinct markets. If I am unhappy with comcast, I cant switch to twc. But I can (generally) switch to directv or dish, or possibly at&t uverse or verizon fios.
