2. You do not need to "consult a lawyer" to know what is legal and illegal.

Really? You have every law ever written memorized and every prescident ever ruled on? And you did this without 4 years in law school and 10 more years researching? That is impressive. More likely you are just extremely naive.

How and what you do is more often than not legal or illegal depending on how it is applied and where. No way in hell could any programmer writing code ever do anything productive if we had to research the ramifications of every change we are told to make and try to apply it to every jurisdiction on the planet and then write a 100 page paper outlining all the ways in which such change could possibly be used for "evil".

But since I have you here, and you are such a law expert, which LAW exactly is it that you believe that Vizio broke by sending back telemetry on it's application usage? Just to make it simple, I'll let you assume the jurisdiction is the United States.

Comment Re:Web apps have become more dynamic (Score 1) 85

Sorry, I should have just said this at the start, but HTTPS encryption, not including the set-up handshake (which isn't insignificant), and using a modern cypher, like AES will eat up around 2.5 cores by itself if your data rate is ~1gb/s (and we would exceed that at peak hours). Considering the webserver we had was only a quad-core, that would have been 62.5% of the available CPU time just for HTTPS encryption, or tripling our server costs (and/or the added complexity of requiring converting to a web farm).

Comment Re:Web apps have become more dynamic (Score 1) 85

With more server-side processing for each page view, the fraction of server CPU time devoted to actually sending the resource to the PC has diminished.

Perhaps it's the sites that you've worked on, but there a vast number that does very little actual per-request dynamic server-side processing. That's pretty much the very first thing you do in creating a scalable website is isolate that from all the other content. Just as an example, the last major site I worked on, all content was cached, and the cache was only invalidated on actual changes, so it was fairly common for only 1 request out of ~1 million to really ever do any server side processing. It wasn't a small site either, at it's peak, it would have 10k concurrent users with pretty rich media assets, so tacking on https encryption overhead to that would have killed the server.

And yes, the site had javascript, and "single pixel" images as well. And it all ran off a single server (well, 1 web server), and it ran well that way.

Comment Re:HTTPS negotiation was never the "slow" part (Score 0, Troll) 85

Then you've never tried to have a server actually scale in the past. The HTTPS negotiation was slower than HTTP, but the actual encryption took valuable server compute resources, and would cause many servers to belly up long before they should. Servers have gotten faster, and the the methods used to do the encryption have gotten a lot better, but if you think it doesn't affect how much a server can scale then you'd be mistaken.

There are solutions today, but none are free, and most aren't "simple".

Comment Re:AT&T -- pushing away their loyal customers (Score 2, Insightful) 58

I was on the grandfathered plan but when you realize that the "Unlimited" plan is really just a 2GB or 3GB plan (they've changed it a couple times), and then throttling down to EDGE speeds the other plans are just cheaper, since this is what their other plans do as well. And "free" unlimited texting (a $20 add-on to the grandfathered plan). And you can hotspot. And unlimited voice. And you can add additional phones for pretty cheap.

There really is no reason to hang on to those grandfathered plans unless you don't text (pretty much at all), or you expect some day the FCC will force AT&T to unthrottle the unlimited plans, and you never need to hotspot.

wolfcrow made a mistake in that blog, of which was pointed out a few times in the comments. A 50" TV seated 6' away @2k only has a dpi of ~38dpi, well shy of the 100dpi required. A 65" TV seated 6' away @4k still only has 67dpi. A 65" TV seated 6' way @8k has 135dpi, which based on his calculations done correctly, would be indistinguishable. Of course that still makes a number of assumptions, like you have average eye sight, and you are sitting 6' away from your TV, eye sight towards the center of the eye isn't more precise (which it is), and your eye can only resolve 0.4arc min, which on his complimentary blog article, two independent sources say 0.2 arc min.
