Yes, Plex runs on Linux (and other OSes - I run my instance in Linux). It's slick.

The antennas haven't changed. Only the contents of the signals have changed.

In fact, old analog antennas still make great TV antennas, as long as your channels haven't shifted from VHF to UHF (as has happened in some markets). Even then the old antenna will still probably work well enough in many circumstances.

The advantage of the HDHomeRun solution, at least with Plex (if not with its own software) is that you get unencrypted feeds recorded on your hard disk. You can do what you want with them - you can generate DVDs or Blu-Ray discs from them, stream them, put them on a flash drive and share them... it's not trapped inside your box.

Diploma mills run like that, but not actual universities.

Putting 'cause, with the apostrophe like that, is informal, but perfectly grammatical.

Using cause for because without an apostrophe to indicate the missing syllable IS wrong, however. It's also frustrating because cause, as in cause and effect, is pronounced differently from the last syllable of because. I prefer "cuz" to "cause", but autocorrect has gotten rid of that, it seems.

Or, let's just all migrate to IPv6 and be done with this.

Most likely your player is bad. I've been using DVDs and Blu-Rays for nearly as long as both have existed and have never had a disk spontaneously fail. I certainly have had players fail though.

Greater lossy compression than you find for the video on Blu-Ray, and lossy compression on the audio (Blu-Rays generally have lossless audio).

MakeMKV + HandBrake (HandBrake can do almost all DVDs and some BluRays without MakeMKV, but MakeMKV is needed for some encrypted discs). MakeMKV is shareware (free beta period but reasonable to pay for if you don't want the hassle); HandBrake is open source. Both run on Linux, OS X and Windows.

This is from an Alix 2D3 which is (but not for much longer) my router.

He failed to argue that point.

Quite a few North American carriers use 2600 MHz (2.6 GHz) spectrum, although that doesn't change your point that much.

My mobile phone in 2001 was a TDMA (digital) phone. And that was 14 years ago.

And every aisle too. Not just on islands. :)

I think the problem here is that yes, you don't want to waste the time, but you (and few others) are willing to pay what it would really cost to offer fast airborne bandwidth.

A few Mbps are really quite adequate for 99% of the users that *need* in-air connectivity (or simply want it to prevent being bored, like me with IRC and web browsing). If people want to do heavy VNC work or video streaming on board aircraft, they're going to have to pay more than $20 for it. It's that simple.
