Metering lights are on during certain hours regardless of the flow of traffic. When traffic is going fast, they provide no benefit and actually make it worse by decreasing the merge speed of cars already half way down the ramp. When traffic is crawling, they also serve no purpose. They only help when the ramp is fed by a stoplight of tailgaters, and freeway traffic is heavy but flowing around 40-60 mph.

But they always increase emissions by bringing cars to an additional full stop and acceleration. Brake and tire dust emissions will also be significant during a full stop and acceleration.

The government in California is authorized by regulations to put up stoplights as a safety device. They are authorized to manage traffic. But they are not authorized to use stoplights to manage traffic, only as a safety device.

Many of our ramps are too short without metering lights. I wouldn’t be surprised if they actually decrease safety overall. There’s enough going on getting on the freeway safely at speed without having to follow a bunch of additional rules (there are many) while flooring the accelerator.

I’ve been ignoring the lights for about 10 years. If I have to stop because of a car in front of me, I will, but if one of the ramp lanes is open, I go. Sometimes this means passing a stopped car who’s following the rules, akin to cutting in line. I feel bad about it but I didn’t make them stop in the middle of an on ramp - a stupid light did.

Since you capitalized it, I suppose you’re referring to the writing of Henry David Thoreau? Maybe worth mentioning if somebody wants to read it. Dude sat in jail to oppose poll taxes. I don’t think it needs to be public or advertised but it should be overt.

For example I don’t stop for metering lights. Everybody can see when I do it. Sometimes nobody sees. But I don’t feel the regulation is just and so I must oppose it. I’m still waiting to get a ticket so I can challenge metering lights in court.

Btdig, not a tracker just searches DHT of other trackers

I looked into it a bit further and it seems the ATSC stream packets already contain built-in checksums! The interesting bit is that all the sub-channels are actually inter-mixed in one stream. So if you’re tuned to 13-1, your TV is reading and ignoring 13-2, 13-3 etc.

Unfortunately, I don’t know of any stream-correcting p2p network. I think it would start with a relatively open source tuner card. I think the tuner software is typically closed source, but it would be doing the work of reading the radio stream of a frequency and sending out an mpeg stream.

I wish there was good PoE hardware. I wish I had it for powered blinds, doorbell (real chimes), and even can lights which are now so poplar.

Kodi runs a server and a client. Depending on the client it may request a transcode. Looks like it’s just bad software support for h.265 on the client side.

Kodi played through the browser? It’s probably transcoding to H.264, using more bandwidth for lesser quality.

If your web browser can play it once, it can play it any number of times. Look into Widevine decryption. Basically you load the video in a special browser, save both the video and decryption keys, then decrypt the video file.

That’s a name I haven’t heard in a very long time.

It’s quite remarkable really. A single layer DVD stores 4.7 GB, for a movie with 576p (H.262). A while later those videos could be compressed using DivX or Xvid (H.263) down to 700 MB to fit on a standard CD, though full quality was more like 2 GB.

The Blu-ray standard came along with 25 GB per layer, and 1080p video, stored in H.262 or H.264.

Discs encoded in MPEG-2 video typically limit content producers to around two hours of high-definition content on a single-layer (25 GB) BD-ROM. The more-advanced video formats (VC-1 and MPEG-4 AVC) typically achieve a video run time twice that of MPEG-2, with comparable quality. MPEG-2, however, does have the advantage that it is available without licensing costs, as all MPEG-2 patents have expired.

Now H.265 is now even smaller than H.264, so now you could record a full 1080p movie onto a 4.7 GB DVD. Now the Ultra HD Blu-ray Discs are only slightly larger (33 GB per layer), but they store 4K video by supporting H.265 codec. I guess by now a 720p video encoded to H.265 could make a decent copy on a 700 MB CD.

I wish there was a good option. It’s actually legal to re-broadcast an over the air signal, provided it’s not altered in any way (re-encoded).

There should be a live torrent system for OTA TV. Antenna owners could use it to ensure perfect signal. The stream could be divided up by key frames and hashed (as bit torrent is). Any antenna owner would compare their hash to others to check if it was properly received. If not, that chunk could be downloaded instead of using the signal.

Such a system would make it easy to extend to leechers. They could offer a service to the antenna owners: hard disk space. The leechers are the ones who allow DVR service to the antenna owners.

Everybody wins. Antenna owners get perfect signal and they can pause and fast forward through commercials. Leechers get to view the live program without an antenna, and store the stream to repair antenna-owner broadcasts.
