So the voltage drop is so rubbish, the utilities have to overcompensate...

To be clear, the voltage drop is not predominantly from too-small wiring, but from other appliances on the circuit drawing lots of power.

It's all relative. European 230V isn't even quite double the voltage of the US' ~125V, so you still get plenty of voltage drop, yourself. Someone else could come along and say 230V is rubbish, and everyone should have gone with 420V or so, when we both had the chance... Of course the US' lower voltage has the advantage in lesser risk of electrocution, too. The higher 60Hz frequency incidentally gave us better TV...

Even though the common NEMA outlets are 120V, and that's unlikely to ever change, the wall outlets don't need to for big loads... any house built in the past 50 years probably has 240V available at least the electric box, as they get 2 opposing phases of ~130V from the power company. Big appliances like electric stoves, electric water heaters, central air conditioning, and larger split-system heat pumps or large window air conditioning units, ALL are run on 240V here in the US.

Big industrial customers make up 75% of electrical demand, and they're different beasts all together. 277V (single-phase) is pretty common in US industry, particularly for lighting and what not, while big electric motors run on 3-phase 480V or so. Wherever higher voltages are beneficial, they're available.

rough service lights at designed to be handled roughly, and a heavier duty filament that is rated for a higher voltage allows it to be banged around a lot, not because you can hook it up closer to an electrical box

False dichotomy... it's designed for BOTH purposes.

The only time I've see > 125 V is when helping someone who bought a very cheap generator, that could easily have been out of spec for 240 too.

That's your own lack of perspective. I'm an EE, I went through the training and could get an electrician's licenses if I so desired. I do electrical work on my own properties pretty often. At work I'm primarily responsible for monitoring the incoming power for our hundreds of servers at our data centers and our office server rooms, etc., and designing and ordering upgrades as they are needed. I also have friends who are licensed and working electricians with lots of experience. etc.

I just tested the wall outlets in my nice new apartment, a good long distance from an electrical box, and I've got 124.1V everywhere right now. That's not abnormal at all, but completely typical.

I'm wondering WHY they're asking for permission. Seems ludicrous to do so when everyone's already giving it up for free. Making it legit?

They're collecting all that information, but they have to keep it under wraps. They have to get permission, like this, to be able to release (sell) all your vital information to 3rd parties.

The public and our representatives don't care about privacy, much. But after the free-for-all is on for a while, one case will break-through in the media... Something about a violent criminal buying the information from Verizon, using it to figure out exactly when little Jill comes home from school every day, and how long she's there by herself before her parents get home. When cases like that get publicized, then in a sudden tidal wave of popular think-of-the-children support, we get a bunch of privacy laws passed.

for soldiers one would expect long endurance would be a plus. Ultrarunning is something where men and women appear to compete on a somewhat even footing.

Women are nearly competitive with men at long-distance running only because of their lower weight. Once they are outfitted with 100lbs of gear (which firefighters and soldiers are), they suddenly and dramatically lose their parity with men.

Assuming that our DC sources of electricity are already somewhat efficient, why don't we just have other things that use that current be DC as well?

It's not AC vs DC. Somewhere along the way, your input voltage won't match your output voltage, and conversion is needed. That voltage conversion is where the expensive equipment and losses come in. Adding a DC to AC step in there, adds very nominal losses to above voltage conversion step.

Since the world standardized on AC power over a century ago, it's as good of an output option as any other.

resistance loss is a serious issue even for the short runs within a building - so you may still see 110V at the socket, even if it's supposed to be 120V.

Not true. You're vastly more likely to see 130V at a socket, than ever seeing one at or below 110V. That's the actual voltage delivered near the electrical box, dropping down to 125V or so, after it has been run across a building. Rough-service bulbs in the US are designed and rated for 130V instead of 120V for just this reason... A 120V incandescent light very near an electric box can have a rather short life-span.

if it is impractical to deploy a new codec in the field alongside the existing codecs, a first mover will win. This is why U.S. OTA digital television is stuck on DVD/SVCD era codecs, but some countries whose digital transition happened later use H.264.

It's not true that H.264 is significantly better than MPEG-2 video, when used at high bit rates as in HDTV. Every video codec developed since MPEG-2, and every audio codec developed since MPEG-1 Layer II, has been focused on low-bit rate video that needs to look good, but doesn't need to actually be identical to the original.

This is because the first-generation audio and video codecs already got quite close to the theoretical limits of perceptual entropy, so there is NO room to double the efficiency while still making it indistinguishable from the uncompressed original. There's still tons of headroom, however, to make something low bit rate that just looks "good" and comprehensible without obvious distracting artifacts.

The article mentions Youtube, without giving any specifics. Seems they're shipping the plugin greyed out, disabled etc. and then WebRTC stuff will work (does anyone have either used that?) and then maybe you'll be able to use html5 video in some future version, maybe.

You don't need H.264 for Youtube. You can watch everything there, and at several other sites using the "Video WithOut Flash" plugin:

It works pretty damn well.

The geek sees everything in terms of the "open" web.

But there is more to digital video than video distribution through the web.

The "distribution" is orthogonal to the codec being used. Most of the things that make a good "digital video" codec for the "web", also make it exceptionally good for physical media, dedicated hardware, etc., etc.

Which is why the mainstream commercial codecs dominate here.

No, MPEG codecs dominate, because they had NO open competitors, until *just now*.

VP3 was okay at the time, but it wasn't support by anything, Theora went nowhere for a DECADE and was awful compared to contemporary codecs, by the time they finalized their not-quite-VP3 format, and started pushing for adoption.

VP8 was a good codec, but it didn't get open sourced until LONG after H.264 had an overwhelmingly dominant installed base. The MPEG-LA also did their dammedest to threaten to sue anyone who used it, but now such challenges have been conclusively settled in court.

It's only just now, this year, that VP9 is being released for unencumbered use right about the same time as HEVC/H.265 came out. So it's only now that we'll see if the market is ready, willing, and able to adopt open formats.

So you have some perverse idea of what feminism is meant to be [...] (b) is your own invention in the first place.

Bullshit. I pulled the assertion straight from TFA. You can't blame me for it. Did YOU bother to read TFA?

From TFA:

"people think men and women receive the same harassment online. They do not."

"The Myth: Everyone in the games industry experiences harassment. Women are just too sensitive about it."

"If you are a woman in the industry with a critical opinion, you will get a disproportional amount of criticism, hostility, and scrutiny compared to men."

"male privilege makes them feel free to lash out."

You're insane.

I'm merely stating the logical conclusion of GP's self-justifications. What part of my statement is inaccurate? Of course demonizing anyone who disagrees with you is so much easier than honestly addressing the issues they bring up.

Women are seriously beaten and murdered at FAR LOWER rates than men. You seem to have a real problem with FACTS.

I'm supposed to walk around armed at all times (illegal here),

There's no territory in the world where it's illegal to carry a modest-size knife.

I never said anything of the sort. I simply said that you have options, and being deathly afraid of everyone is not necessary, nor is being physically small an excuse to get the world to cater to you.
