A CME is not an EMP event.

CME are dangerous because the stream of charged particles interacts with Earth's magnetosphere. The interaction causes the magnetic field to vary, and the changing magnetic field as everyone knows results in induced currents. Earth's magnetic field is weak, but the charged particles cause it to vary, and because of the variance, long lines (like power transmission lines) are the ones most affected.

Or telegraph lines, where the operators suddenly get shocked when the induced currents cause a large potential difference to build up (voltages of 50+V during the Carrington event).

Now, the problem is that the grid has enough circuit breakers to actually handle this - they're sensitive enough that disruptions will cause them to open. The issue is that once you start having grids, loads and generators islanding themselves, it causes further disruption down the line. Like the blackout of 2003 where one power generating plant caused the whole east coast to lose power for 3 days.

Having the grid shut down - it might actually be difficult to restart it since it's never happened before.

Same effect. The time to do it is not when the person who can make your life miserable still has power over you. And to treat every tweet as if you said it aloud right then and there - if your target is right there, don't assume they won't hear about it.

Hell, perhaps the other side isn't so rosy either - we just hear this guy bitching. How would he like it if she tweeted "just met the most demanding self-entitled asshole for a customer" at the same time?

Personally, I like the people who don't understand the difference between Reply and Reply All. When HR sends a company picnic invitation to Everybody, the invitation is immediately followed by a Reply All flood of RSVPs from that crowd. Lately, though, HR seems to have discovered the Bcc: field as a solution to that issue.

Well, given the default to most company emails requires reply-all, it's not a surprise, really. I mean, if you're on a project and you need to send information to others, you probably will put in several people. And the recipient probably uses reply-all so everyone can be aware of the followup as well. Because things get awfully stilted if everyone merely replied to the original sender and they get flooded with dozens of the same question and notes.

So it's natural in a business setting to use reply-all since you expect to share with everyone else. Hitting reply just feels unnatural.

And yes, that's what the BCC field is for, if you really need to break the reply-all chain.

I'd love to see a single UI that works across 4" phones and 7" tablets with gorilla glass, and 13" laptops and 10" convertibles with membrane keyboards, and 24" desktops with 101-keyboards, and 60" XBox Ones with controllers but I'm not holding my breath.

I don't think that's even possible because you'd compromise on the UI. Keyboard/mice, controllers and touchscreens have their own special qualities and interactions. A keyboard and mouse is a very precise pointing and data entry device, while a touchscreen is coarser but is able to provide multiple spots (multitouch) for gesture recognition that's far richer and easier to do than trying to use a keyboard/mouse. And a controller makes a poor mouse, but is killer at navigating in cardinal directions, with a few command hotkeys (buttons) for performing various actions.

Even worse, an app designed for one UI interaction works poorly in another UI interaction. About the only compromise possible is that one particular device may employ multiple interactions - e.g. a device with a keyboard/mouse might also have a touchscreen and a controller. But swapping between them is often a pain on the user.

Often the only way to solve the UI problem is to make each UI incompatible - so if you have a touchscreen device, interacting with it requires using a different API set so you can use it as an opportunity to redesign the UI to be more appropriate. Like how Apple redesigned OS X to turn it into iOS so apps have to use a different API to handle touchscreen events.

It also still doesn't give anyone permission to generate their own h.264 video files (outside of webrtc "video-chatting" inside the browser) legally without paying someone a patent "poll-tax" for permission, so this is still "consume-only".
I'm also under the impression that there are,absurdly, potential patent-license issues with the .mp4 file format that h.264 video is most often stored in.

Finally, of course unless the usual obstructionist Apple and Microsoft ever implement opus codec support, this also doesn't give you the legal ability to include sound (mp3 or aac, typically, for h.264 videos) with the video. Hope everybody likes silent movies...

If you have a camcorder, the license to create h.264 is present as part of the camcorder. This includes phones and everything else people submit to YouTube, for example.

The only constraint is that if you post content online, you cannot take payment on the content itself - i.e., you can put it online, you can put ads around it, but you cannot force someone to pay to view that content (commercial activity). So those videos on YouTube where you have to pay in order to view them come under a different license.

As for the Mp4 format being patented - it's RAND by Apple ages ago (MP4 is a subset of the QuickTime MOV format). If Apple's asserting any patents on the format, that is. But since people mass-license the h.264 patents through the MPEG-LA, that means any patents Apple has on MP4 are included in the license fee you pay to create or display the content.

Sound is licensed under a separate agreement - MP3 or AAC. Again, your typical MPEG-LA license for h.264 will probably include use licenses for AAC (most typical format) so you can have a soundtrack.

If not, there's always PCM as well - handled by the format just fine.

Well, it's utterly possible that Amazon pre-emptively chose to license the patent. But unlikely.

Because it's a design patent. Which aren't really patents in the normal sense. A "normal" patent is a utility patent - it describes a machine that does something that usefully transforms part A to part B by some series of processes.

A design patent covers aspects of the non-utility parts of a device - a pattern, a design, stuff that is there for aesthetic purposes than for utility.

In the case of the rounded rectangles, the device In question must not only have rounded rectangular case, but also a grid of icons with a smaller subgrid of icons along an edge. The main grid lets you page through it while the subgrid remains static.

Samsung got in trouble because TouchWiz emulated exactly that, while everyone else used the standard Android home screen (which fails because it's not a grid of icons when you have widgets, and the grid of icons (app launcher) doesn't have the subgrid).

In effect, Google worked around the patent.

Bah, just use the chassis as return; the frames might only be steel, but there's a good amount of it. That and I suggest 600V for truly limiting the amount of power lost through cables. ;)

You'd end up with servers welded to the rack.

Power losses increase with the square of the current - going from 5A to 10A means your cable losses quadruple. These are known as IIR losses (or I^2R losses).

Steel (iron) is an OK conductor of electricity - not great, but OK, so you'd have large losses of energy from the chassis itself (if you thought your racks were hot, well, now imagine the rack itself emitting heat!).

And unless the servers are contacted on practically every surface evenly, point-heating will take place that will weld the chassis to the server.

In fact, that's how an electrical welder works - a low-voltage high current source is all you need. Pass that current through a steel rod and it'll heat up and melt. (You want high current - voltage doesn't really matter - IIR remember? Double the current, quadruple the power).

Heck, it's a nifty physics demonstration when you take a step down transformer that takes line voltage of 120V and step it to 1.2V - that can get you 100A easily (with only a 1A draw at the other end) and that's sufficient for a demonstration. Remember, in welding, you're really creating a dead short.

it's why big racks often do get 208V, 240V or more into them - it's much easier to use thinner cables.

Except it requires more wires. 220/240V split phase requires 3 wires.

3-phase generally requires 4.

And unless you really need 3-phase, split phase is easier to deal with - with 3-phase you need to monitor all three phases to ensure they are working (failure of one phase is a common failure mode that requires immediate shutdown of the other two phases lest any dangerous currents develop).

Though, one thing I don't get about this challenge - they're using they want 2kVA output, but then demanding 50W/in^3 with a max size of 40in^3, meaning you have to provide 2000W.

And 2000W can mean providing way more than 2000VA. (The reason we use VA for inverters instead of watts is VA captures virtual power. 2000VA requires just as much power handling components (transformers, transistors, etc) as supplying 2000W at a 1.0PF (i.e., all resistive). Even if you have a really bad power factor and your real power draw is only 1000W - the hardware has to be able to instanteously supply the current and voltage for 2000W at periods in the cycle. The virtual power is virtual, because it's "given back" during another part of the cycle, but that means all the equipment has to handle it.

A lot of electric companies will have a power factor surcharge because of it - if your power factor can't be corrected to within limits, they charge more because they have to install bigger equipment.

The only real saving grace is that the input voltage is 450VDC, so you're really just doing a buck converter.

Not what this guy is saying is wrong, but there are other unaddressed issues. They cover issues like "power savings", but not the much more important issue of buying an unknown piece of hardware from an unknown vendor, without a warranty. Aside from that, sometimes there are issues of physical constraints-- like I have limited space, limited ventilation, and one UPS to supply power. Do I want to buy 5 servers, or one powerful one? ...

And sometimes, buying "new" is more about getting a known quantity with support, rather than wagering on a crap-shoot.

And that is the main reason why people buy new. To get the support contract because they know if the equipment goes down, they can start losing money fast. Sure they can do redundancy and stuff, and they often do, but they generally want both units to be under service contracts so when one fails and the other one is handling the load, the failed one is getting prompt service to minimize the likelihood of complete stoppage should the other fail.

I've seen perfectly functional equipment force-upgraded because the company making them stopped supporting it. Essential equipment like filers and such? They actually see end of complete support 6 months ahead and plan on migration way before the contract expires for good so they can revert to hardware still under support.

Running old servers is perfectly fine, especially for home use where the user can benefit from the low cost of what was very expensive equipment a few years ago. But until those companies are willing to provide support in case of failure that's better than "here's a spare, fix it yourself", well, there are very valid reasons to go with new. Even if new is barely an upgrade from the old.

Maybe it should. Providing an API and saying "it kinda work like this, most of the time, your mileage may vary" doesn't sound very good.

That already exists already - many formats specify practically subpixel accurate designs. E.g., PDF.

The thing is, HTML was never designed that way - it's a content-plus-format standard that says the content is marked up, and to provide some hints as to how to display it as the creator intended. But the user is free to override such choices as they see fit in case they don't have certain fonts, have display limitations, etc.

It's why ebooks generally use a limited form of HTML internally, and why most ebook readers display PDFs crappily. The reader wants to reformat the text to fit its screen better, but PDF isn't designed for that - it's design so one document can be displayed identically wherever you view it regardless of if the use has a font, has a 300/600/900/100 dpi printer, prints on A4 or Letter, etc.

Someone who will cheat for $6 can rationalize it by saying "everybody does this; it's only $6". In fact, the lower the amount, the less anyone would feel like they did something amoral. Which is exactly the opposite of what you implied.

And the rationalization the other way is "why cheat, it's only $6". As in, it's not worth the effort to cheat just to have $6. Now, $10k, that might be worth cheating for.

Basically balancing risk and reward - people don't rob banks much these days because the risk is high (security, cameras, etc), while rewards are low (typically $2-5000 each heist). However, rob a store and the rewards can be just as much, but the risk is often lower (less witnesses, older/crappier camera, practically nonexistent security).

it's just like there are people who will drive across town to save $0.10 on gas, while others simply don't bother as the time/gas/effort of doing so outweighs savings.
