I work in commercial electrical power. No they don't. Because they aren't required to. It's all about costs. So unless it's about known risks (read PRA), no they don't protect against it. You need to spend money where the risks happen.

Wish I had better news, but hey you protect against "real" risks, like LOOPs, trips, downed trees, lightning, regulators, and floods. Well I guess the quotes are unfair, these things happen often. So these are real things you want to mitigate. End of the world stuff, no one takes that seriously sadly.

Also, don't forget a lot of the protective relays are digital protective relays. So even if you have them, well they might not work in This case. So aside from the digital PRs being "better" companies still sell them and few sell the older SD models, so we end up replacing the old solid state relays with digital drop in ones.

So even if you have a PR it might not work in this case. And frankly few people in the industry, or with the regulators, takes a geostorm seriously in commercial power, even though they should.
This makes me wonder: In 50, 100, 1000 years, what will be the state of studying computer languages from the present? Surely many of them will be gone by then (although probably not C), but some programs may still exist written in them. Or, some future archaeologist may recover a bag of servers and attempt to understand what they do.

Will courses teach old languages like they teach Latin and Greek now? Centuries from now, we may need people to decipher old computer programs just like old texts.

Or, perhaps all the documentation will be preserved and there will be little need to study the old languages beyond their primary docs.

As per the comments on the article Peter Klein has done work on this.

Market forces give prices which allow sensible and efficient economic calculation. When a firm is large and creates unique intermediate products/capital and performs intermediate services, it becomes difficult to tell if they are being done in an efficient manner because these things have no prices.
I wonder if they are using or would consider using blood plasma from Ebola survivors to help people survive. See this article:

http://jid.oxfordjournals.org/content/179/Supplement_1/S18.f...

There is more of a critical mass of recent Ebola survivors than ever before in history.

I know cultural fears can make it difficult to provide plasma transfusions, but this story is about a doctor who has Ebola. He almost certainly understands the science, and this could give him more of a fighting chance and a chance to show that medicine can help.

The state of California spent $500 million on the bike path for the new eastern span of the SF bay bridge. And probably significantly less preparing for threats like this one.
I must admit that I have a pretty high degree of confidence that if the director of NASA briefs the president that this is happening (which he will know with a very high degree of certainty), such a shutdown would be effected - and similar for pretty much every other civilized country on the planet.

Any deaths that would happen from shutting down the power grid would happen anyway, but this would allow for mitigation strategies to be put into place. Hospitals already have emergency generators, so it not like they're strangers to the concept. Also, the 2003 northeastern blackout affected 55 million persons for up to two days and only ten fatalities were attributed to the outage.

Anyway, this seems like a good thing to have a contingency plan written up for. The NASA article suggest there isn't, but that just might be that they don't know about it - they wouldn't be responsible for executing it anyway.
a friendly ISP always has rack space.. When you own a few data centers for yourself space is easy to come by.
So, I do a little bit of related research in this area:

This is typically called a "filament", a "plasma channel", and sometimes described as a waveguide. It requires high powers (~10^13 W/cm^2, usually femtoseconds in duration) depending on gas. It essentially works because the index of refraction has two nonlinear terms:

n(ω) = n_0 + n_2 I - n_plasma

the n_2 I makes it so that higher intensities (which occur closer to the center of the filament for a typical gaussian laser beam), have a higher index of refraction, causing the field to focus, increasing the electric field intensity at the center. However, when the field gets high enough, it ionizes the material, causing a plasma to form, which has a negative contribution, defocusing the filament. These two contributions balance out and cause a "waveguide" where the light essentially travels along a narrow channel, allowing the focusing pulse to travel longer without as much spatial dispersion.

You can't send another light beam along these channels, because after the beam has left, all that is there is a plasma channel, which defocuses and absorbs light instead.

This has been around for a while.

What is NEW here is that they modified their beam profile to have 4 or 8 or even an annular ring of these plasma channels. Accoustic waves propagate toward the center of this filament arrangement causing a change in the density (which changes the index of refraction, the index of refraction increases linearly with density) that makes the channels act like a waveguide for another light source. This source of the density change has a duration of microseconds. When the acoustic waves have dispersed, a thermal gradient has a similar effect, and this has a duration of milliseconds.

They used this method to channel light from a spark source while mostly maintaining the spectra of the spark.

Now, what this allows, or doesn't allow:

LIDAR is a possible use, but whatever you point this source at is going to have to be able to take 10^13 W/cm^2... and not a lot of materials can take that without breaking down. While there is good focusing and guiding of the light, I think single photons are probably going to have a high probability of being absorbed (the mode of the photon will overlap into the plasma channels, which will likely absorb it), The nice thing is that signals could likely travel through one of these channels (though there likely will have to be some dispersion compensation at the receiving end).
Thanks for the kind words!

Our target market, at this point, is: small businesses and end consumers.

Our goal is to eventually serve enterprise customers, but we're not going after that for the moment for several reasons (resources, depth of product offering, etc.)

A typical customer would be a small business that goes through 50 or so hard drives per year, enough that they'd want to send us a batch every month. They would also be interested of getting a third party (us) certificate of destruction for their records (industry standard).

Thanks for your feedback and questions. Let me know if there's anything else that I can answer for you. Cheers!

Can you explain the frequency dependence of the Faraday cage? The only time I can think of them being ineffective is against waves which are above the plasma frequency of the metal the cage is made of.
Look forward to seeing your ZenPayroll integration!
I suspect the confusion is due to the term "efficient", which has two meanings:
1. (technical) creating minimum waste
2. (common) effective.

In the real world, firms are undeniably effective compared to most/all real organization schemes. This article is simply saying that there are things that firms do which generate waste (meaning they are not "efficient"). This is a little silly in a way. Unicorns are also better than dogs (and all other real pets).
They also lack the base load characteristics of nuke plants.
From my understanding, these boxes are basically local copies of the entire Netflix online catalog - a catalog that frequently changes. How do these ~15,000 machines pick up new content? I assume they synchronize with the Netflix mothership every once in a while.

My question (without any intent to trivialize what Netflix is doing) is, isn't that just a good-old caching system?

But it makes me wonder if it would be possible to create a distributed, localized caching system? For example, if I watch The Avengers, my machine could be configured to cache a part (or all) of the movie. The more people watch it, the more it is distributed. Since Netflix can correlate location data with what movies are watched, they can target certain areas to cache certain movies more aggressively. When the next person in my neighborhood watches The Avengers, they would pull part of the movie from me (maybe the beginning until the rest buffers) and cache another part of it themselves for the next person in line. That way all the people in my neighborhood or adjacent neighborhoods don't have to pull the entire movie across the internet every time - instead, we help each other watch movies with higher quality.

On second thought, this may not be cheap considering the amount of development that may be required (and, at the end of the day, someone has to pay for this storage - although Netflix could, for example, offer personal mini-caching boxes in exchange for a monthly discount), but it's fun to dream about a sanctioned, decentralized, peer-to-peer movie service.

The SMB3 mini-game was based on the original Mario Bros; The author describes Punch Ball as a distinct game:

> This is almost identical to the original Mario Bros, except you can't knock enemies upside down by hitting the platform they're standing on. The only way to defeat them is by hitting the POW block or throwing the Punch Ball which Mario and Luigi carry around.
I'd at least nod to this argument a little had Saddam not been a secular dictator and an enemy of Islamist factions. He was an awful guy, but not one of them.

That's just a remake of the classic Mario Bros.; there's no punch ball in SMB3.
Either they knew it was a bluff or our intelligence was either totally wrong or allowed itself to be misled. None of those make the Bush administration look good.

I find the naïveté argument hard to swallow. The U.S. has the best intelligence agencies and network in the world.
I can understand the desire to make sure your money goes towards actual programs instead of overhead, but MSF - at least in the US - is one of the better big name charities I can think of on that front.

86% for program costs. Wellbody is at 95%, but they don't have any salaries or employee benefits listed, among other things that inevitably gobble up some small percentage of money for bigger charities.
Yes, they are common, they are called surge arresters.
Indeed. And once you have interfaces with default implementations, adding state gets you even more power. For example, intrusive reference counting and intrusive data structures generally are very useful applications of multiple inheritance.
Was it based on the original Mario Bros? I'm talking about the mini game you can play when Luigi and Mario occupy the same space.

You can knock enemies out by hitting the platform they're on OR by hitting the POW block and there's no ball, but other than that, the enemies and level layout seem to be identical.

Since the level layout is identical (and I don't remember a POW block in the original SMB), it seems more like the mini-game is based on Punch Ball rather than the original Mario Bros.
The problem with analyzing programs in the context of a fixed memory limit is that you would have to revisit all of the proofs whenever the fixed limit was increased. If you can prove something true for unlimited memory, it's also true for any limited amount of memory.

>>we often find it convenient to analyze it as Turing complete anyway

It's convenient, because the proofs will still be true even if memory sizes grow by 500x. Turing machines clearly don't have a real, material existence, similarly to real numbers (assuming that all actual numbers are finite). Real numbers can be considered as modeling integers that are arbitrarily large.
I blame conservatives for this too. They laughed for 50 years at all the hippies and eggheads who talked about the need for alternative energy. One of Reagan's first acts was to take the solar panels off the White House.

Sounds like there's a bit of "no one ever got fired/pilloried for claiming that things were going to be worse than they turned out to be!" going on. I remember a lot of that going around in 1995-99.

I imagine that would be an extreme upper bound. But yes, it would cause damage, economically and possibly damage communications. We'd recover and I don't think it will take 10 years. We're continually reducing the costs of launches which is a huge factor in the monetary damages (potentially relaunch all communication satellites).

We'd be out billions of dollars in spy satellites too so maybe we'd triage on what we decide is important to launch after such an event.

New models are expected to come out soon, so if possible I would wait for a bit: http://buyersguide.macrumors.com/#Mac

I was in a similar situation last year (coming form an old MBA) and I decided to go with the Pro. The weight difference is not huge but noticeable. In terms of performance you don't need to worry about the Air, it'll be able to handle everything just fine. What really sold me on the Pro was the retina display. Beautiful. Once used to it it's really hard to go back to non-retina. What the Macbook Air has going for it is slightly longer battery life. So, I'd look at it as tradeoff between retina display and battery life. Don't even worry about performance.

>Maybe you should try looking at pages 37-42 which defines 13 different categories of suspected terrorists. I fail to see why you don't think this is relevant.

Because you don't have to be a Suspected Terrorist to be put in the TSDB. Which means that there are a whole host of things that aren't on those lists that can land you in the TSDB.

>You're conflating two completely separate branches of government.

No, I'm really not. "court" is not unique to the judicial branch, for example, courts-marshal are conducted within the military and not under the judicial branch.

>That's because this is administrative guidance.

Yes, which means that there should be better policies in place to keep this out of the judicial courts.

There are a lot of modern facilities providing solar flare predictions, many are old and many are new. Some are space based and a lot are ground based (radio telescopes and coronagraphs) Government agencies amalgamate data from all the sources to come up with the best predictions. We always have more than 12 hours to prepare after spotting something from surface on the Sun, the accuracy of predictions improves as time goes by, the 20 minute mark is generally the time it takes for a fast CME to go from L1 Lagrange point to Earth. L1 is where multiple aging solar observatories collect insitu data, but we usually know before then if a strong event is Earth directed.

Version numbers and alpha/beta/delta labels vary and are subjective in practice. I've seen plenty of examples and counter-examples of version numbers and beta labels to not put much merit toward such labels.

Yes, it is unfinished. I'd rather have Apple do what it's doing -- i.e., releasing Swift as a beta and changing things with feedback -- than do the opposite, which would be keeping it closed until it was super polished as they felt it internally.

I hate seeing this "damned if you do, damned if you don't" scenario all the time.

(1) Pre-release for feedback, get complained at for it not being finished.

(2) Polish and release later on, get complained at for not opening it up earlier for public feedback and testing.

Apple has clearly stated that it's pre-release, that it's not set in stone yet, and that they're open to feedback (which they have been).
I wish. On OSX, I often see a connection with full bars, which fails to connect. I have no idea why. It's incredibly frustrating.

I've gotten by for quite a few years with my old GP2X-Wiz. Fantastic battery life, and big library of software for it, including lots of very good emulators. I've even watched quite a few movies on it and played some SCUMMVM games on the touch screen. It's about the size of a GBA and has been a near constant companion to me.

It'll do just about anything up to SNES, which includes Neo Geo, and a huge subset of the MAME library.

just checked ebay since the company that made the GP2X-Wiz is out of business, holy smokes I can't believe how much they're going for

These days, I'd probably go in for a GCW-Zero, an A380e, or if you have the money, get an NVIDIA Shield (on my list to replace my GP2X-Wiz).
I started with QBasic also. Things like that still exist. See http://plnkr.co/ and others.

In II-1-5 [1] we learn that magnetism is a relativistic effect whose strength is v^2/c^2. This ratio is a very small number for the electron drift velocities associated with typical currents in copper wires, yet we perceive magnetic forces because positive and negative electric charges in the wire are balanced to better than v^2/c^2.

Can anyone indicate how + and - charges are distributed in a CME? Are there strong electric fields due to local charge imbalances? For the magnetic field, it's tempting to say that the drift velocity of charges in a CME is high (as much as 0.001c) but then wouldn't charges of both polarities be moving with that (average) speed? Perhaps there is some initial motion when the charges are ejected from the sun?
