I've done reasonably well simply investing in SPY and holding it long term. Badly managed companies get dropped from SPY because their cap evaporates, and well managed companies get on it and stay on it.

SPY is extremely relevant to the average investor, and even more so to the below average investor.
If I recall correctly, the Lerner’s email loss was explained by the crash of her computer. Thus, we are having a strange series of 7 computer crashes for employees involved in the scandal: "He ran in to my knife! He ran into my knife ten times!"
The Predator does not have a radar which would allow it to launch the AMRAAM at long range. The AIM-120 has a radar for terminal guidance, but it relies on the aircraft to pass target information for early flight.
Are the videos necessary, how about photos and a timer for low bandwidth/speed? Just a though. ;)
His claim is that stealth only works against radars in a particular frequency band, and that long-wave radars designed to defeat it can do so easily. Saddam Hussein didn't have those; the point is that the F-35's adversaries (anyone with an air defense system designed after the F-117 went public) likely do.
Aren't the missiles they fire subject to the same jamming problems?
Lots of lessons for software engineers in this lovely interview. Like Knuth, Pierre Sprey seems to relish "beauty in the particular".

"The goal of generalization had become so fashionable that a generation of mathematicians had become unable to relish beauty in the particular, to enjoy the challenge of solving
quantitative problems, or to appreciate the value of technique" - From the preface to Concrete Mathematics; Graham, Knuth and Patashnik
It doesn't work that way. Some nominal "designer" might doing engineering drawings, but with so much input from other engineers that what you might think of as "design" just doesn't exist.

Oh, sure, Old Man Douglas might have drawn the outline of the DC-7's tail up in the old "lofting room", or someone said "one engine" for the F-16, or "elliptical domes" for the Titan fuel and oxidizer tanks, but after that, saying someone is THE designer of a large project is just a fib.
>Correction: him and the fighter mafia hated the F-15. His work lead to F-16 and F/A-18.

If I recall correctly the F-15 was partly his baby but he only got in mid-way so couldn't make it as good as he wanted it. Then the Lightweight Fighter program was run by him and generated the YF-16 and YF-17 prototypes. The YF-16 won the competition and became the F-16. Then the Navy didn't like a single engine plane (or didn't like an air force plane) and took the YF-17 and made the F-18.

So I doubt they hated the F-15 but they definitely liked the F-16 better. I'm not sure how happy they were about the F-18 given that it was a run-around their LWF process.
Or, you know, people who aren't "a certain segment of US middle class". If you come from a different culture (NOT "weird" as a8da6b0c91d so rudely puts it), it can be a pretty difficult prospect facing burgers and "bread and milk" to survive on.

Please apologize my misunderstandment.
Alpha radiation from outer space can't penetrate the atmosphere, for much the same reason you can't fire bullets 1km underwater from the surface. The only source of alphas from cosmic radiation would be from some sort of indirect effects such as direct fissioning (at ground level) of a nuclide by cosmic radiation into an alpha + daughter.
I'm more than a little skeptical of this. While it is all correct in principle--a webcam CCD target can certainly detect alphas, and electrostatic fields can sweep charged particles into a detector--the details are problematic, and there's no actual demonstration of the sensitivity of the device.

A typical camera target is about 3 mm on a side, for a total sensitive area of ~1e-5 m2. The muon flux at sea level is about 1 per cm2 per second, or 36 million per m2 per hour, or 360 hits per hour on a camera target, so even granted that the "active" area of the target is only a few percent of the physical area, muons more than account for the signal he is seeing, and muons deposit a lot of energy.

The electostatic concentrator is an interesting feature. Charged nuclei typically attach themselves to dust motes in the air, which are then swept along by the E-field. It isn't clear why he needs such high voltages to get 50 V/m over a few centimetres, and in my experience Cockroft-Walton generators are easy to build but hard to make work. With such tiny capacitors any stray leakage current would destroy the effect, and he does not anywhere measure the voltage produced.

The enhancement of the count rate could be accounted for by electrical noise from the CW driver circuit.

This is pure speculation on my part, based on a good deal of experience designing and building radiation detectors, but I'd like to see a lot more evidence before I said this was an effective radon detector.

An alternative, easier to debug and demonstrate, and more likely to work approach would be to use a commercially available activated zinc sulphide sheet with the camera target as the detector: http://www.eljentechnology.com/index.php/products/zinc-sulfi...

FTTN is both fine on its own right, and a good incremental step toward FTTP. Its the basis for BT's broadband strategy in the U.K., which everyone holds up as great model.

As for this not being a problem flyover country, you're right. But flyover country also doesn't have the density for good bang for buck infrastructure development. The reason why places like Poland and Romania stand out is they combine the density of major American cities with the desparation to stand out. Warsaw wants to be the next San Francisco. San Francisco doesn't.

Aral Balkan gave a talk on a CRDT called WOOT for text editing[1] that I found really helpful to get the general idea of the concept. (Really only the last 8 or 9 minutes of his talk.)

If you want more of the nitty-gritty on some of the different types of CRDT, there's fairly readable paper on the topic[2].

From there, you can start using Google Scholar to find the other papers that have been written.

Anime isn't very cross-compatible in terms of both the things its fans care about and community overlap with fans of regular movies/TV. Though I don't really have a good means to support my assertion other than that most Anime torrent or information sites are separate from normal TV/Movie sites, and the reverse holds true as well - IE normal TV/Movie sites rarely have good information on anime. So there's definitely a schism.
> the company doesn't receive any benefit from your purchase except at IPO

This is incorrect:

1. corporations often issue more stock and sell it in order to raise working capital

2. employee compensation often comes in the form of stock in one way or another

3. a rising stock price means a company needn't pay out dividends in order to satisfy investors

4. without a rising stock, a company will find it much, much harder to attract investors, employees, borrow money, attract customers, etc. Few want to get on board with a loser company.

How many cheap, disposable, locally-networked drone-bombs could you make for the price of an F-35? How many could you make by spending 1% of the $1Tr tag the F-35 program has cost?

Manned planes are the cavalry of the 21st century. They're glamorous and dashing, but also insanely high maintenance.

On-board AI will only get better. And you only need one kill from a disposable unit to take out a manually-flown enemy.
I don't understand why drones must inherently have limited ammunition or bomb payloads. Just make the same big beefy airplane you were going to, but instead of having a human fly it by wire, have a computer fly it by wire. Outfit it with more sensors if necessary, but I suspect modern fighter jets are pretty well decked out in that department already.

The only thing I can think of is creative solutions to incoming missiles, but if that really is something that computers cannot currently do, I doubt that will remain the case for long.
It's nice to see lots of some experiments come out of Facebook, but they should really be seen and treated as such.

Any tips on cool parts of the RTP area? I was at a conference in downtown Raleigh for a week two years ago, and was kind of surprised that the downtown is super-small. Had two nice coffee shops, but didn't feel like the downtown of a 500,000 person city; almost the kind of 5-block downtown you'd expect for a town 1/10 of that size. I might go again this year, and am hoping to find somewhere to stay where there's more stuff going on, but am not quite sure where that is.

If you don't care about latency, and in this "DSP sandbox" application you probably don't, JavaScript is fine for real-time DSP. JS under V8 and similar engines can be quite fast.

You aren't going to digitize 100 MHz of RF spectrum and build an SDR in JavaScript, but for audio rendering work it'd be fine. Cool hack.
Last time I was in Tokyo the subway stopped running very early (either midnight or 1 AM) compared to NYC where it never stops.

That has obvious benefits such as helping maintain cleanliness, but I still wouldn't eat a meal without washing my hands after riding on the Tokyo subway.
this is what I was reffering too, the compilation step. It seems very daft for me to loose the closure compiler. I assume lein keeps the jvm hot, if not writing a script to do it should be pretty simple.
You've just fallen prey to a logical fallacy.

Just because SOME radars cannot detect stealth aircraft it does not immediately follow that NO radars can detect stealth aircraft.

That's not entirely true. The salary cap is because if teams paid the fair market value, the teams with a larger budget would be able to run away with it like the Yankees did in baseball (with over twice as many World Series titles as the next best). It keeps the league artificially competitive.

Keeping the business world artificially competitive is an interesting idea, and not as bad as I initially thought.
Paying 1 new person 100k costs more than paying 1 person 100k extra.
It's pretty widely known that stealth doesn't make radar useless. The focus is to reduce the accuracy of radar and the response time of opposition.

Just a guess: the A-10 is designed as a support aircraft for ground troops, which means that if it does its job perfectly, the Army gets to claim a decisive victory. The F-15 is an air-superiority fighter, which means that if it does its job perfectly, the Air Force claims a decisive victory. Inter-service rivalry is a Thing...from the POV of an ordinary citizen, it doesn't matter as long as we whup the bad guys, but from the POV of a career military bureaucrat it matters a lot whether the victory is credited to his branch of the service.
can you tell more about how you coded the fundraiser modal? is it just checking the balances on those addresses then converting them to USD? im sure its a simple solution but i'd be happy to hear more about it - i was thinking of making a similar one for my own project, but it would be good if it displayed different addresses per visitor for better obfuscation...lets say have half of a wallet full of addresses, then also check server side whether the displayed is a valid one

I think the fact that normal TV/Movie sites lack information on Anime led to the schism more than anything. The same things the Anime community has developed could be equally applicable to normal TV, especially in the age of DVRs and streaming: Anime fans were watching things asynchronously long before anyone else
The Luftwaffe had an obsession with dive bombing after the initial success of the Stuka. However, making every aircraft design capable of dive bombing wasn't a good idea (fortunately):

I think you're overstating what the AIM-120 can do, based on what I've read, it's radar seeker head is only so effective.

First it has to be directed in the right direction. Need a good radar system somewhere for that. It also has a much higher hit probability against a target, especially a distant one, if you can send it remote course corrections. Note that neither of these need to be on the launching platform, but they need to be somewhere in the local area.
Pierre Sprey is way off base on practically everything.

Almost no air-to-air combat starts out within visual range and this has been the case since the 1980s when the F-16 became available.

Part of the reason the F-16 became popular is that its cheaper to buy and operate compared to the F-4 and F-15, and even the F-16 Block 5 had an avionics package that made it quite capable in combat and achieved its first Air-to-Air kill in 1980. Smaller jets like the F-5E and the SAAB Gripen don't have nearly the same combat radius on internal fuel.

The F-35 is one of the most agile jets available when loaded for combat. Most of the claims about the F-16 are in airshow configuration and not combat loaded with drop tanks.
When I get a cold email, especially if the email doesn't show any particular knowledge about who I am or what I do, I almost always want to know how the person emailing me came across my email and decided to email me. It's fine if I get an email about an opportunity isn't a fit for me, but I would like to know who or what gave the impression that it was so I can correct it.

The forward request is a little grating, but I used to reply to recruiters asking how they came across me, regardless of whether they included that line. Virtually none of them replied back. Lately, I've just been junking any recruiter email without replying back if it's clear they don't know anything, or they know the bare minimum, about me.

If a recruiter emailed me, opened the email up with an explanation of how they came across me and why they thought I'd be interested, I'd be much more inclined to respond with more information about what I'm looking for even if the offer in their initial email is not even close or if they asked me to forward the email to someone else.
Wars raise many ethical issues. I'm surprised there isn't a debate going on about the use of manned vehicles in wars.

Why should drones? Even consumer drones that you can pick up today on amazon know how to return to base when they lose communication. Those depend on GPS, but I see no reason why they could not anticipate GPS jamming and incorporate dead reckoning.

Australia is replacing its retired F-111 fleet with the F-35 so we may end up sole user in end...again. The F-111 at least had use in a long-range anti-shipping role once it was upgraded for the Harpoon.
Being honest and forthright goes a lot further than you think. Startups have risk, outline the risk, and ask for what you want.

You don't need the thousands of investors who want you to work for free, you need one who believes in the business enough to think the CEO is worth being paid. If the CEO isn't worth being paid the startup isn't worth investing in.
As other discussions have pointed out, that's not all that useful if you can't then kill them, which existent long wave radars are rather bad at.
no most missiles have internal guidance systems. Inertial guidance, preset guidance etc.
$2.50? Now I know I'm old. Last time I rode the NYC bus/subway regularly, the price hike to 75 cents was controversial news.

Still I agree that it's a good deal considering how far you can travel.
As a category, anime has some unique characteristics you don't (generally) find in other TV or film categories:

1) Strong user/viewer affinity for the category. Generally speaking, you don't find that your typical Grey's Anatomy viewer is a "medical drama fan," who seeks out other medical dramas at every opportunity. Likewise, a rabid Family Guy viewer is probably not an "animated comedy fan," barring a very tiny and borderline-insignificant segment who is. They might be fair-weather fans, but their consumption of those categories is ad-hoc and show-dependent. Anime fans may come to the category seeking a particular show -- Cowboy Bebop, Attack on Titan, or what have you -- but many of them stick around for anime as a category. Someone who likes Law & Order isn't going to seek out other legal procedurals, but someone who likes a mecha show is going to look for more mecha shows.

2) Anime is underrepresented on TV/movie services like Netflix, or in other "mainstream" TV/movie sites and aggregators. (That said, there are anime-specialist players in these markets, such as Crunchyroll and Anime Network.)

3) High fan engagement online, more so than with many other categories of film or TV. Thus, a more addressable user base.

Of course, these factors can also work against you. As another commenter has pointed out, the characteristics that make anime unlike other genres also makes bridging the gap between anime and other genres very challenging. Anime companies are usually in the business of addressing the TAM in the anime category; they seldom find success using anime as a beachhead to attack TV or movies in general. Not saying it can't happen, or that it's never happened. But it's difficult.

The argument goes, if you want to win the next air war, you should use drones. lots of drones. Air to air combat is all missiles, and each of those missiles is half a million dollars.

Now, I'm not aware of an autonomous drone that can shoot down an f-22 with a missile, but it seems like a solvable technical challenge, especially if you're willing to throw a trillion dollars at the problem.

So anyway, for each f-22 send up 7 drones. one for each missile, and one to survive to get the kill, as long as the 6 lost drones are cheaper than the f22, you're winning, kinda.

Furthermore, pilots are expensive and take time to replace. I doubt there are even 10,000 combat pilots in the world (wag) kill off a few thousand, and the drones are against rookies. All the while, the drone software is improving and getting even tougher to kill. And, the drones should be capable of things that that human pilots just can't accomplish - high g turns for example.

Self driving cars aren't better than the best drivers, but they're way above average drivers, eventually the robots will be better. Same with jets. why not start now?
> On-board AI will only get better.

The fact that this terrifies so few people terrifies me.
Depends on the mechanism used by the missile to follow the target. My impression is that most missiles don't have guidance systems that require direct communication after launch,
