Submission + - How the U.S. Army Plans to Defeat the Unthinkable: Drone Swarms (nationalinterest.org)

An anonymous reader writes: Yes, the US military loves to use drones against enemies who have no defense against them: think terrorist cells, ISIS/IS/ISIL, the Taliban etc. However, drones are getting cheaper to make, easier to use, and more technological sophisticated. The day is coming--and coming quite soon--where U.S. military planners will have to defend against drones. And they may have to fight off lots of them.

The U.S. Army seems to have some ideas: "The Army wants a weapon that can both detect and destroy a swarm of UAVs. It would "disrupt these platforms’ autonomous flight-control and navigation capabilities or cueing a weapons system like the Remotely-Operated Weapon Station (RWS) or other medium or large-caliber weapon.," said the Army's research proposal. The system would be mounted on vehicles or at Army installations. More interesting, the Army proposal also notes that it might be mounted on UAVs, which raises the possibility of using drones to shoot down other drones."

Couldn't the same argument be made that a person of the Earth made enough money to visit the ISS, what's your excuse for not having that much money?

An old saying (by Confucius, I think) goes like this: "It is a shame to be rich in a poorly-governed country. It is also a shame to be poor in a well-governed one."

In most cases, public utilities have a much lower cost structure than private enterprise.

Citations?

But what they don't want is to have lower cost providers step in and pick off the marginal territories while they are holding them back.

Do you have any proof to this conspiracy theory?

Nobody (in private business) likes to maintain infrastructure, keep the snow plowed and potholes fixed. But that's what municipalities are good for.

Actually, no, they are pretty bad it — and the bigger the city, the worse they are.

This is why Comcast and TWC wan to merge.

The would-be merger has no relevance to the situation — thanks to the previous governmental idiocy of allowing monopolies in cable TV, the two companies do not serve the same markets anywhere in the nation.

In some states, building municipal broadband is prohibited altogether.

And a good thing that is. If it were a good idea — something enough people want bad enough to be willing to pay for it — it would not have required tax monies.

I wish, the same principle (hi, Mr. Okkam), were applied more often.

Whatever you think of their politics

Well, it is exactly those policies, that made them a pariah of the world (except, of course, Russia) and caused the very poverty, that forced them cancel the space-program.

Spaceflight is one of the few remaining areas of "friendly rivalry" where everybody still cheers for the other teams' success

That may be so between Europe and US. Russia — and knowing Russian I know it for sure — stopped cheering American successes about 10 years ago. USSR never did either — when the Moon-landing was watched world-wide by everyone with a TV, USSR's television was broadcasting a ballet — the news appeared in news-papers the next day, but there certainly was no "cheering" of the other team's success.

I dare speculate, the official Iran today are much the same. As the old Russian saying goes: "tell me, who your friend is, and I'll say, who you are."

I take it you don't remember what it was like when those were all held by single entities.

I do remember it, and I mentioned that unfortunate state as one, brought about by an earlier attempt by our government to regulate cable companies. In exchange for the regulation they wrestled monopoly powers — and ran with it (like AT&T did decades before that).

That mistake was corrected in the 90ies, though the problems caused by earlier government stupidity remain. To now point at them and argue, we need more governmental control (as duckintheface is doing above), requires a very special kind of stupid.

the mantra of "free markets"

Yes, leave it to Illiberals to criticize free markets. Government take-over did so well for railroads, public transport, and telephone-service, what could possibly be wrong about adding Internet to the mix?

This has resulted in a protected monopoly for these ISPs. [...] treat the ISPs as utilities so that their rates will be controlled

Yes, an earlier mistake of our government letting corporations have monopolies (of cable TV) still needs to be dealt with. But the price-control you are advocating in the next paragraph only makes things worse. Because the incumbents are much better versed in dealing with the government regulators, than a newcomer will ever be.

And, while you are accusing Republicans of baby-eating, it is the Democrats who are owned by the Big Cable.

This is really a free market in content

So, free market in content is a good mantra, but free market in service provision is bad? Or did you change your mind by the end of typing your post?

Submission + - Why Some Teams Are Smarter Than Others

HughPickens.com writes: Everyone who is part of an organization — a company, a nonprofit, a condo board — has experienced the pathologies that can occur when human beings try to work together in groups. Now the NYT reports on recent research on why some groups, like some people, are reliably smarter than others. In one study, researchers grouped 697 volunteer participants into teams of two to five members. Each team worked together to complete a series of short tasks, which were selected to represent the varied kinds of problems that groups are called upon to solve in the real world. One task involved logical analysis, another brainstorming; others emphasized coordination, planning and moral reasoning. Teams with higher average I.Q.s didn’t score much higher on collective intelligence tasks than did teams with lower average I.Q.s. Nor did teams with more extroverted people, or teams whose members reported feeling more motivated to contribute to their group’s success. Instead, the smartest teams were distinguished by three characteristics (PDF). First, their members contributed more equally to the team’s discussions, rather than letting one or two people dominate the group. Second, their members scored higher on a test called Reading the Mind in the Eyes, which measures how well people can read complex emotional states from images of faces with only the eyes visible. Finally, teams with more women outperformed teams with more men. It appeared that it was not “diversity” (having equal numbers of men and women) that mattered for a team’s intelligence, but simply having more women. This last effect, however, was partly explained by the fact that women, on average, were better at “mindreading” than men.

Interestingly enough, a second study has now replicated the these findings for teams that worked together online communicating purely by typing messages into a browser . "Emotion-reading mattered just as much for the online teams whose members could not see one another as for the teams that worked face to face. What makes teams smart must be not just the ability to read facial expressions, but a more general ability, known as “Theory of Mind,” to consider and keep track of what other people feel, know and believe."

Submission + - Book Review: "FreeBSD Mastery: Storage Essentials", by Michael W. Lucas (amazon.com) 1

Saint Aardvark writes: (Disclaimer: I received a free copy of this book for review. Disclaimer to the disclaimer: I would gladly have paid for it anyway.)

If, like me, you administer FreeBSD systems, you know that (like Linux) there is an embarrassment of riches when it comes to filesystems. GEOM, UFS, soft updates, encryption, disklabels — there is a *lot* going on here. And if, like me, you're coming from the Linux world your experience won't be directly applicable, and you'll be scaling Mount Learning Curve. Even if you *are* familiar with the BSDs, there is a lot to take in. Where do you start?

You start here, with Michael W. Lucas' latest book, "FreeBSD Mastery: Storage Essentials". You've heard his name before; he's written "Sudo Mastery" (which I reviewed previously), along with books on PGP/GnuPGP, Cisco Routers and OpenBSD. This book clocks in at 204 pages of goodness, and it's an excellent introduction to managing storage on FreeBSD. From filesystem choice to partition layout to disk encryption, with sidelong glances at ZFS along the way, he does his usual excellent job of laying out the details you need to know without every veering into dry or boring.

Do you need to know about GEOM? It's in here: Lucas takes your from "What *is* GEOM, anyway?" (answer: FreeBSD's system of layers for filesytem management) through "How do I set up RAID 10?" through "Here's how to configure things to solve that weird edge-case." Still trying to figure out GUID partitions? I sure as hell was...and then I read Chapter Two. Do you remember disklabels fondly, and wonder whatever happened to them? They're still around, but mainly on embedded systems that still use MBR partitions — so grab this book if you need to deal with them.

The discussion of SMART disk monitoring is one of the best introductions to this subject I've ever read, and should serve *any* sysadmin well, no matter what OS they're dealing with; I plan on keeping it around for reference until we no longer use hard drives. RAID is covered, of course, but so are more complex setups — as well as UFS recovery and repair for when you run into trouble.

Disk encryption gets three chapters (!) full of details on the two methods in FreeBSD, GBDE and GELI. But just as important, Lucas outlines why disk encryption might *not* be the right choice: recovering data can be difficult or impossible, it might get you unwanted attention from adversaries, and it will *not* protect you against, say, an adversary who can put a keylogger on your laptop. If it still make sense to encrypt your hard drive, you'll have the knowledge you need to do the job right.

I said that this covers *almost* everything you need to know, and the big omission here is ZFS. It shows up, but only occasionally and mostly in contrast to other filesystem choices. For example, there's an excellent discussion of why you might want to use FreeBSD's plain UFS filesystem instead of all-singing, all-dancing ZFS. (Answer: modest CPU or RAM, or a need to do things in ways that don't fit in with ZFS, make UFS an excellent choice.) I would have loved to see ZFS covered here — but honestly, that would be a book of its own, and I look forward to seeing one from Lucas someday; when that day comes, it will be a great companion to this book, and I'll have Christmas gifts for all my fellow sysadmins.

One big part of the appeal of this book (and Lucas' writing in general) is that he is clear about the tradeoffs that come with picking one solution over another. He shows you where the sharp edges are, and leaves you well-placed to make the final decision yourself. Whether it's GBDE versus GELI for disk encryption, or what might bite you when enabling soft updates journaling, he makes sure you know what you're getting into. He makes recommendations, but always tells you their limits.

There's also Lucas' usual mastery of writing; well-written explanations with liberal dollops of geek humour that don't distract from the knowledge he's dropping. He's clear, he's thorough, and he's interesting — and that's an amazing thing to say about a book on filesystems.

Finally, technical review was done by Poul Henning-Kamp; he's a FreeBSD developer who wrote huge parts of the GEOM and GBDE systems mentioned above. That gives me a lot of warm fuzzies about the accuracy of this book.

If you're a FreeBSD (or Linux, or Unix) sysadmin, then you need this book; it has a *lot* of hard-won knowledge, and will save your butt more than you'll be comfortable admitting. If you've read anything else by Lucas, you also know we need him writing more books. Do the right thing and buy this now.

Nope. These guys may be Christian and they may be terrorists/criminals/nasty, but they aren't Christian terrorists — that is, they are fighting their fights — and committing their outrages — for a variety of reasons, but not because a scripture tells them to.

on top of the clichéd plethora of abortion bombers...

Same thing — you can be a good Christian and not bomb abortion clinics. In fact, you can even disapprove of such bombings done by others. But you can not be a good Muslim and tolerate mocking of the Prophet.

That's the fundamental difference, which you refuse to acknowledge despite overwhelming evidence. Thanks for playing.

Submission + - Sorry Kinect: Apple Wins Gesture-Control Patent (pcmag.com)

mpicpp writes: The U.S Patent and Trademark Office (PTO) today awarded Apple an incredibly broad patent for gesture-based controls.
The patent covers a "three dimensional user interface session control." In other words, you wave your hands and something happens on your device. When Apple bought PrimeSense last year, it was pretty clear the company wanted to own some—if not all—of the gesture-control space. Since then, all of PrimeSense's patents have been reassigned to Apple.

At its most ambitious, gesture controls deliver a Minority Report-style interface you can navigate by pinching your fingers in the air. At its worst, you are left waving your arms at an inanimate object like Harry Potter with a broken wand. Unfortunately, the reality is that gesture interfaces have been more like the latter.
The best known, and most controversial, gesture control system is the Kinect. In fact, PrimeSense developed the Kinect for Microsoft, which made it a central part of its Xbox 360 and Xbox One consoles. The technology is pretty amazing, especially in its latest, high-definition incarnation. The Xbox One Kinect can detect up to 25 joints across six people. It can read a player's heartbeat, and with 1,400 points of articulation, it can tell if your mouth is open or closed. It is undeniably kick-ass technology, and no one cared.
