  1. It's blue lines silly! on What Wi-Fi Would Look Like If We Could See It · · Score: 1

    Some odd time ago I was in a training class for a job supporting smart phones and similar devices (oh god I have fallen so far from grace!). The instructor scribbled a quick visualization of signals from a cell tower and wifi. She drew crude waves emanating from a tower and wifi device (she drew them in blue)--of course we all got it, right? There was one student in the class who stopped everything to mention that he lived very close to a tower and never saw these blue waves emanating from it or his wifi router, and wanted to know why. With the exception of those chuckling, the class was otherwise stunned into silence. The individual was asked to not return the next day.

  2. Re:the units talk to each other.. on Self-Assembling Multi-Copter Demonstrates Networked Flight Control · · Score: 3, Interesting
    No. Each component represents and individual sensor array and its own individual main computer. They work and communicate as a team. From the freakin article:

    The individual vehicles of the Distributed Flight Array have fixed propellers that can lift them into the air, but the resulting flight is erratic and uncontrolled. Joined together, however, these relatively simple modules evolve into a sophisticated multi-propeller system capable of coordinated flight. The task of keeping the array in level flight is distributed across the network of vehicles. Vehicles exchange information and combine this information with their own sensor measurements to determine how much thrust is needed for the array to take-off and maintain level flight. If the array’s leveled flight is disturbed, each vehicle individually determines the amount of thrust required to correct for the disturbance based on its position in the array and the array’s motion.

    Consider reading my above comment Technology marches on. It leads with a suggestion specifically addressing those who don't RTFA - take a look and follow the advice.

  3. Technology marches on on Self-Assembling Multi-Copter Demonstrates Networked Flight Control · · Score: 3, Insightful

    For those who don't RTFA, I suggest you at least look at the 'summary' youtube video towards the bottom of the article, it's only a couple minutes long and is pretty awesome.

    While this may not bare a commercial application in itself, it is still a big step forward in studying how robots can learn to react to each other as individuals while cooperating as a team. Again, while this implementation of the idea at hand may not directly have any obvious use other than research, it is that research and the basic premise behind it that will carry on into future applications we may not even understand yet. I know that there is a lot of research into autonomous cooperation between robots to achieve a goal, but this is stepping up the game.

    As the years go by I am constantly fascinated as innovations and advancements in technology accelerate increasing rapidly. We are almost there, however, it has already become beyond impossible to understand just what 'there' will turn out to be. I think we'll know sooner than later.

  4. Depends on platform on Poll Shows That 75% Prefer Printed Books To eBooks · · Score: 3, Interesting

    I prefer ebooks to printed books, but only on my kindle paperwhite. Reading on a backlit display for more than a short amount of time causes me a headache and interferes with my sleep if I read before bed. I would go so far as to say that the act of reading on a paperwhite is a superior experience to reading on real paper (as far as my own two eyes go). As for the question of wether or not my ebook library will still be there in fifty years, we'll have to see, but I suspect we will be downloading books into our head by then anyway.

  5. Assholes: Armed and Armored... to the teeth on Rise of the Warrior Cop: How America's Police Forces Became Militarized · · Score: 2

    I live in Kansas City and I've noticed--in somewhat disbelief--over the last few years, the number of everyday cops rising who wear increasingly comprehensive body armor for regular patrolling and traffic stops. The armor itself almost appears to be intimidating on purpose (it makes them look like bad asses). This is not yet universally the case here, but it gets worse every year. To make the situation even more fun, the more they militarize the bigger assholes they become. Unless they are simply out collecting for their quotas on speeding tickets, they can cause a lot of trouble and their intimidation techniques make me disappointed in my country. I have a story about recently being pulled over for a tail light, that highlights all, but I don't have time to hammer it out here, so just trust me it was bad, but after an hour they finally had to let me go because they didn't have shit on me. Funny part is, after the hour long ordeal of being severely harassed and having certain rights trampled on, they had completely forgotten about the tail light by the time it was all said and done. We really do live in a police state, and I'm not sure if we can do anything about it.

  6. Obligatory overlords comment? on ACLU Study Says Police Cameras Create Database of Our Movements · · Score: 2

    Nope, not this time. I cannot find any room for humor as I read this and put together the sum total of all we have learned so far--moreover mostly recently--about domestic surveillance. Where will it end? Can we stop it and reverse it, or are we fucked for sure? What may come to light next? As an American I am a patriot regarding the Constitution, the Bill of Rights, and the founding ideals of my nation. But, at the same time, the reality we are now facing is harsh, confusing, desperate, and scary. I don't know what to think about my country anymore; our government has declared that every citizen is a criminal suspect subject to all kinds of constant surveillance, it's like they're just waiting for a slip up that gets you busted--mind your thoughts, thinking the wrong thing, or worse saying the wrong thing, could one day soon be your undoing.

    It's not our fault, but maybe we could have done more to prevent this. And so it goes...

  7. I like it! on Apple Sued For Man's Porn Addiction · · Score: 4, Funny

    While I think he's completely crazy to blame his addiction on Apple, the 'Safe-Mode' is not an altogether bad idea. Wouldn't it be nice to know your kids new MacBook had sex simply turned off?

    It would take them days, perhaps even weeks to find a way to circumnavigate the measure. Just think how much our kids could learn about BSD! The really aspirational ones might even learn to cover their tracks with a terminal and Vim!

  11. A little off topic on Lincoln's Surveillance State · · Score: 1

    A little off topic, but pertinent all the same. The events as of late have had me wondering: if the majority of the American people are driven to revolt in similar fashion to the Arab spring type revolts (that our government overall praises), would our own military fire on us if ordered?

    A couple of years ago, I may have very well modded this question down.

  12. Re:This will work with....? on Mount Everest Gets 4G Connectivity · · Score: 1

    Thank you for clarifying that. It also occurs to me that in order to have wifi, you would also first need some sort of other broadband internet in place... so I guess that's that.

  13. This will work with....? on Mount Everest Gets 4G Connectivity · · Score: 1

    Considering that people visit and climb everest from all over the world with phones from all carriers (including phones without SIM cards), wouldn't adding extensive wifi not make more sense? At least I'm guessing that these 4g towers will only work with Huawei as individual 4g implementations tend to be carrier specific. It would be nice to know that I could bring my Sprint phone to Everest and be able to stream, blog, and Skype with it. I'm not saying you can't have 4g also, but if it's limited to a single carrier, it is, well... limited.

  14. Elon does it again on SpaceX Grasshopper Launch Filmed From Drone Helicopter · · Score: 5, Insightful

    Elon Musk, with his money, and business genius, in combination with overall nerdiness, is bent on dragging us kicking and screaming into the long overdue sci-fi future we have all been been impatiently waiting for and desperately dreaming of. The rapid progress his technology companies are achieving is nothing short of breathtaking. He pushes limits so far, and so hard, that those nearly impossible limits have been powerless to push back. I for one have no problem with this. I believe Elon Musk will take his place among the most important and well recognized figures in history. We should all feel very lucky to have him.

  15. Re:How does it "navigate"? on SpaceX Grasshopper Launch Filmed From Drone Helicopter · · Score: 2

    If you look very closely at the video in high-res at full screen, you can clearly see the stability rockets firing at different times in different positions at different intensities as needed to keep the rocket stable. There is a brief moment in the video where the Grasshopper appears to lean ever so slightly at an angle and drift a bit, it's the best point to see the different thrusters firing with different intensities to stabilize it.

    I know this is not the first vertical take off and landing rocket tested over the years, but this thing is pretty incredible, and any entity can make it economically and commercially practical, it's SpaceX.

  16. Huh? Wuh? on Sarah Thee Campagna Makes Robot Sculptures (Video) · · Score: 2

    Ok, so I take a brief catnap, wake up and go check out slashdot where I see this story. I am now going back to sleep in hopes that I wake up for real, at which point I will return to slashdot and see that in fact this was never posted.

  17. Re:This is like a creepy social experiment on Google Preparing "Google Mine" For Organizing and Sharing Your Stuff On Google+ · · Score: 1

    I could not agree with you more. I ditched facebook 2 years ago after the realization that it was a moral cesspool. All other forms of 'social networking' I was already avoiding. I do have a g+ account but I never use it -- besides, doesn't everyone on the planet have a g+ account wether they know it or not? I have tried to explain the situation to others with wording very close to yours, and with a few other points. The problem is, the more people get wrapped up in social networking in general, or otherwise all things google, the more distracted from reality, and overall intellectually dense the become, therefore becoming harder to reach.

    Don't even get me started on ingress... I have nearly lost real life friends over this google social networking information gathering so called game.

  18. getting all sentimental on Citrix Founder and Key OS/2 Player Ed Iacobucci Dead At 59 · · Score: 1

    I still have a boxed copy of OS\2 Warp, and probably an old enough computer somewhere around here to run it. As recently (recently... yea right) as 2000 I worked for a company that maintained old IBM mainframes running system 390. It was always fun to watch engineers crack one open only to see that there was an OS/2 workstation crammed in the middle. I think I just might take it for a spin as a tribute.

  19. RTFA Before Posting Please on Best Buy Recalls MacBook Pro Batteries · · Score: 2

    I'm going to say it right now: between the sensationalist and misleading summary (missing a slightly important point), and what the actual article says... this is going to be one giant "go RTFA fest" as the apple haters jump to conclusions and don't read the article.

    I'll give you a hint: why would Best Buy and not apple be doing the recall?

    Nothing personal against apple haters, my best friend is one. All I'm saying is, for a site where people often go off of the summary, without RTFA, this is a complete and total setup.

    I love you Slashdot, I've been here under one account or another since day one. Sometimes I think your editing is actually based on keeping me sentimental. Kisses.
