Re:This is ridiculous.
If you want to get all strict-constructionist on this matter though, planes, cars, buses, and rail didn't even exist when the Constitution was written, so one could argue that there's no Constitutional protection when travelling by anything beyond horseback, carriage, or walking.
This argument doesn't make any sense, and certainly wouldn't to a strict-constructionist.
Either the Constitution was intended to cover any type of travel when originally written, or it wasn't.
If it was, then any type of travel is protected, because nothing in the Constitution authorizes the government to restrict travel.
If (as you argue) it wasn't intended to cover, say, flying, because it didn't exist at that time yet (silly, no one really argues that but let's go with it...), then still, nothing in the Constitution authorizes the government to restrict travel via flying.
The fallacy you seem to be falling into is thinking that the Constitution needs to explicitly permit or protect a particular freedom (like travel) or else the government can do what they want in regards to it. The Constitution doesn't grant people rights and doesn't protect only enumerated freedoms. It enumerates specific powers for the government and reserves everything not specifically granted to the States and the people.So if the Constitution doesn't apply to something, then the Federal government doesn't have any authority whatsoever in regards to that something.
In actual fact, the courts have ruled that any limitation on the fundamental right to travel must pass strict scrutiny. See a few hundred thousand links from Google.

Making Silent Running drones for gardening
A post from me to comp.robotics.misc in 1999 about Silent Running drones which spawned a thread with 32 messages:
https://groups.google.com/foru...
---
Anyone remember the drones (Huey, Dewey, and Louie) from the sci-fi movie Silent Running?Some links:
...They have always captivated me, and were an early influence in getting me interested in robotics and AI.
I particularly liked the scene where all three worked together to perform a medical operation.
I've long wanted to build some robots like these for gardening and maintenance. It seems to me that multifuncional drones such as those (with changeable end effectors) would be very valuable in agriculture, by reducing the need for pesticides and fertilizers through picking off pests, pulling weeds, and spot applying fertilizer, and by not compacting the soil like tractors.
Has anyone given any though to what it would take to make such drones today?
How much would it cost to build such a system (part cost, design time cost, assembly time cost)?
How long would it take?
How much could it lift?
How long would the battery (fuel cell?) life be?
How well could they be made to walk or climb stairs with today's technology?Anyone out there started such a project to clone these drones?
Any advice on where to find more information on their design, or maybe the originals made for the movies?
Would that design concept (one armed, collaborative walking robots, three feet high) now be considered obsolete (i.e. compared to the post model in Hans Moravec's latest book "Robot")?
Could a business case be made today for a company to build such robots? Or instead, would anyone be interested in collaborating on an open source design for robots that looked like those?

Re:Why focus on the desktop?
Free with $2000 purchase, fucktard. And you can't downgrade. Moving from Snow Leopard to Lion was my greatest mistake. Up to that point I had been a satisfied, kool-aid drinking, cash-spending Appletard.
1. You missed my comment about Hackintoshes. Plus, real Macs start at just under $1k.
2. Lion, especially when it first came out, was apparently somewhat of a POS. I simply avoided it; because, apparently unlike you, I have enough experience with computers and OSes in general that I never install a new version of anything the minute it comes out.
Everyone is allowed to have a "meh" release once in awhile. Apple actually has a fairly good track record in that regard (MUCH better than Windows, where it is a common joke that you "avoid the even-number releases"). I'm sure Linux is no different.
And please tell me what kept you from re-installing Snow Leopard after a Drive Format? Or, better yet, from that Backup that Apple encouraged you to make (and which you could have done totally automatically if you'd bothered to use Time Machine)? I've personally seen Time Machine start with a completely bare HD and restore EVERYTHING to an EXACTITUDE, all with a couple of Clicks. You could have EASILY "Downgraded" using that method.
Oh, and a quick Google search reveals BUNCHES of Posts on how to downgrade from Lion to Snow Leopard. You obviously didn't even try... So, who's the '"tard" now??? -
Re:Faulty logic
Go type in your favorite search engine "DCMA bogus requests" and a treasure trove will appear. There are plenty of citations available to back my statement.
I'll give you a very easy starting point if you hate sifting data, assuming you really want to look. Alex Jones has had numerous take down orders, accounts cancelled, and content banned. I don't agree with much of what he says, but at the same time I don't believe that he should be censored. He's an easy one to find information on, there there are numerous other less sensationalist people that have similar stories.
GP stated that anyone receiving take downs is posting illegal content, and that is an outright lie. Google even publishes some of the bogus requests.
Do you think that the exponential growth in requests is all magically legit? Anyone that understands the basics of statistics should have a WTF moment by looking at this graph
These are not court processes with transcripts, but enough communications can be reviewed to determine that the majority of these are not people ripping off and sharing a song or movie.

Re:Big Data
So?
I used to run a big adult site. We wanted servers closer to the customers for speed. We made enough that we didn't really care about the connection costs. We'd put up server farms around the world where it suited our customers best.
We owned every piece of equipment in our cabinet or cage (depending on the location). The provider equipment ended at the fiber they dropped to us, and the power outlets.
Netflix was hosted with Amazon for a while. A couple years ago, they claimed to have started their own CDN.
Their own CDN site talks about putting Netflix gear out for free. So they are basically saying they want the free ride. No one gets rack space, power, and connections for free. The right thing to do would be to lease the space like everyone else does.
But hey, they're loving to cry about being treated unfairly. They are the loudest ones about it. Honestly, other than speed complaints that are usually a fault, not a conspiracy, I don't know of anyone else talking about the same thing.
It is possible that the world is ganging up on Netflix. It happened to Cogent, more than once. That was mostly they refused to pay on their contractual obligations.

Non-monetized platforms
however the former issue about videos "not being available on mobile" is not a problem while using the stock YouTube app.
It was some time ago when I used the stock YouTube apps for Android and iOS. I don't currently own a Wii U on which to test, but I have read a policy document stating that YouTube allows the partner uploader or a Content ID claimant to block videos from being viewed on "non-monetized platforms". Does "1-800-KIRBYCIDE", a popular fan video for "Doctor Online" by Zeromancer, play on Wii U?

Re:Time for medicare for all in the usa
Time for medicare for all in the usa also the million-dollar heart transplant is loaded with markup where you can likely go out side of the usa and pay way less for it.
also due to court rulings in favor of inmate care you can just go to prison / jail to get one as well.
http://www.cbsnews.com/news/pr...
Boy, is that ever the exception that proves the rule. In order to get a heart transplant somebody had to sue the California prison system for him.
If they didn't want to pay for it, they could have released him on parole. He was sentenced for burglary and robbery. A patient with heart failure isn't going to be able to commit any more burglaries and robberies. He'll be lucky if he can walk around the block.
Despite this unusual example, prisoners have some of the worst health care in the country.
I read a series of articles on prison health care by Andrew Skolnick in the Journal of the American Medical Association in 1998 http://www.aaskolnick.com/new/... and I've seen dozens of articles since then to show that it hasn't gotten any better (it couldn't get worse).
They were leaving diabetic patients to die in their cells without insulin. Dozens of patients died because doctors and nurses simply ignored them and didn't give them their regular medication.
Sue, you say? It's almost impossible for a prisoner or his estate to sue the prison or the private contractor in most prisons, Correctional Medical Services.
There was a provision in a lot of states by which a doctor who was convicted of sexually abusing patients or dealing drugs would get his license reinstated but limited only to treating prisoners, so many of the prison doctors had worse convictions than their patients.
Don't forget, a lot of these prisoners were in because of the war on drugs.
Journalists know that if you want to do a sensational investigative story, write about prison health care. The New York Times did a series a while back:

As Health Care in Jails Goes Private, 10 Days Can Be a Death Sentence
By PAUL von ZIELBAUER
Published: February 27, 2005Brian Tetrault was 44 when he was led into a dim county jail cell in upstate New York in 2001, charged with taking some skis and other items from his ex-wife's home. A former nuclear scientist who had struggled with Parkinson's disease, he began to die almost immediately, and state investigators would later discover why: The jail's medical director had cut off all but a few of the 32 pills he needed each day to quell his tremors.
Candy Brown died in September 2000, investigators say, when her withdrawal from heroin went untreated in this Rochester jail cell, shown in a recent photo.

Re:American car companies...
I started a post with the aim to thoroughly rebuke you and refute your claim. The first place I looked was a Google search for standard warranties which gives US manufacturers' warranties as about the same lengths as foreign warranties. Next I looked for how well manufcaturers actually stand by their warranties. The number of hate articles and lawsuits over various foreign and domestic manufacturers' warranties seems about the same. Cars still on the road is another way to look at reliability. After some research I have come to the conclusion that the oldest cars longevity isn't related to quality of manufacture but rather dedication of the owners, older common cars are foreign -- but that doesn't count toward my point since the increase in US manufacturers' quality is relatively recent -- and common cars aging on the road today are about the same across country of manufacture.*
The late 1980's and early 1990's saw Honda et al. Eating Ford's lunch and US manufacturers' advertising focused on brand recognition. Later ads focused on features. Since this is a case of competing against quality with features (and because Tesla) I'm not even going to contest that US manufacturers ever fell behind on features.
Foreign cars still dominate in the mileage category but that alone is insufficient to state in the grand sweeping way I did that US made cars are inferior.
In short I stand corrected. US manufacturers have fully caught up with foreign makers in most categories of vehicle quality.

What triggers Gmail to require mobile #
Reports I've read say it may be correlated with where you connect from. Some IP addresses are more likely to make the Gmail sign-up form treat "mobile number" as required, especially for someone who doesn't already have a secondary email address. Conjecture, but public places that send a whole bunch of account registrations from one IP, such as a restaurant or a public library, may be more likely to make mobile number required. Or it might be based on spam reports from an ISP. I'm only guessing, but here's an anecdote. I know Yahoo is strict about requiring a mobile number, and people report having to "pay their dues" to a cellular carrier to create an account.

Re:You can't regulate human nature
More an this topic. There is also perhaps an issue with labeling people "trolls" or "bullies". Most people can and will act differently in different contexts. There is also a continuum of human behavior all people engage in. In the case of "bullying", it is fairly human for people to banter back and forth and insult each other in what might generally be seen as healthy relationships (as Izzy Kalman suggests). So, bans on all perceived insults in a classroom or workspace may actually be counterproductive by ramping up the stress of the situations when they do happen for whatever reason.
And it is all too easy to call an unpopular opinion a troll. Also, for the person responding to the "troll", it is hard to know sometimes when some person saying a rude thing or clueless thing or factually incorrect thing might benefit from a response. Or even to say someone has an agenda when they maybe just made a mistake; a recent example of that:
http://hardware.slashdot.org/c...I do feel we need better tools for online discussions though, including being able to tag message after-the-fact by crowdsourcing like Slashdot does. Here is one of many posts I've mode on that, this one when in 2010 someone reposted an email Adrian Bowyer wrote when he unsubscribed from the RepRap list:
https://groups.google.com/foru...Still, there are no doubt people out there at any given time trying to hurt others or do shocking things purely for the shock value for whatever reason. It is hard to know what to do with the worst sort of trolling, as mentioned by someone else in another comment:
"Robin William' daughter gives up social media due to abusive messages"
http://www.japantoday.com/cate...Such really awful messages probably comes in part out of the fact that the internet deprives people of social cues that would happen in face-to-face interactions. See also on progressive desensitization:
http://en.wikipedia.org/wiki/M...
"Mistakes Were Made (But Not by Me) is a non-fiction book by social psychologists Carol Tavris and Elliot Aronson, first published in 2007. It deals with cognitive dissonance, confirmation bias and other cognitive biases, using these psychological theories to illustrate how the perpetrators (and victims) of hurtful acts justify and rationalize their behavior. It describes a positive feedback loop of action and self-deception by which slight differences between people's attitudes become polarized." -

Re:Remove old apps.
There are some niche apps which were updated a long time ago and yet continue working well. For example an SSH client https://play.google.com/store/... (this is Android, but still). There are some clones of this app, adding some extra (perhaps unneeded) features, and either display ads or require payment while the original app is completely free and open-source. If it works well even on the latest hardware, should it really be removed if it's no longer updated and does not generate as much cash as the clones?

Google & BING show my stuff still... apk
They know it adds security, speed, reliability, & more for users online: You're welcome to disprove this point by point in fact on that note:
APK Hosts File Engine 9.0++ 32/64-bit:
http://start64.com/index.php?o...
(Details of benefits in link)
Summary:
---
A.) Hosts do more than:
1.) AdBlock ("souled-out" 2 Google/Crippled by default)
2.) Ghostery (Advertiser owned) - "Fox guards henhouse"
3.) Request Policy -> http://yro.slashdot.org/commen...B.) Hosts add reliability vs. downed/redirected dns (& overcome redirects on sites,
/. beta as an example).C.) Hosts secure vs. malicious domains too -> http://tech.slashdot.org/comme... w/ less added "moving parts" complexity/room 4 breakdown,
D.) Hosts files yield more:
1.) Speed (adblock & hardcodes fav sites - faster than remote dns)
2.) Security (vs. malicious domains serving malcontent + block spam/phish & trackers)
3.) Reliability (vs. downed or Kaminsky redirect vulnerable dns, 99% = unpatched vs. it & worst @ isp level + weak vs Fastflux + dynamic dns botnets)
4.) Anonymity (vs. dns request logs + dnsbl's).---
* Hosts do more w/ less (1 file) @ faster levels (ring 0) vs redundant inefficient addons (slowing slower ring 3 browsers) via filtering 4 the IP stack (coded in C, loads w/ os, & 1st net resolver queried w\ 45++ yrs.of optimization).
* Addons = more complex + slow browsers in message passing (use a few concurrently & see) & are nullified by native browser methods - It's how Clarityray is destroying Adblock.
* Addons slowup slower usermode browsers layering on more - & bloat RAM consumption too + hugely excessive cpu use (4++gb extra in FireFox https://blog.mozilla.org/nneth...)
Work w/ a native kernelmode part - hosts files (An integrated part of the ip stack)

Re:meh

That article also shows a picture with a partial glimpse of the entrance. This article from the same site has a picture of the lion, and the video down below is basically a slideshow of pictures of the tomb site. There's another article here with another exterior picture. The site of ancient Amphipolis is here, on the land surrounded by the river (you can zoom in and see the ruins of the acropolis).

Re:This is going to end so well for them!
Neither of those things see any appreciable improvement by going from 3G to 4G. The limiting factor when loading webpages is very rarely available bandwidth (measure how big a particular webpage is and how long it takes to load and you'll find that it's nowhere near your pipe's capacity). 4G would help Youtube only if you could somehow fast-forward through each video.
4G LTE provides download speeds up to 299.6Mbps.
The size of the average web page is 1.3MB.
Youtube pushes at most 6Mbps (and that's for 1080p video).
Are you suggesting people should be hopping onto 4G LTE networks not to torrent, but to watch fifty 1080p Youtube streams simultaneously? Or maybe because they can't afford to wait 371ms for the average web page to load over a 3G link (if bandwidth was the limiting factor)?
4G LTE is no measurable benefit in either of the two scenarios you set forth. Therefore, that's not what 4G LTE data plans are for. Unfortunately, we don't all know that. -

Where do they get 2.2 hours from?
The article makes it sound like it doesn't matter what size or mass.
Parameters: Radius 650m, Circumference 4084m, Period 7560s, Speed 0.5157m/s, Mass 2.1e12kg
Calculating Surface Gravity = 0.0003315m/s/s.
Centrifugal Force = 0.00040915m/s/s
While that relates to the orbital speed calculated for the mass and radius of 0.4642m/s, it is far less than the escape velocity of 0.6565m/s. So how far out would it go?
The numbers are so small that if you take the speed they are moving of 0.5157m/s tangental to the surface and point it straight upwards and accelerate it with the gravity of 0.0003315m/s/s then it would come to a stand-still in somewhere over 1600seconds at a height somewhere over 800m and fall back towards the asteroid.
I don't know the maths to figure out the exact values since they vary so greatly with distance, but the difference in centrifugal and gravitational force is only 0.00007765m/s/s. That means that something weighing 100 TONS on earth would have a net upward force of about 1.6 pounds. Of course you can't treat the asteroid as discrete frictionless atoms. What holds a dirt clod together overcoming the full force of earth's gravity to maintain it's shape?
So if you were attached to the surface and dropped a rock it seems to me that it should continue upwards and orbit the asteroid at some altitude. It doesn't surprise me though that since dust can stick to my ceiling and ceiling fan blades even when they're whirring around that this asteroid can stick together.

It doesn't surprise me though that since dust can stick to my ceiling and ceiling fan blades even when they're whirring around that this asteroid can stick together.

Where do they get 2.2 hours from?
The article makes it sound like it doesn't matter what size or mass.
Parameters: Radius 650m, Circumference 4084m, Period 7560s, Speed 0.5157m/s, Mass 2.1e12kg
Calculating Surface Gravity = 0.0003315m/s/s.
Centrifugal Force = 0.00040915m/s/s
While that relates to the orbital speed calculated for the mass and radius of 0.4642m/s, it is far less than the escape velocity of 0.6565m/s. So how far out would it go?
The numbers are so small that if you take the speed they are moving of 0.5157m/s tangental to the surface and point it straight upwards and accelerate it with the gravity of 0.0003315m/s/s then it would come to a stand-still in somewhere over 1600seconds at a height somewhere over 800m and fall back towards the asteroid.
I don't know the maths to figure out the exact values since they vary so greatly with distance, but the difference in centrifugal and gravitational force is only 0.00007765m/s/s. That means that something weighing 100 TONS on earth would have a net upward force of about 1.6 pounds. Of course you can't treat the asteroid as discrete frictionless atoms.

Re:Oh man
Agreed, projecting on the visor like a fighter pilot helmet would be the best IMO. That way you can flip it up and it's not in your face if you want. Plus the visor is bigger and a better distance from your eyes than a google-glass-like window. You also would have more real estate for projecting information and telemetry data. And both eyes could then see it instead of just one.
I'm still waiting for this feature in cars for the windshield. Heck, my 1997 Pontiac had a cheap HUD that displays the speed and radio stations on the front window, why aren't we putting GPS nav and other information projected onto the front window by now. It's freaking 17 years later (from when my car was built) and there are STILL only a handful of cars doing this today, most common being the Corvette. Even the ones doing it today are still only putting a couple pieces of info on the window, same as my car did 17 years ago (speed, radio, and maybe what gear your in?). With tech being cheap today, I want this as an option on normal everyday cars as well (obviously as an option, so your not forced to buying it).
How cool would it be to have a HUD version of GPS of where you need to go overlaid on top of what you are seeing, or have some augmented reality street signs projected as you drive around an unfamiliar city. Add in your speed and a couple other car operating status displays, maybe a rear or side camera views to help with lane changes, and you got some useful information that you don't have to take your eyes off the road for. You could even do a night vision/FLIR front cam projection, so at night, you can see better (like Cadillac did years ago), except projected in front of you.
This would have to be way more safe to have this information transparently floating in front of you that needing to look down at a dash mounted GPS, or at your cluster, or at your radio when changing channels etc.
