Black holes aren't "infinitely dense" because that is ridiculous
You're misinterpreting the meaning of "infinite" here. You're assuming density measurement has an infinite value. Like "How many dollars are there?" Well, you could have any number of dollars from 1 to infinity. That's not how density is measured. Another type of measurement is "What angle is the corner of that triangle?" That could be anywhere from 1 to 359 degrees (rounding to whole numbers) It's kind of like a percentage. Infinite density would be like saying the angle is 360 Degrees. That breaks the triangle. The angle is effectively infinite. Mass, density, momentum, time, etc... are all treated like geometry when you get into relativistic effects. You can't exceed the speed of light because that to would break the geometry of the system. Once you hit the speed of light, you again are doing the equivalent of making one of the angles 360 degrees.
The "Triangle" of this system is Speed, time and mass. So for speed to exceed the speed of light and therefor be the "360 degree angle" of this triangle, the other two angles... time and mass, must be 0. Therefor time stops, and the moving object must be massless. Does that make more sense?
But that's exactly what they are saying. You need to differentiate. Blackholes are NOT singularities. A blackhole is the collection of phenomena and objects in an area of spacetime. It is believe that at the center of the blackhole is a singularity. What this new theory suggests is that there is not a singularity there, but instead that it just behaves very similar to one.
can some explain why information can't be lost? this is slightly confusing and that assumption makes it seem like they're building a lot of theory on a pretty shaky foundation.
It's actually not as mind bending as you might think.
Quantum mechanics is "Time Symmetrical" meaning that, the laws of physics work the same irrelevant of the direction of time. This is only at the quantum scale so real world stuff doesn't work so hot. But take a quantum particle falling into a blackhole... If the blackhole consumed it, destroying all information about it... if you reversed time, the particle would never exist, and never be ejected back into space. If, however, time slows as it approached the blackhole and the particle never actually crossed the event horizon... then if you reverse time, time would speed up and the particle would eventually be flung away.
This all depends on you accepting the standard model, and the current interpenetration of quantum physics. They are becoming more rock solid every day however, it would take some pretty amazing discoveries to break them.
You do realize there are several flavors of encryption, right? Microsoft SQL Server TDE is an example. You can login, perform queries, update data in any table, but all data is encrypted - it is - transparent as the name indicates.
That also ignores things like encrypted volumes, etc. Just because individual files aren't encrypted with unique keys, doesn't mean that encryption isn't there.
The data he updated was someones password. Wouldn't that concern you?;-)
Because the majority of the people getting CS degrees now-a-days have no idea what they are doing. And I don't mean, they just aren't good. I mean they barely even know how to type. I worked with a guy a while back that was given 4 projects in a row and did absolutely no work on them. I liked the guy personally so he felt safe in asking me questions... He didn't even know how to define a variable or call an Object in the Language he specialized in. And I've met LOTS of people like that. He was probably the worst, but the quality of people with degrees in programming is awful. I'm not sure if it's just because it's something really hard to test for or if cheating is rampant. But there is definitely a problem. Most of the people I work with that don't have a degree and had to claw their way up are a lot better than the people that have 4yr degrees.
Also, programming jobs don't pay crap anymore. Managers at McDonalds make about the same as entry level program jobs.
You've clearly never worked in security. You can never fully secure anything. All you can do is shift liability away from your business. You need to reduce the chances of a breach to the point that the number that occur and lead to lawsuits costs you less than the effort to make it more secure. You could technically require every customer to drive down to your main office in person and show ID before logging in... but what would that do to your business? Secondly, procedure is everything. How do people handle data? What is the process for updating a router? LDAP? the VPN? etc? 90% of security is writing bulletproof process. 9% are the people that follow that process. 1% is HR firing people that don't.
If you just hire "Security people" and expect them to act "securely" you're just asking for trouble.
If this order still stands, why hasn't the FCC fined practically every ISP under this rule? Plenty of ISPs were (and some still are) throttling YouTube, and I don't think I saw a single notice from the ISPs themselves about it. I would think that YouTube counts as a "certain type of traffic" for the purposes of this rule.
ISP's get fined all the time. The fines are not advertised unless the FCC wants to make a political statement. I suspect this press release is a shot over the bow of one or more ISP's over a particularly egregious case that may even be local and not on our radar yet.
Yea, we use a very expesnsive cloud service that per the contract is encrypted at rest and in transit. After 5yrs I happened to have a networking issue and did a packet capture on the stream... no encryption. So we approached them... "Encryption? No, we don't do that..." We explained that it was in the contract and they HAD to do that. So after 2 months they had to move us to a "Special" server and we were encrypted. I checked the packets again and we were at least encrypted in transit. A few months later we had another trouble ticket with them. One of their techs was working on it and explained how he logged in an edited the table raw to fix it. So I asked how he could do that if the data was encrypted. "Encryption? No, we don't do that..." ugh... so now we're supposedly "really" encrypted.
The problem with cloud services is they can lie cheat and steal with your data and there's nothing you can do about it. You can't verify it, you can't test it, and if anything happens to it you wouldn't have a clue. You're entirely at the mercy of the provider and as time goes on their internal staff can turn over, competence can wane, controls can get lax, and you'll have no idea any of that is happening.
People HATE windows 8 because they are trying to force a touch interface on it, most people do not buy touch montiors so it is less than intuitive.. now they want to make it even more touch oriented? unless they are going to send me FREE 27" and 40" 4K touchscreen monitors it's not going to be worth a damn.
STOP TRYING TO UNIFY THE PC AND TABLET/PHONE WORLDS! I am so sick of companies trying to do this, it's a failure an utter failure.
They certainly can unify the PC and Tablet. They just have to give up on the insane idea that the UI will be identical between devices. The mouse didn't work on a small screen so they put the touchscreen on my 52" TV?!?! Seriously, who thought that was a good idea?
This is a very easy thing to fix... XP/Win7 style desk for PCs, Android style for anything smaller than 10", Remote/MediaPC controlls for TVs. And... wait for it... Alt-windows key toggles between UIs for those that like different ones at different times. Eeegads! Am I the next Wozniak with my insanely brilliant ideas or what? Oh wait... no, it's just that obvious.
If I actually cared about the Government breaking into my encrypted files I'd be using a One Time Pad. It might be cumbersome, and it might flag it as actually important info, but if I really didn't want someone to have the possibility of breaking it then only a encryption method that cannot be broken with any amount of processing power will do. However, I don't have any need to worry about some trivial thing like are they looking at me today. I don't have that kind of secret to hide.
You should always be worried about the government breaking into your encrypted files. There is only 1 group in this country that can legally torture you and put you to death. Only one group that actually does that very thing on a daily basis. Irrelevant of their current laws and practices, it's in your best interest to protect yourself from their prying eyes. You've no idea what you're doing today that will be illegal tomorrow. Every device I own has some degree of encryption. Will that protect me if they target me directly? Probably not, but I certainly am not going to make it easy for them if it comes to that. Decent encryption isn't that hard, and just takes a few minutes of your time.
Righteous anger isn't always as Righteous or helpful as you'd originally thought. That's why we have a constitution, bill of rights, etc... To protect us from the whims of an angry fickle public when short term popular opinion may not be in the best interest of the long term health of the country. Amending the constitution takes a long time for a reason. DHS and other 3 letter agencies can only use 9/11 to subjugate us for so long... eventually the fear will fade, and get replaced outrage. History will not be kind to those that built, supported and continued agencies like the DHS and the NSA.
No-one that knows anything about mechanics would be impressed. It would be pretty sad if any sort of weather could hard your under-water RC boat. Even Babies have survived rides in Tornadoes after all.
It's an $800 phone Proprietary store (you can't install standard google apps and I doubt your old apps will move to this phone) Performance is about Equal or slightly better to existing phones you can get for $1 on contract like my HTC one(M8) or the Galaxy S5 Only new feature is "3D" which, like very "3D" offering in every other product to date, it's not actually 3D, it's fairly annoying, a gimmick and will get turned off within hours of getting the phone.
So you'd buy this why?
Don't get me wrong, I absolutely love my kindle. I shop on Amazon all the time and like it. The fire tablets were cheap when there weren't many cheap tablets out there. But this phone is DOA.
This sounds like a make-work project by the Chinese government to try to boost their economy. Construction is a huge business in China that accounts for a large portion of their GDP - that's why you see things like the "ghost cities" there, where construction workers built thousands of apartments and offices that aren't ever going to be used simply because the Chinese government needs to keep pumping money into construction.
Digging a 57-kilometer underground tunnel would probably put plenty of construction workers to work for a while - not to mention hauling in all the equipment, doing all the wiring and piping, etc.
At least they're doing something constructive with their projects for once. As fun as the empty cities might be for film makers and urban spelunkers they're otherwise a huge waste. Maybe we can get China to build a space elevator!
The lawsuit also rides on the fact that these people bought Android phones at a time when Google already knew (but was not telling anyone) that it would be changing its privacy policy. By being forced to replace their devices - which automatically had the new policy applied to them - the customers have been demonstrably harmed. In fact this appears in the paperwork before the battery drain issue.
Right, so Google will issue them a refund plus $5 for wasted electricity over the life of the phone and everyone will go on with their lives?
You've got that backward. One group can, at worst, buy porn with your CC number... the other, at worst, will fly you to a random country, torture you for months and then dump your lifeless corpse in the Ocean. I'm more concerned about the 3 letter agencies thank you.
So if you're sharing your wi-fi with the public at large and someone commits an "Internet Nasty" while connected via your router - who is criminally liable?
Who's liable when they roll into the parking lot of the local Best Western and do the same thing?
Making it public is what makes you immune. If it's not public, then you're verifying that all activity from your IP is your own. Making your connection free for others to use re-anonymizes your IP address.
Illegal use of your access point could have serious consequences (unless it somehow confers Common Carrier Protection of Interneting +4 which I'm unaware of)
And how many Starbucks owners do you see in federal prison?

who is throttling youtube?
hosting video content on the internet without paying a CDN or directly peering with ISP's is asking for trouble
Right, Google is very friendly with the ISPs. I doubt there is any throttling of Youtube happening.
If this order still stands, why hasn't the FCC fined practically every ISP under this rule? Plenty of ISPs were (and some still are) throttling YouTube, and I don't think I saw a single notice from the ISPs themselves about it.
