A few years back Prague public transport tried something similar. They attempted to convince people to stop standing only on one side of the escalators. The reason was completely different. When people stand on one side, then this side is being worn out more than the other one. This was causing some troubles with servicing escalators. Apart from that I don't see any problems with allowing people in a hurry to walk/run the escalators. Especially when there are no stairs to run around the problem. BTW: if you walk on escalator, then you are always faster than someone on stairs:). If it comes to question of capacity, then it surly will win standing on both sides. But life is not always about maximum capacity.
No web doesn't work great. You probalby missed the information that IP addresses are exhausted. It means that there will be no new websites using IPv4. What exactly is the rest of the internet? You can't use it. You can use only limited part of the internet that has public IP addresses. The rest is hidden to you.
The internet works the way it is now not because users wanted it. It works the way it is because there are so many limitation thank's to NAT's so it is almost impossible to establish direct communication.
And for those who think tha NAT is security feature. Just set simple rule on your router equivalent to NATing:
OUTBOUND: allow all
INBOUND: deny all
It is even better (stronger), because you can't bypass it by NAT punching techniques. And if you need inbound connection, just allow that one in FW instead of port forwarding. It is not more complex than with NAT.
Unfortunately your approach brings one important compatibility issue. It is code - programmer compatibility. When you use STL or other standard library you can bring a new programmer to your project and he would't have much problem to understand the code. But don't use it and the new programmer would have to learn not only your code but your super highly optimized containers too. And I bet that your library wouldn't come with as good documentation as STL.
This really sound more as parents fail than anyone others. Especially Facebook. Parents should teach their kids to come to them when something like this happens. And if it happens then help them resolve the problem.
The fact that bullying messages are posted on social netwrok sites can be used as easy evidence against bullies. Just remember how it was before all the electronic stuff wass available. The bullies met you somewhere and threatened you. And you had nothing to prove that he was threatening you.
Nowadays you just pulls out message from your phone, e-mail, or whatever way was used and goes after bully. The problem is how it will be handled. Usually reporting bullies will backfire at you. So you should be prepared for that.
Just one question. How did 14 year old get drunk in the first place?
I have been hearing all this hype about how innovative online classes are, how this will change teaching, how we might not have colleges any more because it is so revolutionary.
Then you have been hearing it wrong. This kind of education is not going to make current education obsolete. It will just complement it. If you look at reasons why Sebastian Thrun left Stanford, then you might be surprised. The reason why he left was partly due to the fact that after he started teaching online AI class, then his usually packed classes at Stanford were suddenly empty. And when he asked his students why they don't come to see him while they pay big bills to be able to, the answer was surprising. I quote freely "Professor we rather like you on video. We can pause you and rewind you back."
You might also find a talk by Salman Khan, who made a bit of change in the learning field too. Just by using the tools like prerecorded classes you as a teacher can spend more on discussing stuff with students rather than talking to the room. And this is the point where I see biggest added value. Not mentioning that now are such lectures available to people like me who are long time out of school, but want to learn something new.
The one with longer delay will always win. Or if the time between the two machines will be short enough, then I expect the game will be degraded to paper - paper, because both machines would assume that other hand is being left in rock position, so it will transform its hand to paper.
The question is whether it would be even possible to play at all. The problem is that currently it is programmed to follow human player's hand. So if two machines are put against each other, then both will wait until the other one makes move and thus waiting indefinitely.
Just consider it a demonstration of very fast real time pattern recognition. But wait a moment don't we have a kinect for these kinds of tricks?
And what technology / service will that old e-mail replace?
- I haven't seen any replacement for encryption / digital signatures
- I still didn't figure how to mark what I have read and what not on services like FB or G+
- I haven't realized how to mark a post for immediate response of for getting to it later
- I haven't realized how to move a message to specific place so I can use it for reference later
- I haven't found a way to setup my own / corporate server, so I can be sure that my business will continue in case such service will go under
But what I have already learned with e-mail.
- its delivery is almost instant like any other service
- if I need it, I can work with it offline (on the plain, train, ship,...)
This shouldn't be a problem. This technology is primarily meant for highways. And as long as my memory goes. I didn't seen anyone crossing it. Except from some crazies and then it is safer to stop whole train.
But it might assist even in the urban areas. How often it happens that driver in one lane lets you walk across and in the next line is driver speeding up and almost driving over you. Just to stop on red light in less than 50 meters.
This is done to reduce revenue loss from piracy. Just imagine what sometimes happen. You go and see movie poster saying that it is premiere. You say to yourself, hey it might be good movie. But then you think. Wait a minute, what a premiere, it is the movie I have downloaded a couple months ago. OK, but it wasn't bad and I almost forget what it was about. I will go and see it again. And you go and it feels like watching those old movies with Charlie Chaplin. Studios make their profit and you feel good because you have seen that old forgotten movie again.
From TFA:
Will the certificates be awarded by Harvard and/or MIT?
As determined by the edX board, MIT and Harvard, online learners who demonstrate mastery of subjects could earn a certificate of completion, but such certificates would not be issued under the name of Harvard or MIT.
Producing, distributing and watching child porn is illegal. Period. So if you are accused of committing such crime, it could be seen as reasonable preventive action to prevent you from being alone with child. Any child. In your original post you mentioned sex with adults and that was thing I was mainly reacting at. It is not crime to watch porn with adults and adults only. However this guy was not arrested and even accused of any crime by police. And this is weird in this case. He has been banned from seeing his child only based on request of some people from child protective services.
I am wondering why they didn't just put only part of the captcha in each frame, so it would appear as solid text for humans when being replayed but it will appear totally different when you will look on separate frames. It might be just F in the first frame and underscore on second frame. This repeated will appear to humans as nice E. Yes, robots will adapt to it eventually. But it might take some time.
The easiest way is to just wipe the data and then forget about it.
You might also look for any clue about original owner and inform him about it. And of course wipe the data.
Just to help you in deciding I would like to share two stories of mine.
I have once found a USB stick. I checked it out and found who is its owner. He was glad that I returned it to him and paid me for it.
Another one is about external HDD I had. It died one day. But I had some data that was not in any backup. So I opened it and put the drive itself in computer. I have downloaded data and wiped disk. Then I put it back into its enclosure and returned it back. It was not simple as WD external disks have security sealed screws and some plastic locks. But after getting disk out of enclosure, then it was very easy to get data out.
It might be interesting, how the results will look like in larger installation with more rows of panels or more trees of panels. Given size of the tree I would expect more shadows at the tree model affecting results.
As noted by others, the tree is using more panels than flat installation. So it will be more expensive, more demanding on material resources and so on.
I made a second model that was based on how man-made solar panel arrays are designed.
Also if you look on the graphs that you can see peek values are higher on tree model than at "classic" model. So he has more panels on the tree or has significantly crippled standard configuration.
But there is one interesting thing on the tree design. It is more even distribution of the power during a day.
And what good is enterprise system if SOHO customers can't reach their IPv4-hosted web sites?
As you can probably see, the key to success in transition to IPv6 is dualstack for services, not for users.
If we will have all websites and VPN's and other services available via both IPv4 and IPv6, then there is no problem if users are on IPv4 or IPv6. They will just choose whatever is available from their ISP. And as more and more users will be IPv6 only, then content providers who stick to IPv4 only will fade out.
Just check with web/server hosting in your region to see how many of them already provide IPv6 connectivity. The content providers are those who should act now. Users will simply follow.
To be fair, you can still plug a modern Ethernet card into a 10Mbps Ethernet network and it will work;
You can't. Ethernet cabling also evolved during its lifetime. In the early stage it was using different cables with different connectors. Even your PS/2 keyboard can be connected to your USB port using reduction. But I don't know about any reduction from BNC to 8P8C. In this Wikipedia article http://en.wikipedia.org/wiki/Ethernet you can find photo of ethernet card with both connectors.
Your thinking is exactly what brought these guys into troubles. Just because some big company wrote some paper doesn't mean they are right and in line with your interest. Yes, most of the terms of such agreements are not negotiable, but some are. The great difference in having someone else to see the agreement or at least have a quiet time to study it yourself is that you know the risks and can evaluate them. Even if it might mean that you loose the deal. Sometimes it is better than bad deal. Your attorney is crap. He just failed on small threat from bank employee. He should list the pros and cons of the agreement and let the client to decide whether to sign or not. Or, eventually negotiate what changes are possible.
It is not necessary to have all users switched to IPv6. What we need is to have websites available over IPv6 so users who don't have access to IPv4 can access them. Then we can slowly start migrating end-users to IPv6 without worrying about loosing functionality. And this is where today's experiment is aimed. It is test if transition can be done without hacks like naming website ipv6.example.com instead of www.example.com as we are used to with IPv4.
What you tell to your users to be interested in IPv6?
Do you tell them here it is and if you want, you can run it? Or you tell them that when using IPv6, they will get public IP and their skype connection will be better as it will not need to use public relays?
Yes it also depends on the fact whether you actualy give your users public IP address or not. Those who are already behind NAT know what I am talking about.
No the problem is different. They are not going to switch to IPv6. They will support both IPv4 and IPv6. But there are some clients that prefer IPv6 for DNS queries while they don't have any connectivity over IPv6 to outer world. The quick and simple solution will be to disable IPv6 on those clients.
Getting it in your plumbing analogy. Water company says we can double pressure if you want. And you ask them to double pressure while your current plumbing is not able to handle it. But you still could ask them not to and they will be OK with it.
It might be interesting to see the study carried other way round. How many people with mental problems can turn into game addict. As it is said in the article "While these kids were more likely to have behavioral problems to begin with" there were already mental problems. But yes uncontrolled gaming made it worse or maybe just helped the problem to stand out. Same is true with anything you can imagine. Alcohol, cigarettes, food,... Should we ban these? No, we put some restrictions on availability of some of them depending on how much damage it can cause. Some of them are completely uncontrolled.
Parents should watch their kids if they don't have any problems. Not just checking if they have cold. Sometimes starting to play too much might be just indication that there is something wrong with kid's surrounding. Either in school or anywhere else. What you think will happen when kid is bullied? It will start avoiding people and eventually finds that playing games is much more satisfactory than playing with "friends".
And sometimes it is just big misunderstanding. As it was in movie Role Models.
As a coincidence I just read post on lifehacker on same topic. It contains more insight into problem.
They say that different parts of brain are involved when reading harder to read text and thus resulting in better understanding or remembering of written.

Why are people so persistent with attempts to bring NAT to IPv6? If you want DHCP functionality in your home network, then you have autoconfiguration in IPv6 and all your devices will get IPv6 address in the same way as DHCP assigned IPv4 addresses. If you have any device that supports IPv4 only, then you need to run your network dualstack to ensure that it can connect to its target. And to your complaint about length of IPv6 address. You don't have to stick with autoconfiguration. You can assign pretty any IP address you like based on prefix you get from your provider. So you can still have [your prefix]::1 address. On the other hand with ULA adresses (FC00::/7) you should use random generated interface identifier part of the address that makes it more random than static public IP addresses, where you will quickly get familiar with your prefix. And as you noted you will never reach public internet with that IP address. But in all cases it is much easier to use computer names and forget about IP addresses.
Yes, they will continue to run it in dual-stack. But instead of current practice where you need to enter ipv6.google.com you will just simply type www.google.com and will reach them via IPv6. It is similar for other sites.
You, who are like me stuck in IPv4 space mark June 8 in your calendars. As it might be day when you might not reach some resources on internet. It is due to fact how DNS will be resolved. Your computer will ask for IP addres and will get AAAA record but you don't have IPv6 connectivity so you will not connect. In better case it will fall back to IPv4.
