There is a shortage of plumbers, electricians, welders and other skilled trades people due to the extremely low number of people going into the field. Here is an article describing the problem
What I am saying is that we need to get a balance. Don't dump everyone into trades. Put more people into trades, and less people into college programs that have little to no workforce demand, and/or help the people that drop out of college. It is a societal problem that has made way too many people, especially in major urban areas (talking to you Chicagoland) feel that trades jobs are beneath them. Just because I have a BS in Electrical Engineering means I know how to automatically safely wire a house (though I could read up on it) or do a good job doing it. We need skilled trades people and not have the people driving their luxury cars look down on those people.
The problem is that the trades are totally dismissed by the school counselors. We don't need so many people in traditional colleges. We need more people in the trades. Another example is in lower level IT. Basic help desk and level 1 support people need vocational training, not a BS or BA. We need to re-align higher education.You do not need a BS in CS to maintain a network.
I just got a Galaxy S4 ($50 on Amazon) and I have had zero lag in anything I have tried. Is the 5s faster, yes, is it noticeable in everyday use, not really. Just like with everyday use of desktops, the AMD A10 series is plenty fast for general desktop use, even though in benchmarks a Core i5 smokes it. However, unless you are running something very demanding, which most people don't, they won't see a difference.
Also, I like being able to have a spare battery and put in an SD card to add memory without Apple charging insane upgrade prices.
However, I would have been happy staying where I was, therefore I think they do not give enough of a cap.
I think too much of this is due to government bidding requirements that put too much emphasis on who you know more than what you know. I have seen too many stories where competence is the last thing looked at for contractors.
Until the hardware ASIC's are acellarated as much for IPv6, I think businesses will lag unless they need to use IPv6 due to contract requirements (military and the likes). Why would they pay more for modern hardware that is slower than what they have to adopt IPv6 when IPv4 is satisfying their needs, even if NAT is a gimped solution. It still works, and is pretty fast.
I live in Illinois, and I know my children's books are not up to the level of what I had 30 years ago. The books seem scatter brained with forced examples of what the states want put into the books. Also, the forced lack of focus on the fundamentals has gone a long way towards lowering the ability of students from the US to compete in a global academic environment, especially in the sciences and computer fields. Another item is what is wrong with timed drills, and letting students know that the world is not equal and that some people are better and faster in math than others. Welcome to the real world! I am not saying advertise who is the best, but don't stop doing timed tests and drills because some helicopter parent is complaining that their snowflake did not get the highest possible score. A friend of mine is a former principal at an elementary school, and he said that the biggest number of complaints he had were from parents who thought that it was traumatic for their children to not be able to complete timed math fundamentals tests.
Yes, the textbook manufacturers are sleazy and always trying to sell the new latest greatest edition, but don't forget some of the ever changing junk they have to put in to make the politicians happy in the big states (thank-you California and Texas). Let the experts decide what needs to be in an effective textbook, not the politicians.
The one big advantage of GSM is the use of SIM cards, and that simultaneous voice and data were possible. CDMA also has better spectral efficiency than TDMA used by GSM. Check out Wikipedia's article on it and look at the efficiency of the latest CDMA vs GSM standard.
Don't act like the carriers stuck with CDMA to be dinosaurs. It actually was , at least for voice users, the better technology.
I think for most people, a 4k screen is way overkill unless you have a HUGE (I would say 100" or above) screen.
