There is no denying that the 5s is really fast. However, in everyday use, does it need to be?

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.

Last month was the last month my ISP (Mediacom) was not limiting bandwidth. They give different amounts for different plans. For the 20Mbps the limit was 350GB. We are Netflix and Amazon prime video and Hulu junkies here, and last month I hit 420GB. The extra charge, assuming I use the same amount would have been $20 more per month. I opted for the 50Mbps package that cost $20 more, and also comes with 999GB

However, I would have been happy staying where I was, therefore I think they do not give enough of a cap.

By the history of large government IT projects, this is pretty well normal. The DOD, IRS, and just about every large department has had anything from minor to major disasters when setting up or updating systems.

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.

I have been looking at the IP v6 specs for enterprise level hardware, top of the line products from Cisco and the likes. The last I check, a few months ago, the accelerated routing on their top of the line Layer 3+ switch had about 1/2 the aggregate routing for IPv6 as it did IPv4, and older hardware is much worse.

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 guess you have not been looking at any reviews for the 7000 series then. The 7000 series cards are not winning on performance/watt except on OpenCL now, but are better for the performance/cost in every level. Check out Toms Hardware Best Graphics Card for the Money for this month, and pretty much the past couple of years, and AMD comes out on top in almost every category. Also, there are generally no Radeon specific features such as PhysX, but that is because Nvidia owns PhysX. And, as far as absolute performance in all categories except the very top ($400 plus range), AMD quite often is higher than Nvidia. Compare the Radeon 7850 to the similarly priced and recently release 650 ti. Take off your green colored glasses and take a look at what the current video card situation is.

As ericloewe said, AMD is more than competitive in the discrete card market. If you check out the tomshardware.com best buy for the price range for video cards, almost every month AMD cards dominate. For example, take a look at the recent 650ti launch for Nvidia. It came out at a price of $150, while the Radeon 1GB 7850 is currently at $160, about 7% more, but has roughly a 15-20% performance increase. The reason Nvidia is ahead is first that there is a perception of being better made by fan boys, and also, that Nvidia throws a LOT of money at developers to make games "Made for Nvidia" (I don't remember the exact phrase actually), which includes PhysX. I have met quite a few people that for no good reason refuse to buy AMD/ATI cards, but slavishly get Nvidia, even when they would be better off financially and performance wise with an AMD. And, AMD is normally many months ahead in releasing next gen cards. CPU wise, especially with their APU's for low end machines, they are also very competitive for a light gaming machine. Their latest APU was about twice as fast in games with better game support than the Intel HD 4000 on a core i7. CPU heavy things, the Intel chips were faster. However, I know a few people with laptops with the AMD A8 APU's, and they do not notice any everyday lag, and they can game on a laptop that has discrete video card performance in a $500-600 laptop.

I would like to disagree with the premise that not learning math facts is not important. As a person who has taught College Algebra to many adult non-traditional plus traditional students, I saw a very large correlation between those that did well and those that had the basic math facts down. The problem is that they may get the algebraic concepts without a problem, but get hung up on the arithmetic, and therefore still do not get problems correct. I know it is a correlation, not a causation, but at least from my observations the fundamentals and knowing the tables are important.

I think part of the problem also is the ridiculous requirements put into textbooks by some of the states. Some locales have required multiculturalism parts of classes, even something like elementary school math, which should be pretty much a fact based class.

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.

I know that CDMA is an older standard, however, from what I remember it has always had better voice quality and tower transfers than GSM.

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.

The problem with a 4k screen is not the price, it is the usefullness of it. There are charts out there that show the limits of our vision at different distances. A 4k screen would have to be huge to have a noticable difference in clarity at 3m for most people. I lookup up on Wikipedia the optimal viewing distances are for a 1080p screen, and for a 55" like listed above, the optimal viewing distance for 1080p (limited by human eye resolution) is 2-5m. For a 4k screen, it would have to be closer, and there was also noted in that article a mention that being too close to big screens can cause motion sickness.

I think for most people, a 4k screen is way overkill unless you have a HUGE (I would say 100" or above) screen.

Former eBay CEO Meg Whitman is poised to be named CEO of Hewlett-Packard later today after the markets are closed, said multiple sources close to the situation. The full board of HP, which is meeting today in Silicon Valley, has not officially voted on move and the situation could certainly change, sources said it is nearly a done deal.

I live in Illinois, and we have zero in the way of education as a second career without getting a full education degree (my BS is Electrical Engineering, and started grad school for Secondary Ed. Physics and Math). I have been teaching basic networking, college algebra, and intro to stats for over 10 years at a couple of small tech colleges, in addition to other systems admin work. I know more about applied math, physics and computers than any teacher in my relatively small district, yet, I can't teach.

When I left grad school due ot personal issues with less than two semesters left. I needed one methods class for teaching, 6-7 (don't remember exactly) classes on history of education and Ed Psych, three 3rd world cultures classes, biology, poetry, American and Illinois Government (yes, the exact same tests I took in High School, but I need to take a class on it anyway) and I don't remember what else. By the time I was done, if everything was done as an undergrad, I would have had a BS in EE, Math, and one class away from a Physics degree too. Yet, Illinois says no way.

Until education requirements are less politicized (and I realize Illinois is one of the worse in that category) and truly qualified people can teach without the BS, you will not really get the best teaching.

One last thing, we really need to get back to fundamentals. Drill drill drill on math, make sure they can write a sentance, paragraph and have an organized thought. Calculators are not needed until you get to roots, exponents, logs, and trig functions. Make the kids have the basics memorized and MAKE THEM THINK AND ORGANIZE!!
