I don't know about anybody who claims to be a network engineer these days other than my peers, and all of us have been through CCNA, and you can't pass CCNA if you don't know that, and a lot more.
All of that goes beyond the realm of networking to be honest, with the slight exception of cryptography. As far as cryptography goes, you don't bother with that until you are at a more advanced level, and even then, you only need to be familiar with the names of the algorithms and the general purpose of each.
Most of what you are talking about goes in the area of computer science, and networking doesn't necessarily include computer science, and likewise, computer science in itself doesn't necessarily include networking.
I haven't read any details about the Stanford one yet, but the Cisco Network Academy I went to starts you from scratch. No need for programming, no need for understanding memory (though I am a novice programmer, the other students who had no knowledge whatsoever picked it up fine.) By the time you're done, you can easily count in binary up to 8 bits in your head.
I agree, Cisco has overall done a very good job in setting up their education program. I've already had on the job experience, and nearly all of what you learn is applicable to every vendor. I've even worked on brocade and HP equipment that looks and behaves remarkably similar to Cisco's IOS.
I've learned almost all I know about networking from the Cisco Network Academy offered at a local community college. Part of the course material is to learn OSPF pretty extensively, even going as far as to explain the differences in how it handles single access or multiple access, and in doing so how the DR and DRO elections work.
There is a fair amount of coverage on EIGRP, but I would say they teach both about the same. The teacher plainly told me that you never see EIGRP in a mixed environment. However on the job, I have actually used EIGRP. What I found shocking while on the job though, and they don't teach this at the network academy, is that there are other vendors who fully implement CDP, such as brocade, netapp, and HP, even though there are other non-proprietary standards around like LLDP. Granted you'll generally turn off CDP for security purposes, it is nice thing to have once in a while.
But most importantly, we did go over IPv6, although not extensively. We went over the packet header (simpler than IPv4, actually,) EUI-64, routable vs non-routable adresses and a few other things. The majority of the concepts from IPv4 (mainly subnetting) translate well into IPv6 though.
One thing to keep in mind though, is that not all Cisco Network Academies are created equal, just as not all colleges are created equal. There's a college called Gateway nearby that has notoriously bad teachers which won't even allow the students to cable their own routers (they say they might break them) and won't allow them to make their own cables (they say it creates a mess.) The one I went to for CCNA (and am going to for CCNP) is remarkably good, enough to the point that recruiters around the state recruit from there. Not even just from the Cisco students, but from the Linux and Microsoft ones as well, and soon they are adding EMC/vMware to their catalog.
Having said all of that, I can understand why some schools won't teach much IPv6, namely because in spite of it being around for so long, nearly all corporate and small business networks (where the vast majority of students will work) don't even touch IPv6. I could see maybe if you were working for an ISP or were working on some nationwide project, but that doesn't happen very often.
Well, it happens all the time to lots of words, just part of how languages evolve. Nowadays, for the old meaning of awesome we use different words or idioms, e.g. unreal or mind blowing.
Actually there are some links in TFA where they mention that after 500 feet, the light will have spread to a six foot radius. Further, when it hits the plexi glass of the cockpit, it scatters which illuminates the entire cockpit with a rather blinding light.
They are not saying that it is epidemic, they are saying that it is becoming epidemic. If you follow a few links from TFA, you'd see how the FBI has been documenting that the number of recorded incidents has been rising exponentially ever since 2006.
You're talking about much more than airports here. You'd also necessitate removing homes from hospitals as well since they use helicopters for emergency transport, and hospitals by their nature are near residential districts. This would also include police helicopters that fly at low altitude when following suspects.
I used to live near a hospital, helicopters flew at low altitude over my house somewhat frequently. I just recently moved near a smaller airport, which kind of works out nice as someone in my household owns a small aircraft.
Not only the simultaneous connections (due to orthogonal signaling) but also due to its longer range and higher capacity in general. GSM being TDMA has a strict limit of 20 per tower and bandwidth usage is far less efficient.
I'd say within 18 months you will see "convertible" touchscreen Ultrabooks running Windows 8 Professional with 512 to 1024 GB SSD storage standard with the latest super-efficient Intel "Core" CPU's, and those will definitely be vastly better-selling.
Isn't that what the Surface tablet is aimed at? (not the RT one) It is basically just an x86 tablet that runs windows pro and has an optional cover that is also a flexible keyboard/mouse, so you could really use it as either a laptop or a tablet.
Honestly Android is the only OS I've seen that elegantly handles scaling to higher resolutions and varying aspect ratios. Hell, the SDK itself gives you many options to make sure your app scales well.
Owning an ipad 2 myself, I can say that iphone apps scale horribly to ipad, and apple themselves even had a blunder when they changed aspect ratios (lol letterbox phone.) It's no mystery why when they increased the resolution on the ipad 3, they had to evenly multiply from 1072x768.
Any competent mobile OS should be able to handle this. In todays world of very high resolution displays, desktop ones should as well. When microsoft decided "let's make windows work for mobile platforms" and created metro, they should have taken this into consideration, yet oddly enough, they didn't.
Linux isn't much better though, in fact its worse in some ways in my experience. For some reason I always run into major problems with font scaling in x11.
Infrastructure doesn't play much of a role. One thing to consider is say driving a long ways. Assume that there was a charging station within every mile; they wouldn't compare to gas stations. At a gas station, you can be in and out in less than 2 minutes from an empty tank to a full one. The Tesla Roadster on the other hand takes 3.5 hours to fully charge.
Not a huge deal if you are only going to work and back, but what if you want to take a longer trip, say from Phoenix to LA? A good third of the time spent traveling there will be spent just waiting around for you car to charge.
I don't know what christianity has to do with it (again, I am an atheist.) Though honestly, I don't get it how when somebody talks about what people have done in the name of islam, somebody has to come along and say "well look what christians have done here..."
If a christian does it, does that somehow make it ok if the muslim does it? I don't get it.
In any case, christians haven't deliberately flown any airplanes into buildings, executed civilians on a cruise ship, or bombed any subways in order to promote their belief system as far as I'm aware.
Well, in response to your thinly veiled ad-home attack, I can fill you in on a personal anecdote.
In k-12, I had crap grades, and other students regularly gave me shit. In college, I have a 3.9 gpa, have earned many scholarships, the other students are great to get along with (hint: zero tolerance for immature ones) and the teachers actually give a damn.
So tell me, am I a bad student, or does the public system just suck?
The thing with muslims is they consider any belief system other than their own to be unacceptable, so mocking theirs is fair game. However mocking islam is completely unacceptable.
If you read the qu'ran, it is full of stuff like this. Muslims may not lie to other muslims, but they are allowed to lie to non-muslims. Muslims are allowed to claim non-muslims as slaves. Sure not all muslims believe this, but it is written in their book. Don't take my word for it, read the qu'ran for yourself.
Also the idea that islamic terrorism is a result of poverty and lack of education is a farce. Osama bin laden himself was very rich, and had a college education. ALL of the 9/11 hijackers had college degrees, and could have gotten very nice careers if they wanted to. Al-Qeada's current leader is a surgeon.
The idea that muslim terrorists are reacting about being oppressed is also false. Buddhists have seen far worse treatment from the chinese, have been slaughtered in the millions, even had their land (Tibet) blatantly annexed, had certain forms of worship banned, and been told that reincarnation is forbidden. Yet where are the buddhist suicide bombers?
The problem with islam is what it teaches.
FWIW I am an atheist, and I see islam for what it is. Also, another poster above stated that nobody who has ever worn a uniform of the US military would say what I just said; well, once upon a time I wore such a uniform.

Sorry, I meant per channel, whereas CDMA doesn't have a definable limit.

This really isn't unusual, idle usually is off topic. You can set your preferences to ignore idle if you want.

Yeah I was wondering if I am the only one who doesn't know what a exactly a "CPU user" is. The terms CPU and computer are not interchangeable.
Don't forget that they also censor in the US from demands of the government; specifically in the form of DMCA takedown requests.

Hell, fuck all invisible men in the sky.
I think you misread what I said? I'm not saying I find it unacceptable, I'm saying muslims do (and apparently so do the hosts of the view.)
