The problems with such rules, means the are plenty of work arounds,

In general booth babes are hired, because they know there are plenty of ongoers who still sexually are teenagers. And use them to attract people to their booth.

However what will happen they will have people dressed to fit the rules. However still be sexy, and they will flirt with the potentional customer anyways.

Insightful? More like hippy liberal corporation bashing.
Now this isn't some conservative rant. The FAA should be taking such things carefully, so not to cause problems. However, some of the rules are not focused on more agile aircraft development, where drones are involved there is less needs to verify personal safety, and changes to the drone technology shouldn't need as much screwenty. So unlike a Jet where they decided to change a component, as the safety of the pilot is a major concern, and such change should be completely reviewed. For a drone, just as long it fits in the recommended size and flight area it should be allowed more flexibility in changes without as much FAA review. Being that the overall risk of such changes is so small.

In general writing to RAM is faster than writing to the disk. However there are things that get in the way of both.
1. OS Memory Management: So you making a small memory string to a big one. So will the os fragment the string, when it comes up to an other systems reserved memory spot. Will it overwrite it (Buffer overflow), will it find a contiguous larger memory block and copy the data there. Will it copy and move the memory slots to a new location away from the memory. Will this be happening preemptively, or when the error condition occurs, will all this stuff happen with a cpu cycle that is not sharing with your app. Also if you are low on memory the system may dump it to the disk anyways.

2. OS Disk management: A lot of the same concerns that memory management has. However a bunch of small request is easier to find free space, then asking for a larger spot. So they may be more seek time.

3. Disk Caching: You tell the program to append to the disk. The OS sends the data to the drive, the drive responds back Yea I got it. then the OS goes back to handling your app, in the mean time your drive is actually spinning to save the data on the disk.

4. How your compiler handles the memory. Data = Data + "STRING" vs. Data+="STRING" vs Data.Append("STRING") vs { DataVal2=malloc(6); DataVal2="STRING"; DataRec->Next = *DataVal2; } You could be spending O(n) time saving your memory where you can be doing in in O(1)

Now sometime I do change my algorithm to write to the disk vs. handling it in memory. Mostly because the data I am processing is huge, and I much rather sacrifice speed, in order to insure that the data gets written.

Except for the fact that many of these representatives represent rural communities, where they need to travel miles to even see a local town government official, or police man. This stuff has limited impact on their lives. While the City Folk who see a Homeland security truck parked outside their home feel more threatened.
They rural folk are more likely to see the PA as something that affects other people.

It appears crazy at first. But it was actually designed rather well as to not have your hand move from the core of the keyboard.
As well vi was one of the first full screen editors. So a lot of terminals had inconsistent keys on the keyboard, you could only really trust the core set. The fact it was using the esc key was pushing it.

Overhead on the CPU and in terms of interconnect latency. Because USB is higher level, it incurs a decent amount of load on the CPU. No big deal for basic use, but you wouldn't want it for your main drive or the like. Also USB's latency isn't great, on the order of 100 microseconds or so. Fine for many uses, but high by SSD reckoning and not something you want time critical system components on. PCIe latency is so low you tend to measure it in cycles, not in time.

Also 20Gbit/sec doesn't cut it for some of the internal shit. Graphics and compute hang on 16x slots those are 16GByte/sec in the 3.0 spec (half that in 2.0) per direction (it is completely full duplex). That's 128gbits/sec. For all that it is still extremely performance limiting if you regularly have to use it to access system RAM.

Really interfaces usually are designed for purpose, and not everything is compatible. When you are trying to balance cost, speed, complexity of implementation, complexity of signaling, distance, etc, etc something has to give. There's reason to have PCIe for internal connections, USB for devices, and Ethernet for network, and not try to cram all that in to one bus that is not well suited to them.

These M.2 drivers are PCIe. It is a different slot form factor, but it is just PCIe.

USB would not be desirable for internal system use, too much overhead. It is well designed for the purpose it has but you wouldn't want it for everything.

There are reasons to want multiple transports, different ones are good at different things.

It went from "faster than matters" to "even faster than matters". All SATA drives are fast enough, you don't notice the difference between normal ones and ultra fast ones.. I have a Samsung XP941 (the "proprietary" drive that you can easily buy) and a regular 840 Pro in my desktop. You can benchmark the difference easily, but you don't notice it, at all, in day to day operation.

People where hostile to people with Cell phones in the 1980's, In college back in my day, if a student went to class with a Laptop we were hostile towards them. Portable technology takes a while to get into the culture.

  Google keeps telling us what the future is going to be ... the problem is that future is designed to profit Google. Well Duh! Google isn't going to try to push a product that will put them out of business?

In general Google Glass may or may not make it. However its failure doesn't mean the end. The Apple Newton failed too, from its experience and lessons learned it became the iPhone, and iPad.

The vast majority of students will never need to know how to analyse literature.
The vast majority of students will never need to know about world history.
The vast majority of students will never need to solve algebraic equations.

Learning to code, isn't about knowing the silly commands, but training your mind into solving problems by breaking them down into elementary instructions. It helps you understand the world and trains your mind into different ways of thinking.

I think we need to get off this GPA concept.
Right now students with strong in Language skills, get a higher GPA than students who has strong analytical skills.

By keeping the system, such students with stronger analytical skills, will not get credit for what they are good at and will penalized for deficiencies in language skills.

I was able to write code at 6 years of age, I knew more about science than most adults. However in elementary school, I was placed as a troubled student group, because my reading and writing performance was behind my grade level. Sure we had science classes, and a few other classes where I was excelling at, but they were pass/fail... So I was still tagged as the stupid student.
