Back in the day, I/O was dreadfully slow. Think about 5 1/4" and 3 1/2" floppy disks and slow hard disks, and how long it could take to save a document. I can still hear the clunking and whirring in my head as the little activity LED blinks and the operating system grinds to a halt.
Now, with faster HDDs and even better SSDs, making "save" a separate, user-triggered operation doesn't make much sense. And with a jillion cores, you can easily offload the CPU work to do the saving to another thread so the UI isn't interrupted. Look at iOS - how many apps have a "save" button at all? It's expressly discouraged from the Human Interface Guidelines, and iOS users have been happily plugging along without it for years.
I think the real shocker is why applications still have a 3 1/2" floppy disk as the save icon. It's just an anachronism now.
I tried to get around this one time by spoofing my MAC with one from a library computer. THAT didn't go over so well. Since I was using the personal WiFi in my dorm room (stupid, I know), they knew exactly which network spigot it was coming from. Alarms went off all over their monitoring tools. Luckily I had a friend in IT who saw it, laughed, and told me to not do it again.
Also, sure it might be 37% efficient, but do you realize how SMALL the density of RF energy is? The Friis transmission equation gives you some idea: it decreases by the square of the distance away from the source, due to that power spreading out in a sphere. When you start off with only a couple mW of power and an omnidirectional antenna, there isn't much power left to harvest when these tiny receiving "metamaterial" antennas are even just a few feet from an access point.
"Oh no, a virus has replaced all my Fourier transforms with Laplace transforms!"
You'd be surprised. These types of viruses are spreading at higher frequencies. It's only a matter of time.
Now they want to point some sort of radar at a complicated source of ground clutter that's already difficult to detect and remove? I don't see how that's going to fly (no pun intended).

I have no less than four boxes overflowing with cables, adapters, hubs, game controllers, etc. These items are not yet ready for the trash and still need to be used on an infrequent basis. What organization systems do the gadget junkies of Slashdot have in place to easily store and access their peripheral paraphernalia?
