Depending on how twisted you are, caltrops are fun to play with, and they always land on their feet. Seems like it would be a pretty good design pattern to use.

Here is a delightful new feature I just discovered. On the previous versions of Apple's Mail app, in the trash mailbox, you could tap the "Edit" at the top of the message list, then the "Delete All" at the bottom and the confirmation popup from that button. Apparently that was too high a risk...

The floating keyboard is just a bit too small. I have this handwriting keyboard that came with an app, and it works ok, more or less, floating, but there is barely room for two words at a time, it seems to become stuck in place at the lower left if I am not careful, and sometimes it blocks me...

Instead of oval, they should go figure-8: if you set it up with a shallow-angle cross-over, cars would just be merging across each other, like a collector-distributor; you could maintain the high speeds and grandstand-viewability in a more terrifying event.

Which could end up

"I am a Leaf on the wind." Hmm. Maybe not so much. I think one of the biggest BEV hurdles may be charging station standardization. For 95% of use, home charging is awesome, but if we want to take those fun back roads in BFWyoming, knowing that the nearest compatible charging station is 120...

The upside for the broad EV market is that you can plug in at home and might rarely have to stop to recharge, thus avoiding that regular trip to the Esso. But why could you not do the same with H? Just install a system in your garage that could split your tap water electrically and feed the H...

Is it a car or just a jet/rocket engine with wheels?

Thing that confuses me is Crusoe. They had a VLIW (very long instruction word) architecture that I understood had some design similarities to Itanium, but they used it to emulate x86-32, and rather well, for a while. Intel could not make it work, but somebody else could, at least for a while...

Well, if it is Nazi iconography, perhaps it would be the ideal place to relocate our troublesome neonazis.

Minor nitpick: those are not spoilers, they are called flaps. Flaps alter the wing profile to increase drag and lift, essentially lowering stall speed so that landing can happen slower. Spoilers are a completely different thing that rise from the top surface of the wing to reduce lift (just like...

When you think about it, if you are landing in a crosswind, do you want your plane to be lighter or heavier? Seems to me that a heavier plane would offer better control. Of course, the downside to metal-air batteries is that, with current technology, they are not electrically rechargeable, but...

Propellers? We don't need no stinkin' propellers! sorry, but you knew somebody would go there

Ignoring the 3 laws of thermodynamics you can’t win you can't break even you can't stop playing

Ok, maybe not literal lighter-than-air aircraft, but some sort of hybrid. Batteries are kind of famous for producing gobs of waste heat: why not use that to produce some amount of buoyancy, so that the electric motors do not have to work as hard to produce lift.

Ethanol, from any source ("bio-" is kind of redundant), is far from carbon neutral and has issues of its own. Methanol is a little cleaner, but lower energy density and fraught in other ways.

Lighter-than-air air travel? I mean, it really could make sense for high-tech zeppelins. It would take a day or two to cross the country, but the surface infrastructure would not be compromised, airship landing fields would be more compact, and it would be harder for terrorists to do bad stuff...

We don’t need no immigration We don’t need no brown inflow No dark mestizos or their children Hey, generals, keep them all at bay All in all, it was all just tricks for the Wall

Come on, the proper quote is 3 words shorter: "… like his passengers". The ambiguity about the means of conveyance makes it much more evocative.

Well, he might have actually known how to swim, but he was, after all, wearing waders. That makes swimming rather a challenge.
