What I tried to say was more or less that without regular exposure to the night skies, fewer and fewer people will be interested in ever looking. Just seeing the skies clear skies once or twice will give you a "wow!" experience. But it's only once that pretty surface is old and familiar to you that you start asking deeper questions about what you're seeing.

I think the same thing is happening in other fields. Naturalists, or green biologists, may be losing mind share to lab biology and to other fields - in part of course because there's more money in white biology, but also, I suspect, because fewer people are familiar with and interested in local biotopes, and don't realize there's a lot of interesting things going on.

tl:dr: you tend to never become interested in things you have no personal experience with or connection to. And as humans become more and more urban, then fields such as astronomy will gradually lose mindshare. Regrettable but probably unavoidable.

Of course, the majority of humans now live in urban areas, and see little or nothing of the night sky at all, whether northern or southern. Perhaps I'm taking this a step too far, but would it be possible that we'll see a continuing decline in interest and support for astronomy and space technology as more and more voters and influential people grow up and live their lives without ever really seeing the skies?

And no Happy Hacking Pro. That's my go-to keyboard for any stationary use.

I do like the feel of the new chicklet Lenovo Thinkpads as well; I don't know why many people don't like them. Whoever decided on the layout, though (PrtSc between right-alt and ctrl?!) should be sent to the unemployment line as fast as possible.

With older (PPC?) based Macs, to update the firmware you had to power off the machine, then turn it on by holding the power button until you got an extra beep or sound. This would physically un-write-protect the firmware EPROM so that it could be updated by open firmware.

In their quest to make everything as "user friendly" as possible, they took out this hardware security feature, allowing the update to just happen without any physical action.

Bad Apple, no donut.

Hotels will make you pay just to use an electrical outlet in a meeting room.

They charge for every little tiny thing, simply because business execs will just sign off on all of it and not care about a "paltry" $100 "outlet usage" fee.

Meanwhile, these fees can be big problems for smaller budget conventions, such as fandom cons. The artist alley at half the furry cons I've been to have a policy keeping artists from plugging in their stuff to charge because the con gets dinged hundreds of dollars in penalties by the hotel.

It truly is a non-customer-friendly business if you're not a big company flush with cash.

Great idea! Now we all only need to agree on which language to standardize on. I'm sure that worldwide discussion will be calm, focused and productive. Please post the results here in the thread once it's been decided.

I suggest Swedish. It's just about equally well known by almost everybody in the world, so nobody is starting out with an unfair advantage. I get a lifetime gig teaching Swedish to everybody. And you get umlauts! Win-win.

Oh, and by "suggest" I of course mean "absolutely demand or I will refuse any part of this scheme".

We have a load control transponder here which allows the power company to temporarily shut off the air conditioner and/or water heater, basically creating a "rolling blackout" of just those devices when demand for power exceeds supply.

The fact that they deploy such devices suggests utilities would be happy to shed some load, especially during the brightest time of day when solar works best and air conditioners are working hardest.

So what's the deal? They want us to use more power after all?

I pretty much agree. I'm an old-time Unix and Linux user, but Unity works pretty well for me. It mostly manages to get out of the way of my work - the single most important feature of any desktop - and things such as the single menu gives me vertical space for another line or two worth of visible code.

There are some real irritants. The window/app switcher has never gotten the distinction right (and I don't think it's possible), and the quick search misses things it should find. But these are smaller irritants on a desktop that does what it should do - be invisible unless I explicitly need any of it.

"we've got monkeys that have rapidly learned to control a robotic arm using only signals from a tiny cluster electrodes in their brain,"

"rapidly" and "control" are very much relative terms in this case. And note the "in their brain" - you need to implant an electrode array to get good, reliable signals. With monkeys you can do it to half a dozen animals and hope than one or two get a fully working implant. And the array has to be working for a few months or so. With a human patient you need to get it right every time, and the array has to be viable for a decade at the very least.

I can't get to the paper, but it doesn't actually say anywhere that the girls were uniformly better. All subjects improved their understanding of computation, but the girls as a group did significantly better.

Also, when you look at more interesting and original, less copy-pasty games, female developers and designers seem to be more common than in the industry overall.

How should one go about getting a job programming a large supercomputer?

Become a researcher in a field that makes use of lots of computing power, then specialize in the math modeling and simulation subfields. Surprisingly often it's quite easy to get time on a system if you apply as a post-doc or even a grad student. Becoming part of a research group that develops simulation tools for others to use can be an especially good way.

Or, get an advanced degree in numerical analysis or similar and get hired by a manufacturer or an organization that builds or runs supercomputers. On one hand that'd give you a much more permanent job, and you'd be mostly doing coding, not working on your research; on the other hand it's probably a lot harder to get.

But ultimately, why would you want this? They're not especially magical machines. Especially today, when they're usually Linux based, and the system developers do all they can to make it look and act like a regular Linux system.

If you want to experience what it's like, try this: Install a 4-5 year old version of Red Hat on a workstation. Install OpenMP and OpenMPI, and make sure all your code uses either or both. Install an oddball C/C++ compiler. Access your workstation only via SSH, not directly. And add a job queue system that will semi-randomly let your app run after anything from a few seconds to several hours.

I do that on the train every day already. I mostly read, play games or study language. I have occasionally done light developing too, but it's too short a time frame to get into it and really get anything done.

Lead acid batteries last longest when they are fully charged and kept that way, and discharged infrequently. This makes them excellent for use in standby power situations, where they are almost always topped up ready for the power to go out.

Li-Ion batteries last longest when they are actively used. Keeping a Li-Ion battery fully charged all the time is bad for its longevity; the battery structure breaks down faster at a high state of charge. This is why it is recommended to store Li-Ion batteries half-charged in a cold environment, and why cars like the Tesla Model S normally only charge up to 80% unless you require a "full-range charge" for a road trip. Not topping off to 100% extends battery life.

Maybe Facebook intends to keep the batteries at 80%, but it's hard to believe the economics are going to work in their favor.

Not to mention that lead-acid batteries are mostly water and non-combustible sulfuric acid. A Li-Ion battery fire is 50 times nastier than a lead-acid battery fire, and produces a hell of a lot more noxious gases.

The original twin towers DID use robotic window washers. They were built in 1971.

This problem has already been resolved, but they didn't design the new building in a way that robotic window washers could be implemented easily.

Oops.
