A direct drive 5 KWh (sic) electric motor ... flight time would be 1.5 to 2 hours. ... A full charge will cost you around 60 cents depending on where your power comes from.

If the energy were from wind or solar, the energy would cost around $1/kWh * 5kW * 2hrs = $1/kWh * 10kWh = $10. If that can last 140 miles, that works out to 7 cents per mile, or $5 per flight-hour.

The top end battery pack costs 8,500 $. So that is 1000 cycles = 1500 flying hours at a cost of 6.2 $ per hour! (cost of battery replacement divided by flying hours plus 60 cents per charging cycle).

If flight time were 2 hours, the pack replacement cost would be $4.25/flighthour. With solar/wind electricity as $5/hr fuel, this would add up to $9.25/flighthour.

Edit: the website says the large battery pack only holds 5.6kwh. Perhaps with losses (charging, etc.), that would approach the above figure of 10kWh per flight.

"Content you have requested is for mature audience only and requires age verification."

Can anyone try to explain why this picture was "mature"?
Although the article is satire, it does show the decision making process each candidate/staff took (although it might not have carried much weight, and may not actually affect the way they govern) when they were faced with the task of "I need a campaign website."
"If you have a bunch of money in stocks and savings, and no dependents, and you are going to die tomorrow, then it's rational to cash that all out and spend it in the most pleasurable way you can. (Or, if possible, spend it on figuring out a way out of my 24-hour countdown predicament!)"

That isn't any more rational than assuming that you're going to die tomorrow or live forever. Those are simply choices, rational or not.

Life is a part of death, death is a part of life. Breathing in means breathing out. Eating food means taking a dump. Being born means growing old. Imagining that you're going to die tomorrow isn't meant to make your life more special. It is used to invoke fear of death which in turns focuses you on the here-and-now (usually by triggering andrenaline). If you can become present in the moment without invoking fear of death, then by all means do so. Presence of mind lets you act powerfully; even mindless people react to someone with a powerful presence (>cough<Steve Jobs>cough<). It is worth cultivating and learning how to trigger at-will.

It is not "silly".

What's new is where a lot of independent programmers are.

What's necessary is for something very practical to require scheme. Ruby would still be a hobbyists language if Rails didn't come along. Perhaps arc could help here in the future but even the scheme community isn't totally amped on arc and therefore not rallying behind it.

Erlang seems better suited to be the next big lang than scheme. It has already found it's way into some of the big names like facebook and amazon, demonstrating practical importance, while solving problems that are still hard in other languages. cough concurrency...

People procrastinate for the same reason we stay up later than we should, and stay in bed even when there's no point in sleeping more. It's aversion to change. Everyone has this trait to some extent.

Although I have not used AdRocket, a friend talked to me about it and I would imagine that it would primarily be good for companies which offer a wide range of commercial products, or auction houses. Because of the variety, sharing this data and finding matches would more easily allow personal profiles to be built. As a consumer my favorite experiences with advertisements are the 'you may also like...' or 'find similar items...' services. This is not an easy task by any means, but if they do this successfully and possibly also allow consumers to use AdRocket to be used as a search or recommendation engine then they may really be on to something!

When I used to hang out in the workstation room at grad school, around midnight, I'd see guys feverishly trying to complete their beginning programming assignments. Invariably, some poor schmo was stuck trying to figure out where they went wrong with a doubly linked list implementation in C. They'd sit transfixed, staring at their code concocting all sorts of wild theories. I'd go up to them and tell them they should really try GDB. They'd always declare that they didn't have the time to learn it. Then at about 3:00 in the morning, they'd be desperate enough to try it. Most of the time, we'd find their bug within a few minutes.
If in neutral waters this could save them from troubles with jurisdiction and differences in the legislation between EU, USA, China, Russia etc.

Just to be clear, the phrase "productivity pr0n" is used in the headline not because it's a direct quotation, but because it succintly describes a lot of what Mann is eliminating.
Judging by the information on the Electraflyer website, much of the information at the blog seems to be wrong. The $18,385.00 price is not for the pictured Electraflyer C explerimental plane, but for this open-air frame tricycle with fabric wing:

http://www.electraflyer.com/tech.html

It is that tricycle that weighs only 247 lbs, not the experimental plane (the Electraflyer C), which is based on an "all metal Moni motor glider".

http://www.electraflyer.com/electraflyerc.html

The Moni was first introduced at the 1981 Oshkosh Convention. It was designed by John Monnett and sold as a complete kit including the engine and instruments. ... Approximately 380 kits were sold between 1982 and 1986. It is unknown how many Moni's have been completed and are currently flying.

The manufacturer of this neat little airplane, Monnett Experimental Aircraft, later INAV Inc., went out of business in 1986.

Stepping through in Smalltalk debuggers is (usually) easy and delightful. I had one student in a Smalltalk class (he was a quant, heavy math dude) declare the VisualWorks Smalltalk debugger came from God!

The debugger is so responsive, I routinely have 2 or 3 debugging sessions open, and write code in one of them. I'll write some exploratory code, evaluate it in the current stack context, examine the results, then dismiss it after copying the code back into the original debugger context and modifying it into an actual method. Sometimes, people will put a snippet of code in a comment and say, "debug this!" which is often informative and as easy to do as following a hyperlink. There's never a wait for a compile. It's not perfect -- you can get into trouble trying to debug parts of the system used by the debugger itself -- but for typical application programming, it's a joy! Oh, and with Smalltalk Server Pages, you can debug and step through in a completely natural way the rendering of a web page! (Yes, you'll see that HTML element there, then where you step into the message send for the dynamic HTML generation.)

Depends very much on who you're "marketing" to.

I.e., two of the most valuable "markets" are the primary attendees of e.g. DEMO... investors and press. The next tier can also be a boon: partners.

Another facet that's typically overlooked is the value in really getting clear on what you're delivering. Trying to get a powerful message about what you're doing into a 6 minute presentation in front of an audience of heavy-hitters is worth a lot. It was truly amazing to see so many aimless, jam-packed, and generally crappy presentations right up against so many really fantastic presentations.

Here is a flight report from a Moni motorglider, similar to the one erroneously pictured at dancewithshadows.com:

http://edhlund.com/PIREP01.htm

On my seventh flight I was ready for some mild aerobatics. I entered a left barrel roll at 4000 ft. and, 3/4 complete, experienced airframe vibration, loss of elevator control and nose pitchdown. I closed the throttle and held full back elevator but the pitch attitude, airspeed and vibration level all continued to increase until I was at a nearly 90 degree nosedown attitude and the airframe sounded like I was inside a garbage can being assaulted by baseball bats. About this time there was a tremendous "crack" and the airplane dissapeared from around me. I was tumbling through the air losing conciousness, but still strapped in my seat. Because of the violent motion I was unable to release the lap belt. The last thing I remember before losing conciousness was reaching for my parachute D-ring while saying goodbye to the world.

Miraculously, I regained conciousness on the ground, where I slowly realized that I was still strapped to the rear of the airframe, which had joined me in a fully unconcious parachute descent to a sitting landing in a nice plowed field. Another complete story follows where I got the seat belt released, only to be parachute dragged in a 20 knot wind with one arm and a dislocated shoulder entangled in the shroud lines, before finally shedding the chute. There were lots of broken bones and aches and pains. The NTSB investigation revealed that the starboard wing skin had debonded. The skin had departed outward, broken the spar and broken the aircraft in half at the spar box.

After some healing, and doing some research, I found that experts had been advising Monnett against this bonding method. He subsequently mandated a riveted wing, but didn't describe why as eloquently as I could have. Your editor, Carlos Emmons, and I then stripped the bonded skin from his wings (he wasn't flying yet) so easily it couldn't be believed. A little loosening with a knife at the trailing edge to get a finger hold, and a single jerk had the whole skin in our hands! We had bonded both aircraft and followed the book. ...

You do not have a certificated aircraft. The designer probably had no engineering skills, expertise or resources.

No, he didn't tell a lie. Religion is silly.

You don't have to "know" something is false to know if it's silly. Do I have a singing purple leprechaun on my desk? Well, think before you answer, Skepticism-Is-As-Bad-As-Faith; after all, you don't know whether or not I do!

So take a step back from your false equivalency and use the same common sense on this that you use every day in every other aspect of your life. If someone comes up to you with supernatural claims, every ounce of common sense and experience you possess should tell you that this person is probably saying something silly. And you shouldn't change your mind unless they actually manage to produce the kind of evidence that would change your mind if you were, say, sitting on a jury and contemplating a far-fetched alibi.

Excellent, thanks for the entertaining link.
Erlang is useful for writing concurrent, high availability systems. If you're writing a simple script to grep a directory and delete a few files or something, a scripting language like Python is fine. If you're writing a basic blog even, I'd say a scripting language like Python is the way to go.

But if you're writing a service like a database where there must be a lot of concurrent connections, Erlang has the feel of a high-level scripting languages, while being a compiled byte-code language.

Also, since Erlang processes are so lightweight and can run across multiple cores, it scales nicely with new CPUs coming out. So, usually without changing any of your code, as 4, 8, 16 core CPUs come out, your Erlang script should theoretically run 4x, 8x, and 16x faster, respectively.

Right. It's kinda ridiculous to see people on the east coast basically vomit a steaming pile about west coast events they only vaguely understand.

And besides, the reason so many startups go out to California is a larger tech talent pool. California has a lot of universities with excellent tech programs, very favorable laws and protections for tech workers, and very reasonable taxes for tech workers.

Incorporate wherever you want, your employees are going to look at the legal issues with working wherever you are. If your office is in a state that honors no-compete clauses, many people simply will not work there no matter how much money you offer them. Likewise, we've all got to pay our own private income taxes, and I'm not a big fan of New York's local taxes when your income rises above a certain level.

As far as I can tell, a few notable east coast bloggers are trying to spearhead a movement to call the East the new West for tech, and by and large it's failing because the reality is that despite the overhype and stiff competition, your engineers know they've still got a better shot in the Valley and surrounding areas than basically anywhere else in the country.

"Grandma went to heaven" is a statement of fact about a very specific matter that is either true or false.

The person uttering it has not seen, heard, smelled, or touched a single piece of evidence to verify this supposed fact.

Indeed, they're saying it either because they're sincerely repeating a myth they've heard since they were credulous children, because they want to mollify a grieving child's anguish, or both.

If you make a claim about the physical location of a human being, yet you have absolutely no evidence to bolster your claim, then you're making a claim that is not falsifiable and should be considered false.

"...believing in God is seen as the logical equivalent to believing in Santa Claus and the Easter Bunny. If you think I am totally deluded because of my beliefs, I would ask that you at least show respect for the fact that I am devoted to them and value them sincerely."

Do you not see the irony here? Would you be making this heartfelt plea for us to respect your beliefs if you did believe in Santa Claus or the Easter Bunny?

Of course not -- because a belief doesn't deserve "respect", no matter sincerely its followers may value it. A belief deserves either support or skepticism.

The adherents of every belief, however, deserve respect. As do you. Part of that respect involves an honest description of how unlikely your beliefs are to be grounded in truth.
