Comment: Millivolts "power"? (Score 1) 54

Unfortunately, I had to accept that Slashdot editors and submitters are not, typically, capable to distinguish between power (watt, W) and energy (watt hour, W h), but this is a... new low? Hell, I don't even know if it's new, with how things have been going, it is quite possible that there was a similarly disgraceful submission already.

Mentally insert image of double facepalm here.

The old gray beards today might say the same with IBM or Digital but once market forces correct a monopoly the company either whithers or adapts.

Did you sleep through the monopoly classes in Econ 101? There's no market force that corrects a monopoly. Microsoft still has a monopoly.

Under a free market people play nice or loose out.

Did you attend any Econ classes at all? That's not how markets works.

4. MS more liberal with pricing for non corporations. Google VS Community edition. It is pro and free!

Ugh. First hit is free. Site licensing has gone up radically. The kickbacks make it so.

5. MS is opening sourcing .NET and lots of frameworks

Uhhh, yeah... What's the plan here? Where's DotNet going? Abandonware...

6. Azure supports non win32 operating systems.

And? What's the strategy here? Follow Amazon? Uhh. Yeah...

7. MS is putting more effort in security and stabilizing and fixing bugs now that competition exists.

And? Fixing bugs is something for which we should be thankful? What's the transparency on that?

Browsers are competitive. Mobile operating systems competitive. Development environments are competitive. Clouds and virtual services for legacy win32 apps scare the crap out of them so soon if mega corps want to leave they can.

You mean all those free browsers are charging because there's a viable market? Microsoft is irrelevant in mobile.

Does Microsoft pay you much for this nonsense?

I'm not sure if I'm understanding your question, but it seems to me he'd be interested in stories and story telling.

  The key here is to help him explore what stories are powerful to the human mind. As a parent, Jung is your go-to guy for the reasons why stories have been retold for generations and should give you plenty of structure and direction for good material for your son to work with.

More simply, there are child friendly versions of Shakespeare, the stories told in Operas, and be careful getting a semi-authentic Brothers Grimm book. The original stories are a little graphic in places, but more powerful. There are also board games about story telling.

Hopefully, I haven't gone too far in the wrong direction. It just seems to me, good games always had good stories as structure.

"wave-particle duality is simply the quantum uncertainty principle" gets a "no shit" straight away from me, though I guess a rigorous proof of it is kind of news.

That's how science work.

That more about how math works. Physicists did not care that the calculus of infinitesimal was not rigorous; see especially the Dirac-Delta function. It gave them answers that agreed with experiment which for a Physicist is the best proof.

Right, but the sentence you are make fun of is talking about stabilizing the rocket as it is coming back into the atmosphere, ass first in a no longer particularly aerodynamic configuration as it is missing the whole second stage and payload section. Flight stability in the nose going first direction is much better than in the engine going first direction. They are not complaining how hard it is to go that last 10m to the landing; I agree with you that stability control at that point is pretty easy. You know the first attempt they made for power re-entry failed because the axial rotation of the booster caused fuel starvation to the engine due to centrifigal force. Full tanks and no rotation at launch save you from that worry.
And as for less mass being easier to stabilize - can you balance a pencil on your finger? How 'bout a broomstick?

And I don't mean the speed of light kind.

At 14 stories tall and traveling upwards of 1300 m/s (nearly 1 mi/s), stabilizing the Falcon 9 first stage for reentry is like trying to balance a rubber broomstick on your hand in the middle of a wind storm.

EXACTLY the same as takeoff. NO difference.

Same amount of fuel? No, so not the same moments of inertia. During launch the engine is pushing in the direction of travel, during re-entry no. During launch, the aerodynamics include that nice fairing on the nose, which should be a bit less chaotic than coming engine first down. The period of 1300 m/s travel that you quote and compare to launch is not during launch (0 m/s) - it is probably closer to the period of maximum dynamic load and clearly during super sonic travel. The reverse part of that travel, the period of maximal dynamic load during re-entry in a non-aerodynamic configuration is rather more difficult than getting off the pad.

The crash happened across platforms, though I have a limited view of it - I co-wrote Repton for Sirius Software, available on Apple II, C-64, and Atari 400/800. Sirius went out of business because 20th Century Fox failed a promised payment of $20mil. But I also worked for Infocom around '85 - and they were also crushed - maybe due to being text based.

Yes and no.

It's more related to the time period in which those neighborhoods were built, and how they were built. Grid street patterns were normal before WWII, along with smaller houses (Victorians, Craftsman bungalows, etc.). "Subdivisions" didn't become common until the postwar era, when sprawling ranch houses with two-car garages and big yards were popular.

Not coincidentally, those postwar subdivisions were also getting built at the same time as the civil rights movement: at the time, black people were "blockbusting" in those grid-street neighborhoods, while the white people were moving out to the curved/cul-de-sac subdivisons to get away from them. In fact, the restricted number of subdivision entrances/exits, along with the higher housing prices (enforced in the zoning code by minimum lot sizes, which forced lower-density development) were, in part, tools to keep out those perceived to be undesirable.

Very nice post, and very true.

I recommend watching an interesting, newly released documentary: Spanish Lake. It explains blockbusting very well, as well as the dynamic of white middle class families staying vs. moving out of neighborhoods.

My impression of most of the US (I visited three times, three different states) is that you're discouraged from walking - no walkways, no way to cross roads unless you're willing to walk half a mile to get to a crossing, etc. In Texas I felt like walking was practically a felony, and if you don't have a car you're subhuman.

Needless to say, when I left Texas and returned to my beloved Finland, I breathed a sigh of relief.
