Comment It's worse than that (Score 1) 177

It's not that women are not choosing to go into computer fields. It's that they are being SCARED off by being told how horrible it is for women - even though I cannot think of any field in which women are generally treated better, and respected for knowledge.

I agree we should let people choose what interest them but women currently are being painted a very false picture of what being in the computer industry is like, leading to misinformed choice.

Comment Re:"Tacit approval"? My nose! (Score 1) 185

Again your interpretation is contradicted by the first sentence of your source!

Read that again. Arranged the donation in 2014, this was started in 2013. I know, it's so out there...especially in context. Also re-read the first source, I'll give you the benefit of the doubt where you missed the important part.

Comment Re:Why does the ESA have a worse record of landing (Score 1) 93

I appreciate the explanation, but isn't it more that the new system was added in rush (to replace the old ones) as opposed to it being the first time used? It seems like the NASA successes were first time uses of those landing systems also, from what I remember.

Also, I really don't understand how IP applies since these are not products for commercial sale nor used for commercial purposes. I don't see where NASA could even bring a suit.

Comment Not Practical (Score 1) 158

You can't just handwave away the massive cost of proving a charger per parking space, nor even the cost of an outlet per parking space along with the electrical lines buried capable of having every single parking space drawing enough current to charge...

Even if that were practical what exactly do you imagine will happen to someone's personal charging cables or equipment left unattended overnight. Thieves are taking copper pipe out of buildings with the water still on...

Comment 3D first, self-flying much easier (Score 1) 75

Great. Let me know when it's bulletproof in a 2D environment and I'll consider the 3D version.

That's actually backwards. Solving for the 3D case is vastly simpler, because while in the air you have very few obstacles to content with, you basically just have to be sure you can react to other planes, and have programmed in the coordinates of no-fly zones - otherwise travel is just a straight line. There are already drones that can find their way back home if the control signal is lost, and almost drones that can fly around tree branches without hitting them...

For takeoff landing you can simply dictate that a solid volume of sufficient space must be below or above you to land/takeoff.

Comment It can be solved - the solution is Hydrogen (Score 1) 158

I've noticed that also in the past when traveling and staying with friends in Europe.

That's why I still think the future for most electric cars will end up being hydrogen, not battery power - though with advancements like these battery may be a higher percentage, especially if you could go somewhere just one day a week to spend a half hour charging.

Comment Normal is not what you think (Score 1) 158

Long charging times are for most people only a problem on vacation. Normally people commute much shorter distances than the maximum modern electric cars can drive and can charge their cars at night.

I love how you say "normally" when the vast number of people who have cars live in apartments where it may not be "normal" to have a plug anywhere near the car at night.

Is your goal to have electric cars for only the elite? Or for EVERYONE? If electric cars are to break out of a tiny niche for the rich they have to work for people who do not own homes.

Comment That would be the real game changer (Score 1) 158

Non-electric cars are simply more practical for most people not just because of range, but also charging time. Even Tesla Supercharger stations take way too long for most people to tolerate.

But if you have 1000 miles of range, suddenly it's much more practical to live with a very long charging time because you can wait a day or two to find a good charging solution - plus it would mean you could get somewhere faster than with a gas vehicle since you wouldn't have to stop on a long trip to fill up.

We'll see if the tech actually materializes in real life, but I really hope it does.

Comment Why does the ESA have a worse record of landing? (Score 2) 93

First of all, I don't see much mention that they still have a new satellite in orbit around Mars so the mission is at least partly successful.

But with a string of failures to land on Mars from the ESA, and a string of successes from NASA you have to start to wonder - what is it that is lacking in the ESA program that is not able to get landings right? Is it just different approaches to the problems of landing that are not panning out over a few attempts? Is it some kind of engineering process failure that they just are not accounting for some possibilities? I was wondering if anyone had any insight.

I wish the ESA the best of luck and really want to se them succeed, as the more craft studying mars the better (though they are all a handful of beans in comparison to the first human to land and study there).

Comment Re:Cost of loss? (Score 5, Insightful) 93

How much did all of this mission cost?

In the neighborhood of $1.3 billion.

Does anyone realize how much food that money could have provided to those in need ON THIS PLANET?!

$1.3B would buy in the timezone of 300 million big macs. Which would be enough for every poor FAMILY in the world to get a Big Mac. Hardly a significant impact on world hunger.

Note that if ALL the money ever spent on space were spent on food instead, we'd be worse off. The weather satellites alone paid for the entire world's space exploration budgets in better harvests as a result of better weather prediction....

Comment Re:fallacy (Score 4, Insightful) 164

No, not at all, because doing what you described is incorporating brand new data every year.

They kept adjusting the algorithm over and over until they got the right answer from 1980 onwards. The huge risk with that method is overfitting, and if you develop an algorithm this way, it's important to also show that you've managed to avoid overfitting.

You can do the same thing with stock market data: adjust it until you get nearly 90% correct returns on a test interval, then you will find that the next year, the model is completely wrong because of overfit. Even if you incorporate the next years data, you will still get incorrect results because the nature of the stock market is chaotic and also random.

Comment Re:Useless for any occasion (Score 1) 389

You mention hunting - is it really a quick draw sport where if the reader takes an extra few seconds to recognize you, it's a critical failure?

Yes depending on what you are hunting, sometimes you have only a moment, and you never walk with guns at the ready.

I don't even bother to read the rest of what you wrote, it's so absurd to argue with someone with zero understanding of the subject. It would be like trying to discuss the drawbacks of various design patterns with a toddler...
