Comment It can be solved - the solution is Hydrogen (Score 1) 72

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) 72

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) 72

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 1) 47

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:Useless for any occasion (Score 1) 346

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...

Comment Yes I do have an idea (Score 1) 346

You have NO IDEA how effective the finger scanner will be.

Because it's an added layer on top of a system that already sometimes fail (guns jam or sometimes safeties will not release), and furthermore it's an electric system requiring power to function - I can guarantee it will increase the failure rate in successful access to gun for self defense.

To put that in real world terms, lets go for a very low figure and say the increase in failures means there are twenty more women raped in a year. Why would you be for that? Doesn't sound like a good tradeoff to me.

In reality of course the increase in allowed raped would be much higher because it would be mostly females purchasing a "smart" gun, misled by people like yourself into thinking they are better in some way... it's kind of like you are just one step removed from raping them.

Comment Re:You use an AR-15 to protect your home (Score 1) 346

You and your AR-15 don't stand a chance against a modern mechanized army

As is proved so very well by ISIS and the complete destruction they have undergone...

Oh wait, they have a whole state of their own built on AK-47's (same difference) and theft.

If freedom's your bag start trying to figure out the wealth inequality problem. Money is freedom.

Right, because the value of "money" is not arbitrarily determined by the state and can not be pulled or disabled remotely at any time... Oh wait again.

In a conflict free world you would be right that money is power. But money the way you are thinking about it is a dangerously thin illusion of power.

Comment Useless for any occasion (Score 1) 346

Seems like it would be useful in an environment like a gun range where you aren't relying on it for safety.

A) as another poster noted, the whole reason you go to a gun range is to get more better at shooting the guns you have, so that if you need to (or want to) use them for real later - either quickly like self defense, or more methodically like hunting - you know how well you can aim with them, what realistic distances are, how much kick to absorb or correct for...

B) Which leads us to a fingerprint scanner being a disaster in a crisis situation like a home invasion, you don't have the time for that nor want to rely that a gun you might have not touched for a while still has power enough to enable the fingerprint scanner. Similarily if you go hunting, it would REALLY REALLY SUCK to travel for hours to find out your fingerprint friend has no power or just decides that environmental conditions mean your fingers are now invalid.

So said fingerprint scanner gun would never be a gun you would use in real life, making it pointless to shoot at the range,

Comment Seems pretty arrogant to assume "bugs" (Score 1) 206

But the things you listed aren't features of intelligence, they're bugs in our brains

Maybe they are the way an optimal system works, which is lots easier to believe than thinking they are some kind of "mistake" or de-emphization.

You remind me of guys whose first answer to seeing a complex system is always to refactor it...

Comment None of that makes sense (Score 1) 138

What, do you work for Samsung or something?

I guess we can assume you work for a company that makes external batteries since you are advocating that position...

1. Removable batteries have significant armor as they may spend time out of the device

Which means they have less battery and your phone will not last as long.

This armor would have protected the battery from localized temperature spikes.

From EXTERNAL temperature spikes, which you (and Samsung) have no idea if they are the source of the issue.

2. Removable batteries contain internal thermal and current protection, and often fusible links.

I think it's funny you imagine internal batteries do not have those features also.

The connectors cannot be tightly spaced because they must allow for movement.

Why would it matter if the connectors are close? It doesn't seem to matter to ANY OTHER PHONE MAKER.

Even if a battery short were somehow possible, the battery would have protected itself rather than igniting.

And you know that how again???

3. If there are problems with the battery, it can be returned and exchanged without the device.

Which may or may not be TOTALLY IRRELEVANT to the issues that Samsung has, the only known case where lots of people had to turn back in devices.

4. If it turns out the device is defective, it can be easily shipped without the battery and the battery saved or recycled separately.

SO stupid and pointless I can't even.

Comment In reality, hours... (Score 3, Interesting) 490

Five minutes to put in a card.

One hour plus to decide which card to buy that will work best with your system and/or local network (and by one hour, I really mean "an entire evening of reading technical reviews" if I'm being realistic).

One to five hours to fix stupid driver issues that arise because of said new card that took only five minutes to put in... for every major OS update.

Sorry man but you can't get that kind of lie past me, I used to upgrade Windows systems also. I got off that damn train so that I could live life, and spend time doing things WITH computers instead of TO them.

And as for the $500 logic board upgrade - that's after three years, otherwise it's free. Or they might just give you a new system instead.

You keep popping cards in there and rooting through your OS though like some kind of animal, if you enjoy it more power to you.

Comment Whole point of Mac Pro is better heat dissipation (Score 1) 490

As the other responder noted, the Mac Pro specifically does not use hard drives, it's all SSD (as are most other modern macs, with the exception of some iMac models).

But even if it did have hard drives, the Mac Pro design is the way it is to ditch as much heat as possible. It's a vastly better design than a box with a few holes and a fan.
