Comment Flow Batteries (Score 4, Informative) 130

Had to look this one up! From the wikipedia:

A flow battery, or redox flow battery (after reduction–oxidation), is a type of rechargeable battery where rechargeability is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane.[1] Ion exchange (providing flow of electric current) occurs through the membrane while both liquids circulate in their own respective space.

... While it has technical advantages such as potentially separable liquid tanks and near unlimited longevity over most conventional rechargeables, current implementations are comparatively less powerful and require more sophisticated electronics.

On the negative side, flow batteries are rather complicated in comparison with standard batteries as they may require pumps, sensors, control units and secondary containment vessels. The energy densities vary considerably but are, in general, rather low compared to portable batteries, such as the Li-ion.

Comment LARP? (Score 2) 16

This might be the technology we need to bring LARPing out of the realm of 'extremely geeky'. Also, I bet the US military is going to want to get its hands on this one for training purposes. Or murder mystery theater when you're a participant in the actual spooky mansion? Or a Star Trek bridge simulator!

I'll be pretty excited when one of these comes to my city... just as long as the RealDoll people have to use a different room than everyone else.

Comment Re:Your phone as a lifestyle: NO. (Score 1) 137

But now instead of standing around awkwardly and occasionally trying to look like I care about the conversation, I can read Slashdot.

I can even hold up one finger in the middle of a long boring story, point at my phone and leave and no-one will think it's impolite. Even if it hasn't rung, and the battery is dead. Now THAT's progress.

It doesn't matter what browser you use if your ISP is spying on you. I just assume that nothing I do online is private, as I have assumed for the past 15 years.

(I didn't believe TOR was private either, until FBI agents told some prof to stop telling his students about it. So I guess it must work, at least some of the time.)

They are creating an environment for an algae bloom that are starting to cause problems everywhere.

And yet, they've been using shade balls since 2008 without incident. (See Ivanhoe reservoir.) You'd think that would be an easy problem to spot.

You have to admit, your post does sound a little, well, angry and extremist.

How about letting your users go there and see for themselves just how "extremist" it is?

Do... do we have some way of stopping them?

People don't get modded out of the community. They may be modded down, like here, but SN doesn't permaban people for expressing unpopular opinion like Slashdot does.

I think what he meant is that people get tired of being modded down all the time and leave.

What I can say is that a lot of the assertions you are making are bullshit, and you should leave it up to the few remaining non-corporate-sockpuppet users you have to decide for themselves.

Now you have to admit, this smells of extremism. The hostility. The defensiveness. The strong emotional statements that don't seem based in reality. OTOH, I'm almost certainly a corporate shill who can be ignored? Because Slashdot.

Comment Feminist vs egalitarian (Score 5, Insightful) 557

Why are you a feminist instead of a egalitarian?

Brianna: Egalitarianism is about equal rights for all people, but this is assuming that everyone starts in an equal situation, which is not the case.Feminism is advocating equal social, political, legal, and economic rights for women - and we are at a huge deficit with those rights.

I don't understand this answer; how is advocating for equal rights for women not egalitarian?

The value of a program is proportional to the weight of its output.
