You mean all those bridges and highways that are operated by greedy capitalistic monolithic multinational corporations?

Basically, yes. Except that the corporation is called the US government, and it has changed its business purpose from providing liberty and the basic services necessary for the pursuit of happiness to the people, into being a corporate welfare institution.

Claiming that publicly funded and maintained infrastructure failures are caused by capitalism is a bit of a stretch.

Really? Look beyond the fassade, maybe. You don't see a problem with billions being spent on saving the financial industry, that were better needed to support the infrastructure?

We're tired of being told how horrible we all are by you authoritarian thugs.

For the record, here was the entirety of my post:

"Stories about women in tech always bring out the best in Slashdot readers."

And the AC takes this as "being told how horrible we all are by you authoritarian thugs". You just can't be nice to some people, I guess.

Comment Switching lights on and off really fast . . . (Score 1) 164

My Momma always told me not to play with the light switch . . . or "rev" the vacuum cleaner by switching it on and off to make it sound like a Honda.

You would think that if your kid was actually finding some entertainment in sweeping the living room that you would cut some slack to playing with the power switch to make a "cool" sound.

But I digress but only a little bit. The hydrocarbon and nuclear plants are backed up by brother hydrocarbon and nuclear plants. If one goes down and another takes its place, no one notices the difference. If wind cuts out, however, this miasma of partially burnt hydrocarbon fumes and radon gas permeates the land. The whole point of wind is to not burn hydrocarbons or split uranium atoms into dangerously radioactive elements, but it is too expensive to back up wind with excess wind capacity to prevent using those foul backup sources.

> In a pretty well sealed facility like this, the insects really don't have much place to live. There's no soil, so they can't live in the soil,

Not all pests require soil, some are quite happy on leaves/stems, or even in bare roots.

Just off the top of my head, thrips live in soil before they become adults and move up to the leaves. They have been observed to thrive on hydroponic crops just fine.

Of course, we already have the answer on this....they do a sanitary cleanout.

Shit, I know a guy who doesn't do that, and uses no pesticides. He manually inspects every leaf, every day, and manually kills any bugs he finds. Works great. Doesn't scale very well to crops where you can't call 1 room full of plants your full time job.

If you have no pest problems, and you are not using pesticides, I don't care how sealed your facilities are, you must not be keeping continuous crops for long periods.

and basically all paper (it's just cheaper for paper).

A lot of the paper pulp is coming from tropical palm plantations; they are much quicker to yield than temperate forests. Paper pulp demand is still causing deforestation in tropical areas, just not so much in the US.

How To Build With Delrin and a Laser Cutter 25

szczys writes: Laser cutters are awesome, but you have to bring your mechanical engineering A-game if you want to build resilient stuff using laser-cut parts. Joshua Vasquez has been building up his bag of tricks using Delrin and a laser cutter to build with techniques like press-fitting, threading, snap-fits, etc. that aren't possible or are non-ideal with the laser-cutting steadfasts of plywood and acrylic. Delrin (PDF) won't shatter like acrylic, and it has more give to it, so even the less precise entry-level lasers can cut joints that will have a snug fit.

As long as we're going to reinvent the wheel again, we might as well try making it round this time. - Mike Dennison
