Comment Pick your battles (Score 1) 1482

I think marriage is medieval property-transferring bullshit, but I really don't agree with anyone who thinks only straight couples should be allowed a screw-up.

However, the NSA is already spying on everyone, so I think you'd be stupid to write off the leading open-source browser for a machine with anything of importance on it. Choose some goddamn battles! I'm going to put basic privacy from abusive power higher on my list.

Comment Re:Agriculture for nerds. Stuff that matters. (Score 1) 116

But, being a closed loop system, any contaminants (such as nitrites, which is toxic to plants) produced are retained and tend to build up in the system. And ask anyone who keeps fish tanks how much work it is to keep a fish tank clean and balanced, even if you have a well established bacteria and plant system.

That's exactly why you should research this. A definitive aspect of aquaponics is that it includes a combination of nitrosomonas and nitrobacter bacteria which successfully convert ammonia and nitrites into nitrates which the plants consume. This means that the system takes a bit of time to ramp up to bring the fish, bacteria, and plants into balance, but once it is going, it is very low maintenance. There's a significant difference between this and the typical aquarium.

This kind of closed loop is definitely going to shake up agriculture in some form, not only because of its much smaller water consumption and higher density, but because the current state of agriculture is extremely oil-dependent for both its machinery and its fertilizer and pesticide production. Reducing that dependency is going to matter a great deal.

Comment Eric, look... (Score 1) 281

Everyone assumes similarity to themselves and their lives.

This is why rich people look at poor people and don't see how poor people live, but how absolutely lazy or irresponsible someone who grew up rich would have to be to wind up in those straits. They cannot assess the huge differences in opportunity, education, social connection, or positive expectation. They can't imagine seeing the world from a place of limited opportunity. Even the best-hearted of them can take a "poor vacation" and try to live the subsistence life, but growing up feeling you can't just walk away from that is one of the biggest aspects.

So what to Eric is expensive college tuition is ridiculously impossible for many others, especially considering that jobs aren't even available to that many college graduates anymore.

Higher education has been made the tool of class stratification. You're lucky to be born with the funds to have the odds on your side. And even if you give education all you've got, heaven help you if you're one of those who doesn't have health care coverage - recent changes being a bit late for those I know who tried to bootstrap when college was all they could afford.

The part of this story that the Slashdot audience could most easily get in on is aquaponics, which is producing huge yields in some cases and holds a lot of promise for the local food movement.

Aquaponics is a system you can use indoors or outdoors, on large or small scales. It is a closed loop wherein ponds full of fish, usually tilapia, have their water pumped through hydroponic grow beds full of food-growing plants. The all-important third ingredient is a bacteria which converts the ammonia of the fish waste into nitrates which nourish the plants. The water goes back to the fish clean and livable. Once the bacteria are established and in balance to keep this conversion going, the only investment this needs are the energy to keep the pumps going, stable temperatures, and fish food.

Because the density of available nutrients is quite high, the plants can be so too. Their roots mostly just need to grow straight down, so typical planting distances don't apply. The fish too get a cleaner environment, and the usual equations for how many fish per gallon of water can be exceeded. A stabilized, intelligently planted aquaponics system can grow a lot of food - this site (http://portablefarms.com/2013/part-one-sizing-your-aquaponics-system/) claims that 25 to 30 square feet of grow bed is enough to completely meet one adult's supply for table vegetables, and given that you keep the water quality high, the tilapia will make for very tasty protein too.

Because the water is in a closed loop system, very little of it is lost, and aquaponics is radically less demanding of water than traditional agriculture. Because you can grow this stuff indoors, chemical pesticides are neither needed nor desirable, for your sake and the fishes'.

Leafy green plants are the easiest to grow in this way, root vegetables some of the hardest. Tweaks on this system do keep expanding the options, however, like microgreens, wherein you harvest plants in the first two weeks after they've sprouted for a nutrient density four to forty times that of typical mature vegetables. So the question is, how could we make this the most easy thing to get started, so that people with little experience and limited time can skip the refrigerator and east straight from their greenhouse?

Done rightly, this system can shake up food supply as surely as 3D printers are going to shake up industry.

Actually there are a lot of ways that they could make this happen. Vertical farming, interplanting, and aquaponics all are producing very high yields. They can be more labor-intensive, but there's a lot of pay-off in having a local, resilient food system.

This place, for example, is growing a million pounds of food per year on two acres, even through the winter: http://growingpower.org/

Comment Re:Downsides to Austin (Score 2) 285

Sad to say, I know people who are working intimately with the water issues of Barton Springs and San Marcos, and what they tell me gives me great concern.

My advice: don't move into a house in or near Austin without rainwater catchment or a cistern. It'll be difficult just a few years down the road, and you'll be a drain on thinning resources. And for the love of god, don't expect to keep a standard issue green grass lawn through the summer. Native grasses and orchards, rainwater harvesting, even xeroscaping if you run out of ideas would all be better. People have got to respect that land more than the developers are presently.

Comment Downsides to Austin (Score 5, Insightful) 285

Austin is *not* ready to be a big city. Its infrastructure wasn't designed for it. Its traffic jams are some of the worst in the country, its aquifers are in serious trouble owing both to desertification and fracking around the Colorado River's headwaters, and much of its distinctive nature is being destroyed by new development. This is why you see signs reading, "Welcome to Austin! Don't move here."
