+ - Ask Slashdot: Non-coders, why aren't you contributing to open source? 4

Submitted by Jason Baker
Jason Baker (3502325) writes "Most everyone is using an open source tool somewhere in their workflow, but relatively few are contributing back their time to sustaining the projects they use. But these days, there are plenty of ways to contribute to an open source project without submitting code. Projects like OpenHatch will even help you match your skill set to a project in need. So what's holding you back? Time? Lack of interest? Difficulty getting started?"

+ - South Korea Bans Selfie-stick Sales

Submitted by Rambo Tribble
Rambo Tribble (1273454) writes "South Korea has instituted large fines for selling unregistered "selfie-sticks". The problem arises because many of the devices are using Bluetooth radio spectrum, and must be certified to do so legally. Expressing doubts that the regulations and stiff fines will influence sales, one official said of them, "It's not going to affect anything in any meaningful way, but it is nonetheless a telecommunication device subject to regulation, and that means we are obligated to crack down on uncertified ones,""

+ - Open source craft brewery shares more the recipes->

Submitted by Jason Hibbets
Jason Hibbets (2851661) writes "An open source craft brewery in Saint Paul, Minnesota is taking open source beyond sharing recipes. The goal for Tin Whiskers Brewing Company is to "engage and give back to the community by sharing an inside look at opening and operating a craft brewery." In this interview with co-founder George Kellerman, we learn a little more about why the trio of hobbyists who started the brewing company took the path to becoming professional brewers and why they decided to be more open. "The brewery community was extremely helpful and open, so being open ourselves seemed like a great way to honor that," Kellerman said."

huge amounts of deforestation (nine thousand acres worth),

Really?

It looks from the aerial photography you link to that they just cut tracks to each turbine.

Wind power is a joke regardless of how you look at it.

I look at it from price per unit, insulation from oscillating fuel prices, greenhouse emissions, and production of harmful waste.

It's not as funny as you seem to think.

> Remember, Hydrogen is really just a battery when you think about it, the power still has to come from somewhere else like coal (though ideally wind or solar). In most cases hydrogen is generated from natural gas, generating, you guessed it, carbon dioxide in the process.

The great thing about the Hydrogen economy, is you can increase the amount of renewable on the grid, and convert excess to hydrogen, when you have an excess, like in the middle of the day and the middle of the night.

You're reasoning in isolated abstractions: "biodiversity is good for humans"

That's pretty well accepted.

The argument you see in textbooks is that the interdepedence of ecological systems is such that at it is difficult to know what species are key to our own survival. so dropping biodiversity is like playing Russian Roulette. (Of course the rich will be able to supplement, but I mean key to our own cheap survival).

But more importantly to me is the intellectual resource. Each species comes with it's unique proteins and biological processes. Losing them without studying them is a permanent loss to our knowledge, and future study is more likely to have useful results than current study, as our understanding of the biochemistry allows fuller understanding and so utilization of the processes observed.

"tigers dying reduces biodiversity"

I linked to a paper with this (generalized) result: reduced genetic diversity withing species reduces biodiversity of other species in the ecosystem.

"ice sheets move slowly and allows migrations"

The species in current existence have survived the repeated glaciation cycle of the holocene. The current warming is more rapid, and in the wrong direction.

With that kind of superficial reasoning, you can "prove" anything in any complex problem by just picking out the right abstractions.

I think you're ignoring the proofs. If you think one of them is wrong, we can delve into it. But read the paper linking genetic diversity to biodiversity first.

Large predators are usually already evolutionary dead ends, candidates for natural extinction

That seems like an isolated abstraction. Do you have any science-based evidence of this claim?

Humans have killed off many apex predators in many environments over the past few millennia.

Can you give a few examples?

Generally, the main effect has been that human livestock and humans have become safer.

Do you have any science-based evidence of this claim? I think that it is wrong. When you remove an apex predator, biodiversity crashes.

Saloomy's claim was:

Historically speaking, were in the "colder than usual" range of the bell curve today, and thats with using ice cores to detect CO2 levels and temperature histories.

This is not true, using the data set [s]he mentions. We're much warmer than normal, according to the ice core record.

This is not, as you seem to have been suggesting that the Earth is less than a million years old, but that Ice Cores don't go back further than that.
