In a world where our digital lives are tracked by democratic governments (Canada and the UK amongst them) we need to ensure that we can have private conversations online. Over at Digg they have collected a very easy to follow setup to get your protecting your privacy online in only an hour!

Keep Your Private Conversations Private

It’s rude enough for a stranger to even eavesdrop on your conversations in a place as public as a park. So opting to use messaging services with end-to-end encryption doesn’t make you some sort of criminal or tin foil hat-wearing nut. Whether you mind or not, there are organizations out there that are just scooping up every chat (Hello NSA!) you send out over the internet. No one is actively looking at them, or might ever look at them, but they’re listening so you might as well turn some music on or something.

It’s sort of like taping over your webcam or looking both ways before you cross the street — it’s such an easy and painless thing to do that it far outweighs the consequences of not doing that thing.

Think that because you have “nothing to hide” that you shouldn’t be concerned about being tracked? Or that it’s OK for the democratically elected governments to justify mass surveillance? Well, Edward Snowden has a nice and short counter argument:

Some might say “I don’t care if they violate my privacy; I’ve got nothing to hide.” Help them understand that they are misunderstanding the fundamental nature of human rights. Nobody needs to justify why they “need” a right: the burden of justification falls on the one seeking to infringe upon the right. But even if they did, you can’t give away the rights of others because they’re not useful to you. More simply, the majority cannot vote away the natural rights of the minority.

Simulations Help Predict How People Panic

- Adam Clare

Sadly there are still incidents of death that are a result of people panicking while evacuating spaces. For decades engineers have looked into ways to make buildings easy to evacuate and have made a lot of headway, unfortunately there are still times when their efforts are for not. Today the work into dealing with evacuating panicky people is being done by more than engineers; psychologist are using computer simulations to investigate new approaches to better building designs.

“One crucial aspect of crowd dynamics lies in the social interactions that take place between individuals,” say the authors. “These interactions create feedback loops and amplification effects and give rise to self-organized macroscopic patterns.”

The simulation was also run without the stressors and this led to some interesting differences. For instance, “In the absence of stress, participants tended to keep reasonably safe distances from their neighbors in order to avoid the collision penalty,” says the report. This means that there were almost zero body contacts. In the regular escape, the participants were prepared to sacrifice points in order to jostle their way to a faster exit.

Solar Sales Soaring Sixfold

- Adam Clare

Bloomberg is reporting that they anticipate a sixfold increase in star capacity thanks to the efficiency of a having a naturally-occuring ball of fire in our solar system. The sun is an abundant resource which shines its rays on us and now we have the industrial means to convert the sun’s rays into a powerful electric resource.

The growth of solar installations over the last decade of furthered their adoption in a positive feedback loop of success. As more places adopt solar the cheaper it becomes and the more incentive there is to make the whole system more efficient.

The “most attractive” markets for solar panels up to 2020 are Brazil, Chile, Israel, Jordan, Mexico, the Philippines, Russia, South Africa, Saudi Arabia, and Turkey, according to Irena. Global capacity could reach 1,760 to 2,500 gigawatts in 2030, compared with 227 gigawatts at the end of 2015, it said.

Smart grids, or power networks capable of handling and distributing electricity from different sources, and new types of storage technologies will encourage further use of solar power, Irena said.

As of 2015, the average cost of electricity from a utility-scale solar photovoltaic system was 13 cents per kilowatt hour. That’s more than coal and gas-fired plants that averaged 5 cents to 10 cents per kilowatt hour, according to Irena. The average cost of building a solar-powered electricity utility could fall to 79 cents per watt in 2025 from $1.80 per watt last year, it said. Coal-fired power generation costs are about $3 per watt while gas plants cost $1 to $1.30 per watt, according to Irena.

Email, Productivity, And How You Feel

- Adam Clare

Dealing with an endless stream of emails is challenge in any office environment – even just socially it can be rather taxing. The solution to email always seems to be just around the corner with a new startup from Silicon Valley appearing every year to “save” us from email. Here’s an idea it’s not that the problem is email itself rather it’s how we think about email.

Be free from the chains of email oppression by approaching email as something actionable rather than something to be organized. It’ll make you feel better rather than feeling pushed around by other people’s desires via email.

And that is the one way that email, in the sense of the tools and programs we use to process it, is at fault: technology has made it easier and easier to ask people to do more and more things, without giving us better tools or training to deal with the increasingly huge array of demands on our time. It’s easier than ever to say “hey could you do this for me” and harder than ever to just say “no, too busy”.
…
Decide you are not going to do those tasks, and simply delete them. Sometimes, a task’s entire life-cycle is to be created from an email, exist for ten minutes, and then have you come back to look at it and then delete it. This might feel pointless, but in going through that process, you are learning something extremely valuable: you are learning what sorts of things are not actually important enough to do you do.

What’s That? Use Your Phone to Identify Plants

- Adam Clare

Pl@ntNet is an app that can identify plants using the camera on your mobile. Presently, it’s limited primarily to Western Europe (since it was in France),Indian Ocean, and parts of South America. The technology behind it can be used to extend it elsewhere and let’s hope it gets more global support.

“What makes the project unique and innovative is that it is based on data collected through a large and dynamic social network that regularly collects field data, that shares this data, meaning that this knowledge is constantly updated which also allows the use of a certain number of visual patterns expressed by plants”.
