Eating food contaminated with radioactive particles may be more perilous than thought—at least for insects. Butterfly larvae fed even slightly tainted leaves collected near the Fukushima Daiichi Nuclear Power Station were more likely to suffer physical abnormalities and low survival rates than those fed uncontaminated foliage, a new study finds. The research suggests that the environment in the Fukushima region, particularly in areas off-limits to humans because of safety concerns, will remain dangerous for wildlife for some time.

Here’s the scene: A problem has come up with one of your supply chain vendors, threatening to delay timely shipment of your product. At the same time, a potential opportunity appears that, with some exploration and investment, could lead to a new generation of products down the road. Which do you respond to first?

Get all the benefits of the latest Raspbian release without wiping your Raspberry Pi and starting from scratch by manually update it…

All you’ve got to do is follow these terminal commands and you’ll be up and running in, well, quite a while actually (it can takes ages, but you can leave it to it). The only caveat is that any new software that comes bundled with the new release wont be installed.

If you run a website that uses SSL, you can test your website using a small SHA-1 testing tool I built that will tell you what you need to do.

Even if you don't, I encourage you to read on. In the rest of this post, I'll cover how SSL and SHA-1 work together on the web, why it's as urgent as Google says it is, and what web browsers are doing.

Alien invasions usually involve extraterrestrials arriving at Earth to destroy, enslave, or eat humans. It’s always humans, too—I’ve never read a story where the aliens were bent on destroying all squirrels.

An informed guide to misconceptions of Agile.

I recently came across a rather misinformed document called the Anti-Agile Manifesto. Normally, I just ignore this sort of thing, but in this case, people I know who are in the exploratory phase of agile adoption were treating the document seriously. Because the thinking in this document, which is not uncommon, undermines the success of fledgling agile shops, it seemed worth discussing it.

What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs—including the brain. Many experiments have shown that after or during exercise, even very mild exertion, people perform better on tests of memory and attention. Walking on a regular basis also promotes new connections between brain cells, staves off the usual withering of brain tissue that comes with age, increases the volume of the hippocampus (a brain region crucial for memory), and elevates levels of molecules that both stimulate the growth of new neurons and transmit messages between them.

Perfection is unattainable: Learning English as a lingua franca (ELF) involves approaching the language as a tongue shared by non-native speakers around the world rather than as a lingo that must be mastered to native-speaker level. Letting go of the idea of speaking 'perfect English' could do wonders for Japanese students' confidence.

Over the past month at Lyft we’ve been working on porting our infrastructure code away from Puppet. We had some difficulty coming to agreement on whether we wanted to use SaltStack (Salt) or Ansible. We were already using Salt for AWS orchestration, but we were divided on whether Salt or Ansible would be better for configuration management. We decided to settle it the thorough way by implementing the port in both Salt and Ansible, comparing them over multiple criteria.
