It doesn’t matter whether the child is 4 or 14. In the moments before a meltdown it’s the face scrunching that gives it away. As body language goes it’s all out there, up front and very personal. A clear signal that your child is very sad and needs your help to cope with the rush of unbearable feelings. How do you help them out while keeping your cool—and perhaps even teach them a long term lesson about emotions?

Researchers have uncovered a flaw in the way that some servers handle the Diffie-Hellman key exchange, a bug that’s somewhat similar to the FREAK attack and threatens the security of many Web and mail servers. The bug affects all of the major browsers and any server that supports export-grade 512-bit Diffie-Hellman cryptography.

My goal in this guide is both to answer these questions, and, more importantly, provide an overall framework you can use to think about how to answer these questions.

One of the hardest parts of building for Android is making your app work well on all phones. While device fragmentation often brings forth concerns on design, the bigger struggle will be behind the scenes in managing memory, rendering smooth graphics, and maintaining battery life.

The German city of Hamburg has announced plans to become car-free within the next two decades. It is an ambitious idea, but city officials obviously feel that the personal motorcar does not fulfill a function that walking, biking and taking public transport cannot.

The goal of Hamburg’s project is to replace roads with a “gruenes netz” or a green network of interconnected open areas covering 40% of the city. According to the official website, parks, playgrounds, sports fields, allotments and cemeteries will be connected to form a network, which will allow people to navigate through the city without the use of cars.

Babies at high risk for becoming allergic to peanuts are much less likely to develop the allergy if they are regularly fed foods containing the legumes starting in their first year of life.

If you were to build a city from scratch, using current technology, what would it cost to live there? I think it would be nearly free if you did it right.

You may have heard that the NSA can decrypt SSH at least some of the time. If you have not, then read the latest batch of Snowden documents now. All of it. This post will still be here when you finish. My goal with this post here is to make NSA analysts sad.

TL;DR: Scan this post for fixed width fonts, these will be the config file snippets and commands you have to use.

Although there are a few different public-key encryption algorithms, the most popular — and fortunately, the easiest to understand — is the RSA algorithm, named after its three inventors Rivest, Shamir and Adelman. To apply the RSA algorithm, you must find three numbers e, d and n related such that ((m^e)^d) % n = m. Here, e and n comprise the public key and d is the private key. When one party wishes to send a message in confidence to the holder of the private key, he computes and transmits c = (m^e) % n. The recipient then recovers the original message m using m = (c^d) % n.

Microservices one of these ideas that are nice in practice, but all manner of complexity comes out when it meets reality. For this reason, I wanted to write this article to capture some of these and redress the balance.
