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.

While a lot of work has been done on tone and intonation, there has been no large-scale test of whether lexical tone and intonation are, in fact, in competition diachronically. If a functional dependency between lexical tone and intonation exists, tone languages should be more likely than intonational languages to develop grammatical devices to encode utterance-level meaning such as particles, word affixes, and changes in word order. On the other hand, if an optimal division of the phonetic space between lexical tone and intonation is often reached cross-linguistically, tonal and intonational languages should exhibit grammatical devices for encoding utterance-level meanings at a similar frequency.

Enligt min mening är direktpension sedan länge är bättre än pensionsförsäkring. Och mina beräkningar ger resultatet att en direktpension ger bättre chans till avkastning om pengarna sätts direkt i exempelvis fonder och aktier än i en vanlig kapitalförsäkring på marknaden.

Här är svaren på de tre viktigaste frågorna när du ska pensionsspara i ett aktiebolag.
