Why the Pope’s embrace of science matters


On June 18, Pope Francis issued the encyclical Laudato Si: On care for our common home. The letter has been widely praised for supporting the science on climate change. But it goes much further than many expected in documenting the phenomenal changes that our planet is undergoing, beyond climate. And the story of how the Pope has integrated science and religion (not always the easiest of companions, let’s face it) indicates, to me at least, a profound shift in world view.

The Pontifical Academy of Sciences has been bringing together climate scientists, economists and scholars pretty much since Francis’ papacy began in March 2013. My colleagues, professors Paul Crutzen, Veerabhadran Ramanathan and John Schellnhuber, have been part of a new level of dialogue between Earth system scientists and the Vatican. In April of this year, I attended a one-day scientific workshop on the moral dimensions of climate change and sustainable humanity.

What teens really want to know about sex


Remember how weird it was to ask questions about sex as a teenager? High school teacher Al Vernacchio answers his students’ questions about everything from DIY birth control to how to tell when a guy really likes you, in an excerpt from his new book.

On the first day of my Sexuality and Society class, I don’t pass around anatomy drawings. I don’t hand out pamphlets about safer sex, although those are stacked on a table near the door. Instead, the first thing I do is establish ground rules. People should speak for themselves, laughter is OK, we won’t ask “personal history” questions, and we’ll work to create a community of peers who care about and respect one another. Only then can we get to work.

I’m all about context. Talking about sexuality, intimacy, relationships, and pleasure can’t be done in a vacuum.

In the back corner of my classroom is an…

Una puta mierda


alumNo es un alumno más. Este es el segundo año que le he dado clase y en estos dos cursos no ha faltado ni un solo día. Participa en todas las actividades programadas en el aula con un interés que pocas veces he visto en mis más de quince años de experiencia docente. Pregunta, discute, debate… pero siempre desde el respeto hacia el profesor y hacia sus compañeros.

4 reasons why talented women don’t thrive in tech


We’ve all heard about the gender gap in tech. Women simply aren’t thriving in one of the most promising fields in the United States — and not for lack of talent. And here’s the truth: It’s not solely a problem for women. It’s a problem for men, too. In just five years, there will be a million unfilled computer science–related jobs in the United States, which according to our calculations could amount to a $500 billion opportunity cost. Tech companies are producing jobs three times faster than the U.S. is producing computer scientists. There are incredible opportunities here. We need women to help fill these jobs, and we need them now.

The reasons why women and people of color are not pursuing computer science jobs are complicated. I’ve thought a lot about this over the past 16 months, as I’ve directed my documentary on the subject, Code: Debugging the Gender Gap

Los Católicos Romanos son mas Protestantes de lo que se imaginan


Me parece justo, necesario y oportuno redactar este articulo, que siempre cuando lo menciono en mis predicas o charlas parece sacar chispas a mas de uno. Pero hay una realidad, que para el Catolicismo Romano siga sobreviviendo necesita aplicar principios de la Reforma Protestante en sus Parroquias como en el Vaticano.

Subversion and Mercurial

Having  used both Subversion and Mercurial, I think the best starting points so you can get your own conclusions about them are these posts:

Subversion: [Setting up and running Subversion and Tortoise SVN with Visual Studio and .NET][1]

Mercurial: [Hg Init: a Mercurial tutorial][2]

In short, Mercurial is a distributed version control system, while Subversion is a centralized one.

On Subversion, you “commit” and “update” directly to/from the central and unique repository.

On Mercurial, you “commit” and “update” to your local personal repository. Once you’re sure your code is ready, you can “push” your changes to the central repository. To get other people changes, you have to “pull” from the central repository.
