note-keeper, a script for your note taking needs

note-keeper is a small bash script to simplify the creation, editing and management of notes. It uses the text editor set up in the $EDITOR environment variable, but if that variable is empty it defaults to Vim in insert mode.

NASA open-sources its mini Mars rover, turns out to be a son of a (r)Pi

NASA‘s Jet Propulsion Laboratory (JPL) developed a mini version of the Mars Curiosity Rover, and open sourced the design and software used. The source is hosted at the agency’s Github account.

The project uses mostly consumer off-the-shelf parts. One of them is a Raspberry Pi, used as the “brain” of the rover.

From the Github repo:

JPL is always looking to inspire the next generation of scientists, engineers, and roboticists to help us explore and learn about our solar system (and beyond!). We release the plans for this rover as a way to try and give budding enthusiasts a fun robotics project that will help teach them and get them involved in robotics sooner and at a lower cost.

If you were looking for your next DIY project, look no more.

TESS is officially looking for exoplanets

Step aside, Kepler, TESS (Transiting Exoplanet Survey Satellite) is in town and ready to discover more exoplanets (planets outside of our solar system) and closer to “home”.

From Engadget:

TESS is a follow-up to Kepler, a spacecraft that has spent the last nine years searching for Earth-like exoplanets near Sun-like stars. Though it may be on its last legs, Kepler has already found 2,650 confirmed exoplanets and even more are expected to be discovered from the data it has collected. But Kepler was designed to focus on a small section of the sky and while it spotted many exoplanets, a lot of them were very far away from Earth. TESS, however, will eventually map about 85 percent of the sky and it will attempt to spot exoplanets a bit closer to Earth — which allow other telescopes to study them more thoroughly.

All I can say is: send alien nudes.

Fim-de-semana na Costa Oeste

Chegou ao fim aquele que foi o primeiro de dois fins-de-semana deste verão em que consigo ir passear para a praia. Ele foi passado na Costa Oeste, entre Peniche, Atouguia da Baleia, São Martinho do Porto e mais uns locais.

Estes dois dias foram uma ótima oportunidade para comer peixe grelhado, apanhar um bronze à camionista e ensinar a minha co-piloto a interpretar o mapa que aparece na aplicação Google Maps. A parte da interpretação do mapa é um trabalho em progresso e provavelmente nunca vai deixar de o ser, mas houve claras melhorias. 😉

Através do Booking.com, conseguimos alojamento a poucos minutos a pé da praia (menos de um minuto de carro) e a um preço realmente acessível. As ligações a diferentes localidades costeiras também eram porreiras, apesar do mau estado de algumas estradas.

No geral, foi uma experiência boa e a repetir. As praias da Costa Oeste têm água mais agradável que as da Figueira da Foz.
