• Drones que luchan contra el cambio climático

    Hace poco hemos podido saber uno de los últimos usos de los drones que hacen lo que más nos gusta, poner su granito de arena contra el cambio climático. Os explicamos cómo y dónde se están utilizando.

    El uso de aeronaves no tripuladas que se está haciendo en Escocia para luchar contra el cambio climático nos ha entusiasmado. Y es que, recientemente, la Marine Scotland (agencia para asuntos marinos del gobierno escocés) ha publicado un estudio en el que se habla de que los drones pueden ayudar a paliar estos efectos en los ríos puesto que pueden ayudar a aportar información sobre dónde es el mejor sitio para plantar árboles.

    Pero, ¿qué significa elegir correctamente dónde plantar árboles para ayudar al cambio climático? Al contar con cámara termográfica, los drones pueden arrojar información sobre qué zonas de las riveras son más o menos calurosas y, así, elegir las más adecuadas para que los árboles crezcan y se desarrollen con garantías.

    La investigación, realizada gracias a la colaboración con la Universidad de Birmingham se desarrolló debido a la creciente preocupación ante la subida de temperatura generalizada de los ríos, lo que supone un grave peligro para algunas especies de peces que suelen vivir allí. Una de las mejores soluciones para bajar de nuevo la temperatura de los ríos es plantar vegetación cercana y, sabiendo que los drones pueden aportar información muy valiosa sobre este tema, están seleccionando las áreas concretas donde es más eficiente realizar esta labor de reforestación.

    En Dron Planet también ponemos nuestro granito de arena gracias a nuestra experiencia en el uso de drones con cámaras termográficas en proyectos relacionados con impacto en el cuidado y preservación de los recursos naturales. Además, hemos colaborado con la Universidad Politécnica de Valencia y el IVIA en un importante estudio sobre la optimización de riegos en cítricos utilizando sus drones equipados con cámaras termográficas.

    Hasta ahora, el desarrollo de estudios para conocer toda esta información que los drones están ofreciendo resultaban carísimos y muy lentos. Ahora, con la flexibilidad que sólo las aeronaves no tripuladas ofrecen, podemos luchar con más exactitud contra el cambio climático.

  • What’s the best VPN for Netflix?

    What’s the best VPN for Netflix?

    The internet may be global, but contracts often aren’t. That means you’ll often find a service streaming one lot of movies and TV shows to customers in one country and a different selection in another country. So what happens if you live in country X but want to access the stuff Netflix streams in country Y?

    The official answer is: you put up with it, because if Netflix doesn’t have the rights to stream a particular film or show to you then that’s just one of those things.

    However, the unofficial, it’s against the T&Cs, here be monsters proceed at your own risk answer is that you can get around the problem with a VPN.

    What is a VPN and how can it solve my Netflix problem?

    A VPN is a Virtual Private Network. It’s essentially a private tunnel between you and the site or service you’re accessing. Where things get interesting is that the tunnel can appear to be somewhere that it isn’t, so for example, you might be in the UK but you may appear to be connecting from the US. That’s good for evading censorship, and it turns out to be a pretty effective way of getting around geographical restrictions too.

    The reason it works for Netflix is because Netflix checks your IP address when you connect. If the IP address appears to be from the US, you’ll see US content. Simple.

    Will using a VPN get me kicked off Netflix?

    We don’t know of any cases where it’s actually happened, but your user agreement does say Netflix can restrict or terminate your account if you’re a very naughty streamer. However, Netflix can and does block various VPN services so that their users can’t bypass its geographic restrictions, and that means people using those services have suddenly found themselves unable to access the content they’d previously been able to access.

    How do I find a VPN that Netflix won’t block?

    The short answer is: you can’t. But you can find one that isn’t being blocked right now, and that doesn’t appear to be in Netflix’s sights. However, if you’re planning to sign up to a service purely to access Netflix then it might be wise not to sign up for a lifetime contract. Look for plans that don’t tie you in too long or that offer money-back guarantees if your chosen content suddenly becomes blocked.

    Is it hard to set up a VPN to watch Netflix?

    No. Most VPNs have their own dedicated apps that do everything for you, and some offer Chrome and Firefox plugins for effortless switching between VPN and normal browsing. All the good VPN services offer extensive how-to advice and good technical support too.

    What’s the best VPN for accessing Netflix?

    Different people will have different criteria, so for example some VPN users are really keen on services that don’t record any of their visits while others couldn’t care less. But for most of us the main issue is going to be speed. Without a good, reliable data speed streaming video – especially when it’s HD or better – quickly becomes swearing video as the quality takes a nosedive or stutters or stops altogether.

    Let’s look at some of the best candidates.


    From $6.67 per month (15 months up-front) to $9.99 per month (six months up-front).

    This would be our choice, not just because it’s exceptionally fast and solid – although it is – but because it covers all kinds of devices, including ones that can’t run VPN apps. That’s thanks to its MediaStreamer service, which provides DNS servers you can use to access Netflix from devices such as the Apple TV and games consoles as well as computers and mobile devices.


    Currently £2.72 per month (12 months up front) or £3.59 for Premium

    With apps for everything from Android to Blackphones, smart TVs and routers you should be able to get VyprVPN up and running on anything. It’s screamingly fast, not least because it can defeat ISP throttling, and there are no caps or fees to worry about. The free trial isn’t very long at just three days but that should be more than enough time to see if it does what you want it to do.


    $2.75 per month (36 months up-front) to $11.95 per month (billed monthly)

    NordVPN is particularly strong on protecting users’ privacy, and with support for six simultaneous device connections it’s well suited to busy households as well as censorship evaders. It works across Windows, Mac, iOS and Android as well as many other platforms (Raspberry Pi, routers etc) and with more than 4,000 servers worldwide it delivers speedy performance on a wide range of sites.
