La Hora del Planeta

I’m not sure if you remember, but a few years back (2007?) the city of Sydney turned off all non-essential lights for an hour to raise awareness for the need to fight climate change. That “La Hora del Planeta” has now spread around the globe, y, bien, today’s the day.

Earth Hour will take place at 8:30 a 9:30 pm your local time.

What can I do?

De nuevo, in Earth Hour you turn off all non-essential lights and other electronics. That means you shouldn’t go around and turn off all the streetlights you can find (that would lead to mass chaos.) En lugar, you should turn off:

Firefox 4 is out

It’s been about a year in coming (it was in beta for a full year), but Firefox 4 is finally out and can be downloaded at firefox.com. The open-source web browser’s latest version is a gigantic step forward from the 3.6 version (the old stable version from a year ago, which is pitifully outdated by now.)

What’s changed

  • Firefox 4 is about 3 times faster in page loading and JavaScript performance than 3.6. This means your favorite web apps and websites are – get ready for this – 3 times faster than before.

Microsoft helps kill spammers

Bien, not really kill, just bring down. Pero tiene el título suena bien.

En otras noticias, Microsoft por fin ha hecho algo bien mediante un descenso de Rustock, una red de bots que infectó millones de ordenadores y los llevó a enviar grandes cantidades de correo no deseado. Rustock fue uno de los (si no el) mayores redes de spam en el mundo.

Microsoft (and some feds) raided some hosting facilities in the US and took down the servers that instructed infected computers to send spam.

Laberinto

Como de costumbre, Me aburrí así que escribí un juego en JavaScript. Es un juego de rol llamado Laberinto (you can find it aquí) que sigue a un hombre que se pierde en una cueva. Usted tiene que recoger palos de destruir barriles, tablones para cruzar el agua, llaves para las puertas de colores, y más.

Esto es lo que se ve como Laberinto:

Playing Level 10 of Labyrinth
Igualdad de condiciones 10 del Laberinto

I know it’s horribly drawn, but I drew everything myself. I’m such a bad artist that it’s a miracle that the key even looked like a key. And that glowing yellow/orange/red thing is a lantern.

Internet Explorer 9 is out

Bien hecho, Proyecto de ley, por fin has hecho algo bien. Internet Explorer 9 is now out and can be downloaded from microsoft.com. Aquí está el truco: it only works on Windows Vista and 7.

Let me repeat that:

It only works in Vista and 7. It doesn’t work in XP.

Thoughts on the new browser

For one thing, it’s a lot better than Internet Explorer 8, although that isn’t saying much. To be honest, it’s actually decent; Internet Explorer can now compete with the other popular browsers like Firefox and Chrome.

Here’s what really matters:

Calculadora con motor JavaScript

I was bored (and my calculator was out of batteries), so I figured I’d take a crack at developing a web-based calculator. (You can find it at hathix.com/etc/calculator. Fundamentalmente, you can enter some commands (variable declarations or function calls) and the calculator will use JavaScript power to find the answer.

The neatest thing about the calculator is that it has some built-in functions (anything from finding a number’s square root to finding the LCM of two numbers to finding the solutions to a quadratic equation.)

Here are some commands you can enter into the calculator and what they do:

7-Cremallera: un camino libre para descomprimir archivos

Mis padres se acaba de descargar un archivo comprimido de la Internet (no estoy seguro de lo que era, Creo que un instalador o algo así.) Pero ese no es el punto, lo importante es que se necesita para descomprimirlo para poder acceder a los archivos dentro de. Ellos descargan WinZip, que le permite descomprimir archivos.

Todo está bueno, derecho? El único problema es que cuesta mucho. $30, de hecho. Eso no parece ser mucho, pero la regla general del pulgar con el software es:

Si sacó su tarjeta de crédito para descargar algo, probablemente le presté demasiada.
