CodeAcademy is a website where you can learn to code JavaScript for free, in your own home environment, and be social about it. It was made by a couple of guys, Zach and Ryan, who were frustrated with the less effective ways of teaching how to develope codes.

First off, what is JavaScript? It's a scripting language usually implemented in websites to make the site experience more user friendly and enhanced. It's also used in desktop widgets, PDF's, etc. It popped up around '95 with Netscape and was influenced by the Java programming language. To this day, JavaScript is still one of the most popular programming languages on the web.

On Codeacademy, your lessons are personalized. You can use your own words for the lessons and chapters, and whenever you get past certain points, you earn badges! Being an avid FourSquarer, Steamer, GetGlue'er, and such- I find this a wonderful concept that really sucks people in. The lessons aren't written in geek-speak, so anyone can do it. Seriously, what classroom setting is going to say ""it's time to become a coding ninja!""?

When I was in college I took one coding class- Intro to Java. That's it. I have no coding ability whatsoever, but after taking a few lessons at Codeacademy, I know how to write a few simple Java Scripts. So if you are new to coding, this would be a great place to start. It'll get your foot in the door so you can have a headstart in more advanced material.

So, I'm impressed! Being a beginning coder, I'm not expecting to walk away from this site with the knowledge of a genius but after a few hours, I'll understand JavaScript a whole heck of a lot better.

Hacker Headlines

Watch out Ruby and Django, you may not be the only scripting languages in town to sport your own web server. This week Moriyoshi Koizumi of PHP.net posted an RFC for a built-in web server in the PHP binary. While this wouldn’t replace Apache as the web server of choice for major deployments, coders wanting to get a development environment up and running quickly would benefit from not having to write an HTTPD conf file.

Be careful what you download. 21 popular free apps in the market have been injected with root-kits and republished, AndroidPolice.com reports. “Guitar Solo Lite”, for example, was republished as “Super Guitar Solo” with the added functionality of secretly publishing your IMEI and userID, among other data, to a server in Fremont. Google has pulled the publisher from the marketplace and used its remote kill switch on the apps, but that doesn’t cover additional payloads which may have been downloaded from the 200,000-some zombie’d phones.

TorrentFreak reports that 70 percent of respondants to a Danish poll, say that they find piracy socially acceptable. 7 out of 10 said it’s acceptable, about 20 percent saying it’s completely acceptable, and 30 percent replied that it’s completely NOT acceptable. Although most that took the poll said piracy is ok, they mostly agreed that selling those downloaded goods for profit are completely not ok. I’m a little surprised to see how so many people think it’s alright.

Is Asus a fan of the Hak5 motherboard box case mods from weeks back? Possibly. The Taiwanese manufacturer showed off a concept shipping box that doubles as case for Mini-ATX motherboards. The box holds the motherboard and allows for additional components including hard disk and optical drives to be installed. I’ll go ahead and predict wall-mounted computer cases from Thermaltake next.

Thanks Lifehacker for the shoutout on our recent motherboard box case mod. Insert In-Soviet-Russia joke here.

Last year a 40-year-old computer specialist hacked into an advertising server and made a large plasma screen off a highway in Moscow play 20 minutes of porn (video). He faces up to 5 years in jail. This week the man plead guilty, to hacking into an advertising server and having a large plasma screen in Moscow to play 20 minutes of porn.

HakTip: Webcam motion detection round-up
7:04

I love those little tools that help out with everyday tasks. I have talked about motion detecting webcams in the past, but here are a few user picks:

Gary writes: If you want something sophisticated that runs in Linux try Zoneminder. Zoneminder is a professional quality, free, motion detection program for webcams and other cameras. It does everything Yawcam does plus more. In Ubuntu there are install instructions, and everything is in the repositories. Note, to prevent false triggers due to clouds passing the sun during daylight set up an exclusion zone. Another note, this program uses Mysql, Apache, Php and may be difficult to set up initially but is well worth the effort.

Ubuntu install guides and Zoneminder.com

Another viewer writes: Thought I’d let you know that Vitamin D is THE best webcam-software that there is. The ability to recognise motion between humans and animals, seriously!

Jason continues the internet enabled garage door opener project by writing an Android app.

The Android app has a simple interface allow access to a home Apache server, hitting a PHP script that interfaces with a USB Teensy over serial, activating relays connected to a remote.

Code available here.

Darren and Jason dive into making an internet enabled garage door opener by setting a home Apache server, hitting a PHP script that interfaces with a USB Teensy over serial, activating relays connected to a remote.

Teensy code :

void setup()
{
Serial.begin(9600); // USB is always 12 Mbit/sec
pinMode(17,OUTPUT); //Door
pinMode(18,OUTPUT); //Gate
}

void openDoor(int pin,int d){
digitalWrite(pin, HIGH);
delay(d);
//stop opening doors
digitalWrite(pin, LOW);
}


This week we’re breaking out the breadboard for an oldschool Hak5 mod — the Internet enabled garage door opener. Because when it comes to garage entry, what could be easier than writing an Android app to access a home Apache server, hitting a PHP script that interfaces with a USB Teensy over serial, activating relays connected to a remote. Duh.

PHP VirtualBox

What could possibly make the Hak5 wall-mounted virtual server better? A polished PHP front-end. And PHP VirtualBox delivers. It’s simply a matter of installing VirtualBox, and starting the vboxwebsrv (typically located in /usr/bin). Then install Apache and PHP (or your favorite LAMP stack) and toss phpvbox in your wwwroot. Edit the config.php and you’re all set!

Bandwidth Testing

You’re doing some major catching up on podcasts and downloading all the lastest episodes on your high speed connection when all of a sudden… It seems like the speed goes to a stand-still. What’s going on? Your 1 hour video podcast is going to take a day to download? Not cool! When this happens to me my first thought is… Bandwidth throttling by my ISP. And nothing ticks me off more than the ‘man’ taking advantage of that power. Can we figure out if this is happening? Possibly!

Google has a tool called MLab that measures your internet’s performance. Through this website, you can use different tests to monitor your performance… Or… your computer’s performance. Dirty. These can range from a regular speedtest with very detailed information, to a BitTorrent specific test. The other method is the Switzerland method by the Electronic Frontier Foundation. Switzerland detects any modified packets traveling over your internets, which sometimes can mean your ISP is throttling or blocking your downloads.

Go to Measurement Lab and click on test your internet connection. Choose the first one: the network diagnostic tool, and click on Start. This test will look for your internet connection speed and anything slowing it down. The test takes about 20 seconds. Once finished, click on Statistics to see a detailed guide of your network traffic and how it may be limited. Next, run the Glasnost test. This test will look for traffic shaping when you are using such things as flash video or BitTorrent. This test takes about 8 minutes to finish, and make sure any downloads you have going are paused. When this test is finished, it’ll tell you if it detects any kind of traffic shaping happening when using the selected program. The NPAD test will find and diagnose any problems in your end machine that have to do with network performance. Run this one and it will send and receive data, then show you any problems in red. Pathload2 is a bandwidth test that will find out what your available bandwidth is. For this test, you must download the EXE and run the test. The last test through mlabs is ShaperProbe- a traffic shaping test. It’ll tell you if your isp is traffic shaping when you upload, download, or both, and the max burst size before shaping begins. You also have to download the EXE for this test as well, click start, and wait for the test to finish. Next is the Switzerland test. Download the .tgz or .zip over at Sourceforge. Extract the files from the folder and read the INSTALL.txt for information on how to install it on your specific platform.

Well, according to these tests, I’m not being throttled… I just have a really bad internet connection out here in Missouri!

Ricky asks: “I just recently started using wordpress, and I am having alot of trouble trying to design a layout for it, I was wondering if you had any references or anything to help me learn how to do this, I understand HTML and only know a little of PHP. Any help would be greatly Appreciated.”

Darren recommends setting up a local LAMP stack, that is to say the web server, database and scripting language to support a WordPress install. The easiest way to get started is with either WAMP on Windows or XAMPP on just about any platform.

The WordPress install is dead simple.

Mostly I use PHP.net as my go to resource, but we’ll also be hooking you up with a copy of Mario Lurig’s PHP Reference: Beginner to Intermediate PHP5. Hope that helps.

The WordPress Codex is also an invaluable resource when you really get your hands dirty when theme code. Things like the loop and trim_excerpt are well detailed. Once you start learning the WordPress functions you’ll realize what a powerful content management platform it really is.

And finally we recommend WordPress.org/Support for their forums. If you know of a better forum for WordPress Theme Hacking please let us know!
