HTML 5 in 5 minutes

HTML 5 is quite a hot topic at the moment, with good reason. HTML 5 is the first major update to HTML in over a decade. XHTML did teach us a lot of good disciplines which should be followed when developing with HTML 5. HTML 5 includes new APIs and features to reflect the modern browsing experience such as:

• video/audio – without plugins,
• geolocation – pin point and share your location,
• web sockets – threaded processing to reduce browser hangs,
• WebGL – like openGL and DirectX for the browser – game creation,
• BitMap (canvas)/vector (SVG) image creation -  on the fly graphics,
• Better page structure elements – Section, Article, Nav element – this is more for developers
• Backwards compatible and forgiving (XHTML 2 did not want to support this)

Hemi JavaScript Framework

Engine for Web Applications is a services framework. Hemi JavaScript Framework is the project name for Engine version 3.
Hemi may be used alongside most Web frameworks and libraries. Custom components can be loaded externally or easily built into the framework, deployed as separate script packages or as application components.
Key features include managing application interdependencies and bootstrapping (tasking), messaging, inter-object transactions, configuration, dynamic runtime components, templates, application containment, and monitoring. The application space service creates a containment and abstraction layer for associating script with HTML and XML content, and exposing declarative scripting with XML.

What’s new in JavaScript 1.8.5

What is ECMAScript 5?

ECMAScript is the official name of what we all call JavaScript. That doesn’t mean we’re wrong; it’s just that the name “JavaScript” is a trademark of Oracle; so Ecma International (originally the European Computer Manufacturers Association—hence ECMA) uses the term “ECMAScript” to refer to the standard of JavaScript. The latest version of this standard is the 5th edition, and it was approved just over a year ago (on December 3, 2009). It encompasses a huge range of great additions, and several of those are starting to show up in browsers. The implementations of ECMAScript 5 is called JavaScript 1.8.5.
In this tutorial, we’re going to be looking at the JavaScript 1.8.5 functions that are available to us in the Firefox 4 betas. You’ll be happy to discover that most of the latest versions of other browsers have these, too . . . except for one. This time, it’s Opera, as IE9 has included many of these.

Function 1: Object.create

This method is a very important one; it really cleans up prototypal inheritance. Previously (in ECMAScript 3rd edition), to create an object and set its prototype

Function 2: Object.defineProperty

If you’ve got an object that you want to define a property on, you’ll probably do it this way:

1. my_dog.age = 2;  

my_dog.age = 2;

This still works fine in ES5, but if you want some more fine-grained control, you can have it with Object.defineProperty. The first parameter is the object you’re assigning the property on. The second parameter is the name of the property, as a string. The final property is the descriptor object. Here’s how that works. It’s (obviously) an object and it can have a combination of the following properties, all of which describe the property we’re adding:

• value: use this to set the value of a property. Defaults to undefined.
• writable: use this boolean to define whether this is a read-only variable. If it’s writable, it’s true. Defaults to false.
• configurable: use this boolean to define whether the type (value vs. method) of this property can be changed, or whether the property can be deleted. If it’s configurable, it’s true. Defaults to false.
• enumerable: use this boolean to define whether this property is included when the properties of the object are enumerated (a for-in loop or the keys method). Defaults to false.
• get: use this to define a custom getter method. Defaults to undefined.
• set: use this to define a custom setter method. Defaults to undefined.

Notice that the defaults for the boolean options above are the reverse of the old obj.prop = val standards. Also, know that you can’t define value or writable when get or set are defined, and vice versa.

Function 3: Object.defineProperties

If you want to define several properties at once, you can use a property descriptors object just as with Object.create to define them, using Object.defineProperties.

Function 4: Object.getOwnPropertyDescriptor

If you ever want to know the specifics of a property, you can use this function, Object.getOwnPropertyDescriptor. Take note of the “Own”; this only works with properties on the object itself, not up its prototype chain

Function 5: Object.keys

Ever wanted to get all the keys of an object? Now, you can do so easily with Object.keys. Pass this function an object, and it will return an array of all the enumerable properties of that object. You can also pass it an array, and you’ll get back an array of the indices.

Function 6: Object.getOwnPropertyNames

This one is just like Object.keys, except that it includes all the properties—even the ones that aren’t enumerable. By the longer function name, you can tell they discourage the use of it. Usually, you’ll want keys instead.

Function 7: Object.preventExtensions / Object.isExtensible

If you’ve ever wanted to create a function that doesn’t accept new parameters, you can do so now. Run your object through Object.preventExtensions, and it will decline all attempts to add new parameters. This function goes hand in hand with Object.isExtensible, which returns true if you can extend the object and false if you can’t.

Function 8: Object.seal / Object.isSealed

Sealing an object is one step up from preventing extensions. A sealed object won’t let you add or delete properties, or change properties from a value (like a string) to an accessor (a method) or vice versa. You’ll still be able to read and write properties, of course. You can find out if an object is sealed by using Object.isSealed.

Function 9: Object.freeze / Object.isFrozen

Freezing it yet another step further. A frozen object can’t be changed in any way; it’s read-only. You can verify the frozenness of an object with, you guessed it, Object.isFrozen.

Function 10: Array.isArray

You’d think that it wouldn’t be too hard to determine that a given variable is an array. After all, everything else works fine with the typeof operator. However, JavaScript arrays are of inconsistent ilk. They’re actually closer array-like objects (even though we usually use that term to refer to things like arguments and NodeLists). This function gives you a way to be 100% sure that what you’re working with is an array. Pass it a variable, and it returns the boolean.

Function 11: Date.prototype.toJSON

This isn’t too big, but if you ever want to store dates in JSON, you might find this useful. Date objects now have a toJSON function that will convert the date to a JSON string date.

Function 12: Function.prototype.bind

You’re probably familiar with using call and apply to reassign the value of this in a function.

But Wait, There’s More …

Those are the ECMAScript 5th Edition (or JavaScript 1.8.5) functions that have been added to the Firefox 4 betas. There are a few other changes to JavaScript that they are implementing as well, which you can check out in the release notes.
However, there are a bunch of ECMAScipt 5 functions that were already supported in Firefox 3, and several other browsers. Have you played with any of these?

• Object.getPrototypeOf
• String.prototype.trim
• Array.prototype.indexOf
• Array.prototype.lastIndexOf
• Array.prototype.every
• Array.prototype.some
• Array.prototype.forEach
• Array.prototype.map
• Array.prototype.filter
• Array.prototype.reduce
• Array.prototype.reduceRight

Apple Removes Jailbreak API From iOS 4.2

Apple has removed its built in methods to help developers detect jailbroken devices from iOS 4.2, according to NetworkWorld.
This detection API let the MDM applications in effect ask the operating system if it had been compromised. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.
Previously, developers had created their own series of operating system checks to detect jailbreak.
"We used it when it was available, but as an adjunct," says Joe Owen, vice president of engineering at Sybase, which offers the Afaria device management software. "I’m not sure what motivated their removing that….I’ve not had anyone [at enterprise customer sites] talk to me about this API being present or being removed."
In July of this year the Library of Congress deemed that jailbreaking your iPhone in order to install applications not approved by Apple and/or to unlock is legal.

Reset a user's password in single user mode

We needed to reset the password on a Leopard system, but we didn't have the OS X install DVD available. 

1. Boot into single user mode (press Command-S at power on)
2. Type fsck -fy
3. Type mount -uw /
4. Type launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
5. Type dscl . -passwd /Users/username password, replacing username with the targeted user and password with the desired password.
6. Reboot

This allows you to reset the password in single user mode without booting from the install media. 

Completely disable single user mode

A very simply way to disable single-user mode is to edit /etc/rc.boot (as root or with sudo) and in the section that prints "file system mounted read-only", simply add a line that says reboot Now, anytime the computer is booted in single-user mode, it simply reboots itself. 
This is totally non-bypassable because Apple disables any usable keys in the begining of the rc files. 

Change Mac admin password without the disk

Creating a new Admin on Mac Os X: 
Here's how to reset your OS X password without an OS X CD. 
the Working solution for me was to create a new admin 
you can create new admin like this by deleting a specific file. 

You need to enter terminal and create a new admin account: 

1. Reboot 
2. Hold apple key + s key down after you hear the chime. (command + s on newer Macs) 
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line): 

mount -uw / 
rm /var/db/.AppleSetupDone 
shutdown -h now 

4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and your good to go again! 

Apple stores wont reset it for you. Computer shops may charge you $50 to $200 trying to reinstall the Mac and failing at end.

rotate3Di - Flip HTML content in 3D

Rotate3Di is a jQuery Effect Plugin that makes it possible to do an isometric 3D flip or 3D rotation of any HTML content. It also enables custom 3D rotation animations. CSS3 Transforms are used to create this visual "3D" isometric effect. Supported browsers are WebKit, Safari, Chrome, Firefox 3.5+, IE9 (Platform Preview 7+), and probably Opera. The plugin's functionality includes: setting or animating HTML content to an arbitrary isometric rotation angle, as well as flipping, unflipping, or toggling the flip state of an object.
