Array extras and Objects

2011-11-30T11:28:00.000-08:00

When Array extras landed in JavaScript 1.6 I had, probably together with other developers, one of those HOORRAYYY moment ...What many libraries and frameworks out there still implement, is this sort of universal each method that supposes to be compatible with both Arrays and Objects.A Bit Messed UpWhat I have never liked that much about these each methods is that we have to know in advance in any

About Felix's Style Guide

2011-11-27T06:26:00.000-08:00

Style guides are good as long as these are meaningful and a bit "open minded" because if one style is recognized as anti pattern then it must be possible to update/change it.The Felix's Node.js Style Guide is surely a meaningful one, but I hope it's open minded too.Why This PostBecause I write node.js code as well sometimes and I would like to write code accepted by the community. Since

JSONH New schema Argument

2011-11-26T03:52:00.000-08:00

The freaking fast and bandwidth saver JSONH Project has finally a new schema argument added at the end of every method in order to make nested Homogeneous Collections automatically "packable", here an example: var // nested objects b property // have same homogeneous collections // in properties c and d schema = ["b.c", "b.d"]

On Complex Getters And Setters

2011-11-25T12:41:00.000-08:00

A common use case for getters and setters is via scalar values rather than complex data.Well, this is just a programmer mind limit since data we could set, or get, can be of course much more complex: here an examplefunction Person() {}Person.prototype.toString = function () { return this._name + " is " + this._age;};// the magic identity configuration objectObject.defineProperty(

Differential Background Scrolling

2011-11-20T18:19:00.000-08:00

A quick one about this technique quite common in Flash sites but rarely seen on Web.Have a look at the example first so you can understand what I am talking about ... got it ?What Is This AboutLet's say we have a background, a big massive graphic background surely not suitable for mobile phones, due data roaming, but maybe cool for desktop and fast ADSL.The background-size CSS property is able to

Few JavaScript Patterns

2011-11-12T04:02:00.000-08:00

Just to be clear and once again, JavaScript can emulate:classespublic and public static methods or propertiesprivate and private static methods or propertiespublic and private constantsprotected methods... you name it ...// duck typing ( maybe all you need )var me = {name: "WebReflection"};// basic classfunction Person() {}Person.prototype.getName = function () { return this.name;};

Function.prototype.notifier

2011-11-08T14:33:00.000-08:00

There are way too many ways to stub functions or methods, but at the end of the day all we want to know is always the same:has that function been invoked ?has that function received the expected context ?which argument has been passed to that function ?what was the output of the function ?Update thanks to @bga_ hint about the output property in after notification, it made perfect senseThe

On User Agent Sniffing

2011-10-31T12:52:00.000-07:00

Oh well, who was following me on twitter today is already bored about this topic (I guess) but probably other developers would like to read this too so ...What Is UA SniffingUserAgent sniffing means that a generic software is relying into a generic string representation of the underlying system. The User Agent is basically considered a unique identifier of "the current software or hardware that

JS getCSSPropertyName Function

2011-10-25T12:51:00.000-07:00

I was re-checking @LeaVerou talk at jsconf.eu looking forward to see mine there too to understand how to improve and specially what the hell I have said for 45 minutes :DLea made many valid points in her presentation but as is for supports.property case, you never want to go too deep into a single point of your talk so ... here I come.getCSSPropertyName FunctionThis function aim is to understand

Playing With DOM And ES5

2011-10-19T22:32:00.000-07:00

A quick fun post about "how would you solve this real world problem".The ProblemGiven a generic array of strings, create an unordered list of items where each item contains the text of the relative array index without creating a singe leak or reference during the whole procedure.As plus, make each item in the list clickable so that an alert with current text content occur once clicked.The

Do You Really Know Object.defineProperty ?

2011-10-18T16:05:00.000-07:00

I am talking about enumerable, configurable, and writable properties of a generic property descriptor.enumerablemost likely the only one we all expect: if false, a classic for/in loop will not expose the property, otherwise it will. enumerable is false by default.writablejust a bit more tricky than we think. Nowadays, if a property is defined as non writable, no error will occur the moment we'll

The Missing Tool In Scripting World

2011-10-16T04:49:00.000-07:00

Few days ago I was having beers with @aadsm and @sleistner and we were talking about languages and, of course, JavaScript too.That night I have realized there is a missing process, or better tool, that could open new doors for JavaScript world.The Runtime NightmareThe main difference between scripting languages and statically typed one is the inability to pre optimize or pre compile the code

Object.prototype.define Proposal

2011-10-15T05:27:00.000-07:00

Somebody may think that defineProperties is boring and I kinda agree on that.The good news is that JavaScript is flexible enough to let you decide how to do that ... and here I am with a simple proposal that does not hurt, but can make life easier and more intuitive in modern JS environments.Unobtrusive Object.prototype.defineHow ToWell, the handy way you expect.The method returns the object

Depiction About Automation Systems

2011-10-13T01:11:00.000-07:00

Automation system is the use of control system and information technologies to reduce the need for human work in the production of goods and services. Pad printing, laser printing, home automation etc. are automation systems. Pad printing process is mainly using for move a 2D image on to a 3D object.

The Stark Differences Between Apple iCloud and MobileMe

2011-10-13T01:07:00.000-07:00

Are you curious about the differences between the iCloud and MobileMe? After all, aren't they both cloud services? MobileMe is Apple's current cloud software and it's a paid service that isn't very popular at the moment. Apple iCloud completely revamps the service and offers many more features. For one 5 GB of free cloud storage is available for every IOS account with IOS 5. MobileMe customers

about JS VS VBScript VS Dart

2011-10-12T22:23:00.000-07:00

You can take it as a joke since this is not a proper comparison of these web programming languages. JS Dart VBScripttypes √ √ sort ofgetters and setters √ √ √immutable objects √ √ √prototypal inheritance √simulated classes √"real" classes

about that post

2011-10-12T21:18:00.000-07:00

I have been blamed and insulted enough so I removed the possibility to comment and I also invite you again to do not stop reading the title of a generic post here or anywhere around the net.I would like to summarize few parts of that post:on real world we should use the proper flag in order to generate files where only necessary parts of the library is included...I agree that at this stage can be

What Is Wrong About 17259 Lines Of Code

2011-10-11T22:34:00.000-07:00

Is the most popular, somehow pointless, and often funny gist of these days.It's about Dart, the JavaScript alternative proposed by Google.Why So Many Lines Of CodeThe reason a simple "Hello World" contains such amount of code is because:the whole library core is included and not minified/optimized but on real world we should use the proper flag in order to generate files where only necessary

Taking The Bat-Formula To The Next Level

2011-10-09T03:45:00.000-07:00

When you wake up on Sunday morning with upside-down stomach and batcode in mind, you may realize it's time to rest a bit.with (/*Bat*/Math) Array(16).join( pow(/*JOK*/E/*R*/, cos, E/*vil*/)) + "batman";The output is the same produced by the original bat-formula:'NaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNbatman'Have a nice Sunday.

A Better is_a Function for JS

2011-10-09T02:48:00.000-07:00

In 2007 I have posted about get_class and is_a functions in JavaScript in order to simulate original PHP functions.Well ... that was crap, since a much simpler and meaningful version of the is_a function can be easily summarized like this:var is_a = function () { function verify(what) { // implicit objet representation // the way to test primitives too return this instanceof what; }

implicit require in node.js

2011-10-06T02:36:00.000-07:00

playing with Harmony Proxy I came out with a simple snippet:The aim of above snippet is to forget the usage of require ... here some example:module.sys.puts("Hello implicit require");var fs = module.fs;fs.stat( ... );It's compatible with nested namespaces too and if there are non JS chars in the middle ... well:var Proxy = module["node-proxy"];

bind, apply, and call trap

2011-10-05T03:27:00.000-07:00

quick one out of ECMAScript mlvar // used to trap function calls via bind invoke = Function.call, // normal use cases bind = invoke.bind(invoke.bind), apply = bind(invoke, invoke.apply), call = bind(invoke, invoke);What Is ItThis is a way to trap native functions method in a handy way. Used in a private scope, it can address these methods once so that we can rely nobody can

Dear Brendan, Here Was My Question

2011-10-03T00:17:00.000-07:00

I had the honor to personally shake the hand of the man that created my favorite programming language: Brendan Eich!I also dared to ask him a question about ES6 and I would like to better explain the reason of that question.I have 99 problems in JS, syntax ain't oneI don't know who said that but I completely agree with him.Here the thing: one of the main ES6 aim is to bring new, non breaking,

An Introduction to JS-Ctypes

UpdateIf you have time follow the whole story in es-discuss mailing list while if you don't have time here the quick summary:js-ctypes purpose is different from JS.next typed structs/arrays so it looks like it was my mistake to compare tomatoes and potatoes.I bet everybody else in this world could have compared these two different beasts due identical name, look, and similar usage.If ctypes are

My New Programming Language

2011-09-10T01:03:00.000-07:00

yeah, you read it correctly ... we all need another better programming language because everything we've done until now sucks.What Sucksthe fact we don't learn by mistakes, which means all of us should instantly try to create a new "secretly open source programming language" so that the rest of the world can only endure it once it's out, rather than contribute to make it better/needed as it's

2011-08-24T11:35:00.000-07:00

Well, not only downloads on the fly, the data uri works for almost everything ( only iOS 5 beta does not want to work with inline data uri AUDIO sources .... but this is another story ... ) ... so ... How To Simulate Script injectionLet's say you want a test but you don't want to bother a server. However, you want to be sure the test is asynchronous and it simulates the server.var head =

Overloading the in operator

2011-08-20T01:39:00.000-07:00

In all its "sillyness", the CoffeeShit project gave me a hint about the possibilities of an overloaded in operator.The Cross Language AmbiguityIn JavaScript, the in operator checks if a property is present where the property is the name rather than its value."name" in {name:"WebReflection"}; // trueHowever, I bet at least once in our JS programming life we have done something like this, expecting
