Re: Challenge 1 | Callbacks | Async Programming

marcoslhc — Sat, 28 Jul 2018 21:08:22 -0000

The definition of "callback" is NOT "a function that returns nothing", that the value returned by a callback function is lost is the consequence of having a mechanism to respond to an operation in an asynchronous context. A "callback" can return any value, but the value is lost; the function's property of returning (or not) a value doesn't have anything to do with its condition as a callback. You could have a function that returns something passed as a callback.

The definition of a callback is: any function passed as a parameter to another receiver function with the explicit goal of notify the execution of the receiver or capture the result of the execution of the receiver.

Another thing: Null and Undefined are values (and types) in JavaScript. when you don't explicitly return in a function JavaScript returns "undefined". If you want to get "Null" from a function you have to explicitly express "return null" in the function.

Some other misleading concepts I found in the first exercise:

(x) => (x, console.log(x)) by your definition that a function that returns undefined "returns nothing", this case actually returns "nothing" Console.log returns undefined and after the comma operator the last expression is console.log
(x) => () => { fn(x * 2) } returns a function that returns undefined therefore the first function does return a value different that null or undefined

Depends on the immutable implementation. If it's using Immutable.JS or Baobab it can actually be faster than working with native JSON objects

Sorry, the "[..] user uses window." opinion was from css-trick.com. And, in regard of the other comment, I think it's shallow because is not about what tools makes you or your work more comfortable, productive, secure or safe. For me it sounds like you are putting your locus of control in the outside, on how other people behave. Sound like: "I don't want to be like anyone else in de web-dev world" https://uploads.disquscdn.c...

Chosing your dev environment just because you want to step apart from the "monoculture" is a rather shallow reason in my opinion. and the "because the final user uses windows" is ludicrous in term of web development.

Re: Python Tornado Web Server With WebSockets – Part I

Noted. You're right. I shouldn't advice not to allow cross-origin altogether, but instead recommend adding other security measures.

Hi. The "WebSocket connection to 'ws://localhost:8080/?Id=123456789' failed: Unexpected response code: 200" error can be solved by overriding check_origin (see http://tornado.readthedocs..... Note that this is recommended in this simple, tutorial, not-for-production case. When In production you shouldn't be accepting all cross-origin connections.

Led Zep was a lot more than blues based rock, they enhanced the meaning of "Folk Rock" including elements of british and celtic music. They took narrative lyrics way far the other rock bands and way before Black Sabbath. They innovated sound crafting recording experimenting with different kinds of environment and taking a "hands on approach" instead of pure delegation in engineers or producer. And I'm just starting… The song craft and technique was innovative too, Rober Plant's Classic formation was the first stone in elevating Rock Music above mere pop expression to actual meaningful cultural expression… Oh My God the Bonham drums, no one played that primal sound in a rock song, ever.

"Urban Hymns" is an album from The Verve, actually pretty good but not to make this list IMHO. "Definitely Maybe" is Oasis' debut album, not as good as "Urban Hymns". Queen's album "Sheer Heart Attack" is not as good as the rest of queen's albums but it shaped the now ultrafamous band. Finally "Country Life" from Roxy Music actually made the list at #350 or so.

No. No estamos en dictadura, los poderes establecidos han actuado conforme al consentimiento de la mayoría. Lo que si sufre Venezuela es un estado de miseria política y hasta humana. Nos aqueja la falta de gente preparada para gobernar y gente con conciencia y respeto por el colectivo que llamamos nación. En mi opinión, esa es la causa de por que no ha habido socialismo en Venezuela.

Espero que MAS NUNCA tengamos un líder como Chávez. Mi sentido pésame, por qué sé que fué una figura importante en tu vida. En la mía también lo ha sido durante 14 años e igual estoy confundido respecto al futuro de nuestro país, pero mi esperanza es que más nunca necesitemos un instigador como líder para darnos cuenta de la pobreza política de nuestro país.

Overall is the most accesible tutorial in Node.js, express and MongoDB. For the non initiate is the best tutorial around, I thanks the author and collaborators for that.
I'm not initiated in Node.js, i'm just an apprentice but in JavaScript I'm quite experienced and I can tell this is not the most elegant code i've seen. It works in a very very cared environment but sure it will explode in the wild.

"Who’s value to you on Twitter"
Kinda hard take THE ONE if you ask us that question, I include in my twitter just graphic-design-related people, some friends and family. I think the twtitterverse is more than this, so if you want to be just ONE left yok have to ask less subjective questions.
BTW who I value the most in twitter is Jacob Cass (@justcreative).

Re: Why MooTools (or Why not JQuery)

Re: Why MooTools (or Why not JQuery)

marcoslhc — Wed, 01 Oct 2008 11:27:15 -0000

I've never used mooTools. But I have some replies to say about two of the critics you made to jquery.
About the "Class Support", JavaScript (or ECMAScript) is a Object Oriented Language, but its object model is not "Classical" it's "prototypical". For many years people tried to use and teach Javascript as kinda subset of Java or C++ but, in fact, the philosophy behind JavaScript is totally different. It was meant to extend the behavior of a client app like the browser, so you don't really need classes with native data types, you just need Objects that extends functionality established in the DOM prototypes or the browser prototypes. In this philosophy is important also to bind names and make callbacks 'cause you never work with native data files on client machines (except for cookies with their limited uses), they are an efficient way to work further with data after it have been sent and previously manipulated. The "chain" (or what you call "SQL-like sintax") is actually a real good way to represent and understand the nature and function of binds and callbacks.
About the "Prototype Approach", I think in the long term, specially if you work in a team having unobtrusive code is way too important, even more important than file sizes, it's a matter of scalability. I will defend jquery in this saying that more than a function library, jquery is a Framework with its own model and methodology, it have its own method to apply and extend the models and functions proposed by its author. That's why the whole namespace and wrapping thing. If you want "shorter, natural code" stick with a library with "Prototype Approach", if you want a team-friendly environment to develop scalable javascript interfaces and applications, a framework with its own namespace.
