Скачать или смотреть Codeigniter From Scratch - Database Selection Methods

After numerous requests, today we are launching a new screencast series on Nettuts+ that will focus exclusively on the CodeIgniter PHP framework.

Over the course of about 10 videos, I'll teach you exactly how to use this framework. Ultimately, we'll work our way up to building a custom CMS. Without further ado, here's day one!

The Scratch Wiki is a collaboratively-written wiki available for free that provides information about the Scratch programming language and its website, history, and phenomena surrounding it. The wiki is supported by the Scratch Team, but is primarily written by Scratchers. The Scratch Wiki is a popular source of information for scripts and tutorials, and it continues to grow as Scratchers use it as their primary source of information. This could also include advanced articles for Scratchers around the world to build, share, and see.
On December 6, 2008, LukeTek created the Scratch Programming Wiki, a normal wiki created solely by himself; the Scratch Team was not involved at all. He handed the wiki (gave admin privileges) over to JuiceyBox, who later handed the wiki to Lucario621. Lucario621 advertised the wiki in the Miscellaneous forum, and many people helped contribute to it. However, the articles were of projects, users, and the like. The wiki was cleaned up, but by then people had lost interest. A few people stayed behind though, and the wiki steadily grew.

Eventually, the Scratch Team saw the wiki. They liked it and wanted to advertise it on the Scratch Website, but they had some concerns: it had advertisements, it wasn't on a scratch.mit.edu domain, and there was no way to tell if a user on the wiki was the same user on Scratch. To solve these problems, andresmh, JSO, and Lucario621 created a new Scratch Wiki, hosted on the Scratch servers.[1] All three problems were solved: there were no advertisements, it was on a scratch.mit.edu domain, and there was a way to ensure that users on the wiki were the same users on Scratch: Account creation was locked; people would request for an account instead.
How to Become a Contributor

If people could freely create accounts, it would be possible to impersonate other users by creating an account with their username. To work around this, Scratchers must request for an account.

To request an account, Scratchers go here and request for an account. You will be asked to comment a verification code on a project. This is simply to make sure that you are who you say you are.

If the administrators create the account (can take up to several days, but it is often shorter), then the user will be told on their profile by an administrator. The user can then log in with the username and password they decided when requesting the account.

Not all accounts are created — administrators review all account requests, and decide whether to create the account. Having no projects will dramatically decrease the chance of a user getting a Wiki account, as will not giving a reason, or giving an extremely brief reason. One's reason should explain why they think they should get an account, what experience they have and any other information if the user wishes. The reason, the correctness of grammar and spelling in a user's reason, and the amount of experience a user has all go into deciding whether an account is created.
