Canonical link element. A canonical link element is an HTML element that helps webmasters prevent duplicate content issues by specifying the "canonical" or "preferred" version of a web page as part of search engine optimization.
It is described in RFC 6596, which went live in April 2012. Duplicate content issues occur when the same content is accessible from multiple URLs. For example, would be considered by search engines to be an entirely different page from even though both URLs return the same content. Another example is essentially the same (tabular) content, but sorted differently. Canonical tags can also be useful to solve www and non-www duplicate content—where two URLs, identical except that one begins with "www" and other does not, point to the same page. This particular problem can be solved by proper use of the canonical tag. According to Google, the canonical link element is not considered to be a directive, but a hint that the web crawler will "honor strongly". Examples Git Tutorials and Training. Tomasz Kowalczyk.

Popular engines focus on the full-text indexing of online, natural language documents. Media types such as video and audio and graphics are also searchable.
Meta search engines reuse the indices of other services and do not store a local index, whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Larger services typically perform indexing at a predetermined time interval due to the required time and processing costs, while agent-based search engines index in real time. Indexing The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query.

Concurrent Versions System - Adding, removing, and renaming files and directories. Go to the first, previous, next, last section, table of contents.
The way that you remove a directory is to remove all the files in it. You don't remove the directory itself; there is no way to do that. Instead you specify the ‘-P’ option to cvs update or cvs checkout, which will cause CVS to remove empty directories from working directories. (Note that cvs export always removes empty directories.)

No CAPTCHA can survive a human that's receiving financial incentives for solving it, and with an army of low-waged human CAPTCHA solvers officially in the business of "data processing" while earning a mere $2 for solving a thousand CAPTCHA's, I'm already starting to see evidence of consolidation between India's major CAPTCHA solving companies.
The consolidation logically leading to increased bargaining power, is resulting in an international franchising model recruiting data processing workers empowered with do-it-yourself CAPTCHA syndication web based kits, API keys, and thousands of proxies to make their work easier, and the process more efficient. One of the services in question is the India based decaptcher.com, which will allow you to retrieve its API once you put. Displaying reCAPTCHA Without Plugins - reCAPTCHA.

Haanga - über efficient template engine for PHP. PHP Template Engine Comparison « Gonzalo Ayuso. I’m going to face a project using a template engine with PHP.
Because of that I’m will perform a small benchmark test of several PHP template engines. That’s not an exhaustive performance test. It’s only my personal test. Template engines has a lot of features but I normally only use a few of them and the other features very seldom. In this performance test I will check the same features under different template engines to see the syntax differences and the performance.
Atom. How to select the first/least/max row per group in SQL at Xaprb. Here are some common SQL problems, all of which have related solutions: how do I find the most recent log entry for each program? How do I find the most popular item from each category? How do I find the top score for each player? In general, these types of “select the extreme from each group” queries can be solved with the same techniques. I’ll explain how to do that in this article, including the harder problem of selecting the top N entries, not just the top 1. This topic is related to numbering rows, which I just wrote about (see my articles about MySQL-specific and generic techniques to assign a number to each row in a group). +--------+------------+-------+ | type | variety | price | +--------+------------+-------+ | apple | gala | 2.79 | | apple | fuji | 0.24 | | apple | limbertwig | 2.87 | | orange | valencia | 3.59 | | orange | navel | 9.36 | | pear | bradford | 6.05 | | pear | bartlett | 2.14 | | cherry | bing | 2.55 | | cherry | chelan | 6.33 | +--------+------------+-------+
As example of its capabilities, the File API could be used to create a thumbnail preview of images as they're being sent to the server, or allow an app to save a file reference while the user is offline. Additionally, you could use client-side logic to verify an upload's mimetype matches its file extension or restrict the size of an upload.
