Alexa’s Traffic Ranks are based on the traffic data provided by users in Alexa’s global toolbar panel over a rolling 3 month period. Traffic Ranks are updated daily. A site’s ranking is based on a combined measure of Unique Visitors and Pageviews. Unique Visitors are determined by the number of unique Alexa users who visit a site on a given day. Pageviews are the total number of Alexa user URL requests for a site. If your site’s metrics are Certified you can display Global and Country ranks for your site based on Certified Site Metrics, instead of metrics from our toolbar panel.

Alexa’s Traffic Ranks are for top level domains only (e.g., For more detailed information about Alexa’s traffic rankings, you can visit: There are limits to statistics based on the data available.

If you’ve ever spent hours combing Wikipedia for information about a topic, opening up tab after tab to compare different pages, then you’ll appreciate Silk.

Silk is an app for the web that wants to help you collect, sort and view the information that you need without making you comb through the data yourself. Think of it as an intern that knows everything about a given subject and can deliver that information to you with minimal effort. Silk can be used in a couple of different ways. The first way is that it can be seeded with data from other sites. Wikipedia, IMDB and CrunchBase are examples of sites that have a lot of data about given topics. Unfortunately, those sites can be tedious to navigate and it’s time consuming to pull out the specific data that you’re interested in. Here’s an example, lets say you wanted to find out which companies were sold for over $1B that had founders over the age of 40 when they were started.

No hace muchas fechas, expliqué el uso de solver, para calcular la TIR (Tasa Interna de Rentabilidad, o Tasa Interna de Retorno) de una operación financiera. Lo hice de la forma más complicada, con la única excusa de mostrar como funciona solver. Quienes hayan estudiado programación lineal, sabrán que esta ulitidad que incorpora excel, nos sirve para optimizar (maximizar o minimizar), utilizando restricciones, sin tener que hacer complejos cálculos matemáticos. Solver es algo así como una miniaplicación, dentro de otra aplicación, en este caso, excel. Yo soy más dado a utilizar las fórmulas de matemáticas financieras, para determinar la rentabilidad o el coste de una operación, en lugar de utilizar las fórmulas que excel incorpora y que permiten ahorrarnos ese trabajo (aparte de que también nos permiten olvidarnos de las complicadas matemáticas financieras).

Hoy vamos a hacer uso de esas formulitas, para determinar la TIR y el VAN de una operación financiera. PDF Converter — #1 Free PDF Creator — PrimoPDF. DaDaBIK, créer des frontends personnalisés de base de données. Tous les développeurs ou presque connaissent les frondends du type PHPMyAdmin, qui permettent d’administrer une base de données, moyennant quelques connaissances.

DaDaBIK, créer des frontends personnalisés de base de données

Mais pour les utilisateurs novices, imaginer créer des frontends personnalisés s’appuyant sur une base de données relève du fantasme. DaDaBIK est une application open source écrite en PHP qui permet de créer des applications pour utiliser les données d’une base, sans avoir à coder une ligne. L’idée consiste à découvrir toutes les tables et les champs d’une base, et de construire un environnement pour requêter ceux-ci, le tout sans écrire une ligne de code. Il est même possible d’extraire des champs complexe (blob, …) et de visualiser le contenu (par exemple une image).

Tout se passe grâce à la couche d’abstraction PDO.
