Les suites numériques sont liées à la mathématique de la mesure (mesures d'un phénomène prises à intervalles de temps réguliers) et à l'analyse (une suite numérique est l'équivalent discret d'une fonction numérique). La notion de suite est présente dès qu'apparaissent des procédés illimités de calcul. On en trouve, par exemple, chez Archimède, spécialiste des procédés illimités d'approximation (séries géométriques de raison 1/4) pour des calculs d'aires et de volumes, ou en Égypte vers 1700 av. J.-C. et plus récemment au I^er siècle ap. J.-C. dans le procédé d'extraction d'une racine carrée par la méthode de Héron d'Alexandrie :

For Hun Sen, 30 Turbulent Years as Prime Minister

Thirty years ago today, Hun Sen, then 33, was appointed prime minister by the National Assembly of the socialist People’s Republic of Kampuchea, becoming the world’s youngest head of government.
For the former Khmer Rouge regiment commander, who had fled to Vietnam in June 1977 amid a wave of purges by Pol Pot, it was the start of a reign in which he would traverse almost constant upheaval to impose himself as the unrivaled ruler of Cambodia.

The International Mathematical Olympiad (IMO) is an annual six-problem, 42-point mathematical olympiad for pre-collegiate students and is the oldest of the International Science Olympiads. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980

How To Install nodeJs Using a PPA

An alternative that can get you a more recent version of Node.js is to add a PPA (personal package archive) maintained by NodeSource. This will probably have more up-to-date versions of Node.js than the official Ubuntu repositories.

First, you need to install the PPA in order to get access to its contents:

curl -sL https://deb.nodesource.com/setup | sudo bash -

The PPA will be added to your configuration and your local package cache will be updated automatically. After running the setup script from nodesource, you can install the Node.js package in the same way that you did above:

sudo apt-get install nodejs

The nodejs package contains the nodejs binary as well as npm, so you don't need to install npm separately. However, in order for some npm packages to work (such as those that require building from source), you will need to install the build-essentials package:

sudo apt-get install build-essential
