Card counting in blackjack

Where in other casino games such as roulette, craps there is no absolute effect of result of one play on any future deal, the blackjack always remain some risks regarding that. That means in blackjack it is possible that some events of any future play can be affected by its previous performance. Whenever if it is found that the remaining cards of the player have a high proportion than normal, in that case it is quite obvious that it goes to player’s benefits but in adverse the player will dealt a bad hand of cards. But in many cases it has been found that it is very tough for the player to remember exactly which cards have already been dealt in the previous play. Especially it becomes difficult when it comes from a multiple deck shoe. For that reason card counting always denotes some positive, negative or zero point value to the each and every remaining card in the deck.

Generally it is seen that the cards carrying low value such as 2, 3 are of positive value and the cards carrying higher value are at the negative value. But the different card counting method assigns different value of each card to be dealt. The card counter can make a tally of the point values in his mind although it is better to make a count on counter’s own estimation regarding dealt cards and undealt cards as well. That will definitely present an accurate value or proportion or percentage of the cards which have been left in the deck shoe. Keep in mind that a larger range of point values always make the counting process complicated. Counting process of the card valued the smaller value such as 1, -1, 0 is level one count that denote the most easiest task of performance while multilevel count is what assign the higher point values, increase much difficulty.

In the process of card counting in blackjack the main complication remain in the treatment of aces which is much valuable when it comes for having a blackjack. Generally aces are not advantageous for the card players but it is beneficial when it is in the field of blackjack and remains in the deck. It should have a positive count.

The main advantage that a player can get through this card counting formality is that the player can make more betting of larger portion when his deck of card allows him and in adverse the deck itself  give signal to make smaller amount in betting and accordingly can modify its situation by taking other various strategies. The player can also get information relating to value of each and every card to be dealt in or any type of composition that will help to make a better result.

The very main thing about this card counting is that the method of card counting will be performed very genuinely and accurately so that it cannot make any negative effect and with this the counting process must be taken to avoid the casino countermeasures. Otherwise many can make errors in this process and lose huge amount of money as well.

Advergaming: Advertising through video games

The practice of using video games to promote a particular product or an organization is known as “Advergaming”. Wired magazine first used this term in a column to describe the commissioning of free online games by large companies, in 2001. There are three categories of Advergaming: ATL Advergaming, BTL Advergaming and TTL Advergaming.

ATL Advergaming can be vaguely explained as a promotional video game. The business incorporates interactive video games on their website so as to create more awareness about their product among the website visitors. This method is also used to attract more visitors to the site and to increase the traffic flow on the website. If the games are made for product advertising, the product is highlighted in the game.

Before the invention of the internet, floppy disks and later compact disks were used as a medium to promote games and in turn a particular product. It started with floppy disk basically to create awareness as well as product promotion. The first Advergame was distributed by American Home Food, which was developed by Chef Boyardee. Taco Bell and Coca Cola followed it by giving customers floppy disks containing promotional games. The first Advergame to be distributed on compact disk was by Chex and General Mill. The graphics of these games have matured from arcade style flash to three-dimensional.

BTL Advergaming comprises of recruitment tools like In-game advertising, militiamen and edutainment. Usually the mascot of the particular company is depicted as the hero in such games. Pepsi man and Burger man were the mascots used in promotional games designed by Pepsi and Burger King respectively. The storyline of these games can be commercial, educational or political like the game American Army created to attract more youth towards devoting their life to army and also games meant to promote sports like Formula One racing are also a part of this technique.

In-game advertising is more commercial type and is purely targeted for promotion of the product via the game. This is really picking up and even movies are promoted by this method. Like on the website of the movie, The Mummy, there are games which have a storyline similar to the movie and the player is given knowledge of the facts about the movie and its subject, Egyptian Mummy. Educational Advergaming refers to games that portray a moral message to the players.

These games can also act as a medium of advertisement themselves like in the video game of EA Sports; banners of Pepsi line the frame of the game. By using this strategy the companies are able to provide low price or free games to the consumers.  This is also effective in reducing the price of games that have a monthly fee.

TTL Advergaming or through the line Advergaming is the most rare form of Advergaming. URL links are embedded into a game that takes the players to the web pages, which has BTL Advergaming. Different methods are used to attract the player to a particular webpage. In the game ” Enter the Matrix” URL hyperlinks are depicted in the background, which the player is forced to click to learn about the facts relating to the plot of the next level and at the same time advertises about the product. The curiosity to learn about the theme of the game attracts the player, although it might not be necessary to click to finish the game.  Such kinds of games are usually known as link-chases as one link will lead to another. Website visitors are sometimes tempted with a prize to prompt them to click the URL.

This technique of advertising is really beneficial as it not only creates awareness among the player but also among his friends who lands the website upon friend’s suggestion. The success of Advergaming is dependant on word of mouth and thus is also known as viral marketing. In the year 2004, this industry generated around $83.6 million and involved 105 million players.

La différence entre Android et Apple du point de vue d’un développeur

La guerre des systèmes d’exploitation de téléphones portables est principalement concentrée entre  d’iOS et  d’Android. Chacun ayant les meilleurs arguments du monde pour prouver à l’autre  que son téléphone c’est le  plus mieux et meilleur du monde .

Kek développe depuis une dizaine d’années des petits jeux originaux en Flash, dans un esprit très drôle et assez irrévérencieux le genre d’esprit que j’apprécie.

A l’occasion de la sortie de son premier jeu sur téléphone portable, il revient  sur le processus de développement, et sur ce qui lui a plu ou déplu chez les deux systèmes d’exploitation adverses .

A quoi sert la mémoire vive ?

La mémoire vive  permet de stocker les informations dont l'ordinateur a besoin rapidement et dont il se sert souvent. Lorsque vous ouvrez un programme, celui-ci est stocké dans la mémoire vive de votre PC, qui dispose d'un accès beaucoup plus rapide que le disque dur. Pourquoi ne pas avoir utilisé de la mémoire vive dans ce cas pour stocker les données ? C'est très simple : la mémoire vive est volatile. Une simple perte de courant et elle perd toutes ses informations ! De plus, son coût et son encombrement sont bien plus élevés que ceux d'un disque dur.

Fonctionnement de la mémoire vive (RAM)

La mémoire (RAM) se présente sous forme de composants électroniques ayant la capacité de retenir des informations . Chaque "bit" mémoire est composé d'un transistor  accouplé à un condensateur . La mémoire est organisée sous forme de lignes et de colonnes. A chaque intersection correspond un bit de mémoire. Voici la représentation d'un bit :

Les condensateurs se déchargent (leur tension diminue), il est nécessaire de les recharger pour éviter les pertes d'informations. On appelle cela le rafraîchissement. Une barrette de mémoire est constituée de trois éléments principaux : 

• La mémoire proprement dite (en réalité plusieurs tableaux de bits mémoire)
• Un buffer (zone de tampon) entre la mémoire et le bus de données
• Le bus de données (qui est relié à certains pins (contacts) de la barrette et est en relation avec la carte-mère)

systeme d'exploitation

système d'exploitation

Un système d'exploitation est un logiciel qui est dans un appareil électronique, pilote les dispositifs matériels et reçoit des instructions de l'utilisateur ou d'autres logiciels . Ces logiciels doivent être adaptés à un système d'exploitation.

Le rôle du système est gère  les processeur ainsi que la mémoire. Il fait fonctionner les périphériques (clavier, souris, surface tactile, écran, disque dur, lecteur de DVD lecteur de cartes mémoire...). Dans un appareil photo, il fait fonctionner les différents mécanismes, gère l'affichage de l'écran et détecte les actions de l'utilisateur. Il comportent  aussi l'interface avec l'utilisateur. Dans un ordinateur par exemple, c'est lui qui affichera les fenêtres et présentera le contenu des unités de stockage (disque dur ,DVD,...).
