Большой Короткомордый Медведь, он же Матти, он же Матс, он же Мэтью, он же неугомонный сын №3, решил на старости лет научиться программированию. И, для начала, написать какую-нибудь игрушку. Ну что же еще писать, кроме игрушек, правда? Текстовая игра «Матс или Мишка» (вариант «орел-решка») на Питоне его не особо порадовал: «Вот если б какие-нибудь автогонки»… Поскольку строгий папа обещал, что в собственноручно написанные игры можно будет играть без ограничений.

We can also call it the mapping technique... Read more

The browser developers have accepted this "format" and integrated it into their products – just as they used to support the Flash Player as a plugin. The only difference... Read more
