Первая программа для семилетки

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. Строгий... Read more

If we can efficiently search a record out of  many records, we easily perform different operations on that data. Hashing is storing and retrieving data from the database in the order of O(1) time. We can also call it the mapping technique... Read more

AWS, ELB, CDN, Autoscaling and other abbreviations and terms related to low-latency WebRTC

The modern browsers do not give users a choice between using WebRTC and not using it. And while you can playback streams using HLS or MSE, WebRTC remains the only tool for capturing camera feeds and publishing streams from a browser. 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

.NET Application Optimization: Simple Edits Speeded Up PVS-Studio and Reduced Memory Consumption by 70%

Here comes a question - how to find weak points that lead to excessive memory... Read more

Usually, the back-end is thought to be the ‘brains’ of a webpage and the front-end is merely the shiny exterior. However, with the right front-end development framework, powerful computations can happen directly on the front-end as well. Angular happens to be one of such impressive front-end development frameworks. Through its templates, Angular offers... Read more
