Повторяться, но каждый раз по-новому – разве не это есть искусство? Станислав Ежи Лец, из книги «Непричёсанные мысли» Словарь определяет репликацию как процесс поддержания двух (или более) наборов данных в согласованном состоянии. Что такое «согласованное состояние наборов данных» – отдельный большой вопрос, поэтому переформулируем определение проще: процесс изменения одного набора данных, называемого репликой, в ответ на изменения другого набора данных, называемого основным. Совсем не обязательно наборы при этом будут одинаковыми. Поддержка репликации баз...

Собеседование инженера программиста сегодня часто включает в себя некий тест или упражнение на программирование, и я думаю, что это очень плохая вещь. Вот почему. Ленивые тропы Попросив инженеров-программистов выполнить конкретную задачу, например написать алгоритм генерации факториалов (очень распространённый) или отсортировать односвязный или двусвязный список, которые легко запоминаются, вы не получите никакого представления об умениях кандидата, кроме умения зубрить. С таким же успехом можно спросить ASCII-код символа 'A'. Подробные решения многих задач легко найти...

Naming, but not in the way you think. Our knowledge represents a minute portion of reality. Names are the visible portion of that knowledge. Phil Karlton once said, “there are only two hard things in Computer Science: cache invalidation and naming things.” One is a real problem; the other is a problem of defining reality. A misbehaving cache algorithm compromises the system’s integrity. Inadequate names can compromise the system’s entire existence. On the surface, this...

Aha! There is always something intimidating about Dependency Injection. I distinctly remember a couple of years ago, telling a .Net recruiter for a contract project, that, “I had no idea what DI is” He immediately stopped talking to me. It’s just one of those moments. It was true, to an extent. It’s one of those things that you have been doing for years, but, you never knew you were doing it. Like how you...

What is pagination So you may have already used this one, but you may be wondering what this pagination 😀. So as in figure 1, pagination helps you break a large number of datasets into smaller pages. For example, a storybook contains 1000 pages. Why does it have 1000 pages instead of 1? To ease the reading. Same thing in here as well. Imagine you are dealing with a dataset that...

Martin, popularly known as Uncle Bob, credit for this idea in his 2000 work, Design Principles and Design Patterns. He’s also known for...

Database Setup with DbUp + Postgresql + Dapper in ASP.Net Core In this tutorial, we are going to explore how we can setup our database on startup when using Dapper for accessing database. When using Dapper, one of the key learning I came to know is that we have to have database and tables already created in advance in order to read/write data.

The developer needs to handle that exception otherwise the application will be terminated.   Every developer has their own way of handling the errors in their code.

From a software perspective, even 10 years begins to show its age. I started to use Web Forms the year after they were introduced by Microsoft in 2003. Most of my college years were spent in Web Forms and around 80% of my professional career has revolved around them...
