19 июня Qt Company выпустили Qt 5.13. Как всегда, релизы поставляются с новыми функциями, обновлениями, исправлениями ошибок и улучшениями. В Qt 5.13 Qt Company также сфокусировались на инструменте, который делает проектирование, разработку и развертывание программного обеспечения с Qt более эффективным как для дизайнеров, так и для разработчиков. Давайте рассмотрим некоторые основные моменты Qt 5.13, а также некоторые обновления в части инструментов.

Qt 5.12.4, четвертый выпуск патча Qt 5.12 LTS, выпущен сегодня. Релиз Qt 5.12.4 содержит ряд исправлений ошибок, а также улучшение производительности с рядом других улучшений. В качестве важного нового элемента он обеспечивает сборку двоичных файлов с OpenSSL 1.1.1, включая новую функциональность TLS 1.3.

Good day! For a long time I was going to add a new functionality on the site and finally this time has come.

Launched alpha version of modules companies and vacancies on EVILEG. Now users can add their companies to the site and place vacancies on behalf of these companies.

Good day! I am happy to present the first release of the EVILEG Social Network Framework - Core (ESNF-C).

The release is version 0.0.3. I successfully spent the first two versions on setting up the release in PyPi so that I could install the package not only from the repository or manually build it, but I would use the opportunity to install it through the pip utility.

pip install evileg_core

In the process of developing a project on Django, we may encounter an unpleasant situation when some packages and modules were removed and, accordingly, models from these packages were no longer used. But at the same time, squash of application migrations does not allow removing these packages, since migrations have many circular dependencies. As a result, removing unnecessary packages becomes a rather difficult task. Since resolving such dependencies becomes a non-trivial task. For me, such an unpleasant package was Django CKEditor, which was present almost everywhere. As a result, this package due to migrations remained for quite a long time in the list of requirements.txt, although in fact it was not used on the site at all.

I would like to share one of the possible way for moving the data model from one application to another.

Immediately, I note that this version of the data model transfer is not 100% working and you may need additional manual editing of the tables to correctly set the Content Type. Since any such modifications are fraught with data loss for GenericForeignKey relationships.

In my case, GenericForeignKey was not used, so there was no such problem.

I propose to consider the process of installing and configuring a Django project on Mac OS X based on an existing project.

Some steps will be similar to those already performed in the Django setup article for Ubuntu .

Данная статья приурочена к старту курса "Алгоритмы для разработчиков" от компании OTUS. Выражаю признательность за поддержку ресурса данной компанией.

Давайте изучим, какие операции можно выполнять со связанным списком.

Два важных момента, которые нужно помнить:

• head указывает на первый узел связанного списка
• next указатель последнего узла равен nullptr , поэтому, если следующий из текущего узла равен nullptr , мы достигли конца связанного списка.

Note, not to forget, how quickly through the terminal to set recursively 755 access to directories and 644 files.

Qt is quite a large framework and it constantly introduces functionality, which unfortunately either do not have time to document or forget to document.

For example, besides the QQuickItem documentation, I highly recommend watching the sources, or at least the header files. Wonder how many public methods are there that are not described in the documentation, but can be successfully applied, and are very useful in a word.

But now the talk will be about copying files using the functionality that was implemented in Qt 5.6, but at the same time almost nothing is known about it.
