  • Qt 6.0 RC1 Takes Flight - Qt 6.0 Should Be Here By Mid-December - Phoronix

    Qt 6.0 Release Candidate 1 has the latest batch of bug/regression fixes to the Qt6 code-base. The very basic Qt 6.0 RC1 release announcement can be read on the Qt development list.

  • Porting from Qt 5 to Qt 6 using Qt5Compat library

    Porting from Qt 5 to Qt 6 has been intentionally kept easy. There has been a conscious effort throughout the development of Qt 6 to maintain as much source compatibility with Qt 5 as possible. Still, some effort is involved in porting. This short post summarizes some of the steps required when porting to Qt 6.

    In Qt 5 some of the classes already had existing replacements, and some classes got successors during the Qt 6 development phase. Therefore it might make sense to be able to compile your code with both the old and new Qt version. This can ensure that the amount of work where your code does not compile with either version is minimized, allowing your application or library to continue to work with Qt 5 and Qt 6. Another advantage could be that existing unit tests continue to work for most of the duration of porting, and regressions resulting from porting your code are easily distinguished from bugs introduced in Qt 6.

Getting Started with Raspberry Pi Pico using MicroPython and C

Raspberry Pi Pico board was just launched last Thursday, but thanks to Cytron I received a sample a few hours after the announcement, and I’ve now had time to play with the board using MicroPython and C programming language. I went to the official documentation to get started, but I had to look around to achieve what I wanted to do, namely blinking some LEDs, so I’ll document my experience with my own getting started guide for Raspberry Pi Pico using a computer running Ubuntu 20.04 operating system. The instructions will be similar for Windows and Mac OS. Read more

Tiny Core Linux Installation and Review

The OS architectures supported by Tiny Core Linux are x86. X86_64, and ARM processors. It may not be a complete package for a functional Linux distro or flavor, but the freedom and flexibility it offers is out of the box. Under Tiny Core Linux, you get to push your OS around rather than your OS pushing you around like in other platforms. The speed and simplicity under this Linux distro cannot be substituted. Moreover, the absence of a Desktop environment distractions under its user experience is another plus. It gifts you the perfect tinkering experience due to its lightweight nature. Read more
