KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt
-
CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings.
As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.

The KDE/Qt-aligned Krita digital painting program has published the first beta of their next feature release, Krita 4.1.

At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.)
For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student.
It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action.
If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.

As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.

Games: XENONAUTS 2, Make Sail and More
-
I've been having an internal debate with myself about covering this one, since I'm a huge fan of XCOM-like games but the developer of XENONAUTS 2 isn't yet fully committing to a Linux version.
-
I'm still terrible at it but there's a lot of charm to Make Sail [Steam] and the steady improvements have been impressive. This latest update is a rather nice one.
-
Directly helping to bring games to Linux can be super complicated - I’m talking low-level, real-time, writing-a-GUI-in-Visual-Basic-to-hack-the-Gibson complicated. What if there was a way to support the platform you love with just your regular old self? After years of stringent Meditation, Study and Calculations™ I’ve come to a miraculous conclusion: without even getting close to finding yourself stuck in vim, you can actually make a difference! Hear me out, friend.

Strategic RPG 'For The King' is a game that constantly surprised me with some really great gameplay. Thanks to the developer, I had a chance to check out For The King a little while ago and I keep going back for another run because it's so good.
| Programming: Zapcc C++, PHP and Python
-
Here are some quick benchmarks I ran this week of the newly open-sourced Zapcc C++ caching compiler based upon LLVM/Clang and compared to the upstream Clang performance, GCC, and Ccache with the speed on the original compilation of the benchmark code and then again on a subsequent compilation.

PHP team is glad to announce the release of the first PHP 7.3.0 version, PHP 7.3.0 Alpha 1. This starts the PHP 7.3 release cycle, the rough outline of which is specified in the PHP Wiki.
-
Just shy of two weeks since PHP 7.3 went into alpha, the second alpha release of this upcoming annual feature release to the PHP programming language is now available.
PHP 7.3 has been working on several new functions, WebP support within the image create from string function, improved PHP garbage collection, and a variety of other features and improvements. While PHP 7.3 is still open for new features, PHP 7.3 Alpha 2 comes with just bug fixes. Bug fixes for alpha two range from core fixes to various bugs in its ZIP, EXIF, Date, and CLI code, among other areas. The fixes are outlined here.

In a short session at the 2018 Python Language Summit, Steve Dower brought up the shortcomings of Python virtual environments, which are meant to create isolated installations of the language and its modules. He said his presentation was "co-written with Twitter" and, indeed, most of his slides were of tweets. At the end, he also slipped in an announcement of his plans for hosting a core development sprint in September.

One of the larger features added to Python over the last few releases is support for static typing in the language. Static type-checking and tools to support it show up frequently as topics at the Python Language Summit (PLS) and this year was no exception. Mypy developers Jukka Lehtosalo and Ivan Levkivskyi gave an update on static typing at PLS 2018.
Lehtosalo started things off by talking about stub files, which contain type information for libraries and other modules. If you are going to type-check code that uses outside modules, from the standard library or a third-party library, the tool needs to understand the types used in the public interfaces of the library. The type-checking that can be done is limited if there are no stubs for the libraries used.

Python 2.7 will reach its end of life in less than two years—at least for the core development team. Linux distributions need to figure out how to handle the transition given that many of their users are still using that version of the language—and may still be well beyond the end-of-life date. Petr Viktorin and Matthias Klose led a session at the 2018 Python Language Summit to discuss distributions' approaches to deprecating Python 2.
Viktorin works for Red Hat and focused on the Fedora distribution. He wants to help figure out how to help the Python downstreams so that Python 2 can be fully discontinued. There are two different ways to do that; either make sure that everyone switches to Python 3 or simply deprecate Python 2 and "wash our hands" of the problem. He would prefer the first alternative. He will be working on this transition for Red Hat as part of his day job and would like to do it in the community as well; that will minimize the need to maintain Python 2 going forward.
