snekde — an IDE for snek development
I had hoped to create a stand-alone development environment on the Arduino, but I've run out of room. The current snek image uses 32606 bytes of flash (out of 32768) and 1980 bytes of RAM (out of 2048). I can probably squeeze a few more bytes out, but making enough room for a text editor seems like a stretch.
As a back-up plan, I've written a host-side application that communicates with the Arduino over the serial port.

Introducing the Small Scale Scrum framework
Scrum is a leading candidate for the implementation of Small Scale Agile for many reasons, including its popularity, developers’ preferences, high success rates for scrum adoption and project deliveries, and strong principles and values including focus, courage, openness, commitment, and respect.
Small Scale Scrum can be best described as “a people-first framework defined by and for small teams (a maximum of three people) and supporting planning, developing, and delivering production-quality software solutions.” The proposed framework centers around the concept of team members occupying multiple roles on any project.
Small Scale Scrum is valuable due to its strong support for the small, distributed teams found in organizations all over the world. Small teams need new ways to meet customers’ continuously growing expectations for rapid delivery and high quality, and Small Scale Scrum’s guidelines and principles help address this challenge.

GCC 8/9 vs. LLVM Clang 7/8 Compiler Performance On AArch64
With Clang 8.0 due out by month's end and GCC 9 due for release not long after that point, this week we've been running a number of GCC and Clang compiler benchmarks on Phoronix. At the start of the month was the large Linux x86_64 GCC vs. Clang compiler benchmarks on twelve different Intel/AMD systems while last week was also a look at the POWER9 compiler performance on the Raptor Talos II. In this article we are checking out these open-source compilers' performance on 64-bit ARM (AArch64) using an Ampere eMAG 32-core server.

How Clear Linux Optimizes Python For Greater Performance
Clear Linux's leading performance isn't limited to just C/C++ applications but also scripting languages like PHP, R, and Python have seen great speed-ups too. In a new blog post, one of Intel's developers outlines some of their performance tweaks to Python for delivering greater performance.
Last April, Victor Rodriguez Bahena of the Intel Open-Source Technology Center and longtime Clear Linux developer began shedding more light on their "magic" performance work for the distribution's out-of-the-box performance. Finally this week the second post in that series is out as he details the optimizations made to their Python implementation.

Qt 5.13 Alpha Released
I am happy to inform that Qt 5.13 Alpha is released today. You can download Qt 5.13 Alpha via online installer (both source and prebuild binary packages). Source packages are also available for commercial users in the Qt Account portal and in the download.qt.io for open-source users.
Qt 5.13 New Features page contains information about most important changes coming with the release. Please remember creating the list is still in progress so something important can still be missing. List should be completed by Beta1.
Target is to release Beta1 within coming weeks, when API reviews are concluded. And as with previous releases we will release regular beta n releases until we are ready for RC. Target for Beta1 is 26.2.2019, see whole schedule from Qt 5.13 wiki.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
