    A dataset I recently audited contained multiple UTF-8 encodings of the same characters. For example, the dataset contained three different °, three different ' and three different ".

  • Learn Python programming the easy way with EduBlocks

    If you are you looking for a way to move your students (or yourself) from programming in Scratch to learning Python, I recommend you look into EduBlocks. It brings a familiar drag-and-drop graphical user interface (GUI) to Python 3 programming.

    One of the barriers when transitioning from Scratch to Python is the absence of the drag-and-drop GUI that has made Scratch the go-to application in K-12 schools. EduBlocks' drag-and-drop version of Python 3 changes that paradigm. It aims to "help teachers to introduce text-based programming languages, like Python, to children at an earlier age."

    The hardware requirements for EduBlocks are quite modest—a Raspberry Pi and an internet connection—and should be available in many classrooms.

    EduBlocks was developed by Joshua Lowe, a 14-year-old Python developer from the United Kingdom. I saw Joshua demonstrate his project at PyCon 2018 in May 2018.

The Ubuntu Server edition is also out and it's supported on more hardware architectures than Ubuntu Desktop, including 64-bit (amd64), ARM64 (AArch64), IBM System z (s390x), PPC64el (Power PC 64-bit Little Endian), and Raspberry Pi 2/ARMhf. A live Ubuntu Server flavor is also available only for 64-bit computers. Read more Also: Ubuntu Linux 18.10 arrives

Single-board computer guide updated: Free software is winning on ARM!

In many geeky circles, single-board computers are popular machines. SBCs come in small form factors and generally run GNU/Linux, but unfortunately, many boards like the popular Raspberry Pi are dependent on proprietary software to use. The Free Software Foundation maintains a list of system-on-chip families, sorted by their freedom status. Unfortunately, this list had not been updated in several years. While it was accurate when it was published, free software is constantly improving. Today, more and more boards are usable with free software. On the graphical side, the Etnaviv project has reached maturity, and the Panfrost project, with which I have been personally involved, has sprung up. The video processing unit on Allwinner chips has been reverse-engineered and liberated by the linux-sunxi community in tandem with Bootlin. Rockchip boards have become viable competitors to their better known counterparts. Even the Raspberry Pi has had a proof-of-concept free firmware replacement developed. Free software is winning on ARM. Read more
