Open Hardware: Raspberry Pi and Trace Together (Singapore) Token

  • Customize your Raspberry Pi operating system for everyday use

    If you have a Raspberry Pi running Raspberry Pi OS (previously known as Raspbian) operating system, you know it's an awesome little computer with a great operating system for beginners that includes just about everything you could possibly want. However, once you become familiar with the Pi and want to start using it for other things, you might want an operating system (OS) that doesn't include everything in the default build.

    When that happens, you have two choices: You can pull your hair out trying to uninstall all the cruft you don't want, or you can use Raspberry Pi OS Lite to build your own custom, lightweight operating system tailored to your exact specs. I suggest saving yourself some time and aggravation and going with the latter option.

  • New product Monday: pi3hat

    This board breaks out 4x 5Mbps CAN-FD ports, 1 low speed CAN port, a 1kHz IMU and a port for a nrf24l01. Despite its name, it works just fine with the Rasbperry Pi 4 in addition to the 3b+ I have tested with mostly to date. I also have a new user-space library for interfacing with it that I will document in some upcoming posts. That library makes it pretty easy to use in a variety of applications.

  • Trace Together Token: Teardown and Design Overview

    On 19 June, GovTech Singapore invited four members of the community to come and inspect their new TraceTogether Token. This token removes the need to carry a phone at all times, and is designed to help both those who do not have a smart device capable of running TraceTogether well, including those using older Android devices, non-smartphones, and iOS users. I was among the group, which also consisted of Roland Turner, Harish Pillay, and Andrew "bunnie" Huang, who were given the opportunity to see the first public revision of hardware. In this post I will discuss the goal of the token, give some overview of the hardware, compare it with the app version of TraceTogether, and comment on the protocol changes.

  • A Quick Look At Slackel 7.3 Openbox

    Slackel is a Linux distribution based on Slackware and Salix. It is fully compatible with Slackware but the difference is that it is based on the development branch. Slackel comes in three editions, KDE, Openbox and MATE. Today, I'm taking a look at the recently released Slackel 7.3 Openbox. 

  • Council policy proposal: Process for promoting Fedora deliverable to Edition

    With several Fedora deliverables ready (or nearly ready) to be promoted to Edition status, we need a policy for how this will work. After consulting with representatives from QA, Release Engineering, and Fedora IoT, I drafted a proposed process. The Council will begin voting on Tuesday 28 July in accordance with the policy change policy.

  • Storage solution and engaged partnership between Fujitsu and SUSE

    Fujitsu and SUSE have been partners for many years, and we are strategically collaborating on the needs and issues of customers in enterprise environments such as SUSE Business Critical Linux. At the online event SUSECON digital started from May 20, Fujitsu Keynote session will explain the solution development of both companies to the future market. At last year’s SUSECON, a technical session was conducted based on verification information on how to achieve system update and non-disruptive data migration to SUSE Enterprise Storage without stopping service and user access by Fujitsu and SUSE for existing Ceph environment. Please don’t miss Fujitsu Data Driven transformation sessions at SUSECON digital this year.

  • Updating Documentation for openSUSE Leap 15.2

    After having a Virtual Live Installation Party on YouTube yesterday (02 Jul 2020). I realized, I have to test and update documentation out there on my site as well as the openSUSE Wiki. This is one of those things that I do as I have time, generally. Essentially, this is what I have done for the last several years, not 100% consistently but generally speaking, I keep on top of it. In order to stay organized, I have a “personal” wiki page that I keep track of what it is that I maintain. [...] If you are using a “free” operating system, it isn’t free. It has taken work and love to make it possible for you to use it. People are making personal sacrifices, often without pay, to bring this wonderful tool for you to use. Find a way to contribute back, in whatever way is within your abilities and pay the good will forward. [...] I openly admit my almost unhealthy obsession for the openSUSE project, it is in my obsession that I feel compelled to contribute where ever I can. I am forever thankful for everyone that takes the time to make openSUSE, Linux and all the software that I use possible. The freedom and ability to use my computer that suits my requirements best is something for which I am continually grateful.

  • CMake-Based Qt Creator Snapshots

    About a year ago we started porting the build system that we use for building Qt Creator itself from qmake to CMake. Nowadays we are in the state that many Qt Creator developers use CMake for building Qt Creator for their daily work, but the official packages are still based on the qmake build.

  • Week #6 Progress [MyPaint Engine]

    Last week my prime focus was to add more and more settings in the preset editor and so as to make mypaint brushes a bit more customizable. I used KisCurveOptionWidget class which Krita already has and modified it so that it can accomodate the settings and dynamic mypaint brush options. This went on to become a lot more complicated than I anticipated. Although, it works fine there are still a lot of bugs and finishing required to mark this as complete.

  • Stack Abuse: What's New in Tensorflow 2.0?

    If you are a Machine Learning Engineer, Data Scientist, or a hobbyist developing Machine Learning Models from time to time just for fun, then it is very likely that you are familiar with Tensorflow. Tensorflow is an open-source and a free framework developed by Google Brain Team written in Python, C++, and CUDA. It is used to develop, test, and deploy Machine Learning models. Initially, Tensoflow did not have full support for multiple platforms and programming languages, and it was not very fast and efficient for training Machine Learning models, but with time and after a few updates, Tensorflow is now considered as a go-to framework for developing, training and deploying machine learning models.
