  • Release notes for the Genode OS Framework 20.05

    Genode 20.05 takes our road map's focus on the consolidation and optimization of the framework and its API to heart. It contains countless of under-the-hood improvements, mostly on the account of vastly intensified automated testing, the confrontation of Genode with increasingly complex software stacks, and stressful real-world work loads. You will find this theme throughout the release notes below. The result of this overhaul is captured in the updated version of the Genode Foundations book (Section New revision of the Genode Foundations book).

    [...]

    Even though Genode is able to run on top of the Linux kernel since the very beginning, Linux was solely meant as a development vehicle.

  • Genode OS 20.05 Adds Capability-Based Security Using SECCOMP, Drops Python 2 + Rust

    Version 20.05 of the Genode open-source operating system framework is now available with many improvements.

    Genode OS 20.05 contains various work particularly on the consolidation and optimization front. There is also better 64-bit Arm support, documentation improvements, and capability-based security using SECCOMP on Linux.

    Genode OS 20.05 has improvements to its consistent block encrypter, retired its Noux runtime environment, removed Rust support after no one has been maintaining its support in years, dropping Python 2 given its EOL status and Python 3 support being in good shape, MSI-X support on x86, and various other updates.

  • COVID-19 Crisis: FOSS Responders Raises $115,000 To Support Community

    Conference cancellations have caused financial loss, unmet fundraising trajectories and missed business opportunities. For example, the Open Source Institute, the organisation that ratifies open source licences, has indicated that it needs $600,000 to meet its funding goals for 2020 while the Drupal Association has had to layoff employees after cancelling events and needs to fundraise $500,000.

  • It’s Time to Get Back Into RSS

    A lot of people who were on the internet in the early 2000’s remember something called RSS. It stands for really simple syndication, and it allowed content creators to publish updates to the world in a well-understood format.

    The idea—which seems strange to type out—is that millions of people in the world could create and publish ideas, thoughts, and content…and then people who enjoyed that content would collect sources into a reader, which was called, well, an RSS Reader.

    [...]

    But perhaps most devastating was the web’s move to an advertising model, which RSS runs directly counter to. With RSS you get the content itself, which your reader can choose to display in different ways. Advertisers hate that. They want you to see the original website so they can show you ads the way they want you to see them.

    I’m sure social media sites had an effect too, because—like aggregators—they were singular watering holes that guaranteed something exciting when you showed up. The common denominator is the move from more effort to less. It’s like in WALL-E, where we turn into morbidly obese people on hoverchairs being shuttled between stimuli.

    Regardless of the percentages, all those factors combined to destroy the model of getting raw content directly from the source.

    Well, it’s time to bring that back. It’s time to return to RSS.

    Google Reader is still dead, but if I remove my nostalgia glasses, feedly is probably better now than Reader ever was. It’s what I’ve been using for years now.

  • Building a successful open source community: How coordination and facilitation helps projects scale and mature

    We tend to think of the primary goals of the Linux Foundation’s projects as producing open software, open hardware, open standards, or open data artifacts — the domain of participating programmers & engineers, system architects, and other technical contributors.

    However, successful projects engaging a broader ecosystem of commercial organizations, particularly when raising funds, benefit from active leadership besides pure technical contributions. Contributors often have work outside the project that often puts demands on their time. It takes real time to build and coordinate a commercial ecosystem, ensure stakeholders are engaged, recruiting and onboarding members, create a neutral governance culture (often amid competitors competing), and to keep various aspects of the ecosystem aligned such as when end users begin to participate.

    Many Linux Foundation projects fundraise to provide resources for their community. This is an excellent benefit for the technical community when the business ecosystem comes together to invest and help the community obtain resources to build a thriving community and ecosystem. A typical fundraising model in our community is to offer an annual membership structure that provides a yearly fund for the project.

  • Oracle’s open-source alter ego behind some of its most popular products

    Open-source innovation may not be the words evoked by a legacy technology company such as Oracle, a company turning 43 years old next month. But the fact is that — like many companies — Oracle’s paid products and services are actually loaded with ingredients from open-source communities, including Linux, to which it is also a contributor.

    This circular ecosystem of contributing and borrowing back enables some of the versatility and cross-environment compatibility in the company’s latest database and hybrid-cloud offerings.

  • Christian Schaller: Into the world of Robo vacums and Robo mops

    So to conclude, would I recommend robot vacuums and robot mops to other parents with you kids? I would say yes, it has definitely helped us keep the house cleaner and nicer and let us spend less time cleaning the house. But it is not a miracle cure in any way or form, it still takes time and effort to prepare and set up the house and sometimes you still need to do especially the mopping yourself to get things really clean. As for the question of iRobot versus other brands I have no input as I haven’t really tested any other brands. iRobot is a local company so their vacuums are available in a lot of stores around me and I drive by their HQ on a regular basis, so that is the more or less random reason I ended up with their products as opposed to competing ones.

Making Zorin OS 15 Works With GLIM Multiboot USB

In late 2019 I successfully ship multiboot drives with Zorin OS as one among many operating systems within them. I have made the articles in making them multibootable most notably openSUSE, Deepin, and Slackware, as they were actually not supported by GLIM multiboot maker. However, I forgot that I have not made such article about Zorin as I thought I have. Now I remembered it in 2020 and this is the article you can learn once again to make it bootable like what I am currently doing with my latest Zorin articles. Enjoy! Read more

Python Programming

  • Find the coefficients of the Quadratic Equation of the given two roots with Python

    In this example, you are expected to find the coefficients of the quadratic equation of the given two roots (x1 and x2) with a python function. The Quadratic Equation looks like this ax^2 + bx + c = 0. Our mission is to find the coefficients of the equations which is a, b, and c. The return type from the function is a Vector containing coefficients of the equations in the order (a, b, c). Since there are infinitely many solutions to this problem, we fix a = 1. Below is the method to find the return Vector.

  • 10 most useful Python Dictionary Methods

    Dictionary is used in python to store multiple data with key-value pairs. It works like an associative array of other programming languages. The curly ({}) brackets are used to define a dictionary and the key-value is defined by the colon(:). The content of the key and value can be numeric or string. Python has many built-in methods to do different types of tasks on the dictionary data such as add, update, delete, search, count, etc. 10 most useful dictionary methods of python are explained in this article.

  • 10 most useful Python String Methods

    The string data is the characters of an array that contains one or more characters as value for any programming language. All printable characters such as alphabets, numbers, special characters, etc. are commonly used in the string data. ASCII code and Unicode are mainly used for converting any character to a number that the computer can understand. Python uses Unicode characters for string data. We need to perform different types of tasks based on the programming purpose on the string data such as searching the particular character or characters, capitalizing the first character, making all characters uppercase, etc. Python has many built-in string methods to do these types of tasks very easily. The 10 most useful python string methods are explained in this article.
