Journal five minutes a day with Jupyter

Ceramic mug of tea or coffee with flowers and a book in front of a window
Some people follow the tradition of creating New Year's resolutions. A year is a long time, though, so I plan with a seasonal theme or trajectory. Each quarter, I sit down and look at the upcoming three-month season and decide what I'll work on during that time.

For my latest theme, I decided I wanted to write a daily journal. I like having clear commitments, so I committed to writing for five minutes each day. I also like having observable commitments, even if it is just for me, so I put my entries in Git.

Try Jed as your Linux terminal text editor

Person using a laptop
You may have heard about Emacs and Vim and Nano, the quintessential Linux text editors, but Linux has an abundance of open source text editors, and it's my goal to spend December giving 31 of them a fair go.

In this article, I look at Jed, a terminal-based editor featuring a handy drop-down menu, which makes it especially easy for users who are new to terminal editors, as well as those who just don't like remembering keyboard combinations for every function.

In the year since the Raspberry Pi 4 was released, I've seen many tutorials (like this and this) and articles on how well the 4GB model works with container platforms such as Kubernetes (K8s), Lightweight Kubernetes (K3s), and Docker Swarm. As I was doing research, I read that Arm processors are "first-class citizens" in OpenStack.

An Open Letter to President-elect Biden

Dear Mr. President-elect,

First, I’d like to offer my sincere congratulations to you and to Vice President-elect Kamala Harris. This has been such a difficult year for so many around the world, and in this time of extreme polarization it is encouraging to hear you both talk about bringing people together to meet our common challenges. For many years I was a Member of the European Parliament, and I know how incredibly important it is to build bridges and work collaboratively with people we don’t always agree with.

I’m writing today as the leader of Creative Commons, a global nonprofit organization focused in part on making valuable scientific research and educational resources freely and openly available to the public. We work with universities, companies, governments, and institutions around the world to develop solutions for providing unencumbered access to knowledge.

In your 2016 speech to the American Association for Cancer Research, you quoted an article written by our then-CEO, Ryan Merkley, about the unnecessary barriers to publicly funded research. You noted that “taxpayers fund billion in cancer research every year, but once it’s published, nearly all of [it]sits behind walls.” You correctly suggested that better treatments might be developed more quickly if cancer researchers, as well as the general public, had access to the rich trove of publicly funded research and data that is locked up behind prohibitive paywalls.

The COVID-19 health crisis has underscored the urgent need for scientific research and data to be shared freely and openly with others. Several of the most significant funders of scientific research, including the National Institutes of Health, the Gates Foundation, and the Wellcome Trust have long-standing open access policies. But many others do not, and as a result, many of the diagnostics, vaccines, therapeutics, medical equipment, and software solutions currently being developed in the fight against the pandemic will not reach and benefit as many people as quickly and effectively as they should.

Additionally, as you are very well aware, the pandemic has massively disrupted the lives of over a billion students around the world. For many, access to educational materials is a daily struggle even in normal times. Because of a myriad of barriers, such as the prohibitive cost of learning resources, or the legal maze of convoluted copyright rules and exceptions, many students are denied their fundamental human right to education.

This year’s shift to online learning has introduced many new complexities for both students and educators. While some educators can post their existing learning materials online for their students, for others, the move to online requires access to, and the legal rights to perpetually use and adapt materials developed by others. This has brought into focus the essential need for both broad access to Open Educational Resources (OER) and broad copyright limitations and exceptions (L&E) for educators and students to freely and legally use copyright works so all students everywhere can learn.

At Creative Commons, we believe that open access to knowledge is critical—especially during times of crisis. For nearly 20 years, we have collaborated closely with entities including the US government to make the world more equitable by overcoming obstacles to the sharing of knowledge. In these unprecedented times, our mission is more important than ever, and I look forward to working with you and your administration in developing solutions that unlock knowledge and make it possible for anyone, anywhere to access and build upon it.

Catherine Stihler
CEO, Creative Commons

Create a machine learning model with Bash

bash logo on green background
Machine learning is a powerful computing capability for predicting or forecasting things that conventional algorithms find challenging. The machine learning journey begins with collecting and preparing data—a lot of it—then it builds mathematical models based on that data. While multiple tools can be used for these tasks, I like to use the shell.

Lord of Misrule: Thomas Morton’s American Subversions

When we think of early New England, we tend to picture stern-faced Puritans and black-hatted Pilgrims, but in the same decade that these more famous settlers arrived, a man called Thomas Morton founded a very different kind of colony — a neo-pagan experiment he named Merrymount. Ed Simon explores the colony’s brief existence and the alternate vision of America it represents.

Got something to say? How to get started writing

A person writing.
Well, I suppose after all this talk of how to find your story and then write your story, I should make a post about how to do just that. I've broken it down into three sections: how to find your story, how to write your story, and how to share it and get it published.

During the All Things Open virtual event this year, I was invited to share my tips, and now you can watch that. It's about 20 minutes with some questions and commentary at the end.

Get started with Fossil, an alternative to Git

Dinosaurs on land at sunset
As any programmer knows, there are many reasons it's vital to keep track of code changes. Sometimes you just want a history of how your project started and evolved, as a matter of curiosity or education. Other times, you want to enable other coders to contribute to your project, and you need a reliable way to merge disparate parts. And more critically, sometimes an adjustment you make to fix one problem breaks something else that was working.

The Wizard and the Djinn

Image by OpenClipart-Vectors from Pixabay

The Wizard and the Djinn
by Larry Heyl CC BY


The party wakes up in the morning next to a clear running creek. There is a slight chill in the air so they stir up the fire and make hot tea. They eat fruit and biscuits with their tea as they trade stories around the fire.

(DM hint: time permitting go around the table with the stories allowing the PCs to fill in their backstory and add items to their character sheet.)

They hear a noise in the woods and they all look to see what it is. When they look back there is a striking figure wearing a pointed hat and holding a staff standing next to the fire. The wizard addresses the party saying “I’m Randolph the Red and I need your help with a quest. There is a famous Djinn, Coriandor, who has disappeared. He had a spell book I need called The Pink Omnibus. He also had gold and jewels. I don’t need the treasure, you can keep that. But I need the spell book and if we find his lamp I want that too. Grab your packs and fill your water bags. You’ll need water where we’re going.”

If party members do not do as told Randolph the Red puts a compulsion on them. They do get a saving throw but he is a very powerful wizard. When they all have their water the wizard steps into the middle of the party and slams his staff on the ground. They begin spinning in a large circle like they were caught up by a tornado and then they fall from the sky to land in a desert surrounded by sand vipers, no wizard in sight.


Recover the Pink Omnibus and the lamp.
Make off with the loot.
Somehow return home (Probably with Randolph the Reds help)
Get Even with Randolph the Red for his compulsion.

GitHub reinstates youtube-dl library after EFF intervention

GitHub also establishes a author='Blog – MixRemix' profile='' avatar='' guid='4f74e1faea2f31080dd343095b26a50e68249cd7' posted='2020-11-17 00:06:21' link='' million “developer defense fund” to help open source developers fight against abusive DMCA Section 1201 takedown claims.
But in a blog post today, GitHub said the library did not actually break Section 1201 of the DMCA, citing a letter it received from Electronic Frontier Foundation lawyers, who to take up the youtube-dl project’s case.

In the letter, the EFF team explained that Google does not have any technical measures in place to prevent the download of its videos — all of which need to be made freely available to all kinds of apps, browsers, smart TVs, and more.

Hence, EFF lawyers argued that the library could never be taken down under Section 1201 of the DMCA since the library doesn’t actually circumvent any sort of copyright protection system in the first place.
