Best Computerized Telescopes for Linux

We are living in exciting times, don’t you think? Interstellar objects are visiting our galaxy. Astronomers are winning Nobel. History is being made in so many fields of Astronomy. Thanks to the advancements in computers and technology, today, anyone can indulge in amateur level astrophotography. You just need the right equipment, a few add-ons, and you are all set. However, before you set your eyes at the Saturns rings, Martian ice-caps, or Jupiter’s moons, you need to learn the basics of Computerized Telescopes. Worry not, if you don’t know what those are. We will be covering all that in the buyer’s guide section.

  • Purism: Our tips for remote working

    Most of us don’t like writing documentation at the best of times but when going remote, a great team wiki or docs portal can help keep everyone in the loop and reduce repetitive questioning in team chat. Choose a solution that tracks changes (version control) and if needed, has an easy to use interface for non-technical people. We use wiki.js backed by git. You should document something if you have to say it more than once. This will empower people to answer their own questions by searching for the answer. If you are looking for a good example of team documentation take a look at GitLab’s public handbook (our wiki is private).

  • Dirk Eddelbuettel: RQuantLib 0.4.12: Small QuantLib 1.18 update

    QuantLib is a very comprehensice free/open-source library for quantitative finance; RQuantLib connects it to the R environment and language. This version does relatively little. When QuantLib 1.18 came out, I immediately did my usual bit of packaging it for Debian as well creating binaries via my Ubuntu PPA so that I could test the package against it. And a few call from RQuantLib are now hitting interface functions marked as ‘deprecated’ leading to compiler nags. So I fixed that in PR #146. And today CRAN sent me email to please fix in the released version—so I rolled this up as 0.4.12. Not other changes.

  • Observing Coronavirus Pandemic with Raku

    Every few years a new unknown virus pops up and starts spreading around the globe. This year, the situation with COVID-19 is different not only because of the nature of the virus but also because of the Internet. Whilst we have instant access to new information (which is often alarmist in tone) we also have the ability to access data for ourselves. Johns Hopkins University Center for Systems Science and Engineering synthesizes COVID-19 data from different sources, and displays it on their online dashboard. They also publish daily updates in CSV files on GitHub. I decided to ingest their CSV data and display it using different visualizations to reduce panic and provide a way to quickly see real numbers and trends. The result is the website The source files are available in the GitHub repository.

  • Visualizing Decision Trees with Python (Scikit-learn, Graphviz, Matplotlib)

    Decision trees are a popular supervised learning method for a variety of reasons. Benefits of decision trees include that they can be used for both regression and classification, they don’t require feature scaling, and they are relatively easy to interpret as you can visualize decision trees. This is not only a powerful way to understand your model, but also to communicate how your model works. Consequently, it would help to know how to make a visualization based on your model.

  • Onboarding Continuity - Building SaaS #50

    In this episode, we stepped from the welcome onboarding page to the first interactive page in the flow. I extracted the common banner for each of the templates and customized it for each of the steps in the process. The first thing we did was create a button on the starting page. The button connects the welcome page to the second step in the flow where the app will ask for information about the user’s school year. With the button in place, we created the new view to handle the school year form. Before getting into that form, I extracted the common onboarding banner into a template fragment.
