Use a Linux terminal on your Android phone

When it comes to ultra-mobile computing, I prefer the PocketCHIP or a Raspberry Pi with a screen rather than a mobile phone or tablet. These solutions offer a pure Linux environment that's as open source as the hardware allows and make no assumptions about how I expect to work. Sometimes, though, the only thing I have on me is a mobile phone. While there are some really great Android apps out there, many feel like overkill for simple tasks, especially knowing how much can be done in a simple terminal on my Linux desktop. I'm not the only person who feels this way, and that's why the Termux project was born.

5 Best SSH and FTP Android Apps for Linux

My most recent coverage on remote sessions was on takeover.sh, an open-source script for operating Linux using SSH. Today’s eye is on the best apps that enable us to operate Linux from any modern Android device. All these applications are loved for their speed, low memory requirement, price tag, and ease of use. Do you have any suggestions that should be on the list? Add your comments below.

• GNU Emacs 27.1 Adds HarfBuzz Text Shaping, Native JSON Parsing

  GNU Emacs 27.1 is the latest feature release for this very extensible text editor. With Emacs 27.1 there is support for utilizing the HarfBuzz library for text shaping. HarfBuzz is also what's already used extensively by GNOME, KDE, Android, LibreOffice, and many other open-source applications. Emacs 27.1 also adds built-in support for arbitrary-size integers, native support for JSON parsing, better support for Cairo drawing, support for XDG conventions for init files, the lexical binding is now used by default, built-in support for tab bar and tab-line, and support for resizing/rotating images without ImageMagick, among other changes.

• Philip Withnall: Controlling safety vs speed when writing files

  g_file_set_contents() has worked fine for many years (and will continue to do so). However, it doesn’t provide much flexibility. When writing a file out on Linux there are various ways to do it, some slower but safer — and some faster, but less safe, in the sense that if your program or the system crashes part-way through writing the file, the file might be left in an indeterminate state. It might be garbled, missing, empty, or contain only the old contents. g_file_set_contents() chose a fairly safe (but not the fastest) approach to writing out files: write the new contents to a temporary file, fsync() it, and then atomically rename() the temporary file over the top of the old file. This approach means that other processes only ever see the old file contents or the new file contents (but not the partially-written new file contents); and it means that if there’s a crash, either the old file will exist or the new file will exist. However, it doesn’t guarantee that the new file will be safely stored on disk by the time g_file_set_contents() returns. It also has fewer guarantees if the old file didn’t exist (i.e. if the file is being written out for the first time).

• Daniel Espinosa: Training Maintainers

  Is not just help others to help you, is a matter of responsibility with Open Source Community. Your life have wonders and should change for better, so you will be lost opportunities or simple can’t work on your favorite open source project. Prepare your self to be a maintainer professor, change your mind for the beginning and help others, that is also a great contribution to open source software. Be kind. Your potential contributors will take over when required. Making sure they have the abilities and use best practices in the project, is not just good for your project, is good for all others out there; they will use them to help other projects.

• nanotime 0.3.1: Misc Build Fixes for Yuge New Features!

  The nanotime 0.3.0 release four days ago was so exciting that we decided to do it again! Kidding aside, and fairly extensive tests notwithstanding we were bitten by a few build errors: who knew clang on macOS needed extra curlies to be happy, another manifestation of Solaris having no idea what a timezone setting “America/New_York” is, plus some extra pickyness from the SAN tests and whatnot. So Leonardo and I gave it some extra care over the weekend, uploaded it late yesterday and here we are with 0.3.1. Thanks again to CRAN for prompt processing even though they are clearly deluged shortly before their (brief) summer break.

• Explore 10 popular open source development tools

  There is no shortage of closed-source development tools on the market, and most of them work quite well. However, developers who opt for open source tools stand to gain a number of benefits. In this piece, we'll take a quick look at the specific benefits of open source development tools, and then examine 10 of today's most popular tooling options. [...] Git is a distributed code management and version-control system, often used with web-based code management platforms like GitHub and GitLab. The integration with these platforms makes it easy for teams to contribute and collaborate, however getting the most out of Git will require some kind of third-party platform. Some claim, however, that Git support for Windows is not as robust as it is for Linux, which is potentially a turnoff for Windows-centric developers. [...] NetBeans is a Java-based IDE similar to Eclipse, and also supports development in a wide range of programming languages. However, NetBeans focuses on providing functionality out of the box, whereas Eclipse leans heavily on its plugin ecosystem to help developers set up needed features.

• Andre Roberge: Rich + Friendly-traceback: first look

  After a couple of hours of work, I have been able to use Rich to add colour to Friendly-traceback. Rich is a fantastic project, which has already gotten a fair bit of attention and deserves even more. The following is just a preview of things to come; it is just a quick proof of concept.

• Growing Dask To Make Scaling Python Data Science Easier At Coiled

  Python is a leading choice for data science due to the immense number of libraries and frameworks readily available to support it, but it is still difficult to scale. Dask is a framework designed to transparently run your data analysis across multiple CPU cores and multiple servers. Using Dask lifts a limitation for scaling your analytical workloads, but brings with it the complexity of server administration, deployment, and security. In this episode Matthew Rocklin and Hugo Bowne-Anderson discuss their recently formed company Coiled and how they are working to make use and maintenance of Dask in production. The share the goals for the business, their approach to building a profitable company based on open source, and the difficulties they face while growing a new team during a global pandemic.
