Getting started with FreeBSD as a desktop operating system

ven, 05/08/2020 - 09:02

FreeBSD is a great operating system, but, by design, it does not come with a desktop environment. Without installing additional software from FreeBSD's ports and packages collection, FreeBSD is a command-line only experience. The screenshot below shows what logging into FreeBSD 12.1 looks like when every one of the "optional system components" is selected during installation.

In the first two articles in this series, I explored the Linux systemd startup sequence. In the first article, I looked at systemd's functions and architecture and the controversy around its role as a replacement for the old SystemV init program and startup scripts. And in the second article, I examined two important systemd tools, systemctl and journalctl, and explained how to switch from one target to another and to change the default target.

6 open source alternatives to Wunderlist

mer, 05/06/2020 - 09:03

Wunderlist is an app for lists, loved by many, but gone for good as of May 6, 2020. The website encourages existing users to download and use Microsoft To Do in its place. That's tempting because it makes it easy to import all of those lists you've made over the years. Then again, maybe it's a chance to Marie Kondo those lists and pare things down. Do you really need 30 lists? (Apparently, I've decided that I do, so I won't judge.)

Managing Git projects with submodules and subtrees

mer, 05/06/2020 - 09:00

If you are into open source development, you have probably worked with Git to manage source code. You might have come across projects with numerous dependencies and/or sub-projects. How do you manage them?

For an open source organization, it can be tricky to achieve single-source documentation and dependency management for the community and the product. The documentation and project often end up fragmented and redundant, which makes them difficult to maintain.

Understanding systemd at startup on Linux

lun, 05/04/2020 - 09:03

In Learning to love systemd, the first article in this series, I looked at systemd's functions and architecture and the controversy around its role as a replacement for the old SystemV init program and startup scripts.

Use this Python script to encode binary in Base94

lun, 05/04/2020 - 09:02

Humans transfer information in many different ways. On the internet, the primary format is text, which is how you're reading this article. However, there is other data on the internet, such as images and sound files and so on. It might seem easy to post an image online or attach a document to an email, until you realize that HTTP/1.1 and SMTP are text-based protocols. Data transferred over such protocols must be represented as a subset of ASCII text (specifically, characters 33 to 126).

The real impact of canceling PyCon due to COVID-19

sam, 05/02/2020 - 09:01

The Python Software Foundation (PSF) had to cancel its popular PyCon US event in response to COVID-19. I interviewed Ewa Jodlowska, Executive Director of the PSF, to talk about the experience and see what we all can learn, and how we can be supportive of the non-profit that supports one of my favorite programming languages.
