4 open source Android apps for writers

mer, 06/26/2019 - 09:01

While I'm of two minds when it comes to smartphones and tablets, I have to admit they can be useful. Not just for keeping in touch with people or using the web but also to do some work when I'm away from my computer.

For me, that work is writing—articles, blog posts, essays for my weekly letter, e-book chapters, and more. I've tried many (probably too many!) writing apps for Android over the years. Some of them were good. Others fell flat.

How a trip to China inspired Endless OS and teaching kids to hack

mer, 06/26/2019 - 09:00

Last year, I decided to try out Endless OS, a lightweight, Linux-based operating system developed to power inexpensive computers for developing markets. I wrote about installing and setting it up. Endless OS is unique because it uses a read-only root file system managed by OSTree and Flatpak, but the Endless company is unique for its approach to education.

5 tiny Linux distros to try before you die

mar, 06/25/2019 - 09:01

There are plenty of Linux distributions out there to choose from when you're deciding what to run on a daily basis, yet some are so small that they get little notice. But tiny Linux distributions are powerful innovations: having an entire operating system drive a computer with less than 1GB of storage and half as much RAM is the ultimate software hack.

Tiny distros have many uses, such as:

The innovation delusion

mar, 06/25/2019 - 09:00

If traditional planning is dead, then why do so many organizations still invest in planning techniques optimized for the Industrial Revolution?

One reason might be that we trick ourselves into thinking innovation is the kind of thing we can accomplish with a structured, linear process. When we do this, I think we're confusing our stories about innovation with the process of innovation itself—and the two are very different.

Check your password security with Have I Been Pwned? and pass

lun, 06/24/2019 - 09:01

Password security involves a broad set of practices, and not all of them are appropriate or possible for everyone. Therefore, the best strategy is to develop a threat model by thinking through your most significant risks—who and what you are protecting against—then model your security approach on the activities that are most effective against those specific threats. The Electronic Frontier Foundation (EFF) has a great series on threat modeling that I encourage everyone to read.

7 infrastructure performance and scaling tools you should be using

ven, 06/21/2019 - 09:01

Sysadmins, site reliability engineers (SREs), and cloud operators all too often struggle to feel confident in their infrastructure as it scales up. Also too often, they think the only way to solve their challenges is to write a tool for in-house use. Fortunately, there are options. There are many open source tools available to test an infrastructure's performance. Here are my favorites.

The state of open source translation tools for contributors to your project

ven, 06/21/2019 - 09:00

In the world of free software, many people speak English: It is the one language. English helps us cross borders to meet others. However, this language is also a barrier for the majority of people.

Some master it while others don't. Complex English terms are, in general, a barrier to the understanding and propagation of knowledge. Whenever you use an uncommon English word, ask yourself about your real mastery of what you are explaining, and the unintentional barriers you build in the process.

How to SSH into a running container

jeu, 06/20/2019 - 09:03

Containers have shifted the way we think about virtualization. You may remember the days (or you may still be living them) when a virtual machine was the full stack, from virtualized BIOS, operating system, and kernel up to each virtualized network interface controller (NIC). You logged into the virtual box just as you would your own workstation. It was a very direct and simple analogy.

A beginner's guide to Linux permissions

mar, 06/18/2019 - 09:01

One of the main benefits of Linux systems is that they are known to be less prone to security vulnerabilities and exploits than other systems. Linux definitely gives users more flexibility and granular controls over its file systems' security permissions. This may imply that it's critical for Linux users to understand security permissions. That isn't necessarily true, but it's still wise for beginning users to understand the basics of Linux permissions.
