How an open project's governance model evolves

jeu, 07/02/2020 - 09:00

As we continue renovating the Open Organization community, we've been asking hard questions about how we want that community to function. What do we expect of one another, and of the new contributors yet to join us? How will we work best together? And how will we keep one another accountable for achieving our shared goals?

Install a Kubernetes load balancer on your Raspberry Pi homelab with MetalLB

mer, 07/01/2020 - 09:02

Kubernetes is designed to integrate with major cloud providers' load balancers to provide public IP addresses and direct traffic into a cluster. Some professional network equipment manufacturers also offer controllers to integrate their physical load-balancing products into Kubernetes installations in private data centers. For an enthusiast running a Kubernetes cluster at home, however, neither of these solutions is very helpful.

Back up your phone's storage with this Linux utility

mer, 07/01/2020 - 09:01

One of the great failings of mobile devices is how difficult it can be to transfer data from your device to your computer. Mobile devices have a long history of this. Early mobiles, like Pilot and Handspring PDA devices, required special synchronization software (which you had to do religiously for fear of your device running out of batteries and losing all of your data forever). Old iPods required a platform-specific interface. Modern mobile devices default to sending your data to an online account so you can download it again on your computer.

Read and write data from anywhere with redirection in the Linux terminal

mar, 06/30/2020 - 09:02

Redirection of input and output is a natural function of any programming or scripting language. Technically, it happens inherently whenever you interact with a computer. Input gets read from stdin (standard input, usually your keyboard or mouse), output goes to stdout (standard output, a text or data stream), and errors get sent to stderr.

Using Bash traps in your scripts

lun, 06/29/2020 - 09:02

It's easy to detect when a shell script starts, but it's not always easy to know when it stops. A script might end normally, just as its author intends it to end, but it could also fail due to an unexpected fatal error. Sometimes it's beneficial to preserve the remnants of whatever was in progress when a script failed, and other times it's inconvenient. Either way, detecting the end of a script and reacting to it in some pre-calculated manner is why the Bash trap directive exists.

A minimalist Mac terminal for Linux fans

lun, 06/29/2020 - 09:01

I have a confession to make: I have been a Mac user for more than 10 years now. At first, I felt a little shame, given my strong Linux background, but the Mac gives me a Unix-like shell and a great window manager. Because of that history, I have a mix of features that will run on macOS but feel familiar to Linux users. There's no reason it can't port over to Linux (and it has!).

An open source browser extension to zoom in on images

sam, 06/27/2020 - 09:00

Have you ever visited a website and wanted to see the images displayed larger? That happens to me all the time, and it isn't always easy to make that happen.

On occasion, I sift through the source code, use Ctrl + F to search for the image, copy the image source address and paste it into a new window in order to see the image at its full-size glory. Or, the other option is to right-click, copy the image address, and paste into a new tab.

Open source tools for translating British to American English

ven, 06/26/2020 - 09:01

Last Christmas, my wife and I traveled to my hometown of Ft. Pierce, Florida, and frequented a local establishment on the beach. There, we met a couple from The Midlands in the UK. The music was loud and so was the beer, so it was a bit hard to hear. Plus, even though it "seemed" they were speaking English, it was sometimes a challenge to understand what they were saying. I thought my time in Australia would have given me enough linguistic power, but, alas, a lot went over my head. There was more than the usual "soccer is football" or "trunk is a boot" sort of confusion.

5 modern alternatives to essential Linux command-line tools

jeu, 06/25/2020 - 09:03

In our daily use of Linux/Unix systems, we use many command-line tools to complete our work and to understand and manage our systems—tools like du to monitor disk utilization and top to show system resources. Some of these tools have existed for a long time. For example, top was first released in 1984, while du's first release dates to 1971.

Over the years, these tools have been modernized and ported to different systems, but, in general, they still follow their original idea, look, and feel.
