How do you ensure the stability of your Kubernetes (K8s) clusters? How do you know that your manifests are syntactically valid? Are you sure you don't have any invalid data types?

Enter invisible passwords using this Python module

Tuesday 6th of July 2021 01:07:42 AM
Passwords are particularly problematic for programmers. You're not supposed to store them without encrypting them, and you're not supposed to reveal what's been typed when your user enters one. This became particularly important to me when I decided I wanted to boost security on my laptop. I encrypt my home directory—but once I log in, any password stored as plain text in a configuration file is potentially exposed to prying more

Raspberry Pi 4 2GB jumps to $45 as 1GB model returns from the dead at $35

Citing chip shortages, Raspberry Pi announced its first price increase, bumping the RPi 4 with 2GB RAM up to $45. Meanwhile, the discontinued RPi 4 1GB has come back to life at $35. In the spirit of Halloween, Raspberry Pi Trading has reanimated the 1GB RAM version of the Raspberry Pi 4 Model B, which it killed off when it dropped the price of the 2GB model from $45 to $35 in Feb. 2020. The company also increased the 2GB price to $45. With the 1GB version returning at its old $35 price, we have essentially turned back the clock to early 2020. (In which case, maybe we could get a second chance on stopping the pandemic.) In the Raspberry Pi blog post announcing the changes, CEO Eben Upton cited industry-wide supply chain issues for its first price increase in Pi history. The chip shortages, combined with heightened demand, have caused severe shortages of the RPi Zero and the RPi4 2GB. Read more

The love/hate relationship the cloud has with Linux

The cloud is run by Linux and open-source. There is no debating that claim at this point. It's fact. And not only does Linux power all of those cloud services we deploy and use, but the hold it has over that particular tech sector is also only going to get stronger as we march into the future. I predict that, over the next five years, the cloud and Linux will become synonymous to the point everyone (from CEOs to end-users) will finally get just how important and powerful the platform is. So it's safe to say, there would be no cloud without Linux. There would also be no cloud-native development, Kubernetes, Docker, virtual machines or containers in general. With that in mind, it should stand to reason that the relationship between Linux and the cloud would be all love. Read more

You Can Now Install the UnityX Desktop in Arch Linux, Here's How

UnityX is the successor of the Unity7 desktop environment created by Canonical for its popular Ubuntu Linux distribution back in 2011 with the Ubuntu 11.04 release.

In May 2020, developer Rudra Saraswat created an unofficial Ubuntu flavor called Ubuntu Unity, which features the good old Unity7 desktop environment. Now, the Ubuntu Unity creator wants to take Unity7 to the next level and created UnityX, a modern, yet simple desktop environment. Read more

PSA: gnome-settings-daemon's MediaKeys API is going away

In 2007, Jan Arne Petersen added a D-Bus API to what was still pretty much an import into gnome-control-center of the "acme" utility I wrote to have all the keys on my iBook working. It switched the code away from remapping keyboard keys to "XF86Audio*", to expecting players to contact the D-Bus daemon and ask to be forwarded key events. In 2013, we added support for controlling media players using MPRIS, as another interface. Fast-forward to 2021, and MPRIS support is ubiquitous, whether in free software, proprietary applications or even browsers. So we'll be parting with the "org.gnome.SettingsDaemon.MediaKeys" D-Bus API. If your application still wants to work with older versions of GNOME, it is recommended to at least quiet the MediaKeys API's unavailability. Read more
