• How to build stronger teams in 2022: 10 must-read books | The Enterprisers Project

  The pandemic tested IT teams in entirely new ways and shed new light on the importance of taking care of employees’ very human needs in a difficult time. As former Best Buy CEO Hubert Joly recently wrote for the Harvard Business Review, that attention will shift to higher level needs like clarity, truth, connection, and growth. Leading and managing teams may take more nuance in this remade work environment, so we’re recommending ten books to help you build stronger teams for the days ahead, from better understanding (and even celebrating) the very human nature of teams to fostering high-performing teams in distributed environments to making the shift from team member to leader.

• When the open source ecosystem thrives in the cloud: IT leader insights

  Software is eating the world and open source has become the default way to build software. Public cloud has accelerated the proliferation of open source technologies, and has led to an adjustment in both the enterprise procurement and monetization of software. After a few years of seismic realignment (the aftershocks are still reverberating through the ecosystem), we have reached a point where there are paths for software vendors to partner with or live in the marketplaces of the hyperscalers, says Jerry Chen, a venture capitalist at Greylock. Chen has a long history with open source - he was on the VMware team that made Cloud Foundry an open source project, and later funded Docker as a VC - and has written a series of articles called Castles in the Cloud. I recently spoke with him as part of Red Hat’s livestreaming show, In The Clouds.

• Digital transformation: Are you working toward the right goals?

  For any digital transformation project to succeed, you need a well-laid-out road map, a clear objective, and bite-sized goals to mark the milestones.

• So this is why Deepin requires so much disk space for installation – LinuxBSDos.com

  Deepin is a desktop Linux distribution with roots in China. It is based on Debian, but ships with its own graphical interface called Deepin Desktop Environment and a set of Deepin-developed tools to go with it. The last version I installed was from 2015, so since I’m gradually coming back to writing for this blog, I decided to test drive the latest edition – Deepin 20.3, which was released on Nov. 25. For me that means installing it in a virtual environment using VirtualBox. For such installations I typically assign the virtual disk 20GB of disk space. And so it was with Deepin 20.3. But that didn’t end well because at some point the installation failed, with the message shown in Figure 2: “You need at least 64 GB of disk space to install Deepin. To get better performance, 128 GB.”
