At the Command Line • Working at the command line is both anachronistic and thoroughly modern.

On the DVD

Tech News

Common Core • ASP.NET Core enables the development and operation of dynamic web applications.

Mail Manager • Exchange Web Services (EWS) is an important interface that lets applications access Exchange content. You can access the EWS mailbox via PowerShell or create your own tools.

Private Chat • With clients for all popular distributions, the decentralized messaging app Jami promises maximum anonymity for chats, voice calls, and videoconferencing

Micro Cures • In contrast to legacy systems, container-only distributions make do with an absolute minimum of software, which radically simplifies maintenance.

Synchronicity • If you use your Google account to synchronize appointments between your smartphone and your desktop computer, you can do this just as easily with an open source solution

Many Cooks • People say many cooks spoil the broth, but collaborative editing of documents does not necessarily have to end up in chaos. The collaborative functions in these free online office solutions can help users with teamwork.

Hosted Office: What to Consider

Interlocked • VMware positions their vRealize management suite to make hybrid cloud/on-premises setups palatable to customers.

Key to Success • If you want to build scalable clouds, you need the right hardware, but which servers are the right choice as controllers, storage, and compute nodes?

A Curse and a Blessing • With the need for home offices during the pandemic lockdown, provisional solutions instituted on the fly during the transition from office to home require more permanent solutions, especially for securing TLS connections on the Internet.

All Yours • A private Docker registry gives you more control over images and protects your Docker Hub credentials.

Optimized Throughput • Filtering HTTP connections and employing traditional proxy servers can protect users from web threats but also increase latency. DNS filters would be a better option, but they lacked authentication – until NxFilter came along.

Self-Regulating • Chef InSpec is a practical tool for automated compliance monitoring with an intuitive, declarative scripting language.

Group Dynamics • Kopano Groupware seeks to be more than a slot-in replacement for Microsoft Exchange. We reveal how you can commission the platform and the highlights it offers.

SSHFS for Shared Storage • SSHFS is often overlooked as an HPC shared filesystem solution.

Critical Tool • The crictl troubleshooting tool and runc container runtime pair up to help identify and diagnose issues with Kubernetes Pods and clusters.

Standing Alone

Parallel Paths • Tap into the power of MPI to run distributed Python code on your laptop at scale

Clean Start • A Perl script strips HTML markup, creating text files, and makes each file an entry in a database.
