Once upon a time there was a small company in the south west of Germany that used an old check plugin for monitoring its network devices. But as their network got bigger and bigger over time, the plugin (written in Perl) became more greedy than ever before and swallowed all of the available resources. The CPUs were melting and the RAM was about to collapse. So a small team of creative software developers decided to take the fate of their company into their own hands.

The COVID pandemic has redefined the workplace and accelerated the process of digitization for many. Organizations are migrating to systems that are flexible, distributed and resilient. Per Gartner, IT spending will reach $3.9 trillion worldwide in 2021. IT teams will be channeling investments into enterprise software as remote work becomes essential. Systems that support remote work will see a growth of 8.8 percent this year.

“Object Reference Not Set to an instance of an object.” Cast the first stone those who never struggled with this error message when they were a beginner C#/.NET programmer. This infamous and dreaded error message happens when you get a NullReferenceException. This exception is thrown when you try to access a member—for instance, a method or a property—on a variable that currently holds a null reference. But what is a null reference?

Data platforms — or databases with sets of APIs for flexibly working with data — are quintessential backbones for those who rely heavily on being able to change how they obtain data and work with their data over time. A good data platform will provide you the necessary tools to glean the insights you need to solve tangible problems. That platform should also hopefully make it so you don’t have a bad time doing it!

In the new light of website performance that I’m pursuing, I have learned to avoid Javascript at all costs. Here’s a nice Javascript-less desktop and mobile navigation update that we’ve added to our website. Inspired by Dirk Olbrich’s Hugo Starter Theme with Tailwind CSS this works by displaying a regular navigation bar on landscape tablets and desktop resolutions, but changes into a nice dropdown on mobile resolutions.

When using Nagios, the NRPE daemon has been the traditionnal solution to implement local checks (load, number of users, custom scripts, etc.). All other checks are performed remotely from the Nagios server. NRPE daemon has been a bit challenging as you need to keep it in sync with your Nagios server and sometimes backporting this daemon can be painful. As Glouton has been implemented in Go, when you need a Nagios NRPE daemon, you can just use the binary on any compatible system and voila.
