  • 8 new rules for winning the IT talent battle | The Enterprisers Project

    The predicted turnover tsunami is well underway, with enterprises across industries facing record-high IT talent losses. Attrition rates had risen an average of 10.5 percent over the previous quarter, according to an August 2021 quick poll conducted by Everest Group, with more than one-third (36 percent) of respondents reporting increases of more than 11 percent over the previous three months. “We are definitely seeing attrition rates starting to rise,” says Michel Janssen, chief research officer at Everest Group. “It’s becoming an across-the-board issue.”

    The resulting battle for technology pros hitting the market is bound to grow more intense. Yet only a minority of enterprise IT organizations have the kind of well-defined and proactive strategies needed to ensure some level of predictability in their workforce pipelines in this challenging environment.

    Everest Group has taken research from its strategic IT workforce development assessments to examine what the highest-performing IT functions (those that achieve the greatest business, operational, and cost impacts) are doing to address current talent gaps and prepare their workforces for the future. They discovered that it’s not the biggest companies – or those with the most money to spend – who perform the best.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
