Posted on

Hiring IT specialists is a challenging task. Firstly, there is currently a shortage of experienced professionals in the market, and they know it. Candidates are often not willing to spend a lot of time on "selection activities" from employers unless they're initially interested. The previously popular practice of "giving a test for 8+ hours" is no longer effective. For an initial assessment of knowledge and screening candidates before conducting a full-scale […]

The PIM protocol is a set of protocols for multicast transmission in networks between routers. Neighbor relationships are established similarly to dynamic routing protocols.

Release of GNU LibreJS 7.20, an add-on for blocking non-free JavaScript in Firefox

Posted on

The release of the Firefox add-on LibreJS 7.20.1 has been announced, which allows users to avoid running non-free JavaScript code. Richard Stallman believes that the issue with JavaScript is that the code is loaded without the user's knowledge, leaving them unable to assess the level of its freedom before it is loaded and preventing the execution of proprietary JavaScript code.

Terraformer — Infrastructure To Code

Posted on

I would like to talk about a new CLI tool I created to solve an old problem. The issue surrounding Terraform has long become a standard in the DevOps/Cloud/IT community. It is very convenient and useful for dealing with infrastructure as code. There are many delights in Terraform, as well as many pitfalls, sharp knives, and rakes. Terraform makes it very easy to create new things.
