On my 13 years old ThinkPad W520 from 2011 I managed to do that in 4:23 total time. As previous leader used IceWM for the task – I have chosen Openbox as its also small. The operations and ...

Many times I wrote about FreeIPA/IDM – but I have one problem with it – its not currently possible to run FreeIPA on FreeBSD … so I searched for other open source alternatives and found Keycloak. What surprised me even more is that its even available in the FreeBSD Ports as net/keycloak port. So I wanted to check ho...

In the open source world everything lives/evolves/changes. This is why the new version of connecting latest FreeBSD 14.0-STABLE system to the FreeIPA/IDM is needed. One of the things that changed is that security/sssd is now deprecated and security/sssd2 is its successor. Also new version of ports-mgmt/poudriere-dev...

I hold an unpopular stance: code comments are as important as the code itself. OK, maybe that’s a little overstated, but I maintain that code comments are critical to code readability and maintainability. Before you see if I weigh more than a duck, please hear me out… When I was a college undergrad, I had the privil...

Last time when I wrote Tiny UPS for Tiny NAS – I fucked up. I did not tested the solution enough and provided false information – I apologize for that.

I am a big fan of building things by yourself. That also includes my NAS instead of using something prebuilt such as some Synology or QNAP NAS box. Although I must say that these small NAS devices with 2.5 disks slots like Synology DS416SLIM or QNAP TS-453S PRO look really interesting … if I could only put FreeBSD t...

A couple of weeks ago I wrote a blog posting here about Fedora having frame pointers (LWN backgrounder, HN thread). I made some mistakes in that blog posting and retracted it, but I wasn’t wrong about the conclusions, just wrong about how I reached them. Frame pointers are much better than DWARF. DWARF unwinding mig...

The primary motivation for defining a class in C++ is to reflect and maintain a class invariant. In this post we will see what class invariants are and how you deal with them.

I’ve wanted to revisit “Tail Call Optimization in Elixir & Erlang – not as efficient and important as you probably think” (2016) for a while – so much so that I already revisited it once ~5 years ago to show off some benchee 1.0 features.
