Programming is like writing.Code must be easy to read, and understand. For this reason I do not like very much technologies like:

I the last years I decided to put a stop on my RasperryPI2 and have a mini pc always on.
It is a very slow centrino with 2 CPU threads and 8Gb of RAM, a huble micro SATA SSD and works great with Debian Linux. I use it as a benchmark to understand if a project is worth studying: if the CPU Load stay low, the code is very well written.

A friend of mine asked some insight on how to harden a Gitea server on Internet. Gitea is a web application for manging git repositories.

Do you STILL love taking notes by hand? I have created different types of composition notebook, even retro-style one, inspired by MOS6502, with Sprite Editor sheets, and some nice goodies. Give them a try!

Bullet points:
- 1979: Unix V7 Introduced the chroot command to isolate the filesystem a process "access" to.
- Various technology was introduced up to 2006, like Virtuozzo (which patched Linux in a proprietary ways)
- 2006: Process Containers Launched by Google in 2006 was designed for limiting, accounting and isolating resource usage (CPU, memory, disk I/O, network) of a collection of processes. It was renamed “Control Groups (cgroups)” a year later and eventually merged to Linux kernel 2.6.24.
- 2008: LXC LXC (LinuX Containers) was the first, most complete implementation of Linux container manager. It was implemented in 2008 using cgroups and Linux namespaces, and it works on a single Linux kernel without requiring any patches.
- 2013: Docker Docker used LXC in its initial stages and later replaced that container manager with its own library, libcontainer. Docker offered a way to configure and manage containers, i.e a standard de-facto for this technology. As you see Docker was based on cgroups and LXC, seven-years old technologies
- On September 2014 Google published the first release of Kubernetes
- In 2015 Docker, CoreOS and others founded the Open Container Initiative's (OCI). K8s does not need docker anymore to work, but Docker traction is still strong.

NILFS is a log-structured file system supporting versioning of the entire file system and continuous snapshotting, which allows users to even restore files mistakenly overwritten or destroyed just a few seconds ago.
Discussion on Hacker NewsNILFS was developed by NTT Laboratories and published as an open-source software under GPL license, and now available as a part of Linux kernel.

Nice tool to test:
Git hook scripts are useful for identifying simple issues before submission to code review. We run our hooks on every commit to automatically point out issues in code such as missing semicolons, trailing whitespace, and debug statements. By pointing these issues out before code review, this allows a code reviewer to focus on the architecture of a change while not wasting time with trivial style nitpicks.
As we created more libraries and projects we recognized that sharing our pre-commit hooks across projects is painful. We copied and pasted unwieldy bash scripts from project to project and had to manually change the hooks to work for different project structures.
