As you know, sometime Internet is a bad place (and not, I am not talking about Facebook :)

There are “bots” which scans github repo in search of an AWS Keys or other similar api keys, mostly for installing spam bots and so on. You should not version it but… what can you do if your teammate did it already?

This year PiHole protected by home, with an average of 15% of blocked DNS access, every day.

I got an  useful article on additional ads list: https://jussiroine.com/2021/07/goodbye-telemetry-and-ads-running-pi-hole-in-a-home-network/

Also at the end of October CloudFlare released a new DNS for protecting family from malaware and adults-only content, called “Cloudflare’s 1.1.1.1 for Families” and you can find here a simple guide on how to install it.

Sometimes you could have the need to print our humble articles.

We have fixed the HTML CSS to support nice printing browser capability: give a try and let us know.

Lets face it handheld calculators are over priced: a Black and White Casio fx-9860-GIII is priced around 85€ but has only 64kb of working RAM.

Texas Instruments one costs even more.

Numworks offered a color display, 256Kb of RAM and a good GUI at 80€, the same price for a B/W slow Casio entry level. It was the best "Bang for the buck" also for the ability to enable CAS's extensions, via flashing a open source kernel; it was until today....

After creating Misterio, I found this alternative called HarborMaster:

Harbormaster is a small utility that lets you easily deploy multiple Docker-Compose applications on a single host.

It does this by taking a list of git repository URLs that contain Docker Compose files and running the Compose apps they contain. It will also handle updating/restarting the apps when the repositories change.

Turbo Rascal is a development environment for the Commodore computers but also for others like NES and so on.

It is a bit different from other IDE because it is based on a Pascal-like language. It is not easy to compile high level programming language on 6502, but Pascal seems to pay its bill well.

SQLite is a fast, embedded dataabse with tons of feature. Below a set of feature I share with you.

I am not a project manager-born killer, but I learned a lot in my tiny life (and with 20+ experience, I am more or less in the middle of my career).

My rules when I must do an estimation are

1. Tune your estimation on the context. To make simple the explanation, I will divide the estimation in categories; for instance take the fine grained and big cost estimation ones. All fine-grained estimation tasks should be between 2 and 10 days (it is an example). Big cost models are done with 10x or 20x days multiplexer Avoid mixing small estimation with bigger one (i.e. do not mix a task of 5 days with a task of 20 days, reason below).
2. Never never never estimate a task less than two days. As one of my boss said, if you ends before your estimation, no one will complain; but be late of a day...also you have no chances to increase it after declaring it. Every time you open your IDE or answer to a call, two days are gone. In a small company I worked for, it was forbidden to have less than two days on a SAP time capture, because admin's customer invoice management overhead was higher than supposed gain.
3. For fine grained estimation follow the 2,3,5 rules, if possibile

If you follow me, you will end up with a set of tasks with a low standard deviation from the average value. Why this is important? Because estimation is an art.

Suppose you have done a wrong estimation on a task, haven’t you?
