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.

....

Do you have a work server that you want to run a few small services on, but don't want to have to manually manage it? Do you find that having every deployment action be in a git repo more tidy?

Harbormaster is for you.

E’ con rammarico che scrivo queste note, e ripoto qui solo le mie opinioni a “caldo” 

Iniziamo dai lati postivi: Evangelion: 3.0+1.0 Thrice Upon a Time è disegnato benissimo, un film degno del 2021. Anche lo stile è molto avanzato: vengono inseriti sia disegni a mano, che sequenze 3D oltre a sequenze “miste” in bianco e nero e alcune citazioni dalla prima puntata. La scelta della colonna sonora è buona, e denota una certa cura. I combattimenti sono veloci, e fulminanti nello stile di Evangelion.

«L’appello a non vaccinarsi è un appello a morire»
Mario Draghi rispondendo ad una domanda diretta di un giornalista, il 22 luglio

 

Premessa: benché disprezzi le fake news e le idee deirlanti, posso comprendere chi non voglia vaccinarsi (per ragioni sue, intendiamoci, non per paura di essere "radiopilotati" da Bill Gates).
E' una scelta che però va presa soppesando anche le conseguenze che comporta per la propria vita civile.

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?

La fine di Forza Italia sembra vicina: sta perdendo pezzi (vedi la scissione di Toti), e la mancanza di una successione a Berlusconi è un vulnus che sembra insanabile.

Si vocifera che la Lega voglia proporre una fusione dei gruppi parlamentari tra Lega e Forza Italia.
