  • Rolex di cittadinanza

    Ritengo abbastanza sterile la notizia del rolex di uno dei candidati di Calenda, che ha scatenato l’odio in rete, poché criticava il reddito di cittadinanza. Però l’evento aiuta a spiegare spesso le dinamiche italiane. Ci sono parecchi dati che certificano che il reddito di cittadinanza non ha creato più lavoro, e quindi ha fallito. Mi ricordo che molti evidenziavano questo rischio proprio poco prima che fosse approvato.

    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.

  • Perché Evangelion 3+1 non mi è piaciuto (pochi spoiler)

    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.

    K8s done right Part 1: start from helm charts

    K8s is a very complex beast. But it give you a very good set of security defaults, and it is also a very well done implementation of a microservice application.

    After installing Docker Swarm on some Customer, we are giving up on Swarm because the Enterprise version was acquired by Mirantis and now is marketed like “K8s” engine,  so Swarm seems K8s right now.

    «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.

    Open calculator (aggiornato)

    Voglio raccontarvi una storia, per spiegarvi quanto è difficile conciliare la vendita di un prodotto commerciale con lo sviluppo di un software "open". Al giorno d’oggi le calcolatrici scientifiche sono un mercato con parecchia concorrenza, e lo prenderò come esempio.

    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.

    Meltdown and Spectre Mitigation removal

    Some time ago I stumbled upon this Hacker News discussion on how disable Spectre mitigation.

    (For what Meltdown and Spectre is, refer to this article on 2018)

    It is sad to say but my Intel NUC centrino was slowed down a lot by these mitigation, and the same faith is shared by old Intel server. Disabling it on Linux and Windows has a very huge improvements.

  • Simple estimation rules for young programmers: 2,3,5

    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?
