    QB64: basic Revenge

    Quick Basic64 is a QBasic compatible programming language actively mantained.

    It produce C-compiled code and works under Linux and MacOS too. It resemble the original QBasic IDE, and supports its dialect.

    If you have some old qbasic code to "update", QB64 is your best friend:Give it a try!

    runif

    Idempotent and minimal python 3 library for rapid scripting. Provide support for creating file, adding data to them, patching and so on.

    Why?

    (Ba)sh scripting is very easy to setup. So we end up using it all the time for simple procedural script.

    Pi-Hole: per la privacy a casa

    Se vi dicessi che il 20% delle comunicazioni che il vostro smartphone attua per consentirvi di usare Whatupp o leggere il giornale è verso i server pubblicitari di google, facebook, amazon, come reagireste?

    Questo è un articolo divulgativo su uno strumento che è possibile installarsi a casa propria, per proteggere la propria rete Internet dalla pubblicità, e rafforzare la privacy della propria famiglia.

    Chi ha bambini piccoli a casa sa che oramai sono in grado di giocare su smartphone o guardare filmati su Youtube. Si pone quindi un problema che va dal controllo di ciò che guardano, alla loro privacy, passando anche per una riduzione della loro esposizione alla pubblicità.

    Per intenderci, Youtube non ha una grossa considerazione dello spettatore: le pubblicità non sono correlate con i contenuti, e anche abilitando i filtri per adulti il risultato è che non c’è un controllo su cosa vedono i nostri figli; tradotto in parole semplici, pubblicità inappropriate possono apparire durante la visione di un cartone animato LEGO.

    Sto parlando di tutte cose che ho toccato con mano, e fornirò conferme con riferimenti ad altri articoli. Non è mia intenzione allarmare nessuno, ma sensibilizzare tutti sulla esistenza di una onda crescente che sta cercando (in sordina) di imporci un modo di vivere che non dobbiamo per forza abbracciare.

    The project has been renamed into “runif”. This page left only for Google Search happiness.

    Pybash is a python library to make python script as easy as in Bourne Again Shell (Bash).

    Bash scripting is very easy to setup. So we end up using it all the time for simple procedural script.

    On Constants

    I think constants are evil (just joking but….I will explain why).

    I am tired of seeing a lot of Java classes filled with the same constants repeated over and over again, instead of collecting them in a common file, which in C Language was called include files (ooooah!).

    Comments are evil?

    In the 1980 comments were used to reduce the “gap” between unstructured code and “rationale” behind the code.

    1. C/64 Peek and poke where oscure.
    2. Gosub on function pointed by numbers was bad
    3. 8-bit systems was tight on command names and so on (think to write a python interpreter in Arduino/bbc:Micro, or look at the memory consumed by the COMMAND STRINGS on C/64 Basic v2)
    4. C code was not expressive, but good code required little comment, as you can see here
    Today comments are used to:
    1. Comment obscure code -> instead of writing it better
    2. Comment caching code you will end up to commit breaking production ->instead of having a cache config to disable cache on dev machines
    3. Comment not working code will end up in production, producing functional breaks -> because you will forget it and  commit the bad version
    When I am sent on a Red Project, the code is often obscure and not commented at all. So I dare to suggest to deprecate comments at all, replacing it with a set of meta annotation like:
    @Comment("Documentation of this class/method/function/closure")
    @Fixme("Reason")
    @Todo("Why",  deadline=20230423)

    UTF-8 and Unicode Standards

    Character encoding is a very bad beast when you write code, but UTF-8 will save us.

    Belive me: You will love the Big Brother and the UTF-8.

     

    Unicode Transformation Format 8-bit is a variable-width encoding that can represent every character in the Unicode character set. It was designed for backward compatibility with ASCII and to avoid the complications of endianness and byte order marks in UTF-16 and UTF-32.

    The department of defense, has published a nice document to “detect” agile bullshit. The document is called DIB_DETECTING_AGILE_BS_2018.10.05 and was published on October 2018.

    Because some friend of mine did not know about RUP, and deal with waterfall process, I decided to make a small recall for all poor young Project Manager dealing with bad developers, bad consultants and so on, out of there. From Wikipedia:

    The Rational Unified Process (RUP) is an iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003.[1] RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. RUP is a specific implementation of the Unified Process.

    Exploring a 23 years old code base: LambdaMoo MUD Part 2

    In this second article I will continue my jorney on LambdaMoo code base. The C code is very well written. Sometimes the API abuse global variable to avoid passing around identifier like output database file descriptor or the like.

    Because a lot of the system has been written in the Moo language, the core is composed of:

    Exploring a 23 years old code base: LambdaMoo MUD Part 1

    On these days my greek daemon (the one which talk to me about deep nerd programming) was interested on LambdaMoo.

    LambdaMoo is an Object Oriented Multi User Dungeon born back in 1995. A MUD was a text based system you log in, talk with other, create adventures and so on. LambdaMoo has a script language and the entrire system could be customized.

    The LambdaMoo last version 1.8.3 was a work in progress in 2008. LambdaMoo today is 23 years old.

    So my daemon asked me: if you were able to do a  tech refresh of LambdaMoo, waht will you eventually suggest?

    To respond to this question, I need to study the original code

    Meltdown and Spectre

    Meltdown and Spectre are two big vulnearbilities found in Intel and AMD chips out of there. The vulenarbility is so huge it affects up to 1995 chips.

    On the raspberrypi, there is a very nice explanation of what Meltdown is.

    First of all, the one who discovered this bug is a GENIUS, for sure.

    Vjdbc is a remote access for JDBC-Datasources developed more then ten years ago (last news are from 2007, with last comit from 2013.

    The project was migrated to Maven 3, but the code base is very old.

    I decided to give it a try, spin a github repository and started working on it, because you know, is nice to have a database driver proxy-logger :)

    La mia esperienza nell'open source

    Nel 2011,  per studiare node js creai un progetto chiamato OrgModeParser.

    Org Mode è un package per l’editor Emacs, ed è pensato per tenere note strutturate, pianificare progetti con una schedulazione, mantenere una lista di cose da fare e generare poi documenti word o html da tali file in modo piuttosto efficace.

    AngularJS alterantive: Micro JavaScript framework on the 2017

    AngularJS is indeed a good framework, but if you lose some grip on it (i.e. you go in vacation for 2 weeks), it is very complex to re-grasp.

    Also I have seen junior JavaScript developer confused my $scope use.

    JavaScript on client side has damned destiny: it is too easy to develop a framework from scratch: so roll you dice, cross your finger and find plenty of AngularJS alternatives
