Wellcome, my name is Pasquale Frega and I am a freelance IT specialist, developer / programmer and consultant of GNU/Linux systems administration and security. I started programming when I was 8 years old in BASIC on an Atari XEGS. In the past I've programmed in C, Tcl/Tk, Lua and Lisp, now mostly in Java.

Secure USB

This tutorial explains how to easily create a hidden directory inside any FAT-formated USB storage device. Please follow the instructions:

insert the device, download this archive, copy and unzip it inside the device (better if empty);
do double-click on win.bat if you use Windows, or on lnx.bat if GNU/Linux, in which case fatattr must be installed first;
delete secure_usb.zip, win.bat, lnx.bat and the readme file.

Now you have a hidden directory called .data where you can copy documents, files and applications and keep them away from prying eyes. To show that directory on GNU/Linux with Gnome desktop, in the Nautilus file manager simply press Ctrl+H, press again to hide it anew. A similar way on macOS, in the Finder file manager press Command + Shift + . (full stop/period), press again to hide it anew. On recent Windows follow the illustration below.

led

led is a simple and easy-to-use but yet powerful line-oriented text editor; almost everything in this site has been edited or developed by it. It is written in Urn Lisp and compiled to Lua, so it is available for every platform where Lua (version 5.1 or higher) is available as well; however some special features are available only with Lua 5.1 (or LuaJIT) on AmigaOS, MorphOS, AROS and UNIX with XTerm.

It is chosen by 1000+ system administrators and developers as their every-day editor.

The latest release now supports also scripts for text processing.

JSchemePlus

JSchemePlus is an hack of Jscheme 1.4 by Peter Norvig. It is basically the same, however it allows to redistribute a script in an executable JAR file of only ~40K, simply make a copy of runtime.jar, e.g. cp runtime.jar my-jar.jar, name the script as main.scm and insert into this JAR, e.g. zip -u my-jar.jar main.scm, then execute it, e.g. java -jar my-jar.jar
JSchemePlus does not get command-line arguments as list of scripts to execute, only the first one is executed, the others are passed to this script and stored as list of strings in *arguments*. It implements all of R4RS with a lot of additional functions, like: (execute command) (random) (sequence from up-to step) (split list element) (string-split string sub-string) (read-all-from-file file) (write-to-file file data) (file-size file) etc... For the complete list read the HELP file or type (help).
JSchemePlus needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install; click here to get it for any operating system.

About Scheme, it is a Lisp dialect that allows to write programs and scripts quickly and easly. It is a different language, even compared to other Lisps; it is not difficult, only a bit different. The following is an example of recursion:


(define (sequence from up-to step)

 (if (and (integer? from) (integer? up-to) (integer? step) (<= from up-to) (positive? step))

  (let ((_sequence '()))

   (define (loop _var)

    (if (< _var from)

     _sequence

     (begin

      (set! _sequence (cons _var _sequence))

      (loop (- _var step))

     )

    )

   )

   (loop up-to)

  )

  '()

 )

)

The following is an example of iteration:


(for-each (lambda (_num)

 (if (odd? _num)

  (display _num)

  (newline)

 )

) (sequence 1 10 1))


1

3

5

7

9

()

It checks each number from 1 to 10, if this is odd it prints this, otherwise it prints a newline. Finally, it returns nothing (empty list). For more information and examples, see the reference documentation.

TkLauncher

TkLauncher is a small desktop launcher for GNU/Linux, but easy to compile also elsewhere. It is very simple, provides a small gadget on the bottom-right corner of the screen where you clicking appears a launcher with some icons. TkLauncher reads a configuration file on your home directory, .tklauncherrc; at the first running it creates one if does not exist. Edit this file to set it.
I have wrote TkLauncher mainly for my prefered window manager, amiwm, so it is tested especially with this; however it should work also with the others, I think, without problems. It is different but recalls, more or less, AmiDock on AmigaOS 3.x.
TkLauncher is written in Tcl/Tk and C and is distribuited as a classic tarball. It is light and fast so you can use it also on old computers with few resources. It is nice and works fine, however sometimes after you have dragged the top bar of the amiwm, it does not work any more (I do not know why) and you have to reset amiwm. I provide also a small module to use with this window manager.

RetroLook

RetroLook is a simple window manager for X11 wrote in Tcl/Tk and C. It is based on TKWM that, where possible, has been cleaned and fixed. RetroLook makes your desktop looking like it was in the '80 years. It recalls AmigaOS 1.x, in particular the 1.4 (a version never released), because it had planned the maximized button. It supports also sloppy focus, close button, stack buttons and resize button. Clicking on the title bar or on the right bar also does raise and focus. There is nothing to configure, no wallpaper, no color scheme, no fonts, etc... Also it does not support virtual desktops. There is not plan to support such things. It works only with a simple menu file in the home directory, ~/.retrolookmenu, with simple items, no submenu's.

It needs: Xop 0.4, Rootwin 0.4, Foreignwin 0.1; may be also tcl2c; Tkimg is not mandatory.

May be usefull for coding and testing purpose.

King James Bible

The King James Version (KJV), also known as the King James Bible (KJB) or simply the Authorized Version (AV), is an English translation of the Christian Bible for the Church of England, begun in 1604 and completed/published in 1611 under the sponsorship of King James I. The books of the King James Version include the 39 books of the Old Testament, an intertestamental section containing 14 books of the Apocrypha, and the 27 books of the New Testament.

Yet today it is one of the best and more important English version of the Christian Bible.

Because its age now it is public domain (copyright free).

This release is the first version of the 1611 in EPUB and MOBI formats for Amazon Kindle and other eBook readers and tablets; for other devices please download and install FBReader. It is very easy and very comfortable to read because it includes hyperlinks for every book, chapter and verse.

Sutra del Cuore e Diamante

Il Sutra del Cuore della Perfezione della Saggezza o Sutra del Cuore (sanscrito: Prajñāpāramitā Hṛdaya) è un Sutra Mahāyāna del gruppo della Prajñāpāramitā, molto conosciuto e diffuso nei paesi di tradizione Mahāyāna per la sua brevità e densità di significato. Si ritiene che sia stato composto intorno al I secolo d.C. nell'Impero Kushan. Consiste di soli quattordici śloka (versi) nella versione in sanscrito e 260 caratteri nella versione cinese più diffusa. L'argomento del Sutra è la formulazione della dottrina della "vacuità" (o letteralmente: "vuotezza", sanscrito śūnyatā) ovvero la insostanzialità (o non esistenza intrinseca) di tutti i fenomeni. Il Sutra si apre con l'esperienza della "visione profonda" ottenuta dal Bodhisattva della Compassione Avalokiteśvara. La "visione profonda" rivela l'insostanzialità (śūnyatā) dei cinque skandha (elementi): forma (o materia, rūpa), sensazione (vedanā), percezione (saṁjñā), discriminazione (aggregati o costrutti mentali, samskārā), e coscienza (vijñāna); cioè tutte le parti in cui tradizionalmente è articolata, secondo la filosofia buddhista, la realtà fisica e psichica.

Il Sutra del Diamante è un celebre breve Sutra Mahāyāna della classe dei Sutra della Prajñāpāramitā. Nelle grotte di Mogao a Dunhuang, l'archeologo britannico Aurel Stein trovò nel 1907 una copia del Sutra del Diamante nella traduzione cinese di Kumārajīva che risultò essere il più antico testo a stampa oggi esistente, risultando quindi il testo completo a stampa più antico con datazione certa, precedendo la Bibbia di Gutenberg di ben 587 anni. In esso il Buddha espone all'anziano discepolo Subhūti quale sia la pratica che deve seguire chi volesse perseguire la via del Bodhisattva.

Queste versioni in Italiano sono in formato EPUB e MOBI per Amazon Kindle ed altri eBook reader e tablet; diversamente è possibile scaricare ed installare FBReader. Sono molto facili da leggere in quanto includono un comodo indice con hyperlink.
