As I promised about 4 hours ago, here is my introduction to Hyper Text Transfer Protocol in form of a mind map.
It is to be intended as a really short introduction to this protocol. Like the previous one about computer networks, the mindmap summarizes materials copyrighted by Tanenbaum and also material taken from Wikipedia.

The topics covered are:

• Scope of the protocol
• HTTP connection
  • HTTP/1.0
  • HTTP/1.1
• HTTP request methods:
  • GET
  • HEAD
  • PUT
  • POST
  • DELETE
  • TRACE
  • CONNECT
  • OPTIONS
• Message Headers
  • Request Headers - all
  • Response Headers - all
• Status Codes:
  • 1xx Information
  • 2xx Success
  • 3xx Redirection
  • 4xx Client error
  • 5xx Server Error
• Sessions:
  • Cookies
  • Server-Side sessions
• Secure HTTP - HTTPS:
  • By URI scheme
  • HTTP Upgrade Header
  • SSL/TLS

You can browse an HTML version online.

You can download:

• Mindmap source file (Freemind)
• An export in PDF format
• An export in PNG format

As always, you are free and encouraged to contact me in case of errors or anything else.
Hope you like it!

Lettera aperta ai visitatori:

Caro Visitatore,

Se sei uno studente di Design alla LUB e sei capitato alla mia vecchia pagina intitolata "Un messaggio da quelli di design?", vedi di leggere bene il contenuto della pagina e di distinguere ció che scrivo io, unico autore del blog, e ció che scrive qualsiasi altra persona. Trovo infantile il modo in cui alcune persone si siano accanite su di me confondendomi con ció che hanno scritto altre persone sotto forma di commento.
BD-things.net é un blog/sito che raccoglie articoli e pensieri informatici, soprattutto in inglese e che non hanno quasi mai a che fare con la Libera Universitá di Bolzano. Men che meno con la Facoltá di Design, che si é meritata un mio singolo post. E proprio per niente con sclerate contro gli studenti di Design, persone che non ho mai giudicato male.

Se sei uno studente di Informatica e ce l´hai coi designer della LUB, leggiti un articolo informatico del mio blog o prendili per il culo per i fatti tuoi da un´altra parte se ci tieni, a me non interessa prendere in giro le persone che frequentano design. Ci sono altri blog che lo fanno, non il mio.

Sei sei una qualsiasi altra persona che capita su quella pagina, evita di sparare a zero su studenti di design o su studenti di informatica applicata. Se hai critiche costruttive scrivi pure.

Grazie,

L´autore del blog e unica persona che lo gestisce

Daniel Graziotin.

I really like (and miss) Linux Mint Menu (mintmenu), so I installed it on my Debian Sid box and here is how I managed it:

• Install mintsystem and mintmenu deb packages, either by adding mint repository to yout sources.list file or by downloading them from mint packages or simplier, by grabbing them from my blog
• Help it to recognize your applications by symlinking some files in /etc/xdg/menus (as root):
  

  ln -s gnome-applications.menu applications.menu
  ln -s gnome-preferences.menu preferences.menu
  ln -s gnome-settings.menu settings.menu

• Add mintMenu to your Gnome panel..

et voilà! Here are the two deb files I'm using:
mintsystem_61_all
mintmenu_4.2_all

Here is an updated screenshot:

MintMenu complete under Debian Sid

If you also want to enable beagle or tracker, be sure to add the correct search command in the preferences of mintMenu (see the screenshot)

It's a very long time since I abandoned Ubuntu, 1 year and 9 months being precise, although I continued to use Ubuntu derived distros.
I decided today to give Ubuntu 8.10 beta a try. Obviously, every time I decide to try a Gnu/Linux distribution it happens that a new release comes out: I downloaded Alpha 6 yesterday, I fell into problems with it and a apt-get update && apt-get dist-upgrade brought me Ubuntu 8.10 beta, correcting some of them
(more...)

I began today to check my theme pages for passing W3C's Validator test against XHTML 1.0 Strict. There is still some work to be done before it will be ready but I would like to share with you a modified version of the very useful Expanding Text Plugin for Wordpress, which lets you to create blocks of text in posts or which either expand or collapse when clicked on. I really like the plugin, but I noticed that it does not produce valid XHTML tags. Here is a light modification of the plugin which outputs valid XHTML blocks: dd-expanding-text-valid-xhtml

When I announced BD-incollo 6 days ago, I also mentioned that I would have launched the service today. I really did that, and I'm very proud to announce the first site that runs BD-incollo.
http://incollo.com! Very easy
Incollo.com is a collaborative debugging tool like Pastebin or other similar services, but it's slightly different from it. And it's different from other Pastebin clones even written using Rails or Django.
Here are the most exciting features:

• It's Fast. Very Fast
• Written thinking about usability
• A very clean interface, a minimalist design that gives space to the code (as it should always be)
• It's possible to search through pastes, like in a forum
• A Paste is not deleted after 30 days or something similar. A paste is deleted after it is no more interesting! It's deleted after 60 days of no visualizations
• The system is anonymous. It won't store your information! Paste whatever you want but please use your brain! A Paste may be reported to the administrator!
• You don't really have to play with options and there are no required field other than the Paste itself. You may paste a text and directly hit the submit button
• Quite every page is XHTML 1.0 compatible
• It works well and has nice urls, thanks to Django
• Compatible with every browser (tested with Internet Explorer 6,7,8, Mozilla Firefox 3, Apple Safari, Google Chrome)
• Resolution friendly! Liquid design that adapts to every monitor resolution (tests from 1024x768)
• Developer friendly! Every functionality of incollo.com can be used with max 2 mouse clicks and without a mouse scroll!
• Tested with lots of pastes, quite every source code should be perfectly viewed (this does not happen with every pastebin clones I've tried)
• Uses Pygments for code highlighting
• Languages supported: ActionScript, Assembly (various), Boo, Befunge, BrainFuck, C, C++, C#, Common Lisp, D, Delphi, Dylan, Erlang, Haskell (incl. Literate Haskell), Java, JavaScript, Lua, MiniD, MooCode, MuPad, OCaml, PHP, Perl, Python (incl. console sessions and tracebacks), Redcode, Ruby (incl. irb sessions), Scheme, Visual Basic.NET, Django/Jinja templates, ERB (Ruby templating), Genshi (the Trac template language), Myghty (the HTML::Mason based framework), Mako (the Myghty successor), Smarty templates (PHP templating), JSP (Java Server Pages), , Other markup, , Apache config files, Bash shell scripts, BBCode, CSS, Debian control files, Diff files, Gettext catalogs, Groff markup, HTML, INI-style config files, IRC logs (irssi style), Makefiles, MoinMoin/Trac Wiki markup, Redcode, ReST, SQL, also MySQL, Squid configuration, TeX, Vim Script, Windows batch files, XML

This is an example of Paste with Incollo.com:

You are really welcome to report any bugs or leave a feedback! Remember that this is my very first Django project, and I created it in about 6 days!

Of course, I'm already beginning to think about new features
