The Coolest Server Names - Stack Overflow

On Stack Overflow web site we read (bold by us):

The funniest server name story I have is from when I worked at the Kennedy Space Center. On our particular project, our main server was named snowwhite, and the 7 client workstations were named after the Seven Dwarves. The kicker is, one day one of our engineers ran into a Disney Imagineer who worked at Walt Disney World, and they started talking about server names. The Disney Imagineer said "that's funny, we have a group of servers named columbia, challenger, atlantis, and discovery."

Python 3.0
We are pleased to announce the release of Python 3.0 (final), a new production-ready release, on December 3rd, 2008.

Python 3.0 (a.k.a. “Python 3000” or “Py3k”) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places.

Singleton Design Pattern in Java

Il design pattern Singleton è il primo design pattern in cui si si imbatte, ed è molto importante anche perché aiuta a comprendere meglio i linguaggi OOP.

Potete trovare un’ottima introduzione presso Wikipedia, dove leggiamo:

Il metodo più semplice per implementare questo pattern è quello di rendere privato il costruttore della classe impedendone così l'istanziazione diretta, e nello stesso tempo fornire un metodo getter statico che restituisca ogni volta la stessa, unica, istanza

Ecco un esempio in Java:

public class MioSingolo {
    private static MioSingolo istanza = null;
private MioSingolo() {}

public static MioSingolo getMioSingolo() {
    if (istanza == null) {
        istanza = new MioSingolo();
    }
    return istanza;
}

}

Ecco lo stesso esempio thread safe…

La scelta di un Content Management System (CMS) è spesso cruciale, soprattutto se dovete usarlo per creare un sito per un utente finale poco smaliziato.

Vi sono così tanti software di CMS, che scriverne uno da zero è quasi sempre un’opzione da considerare con molta cautela.

In questo articolo prenderemo in esame tre CMS scritti in PHP, molto diffusi e con un nutrito numero di fan.

Il seguente esercizio operativo serve per prendere confidenza con:

Libreria Java Servlets & JSP
Libreria Log4J

Si richiede di creare una pagina jsp che consenta di modificare dinamicamente alcuni livelli di logging:

Dettagli:

Si richiedono 5 livelli di log (qui ne sono mostrati solo 3 per semplicità)
Si richiede di poterli configurare modificando un solo punto (es 5 var nascoste nel form)
Si richiede di poter configurare la password (idem come sopra)
Se la password è errata il sistema registra su un log l'errore e non fa nulla, ripresentando la maschera.

I dati della crisi

In un articolo del corriere della sera del 19 novembre 2008, leggiamo un inciso che dà un’idea della crisi in atto. Si riporta una discorso del ministro del Tesoro Henry Paulson (grassetto nostro):

Paulson [...] ha spiegato che, anche se la crisi rimane grave, non è cosa da poco che il sistema sia sopravvissuto a una spaventosa distruzione di ricchezza. Ed ha fornito un dato impressionante: le istituzioni che nei mesi scorsi «sono fallite o hanno vissuto una situazione che equivale a un fallimento», e cioè Bear Stearns, IndyMac, Lehman Brothers, Washington Mutual, Wachovia, Fannie Mae, Freddie Mac e il colosso assicurativo Aig, all' inizio del 2008 avevano un patrimonio complessivo di 4,7 trilioni di dollari: una cifra pari a due volte e mezzo il Prodotto interni lordo dell' Italia. Una ricchezza andata quasi completamente in fumo.

Che sia semplice!

A Gioorgi.com VIC 20 Boot Screen ci occupiamo di software da molto tempo. Giovanni Giorgi respira il software dalla metà degli anni ottanta, quando il Vic 20 fu commercializzato in Italia (abbiamo trovato molti dettagli sul nome e la storia del VIC-20, ma la fonte più attendibili è sempre wikipedia).

Dopo così tanto tempo, possiamo affermare uno dei principi fondamentali che qualsiasi persona si occupi di software deve tenere a mente.

Non importa se siete account, ingegneri, responsabili di marketing o semplici sviluppatori junior. Dovete sempre tenere a mente che il software che producete deve essere facile.

Commodore BASIC as a Scripting Language Open Source

Commodore BASIC as a Scripting Language for UNIX and Windows - now Open Source:

Here is a little background:
This application is a recompiled version of the original Commodore 64 binary - it is not a reimplementation, so while it runs at pretty much the maximum possible speed, it is still 100% compatible. The huge C file in the archive has been produced by feeding the original 6502 code into my static recompiler and optimizing it with LLVM. The original operating system interface (character I/O, LOAD, SAVE etc.) has been reimplemented in native C, so Commodore BASIC interfaces nicely with OS X/Windows/Unix - you can use pipe I/O, and you can pass the filename of a BASIC program on the command line.

Selling software which is of some value

At Gioorgi.com, after working with a lot with software for over twenty years, we have envisioned a clear idea about open source. This is the second article of a series tagged “opensource”: the previous one is Open Source for the infrastructure; in such article we started to do some tiny consideration of the destiny of big closed huge framework. Things are getting bigger and bigger, and maintaining big code library is a high cost for software house

In the 2008, when I look at software I ask only a thing: to be simple. Embarrassingly simple. The success of Mac stuff (like ipods, macosx and so on) is based vastly on simple design of ready to use, not annoying stuff.

For this reason, the software is not anymore the focus. Core software should be open source: things like word process are not the future of the business. Things like FaceBook are the future of business.

What you try to sell is your GUI design experience (see things like FogBugz or Wordpress), your networking idea (like Facebook), your focus on search agents (like Google, because too much information is useless by definition).
