    Oracle Auto increment trigger HOWTO

    Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.

    Even if  Oracle databases (<12) does not support auto increment, you can easily ask to your sql data modeler to generate for you a sequence and a trigger in a automatic way.

  • The End of the Apple Magic?

    The End of the Apple Magic?

    I have just read what Apple shown at the WWDC 2016.

    In the 1985 Windows 1.0 was born. In a snap, the IBM compatible system evolved, and the competitive advantage of the Macintosh dried up and disappeared.

    IBM PC was cheaper and way more open.

    Like in the 1985, now in the 2016 the iPhone revolution has come to an end. After the Retina Display introduction, no real new feature was introduced. The apple Watch was beaten by competition.

    Two years passed with no true innovation (i.e. Apple Watch is not a revolution).

    The last MusicApp removed the beautiful cover navigation, and try to sell you the apple music rent service all the time, instead of let me play the music I have already bought.

    If the WWDC2016 breaking news is a new file system, it is a very poor gift. I am writing this note on a Windows 10 PC. It is not a shining operating system it freeze a bit and has still a very ugly backup engine, but MacOSX is not the “most advanced operating system” anymore, like it used be in 2000.

    MacOSX is the oldest one nowadays.

    Historically Apple system are very closed. The reason is simple: when you go to your shareholders and ask for money, you can show you have a competitive advantage, a strong set of feature no one can take apart from you. But Apple lost this war in 1985, when the high pricey Macs cannot compete with open IBMs clones.

    To be fair, IBM could open to clone market because its business was on high-end server, and Microsoft alliance will help to sell more IBM PCs.

    Negli ultimi 20 anni sono successe tante cose imprevedibili. Nel 1995 nasce Java. Nello stesso periodo nasce Erlang. Java inizialmente segue la strada culturale tracciata da Sun, e si configura come un linguaggio estremamente verboso, con API specifiche per la gestione della concorrenza (es keyword synchronized per gestire nativamente le zone critiche che necessitano di mutex). Inzialmente Java è per far girare applet, poi Sun presenta un chip ad hoc (picoJava) poi IBM ci mette del suo e il linguaggio si trasforma in una ottima piattaforma per lo sviluppo server side.

    RaspberryPi 2: The perfect box for your backpack

    After my two children grow a little, I have some spare time to play with RaspberryPi. I have bought a Raspberry Pi 2 Model B, a very neat and compact machine with 1GB of RAM, and a quad-core ARM chip on it.

    I was looking for an easy-to-carry unix box, and I was wrong: raspberry pi can be a lot more than that.nippon-gio

    RaspberryPi 2 Model B SD Life Extender
    "The most dangerous phrase in the language is, We’ve always done it this way" - Grace Hopper

    I am a very happy owner of a RaspberryPi Model B 2, a quad core ARMv7  computation unit for a price between 45 and 35 €.

    If you plug only a network cable it can be powered by a USB port of your router (!avoid putting on it other USB stuff, because the energy drain can be too much).

    RaspberryPI  is a perfect all-time-running machine, just follow this smart guide…

    Erlang is a great language.

    [2019-UPDATE] Erlang 22 is OUT, so I wanna to come to the party!

    On April 2015, Erlang father’s Joe Armstrong give us a very interesting lesson I want to tell about.

    There was a long thread titled “Erlang and Akka, The Sequel” on the erlang mailing list, reasoning about the need of some standard pattern on Promises and Future. A lot of JavaScript libraries deal about that (also jQuery has its implementation). I want to report the Joe Amstrong reply because it give us a very clear understanding on the reason Erlang is different and you should at least try it once.

So let’s how to configure a perfect Debian Linux for a old wolf consultant like me. You will be able to install commercial software mubmo jumbo like Oracle Express and IBM Websphere in a snap, and have a 64 rock solid system, easy to bring in a USB stick if you like.
