    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.

    I am smarter syndrome

    Sometimes in University I found bold young guy saying something like:

    I will reimplement this in machine language because is faster

    I will reimplement this xyz C function by my own

    My program crash, I think there is a bug in HP UNIX socket implementation

    I will ge rid of this Java Garbage Collector because it is too slow. I will reimplement all the code in my C++ routine.

     

    Belive me: your code is doomed. A full list of guys have already done your same code, found a million bugs and corrected it in the tool you want to replace because they are shitty slow, to your eyes.

    I feel your pain because I made your same mistake. Keep reading.

    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.

    Traditionally Lego bricks cost a lot. This guide will try to give you some guidelines on “brick best price”. First of all basic creative box seems the cheapest one. For instance the LEGO 10702 - Classic Set Creativo has 583 pieces for less then 25 € on Amazon. The cost per brick is about 4.25 € every 100 bricks.

    1. A dump of the Lego set database. It is from 2014, but it could be a good starting point for your own database needs
    2. A stocking and stackable lego strategy
    3. A web site to know what else you can build with your pieces.
    4. A replacement part site with manual download too.
      1. By the way search 10188 for death stars replacement (red/blue swords!)
      2. 10179 for millenium falcon

    Tonight I stubled upon PropEr, a Property based testing tool for Erlang. It seems a very smart idea: instead of writing a single unit test, you write a set of properties your code must satisfy.
