IBM DB2 Express-C em versão mac

DB2 for Mac

DB2 for Mac

É oficial. A versão GRÁTIS do DB2 está disponivel para download para mac.

Acabaram-se as desculpas do não quero outra maquina virtual para correr isso, nem sequer experimento.

Eu sei que sou suspeito para falar já que faço parte da equipa DB2. A análise que vou aqui fazer é muito influenciada pelo meu dia a dia no trabalho mas o que escrevo aqui é a minha opinião pessoal .

A IBM não trabalha no DB2 para pessoas como nós que têm uns sites jeitosos com alguns milhares de hits diários (com sorte). Eles fazem isto para aguentar soluções de escala gigante, algumas com standards pesados em  XML de agências governamentais, financeiras, health-care, etc, que transaccionam quantidades enormes de informação diáriamente. Essas empresas não só tem que minar os dados como fazer queries sobre eles de uma forma bastante intensiva. Estou a falar das maiores empresas americanas, e não o digo decor. Ouvi-o da boca de DBAs da Merrill Lynch, Barclays, ONU, Morgan Stanley, etc.. Que tem eles em comum? Todos eles usam DB2 e estão interessados em usar as funcionalidades XML do produto.

Já agora ninguém confia que seja possivel ter performance em XML certo? Bem a IBM tem pessoas inteligentes (como eu, lol) a trabalhar em tornar isso possivel. Deixo este link para vos aguçar o apetite. Claro que a performance não será a mesma que SQL mas comparado com os parsers xml que andam a usar… eheh. Exprimentem. :P

Como já descrevi o cliente normal do DB2 é facil constactar que não é feito para vender a José, ao Joaquim. Nem sequer a pequena empresa da Josefina. A versão Express-C é gratís para todos por isso mesmo. As limitações são um máximo de 16Gb de ram e 4 processadores na maquina.

Se isto parece razoavel:

Depois contem como correu e se precisarem de umas dicas podem sempre entrar em contacto.

Footnote: Para os interessados se estão a desenvolver algo com um standard xml estranho  a probabilidade desse standard ser suportado pela ibm é grande e pode ser consultado aqui.

Mac OS X Leopard Tips: iSync plugin for Nokia 5300

First of all my phone sucks. I’m aware.

And when i opened iSync for the first time and saw that it wasn’t supported I was really piss*d off. I wasn’t worried about contacts – even thought it’s nice to know that if I loose my cellphone I’ll still have them – but I really needed the integration with iCal/dashboard.

I googled it and found a lot of hand-crafted solutions that I don’t think are suited the general public. Luckily someone thought of this and made a easy to install plugin to make iSync capable of synchronizing with Nokia 5300. Interested? Let’s go:

Close iSync. Download this and the unzip it to ~/Library/PhonePlugins/.

That’s it. The next time you open it you’ll be able to sync with your (not) favorite phone. Credits go to Erka, the author of this plugin.

From Ubuntu/Windows to Mac OS-X Leopard

I just got my first brand new MacBook and, as one would expect, some problems emerged by leaving my usual OS combo (Ubuntu/Windows) for Mac OS X Leopard. I’m still undecided whether to install Ubuntu or use VMWare Fusion to use Linux. As for Microsoft Windows as long as I don’t need to use .NET I don’t think I’ll install it. Not even with the free licenses Microsoft provides University of Minho students.

First I had to decide what to install:

The question you are probably asking is why Firefox instead of Safari!? Because the damn unsafe add-on for is just that:! I just can’t live without it. Maybe if the guys over there worked the basics of security we could say that it’s both excellent and safe! And don’t say there’s a add-on for Safari as well. I’ll only accept it if the add-on is as good as the one provided by Yahoo.

Now we go for the fun part. The problems and solving them. Your attention please, this is only fun for me when I do it on my computer so it won’t be pleasure if you ask me to fix your computer! Joana this one is for you, I know how your mind thinks.. Almost as badly as mine. Oh well, we are related aren’t we? :\ Please release those crazy Christmas photos to the world! :X

I’ll start with a small OS free tip and then go for the Q/A part. If you are Portuguese like myself you just hate all the results that google gives you from .br domains. Most of the results are overrated and most of the times you just wish that they weren’t there. If this is the case just do your normal search in google but write -br in the end. Just test this, go to google and type governo brasileiro -br. It works ;)

  1. How do I get my mouse to behave like a normal one by removing this dreadful acceleration?

    Easy. Check Rúben’s blog @

  2. What’s wrong with the encoding on TextEdit? The automatic descovery does not work and even when I specifically tell him to use this encoding it won’t work. The Where is ISO 8859-15 dilemma.

    Still don’t know. Anyone? If you want to test the bug just do this (from here):

    $ echo é > ~/a.txt
    $ cat ~/a.txt
    Open a.txt with TextEdit and get:

    Cracked it! At least I have a partial fix for Migrating documents from Ubuntu to Mac OS X Leopard:

    cmd + space terminal enter

    {go to the directory where the file is}

    bash$ iconv -f ISO-8859-15 -t UTF-8 {filename} > UTF8-{filename}

    For me it was:

    bash$ iconv -f ISO-8859-15 -t UTF-8 Pam.tex > UTF8-Pam.tex

    And yes PAM is as in Pluggable Authentication Modules. So I have a latex work on that :P

  3. Where is type-a-name application? It’s not on the dock.

    Just press cmd + space and type what you are looking for. This is called spotlight. Either this or open Finder and go to applications.

  4. Why doesn’t it show my dashboard when I go to the left/whatever corner?

    Have you even configured your mac? Common.. Click the apple on the top left corner and go to System Preferences. Exposé and Spaces. And now that you are there take a look around and configure all the other things that you neglected.

  5. This computer is always underlining the words in red. (when the spelling is right :P If not you are a dumbass for asking this!)

    Just press cmd + mouse and change the language. Thanks Nuno Veloso from Apple Tech Team for this tip.

  6. How can I see the right mouse button menu?

    crtl + mouseclick

  7. PageUp/PageDown!?

    fn+ up
    fn + down

If after this you still feel like reading about Mac OS for rookies – like myself – you can check this section in Arun Gupta’s Blog or check this extensive list of Keyboard Shortcuts. Have fun!

Now let’s get back to work, something almost impossible when your doing a report on LaTeX and the encodings are never right.

One final touch: ctrl + alt + cmd + 8. Merry Christmas! :)
