Notes:
I have 19 years of experience with computers. I code on C/C++, Pascal, Perl, Ruby, Basic, Python, Java, among others...
I'm a Unix and Network hacker for... 10 years. (wow, I've never counted it!). I love to code, to play my saxophone and to sing (I'm a tenor).

I have development experience (when I say this, I mean I tested, used and developed for): Linux (my current OS), FreeBSD, OpenBSD, NetBSD, MacOS (9/X), QNX, BeOS, Solaris, IRIX (I have an O2) and Windows 95/98/NT/XP (nobody is perfect ;-)).

Currently I'm starting my own company, A&D Solucoes here in Brazil. It will be a consulting and development company. Our development department is focused on Linux/BSD solutions. Our first product, Maximus, is a 100% Linux product. Two major brazilian companies already run it :-)

Viagem para POA: Cancelada

Pois é.

Como muitos hoje em dia pelo Brasil, meu vôo foi cancelado. Cheguei ao aeroporto as 06h30 da manhã de ontem, com destino a Porto Alegre. Somente as 11h fomos informados que não iríamos mais. Complicado.

O interessante foi ver o vai e vem do aeroporto. Um vôo em particular deu pena de ver ser cancelado. TAM Curitiba -> Natal. Como disse a Aline: o pessoal já devia estar de roupa de banho por debaixo das roupas de frio e leva um balde de água fria desses. De fato.

Repórteres caçando histórias… Pessoal que devia ter chegado ontem, chegando hoje… histórias de como os aeroportos estão um caos… é isso a aviação comercial hoje no Brasil.

Mas mesmo assim, mesmo assim, quero tirar meu brevê um dia ;)

Um ótimo dia a todos!

Que ódio!

Vocês sabem o que é perder tempo precioso com besteiras? Pois é, dá uma raiva, não é mesmo?. Na nova Intranet estamos usando todas as possibilidades do PostgreSQL 8.x para gerar nossos relatórios e estatísticas. Um de nossos clientes-teste, que tem mais de 80 milhões de registros na tabela de eventos nos ligou hoje cedo dizendo que os relatórios novos estavam mais lentos que os antigos (!!).

Começamos uma investigação completa sobre o que poderia ser… e não é que as tais funções agregadas do PostgreSQL deixam o sistema mais lento? Pelo que notei, quando você faz, por exemplo:

SELECT COUNT( * ) FROM abcd WHERE data>date_part(’epoch’::text, now())

O PostgreSQL executa a função agregada em cada registro, mesmo se o conteúdo da mesma for estático, como no exemplo acima. O custo desse SELECT ficou astronômico. Mudei toda a validação de data/hora para dentro da Intranet… pelo menos 10x mais rápido.

Que ódio!!

:)
