SQL statements to get quick information about database state and get daily things done. Statements were tested on 12c Release 1 and 2 environments, but most of them also apply to 11g.

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette. See also my blog at www.janvsmachine.net.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

NodeJS

Node é single threaded, istoé, ele é incapaz de executar duas coisas ao mesmo tempo, com exceção de operaçes de IO.

Exemplos de operação não bloqueantes: Acesso à rede, acesso à arquivos etc.
Exemplos de açes bloqueantes: Loop num array, cálculos complexos etc.

Em node, o padrão é toda função assíncrona ter uma versão síncrona, por exemplo fs.readFile e fs.readFileSync.
As verses síncronas são úteis para aplicações que não dependem de concorrência, como scripts e programas de linha de comando por exemplo.
Via de regra usamos a versão assíncrona. Em uma API, por exemplo, qualquer operação bloqueante impede que novas requisiçes sejam processadas pelo servidor, por isso é importante sempre fazer chamadas não bloqueantes.

Time Travel Debugging

Time Travel refers to the ability to record a tab and later replay it ([WebReplay][wrr]). The technology is useful for local development, where you might want to:

• pause and step forwards or backwards
• pause and rewind to a prior state
• rewind to the time a console message was logged
• rewind to the time an element had a certain style or layout
• rewind to the time a network asset loaded
