Family PC Windows / Linux Dual Boot Setup

Poor Man's SteadyState (or DeepFreeze or ReturnNil or ...)

This is the configuration I have used to set up home PCs to be resistant to the kinds of bugs and malware and spyware that seem to get installed over time on a windows PC. This is in combination with using limited accounts for everyone who uses the PC.

The quick overview is:

Por que no Brasil software livre ainda é visto como coisa de pobre que não pode comprar software proprietário?

Por que no Brasil software livre ainda é visto como coisa de pobre que não pode comprar software proprietário?

extraído de um fórum de internet

  1. Os usuários das distros e comunidades insistem que devemos aprender a usar o terminal.
  2. Os programas livres em sua maioria não fazem a metade das coisas que os proprietários fazem.
    • Gimp não suporta canais de 16 e 32 bits de cores até hoje. Só importa imagens assim, mas não pode salvar.
    • Colocar a imagem que está em uma camada superior em modo overlay ou qualquer outro modo para fazer efeito na imagem da camada inferior não funciona.
  • Inkscape não é tão simples como se imagina. Não possui malha interativa (mesh) e, em máquinas mais modestas, se seu trabalho tiver muitos vetores, não rola.

Complete overview of the PHP SessionHandler life-cycle

This page provides a full overview of PHP's SessionHandler life-cycle - this was generated by a set of test-scripts, in order to provide an exact overview of when and what you can expect will be called in your custom SessionHandler implementation.

Each example is a separate script being run by a client with cookies enabled.

To the left, you can see the function being called in your script, and to the right, you can see the resulting calls being made to a custom session-handler registed using session_set_save_handler().
