Click the Notes tab to see what I talked about on each slide. These are slides from my Ignite Velocity talk. "ignite" means 20 slides changing automatically after 15 seconds, total of 5 minutes talk. For slideshare, I've expanded the transitions into slides so the slide count is more than 20.
This talk is about easy ways to reduce image sizes without compromising quality using open-source command-line tools you can easily automate. About 50% of the average web page is images, so by focusing on images, you have an excellent opportunity to improve page performance and user experience. You can save 20-30% of your bandwidth bill and improve response time with little or no code changes and your site will still look just as good.
Topics discussed:
* GIF vs PNG
* PNG8
* Truecolor PNG
* IE6 and transparency
* AlphaImageLoader and performance
* Optimizing PHP/GD-generated images, favicons, CSS sprites
Este trabalho cita alguns exemplos de métricas e por que usá-las em projetos de software. inclui também sugestões de ferramentas que auxiliam na coleta de informações de métricas de código.
