Записки программиста, обо всем и ни о чем. Но, наверное, больше профессионального.

reimplement

Очень интересный и необычно многословный блогпост от Mika Raento.
Он рассматривает ситуацию, когда разработчики вынуждены добиваться кроссплатформенности, в то время как часто проще/дешевле переписать компоненты системы под конкретную платформу. Приводит очень убедительные примеры.

Facebook famously gave up on HTML5 for the iPhone. Cross-platform UI toolkits like wxWidgets, Qt or GTK are by definition doomed to the lowest common denominator (you could, in theory, reimplement the best features of each, but that's not been happening). Several attempts have been made to run Microsoft technologies on Unix (IE for UNIX, Wine and Mono), which have had mainly marginal importance - though the jury is out on Mono.

I and some friends spent pretty much all of last year trying to fit a data-heavy app into mobile HTML5. That was one of the many mistakes we made.

As a young sysadmin I settled on perl, since it ran on DOS and Linux (and later Windows). That went pretty well, but you wouldn't really build client applications with it.

But there is a big payout waiting for those who manage radical reuse.

The biggest case is HTML and javascript, especially on the desktop. Mobile HTML works for reading a newspaper, but not for building a rich client. I've recently seen people struggle with HTML and javascript on set-top-boxes, which supposedly run Webkit but in practice tie you to a very proprietary widget environment.

I find that some of the most interesting reuse is when there is a significant technological component that's being reused



Очень концентрированный текст — читать, много думать.
