Net Transport Training Area :: Tutorials

 

By my personal opinion, there has been a better office applications package than Microsoft Office, back at 1995. It name is Lotus SmartSuite. By my opinion Adobe Illustrator is far better than Corel DRAW! Adobe Illustrator has possibilities, tools and features so advanced, that Corel should have no chance at market.

Microsoft shows the people how they product could be used in real life. How they can help to solve their troubles and improve everyday routine. It has not been interesting about what users want, but what they really need. And done priceless research on this field. Corel DRAW! is distributed with a few thousands cliparts and hundreds of fonts - everything ready to use, just put some pieces together (no matter that it looks like pure pseudoart) and save them as a new clipart.

By my personal opinion, these strategy (and tactic) decided about winners.

By my personal opinion, Net Transport is presently one of the best download manager. It is powerful tool on internet and it has a lot of abilities. But the best of all on it, is "user-friendly" look and work. Very rare combination at tools which can be used by professional also. This is the most symphatic to me. It is not that kind of tools, as e.g. Austin-Martin car is: it even does not try to put on the apperance of "car for everyone".

I remember, how proud I was, when I have been able not only to find an compiller error OI4498A 1225:0016 in a few hundreds pages manual, but even, I have been able to understand its description! It was not long ago - at early 80's last century. The best game with comuter has been to give your name into text editor command line and guess what will be the result. "Gah, remembrances are tyrans!"

Hope, these short tutorials presented here, help you to unleashed Net Transport abbilities and use it on scale it deserves.

This is the only one official document - W3C agrred with this at RFC3232 where it allows to refuse previous RFC1700.

Streamed media downloading forum: http://pub25.ezboard.com/fstreemeboxvcrfrm5 - is forum moderated by Veblin with a few others contributors. It is concerned on streamed media. Mainly on downloading them, but there are also a few specialized tutorials for grabbing URIs and converting streamed media to something more friendly for handle. Forum could migrate from time to time, look for "streemebox" (with double "e").
Definitelly worth to browse through-out: you should start with tools section (there are links to all tools I mention in my tutorials), then continue through tutorials, hints and FAQs section and finally through adult-link forums - this kind of industry is the less conservative and is able to hire a real professional programmist - so their links are very hard to be found and downloaded. You probably find there a solution for most of problems you can encounter.
