I've seen its description (at http://www.freelabs.com/~whitis/unleashed/ ) and it seems a good introduction for general programming on Unixes if you're not yet used to it, but it won't add much in respect for low level programming. A book dedicated assembly would do that for you. I've search more and found that "The Art of Assembly Language" would be an excellent choice. It's also available online: http://webster.cs.ucr.edu/Page_AoALinux/HTML/AoATOC.html or http://webster.cs.ucr.edu/Page_asm/ArtOfAsm.html for other formats. Mandatory chapters would be: 1.2 The Basic System Components 6.6 Virtual Memory, Protection, and Paging 6.8 NUMA and Peripheral Devices 7 The I/O Subsystem Especially the 7th. But if you like the subject take a look to the rest too. It's not infrequent one has to write a little of assembly to squeeze the last bit of performance on a driver.

I always enjoyed much more a good hypertext document. ------------------------------------------------------- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.
