4.0 out of 5 stars Good and worthwhile, but could use some (more) editing, March 2, 2011
Verified Purchase(What's this?)
This is a solid book, well worth the purchase price and the time to read it if you want to know the kernel (particularly 2.6.30) in reasonable detail. You really should have the equivalent understanding of a bog-standard undergraduate OS theory class first, though.

It's particularly good on the issues of multi-core/multithreaded processors (which are just a special case of SMP, after all). There's basically nothing about the unique aspects of embedded Linux, though (other than a brief description of JFFS2 and a couple of other flash filesystems), so if that's what you're doing, the book is a good intro but you're going to need another book afterward.

Gripes:

The book is a bit schizophrenic in its expectations of its readers: time, pages, and grams of weight :) are wasted on quickly reiterating some basic OS theory (mutexes, standard deadlock, preemption) that should be very old hat to anybody who is going to be actually doing kernel work.

I would have appreciated more on kernel debugging philosophy and tricks, but what is there is good.

A fair number of .h files are included in their entirety. IMHO they should have been editted down to just the fields relevant to the discussion in the text; we have The Source when we need the entire .h.

It's probably more x86-centric than it really needs to be, but that's certainly a venial sin at most, since the vast majority of non-embedded Linux boxen do run x86.

Gripes notwithstanding, this book is a real service to the community. Thanks, Mr. Love.


Bosch 32612 12 Volt Compact Tough Drill/Driver
Bosch 32612 12 Volt Compact Tough Drill/Driver

5.0 out of 5 stars almost all you could ask of a 12V drill/driver, February 4, 2011
I have had this for about a decade, used for light to medium duty DIY jobs. Works very well, tons of torque for a 12V (about the same as a 14V Makita), autolocking chuck is solid and extremely easy to use, torque clutch control is quite linear, works fine in a very high dust environment, balance is excellent.

Batteries do eventually wear out, but still semi-functional after many years, including some hard use. Note: batteries seem to self-discharge much faster if you leave them plugged into the drill (leakage current?).

Only things I've seen on other small drill drivers that would have been nice to have are 1) a depth gauge; 2) an LED.
