Good books on the current design and architecture of Linux
by JD
Does anyone have an inside scoop on books that look at the
detailed design and architecture of a recent version of
the Linux kernel?
Some that I have seen are rather dated - from early to
mid 90's.
Some links to such "recent" books would be appreciated.
Google is returning way too many links and very hard
to sift through.
Thanx.

Replacing laptop cpu
by JD
I have an HP laptop with
AMD Turion II X2 mobile processor RM-72 / 2.1 GHz CPU, Socket S1.
It is now causing blue screens in windows and freezes
linux (pclinuxos, knoppix, fedora live).
I have run the x86 mem test for more than a day, and
found no problems with the 4GB ram (2GB X 2).
I am wondering why the memtest does not freeze????
could it be that only one core is causing the problem?
At any rate I wanted to replace it with
AMD Turion II Ultra M660 TMM660DBO23GQ 2.7GHz Dual-Core Mobile CPU
Processor, Socket S1
Will I be running into any problems?
Would the heat be an issue?
These are the full technical data on it:

f22 nautilus icon view HUGE!
by SternData
How do I set the default view sizes for nautilus? The icons are huge
and the list view is spaced with dividing lines. I can click a button on
the toolbar and move the slider to the left, but it doesn't stay slid
across sessions.
I don't see any way to set preferences.

Is there any way to go back to 21?
by David Cary Hart
I am having all sorts of ugly problems, particularly with T-Bird. Also
22 mounts my phone but refuses to mount my Kindle. KDE lost a bunch of
widgets including weather and ktorrent. 21 was more stable, possibly
faster. This is the first major upgrade problem I have had since FC9.

The Google contacts issue
by David Cary Hart
Can someone more technically proficient than I explain where the error
is occurring? I need enough information to file a bug report - somewhere.
I do know that it is not a Thunderbird issue because the exact same
thing happens in Evolution. Moreover, the problem does not extend to
Google calendars which sync just fine.

Fedora Project Leader "Ask Me Anything" tomorrow.
by Matthew Miller
Hey everyone. I'm going to do an "Ask Me Anything" session in
Reddit's "r/linux"* tomorrow (Thursday, May 28) starting in the morning
my time (east coast US) and going until... we're all tired and bored, I
guess.
Of course, I hope that people know that you can pretty much ask me
anything at any point (like, on this list), but in this case I'm making
a formal thing of it. — hope to see you there!

ssh-server problem after upgrading 21->22
by Jouk Jansen
Hi all,
Today I upgraded one of my machine from F21 to F22. After the upgrade I
cannot connect anymore to this machine using my OpenVMS system by means of
ssh. Looks like there is an cipher mismatch. How can I configre my sshd on
F22 to make it work again? (see logs for F22 & F21 below)
On the OpenVMS machine I see:
