X Server failing about libfreetype.so.24.0 with latest snapshot

[Thomas Schmidt]

Hi,
I just updated from a 5.7-current snapshot (15th June) to a recent one
(29th June).
Now, when I try to 'startx' I get the following error:

$ startx
xauth: (stdin):1:  bad display name turin.local:0 in add command

/usr/X11R6/bin/X: can't load library 'libfreetype.so.24.0'
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
xauth: (argv):1:  bad display name turin.local:0 in remove command

$ cat .xinitrc
cwm

Is anyone else seeing this? I'll try the next snapshot as soon as it's
available.

dmesg(8) incomplete?

[Thomas Schmidt]

Hi,
I am a pretty new user so please forgive any uninformed statements.

I just spent a few hours trying to figure out why my dmesg displays an
old kernel (May 5th), when I just compiled a new one (for recent -stable
patches). I've looked pretty much everywhere and retraced every step
until finally giving up and starting to compose a mail to get help.
Then, when pasting my dmesg output into the mail I realized that there
were multiple system messages from multiple startups in the dmesg output,
and that everything was fine with my system.
Now, except for a few threads from 200[367], even now that I know what
I'm looking for I don't see this behaviour documented anywhere. Since
there is no other record of this behaviour my knowldge is probably
incomplete but attached is a patch - I borrowed some wordings from a mail
from Theo[1] - that adds this information to the dmesg manpage.

Best Regards,
Thomas

Re: qsort.3 big O notation

[Thomas Schmidt]

In the most recent algorithms lecture I heard we used log for base 2, ln for 
base e, and lg for base 10. But asymptotically the base doesn't matter and the 
notation coventions differ. So I'd also go for consistency with other 
documentation.

 If anything, it should be log because that is the name of the
 mathematical function. libm is completely irrelevant in this context.

'lg' is also a valid name
(altough i admit i didn't know, i was used to log2)
https://en.wikipedia.org/wiki/Logarithm#Particular_bases

as Tedu pointed out lg = log2 and lg != log

but i think my point is still kind of valid,
as there is log2(3) and no lg(3).

i find it relevant that libm should also use
the most common, easiest names where possible...
it is kind of nice to be able to do 'man log2'
after reading 'man qsort', a kind of indirect
cross reference.
