Precision of summary() when summarizing variables in a data frame
Hi,
I summary() a variable with 409908 numeric observations. The variable is
part of a data.frame. The problem is that the min and max returned by
summary() do not equal the ones returned by min() and max(). Does anybody
know why that is?
> min(data$vc)
[1] 15452
> max(data$vc)
[1] 316148
> summary(data$vc)
Min. 1st Qu. Median Mean 3rd Qu. Max.

logging location of tftpd-hpa
Hello,
On my previous TFTP server I had logging. I did see all requests in logfiles.
On my current TFTP server I have also added the options '-v -v -v',
but nog logging. At least I can't find it them in /var/log/*/*
Where does tftpd-hpa writes it's logging?

Indexing Mail faster
Hi,
I am trying to get faster search results on our webmail client(Roundcube).
Besides using Lucene for FTS are there other options?
Would having all mails indexed give fast results?
Currently the time it takes to search 25,000mails is 4mins. If indexed how
much faster are we looking at?
Really appreciate if someone could advise about this.
Thanks

Extract random part of summary nlme
Dear helpers,
I'm estimating multilevel regression models, using the lme-function
from the nlme-package. Let's say that I estimated a model and stored
it inside the object named 'model'. The summary of that model is
shown below:
Using summary(model)$tTable , I receive the following output:

"somehow" similar to the thread "under some kind oof attack" started by "MJ":
I have dovecot shielded by fail2ban which works fine.
But since a few days I see many many IPs per day knocking on
my doors with wron password and/or users. But the rate at which they are knocking

ATI Radeon 4250 in Dual Head Config?
My xorg.conf foo is pretty weak today.
Does anyone have an ATI 4250 in a dual head config? I'd be interested
in looking over your xorg.conf.

p.s. Mine at the moment, that doesn't work very well:

Show Callee name on Display
We have users with Cisco 7900 phones running sip. When user A calls
user B, we want user B's name to appear on user A's phone. It shows the
extension they call, but not the internal name of the called user. Is
this possible? We have some people that used to be on an MGCP based
system and they would get the callee's name popup on their phone when
they called someone. I

Create new data frame with conditional sums
Well, here's one way to do it:
(dat is your example data frame)
Cutoff <- seq(0, .15, .01)
Pop <- with(dat, sapply(Cutoff, \(p)sum(Totpop[Pct >= p])))
I think there must be a more efficient way to do it with cumsum(), though.
Cheers,
Bert
