MultiDatabase shard count limitations
Going back to the "prioritizing aggregated DBs" thread from
February 2020, I've got 390 Xapian shards for 130 public inboxes
I want to search against(*). There's more on the horizon (we're
expecting tens of thousands of public inboxes).
After bumping RLIMIT_NOFILE and running ->add_database a bunch,
the actual queries seem to be taking ~30s (not good :x).

Summarizing data containing data/time information (as factor)
Dear R user
I want to create a table (as below) to summarize the attached data
(Test.csv, which can be read into R by using 'read.csv(Test.csv, header=F)'
), to indicate the day that there are any data available, e.g.value=1 if
there are any data available for that day, otherwise value=0.

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi Stepan,
Sorry for the delay. It's great that you are working on MergeFunctions
as well and I agree, we should definitely try to combine our efforts to
improve MergeFunctions.
Just to give you some context, the pass (with the similar function
merging patch) is already being used in a production setting. From my
point of view, it would be better if we focus on improving its
capability

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hello Sean and Tobias,
Sean,
Thank you. Could you describe Nick's ideas in few words or give me links
to your discussion, so I could adapt my ideas to it.
Tobias,
Your patch fails on several modules in my benchmark (73 of ~1800 tests).
I have sent one as attachment.
See statistics files for more details, all the .ll files you could
simply find in test-suite object directory (after

how to output profile plots for groups using lattice package
Dear R users,
I am trying to have an xyplot of a data set which has the following
variables:
case (n=10,20,30)
parameter (parm=a,b)
group (grp=g1,g2)
y (y values)
x (x=2,4,8)
My plot should be parameter by case such that I have 2 rows (each row= each
parameter) and 3 columns (each column=each case). My R-code is as follows
but I am not able to get what I want to:

clustering fuzzy
hello,
i'm pete ,how can i order rows of matrix by max to min value?
I have a matrix of membership degrees, with 82 (i) rows and K coloumns, K
are clusters.
I need first and second largest elements of the i-th row.
for example

2 0.02 0.89 0.09 0.00
3 0.06 0.92 0.01 0.01

is this matrix symmetric
Hi,
I have this symmetric matrix, at least I think so.
col1 col2 col3
[1,] 0.20 0.05 0.06
[2,] 0.05 0.10 0.03
[3,] 0.06 0.03 0.08
or
structure(c(0.2, 0.05, 0.06, 0.05, 0.1, 0.03, 0.06, 0.03, 0.08
), .Dim = c(3L, 3L), .Dimnames = list(NULL, c("var1", "var2",
"var3")))
But isSymmetric() doesn't agree. Any comment? I am on R 2.10.1 Thanks.

Interpret List Label as Date from Quantmod getOptionChain
Hi R Helpers,
Is it possible to interpret the top level of the list as a date after downloading all the option chain data for a ticker?
For example, after I run
aapl_total<-getOptionChain("AAPL", NULL)
the top descriptor of the lists is a date (Mar.09.2018, Mar.23.2018, etc.).
So if want to subset down to those parts of the list that correspond to say, (expiration)

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one.
Here is an iostat example from a host within the same cluster, but without the RAID check running:

'splice' two data frames
Hi,
I often need to take columns from two data.frames and 'splice' them
together (alternately taking a column from the first data frame, then
from the second). For example:
x <- table(sample(letters[1:9], 100, replace=TRUE),
sample(letters[1:4], 100, replace=TRUE))
y <- prop.table(x)
splice <- function (x, y) {
z <- matrix(rep(NA, (ncol(x) * 2) * nrow(x)), nrow

2.6.33 high cpu usage
With the ATI bug I was hitting earlier fixed, only my btrfs partition
continues to show high cpu usage for some operations.
Rsync, git pull, git checkout and svn up are typicall operations which
trigger the high cpu usage.
As an example, this perf report is from using git checkout to change to
a new branch; the change needed to checkout 208 files out of about 1600

"strange" behaviour: recognition of decimal numbers by 'which'
It is a strange behaviour in that I did not expect it... but I am sure
there is a simple explanation for it and it'll have to do with the way
numbers are stored in R, but it's caught me by surprise and I don't
find it obvious.
Here's a simplified example reproducing the behaviour I encountered:
I create an empty vector, and I fill it with a sequence of numbers: 0,

Interpret List Label as Date from Quantmod getOptionChain
Package?
The **names** of the top levels of your lists, "Mar.09.2018", "Mar.23.2018"
certainly look like dates and if they are -- I have no idea what
package/context is -- they certainly could be formatted as such. See e.g.
"date-time" . There are also several package that provide date tools.
Cheers,

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec.
I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

Vintage Attrition Curves
Hi There -
New to the list, so hopefully I don't mess this up too much ... I am
hoping maybe some of you can help me. I have a problem I'm trying to
solve regarding customer accounts, attrition and forecasting.
Basically, here is what I want to do (not sure of the best way):
1. Track accounts by vintage (i.e., the month of the date of sale).
2. Forecast total accounts at a given time
