R and computer heat
Hi, I noticed the temperature of my laptop rises sharply during execution of a long R script that generates several hundred plots, all of them saved to files. No screen output. Temps reached above 90 Celsius degrees in the box and above 80 C deg in the processor. The machine turns on cooler at maximum speed and exhaled air is really hot. Tried simila...

Regular expressions & large strings (PR#6617)
...NetBSD (1.6.1 and 1.6 respectively). Possible related (although perhaps not a bug): function(n) { line <- paste(as.character(trunc(runif(n)*100)),collapse=" ") system.time( rep <- gsub("[[:space:]]", "-", line) ) } gives rather long times rising v sharply for big strings (eg 2.2s at n=2e4, 360s at n=2e5 on AMD 1.2GHz). Other languages aren't so slow on this task (eg n=2e5: 0.4s ruby 1.8.1, and 5.2s python 2). Doubtless my extremely-quick-hack benchmarks aren't fair, but the difference still seems rather big.

Public switches (AXE10) not capable of handling sustained call setup bursts on E100P
...acant public tax office :=) 3) Each channel will continue on its own with the same proceedure: ring for 20 sec, then hangup, ring for 20 sec, and so on. Of course this leads to massive signalling on the D-channel. Result: After one or two minutes, the number of acks from the public switch dropps sharply. At the end there are only messages in one direction (from asterisk to public switch), except for some RNR (Receiver Not Ready) message from public switch. This leads of course to T200 timeouts, which very soon hits 3, and the D-channe is reset (and all calls terminated). I can not see any weird...

GSoC student application deadline
The deadline for student applications is 19:00 UTC on Friday 6th April: http://www.google-melange.com/gsoc/events/google/gsoc2012 That's just over 36 hours away as I write this. The deadline is sharply enforced by the melange software, and you won't get an extension, so don't leave it until the last few seconds, as you might have an unexpected internet outage. There's also no need to leave it so late - if you've submitted before then, you can update your application up to the dea...

Error on random forest variable importance estimates
...many variables should eventually be used? I have made successive runs, adding one variable at a time from the most to the least important (not-too-correlated) variables. I then plot the error rate (err.rate) as a function of the number of variable used. As this number increase, the error first sharply decrease, but relatively soon it reaches a plateau . I assume that the point of inflexion can be use to derive the minimum number of variable to be used. Is that a sensible approach? Is there any other suggestion? A measure of the error on "err.rate" would also here really help. Is the...

[Fwd: [Fwd: The results of iozone stress on NFS/ZFS and SF X4500 shows the very bad performance in read but good in write]]
...IHAC who would like to use Sun Fire X4500 to be the NFS server for the backend services, and would like to see the potential performance gain comparing to their existing systems. However the outputs of the I/O stress test with iozone show the mixed results as follows: * The read performance sharply degrades (almost down to 1/20, i.e from 2,000,000 down to 100,000) when the file sizes are larger than 256KBytes. * The write performance remains good (roughly 1,000,000) even with the file sizes larger than 100MBytes. The NFS/ZFS server configuraion and the test environment...

[LLVMdev] win32 assemblers and linkers for llvm
...ot;work based on project" or even "work derived from project", so the intent is to also apply the GPL license to it, even this means lawsuits. Even if right now the need for a native code generator for a *free as llvm* assembler maybe is not really perceived, I think it will arise sharply when the clang will be production ready. In that respect, if someone can adapt the MASM templates to produce NASM directives (it is the only thing that needs to be changed), these updates will be more than welcome.

TC: Simple and complex configs interplay
Hello, From a user perspective, the simple (tcpri) and complex TC configs offers two rather distinct choices. A user can very well be OK with only using the simple way and that''s very fine. Then again, even in doing so, the more complex config options are available. What is the interplay between the two as far as having some parameters configured in both at the same time ? So far

RFC: Speculative Load Hardening (a Spectre variant #1 mitigation)
...alue loaded): what guarantees that no secret info can be located on the stack or in a global variable? Or did I misunderstand the proposal? * For x86 specifically, you explain how the low 2gb and high 2gb of address space should be protected by the OS. I wonder if this +-2gb range could be reduced sharply by letting the compiler not generate 32 bit constant offsets in address calculations, but at most a much smaller constant offset? I assume limiting that may have only a very small effect on code quality – and might potentially ease the requirements on the OS? Thanks! Kristof On 23 Mar 2018, at...

Non-R question.
Hola! I have a problem which is not strictly R, although R will be used for the analysis. We have data from a large investigation of drug abuse, initially analyzed by logistic regression. But the pupils are selected by first sampling schools, and as it happens the prevalence of use varies sharply from school to school, so there is over-dispersion. Now we are interested in comparing the prevalences estimated from this study with prevalences from 3 earlier studies (93, 96, 99), which were analysed assuming no overdispersion, withouyt investigating that issue. For various reasons we can not g...

write.table() performance.
...t;scenarios". My dataset --all numeric entries-- would nicely fit into RAM and R would outperform SAS until... I wanted to export the results to a .csv file using the write.table() function. For reference, this output file was of about 30MB. Moreover, the memory needed by R would increase sharply during the writing process. I had a look at the code for the write.table() function and I found out that, basically, what it does is to create a very long text string from the data using paste() and then to print it using writeLines(). Rprof() showed that writeLines() would only use a mere 3% o...

Question regarding extrapolation
...polation of data series. It is a series of Bond yields, I am having the yield for 1 year to 30 years. I want to find the yield for 0.5 year and 30.5 years. I used the Langrange's Extrapolation but the extrapolation deviates from the normal trend ( as we can see in theoritical yield curves) very sharply, as go on increasing my years from 30 years to 35 years as well as from 1 year to 10 days(i.e. 10/365 years), on both the ends. I am having nearly 20,000 interpolated points between 1 year and 30 yrs. Can anybody help me in my extrapolating problem. I know this question is not for this list and it...

Complexity parameter in rpart

Perhaps someone can compile and reply to the list with their experiences? This looks pretty sharply written, and the fact I had success with a Java app at all is a miracle, so maybe on a different platform it works as expected. JT
