lme, two random effects, poisson distribution
Hello, I have a dataset concerning slugs. For each slug, the number of pumps per one time slot was counted. The number of pumps follows Bi(30, p) where p is very small, thus could be approximated by Poisson dist. (# of pumps is very often = 0) The slugs were observed during 12 time slots which are correlated in time as AR(1). The time slots are divided into two categories...

Help to simulate data to model pump failure use case
Hi, I need help to simulate data to model pump's failure. Below is thought process to simulate the data: - For each Pump readings are captured via sensors each minute for period of 3 months. There are 10 pumps in total. - The failure rate or occurrences of event in 3 months for each Pump is defined. i.e Pump1 would fail 3 times in 3 months,...

Please help(urgent) - How to simulate transactional data for reliability/survival analysis
Hi friends, I haven't done such a simulation before and any help would be greatly appreciated. I need your guidance. I need to simulate end to end data for Reliability/survival analysis of a Pump ,with correlation in place, that is at 'Transactional level' or at the granularity of time-minutes, where each observation is a reading captured via Pump's sensors each minute. Once transactional data is prepared I Then need to summarise above data for reliability/ survival analysis....

pthreads with Darwine Xcode template? (or Wine Windows message pump + sockets + threads sample)
...imple pthread example will work when compiled with gcc in a Mac OSX X11 shell, but no joy with the Darwine Xcode template. I have MS Window messaging working with the Darwine template, but I need the multi-client threading piece. I suppose for pure Wine, I need a sample that has a Windows message pump and can use threads and sockets. Please advise.

RFC PATCH: bring OpenBSD stdarg in line with FreeBSD one
Having an absolute path in a #include confuses distcc''s pump mode. Since AFAICS OpenBSD''s stdarg handling uses the builtins, I think we should just treat it like we do NetBSD. I don''t have an OpenBSD box to test on, though. :( Any OpenBSD enthusiasts care to comment? Tim. diff --git a/xen/include/xen/stdarg.h b/xen/include/xen/stdarg.h...

[LLVMdev] unaligned AVX store gets split into two instructions
Hi, Yes. On Sandybridge 256-bit loads/stores are double pumped. This means that they go in one after the other in two cycles. On Haswell the memory ports are wide enough to allow a 256bit memory operation in one cycle. So, on Sandybridge we split unaligned memory operations into two 128bit parts to allow them to execute in two separate ports. This is also...

Please help(urgent) - How to simulate transactional data for reliability/survival analysis
Thanks Boris and Bret, I was successful in simulating granular/transactional data. Now I need some guidance to transform the same data in format acceptable for survival analysis i.e below format: pump_id | event_episode_no. | event(0/1) | start | stop | time_to_dropout The challenge I'm experience is to generate the 'start' and 'stop' in units of minutes/days from single column of 'Timestamp' which is the column from transactional/granular data based on condition tag...

T1 (hardware pre-shaped) shaping question
...been trying to figure this out on my own, but I guess I somewhat failed :) A linux router with external eth0 and internal eth1 acts as a gateway for a number of machines utilizing a partial T1 line (512kbps). Since the T1 is limited by hardware and by its nature to 64kbps per channel the most I can pump out of it is up+down < 512kbps. If a number of workstations amount to more than this limit the connection starts to choke e.g. delivers very low performance even on simple http requests. Right now I have HTBs installed on both eth0 and eth1. The HTB with subclasses on eth0 governs outgoing traff...

Modified rsync over SSL patch
Hi, I've been working with Casey Marshall's SSL patch, and couldn't get it to work reliably - the transfer would abort pretty quickly. So I rewrote the main data pump loop of the patch to use non-blocking IO, and am attaching the new patch. An rsync program using this patch is interoperable with the old patch. Along with the modified message pump I added the following improvements: - Buffering data to produce large SSL records (16K) to increase the encryption/...

Server w/ DHCP address incorrectly registers with WINS
...ystem is required to get its IP address via DHCP. The system is running a vanilla install of RedHat 6.1 (server option - no GUI). Issue: The WINS server has an entry for the samba system, but the registered IP address is 127.0.0.1. I suspect this is because the hosts file does not get updated by pump with the current DHCP address and the only line in the hosts file is the localhost entry. Question: How do I get nmbd to use the correct IP address when it talks to the WINS server? Hardcoding the IP address into the hosts file is not an option here. Thanks for your help, Ross -- Ross Bagley &a...

Remote Telecasts?
All -- Does anyone have experience doing remote live broadcasts over Icecast? My thought is to use a Dell laptop running Windows (yeah, I know ;-), digitize locally to 16khz, and pump the output to a remote Linux box. Has anyone done something like this before? Thoughts? Issues?

[Bridge] Out of memory problem
Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel
