...ave a matrix of dimension say 1000 * 1500 i.e. 1500 columns representing companies and 1000 rows of their returns. I need to find the correlation matrix of these 1500 companies. So I can find out the correlation as cor(returns) and expect to get 1500 * 1500 matrix. However, the process takes a tremendous time. Is there any way in expediting such a process. In reality, I may be dealing with lots of even 5000 stocks and may simulate even 100000 stock returns. Kindly guide. Vincy [[alternative HTML version deleted]]

...mize edit/compile/debug turn time, is there a way to compile llvm tools so that the majority of the files are compiled as if for release (eg, no debug symbols), and only the handful of files that I have touched are compiled for debugging? This will reduce the load on the file system, linker and gdb tremendously. At present, AFAICT, it's all or nothing. -------------- next part -------------- An HTML attachment was scrubbed...

I''ve just released Juggernaut - a plugin for ruby on rails. Check out the site: http://juggernaut.rubyforge.org I?ve also finished a demo that illustrates some of Juggernuat?s capabilities. You can sign up for an account here: http://alexmaccaw.no-ip.info:3500/login/sign_up . It might be a tad slow as it?s running from my home machine. Juggernaut for Ruby on Rails initiates a flash

Let me firstly thank the R Core Team for their tremendous efforts in providing R 1.8.0. My following comment should therefore be understood as an "fyi-only". I source compiled R 1.8.0 for windows with ATLAS (source compiled, too). Everything works fine and R is running flawlessly! However, running "make check" stops during processi...

Dear rsync devs, I recently concluded a bug hunt to trace why my rsync-ing to an SBC was much slower than the corresponding iperf3-reported speeds. To give a concise summary of the situation, in slow wifi links using SSH with ProxyCommand tremendously speeds up things: $ dd if=/dev/urandom bs=1M count=50 of=sample.data 50+0 records in 50+0 records out 52428800 bytes (52 MB, 50 MiB) copied, 0.24135 s, 217 MB/s $ rsync -avz --progress ./sample.data root at 192.168.1.150:/dev/shm/ sending incremental file list sam...

I heard about some inexpensive security cameras which get their power through the same cat5 cable which delivers the data/pictures (which would simplify wiring tremendously). Does anyone know about these? Do they work with Linux, particularly CentOS? tnx 4 tips.

...e Nagios up and monitoring every thing hangs. Even a terminal will hang before it finally just locks up. The only thing that brings it back is a reboot. Even stopping the services doesn't work. Disk space seems fine and even during the hangs there doesn't seems to be anything taking up a tremendous amount of resources. After a reboot every thing works fine for several hours.

...lution? It seems to be pretty powerful, if a bit finickety to set up initially. The way we currently do backups is to use rsync from the clients to two folders on an older server that rolls over every other week. This worked fine for a while, but the rsync is cumulative and the users generate a tremendous amount of data every day after having had a client upgrade with newer and hilariously fast computers for calculation. The previous *nix-admin set it up this way with rsync, meaning that we in the long run have data that is way obsolete and get increasingly difficult to maintain. As the bac...

dear helpers, I wonder if there is a way to read a molecular dynamic trajectory file ( binary file) produced by CHARMM into R. Something like that in matlab. Actually this will save tremendous effort in post processing. best regards karim

I want TableGen to be able to infer lots of stuff programmatically. This helps tremendously when specifying things like, oh, AVX. :) We could invent our own pattern matching syntax, but why? -Dave

Hi, It looks like the DeadStoreElimination optimization doesn't work across BasicBlock boundaries. The project I'm working on (https://github.com/trailofbits/mcsema), would tremendously benefit from even simple cross-block DSE. There was a patch to do non-local DSE few years ago (http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-January/028751.html), but seems that the patch was never merged. Is there an existing way to do cross-block DSE? Was there something wrong with the...

Hi, I tried to upgrade from Samba 2.2.8a to 3.0. It worked generally speaking fine and speed went up tremendously, BUT since then the DOS conversion of long file names is freaking me out. Using long file names produced a readable short version plus ~1 oder ~x. where x stands for a number. now long file names produce some cryptic 8 letter name plus extension. listing in a DOS box additionally shows t...

...other was recorded with a standalone camera. This means that you can't see the speakers in one room, which is unfortunate but much better than no video :). I want to send a huge thanks to Jason Molenda. Not only did he contribute his equipment to record the event, he also collected a tremendous amount of the content, edited the videos, transcoded them and did a lot of other great work. Getting nice videos up takes a lot more work than it seems, and the video quality is very high this year. Thank you Jason! -Chris

...does anyone know of a SIP phone with a built in VPN client that can provide the tunnel for *both the phone and the pc traffic*? It would seem trivial to route a subnet down to the vpn client in the phone, that would be available to devices connected on the PC side of the telephone.. This would be tremendous for an at-home contact center agent.. An added benefit would be to limit connections the connection on the PC side of the phone to a specific mac address.. We're aware of the opportunity to use a softphone on the pc with a vpn client. though, we're looking for a physical phone. ---...

Just got a call from a company in Warren, MI . They recently had an Asterisk system put in by a vendor, and are having issues which need analysis and correction. They have a tremendous sense of urgency. They have about (40) users, and need DID's assigned to extensions and are having some echo issues at the site. If anyone is in the Warren, MI area, and is interested in some cavalry work, shoot me an email. Thanks, Cory Andrews Executive Vice President +++++++++...

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options:
