Hello, I'm trying to compile vmkit on a x86_64 linux box with gcc-4.1.2, but I'm running into troubles because of various problems with casts between pointers and integers. Is there anybody who succeeded in this task? Az I see, some of the problems can be fixed with an appropriate typedef/macro declaration, but in VMCore/JavaObject.cpp some lowlevel bitmanipulation is used, to mark

Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like

Hi! There''s something I don''t understand yet about static/private methods. I hope someone can explain...

Hi mongrel-herders, I''m just wondering what fellow railsers use to rotate their logs in an orderly fashion? I''d like to do something lightweight, i.e. (1) rename the logfile (2, optional) create a new empty logfile and (3) send a signal to each mongrel in the cluster and have them understand it''s time to reopen their log file handles. This is what I do with apache and

Hi Zsombor, Thanks for the patch! Unfortunately I can't apply it because the llvm API has moved from BinaryOperator::create to BinaryOperator::Create. Are you using svn head? Now on the x86_64 part. There has been very little work on porting vmkit on x86_64. If you're having compilation problems, I suppose it's in the garbage collector directory (GCMmap2). If you could make the

Hello, I''m trying to restart my application fastcgi processes using reaper. But I get the following error: $sudo -u www ./script/process/reaper Couldn''t find any process matching: /var/www/example/200605200000/public/dispatch.fcgi The problem is that it should not look for 20060520000 but for current which is a symbolic link pointing to 200605200000.

Hi. I am using Capistrano for my webapp and after deploy I need to restart memcached service. I am trying to do it with sudo "/etc/init.d/memcached restart" But it does not do it, even if memcached service existed - after deployment memcached service is off.

Dear all, Being an economics student, I am trying to put together a little tutorial/FAQ/... for those who have (more) background in econometrics rather than in statistics -- just as I have. I'v been looking for a hypothesis testing tool in R (just linear or also nonlinear) for model parameters, but could not find anything so far. I did find a similar but unanswered question in the archives,

Hi, I am new to R, but a fairly `old' user of Stata. I read posts asking about survey methods and large datasets in the archive, so I will not ask those questions again. But some still remain: - R seems to consume more memory given the same set of data, say if I have only a data frame defined, than Stata. Am I right if I think that this is because the object oriented nature of R and can
