...e how I can re-post this to Usenet groups sci.stat.consult., so they can help with this question: Exercise 1. Let Ω = {H,T,E}(a set with 3 elements, called H ,T and E . You can think of “heads”, “tails” and “edge” if you like, but this interpretation is not necessary). 1. List the elements of the powerset P (Ω) of Ω. (Recall that the powerset of a set is the set of all subsets of that set, including Ø (the empty set) and the whole set.) 2. Suppose P is a set function on Ω (that is, a rule assigning real numbers to subsets of Ω). Suppose that P({H,T}) = 3, P({H,E}) = 3, P({H}) = 1 444 Why is it im...

Hello list Does anybody know of any way to create an index of all the possible combinations of variables (factors) in a data frame? ie for 3 factors A, B & C we have A B C AB AC BC ABC which equates to columns 1, 2, 3, 1:2, (1,3), 2:3 and 1:3. I realise that a function like model.matrix does this, but how to get the seqence of the index? Any help would be greatly appreciated.

Has anyone done rollbacks with puppet? The story goes that last night I pushed a change out, which intentionally changed the way certain services where managed. The change involved pushing out a few files, cronjobs, etc., which was okay until it was discovered there was a bug with the service. My configurations are kept in subversion and rolling back to a previous configuration would have

I'd appreciate it if you'd keep on list for the archives. That said, I think this function does what you were hoping for. Michael powerset <- function(n, items = NULL){ if(!is.null(items)) { if(n != length(items)) warning("Resetting n in preference to length(items)") n = length(items) } smat <- do.call(expand.grid, rep(list(c(0,1)), n)) if(!is.null(items)) smat <- smat * mat...

I see in the changelog that: You now must specify an environment and you are required to specify the valid environments for your site. (#911) Does this mean that the puppetmaster has to be updated before clients work correctly? I ask because I''m testing out a client upgrade to 0.24.0 (server is still 0.23.2) and this is what I''m seeing: [~]% sudo /foo/bin/puppetd

I think that I''m running into the warning on external node support here but after a recent upgrade for my puppetmaster I get: puppetmasterd[19397]: Could not find aa0-006-4.foo.com with names aa0-006-4.foo.com, aa0-006-4 I''ve not changed puppetd.conf which contains: ldapnodes = true ldapserver = my.ldap.foo.com ldapbase = ou=hosts,dc=foo,dc=com I''ve not

Greetings all, My deployment of puppet includes a monitrc to make sure that puppetd stays up and running. It seems like (across all of my hosts) that pupeptd will end up dying and restarted by monit. I''m running puppetd under a screen session now on one particular host with --debug --verbose to see if any thing comes out on console but until it happens again, any anybody else

Hi, I am new to R. I have a bit of data looking like this: SemType, Length GeoLocation, Sentence GeneralInfo, Paragraphs GeneralInfo, Paragraphs GeneralInfo, Sentence GeneralInfo, Paragraphs NatLang, Phrase Advice, Article GeneralInfo Advice, Article Resource, Sentence ... (roughly 40,000 lines in total) I am interested in how many counts of each item in the second row I get for each item in

I am attempting to move our test puppet installation from looking for node information in a manifest to LDAP. I followed the instructions at: https://reductivelabs.com/trac/puppet/wiki/LdapNodes and was able to get the puppet schema loaded into our LDAP. I can now query LDAP and modify/load data without any issues using the OpenLDAP tools. e.g. ldapsearch -h ldapdev1.domain.com -x

Xapians! If tomorrow Xapian search engine would achieved the same performance and result in searches as Google we would not be able to beat Google, because we would create only a copy of the searches that already exists from Google search engine. However there is a way to beat anyone, and there is a way to beat Google successfully as well just do not give up. Some see it as implementing Ajax, or

If I have a data frame X that looks like this: A B - - 1 2 1 3 1 4 2 3 2 1 2 1 3 2 3 1 3 3 and I want to make another column which has the rank of B computed separately for each value of A. I.e. something like: A B C - - - 1 2 1 1 3 2 1 4 3 2 3 3 2 1 1 2 1 2 3 2 2 3 1 1 3 3 3 by(X, X[,1], function(x) { rank(x[,1], ties.method="random") } ) almost seems to work, but the data is not

Hi There, I''m implementing puppet for a large scale Enterprise, with a lot of sites and a lot of different setups (for about 1500 Linux and Solaris machines). Now, the time has come to get some management attention, and of course, the first question I''ll have is who else is using puppet.... So I thought it Worth''s a try to ask - who is using puppet in a large scale

hi,all I want set up a puppet HA structure. but if the puppetd can set more than one server address ,the work will be simple :D if one puppetmaster have error, the client can auto try the next. I think I can use the heartbeat or dns to do this same thing,but not so good. so I want know the puppetd can direct set in the configure file ? if not,will be add this option? -- Huang

Hi guys, I''m installing Puppet on RHEL5 systems using KickStart but struggle with the first boot. Here''s my situation: 1) kickstart installs the system, including puppet from our local repo 2) after reboot I have to login and set the hostname and IP 3) then run puppet, register it with the server and bring in the config 4) configure puppet for automatic start I have to

I just started digging into puppet and it looks like puppet is using a pull model. You have a master server and clients talk to it to get config info. Is anyone out there using a push model? If not, why not? Are there security reasons you would use one over the other? It seems that cfengine also uses a push model, so I wondered if this is a "standard" or if there are specific

I''m wondering if there is any easy way to run a command after everything else, something like: exec { when => "last" command => "/usr/local/bin/update", } Or even "run these commands in the following order", as the last step. The bottom line is that I''m trying to trigger certain behaviors after the state of the system has

With both puppet-0.23.0 and 0.23.1 if I setup just the configuration file puppet.conf, none of the puppetd options seem to get parsed. I first noticed this when monit failed to start/stop services due to the lack of a pid file being generated (and mine is not in one of the usual places). I''m sure that something like the patch attached but I bet it breaks other assumptions :-) Cheers,

I just discovered that puppet makes an assumption about which ruby ldap implementation is used. FWIW, ruby/ldap and not net/ldap is the preferred choice. Just curious, why choose on over the other? Cheers, Ryan

So one of the behaviors that seems to wedge puppetmasterd is if you re-initialize a client, the example here being that I installed an older version of puppet on a bunch of machines to test out how things work: * at some point in the past install older rev of puppet - client regiesters itself with the server, etc. - works fine. * recently, remove the old puppet in favor of a new version that
