PermitUserEnvironment in sshd match block?
Hello, Our campus environment would find it very useful to pass user- environment variables for certain login ssh connections, but of course want to avoid the security problems with LD_PRELOAD and PermitUserEnvironment as described in sshd_config manpages. Would the best answer be a patch that adds PermitUserEnvironment support inside match blocks? Are there technical or other reasons

GraspeR - functions and GUI for spatial predictions written for R
Hi, I would like to announce the first version of GraspeR. It is a port of GRASP (Generalized Regression Analysis and Spatial Predictions) written for S-Plus, to R. It serves as an "automated" method for doing spatial predictions. You can find the first testing version at http://www.fivaz.ch/grasper/index.html. For now, I provide a dump file you can read with source(). A UNIX package is

Combo Box Wdget for Tcl/Tk under R
Hi, I have two questions: First, does anyone know how to put a combobox inside a GUI made with Tcl/Tk ? I think there isn't a simple way to do this (a command like tkcombobox()!), but is it possible to write a more complex code to achieve this ? Second, when I put two listboxes in the same window or frame (even in two different toplevel windows), I cannot select things in the two lists

Comparing GAM objects using ANOVA
Hi, Is it possible to compare two GAM objects created with the gam() function from the mgcv package. I use a slightly modified version of anova.glm() named anova.gam(), modified from John Fox (2002). It often gives me some aberant responses, especially with "F" test. I use a quasibinomial model and scale (dispersion) is calculated and used in the calculation of the F value. Does someone

Problemas con tildes y otros caracteres en R y RStudio
Hola. Tengo algún tipo de problema con las tildes, a la hora de trabajar en R o en RStudio, que no sé resolver. Intentando reproducir en dos PCs distintos, ambos con Windows 7, uno de los últimos ejercicios que ha publicado Carlos Gil Bellosta en su blog ( https://www.datanalytics.com/2016/06/20/6602-767-km-alrededor-de-espana-para-visitar-todas-sus-capitales-de-provincia/), me ocurre que al

Hola, Carlos. A mí también me resulta raro, porque no me pasa siempre. Es un poco aleatorio. Imagino que habrá alguna razón, y que el código de la página estará relacionado, claro, pero no consigo averiguar a qué se debe. Además las pruebas que hago me dejan todavía más perplejo.

Hola, Carlos. Pues, efectivamente, me ha ayudado. Sobre la utilización de la función geocode con ciudades con tilde, me dio Carlos Gil Bellosta anteriormente la idea de utilizar iconv para transformar la cadena de búsqueda a UTF-8, y yo lo utilicé para intentar transformar el output de html_table sin resultado: capitales <- read_html("

optim function
Hello, I want to use optim with simulated data. My program generates a sample and then calls optim to optimise a function that depends on the generated sample. I want to do this with 100 samples. But optim does not 'work' for the 100 samples, sometimes I get a message saying that sigma matrix was not invertible and therefore the optimisation was not carried out, and then my program

Debian + Samba 3.0 + Mac OS X 10.[2-3] -> insufficient privileges
hi all, I've read trough the list and see discussions with similar problems. I've setup a file server and users can connect to it via SMB/CIFS. Windows users just happy. The problem starts with the Mac users. All Mac users are using OS X (versions 10.2,10.3). I'm vetoing several files right now, permission inheriting turned on, I've forced the create mode and directory mode to

ModularIT, the GPL modular service architecture, based on CENTOS
Hi all, I'm Agust?n Benito, community Manager of ModularIT. Following the advices of the CENTOS crew that I met at FOSDEM a few days ago, I introduce ModularIT in this mailing list so the Centos community can take a look at it, since it is strongly related to this project.

Informix adapter for Ruby on Rails
We can now use Informix as back-end for our Rails applications. Here''s the code of the adapter: http://rubyforge.org/cgi-bin/viewcvs.cgi/rails-informix/?root=rails-informix It has been tested succesfully on Solaris 9/Informix 9.40/Rails 1.0.0. Since Informix doesn''t allow quoting a value for a [CB]LOB in a query, I had to override some methods of ActiveRecord::Base to accept a

I''ve just written an ActiveRecord adapter for Informix. It lacks a pair of features that I will add later, but it works for me.

Machine readable log and directory layout metadata
Hi, do you know a way/tool to save the directory layout that was synchronized to a file? So you later know there was a file "foobar" that was copied from the source to dest, and another file foobarcommon that existed in both. And know the size/mtime/hash of both. There is the log-file option, but it does not seem to be machine readable. Especially files that have line breaks in
