Hi, I'm still new in linux world and CentOS is my 2nd linux desktop I ever used ( have used it for month now, before using Ubuntu for 2 days ), so please gave me a little favor on it :) What I need to do is to have my virtual console that can also run gnome or kde, so I can have different windows on different virtual console. After googling, I found the qingy that just fit for my need. I

rspec''ers I''ve committed numerous changes relating to dots, underscores, and mocks. This code will break your specs that use dots (with a couple of exceptions noted below), so you''ll have to change the dots to underscores if you''ve been using them. Feel free to check out the trunk, run it against your existing specs and report back any problems other than

I am using ms sql server and want to configure RoR such that it does not convert the given table name (example: rubyonrails) to ruby_on_rails. I set @@pluralize_table_names = false, so that it does not pluralize the table names but cannot find the config setting which will force it not to put underscore between words in a table name. thanks in advance, -- avinash -- Posted via

The Agile book mentions that using an underscore to break up words is the ''preferred'' method, but later says that you''ll have trouble using them in many-to-many association tables. What are people doing? It sounds like less of a hassle to cram my words together (cablepair vs cable_pair) and enjoy the native many-to-many handling. Or maybe I just answered my own

Hello all, I'm trying to hide files beginning with a underscore ( "_" ) and hidden files from my samba share's so i added this to my smb.conf: veto files = /_*/.*/ The section with the dot works, but the one with the underscore doesn't. I also tried /\_*/.*/ but this has the same result. Any ideas how to hide the files beginning with a underscore? Thanks, Evas

Just after R-0.63.0 came out I reported a problem to the list. I was unable to get ./configure to complete it's job, because it couldn't find a working fortran. It stopped after trying to test for underscore in subroutine names. This was especially perplexing, since I could still configure the older version (I had 62.2) with no error messages. I tried suggestions of B.D. Ripley and

Hi all, we are currently working on porting software from x86_64 to aarch64. We are working with the altarch aarch64 repos: http://mirror.centos.org/altarch/7/os/aarch64/Packages/ http://mirror.centos.org/altarch/7/extras/aarch64/Packages/ http://mirror.centos.org/altarch/7/updates/aarch64/Packages/ However, it seems that yum (and eventually rpm) has problems with identifying new packages, if

* The first patch replaces _declspec with __declspec. * The second patch replaces __wgetmainargs_ with __wgetmainargs_t and __wgetmainargs with wgetmainargs.

Hi All, So I just joined the list - first off, Markdown is a great format and we're using it in our online community project disCourse: http://discourse.ics.hawaii.edu We're using markdown for our wiki pages, stories, message postings, pretty much everywhere. One markdown policy that doesn't seem to fit intuitively for our users is the fact that embedded underscores leads to

Hi, I'm trying to document a data frame in Rd format. The data frame contains a variable called 'Health_Env'. When I create a template for the Rd file using 'prompt()' the variable name is included as-is and when I run R CMD CHECK I get a latex error because latex considers '_' a special character (used for subscripts) which is only allowed in math mode. When I

Hello, all, I'd like to propose that now that the underscore-as-assignment-operator is to be removed from R (good thing, too), that the Windows GUI should replace the underscore ``_'' with the proper assignment operator ``<-'' when you type in the underscore character. This is the current default behaviour in the ESS mode in emacs, and seems to me to be a generally good

This is a question that I should have sent to 'ess-help', but I take my chances... In 'NEWS' (1.9.0) I read the good news o Underscore '_' is now allowed in syntactically valid names, and make.names() no longer changes underscores. Very old code ... but when I try it in emacs (ESS 5.1.24), my '_' are changed to ' <- '! What can I do?

Dear R-gang, I have a question about handling underscores in names in R 1.8.1 and 1.9.0. I recently installed 1.9.0 on a machine and found that many codes no longer work as a result of the changed behavior in make.names. I have numerous data files that have dashes, periods and underscores in the header row. I've got numerous R codes that read those files with read.table and read.csv and

Hi, ESS replaces "_" by "<-". How can I switch off this feature? I need to be able to type the underscore Thanks Eryk -- Witold Eryk Wolski Heidmark str 5 D-28329 Bremen tel.: 04215261837

Hello! Hope you could help me split the strings. I have a set of strings: x<-c("name_a1_2.5.o","name_a2_2.53.o","name_a3_bla_1.o") I need to extract from each string: 1. Its unique part that comes before the last "_", i.e.: "a1","a2","a3_bla". 2. The part that comes after the last "_" and before ".o"

We have a central samba file share for our designers (who all use OSX boxes, and mostly use Macromedia products) to work off of. I've lately been able to track down a lot of application quirks (mostly problems with errors when saving, about files being locked) to the Mac resource fork files being indefinitely locked. Here's a sample from a `smbstatus` 14853 DENY_NONE 0x1
