Migrating R libraries

由 ☆樱花仙子☆ 提交于 2019-11-26 23:59:35
问题 I'd like to move several R libraries (*) from one drive to another, on Linux, and would like to know whether a simple move is feasible and safe or if I should uninstall and reinstall the packages. I realize that the locations of libraries are identified via .libPaths() and have looked through the "R Installation and Administration" manual to find out about migrating libraries, but don't see a recommended process. I perceive three options: Run remove.packages() for all of the non-base packages

SSL Multilevel Subdomain Wildcard

I bought a wildcard certificate for *.example.com. Now, I have to secure *.subdomain.example.com. Is it possible to create a sub-certificate for my wildcard-certificate? If it is, how I can do this? Steffen Ullrich No, it is not possible. A wildcard inside a name only reflects a single label and the wildcard can only be leftmost. Thus *.*.example.org or www.*.example.org are not possible. And *.example.org will neither match example.org nor www.subdomain.example.org , only subdomain.example.org . But you can have multiple wildcard names inside the same certificate, that is you can have *

问题 I need to delete old and unmaintained branches from our remote repository. I\'m trying to find a way with which to list the remote branches by their last modified date, and I can\'t. Is there an easy way to list remote branches this way? 回答1: commandlinefu has 2 interesting propositions: for k in `git branch | perl -pe s/^..//`; do echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k -- | head -n 1`\\t$k; done | sort -r or: for k in `git branch | sed s/^..//`; do echo -e `git

问题 I want to delete every \"_svn\" in every folder and subfolder... For example c:\\ proyect1 _svn images _svn banner _svn buttons _svn Then I run something like rm-recurse c:\\proyect1 _svn And I should get: c:\\ proyect1 images banner buttons The ideal thing would be a tiny stand-alone EXE or something like that. -- Thanks Grant, as soon as I posted the question I saw SVN documentation about the SVN export command, but I also want to delete the _vti_* folders stuff Visual Studio creates, so I\

How SID is different from Service name in Oracle tnsnames.ora

由 蹲街弑〆低调 提交于 2019-11-26 09:05:23
问题 Why do I need two of them? When I have to use one or another? 回答1: @DAC In short: SID = the unique name of your DB, ServiceName = the alias used when connecting Not strictly true.. SID = unique name of the INSTANCE (eg the oracle process running on the machine). Oracle considers the "Database" to be the files. Service Name = alias to an INSTANCE (or many instances). The main purpose of this is if you are running a cluster, the client can say "connect me to SALES.acme.com", the DBA can on the
