search for: speedbumps

I think you can simplify a little by replacing this: pkg %in% loadedNamespaces() with this: .getNamespace(pkg) Whereas getNamespace(pkg) will load the package if it's not already loaded, calling .getNamespace(pkg) (note the leading dot) won't load the package. I can't speak to whether there are any pitfalls in changing the library path searching, though. -Winston On Thu, Jan

Hi all, Profiling turned up a bit of a speedbump in the library function. I submitted a patch to the R bug tracker as bug 16168 and I've also included it below. The alternate code is simpler and easier to read/maintain, I believe. Any thoughts on other ways to write this?

A isNamespaceLoaded() function would be a useful thing to have in general if we are interested in readable code. An efficient implementation would be just a bonus.

isLoadedNamespace() sounds fine to me..

Speedbumps make sense sometimes, An attacker getting root on the jumphost gets immediate control of any _current_ persistent connections and new connections. Without ControlMaster it's a _lot_ harder to take control of current connections, but pretty easy to subvert new connections. So there is a benef...

Dear Mailing List We are using a ControlMaster with a short ControlPersist to access the bastion host which then gives access to customer hosts. Our Information Security Manager would like to disallow the ControlMaster. His attack scenario is an admin workstation with a compromised root account. An attacker can then use the ControlMaster to trivially get shell access on the bastion host

Hi, I''m working on a pretty typical social networking app. It takes a little data from the authentication/session objects that I''ve sort-of got working, a little data from this table and a little data from that table to make up the main page. Seems like a pretty common design, not so different from what yelp or tribe do, although much simpler (for now, anyway). What I

Hi all, I have been having a bit of trouble setting up my Samba 3-OpenLDAP PDC...This is something totally new to me (no previous Samba experience at all). I've had several speedbumps, but I've finally got my setup almost complete. I can join computers to the domain, however, if I try to logon with a user, I get the above error from Windows. I can logon as a Domain Administrator, but if the user is a member of any other group, they cannot login. I have setup my machi...

I just made a rails application that I plan to sell and dsitribute. I want to distribute it without having to worry about someone stealing the code and selling their own version. How do I do this? Is there a ruby obfuscator or anything that can keep someone from seeing the code? Thanks for your help. -- Posted via http://www.ruby-forum.com/.
