I have an ActiveRecord object fetched from the database, and I need to evaluate the contents of the updated_on field. However, *any* attempt to access that data in the program results in a TypeError with the message ''no implicit conversion from nil to integer''. cust =

Dear All, I am a researcher doing research in plant growth and I have a statistical problem that seems to not be able to handle. Recently, I conducted an experiment about plant growing in three different nutrient-level sediments. I harvested these every three week (three harvests in all). Some growth traits of these plants were recorded (e.g. total biomass, leaf biomass and stem biomass). In

Hello. I need to plot a two-way interaction (5 levels X 3) with error bars. The x.factor will be the five-levels var and the trace.factor will be the three level var. I was able to find functions that draw error bars, but still couldn't find a way to draw an interaction plot that looks like what is common in psychological (and related) journals: the lines (three in my need) are plotted in

I installed Ubuntu Feisty successfully, then I configured the network (static IP) and things worked well. Then I installed Xen using "apt-get install ubuntu-xen-desktop". I could boot the xen kernel, and booted succesfully to dom0, however, there''s no network for dom0. According to network manager, I saw that Ubuntu recognizes now 4 unconfigured adapters (veth0, veth1, veth2,

Hi All, I'm running netbench against our samba based filer and having I believe a controller problem. When I configure the test to run multiple engines per client (about 5 in my case) and about 20 clients so all together I have 100 engines, the controller crashes. My clients are a mix of NT4, winxp and win2000 systems. If I run the controller on windows 2003, the controller simply

Hi All, Is it a way to prevent joining a domain with a netbios name that already used by other domain member?. For example, if I have SAMBA server "SA1" already joined a domain and then I go to a different SAMBA server and make it join the same domain with the name "SA1" also. What I found out is that the domain controller does not care and it will let me join the

The difference between groups is in the order of manipulations: group.CD having first a block of present.type.C and then a block of present.type.D, each block containing 31 trials. group.DC having first a block of present.type.D and then a block of present.type.C,

Hi all, I have noticed that if you create a share to path lets say \\dir1\dir2\dir3 And a user lets say u1 has full control on dir3 BUT no control at all on dir2 then user u1 cannot access the share. Is it right? We have a situation with clients who typically do the following: Create a share to the root of the file system and give only to administrator full control on for the root path

A file in a NT filesystem can have multiple

Hi All, As it is written in the "Linux 2.4 Advanced Routing HOWTO" GRE tunneling has some benefits compare to IP-in-IP, on of it benefits is the ability to transport multicast traffic through a GRE tunnel. I used the mrouted daemon and I know that the daemon supports tunneling but I don''t want to use its tunneling method. Assuming I have gre0 as my tunneling device I did the
