Dear R experts, I have a folder names "200209" and in this folder there are many data files, such as: "BA020902.txt","BA020903.txt","BA020904.txt", "BA020905.txt","BA020906.txt","BA020909.txt", "BA020910.txt","BA020911.txt","BA020912.txt",

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways. For example, I do not want to save the comment if there is no comment or upload. Or, I do not want to save the comment if the image has been uploaded previously (comparing md5s with past upload md5s

Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value.

I am about to lease another server to be a backup web/mail server with a replicated mysql database. The current live server is a dual Xeon 2.8Ghz. Would I do better to get another Xeon server or an Opteron based server? My concerns are compatibility of the database and the SSL certificate currently running on the Xeon machine. Are these concerns unfounded? TIA Mike

Hi all, I've setup samba4 according to the samba4 wiki on centOS 5.4 in KVM. This went without any problems. I only had to install a higher version of bind to 9.6.x because Centos bind in repo will install version 9.3.x. I've used the Fedora12 source rpms for this to build bind 9.6.x on Centos 5.4. Then I configured bind according to the samba wiki

Yes please for the notes. I re-ran the tests without the smbldap-tools. I installed phpldapadmin and am able to login to the apache page using the cn=admin, dn=mydomain and create entries. This kind of tells me that LDAP is working Then I run the pdbedit -Lv and it lists all the users.

If you do this howto right now you will start with samba4 alpha13. You do not need the update section. But you need git for your installation because the rsync-thing is broken!!!!!! First of all do not install the bind
