Both SAX and DOM parsers attempt to download document type definitions everytime they are encountered. The caching entity resolver stores them in a local repository and answers all further requests directly from the repository.
The following code chunk is copied from my ~/.bash_profile and demonstrates how to ensure that all login shells share a single SSH agent. You will also want to distribute your public key(s) and enable agent forwarding.
Please be sure to have read and understood public key authentication. In ~/.ssh/authorized_keys a public key may be prepended by comma-separated list of options:
Are you getting sick of typing in your password each and every time you want to login to a remote host? Why don’t you use public key authentication?
PS and PDF documents are generated by so-called drivers. The name of the driver is to be specified as an option in the following notes: Figures, Colours, PDF Hyper References. The listed commands are compulsory for the given driver.
For medium to large projects, it is useful to maintain separate copies of the code to represent different stages of the development. These copies are called branches. A common approach is to have a main branch for unstable development where breakage occurs rather frequently. For each release, a separate branch is created from the main branch which is stabilized before the code is deployed. Sometimes changes need to be transferred between branches if development code needs to be included into a stable branch or if bugfixes need to be included into the development branch. This procedure is called merging.
When trying to run a graphical program under a different user than the X server, this is not permitted on a properly configured system. often xhost is used to allow the local host or a limited number of remote hosts access to the local X server. unfortunately, this mechanism does not differentiate between users and introduces a security risk because all users on such a machine are allowed to use the X server.
Have you ever wanted to remove the content of one file from the content of another file linewise? I have been in the situation several times.
Instead of first creating a tarball and then using scp to transfer it to another host, you could simply:
