The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.
And an even more powerful command, creating a full tree at once (this however is a Shell extension, nothing mkdir does itself): mkdir -p tmpdir/ { trunk/sources/ { includes,docs } ,branches,tags } If one is using variables with mkdir in a bash script, POSIX `special' built-in command 'eval' would serve its purpose.
Pop 2 values from memory, add, and push result to memory; for a total of 5 data cache references. The next step up from this is a stack machine or interpreter with a single top-of-stack register. The above code then does: Load X into empty TOS register (if hardware machine) or Push TOS register to memory, Load X into TOS register (if interpreter)
The Windows Master Control Panel shortcut, labeled All Tasks in the Windows Registry and by at least one Microsoft developer, [1] and also often informally called Windows God Mode by bloggers, is a shortcut to access various control settings in Windows Vista and later operating systems, including Windows 10 and Windows 11. By creating a folder ...
Currently, Z-Push includes four backends: the IMAP and the Maildir backends for e-mail synchronization, the vCard and the CardDAV backends for contact synchronization, CalDAV for calendar synchronization, stickynotes for Sticky Notes Synchronization and one for the Kopano and Zarafa package which is sold by allowing full synchronization of E ...
The official kernel, that is the Linus git branch at the kernel.org repository, contains binary blobs released under the terms of the GNU GPLv2 license. [ 5 ] [ 10 ] Linux can also search filesystems to locate binary blobs, proprietary firmware, drivers, or other executable modules, then it can load and link them into kernel space.
In blue–green deployments, two servers are maintained: a "blue" server and a "green" server. At any given time, only one server is handling requests (e.g., being pointed to by the DNS).
It is a practical solution against any possible form of return-oriented programming. The solution eliminates all unaligned free-branch instructions (instructions like RET or CALL which attackers can use to change control flow) inside a binary executable, and protects the free-branch instructions from being used by an attacker.
