Cock provides a digital version of a petcock. A petcock is a valve or faucet used to drain pressure, as from a boiler. Cock drains I/O pressure from the kernel. Without parameters, the output rate automatically adjusts; cock defers output when necessary in order to mitigate I/O spikes. Otherwise, a numeric parameter specifies megabytes per second.
getxbook is a collection of tools to download books from websites. There are tools to download from Google Books' "book preview", Amazon's "look inside the book", and Barnes and Noble's "book viewer". There is an optional GUI written in Tcl/Tk, and some shell scripts using OCR to create plain text or searchable PDFs and DjVu files from the downloaded books.
ShellCheck is a static analysis tool for shell scripts. Its goals are to point out and clarify typical beginner's syntax issues that causes a shell to give cryptic error messages, to point out and clarify typical intermediate level semantic problems that causes a shell to behave strangely and counter-intuitively, and to point out subtle caveats, corner cases, and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances.
Sar2html is a Web-based front end for performance monitoring. It converts sar binary data to graphical format. Both the command line and Web interface provide the same functionality. HPUX 11.11, 11.23, and 11.31, Redhat 3, 4, 5, and 6, Suse 8, 9, 10, and 11, and Solaris 5.9, 5.10. 5.11 are supported for performance monitoring. The reporting tool runs on Linux only. If you have customers facing performance problems on the operating systems listed above, you may send sar2ascii to collect performance data. Then you may plot performance graphics and generate performance reports in PDF format through sar2html. If you are a systems administrator, you may monitor your systems by accessing them through sar2html. Automatically collecting performance data in a predefined time window will be implemented soon.
OpenNode is a server virtualization solution that provides an easy-to-use (CentOS/RHEL based) bare-metal ISO installer that supports both OpenVZ container-based and KVM full virtualization technology on the same host. The OpenNode ISO installer will set up a minimal CentOS server system with the following features: a RHEL kernel (provided by OpenVZ project) modified to support both openvz and kvm virtualization, libvirt management interface support for openvz and kvm hypervisors, func (https://fedorahosted.org/func/) client support for central management purposes, and VM template downloads provided by the opennode TUI utility.
