You can dump Linux or Unix server memory. This is useful for forensics analysis, and testing your own system. This is often desirable to see:
- What code and what data actually resides in memory.
- You can search for specific pids memory.
- Search memory for string and other data such as passwords.
- Works as add-on tool for gdb and others.
- Search/replace/dump memory from running processes and core files.
- All kinds of deep hacking activities that simply saves your time and solve problems.
Personally, I consider programming as a fundamental right. The programming will teach children problem solving and reasoning skills. So, if you have gifted kid or nephew who is about to turn 10 or 11, gift him Python for kids book. The book introduces kids to the basic concepts of Python programming. The kids require no previous programming experience. However, must understand basic math concepts.
Geany is a great and light weight cross-platform integrated development environment for Linux and Unix based systems. It supports C, C++, Java, PHP, Python and 50+ other programming languages. Geany is known to run under Linux, FreeBSD, NetBSD, OpenBSD, MacOS X, AIX v5.3, Solaris Express and Windows. Geany more closely resembles programming editors available for Microsoft Windows such as Notepad++. So if, you are switching from MS-Windows to Ubuntu/Debian/Fedora/Mint or BSD/OS X/Unix like platform try geany IDE.
The diff command compare files line by line and displays a list of changes between two file. You can use diff command to:
- See the changes between one version of a file.
- Compare two configuration or program files.
- Create a patch file which can be applied with the Linux / Unix program patch.
Say hello to colordiff
colordiff is a wrapper for diff and produces the same output as diff but with coloured syntax highlighting at the command line to improve readability. colordiff has been tested on various flavours of Linux and under OpenBSD, but should be broadly portable to other systems.
