Poseidon Linux is based on Ubuntu, so instead of using /etc/inittab and getting a run level, Upstart is event-driven, meaning that certain processes start when a condition is met or triggered.

			Some major programs that are run include acpid.conf, cron.conf, dbus.conf, hostname.conf, hwclock.conf, network-manager.conf, and udev.conf.

	Poseidon Linux follows the usual Linux startup, where the BIOS is the first thing running. The BIOS (basic input/output system) checks to see if the hardware and peripherals of the computer are functioning together, and also loads the Master Boot Record, which is the first 512 bytes of a data storage device that stores the boot record of an operating system. The MBR then starts the boot loader, which is a program that loads the operating system. In the case of Poseidon Linux, the boot loader is GRUB. GRUB then loads the operating system. Once it is loaded, the kernel calls Upstart, which is a replacement for the older System V init. This is because Poseidon Linux is based on Ubuntu, and Ubuntu has used Upstart since the release of Ubuntu 6.10.

	Due to the subject specialization of most of the programs and the knowledge required to use them to their respective potentials as intended, I’m unable to adequately review the programs and give a detailed analysis of how useful or well made these programs are ''(see fig. 1)''. In retrospect, it was unwise to choose a distribution based on coolest sounding name rather than practical usage. Aside from the inherent complexity of many of the programs that came with Poseidon, many of the listed programs simply do not execute when selected. The most noticeable disappointment among the inactive/broken/not-yet-implemented programs was the OpenUniverse Space Simulator, which by merit of name alone was obviously intended to be the high point of Poseidon’s entire existence ''(see fig. 2)''. Other non functioning programs include Stellarium, presumably another failed space simulator, and PyMol Molecular Graphics System, a program listed under Bioinformatics. Aside from the programs targeting Poseidon’s main audience, there are programming IDEs like Eclipse and QT Creator, audio/video/image editing programs like Audacity, Pitivi Video Editor, and GIMP, office applications that include an assortment of LibreOffice programs, and 3d graphics modeling programs like Blender.

	The first working program I tested was GPeriodic, which is a periodic table of the elements that allows the user to select any element on the table to view more detailed information about it. The reason I chose GPeriodic as one of the programs to test was to see how many features it had, in order to get a feel of how in depth the programs provided by Poseidon are. GPeriodic proved to be full of information pertaining to each element, organized in an ordered and easily accessible manner. Such a program is of obvious value to anyone who is using Poseidon for scientific purposes, particularly those doing chemistry. The second program I tested was called fityk, a data analysis program with a ~~poorly~~ chosen name. Since it claimed to do data analysis and had numbers everywhere, I figured it was legit. It also allows the user to select from a long list of function types, from quadratic to exponential decay. After this, the rest of the programs under Applications => Poseidon become even more obscure and complicated, though of no fault of its own considering that Poseidon is advertised to have a rather specific purpose, geared toward the scientific community.

It also allows the user to select from a long list of function types, from quadratic to exponential decay. My reason for choosing to test fityk was that it was one of the few remaining programs that seemed to be reasonably understandable without needing too much prerequisite knowledge. After this, the rest of the programs under Applications => Poseidon become even more obscure and complicated, though of no fault of its own considering that Poseidon is advertised to have a rather specific purpose, geared toward the scientific community.
