Main characters

Grim Reaper

Voiced by Greg Eagles

Grim is over one hundred and thirty-seven thousand years old (as had been born at the time of the Stone Age) and speaks using a Jamaican accent. The continuity of how Grim got his reaper status and tremendously strong and powerful supernatural powers comes up quite a few times and it is unknown which way he really got his supernatural powers (for example, in The Wrath of the Spider Queen movie, he was elected to his position as the Grim Reaper while he was in middle school; however, in A Grim Prophecy, it is shown that he was the Grim Reaper since his childhood with his parents forcing him to be the Reaper, which is further contradicted in a later episode where he is seen stumbling over his scythe to become Grim Reaper). His long scythe is the source of all of his supernatural and magical abilities, and possesses many magical capabilities and qualities; although he is still capable of using some incredibly powerful magic spells without it, though these instances are quite rare.

H2O (software)

H2O is open-source software for big-data analysis. It is produced by the start-up H2O.ai (formerly 0xdata), which launched in 2011 in Silicon Valley. The speed and flexibility of H2O allow users to fit hundreds or thousands of potential models as part of discovering patterns in data. With H2O, users can throw models at data to find usable information, allowing H2O to discover patterns. Using H2O, Cisco estimates each month 20 thousand models of its customers' propensities to buy.

H2O's mathematical core is developed with the leadership of Arno Candel; after H2O was rated as the best "open-source Java machine learning project" by GitHub's programming members, Candel was named to the first class of "Big Data All Stars" by Fortune in 2014. The firm's scientific advisors are experts on statistical learning theory and mathematical optimization.

The H2O software runs can be called from the statistical package R and other environments. It is used for exploring and analyzing datasets held in cloud computing systems and in the Apache Hadoop Distributed File System as well as in the conventional operating-systems Linux, Mac OS, and Microsoft Windows. The H2O software is written in Java, Python, and R. Its graphical-user interface is compatible with four popular browsers: Chrome, Safari, Firefox, and Internet Explorer.
