Comparison of Distributed File System Features
Humpa, Vítězslav ; Kašpárek, Tomáš (referee) ; Szőke, Igor (advisor)
The goal of this thesis is to compare parallel ditributed file systems. Thesis aims at GlusterFS, PVFS 2 and Gfarm FS. There is a description of each filesystem's theory, including general installation and configuration information. The text also informs about experimental work done with each system and evaluates test results which are then used to determine ways of filesystems' possible usage at our faculty. All tested filesystems have shown to be stable enough for use in one of the applications on FIT. As it's described in this thesis, GlusterFS would excel at applications that require simultaneous access to many large files (i.e. recorded lectures download system), all filesystems would give roughly the same performance when accessing many small files (i.e. webserver) and PVFS2 and Gfarm FS would be better suited for work with small number of large files (i.e. some distributed calculations).

REmail - Integrating e-mail Communication in the Eclipse IDE
Humpa, Vítězslav ; Šuška, Boris (referee) ; Hruška, Tomáš (advisor)
Developers of software systems have to communicate about the project they are building. Especially when working in a distributed development team, such as open source projects, developers must use an asynchronous means of communication. Studies tell us that e-mails are, by far, the means of communication mostly used during the distributed development, opposed to instant messaging, commit comments, or code comments. Therefore, we can imagine archives containing development e-mails enclose essential information concerning various entities of the source code. Unfortunately, such information gets lost with time, since relevant e-mails are hard to retrieve. We have developed REmail, an Eclipse plug-in, to integrate e-mail communication in the IDE. It allows developers to seamlessly handle source code entities and e-mails concerning the source code, without ever exiting from the IDE. Using lightweight linking techniques, REmail retrieves all the e-mails relevant to the chosen source code entities and makes them available to the developer.
