fio is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 13 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more. It can work on block devices as well as files. fio accepts job descriptions in a simple-to-understand text format. Several example job files are included. fio displays all sorts of I/O performance information, including complete IO latencies and percentiles. Fio is in wide use in many places, for both benchmarking, QA, and verification purposes. It supports Linux, FreeBSD, NetBSD, OS X, OpenSolaris, AIX, HP-UX, and Windows.
Enrollix manages enrollment of people to associations, communities, groups, classes, teams, magazines, and events like meetings, parties, etc. It collects detailed personal data of members and of their enrollments (with a possible fee), selects them according to any kind of filter, and produces a balance of the revenues which can be saved in a CSV (comma separated value) file. This file can be opened with a spreadsheet like Calc or Excel. It is possible to prepare different models of certificates (like a receipt or a certificate of membership) within the software and print them with the data of any member, with a possible progressive number (like a protocol) within it. It can print labels of addresses or lists of payments of the selected (filtered) members, and it's possible to save their postal addresses or all their personal data in a CSV file, or to copy their email addresses to the clipboard, to paste them into the recipient field of a new message. The personal data of each member may contain a picture, which is saved in a directory with the same name and path of the file in use. It is possible to export selected members from the file in use to another Enrollix file, or to import all the members from it. Each member and his or her enrollments are internally identified by a unique mark (a UID number).
