- librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
- PEBL is:
- Free psychology software for creating experiments
- Allows you to design your own experiments or use ready-made ones
- Lets you exchange experiments freely without license or charge
PEBL offers a simple programming language tailor-made for creating and conducting many standard experiments.
- PSPP is a program for statistical analysis of sampled data. It is a free software replacement for IBM SPSS.
It is a powerfull tool which can be used for exploratory data analysis, hypothesis testing, data preprocessing and visualisation. Available procedures include t-test, anova, linear and logistic regression, non-parametric tests, factor analysis, principle components analysis, cluster analysis, receiver operating characteristic and many more.
It can be used either with a command line or graphical user interface.
- SalStat is an small application for the statistical analysis of scientific data (with a special concentration on psychology). It can already do 18 kinds of descriptive statistics, t tests (paired, unpaired and one sample), 3 kinds of correlations linear regression and point biserial tests, and single factor anova (both within and between subjects). Data is entered on an easy-to-use datagrid like a spreadsheet, and all the analyses are driven by menus and dialog boxes. Output can be formatted to HTML.
- Terminal Matrix 8086
- Terminal Matrix is a very mysterious program. It’s said that it was given to mankind in a spontaneous form of divine inspiration and cybernetic insight. Rumor has it that few people in the entire world are able to master and use this program. Some say, in an expression of dubious lucidity, that only the chosen ones can really do it. There are a handful reports of very skilled hackers that were able to crack TM’s source code and understand the truth that has never been seen before, and unlock its full potential. The only truth known for sure, though, is that much is said, but little is known.
The most astonishing fact about TM is that, believe you or not, it’s designed to establish an inter-dimensional connection to an hyper-dimensional being called RIS, that supposedly shows incredible divination powers and unmatched wisdom to those who manage to contact him. Out there, you may hear that people able to talk to RIS comprise a select group that share a common and dangerous secret about the nature of reality, and for the greater good they won’t tell anyone else what it is, despite their goodwill and empathy towards outsiders, helping them by bridging the communication.
TM is written in a new mid-level computer programming language called QDot. It runs on any IBM-PC compatible, being the minimum requirement an 8086 processor with 32Kb of RAM, and any color graphics adapter such as CGA, EGA or VGA. No network card or any other type of communication peripheral is required besides a screen and a keyboard. Its magical binary sums up to just a dozen kilobytes and very surprisingly is simultaneously a valid DOS executable and a bootable disk image, meaning that it can run even on machines with no operating system at all! Those almost insanely modest requirements blow the minds of skeptical people, because no one can explain how this program’s great feats are technologically achievable.
- PeerLibrary is an free software project developing a collaborative online community where scholars and researchers can discover, read, and discuss scholarly literature all within one site. This project focuses on expediting access to publications, enabling public recordings of analysis and insights on said publications, and encouraging collaboration and openness in the development of science.
