Dbmail is the name of a group of programs that enable the possibility of
storing and retrieving mail messages from a database (currently MySQL,
PostgreSQL or SQLite).
* Scalability.
Dbmail is as scalable as the database system that is used for the mail
storage. In theory millions of accounts can be managed using dbmail. One
could, for example, run 4 different servers with the pop3 daemon each
connecting to the same database (cluster) server.
* Manageability.
Dbmail is based upon a database. Dbmail can be managed by changing settings
in the database (f.e. using PHP/Perl/SQL), without needing shell access.
* Speed.
Dbmail uses very efficient, database specific queries for retrieving mail
information. This is much faster then parsing a filesystem.
* Security.
Dbmail has got nothing to do with the filesystem or interaction with other
programs in the Unix environment which need special permissions. Dbmail is
as secure as the database it's based upon.
* Flexibility.
Changes on a Dbmail system (adding of users, changing passwords etc.) are
effective immediately.

ndiff is a utility for comparing putatively similar files, ignoring small
numeric differences. The utility is written by Nelson H. F. Beebe and
covered by the GNU General Public License (GPL), version 2. It may be
built with arbitrary precision support (more powerful) or using built-in
floating point precision, see Makefile.
Assessing the consistency of a numerical program run in multiple
environments (operating systems, architectures, or compilers) can be a
difficult task for a human, as small differences in numerical output values
are expected. File differencing utilites, such as diff(1), will generally
produce voluminous output, often longer than the original files.
ndiff solves this problem. Taking two text files expected to be
identical, or at least numerically similar, it allows to specify absolute
and/or relative error tolerances for differences between numerical values
in the two files, and then reports only the lines with values exceeding
those tolerances. It also tells by how much they differ. A simple example:
% ndiff --relative-error 1.0e-3 test019.txt.1 test019.txt.2
### Maximum relative error in matching lines = 8.64e-51 at line 129 field 4
From <http://cran.R-project.org/doc/FAQ/R-FAQ.html#What-is-R_003f>:
R is a system for statistical computation and graphics. It consists of
a language plus a run-time environment with graphics, a debugger,
access to certain system functions, and the ability to run programs
stored in script files.
The core of R is an interpreted computer language which allows branching
and looping as well as modular programming using functions. Most of the
user-visible functions in R are written in R. It is possible for the user
to interface to procedures written in the C, C++, or FORTRAN languages
for efficiency. The R distribution contains functionality for a large
number of statistical procedures. Among these are: linear and generalized
linear models, nonlinear regression models, time series analysis, classical
parametric and nonparametric tests, clustering and smoothing. There is also
a large set of functions which provide a flexible graphical environment for
creating various kinds of data presentations. Additional modules ("add-on
packages") are available for a variety of specific purposes.
The purpose of this project is to develop a free (open source),
platform independent alternative to Origin. QtiPlot is being actively
improved, all your suggestions to our "wish to" list and all your
contributions are most welcome!
Features:
* QtiPlot is fully scriptable via Python, which gives you the
possibility to use powerfull existing scientific tools, such as
SciPy
* OpenGL based 3D Plotting
* Publication quality 2D plots
* Easy export of plots to vector formats (EPS, PS, PDF) and
to other various image formats (BMP, JPG, PNG, TIFF etc ...)
* Powerful and versatile spreadsheets and calculations in column-logic
* Easy ASCII-Import/Export of single or multiple files
* Linear and non-linear y=f(x) curve fitting and estimation of
statistical errors of the fit-parameters
* Multi-peak fitting with Gaussian and Lorentzian peak profiles
* Data analysis: statistics, sorting, FFT, data smoothing
(Savitzky-Golay, FFT smoothing, and moving window average), data
filtering (low/high/band pass and band block filters),
convolution/deconvolution, correlation, interpolation, numerical
integration/differentiation, etc...
* Matrices optimized for 3D plotting
* Templates support: all the settings for plots (2D/3D), tables
and matrixes can be saved to ASCII files and restored later on for
a fast editing process
* Project files based on folders, a powerful project explorer with
extensive built-in features: drag and drop, searching facilities,
etc...
U-Boot loader for Wandboard Solo, Dual, and Quad.
Install the u-boot.imx file onto the boot disk using:
dd if=u-boot.imx of=/dev/whatever bs=1k oseek=1 conv=sync
The U-Boot built by this port expects the first 1MB of the boot media to
be reserved for the U-Boot executable and saved environment. The u-boot.imx
file begins at an offset of 1K from the start of the boot disk. The U-Boot
environment area begins at an offset of 512K.
This version is patched so that:
* ELF and API features are enabled to support ubldr.
* A single U-Boot image supports Solo, Dual[lite], and Quad processors.
* When the selected board has multiple SD or MMC devices available, the
mmc0 device in U-Boot (and thus the disk0 device in loader(8)) will be
whichever device U-Boot was loaded from by the ROM bootloader routines.
The sources for this port were originally obtained from commit 87f595d1ee
at https://github.com/TechNexion/U-Boot-edm/ which appears to be a slightly
modified fork of the stock U-Boot 2013.10 release. As of this writing,
the changes in this fork have not been rolled back into upstream U-Boot.
For general information about U-Boot see WWW: http://www.denx.de/wiki/U-Boot
Junicode is an advanced Unicode font for medieval scholars, including the
full range of characters for languages written in the Latin script. It
also mostly implements the recommendation of the Medieval Unicode Font
Initiative (MUFI).
The following languages are fully supported: Old and Middle English, Old
Icelandic, Runic, Latin, Gothic and Sanskrit transliterations, IPA
(International Phonetic Alphabet) and Greek (based on the Greek Double
Pica cut by Alexander Wilson of Glasgow in the eighteenth century).
Junicode supports the following OpenType features: f and long-s ligatures,
contextual and stylistic alternates (calt, salt), horizontal kerning
(kern), discretionary ligatures (circled numbers and letters via dlig),
MUFI historical ligatures (hlig), glyph (de)composition (ccmp), correct
positioning of combining marks -- mark-to-base (mark) and mark-to-mark
(mkmk), small caps (smcp and c2sc), old-style figures (onum), super- and
subscript numbers (sups and subs), Unicode fractions (frac), swashes
(swsh) and mirrored runes (rtlm).
Junicode's OpenType style sets provide support for Nordic and Insular
letter-forms, Old English typography, enlarged minuscules, E caudata,
alternate yogh, MUFI's overlined/deleted characters and many more.
This utility can be used to test performance of storage devices.
First, one need to generate file with I/O operations:
# set mediasize=`diskinfo /dev/<device> | awk '{print $3}'`
# set sectorsize=`diskinfo /dev/<device> | awk '{print $2}'`
# raidtest genfile -s $mediasize -S $sectorsize -n 50000
It will generate test which contains 50000 I/O requests with random
size and random offset. Size is a multiple of sectorsize, but less than or
equal to 128kB (maxium size of I/O request). I/O request type (READ or WRITE)
is random as well.
All test data are stored in 'raidtest.data' file in current working directory.
To run test, one should type:
# raidtest test -d /dev/<device> -n 10
This command will read test data from 'raidtest.data' file, run 10 processes
which will be used to send requests to the given device in parallel.
When test is finished you will see statistics:
Bytes per second: <x>
Requests per second: <y>
If you compare performance of two storage devices, use the same data file!
usage: raidtest genfile [-frw] <-s mediasize> [-S sectorsize] <-n nrequests> [file]
raidtest test [-Rrw] <-d device> [-n processes] [file]
where:
-d device path to tested device
-f if raidtest.data file or specified file already exists,
remove it and create new one
-n nrequests number of requests to generate
-n processes number of processes to run
-r generate/run only READ requests
-R generate random data for write requests
-s size of destination device
-S sector size of destination device
-w generate/run only WRITE requests
file path to the data file instead of default 'raidtest.data'
