Jspice3 is a circuit simulator developed to meet the needs of researchers
working with superconducting Josephson junction circuits, yet the program
has the flexibility and power to meet the needs of other technologies.
Jspice3 is an adaptation of the Berkeley Spice3f4 program, with added
features. One added feature is a built-in graphical input front end for
schematic capture. While displayed, simulations can be run and data
plotted through this graphical interface.
While not as powerful or as pretty as the Xic graphical interface, it
holds its own in functionality.
A significantly enhanced output plotting capability is provided, and
Jspice3 has enhanced script interpretation capability.

It is a free library for decoding ATSC A/52 streams, aka AC-3. The
A/52 standard is used in a variety of applications, e.g., digital
television and DVD. The main goals in liba52 development are:
Portability - most of the code is written in C, and when we use
platform-specific optimizations we always have a generic C routine
to fall back on.
Reusability - we do not want liba52 to include any project-specific
code, but it should still include enough features to be used by
very diverse projects.
Precision - We are trying to implement all of the A/52 standard,
and to have a very precise output by doing all the calculations in
floating point. We have a test suite that detects any deviation in
the output when compared to previous versions. We do not have access
to official A/52 test vectors though, so we have to use our judgement
to ensure that such deviations are only introduced when we fix bugs!
Speed - liba52 is really fast, on any modern PC it should take only
a few percent of CPU time.

Dolly is used to clone the installation of one machine to (possibly
many) other machines. It can distribute image-files (even gnu-zipped),
partitions or whole hard disk drives to other partitions or hard
disk drives. As it forms a "virtual TCP ring" to distribute data,
it works best with fast switched networks (we were able to clone a
2 GB Windows NT partition to 15 machines in our cluster over Gigabit
Ethernet in less than 4 minutes).
As dolly clones whole partitions block-wise it works for most
filesystems. We used it to clone partitions of the following type:
Linux, Windows NT, Oberon, Solaris (most of our machines have multi
boot setups). We have a small (additional) Linux installation on
all of our machines or use a small one-floppy-disk-linux (e.g.
muLinux) to do the cloning. On newer machines we use PXE to boot a
small system in a RAM disk. From that system we then clone the hard
disks in the machines.
Provides an object-oriented interface to either the POSIX mmap() or
Win32 equivalent APIs to memory map a file into a process's address
space for general memory access. IPC::Mmap provides only a minimal
interface without the additional overhead of tie'd variables or
locking enforced in other modules (e.g., Sys::Mmap, Win32::MMF); hence,
the application is responsible for performing read()'s and write()'s
on the IPC::Mmap object, and calling any needed lock() and unlock()
methods, as required by concurrent processes.
Memory mapped files provide an alternate shared memory mechanism for
multiple processes. The technique maps the OS's file system buffers
for a given file into each mmap()'ing process's virtual memory space,
thereby permitting each process to essentially share the same physical
memory. Refer to the excellent "Advanced Programming in the UNIX
Environment", Stevens et al., Addison-Wesley Publisher for a detailed
reference on the POSIX implementation. IPC::Mmap provides OS-agnostic
wrappers for both the POSIX and Win32 memory mapped file capabilities.
The Vowpal Wabbit (VW) project is a fast out-of-core learning system
sponsored by Microsoft Research and (previously) Yahoo! Research.
There are two ways to have a fast learning algorithm: (a) start with a slow
algorithm and speed it up, or (b) build an intrinsically fast learning
algorithm. This project is about approach (b), and it's reached a state
where it may be useful to others as a platform for research and experimentation.
There are several optimization algorithms available with the baseline
being sparse gradient descent (GD) on a loss function (several are available).
这个模块试图以有效的,灵活的方式,而不需要借助于外部工具和模块来解决发生在繁体
中文和简体中文转换中的常见问题,。
安装完成该模块后,你将有两个额外的编码格式:big5-simp 是 Big5 到 Unicode
的简体中文映射(反之亦然),gbk-trad 是 CP936 (一般成为 GBK)到 Unicode
的繁体中文映射。
该模块默认情况下通过多种 xxx_to_yyy 函数输出变量,xxx 和 yyy 是 big5、
gb(例如 GBK/CP936)、simp(简体中文 unicode)、或者 trad (繁体中文
unicode)中的一个。
This plugin displays the current keyboard layout, and refreshes when
layout changes. Also the layout can be switched by simply clicking on
the plugin. The new version can display the layout as text label and
also as an image of the corresponding country's flag. If the flag
image is unavailable then the plugin falls back to displaying text
label for that layout.
This plugin is used along with the XKB extension. For now the keyboard
layouts cannot be configured from the plugin itself, they should be
set in the Xorg file or some other way (e.g. setxkbmap).
bbfreeze creates standalone executables from Python scripts. It's similar
in purpose to the well known py2exe for Windows, py2app for OS X, PyInstaller
and cx_Freeze (in fact ancient versions were based on cx_Freeze.
And it uses the modulegraph package, which is also used by py2app).
It has the following features:
- ZIP/Egg file import tracking
- Binary dependency tracking (e.g. shared libraries)
- Multiple script freezing support
- Python interpreter included (named 'py')
- Automatic pathname rewriting (pathnames in tracebacks are relative)
- New distutils command: bdist_bbfreeze
This way of associating structs with Perl space objects is designed to supercede
Perl's builtin T_PTROBJ with something that is designed to be:
Extensible
- The association of the pointer using sv_magicext can be done on any data type,
so you can associate C structs with any representation type.
- This means that you can add pointers to any object (hand coded, Moose or
otherwise), while still having instance data in regular hashes.
Opaque
- The C pointer is neither visible nor modifiable from Perl space.
- This prevents accidental corruption which could lead to segfaults using
T_PTROBJ (e.g. $$ptr_obj = 0).
