SAGE 4.0.1
Creating a viable free open source alternative to Magma, Maple, Mathematica, and Matlab. more>> Creating a viable free open source alternative to Magma, Maple, Mathematica, and Matlab.
Sage is free open source math software that supports research and teaching in algebra, geometry, number theory, cryptography, and related areas. Both the Sage development model and the technology in Sage itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we are building the car, not reinventing the wheel.
General and Advanced Pure and Applied Mathematics
Use SAGE for studying a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra.
Use an Open Source Alternative
By using SAGE you help to support a viable open source alternative to Magma, Maple, Mathematica, and MATLAB. SAGE includes many high-quality open source math packages.
Use Most Mathematics Software from Within SAGE
SAGE makes it easy for you to use most mathematics software together. SAGE includes interfaces to Magma, Maple, Mathematica, MATLAB, and MuPAD, and the free programs Axiom, GAP, GP/PARI, Macaulay2, Maxima, Octave, and Singular.
Use a Standard Programming Language
You work with SAGE using the highly regarded scripting language Python instead of an obscure language designed for a particular mathematics program. You can write programs that combine serious mathematics with anything else.
Create Notebooks with your Web Browser
Use SAGE from your web browser, which connects either to a program running on your computer, or a program running elsewhere. With the SAGE notebook you can create embedded graphics, beautifully typeset mathematical expressions, add and delete input, and start up and interrupt multiple calculations.
Be Curious
SAGE provides you with easy access to documentation and source code. Type plot? for help on the plot command and plot?? to see the source code. If X is anything, type X.[tab key] to see all commands that apply to X.
Enhancements
Algebra:
- Division over integers (Robert Bradshaw) -- A much simpler and faster algorithm for the divisors function over integers. The new optimized code is faster than a similar integer divisor function in the version of PARI/GP thats bundled with Sage 3.2.1, as well as outperforming a similar integer divisor function found in the version of Magma that Sage 3.2.1 interfaces with.
- Finite field operations (John Palmieri) -- A few methods for finite field elements including additive order, p-th power, and p-th root where p is the characteristic of the field.
Basic arithmetic:
- Polynomials over a field (Burcin Erocal) -- Improving the user interface of polynomial classes.
- Polynomial square roots (John Palmieri, Carl Witty) -- A method to test whether a polynomial is square over the field it is defined. If the polynomial is square, then the method has the option of returning a square root.
Build:
- Improve sage -upgrade (William Stein, Michael Abshoff) -- The Sage upgrade command can now take an optional URL from which it will pull all spkgs, and this URL can be a Sage install. The upgrade command lists packages that will be upgraded before upgrading them, and autodownloads a new version of any spkg that hasnt successfully been installed before upgrading it.
- Problematic CPU flags (William Stein, Michael Abshoff) -- Binary distributions of Sage for Linux (e.g. Ubuntu) may not work properly once installed. The following CPU flags are known to prevent Sage from running properly: sse, 3d, mmx, pni, and cmov.
Calculus:
- Gamma and factorial functions (Mike Hansen, Burcin Erocal, Wilfried Huss) -- Symbolic gamma and factorial functions.
- Update to sympy-0.6.3 (Ondrej Certik) -- Update to the latest upstream of SymPy (sympy-0.6.3), which is a Python library for symbolic mathematics. For more information about SymPy, please visit http://code.google.com/p/sympy/.
- Numerical trigonometry (Robert Bradshaw) -- Optimized floating point evaluation of trigonometric functions such as sine and cosine. For example, numerical calculation of sine via _fast_float_ is now twice as fast as math.sin.
- Floating point calculation (Robert Bradshaw) -- Changing the parsing code for numerical computation to use RDF, which is a better reflection of the underlying precision. For calculus expressions involving real numbers, redundant trailing zeros are removed.
Coercion:
- Coercion API (Robert Bradshaw) -- Some simplification of the coercion interface.
Combinatorics:
- Coding theory (David Joyner) -- Several changes in linear_codes.py which should speed up (and in some cases do:-) some coding theory computations considerably. It adds interfaces to Cython and C functions of Robert Miller, CJ Tjhal, and Jeffery Leon. Speed up of minimum_distance (for codes over GF(2) and GF(3)), the spectrum (=weight_distribution), and permutation_automorphism_group are expected and in most cases achieved. (Also a new function is_permutation_equivalent was added, which interfaces with Robert Millers double coset partition refinement code.)
- Incidence structures and block designs (David Joyner) -- Beginning of an incidence structure class and an implementation of some basic block design algorithms. A few functions require GAPs Design package (which is included in gap_packages-4.4.10_6.spkg) but calling GAP or GAPs Design was only done when the corresponding Sage functionality was missing. Robert Millers recent code on computing the automorphism group of a non-linear binary code was used to implement the automorphism group of a block design.
Testing:
- Added only_optional doctest option (William Stein) -- Added a new option sage -t -only_optional=component that allows one to run only the optional doctests that depend on a given component. Thus instead of much of the optional functionality of Sage being broken, it will now be much easier to automatically test it.

TestDisk & PhotoRec (OS X) 6.3
Download a bundle for data and photos recovery from lost partitions and drives on your Mac. more>>
TestDisk & PhotoRec (OS X) 6.3 is developed to be a powerful application which can help you restore and undelete lost files. It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally erasing your Partition Table). PhotoRec is file data recovery software designed to recover lost pictures or lost files from digital camera memory (CompactFlash, Memory Stick, SecureDigital, SmartMedia, Microdrive, MMC, USB Memory Drives), even Hard Disks and CDRom.
PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover from. Recovered files are instead written in the directory from where you are running the PhotoRec program.
Enhancements: Includes unspecified updates.

Apple Boot Camp 1.4b
Boot Camp - install Windows XP on an Intel-based Mac more>>
More and more people are buying and loving Macs. To make this choice simply irresistible, Apple will include technology in the next major release of Mac OS X, Leopard, that lets you install and run the Windows XP operating system on your Mac. Called Boot Camp (for now), you can download a public beta today.
As elegant as it gets
Boot Camp lets you install Windows XP without moving your Mac data, though you will need to bring your own copy to the table, as Apple Computer does not sell or support Microsoft Windows.(1) Boot Camp will burn a CD of all the required drivers for Windows so you dont have to scrounge around the Internet looking for them.
Optional alt. At startup, hold down the option key (alt) to choose between Mac OS X and Windows.
Run XP natively
Once youve completed Boot Camp, simply hold down the option key at startup to choose between Mac OS X and Windows. (Thats the alt key for you longtime Windows users.) After starting up, your Mac runs Windows completely natively. Simply restart to come back to Mac.
The Boot Camp course
Boot Camp Public Beta provides a straightforward means of letting your Mac run Windows. Heres how it works:
First, you need to make sure your Intel-based Mac has the latest version of Mac OS X and the latest firmware update. These provide technologies that make Boot Camp possible. Its also wise to print out the Installation & Setup Guide.
The Boot Camp burns a CD with the drivers Windows needs to recognize Mac-specific hardware. It is very important to do this before starting the Windows installation.
The software also helps you set aside hard drive space for the Windows installation, without moving any of your Mac files around. Just drag the intuitive slider to choose the size thats right for you. Boot Camp also helps you remove the Windows partition, should you so desire.
Next, insert your Windows installation disc, restart and follow the Windows installation process. The only tricky part is selecting the C: drive manually. Be sure to get this right, or you could erase your Mac files accidentally. Remember, Apple Computer does not sell or support Microsoft Windows.
After the installation process is complete and your Mac has booted Windows, youll need the Macintosh Drivers CD you burned previously. When you insert the CD, it will automatically install the drivers. Follow the instructions in the Installation & Setup Guide for helpful hints.
Dont forget to follow best practices for updating and protecting your Windows system (see Word to the wise to right).
See Apples Boot Camp Public Beta page for more information.

Utility that can recover deleted files from an ext3 partition more>> Utility that can recover deleted files from an ext3 partition
extundelete is a utility that can recover deleted files from an ext3 partition. extundelete is based on the ext3grep program.
extundelete uses the information stored in the partitions journal to attempt to recover a file that has been deleted from the partition.
To use extundelete, you must know the name of the file (or the inode number) of the deleted file relative to the root of the partition.
There is no guarantee that the file will be able to be undeleted, so always try to have a good backup system in place, or at least put one in place after recovering your files!
Enhancements
- Reduced initialization time.
- Greatly improved
- restore-alls ability to link an inode with a file name.
- Added restore-directory option to restore files in a specific directory only.
