HuCam 1.0
HuCam - Make a tour in Hungary through your dashboard. more>> Master Positive and Negative Integers with PanIntegers
Addition, Subtraction, Multiplication and Division of Integers, Order of Calculations
Tutorial
Introduces the rules for the multiplication and division of positive and negative integers, followed by the concept of addition and subtraction. Teaches the easy way to remove brackets. With these basic skills, students will be able to do calculations of integers easily.
Simple mental exercises at the end of each session help to strengthen the concepts learnt.
Practice
PanIntegers is capable of generating thousands of sums for drills to ensure that the student masters these very important basic skills which will be needed in future for the learning of algebra. It includes sums on addition and subtraction, multiplication and division, order of calculations, removal of brackets and simple indices such as (-3)2 + 6.
The sums get progressively more difficult if a student is doing well. If a student is doing badly, the numbers will be kept simple to let him focus on the concepts.
Worked Examples
Almost 60 worked examples provide help for students who have difficulty in doing the sums.
Reports
You can print out a report at the end of each practice session. The report shows each sum with its correct answer and the students answer marked. It also includes the percentage score, the average time taken to do each sum and other details.
Special Features
Unlike some other programs, PanIntegers is able to accept alternative correct answers, for example, +2 instead of 2.
This feature is important because at this early stage, students may want to put in the "+" sign for emphasis.
It allows two players to compete with each other on one computer, reducing the number of computers required for a class by half. Each player can do the sums at his own pace.
It prints two separate detailed reports, each showing the sums done by the individual player.
Provides an excellent foundation for the learning of basic algebra.<<less

Keiths Image Stacker 4.2
Keiths Image Stacker - Image processing program more>>
What Keiths Image Stacker provides, more than anything else, is a workspace in which to align many similar images (say from a quicktime movie of Jupiter taken through a telescope with a webcam) and then to produce a stack of the images, which consists of a single image that comprises either the sum, or the average, or some value in between of the individually stacked images.
Stacking images is a well-established method for increasing the signal-to-noise ratio in a series of similar images. True "information" will shine through the stack, while random noise will drop out.
Enhancements:
- In the Unsharp Mask and Laplacian Sharpening Interfaces, if you attempted to redefine a the preview bounds but released the mouse button without dragging a rectangle, this could cause subsequent crashes later on. Should be fixed.
- v4.1 introduced a bug into the Open FITS file interface, in which each channel opened would erase any existing channels in the stack. This made it impossible to recover an RGB stack from three FITS files. The problem has been solved.
- The sliders in the Power Spectrum Sorting Interface were being memory leaked. Fixed.
- Fixed a bug that could cause a crash when the Clips Window is closed.
- Centroid alignment wasnt using the proper algorithm to determine a pixels overall value (using average instead of max of RGB components). Fixed.
- Preview bounds for a variety of operations were not properly displayed in the FrameStack window if the FrameStack window size did not perfectly match that actual FrameStacks size. Should be fixed.
- The Laplacian Sharpening Interface did not respect the pin-zero and pin-one boxes when creating the final result after hitting the OK button. This would cause the final result to suddenly change so as to not match the preview that was available immediately before hitting OK. This is fixed now.
- The Laplacian Sharpening Interface did not remember the value of the DC term properly after being closed. Fixed.
- Half bug, half missing feature in some cases, the Marking Clip Rect (cyan border around a clip) often was not drawn for many operations. Several occurances of this bug were fixed in v4.1. Several more are fixed here.
- Turns out I was calculating 2D power spectrums quite incorrectly. Sorting by power spectrum will hopefully improve now.
- A smattering of small changes and fixes to the precise dimensions of power-2 operations bounds rects and methods for getting pixels from GWorlds (inclusion of the right and bottom edges of pixels of a bounds rect primarily)
- In the Unsharp Masking Interface, if you moved the preview rect, the old preview rect was not restored to the original image. Fixed.
- If the RGB channels of the Frame Stack were independently aligned, the single channel views in the Histograms/Levels Interface were not drawn properly. Fixed (and eliminated now that those checkboxes are gone)
- If the FrameStack was rebuilt, the RGB alignments on the FrameStack were not reinitialized to (0, 0). Bug? Stupid feature? Either way, they are initialized now.
Changes:
- Added Debayering on the individual clips, for use with cameras that have been "RAW" modded to receive the Bayer pattern directly from the cameras CCD.
- Decreased the Event reaction time slightly. This vastly cuts the amount of CPU resources being hogged by the program without noticably affecting the programs performance.
- When sorting frames by power spectrum distribution, there is now a high frequency cutoff slider in addition to the old low frequency cutoff slider. The score of a frame will be the ratio of the sum of power between the cutoffs to the sum of total power. Initial experiments suggest that this can definitely improve the final sorted order of the frames.
- A few sorting methods have been completely removed because people continue to be confused as to how to properly sort the frames in such a way as to get satisfying results. At the same time, the sorting menu has been garnished with some textual notes that should prod people in the right direction under most circumstances.
- Significant changes to centroid alignment. Centroid alignment is considerably faster than difference alignment, especially when the misalignments are large. However, it may not produce the optimal alignment (I am unsure about this. Perhaps it is optimal after all, in which it is definitely superior to the difference method). Therefore, it is suggested to use centroid alignment (4-key) first and then clean up with a difference alignment using the 3-key. The 1-key and 2-key difference alignments, despite fixing large misalignments better than the 3-key method, are slower than the centroid method, which is why centroid followed by 3-key is recommended as the best overall approach.
- Added Cross-Correlation alignment. It is used in the same fashion as the existing four methods of alignment, three for difference and one for centroid. Simply hold down the 5 key and click on a clip or a selection of clips to use it. You must, however, use a power-of-two Operations Bound rect. Otherwise the program simply beeps. While this method usually works pretty well, it sometimes gets confused and produces a completely ridiculous alignment. Additionally, it is noticeably slower than the other alignment methods. Frankly, I think the centroid method is best for macro-alignments and the key-3 difference method is best for micro-alignments.
- Added a new operation on the FrameStack called Fourier Transform Editor. This allows you to literally paint out those parts of the Fourier transform of the stack that correspond to periodic interference patterns, such as the "herring bone" pattern that pervades many long exposure modified webcams. Aligning with a brightness threshold (which deals with the same problem in some cases) is still crucial, since it provides an optimal and sharp alignment, but if the final stack is not deep enough, it can still exhibit these kinds of interference patterns. This tool will virtually eliminate them. I would guess that it should also help in mitigating Bayer pattern effects, although I have not experimented with this yet.
- The centroid alignment wasnt using the brightness threshold before. Only the difference alignment was. Now centroid alignment uses it too, as does the new cross correlation alignment (although it may introduce unnatural edges into the image which could mess up the cross correlation alignment).
- Added a new checkbox to the Open Movie Interface that lets you specify that frames should be aligned on the fly as they are brought into the workspace. Not only does this allow you to align at the time of opening the file (which doesnt really save any time if you think about it), but it allows you to specify a bounds rect in the Open Movie Interface that only needs to fit around the object in the first frame, not the full drifted area of the object in all frames. This will save memory of course. Likewise this prevents the object from drifting outside the specified rect and being clipped by accident if you didnt make the original rect big enough in the first frame.
- Added four menu commands to the View menu for viewing the RGB channels of the FrameStack individually. Note that the 1, 2, and 3 command key menu equivalents have been reassigned in accordance with this change. These menu commands work even when the various operations dialogs are open. Note, however, that the channel appearances interact with the preview rects in some strange ways. I am still working on designing the best possible interface and interaction for all the possible combinations of settings.
- Removed the recently added channel checkboxes in the Histogram/Levels Interface. They are no longer necessary now that the much easier to use menu command replacements are available.
- Documentation updates.
- Resampling of the clips used to occur on the original opened-from-disk form of the clip. It now occurs on the modified form and makes the modified form the original form after resampling is completed. This means any operations become permanant and should be turned off prior to resampling if you dont want this, including dark frame subtraction, flat field division, normalization, median filtering, and alignment. In particular, this applies to deBayering as well, but deBayering must be done before resampling, as it will not work properly after resampling.
- Increased the maximum slider value for the Mask Intensity sliders in the Unsharp Masking and Laplacian Sharpening Interfaces.

Loans are the conventional installment loans with an initial fixed loan amount to be paid back in regular payments over a fixed period of years at a specific interest rate.
Investments are an initial lump sum amount of money that grows to a larger amount over a period of years at a fixed rate of growth, as would be for the case of investing a lump sum from an inheritance or winning the lottery.
Deposits are regular periodic deposits of a fixed amount into an account that grows at a constant rate over a fixed number of years, such as an investment club or a regular savings plan.
Withdrawals determine how long you can take a periodic fixed amount from an initial lump sum investment at a fixed growth (interest) rate before the account is totally depleted, answering the question How long will my life-long savings last after I retire?
Number Chase Card Maker 1.0
Prints a series of linked cards for a simple arithmetic game more>> Prints a series of linked cards for a simple arithmetic game
Number Chase Card Maker makes cards for a simple mental arithmetic game.
Number Chase Card Maker prints a series of linked cards or slip of paper, each with an answer to another card and a question.
You need to print a set with on card for each child in the class. You need to use all the cards, so if a child is off, you can give two slips to another child. Once the cards are given out, a child reads out her question, the child with the answer to that question, calls it out, followed by his question and so on. The last question will lead back to the first child.
The popup button at the bottom right lets you choose a small image that will be printed on each card, this helps keeps ets of cards together and not get mixed up.
The project will warn you if you have not chosen a combination of sums with enough unique answers, e.g. there are very few different answers to division sums, you will not be able to make a division only chase unless you have a very small class.
System requirements:
- G3 Processor
- SuperCard Player
- 128 RAM

CUDA 2.2
A C language development environment for CUDA-enabled GPUs. more>> A C language development environment for CUDA-enabled GPUs.
The CUDA Toolkit is a C language development environment for CUDA-enabled GPUs.
In a matter of a few years, the programmable graphics processor unit has
developed into an absolute computing workhorse. With multiple cores driven by very high memory bandwidth, todays GPUs offer incredible resources for both graphics and non-graphics processing.
The main reason behind such an evolution is that the GPU is specialized for compute-intensive, highly parallel computation exactly what graphics rendering is about and therefore is designed such that more transistors are devoted to data processing rather than data caching and flow control.
The CUDA development environment includes:
- nvcc C compiler
- CUDA FFT and BLAS libraries for the GPU
- Profiler
- gdb debugger for the GPU (alpha available in March, 2008)
- CUDA runtime driver (now also available in the standard NVIDIA GPU driver)
- CUDA programming manual
The CUDA Developer SDK provides examples with source code to help you get started with CUDA. Examples include:
- Parallel bitonic sort
- Matrix multiplication
- Matrix transpose
- Performance profiling using timers
- Parallel prefix sum (scan) of large arrays
- Image convolution
- 1D DWT using Haar wavelet
- OpenGL and Direct3D graphics interoperation examples
- CUDA BLAS and FFT library usage examples
- CPU-GPU C- and C++-code integration
- Binomial Option Pricing
- Black-Scholes Option Pricing
- Monte-Carlo Option Pricing
- Parallel Mersenne Twister (random number generation)
- Parallel Histogram
- Image Denoising
- Sobel Edge Detection Filter
- MathWorks MATLAB Plug-in
Main features:
- Standard C programming language enabled on a GPU.
- Unified hardware and software solution for parallel computing on CUDA-enabled NVIDIA GPUs.
- CUDA compatible GPUs range from lower power notebook GPUs to high performance, multi-GPU systems.
- CUDA-enabled GPUs support the Parallel Data Cache and Thread Execution Manager.
- Standard numerical libraries for FFT (Fast Fourier Transform) and BLAS (Basic Linear Algebra Subroutines).
- Dedicated CUDA driver for computing.
- Optimized direct upload and download path from the CPU to CUDA-enabled GPU.
- CUDA driver interoperates with OpenGL and DirectX graphics drivers.
- Support for Linux 32/64-bit and Windows XP 32/64-bit operating systems.
- Direct driver and assembly level access through CUDA for research and language development.
Enhancements
- Visual Profiler for the GPU - The most common step in tuning application performance is profiling the application and then modifying the code. The CUDA Visual Profiler is a graphical tool that enables the profiling of C applications running on the GPU. This latest release of the CUDA Visual Profiler includes metrics for memory transactions, giving developers visibility into one of the most important areas they can tune to get better performance.
- Improved OpenGL Interop - Delivers improved performance for Medical Imaging and other OpenGL applications running on Quadro GPUs when computing with CUDA and rendering OpenGL graphics functions are performed on different GPUs.
- Texture from Pitch Linear Memory - Delivers up to 2x bandwidth savings for video processing applications.
- Zero-copy - Enables streaming media, video transcoding, image processing and signal processing applications to realize significant performance improvements by allowing CUDA functions to read and write directly from pinned system memory. This reduces the frequency and amount of data copied back and forth between GPU and CPU memory. Supported on MCP7x and GT200 and later GPUs.
- Pinned Shared Sysmem - Enables applications that use multiple GPUs to achieve better performance and use less total system memory by allowing multiple GPUs to access the same data in system memory. Typical multi-GPU systems include Tesla servers, Tesla Personal Supercomputers, workstations using QuadroPlex deskside units and consumer systems with multiple GPUs.
- Asynchronous memcopy on Vista - Allows applications to realize significant performance improvements by copying memory asynchronously. This feature was already available on other supported platforms but is now available on Vista.
- Hardware Debugger for the GPU - Developers can now use a hardware level debugger on CUDA-enabled GPUs that offers the simplicity of the popular open-source GDB debugger yet enables a developer to easily debug a program that is running 1000s of threads on the GPU. This CUDA GDB debugger for Linux has all the features required to debug directly on the GPU, including the ability to set breakpoints, watch variables, inspect state, etc.
- Exclusive Device Mode - This system configuration option allows an application to get exclusive use of a GPU, guaranteeing that 100% of the processing power and memory of the GPU will be dedicated to that application. Multiple applications can still be run concurrently on the system, but only one application can make use of each GPU at a time. This configuration is particularly useful on Tesla cluster systems where large applications may require dedicated use of one or more GPUs on each node of a Linux cluster.
Pinned Memory Support:
- These new memory management functions (cuMemHostAlloc() and cudaHostAlloc()) enable pinned memory to be made "portable" (available to all CUDA contexts), "mapped" (mapped into the CUDA address space), and/or "write combined" (not cached and faster for the GPU to access).
- cuMemHostAlloc
- cuMemHostGetDevicePointer
- cudaHostAlloc
- cudaHostGetDevicePointer
Function attribute query:
- This function allows applications to query various function properties.
- cuFuncGetAttribute
2D Texture reads from pitch linear memory:
- You can bind linear memory that you get from cuMemAlloc() or cudaMalloc() directly to a 2D texture. In previous releases, you were only able to bind cuArrayCreate() or cudaMallocArray() arrays to 2D textures.
- cuTexRefSetAddress2D
- cudaBindTexture2D
Flags for event creation:
- Applications can now create events that use blocking synchronization.
- cudaEventCreateWithFlags
New device management and context creation flags:
- The function cudaSetDeviceFlags() allows the application to specify attributes such as mapping host memory and support for blocking synchronization.
- cudaSetDeviceFlags
Improved runtime device management:
- The runtime now defaults to attempting context creation on other devices in the system before returning any failure messages. The new call cudaSetValidDevices() allows the application to specify a list of acceptable devices for use.
- cudaSetValidDevices
Driver/runtime version query functions:
- Applications can now directly query version information about the underlying driver/runtime.
- cuDriverGetVersion
- cudaDriverGetVersion
- cudaRuntimeGetVersion
New device attribute queries:
- CU_DEVICE_ATTRIBUTE_INTEGRATED
- CU_DEVICE_ATTRIBUTE_CAN_MAP_HOST_MEMORY
- CU_DEVICE_ATTRIBUTE_COMPUTE_MODE
Documentation:
- Doxygen-generated and cross-referenced html, pdf, and man pages.
- Runtime API

iShred 1.1
iShred provides an interface to the SRM or secure delete function more>>
iShred is a front end to the Unix "srm" command. As far as what it does, the man page for "srm" sums it up best...
srm removes each specified file by overwriting, renaming, and truncating it before unlinking. This prevents other people from undeleting or recovering any information about the file from the command line.
USE AT YOUR OWN RISK. FILES DELETED WITH THIS PROGRAM ARE NOT RECOVERABLE, MAKE SURE YOU KNOW WHAT YOU ARE DOING.
Enhancements:
- added option to skip warning panel on launch
- added option to use the 35 pass Gutmann method
