POI provides a java ports of popular OLE 2 file formats.
The POI project contains several components for dealing with popular OLE 2 formats in Java. POIFS is a pure Java implementation of the OLE 2 Compound document format.
HSSF is a pure Java implementation of Excel 97 XLS file format based on POIFS. HSSF Serializer is a pure Java serializer for Cocoon 2 that uses the Gnumeric XML format to output XLS.
Full documentation of the POIFS file format is included. If you wish to output reports in the Excel file format, or if you have existing XML documents that you need to get into Excel, then this project is probably what youre looking for.
Enhancements:
- Support for evaluating formulas in HSSF, initial support for HSLF (PowerPoint), and support for editing document properties (HPSF).

ppsei short from PPS Extract Images is a simple command line program, which tries to extract images from Microsoft PowerPoint documents (PPS/PPT).

Because i get a lot of mails with attached PPS/PPT in, containing some nice images (about universe, about pretty girls, etc). The sender people are using this file format as an image-container, or image-encapsulator.

They could use tar/zip/..., but somehow PPS is the general. On *nix systems only resource-consume application can handle this file formats (openoffice, wine + win.exe), so i decided to write this tool.

Currently only JPEG and PNG files can be extracted. Because the PPS file format is not so well-documented as the gnumeric :-), there is no guarantee, that all images will be grabbed correctly. But the experience is, that it works!

As i said, this is a command line program: you can call it from SHELL (or from favorite email software). It takes only the PPS file(s) as argument, and will extract all detected images to the current directory:

$ ppsei universe.pps beauty-islands.ppt
...
$ gqview (start here some image viewer application, to see the result)

PhotoRec is a small tool to recover pictures from digital camera memory. Photorec software searches for MOV and JPEG headers, and because there is (usually) no data fragmentation, it can recover the whole file.
It can recover data from CompactFlash, Memory Stick, SecureDigital, SmartMedia, Microdrive, MMC, USB Memory Drives...
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.
Photorec ignores the filesystem, this way it works even if the filesystem is severely damaged.
It can recover lost files at least from:
- FAT,
- NTFS,
- EXT2/EXT3 filesystem
Digital Camera
PhotoRec has been successfully tested with:
- Canon EOS300D, 10D
- HP PhotoSmart 620, 850, 935
- Nikon CoolPix 775, 5700
- Olympus C350N, C860L, Mju 400 Digital, Stylus 300
- Sony DSC-P9
- Praktica DCZ-3.4
- Casio Exilim EX-Z 750
PhotoRec searchs known file header and because there is no data fragmentation (usually), it can recover the whole file. Photorec recognises numerous file format including:

Enhancements:
- A new method for handling fragmented data is now used, making recovery more reliable and faster.
- This release can be set to search for files in FAT16/FAT32 unallocated space only, which avoids wasting time recovering files that are still accessible, making the recovery of lost files much faster and more efficient.
- New file formats have been added.

PloneExFile provides a Plone/AT content type with an attachment, supporting preview & indexing & lock.
PloneExFile is a file like content type that provides indexing and preview support for MS Word, MS Excel, MS Powerpoint, PDF and OO Writer files.

- Plone 2.5
- Plone 2.1
Enhancements:
- Added German translations and fixed description of upgrade procedure; provided by Carsten Kirck. Thank you!

BasicLinux is designed specifically for old PCs. It uses a small kernel and busybox to provide a low-RAM Linux, capable of browsing the web, doing email, and functioning as an X terminal.

The current release of BasicLinux is particularly suitable for old laptops -- it has PCMCIA capability and includes MagicPoint (a presentation tool similar to PowerPoint).

The current release of BasicLinux is 3.32. BasicLinux comes in two versions: one boots from a DOS harddrive, the other boots from floppies. Both versions have the option to install themselves to a Linux partition on the harddrive.

BasicLinux has a slim IDE kernel and a small set of common modules. If you need a more capable kernel and/or additional kernel modules, you should get them from Slackware 7.1. You will find kernels in the /kernels directory and modules in the /modules directory.

ImageServer is a software for maintaining archives of images. Theres much software available to manually view, categorize and search images. ImageServer was designed to solve a different problem:
Imagine being a photographer or photo agency: You have a lot of images in many formats, all stored in a directory structure - your archive.
This creates at least two problems:
- The archive may contain different images with the same name. What do you do when a customer orders "flowers.tif" and this name exists in twenty different subfolders in your archive?
- The customer doesnt need your original 22megapixel 16-bit tiff file for his powerpoint presentation or layouting, he wants a small jpeg instead.
The first problem can be managed by assigning unique names to images every time an image is put into the archive.
The second problem is a little more difficult. Youll have to convert the requested images to smaller JPEGs. After doing that for too many times, you start caching the small JPEGs so you wont have to convert again for the next customer asking for that image. But then, you edit the original image and forget to update the JPEGs. Furthermore, its not enough to keep these resized jpegs for presentations, your customers graphics department also wants correctly downsampled eps images for layouting advertisements in QuarkXPress. So you start having two slaveArchives - one with JPEG and one with EPS images - and spend half of your day trying to synchronize the three.
ImageServer solves both problems automatically. It is a program with a nice GUI, configured to watch your masterArchive. As soon as images are put into any subfolder, theyll be assigned unique names if necessary. Afterwards, each image is read, and for each defined slaveArchive, a preview is created and saved. The same happens when an image in the masterArchive is altered. All this works completely automatically, theres nothing youll have to do; the GUI is just for being able to watch whats happening.
Main features:
- Input file checking: as soon as an image is put into the archive, ImageServer checks the extension to see whether it really is an image. If not, it is put into a specified folder outside of the archive.
- If configured to do so, an image without a suiting name is assigned a new name which is constructed of both the subfolders it resides in and a unique-per-subfolder serial number of arbitrary length.
- When detecting a change in the masterArchive, ImageServer can play a sound.
- When starting to convert an image, ImageServer can play a sound.
- ImageServer can remember the names it has already assigned to images in the past. This way, names assigned to an image A will never be assigned to another image B after A has been deleted.
- Any number of slaveArchives can be defined, and they can be in any location.
- Each defined slaveArchive can have completely different settings for the images that will populate it. Resizing or resampling? RGB or CMYK? Jpeg, EPS, PNG or TIFF?
- You can choose whether each slaveArchive should inherit the exact same directory structure from the masterArchive or whether the slaveArchives images should all be put into the same folder.
- In case dazuko missed something, you can tell imageserver to manually look into a folder. It can then either process all images in that folder or only those where slaveArchive-images are missing.
