Dysprosium: Messiah's "Codes For Us" PDF Software Package Under Way

(For the latest PDF files Merger Software please have a look at the top of the left margin, inside the red box.) Now I have fulfilled part of my promises for a free PDF software suite, without overly bloating it. Under different stress tests I have done , there appears a couple of issues. For example, some rare happening exception would not report them in a relevant dialogue. As the software, in contrast to some other software, keeps the original file untouched, these exceptions have not a damaging edge. But, in principle, they should be reported. Other important issue is when PDF files exceed a size of 0.5 GB. One needs to have enough resources in their computer to handle them. All other applications should be closed. I have tested merging of two 450 MB files with 4GB of RAM and effective CPU speed of 4.5 GHz that takes almost (less than) ten minutes. (18/March/11: New findings show it in 3 minutes, gives 1 GB, and even 1.5 GB. 25/October/2011: 3GB using Windows 7 64 bits, 8 GB ddr3. Please have a look at new pictures at the tab page at the top of this blog) Consider that for ordinary documents that size is equivalent of tens of thousands of pages (6 k per page makes 450 MB equal to 75000 pages. 100 k per colourful pages of pictures makes 450 MB equivalent to 4500 pages.) We still do not work on powerful algorithms that can rival with Adobe very recent standards in level of two or three GB or even larger files. Files of these sizes, are barely used by public. They could be high resolution scanned files of 600 dpi many of them concatenated already together. We also have not hardware resources to check if we can use "Dysprosium" PDF suite of ours to be used in traditional barrier of 1.5 GB. That should be checked with at least a dual core CPU (effective clock of 5.2 or more) and minimum of six GB of physical memory (in a 64 bits OS). Hence, if  an exception of "failed map" were thrown by very large files, it is likely due to lack of hardware resources thrown by native operating system, rather than my PDF merging software. [You might like to increase your Java "heap."

There are buttons in different places disabled for now. Their functions are under construction. Software will always remain free. "Free as we have in freedom and as we have in free beer;" quote from now a lost link on the Internet. We humbly become happy if we understand our work is of some benefit to other people and they are using it in ease. We have this powerful means and the related tools of communication thanks to millions of hours of free work offered by hard-working individuals all around the world.
