What News About Dysprosium?

(For the latest PDF files Merger Software please have a look at the top of the left margin, inside the red box.) I promised a release of Dysprosium Suite before the end of this 2011. I could not eliminate a serious hurdle on the way. I could not find a PDF viewer that seamlessly joins to Java. I mean a free viewer. There had been an excellent free Java viewer by Adobe developed ten years ago. It means it is based at best on works started before the millennium. It works still perfect if your created PDF be of the type you might create by the latest LaTeX tools (such as MiKTex) or by Adobe Professional tools. It does not even load a blank page which is not created in this way. But most of the people use everything to create PDF; such as, Google Docs, or Open Office, and many scanner to PDF software. Such cases crashes the Adobe Java viewer. Adobe for unknown reasons did not continue the development of that software, and its present free software SDK is pure C++. I worked to switch to that tool but there is a further hurdle since this SDK utilizes MFC proprietary libraries and include files. I tested every available claimed free Java PDF viewer, but actually they all have a mistake. They are not Java Swing. Adobe viewer is a pure Java Swing. It is so malleable that you can give them the "group layout;" a very Java Swingish layout. But I had some minor success in pushing the limit of merge to astonishing 3GB in 64 bits versions of Windows 7 and Windows 8, with enough RAM memory. I had 8GB installed and put 4GB of it available for Java heap. CPU was quad core and never exceeded in 10% usage for each core. FSB was 1333MHz. This is the biggest PDF file you might find. The other reason that I did not switch to C++ is the belief that I have on Java programming. It is much more natural than C++. (I am a C language fanatic, but not C++) Well, C# is somehow Java. But it is not free, for full blood development. (It was a strategic mistake, in terms of nerds commenting, that Sun pushed against usage of Java by Microsoft. Otherwise, there could be more harmony in the present sphere of development tools.) Switching to C++, or to C# will change my work as a retired person to a full time professional developer. I am going to create a separate package with Adobe Java viewer with no guarantee of being usable on loading every PDF. I am going to develop one without viewer, besides. Please have a look at the snapshot.

It is a document created by the LaTeX (using MiKTeX). Book includes extreme fonts and sophisticated images. All 74 pages are loaded nicely. Yellow color has been used to create contrast for this demo. The next document is a one page document created by Open Office. Only one word is written on it. It dispatches error upon loading.

There was, another disappointment, too, in lack of much progress in breaking the password of PDF. I was interested in its mathematical side. A brute force multi threading could break a password of 5-character length created out of 64 characters in a reasonable time. Hence, we have "Remove Password" button (on condition that you have the owner's password) but not the "Unlock Password" button.

I have had 23000 downloads from 156 countries. Only 2 countries in South America (Paraguay, French Guiana) and 4 countries in Asia have not used Dysprosium Software, yet. The remaing countries not downloaded to this date(less than 30 of them) are from the central Africa.
