I played again a little bit with networking things, especially on different platforms. Very nice that the most sources now compile out of the box at Linux, AROS, Amiga and MorphOS only very little ifdefs inside, and even they could be omitted by extending the Amiga-like-RTLs with some unix functions.
I wrote a little Lyapunov calculation program which sends the pixels to calculate via network to other computers to let them calculate. Lyapunov is very good for such things because it has very little inputs and results but rather long calculation time per point.
I compiled and run the client for all platforms I have available currently:
- i386-AROS (Linux Hosted – AMD FX 8120)
- powerpc-MorphOS (Mac Mini)
- m68k-amiga (Amiga1200 68060/50)
- x86_64-linux (AMD FX 8120)
- i386-linux (Intel Atom 230)
- arm-linux (Raspberry pie 1)
All compiled from the same source.
The Server and Image Viewing is done at AROS.
The power of Freepascal/Lazarus at its very best.
The white pixels are already send to some client but the result is not arrived.
The image is flickering a little bit (therefore in the movie sometimes no image to see) because I didn’t care much about the image plotting. I’m not sure why the image is flickering maybe the network communication take too much time so not enough time to draw the image.
The Hex Editor slowly gets into shape. Most important function, editing and Value showing. The Value is automatically showed in different types (as Byte, Word, LongWord, QWord) and even more important both endian styles(Big / Little). Later will insert also a function to insert a value as the combined types in both endian styles. For now I only need it for small files, so I load the complete file to RAM and then show it. Later maybe I make a viewer version for very big files, which work directly on Harddisk. But at the moment its not needed.

At the moment I need a HexViewer and sometimes also a HexEditor but even at Linux I’m not very satisfied with the functions with the available HexEditors. So I decided to write my own, of course I write it for Linux/Windows (there I need it) but now I always care about that it will also work for AROS. So I compiled it for AROS as well and it worked without any additional actions. At the moment its just a HexViewer. (use cursor keys for move the cursor, page up down to scroll a page, home and end jump to start/end, Tab change binary part to char part)
But I need Editing, search and replace and jump to special positions.

I played a while ago a funny tiny game on my phone called 2048, really easy concept but makes fun to play. So I wrote an own game for AROS which is inspired by it really easy and nice to program.
Its called BinShifter Bin because of Binary numbers which results from it and shifter because you have to shift the blocks around. With the arrow buttons or cursor keys you shift all blocks to one
direction. If two blocks with the same number are stacked in this direction they are added together and you earn points. The maximum number for one block is 4096 (like the numbers of colors
of the original Amiga ;-)). The game ends when no movement is possible.

Worked a little bit more on the sqlite3.library for AROS to use in freepascal. Its more or less only diligent working, and take care not to mix up anything. I didn’t include all the functions only the most important until now (at least what I think is most important) until now its already 106 functions inside the library.
Now I tried some test codes… the one from fpc directly are rather boring, even less impressive than my own examplecode.
But I found a german Tutorial how to use databases in Lazarus, with some tiny changes in in Lazarus component it compiles really nicely and works as expected.

Left side Linux, Right side AROS.
Played around a little bit with graphics and game mechanics. Result is (until now) a Pipe-like game just for fun.
The SynFacialHighlighter seems not to work on AROS, because no WideStringmanager is available, one way would be to write a Widestring manager (maybe would be good idea to do so also for the basic Freepascal implementation) or search for a different customizable highlighter. I found already one (included in Lazarus) SynUniSyn. The main problem is that this is just a very basic port from the delphi SynUniSyn and the original SynUniSyn is very hard to find (at least the original Pages are down, and sourceforge and so on are empty), so no Highlighter example files available. But I found a very old source of an editor wich have in an older repository version the sources and 311 (!!) Highlighters included.
So it works, also on AROS, maybe some tiny changes must be done, for example the C++ highlighter turns everything into uppercase. But this could be done I think, I will play a little bit with it.

Finally go LazPaint somewhat working, yesterday was just with many dummy functions in the bgrabitmap package. Today I wrote some implementations of this. It works, but it is VERY slow, because the drawing functions like WritePixelArray are very slow when drawing to a ARGB Screen. Maybe a clever conversation before will improve it. the other thing: it crashes very often, mostly List exceptions, I’m wonderring if thats the same as I got for EdiSyn, some fonts are too small to read.
I played a little bit with the TAChart, omg so many different units needed, so many components/pathes to set. Some inital drawing problems, some more error checking need. Now works nicely, of course some events and so on does not work.
This new TAChart is very different as the one I used long time before in my programs in university. So I’m not sure how to use this but in principle it works 😉
Made a little test program afunction plotter:
