I've completed writing all the demos and most of the documentation for 
my soon to be released vector graphics and physics simulation library. 
The library is named Tiny Sim and the first version will be published 
soon. I have lots of planned features and improvements to come.


If you are interested I posted a very brief overview page and a video 
containing all nine demos for my library on this web page:

Re: [Lazarus] Lazarus 2.0.10 corrupted by Win 10 crash, how to repair?

Grateful for any suggestions on how to fix this.

(I do not really want to start over from scratch after spending time
installing extra packages and customizations and the like).

The packages should be OK. But as the names indicate, your input history is
lost, and the environment options (essentially what you entered in tools -
options) also.

Just delete those 2 files.

Thanks Michael,
after doing that Lazarus starts up with the after-installation-dialog
where one can check the important paths etc.
Then I got to a pristine Lazarus but with my editor configurations
intact and the installed packages still there.
I could successfully build my project and run the resulting exe.
My custom desktop was gone so I re-created it and saved it.

I guess the custom desktops are saved in environmentoptions.xml...

Lesson learned:
---
This is the second time Windows 10 crashed and trashed the
configuration fles, last time when using Lazarus 2.0.8.
 From now on I will make a backup copy of all of the files in the
config dir into a zipfile so I can resurrect a broken file after a
crash.

Rant:
-
This thing with Windows crashing never happened in the many years I
used Windows 7, but in Dec 2019 I had to finally move to a new
notebook and of course now Win 7 is no longer available so I have Win
10...

And that has caused all kinds of problems like the crashes I discuss
here but also a self-initiated reboot at irregular times purportedly
in order to "upgrade" the system
And I have found no way to stop it from happening.

Win10 also triggers a start of a system backup at non-scheduled times
for unknown reasons. I have a scedule set for a backup to run on the
night between Friday and Saturday every week, but now it can start any
day at any time
Soo strange.
When writing this I realized that I could of course have used the last
backup to get my original config files back, but I did not think as
far

I wish I could bring back Windows 7

Of course on Linux this is not an issue at all, but if the target
programs are supposed to run on Windows I have no choice here.


I use Lazarus 2.0.10 for Windows installed over Wine in GNU/Linux and it 
works ok,


even for some projects I share the same source tree, and I'm able to compile

for the two platforms.

Re: [Lazarus] TSql57 replacement

[Mario Guerra via lazarus]

Recently, in a project I used Zeos 7.2.6 to connect to MariaDB 10.3 with 
protocol "mysql".
Zeos uses (for every database) the native client libraries, so, in Linux 
you only have to install the proper client to MySQL or MariaDB.

Hope it helps, Mario
