font-family:Arial'>First of all, I just had an altercation with my outlook –
so I I’m a bit disorganized now – ugh – But I wanted to thank
Mark who suggested the Linux fpNanoSecond function and the feedback from Micha.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Additionally, the suggestion to help the Free Pascal Team on
things like the Smart Linker – I consider it an honor – even if it
was in jest. I’m such a die-hard fan of FreePascal. I spend hours, days, months
at a time – totally immersed in it. A Master? Hardly! </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In my last email couple emails – I first posted to ask
for help – for something like the Win32 Sleep in linux - which I
was told about the sleep function now being implemented in Linux sysutils –
but – I was looking for something more along the lines of the operating
system’s sched_yield function in linux – Why? The size of SysUtils
add a big amount of heft to my applications in Linux and in Win32. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I explained how one application I’m doing –
needs a small foot print and needs to be able to yield, and how in other stuff
I’m doing – size doesn’t matter. (This is where the
recommendation to help the FPC team on with smart-linking on Linux came in with
a smile… and in response – I’m swamped but am planning on “giving
back” .. I have honorable mention of FreePascal, Lazarus, and MySql on my
“not ready yet – no time) .org site: <a href="http://www.jegas.org/">www.jegas.org</a>
By the way, I’m not the worlds best web gfx guy – but that web site
is totally freepascal. Each page – it firing FreePascal Code in Linux AN
was/is developed in Win32.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I was Talking a a bit about how I’m experimenting with
TThread, and how I basically have a “Windows OS” or Lazarus
Application structure – in that it has a messaging system like windows GetMessage
and DispatchMessage, and how all my classes have a similar base architecture that
makes them really work together versus fighting with them all the time.</span></font></p>

font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have basically made a working multiplexer and that is why TThreads
has caught my attention. Everything I’m doing runs in Linux and Windows –
and if it doesn’t – its on my long to-do list. This multiplexer that
has a console GUI that is totally homegrown and has its own look – but is
not far off from FreeVision or Dos Edit’s console windows except I wrote
it from scratch using the CRT, Mouse, video, and Keyboard units that come with FreePascal
This GUI is built on a wrapper I made for thiese console units called
simply CONSOLE. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have experimented with TThread, and I have found that in
my code anyway – it seemed to run in a serial fashion and not as a
separate task. I forgot what led me to believe this – most like a log
file that recorded stuff by simply appending a text file – and using the
output to tell me what cam first… but I digress. The truth is, I don’t
have an intelligent reason to tell Micha about – because I don’t
remember – more importantly – its was probably something in my
code. Lets not forget I said I was just starting to play with it. That means I’m
definitely just learning – so TThread is probably just fine – and its
me.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>It does seem appropriate to me that multi-threading is
something I definitely will want in my system – but I also very much
believe that well designed multiplexing systems can out perform threaded
systems – in many cases. Multiplexing: Need main loop that efficiently
handles and delegates work in small pieces, more or less emulated “multi-tasking”
without overhead of creating and swapping threads tasks in and out. This
requires a discipline from the “hello world” to the system roll out
that intense if you want to keep things running smoothly and not let the miles
of source code run away from ya.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Threading is great for many reasons – like parallel
stuff, fire and forget stuff, “Here Kid go ask that server for some data…
let me know when you have it” … so the flexibility of threading –
and the scaleability – make it really awesome.</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m still learning – always learning – but
as I’m moving toward this threading business – I keep finding a
certain amount of validation for the multiplexer architecture – in that
only through it – does it SEEM to me that I can do a logical approach to
handling/managing the threads. By maintaining them in the main loop of main
app, house cleaning – commandeering them to suspend, resume, or
whatever as necessary – I really (as a parent my self) think of the
multiplexer as the parent process, and the threads – children –
that – yes they can do what they want – but only under supervision </span></font><font
