wxpython + ogl

[Andrzej]

Hi!

I'm writing a simple digital circuit simulator in order to familirise with 
(wx)python. I thought it would be an easy task with help from ogl lib. After 
a not so brief encounter with wx specs I've started to code but I just can't 
figure out how to get user-defined attachment points to work. I've tried to 
call SetAttachmentMode(True) for shapes that should be connected and then:

dc = wx.ClientDC(self.canvas)  # ->self.canvas = ogl.ShapeCanvas(self)
self.canvas.PrepareDC(dc)
shape1.MoveLineToNewAttachment(dc, line, x1, y1)

But the line pops up in random place and is changing it's position only 
vertically when moving one of the shapes. I'm probably doing something 
terribly wrong and I'd appreciate any help to solve my little problem . 
Thanks in advance

Andrzej

Re: Holding until next value change

[andrzej . brozi]

Hello

Perhaps this would suffice:

prev = None
for value in main_call():
if value==prev:
pass
else:
prev = value
if prev>0:
print('+v')
elif prev<0:
print('-v')
else:
print('0')

Of course this will work only if subsequent values are exactly the same.
If not - then "value==prev" should be replaced by some other test (for sign or 
for proximity).

Regards
Andrzej Brozi

Re: [oi-dev] DTrace probes in Python 2.7 (and next 3.3)

[Andrzej Szeszo]

Hi Jesus

Just noticed that there is a python 2.7 package in Oracle's userland 
repo here:


<http://hg.openindiana.org/upstream/oracle/userland-gate/file/ea6a3f09379c/components/python/python27>

It includes DTrace patch. Did you see/use that?

Hi all.

I have spend some time trying to integrate DTrace probes in official
Python: Currently I have a patch to python 2.7, and my plan in to
integrate officially in 3.3.

The initial probes were based on previous work from OpenSolaris, and
similar, but currently I have quite a few more probes. Current details
in
<http://hg.jcea.es/cpython-2011/file/b1a39702dfd8/Doc/library/dtrace.rst>

The probes are tested under Solaris 10 x86 and x86-64. I would need
somebody to try on Solaris 10 Sparc (32 and 64 bits), Solaris 11,
OpenIndiana, FreeBSD (seems to need a kernel recompilation to enable
user mode tracing, check Google), Mac (I doubt it works as is), etc.,
any other platform running DTrace. What about SystemTap compatibility?

Details:<http://bugs.python.org/issue13405>

How to check:<http://bugs.python.org/issue13405#msg147706>.

The easier way to get the patch is to clone my repository at
<https://hg.jcea.es/cpython-2011/>  (with mercurial) and move to the
branch "dtrace-issue13405_2.7". Keep the clone around if you plan to
try future versions of this patch, including the future 3.3 version.

You can manually apply the patch in
<http://bugs.python.org/file23758/a9f4ae43fd85.diff>  to python 2.7.2+
sourcecode. The patch is developed against version 3c3009f63700
(2011-11-14). It might not apply cleanly to 2.7.2 sourcecode (not
checked). I will provide a direct patch to 2.7.3 when available. Maybe
to 2.7.2 if there is demand.

This is still work in progress. I will improve support with your
feedback. I am considering probes to monitor GIL and thinking how to
monitor C function calls from Python in an easy and fast way. Feedback
very welcomed.

Please, if you care about this, test it and provide some feedback :).

PS: Better post feedback in the bug tracker that by personal email :-).

Does not Visio meet your requirements? It's quite powerfull UML design

Yes, sure. There is mySQL server installed. I can access it from php.

How can I install them? Is it so simple as uploading module files to 
cgi-bin directory? Metakit (http://www.equi4.com/metakit/python.html) 
database works this way, but i haven't tested it yet.
