I like OpenGL. Unfortunately, I can't seem to get PyGLet to work, even though the pyglet.org front page claims that "the major 1.2alpha1 release brings pyglet to Python 3." I followed the links to this page: https://code.google.com/p/pyglet/downloads/list?q=1.2alpha1 I installed pyglet on my Linux system's Python 3.3 using distutils, as I have done with many other packages. But I can't run test.py, nor can I even get as far as importing pyglet from my Python 3.3 interpreter command line. The obstacle is apparently Python 2.x-style print statements, which are found throughout tests.py and pyglet/__init__.py. Does anyone know an efficient way around this problem? Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Re: Beginner - GUI devlopment in Tkinter - Any IDE with drag and drop feature like Visual Studio?
There is the matter of how much time you want to put into this. There is the standard gtk library for python, and in the future, as soon as I'm well enough to focus, having recent problems, I'll be using the blender game engine to enhance my software to a 3d graphical form...to make my apps pop. So which tutorials are you willing to take time with, and which are benchmarked the best for your apps? For a 3d trig/quadrant cartesian 3d implementation for practice refresher, I used tkinter, and when using it was slow as hell. SO the question is, have you looked at the individual graphical tutorials for each, and decided on a look, a feel, and a time enhanced optimization yet? In other words, work a little bit with each to see which best fits your needs. -- http://mail.python.org/mailman/listinfo/python-list

Instructions for solving your problem can be found here:

Although it is written for Java, the same ideas will work for Python or

First, just what do you mean by "make file"? You refer to cmake, make, and .mk in three places in your message. How about a link to the actual tool you're interested in? And a brief list of the other tools you're using it with. Is this it? http://www.cmake.org/ Once we're talking about the same tool, then the question is what "elements" are you interested in? If your cmake is anything like the traditional make program, the format is deceptively simple, and enormously complex in usage. But I suspect that your cmake has very little to do with Unix make tools.

noticed it sailing past the max number of entries, so put in the print

BOFH > attitudes simply aren't going to change that reality. Is your job on the line if the sender of that email got the recipient's address right? Is your job on the line if the sender mucked up his SMTP settings and the message didn't even get to your server? Is your job on the line if the email never even got sent? Then why should your job be on the line if the sender violates his own declared protocol? Remember, if you don't publish an SPF record, your emails will be accepted regardless. It's only if you explicitly create that DNS record that ends with "-all" that any of this will happen - which means you *asked* for that mail to be rejected. If you do that and then send mail from a different IP, then I *will* reject it. Accepting mail and just giving it a spam score is *worse*, because the sender won't even know why it didn't get through (what if most of his mail gets accepted, but that one email when he sent a blank body, subject "RE: your invoice", and a zip file attachment, managed to trip the spam cutoff and get dumped?), whereas rejecting will result in a quick and easy bounce, probably within seconds (minutes maybe). I stand by SPF checking. It has never been a problem. If you don't stand by protocols, you weaken those protocols. And speaking of protocols, I'm now going to have to follow the "I'm on an airliner and mobile phones have to be turned off" protocol, as the flight's due to depart shortly.

This is well and > truly off topic now for the python list, though. And yet off-topic does happen... For what it's worth, here's how my server is set up: 1. A variety of protocol-level checks. If you don't say HELO, for instance, you get rejected. Surprisingly, these simple checks actually keep out a lot of spam - but I've yet to see any legiit mail blocked by them. (Not that I keep logs of these any more. I stopped watching after it looked clean for a while.) And if legit mail is rejected, it'll be resent or bounced by the sending MTA anyway. 2. SPF checks on the MAIL FROM:<> address. Again, if legit mail gets rejected (which would be the fault of the sending domain owner), the server at the previous hop will deal with it. Only hard failures get thrown out; anything else just gets marked (which we usually ignore) and delivered as normal, not even spam-scored. 3. Bayesian spam filter, set very conservatively so we get false negatives but (almost) no false positives. Any spam that gets through these three checks gets delivered, and then the users will drop it in their junk folder. Every week I do a train-and-wipe run across all junk folders, which logs spam counts from our primary mailboxes. Last week's run was 228 spam across the six logged accounts (some of those accounts collect from many addresses), or an average of five false negatives per account per day, and false positives are almost completely unheard-of. Considering how much spam assaults the outside of my fortress's walls, that's a fairly good ratio, I think. SPF for the win. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

My mail server did a number of things: 1. ensure IP address of sending server has a reverse name (domain didn't particularly matter) 2. ensure the HELO address in SMTP matches IP address of sending server 3. check sender IP address against spam blacklists, which includes netblocks of home ISPs, some entire countries, flagged subnets 4. greylist sender IP if the recipient requested it. First connection always fails with a nonfatal server error, next connection must wait at least 5 minutes. If a reconnection happened too quickly, the IP was temporarily black listed. After success, IP address is whitelisted for a time. A commandline MTA will not be able to get through greylisting; only a mail server with queuing could. Spambots tend to give up on the first error, even now. Cheaper targets I guess. 5. spamassassin checked SPF (DNS) and domainkeys (message itself) and weighted the spam factor accordingly I think there were other basic rules that sendmail applied to the sender, but I can't remember all of what they are. This is well and truly off topic now for the python list, though. -- http://mail.python.org/mailman/listinfo/python-list

Query Reverse DNS for IP > 2. Find domain > 3. Query DNS for MX > 4. ? There are a variety of things they check. They've got lists of IP address blocks that they know are residential DSL/cable customers, and sometimes they'll reject mail from those regardless of what you do. Some will compare the reverse-DNS lookup with the headers to make sure you're being honest about things like return-path, some will compare the IP address with the MX record for the domain they got when they did the reverse-lookup-DNS, and they've all probably got a variety of other secret heuristics they use to generate a "SPAM" score. For many years I ran my own SMTP server and had it configured to deliver mail directly to recipients. About 10 years, I had to give up on that because so many SMTP servers were rejecting/ignoring mail I sent. And I did have a static IP with a valid domain and MX record. But it was a residential DSL IP address, and I suspect that was enough to get mail rejected by some servers. -- Grant Edwards grant.b.edwardsYow!

If legit mail is rejected for failing an SPF check, it's the sending admin's problem, not yours. You should never have problems with it if it's set up correctly. And since rejected mail gets reported to the transmitting MTA, you don't need to drop it in a spambox or anything. It's not spam, it's simply invalid mail (equivalent to something sent to a dud address). ChrisA -- http://mail.python.org/mailman/listinfo/python-list

Yes setting SPF records will help your mail be accepted by other servers, but I disagree with your appeal to make mail server SPF handling as strict as your server does. SPF has problems in a number of situations which could cause legitimate mail to be rejected. In my last job I could only use SPF as one spam factor, not as a basis for rejection. -- http://mail.python.org/mailman/listinfo/python-list

Correction: "With Debian-based Linux distributions, you can etc etc" - aptitude is Debian's package manager, it's not something you'll find on other Linuxes. And the exact packages available depend on your repositories; again, most Debian-derived Linux distros will most likely have ogg123, but it's not guaranteed. However, it's reasonably likely that other package managers and repositories will have what you're looking for. ChrisA Good point, Chris. I do not want to make coding specifically for each package manager for many of the different distros. I follow the KISS princlple (Keep It Simple Stupid) when programming. Making a cross-platform/universal way to play an ogg file is better than being specific for each individual system. Remember KISS. Mahalo, DCJ -- http://mail.python.org/mailman/listinfo/python-list

It should be able to do what you want. There's also pyaudio, which is more

more.
Thanks Stefan! I have not heard of Pyaudio; I will look into that. As for
Pygame, I have not been able to find any good documentation for playing
audio files.
A quick duckduckgo search gave me this, at least:

Plus, I recently learned that Pygame is not Python3 compatible.
Looks like it's your lucky day:
