Py3K - PEP 355

So, we still don't get object oriented path manipulation in Py3K

$ python3
Python 3.1.1+ (r311:74480, Nov  2 2009, 14:49:22)

Type "help", "copyright", "credits" or "license" for more information.
>>> import path
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named path
>>> 

Is there still hope?

OK. Pronouncement: PEP 355 is dead. The authors (or the PEP editor)
can update the PEP.

I'm looking forward to a new PEP.

PEP 355 died out years ago, but the reference implementation still exists, and IMHO is still garbage.  Will there ever be another attempt at a stdlib PathClass?

Happy Daddy!

How vain am I?

Thanks to alextreme, lbruno, and clayg.



Yeah, that's MY bug fix in your django 1.2 (currently in beta, get your official copy March 9th!)

The really sad part is, it's not even really MY code change, not REALLY.  I just re-compiled some other guys patch as a top level diff and updated the tests... but I'm still TOTALLY jazzed about being the last submitter before the final commit.  Wait, is that vain?  Or just totally lame?

Python over-riding options with ConfigParser and OptionParser

It looks like it may be woth looking into argparse (non-standard library)

"""
The basic idea is that config information can be pulled out of

* Global config file
* User local config file
* environment variables
* command line

Higher priority comes later in the list. 
"""

But here's an implementation of cascading config file/command line options with ConfigParser and OptionParser - without subclassing.

Basically you just...

• Set global defaults in at the top of the module in the constants section
• Use those to set defaults in the config object
• Read in the config file possibly over-riding defaults
• Read out the values in the config object to a dictionary
• Use THOSE values to set the command line defaults

Then you can get any option you need out of the command line options argument

It's not very flexible, but it uses standard libraries and should be fairly  obvious.

from ConfigParser import ConfigParser

    # config_options is dictionary of strings, over-ride toggle to bool

    (options, args) = parser.parse_args()

    print "option: %s" % options.option

        print "toggle is ON"

        print "toggle is OFF"

vuze torrents get more peers

When I only had one or two torrents going at a time they seemed to download slower than my connection should have been able to support.  I was looking for ways to maximize my torrent download speed when I found the setting for "maximum number of connections" under options in Vuze.

Please note all the details here have only been tested to work to improve download speeds of freely distributable copyleft materials such as Ubuntu full DVD images.

If you're like me, you've already covered the basics (I had "green smiles" and "open nat") but if not, you may want to start with that.


My problem was that I was only connecting to 20-30 peers out of thounds of seeders and my down speed for a single torrent capped out around 150-170 kB/s.  I discovered that the max number of connections was set to 40, I don't remember changing it - hitting reset seemed to indicate that by default Vuze limits the max number of connections to 50:

 

This number maps directly to the number of peers in your swarm.  And mine was set much lower than the recommend "Good Settings" - I went ahead and just disabled it for now:

And I was pretty happy with the results:

post code snippets in google blogger

Howdy folks, here's some code:

def myfunc(*args, **kwargs):
    for arg in args:
        print arg
    for k,v in kwargs.items():
        print k,v 

First thing you need to do is make sure you're useing the Google Blogger's "Updated Editor".

1. Log into Blogger, and from the Dashboard goto Settings.
2. On the Settings tab, down towards the bottom under "Global Settings"
3. "Select post editor" - "Updated editor"

The updated editor actually solved a lot of the "problems" I was having with pre formatted text getting messed up when I went back and forth between compose and edit html.

But to post some really good looking source code you have to use SyntaxHighlighter.

SyntaxHighlighter is written in JavaScript, and there some css styling as well. To use SyntaxHighlighter on your google blogger page, you have to edit the template.

Under the Layout tab, go to "Edit HTML"
In the "Edit Template" box, scroll down toward the bottom.
You want to add the .js/.css references just before the last closing head tag (</head>):

<link href='http://alexgorbatchev.com/pub/sh/current/styles/shCore.css' rel='Stylesheet' type='text/css'/>
<link href='http://alexgorbatchev.com/pub/sh/current/styles/shThemeDefault.css' rel='Stylesheet' type='text/css'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shCore.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushXml.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPlain.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushCpp.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJScript.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushJava.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPhp.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushPython.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushRuby.js' type='text/javascript'/>
<script src='http://alexgorbatchev.com/pub/sh/current/scripts/shBrushSql.js ' type='text/javascript'/>

SyntaxHighlighter makes it easy to copy the above snippet - just hover over the code, and click the "copy-to-clipboard" icon:

Then at the very bottom, you also want to set some global parameters just before the last closing body tag (</body>):

<script language='javascript'>
SyntaxHighlighter.config.bloggerMode = true;
SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/current/scripts/clipboard.swf';
SyntaxHighlighter.all();
</script>

 You can then make highlighted code by wrapping your code snippet's in a
<pre> tag with a specially formatted "class" attribute, like this:

<pre class="brush:js">
alert("Hello world");
</pre>

Result:

alert("Hello world");

You can add brushes for different languages by adding more JavaScript files to your Template. The author hosts the most recent version here:

N.B. Just because you put html inside a  <pre> tag doesn't magically make html parsers know you're try to post literal HTML code - you still have to escape valid HTML using &lt; and the like or it won't be rendered correctly.  Try something like this.

I cobbled together the following steps from these sources:

Using SyntaxHighlighter on BLOGGER
Publish Source code in Blogger

Newegg Shipping Halo: ODST early

I pre-ordered from Newegg, and it arrived Monday Sept 14th.

Play'd it through the first night on Heroic (6 hours).
It was fun.
No dual wielding.
No battle rifle.
You move surprisingly fast with a turret.
No match-making for firefight (yet?).

Halo: Mythic is a separate disk, with:

• Matchmaking
• Custom Games
• Theater
• Forge

...and ALL the multilayer maps.

Heretic is Midship.
Cathedral is like Epitaph, but VERY symmetrical.
Longshore seems pretty cool.

You play them off Mythic, you don't download them to your HD. Your Halo3 saved content is available from with-in Mythic automatically.
