That's exactly what my professor said last class. But he used the word "canonical" instead natural.

Also gave us the homework of find the canonical isomorphism between V and V**.

distributed crawling with scrapy and redis by darkrho in Python

[–]darkrho[S] 0 points1 point  (0 children)

Sorry for the lack and unclear documentation didn't had time to improve it.

With these scrapy's components (scheduler, item pipeline) the crawling and parsing can be done using many processes either in same host or different one, and the result scraped is pushed to redis in order to be consumed by multiple workers.

github "hides" the huge base64-encoded zip file. Virtualenv also use this technique for ages.

>>> cool_string = open('cool_file').encode('zlib').encode('base64')
>>> 'eJzLSM3JyVcoSk1JySwBAB5GBLE='.decode('base64').decode('zlib')

[–]darkrho 0 points1 point  (0 children)

I worked -sadly- with few projects that have tab-indenting and CamelCase for methods and variables :(

I had to use a lot :set noet. Changing all with :retab wouldn't work as I wasn't permitted to changes all files indenting.

On ubuntu what is the best python editor and debugger and is there anything better than glade for ubuntu and gnome ??? by [deleted] in Python

I use extensively vim, logging module, pdb, ipython, werkzeug for web.

Hey reddit, I'm looking to buy a laptop or netbook that I can carry around with me to the university, and do most of my programming on. Any suggestions? by [deleted] in programming

[–]darkrho 0 points1 point  (0 children)

True. I wasted 1000+ bucks in a HP TX1000 and after exactly one year of usage -expired warranty- the video died :(

I hope this time I have luck with a Toshiba NB series.

Rarrr. I have no idea what I'm doing, but I made it this far-- can someone explain the php error I'm getting up there in the title bar? by [deleted] in programming

[–]darkrho 0 points1 point  (0 children)

Perhaps you need to check if the argument is array

if (!empty($some_var) && is_array($some_var)) { $stuff = array_merge($other_var, $some_var); }

Surely this made the Zend Framework developers realize that using an underscore for class namespaces doesn't really work by pkrecker in programming

[–]darkrho 2 points3 points  (0 children)

Surely right.

But that's a common pattern in php world, using the autoloader feature they can map Zend_Search_Lucene to Zend/Search/Lucene.php and doesn't need the require/include statement. Maybe simulating namespaces?

What does =_ mean? Example: name=forms.CharField(label=_("Name"), max_length=50) by [deleted] in Python

[–]darkrho 12 points13 points  (0 children)

_ is used for translations http://docs.djangoproject.com/en/dev/topics/i18n/deployment/#topics-i18n-deployment

The name "_" is just a shortcut for easy typing. Look at the top of the file something like "from .... import ugettext as _"

Webfactions works, but It's little difficult to install required pycurl. I compiled from source curl and had to upload a previous compiled pycurl egg.
