Fake Account … Fake Account … Fake Account … Fake Account …
Within a day or two I receive such mails from SiliconIndia.
This is the snapshot of mail I receive every now and then. Every time there is a different “girl” who is sending invitation. And every time I don’t know her. Its definitely coming from some fake account.
I don’t know whether such mails add any traffic to siliconindia.com, but I am pretty sure that such mails annoy user.
As the title suggest this post is regarding “Memory Requirement of django ORM”.
Actually some days back I myself faced this problem and wrote “Why Django ORM Sucks : It takes a hell lot of memory in processing“. From various comments and a thread which started on google groups, I came up with few points one should check while operating on large amount of data.
For showing points i’ll use following example:
for r in UserRating.objects.all(): ratingDict = cache.get(r.movie.id) if ratingDict is None: cache.set(r.movie.id, [(r.user.id, r.rating)], 86400) else: ratingDict.append((r.user.id, r.rating)) cache.set(r.movie.id, ratingDict, 86400)
So here are the mistakes in previous code.
The syntax to add it in Model is:
class MyModel(models.Model): video = FileField(upload_to=None[, max_length=100, **options])
Here upload_to is local filesystem path that will be appended to your MEDIA_ROOT setting to determine the value of the url(mymodel.video.url) attribute.
If,
MEDIA_ROOT = ‘/home/myname/files/
upload_to=’videos’
file: abc.flv
results in: /home/myname/files/videos/abc.flv
where as if,
MEDIA_ROOT = ‘/home/myname/files/’
upload_to=’/videos‘
and file : abc.flv
result will be saved in : ‘/videos/abc.flv’ (i.e., root directory of filesystem)
You can also set upload_to=’videos/%Y/%m/%d’.
After months of speculation, the Filmfare nominations are finally out. Time to see who will take the ‘beautiful dark lady’ home this year! Will act in Rab ne.., happy and ‘gay’ Dostana or 8-packed Aamir Khan?
Even as the stars get ready for the big night, stay glued to get all the inside dope and starry controversies surrounding the event. So, who are you betting on this year?
Dostana
Ghajini
Jaane Tu… Ya Jaane Na
Jodhaa Akbar
Rab Ne Bana Di Jodi
Rock On!!
For a project i wanted to keep one of my table in memcache. I tried to do it using Django ORM but it was taking a hell lot of memory.
Let me tell u some details.
Table Structure : This table has almost 1,300,000 rows
| id | movie_id | user_id | rating |
| 1 | 1 | 1 | 5.0 |
| 2 | 1 | 2 | 4.5 |
| 3 | 1 | 3 | 4.5 |
| 4 | 2 | 1 | 3.5 |
| 5 | 3 | 3 | 2.0 |
All I wanted was to keep them in cache(memcached), with following format:
memcache Key : movie-id
memcache Data : [ (user1:rating1), (user2:rating2) ]
for r in FlixsterUserRating.objects.all(): ratingDict = cache.get(r.movie.id) if ratingDict is None: cache.set(r.movie.id, [(r.user.id, r.rating)], 86400) else: ratingDict.append((r.user.id, r.rating)) cache.set(r.movie.id, ratingDict, 86400) del ratingDict
In this approach for processing every 1000 it was taking some 5.1 secs.
For a project I needed Memcached. But the problem was that I have my development system on WindowsXP.
When I Google I got various links to install Memcached on windows, but there wasn’t any link that tell all about Memcached with Django on Windows
So Here we go:
While visiting various sites (specially those fucking Raja Sen Movie reviews), I at times need dictionary. When I don’t know meaning of any word I have to open dictionay.com and than search for it.
So, to get a solution of this is came with a Bookmarklet, which opens information bubble on double-clicking on any word in the page.
But to launch dictionary you have to click on this – Dictionary : DblClick
Bookmark above link for future use.
Example : The meaning of “Reference†is shown in a small bubble.
Yesterday I was hacking the source code of a website. While doing I needed the javascript library being used in that site.
Although on accessing various javascript files i came to know that Prototype was used in that site.
Later I came to know about a bookmarklet : WTFramework. Just add this to on your bookmark.
Just click this bookmark whenever there is a need to know the JavaScript frameworks (MooTools, Yahoo User Interface, jQuery, the infamous Scriptaculous, Dojo Toolkit, Mochikit, etc..
Valentine’s Day or Saint Valentine’s Day is a holiday celebrated on February 14 by many people throughout the world. In the West, it is the traditional day on which lovers express their love for each other by sending Valentine’s cards, presenting flowers, or offering confectionery. The day was originally a pagan festival that was renamed after two Early Christian martyrs named Valentine.
The day became associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished.
