People have wanted to know the size of Python objects for a long time, but before they had to dig into the source code. With the new function sys.getsizeof, you don’t have to.
Here are a list of sizes in bytes of common Python 2.6 datatypes. (containers are empty).
|
Type |
32-bit |
64-bit |
| int |
12 |
24 |
| long (1L) |

| float |

| tuple |

| dict |

| new class |

I’ve heard that its against the TOS to mention AdSense earnings, but I don’t think $0.00 qualifies as earnings (never mind, I can disclose “gross payments”).
The varying levels of $0.00. During this time around 5000visits were received.
I was hoping that I could use this to sustain the hosting, but at these rates, it could be 100 years before I see payment. I am now wondering if I should remove them but it might not matter anyway since about 40% of visitors use ad block.
At least my account hasn’t been suspended like Hizook. Or maybe the $0.00 is another way of showing it.

I had always thought that Reddit would be more resistant to the censorship that plagues Digg (such as the AACS ban and white-listing a select few sites that control 46% of Digg).
Unfortunately this was proved wrong today.

I recently posted 6 Stackoverflow reputation tips here. I knew there would be some criticism, but the amount of hate was beyond my expectations. There were people threatening to have me banned including one admin.
You would think that I was the Antichrist by some of the comments I had received.
I thank Jeff for diffusing some of the negative reactions here, but I think he must have received flack for it since he came out with this statement on Twitter and did not respond to my comment on SO meta:
the gaming stack overflow user has been discussed. But at 7 months, 68 questions, and 325 answers, who is gaming who, again? 
- Jeff Atwood on Twitter.
This same sentiment of Stackoverflow being the winner and me being the loser was also repeated here. It made me realize that I had not gotten the point clearly enough to them, so here I will try to re-explain my position.

Thanks to Donald Knuth, CS students and programmers know about Big O notation.
Unfortunately with all the years of academic brainwashing or glossing over, people think that Big O is all that matters and look at you funny if you dare to even mention substandard algorithms like linear search.
Formal Definition of Big O
Many people forget that M and X0 can make a big difference.
