please how can i plot the Rosenbrock function to get the image above :here
To get the 3d plot at the top, click on the image in the WP article to get the image page. Check the bottom, the person who created the image was good enough to include the python script that created it in the comment section. It requires matplotlib (of course). As for the other images, it's hard to tell what's going on mathematically and there's no source given so I doubt anyone but the people who created them could reproduce them accurately.

I am working on Login with Tumblr in my application.
Everything is working fine, I am able to get blog name, access key and access secret key.
But not able to get the avatar of the profile.
I am using GTMOAuth.
Please suggest me how I can get the profile pic.
As per the documentation, the correct way to get a profile is avatar is to invoke
/avatar
In particular, you can get a blog's avatar in 9 different sizes. The default size is 64x64.
/avatar/512
would grab the URL of an avatar of 512x512
Reference: http://www.tumblr.com/docs/en/api/v2#blog-avatar.
You can use the URL to download/display the specific image.
But do you need something in particular?
Note There is also an SDK for Objective-C available on GitHub TMTumblrSDK.

This version is not production-ready yet but it should contain what you are looking for.

I want to make a Mac app to view and edit several GB sized binary files.
How do I start off? :-(
I thought I should begin with a simple scrolling hex viewer, but stuck already.
I think NSTextView is not the way to go. Because I only need to draw 255 kind of two character pair over and over. Also need to manage huge text data.
1) can I use NSLayoutManager drawGlyphsForGlyphRange method?
2) is it possible with NSTextView and clever text management?
3) or something else?
It will be greatly helpful if I could consult samples or demos.

Hex Fiend is an open source hex editor that can edit huge files (the website says it has been tested on a 118GB file).

Is it possible to read a text on an image?
Why yes and why not?
My client wants me to make this but I think it's impossible, if not impossible then it'll be very hard to make.. I was trying to explain it to him but it seems like he really wants to push it.
:/
EDIT: I don't understand why you downvoted this I was just asking a yes or no question here. :)) but well it's ok I want to hear what do you guys think if this is possible in vb.net
Use something like PDFSharp to get the images, then perform OCR on them with for ex. Tersseract.
Problem is where should that text be used? In the PDF? If yes it might be possible to include a textfield above the image with the text in the PDF, using PDFSharp too.
