Comment on ToString Garbage Creation in C# by Gavin Pugh

Hi, I stumbled across this article from a web search.

A few months back I published some articles which delve into some methods to avoid garbage when working with strings. Particularly the ones you mention in this post; they would be addressed by using something similar from this:

Cheers.

Nice to know it’s here if I ever need it. I like the format of the listing too (fixed pitch, alternating shading).

Hey someone found a use for this?! Well, that’s more than I expected when posting it

Hey,

that was (nearly) excact what i was looking for. Had to write this for univerisity in Java. In the end my resulting code looks MUCH different and is not as fast as yours, but its still okay. Without your example I would have never find a solution (and it took only 3 Hours of try-and-error to understand, how it works ^^)

Thanks for sharing, man.

Can you be a little bit more specific?
E.g., tell me a sequence that this algorithm doesn’t work on.

I have verified this against a few million random strings which were solved using a more brute force approach, so I’d be surprised if there is an error.

Yo, this shit doesn’t fucking work

Hi,
Could you please add an explicit license for this code, or declare that you release it to the public domain?

Thank you,

You can trust the coefficients on wikipedia at the time of posting this. The coefficients I used in my python code are also correct, and mine have more precision (which won’t matter unless you use 64 bit floats).

Hi !

I am interested in the implementation of CDF 9/7 in RealBasic to use it for denoising pictures in my softwar SeamlessMaker (http://www.hypatiasoft.fr). I have already writen all subroutines it for Haar’s wavelets but the results are not very good. Can I use the same subroutines for CDF 9/7 just changing the High pass and lowpass filters ? Can I trust in these coefficients : http://en.wikipedia.org/wiki/Cohen-Daubechies-Feauveau_wavelet ?

Thanks in advance.
