Reference Terms from Wikipedia, the free encyclopedia Entropy In thermodynamics, entropy is an extensive state function that accounts for the effects of irreversibility in thermodynamic systems, particularly in heat engines during an engine cycle.
The (Shannon) entropy of a variable is defined as bits, where is the probability that is in the state , and is defined as 0 if . The joint entropy of variables , ..., is then defined by See also Differential Entropy , Information Theory , Kolmogorov Entropy , Maximum Entropy Method , Metric Entropy , Mutual Information , Nat , Ornstein's Theorem , Redundancy , Relative Entropy ,...
Post   Topic   (x) Wed, 18 Jun 2008, 06:11pm #2 zzz Administrator As jrandom once said, I think, "i2p eats entropy for breakfast". I2P requires strong crypto so it must use something that can guarantee entropy (and therefore block). I am investigating some issues that occur in i2p when it does run out of entropy.

Serve local files in the docs/ directory, for CSS and images in error pages, using the reserved address proxy.i2p (similar to p.p in privoxy). This solves the problems with including links to the router console, as assuming the router console is at 127.0.0.1 leads to broken links if it isn't.
Your I2P router is not working properly! The domain proxy.i2p is reserved for the I2P router. In the Java I2P version, for example, the domain is used to support the address helper. If you just call proxy.i2p, the following message appears: "I2P HTTP proxy OK".

Our long list has an average length of 7.0 characters per word, and 12.9 bits of entropy per word, yielding an efficiency of 1.8 bits of entropy per character. Our short list has an average length of 4.5 characters per word, and 10.3 bits of entropy per word, yielding 2.3 bits of entropy per character.

More info: Issue #90 - Add support for smart crop . Valid strategies: entropy : focus on the region with the highest Shannon entropy . attention : focus on the region with the highest luminance frequency, color saturation and presence of skin tones.
In case you are tempted to question where entropy comes from. Consider that Entropy could just be described as the absence of everlasting things. The only way you'd get that was if change was impossible, but change clearly is.
Note: The client hints set for a particular origin can also be cleared by sending a Clear-Site-Data: "clientHints" response header for a URL inside that origin. Low entropy hints Client hints are broadly divided into high and low entropy hints. The low entropy hints are those that don't give away much information that might be used to create a fingerprinting for a user.
