Using PyCrypto with Spring Crypto/Spring Security Default Encoders

Spring Crypto Encryptor Details The Spring Crypto module is amazing. Secure defaults using standard interfaces really make it a pleasure to use, and with it being full tested and vetted, it also gives a develoepr the warm fuzzy feelings of nice Java security implentation. The standard interface is through the  org.springframework.security.crypto.encrypt.Encryptors class, defined (in version 3.2.0 here (the class API to which this blog post was written in July 2016). Spring Crypto uses AES256 encryption behind the scenes in its out of the box class setup; it's as easy as: In the above code snippet, the password  variable is a passcode, with the salt  variable used to create the AES key. It uses 256 bit encryption with the standard calls (depending on your JRE/Java Cryptography Extension (JCE) Setup, make sure to download the appropriate extension ). The default AESBytesEncryptor setup generates a 256 bit key (32 bytes) from a salted iteration done 1024 times. Another th

marking evolution and intelligent design

In late July, BBC published an article about the process from which one species of butterfly can divert from another. The article's main point is that two very-similar species of butterflies living in the same geographic area only mate with others of the same species based off of a small mutation which produced marks only distinguishable to butterflies of the same species.

"This has the effect of discouraging inter-species mating, thus encouraging genetic isolation and species divergence."

Which has always been one of the aspects of that I always found difficult: how could one individual mutate/evolve and then pass its modified genetic information onto its predecessors? How would its predecessors know to only mate with other evolved species? This article and study is very insightful in shedding light into that, and could be (speculation) the divergence between how fish became snakes became lizards became ????.

Of course, I found that article from /. when it was posted a few weeks ago. Of course, with the typical slashdot discussion, people started talking about the news and events of today rather than staying on the topic of the article, and while President Bush hadn't yet spoke out that should be taught in biology class, the discussion drifted over to Creationism's successor.

I don't want to ruin some of the discussion for people, but there seem to be a very intelligent minority over there, and one or two people often provide more succinct information in a paragraph or two about a topic than a media reported can with 5 pages of text. This post brings up ID, and amongst others, this post provides the clearest counter point about multi-animal 'intelligent design' done by the same 'author'.

I forgot to mention that this whole post was brought about from that butterfly article and the movie March of the Pengions; which was a story of craazy instinctual evolution.

As Morgan Freeman said March of the Penguins is a love story about penguins.

Regardless of that comment it had nothing to do with evolution. It simply followed the life of a mating penguin over the course of a year. You can hypothesize about the origins of the penguin or their mating process but it was not mentioned in the movie.

Also don't confuse Intellitent Design with a young earth Genesis literal translation believing Christian. They are not the same thing. Infact there are a great number of people, who believe in both ID and evolution. They are not contradicting terms.

just a quick XML note:
until you learn how to ramble on and on for multiple pages, you should not use the LFP tag. this post pales in comparison to a real LFP.

Spring Framework Sample Main Method

So my desk-mate* and I were having a conversation about an upcoming coding project, and he remarked how nice it was for someone, somewhere to post a complete sample on their blog for the spiders to index, so that he can find it. So I thought I would also, pay it forward and hopefully someone in like 2012 comes by and needs a sample main method using the spring spring framework for application level dependency injection. Everyone out there seems to have used the MVC and deploying spring based apps in a web server WAR file. Except for this link: Levarage Spring Web development with Offspring . [Offtopic: it uses classes in the com.offspring.* package, like the band's website !] It uses a simple bean file and a main method really close to the following snippet to instantiate (that's my new favorite word) the application using the spring context**: import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;

My Yahoo! Answers Science Post

I am my dad's personal Yahoo! answers person when it comes to things science and physics. So when I received a question on the dual nature of light and matter, I wrote him back a nice long (LFP!) email in answer. I thought I'd share. Question: Sound travels in waves and needs an "ether" for transmission. Light is also a wave but doesn't need an ether. Is light in space "wave" or "particle"? because when light bends do particles bend or this this one of the examples of light as wave? Answer: Sound is a pressure wave. It is the compressing of molecules. It is the compression that is the sound. Light is a wave of electromagnetic fields, fields in this case being force representations. The light wave is a constant of nature in which a electric force changing will produce a magnetic force which will cause an electric force in a stable, repeating way traveling forward. There are other places where electricity creates magnetic forces and v
