areadiffractionmachine

The Area Diffraction MachineThe Area Diffraction Machine analyzes two dimensional powder diffraction data. It is free open source software. It is still in development so check back frequently for updates. What Does it Do?It displays diffraction data interactivelyLoad in mar2300, mar3450, marCCD ... [More] , tiff, and now edf diffraction data. Change the intensity scale or color map. Image Calibration Use the calibration tab. The program can calibrate standard diffraction images with inputted Q values. This calibration can be done with only the Q values and an initial guess of the calibration values. Calibration does not require manually clicking on the screen to find diffraction peaks! Masking This program can apply both a greater then or less than threshold mask to the diffraction data. It can add polygon masks to different areas of the diffraction data. Perform a Q-χ Cake the data Perform an Intensity IntegrationPerform a Q-I integration, a 2θ-I integration, and a χ-I integration. Automate the program with MacrosFully automate the program using a rich macro language. Runs on Mac Get ItThere are Mac and Windows executable of the program that can be easily installed. You can also run the program from source on Linux. Questions?There is a Discussion Group for the program at here. If you have any comments, questions, or suggestions, feel free to post them to the group by emailing area-diffraction-machine@googlegroups.com. If you have any issues with the program, please submit them to the issue tracker. [Less]

python-xrd

A python library which contains functions and classes useful for scientists and/or developers who deal with x-ray diffraction calculations.

webfinger

What?WebFinger, aka Personal Web Discovery. i.e. We're bringing back the finger protocol, but using HTTP this time. BackgroundBack in the day you could, given somebody's UNIX account (email address), type finger email@example.com and get some information about that person, whatever they ... [More] wanted to share: perhaps their office location, phone number, URL, current activities, etc. The finger protocol, sadly, died. Fast-forward to Web 2.0. We're currently bickering about how we do interop between all these social web services, and even how we represent a person's identity. The two main identity identifier camps are email addresses and URLs. Let's review the pros and cons of both: Email address URL People associate it with... a person usually a thing, place, or document; sometimes a person Is readable? - X Is writeable? X X People have been trying to use URLs as identifiers for people (as OpenID does), as it has great readability/discoverability properties, but this effort has largely failed because of UI/UX design failings, user confusion about URLs, etc. It's now increasingly accepted that email addresses would be good identifiers for people (since that's what people are used to already, and have on business cards and in their addressbooks, etc.), but we're back to the original problem that email addresses are write-only. If I give you my email address today, you can't do anything with it except email me. I can't attach public metadata to my email address to give you more information. WebFinger is about making email addresses more valuable, by letting people attach public metadata to them. That metadata might include: public profile data pointer to identity provider (e.g. OpenID server) a public key other services used by that email address (e.g. Flickr, Picasa, Smugmug, Twitter, Facebook, and usernames for each) a URL to an avatar profile data (nickname, full name, etc) whether the email address is also a JID, or explicitly declare that it's NOT an email, and ONLY a JID, or any combination to disambiguate all the addresses that look like something@somewhere.com or even a public declaration that the email address doesn't have public metadata, but has a pointer to an endpoint that, provided authentication, will tell you some protected metadata, depending on who you authenticate as. ... but rather than fight about the exact contents of that file, WebFinger is about making that file discoverable at all. The community can explore and innovate within that discovery file later. [Less]
