2015-11-26 BibApp working version

The goal of this 3-day sprint is to have a functional prototype of the BibApp

Results:

Working version running
Book info pop-up
Usability testing, and fixing discovered usability issues
- Improve book-info
- close book-info on back-button
- mention in text that books can be moved from background to foreground
Layout:
- extra line of background books
- fewer foreground books, to make background books more visible
bugfix – did not work in non-current browsers, ie. iOS 9
network-performance improvement
data dump with only books that have covers – ready for elastic search
- updated/made search engine service
begin working on bibapp-report
use bogpriser instead of ting for images, for performance reasons
splash screen + footer text
only search on søg-knap +(+on-enter-key, but not on blur)
Limit related to objects that have cover-links

Productivity: Normal 19

Tools: ClojureScript, HTML5, ElasticSearch

Starting point:

Takeways:

Studied how to implement efficient search in eigenspace
- kNN scales well on GPUs, multi-distance calculation can also be implemented as matrix multiplication
- Optimised BLAS/LAPACK seems like good option for performance, – recent versions also have GPU-implementations
- C++/(CL)JS implementation seems like a viable approach: Armadillo for linear algebra/search, node-gyp for glue, and webservice in node.js
Usability testing is very useful, looking forward for more next sprint
iOS-safari is the new MSIE
