Fancy HTML5 Slides with knitr and pandoc | Yihui Xie
"Karthik Ram gave an Introduction to R a couple of weeks ago, and I strongly recommend you to take a look at his cool HTML5 slides. I started trying HTML5 slides last year, and now it is difficult for me to go back to beamer, which I have used for a few years for my presenations. It is horrible to see beamer slides everywhere at academic conferences (especially the classic blue themes)."

The TeX Catalogue OnLine, Entry for flowfram, Ctan Edition
"The flowfram package enables you to create frames in a document such that the contents of the document environment flow from one frame to the next in the order in which they were defined. This is useful for creating posters or magazines, indeed any form of document that does not conform to the standard one or two column layout."

"Jekyll at its core is a text transformation engine. The concept behind the system is this: you give it text written in your favorite markup language, be that Markdown, Textile, or just plain HTML, and it churns that through a layout or series of layout files. Throughout that process you can tweak how you want the site URLs to look, what data gets displayed on the layout and more. This is all done through strictly editing files, and the web interface is the final product."

"Grit gives you object oriented read/write access to Git repositories via Ruby. The main goals are stability and performance. To this end, some of the interactions with Git repositories are done by shelling out to the system's git command, and other interactions are done with pure Ruby reimplementations of core Git functionality. This choice, however, is transparent to end users, and you need not know which method is being used."

CASS
"In the social sciences, it is useful to understand the relative similarities of concepts that are embedded in a particular text (from a particular group or a particular person). For example, in trying to estimate conservative bias in FoxNews, one might estimate its tendency to associate conservative concepts (conservative, republican) and good concepts (good, positive, etc.), compared to conservative and bad concepts. The output would indicate conservative favoritism. This comparison could be further refined by taking into account important "baseline" information about the valences associated with liberal, namely liberal and good in comparison to liberal and bad.…"

[1006.0764] General Purpose Convolution Algorithm in S4-Classes by means of FFT
"Object orientation provides a flexible framework for the implementation of the convolution of arbitrary distributions of real-valued random variables.
We discuss an algorithm which is based on the Discrete Fourier Transformation and its fast computability via the Fast Fourier Transformation. It directly applies to lattice-supported distributions. In the case of continuous distributions an additional discretization to a linear lattice is necessary and the resulting lattice-supported distributions are suitably smoothed after convolution."

"The most recent version of Protovis, the open-source visualization library that uses JavaScript and SVG, was just released not too long ago - this time with more layout and examples. This is especially helpful since Protovis was "designed to be learned by example." Among the new stuff is the ever popular streamgraphs, along with the force-directed layout. With only 10 to 20 lines of code, you'll have your viz, so lots of bang for the buck."

Computation of the Hypervolume Indicator
"The performance assessment of algorithms for multiobjective optimization problems is far from being a trivial issue. Recent results indicate that unary performance measures, i.e. performance measures which assign a single value to each non-dominated point set, are inherently limited in their inferential power. Despite these limitations, the hypervolume indicator (also known as Lebesgue measure or S metric) is still considered to possess some reasonable properties, having also been proposed as a guidance criterion for accepting solutions in Multiobjective Evolutionary Algorithms. Therefore, the computational time taken for computing the hypervolume indicator is a crucial factor for the performance of such algorithms.…"

BoolNet--an R package for generation, reconstructi... [Bioinformatics. 2010] - PubMed result
"As the study of information processing in living cells moves from individual pathways to complex regulatory networks, mathematical models and simulation become indispensable tools for analyzing the complex behavior of such networks and can provide deep insights into the functioning of cells. The dynamics of gene expression, for example, can be modeled with Boolean networks (BNs). These are mathematical models of low complexity, but have the advantage of being able to capture essential properties of gene-regulatory networks. However, current implementations of BNs only focus on different sub-aspects of this model and do not allow for a seamless integration into existing preprocessing pipelines. RESULTS: BoolNet efficiently integrates methods for synchronous, asynchronous and probabilistic BNs. This includes reconstructing networks from time series, generating random networks, robustness analysis via perturbation, Markov chain simulations [&c]"

Streamgraph code ported to JavaScript
"Lee Byron open-sourced his streamgraph code in Processing about a month ago. Jason Sundram has taken that and ported it to JavaScript, using Processing.js.
The algorithms are the same as that in the original, but of course the natural benefit is that people don't need Java to run it their browsers. Jason has also added a few features including dynamic sizing, more straightforward settings, and some interaction with zoom and hover control. Really nice work."

DEoptim: An R Package for Global Optimization by Differential Evolution - Munich RePEc Personal Archive
"This article describes the R package DEoptim which implements the differential evolution algorithm for the global optimization of a real-valued function of a real-valued parameter vector. The implementation of differential evolution in DEoptim interfaces with C code for efficiency. The utility of the package is illustrated via case studies in fitting a Parratt model for X-ray reflectometry data and a Markov-Switching Generalized AutoRegressive Conditional Heteroskedasticity (MSGARCH) model for the returns of the Swiss Market Index."

apotonick's active_helper at master - GitHub
"Helpers suck. They’ve always sucked, and they will suck on if we keep them in modules.

ActiveHelper is an attempt to pack helpers into classes. This brings us a few benefits

inheritance helpers can be derived other helpers
delegation helpers are no longer mixed into a target- the targets use the helper, where the new
methods are delegated to the helper instances
proper encapsulation helpers don’t rely blindly on instance variables – a helper defines its needs, the target has to provide readers
interfaces a helper clearly provides methods and might use additional helpers
Note that ActiveHelper is a generic helper framework. Not coupled to anything like Rails or Merb. Not providing any concrete helpers. Feel free to use clean helpers in any framework (including Rails and friends)!"

Couchio - What’s new in Apache CouchDB 0.11 — Part Two: Views; JOINs Redux, Raw Collation for Speed
"Since then, though, CouchDB gained a few new features to tackle the same problem: fetch related data. These aren’t new in 0.11, but they did get refined, so it makes sense to revisit them here. Since 0.10, you could query a view with the query parameter include_docs=true. When specified, CouchDB would fetch, for each row in the view result, the corresponding document from the database. This allows users to make a trade-off between smaller view indexes (and hence shorter view index times) and slower view index (for each row, CouchDB makes a single request to the database)."

Patch Engineering - RakeServer is a client-server Rake architecture for fast task invocation
"Enter RakeServer, a tool Cedric and I hacked up this week. The idea here is to run Rake tasks using a client-server architecture, with a long-running server that responds to requests from clients to invoke tasks. The crucial feature of RakeServer is that it can also invoke tasks greedily when the server first starts — in particular the :environment task, which loads the Rails environment. That way, when the client invokes Rails-dependent tasks, the server is able to respond immediately without waiting all that time for the environment to load."

It’s not exactly a key value store, it’s definitely not a relational or document-oriented database. The biggest selling point of Redis is that usually as programmers we have to bend our data into a table or document to save it, but with Redis we can persist data as we conceptually visualize it.

Raphaël—JavaScript Library
"Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.
Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.
Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
For more examples take a look at charting plugin: gRaphaël"

Introducing Resque - GitHub
"It boils down to this: GitHub is a warzone. We are constantly overloaded and rely very, very heavily on our queue. If it's backed up, we need to know why. We need to know if we can fix it. We need workers to not get stuck and we need to know when they are stuck.

We need to see what the queue is doing. We need to see what jobs have failed. We need stats: how long are workers living, how many jobs are they processing, how many jobs have been processed total, how many errors have there been, are errors being repeated, did a deploy introduce a new one?

We need a background job system as serious as our web framework. I highly recommend DelayedJob to anyone whose site is not 50% background work.

But GitHub is 50% background work."

RubyWithRlang - SciRuby
"I've been playing with R and SWIG, and I think I'm almost to the point where I can call R from Ruby using a SWIG-wrapped R shared library. It took me most of a weekend to figure out the header files, but I got the simple subset of R (Rmath.so) talking to "irb" yesterday. The compilation part of the interface to the full "libR.so" appears to be working, but I (or some volunteer) needs to translate the tests that come with the R distribution from C to Ruby to check this out."

R on Rails with RSRuby
"To sum up, I use R with Rails successfully and very happily, but under controlled circumstances and not in a public-facing or uptime-crucial situation. I don’t have data on speed or memory usage, other than to say that I regularly run reports with dozens or even hundreds of different images and graphics rendering is not the most time consuming part of the task. What matters most to me is that I can easily prototype in R, and my library of graph types can be used in any environment that supports R. I am not locking myself in to a Rails-only or Ruby-only package. Also, although I haven’t even touched on it here, my Rails and Ruby applications have access to the rest of R’s extensive statistical and mathematical functionality and a huge package library."
