• How can I get the followers of a user on twitter, then get posts from those followers over a period

  - by Ronan

  I've been assigned a research project to enhance social networking based adaptive e-learning and to do so I need to be able to extract several (hundreds, maybe thousands) of status updates or tweets in order to perform factor analysis on key words. Apparently this can be done with javascript but I have never used javascript before so I'm a bit…

• C vs. C++ for performance in memory allocation

  - by Andrei

  Hi, I am planning to participate in development of a code written in C language for Monte Carlo analysis of complex problems. This codes allocates huge data arrays in memory to speed up its performance, therefore the author of the code has chosen C instead of C++ claiming that one can make faster and more reliable (concerning memory leaks) code…

• R Package for Bayesian Belief Networks

  - by user187395

  Is anyone aware of an R package for Bayesian Belief Networks (BBN) that can handle latent (hidden) nodes? I am referring to process learning the structure and the parameters of the model. Based on the documentation, the "bnlearn" package does not provide for such capability. In addition, is anyone aware of R packages that allow for making…

• Running OpenMPI on Windows XP

  - by iamweird

  Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code =…

• Real-time spectrum analyzer with API

  - by bobobobo

  I'm looking for a C or C++ API that will give me real-time spectrum analysis of a waveform on Windows. I'm not entirely sure how large a sample window it should need to determine frequency content, but the smaller the better. For example, if it can work with a 0.5 second long sample and determine frequency content to the Hz, that…

• Discussion Question: Why has Visual Programming Languages never taken off?

  - by anon

  Note: marked as community wiki. Is there a good analysis of why visual programming languages still haven't taken off? We're still coding these days 'linearly' in a 80x25 text window; while the concepts we represent (data structures, algorithms) seem like they can be more intuitively represented visually.

• I want to count the number of occurences of each character in a string

  - by roe

  Ignore spaces, punctuation and anything else that is not a letter. Ignore the case of the incoming letters (so e.g. 'A' and 'a' should be counted together). The results of analysing this string should be added to any analysis performed by previous calls to this method.

• What programming languages are good for statistics?

  - by Jason Baker

  I'm doing a bit more statistical analysis on some things lately, and I'm curious if there are any programming languages that are particularly good for this purpose. I know about R, but I'd kind of prefer something a bit more general-purpose (or is R pretty general-purpose?). What suggestions do you guys have? Are there any…

  I am using the platform Ushahidi Web-2.7.3 , see: http://ti5.net.br/provedorlegal.com.br, and when I zoom in beyond a certain level, the clustered markers disappear from the map.

  I want to crawl a website and store the content on my computer for later analysis. However my OS file system has a limit on the number of sub directories, meaning storing the original folder structure is not going to work. Suggestions? Map the URL to some filename so can store flatly? Or just shove it…

• How to remove "Standard Error" column from xtable() output of an lm on R/RSweave/LaTeX

  - by Lucas Spangher

  I'm currently doing some data analysis on population data, so reporting the standard errors in the tables of parameter coefficients just doesn't really make statistical sense. I've done a fair bit of searching and can't find any way to customize the xtable output to remove it. Can anyone point me in…

• Why doesn't web browsers have built in validators?

  - by August Karlstrom

  As far as I know there is no web browser with built in validators for HTML, CSS and Javascript. Developing web pages without validation is like using a compiler that doesn't do syntax analysis. Even Firefox with its excellent plugins aimed at developers like Firebug lacks plugins for CSS and…

  Long and short of the story is, whilst reading John Resig's blog (specifically http://ejohn.org/blog/javascript-trie-performance-analysis/) I came across a line which makes absolutely no sense to me whatsoever. Essentially it boils down to object = object[key] = something; (this can be…
