call/cc was introduced, as i understand it, as a means of formalising goto in this paper: Denotational semantics of goto: An exit formulation and its relation to continuations. Cliff B. Jones. http://www.springerlink.com/content/f340274565

section 8.7 deals with relational algebra. this is a really nice mathematical underpinning to SQL.

why would you want to be a programmer for more than 5 years if managers view the position with such disdain?

given the $100-125K figure, it seems like the message isn't "lower = better" but "frugal = better". perhaps a frugal CEO makes for an efficient company.

what about 3D or 3D with time in R? this is what python has: http://code.enthought.com/projects/mayavi/ i'm not really sure about far superior for 2D: http://matplotlib.sourceforge.net/users/screenshots.html vs. http://had.co.nz/ggplot

it's true that CRAN+Bioconductor have a lot of coverage of statistics. if you need to fit a particular kind of model and it's not using MCMC then perhaps it's the best you can do if someone has already written the code. we use sage ( http:/

i've used R for several large projects. it sucks in several ways for the projects i worked on: 1. it is extremely slow for numerics. slower than MATLAB. slower than python (with numpy). after talking to several stats people, it seems pretty

i don't understand why "intelligence"/"smart" is a good thing to optimise/aim for: 1. it's not a well defined quantity. 2. under any definition, it doesn't seem to be anything useful in itself. can some entity create an entity better at a t

i'm pretty sure everywhere you put "base", was "32" before. the only 29 in the code when i read it, was on the checksum. why did you pick this checksum? what are its coding properties?

as far as i can tell, the "10:10 code" is just a linear rescaling of the longitude and lattitude then encoding in base 32 (with a checksum for the last four bits). if the above is correct, why not explain it thus? if you do this, it becomes

it's more a problem with the APIs for talking to the vendor's DB. the easiest way to add user input to a DB query should be the right one. minimally, a DB query should not be trivially the same type as user input.

if f is the logistic function, then neural networks basically correspond to logistic regression. http://en.wikipedia.org/wiki/Logistic_regression which has been around since the 1940s... (multilayer neural networks correspond to hierarchi

the gamma distribution is often used (for example, in neuroscience for spiking rates for the refactory period) to capture the case where you do not wish to give support to zero plus some short period after zero. the exponential distribution

each driver decides whether or not to increase the distance to the next car. there are many such decisions that result in the total distance to the next car: i think it's a constant adjustment rather than just one decision. another view mig

it looks more like it's gamma distributed to me: you could imagine the generative process is something like a sum of exponentially distributed decisions times.
