density plot on a log scale
I'm working with a large dataset - large enough that when I do a scatter plot the points all blur together, so I want to plot their density by color - a heat map or something like that. I've used smoothScatter for tasks like this, but the problem is that my current dataset really only looks good on a log-log scale. When I do the following command smoothScatter( data,

[llvm-mc] FreeBSD kernel module performance impact when upgrading clang
Hi, I'm in the process of migrating from clang5 to clang10. Unfortunately clang10 introduced a negative performance impact. The cause is an increase of PLT entries from this patch (first released in clang7): https://bugs.llvm.org/show_bug.cgi?id=36370 https://reviews.llvm.org/D43383 If I revert that clang patch locally, the additional PLT entries and the performance impact disappear. This

Windows XP and MP3
if ya' haven't seen it already, check out: http://www.canoe.ca/MoneyWSJ/wsj2-dow.html ad, sad, sad. on many fronts. I don't begin to understand how this might work; I suppose the MP3 degradation only applies to MS encoding software... *shrug* this may, however, provide a good leveraging point for Vorbis. have fun dongoodman

Macbook for Rails Development
Hi All, I''ve finally got fed up of struggling with Windows and am on the verge of splashing out on a Macbook for Ruby/Rails development. I''ve seen DHH''s post about it on loudthinking but I wondered if anyone else has any more wisdom... Is it worth it over a powerbook? Any tips on good OSX apps for Rails dev (textmate, i know already)? Anything not working well on

cenboxplot(): Reporting Limit Twice Correct Concentration
I've gone over the data and do not see my error; the dput() output of the data frame and the pdf output of cenboxplot() are attached. The command used: cenboxplot(sb.t$quant, sb.t$ceneq1, range=1.5, main='Total Recoverable Antimony', xlab='Pre-Mining Era', ylab='Concentration (log mg/L)') (on a single line in emacs). The RL on the plot is drawn at 0.01 rather
