    - by Technical Bard
    Is there a way (ideally easy) to make headings and sections autonumber in HTML/CSS? Perhaps a JS library? Or is this something that is hard to do in HTML? I'm looking at an application for a corporate wiki but we want to be able to use heading numbers like we always have in word processors.

  • R: getting "inside" environments

    - by Mike Dewar
    Given an environment object e: > e <environment: 0x10f0a6e98> > class(e) [1] "environment" How do you access the variables inside the environment? Just in case you're curious, I have found myself with this environment object. I didn't make it, a package in Bioconductor made it. You can make it, too, using these commands: library('GEOquery') eset <- getGEO("GSE4142")[[1]] e <- assayData(eset)

  • Several ifstream vs. ifstream + constant seeking

    - by SpyBot
    I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?
