A while ago I wrote a Google Toolbar button for redirecting the current page to the same page accessed through an EZproxy server. As I was missing this functionality in browsers without Google Toolbar (it’s still not available in Google Chrome), I realized that it’s a very simple thing to do with a bookmarklet. Here is the code:
javascript:window.location=location.protocol+'//'+location.hostname+'.ezproxy1.library.arizona.edu'+location.pathname+location.search+location.hash;
If there is a good thing about having a cold/flu it’s that you get around to do those little things you’ve been putting off for months or years (because you’re not up for much else) — like getting your blog in order. I’ve used Blogger some time ago, then installed WordPress, but never moved old posts… So here they come now.
As I was writing my compacton paper, I needed to format my references following the International Journal of Non-Linear Mechanics style. So I wrote a .bst (BibTeX bibliographic style) file that gives pretty much the desired output: ijnlm.bst.
This is an interesting article on caffeine and migraine. I thought the connection was obvious, I had no idea it is something still debated/not explicitly shown in studies.
use strict;
use XML::LibXML;
# data source
my $xml_filename = "xml/data.xml";
my $parser = XML::LibXML->new;
my $doc = $parser->parse_file($xml_filename);
my $xpath = "//word/entry[\@src=\"pr\"]/..";
my @words = $doc->findnodes($xpath);
foreach my $word (@words) {
print $word->findvalue("\@id");
print "\n";
}
Here is a Perl snippet that transforms an XML file with XSLT:
use strict; use XML::XSLT::Wrapper; my $xml_input_filename = "xml/data.xml"; my $xml_output_filename = "xml/out.xml"; my $xsl_filename = "xml/transform.xslt"; my $xslt = XML::XSLT::Wrapper->new( ProcessorList => [ 'libxslt', 'sablotron', 'xslt' ], ); my $result = $xslt->transform( OutFile => $xml_output_filename, xml => $xml_input_filename, xsl => $xsl_filename, ); $xslt->dispose();
As I signed up with Blogger a few years ago, and have never looked at alternatives, I decided to do so now, just to check whether I’m missing on something. Here’s what I found.
If you are using Google’s sitemap generator [code]]czoxNDpcInNpdGVtYXBfZ2VuLnB5XCI7e1smKiZdfQ==[[/code] to generate a sitemap of your Blogger blog , here are the configuration lines to add to the config.xml file:
Create a symmetric matrix in Mathematica
Here is a quick way to create a symmetric matrix in Mathematica. The code below creates a generic 6×6 matrix (line 1), then mirrors the above-diagonal elements to their below-diagonal counterparts (substitution in lines 3-5).
am = Array[Subscript[a,##] &, {6,6}]; am = am /. Flatten[Table[ Subscript[a,i,j] -> Subscript[a,j,i], {i,2,6}, {j,1,i-1}]]
