"secure login" plugin seems to have stopped working despite a recent update I believe secure login stopped working on several popular sites due to changes in those sites' webforms. A while ago I applied a patch mentioned in the addons.moz

The videos at http://videolectures.net/ often pick out a momentary dramatic gesture for the thumbnail image. Out of context, they sometimes seem pretty extreme. I pulled out a selection here: http://homepages.inf.ed.ac.uk/imurray2/tmp/vl

The author, Brian Hayes, has an excellent blog at http://bit-player.org/ which is well worth following. Lots of posts about simple curiosities followed up much further than most people bother, and beautifully illustrated. The post pointin

Aside: I find it ridiculous that I can't read a blog post, a little bit of text and an image, without enabling javascript on two domains. I know that a bunch of you will think only masochists use NoScript, but the page is slow to appear and

Summary: The fit method of the distributions in SciPy does maximum likelihood fitting of parameters to data. This blog post gives a couple of nice quick examples. To see what else is available, one would go here: http://docs.scipy.org/do

I'd wondered why hitting 'O' after hitting escape led to such a nasty delay when running vim in a terminal. Now I know. For those that still want arrow keys in insert mode (sacrilege! ... but I do), this is probably the .vimrc option you wa

Interesting, but the linked device doesn't seem to desalinate water. It claims to filter out disease-causing organisms.

Warning: slight pedantry ahead. Specifically what this article is noticing is the law of large numbers [1], that sums or averages are "close" to their mean. The central limit theorem says that sums converge in distribution towards being

I'd like to see a study on this issue rather than an uninformative rant. I recently made my homepage text dark grey on just off-white. It's hard to tell quickly what I really prefer though. Conscious preference doesn't necessarily correspon

It regularly takes more than one email when I try that strategy. People don't always reply quickly. I either can't keep all the times that I offered open, or end up offering people very restrictive time ranges that they can't do.

Indeed. This type of study, while really popular in the press, is often horribly confounded and hard to control for. I think the hacker news audience mostly knows to be skeptical, so I don't know why it was submitted. I'll use this post as

What can you do with 640x360? — better than VHS quality. Sure I'd prefer HD, but that resolution was good enough to enjoy films in my childhood, so seems a feasible start for this technology now.

I take some of it back. Getting the latest version of wkhtmltopdf and telling it to wait (probably longer than necessary) to process javascript, works pretty well. wkhtmltopdf --javascript-delay 10000 --no-stop-slow-scripts 'http://

One should often consider applying tweaks to a final system. If there's an obvious place to introduce a free parameter, it seems silly not to do so and cross-validate the parameter against application performance. Things get out of hand if
