World's Roundest Objecthttp://www.youtube.com/watch?v=ZMByI4s-D-Y%3Fhd%3D1The world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram. A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK.But the problem with this definition has long been apparent. The IPK doesn't seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram's dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance.The Avogadro project aims to redefine Avogadro's constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverseAug 3, 2013 12:21 PM

Tools to monitor website performance?https://news.ycombinator.com/item?id=6068848Hi,I'm curious what the current state-of-art for website performance monitoring is?Most of the tools I've seen are either Pingdom-style applications, which simply tell you if a website if up or down, or they're like YSlow-style, which run a bunch of tests to see if you're following best practices.But is there something like say, Chrome's SpeedTracer that you could run as a service, and monitor your website's performance over time? Or before/after each commit?What would you guys recommend to track the performance of your own website over time, or gather deep-level metrics?Could you use something like PhantomJS to achieve this?Are there any existing open-source projects that already do this?Cheers , VictorJul 19, 2013 8:06 AM

Ask HN: Anyone else seeing Gmail's "Display density: Compact" not working?https://news.ycombinator.com/item?id=5383558TL;DR: Gmail theme "Orcas Island" is borked. Any others?(Maybe I should have tried harder to squeeze "theme Orcas Island" into the title...)--Yes, this is using HN as "Google customer support", but what other option do I have?In Gmail's web client, I use the theme "Orcas Island" for a more pleasant experience. (Not only do I like the pictures; it also changes the background from white to a less bright gray-blue.)Today, in that theme, "Display density: Compact" is no longer working. Whitespace galore.I noticed some other Gmail changes, e.g. the prompt to confirm mobile phone number (for security notifications). So, maybe the same push broke this aspect of theming?So far, I've only noticed this affecting the theme "Orcas Island". (But, I'm not going to check them all...)Googling has revealed nothing on this.Mar 15, 2013 11:09 PM
