NSA-proof your e-mail in 2 hours You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. Today we kill your excuses. Now fair warning: it took me about two days to figure the stuff out you’re going to see in this blogpost, starting from knowing basically nothing about modern e-mail servers. So bookmark this blog post, block off a Saturday next month, and get it done. Edit Some people are complaining that the NSA is pulling all the e-mail over the wire anyway, so encrypting your own server is stupid. In the next two hours, we’re going to fix this. You’re going to host your own mail.It’s going to be encrypted on the server, locked-on-boot, SSH on reboots to unlockWhile we’re at it, let’s fix some things that annoy me about GMail:Better SPAM detection. I’m going to assume: Hang on just a minute though. Let’s get started!

Ministers want to remove obligations on local authorities to assess air quality in their areas, resulting in less monitoring. But environmental campaigners are accusing them of trying to hide one of the country's biggest public health problems. Government advisers have estimated that one type of pollutant – miniscule particles from diesel engines, fossil fuel power stations and other sources – is killing 29,000 people a year in the UK, and costing health services about £16bn. But European air pollution limits meant to protect health are being breached in urban areas across the country, with the highest levels in London. But now Defra has launched a six-week consultation, due to close on 30 August, proposing a radical overhaul of the local air quality management regime that has been in place since 1997.
Particulates This diagram shows types, and size distribution in micrometres, of atmospheric particulate matter This animation shows aerosol optical thickness of emitted and transported key tropospheric aerosols from 17 August 2006 to 10 April 2007, from a 10 km resolution GEOS-5 "nature run" using the GOCART model.[1][2] (click for more detail) * green: black and organic carbon * red/orange: dust * white: sulfates * blue: sea salt Movie map of distribution of aerosol particles, based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. * Green areas show aerosol plumes dominated by larger particles. * Red areas show aerosol plumes dominated by small particles. * Yellow areas show where large and small aerosol particles are mixing. * Gray shows where the sensor did not collect data. Atmospheric particulate matter – also known as particulate matter (PM) or particulates – is microscopic solid or liquid matter suspended in the Earth's atmosphere.
