I would say sighting a straight line is a common practice used by builders and joiners to determine if a piece of timber is straight or bowed. It can be used to test any length of timber, but long pieces in particular, and requires no tools just eyesight with a good depth of field enabling focusing along the whole length of timber to be checked.
In December 2009 the European Union obliged Microsoft to offer a choice of browsers to their European customers when they installed new versions of Windows. This browser choice was also delivered in updates to Windows and so the Browser Choice screen was born and has been with us ever since. See my featured image of Microsoft’s browser choice screen offering Google Chrome, Internet Explorer, Safari, Mozilla Firefox and the Opera browsers amongst others.
Browser Choice Ends
It turns out that this requirement by the EU had a time limit of five years which has now expired. Consequently Microsoft have quietly withdrawn the option to choose other browsers and returned to providing Internet Explorer alone. People can of course continue to use other browsers with Windows as they see fit but Internet Explorer is now what comes out of the box.
I’ve had a Nespresso Pixie since June 2012 and at the same time I acquired a Nespresso Aeroccino milk frother (Aeroccino 3 to be precise). These devices are very nice to have and work well even after 2½ years continual use. The coffee is very nice too.
However there is a slight problem with the Nespresso Aeroccino milk frother but it is not insurmountable. It’s very easy to burn milk on the bottom where the most intense heat is applied. You can see it burnt on in this picture where the whisk has been removed.
This article advises how to keep a Nespresso Aeroccino milk frother clean. There are pictures portraying the burnt milk problem and advice is given on how to avoid it.
Robot Controlled Chemical Evolution, “It’s life, Jim, but not as we know it.”
Glasgow scientists studying Robot Controlled Chemical Evolution have created a robotic system where chemicals can evolve. I read about this in Gizmag, but followed it up with a quick read from the horses mouth at Nature magazine. The featured image is a picture looking down at the heart of the researcher’s robot.
Although thousands of asteroids have been discovered and their orbits determined there are thought to be many undetected ones. This asteroid will cross Earth’s orbit of the Sun every three years and is called Asteroid 2014 UR116. It was recently discovered by a Russian professor at Moscow State University, Vladimir Lipunov. It is the size of a mountain (400m across) – much larger than the 164 feet (50m) across mentioned in my post about Asteroid Day.
Having read about Asteroid 2014 UR116 in The Telegraph I can’t determine how much of a threat it is. On the one hand NASA says this Near Earth Object (NEO) doesn’t pass near enough to earth to be a threat, but on the other NASA says it will be an impact threat for the next 150 years.
There is a movement by astronomers, scientists, astronauts, artists, business leaders, and others, concerned for the long term safety of our species, other species, and our planet, to establish Asteroid Day on the 30th June each year commencing in 2015.
