Nothing bad actually happened. No one was killed or injured.

So much safer than your gas and steel industies

Nuclear is currently the safest energy source (measure in deaths per KWh http://www.forbes.com/sites/ja... ). Even in the worst combination of things going wrong, the harm to people is small, while there are hundreds of fatal accidents in the fossil fuel industry each year (search for something like 'gas explosion' on google news).

Imagine if cars were held to the same standards as nuclear power plants. You'd need to get crash rates below 1 in 100 million user years. Make sure that even in the worst crash imaginable (e.g. car at max speed hitting a crowd of people) nobody (except maybe the driver) was exposed to a harmful level of force. All fuel would need to be transported in something that could survive being hit by a plane. All emissions would have to be captured and stored until they were safe. You could get road deaths down from the 1.2 million per year ( https://en.wikipedia.org/wiki/... ) (not including deaths from pollution) but I think cars would not be cheap.

Have a check which model you got. Atleast with the early RAM bump, the new models shipped before the annoucement, so some people ordered the old one, and received the new one.

he still worked there 2 weeks ago https://www.youtube.com/watch?...

They released all the docs for the GPU, drivers are on their way http://dri.freedesktop.org/wik... https://www.youtube.com/watch?...

Looks like the column limit is still an issue. https://bugs.documentfoundatio...
"The tl;dr is: "increasing the column limit will increase the the memory needed for every sheet extremelly" unless we "change the column container to a dynamic container," a change that "might take much more time" than a month."
On the other hand 4.2 made big changes to how data is held in spreadsheets https://wiki.documentfoundatio... so maybe there is some improvement for large sheets if you don't actually hit the the hard limit.

Maybe you could file a bug for the second one.

Thanks, that's interesting stuff.

You have to take steps to make progress. You can take something useful and make it more open (like librem) or you could start from scratch and make something very basic that is completely open.

You can take bigger strides towards openness and get something like Novena, but then you make other sacrifices (size, cost, performance).

I guess if you had infinite money you could make a high spec, completely opensource laptop.

For a bunch of software that some people use, life is just easier on Linux. Applications like Gimp, Libreoffice etc tend to work better. Last time I tried GIMP on mac os x you had to click everything twice, once to focus the window and again to actually click something (maybe fixed now). Sometimes there are up to date no Mac builds of a project because none of the developers use mac, and none of the users with macs know how to compile it. Installing things can be a big pain compared to having a good package manager.

Berkeley Earth study took look at the urban heat island effect, and found while its is a real effect, it is localised and not effecting the global averages.

And yet some people still cling on to shell scripts for their boot system.

"set -o nounset" at the top of your bash script. Then bash acts a bit more like a real programming language, and gives an error if a variable is not set. More tips (and by 'tip' i mean pretty much essential knowledge) at http://www.davidpashley.com/ar...

This is why you should have
set -o nounset
set -o errexit
at the top of every bash script. Also no one should be allowed to write a bash script unless they have read http://www.davidpashley.com/ar...

For some rough numbers, at 5V a raspberrypi A+ takes 500mA plus 250mA for the camera ( http://www.raspberrypi.org/hel... ). Maplin sell a 5V 10Ah portable battery pack (for charging phones and tablets) which weighs 330g ( http://www.maplin.co.uk/p/mapl... ). So off the shelf hardware gives you a 13 hour battery life.

I assume if energy efficency is your goal you could do a bit better.

I assume that meant the boat was undamaged, not the rocket.
