It simplifies tax planning and complicates "tax planning". What's not to like?
EU regulators have renewed a push to create a common base for calculating taxable corporate profits with draft legislation that threatens to isolate Ireland politically as the UK prepares to quit the bloc.

might change everyone into penguins
The Hitchhiker's Guide to the Galaxy
"Arthur looked up. "Ford!" he said, "there's an infinite number of monkeys outside who want to talk to us about this script for Hamlet they've worked out."
"Ford," he said, "you're turning into a penguin. Stop it."
"But that's not the point!" raged Ford "The point is that I am now a perfectly safe penguin, and my colleague here is rapidly running out of limbs!""

The ExoMars project probably shouldn't have named their Mars lander after a giant crater.

Yes, now it gives rise to awkward ambiguity:
"wait, which schiaparelli crater are we talking about?"

In an episode of political violence, someone has firebombed a Republican office in the US and daubed "Nazi Republicans leave town or else" on the wall.

It isn't irony. It's just ignorance. I wonder who did it?

There is something Breitbarty about this incident alright....

If anyone other than +John Baez​ told me there was such a thing as triamond, I would be sure it was trolling without checking.

The structure of a diamond crystal is fascinating.  But there’s an equally fascinating form of carbon, called the triamond, that’s theoretically possible but never yet seen in nature.

In the triamond, each carbon atom is bonded to three others at 120° angles, with one double bond and two single bonds. Its bonds lie in a plane, so we get a plane for each atom.

But here’s the tricky part: for any two neighboring atoms, these planes are different. In fact, if we draw the bond planes for all the atoms in the triamond, they come in four kinds, parallel to the faces of a regular tetrahedron!

If we discount the difference between single and double bonds, the triamond is highly symmetrical. There’s a symmetry carrying any atom and any of its bonds to any other atom and any of its bonds. However, the triamond has an inherent handedness, or chirality. It comes in two mirror-image forms.

Some chemists have argued that the triamond should be metastable at room temperature and pressure: that is, it should last for a while but eventually turn to graphite. Diamonds are also considered metastable, though I’ve never seen anyone pull an old diamond ring from their jewelry cabinet and discover to their shock that it’s turned to graphite. The big difference is that diamonds are formed naturally under high pressure — while triamonds, it seems, are not.

It's the mathematics behind the triamond that really interests me.  It's a topological crystal that can be constructed starting from the complete graph on four vertices.  For the details of how this works, see my Visual Insight blog article:

It's rough to read it all in one go.
This is the most thorough and detailed analysis of the demagogue that is Trump I have read to date. I cannot imagine how anyone could read this, or know about even half of it, and still consider supporting this trashy danger to the world.
Herewith, we fervently pray, is the political obituary of Donald Trump and all that he stands for.

At I/O 2016, one speaker from Google declared that if you don't care about accessibility, then you are a bad person who should not be writing apps. It was received with applause. Google should be embarrassed that they've let standards slip so far.
You all know how passionate I am about this issue. Google is not the only offender in this context, but it has become a major one. ALSO:
I thought my eyesight was beginning to go. It turns out, I’m suffering from design.

Professionally, I'm interested in distributed systems, formal methods, quantum computing, security and the process of engineering reliable software.
Personally, I'm interested in aviation, law, ethics, politics, mathematics, psychology, and new learning experiences of almost any kind.

My favourite word is mamihlapinatapai (each expecting the other to do something first). It narrowly edged out rawa-dawa (the sensation of suddenly realising you can do something reprehensible, and no one is there to witness it).

I wish I lived in Miami so I could make this place my regular gym! I visited from overseas because I'd heard good things about the trainer Lazaro, and he lived up to that reputation. He gave close attention and improved a lot of little things in my technique that my regular CrossFit trainers had overlooked. I came away from this with better fitness and knowledge.
