I couldn't resist and made a Win95Button widget for Flutter today. By far the hardest part was to find a decent "blocky" font.

Dlouho jsem do "Střípků ze Silicon Valley" nic nedal, tak nahazuji tadyhle fotky z dnešní procházky San Franciscem. Žádné téma to nemá, jenom jsem náhodně cvakal po cestě.

Všechno CC-0, kdybyste to chtěli použít. (Ale souhlas lidí na fotkách nemám, tak bacha.)

Some new research from an intern in our Zürich office shows an approach to tSNE that allows real-time interactive visualization of large, high-dimensional datasets by leveraging GPU capabilities through WebGL. Oh, and it's open source too! Check it out ↓

“Tajmar’s results are exactly what you’d expect for the systematic error explanation: with a properly shielded apparatus, with no additional electromagnetic fields induced by the wires, there is no observed thrust at any power. They conclude that these induced fields by the electrical wires, visibly present in the other setups, are the likely culprit for the observed, unexplained thrust:

‘Our results show that the magnetic interaction from not sufficiently shielded cables or thrusters are a major factor that needs to be taken into account for proper µN thrust measurements for these type of devices.’

To the best of our knowledge, then, rockets will still require propellant. The EmDrive isn’t a reactionless drive at all, and all the laws of physics should still work. In short, we fooled ourselves.”

For years, many tinkerers and inventors have been claiming that some sort of electromagnetic cavity, e.g., the EmDrive, can create a reactionless drive. That is, they claim they can change the momentum of a rocket without any sort of change-in-momentum of anything else, violating Newton’s action-reaction law. Needless to say, much like perpetual motion, physicists are largely skeptical. But until now, we hadn’t yet found why they were achieving the results that they did. However, a new source of error was just uncovered: magnetic fields originating from the cables that power the device. Properly set up the device, away from cables and loops of wires, as Martin Tajmar’s team did, and guess what: your ‘anomalous thrust’ disappears.

The EmDrive, billed as NASA’s impossible space engine, really was too good to be true.

Quantum Soccer, where the ball is a wave function. You score when the probability in the goal is over a set threshold.

Here's the talk I gave with +Matt Sullivan today at #io18.

Who will I meet at #io18 tomorrow? In the afternoon, I'll be hanging around the Flutter area near Stage 3. Come say hi!
