Whenever someone asks:you don't need to read anymore, just point them to this page immediately. Virtualization for the win.

PNG reference implementation. Ahh, if feels good to have a dominating open source reference implementation.

Uranium-based, dropped on Hiroshima. The uranium was enriched at the Clinton Engineer Works.

A Python wrapper over a bunch of numeric and computer algebra system packages to try and fully replace MATLAB et. al.

For example, their

Quickstart tutorial at: www.sagemath.org/tour-quickstart.html From this we see that they are very opinionated, you don't need to import anything, everything has a pre-defined global name, which is convenient, e.g.:is the 3D vector space over the rationals. This also suggests that they are quite focused on computer algebra as opposed to numerical.

Sets both a Dirichlet boundary condition and a Neumann boundary condition for a single part of the boundary.

Can be used for hyperbolic partial differential equations.

We understand intuitively that this imposes stricter requirements on solutions, which makes it easier to guarantee uniqueness, but also harder to have existence. TODO intuitively why hyperbolic need this extra level of restriction.

In Ciro Santilli's view, the following three artists form a Holy Trinity of popular Brazilian music:

Elis Regina is not far though.

Ciro remembers quite clearly when he was riding the car with his parents when he pre teen, and he could not understand why they seemed so obsessed with The Trinity et al. Ciro in particular remembers listening to Video "Refazenda by Gilberto Gil (1975)". They had picked it up of course from the 70's and 80's when they were younger.

Young Ciro would also always confuse who was whom from the three of them.

Then Ciro got older, and he understood, they are mind blowing. You do have to look back in time a bit though, lots of lukewarm stuff on later periods. The military dictatorship in Brazil was good for music.

If something does a quantum jump, what causes it to decide doing so at a particular time and not another? It is expected that a continuous cause would have continuous effects.

This concern was raised immediately by Rutherford while reviewing the Bohr model in 1913 as mentioned in The Quantum Story by Jim Baggott (2011) page 32.

The more heavily a project relies on it, the more you start to regret it.

It is quite comical that two separate towns were founded one next to the other right in the middle of nowhere. And that both have so slightly weird names.
