I honestly thought the Liberal Democratic Party was part of the "Liberal Party", since what is referred to as the Liberal Party is actually a coalition of 4 (I think) different parties with names of a similar structure.

And they sure as heck aren't liberal in policy, either. In fact they are the more conservative of the two main parties.

Actually they already use GPUs - and there are companies making ASICs now. Dedicated Bitcoin mining boxes. The people who purchased GPUs specifically with mining in mind are apparently already annoyed, because the new computational power coming online means they are seeing less return, due to the increasing requirements as the number of mined bitcoins increases.

I'm not a fan of white noise, but at various times and moods I've found other noise types (pink and brown in particular) to be effective. I've used http://simplynoise.com/ in the past as the generator - combined with a set of good headphones, it will block out most sound.

Another alternative I use is orchestral music - specifically, no vocals. This makes it less attention grabbing. But I can't use it when I am trying to be creative/problem solving, for some reason.

Actually, Valve is mentioned in the article as one that people wanted investigated - but not as one that required a subpoena to provide information. This suggests that Valve voluntarily told them how their pricing works.

Which, as far as I know, is "We set what price the producer wants us to, or they refuse to sell on Steam at all."

You're right, it's not just CSG - although the system does contain CSG-esque boolean operations.

Our currently live product (Symvol) shows how our software does keep a tree - and we use point evaluation for producing output. MeshUp is going to be more targeted/simplified to use, so the tree possibly wont be shown/will be an advanced view.

It's definitely marketing hype, but that's the kind of thing marketing is about.

There's kind of two processes being described in the product. Mesh repair is working with polygons and adding/modifying the polygons to produce a better mesh. This is intended to make better meshes for the second part, which is mesh mixing. Mesh mixing is functional, so can be sampled at any resolution.

Without getting into too much detail:

No, it's boundary is just a side effect of the definition. We use zero value to be the boundary, but that's just a convenient convention.

NURBS and other parametric surfaces still have limitations. It's very difficult to define complex shapes with them, and the boolean operations often break, leaving you with gaps between patches or surfaces that have no matching other side. The staff and beta testers include people experienced with polygon and NURBS, and there are things people are used to not being able to do (or have to do certain ways) with NURBS that "just work" with this system.

Functional objects aren't new, by any means (they predate polygons in fact). We're using some new functions (rather then the boolean ones used in existing CSG modelers).

3D printing resolution IS limited by the polygons. If you try to put a mesh into any existing printing software that has individual polygons sized at the precision of the motors, the software does break (and the mesh file will be measured in gigabytes).

And yes, "resolution of nature" is a marketing phrase. Don't ask me, I just work here.

G-Code is closer to the role PostScript fills in 2d printing, but it's only loosely standardized, and every printer seems to need their own sub dialect of it. That's why there's still a common interchange format being used, with printer specific software/settings being used to produce the G-Code that actually goes to the printer.

We do support outputting to slice oriented formats (Bitmap and another that I've just gone completely blank on), but we don't use these internally. Instead, our software is using 3D functions. There is existing software that does this (CSG modellers) however we use both a different set of functions to those traditionally used, that have better properties for smooth objects (in our opinion).

Being mathematical, they are accurate to whatever numerical precision is used, so we can produce slices (our preferred format) or meshes at whatever resolution is wanted, as appropriate for the printer.

(The Fine Summary doesn't include that we already have an existing product based on the technology, but we want to make a more targeted version that doesn't require the customer to also have the Rhino 3D modelling software.)

The trouble is, everyone working with the new media is trying to bring the old workflow directly over. For example, the generic file format for 3D printing models is STL - a truly terrible file format that is a simple list of free floating triangles (no shared vertices or anything nice).

We (the people are Uformia) aren't really aiming for visual modelling. It's the printing we're aiming for. And we think just adding more and more complex methods of describing surfaces isn't enough, especially with the new printers coming out that combine materials.

The same issues as polygons - they break, leaving gaps when performing complex operations (or even not complex, if you don't do it just so).

It can be made to work, with a lot of effort and experience, but this is a new way that doesn't have those limitations. Not to say it doesn't have others, of course - mostly it's rather slow, compared to surface modelling.

Duplicity uses librsync to generate the changeset that rsync would use, then stores the change set. If you stored the change set to the USB drive, this could then be "restored" to the destination drive, perhaps? I don't know if there's any way to do this out of the box, or with a bit of scripting, or if this would need to be a whole new toolchain.
