> As to why the UK government doesn't pass a regulation that airport security is also responsible for detecting large amounts of cash, I have no idea.

Shouldn't law abiding citizens have the right to possess and carry cash?

Nobody says you can't, carrying whatever amount across the border is perfectly legal. What's illegal is trying to carry >10k without declaring it to the customs.

If you're a law abiding citizen, why wouldn't you declare it? If you don't, well congrats, you're no longer a law abiding citizen.

They have but it needs to be declared so as to avoid tax evasion and money laundering

Whether or not our citizens should have the right to do something seems rarely related to whether the UK government sticks its noses in our business to make sure we aren't.

You sound like the kind of person I'd actually want to start a business with. Maybe cofounder matching should be a HN feature instead of a tinder clone.

Any on cryptographic elections. Maybe this one - https://www.microsoft.com/en-us/research/publication/receipt...

Not a cryptographer. The extent of my expertise is that when I was in college I did a survey of ~15 papers on cryptographic elections. Take my suggestion with a grain of salt.

Very cool! One small point of pedantry:

> A tree with multiple inheritance (sometimes called tangled tree) cannot be represented by using a classic tree visualization. It is technically a directed acyclic graph (DAG) with one (or more) nodes identified as root.

What is the difference between a DAG and a tangled tree? Isn't any DAG a tangled tree? I don't see immediately why a new definition is required.

I'm not entirely familiar with tangled trees, but it seems like one of the larger differences is that a tangled tree isn't necessarily acrylic. For this example, someone could navigate away from one page, but potentially be linked back to it later down the adventure.

> A tree with multiple inheritance (sometimes called tangled tree)

By the author's definition, multiple inheritance prohibits cycles. DAGs can be modeled as tree with back edges to non-ancestors. So I'm pretty sure tangled tree = DAG.

> For this example, someone could navigate away from one page, but potentially be linked back to it later down the adventure.

Good point, maybe "tangled tree with back edges to ancestors" is the really correct model for what the author wants. The key point of the visualization is to highlight the deviation from a standard DAG or tree.

The author already says that:

> It is technically a directed acyclic graph (DAG)

But DAG's don't have 'roots', they just have nodes. The concept of roots makes it a tangled tree.
