At least in EU, private book/media rental is not legal without special licensing from copyright holders, while public libraries have exception for this.
Tool rental is a service that is commonly provided by private sector. I do not see a reason why this should be provided by a government. This seems like unfair competition to e.g. community hackerspaces.
50% property tax is just seizure without compensation, which is generally considered human rights violation.
If government wants 50% of shares, it can just buy it (or expropriate it with compensation) and use its ability to get cheap long-term loans to finance it.
> Second, many people think that the C runtime doesn't know the amount of memory allocated to an array, but this is actually false. It's just the C abstract model that for some reason chose to not expose this information.
There are some counterpoints:
1) Conceptually, allocated memory block and data structure / array in it are not related. You can allocate memory block and then subdivide it to multiple different structures / arrays. You can implement sub-allocators.
2) Heap allocator does not need to store exact length of allocated object. For example, it could have several fixed-length slab allocators for smaller objects, select matching one during malloc() and use address range to find slab during free().
3) Array can be also on the stack (VLA or alloca()).
4) Arrays can be also on memory allocated outside of C library allocator (e.g. mmap()).
These constraints, at least for electricity, are usually in end distribution networks, not in production. High-powered datacenter would get (and pay for) its own substation/transformer from higher-voltage network, thus avoiding the limitation.
The main point of ENUM was compatibility with open SIP, unfortunately that never really happened and most SIP operators do not accept incoming calls from public internet (and do not route outgoing calls based on ENUM).
IMHO soldering two wires together (or wires to connectors) is much harder and requires higher dexterity than through-hole soldering on PCB, which is really easy. PCB holds parts in place and directs solder where it belongs.
Even if the house prices stayed the same, it would make sense to keep the low interest debt and invest in other assets that have higher yield, like shares.
