For $100 more than the NSpire CX CAS you could buy a netbook and fill it with cutting edge mathematical software such as Octave, Scilab, SAGE and so on
Yeah, sure you can get that netbook, and get the cutting edge software, but can you use it on the SAT. Nope - so its not all that useful for a learning tool anymore, is it.
You should use a type of calculator you plan on using for your long term educational career. My good old TI-85 got me through 6 years of school, and I still have it 10 years later.
8.1. Principles
Number resources are nontransferable and are not assignable to any other organization unless ARIN has expressly and in writing approved a request for transfer. ARIN is tasked with making prudent decisions on whether to approve the transfer of number resources
It should be understood that number resources are not 'sold' under ARIN administration. Rather, number resources are assigned to an organization for its exclusive use for the purpose stated in the request, provided the terms of the Registration Services Agreement continue to be met and the stated purpose for the number resources remains the same. Number resources are administered and assigned according to ARIN's published policies.
Number resources are issued, based on justified need, to organizations, not to individuals representing those organizations. Thus, if a company goes out of business, regardless of the reason, the point of contact (POC) listed for the number resource does not have the authority to sell, transfer, assign, or give the number resource to any other person or organization. The POC must notify ARIN if a business fails so the assigned number resources can be returned to the available pool of number resources if a transfer is not requested and justified.
That seems clear to me.
We should propose that as a rule.
If your country falls off of the Internet for longer than 24 hours, you forfeit all of the address space allocated to your country, and it goes back in to the unassigned pool. All service points will be instructed to drop peering agreements with your country.
If your country wishes to continue a presence on the Internet, you may re-apply for IPv6 address space
