The clean energy solution has attracted about $2.8bn (£2.5bn) in global investment over the past year, compared with $1.9bn (£1.6bn) over the past decade.
There was also a breakthrough in late 2021 when researchers at the Joint European Torus (JET) facility in Oxford released a record-breaking 59 megajoules of fusion – almost tripling the previous 21.7-megajoule record from 1997.
That means, every time GNU tar wants to create a hard link, it first has to walk the entire linked list of delayed links and see if the target is a delayed link. The new link must also be delayed if the target is a delayed link.
Your time complexity alarm bells should be starting to ring now. For every hard link, we walk the list of all delayed links. But it gets worse; for reasons I don't quite understand yet, tar will go through the entire list of delayed links again if it finds out that it can create the connection immediately. So, all "normal" hard links must go through the entire linked list of delayed links twice.
