Puzzle 534: Fencing Match 46

It has recently come to my attention that two numbers which commonly appear in these puzzles have been the intellectual property of Microsoft for over a decade. I have created this puzzle without those numbers as a result. Remember, kids, infringing on patents is bad for you!

This is not a puzzle.

I don't normally consider myself an activist for things (I associate activism with annoying the crap out of people who disagree with you and making them hate you forever), but this is a rare and notable exception.

The United States Congress is discussing two bills called the Stop Online Piracy Act (SOPA) and the Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act (PROTECT IP). From my understanding of this bill, as presented by some guy in the United Kingdom(!), if either bill passes, Google could very well be forced to take down Blogger because of the mere potential for people to use it to infringe copyrights, thanks to some very vague definitions of what constitutes a rogue site. This will mark the death of Web 2.0, and more particularly, this will mark the death of my blog. (It will also mark the death of Thomas Snyder's blog and Palmer Mebane's blog, but nobody cares about those, right?) I really hope to learn more about these bills so I can be rational and not irrational, because if these bills are indeed as bad as I hear, then rational people will be better at getting the message out than irrational ones, but if you care about my blog's existence, please learn as much as you can about SOPA and PROTECT IP, act on the information, and encourage others to do the same.

I only discovered Nikoli and became the skilled logicsmith that I am today as a result of reading Zotmeister's blog, which wouldn't have existed without the innovations of Web 2.0. I cannot allow these bills to be passed if they would threaten this freedom of expression.

Rules -- Solomon's Keep

Solomon's Keep was invented by the Japanese puzzle company Nikoli (under the name Five Cells – that's a transliteration, not a translation, believe it or not).
1. Divide the grid along the grid lines into pentominoes (regions containing exactly five cells each).
2. A number in a cell represents how many edges of that cell are borders of pentominoes (including the perimeter of the grid).

Puzzle 529: Ellbound 1

This puzzle appears in "Penpa 2012 by Nikoli"; when a puzzle appears outside of Puzzle Communication Nikoli's experimental section, you know it's legit. Curiously, though, none of the 20 puzzles therein exhibit symmetry.

Rules -- Ellbound

Ellbound was invented by the Japanese puzzle company Nikoli (under the name Sashigane, which refers to a carpenter's square).
1. Divide the grid into L-shaped blocks, each consisting of an elbow, a horizontal arm extending from the elbow to another cell in the same row as the elbow, and a vertical arm extending from the elbow to another cell in the same column as the elbow.
2. A cell with a circle in it is the elbow of its corresponding block. If the circle has a number in it, that number represents how many cells are in that block.
3. A cell with an arrow in it is the tip of one of the arms of its corresponding block, and the arrow points to the elbow of that block.
