この のセキュリティースコアが とほぼ同程度のスコアなの、実際のデータを見に行くと Vivaldi のトラッカーブロッカーとか広告ブロッカーとかが無効の状態での評価っぽいんだよな…

以前からある別の調査でも、何も設定していないデフォルトの状態を比較するという方針で Vivaldi のセキュリティー評価が低いまま、というのがあって(しかもそれが Brave の中のエンジニアが作っているサイトだったということもあって)それとおんなじような現象が起きている気がする。

実際のところ Vivaldi はデフォルトといっても最初の起動時のオンボーディングでそういうトラッカー・広告ブロックとかについてもユーザーに選ばせる画面が出てくるから、セキュリティー意識の高い人であればなにかしらブロック機能も有効化して使っている人は多いはずなんだけどな…

‘비동의 강간죄’가 ‘남성 차별 인식’ 조장?···“‘감정’ 때문에 현실 젠더폭력 방치하나” www.khan.co.kr/article/2025... "한국성폭력상담소는 국민통합위원회 컨퍼런스 내용에 대해 “성평등 정책이 남성 차별 인식을 조장하고, 그 결과 청년 남성이 보수·극우화될 수 있다는 잘못된 인과관계를 국민통합위원회는 아무런 비판 없이 제시했다”며 “성평등 정책이 극우의 결집을 불러왔다는 주장은 극우 세력의 자기 정당화 논리를 그대로 받아쓰는 일이며, 정책 실패의 책임을 외부로 전가하는 책임 회피에 불과하다”고 했다."

Visiting my sister and family for Christmas, and they have a shiny new 3D printer, so naturally we've been playing with it. Here's a hats-and-turtles jigsaw puzzle.

The puzzle was made by taking a hat tiling and its combinatorially identical turtle tiling, and making a puzzle piece from each pair of corresponding tiles, so that each piece (or at least each non-edge piece) has a hat-shaped face on one side and a turtle on the other.

Despite this, every piece is different. To make a hat and turtle tiling correspond as closely as possible you must scale the turtles down by an irrational factor √(4/5) to make a turtle have the same area as a hat, and rotate by an irrational angle tan⁻¹(1/√15) to keep the distance between each hat and its turtle bounded. As a result of these irrationals, no two pieces have the hat and turtle in quite the same position relative to each other. Also, the rotation makes corresponding edges skew to each other, so the sides of the puzzle pieces aren't flat planes – they all have a compound curve.

Some of the tiles are truncated by the circular frame, of course. When a piece of tile was just _too_ small, I made it part of the frame, which gives a starting point for placing other pieces. The four-colouring (suggested by my brother-in-law) also provides clues to the layout. I was quite scared that this puzzle would be too hard, and _might_ have gone a bit too far in the other direction making sure it was possible!

Inspired by a thread last year hachyderm.io/@simontatham/1133. Hat tip to Oskar van Deventer, who had a similar idea, and produced a puzzle with hats on one side and the degenerate chevron tile on the other (and without the four-colouring or frame protrusions).

A collection of 3D-printed puzzle pieces. Some appear to be hat-shaped, and some turtle-shaped (but in reality every piece is both, with a hat on one side and a turtle on the opposite side). Some pieces are partial, cut off by a curved edge. The pieces come in four colours: white, black, green and brown.

Two black semicircles with a few inner protrusions form a frame that the rest of the pieces are intended to fit into. One black piece, the same colour as the frame, is a hat in the opposite handedness from the othersThe puzzle mostly assembled, but shown in two halves. The rear half has the hats side uppermost, and the front half the turtles side. Each half is shown with the inner edge towards the viewer, so that you can see the slanted and slightly curved edges of the pieces.The fully assembled puzzle, shown on the hats side. The region within the circular frame is tiled perfectly with hats, with no two tiles of the same colour touching.The completed puzzle flipped over, so that the turtles tiling on the other side is visible.

You'd think after publishing 9 novels in 13 years, I'd have made my peace w/ the need to promote them.

I'm still conflicted re: anything that smacks of self-promo. I believe in my work. I'm proud of what I write & very much want to share it with readers.

But the work doesn't magically announce itself to the world.

So if you're looking for SF&F books that are earnest, honest, compelling & character focused, give them a try?

2 are free/pay what you will at Gumroad.
