4 worth-attention items40 digest lines

Worth attention

An independent security researcher published a write-up describing a pre-authentication remote code execution vulnerability in Apple Screen Sharing (macOS remote desktop/VNC feature). If accurate, this is a serious risk for any Mac with Screen Sharing enabled — worth checking exposure and disabling the service or applying a patch if one exists.
A solo builder shares a concrete lesson from tracking SEO metrics: their Semrush Authority Score rose from 2 to 5 while the count of real follow backlinks stayed flat at 4, showing the summary metric moved without the underlying signal changing. A useful reminder to check underlying backlink data rather than trusting composite scores.
Independent technical blog post exploring a best-of-K sampling training approach for models, framed as an alternative to standard loss-minimization training. Interesting for ML practitioners but research-stage.
A terse post titled "wiff" from wezfurlong.org (the author of WezTerm). Content and purpose aren't clear from the title/URL alone — could be a new dev tool release worth a closer look, but unverified.
