The post contains a ton of fascinating graphs from the new Spotify music dataset.

We can't resist the sad tone of E-minor! E-minor dominates E-major, unlike most other keys.
Distribution by musical key. 9% in C-major. 2% in C-minor. 7% in D-major. 2% in D-minor. 3% in E-major. 4% in E-minor. 8% in G-major. 3% in G-major. Audio Features Correlation Heatmaps The "loudness" score correlates with the "score" score. BPM is normally distributed with a mean around 120, of course. Tracks by duration, in 10 second buckets. A distribution around a peak median of 3 minutes, with outlier peaks at exactly 2:00 and 4:00, taping off quickly but for a peak at the >10min catch all.

The suffix "site" is uncommon in my circles (then, and now).

Without it, the data suggests that "social media" won from the beginning, clear by 2009, with "social network" only rising later in 2010, and then disappearing as quickly as it came by 2012 […]

.@brooke Remember this "temporary" banner for en.wikipedia from 2009? Wikipedia got a native mobile redirect in 2011, and we removed this banner from en.wikipedia long before then.

When applying a thick border all around an element in more than one color, the corners meet in a 45-degree angle, forming a diamond of sorts. That is established and seems reasonable.

That's certainly one way to find out a package exploded.

Email from npmjs.com. Hi, krinkle! Thank you for enabling two-factor authentication on your account. On July 7, 2025, your account will be enrolled for mandatory 2FA as you are a maintainer of high impact package: exit-x. High impact packages are packages with more than 1 million weekly downloads or over 500 dependents. You will not be able to disable 2FA on your account as long as you are a maintainer of a high-impact package. NPMJS.com page for "exit-x" package. A graph with a mostly flat line shoots straight up. Every week prior to June 2nd: 20 thousand downloads a week. June 9th: 500 thousand downloads a week. June 16th: 1.2 million downloads a week.

Slide 1 of 22: * Nokia. Confidential. Dated 10th of January, 2007. * Apple has agreed with Cisco on using the iPhone name, details not known. Slide 2 of 22: * User interface has been a big strength for Nokia. Consumer research indicates this is in decline. Urgent action needed to prevent further erosion of this position. * Expect Apple to launch lower-price point models soon. Hit for market position will come if Apple makes "mini” version of iPhone. Slide 4 of 22: * iPhone is not a super feature pack. No 3G nor HSDPA. Only a 2MB camera. Apple changes specs frequently though, no room for complacency.

The button is 3 times larger than any input field, and clearly outgrew its layout position. The button pops out and even goes over top of nearby text and input fields.
