New comment by jyunwai in "43 hours battery life: Dell XPS 14 2026 lasts almost 3x longer vs MacBook Air 15"

jyunwai — Thu, 02 Apr 2026 00:25:15 +0000

> "Moving on, the Dell XPS 14 (2026) endured for around 20 hours and 21 minutes when playing a 4K YouTube video. The MacBook Air 15 M5 lasted for 14 hours."

> "Finally, the Apple M5 showed its efficiency advantage under maximum load. The MacBook Air 15 M5 kept going for 4 hours and 10 minutes while gaming. The Dell XPS 14 could only hold out for 2.5 hours."

That about fits my personal experience. The dozens-of-hours-long battery life claims for laptops are based on streaming videos, but real-life battery life is always far shorter for me, as I usually use my laptop for more intensive tasks.

New comment by jyunwai in "The End of the Orbital Index"

jyunwai — Thu, 08 Jan 2026 15:23:17 +0000

It's too bad as I could not find any newsletter like it as a replacement. But I appreciate the sentiment that the space industry has grown enough that it's no longer so niche.

I'll also be missing the SAPIENS online magazine with its newsletter, which also shut down in December.

New comment by jyunwai in "Ghostty is now non-profit"

jyunwai — Thu, 04 Dec 2025 01:00:50 +0000

More context: 501(c)(3) orgs are non-profits that include charities, whereas 501(c)(6) orgs are non-profits with less strict requirements. Both are tax-exempt federally, but 501(c) orgs have higher financial transparency requirements and higher restrictions on political activity (which qualifies donations to 501(c)s as tax-deductible).

New comment by jyunwai in "How to Use Em Dashes (–), En Dashes (–), and Hyphens (-)"

jyunwai — Fri, 28 Mar 2025 04:04:50 +0000

Em and en dash usage is officially part of style guides such as The Chicago Manual of Style [1], so it's often a work requirement for many writers and editors to use them in writing. This is why these kinds of dashes are everywhere in newspaper and magazine articles.

Eventually, people learn to include them out of habit—especially as most people see them as aesthetically nicer than a simple hyphen (-).
