As part of a periodic purge of unused online accounts, I deleted my account from a company ten months ago. Let’s call that company Contoso.

Bill Gates-backed AirLoom begins building its first power plant

Wind power has run into some headwinds, and not the kind that spin its turbines. Recently, President Trump has decided to wage war against the technology, an unwelcome bit of friction that coincides with rising costs in recent years. Onshore wind power went for $61 per megawatt-hour last year, according to Lazard, bucking a decade-long downward trend. “We have a lot of headwinds,” acknowledges Neal Rickner, CEO of wind startup AirLoom Energy.

That allows it to purify the air it puts out, removing things like dust and allergens from the air you breathe. Dyson claims it can catch particles as small as 0.3 microns wide.

Since Avengers: Endgame, the MCU has examined which heroes will step up now that most of the original characters have bowed out. In the case of Iron Man, this question has mostly been answered in Spider-Man, but fans of the armored Avenger’s comics know his actual successor comes in Riri “Ironheart” Williams, introduced in 2016 by Brian Michael Bendis and Mike Deodato, Jr. Marvel brought Riri into the cinematic fold with 2022’s Black Panther: Wakanda Forever, with the promise of her eventually

The economics behind "Basic Economy" – A masterclass in price discrimination

news.ycombinator.com Unknown 2026-03-03 05:55:53

Basic Economy fares are ultra-restricted airline tickets that offer a lower base price in exchange for fewer benefits than standard economy class. Introduced by major U.S. carriers in the 2010s, these fares have become a widespread strategy for market segmentation - a textbook example of price discrimination in practice. By design, Basic Economy compels travelers to self-select based on their willingness to pay and tolerate restrictions, thus allowing airlines to maximize revenue from different
