With that prelude out of the way, let's begin. Inside of emacs you can call up a list of potential completions by using the keyboard shortcut M-. (that’s "hit the meta key along with period", where "meta" is the Alt key for me). This applies in a wide variety of scenarios, like when completing class names or variables. If we want to ask emacs to hand us a list of potential references, then the system we want to hook into is this completions system. (This is the only time I'll assume we know wh

Nintendo's Back in VR With a New Virtual Boy, Coming Next Year for Switch

I keep wondering when Nintendo will get back into VR -- I asked Shigeru Miyamoto about it earlier this year, in fact. Well, Nintendo's going back to VR, sort of: the Virtual Boy is back, baby. Retro games and a Virtual Boy accessory for the Switch and Switch 2 are coming Feb. 17 next year. The Virtual Boy was one of several things the company announced for Mario's 40th anniversary in a Direct livestream Friday, including new remasters of Super Mario Galaxy 1 and 2.

Small, affordable, efficient: A lot to like about the 2026 Nissan Leaf

Nissan provided flights from Austin to San Diego and then to Washington, DC, and accommodation so Ars could drive the Nissan Leaf. Ars does not accept paid editorial content. SAN DIEGO—The original Nissan Leaf was a car with a mission. Long before Elon Musk set his sights on Tesla selling vast numbers of electric vehicles to the masses, then-Nissan CEO Carlos Ghosn wanted Nissan to shift half a million Leafs a year in the early 2010s.

New pathway engineered into plants lets them suck up more CO₂

arstechnica.com Unknown 2025-10-10 03:09:00

Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we've been pumping into the atmosphere. It would be nice to think that we could reforest our way out of the mess we're creating, but recent studies have indicated there's simply not enough productive land for this to work out. One alternative might be to get plants to take up carbon dioxide more efficiently. Unfortunately, the enzyme that incorporates carbon dioxide into photosynthes

Even as Nintendo has endlessly mined its classic consoles for nostalgic re-releases in recent decades, the company has seemed to completely ignore the existence of the Virtual Boy—its abortive 1990s dip into the world of early virtual reality. That's finally set to change next February with Nintendo's first-ever official re-release of Virtual Boy games—at least for players who invest $100 in a required Virtual Boy-shaped Switch dock (or a cheaper cardboard holder) to make them work.
