This RAM bundle lets you skip the insane prices, but it won't last long
15+ min ago (546+ words) This deal surely isn't going to stick around for very long. DDR5 RAM has recently become unaffordable due to its manufacturers turning attention to the AI buildout. Whereas you used to be able to spend anywhere between $100 and $200 for a boss kit of memory, prices have spiked well into the hundreds. While the new normal seems to be ridiculous RAM prices, there are still some hidden gems that will allow you to get a new kit for the price it should be. The best deal right now is on this MSI B650 Gaming Plus WiFi motherboard and T-Force Delta 16GB DDR5 RAM bundle. Rather than the usual price of $319.98, you can get the mobo and RAM for $189.99 at Newegg.

Sega's CEO thought 'Jensen was a young man that liked' which helped save the company
27+ min ago (705+ words) It's easy to be whimsical about nearly ruining the company when it's now worth trillions. This prompted Jensen to start going over Nvidia's beginning, when it was a tiny group of engineers in 1993: "We were trying to create this new computing approach. The question is, what's the killer app? We wanted to create a new type of computing architecture, a new type of computer that can solve problems that normal computers can't solve." A noble goal, one might say. However, Huang hits the issue with this idea right on the head. "Well, the applications that existed in the industry in 1993 are applications that normal computers can solve, because if the normal computers can't solve them, why would the application exist? "And so we had a mission statement for a company that has no chance of success, but I didn't know…...

Jony Ive's OpenAI Device Barred From Using 'io' Name
37+ min ago (545+ words) A U.S. appeals court has upheld a temporary restraining order that prevents OpenAI and Jony Ive's new hardware venture from using the name "io" for products similar to those planned by AI audio startup iyO, Bloomberg Law reports. iyO sued OpenAI earlier this year after the latter announced its partnership with Ive's new firm, arguing that OpenAI's planned "io" branding was too close to its own name and related to similar AI-driven hardware. Court filings later showed that Ive and Sam Altman chose the name io in mid-2023, and that iyO CEO Jason Rugolo had approached Altman in early 2025 seeking funding for a project about "the future of human-computer interface." Altman declined, saying he was already working on "something competitive." OpenAI countered that io's first product would not be a wearable device, and that Rugolo had voluntarily disclosed details about iyO while…...
