A category theory writeup describes how to construct a Yoneda-style embedding within double categories, a setting where presheaves cannot be directly expressed because objects are treated as abstract 0-cells rather than sets. The author sketches how to define a presheaf object and a Yoneda vertical arrow using universal constructions like horizontal arrows and left Kan extensions instead of direct references to sets or presheaves. A follow-up post is promised that will implement these ideas as working code in Haskell.
A longtime search marketer who began in the field in 1998 has published guidance urging entrepreneurs to rethink growth strategy around AI-driven search and creator collaborations. The advice centers on mapping customer questions before choosing marketing channels, then using that map to guide content, creator briefs and measurement of AI-search visibility. It also stresses partnering with creators who hold genuine audience trust rather than simply the largest followings.
Major AI companies are shifting focus from simple chatbots to more advanced AI agents that can independently handle multi-step tasks like booking travel, managing calendars, drafting emails and analyzing data. The article argues entrepreneurs should consider using these agents as quasi-co-founders to help scale operations without hiring additional staff.
MSI (Message Signaled Interrupts) lets a device like a GPU notify the CPU of an interrupt by writing to a memory address rather than fighting for space on a shared physical hardware line. Windows 10 and 11 default to MSI-X, an expanded version introduced with PCI 3.0 in 2010, whenever a device supports it. This approach labels each interrupt with its source, avoiding the collisions that can occur on crowded shared IRQ lines.
TechCrunch is giving startups until September 18 at 11:59 p.m. PT to reserve an exhibit table for Disrupt 2026, set for October 13-15 at Moscone West in San Francisco. The event expects over 10,000 founders, investors and operators, with exhibitors getting a branded table, ten team passes, lead-generation tools, press list access and Silver Tier sponsor status.
A developer documented practical issues encountered while porting large system prompts from Anthropic's Claude Opus to a self-hosted Ollama setup, citing the move as a response to growing distrust of frontier AI providers. The post argues that inference session data itself—not just user-submitted content—may hold competitive value, and cites the recent controversy over OpenAI's handling of a Navier-Stokes proof as evidence that providers may train on user activity without adequate transparency.
Máuhan M Zonoozy, who previously led innovation at Spotify and founded remix startup Bubbl before its acquisition by Cricket Media, has launched A Vinyl Bar in Shibuya, a startup building small apps for playing with sound and vocals. The company secured $5.5 million in pre-seed funding from investors including Mantis VC, SV Angel, Boxgroup, and former Spotify advertising executive Dawn Ostroff, who is advising the venture. Rather than one product, the startup releases experimental apps as 'singles,' such as a Chrome extension called Speed Surfer that alters browser audio and a stem-mixing tool called Stacks.
A Vinyl Bar in Shibuya, a startup founded by former Spotify innovation head Máuhan M Zonoozy, has closed a $5.5 million pre-seed round from investors including Mantis VC, SV Angel, Boxgroup, and Dawn Ostroff. The company builds a series of small apps and web tools, like Speed Surfer and Stacks, that let users manipulate and remix sound and vocals rather than generate music via AI prompts.
Senator Bernie Sanders has introduced the 'Ban Artificial Superintelligence Act,' legislation that would halt development of superintelligent AI until a federal regulator sets safety rules. Under the proposal, developers who defy these rules could face up to 20 years in prison, penalties comparable to existing laws on unlawful weapons development. Sanders says even AI executives like Dario Amodei, Sam Altman and Elon Musk now admit the industry must slow down, but argues their proposed measures don't go far enough.
A roundup of LinkedIn, WEF, Stanford AI Index, PwC, Lightcast, Indeed, Bain and Levels.fyi data shows AI Engineer as the most-hired AI role in 2026, with Research Scientist at frontier labs seen as the most prestigious. AI-related job postings and wage premiums have surged sharply, while prompt engineering is fading as a title and entry-level hiring has become tougher.
A Reddit user on r/pcmasterrace posted photos of two abandoned crypto mining rigs found in a basement, containing a dozen Zotac RTX 3070 graphics cards along with DDR4 memory, SSDs, power supplies and MSI Z390 motherboards. The rigs had been used for Ethereum mining during the pandemic and sat unused after home mining stopped being profitable, with the owner giving them away once asked.
Apple's iPhone 18 Pro and Pro Max pre-orders have slipped from launch-day delivery to estimates spanning late September into October, just days after orders opened.
