Vector databases (DBs), once specialist research instruments, have become widely used infrastructure in just a few years. They power today's semantic search, recommendation engines, anti-fraud measures and gen AI applications across industries. There are a deluge of options: PostgreSQL with pgvector, MySQL HeatWave, DuckDB VSS, SQLite VSS, Pinecone, Weaviate, Milvus and several others.The riches of choices sound like a boon to companies. But just beneath, a growing problem looms: Stack instability. New vector DBs appear each quarter, with disparate APIs, indexing schemes and performance trade-offs. Today's ideal choice may look dated or limiting tomorrow.To business AI teams, volatility translates into…

Illustration by Tag Hartman-Simkins / Futurism. Source: Getty Images As technical education goes, few American institutions can match the prestige and influence of MIT. Of course, not every graduate is destined for greatness, as two MIT alums made clear earlier this year when they got busted for allegedly pulling a lightning-fast crypto heist, making off with an estimated $25 million. The duo — two brothers named Anton and James Peraire-Bueno — were recently indicted in a federal court on charges of conspiracy, wire fraud, and money laundering in what prosecutors call a “first-of-its-kind” financial crime, according to Business Insider. In…

PowerA Fusion Pro for Xbox: One-minute reviewIt brings me no pleasure to find that the PowerA Fusion Pro Wireless Controller for Xbox is the most disappointing product I’ve tested in the brand’s catalog to date. PowerA is admittedly a brand I’ve had mixed feelings about in the past. Sometimes it provides real winners, like the PowerA Enhanced Wireless Controller, which I consider a solid alternative to the official Nintendo…

At a time when startup hustle culture is back, when “locked in” tech founders have even embraced the “996” way of working — 9 am to 9 pm, 6 days a week — there is something dystopian about using an AI app to generate fake vacation photos of yourself. And yet, here we are. Product designer Laurent Del Rey, who recently joined Meta’s Superintelligence Lab, launched a side project called Endless Summer, a photobooth app for iPhone that creates AI-generated vacation photos starring you in locations around the world. Here you are exploring a beach town, or overlooking a European…

Taking notes is something many of us do throughout the day. I know I can’t get through mine without setting reminders or jotting down a few things to jog my memory. It’s like I’m still in school and note-taking is my saving grace before the next test — except instead of studying, I’m just trying not to forget something I need to do. Whether I’m in a meeting or researching a new topic for a story, I take notes as I go. I try to figure out what’s going on with a new program or make sense of a topic…

For many software developers using generative AI, vibe coding is a double-edged sword. The process delivers rapid prototypes but often leaves a trail of brittle, undocumented code that creates significant technical debt. A new open-source platform, Codev, addresses this by proposing a fundamental shift: treating the natural language conversation with an AI as part of the actual source code. Codev is based on SP(IDE)R, a framework designed to turn vibe-coding conversations into structured, versioned, and auditable assets that become part of the code repository.What is Codev?At its core, Codev is a methodology that treats natural language context as an integral…

Poland is getting serious about declining fertility rates which hit a record low of 1.16 births per woman in 2024. On October 16, 2025, Polish President Karol Nawrocki signed the PIT Zero for Large Families initiative into law. It exempts parents raising at least two children from personal income tax (PIT). This builds on earlier family support policies like the 500+ child benefit program and was first proposed by the president in August 2025 as part of a broader pro-natalist agenda. It applies to biological or adoptive parents (including single parents) with at least two dependent children under 18 years…

As the cold October weather starts to bite and energy prices rise, most of us are pretty nervous about turning the heating on, and are looking for ways to save cash. Turning the thermostat temperature down is one way of doing this, but even for ‘ideal’ temperatures, you’ll only get the maximum cash saving if you maximise your entire system. Best temperature for a thermostat It’s generally accepted that the ideal temperature for a thermostat is between 18°C and 21°C. According to the Energy Saving Trust, turning the thermostat down from 22°C to 21°C will save £90 a year on energy…

For those looking for proof that gen AI is actually having a significant impact on traditional software vendors, they need look no further than Oracle's explosive Q1 results.The database stalwart, founded in 1977, just reported financial metrics that reveal a fundamental transformation in enterprise AI adoption. Oracle's remaining performance obligations (RPO) skyrocketed to $455 billion, representing a 359% increase from last year and a $317 billion jump from Q4 alone. RPO measures contracted revenue that customers have committed to but Oracle hasn't yet recognized, making it a critical indicator of future revenue growth. This massive backlog means Oracle has already…

Samsung may now stick to its usual S series naming schemeWe’ve also heard the S26 Edge may not get a launchThe phones could appear later than normal, sometime in MarchIt would seem the Galaxy S26 development process isn’t going quite as smoothly as Samsung would hope: earlier this week we heard the Galaxy S26 Edge may have been cancelled, and now there are new rumors around launch delays and phone rebrandings.First up, the rebranding. Several previous leaks had suggested that the base model in this series would be called the Galaxy S26 Pro – perhaps to add to the appeal…
