Show HN: A modern C++20 AI SDK (GPT‑4o, Claude 3.5, tool‑calling)

Hi all, I’m hacking on new features for the ClickHouse native client and wanted the same “just call the model” ergonomics JavaScript and Python now enjoy. It didn’t exist for modern C++, so I wrote one. ai‑sdk‑cpp (Apache‑2.0) gives you: - Unified calls to OpenAI (GPT‑4o) and Anthropic (Claude 3.5) with a single C++20 API. - Streaming, multi‑turn chat, error handling—all std::optional/std::variant, no macros. - Tool calling (function‑calling) so the model can hit real APIs; sync or async, run

Amazon Reaches Automation Milestone by Deploying Its Millionth Robot

Amazon's fleet of warehouse robots just hit a new milestone. The company announced Monday that it deployed its millionth bot to begin operations at a fulfillment center in Japan.

The robotic workers operate in over 300 Amazon wareh

FCC chair decides inmates and their families must keep paying high phone prices

Federal Communications Commission Chairman Brendan Carr has decided to let prisons and jails keep charging high prices for calling services until at least 2027, delaying implementation of rate caps approved last year when the FCC had a Democratic majority. Carr's office announced the change yesterday, saying it was needed because of "negative, unintended consequences stemming from the Commission's 2024 decision on Incarcerated People's Communications Services (IPCS)... As a result of this waive

Figma moves closer to a blockbuster IPO that could raise $1.5B

Figma publicly shared its financials Tuesday, inching the design software company closer to an IPO. And while this initial S-1 is missing details such as number of shares to be offered and what price, the regulatory filing provides the clearest view yet of its financial health — and potential. IPO experts Renaissance Capital estimate that Figma could raise up to $1.5 billion in this offering. If it does meet or exceed that, Figma’s IPO will match or beat CoreWeave’s, which raised $1.5 billion a

Google’s data center energy use doubled in 4 years

No wonder Google is desperate for more power: The company’s data centers more than doubled their electricity use in just four years. The eye-popping stat comes from Google’s most recent sustainability report, which it released late last week. In 2024, Google data centers used 30.8 million megawatt-hours of electricity.

Email is already the “number-one use case” of Grammarly for professional users, the company says, with “the AI assistant helping to revise over 50 million emails per week across more than 20 email providers.” Buying Superhuman makes some sense, then: it gives Grammarly its own email app t

Tesla's Stock Has Fallen Dramatically Since Elon Musk Returned to the Business

When multi-hyphenate billionaire Elon Musk returned to Tesla in May, it was met with a surge of enthusiasm from investors who feared he'd given up on the embattled carmaker during his disastrous stint in government. But that optimism has dimmed significantly as Musk has brought his signature aura of chaos and disappointment back to Tesla — and it's clear in the company's stock price, which has actually fallen since his homecoming in late May. At the time, the company's share price was hovering

Amex and Chase Both Changed Welcome Bonus Terms for Popular Credit Cards. Here's Why That Matters

CNET/Getty Images A credit card's welcome offer is generally one of the main incentives for applying for a credit card. So what happens if the card issuer no longer discloses how much you earn before you apply, or changes its rules around who's eligible and who isn't? American Express recently changed the language for the terms on the Platinum Card® from American Express and the American Express® Gold Card. The card issuer no longer specifies the exact number of points you can earn for the car

The first 5 Linux commands every new user should learn

Jay Dickman/Getty Images I remember when I started using Linux in the late 1990s. Back then, using the command line wasn't optional. If you worked with the open-source operating system, you had to spend time in the terminal. Using the command line in the past was challenging because there wasn't as much help as today. I was pretty much on my own. Thankfully, I struggled through and became proficient. With the help of man pages (manual pages for commands), I survived those early days. Of course
