EU chief opens door for Canada to become 'associate member' [comments]

660 points · 845 comments · www.bbc.com · 22h ago

The EU chief endorsed a proposal for Canada to become the bloc's first "associate member," a status that doesn't yet exist, as a response to strained US relations and Trump's tariff threats. The discussion veered significantly into a broader ideological scrap over whether "middle power democracies" like Canada and European nations are hobbled by bureaucratic overregulation versus the US and China's embrace of entrepreneurship, with one side arguing European red tape suffocates startups and the other countering that American capitalism is just well-disguised corporate cronyism. A fierce sub-argument erupted over corruption and quality of life, with some claiming Canada is "corrupt as hell" and Europeans pay more in taxes for worse healthcare, drawing sharp rebuttals about US deficits and the SNC-Lavalin scandal. There was also a minority but vocal take that China has "already won" the global struggle, citing US missile depletion and dollar weaponization pushing countries toward Beijing, though others dismissed that as premature. The thread's energy split between realpolitik alignment debates and a raw, sometimes bitter culture-war exchange about which economic model actually delivers for ordinary people.

Mistral X Mozilla: Private, Multilingual AI Browsing [comments]

563 points · 192 comments · mistral.ai · 23h ago

The linked announcement covers Mistral teaming up with Mozilla to power Firefox’s new Smart Window AI assistant, pitching it as private, multilingual, and culturally tuned via regional fine-tuning, with zero data retention promises. HN immediately pushed back on the “private” framing, with several people digging into Mozilla’s own privacy policy to show that prompts actually go through Mozilla servers first before hitting Mistral’s cloud, and that an on-device model only classifies queries locally—so it’s clearly not local inference, despite the headline vibes. A recurring sore point was Mozilla’s apparent about-face from its 2022 Project Bergamot stance, where it championed fully local translation as the gold standard for privacy, leaving some users feeling the org has drifted into cloud-dependent “trust me bro” territory. There’s also a separate tangent on Mozilla’s market-share death spiral, with one participant arguing that Firefox’s decline is 97% Google’s distribution grip rather than feature missteps, while others counter that constant gimmicks (like Pocket or sponsored new-tab links) have eroded goodwill among the very power users who used to evangelize it. The thread splits mostly between defenders noting you can disable the AI or run local models yourself, and critics who see this as just another way to funnel browsing history into a third-party LLM, with one sharp catch about a broken hyperlink on Mozilla’s support page that points to OpenAI’s model card instead of Mistral’s.

Training a 4B model to produce 81% faster query plans than Postgres [comments]

525 points · 109 comments · rohanbansal.com · 13h ago

The article walks through training a 4B-parameter language model to generate `pg_hint_plan` hints that steer Postgres toward faster query plans, claiming a 1.81x geometric mean speedup on join-heavy SQL after superfine-tuning and reinforcement learning. HN’s main pushback centers on the narrow setup — an 8GB in-memory dataset, warmed caches, and read-only SELECTs — with several people arguing that the static hints would fall apart under real OLTP workloads or stale statistics, and questioning whether the ~95 hours of training compute was even factored into the benchmarks. A side tangent spun off into whether LLM-generated plans could ever beat handcrafted heuristics, with one comparison to chess engines needing external rule checks, while another commenter noted that the approach resembles traditional query-optimizer research and might not generalize beyond the toy IMDb schema. There’s also a joke about the write-up being too long, plus a weird political detour where people got into a heated debate about model distillation ethics and whether US companies have any moral standing on the issue, drawing parallels to the Apple vs. Microsoft history of "stealing" ideas. Overall, the split is between those who see this as a promising proof-of-concept for machine-learned query optimization and those who think it’s overfit to a trivial benchmark, with a few folks suggesting CUDA-accelerated Postgres or deterministic algorithms as better bets.

Small programming tricks [comments]

499 points · 221 comments · will-keleher.com · 16h ago

The linked article wasn't available to this summarizer; from the discussion, the post is a collection of small, high-leverage programming and CLI tricks—things like `ctrl+r` with fzf, `git log -S` pickaxe, `SELECT` without `FROM`, and using `rg` over `grep`. The big detour the comments took was straight into an existential debate about whether these tricks even matter anymore, with a big split between people who still hand-code everything and say LLMs are slower or wrong for their niche, and academics who say they barely code by hand at all now and use LLMs for exploration and discovery. A side argument flared up around the idea of "avoiding branches" in code, with someone defending it as a legit optimization and readability win, while others pushed back that it's often just obfuscation—though a few concrete examples of branchless Rust and early returns were shared to show where it actually pays off. There's a real sense of two generations of developers talking past each other, with the old guard insisting on the joy and speed of direct coding while the new wave treats the terminal tricks as increasingly obsolete. The thread also surfaces the social problem of sharing these tips at work—what's obvious to you might be arrogant to state, even when it's genuinely useful to someone else.

Xiaomi Mimo 2.6 live post-training dashboard [comments]

419 points · 100 comments · mimo.xiaomi.com · 11h ago

Xiaomi dropped a live dashboard for its Mimo 2.6 post-training runs, showing real-time step counts, benchmark scores, and even the occasional infra hiccup (two restarts for VRAM and dataset errors so far). The HN crowd mostly split between marveling at the novelty of a Chinese lab live-streaming RL training while Anthropic and OpenAI keep their runs behind closed doors, and practical users sharing war stories—one dev says Mimo's been their daily driver for Rust work, though another dismisses it as noticeably dumber than Qwen 3.8 or GLM 5.3 for coding. A side argument broke out over whether this openness is genuine or just cheap marketing, with one person pointing out Xioami charges far less than Claude and another accusing US labs of being allergic to transparency for IPO reasons. The benchmarks themselves (DeepSWE scores around 60-65) drew some eyebrow-raising about potential overfitting since they're used as validation criteria, though the counterpoint was that it's not the same as training on them directly. The most memorable tangent: someone trying to prove Mimo's coding chops by shipping a 3D game built in a day with it, while another person bitched that Claude's UI style is instantly recognizable because it "can't write a clear sentence without all-caps and gradients."

The Google Play app review process now regularly takes longer than a week [comments]

349 points · 334 comments · gultsch.social · 20h ago

The linked article is a Mastodon post from Daniel Gultsch, the developer of the Conversations XMPP client, complaining that Google Play review now regularly takes over a week for his long-established app, blaming the pileup on AI-generated slop and asking Google to prioritize older apps that ship monthly updates. The HN discussion largely validates his frustration, with many developers sharing similar horror stories: one notes their app with Android Auto support now takes two to three weeks, while others point out that dropping that feature drops review time to hours. A significant split emerges between those defending some form of gatekeeping—arguing that unfettered sideloading would open the door to mass malware infections, even invoking lawnmower liability analogies—and those who see the whole app store model as infantilizing and a regulatory overreach that only benefits mega-corporations. The thread also veers into a defense of F-Droid as an alternative, though a commenter notes its build queue is also slow, and includes a practical tip: an AnkiDroid maintainer chimes in that while their app is stuck in Google’s pipeline, they’ve already published the same build on F-Droid, and another developer shares an AI-assisted workflow for automating the tedious "edge-to-edge" screen migration that Google mandated. Overall, the mood is one of resigned, dark humor about Google’s "bot-driven" process, with the usual caveat that some devs report sub-hour approvals, suggesting a mysterious, inconsistent prioritization that seems to disadvantage those who don't feed the ad/tracking ecosystem.
