AI infrastructure spending is still accelerating, especially in data centers and advanced chip production. While most attention goes to chip makers, the companies enabling that ecosystem may have a longer runway. Do any of you work in similar companies and can give a broader perspective on it ? Teradyne sits in a pretty interesting spot. More AI chips being produced means more testing capacity is needed, and this is one of the key players in semiconductor testing equipment. Could testing equipment companies outperform some of the more crowded AI trades over the next few years? For me personally I feel like AI hardware growth probably creates winners beyond just the obvious names, and TER seems like one of the more overlooked candidates. I learned they are also being listed on bitget recently so looking at a bigger picture we are watching a lot of growth happening in Ai infra. submitted by /u/Stunning-Ask3032 [link] [留言]

Seems like they have engineered some specific limitations that are widely cited as follows: In light of the ability of recent models to accelerate their own development, we’ve implemented new interventions that limit Claude’s effectiveness for requests targeting frontier LLM development (for example, on building pretraining pipelines, distributed training infrastructure, or ML accelerator design). Using Claude to develop competing models already violates our Terms of Service, but enforcing this restriction through our safeguards avoids accelerating the actors most willing to violate these terms. Unlike our interventions for cybersecurity, biology and chemistry, and distillation attempts, these safeguards will not be visible to the user. Fable 5 will not fall back to a different model. Instead, the safeguards will limit effectiveness through methods such as prompt modification, steering vectors, or parameter-efficient fine-tuning (PEFT). These interventions will not affect the vast majority of coding work. We estimate they will impact ~0.03% of traffic, concentrated in fewer than 0.1% of organizations https://news.ycombinator.com/item?id=48464732 Other comments note how even using the word 'nuclear' in the context of scientific research elicits refusal behavior by the model: https://news.ycombinator.com/item?id=48473302 This makes it seem quite plausible that the model could subtly sabotage any machine learning work (even as false positive). Some suggest this has been happening behind the scenes for a while already, but can anyone confirm that? submitted by /u/AccomplishedCat4770 [link] [留言]

After over a decade, Steam will no longer sell physical gift cards in stores. In a support page spotted earlier by Windows Central, Valve says it will no longer restock its gift cards once they run out, citing scammers who "continue to have an impact on Steam customers and other unsuspecting individuals." In its post, […]

A cybercrime group known as The Gentlemen has emerged as the second most active ransomware gang by victim count, rapidly attracting a talented pool of hackers through an aggressive recruitment strategy that promises affiliates 90 percent of any ransom paid by victims. This post examines clues pointing to a real life identity for the administrator of The Gentlemen ransomware group.

The ACLU is suing two Florida police departments over the arrest of a Fort Myers man in a child-abduction case, saying officers treated a flawed face-recognition match as a near-certain ID.

The funding round was led by Norwest, with participation S Capital VC, Cerca Partners, and Oceans Ventures. Snowflake Ventures also participated as a strategic investor.

Violent threats against lawmakers have also surged on Facebook.

Did the mistake of shopping at adidas website and now I regret it. I should have heeded the warning signs from the massive amount of page flickers, jitters, random scrolling, popups and the fact it just completely freezes a fairly new iphone. It is that heavy. Filtering and searching is just call to a random generator that spits out whatever you did not search for. The login forces passkey instead of simple password. Oh and it also doesnt work to login. Tracking your order is a mere mirage they put there in words but is yet to be vibe coded. Do you believe this type of website is developed in house or outsourced? submitted by /u/GrumpyBitFlipper [link] [留言]

Your CI was green last Friday. Today, the payments test is failing. Somewhere between Friday's merge and now, 47 commits landed on main . Which one broke it? Most developers answer this the wrong way: they scroll through git log , check out suspicious commits one by one, and run the test manually. An hour later, they're still guessing. There's a command built for this exact problem. It's called git bisect , and once you learn it, you'll never debug regressions the old way again. How bisect works git bisect is a binary search across your commit history. You tell Git two things: A good commit (a known point where the bug didn't exist) A bad commit (a known point where the bug exists — usually HEAD ) Git then checks out the commit halfway between them. You test. You mark it as good or bad. Git narrows the range by half. Repeat. With 47 commits between "good" and "bad", it takes at most 6 steps (log₂ 47) to find the exact commit that introduced the bug. Versus checking every commit manually, that's the difference between 5 minutes and an hour. The manual workflow # Start a bisect session $ git bisect start # Mark the current state (HEAD) as bad $ git bisect bad # Mark a known-good commit $ git bisect good a3f1d22 # Bisecting: 23 revisions left to test after this (roughly 5 steps) # [7e4b9c1] refactor: extract payment validator # Git has checked out a commit in the middle. Run your test. $ npm test -- --grep "payments" # Test passed — mark this commit as good $ git bisect good # Bisecting: 11 revisions left to test after this (roughly 4 steps) # [b2d8e11] feat: add retry logic to payment API # Test failed — mark this commit as bad $ git bisect bad # ... continue until Git announces the first bad commit: # b2d8e11 is the first bad commit # commit b2d8e11 # Author: leo@company.com # Date: Tue Apr 15 11:42:03 # feat: add retry logic to payment API # Done — reset to where you started $ git bisect reset In 6 commands, you know exactly which commit broke the tests. No guessing

You built a workflow worth sharing — and it works perfectly. Until someone else imports it. The bottleneck is the API key. Use yours, and every user is billed against your account. Use theirs, and they each have to find the credential UI, paste their key, and reconnect every time. Both are friction. The cleaner option is to let the workflow ask for the key on the form, then thread it through to the HTTP nodes that need it. It's simpler than it sounds. This post walks through the pattern with a working credential setup, an alternative for single-node simple cases, the gotchas, and a note on what this enables for custom node authors. The screenshots below come from n8n's built-in Bearer Auth credential and from the n8n-nodes-ldxhub package's own credential schema. The technique itself is generic — what's shown here works for any HTTP-node workflow and any custom node that supports expression-mode credentials. The form asks, the credential listens The simplest case: a Form Trigger collects an API key, then an HTTP node hits an authenticated endpoint with that key. Two nodes, one bridge between them — but the bridge isn't a direct expression. It runs through a credential. The flow: Form Trigger collects api_key (use the Password element type for masking) A Bearer Auth credential references that form input via expression HTTP node picks the credential The Form Trigger is straightforward. Add one field: Form Trigger Form Fields : - Label : API Key - Element Type : Password - Custom Field Name : api_key - Required Field : yes Element type matters. Use Password instead of Text and the input gets masked on screen — the key isn't readable to someone glancing at the browser. Here's the rendered form a user sees when they open the workflow URL: Wiring the credential to expression mode For a Bearer token (which is what most modern APIs use), create a new credential of type Bearer Auth — a generic credential built into n8n that's purpose-built for Authorization: Bearer ... header

Uber's CTO told the world this month that the company spent its entire 2026 AI allocation by April. The story has been reported in a handful of outlets, hit the front page of Hacker News for 397 points and 469 comments , and is mostly being read as a cost-of-AI-tools story. It is one. It is also, on a closer reading of the numbers, a pricing-model story — and the structural fact that almost none of the coverage has emphasized is the one that determines whether this is a one-company anomaly or the beginning of an industry-wide budgetary crisis. The structural fact is that Claude Code, like most enterprise AI tooling in 2026, is priced on token consumption, not per-seat licensing. Token-based pricing scales with how aggressively the tool is used. Per-seat enterprise SaaS pricing — the model corporate IT budgets are built around — scales with how many people have access to it. Those two cost curves diverge in exactly the territory where productivity tools are designed to operate: high-engagement, daily-use, gradually-deepening workflows. The Uber data is the first public-facing version of a math problem most enterprise IT departments are about to discover privately. The numbers Uber CTO Praveen Neppalli Naga , named in Yahoo Finance's and Benzinga's coverage, said publicly that Uber is "back to the drawing board" on AI budgeting after the surge in Claude Code use blew through internal projections. The specific numbers, as reported across the multiple outlets covering the story: Claude Code adoption inside Uber's ~5,000-engineer organization went from 32% to 84% over four months. 70% of committed code at Uber is now AI-originated. 11% of live backend updates are "being written by AI agents built primarily with Claude Code," per the reporting. Per-engineer monthly API costs: $500 to $2,000. Uber's annual R&D spend is around $3.4 billion , of which the AI tooling line was a much larger fraction than expected. Cursor adoption plateaued; Claude Code dominated. These are ext
