Teenage Engineering has already issued multiple substantial updates for its surprisingly capable $329 EP-133 KO II sampler. Its latest is one of the biggest yet. OS 2.5 adds audio over USB, selectable sample rates for lo-fi fun, sample reverse, an arpeggiator, equal-length autochopping, and it extends the maximum length of a sample from 20 seconds […]

Everyone feared AI would enslave humanity; but it looks like the real fight is stopping governments and Big Tech from enslaving AI for the benefit of the few. Amid the newly announced "regulation" of OpenAI's frontier models, I believe the future majority feared the most - sort of AI becoming a superpower and enslaving people - may be arriving in the opposite form. Not AI enslaving humanity. But AI being captured, controlled, and used by governments and Big Tech for the benefit of the few. So, s

A month ago there was a wave of posts and tweets about engineers walking around cafes and parks with their MacBooks propped half-open, as fully closing the lid forces sleep that stops their AI agents. Some people made snarky comments about using tmux or Amphetamine, and some defended their choice with “but I only need it sometimes, and forgetting to disable Amphetamine and finding my laptop discharged in my bag is worse.” This is a solution to this problem. Unlike caffeinate, it will prevent you

Repo link and results - https://github.com/Abhinand20/MathFormer Task: Given a factorized expression like (7-3*z)*(-5*z-9), predict the expanded form -> 15*z\*2-8\*z-63 Key takeaway: A tiny (4M param) seq2seq model trained with no math knowledge reaches ~98.6% accuracy on symbolic math tasks, suggesting it learns structural token transformations rather than any notion of operators or variables. Scaling this up could help explain why LLMs appear to “reason” mathematically, when they may actually be performing large-scale structured pattern completion. How does RL change this paradigm given the inherent architecture is still based on attention? submitted by /u/AlphaCode1 [link] [留言]

In the landscape of modern programming, delimiters serve as the essential scaffolding that organizes logic and defines structure. Among these, curly braces—often referred to as braces or squiggly brackets—occupy a unique position. While they are ubiquitous, they are frequently the source of developer frustration and logic errors. A common pitfall for many programmers is the tendency to treat all delimiters as interchangeable, leading to a fundamental misunder身 of how a compiler or interpreter parses a script. Confusion often arises when developers conflate the purpose of curly braces with those of parentheses or square brackets. For instance, in many languages, curly braces denote a scope or a code block, whereas square brackets handle indexing. However, the nuances become even more complex when examining specific environments like R, where the semantic meaning of a symbol can shift depending on the context—moving from defining a function to facilitating list extraction. Understanding the specific curly braces semantics is not merely an academic exercise in syntax; it is a practical necessity for writing clean, maintainable code. When a developer understands why a brace is used, they can more easily debug nested structures and communicate intent to their teammates. Grasping these distinctions reduces the cognitive load required to read complex scripts and prevents the subtle bugs that emerge when syntax is used incorrectly. Curly Braces vs. Other Delimiters: Semantic Roles in R and Beyond To master programming syntax, one must move beyond recognizing symbols and begin understanding their semantic intent. While many developers treat curly braces as just another set of punctuation, their role is fundamentally distinct from parentheses and square brackets. Understanding the nuance of curly braces semantics is essential for writing logic that is both functional and readable. The Primary Role: Defining Code Blocks In most procedural and object-oriented languages (such as

Hello Devs 👋 AI coding assistants have changed the way many teams build software. Tasks like generating components, creating tests, writing boilerplate, or handling repetitive refactors can now happen in minutes instead of hours. The productivity gain is real and that part is easy to notice. What becomes interesting after using these tools for a while is that a different bottleneck starts appearing. Code generation becomes faster, but the review process often stays the same. Teams can generate hundreds of lines of code within minutes, but someone still has to answer important questions: Does this actually solve the requirement? Are edge cases covered? Will this introduce side effects? Does it align with existing patterns? The speed of writing code has changed. The need for confidence has not. That is where I think the conversation around AI-assisted development is starting to shift. The challenge is becoming less about generating code and more about making sure the generated code is actually safe to ship. The Problem With Reviewing AI-Generated Code Like Regular Code Imagine asking an AI coding assistant to implement coupon validation for premium users. Add coupon validation for premium users and create tests A few seconds later you get: if ( user . isPremium ){ applyCoupon (); } Nothing immediately looks wrong. The code is clean, there are no syntax issues, tests may pass, and the implementation appears complete. But pull request reviews usually go beyond reading diffs. Reviewers start asking questions such as: What happens if the coupon has expired? Does this affect payment calculations? Should audit logs be updated? Are there services depending on this behavior? This is where AI-generated code becomes interesting. It can often be functionally correct while still missing important implementation details. Research around larger AI-generated projects has also shown that functional correctness does not necessarily translate into maintainable system design. Teams stil

Maraget Atwood, the storied author of The Handmaid's Tale and The Blind Assassin, was interviewed as part of the Babell Literary and Cultural Festival in Porto, Portugal. As it usually does at these things, the issue of AI came up, and Atwood didn't mince words. According to Deadline's recap, Atwood said she'd used an AI […]

Recently saw this comment on another HN thread about the US government gating access to GPT-5.6 and how it harkens back to the 1990s encryption-as-export-controllable-tech situation and how people tattoo'd the algo to their bodies: > I can't wait for the first person to tattoo model weights on their body! (https://news.ycombinator.com/item?id=48693721) And I can't help but wonder, what would be the smallest functional amount of weights from any sort of ML model you could realistically tattoo ont

Google's NotebookLM is great. But handing your research notes, PDFs, and meeting transcripts to Google's cloud is a hard sell for a lot of people — especially when those documents contain client data, unpublished research, or internal strategy. So I spent a weekend testing five open-source alternatives. Three things mattered: can I docker compose up in under 10 minutes, does the podcast feature actually work offline, and what breaks first? Here's what I found. The Contenders Project Deploy Time Min VRAM True Offline License Open Notebook (lfnovo) ~8 min 8 GB Yes MIT Notex (smallnest) ~3 min 4 GB Yes Open source KnowNote (MrSibe) ~2 min 4 GB Yes Open source NotebookLM-Local (nagaforcloud) ~15 min 8 GB Qwen-3 4B bundled Open source InsightsLM (phsphd) ~30 min 8 GB Yes N8N SUS license 1. Open Notebook — The One to Beat git clone https://github.com/lfnovo/open-notebook cd open-notebook docker compose up -d Eight minutes from git clone to the web UI on localhost:3000 . It ships with 18+ model providers pre-configured — Ollama, OpenAI, Claude, DeepSeek, Gemini, all selectable per notebook. The podcast generator supports 1-4 speakers with different voices, and it runs entirely offline when you point it at an Ollama backend. What works: Document ingestion is fast — SurrealDB's vector + full-text index handles 200-page PDFs without choking Model switching is genuinely useful — Claude for deep analysis on one notebook, local Qwen for quick summaries on another Podcast quality with 2 speakers is close to NotebookLM's. 4 speakers is still rough. What breaks: Citation highlighting is still being rebuilt (work in progress as of June 2026) Single-user only — no team/workspace isolation built in Docker required. No native binary. 2. Notex — Single Binary, Zero Dependencies Notex is written in Go. You download a single binary (~25MB) and run ./notex . That's it. No Docker, no Python venv, no database setup. It supports PDF, TXT, MD, DOCX, HTML, audio, and YouTube/Bilibili URLs as so

QR codes look like magic — a grid of black and white squares that encodes anything from a URL to a business card. But how do they actually work? I decided to find out the hard way: implement the full QR Code Model 2 algorithm in vanilla JavaScript, zero external dependencies. The result: QR Code Generator — a free, client-side tool that generates QR codes from any text or URL. 👉 https://qr-code-generator-e83.pages.dev Why No Libraries? I maintain a collection of browser-only developer tools at devnestio . Every tool has the same rule: zero external dependencies. No npm installs, no CDN scripts, no servers. For most tools (JSON diff, Base64 encoder, UUID generator) that's easy. QR codes are different. The spec is a 126-page ISO document. Most developers just npm install qrcode and call it a day. But writing it from scratch taught me more about error-correcting codes, Galois field arithmetic, and matrix encoding than I ever expected. Worth every hour. What the Tool Does Real-time generation as you type (debounced at 80ms) Size selector — 128 × 128, 256 × 256, or 512 × 512 pixels Error correction level — L (7%), M (15%), Q (25%), H (30%) Color picker — any foreground and background color PNG download via canvas SVG download with crisp vector output at any scale How QR Codes Actually Work QR Code Model 2 (the standard you see everywhere) has six major steps. Here's the short version: 1. Data Encoding Text gets encoded into one of three modes based on content: Numeric ( 0-9 ): packs 3 digits into 10 bits — most compact Alphanumeric ( 0-9 A-Z $%*+-./:space ): 2 chars into 11 bits Byte (everything else): UTF-8, one byte per 8 bits The encoder picks the mode automatically and finds the minimum QR version (1–40) that fits the data. function detectMode ( text ) { if ( /^ \d +$/ . test ( text )) return NUMERIC_MODE ; if ( text . split ( '' ). every ( c => ALPHANUMS . includes ( c ))) return ALPHANUM_MODE ; return BYTE_MODE ; } 2. Reed-Solomon Error Correction This is the hard

The question My son was on the sofa with his iPad, poking at the live "Predict the Bracket" game — the whole 2026 World Cup knockout tree on one screen, every slot already filled with the crowd's favourite for that match. Tap a match, see who most people think goes through, watch the picks flow all the way up to a predicted champion. He frowned at it. "Daddy, how do they know which team plays which team? The teams aren't even decided yet." He'd caught something real. The little cards sitting in those slots were only predictions — the crowd's best hunch — but the shape underneath them, who-plays-who and where, was already locked in. Months before a single match kicks off. Fair question. The 2026 World Cup has 48 teams in 12 groups (A through L). The top two of every group go through — that's 24 teams. Then, to round it up to a nice bracket of 32, they also take the 8 best third-placed teams . Twelve groups, but only eight of their third-place teams get a golden ticket. "So you don't know which eight until the very end," he said. "But the bracket's already sitting right there on the screen." "Right." "That's cheating." It isn't cheating. It's one of the prettiest little bits of planning in all of sport, and by the end of the afternoon he understood it better than most adults do. We did it with the dining chairs. The setup, first Before the chairs, my son needed to know where these kids even come from. So we did the boring-but-important part first. A football group is a handful of teams who all play each other. When it's done, the best go forward, the worst go home, and — this is the bit that matters — there's a kid right on the line: the best of the rest , neither safely through nor clearly out. That borderline kid is the star of this whole story. Call them a wandering kid . To learn the trick, let's make the groups nice and small: two groups, A and B, three kids in each — six kids total. In each group the top kid goes straight through to the next round, the bottom ki

Everyone hits the same wall with Claude Code. You add a rule to CLAUDE.md . It works. You add ten more. They mostly work. You add forty more — and now Claude is cheerfully ignoring the rule you care about most, the one that's been sitting there since day one. So you make it LOUDER , in caps, with three exclamation points. It still gets skipped. The instinct is to write more. The fix is almost always to write less . Here's why, and what to do instead. Instruction-following has a budget, and you're overdrawn This is the part most CLAUDE.md guides skip. Frontier models reliably follow on the order of 150–200 instructions at once — and adherence to any single rule drops as you stack more on top of it. It isn't a cliff; it's a slow tax. Every line you add makes every other line a little less likely to be honored. Now subtract what you don't control: Claude Code's own system prompt already spends a chunk of that budget before your file is even read. So the working budget for your project rules is smaller than the headline number — and a sprawling 300-line CLAUDE.md isn't 300 rules followed, it's maybe the first 150 followed well and the rest treated as ambience. The mental model that fixes everything downstream: CLAUDE.md is a budget, not a wishlist. You are not writing documentation. You are spending a scarce attention allowance, and every line competes with every other line. The test for every line: would you bet $5 it's followed? Go through your file line by line and ask one question of each rule: would I bet money this fires every time it's relevant? Three outcomes: Yes, and it's load-bearing — keep it. This is what the budget is for. Nice to have, but I wouldn't bet on it — cut it, or move it to a referenced file (below). It's diluting the rules you would bet on. It absolutely must happen every time — then it doesn't belong in CLAUDE.md at all. Make it a hook. That third category is the one people get wrong, so let's be concrete about it. Advisory vs. deterministic:

A checkout saga spans inventory, payment, shipping, and loyalty. Downstream latency shifts every hour. Black Friday is not the day to discover your payment step timeout is baked into application.yml across twelve Spring Boot services. Kiponos.io gives every saga participant the same live orchestration parameters — step timeouts, retry budgets, compensation triggers — via one shared config tree. Each JVM reads locally on every saga step; ops adjusts once in the dashboard; WebSocket deltas propagate without redeploying the fleet. Why sagas break with static config Typical saga coordinator code: if ( step . elapsedMs () > 8000 ) { compensate ( "payment" , sagaId ); } That 8000 usually comes from: Per-service YAML — payment service says 8s, inventory says 12s; nobody agrees during an incident Env vars in Helm — change means rolling twelve deployments Shared DB config table — poll per step adds latency and coupling Saga steps are high-frequency reads inside workflow engines. You need local memory reads and async updates — the same contract as live API rate limits . Architecture: one tree, many participants ┌─────────────────┐ WebSocket deltas ┌──────────────────────┐ │ Kiponos.io UI │ ────────────────────────► │ Inventory service │ │ platform ops │ │ Payment service │ └─────────────────┘ │ Shipping service │ │ (each: in-mem SDK) │ └──────────┬───────────┘ │ .getInt() local ▼ ┌──────────────────────┐ │ saga step executor │ └──────────────────────┘ Every participant connects to profile ['orders']['v2']['prod']['sagas'] . When NOC extends payment.step_timeout_ms , all JVMs see the new value on the next step — no config server poll, no inter-service "what is timeout now?" REST calls.
