EDRSR — the Unified State Register of Court Decisions — is effectively all of Ukraine's judicial practice in open access. Today Qdrant holds **44M+ vectors : criminal (19M), civil (14.3M), commercial (5.1M), misdemeanors (5.6M). Vectorization of civil cases (CPC, justice_kind=1) — the largest cohort at 33.7M documents — runs on a dedicated EC2 instance (r6a.xlarge, 32 GB RAM, 2 TB gp3). Here's what's under the hood: models, pipeline, cost, rakes, and current status. Why Vectorize Courts When a lawyer searches "is there case law on recovering bank prepayment fees" — they don't want to open 40 decisions and read them through. They want the system to surface the top 5 most relevant ones, pull out key paragraphs, and show how courts reasoned. Full-text search (FTS) over keywords doesn't give that — it returns every document containing the word "fee", and there are thousands. For this semantic task you need vector representations of text. The model turns a paragraph from a decision into a point in a 1024-dimensional space; semantically similar paragraphs sit near each other. A kNN search in Qdrant returns the top K nearest, and an LLM composes the answer from exactly those relevant fragments. The only problem: the register is big. Very big. Scale Our prod database holds full texts of decisions starting from 2006. Breakdown by procedural type: Civil (CPC) — 33.7M documents. The largest category. Consumer, housing, labor, family. Criminal (CrPC) — 12M+ Administrative (CAS) — 14M+ Commercial (CC) — 6M+ Misdemeanors (CUaP) — 6M+ The Qdrant collection edrsr_decisions on a dedicated EC2 currently holds 44M+ vectors (122 segments, on_disk=true): | Proceeding type | justice_kind | Vectors | |—|—|—| | Criminal (CrPC) | 2 | 19,036,347 | | Civil (CPC) | 1 | 14,328,427 | | Misdemeanors (CUaP) | 5 | 5,579,432 | | Commercial (CC) | 3 | 5,098,662 | | Total | | 44,042,868 | Civil cases processed: 14.3M out of 33.7M — that's 42%. After CPC completes there will be roughly 63M+ vectors in

In production we have ~1.5 TB of full-text court decisions and their vector embeddings, plus another ~550 GB of other legal data: registries, legislation, business entities, a Spanish case law corpus, EU-Lex. If we take this corpus and train an MoE model the size of DeepSeek V3, scaled to 860B parameters, on GCP — what comes out? We break down the dataset, architecture, compute cost, and the properties such a model would have on Ukrainian law. What's in the Dataset The entire corpus is what's already running in SecondLayer's production. No extra scrapes, no Common Crawl, no noise. EDRSR — the dataset core, ~1.5 TB. The Unified State Register of Court Decisions of Ukraine. 96.2 million full-text decisions (1,079 GB in PostgreSQL TOAST), 471 GB of vectors in Qdrant (voyage-3.5, 1024-dim), 28 GB of metadata (court, judge, date, case category, proceeding type, statute code). Breakdown by jurisdiction: civil 33.7M, administrative 14M+, criminal 12M+, commercial 6M+, misdemeanors 6M+. Largest annual cohort — 2024 (115 GB of TOAST text). OpenReyestr — 43 GB. Ukrainian public registries: 16.7M legal entities (EDR), ownership structures (beneficiaries, shareholders), debtors (State Enforcement Service), NAIS registries. This is the foundation for SneakyPiper — our due-diligence platform — but here it serves as raw corpus for the model. Legislation — ~40 GB. The Constitution, major codes (Civil, Criminal, Criminal Procedure, Civil Procedure, Commercial Procedure, Administrative Procedure, Labor, Tax, Customs), laws, and secondary legislation. All structurally annotated: articles, parts, clauses, revision dates with effective-date tracking. This isn't flat text: we know that Article 124 of the Constitution took effect on a specific date, carries particular references, and is cited in a precise number of decisions. Supreme Court review practices + lu_court_decisions — ~25 GB. SC plenary decisions, practice overviews, Grand Chamber rulings. This is the most valuable slice — the

I build and run one of the tools on this list (AGenO — full disclosure below), and I use every other tool here regularly. This is what "free" actually gets you on each one, including the catches. The AI tool landscape has a dirty secret: almost nothing labeled "free" is free. Most tools give you a taste — ten messages, three images, one song — and then the paywall lands. So instead of another list of forty tools nobody has tried, here are nine that give you real value at $0, organized by what you're trying to make, with the actual limits spelled out. Quick comparison Tool Best for What's actually free The catch ChatGPT General chat & writing ~10 msgs/5h on the flagship model Silently switches you to a weaker model after the limit Claude Long documents, nuanced writing 10–25 msgs/5h, varies with demand Limits shrink when servers are busy Gemini Image generation & editing Generous with a Google account Best features drift to the paid tier Perplexity Research with citations Unlimited basic searches Pro searches are capped Suno AI music ~10 songs/day No commercial use on free; failed generations can eat credits Leonardo AI Stylized art & game assets Daily token allowance Confusing token system; images are public on free Character.AI Roleplay & AI characters Unlimited chat Heavy filters; your chats train their models AGenO All of it in one place Images, songs with vocals, chat, characters, stories, coding problems — daily free allowance One-person project — busy hours can mean a short queue Canva Magic tools Quick social graphics 50 text-to-image uses Design-tool add-on, not a real generator Chat and writing ChatGPT is still the default for a reason — the free tier includes the flagship model and it's good at nearly everything. The catch nobody tells you about: after roughly ten messages in five hours, it quietly downgrades you to a mini model without making it obvious. If your answers suddenly get dumber mid-conversation, that's why. Claude writes the most natural prose

Google Trends has no official API, and most wrapper libraries rot within months. But the Trends site itself runs on a keyless JSON API that anyone can call, and it serves the exact numbers you see in the UI. Here is the full recipe, including one gotcha where Google quietly labels your session a scraper. The two step flow Trends works in two steps. First you call explore , which returns a list of widgets, one per chart on the page, each with a signed token: GET https://trends.google.com/trends/api/explore ?hl=en-US&tz=0 &req={"comparisonItem":[{"keyword":"web scraping","geo":"US","time":"today 12-m"}],"category":0,"property":""} Then you call a widget data endpoint with that widget's request and token : GET https://trends.google.com/trends/api/widgetdata/multiline?hl=en-US&tz=0&req=<widget.request>&token=<widget.token> The widget kinds map to endpoints: TIMESERIES uses multiline , GEO_MAP uses comparedgeo , and both RELATED_QUERIES and RELATED_TOPICS use relatedsearches . The cookie trick Call explore cold and you get a 429. The API wants a NID cookie, and here is the counterintuitive part: you get it by requesting the public explore page first, and that page may itself respond 429 while still setting the cookie you need. const res = await fetch ( ' https://trends.google.com/trends/explore?geo=US&q=test ' ); // res.status may be 429. The Set-Cookie header is still there. const cookies = res . headers . getSetCookie (); Grab the cookie from the 429 response, retry explore , and everything works. Strip the anti JSON prefix Every Trends response starts with a junk line like )]}' to break naive JSON.parse calls. Drop everything up to the first newline: const body = await res . text (); const data = JSON . parse ( body . slice ( body . indexOf ( ' \n ' ) + 1 )); The scraper flag Here is the part I have not seen documented. Look inside the widget request object that explore returns to a keyless session: "userConfig" : { "userType" : "USER_TYPE_SCRAPER" } Google knows. And

Hi everyone, I want to share textparser, a high-performance, lightweight text parsing and AST generation library written in pure C. 💡 The Core Idea & Why It's DifferentTraditional parser generators (like Flex/Bison) come with a steep learning curve and rigid code generation. On the other end, hand-writing recursive descent parsers or state machines becomes an unmaintainable mess as your language grows.textparser bridges this gap using a hybrid JSON + Python + C workflow:You define your tokens, syntax patterns, and color styles in a clean, human-readable JSON grammar file. A lightweight Python compiler tool processes the JSON, runs optimizations, and emits a dense, static C header array.The C runtime engine loads these pre-compiled arrays instantly. It processes raw text strings into an abstract token tree (textparser_token_item) using a highly optimized regular expression engine (crpe2).By offloading the grammar overhead and heavy state-machine parsing logic to the Python build step, the actual runtime C library stays incredibly lean, memory-efficient, and fast. 🚀 Features At A Glance30+ Languages Out-of-the-Box: Includes ready-to-use JSON grammars for C, C++, Rust, Python, JavaScript, HTML, SQL, and dozens more.Rich Token Metadata: Every parsed token tracks exact code coordinates, structural flags, and custom syntax styling options.Zero Bloat: Ideal for terminal text editors, syntax highlighters, custom linters, and lightweight static analysis tools where bringing in a massive compiler front-end is overkill.

The rise of AI has brought an avalanche of new terms and slang. Here is a glossary with definitions of some of the most important words and phrases you might encounter.

This week, researchers at the University of Minnesota announced something that genuinely stopped me mid-scroll. A team led by Associate Professors Kate Adamala and Aaron Engelhart built the world's first synthetic cell with a complete life cycle — not modified from an existing organism, not borrowed from biology. Built. From. Scratch. They're calling it SpudCell . It can grow. It feeds. It copies its own genetic material. It divides into new cells. And it does all of this from a starting point of pure chemistry — non-living components assembled with intent. Adamala put it plainly: "We've replicated in chemistry what only used to be possible in biology: the complete set of behaviors of a cell. It proves that the most fundamental functions of life, like growth and replication, do not need a mysterious magical spark." — University of Minnesota That's not hype. That's a scientist who has spent her career working toward this moment, choosing her words carefully. What SpudCell Actually Is SpudCell isn't a copy of a bacterium or a stripped-down version of an existing cell. It's a chemically defined system — meaning researchers know the full ingredient list, every molecule at every concentration. To put the scale in perspective: the human genome runs about 3 billion base pairs. SpudCell's genome is 90 kilobase pairs. Minimal by design. But minimal doesn't mean simple — it means precise . Every component earns its place. — CBS Minnesota The cell mostly resembles a basic bacterium in its behavior, but it carries none of evolution's baggage. No millions of years of accumulated quirks. No legacy code. Just the essential machinery for life's core functions, assembled on purpose. Yuval Elani, a synthetic biology researcher at Imperial College London, framed it this way: "Building a cell from scratch means you are no longer tied to the constraints and evolutionary baggage of natural biology. It opens up the possibility of designing systems and programming them to do things that li

Hi everyone, I built H64LM, a research project to better understand modern LLMs by implementing one from scratch in PyTorch. Instead of relying on high-level training frameworks, I implemented the core components myself attention, MoE routing, normalization, and the training loop. Features 249M-parameter Transformer Grouped Query Attention (GQA) Sparse Mixture-of-Experts (8 experts, Top-2 routing) with 3 auxiliary routing losses SwiGLU, RoPE, RMSNorm Sliding-window attention Mixed-precision training, gradient accumulation Custom training loop (no Trainer abstractions) Checkpointing and resume support The included checkpoint was trained on a subset of WikiText-103 to validate the pipeline end-to-end, not to be a strong model it's visibly overfit past epoch 10 (best val PPL ~40.5). Known limitations are documented in the README, including batch-size-1-only generation and no true DDP (falls back to DataParallel). GitHub: https://github.com/Haiderkhan64/H64LM Feedback on the implementation or architecture is very welcome. submitted by /u/Loose_Literature6090 [link] [留言]

There's a phase almost every developer gets stuck in. You're consuming tutorials, bookmarking articles, finishing courses, and buying books you'll read "eventually." You're learning constantly — but you're not producing anything. You're just... absorbing. That's the learning vacuum. And if you've been there, you know how easy it is to confuse staying busy with making progress. At some point, the shift has to happen. You stop being a sponge and start being a signal. Here's how I started making that turn. Start a Daily or Weekly Code Journal You don't need a blog, a brand, or an audience for this. Just a file. A note. Anything. Write down what you built, what broke, and what you figured out. Even one sentence counts. I like to write a quick sentence and how many hours, just like if you were filling in an invoice for contract work. The act of putting it into words forces you to actually process what you learned instead of letting it blur into the background noise of your brain. Over time, those entries start to look like a roadmap — and you realize you've come further than you thought. Code Something You Actually Want to Build Pick something dumb. Pick something fun. A browser game, a weird UI experiment, a tool that solves exactly one tiny problem in your life. I signed up for DEV Challenges , Summer Bug Challenge and upcoming Weekend Challenge to get my ball rolling. The best projects I've ever worked on had no real-world utility. They were just interesting to me. And that interest kept me showing up even when things got hard. A tutorial can't give you that. Only a project you actually care about can. Find Your People Whether it's here or a Discord server, a local meetup, a dev community on Farcaster or Lens, or just a forum thread you keep coming back to — find somewhere to show up regularly. Lurking is fine at first. But eventually, drop a comment. Answer a question you know the answer to. Share something you built. Community is where isolated learning becomes shar
