Don't just jump straight into a pool with your phone, you savage.

I've been chasing the question of what algorithms a transformer can actually express -- separate from what it can learn. So I built a compiler: define a computation graph in ordinary Python, and it produces the weights of a transformer that executes the graph. The result is a standard Phi-3-architecture checkpoint that vanilla huggingface loads with no custom code and no trust_remote_code. Zero training in the pipeline. Write-up (origin + how the constructions work): https://ood.dev/posts/torchwright-intro/ Repo (twelve runnable examples): https://github.com/physicsrob/torchwright Hand-built transformer weights aren't a new idea. RASP defines a language whose primitives map onto transformer sublayers, and Tracr compiles RASP programs into actual weights. I wanted two things they don't aim for: expressing a computation graph in ordinary Python, and targeting a stock architecture, so the output loads in vanilla huggingface with no custom code. submitted by /u/notforrob [link] [留言]

Let's be honest we mostly wrote about this because we think it's really cute.

The MCP (Model Context Protocol) ecosystem is growing fast. There are now hundreds of MCP servers available — but how do you know which ones are worth installing? After building and evaluating 60+ MCP servers ourselves, we developed a practical checklist that saved us from shipping broken tools. Here's the framework we use. The Problem Most MCP server listings tell you what the server does. Very few tell you how well it does it. You install something that sounds perfect, then discover: It activates on the wrong prompts (false positives) It pulls irrelevant context (retrieval drift) It sounds confident but gives wrong answers (ungrounded reasoning) It never improves from feedback Sound familiar? The 5-Dimension Evaluation Checklist Before installing any MCP server, ask these questions: 1. Trigger Precision Question: Does this server activate when (and only when) it should? Red flags: Overly broad trigger descriptions ("use for anything related to X") No documented activation conditions Activates on common words that appear in unrelated contexts Green flags: Specific, documented trigger scenarios Clear non-activation cases listed Tested against diverse prompts 2. Retrieval Quality Question: Does it pull the right context for the task? Red flags: Returns large chunks without filtering No citation or source tracking Retrieves plausible but outdated information Green flags: Targeted, minimal context retrieval Source attribution for every piece of context Version-aware (knows when data might be stale) 3. Reasoning Grounding Question: Are its conclusions tied to actual data? Red flags: Generates advice without referencing specific inputs Can't explain its reasoning chain Confident answers that contradict its own retrieved context Green flags: Every conclusion references specific evidence Explicitly flags uncertainty Gracefully handles missing information 4. Output Usefulness Question: Does the output actually solve your problem? Red flags: Generic responses that could appl

AI companies including Nvidia and Mistral urge policymakers to avoid broad restrictions on open-weight AI models as Washington debates responses to Chinese AI and alleged model distillation.

Many online image converters require users to upload their files to a remote server before processing. For ordinary images this may be acceptable, but for personal photos, screenshots and documents, privacy becomes an important concern. I built a lightweight online image converter that processes images directly in the browser. It currently supports: JPG PNG WebP HEIC GIF SVG BMP TIFF Why browser-based processing? The main goal was to make image conversion simple, fast and privacy-friendly. Because the conversion happens locally: Images are not uploaded to a server Users do not need to create an account There is no installation process Network upload time is avoided Private files remain on the user’s device The basic workflow is simple: Select an image Choose an output format Convert the file Download the result Challenges Browser-based image conversion still has some limitations. Different browsers support image formats differently, especially formats such as HEIC and TIFF. Large images may also consume more device memory during processing. Some format features may not be preserved after conversion. For example, transparency may be lost when converting to JPG, and animated images may become static depending on the selected output format. These limitations need to be handled through clear prompts and error messages.

Detecting what powers a website looks simple: send a request, read the response, match fingerprints. In real environments it rarely stays that clean. False positives slip through, infrastructure hides behind CDNs, old scripts linger after migrations, and fingerprints keep evolving. Developers who treat fingerprinting as a basic utility end up acting on misleading data. This guide covers the mistakes engineers make detecting website technologies and how to avoid them. Modern detection workflows lean on ProjectDiscovery's libraries, which cut these problems through structured pattern matching and maintained datasets. External resources: github.com/projectdiscovery/wappalyzergo projectdiscovery.io If you're new to the space, start with technology fingerprinting for developers before these pitfalls. Mistake 1: Trusting a single detection signal Relying on one clue is the fastest way to get a wrong answer. A script file may linger after a framework migration, a header can be spoofed, and a cookie might belong to a third-party service. Correlate several signals instead: headers, cookies, HTML patterns, script paths, metadata. When multiple indicators point at the same technology, confidence goes up. ProjectDiscovery's libraries are built around that multi-signal approach. Mistake 2: Treating detection as a one-time task Stacks change constantly. Organizations migrate infrastructure, update frameworks, and swap platforms more often than developers expect. Scan once and trust it forever and you're working from stale data. Schedule periodic scans. Many teams wire detection into automation pipelines so infrastructure changes get captured on their own. To operationalize this, see detect website technologies programmatically in Go . Mistake 3: Ignoring reverse proxies and CDNs Modern architectures hide origin servers behind proxy layers. You might detect a CDN and miss what actually powers the app. Detecting a CDN doesn't make the origin invisible. It means you need to look fur
