"This is the sixth post in my series on Emacs completion.... This one coins a term for a special case, Incremental Suggesting Read (ISR), where the candidate set produced by incrementally typed input is a suggestion, rather than a literal completion of that input. The ability to generate inferred matches in addition to literal matches vastly expands the scope of what a 'completion' system can do. Two conceptual sources supply the suggestions: 1) semantic retrieval and 2) generative synthesis. This post is more speculative than useful, so carry that pinch of salt with you as you watch the video or read this post." submitted by /u/misterchiply [link] [留言]

In the face of widespread backlash to the AI data center buildout throughout the US, Google is touting its efforts to minimize the environmental impact by actually increasing water for local communities. The company laid out five commitments around water use in a new blog post published Wednesday, including a goal to replenish more water […]

After migrating Spark pipelines to Azure Kubernetes Service, two infrastructure settings interacted destructively: spark.kubernetes.local.dirs.tmpfs=true backed shuffle spill with RAM instead of disk, and a hard podAffinity rule forced all executors onto one node. Together, they caused repeated OOM kills invisible to standard diagnostics. By Pranav Bhasker

We run Quackr, a virtual phone number platform that lets developers and individuals receive SMS verifications without exposing a real number. We just published our first inventory transparency report and the data was surprising enough that we thought the dev community would find it useful. The Numbers Right now, 97.6% of our entire virtual phone number inventory is actively rented. 66,214 out of 67,815 numbers assigned and in use across 15+ countries. Over 1,000 numbers available at any given moment but they move fast. That utilisation rate tells you something about how the market has shifted. Virtual numbers are no longer a niche throwaway tool. Developers, businesses, and privacy-conscious users are holding them long term. What Developers Actually Use Virtual Numbers For The obvious use case is SMS verification during testing. Spin up a number, verify an account in staging, move on. But that is not what drives the bulk of demand on our platform. The real volume comes from: Multi-account management — developers and businesses running multiple instances of platforms that require unique phone verification per account. Privacy layers in production apps — applications that need to verify users without collecting their real numbers. A virtual number sits between the user and the platform. Automated verification pipelines — this is where our API and MCP Server come in. If you need to provision numbers programmatically and retrieve OTPs without manual intervention, this is the use case we built for. Geographic flexibility — needing a UK number from Australia, a US number from Ukraine, or any combination that your real SIM cannot provide. The OTP Blocking Problem Something worth knowing if you are building anything that involves SMS verification: platform-level VoIP blocking has become significantly more aggressive over the past two years. WhatsApp, Telegram, Google, and TikTok all run detection on incoming verification requests. A VoIP number gets flagged and the OTP simp

Most API teams treat the contract as an afterthought: write code, generate a spec, then watch the two drift apart. Git-native API design reverses that flow. You treat the API contract as source code, version it in Git, and review every change the same way you review application logic. Try Apidog today This guide focuses on implementation discipline, not a single tool. You’ll design contracts in branches, review them in pull requests, and turn a committed spec into mocks, tests, and docs. The goal is simple: your Git history should also be your API history. If you already know what Spec-First tooling looks like and want the product walkthrough, read the companion piece on the git-native API workflow . This article stays focused on practice. What “git-native” means for API work Git-native means your API definition lives in your repository as a plain text file. Not in a proprietary cloud database. Not behind a vendor login. A .yaml or .json file sits next to your code and is tracked by the same version control system your team already uses. In many cloud-locked API design tools, the contract lives in the vendor’s backend. You edit through a web UI, and your repository only contains an export. That export can become stale, and your Git history no longer explains how the API evolved. The git-native model inverts that relationship: The file in main is the contract. Any GUI is a view onto that file. Branches, commits, pull requests, blame, and rollback all apply to your API surface. Mocks, docs, tests, and generated clients derive from the committed spec. A git-native setup has three core properties: The spec is a text file in the repo. Changes flow through normal Git operations: branch, commit, PR, merge. Downstream artifacts derive from the committed file, not from a separate database. Why design and develop APIs in Git You already trust Git with your code. Your API contract deserves the same treatment. 1. History When someone asks, “When did we add the cursor pagination

TL;DR Day 2 of AI Native DevCon shifted from agent capability to operating discipline. The strongest sessions focused on how teams can run AI-native delivery with clearer context pipelines, measurable agent behavior, safer execution boundaries, and better organizational ownership. The scale showed up in the numbers too. Across the two days, DevCon brought together 650+ in-person registrations, around 2,000 online registrations, and a packed mix of sessions, workshops, hallway conversations, and practical lessons. Day 2 leaned into workshops. That shift mattered because the second day was less about proving agents can do useful work and more about showing how teams can make that work repeatable. Hey there, welcome back. Rohan Sharma here again continuing the devcon series. Day 1 gave us the framing, including Guy Podjarny ’s core point that skills should be treated like real software assets. Day 2 picked up from there and moved into the operating details. Once agents are inside daily engineering work, platform and product teams need to decide what changes first, who owns those changes, and how the results are measured. Talks that shaped Day 2 Harness engineering beyond code Marc Sloan from Tessl focused on the next gap many teams are hitting. Code context is increasingly structured, but product and design context still lives in external systems such as Figma, Notion, and Linear. Pulling that context live can reduce staleness, but it introduces drift in evals, versioning, and reproducibility. The practical lesson was to stop treating external product and design context as random reference material. Teams need a defined layer between the repository and those external systems, with clear versioning so evaluations can be replayed against known context snapshots. Without that, agents can produce work that looks technically correct while missing the product constraint that actually mattered. That is a very expensive kind of almost-right.

If you've ever built a REST API with Express, you've probably felt it. Middleware registration, type definitions, body parser setup, connecting Joi or Zod... the structure is simple, but the boilerplate is excessive. When I first saw Hono, I was skeptical. "Another Express clone," I thought. That changed when I actually ran it. Bottom line: Hono v4 is more than just lightweight and fast. TypeScript type inference flows naturally all the way to route handlers. Zod validation connects via a single official package. On Bun, response times are noticeably faster than Express. Everything in this post is based on what I ran in a sandbox in June 2026. Why Hono — Compared to Express and Fastify Understanding where Hono fits means answering three questions. Bundle size : Hono v4 core is about 12KB. Express is 58KB, Fastify is 77KB. The gap might not sound dramatic, but in edge environments like Cloudflare Workers or Deno Deploy, bundle size directly affects cold start time. Edge functions sometimes initialize a new runtime per request — smaller means faster first response. Runtime compatibility : Express is Node.js-only. Fastify targets Node.js by default. Hono was designed from the start to "run anywhere." The same code deploys to Bun, Deno, Cloudflare Workers, Node.js, and AWS Lambda Edge. TypeScript support : Express requires @types/express as a separate install, and properties added to req via middleware don't get type inference. Hono is written in TypeScript from the ground up, and the Hono<{ Bindings: Env; Variables: Variables }> generic gives you type-safe access to environment variables and middleware state. I'm not saying Hono is the right choice for every situation. If your team is deeply invested in Express, or you need a mature plugin ecosystem, there's no compelling reason to switch. But if edge deployment is the goal, or you want type safety from day one, Hono is the most convincing TypeScript API framework right now. Installation and First Server — Response in

Node.js will change its release schedule starting with version 27 in October 2026, moving from two major releases per year to one. All releases will become Long-Term Support (LTS), removing the distinction between odd and even versions. An Alpha channel for early testing will also be introduced. This decision addresses maintenance challenges and aims to align with user needs. By Daniel Curtis

Introduction: The Question of Relevance Imagine you’re a college student, fresh off mastering pandas , and you’re eyeing the freelancing market for data cleaning and automation gigs. You’ve heard of openpyxl , but as you dig deeper, you hit a wall: every resource seems to peg it as a relic for handling 2010 Excel sheets . That’s it. No modern use cases, no integration with cutting-edge tools, just a dusty library stuck in the past. So, you pause. Is openpyxl still relevant in 2023, or is it a dead end for someone trying to build a competitive freelancing portfolio? This dilemma isn’t just about openpyxl—it’s about the mechanism of perception in tech. When a tool is associated with outdated formats, its capabilities are often misinterpreted or overlooked . Openpyxl’s documentation and community discourse rarely highlight its modern applications, leaving newcomers like you to assume it’s obsolete. But here’s the catch: openpyxl isn’t just a 2010 Excel handler. It’s a low-level Excel manipulator that, when paired with libraries like pandas and numpy, can handle complex tasks that these libraries alone can’t. The problem isn’t openpyxl’s functionality—it’s the information gap between its perceived and actual utility. The stakes are clear: if you dismiss openpyxl as outdated, you risk missing out on a tool that could complement your pandas and numpy skills , making your freelancing services more efficient and versatile. But if you invest time in it without understanding its modern applications, you might waste effort on a tool that doesn’t align with current demands. The question isn’t whether openpyxl is relevant—it’s whether you’re looking at it through the right lens. In this investigation, we’ll dissect openpyxl’s role in 2023 freelancing, addressing its perceived limitations and uncovering its hidden strengths. By the end, you’ll have a clear rule for deciding whether to include it in your toolkit: If your freelancing gigs involve Excel-specific tasks that pandas ca

I run multiple Claude Code sessions all day — one per feature, one per service, sometimes five at once. Every session was asking me for permission in its own terminal. I'd miss requests buried in a background tab. I'd switch windows mid-thought just to approve a git status . I'd lose context constantly. And there was no single place to see what Claude was doing across all of them. So I built Gatekeeper — a TUI daemon that intercepts every Claude Code tool call and routes it to one unified approval dashboard. The dashboard Three panes, one terminal: Left — all active Claude sessions, with status badges: [auto] means auto-approve is on, [linked] means it's wired to a terminal window Middle — pending permission requests with an age timer so you know what's been waiting longest Right — full request detail, danger warnings, and the numbered approval menu Every Claude Code tool call — Bash , Edit , Write , Agent — passes through a PreToolUse hook before executing. The hook connects to Gatekeeper's Unix socket, sends the request, and blocks. Gatekeeper shows it in the UI. When you decide, the answer travels back and Claude proceeds or stops. Approving requests The menu in the right pane mirrors Claude Code's own style: 1 Allow once 2 Always allow 3 Deny ↑ / ↓ moves the cursor, Enter confirms. Or just press 1 , 2 , 3 directly. A and D are quick shortcuts for allow/deny. Option 2 — always allow — is where it gets useful. Choosing it saves a persistent rule so the same request never surfaces again: Bash → saves the command pattern (e.g. npm run * ) to config Edit / Write → saves the directory to an allowlist Agent → enables auto-approve for that session The rule is written both to Gatekeeper's own config and to Claude Code's settings.json allowlist — so Claude Code itself won't prompt for it either. Auto-approve sessions Press A in the Sessions pane to mark a session as trusted. It shows [auto] — routine tool calls pass silently without appearing in the queue. But some things

Hand the same paired before/after dataset (n = 25) to ChatGPT five times. Same prompt: "These are the same subjects measured before and after an intervention. Did their scores change significantly?" Four of the five runs return p = 0.009 from a paired t-test. The fifth run does a Shapiro–Wilk normality check on the differences first, decides they're non-normal, switches to a Wilcoxon signed-rank test, and reports p = 0.000018 . All five reach the same conclusion (significant). But notice what happened: only one run out of five thought to check an assumption you'd want it to check. The other four skipped it. The choice of method — and the test statistic, and the p-value — depended on whether the LLM happened to run an assumption check that time. On borderline data, this is the difference between reject and don't reject. If you're using LLMs for exploratory data analysis on a weekend project, you might shrug. If you're using them for anything that gets cited, gets submitted to a regulator, or gets handed to a clinician, this is a problem. It's a known problem — Cui & Alexander (2026) documented exactly this kind of method-divergence empirically; AIRepr (Zeng et al., 2025) shows the same thing across reproducibility metrics. The current answer in the literature is to constrain the agent so its execution is replayable. But replayability fixes "did we run the same code." It doesn't fix "did we run the right analysis." I've spent the last two months building a different fix. The more interesting half is the architecture. Let me walk through it. The real problem isn't temperature The first reflex is "set temperature=0 ." It's not enough. temperature=0 doesn't make a tool-using agent deterministic across runs. Three reasons: Inference isn't bitwise deterministic, even at temperature=0. Production LLM serving batches requests dynamically, and the attention kernels aren't batch-invariant — so the same input produces different output tokens depending on what other requests it

Hello Dev Community! 👋 It is officially Day 12 of my journey to master the MERN stack! Today, I wrapped up Lecture 3 of Apna College's JavaScript playlist with Shradha Didi, focusing on a fundamental data type we use every day: Strings . Before today, I thought strings were just plain text wrapped in quotes. Today, I learned how much power JavaScript gives us to manipulate, slice, and dynamically format text. 🧠 Key Learnings From JS Lecture 3 (Strings) I explored how JavaScript handles text strings and the built-in properties and methods that make text manipulation effortless: 1. Template Literals (The Ultimate Game Changer) Shradha Didi introduced Template Literals , which use backticks ( ` ) instead of standard quotes. This allows us to perform String Interpolation —embedding variables directly inside a string using ${variable} . It makes code look clean and professional: javascript let obj = { item: "pen", price: 10 }; // Old way: console.log("The cost of", obj.item, "is", obj.price, "rupees."); // Modern way: console.log(`The cost of ${obj.item} is ${obj.price} rupees.`);
