India is home to about 60% of the world’s wild Asian elephants, and around 80% of the animals’ habitat lies outside protected areas, according to the Ministry of Environment, Forest, and Climate Change. That brings people and wildlife into close contact, and clashes can turn lethal: There have been some 3,000 human casualties in the…

I kept running eslint and thinking my codebase was fine — then someone opened a PR and the first comment was "this function needs JSDoc." The problem: linters check your syntax . Nobody checks whether your exported API is actually documented. Those are two very different things. So I built jsdocscan — a zero-dependency CLI that walks your JS/TS files and flags every exported function or class that is missing JSDoc, or has undocumented parameters. What it catches Errors — exported function or class with no /** … */ block at all: ✗ src/api.js:12 fetchUser missing JSDoc ✗ src/utils.js:34 formatDate missing JSDoc Warnings — JSDoc exists but a parameter has no @param tag: ! src/render.js:7 renderCard undocumented params: opts Exit codes are 0 (all clean), 1 (issues found), 2 (usage error) — pipe-friendly. How to use it # scan a directory npx jsdocscan src/ # Python version pip install jsdocscan jsdocscan src/ # skip @param checks — just verify JSDoc exists npx jsdocscan --no-params src/ # machine-readable output npx jsdocscan --json src/ | jq '.[].findings' # summary line only npx jsdocscan --quiet src/ # custom extensions npx jsdocscan --ext .js,.ts src/ What it skips (intentionally) Non-exported functions and internal helpers — these are implementation details Destructured params ({ a, b }) — too many valid @param opts patterns TypeScript type annotations on params — name: string is stripped, @param name is still required Zero dependencies No parsers, no AST, no require("typescript") . It uses a line-by-line scanner that: Detects export function/const/class patterns via regexes Walks backwards to find a preceding /** */ block Compares @param names in the JSDoc against the actual parameter list npx jsdocscan works with zero install time. pip install jsdocscan brings in nothing extra.

Having spent over 25 years in software development and managing countless Linux environments, I've accumulated a vast collection of custom bash scripts, containers, and CLI tools. Remembering their exact paths and managing them efficiently directly from the terminal is a common challenge. To solve this, I built mytuis . mytuis is a small, attractive terminal UI for managing a personal catalogue of applications. It is built with gum and plain bash, with persistent storage in a human-readable YAML file. GITHUB REPO : https://github.com/horaciod/mytuis Why mytuis? I wanted a tool that didn't require heavy dependencies or a complex setup, but still looked great and provided a smooth user experience. Here is what mytuis brings to the terminal: CRUD operations: You can create, read, update, and delete application entries from a single menu. Quick launch: Pick an app from the filterable list and it is launched immediately. It replaces the manager process via exec, meaning no extra shell window is left behind. Smart path handling: It accepts absolute paths (like /usr/bin/firefox), relative paths (./scripts/myscript.sh), tilde paths (~/bin/foo), or plain command names looked up in your $PATH (firefox). Persistent metadata: Every entry stores its name, description, absolute path, creation date, and last-used date. Friendly TUI: You get clear menus, color-coded messages, and clean borders, all powered by gum. Under the Hood: Plain Text and Standard Utils Simplicity and standard compliance were key goals. mytuis requires bash ≥ 4 and standard Unix utilities like awk, sed, grep, date, and tput. Your catalogue is stored at ~/.mytuis.yaml. Because it is a standard YAML file, it can be inspected, edited, or backed up with any text editor. It is also completely safe to sync with a dotfiles repository or version-control. To ensure data integrity, all file operations are performed atomically by rewriting the YAML file from scratch on every change, so there is no risk of leaving the fi

Whitespace problems are the ones you can't see until they bite. A pull request where half the "changes" are trailing-space diffs. A shell script that breaks in CI because someone's editor saved it CRLF. A .env with a UTF-8 BOM that makes the first variable name mysteriously not match. A file with no final newline that turns one-line changes into two-line diffs forever. None of it shows up on screen. All of it shows up in git blame . Today, catching this takes three or four tools stitched together — and I got tired of that, so I built wssweep : one zero-config command that finds all the common whitespace smells and, with --fix , cleans them in place. $ npx wssweep src/app.js (2) 14: trailing-whitespace trailing whitespace - missing-final-newline no newline at end of file config.yml (1) - mixed-eol mixed line endings (CRLF×3, LF×1) ✖ 3 whitespace issues in 2 files (mixed-eol=1, missing-final-newline=1, trailing-whitespace=1) $ npx wssweep --fix # clean them It checks seven things: trailing whitespace, mixed CRLF/LF line endings, lone CRs, a missing final newline, extra trailing blank lines, a UTF-8 BOM, and tabs mixed with spaces in one indent. Non-zero exit on findings, so it's a CI gate. pip install wssweep gets the same tool in Python — byte-for-byte identical output and fixes. Why not editorconfig-checker / pre-commit / prettier? Because each does part of it: editorconfig-checker reports — but you have to author an .editorconfig first, and it can't fix anything. pre-commit 's trailing-whitespace / end-of-file-fixer / mixed-line-ending hooks do fix, but only inside the pre-commit framework, and they're three separate hooks. Nobody runs them ad-hoc on a fresh checkout. prettier fixes whitespace only as a side effect of reformatting all your code, and won't touch files it can't parse. dos2unix does line endings and nothing else. wssweep is the one npx / pip command, no config and no framework, that does the whole set at once and drops into any CI regardless of toolch

We constantly hear that Ansible and Python are apparently the only ways to automate networks, today I even listen in a conversation "Python is the industry standard" probably I missed the RFC document or probably the guy was referring to a sales standard, but back to us what happens when the framework, the platform or the software we are using becomes heavier than the problem to solve? There is a moment where automation becomes necessary, not because we want to look modern, not because every task deserves a framework and not simply because adding automation automatically means we are doing things better. It becomes necessary because repeating the same command collection manually across many devices is slow, risky, boring and almost impossible to diff and validate properly especially under pressure. For this reason I built the Cisco Go Collector during a real migration activity with a very practical goal: collect configuration and command outputs from Cisco devices in an easily repeatable way, without forcing every colleague involved in the process to become developers or to install an automation stack just to run a super simple flow. The idea was simple: define the devices in a CSV which is the comfort zone for everyone define the commands in the same CSV file, super simple and organized to manage one row per device run a portable Go binary against that CSV file collect the outputs in organized text files archive the result as operational evidence that can be easily diff That is it! super lightweight to run no Python virtual environment no Ansible playbook structure no inventory hierarchy no framework onboarding no additional runtime or software on corporate managed workstations just a CSV file and a compiled binary The automation and AI trap when the solution is heavier than the problem to solve I love automation and I fully support AI if used the proper way, but we have to find a balance and recognize when to choose one tool over the other and specially one progra

ClickHouse HTTP API: A Complete Beginner's Guide Introduction When most people think about interacting with a database, they usually imagine connecting through a database client or application. However, ClickHouse also provides a simple and powerful HTTP API that allows you to query and manage your database using standard HTTP requests. The ClickHouse HTTP API provides a universal interface for communicating with your ClickHouse server. Since almost every programming language and automation tool supports HTTP, it becomes an excellent choice for integrations, monitoring, scripting, and lightweight applications. In this guide, you'll learn what the ClickHouse HTTP API is, why it's useful, and how to perform common database operations using simple HTTP requests. What Is the ClickHouse HTTP API? The ClickHouse HTTP API is a built-in interface that enables clients to communicate with a ClickHouse server using the HTTP protocol. Instead of connecting through the native TCP protocol, you simply send HTTP requests and receive responses in formats such as JSON, CSV, TSV, XML, or plain text. The HTTP interface is: Language agnostic Easy to integrate with web applications Firewall friendly Simple to test using tools like cURL, Postman, or a web browser Because of its simplicity, the HTTP API is widely used for automation, dashboards, data pipelines, and monitoring systems. Why Use the HTTP API? The ClickHouse HTTP API offers several advantages: No dedicated database driver is required. Works with virtually every programming language. Easy integration with REST-based applications. Supports multiple output formats. Ideal for automation and scripting. Perfect for cloud-native applications and microservices. Common Operations Using the HTTP API, you can: Execute SQL queries Insert data Create and modify tables Retrieve query results Export data in different formats Automate database operations Authentication Options ClickHouse supports multiple authentication methods when using th

Most AI coding tools assume you're sitting in front of a repo. There's a working directory, some source files, tests, maybe a CI pipeline. The AI reads your code, suggests changes, ru****ns tests. Great model — if you're a developer writing code on a Tuesday afternoon. Now picture the other scenario. It's 2am. PagerDuty fires. You SSH into a box you haven't touched in three months. Something is broken, you're not sure what, and the runbook was last updated by someone who left the company in 2022. You're not thinking about repos. You're thinking: what OS is this thing running? What just failed? Is it safe to restart that service or will I make it worse? These are two fundamentally different workflows. But almost every AI terminal tool I've seen is built for the first one. The 30 minutes nobody builds for There's a ton of tooling for the world before you log into the box: Prometheus, Grafana, PagerDuty, incident.io, runbooks, dashboards. All useful. No complaints. But there's this practical 30-minute window after you SSH in where you're basically doing archaeology with journalctl and grep. You check systemd. You look at disk. You read logs that were clearly written by someone who hated future-you. You copy-paste terminal output into Slack so your teammate can squint at it from a different timezone. This is where I think AI could actually help. Not by replacing Grafana. Not by building another dashboard. Just by being present in the shell while you're debugging. Please, for the love of uptime, don't replace my shell I've seen a few AI terminal projects that basically build an entire new terminal experience from scratch. New keybindings, new UI, new everything. Here's the thing: ops people have muscle memory. We have aliases we wrote in 2019 and forgot about. We have tmux configs we'd defend with our lives. We SSH through jump hosts with key forwarding chains that barely work but have worked for years so nobody touches them. If your AI tool requires me to abandon all of

I love Claude Code's subagents. But I kept noticing the same chore: every new project, I'd hand-write the same crew again — a builder, a reviewer, someone to keep the stack conventions straight. Good setups, but they lived in one repo and never got reused. So I built ccteams — a package manager for agent teams. One command drops a ready-made team of Claude Code subagents into your project. npm install -g ccteams ccteams use go-api // apply your favourite team That applies a Go builder + reviewer, tuned for net/http , to the current project. Switch when the work changes: ccteams use next-ts # Next.js App Router + TypeScript + Tailwind ccteams use generalist # scope -> design -> build -> QA -> ship, any stack Are you not sure which team you need? Don't worry, you can use /ccteams:choose-team and AI will choose the best team for you! /plugin marketplace add toffyui/ccteams /plugin install ccteams@ccteams /ccteams:choose-team I want to create a todo app. What's a "team"? A team is just a curated bundle of Claude Code subagents — each a markdown file with the usual name / description / tools frontmatter and a system prompt — plus an orchestration.md that gets merged into your project's CLAUDE.md . Nothing magic, nothing proprietary. It's the setup you'd build by hand, except already built and ready to reuse. ccteams ships with 8 teams: generalist — stack-agnostic, takes a feature scope → design → build → QA → ship next-ts — Next.js App Router + TypeScript + Tailwind frontend — framework-agnostic UI/UX and accessibility go-api — idiomatic Go HTTP APIs python-fastapi — FastAPI + Pydantic v2 rails — Ruby on Rails debug — reproduce → root-cause → fix → regression test research — compares options and recommends; writes no code What use actually does No black box. ccteams use <team> : Copies the team's agents into .claude/agents/ Writes .claude/active-team.md and adds an @.claude/active-team.md import to your CLAUDE.md Tracks everything in .claude/.ccteams-manifest.json so swi

You change one value in a JSON config, run git diff , and get a wall of red and green — because a formatter reflowed the file, or the serializer reordered the keys, or the indentation shifted by two spaces. The one thing you actually changed is buried in there somewhere. Good luck finding it in review. The problem is that git diff and diff work on lines . JSON isn't lines — it's a tree. So I built jdelta : it compares the data , ignores key order and whitespace entirely, and tells you exactly which values changed, addressed by path. Zero dependencies, no network. What it looks like $ jdelta config.before.json config.after.json Added (1) + features.darkMode true Changed (2) ~ auth.required true → false ~ server.port 8080 → 3000 +1 -0 ~2 auth.required flipped to false and you can see it instantly — no scrolling past 200 lines of reindented braces. Why not git diff / diff ? Because they diff text. Run a formatter, sort your keys, change two spaces of indent, and a line differ lights up the whole file while reporting zero semantic change. jdelta parses both sides and walks the trees: Object keys show as user.profile.age ; array elements as items[2].price . Odd keys fall back to quoted brackets ( ["order-id"] ). A key on only one side is added / removed ; a key on both with a different value is changed . A type change ( number → string , object → array ) is one changed entry tagged with the kinds — not a confusing add + remove. Reordered keys and whitespace produce nothing , because they aren't data changes. Great for reviewing config changes, API-response snapshots, tsconfig / settings.json , lockfile-adjacent files, and test fixtures. In scripts and CI jdelta a.json b.json --json # machine-readable: {added, removed, changed, summary} jdelta a.json b.json --quiet # just the +a -r ~c line jdelta a.json b.json --exit-code # exit 1 if they differ — gate a pipeline on it Install npx jdelta a.json b.json # Node build (npm) pip install jdelta # Python build — same behavior Tw
