Europeans are baking under their second heat wave of the summer.

It’s been hard to look away from headlines about the European heat wave this week. Temperatures are breaking records across the continent, and the weather is threatening lives, shutting down schools, and in one particularly ironic case, forcing the cancellation of a London Climate Action Week event about extreme heat. As the summer ramps up…

Dai metadati in una lingua a 20 localizzazioni senza impazzire tra click e schermate: un flusso pratico per indie e piccoli team. Localizzare un’app non significa solo tradurre le stringhe dell’interfaccia. Una buona parte dell’acquisizione organica passa dai metadati su App Store Connect : titolo, sottotitolo, descrizione e keyword. Il problema è che, quando provi a farlo “a mano” dal pannello web, diventa subito un lavoro di pura resistenza: apri la scheda, cambi lingua, compili i campi, salvi, ripeti. Ora moltiplica per 10–20 lingue. Per molti indie (e in generale per chi ha poco tempo e zero voglia di click ripetitivi) il punto di svolta è usare ASC CLI per rendere questa attività automatizzabile, ripetibile e verificabile . Perché la localizzazione dei metadati è un caso d’uso perfetto per una CLI Dal punto di vista del flusso di lavoro, i metadati App Store hanno tre caratteristiche che li rendono ideali per l’automazione: Sono campi strutturati (title, subtitle, description, keywords): non stai “inventando” contenuti ogni volta, stai trasformando contenuti. Sono ripetitivi per lingua : la sequenza di operazioni è identica, cambia solo la locale. Sono tanti : più lingue aggiungi, più l’approccio manuale scala male (tempo, errori, incoerenze). Con una CLI, invece, il lavoro si sposta dal “fare cose” al definire un processo : prendi i metadati di partenza, generi le varianti linguistiche, applichi l’update in batch. Cosa conviene localizzare (e cosa no) In genere ha senso includere in un passaggio di localizzazione “massiva”: App name / title (attenzione ai limiti e ai trademark) Subtitle (spesso è la parte più ASO-oriented) Description (qui conta più la leggibilità che la traduzione letterale) Keywords (campo delicato: va adattato, non tradotto alla cieca) Al contrario, è meglio trattare con più cautela: Claim e frasi marketing molto creative : in alcune lingue risultano innaturali se tradotte letteralmente Keyword strategy : la ricerca utenti cambia per mercat

While there was probably a moment when Slate’s leadership had to green-light the switch from one battery type to another, the momentum toward that decision had been building for years.

A couple weeks ago I posted about ImageX - a dumb little CLI that lets you edit images without googling "resize image online" for the hundredth time. If you haven't seen it, the tldr is: pip install imagex && imagex , a menu pops up, pick what you want, done. No flags to memorize, no syntax to look up - just arrow keys and enter. Everything runs locally on your machine - no uploads, no server ever sees your images, no browser,no ads. Honestly? Didn't expect much. But: 10 stars on GitHub 1 contributor already dropped a PR (Flip feature - thanks! :) A bunch of feature requests in issues So I kept building. What's new in v0.3.0 Three features, one fix: Grayscale / B&W - luminosity conversion or threshold-based true black & white. Slider for the threshold so you can dial in exactly how much black you want. Invert Colors - instant negative. Handles RGBA without destroying alpha. Flip - mirror horizontally, vertically, or both. (PR from a contributor!) Plus: version check on startup (tells you when to upgrade), and all operations now preserve EXIF/ICC metadata instead of silently dropping it. Yeah, that was a bug. Fixed. The code is still stupid simple NAME = " Invert Colors " DESCRIPTION = " Invert image colors (negative effect) " def run ( file , output_path , args ): img = Image . open ( file ) # ... invert logic ... img . save ( output_path ) return True Links GitHub: github.com/kushal1o1/ImageX PyPI: pip install -U imagex PRs welcome. You could write a feature in the time it took to read this.

Europe is in the middle of a record-breaking heat wave, and the grid is being pushed to its limits as people turn to fans and air-conditioning to try to stay cool. Some power plants won’t be online to help handle the load. On June 23, France saw its hottest day since record-keeping began in 1947.…

As record-breaking heat crushes Europe, organizers are moving events online to avoid exposing people to dangerously high temperatures.

Introduction When a query runs in ClickHouse®, the database does much more than simply read data and return results. Before execution begins, ClickHouse® parses the SQL statement, analyzes it, applies optimizations, and builds an execution plan that determines the most efficient way to process the query. Understanding query execution plans is one of the most valuable skills for anyone working with ClickHouse®. They provide visibility into how queries are executed, helping you identify bottlenecks, validate optimization efforts, and troubleshoot performance issues. In this article, we'll explore how ClickHouse® generates execution plans, the different EXPLAIN modes, and how to interpret them for better query optimization. Why Query Execution Plans Matter A SQL query defines what data you want, but it doesn't explain how the database retrieves it. Consider the following query: SELECT country , count () FROM events GROUP BY country ; Although the query looks simple, ClickHouse® must determine: Which data parts to read Whether primary indexes can reduce the scan If data skipping indexes can be used How aggregation should be performed Whether parallel execution is possible How intermediate results should be merged A query execution plan provides answers to these questions, making it an essential tool for performance tuning. The ClickHouse Query Lifecycle Every query passes through several stages before producing results. The lifecycle typically looks like this: SQL Query │ ▼ Parser │ ▼ Analyzer │ ▼ Optimizer │ ▼ Query Plan │ ▼ Execution Pipeline │ ▼ Results Each stage plays an important role: Parser validates SQL syntax. Analyzer resolves tables, columns, and expressions. Optimizer applies query optimizations. Query Plan determines the logical execution steps. Pipeline distributes work across multiple threads. Execution processes the data and returns the results. Understanding this workflow makes execution plans much easier to interpret. Introducing the EXPLAIN Statement

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
