Your docs pipeline, from the terminal PaperQuire v0.2.0 ships with a full command-line interface. Everything you can do in the desktop app — render, template, brand — now works from your terminal. This means you can automate document generation, integrate PaperQuire into CI/CD pipelines, and batch-process entire directories of Markdown without opening the GUI. Quick start If you installed via Homebrew, the paperquire command is already on your PATH: brew install --cask paperquire/paperquire/paperquire Verify with: paperquire version The simplest render is just: paperquire report.md This produces report.pdf in the same directory, using the default template. What you can do Render with options Apply templates, set metadata, control output: paperquire report.md -t corporate --title "Q2 Report" --author "Jane Doe" paperquire spec.md --page-size a4 --margins 0.75,0.75,0.75,0.75 --no-toc paperquire draft.md --watermark "DRAFT" -o drafts/draft.pdf All 22 flags from the desktop app's Document Setup panel are available. See the full list in the CLI Reference . Pipe through stdin/stdout PaperQuire works in Unix pipelines: cat notes.md | paperquire - --stdout > out.pdf Use - as the input file to read from stdin, and --stdout to write the PDF to stdout instead of a file. Batch render directories Render every Markdown file in a directory with one command: paperquire batch ./docs -o ./out paperquire batch ./project --glob "**/*.md" -t corporate paperquire batch ./docs --concurrency 8 --continue-on-error Use --dry-run to preview which files would be rendered without actually producing output. Manage templates List, inspect, create, and share templates: paperquire templates list paperquire templates show minimal-clean paperquire templates init my-template paperquire templates export corporate -o corporate.pqt paperquire templates import ./shared-template.pqt We also launched a community templates repo where you can browse all built-in templates and submit your own via pull request.

You exported a product CSV, edited it in Excel or Google Sheets, and uploaded it to Shopify. Shopify shows a generic error — or worse, it silently imports the wrong thing: a handle gets overwritten, a variant attaches to the wrong product, half your rows go missing. You find out days later from a customer. Shopify CSV Preflight Validator checks the file before you upload it. It runs locally on your machine, never touches your store, needs no API key, and returns three things: fixed_products.csv — a safe copy with the unambiguous, mechanical mistakes already corrected. errors.csv — a machine-readable list of every finding (row, rule, severity, suggested fix). report.md — a human-readable report you can read in 30 seconds. No login. No upload of your catalog to a third party. Just a file in, a verdict out. Why CSV imports fail (and why the error message doesn't help) Shopify's product CSV import is a two-stage process: it validates the file, then applies rows. A file can pass the upload dialog and still misbehave on apply. The most common ways merchants get burned: A spreadsheet adds a UTF-8 BOM to the first cell. The first header ( Title ) becomes invisible-garbage + Title , so Shopify can't find the title column. Header case / legacy names drift. title instead of Title , Handle instead of URL handle . Some get ignored, some get rejected. A variant row loses its parent handle. Shopify can't tell which product the variant belongs to. Two product rows share one handle. Shopify silently keeps one and overwrites/merges the other. Image alt text with no image URL, negative prices, compare-at prices below the real price — small data bugs that ship to your live storefront. These are not exotic. They're what happens every time a human edits a CSV in a spreadsheet. What the tool actually does — a real run Here is a messy export with several of the problems above. Running: csv-preflight check messy-product-import-sample.csv --out-dir ./out --lang en produces this report.md (ve

A few weeks back I shared some early Zen code examples. Since then, a lot has changed. We're now at v1.1.1 and the language actually has real tooling. What's new: Full CLI with package management zen publish - publish packages directly from CLI zen install - install packages from the registry zen list - browse all published packages with pagination Language improvements Struct support with literals and returns Regex with POSIX ERE ( matchRegex ) File I/O with binary support FFI bindings to C functions 162 stdlib functions across math, strings, fs, os, http, crypto, path utilities Package Registry (v1.0.0) JWT-based authentication GitHub-hosted packages Support for both runnable apps and libraries Semantic versioning The reactive variables concept from the first post is still there (that was my favorite feature), and now you can actually write real programs and share them with the community. Full docs: https://jishith-dev.github.io/zen-doc/site/ Install: curl -fsSL https://raw.githubusercontent.com/jishith-dev/Zen/main/install.sh | bash Next up: HTTP server APIs, better imports, and whatever the community asks for.

I'm building TTT -- a terminal text editor and IDE written in Go. Single binary, zero config, runs anywhere. Think VS Code but in your terminal. It has syntax highlighting, LSP integration, a plugin system, an integrated terminal, git integration, etc... The source is on GitHub and I develop it with Claude Code as my pair programmer. This is the story of how a frustrating limitation turned into something genuinely useful: a built-in scripted interaction system that lets AI agents (or anyone) drive the editor like Playwright drives a browser. The problem I was deep in revamping the widget system and building out a Lua plugin API. Phases of work stacking up -- widget rendering, panel support, tree views, input fields, command registration, keybinding hooks. The kind of work where you need to see what's happening. Click a tree node, check if it expands. Open a panel, verify focus moves correctly. Run a plugin, confirm the dialog appears. Here's the thing: Claude Code can run shell commands and read files. It cannot interact with a live TUI session. The editor launches, takes over the terminal, and that's it -- Claude is blind. Step 1: tui-use (what we had) The project already had functional tests using tui-use , a JavaScript library that drives a real terminal binary. It can type, press keys, wait for text to appear, and take snapshots: const tui = await start ( " bin/ttt " , [ " test-file.go " ]); await tui . waitFor ( " test-file.go " ); await tui . exec ( " editor.joinLines " ); const screen = await tui . snapshot (); expect ( screen ). toContain ( " joined line " ); This works. But it's slow -- each test spawns the binary, waits for screen renders, polls with timeouts, and parses terminal escape codes. And critically, it can't click . Mouse events aren't supported. For a widget system with tree views, buttons, and split panels, that's a dealbreaker. Step 2: Debug commands (the workaround) So we added a Debug: Simulate Click command to the editor itself. Open the co

The Promise: A Private, Voice-Activated Shell The dream of a voice-activated command line is compelling: speak a command, see it executed. But for many developers, piping terminal input through a cloud-based API is a non-starter. This is the promise of a project like karolswdev/HoldSpeak , a cross-platform tool for local voice typing. Could it be the core of a truly local-first, push-to-talk shell assistant? I paired it with Ollama and a local llama3.2 model to find out. The goal was simple: hold a key, speak a command like "list files by size," release the key, and have the correct shell command appear, gated by a final confirmation prompt. This project turned out to be a tale of two stacks: one for voice that was surprisingly clean, and one for language that revealed the sharp edges of the local-first promise. Building the Demo To test this idea, I built a small Python script to tie these components together. You can find the complete code for this experiment, including the prompt engineering, in my demo project on GitHub: voice-activated-shell-demo . Setup Instructions Recreating this local-first voice assistant involves a few distinct steps: Install HoldSpeak from Source : Since we need to use it as a library, clone the repository and install it in editable mode. git clone https://github.com/karolswdev/HoldSpeak.git cd HoldSpeak pip3 install -e . Install and Run Ollama : Use Homebrew (on macOS) to install the Ollama CLI, then start the server. brew install ollama ollama serve Pull a Local LLM : In a separate terminal, pull a small, capable model. I used llama3.2 . ollama pull llama3.2 Grant Permissions (macOS) : To allow the hotkey listener to work, your terminal application (e.g., iTerm, Terminal.app) must be given Accessibility permissions in System Settings > Privacy & Security > Accessibility . Run the Demo Script : With the setup complete, you can run the final Python script that integrates all these components. Finding the Seams in HoldSpeak HoldSpeak pres

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
