Your mobile release setup belongs in Terraform: Expo EAS + App Store Connect

If you ship a React Native / Expo app to the App Store, you know the ritual. Open the Apple Developer portal, create a bundle identifier, tick the capability checkboxes, generate a provisioning profile, pick the right certificate. Then hop over to the Expo dashboard, create the EAS app, wire up credentials, add your environment variables one screen at a time. It works, until you have to do it again for a second app, or a second environment, or a teammate needs to know why a capability is enabled. None of it is written down. It drifts. And the usual mobile tooling doesn't help much here: fastlane and the EAS CLI are great, but they're imperative — scripts that do things — not a declarative description of what your release setup should be . That's the gap these two providers fill: elevenode/appstore — App Store Connect: bundle identifiers, provisioning profiles, certificates. elevenode/expo — Expo Application Services (EAS): apps, credentials, environment variables, update channels. Both are open source (Apache 2.0) and published on the Terraform Registry. Let's use them together to describe a mobile app's release setup as code. What you'll need Terraform (or OpenTofu) An App Store Connect API key (Users and Access → Integrations → App Store Connect API): the key, its key ID, and your issuer ID An Expo access token (expo.dev → account settings → Access Tokens) and your Expo account name Export the credentials as environment variables so nothing sensitive lands in your config: export APPSTORE_KEY = " $( cat AuthKey_XXXX.p8 ) " export APPSTORE_KEY_ID = "XXXXXXXXXX" export APPSTORE_KEY_ISSUER_ID = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" export EXPO_TOKEN = "your-expo-access-token" export EXPO_ACCOUNT_NAME = "your-account-name" Wiring up both providers terraform { required_providers { appstore = { source = "elevenode/appstore" } expo = { source = "elevenode/expo" } } } # Reads APPSTORE_KEY / APPSTORE_KEY_ID / APPSTORE_KEY_ISSUER_ID from the env. provider "appstore" {} # Re

GitLab CI "Cannot connect to unix:///var/run/docker.sock"

The fast fix If your GitLab CI job fails with Cannot connect to the Docker daemon at unix:///var/run/docker.sock , your docker client is looking for a local socket that does not exist inside the job container, because DOCKER_HOST is not set. Point the client at the docker:dind service over TCP and the error goes away: build : image : docker:28.3 services : - name : docker:28.3-dind alias : docker variables : DOCKER_HOST : tcp://docker:2376 DOCKER_TLS_CERTDIR : " /certs" DOCKER_CERT_PATH : " /certs/client" DOCKER_TLS_VERIFY : " 1" script : - docker info - docker build -t my-app . That is the whole fix for the common case. The rest of this page explains why the socket variant of the error is different from the tcp://docker:2375 variant, and covers the two other setups (socket-mounted runners and the Kubernetes executor) where the same message shows up for a different reason. Why you get the unix socket variant specifically This error is not the same as Cannot connect to the Docker daemon at tcp://docker:2375 . The address in the message tells you exactly what the client tried: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? When DOCKER_HOST is empty, the Docker CLI falls back to its compiled-in default, the local unix socket at /var/run/docker.sock . Inside a GitLab CI job that uses the docker executor, that socket file simply is not there. The daemon runs in a separate docker:dind service container, not in your job container, so there is nothing listening on the local socket. The client connects, finds no socket, and prints the message above. The tcp://docker:2375 form is the opposite problem: DOCKER_HOST is set correctly but the dind service is not reachable (missing service, no privileged mode, or a TLS mismatch). If you are seeing that address instead, read the companion write-up on the tcp://docker:2375 form of this error , which walks the service and privileged-mode causes in detail. This page is about the case w

Coolify: The Complete Manual Setup Guide (For When the Auto-Install Script Won't Cut It)

Coolify's one-line install script is great — until it isn't. Right now it officially supports Ubuntu 20.04, 22.04, and 24.04 LTS. If you're running anything newer (Ubuntu's already on 26.04 LTS), the script won't work and you're left doing it manually. This is that manual walkthrough — set up in the order that fits a security-first VPS workflow rather than the order Coolify's own docs use. If you've been following along with the Ansible playbooks from earlier in this series, this picks up right where that left off. Minimum Hardware Requirements CPU: 2 cores Memory: 2 GB RAM Storage: 30 GB free Coolify can technically run below this, but it's not recommended. Prerequisites Before touching Coolify itself, you'll need: SSH access to your VPS CURL installed Docker Engine installed If you're reconnecting to a server you've rebuilt or re-provisioned, clear the old fingerprint first: ssh-keygen -f '/home/your-path/.ssh/known_hosts' -R 'your-vps-ip' Installing SSH If you followed the earlier videos in this series, OpenSSH is already installed. If not: sudo apt update && sudo apt install -y openssh-server Confirm it's running and check which port it's listening on (you should have already changed this from the default 22 — see the VPS security video): sudo systemctl status ssh sudo ss -tulpn | grep ssh Installing CURL sudo apt update && sudo apt install -y curl curl --version curl and ca-certificates also get installed as part of the apt-update Ansible playbook below, so this may already be handled. Running the First Ansible Playbook Connect Ansible to the VPS: ANSIBLE_HOST_KEY_CHECKING = FALSE ansible -i ./inventory/hosts vpsDemo -m ping --user root --ask-pass Then run the update playbook: ansible-playbook ./playbooks/apt-update.yml --user root -e "ansible_port=22" --ask-pass --ask-become-pass -i ./inventory/hosts If you haven't set up the Ansible inventory and playbooks from the earlier videos, do that first — this guide assumes they're already in place.

NocoBase and the mystery of the shifted timestamps: MySQL vs PostgreSQL, measured

There's a class of bug reports that keeps coming back in the NocoBase community, especially in the Chinese-language forum: "all my times are off by 8 hours" or "dates show up as the day before." China is UTC+8, so the shift is 8 hours there. I run my instances at UTC+9, and sure enough — my shift is 9 hours. Whatever your offset is, that's the size of your shift. That pattern is a strong hint that this isn't random corruption. It's a mechanism. I set up NocoBase 2.x against both PostgreSQL and MySQL and measured what actually gets stored and how it gets reinterpreted, until the mystery had a concrete answer. Test setup: NocoBase 2.0.51 and 2.1.23 (official Docker images) × PostgreSQL 16 and MySQL 8.4. All data written and read through the REST API, with the server timezone controlled via the container's TZ environment variable. I'm deliberately ignoring the browser-side rendering here — this is about what the server stores and how it interprets it. Background: 2.x has four datetime field types NocoBase 2.x collections offer four datetime-ish field types ( official list — though several of the per-type detail pages still say "To be added", which is exactly why I measured instead): Type What it's for Datetime (with time zone) Absolute instants — event start times, logs Datetime (without time zone) Wall-clock times you want preserved as-is Date only Birthdays, due dates, anniversaries Unix timestamp System integration Measurement 1: what each type actually stores I imported "2026-07-12 09:00" via xlsx and looked at the raw values in each database (identical on 2.0.51 and 2.1.23): Field type PostgreSQL MySQL Datetime (with TZ) timestamptz → 2026-07-12 09:00:00+09 ( an absolute instant, offset included ) DATETIME → 2026-07-12 09:00:00 ( wall clock only — no offset information ) Datetime (without TZ) timestamp → 09:00:00 DATETIME → 09:00:00 Date only date → 2026-07-12 date → 2026-07-12 The first row is the whole story. The same field type — "Datetime (with time zone)" — i

I built SwiftNotch: a productivity dashboard for the MacBook notch

The notch on a MacBook is strange real estate. It is always there. It sits at the top of the screen, close to the menu bar, close to system controls, close to whatever you are doing. But most of the time it is treated like a cutout to design around instead of a place software can use. That felt like a missed opportunity. So I built SwiftNotch , a macOS menu bar app that turns the notch area into an expandable productivity dashboard. Hover near the notch or press Option + Space , and the quiet black shape becomes a small command center for widgets, files, media, shortcuts, developer tools, and window actions. Website: swiftnotch.xyz Demo video: Launch note: SwiftNotch 1.x is free during beta . I want early Mac users to try the full experience, share feedback, and help shape the app before SwiftNotch 2.0 introduces paid plans. The idea I did not want to build another large dashboard that asks you to leave your current app. The goal was the opposite: make useful tools available in the smallest possible space, without breaking flow. The notch is perfect for this because it already behaves like a visual anchor. You know where it is without thinking. If it can expand only when needed, it becomes a temporary interface layer instead of another permanent panel. SwiftNotch starts collapsed. When activated, it opens into a compact dashboard with the widgets and actions you choose. What SwiftNotch does The current app includes 31 built-in widgets across productivity, system utilities, media, automation, and developer workflows. Some examples: Media Control for Spotify, Apple Music, VLC, YouTube, and browser players Shelf for drag-and-drop file staging, quick sharing, paths, iCloud actions, and zip workflows Clipboard History for snippets, links, and quick paste Calendar Events , Reminders , Notes , Weather , World Clock , and Pomodoro Quick Toggles for Wi-Fi, Bluetooth, Dark Mode, and volume Window Snapping with layouts for halves, thirds, quarters, and custom grids Developer H

What 18 months building a self-hosted media server taught me about playback

Project: https://quven.tv/ Security model: https://quven.tv/security/ For the last 18 months, I have been building Quven, a self-hosted media server for personal movie, TV, and documentary libraries. I started with a seemingly simple goal: let people keep their media on their own hardware while giving them a polished client experience. Playback quickly became the hardest part. A media server does not simply send a video file to a screen. It has to understand the source, the client, the network, and the user's choices, then select a playback path without making any of that complexity feel visible. These are some of the lessons I learned. 1. "Can this file play?" is the wrong question The real question is whether a particular client can play a particular combination of: container; video codec and profile; audio codec and channel layout; subtitle format; resolution, bitrate, and frame rate; HDR format; network conditions. A client might support the video codec but not the audio track. A browser might decode the video but require a different container. Enabling an image-based subtitle can turn an otherwise direct-playable file into a video transcode. Playback compatibility is therefore not a boolean property of a file. It is a negotiation between the source and the active client. 2. Direct play should be the preferred outcome, not a promise Direct play preserves the original file and avoids unnecessary server work. When the client supports the selected combination, it is usually the best path. But forcing direct play at all costs produces a worse experience. A high-bitrate file may technically be supported while still exceeding the available connection. A selected subtitle might require burning into the video. A television may accept a container while rejecting one of its audio formats. The practical hierarchy I settled on is: Direct play when the complete source is compatible. Remux when the streams are compatible but the container is not. Transcode only what must chan

Catch the dangerous Postgres migration at the CI step

-- looks routine in review, locks your table in production: CREATE INDEX idx_orders_customer ON orders ( customer_id ); ALTER TABLE users ALTER COLUMN email SET NOT NULL ; Both of those statements hold a lock that blocks traffic while they scan or build against the table. On a small table you never notice. On a busy production table it is downtime, and a diff review does not catch it because the SQL looks fine. pg-migration-guard is a free tool that reads the migration and flags these before they reach production: $ pg-migration-guard V42__orders.sql WARN IDX01 CREATE INDEX without CONCURRENTLY [becomes a blocker on a large or busy table] Why: Plain CREATE INDEX takes a lock that blocks all writes until the build finishes. Safe: CREATE INDEX CONCURRENTLY idx ON tbl (col); -- outside a transaction WARN NN01 SET NOT NULL scans the whole table under ACCESS EXCLUSIVE Safe: ADD CONSTRAINT c CHECK (col IS NOT NULL) NOT VALID; VALIDATE CONSTRAINT c; then SET NOT NULL; Summary: 0 blocker, 2 warn, 0 advisory Why migrations bite Whether a Postgres migration is safe has almost nothing to do with intent and everything to do with locks. A migration is dangerous when it holds a strong lock while it scans or rewrites a large table. ACCESS EXCLUSIVE blocks reads and writes; SHARE blocks writes. The change that reads fine in review is the one that quietly takes that lock. Put it in CI The most useful place for this is the pull request, so a risky migration fails the build before anyone merges it. There is a GitHub Action: name : migration-guard on : pull_request : paths : [ " db/migration/**.sql" ] jobs : guard : runs-on : ubuntu-latest steps : - uses : actions/checkout@v4 - uses : actions/setup-python@v5 with : python-version : " 3.x" - uses : technical-turtle/pg-migration-guard@v1 with : path : db/migration fail-on : blocker Each finding shows up as an inline annotation on the diff, so the author sees exactly which line is the problem and what the safe rewrite is.

AWS Billing Bug Shows Customers Trillion-Dollar Estimates While Its Own Cost Alarms Fail to Act

A configuration change in AWS's bill computation system showed customers estimated bills in the billions and trillions of dollars for over 24 hours. AWS's own alarms detected the anomalies but failed to halt bill generation or page engineers; customer escalations alerted the company 4.5 hours later. Budget and cost anomaly alerts were disabled platform-wide during mitigation. By Steef-Jan Wiggers

When a Hybrid App Button Does Nothing

A mobile user taps a button. Nothing opens. There is no validation message, exception, or visible loading state. The control simply appears dead. These bugs are frustrating because the visible symptom is tiny while the real interaction crosses several technical boundaries. I recently investigated this kind of failure in a Blazor Hybrid image workflow. The feature behaved sensibly in a desktop browser, but the same interaction did not reliably open the photo picker inside an iOS WebView. The useful lesson was broader than the eventual CSS change: A native capability launched from hybrid web UI is a cross-layer contract, not a single component event. To make the interaction dependable, the browser gesture, responsive dialog, native application metadata, and automated tests all had to agree. The visible button was not the real control Styled file-upload controls commonly hide the browser's native file input. A label or custom button receives the click and forwards it to the hidden input. That pattern can work well on desktop browsers. It provides visual freedom while retaining a native file-selection control underneath. The implementation I examined had taken the hiding quite far: the real input was clipped to a tiny area, while a separate visible element acted as its proxy. On desktop, the browser carried the user action through that indirection. Inside the iOS WebView, the picker did not open. This matters because browsers deliberately protect privileged actions. File pickers, cameras, pop-ups, clipboards, and media playback often require a trusted user activation. The further the real privileged element is removed from the original tap, the more likely platform differences become visible. The fix was conceptually simple: make the transparent file input span the visible button. The control still looks custom, but the user's tap now lands directly on the input that owns the privileged action. The input is visually transparent, not functionally absent. One repaired lay

Running PostgreSQL with Docker

Installing Postgres directly on your machine works, but it gets messy fast once you're juggling multiple projects that each want different versions, extensions, or seed data. Docker sidesteps all of that you get a clean, disposable Postgres instance per project, and your host machine stays untouched. This guide covers running Postgres in Docker for local development: quick one-off containers, docker-compose for anything you'll come back to, persistent data, and a few things that trip people up. 1. The quickest way to get a Postgres instance running docker run --name my-postgres \ -e POSTGRES_PASSWORD = secret \ -e POSTGRES_USER = devuser \ -e POSTGRES_DB = myapp \ -p 5432:5432 \ -d postgres:16 Breaking that down: --name my-postgres — a friendly name so you can reference the container later instead of a random hash POSTGRES_PASSWORD — required; the container won't start without it POSTGRES_USER / POSTGRES_DB — optional; default to postgres if omitted -p 5432:5432 — maps container port 5432 to host port 5432 -d — detached, runs in the background postgres:16 — pin a version; avoid latest since it can silently jump major versions later Check it's running: docker ps Connect with psql (if installed locally) or from inside the container: docker exec -it my-postgres psql -U devuser -d myapp 2. Using docker-compose for anything persistent For a real project, docker-compose.yml is the better default , it's version-controlled, reproducible, and easy to extend with more services later (Redis, pgAdmin, your app itself). services : db : image : postgres:16 container_name : myapp-postgres restart : unless-stopped environment : POSTGRES_USER : devuser POSTGRES_PASSWORD : secret POSTGRES_DB : myapp ports : - " 5432:5432" volumes : - pgdata:/var/lib/postgresql/data volumes : pgdata : Start it: docker compose up -d Stop it (keeps data): docker compose down Stop and wipe data: docker compose down -v 3. Why the volume matters Without a named volume, all data lives inside the container's

GORM: Dev's Guide to Go's Most Popular ORM

If you're working with Go services that talk to a relational database, chances are you've bumped into GORM . It's the most widely used ORM in the Go ecosystem, and for good reason. It wraps a lot of the tedium of database/sql ,manual scanning, hand-written migrations, string-built queries in a much friendlier API. This article walks through GORM from setup to the patterns you'll actually use day to day: models, migrations, CRUD, associations, transactions, and a few gotchas that trip people up. Why reach for an ORM in Go ? Go's standard database/sql package is deliberately low-level. You write SQL strings, manually scan rows into structs, and manage connections yourself. That's fine for small projects, but it gets repetitive fast once you have a dozen tables and endpoints that all need similar create/read/update/delete logic. GORM sits on top of database/sql and gives you: Struct-based models mapped to tables Auto migrations A chainable query builder Associations (has-one, has-many, many-to-many, belongs-to) Hooks (before/after create, update, delete) Built-in support for transactions, connection pooling, and prepared statements It supports PostgreSQL, MySQL, SQLite, SQL Server, and more, through swappable drivers. Installation go get -u gorm.io/gorm go get -u gorm.io/driver/postgres Swap postgres for mysql , sqlite , or sqlserver depending on your database. Connecting to a database package main import ( "log" "gorm.io/driver/postgres" "gorm.io/gorm" "gorm.io/gorm/logger" ) func main () { dsn := "host=localhost user=postgres password=secret dbname=myapp port=5432 sslmode=disable" db , err := gorm . Open ( postgres . Open ( dsn ), & gorm . Config { Logger : logger . Default . LogMode ( logger . Info ), }) if err != nil { log . Fatalf ( "failed to connect to database: %v" , err ) } sqlDB , err := db . DB () if err != nil { log . Fatalf ( "failed to get generic db object: %v" , err ) } sqlDB . SetMaxOpenConns ( 25 ) sqlDB . SetMaxIdleConns ( 10 ) } That db.DB() call gi
