Bizbox Build Log — Week of 2026-05-31

Shipped this week Workflows are now a first-class Bizbox primitive — PR #86 · v2026.603.0 The biggest drop this week. @DennisDenuto landed Workflows as a company-scoped concept that sits alongside issues and routines — not shoehorned into either. What that means in practice: Google ADK-backed execution — workflow pipelines run as ADK agents, with phase state persisted as run records. Human handoffs baked in — pipelines can pause and wait for a human before resuming. Deliverables that survive — artefacts from each run are persisted and surfaced in the UI. A pipeline graph in the UI — topologically ordered, showing live phase state and console output. This is the foundation. More on what we can build on top of it below. Workflow human-handoffs now route through ClickUp — PR #91 · v2026.605.0 The day after Workflows landed, @angelofallars wired up the last kilometre: when ADK Python code calls input() inside a pipeline, Bizbox now intercepts that call and sends a ClickUp message to collect the human reply — instead of blocking the process forever. A few things that were fixed along the way: input() monkey-patching now works consistently across Python environments (was silently failing in some setups). Failed workflow runs no longer submit deliverables. You only see artefacts from runs that actually completed. ClickUp awaiting-human bridge adapter ships as a pure plugin — PR #78 · v2026.601.0 This one technically crossed the line on the last day of May (23:56 UTC, 31 May), so it's in scope. @ralphbibera ported the ClickUp transport and adapter as a genuine plugin — implementing the AwaitingHumanBridgeAdapter registry interface — without touching bridge core at all. What that gives you: ClickUp works through the same provider-agnostic layer as any future provider (Slack, Discord, whatever comes next). The core doesn't know ClickUp exists. Included: send/poll/reaction transport, message templates for request_confirmation and ask_user_questions interactions, brain_is_think

Treating Firestore as a public cache

Using Firestore as "the app's primary database" is easy at first. Writes and reads complete in one place, and onSnapshot gives you realtime push for free. But as a service grows, keeping Firestore as the SoT (source of truth) exposes some fatal constraints. Where SoT-Firestore hurts Weak transaction boundaries, missing complex queries, the cost structure, the difficulty of migrating away. The harshest one: you cannot narrow related updates with a WHERE . For the use case "update a set of documents matching a condition, consistently, in one go," Firestore is structurally weak. Redefining it as a public cache In one project, I made Cloud SQL the SoT and treated Firestore as a "read-optimized projection." Writes go through the backend (Next.js / Cloud Run), and the SoT (Cloud SQL via Data Connect) and Firestore are both updated within the same write path . Separately, a Cloud Run reconciliation job runs and checks and repairs consistency against the SoT as authoritative. This reconciliation job is enqueued at the start of the request, before the DB updates. Because it's queued first, even if the write dies halfway, the consistency check always runs afterward and repairs the state. From the client's perspective, Firestore is a rebuildable cache — in the worst case it can be rebuilt from the SoT. // Writes go through the backend. The backend updates both the SoT // (Data Connect → Cloud SQL) and Firestore. Clients never write Firestore directly. await backend . updateEntity ({ id , title }); // Changes are pushed back in realtime via Firestore's onSnapshot unsubscribe = onSnapshot ( entityRef , ( snap ) => render ( snap . data ())); Benefits and costs The benefits are clear. The SoT side (SQL) brings transactional consistency and complex queries; the read side (Firestore) brings freedom in data modeling and realtime push; and consistent syncing with external systems (OpenSearch / BigQuery, etc.) coexists naturally. Since the backend updates Firestore at write time, the f

Serverless: When It Helps and When It Hurts

Introduction Serverless computing has become a buzzword in cloud architecture. But like any tool, it has sweet spots and sharp edges. After building and maintaining several serverless applications, I've learned where it shines and where it creates headaches. This article shares those lessons. When Serverless Helps 1. Event-Driven Workloads Serverless excels when your code runs in response to events: file uploads, database changes, HTTP requests. The pay-per-execution model means you don't pay for idle time. // AWS Lambda handler for image resizing exports . handler = async ( event ) => { const bucket = event . Records [ 0 ]. s3 . bucket . name ; const key = event . Records [ 0 ]. s3 . object . key ; // resize and save return { statusCode : 200 }; }; 2. Variable or Unpredictable Traffic If your app has occasional spikes (e.g., a marketing campaign), serverless auto-scales instantly. No need to provision for peak load. 3. Rapid Prototyping and MVPs You can deploy a fully functional API in minutes without managing servers. This accelerates feedback loops. 4. Microservices and Glue Code Serverless functions are perfect for small, single-purpose services that connect other services (e.g., processing webhooks, data transformation). When Serverless Hurts 1. Long-Running Processes Most providers have a maximum execution timeout (e.g., 15 minutes for AWS Lambda). Batch processing or video transcoding may hit this limit. # This will timeout if processing takes > 15 minutes def handler ( event , context ): process_large_file ( event [ ' file ' ]) return { ' done ' : True } 2. Cold Starts After a period of inactivity, the first request may have a delay of several seconds. This is detrimental for latency-sensitive applications like synchronous APIs. 3. Stateful Applications Serverless is stateless by design. If you need persistent connections (e.g., WebSockets) or local state, you'll need additional services like Redis or DynamoDB, adding complexity. 4. High, Steady Load If your

Show HN: Vivace – A single-process Qt media player with interactive DVD menus

Vivace uses only Qt (v6.11.1 or newer) itself — no Qt Widgets, no external player processes. I built it because I wanted SMPlayer's UI conventions and features without depending on the external player processes(mpv/mplayer). It's a ground-up rewrite, not a fork. - DVD playback with interactive menus, from a from-scratch IFO/PCI parser (no libdvdnav) - a hybrid WSOLA + phase-vocoder approach to speed-adjusted audio, since neither algorithm alone sounds good in both directions - secure credential
