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

AutoGen's hidden token tax: why a 3-agent chat costs 15× what you expect Cost-audit series, episode 2. This series began with an AI agent that burned 136M tokens overnight → . AutoGen is Microsoft's multi-agent framework. It's genuinely good at orchestrating agents that hand off work to each other. But its default memory model has a cost shape that surprises almost every team that hits it in production. This audit shows you exactly where the tokens go, with line numbers. The setup: a 3-agent RoundRobin chat The canonical AutoGen pattern is a RoundRobinGroupChat with N agents taking turns on a task. Here's the minimal version from the docs: from autogen_agentchat.agents import AssistantAgent from autogen_agentchat.teams import RoundRobinGroupChat from autogen_agentchat.conditions import MaxMessageTermination planner = AssistantAgent ( " planner " , model_client = client , system_message = " You plan. " ) coder = AssistantAgent ( " coder " , model_client = client , system_message = " You code. " ) reviewer = AssistantAgent ( " reviewer " , model_client = client , system_message = " You review. " ) team = RoundRobinGroupChat ( [ planner , coder , reviewer ], termination_condition = MaxMessageTermination ( max_messages = 10 ), ) await team . run ( task = " Build a web scraper for Hacker News. " ) Three agents, 10 turns total (~3–4 turns each). Seems cheap. It isn't. The default context: unbounded, per-agent Every AssistantAgent gets its own UnboundedChatCompletionContext by default: # autogen-agentchat/src/autogen_agentchat/agents/_assistant_agent.py, __init__ (L708) if model_context is not None : self . _model_context = model_context else : self . _model_context = UnboundedChatCompletionContext () source UnboundedChatCompletionContext.get_messages() returns self._messages — the full list, no cap, no truncation: # autogen-core/.../model_context/_unbounded_chat_completion_context.py (a ~20-line file) async def get_messages ( self ) -> List [ LLMMessage ]: """ Get at most

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

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

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

For quite a while now, I've had the feeling that AI agents are surrounded by this mystical aura....

We spent the last months consolidating seven separate sequence classifiers into one multi-head model, our apex model, so to speak, and since the weights are now public, I wanted to share what worked and what surprised us. Setup: a shared mmBERT-small encoder with seven task heads, binary injection (BCE), document class (7-way), tool type (14-way), tool operation (6-way), tool data-flow tags (3× BCE, multi-label), intent routing (5-way), and threat type (7-way). The part that needed care: our training rows only carry labels for a subset of tasks, so absent tasks are masked out of the loss entirely. We ended up writing a self-test that asserts absent-task gradients are exactly zero, which caught two subtle bugs, and I'd recommend it to anyone doing similar masking. About 5k synthetic/real multi-task rows help the heads co-train; the test sets stay 100 % real data. Held-out results per head: injection F1 0.962, documents 0.980, tool type 0.957, tool operation 0.945, tool tags 0.958, routing 0.916, threat 0.952. Quantization: both the unified model and the dedicated single-task variants ship quantized -edge builds (ONNX INT8 + INT4 embeddings, from 96 MB) with measured parity benchmarks in the repos, the worst head loses 0.012 against FP32. Was it worth it vs. seven dedicated models? We released both variants, so you can judge for yourself, the dedicated models score marginally higher on most tasks, but the unified one does one encoder pass instead of up to seven. Our weak spot: routing, at 0.916. The intent classes overlap semantically ("write code that analyzes my data" is that code or analytics?), and I suspect the ambiguity is genuinely in the data. If you have ideas beyond relabeling, let me know :) Weights and per-head metrics: https://huggingface.co/patronus-studio submitted by /u/PatronusProtect [link] [留言]

Hey, I would like to show you my project, but it's difficult because it only works with a registration, so I explain the concept to you. The Idea: Everyone who registers has to do an onboarding and answer meaningful questions that help you to find a right match. The matching happens by the system. Once you're done with the onboarding, you enter the pool. When a match is found, you go into a 1on1 14 question-set with that person. All answers are revealed immediately. At the end both decide if the

Less than a week before Meta's lawyers were set to return to a Los Angeles courtroom, the plaintiff accusing the platform of inflicting harm dropped the case. Brought by 15-year-old Florida plaintiff going by initials R.K.C., the case was set to be the second in a set of bellwether trials meant to test legal arguments […]

Hello. I really liked stackoverflow >5 years ago. There were many people asking about easy-to-medium problems to be solved, and it was a great way for me to learn C/C++/Bash/awk/sed/cmake/Linux/whatever by solving real-life(!) mediocre problems and also helping people in the process and also being criticized and corrected at the same time, from which I learned triple as much. Now stackoverflow is dead. My almost 150k reputation means nothing. Finally they added a "advice" type of questions which is way way too late. Now I lurk over reddit for typic-specific type of questions, but reddit is more a social network then help-me-with-programming-problem site, and the "help me" part is anyway so easy to solve with an AI. It was great back then - the feeling of learning something new and at the same actually helping and actually feeling like an expert in something. I learned the C programming standard by heart by answering really niche questions about C program behaviors. This was really fun for me. I enjoyed the specificity of stackoverflow - the idea of being "exact", answering only the question asked. There are just no questions nowadays on stackoverflow. There is a void now. And AI. There are topic-specific Discord chats, as a modern replacement of IRC, but I always assumed they are used by developers, not for noobs. I know the times without AI will never come again, but the internet, the thing connecting people across the whole globe, just feels more empty, more robotic and like an advertisement nowadays. submitted by /u/kolorcuk [link] [留言]
