This is a submission for the June Solstice Game Jam What I Built Perfume Calendar: June is a small atmospheric adventure game inspired by nature, folklore, and the changing moods of June. Players take on the role of Mavka , a forest spirit, and travel across a calendar-shaped map representing the 30 days of the month. Each day has a different nature element—forest, sun, water, or mist—that affects the player's energy. The goal is to make strategic movement choices, gather enough energy from beneficial days, and reach June 21st , the summer solstice, with at least 10 energy points. If successful, Mavka awakens the forest and completes her journey. My intended goal was to create a simple but thematic experience where a calendar becomes an interactive game board rather than just a way to track dates. I wanted players to feel like they were moving through a living month, with each day offering different opportunities and risks. The game relates to the challenge theme by transforming a calendar into the core gameplay mechanic. Instead of simply displaying dates, the days themselves become locations that influence the player's progress. The June setting, seasonal energy, and the solstice objective reinforce the idea of time, nature, and progression through a month in a playful and interactive way. Video Demo Code wailixi / Mavka Game How I Built It I built the game using HTML, CSS, and JavaScript without any external libraries. The 30 days of June are displayed as a 6×5 grid , where each day has a terrain type (forest, sun, water, or mist) that affects the player's energy. A key design choice was turning the calendar into a navigable map. Players move Mavka between days, collect energy, and plan their route to reach June 21st with enough energy to win. Movement restrictions add a simple strategy element, while color-coded terrain helps communicate each day's effect. My goal was to create a small, atmospheric game that transforms a calendar into an interactive adventure in

Most of Kenya’s power grid runs on renewables. But with 25% of communities lacking centralized electricity, the nation is looking to off-grid solar to hit its goal of delivering universal electricity access by 2030 without driving up emissions. The ever-­improving economics of solar technology have helped. A couple of years ago, a panel cost about…

GitHub has introduced the GitHub Copilot app, a desktop control centre for agent-native development that aims to keep engineers in charge while AI agents handle more coding work. Mario Rodriguez writes on the GitHub blog that the recent wave of coding agents has brought faster delivery but also "disjointed workflows, more context switching, and too much time spent reviewing agent-generated code".

You run a Telegram bot through OpenClaw on your own Linux server. One day it goes quiet. The bot can't send or receive. But the server itself is fine — SSH works, apt works, other sites load. The reason: your server can't reach api.telegram.org . Some networks block or throttle it, so every call times out while everything else is fine. The clean fix: route only OpenClaw's Telegram traffic through Cloudflare WARP (1.1.1.1) . Everything else on the box stays direct and fast — including your SSH login. Here is the full setup, step by step. First, confirm it's a Telegram-only problem curl --max-time 8 https://api.telegram.org/ # hangs / times out curl --max-time 8 https://www.google.com/ # works instantly If Telegram times out but other sites are quick, this guide is for you. How it works We chain three small tools: OpenClaw ──▶ iptables ──▶ redsocks ──▶ WARP (SOCKS5) ──▶ Cloudflare ──▶ api.telegram.org WARP gives us a local proxy that exits through Cloudflare's network (which can reach Telegram). redsocks turns normal connections into proxy connections (so the app needs no proxy support — OpenClaw has none). iptables picks only OpenClaw's Telegram traffic and sends it to redsocks. The trick is in that last step. We match by the app's user and Telegram's IP ranges, so nothing else is touched. Step 1: Install WARP in proxy mode # Add Cloudflare's package repo curl -fsSL https://pkg.cloudflareclient.com/pubkey.gpg \ | gpg --yes --dearmor -o /usr/share/keyrings/cloudflare-warp-archive-keyring.gpg echo "deb [signed-by=/usr/share/keyrings/cloudflare-warp-archive-keyring.gpg] \ https://pkg.cloudflareclient.com/ $( lsb_release -cs ) main" \ > /etc/apt/sources.list.d/cloudflare-client.list apt-get update && apt-get install -y cloudflare-warp # Sign up (free) and switch to proxy mode warp-cli --accept-tos registration new warp-cli --accept-tos mode proxy # opens a SOCKS5 proxy on 127.0.0.1:40000 warp-cli --accept-tos connect Now check that WARP can reach Telegram: curl --socks5-

How I replaced Google Photos, Google Drive, and Google Home with a self-hosted Raspberry Pi 5 setup - and what the full technical stack looks like. There's a quiet moment every tech-literate person eventually hits. You open your cloud storage dashboard, see the number creeping up, and think: I'm paying a subscription fee, every month, forever, just to store my own photos and files on someone else's computer. That was me, but with a bit of added weight. It's not just my data I'm responsible for. Over the years, I've quietly become the unofficial digital curator for my entire family . The person everyone sends photos to after a birthday party. The one who backs up the wedding videos. The one who scans and stores the important documents, passports, contracts, and sentimental things so they don't get lost. My parents, siblings, extended family: if something matters and it's digital, there's a good chance it eventually lands with me. That's a responsibility I take seriously. And for a long time, Google was my answer - until the storage bill started quietly creeping past 2TB, and I started thinking more carefully about what it actually means to hand all of that data over to "big tech" . So I built my own home server. A tiny, almost silent box sitting in my house that now handles everything Google Drive and Google Photos did, plus more, for a one-time hardware cost of £340. This is the story of how I did it, why I did it, and exactly how you can too. Why I Did It The cost was the trigger, but it wasn't the only reason. When you use Google Photos, Google Drive, or any cloud storage service, your files live on their servers. You're trusting a corporation to keep them safe, not snoop through them, not change their pricing, and not shut down the product one day. Google has a long history of killing beloved products. Google Photos itself famously ended its unlimited free tier in 2021. As well as this, recent AI trends and auto opt-in data processing had me thinking there had to

json.loads(response) fails at a certain point. You told the model "return JSON only," but it added a ```json markdown code fence around everything. A quick regex strips it — until that regex hits an edge case, and that edge case blows up in production. Since Ollama 0.3.0, passing a JSON schema to the format parameter eliminates this problem at the root. The model's inference itself is constrained by the schema, so no code fences, no explanatory text, no mid-thought artifacts. Just parseable JSON. I ran these tests locally with Gemma4 and Ollama 0.30.7 to see how well it holds up in practice. Why LLM Response Parsing Is Tricky The most common problem when running Ollama locally — without a cloud LLM API — is JSON parsing. Two reasons. First, text generation models are trained toward "natural text." Even if you ask for JSON only, they'll often wrap it in json ... blocks or prepend "Of course! Here is the JSON you requested:" style text. Here's what I reproduced directly: json Input: 'Give me 3 Python tips as JSON with keys: tips (array), difficulty (1-5)' Model output (no format parameter): ```json { "tips": [ "Master the fundamentals first...", ... ] } JSON parse: FAILED Python ' s `json.loads()` can ' t handle the markdown wrapper . The " JSON only " instruction is unreliable in production . Second , speed . I measured the same query both ways : 32 seconds without structured output , 5 seconds with it . More on why below . ## How the Ollama format Parameter Works Ollama ' s `/api/generate` endpoint has a `format` field. Pass a JSON schema object and Ollama applies **constrained decoding** during inference. python import json import urllib.request def ollama_structured(prompt, schema, model="gemma4:e4b"): payload = { "model": model, "prompt": prompt, "format": schema, # ← pass JSON schema object directly "stream": False, "options": {"temperature": 0} } data = json.dumps(payload).encode() req = urllib.request.Request( " http://localhost:11434/api/generate ", data=data

One of the most persistent traps in modern software development is the tendency to turn architectural styles into absolute dogmas. We see it constantly on social media and inside engineering rooms: teams arguing over cloud native versus cloud agnostic as if they are choosing a lifelong political alignment. A recent perspective from the engineering team at GeekyAnts titled "Cloud-Native and Cloud-Agnostic Are Not Ideologies; They Are Business-Stage Decisions" cuts through this industry noise. Looking critically at their argument, it becomes clear that many organizations are suffering from premature architectural complexity. Engineering leaders frequently romanticize absolute portability long before their business has the operational maturity or the market validation to justify it. The core takeaway is simple yet profound: your architectural choice should be a reflection of your business stage, not a philosophical stance. The Go To Market Trap In the earliest stages of a business, the primary goal is not infinite scalability. The primary goal is survival. A startup needs to discover product market fit before running out of capital. This requires maximum release velocity, rapid experimentation, and minimum operational overhead. For an early stage company, leveraging a cloud native approach is entirely rational. Relying on managed databases, serverless functions, provider native identity management, and integrated monitoring allows a tiny engineering team to focus entirely on product features. The critical flaw in many early architecture reviews is treating this cloud dependency as a failure. It is actually a deliberate speed asset. At this stage, worrying about vendor lock in is a distraction because if you do not find customers quickly, there will be no vendor left to be locked into. Changing Priorities as the Business Matures The architecture that helps a company launch is rarely the one that sustains its long term growth. As a software product gains traction, the op

The Playwright Playbook — Part 3: Multi-User, Multi-Tab & Browser Context Testing "Most frameworks test one user at a time. Real apps don't work that way." In Part 1, we built the full foundation — POM, storageState , fixtures, and a clean project structure. In Part 2, we took control of the network layer — mocking APIs, simulating failures, and asserting on real network calls. Now we tackle the scenario that breaks most automation frameworks. Multiple users. Simultaneously. In one test. Think about your app for a moment. How many features actually involve just one user? Admin assigns a task → regular user sees it appear in real time User A edits a record → User B gets a notification Admin revokes access → User's session should invalidate Two users try to edit the same record → conflict resolution kicks in These are real features. They need to be tested. And page.goto('/login') in a beforeEach won't get you there. Playwright's browser context architecture was built exactly for this. Let's use it properly. 🎯 🏗️ Where We Left Off After Part 2, our project looks like this: playwright-playbook/ ├── tests/ │ ├── auth/ │ │ └── login.spec.ts ✅ Part 1 │ ├── tasks/ │ │ └── task-management.spec.ts ✅ Part 1 │ └── network/ ✅ Part 2 │ ├── api-mocking.spec.ts │ ├── error-simulation.spec.ts │ └── network-assertions.spec.ts ├── pages/ │ ├── LoginPage.ts ✅ Part 1 │ └── TaskPage.ts ✅ Part 1 ├── fixtures/ │ ├── auth.fixture.ts ✅ Part 1 │ ├── tasks.json ✅ Part 2 │ ├── empty-tasks.json ✅ Part 2 │ └── tasks-har.har ✅ Part 2 ├── scripts/ │ └── record-har.ts ✅ Part 2 ├── .auth/ │ ├── admin.json │ └── user.json ├── global-setup.ts ✅ Part 1 ├── playwright.config.ts ✅ Part 1 └── .env By the end of Part 3, we add: playwright-playbook/ ├── tests/ │ ├── multi-user/ ← NEW │ │ ├── role-permissions.spec.ts │ │ └── realtime-collaboration.spec.ts │ └── multi-tab/ ← NEW │ └── multi-tab-flows.spec.ts ├── pages/ │ └── DashboardPage.ts ← NEW ├── fixtures/ │ └── multi-user.fixture.ts ← NEW Every one of th

This is a submission for the June Solstice Game Jam What I Built My game, Sunny Up, celebrates International Sushi Day! I intended to make a cute casual game because who doesn't like simple and cute things, right? I was inspired by games I liked in the 2010s that were simple, fun, and strangely addictive. The game's theme also has a lot to do with the solstice, which can be observed in the four scenarios where the game makes reference to it. Video Demo Code maikpalharoni1 / sunny-up my game sunny up for june solstice game jam sunny-up my game sunny up for june solstice game jam View on GitHub How I Built It Fun fact: I started brainstorming the idea while I was working on another game, a cute virtual pet (which even celebrates a traditional festival in my country in June, called Festa Junina), and in doing so I became obsessed with the stories of virtual pet developers from the 2010s. I mainly read about Paul Salameh and his game Pou, and also about Rovio with Angry Birds, which were my favorite stories. I combined two mechanics from both games, and that's where I decided how the game would work. I'm a noble pioneer of HTML, CSS, and JS, so I used AI to give me greater support, optimization, and help me write the code in parts of the project. I'm not a designer, nor can I afford one. I used Gemini AI for the game's graphics, acting as an art director to ensure everything came out as best as possible, removing the AI ​​sloppy aspect and giving the project more life. Prize Category I really liked the artwork with Gemini and the emotional support and evaluation of Google's AI mode, so I think it's worth considering for the Best Use of Google AI category, even though I'm not aiming for any specific category. Play the game Online in browser on Itch.io: https://coffee-calf.itch.io/sunny-up Thank you for reading, it was fun participating in the challenge!

Playwright is the best browser automation library in 2026. It's also the most fingerprinted, the most detected, and the most patched in anti-bot databases. If you're running default Playwright against any platform with serious anti-bot defenses, you're getting flagged. We learned what's left of the cat-and-mouse game the hard way building HelperX . This article is what still trips up Playwright today — beyond the well-known navigator.webdriver flag, which everyone fixes in week one. The detection surface has shifted dramatically since 2022. The classic tells (PhantomJS, missing plugins, undefined chrome object) are largely solved. The new battleground is more subtle: CDP protocol artifacts, behavioral inconsistencies, and side-effects of the Playwright runtime that aren't part of the public API. What stopped working in 2024-2025 Detection on the platforms we monitor has gotten dramatically better in the last 18 months. A few things that worked in 2023 and stopped working since: Generic navigator.webdriver = undefined patches — detectable via Object.getOwnPropertyDescriptor if you do it naively Patching Notification.permission — modern detection cross-references with Permissions.query() Faking window.chrome — the property structure changed; old fakes are missing newer subkeys Setting a single User-Agent profile — detection now expects Client Hints to match Empty navigator.languages — flagged as suspicious; needs at least 2 entries These were all "set it once, ship it" fixes. The current generation of detection requires ongoing engineering. CDP artifacts: the deepest tell The Chrome DevTools Protocol (CDP) is how Playwright controls the browser. The browser exposes signals that it's being controlled, and modern detection looks for them specifically. Symptom: Runtime.evaluate artifacts When you run await page.evaluate(() => ...) , Playwright uses Runtime.evaluate under the hood. The evaluated script runs in a special isolated world. If the page can detect that an isola

In this blog post, we will see how I use Qwen Code's slash commands and workflow strategies to build Achu my screenshot beautifier app without burning through tokens or losing context mid-session. If you haven't heard of Achu , it's a desktop app built with Electron + React + TypeScript. It does screenshot beautification, Privacy Guard (offline OCR redaction), Auto-Vibe (palette-extracted backgrounds), and an AI Bug Agent with GitHub integration. It's a side project I'm genuinely proud of, and Qwen Code has become my go-to agentic coding CLI for it. A developer shares their day-to-day workflow for using Qwen Code, an open-source agentic coding CLI, to build Achu, a desktop screenshot beautification app built with Electron, React, and TypeScript. The post covers how slash commands like /init, /plan, /compress, /remember, and /btw are used to manage context, reduce token costs, and maintain consistent output across sessions. The core approach centers on spec-driven planning through iterative /plan sessions before any code is written, combined with parallel subagents for independent tasks and strict context hygiene using /compress and /clear. Additional practices include pointing the model at library source code instead of documentation and using /remember to persist architectural decisions across sessions. This isn't a tutorial about what Qwen Code is. It's about how I actually use it day-to-day, the slash command tricks I rely on, and the discipline it takes to get real work done with an LLM in a terminal. It all started with Google Antigravity, but the 5 hours reset and weekly limits is killing my productivity and thinking flow. I had to switch to more affordable and open source model where I chose Qwen. Why Qwen Code? I've tried Claude Code, Gemini CLI, and a bunch of others. Qwen Code is open source, has excellent subagent support, a rich slash command system, and Qwen Max is genuinely strong at reasoning through complex TypeScript and Electron internals. My go-to

Coding agents draft specs, architecture docs, changelogs, and README updates in seconds — but a human still has to judge the quality of all that output. The bottleneck shift A year ago, the typical workflow was: you write a spec, you get comments, you revise, then you implement and get code review. Humans did most of the writing and coding. Now, agents produce first drafts of design docs, API references, runbooks, and onboarding guides — and they do it in seconds. Code implementation and code review can now be handled by agents, so those are no longer the bottleneck. What surfaced instead is the step right before: document review. A human has to read 2,000 lines of generated markdown and decide what's wrong. The writing part got dramatically faster. LLMs can assist with document review too, but compared to code implementation and code review, the human judgment required is still larger. This asymmetry compounds fast. Every agent-assisted project now has a stack of "needs human review" documents growing in a shared folder. If you're running multiple agent loops in parallel — one for the spec, one for the implementation plan, one for the test strategy — review becomes a pipeline stall. GitHub PRs remain the right tool when you need third-party review. But the step before that — the fast local self-review loop where you and your agent iterate on a draft — doesn't belong in a PR. Branching, diffing, and assigning reviewers is a lot of process for a first draft the agent wrote in seconds. Why prose feedback is lossy The most common workaround today is to have the agent read the document and then fix things based on natural-language feedback: "The error handling in section 3.2 is too vague — be specific about what happens on timeout." This looks reasonable. The agent reads it, searches for something about error handling, and makes a change. But several things go wrong: Position is ambiguous. If section 3.2 has three paragraphs about error handling, which one did the revie

vibe citing: how KPMG used AI to write a report about AI and AI made them look like fools by t474-r0b07 There are companies that charge you to tell you how to use AI responsibly. KPMG is one of them. 250,000 employees. 138 countries. Decades advising governments and corporations on how to avoid costly mistakes. In October 2025 they published a report titled "Total Experience: Redefining Excellence in the Age of Agentic AI" . They wrote it with AI. The AI invented 88% of the sources. Nobody verified anything. They published it anyway. // what is "agentic AI" — because the title matters An agentic AI is not a chatbot. Not the assistant that answers your questions. It's a system that makes decisions and executes actions on its own, without a human approving each step. You give it an objective and it acts, corrects, moves forward. It's the product everyone in the tech sector was selling in 2025. KPMG was selling it too. That's why they needed a report proving their clients were already using it. Spoiler: they weren't. And the report invented it anyway. // the forensic analysis GPTZero — a company specialized in detecting AI-generated content — ran a full audit on the report. First: what is an AI hallucination, because the term is going to come up a lot. When a language model doesn't have the information you ask for, it doesn't say "I don't know." It generates a response that sounds correct. It invents with the same confidence it would use if it actually knew the truth. Perfect format. False content. No warning. That's a hallucination. Now the numbers from the KPMG report: TOTAL CITATIONS: 45 REAL CITATIONS: 5 INVENTED CITATIONS: 40 ACCURACY RATE: 11.1% 40 of 45 citations have invented titles, authors that don't exist, or sources that don't say what KPMG claimed they said. Half of the factual claims in the report are false or misattributed. A firm that charges for intellectual rigor published a document with 11% accuracy. // the organizations that read the report and sai

We’ve all heard "it works on my machine," but when it comes to AI-driven features, that phrase is a recipe for disaster. You can have a perfectly tested agent today, but if you upgrade your base model or change your quantization strategy tomorrow, you might inadvertently kill your agent's reliability. You can’t afford to wait for production to find out your agent is hallucinating or failing its tool calls. This is why we built the headless QuantaMind CLI—to shift AI evaluation left into your CI/CD pipeline. By integrating custom eval JSON collections into your build process, you can now treat your AI agent like any other piece of code. If a model upgrade or a quantization tweak causes your agentic reliability to dip below your required threshold, your CI pipeline should block that merge. It’s not just about testing; it’s about enforcement. If you aren’t gating your deployments based on real, repeatable model performance, you aren’t shipping software—you’re shipping a guessing game.

Every tool call, every structured output, every agent decision travels as JSON. Here is the serialization knowledge that separates the amateur from the architect — now that the stakes have never been higher. A developer ships an AI agent on a Friday. In the demo it's flawless: the model reads a request, calls a tool, returns a clean answer the app renders perfectly. A week later, production dashboards are full of garbage. A date is showing up as raw text. A field that was definitely there is silently gone. Under one big payload, the whole server froze for two seconds. And here's the maddening part — nothing threw an error. The model returned JSON. The code parsed it. Everything "worked." The bug wasn't in the model, and it wasn't in the parser. It lived in the narrow gap between text and data — the place every JSON value has to cross twice. That gap is serialization , and in 2026 it has quietly become one of the most important things a JavaScript engineer can actually understand. Why now? Because the most important conversations in modern software aren't between humans anymore. They're between models and machines — an LLM deciding which tool to call, a server answering, an agent chaining ten steps together. And every one of those conversations happens in the same format: JSON. So let's open up the refinery and see how raw structure becomes a clean stream of bytes — and back again — without losing anything precious on the way. JSON is not a JavaScript object This is the misunderstanding that creates most JSON bugs, so it's worth saying plainly: JSON only looks like a JavaScript object. It isn't one. JSON is a transport format — flat, inert text meant to travel across a network or sit on a disk. A JavaScript object is a live structure in memory that your application can read, mutate, and call methods on. They resemble each other the way a flat-packed cardboard box resembles assembled furniture: same thing in spirit, completely different states. const user = { name : "

How I Cut Costs 65% Migrating LangChain to DeepSeek I want to tell you about a switch I made recently that genuinely surprised me. If you're running LangChain in production and haven't explored the DeepSeek models yet, this one's for you. Let me show you what I learned, what broke, and what I'll never go back to. The short version? I was burning cash on a generic LLM setup. I migrated to DeepSeek through Global API's unified interface, and my monthly inference bill dropped by over 60%. Setup took me less time than brewing coffee. Let me walk you through it. Why I Even Looked at This in the First Place Here's the thing about working in AI engineering: the model landscape moves so fast that whatever you chose six months ago is probably overpriced now. That's been my experience, anyway. When I first built my LangChain pipeline, I defaulted to a popular name-brand model because, well, that's what everyone was using. It worked. It was fine. Then I looked at my AWS bill. That's when I started digging into alternatives. And let me tell you, the rabbit hole is deep. Global API alone exposes 184 AI models at prices ranging from $0.01 to $3.50 per million tokens. That's a wild spread. The trick is finding the sweet spot where cost meets quality, and for migration workloads (think: code translation, schema conversion, content rewrites), I found it with DeepSeek. Let me show you the numbers that actually mattered to me. The Pricing Reality Nobody Talks About I built a comparison table when I was making this decision, and I want to share it because staring at these numbers side by side is what convinced me. Here's the lineup I evaluated through Global API: DeepSeek V4 Flash sits at $0.27 per million input tokens and $1.10 per million output tokens, with a 128K context window. That's my default for most production traffic now. Fast, cheap, and smart enough for almost everything. DeepSeek V4 Pro comes in at $0.55 input and $2.20 output with a beefier 200K context. I use this when
