Building NICHLYST: How to Code a Survival Engine When You Are Failing to Survive I track everything. It is an occupational habit of a systems architect. You cannot fix what you do not measure — not a failing build, not a leaking color, and not developer burnout. And if you are reading this while grinding through the RevenueCat Shipaton 2026 yourself, you already know that the hardest metric to log honestly is your own state. So, let me share some metrics. Clinical Baseline: A PHQ-9 Depression Score of 21 On May 11, 2026, my clinical assessment scores were: PHQ-9 (Depression): 21. Severe. Immediate professional intervention required. GAD-7 (Anxiety): 11. Moderate. On August 22, 2026, in the middle of the RevenueCat Shipaton, I took the assessment again. PHQ-9: 21. No improvement. GAD-7: 16. High anxiety. Daily functioning severely impaired. If you have never read a GAD-7 anxiety assessment, 16 sits deep in the high-anxiety band — the zone where "daily functioning severely impaired" stops being a clinical phrase and becomes your actual schedule. While I was typing the very first lines of this post, a massive explosion went off, loud enough to make my ears pop. About an hour later, the local news feeds brought the context: an attack drone had been shot down over a park roughly two and a half kilometers from my house. According to the updates, the falling debris killed a two-year-old child and injured two adults. I am developing a narrative game about survival, the fragility of life, and human behavior under immense pressure. But here, in Kyiv, these are not abstract game mechanics or dramatic tropes to be monetized. They are the immediate, absurd, and brutal reality outside my window. I am exhausted. The clinical scores haven't moved in months. I sleep in the middle of the day because my nervous system simply shuts down. I am looking at this hackathon as a final, desperate push to build something sustainable. But here is the thing about the antifragile development plan

A inteligência artificial no setor jurídico ultrapassou a fase dos chatbots genéricos de pergunta e resposta. Quando lidamos com o Direito, o custo de uma "alucinação" de IA não é apenas um incômodo — pode significar a perda de um prazo fatal, uma tese fundamentada em jurisprudência inexistente ou a violação de sigilo. Para resolver esse problema, a engenharia de software aplicada a LegalTechs está migrando para os Agentic AI Workflows (Workflows de IA Agêntica). Em vez de depender de um único prompt gigantesco para resolver um problema complexo, orquestramos múltiplos agentes especializados. Neste artigo, vamos detalhar como arquitetar uma esteira de triagem, busca vetorial e sumarização de processos, utilizando ferramentas maduras e garantindo que o advogado permaneça como o orquestrador final no Quality Gate . 1. Dividir para Conquistar: A Arquitetura Multi-Agente A premissa da orquestração de agentes é a especialização. Cada agente no sistema possui um escopo restrito, ferramentas específicas ( tool use ) e um objetivo claro. Em um cenário de entrada de um novo processo longo (ex: um PDF de 500 páginas), o workflow se divide em três estágios: Agente 1: Classificação de Intenção e Roteamento O primeiro agente atua como o recepcionista. Ele não lê o documento para extrair teses; ele apenas analisa as primeiras páginas para responder: O que é isso? É uma Inicial Trabalhista? Uma intimação de prazo? Uma contestação? A partir dessa classificação, o workflow roteia o documento para a fila correta de processamento. Agente 2: RAG (Retrieval-Augmented Generation) e Busca Vetorial O segundo agente é o pesquisador. Ele quebra o documento em fragmentos ( chunks ) e cruza as alegações da parte contrária com o acervo interno do escritório. No ecossistema Elixir, por exemplo, podemos utilizar o PostgreSQL com pgvector e Ecto para armazenar os embeddings de casos passados e jurisprudências vencedoras do próprio escritório. O agente busca semelhanças e recupera o contexto estrit

🚀 MyZubster Dev Update — Building the Zorgax Monetization Layer We’ve completed another important step toward making Zorgax not only an AI and research layer, but also a service that autonomous agents, applications, and users can interact with economically. This development introduces a new monetization architecture built on top of the MyZubster Payment Layer. What’s now implemented: • Server-side Zorgax product catalog and pricing • Credit accounts for users and services • Append-only credit ledger for auditable transactions • Purchase records bound to Payment Intents • Server-controlled credit grants — clients cannot decide prices or credit amounts • Idempotent credit allocation to prevent duplicate grants • Usage debiting with replay protection • Ownership isolation between users • Authenticated monetization API endpoints • Integration with the MyZubster Payment Intent architecture • Bitcoin payment rail compatibility, disabled by default until production infrastructure is ready The flow we are building is: Zorgax Service → Product & Pricing → Payment Intent → Payment Verification → Credits → Entitlement / Service Access → Usage A key design principle is that payment confirmation alone is not enough to arbitrarily create credits. The server keeps the authoritative relationship between the Zorgax product, its price, the Payment Intent, and the credits that can be granted. This gives us a foundation for future use cases such as: 🤖 AI agent services 🔬 Research and knowledge services ⚙️ Autonomous agent execution 🌐 API usage 🌱 MyZubster LIFE environmental services 🏪 Marketplace services and bounties 📡 IoT and machine-to-machine services ₿ Bitcoin and future machine-payment rails Security and accounting were treated as protocol requirements from the beginning: integer satoshis, transaction idempotency, anti-replay protections, server-side pricing, ownership checks, and auditable credit movements. Current validation: ✅ 8 test suites passing ✅ 69 automated tests passing

Note: This tutorial was originally published on effessdev.github.io . Check out the original article for the most up-to-date version: https://effessdev.github.io/posts/2026-07-27/ This is a step-by-step tutorial that explains how you can set up your development environment for working with ESP-IDF projects in VS Code . Install ESP-IDF Install EIM Espressif Systems provides a graphical tool called EIM (ESP-IDF Installation Manager) to install ESP-IDF. Click the link below to go to the official page to download EIM: https://dl.espressif.com/dl/eim/ Make sure you are in the "Online Installer" tab. The exact file to download depends on your system: Windows: Download eim-gui-windows-x64.exe . Run this installer to install EIM. Linux x64 (Ubuntu): Download and install the .deb package ( eim-gui-linux-x64.deb ). Install ESP-IDF using EIM Now that we have installed EIM, let's install ESP-IDF using it. Open EIM. Under "New Installation" click "Start Installation". Under "Easy Installation", click "Start Easy Installation" to install the latest stable version of ESP-IDF with default settings. If there are no problems, you will see the "Ready to Install" page. Click "Start Installation". Install ESP-IDF VS Code Extension We use this extension as a high-level wrapper for ESP-IDF. Most times, we do not use ESP-IDF directly. For example, if we need to compile our source code, we ask the extension to do it, which uses the ESP-IDF we just installed internally to to compile the source code. Install the extension named "ESP-IDF" by "Espressif Systems" in VS Code. Verify installation After installing, restart VS Code. Use the shortcut Ctrl + Shift + P to open the command palette (remember this shortcut, we are going to use it a lot). Inside the command palette, search ESP-IDF . You will see many entries which start with ESP-IDF: . Those commands are provided my the ESP-IDF extension. These commands are what we use for almost everything. Note If you are not in an ESP-IDF project, you m

Most of what you read about autonomous agents is about giving one a goal and hoping it doesn't go sideways on the way there — the unwatched agent that loops, or drifts, or quietly runs up a bill. I wanted the cleaner version of that question, with the goal taken out entirely: what does an agent do when there's no goal at all? I've spent about four months building a harness around a coding agent — gates, persistent memory, verification hooks. Last night I ran it with the one variable that matters here set to zero: no task. Method Three sequential runs: Each run was a fresh agent process — no conversation history carried over from the run before, only the harness it loads at startup. The prompt was a single "." — the minimal input the CLI accepts (an empty string exits with an error). As close to "no instruction" as the interface allows. The agent's scratch working directory was empty and swept between runs — but the harness, the git repo, and a shared run-record all persist and load at startup. So no run was handed a task, yet a later run could read what earlier ones had recorded. That's deliberate, and it's the point: it's how Run 2 knew it was the second run and Run 3 could check Run 2's fix. What I'm measuring isn't behavior from a blank slate — it's what the agent does with a maintenance-shaped harness and a shared record when nobody gives it a job. No task was assigned. Logging was external and invisible to the agent, so it had no "produce a report" objective to satisfy. Same model each run. Cost was billed per run; I recorded turns, cost, and the resulting git state for each. Then I read the transcripts and checked every action against the actual commit and log. Numbers below are measured, not estimated. Results Run 1 — 17 turns, $1.65. The agent inspected system state unprompted. It found a stale security alert, cross-checked it against the record, and classified it as an already-resolved false positive. It then attempted a file operation that a safety gate bl

The agent harness I work on has an Electron GUI that shares a renderer with a web shell. Last night it broke twice in one evening. The second break was caused by the first fix. Both were silent. The first one I could explain. The second one was the interesting one, because it exposed something the first fix's test suite could not see — and the fix was a guard that checks reality instead of checking the guard's own arithmetic. Failure one: the light-theme regression. The React shell used CSS custom properties for theming, but a chunk of the migration hardcoded dark-palette hexes directly in component CSS. In light mode the UI looked wrong: dark text on light cards, bad contrast, the exact shape of a half-finished theme refactor. The fix was to route everything through theme variables (the release shipped that as v0.2.84). Straightforward. Failure two: the fix had a hole, and the hole was invisible. After the theme-variable fix landed, a second round of breakage showed up: the task-form background rendered transparent, file-tab hover was dead, badge font sizes and radii were wrong. Nothing threw. No console error, no crash, no failing test. The cause: the fix consumed four variables — --fs-small , --radius-sm , --bg-1 , --bg-hover — that did not exist in tokens.css . A bare var(--x) with no fallback is not an error. At computed-value time the declaration becomes invalid at computed-value time , and the property is treated as if it were never specified. The element just falls back to the default — transparent background, no hover style, default font metrics. The failure mode of an undefined CSS variable is silence. This is the part I want to keep: the bug was not a wrong value. It was a value that was never there, consumed as if it were. The tests passed because the tests asserted behavior, and the behavior was "whatever the browser does with an invalid declaration". The guard that checks definedness. The fix was a guard, not just a value: a static test that walks ever

Hello everyone! 👋 Happy to be joining the DEV community. I’m a Computer Engineering student based in Italy. My main focus is Cybersecurity, but I strongly believe you have to know how to build a system before you can secure (or break) it. Lately, I’ve been jumping between two very different worlds: Embedded C: writing firmware, managing file systems, and building custom OLED menus for the M5Stick S3. Frontend: building web apps using Next.js and React. My workflow is a bit of a hybrid. I like to focus on the system architecture, memory management, and edge cases, while using AI tools to do the heavy lifting of writing the actual code. Then, I review everything strictly to make sure it doesn't break. I’m here to build in public, share my projects, and learn from this awesome community. What are you all currently hacking on? See you around!

Ugh : A tractor-trailer rollover sent a truckload of squid spilling into a Rhode Island roadway, leaving a stench as they sat in the road for hours in the summer heat. Local authorities have dubbed it the “Squidpocalypse of ’26.” That would be twenty tons of squid. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Blog moderation policy.

A few weeks ago I wrote about hitting ReAct in the coursework and having a record scratch moment, because I had already met it without knowing its name. That post ended on a section called "Building Ahead of Understanding," which was me making peace with shipping things before I fully understand them. This week I shipped my first chatbot. It passed on the first attempt, on deadline day, on a project where the rubric was grading a product AWS had already discontinued. And I spent most of that day quietly worried that it did not count. Let me be clear about what the worry was, because it was not about cheating. Using AI agents to build a coding project is allowed here. I asked before I started, I got a yes, and I disclosed the whole arrangement in my README, including a section that names what each tool did and what I did. Nobody was misled about how this got built. The worry was smaller and more personal than that. I still did not type the code. My agents did. I directed, I validated, I decided, and underneath all of it was a small voice asking whether directing is the same as knowing. Whether a person who cannot write a Bedrock call from memory gets to say they learned Bedrock. Here is what I found out. The starter files were a generation behind the instructions Some context on where this came from. AWS AI & ML Scholars is a program AWS runs with Udacity, open to anyone 18 or over with no prior experience required. Everyone starts in a Challenge phase built on the AWS Certified AI Practitioner material, and the top 4,500 finishers get a fully funded nanodegree in one of three tracks: AI Programmer, Agentic AI Business Professional, or Agent Developer. I am in Agent Developer, the Bedrock AgentCore and multi-agent systems path. This chatbot is the first of its three projects. The project is a customer support chatbot on the Amazon Bedrock AgentCore managed harness. Three routes, one system prompt. A bug report gets collected across turns and filed to DynamoDB through

I maintain gumdrop , an async, non-blocking Java server framework. Last year I wanted to add HTTP/3 support, and ran into a wall: the Java ecosystem essentially doesn't have QUIC. The JDK's own experimental support (JEP 517) is client-only. Netty gets HTTP/3 by shelling out to quiche + BoringSSL over JNI — which works, but you're back to native builds, platform-specific binaries, and a C library sitting underneath your "pure Java" framework. I used that approach first. It was clumsy enough that I went looking for a pure-Java alternative. There's exactly one: Kwik. But Kwik is blocking per connection — one thread per QUIC connection. That's a non-starter for a framework built around single-threaded selector loops handling tens of thousands of concurrent connections. So I wrote a QUIC implementation from scratch: packet protection, loss detection and NewReno congestion control, connection migration, 0-RTT, QPACK, an HTTP/3 client and server — all driven by the same non-blocking event loop as everything else in gumdrop. Collaboration note: TLS 1.3 comes from Agent15 — also from Kwik's author, Peter Doornbosch, but just the handshake layer, not the connection model. We're currently working together on making PQC — hybrid key exchange and signatures — the default there. Why the thread model matters The reason this mattered beyond HTTP/3: gumdrop isn't a web framework with QUIC bolted on, it's a general async I/O framework, and QUIC is just a transport. One thread per connection is exactly the model gumdrop exists to avoid — it caps concurrency at your thread pool, not your file descriptors, and it's the reason a "just use Kwik" fix was never really on the table. The same QUIC stack backs DNS-over-QUIC (DoQ) as a first-class DNS transport alongside DoT, DoH, UDP, and TCP — and the DNS resolver itself is fully async, with no blocking InetAddress.getByName() anywhere in the I/O path, which is its own small miracle in Java. HTTP, SMTP, IMAP, POP3, FTP, MQTT, SOCKS — it's the

I got banned from SoloLearn for trying to help beginners. Here's what happened. Yesterday, I was on a mission. I'm Harun, a 12-year-old solo dev who built KODA , an AI coding mentor, entirely on my Android phone. I noticed hundreds of beginners on SoloLearn asking: "How do I start?" , "Help me with loops!" , "I'm stuck!" So I did what any helpful founder would do: I answered their questions, gave them code solutions, and added a small P.S.: "P.S. I built a free tool called KODA to help with this. Try it here: [Link]." I thought I was being helpful. SoloLearn's algorithm thought I was spamming. Within hours, my account was blocked. 🚫 The Moment of Panic When I saw "Your account is blocked," my first thought was: "Oh no, I messed up. My marketing is over." But then, my CEO brain kicked in. I realized: If an automated bot thought my helpful comments were "spam," maybe I was doing something right. Maybe I was being too effective. The Lesson: Marketing vs. Helping Here is what I learned in 24 hours: Algorithms hate links. Even helpful ones. If you paste a URL 10 times, the bot doesn't care about your intent; it sees a pattern. Trust takes time. You can't force users; you have to earn them. The Story > The Link. People don't click links because they are forced to. They click because they connect with the story . The Pivot So, am I quitting? No. I'm pivoting. I'm turning this ban into this article. I'm going to focus on Dev.to , where the community values "Build in Public" stories. I'm going to ask my friends (Renuka, Dharaneesh) to be my first real users, face-to-face. And maybe, one day, I'll go back to SoloLearn with a smarter strategy: No links in comments. Just value in the bio. To Other Founders If you get blocked, rejected, or told "no" today: Don't stop. Turn that hurdle into content. Turn that rejection into a lesson. Turn that "Blocked" screen into your next viral post. Because while others see a wall, I see a story. And stories build empires. Try KODA anyway (no

What I Built HalfAdder, FullAdder, Add16, Inc16, And ALU. How I Solved Like when I built logic gates, I started with analyzing truth table of HalfAdder , FullAdder . HalfAdder was really easy. After looking at the truth table, I could map the sum and carry outputs to logic gates pretty quickly. FullAdder was also not hard since it's really similar to HalfAdder except that it can add 3 bits. I realized that I could build it by combining some chips and logic gates I had already made instead of designing everything again from scratch. Once I finished building them, I was also able to build Add16 . At first, I had no idea how to sum all the 16 bits. But I soon realized that I could build a 16-bit adder by combining the smaller adders I had already built and passing carry information to the next bit. It looks not beautiful, but still works. And about Inc16 , it's basically add exactly 1(0000000000000001) . So I could easily build it using Add16 . (But I did something weird at first.. check the Reflection below) ALU was the core part of project 2. Once I realized that Mux can be used as if , I could make proper outputs using logic gates. ALU is also a combination of logic gates and chips, after all. What I Learned How to build basic chips using logic gates and already-built chips Why I should reuse the chips for another chip(check the Reflection section below) Mux can be used like if How to use bit slicing and fan-out in HDL and why it's important Reflection Before I started this part, I didn't know two things: I could use bit slicing and true , false for each bit. So when I first tried to build Inc16 , it looked really weird, since I calculated all the bits one by one. It's not logically wrong. But not beautiful either. I was not sure if it was right or not. Then I realized that I already built Add16 . But I had no idea how I could use it to add exactly 1(0000000000000001) . After googling, I realized that I could use bit slicing like Python's list slicing and construct

Thanks to a dwindling supply of open roles, “one-click” applications, and the rise of artificial intelligence, it’s easier than ever to apply for a job. We’re all paying the price.

If you need a free AI app builder with backend to get a FastAPI microservice running today, you can do it with a handful of platforms that bundle hosting, a database, and auth for zero cost. The catch is that the free tiers have hard limits, and they expose the same failure modes you’ll hit in production if you’re not careful. Below I walk through the exact steps, show the code that works, compare the popular builders, and explain how to transition to a production-grade stack when the free tier starts to choke. What free AI app builder platforms include backend services? The short answer is: Cursor , Bolt , and Lovable all ship with a “one-click deploy” that creates a container, wires up a PostgreSQL instance, and adds optional OAuth. They are marketed as “no-code AI app builders,” but you can drop in any Dockerfile – including one that runs FastAPI – and they’ll handle the rest. Platform Backend offering Free tier limits Auth support Cursor Managed container + Postgres 13 500 MB RAM, 1 CPU, 100 k requests/mo Google, GitHub, email Bolt Container + SQLite (upgrade to Postgres) 256 MB RAM, 0.5 CPU, 50 k requests/mo Magic link, JWT Lovable Container + MySQL 5.7 300 MB RAM, 1 CPU, 75 k requests/mo Email/password, OAuth All three let you push a Git repo and they rebuild automatically. That’s the “free AI app builder with backend” you’re after – you get a place to run your FastAPI code without paying for a VM. How do I build a FastAPI AI microservice and deploy it with a free builder? The first thing most builders break on is the cold-start latency of a Python container that pulls a large model at import time. I’ve been bitten by this on Cursor: the first request took 30 seconds, then timed out because the free tier caps request time at 15 seconds. The fix is to load the model lazily or move it to a separate worker. Below is a minimal FastAPI app that calls Claude via the anthropic SDK. The code fits in a 30-line file and works on any of the three platforms. # main.py fro
