Introduction Learn how to properly use a JsonConverter, along with property and global setup for converters. Before getting started, the converter is intentionally simple. The focus here is proper planning for the data for a specific task, like importing data from a JSON file into a database, in this case, properly formatted.

6. Engenharia de Prompts: de Zero-shot a Retrieval Augmented Generation

A mesma pergunta feita a um modelo de linguagem pode gerar uma resposta genĂ©rica, uma resposta certeira ou uma resposta completamente errada — e a diferença, na maioria das vezes, nĂŁo estĂĄ no modelo, estĂĄ em como o prompt foi construĂ­do. Engenharia de Prompts Ă© a disciplina de projetar a entrada de um LLM (instruçÔes, exemplos, contexto, formato esperado) para extrair o resultado mais Ăștil e confiĂĄvel possĂ­vel, sem alterar um Ășnico parĂąmetro do modelo.

7. How to choose a used FortiGate firewall (without getting burned)

Used enterprise firewalls are one of the best deals in homelab and small-office hardware. A FortiGate 100F that retailed for €4,000 can be had for €400–600 on the secondary market. But unlike a used switch or server, a firewall has pitfalls specific to the platform that can turn a bargain into a headache. This guide focuses on FortiGate because Fortinet dominates the SMB/branch market — which means the widest used supply — but most principles transfer to other NGFW vendors. Why FortiGate specifi...

8. Overpatch and Heapjack: Two Techniques for Bypassing Codex's Write Restrictions and Escaping Its Read-Only Sandbox

1. Basic Information Original Title: Escaping the OpenAI Codex sandbox, twice Source: Accomplish AI Published: 2026-09-15 Updated: None Severity: High Basis for Severity: Researchers verified Overpatch, which writes outside the workspace using workspace-write, and Heapjack, which executes host commands from the strictest read-only mode without an approval prompt. Conditions were also shown where simply opening a malicious repository and asking a question is enough. Both issues were patched withi...

1. Basic Information Original Title: npm 'btree' Malware Campaign Affects Millions of Downloads, No Need for Install Script Source: Checkmarx Zero Publication Date: 2026-09-17 Update Date: None Severity: High Severity Justification: The malicious npm packages do not use install scripts and instead launch a loader from within a normal library method. Checkmarx states indexed-btree reached nearly 2 million weekly downloads, and confirms capabilities to exfiltrate host information, resolve C2 desti...

10. When Your Impact Is No Longer Measured in Pull Requests

I recently came across a post about the transition from Senior Developer to Tech Lead, and it got me thinking about something I've been experiencing myself: how much your definition of productivity changes when you move into technical leadership. For most of my career as a developer, being productive was pretty easy to recognize. I could look back at my week and see the features I implemented, the bugs I fixed, the PRs I opened or reviewed, and the technical problems I helped solve. There was al...

11. Architectural Breakdown: i built a green blob that lives on my desktop. now it has feelings.

# I Built a Green Blob That Lives on My Desktop. Then It Stopped Being Cute. ![Architecture Diagram](https://image.pollinations.ai/prompt/high+performance+cloud+systems+i+built+a+green+blob+that+live+round+2?width=800&height=400&nologo=true) Three weeks ago, my desktop blob stopped being a cute screensaver. It started ignoring my "pet" interactions. When I clicked it, it drifted away. I checked the logs. Valence score: negative zero point nine seven. Arousal spike: zero point nine five. The blob...

12. Unreal C++ Course Chapter 109

In this chapter we set up the enumerations for the player character's equip state, in my case AEchoCharacter. I declared my enumerations in a separate header file CharacterState.h which can also be used for other states besides equipping items: Alive/Dead, Climbing/Swimming etc. I decided to specify my enum encapsulation as ECharacterEquipState. Although I didn't fully agree with making the character variable private, I went along and will do all my state logic under the AEchoCharacter hood, usi...

13. I Built a 100% Free AI Toolbox with No Sign-Up (Here's How)

TL;DR: I built MagicKit — a free AI toolbox for image generation, AI writing, and video making. No sign-up, no API key, no paywall. The whole thing is open source on GitHub. Why I built this Every AI tool these days wants you to sign up, hand over an API key, or subscribe before you can even try it. I wanted the opposite: open the page and just create. So I spent a few evenings building MagicKit — three tools in one page: đŸ–Œïž AI Image Generator — text-to-image with the FLUX model, multiple aspect...

Every one of our Actors is HTTP-only — no Puppeteer, no Playwright, no headless Chromium in production. We say this is faster and cheaper. This post is the measurement, not the assertion. The setup Same target, two approaches, same box (1 vCPU / 2 GB RAM, the machine this whole business runs on): HTTP-only: GET https://allbirds.com/products.json?limit=50 — Shopify's public, unauthenticated catalog endpoint (the same one shopify-products-scraper uses).

It progresses from a toy example into a working allocator, covering the problems and design decisions along the way, as well as benchmarking the final product.

2. Dune: Awakening’s Massive New Update Is Perfect For Parents Or Single-Player Fans, And It’s At Its Lowest Price, Too

I have over 50 hours in Dune: Awakening. The soft-MMO, mostly survival-centric game became one of my favorite games of last year. However, as a parent—and generally busy guy—playing Dune: Awakening has become less fun and more chore-inducing. The eventual endgame of fighting other players also took away some of what made Funcom’s take on Arrakis so interesting. Over a year later, with plenty of updates under its belt and the massive new 1.5 update, Dune: Awakening isn’t just better than ever; it...

3. Orbitals Is An Antidote For Hazelight’s Miserable Characters

Something core to Orbitals stuck out to me as I played the Switch 2 exclusive. Compared to the similar co-op games from Hazelight Studios, the major difference in Shapefarm’s two-player 3D platformer was that the two main characters, Maki and Omura, actually seemed to enjoy each other’s company. While that might seem like an inconsequential detail, it was actually a breath of fresh air after sitting through Hazelight's co-op hits A Way Out, It Takes Two, and Split Fiction, which all centered on ...

5. Kingdom Come: Deliverance 2 Is At A Royally Great Discount, So What Art Thou Waiting For?

When I first booted up Kingdom Come: Deliverance 2, I wasn’t too sure what to expect. I hadn’t played the first game (I know, I know, put down the pitchforks!), and, as someone who prefers fantasy over medieval settings, it wasn’t my usual cup of tea. However, it quickly became one of my favorite RPGs ever, as I watched Henry go from a ragtag blacksmith’s son to a strong knight once again. Now, you can grab it at its lowest price ever. Like many of the best RPGs ever made, Kingdom Come: Delivera...

6. The Frustrating Mystery Of Who Makes Nintendo Games

Whenever a Nintendo game gets a splashy reveal in a Direct, my immediate hype takes on a few forms. I’ll replay the trailer at least once, then I’ll start going frame by frame. I scour Nintendo’s websites for concrete information, then I read up on Reddit comments and theories to see what other people noticed that I might have missed. And then, I watch the trailer yet again. But almost every single time, my brain lands on the same question: Who the hell made this thing? The most recent catalyst ...

7. Indie Dev Says “AI” Voice In His Game Was Actually His Wife

Someone playing Refractive Entertainment's recently released action-RPG Luminary for less than an hour accused the team of using AI for the game's only voiced character. The player said the voice "killed it" for them. There was just one problem: It wasn't AI. It was actually the developer's wife doing her first-ever voice acting gig. Refractive Entertainment launched Luminary into Steam Early Access on August 11. It's a resource-gathering action-adventure sandbox with an art style that's giving ...

Brynn Putnam and Tristan Walker have already done something that most founders only dream about: created companies so compelling that bigger outfits bought them.
