User bought some stock but the network is slow. There is no immediate feedback, so out of frustration, they tap the Buy button several times. A few seconds later, multiple orders are matched. Have you ever got into this situation? Disabling the button in the UI helps, but it isn't guarantee. UI
Minutes and tokens per iteration - and why an expensive one is a defect of the text, not of the executor. 👋 I'm Anton - a software engineer working mostly in PHP/Symfony and Go, currently carving a live PHP monolith into Go services. Earlier parts of this series were about how small a unit of wo
Git's default revert message is useful, but it does not fit nicely into a Conventional Commits history. Given this commit: feat(email): add send tool git revert generates: Revert "feat(email): add send tool" I wanted: revert(email): add send tool So I built conventional-r
Five silent bottlenecks that turned a 400ms API into a 4.2s crawl No deploys. No schema changes. No new integrations. Just a scheduling and resource-planning SaaS with 40k users watching its p95 response time climb from 400ms to 4.2 seconds over six months. Nobody could point to a cause, because t
I’m currently learning PHP and working on a PHP project. I want to properly manage my source code, track changes, and keep my project backed up online. For a beginner, would you recommend using Git + GitHub, or are there better tools for managing PHP projects? What tools and workflow should I lear
I rented three servers this afternoon, one in Frankfurt, one in New York, one in Singapore. I gave the addresses to nobody. They are not in DNS, not in a certificate, not committed anywhere, not pasted into a chat. The only systems that knew these machines existed were the ones I rented them from.
On our architecture diagram, two systems exchanged data through an integration. In reality there was a third component between them, and it was a workbook on a finance analyst's drive. Her part of the process took about forty minutes each month. Export a file from the first system, open the workboo
The title literally means: "I have parallel dataloaders, GPU kernels and a high-performance computing programming language all expressed in a framework with 1400 lines of code". You may run the ResNet-18 benchmark yourself (github.com/NoSavedDATA/Neve_benchmarks) I released the Neve programming la
If you are learning IoT (Internet of Things), building an ESP32 project is one of the easiest ways to understand how sensors, microcontrollers, internet connectivity, MQTT, and cloud dashboards work together. In this beginner-friendly tutorial, we'll look at the architecture of a simple ESP32 IoT p
In e-commerce, a user clicks an ad, lands on a product page, adds an item to cart, and checks out in five minutes. Standard browser pixels handle this without breaking a sweat. In fintech, forex, crypto brokerages, and prop trading platforms, the conversion lifecycle looks completely different: A
In my last article I described the margin spiral — leverage feeding on itself until a correction becomes a crash. This one is the same loop, one level down, in the plumbing of the market. The actors aren't leveraged funds this time. They're the market makers who are supposed to keep prices smooth. A
You have a static page with a contact form. You want what people write in it to arrive in your inbox. You search, and half the answers say mailto:, the other half say "use a backend", and nobody tells you which details will bite you at 2am when a customer says they wrote and you never got it. Here
MCP Python SDK extension method collisions are configuration defects, not runtime edge cases. If two extensions claim the same method—or one claims a core MCP method—the server should reject that setup before it accepts a request. I prefer making method ownership an executable contract so registrati
Introdução O Observer Pattern (Padrão Observador) é um padrão de projeto comportamental, ou seja, ele trata de como os objetos se comunicam e distribuem responsabilidades entre si em tempo de execução — diferente dos padrões criacionais (que tratam de como objetos são instanciados) ou estruturais
I set out to benchmark Pingora 0.9.0 — the Rust proxy library Cloudflare runs at its edge — against nginx, in the environment I actually care about: a small pod with a CPU limit, two vCPUs, everything in containers so no number leans on the host. I wrote the simplest possible reverse proxy with Pin
The Problem You're debugging a connectivity issue. ping works fine, but curl times out. The usual approach: Run traceroute with ICMP - looks fine Run traceroute with TCP - dies at hop 6 Manually compare each hop Finally identify the firewall/ACL What if you could see this in one command?
Dockerizing ROS 2 and AI Robotics Applications for NVIDIA Jetson Package your ROS 2 application and AI dependencies into reproducible containers. The tutorial covers Dockerfile structure, NVIDIA container runtime concepts, device access, ROS networking, persistent configuration, logging, and depl
Building a Vision-Language Robot with Jetson + ROS 2 Combine camera perception and language understanding into a robot pipeline. The robot receives a visual scene, extracts useful structured information, combines it with a user instruction, and produces a validated task plan for ROS 2 execution.
Edge LLMs on NVIDIA Jetson: Building an AI Assistant for Robots Build a robot assistant architecture in which an edge language model interprets natural-language requests but does not directly control actuators. The LLM produces structured intents; a deterministic command layer validates permissio
In my previous AWS projects, I worked with services such as DynamoDB, Lambda, API Gateway, S3, IAM, and Terraform. This time, I wanted to build something a little closer to a real production architecture. Instead of processing an order synchronously inside an API request, we'll build an event-driv
