Olá pessoal. Este vídeo ensina a calcular senos em C usando a Série de Taylor, sem recorrer à biblioteca <math. https://youtu.be/-V3icd6VLJY Este é um projeto de extensão da USP de São Carlos (BCC-ICMC). Agradeço quem puder responder ao formulário que está na descrição! (Já tentaram calcular senos sem usar ?)
Ride History: Tracking Every Completed Trip On the backend, the API queries Supabase for every ride tied to the user's Google ID, filtered to only completed rides and ordered newest-first: There's no date filter and no row limit -- it returns every completed ride the account has ever taken. On the mobile side, each ride renders as a card showing the date, route, pickup time, and the matched rider
TL;DR We had a single-tenant Angular + .NET 10 SaaS where every row was scoped by UserId. To support firms (multiple lawyers sharing data), we needed multi-tenant workspaces — but rewriting every query was off the table. EF Core's HasQueryFilter made it possible to flip 9 tables to multi-tenant in a single weekend, with zero query call sites changed. Here's the pattern. I'm building NeoJurídico,
If you've worked with Entity Framework Core in real-world architectures, you've probably written commands like this: dotnet ef migrations add InitialCreate \ --project src/MyApp.Infrastructure \ --startup-project src/MyApp.Api \ --context AppDbContext And maybe this worked fine... Until your architecture started growing. Suddenly you have: multiple APIs worker services separate infrastructu
A defaced website is a curious problem. It's loud — anyone visiting the page can see something is wrong. But it's also quiet from a server's perspective: HTTP returns 200, your uptime monitor is happy, your TLS cert hasn't moved, and the CMS logs show a "successful" content update from a legitimate-looking session. The signal is on the rendered page, not in the metrics. I run a site at hi3ris.blue
You just ran a dependency scan and the report shows 133 vulnerabilities. 34 are Critical. 68 are High. The dashboard is red, the backlog is exploding, and every item looks urgent. The engineering team asks the obvious question: where do we start? This is where vulnerability remediation prioritization matters. Without a clear framework, teams either panic and chase the loudest CVE, or they ignore t
We talk a lot about “data-driven decisions”, but that usually hides three separate layers: Data itself (events, transactions, logs, etc.). Database structure (schemas, constraints, relationships). Insights on top (from SQL, AI copilots, BI tools, notebooks). My current interest is in that middle layer: using real-world database structures as a playground to practice database insights: Understan
Vendredi matin, 9 h 15. Françoise est dans son cockpit — trois écrans, à gauche l'Excel-pointeuse qu'elle tient à jour depuis quinze ans, à droite Sage, et au milieu Rembrandt depuis trois semaines. Sa tasse à la main, celle avec sa tête imprimée dessus que quelqu'un lui a offerte à Noël. Elle pivote sur sa chaise et me lance depuis son bureau : « Michel, combien on a d'inscrits pour la rentrée, d
