Common Web Application Technologies

Introduction Modern web applications are rarely built with a single technology. A typical application combines a web server, a programming language, a framework, a database, data formats, and backend services to deliver its functionality. For anyone learning web application security, it’s important to understand these technologies at a basic level—not only to recognize them, but to und...

Holehe Alternative in 2026: Modern OSINT Email & Username Intelligence with user-scanner

When mapping digital footprints, security analysts and open-source intelligence (OSINT) practitioners rely heavily on registration checkers. For years, single-purpose utilities like Holehe were the industry standard for checking email recovery endpoints. However, modern target profiling requires deeper correlation, higher concurrency, and cross-platform pivoting across both emails and usernames. ...

Auto mode is now Claude Code's default: what the classifier approves, and how to switch back

Starting today — August 14, 2026 — auto mode is the default permission mode for new Claude Code sessions on Pro, Max, and Team plans. If you've never touched your permission settings, your next session starts with a one-time switch prompt, and after that Claude runs most actions without asking you first. That's a real behavior change, not a UI tweak. This post covers what the classifier actually ...

I Benchmarked My Homelab Memory Stack: Hybrid Search + Local Reranker Took LoCoMo from 63% to 80%

Pure vector search got my agent memory stack to 63% on LoCoMo. Adding a sparse retriever and a reranker that runs on a card I already owned pushed it to 80%. The accuracy came from a stage that adds maybe 40ms per query, and the queries it fixed were exactly the ones I cared about: specific dates, error codes, and "who said what in which session" needles buried in months of conversation history. ...

Detecting SQLite Full Table Scans in Node.js

Back in July, Aaron Patterson wrote about detecting full table scans with SQLite. The trick is that you don't need EXPLAIN QUERY PLAN for this. SQLite already keeps a per-statement counter of how many rows it walked during a scan, and you can read it after the query runs. If the number is greater than zero, that statement scanned. One day later, Kevin Gibbons opened an issue on nodejs/node asking...

I Built an Open-Source project. It Became the Official MailChannels JS SDK

How an independent open-source project grew into a full TypeScript SDK and was eventually adopted by MailChannels. Sometimes, open-source projects start with a very small problem. You build something because you need it yourself, publish it because you think someone else might find it useful, and then keep improving it simply because you enjoy building software. That was the story behind mailch...
