This site's old MVC app used Hangfire with its own database. The API that replaced it uses two BackgroundService workers and a bounded Channel. Here is what each job became, the code, and what I gave up.
Crawled vs Discovered - currently not indexed, with this site's own Search Console data: 63 of 219 URLs, which pages landed in each status, and what Request indexing did for 12 of them a day later.
'Error unprotecting the session cookie' in ASP.NET Core means the Data Protection keys were lost. What I reproduced, the different messages each cause produces, and the Program.cs fix for IIS.
LinkedIn's 'Content credentials label added' and Facebook's 'AI content' label both come from a signed C2PA manifest hidden inside the file. I tested the same ChatGPT image with and without it - here is what triggers the CR icon, what it shows, and how it is removed.
'X' scripting variable not defined - what sqlcmd is doing with $( in your strings, what I tested (the script keeps running with exit code 0, and environment variables rewrite your data silently), and when to use -x, CHAR(36) or single quotes.
'UPDATE failed because the following SET options have incorrect settings: QUOTED_IDENTIFIER' - why the same statement works from your app and fails from sqlcmd, what I tested on SQL Server 2022, and the one-line fixes for scripts, sqlcmd and stored procedures.
PHP2Shell is two critical bugs in PHP itself that allow remote code execution before your code even runs. How they work, how AI-assisted researchers found them, how the disclosure leaked, how PHP fixed them, and whether AI is the real danger.
DeepSeek Harness (dsh) is DeepSeek's open-source agent harness, built so that everything - even the agent loop - is a plugin. I installed it and took the web profile apart: here is what an agent harness is, how to run dsh, what its 193 plugins do, and what to watch out for.
AI reverse engineering now means an agent like Claude driving Ghidra or IDA through MCP. Here is how the tools fit together, what a real session looks like, what the first benchmark says, and the setup problems and limits nobody puts in the README.
Each issue in our own PageSpeed report and exactly what we changed - code splitting, the fade-in that hid our headline, analytics on interaction, two fixes that backfired - plus e-commerce speed and security headers.
Our own benchmark of gzip, Brotli and zstd (body size, requests per second, CPU), and the Cloudflare settings this site runs: what is on, what is off, and what a shop must never cache.
The page loads with no styling and the console says ChunkLoadError. The build is fine and the files are on the server. The HTML asking for them is three hours old and came from your CDN, and it is still naming the chunks from the previous build.
