Stop Building Agent Memory. Your Agent Doesn’t Need It.

Stop Building Agent Memory. Your Agent Doesn't Need It.

Last week I looked at my Redis dashboard and realized something: 4 out of 5 agent memory databases had zero queries in 7 days. I spent three weeks building them. They sit there, collecting dust, like unused gym memberships.

The agent uses exactly one memory type. The other four? Never queried. Never read from. Never written to.

This is not a post about how to build agent memory. This is a post about why I built the wrong thing, and what I learned when I stripped it all away. Earlier, I wrote about how my AI agent kept breaking — this memory experiment was part of that same journey.

Claude Sonnet 5: The First Agentic Model That Can Code and Use Tools Like Opus

by
Susiloharjo

Claude Sonnet 5 was just released by Anthropic with an ambitious claim: this is the most agentic Sonnet model ever. It can make plans, use tools like browsers and terminals, and run autonomously at a level that only large, expensive models could handle a few months ago. What’s interesting is that Sonnet 5’s performance is … Read more

TLS 1.3 Features. What Changed From TLS 1.2. And Why It Matters

by

TLS 1.3 shipped in 2018 as RFC 8446. It is the biggest overhaul of the TLS protocol since SSL 3.0 in 1996. Five years after release, TLS 1.3 now protects over 70 percent of HTTPS connections. The upgrade is not incremental. It changes how the handshake works. It removes broken cipher suites. It mandates forward secrecy. And it makes the protocol faster.

This post covers what TLS 1.3 adds. What it removes. And why the changes matter for anyone running a server or building a client.

SSL Is Dead. TLS Runs The Web. Here Is What Actually Encrypts Your Traffic

by
Susiloharjo

Every HTTPS connection on the modern web uses TLS. Not SSL. The padlock icon in browsers still says SSL. Hosting providers sell SSL certificates. Devops teams talk about SSL termination. But SSL has been dead since 2015. What actually protects traffic is TLS 1.2 or TLS 1.3.

This distinction matters. SSL and TLS are not the same protocol. They have different security properties. Different handshake flows. Different cipher suites. One of them has known vulnerabilities that attackers can exploit.
