What is socket activation in systemd? 🤔
One of the key applications of systemd is to start and manage long-running background processes - daemons. Daemons are registered as systemd service units and typically start at boot.
However, if a service isn't needed immediately after boot and exposes a TCP or Unix socket API, it's more efficient to start it only when the first client connects. This technique is called socket activation.
The most fascinating part is how it's implemented - there is no magic, but you need to know the trick.
The listening socket is created as usual, but it's systemd itself that opens it. Once the first client arrives, systemd executes the daemon and passes it the socket's file descriptor. So the only "unusual" thing the daemon does is call socket.fromfd(SD_LISTEN_FDS_START) instead of creating a new socket itself.
Practice configuring socket activation for daemons with:

Happy hacking!

Smart code is needed only in a very small share of practical cases, such as performance optimizations of hot loops. The rest of the code must be easy to read, understand, debug and maintain. AI must be taught to generate simple code most of the time.

رجاء من السادة، لما تلاقي حاجة غبية بلاش تتفاعل معاها، يمكن الافضل كمان لو تعمل بلوك او ميوت للناس الي بتقول الكلام ده
ناس بتقول كلام استفزازي و بعدين لو دورت شوية بتلاقيهم شغالين قلاب، حسب الـظروف و كده، فا لو لقيت حاجة مش تمام عديها، علشان التفاعل ده بيعمل كذا حاجة
- ترويج للافكار المقرفة
- بتشجع الي بيقول الكلام ده انه يقول اكتر
- بتخلي ناس اكتر تتفاعل علشان يعني انت مش لوحدك و كده

ان شاء الله هيكون في محاضرة مجانية عن ازاي نبني Decision Layers for AI Agents باستخدام Jev يوم الخميس ١٥ اكتوبر.
تقدر تحجز بشكل مجاني من الرابط اللي في التعليقات!
I am hosting a free live workshop on Building Decision Layers for AI Agents with Jev.
A lot of agent workflows still use general-purpose LLMs for small decisions that do not require generated text. Things like:
→ Which model should handle this request?
→ Is this tool call risky?
→ Is this retrieved result relevant?
→ Should the agent continue, stop, or ask for human approval?
In this workshop, I will explain how Jev can be used as a decision layer around an AI agent, where the model handles bounded semantic judgments while normal code keeps control over the final action.
We’ll cover practical use cases including:
- model routing
- tool-risk gating
- retrieval and relevance checks
- verification and supervision
- escalation and human approval
I will also walk through a hands-on implementation and share results from my own experiments comparing Jev with a general-purpose LLM on latency, cost, and decision behavior.
The goal is not only to understand how Jev works, but also where it actually fits inside an agent architecture, when deterministic code is still better, and when you still need a full reasoning model.
The workshop is completely free, but seats are limited.
Book your seat from the link in the comments.
