Do you guys actually use AI to code or am i just overthinking this?



I think I'm starting to realize how normal it’s becoming to lean on AI for coding. Tools like Cursor, Windsurf, Continue, all that, are just part of the workflow now. even our prof was cool with it as long as we can explain what the code is actually doing.

I tried Cursor for the first time and honestly it was nice. something that would’ve taken me hours turned into writing a few prompts and fixing tiny mistakes. But it feels like i’m skipping the “learning” part.

I've been mixing in other stuff too Aider, GPT Pilot, even Cosine here and there just so i don’t lose track of how files connect when a project gets messy.

I think i’m just trying to figure out the balance. are we supposed to fully embrace these tools or use them sparingly so we actually learn? how are you all handling this?

Moved from Service Desk to DevOps and now I feel like a complete imposter. Need advice.

Hey everyone,

I really need some advice from people who’ve been in this situation.

I’ve been working in Service Desk for about 3 years, and somehow I managed to crack a DevOps interview for a FinTech startup. It felt like a huge step forward in my career.

But now reality is hitting me hard…

The team has started giving me an overview of their tech stack, and honestly, it’s stuff I’ve only heard of in videos or blogs. Things like CI/CD, AWS services, Terraform, Docker, pipelines, monitoring, etc. I understand the concepts, but I’ve never actually worked with them in a real environment.

I’ve never SSH’d into a real server, never used a real AWS Console, nothing. And now I’m feeling very small, like I’m not supposed to be here.

They think I know a lot because I interviewed well and answered most of the questions confidently. But internally I’m panicking because I don’t want to embarrass myself or let the team down.

I’m not trying to scam anyone, I genuinely want to become good at DevOps, but the gap between theory and real-world work feels massive right now.

So my question is:

How do I prepare quickly so I don’t feel like an imposter on Day 1?

What should I practice?

What projects should I build? How do I get comfortable with AWS, Linux, and pipelines before actually joining?

Any guidance from people who made the same transition would mean a lot. 🙏

TLDR: Coming from Service Desk with no real hands-on DevOps experience (no AWS, no SSH, no pipelines). Cracked a DevOps interview but now feel like an imposter because the tech stack is way beyond what I’ve practiced. Need advice on how to prepare fast and not freeze on the job.

Early feedback wanted: automating disaster recovery with a config-driven CLI.

I'm building a CLI tool to handle disaster recovery for my own infrastructure and would like some feedback on it.

Current approach uses a YAML config where you specify what to back up:

# backup-config.yaml
app: reddit

provider:
name: aws
region: us-east-1

auth:
profile: my-aws-profile
# OR use
role_arn: arn:aws:iam::123456789012:role/BackupRole

backup:
resources:
- type: rds
name: production-databases
discover: "tag:Environment=production"
- type: rds
name: staging-databases
discover: "tag:Environment=staging"

Right now it just creates RDS snapshots for anything matching those tags.

\*\*Would love to hear:\*\*

\- Thoughts on the config design

\- What resources you'd want supported next

\- Any "this will be a problem later" warnings

We open-sourced kubesdk - a fully typed, async-first Python client for Kubernetes. Feedback welcome.

Hey everyone,

[Puzl Cloud](https://puzl.cloud/) team here. Over the last months we’ve been packing our internal Python utils for Kubernetes into **kubesdk**, a modern k8s client and model generator. We open-sourced it a few days ago, and we’d love feedback from the community.

We needed something ergonomic for day-to-day production Kubernetes automation and multi-cluster workflows, so we built an SDK that provides:

* Async-first client with minimal external dependencies
* Fully typed client methods and models for all built-in Kubernetes resources
* Model generator (provide your k8s API - get Python dataclasses instantly)
* Unified client surface for core resources and custom resources
* High throughput for large-scale workloads with multi-cluster support built into the client

Launch container on first connection

I'm trying to imagine how I could implement Cloud Run scale to zero feature.
Let's say I'm running either containers with CRIU or KVM images, the scenario would be:
- A client start a request (the protocol might be HTTP, TCP, UDP, ...)
- The node receives the request
- If a container is ready to serve, forward the connection as normal
- If no container is available, first starts it, then forward the connection

I can imagine implementing this via a load balancer (eBPF? Custom app?), who would be in charge of terminating connections, anyhow I'm fuzzy on the details.
- Wouldn't the connection possibly timeout while the container is starting? I can ameliorate this using CRIU for fast boots
- Is there some projects already covering this?

Company is starting on-call soon. What should I request from management? Money? Separate phone? etc...

For reference, I'm in the US, a salaried employee, and 100% remote.

We've been working on a greenfield project for a few years that is now just going live and it's going to require our entire department (not just my team) to be on-call.

I guess this is my chance to make some requests from management. Should I ask to be compensated for on-call? Should I ask for a separate phone? Should I pull out my contract and refuse to do on-call if it's not in writing?

Should I give my fiver dev my login to my hosting account?

So I am asking because I don’t know if it is safe to give the developer I hired my login with my personal information on the account.

He said “The work related to Dokan requires noscripting in the backend inside the custom files. This cannot be done from the WordPress dashboard. And for noscripting, the database also needs to be configured so without access to the database, how will the work be done?
And if I’m editing but I don’t have hosting permissions, then how will I insert the noscript?”

So I made him a database dev account on phpmyadmin, a cPanel ftp account, and an admin account on my Wordpress site for him but he said that he still needs my login. Is it safe/should I give him my login? He has 5 stars and 178 reviews on fiver and from Bangladesh.

From PSI to kill signal: logic I used so auto-remediation doesn’t kill good workloads

Last week I posted here about using Linux PSI instead of just CPU% for “is this box in trouble?” checks.

This is a follow-up: if you trust PSI as a signal, how do you actually act on it without killing normal spikes?

The naive thing I’ve seen (and done myself before) is:

if CPU > 90% for N seconds -> kill / restart

That works until it doesn’t. Enough times I’ve seen:

JVM starting
image builds
some heavy batch job CPU goes high for a bit, everything is actually fine, but the “helper” noscript freaks out and kills it. So now I use 2 signals plus a grace period.

Rough rule:

1. CPU is high (example: > 90%)
2. AND CPU PSI is high (example: cpu some avg10 > 40)
3. AND both stay high for N seconds (I use 15s) If any of these drops during the grace period, I reset state and do nothing.

Only if all three stay true for 15 seconds, then I:

look at per-process stats (CPU, fork rate, short jobs / crash loops)
pick the top offender
send kill to that one process

This avoids the classic “kill → restart → kill → restart” loop from pure CPU-based rules. Short normal spikes don’t keep PSI high for 15 seconds. Real runaway jobs usually do.

I wrote up the Rust code that does this:

read /proc/pressure/cpu (PSI)
combine with eBPF events (fork/exec/exit)
apply the rule above and choose a victim

Write-up + code is here: [https://getlinnix.substack.com/p/from-psi-to-kill-signal-the-rust](https://getlinnix.substack.com/p/from-psi-to-kill-signal-the-rust)

This runs inside Linnix (small eBPF-based tool I’m hacking on: [github.com/linnix-os/linnix](https://github.com/linnix-os/linnix)), but the idea is generic. Even a bash noscript checking /proc/pressure/cpu in a loop with a grace period would be safer than plain CPU > 90% -> kill.

Curious how people here handle this:

Do you use a grace period for auto-remediation (k8s, systemd, custom noscripts)?
Do you gate actions on more than one signal (CPU + PSI / latency / queue depth / error rate)?
Any stories where “CPU threshold → restart/kill” caused more damage than it fixed?

Beginner in AWS: Need Mock Tests and Project Recommendations

I’ve been learning AWS for the past 2-3 months, along with Terraform, Gitlab, Kubernetes, and Docker through YouTube tutorials and hands-on practice. I’m now looking to work on more structured, real-world projects - possibly even contributing to public cloud related projects to build practical experience.

I’m also planning to take the AWS Cloud Practitioner exam. Could anyone suggest resources or websites that offer mock tests in an exam-like environment? Also, any recommendations for platforms where I can find beginner-friendly cloud projects to build my portfolio would be greatly appreciated.

RSS Feeds - DevOps, Cloud, etc

Hey everyone!

Kind of a fun post here but wanted to refresh my Reeder app and do some spring cleaning. With the advent of so much this year between AI and all sorts of barely-working-great-ideas from Harvard MBAs, thought it would be nice to see what kinds of RSS feeds people use/watch regularly across a few topics:

* DevOps
* Cloud (AWS, Azure, GCP, whatever)
* Infrastructure tech like CDNs, WAFs, ALBs, etc
* Platform Eng like K8s, docker, etv.
* Programming, maybe fixated on IaC as a topic

Anyway, my feeds have been a mix of broken or just not great lately and though I'd ask the community.

Azure Engineer or SRE more future?

I am a fresh grad with 1 year working experience (including internship) as a backend developer. I am really interested in cloud and DevOps. I recently received 2 interviews: Azure Engineer and SRE. I wonder which path has more future ?

The Azure Engineer position basically focus on IaaS , deployment, write Teraform. They said might have chance to do cicd pipeline in future... I am wondering is it a good path to go for Cloud engineer/ DevOps engineer? Because they also mentioned that it is bery easy to pick up... I am afraid if this is just a simple deployment job. But they do mentioned that I will do the design infrastructure etc. and a lot of things to learn.

Or SRE better? Which path has more future?
Hope to seek opinions from you all ..🙏🏻

Is Continuous Exposure Management the true SecDevOps endgame?

We talk a lot about "Shift Left," but the reality is security findings often hit the CI/CD pipeline late, or they are generated by a vulnerability scanner that doesn't understand the context of the running application.

I'm looking at this idea of Exposure Management, which seems like the natural evolution of SecDevOps/SRE practices. It forces security to be integrated and continuous, covering the entire lifecycle: code repos, cloud configurations, deployed application, and user identity. The goal is to continuously assess risk, not just find flaws.

If you are running a mature SecDevOps pipeline, how are you ensuring that security findings from different tools (SAST, DAST, CSPM, etc.) are unified and prioritized to show a single, clear measure of risk, rather than just raw vulnerability counts?

Switching to product based company

Question on programming languages and switching to developer role

Just a general question. In the product based companies, does programming language based on oops matters or even go lang should be fine. Consider both interview and regular day to day work.
The thing is i have almost 15 yrs experience, never coded in my life and I recently picked up go language. I know it will take lot of time to develop skillset considering i will not have practical exposure. But still a few questions if anyone can help.
1) I know I can never match or atleast get an entry to maang faang or whatever. But will there a chance for other product companies.
I don't know how tougher will be struggle in their day to day works.
2) If in interviews, if I choose go language with no idea around classes or oops will that be a reject.
3) I know at this age, system design etc..is expected but again i dont think I can understand them unless I have practical exposure. But if I am ready to lower my designation will that be ok.

Transparently and efficiently forward connection to container/VM via load balancer

**TLDR**: How can my load balancer efficiently and transparently forward an incoming connection to a container/VM in Linux?

**Problem**: For educational purposes, and maybe to write a patch for liburing in case some APIs are missing, I would like to learn how to implement a load balancer capable of scaling a target service from zero to hero. LB and target services are on the same physical node.

I would like for this approach to be:

* **Efficient**: as little memory copying as possible, as little CPU utilization as possible
* **Transparent**: the target service should not understand what's happening

I saw systemd socket activation, but it seems it can scale from 0 to 1, while it does not handle further scaling. Also the socket hands off code felt a bit hard to follow, but maybe I'm just a noob.

**Current status**: After playing a bit I managed to do this either efficiently or transparently, but not both. I would like to do both.

The load balancer process is written in Rust and uses `io_uring`.

**Efficient approach**:

* LB binds to a socket and fires a multishot accept
* On client connection the LB perform some business logic to decide which container should handle the incoming request
* If the service is scaled to zero fires up the first container
* If the service is overloaded fires up more instances
* Pass the socket file denoscriptor to the container via `sendmsg`
* The container receives the FD and fires a multishot receive to handle incoming data

This approach is VERY efficient (no memory copying, very little CPU usage) but the receiving process need to be aware of what's happening to receive and correctly handle the socket FD.

Let's say I want to run an arbitrary node.js container, then this approach won't work.

**Transparent approach**:

* LB binds to a socket and fires a multishot accept
* On client connection the LB perform some business logic to decide which container should handle the incoming request
* If the service is scaled to zero fires up the first container
* If the service is overloaded fires up more instances
* LB connect to the container, fires a multishot receive
* Incoming data get sent to the container via zerocopy send

This approach is less efficient because:

* The incoming container copies the data once (but this happens also in the efficient case)
* We double the number of active connections, for each connection between client and LB we have a connection between LB and service

The advantage of this approach is that the incoming service is not aware of what's happening

**Questions**:

* What can I use to efficiently forward the connection from the LB to the container? Some kind of pipe?
* Is there a way to make the container think there is a new accept event even though the connection was already accepted and without opening a new connection between the LB and the container?
* If the connection is TCP, can I use the fact that both the LB and the container are on the same phyisical node and use some kind of lightweight protocol? For example I could use Unix Domain Sockets but then the target app should be aware of this, breaking transparency
