AI tools make writing code faster. Review, tests and release stay the same size, so the work queues there.

Measure commit-to-production time and rework, not code generated. Fix the narrowest point first.

Separate deploy from release.

"In prod" ≠ "on for customers." Ship on your schedule. Flip the flag on theirs.

If it isn't actionable, it isn't an alert.

One clear signal > a wall of noise. Say what broke and what to do.

Timeouts are features.

Bound every external call. Fail fast. Recover cleanly.

Hanging forever is the real outage.

Canary first, then the fleet.

Roll to a tiny slice. Watch real signals. Widen only when it’s safe.

A contained miss beats a fleet-wide outage every time.

Prefer boring tech when the stakes are high.

Novelty is a tax on on-call. Reliability > shiny demos.

Make the safe path the default.

Least privilege and secure configs should be out-of-the-box — not a checklist under pressure.

A feature without operate/rollback notes is unfinished.

Ship the runbook in the same PR — not a wiki page later.

AI coding agents are fast. Unscoped agents are expensive.

Isolate → least privilege → review before merge.

Guardrails before speed.

@JioCare What kind of response is that? The scheduled visit date was April 14th 2024 and no one has visited the location till now (May 3rd 2024 12:45AM IST) to check whether it's a serviceable location or not. #jioairfiber

[Manu Mathew @manukeerampanal]

Hi @JioCare / @reliancejio
I have booked for a new air fiber connection on 13th April 2024. I haven't got the connection yet. I no longer need it. Kindly refund the money I paid at the time of booking.
Order no. :LR0000073V5S
#JioAirFiber

[Manu Mathew @manukeerampanal]

@JioCare When will you provide the refund? I no longer need the #jioairfiber.
Please give a date in which you will initiate the refund.

[Manu Mathew @manukeerampanal]

@JioCare Today is May 2nd. Still no calls or no refund. What are you trying to say here?

[Manu Mathew @manukeerampanal]

@JioCare I'm really disappointed with the way it's been handled.

[Manu Mathew @manukeerampanal]

@JioCare It's been more than 10 days. I had requested for a fiber connection from a different vendor day before yesterday and I got the connection yesterday. I don't need your connection anymore.
The appointment was scheduled on 14th April. Today is the 25th.

[Manu Mathew @manukeerampanal]

@OnePlus_IN If this is your answer, then, congratulations. You have successfully lost a valuable customer. I'll personally make sure me or none of my family members will ever purchase any other OnePlus devices. If you have any decency, pay back every money I paid for the oneplus care plan.

[Manu Mathew @manukeerampanal]

@OnePlus_IN, @onepluscareIN, @OnePlus_Support, why should we buy devices from you? You are not keeping your word on the services you guaranteed to me. Connecting with you guys since 08/07/2023. Still no proper response. For ref. , look at the following CaseID: 230718-002981
