the alert is only a signal, the very first step; reducing MTTR and solving the customer problem is the ultimate goal;
an actionable alert is one of the repetitive tasks; Adding a runbook for the repetitive task will help to increase debugging, accuracy, and efficiency in the triaging process.

This post is not intended to explain the video in a comprehensive manner but rather to distill important pieces of knowledge that are relevant to TipTip needs.
Compression is a lossy process to shrink the size of the media, video in this case, to ensure the video can be streamed appropriately according to the user device’s requirements. This process removes information; in a simple example, If two frames are basically identical, we can get rid of the data for one frame and replace it with a reference to the previous frame. Video compression has a lot of techniques; encoding is one of them.
wait, we can do lossless right? yes – but the file high likely is still too large for TipTip use case (and might not make sense anyway).

A while ago, I wrote this https://github.com/rhapsodixx/manager-readme, inspired by the other manager readme. Though it’s debatable whether the doc is useful, to me, writing this kind of doc is intended for ourselves – as managers – to force us to think about what kind of managers we want to be and what is our expectation to work with our directs, explicitly.
3 years afterward, I’m rethinking and came up with this…

Talking about tech management, it’s actually not really about writing code or building a service, it goes beyond. A lot of resources to help you ensure you have decent tech management, but what helps me the most for the past couple of years is: a checklist.
It started with a very simple checklist to expand the checklist that I got from Rutul Davé‘s GitHub.
this is my expanded version from Rutul Dave’s :
who doesn’t love bugs? they are small yet beautiful…ly ruining our life 🙂. Bug is inevitable, choosing 0 Bug as your OKR/KPI is an insane choice, it’s not impossible but it will astronomically hit your productivity & cost, your best bet is to manage it properly. So how are you organizing and managing these bugs? Assigning the right priority(by assessing its severity) is the key, inspired by a couple of references, here is how I typically categorize them.

Running an application without having a proper monitoring is akin to driving without a dashboard. You don’t really know if you still have enough gas, or if you are within the speed limit, or how far are you till your next oil change. There are many uncertainties involved in running an application. Monitoring is instrumental in getting first hand awareness on possible incident or help predict that an incident is about to happen so we can prevent it.
This post outlines some observables that we can monitor and setup alert for along with some recommended practice.
