The logical outcome of an escalation like this is that there is no single threaded leader for this user experience, the org charts are wrong, and one or more sr. leaders are culpable. But no one wants to hear that.

This is unfortunately par for the course at many big companies. I have re-lived this exact same thread so many times I've lost count 1. Leader escalates issue to his team 2. The team scrambles to come up with a solution 3. No one wants

Yeah, it's included as one of the gradle scripts which fails the build in CI if the rules don't pass. No template, as it's specific to my team's project, but one example is that we enforce that classes within our core do

I love Detekt! It's particularly good for enforcing project conventions that can't be covered with standard linters. With access to the full AST, you can basically enforce any kind of rule you want with custom analyzers. And LLMs

Almost my entire org uses it for backend server development at Amazon. There is very strong support for Kotlin support within the Amazon dev community.

Someone who actually knows what they're talking about. Even with the Customer Obsession LP, it's not too hard of a stretch to arrive at a conclusion where more ads are shown. Better are worse are, in many aspects, quite subjective

In my Amazon team, we use PostgreSQL as a queue using skip-locked to implement transactional outbox pattern for our database inserts. People commenting 'just use a queue' are totally missing the need for transactional consistency.

Nothing about the outbox pattern guarantees ordering.

Even if are "down to several nano-seconds", a slight clock drift can be the different between corrupt data or not, and when running at scale, it's only a matter of time before you start running into race conditions. For a sma

This is precisely why large tech companies generally offer parallel career progression paths for individual contributors who don't wish to go into management. A Senior or Principal engineer at Amazon carries nearly as much weight, some

A couple ways. If the need is not real-time and analytical, you feed the data from multiple services into a separate BI database which can do slower and more complex joins across data from multiple data sources. Or if the need is real-time,

What does it mean for a field to be required in new API version but optional in the old version?

Man, I remember running this and ophcrack as a 15 year old to recover the windows login password for my mom's computer after she forgot it. She was convinced her password had just stopped working, until I recovered it and she realized

Yup, I work at Amazon and my team along with many surrounding teams are only coding in Kotlin from this point on. The JVM and its ecosystem brings insane value to the table, and Kotlin lets you take all the benefits while removing most of t

Commit messages don’t matter. In fact they matter so little that I'm going to write a blog post about how much they don't matter. Commit messages are probably one of the worst places for documentation and a common source of bikesh

I agree with the author, but it's also possible to take the other extreme where engineers think they don't need any input from product.

First question is already awful. "Haven't eaten in 4 hours? You need to eat!" Give me a break, I skip breakfast and usually do intermittent fasting every day, not eating until 4 or 5 with a high-cal home cooked meal. I feel g

Yup, this exactly. It is often under-appreciated how much an active corporate engagement model is due to 1 or 2 highly motivated employees. Once they leave, engagement drops because it wasn't something being driven from management or P

To elaborate on this, the feature sets on these low level microcontrollers are no standardized. There is no common API for them to implement. Even chips coming from the same manufacturer will have different hardware capabilities, and althou

This is cool and interesting, but for me it's in the same category as photography eccentrics who can develop amazing photos with a darkroom in 2021. I'll stick with my web interface. When that doesn't suffice, I'll check
