Pretty cool, I am about to be promoted at my small company to a SWE and our tech stack includes Angular and .Net. Haven't graduated college yet but most of my software classes are in Java, great to know that I am using tech relevant to google.

I use React Native, Typescript, Terraform, Git, GraphQL, Swift, and Kotlin at my job ❤

Every time Neetcode has a complaint about Java, he has to work with another Java project.

As someone who works in software support, a lot of people would be surprised about the amount of Java that is used at Enterprise scale.

The comment on submitting code changes being so easy is so very true. Assuming it's a very simple fix (e.g., typo, comment, trivial bug, etc.), I've had cases where going from noticing the issue, to creating the change, to pushing it for review, to getting it approved, and submitting it, was all done within a few minutes, within one chrome tab (plus the code-reviewer's chrome tab). On the other hand, I've also had cases where relatively simple changes, say about 50 lines of code, could take weeks to forever (aka never) to get submitted, but that's not about tooling, but about scale (when the total power consumption, at data centers, of the function you are changing is measured in how many major american cities it's equivalent to, expect that it will take a while to get that change checked in).

I think there is no problem is you talk about piper or blaze, there are a bunch of talks about them from back 2017 or so. I also believe the same about Boq and Pod, bunch of talks from ServerConf. It would also be nice to explain the languages we use at Google and when. Java and C++ for backend Servers to receive external traffic, JS for frontend, Go for internal services and managed infrastructure(this is mostly my space in GCP), etc…

I was not surprised by GraphQL. It is an excellent open sourced tool. I am somewhat surprised by the lack of Kotlin and Rust usage. I was aware of Java and C++ being used and I understand that large scale apps are near impossible to swap out a language. I just figured there would be a more inclination to use something like Kotlin or Rust for microservices especially considering Oracle's and Google's history. There was also no mention of GCP or even using Apigee with GraphQL so it makes me wonder if they use their own internal tooling for APIs. Other than that, very informative. thanks for the share.

About 5 years ago, it was pretty much the same at Google, lots of internal build tools and custom extensions for various IDEs (emacs, sublime, vi, etc.) that were popular. There was an internal in-browser IDE that could be used, but it wasn't very good, but good enough for light work (quick-fix) or while using a laptop. But with the pandemic, they had to fix that really quick, and get a proper in-browser IDE, which is now a fork of VSCode. Most people I know, including myself, just never switched back after they got used to this new tool, which was pretty much the only thing you could use while working from home (for security reasons, laptops are just portals to cloud tools, so, an IDE has to be either cloud-based and in-browser, or in a terminal on the other end of an SSH connection to a desktop computer physically plugged into the corp network, like emacs / vi / less). I would add that there was a significant amount of friction between the external IDEs or text editors, even with really good custom plug-ins, and the cloud infrastructure behind the version control and distributed build systems at Google, coupled with the famously huge mono-repo. It was often too easy to click the wrong button or hit the wrong shortcut key combo and send your IDE into a tail-spin, trying to chug through the entire mono-repo or the entire distributed build artifacts.
