Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Companies: We can't find any good candidates!!! Also companies:
Me in the interview: "Generally, no, a variable can only be assigned one numeric value at a time. However, Javascript is famous for unpredictable behaviors in variable comparison statements, for instance [] == ![]. There's actually a whole library built around documenting this type of behavior this for comedic value, and other more serious libraries geared towards solving the problem. So it's possible that some obscure variable assignment scenario would result in that line evaluating as true, but it's not something you'd expect to encounter in the real world. This has gotten a lot better with typescript and es2022, but still something you need to watch for a bit."

“Go is hard to justify unless at massive scale”
I do see that point of view, didn't think of that, there are some aspects of go which are a bit weird if you never touched lower abstraction languages, yet once you learn what they are, you are all set and you can code in anything. go has the least amount of gotchas I have seen in any programming language. compare it with loads of the weird stuff javascript does https://github.com/denysdovhan/wtfjs and go is like heavenly lol

Learning Frontend/React is the new rat race.
Its a very poorly designed language. Its syntax and semantics are often confusing and unpredictable. There is no well defined mental model of how constructs work in this language.

How Modern SQL Databases Are Changing Web Development - #3 Better Developer Experience
I’ve been through multiple incidents where everything worked fine in the testing environment but ended up locking the production database for minutes when deployed. A category of open-source tools called OSC (Online Schema Change) exists to mitigate such pain, like gh-ost used by GitHub and OSC used by Meta. They work by creating a set of "ghost tables" to apply the migrations, copy over old data from the original tables, and catch up with new writes simultaneously. When all old data is migrated, you can trigger a cutover to make the "ghost tables" production. Check the post below for a great introduction and comparison:
-
We migrated to SQL. Our biggest learning? Don't use Prisma
Sounds like it's basically explained in the gh-ost readme https://github.com/github/gh-ost#how
I think it amounts to "use views to decouple access to the table with a fixed interface" and "use triggers for migrating data between tables"

My Green/blue AWS db deployment strategy for avoiding data loss due to table locks
If the performance of the db is a concern during migrations (locking, high cpu consumption for large writes) there are tools that can help and do similiar to what your describing but with the benefit that they are battle tested tools. This one spring to mind https://github.com/github/gh-ost there are other options as well and its worth reading the trade off docs

Changing column from longtext to mediumtext taking over 2 hours
Not sure which version of MySQL you're using, but one approach would be to use a tool like pt-online-schema-change (from Percona) or g-host -- which will create a duplicate table and then swap it in place of the original table. It's a safer approach when operating in production environments. Here's a good comparison of the tools many people use https://planetscale.com/docs/learn/online-schema-change-tools-comparison

Ask HN: Do you use foreign Keys in Relational Databases
No, especially on large tables with billions of records. They make online schema changes impossible. More details: https://github.com/github/gh-ost/issues/331#issuecomment-266...

Migrating a production database without any downtime
Tip #4: Consider slow-running migrations. Some tables can be so large that the traditional migration way is simply not a viable option for them. In such cases, you can consider embedding the data migration code right into your application, or use a special utility like GitHub's online schema migration for MySQL. A slow-running migration can work in production for days or even weeks. It gradually converts the data by small chunks, so you can carefully balance the load on the database while making sure that it doesn't cause slowness or downtime.

Changing Tires at 100mph: A Guide to Zero Downtime Migrations
Actually I never tried but I was scared by the small print of GH not using RDS themselves [1] and Ghost relying on lower-level features that might be not easily available in RDS. Also I had the impression you have to setup a normal non-RDS replica attached to your RDS master?
