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.

Why are websites requesting access to motion sensors on my desktop?
> WebUSB is actually a W3C open standard.
This is misleading at best. Here’s what the actual spec says <https://wicg.github.io/webusb/>:
> This specification was published by the Web Platform Incubator Community Group. It is not a W3C Standard nor is it on the W3C Standards Track.
It’s an experimental spec by Google (observe the affiliation of the three editors: all Google); Mozilla has adopted a negative position on it <https://mozilla.github.io/standards-positions/#webusb>; WebKit has not remarked upon it.

The baseline for web development in 2022
This is such a lame argument. You want it to be true but have no evidence that it actually is true.
A lot of the Chrome team's "standards" have problems with accessibility, workability on mobile, security[0], privacy[1], or just battery life. Some are neat experiments that are or only will be used in the wild by advertisers to track and identify users.
Because the Safari/WebKit team doesn't have to chase users for revenue like Mozilla does they can afford to be more conservative with what Google "standards" they support. Being able to offer a tighter privacy posture or efficiency is part of the iOS/macOS sales pitch.

Porting USB applications to the web. Part 1: libusb
Limiting it to installed apps still has the problem of users blindly agreeing to something that is fundamentally super dangerous. I don’t believe installing PWAs currently exposes any new security surface, so this would be a significant change, and worse still a persistent hazard with probably no indication of what’s going on when it’s in use. I think there’s still potential in the general concept, but it’d take work and is certainly not ready yet in any browser.
Yes, certain classes are restricted from access via WebUSB for security, https://wicg.github.io/webusb/#protected-interface-classes. But as the note says, it’s about balance: that list is necessary for security, but not sufficient.

Ask HN: It's 2023, how do you choose between MySQL and Postgres?
Friends don't let their friends choose Mysql :)
A super long time ago (decades) when I was using Oracle regularly I had to make a decision on which way to go. Although Mysql then had the mindshare I thought that Postgres was more similar to Oracle, more standards compliant, and more of a real enterprise type of DB. The rumor was also that Postgres was heavier than MySQL. Too many horror stories of lost data (MyIsam), bad transactions (MyIsam lacks transaction integrity), and the number of Mysql gotchas being a really long list influenced me.
In time I actually found out that I had underestimated one of the most important attributes of Postgres that was a huge strength over Mysql: the power of community. Because Postgres has a really superb community that can be found on Libera Chat and elsewhere, and they are very willing to help out, I think Postgres has a huge advantage over Mysql. RhodiumToad [Andrew Gierth] https://github.com/RhodiumToad & davidfetter [David Fetter] https://www.linkedin.com/in/davidfetter are incredibly helpful folks.
I don't know that Postgres' licensing made a huge difference or not but my perception is that there are a ton of 3rd party products based on Postgres but customized to specific DB needs because of the more liberalness of the PG license which is MIT/BSD derived https://www.postgresql.org/about/licence/
Some of the PG based 3rd party DBs:
Enterprise DB https://www.enterprisedb.com/ - general purpose PG with some variants
Greenplum https://greenplum.org/ - Data warehousing
Crunchydata https://www.crunchydata.com/products/hardened-postgres - high security Postgres for regulated environments
Citus https://www.citusdata.com - Distributed DB & Columnar
Timescale https://www.timescale.com/
Why Choose PG today?
If you want better ACID: Postgres
If you want more compliant SQL: Postgres
If you want more customizability to a variety of use-cases: Postgres using a variant
If you want the flexibility of using NOSQL at times: Postgres
If you want more product knowledge reusability for other backend products: Postgres

Show HN: Postgres WASM
I was wondering if anyone had thought about using this to experiment with the planner.
The engineering and support teams at Greenplum, a fork of Postgres, have a tool (minirepro[0]) which, given a sql query, can grab a minimal set of DDLs and the associated statistics for the tables involved in the query that can then be loaded into a "local" GPDB instance. Having the DDL and the statistics meant the team was able to debug issues in the optimizer (example [1]), without having access to a full set of data. This approach, if my understanding is correct, could be enabled in the browser with this Postgres WASM capability.

What’s the Database Plus concept and what challenges can it solve?
Today, it is normal for enterprises to leverage diversified databases. In my market of expertise, China, in the Internet industry, MySQL together with data sharding middleware is the go to architecture, with GreenPlum, HBase, Elasticsearch, Clickhouse and other big data ecosystems being auxiliary computing engine for analytical data. At the same time, some legacy systems (such as SQLServer legacy from .NET transformation, or Oracle legacy from outsourcing) can still be found in use. In the financial industry, Oracle or DB2 is still heavily used as the core transaction system. New business is migrating to MySQL or PostgreSQL. In addition to transactional databases, analytical databases are increasingly diversified as well.
