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.

Show HN: A lightweight PHP library for checking password strength
Lightweight is an understatement here.
A client's project (with not necessarily technical customers) has had pretty reasonable success using the Dropbox originated library[1] for this, `zxcvbn`[2], on both frontend via js (for "instant" feedback) and on the backend via php (to enforce the requirements when writing password hashes to the database)

How long can a password be with the new login system?
Password strength is evaluated based on the zxcvbn library.

How hard could it be? Sorting words alphabetically in Rust
In contrast, let's consider the password "zxcvbn214". How might we assign an entropy to this password? Is it 369? Or 266 * 103? Anyone familiar with a QWERTY keyboard or Dropbox's password strength estimator knows that "zxcvbn" is hardly a random sequence of letters. This same principle applies to "l33t" speak, e.g. replacing all "e"s with 3s and "a"s with 4s. These strategies may "trick" simple entropy calculations into estimating a high entropy, but it won't trick sophisticated attackers. This leads to strength over-estimation, which is, I argue, the worst thing we can do in this context.

You mean the Low-Budget Password Strength Estimator?

Yeah, that name is totally legit.

Which tool can crack this password so fast?
For any part of the password that the zxcvbn cannot match to a known pattern, it uses a brute-force cardinality of 10, i.e., it estimates that the number of guesses required to crack a password or password segment of length N is equal to 10N (equivalent to the number of guesses required to exhaust all possibilities if your password consisted only of numbers).

Bitwarden Design Flaw
We took a similar approach to passphrase stretching in EnvKey[1] v1 (EnvKey is a secrets manager, not a passwords manager, but uses end-to-end encryption in a similar way). We used PBKDF2 with iterations set a bit higher than the currently recommended levels, as well as Dropbox's zxcvbn lib to try to identify and block weak passphrases.
Ultimately, I think it's just not good enough. Even if you're updating iteration counts automatically (which is clearly not a safe assumption, and to be fair not something we did in EnvKey v1 either), and even with safeguards against weak passphrases, using human-generated passphrases as a single line of defense is just fundamentally weak.
That's why in EnvKey v2, we switched to primarily using high entropy device-based keys--a lot like SSH private keys, except that on Mac and Windows the keys get stored in the OS keychain rather than in the file system. Also like SSH, a passphrases can optionally be added on top.
The downside (or upside, depending how you look at it) is that new devices must be specifically granted access. You can't just log in and decrypt on a new device with only your passphrase. But the security is much stronger, and you also avoid all this song and dance around key stretching iterations.

Mastering Code Quality: Setting Up ESLint with Standard JS in TypeScript Projects
JavaScript Standard Style is less opinionated about JSX formatting and largely leaves JSX as-is. In a React project, you should integrate with React-specific linting rules for ESLint. The generally accepted configurations are eslint-plugin-react and eslint-plugin-react-hooks, enforcing some best practices of writing React code.

Building an Email Assistant Application with Burr
You can use any frontend framework you want — react-based tooling, however, has a natural advantage as it models everything as a function of state, which can map 1:1 with the concept in Burr. In the demo app we use react, react-query, and tailwind, but we’ll be skipping over this largely (it is not central to the purpose of the post).
