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.

Linter to check for errors ignored with _
In our codebase I noticed a few cases where people ignored errors returned from functions by assigning them to _, ie result, _ := foo(). The errcheck linter doesn't seem to catch this, does anyone know of a linter that does?

Golang panics in libraries
And we also expect that the caller will check the error and handle it. There is a popular linter that checks it for us: errcheck.

Is it a bad convention to overwrite err variable?
You should be using golangci-lint, because all serious Go programmers should. golangci-lint contains errcheck, which will detect if you overwrite an error without having done something with it in the meantime. I consider this one of the most important linters (this doesn't just detect things that may sorta kinda someday turn into bugs, this quite likely is a bug RIGHT NOW), and it helps you have the confidence you can overwrite errors as you go and don't need to keep allocating new ones.

Integration Tests failing
Run golangci-lint over your code if you haven't already and pay special attention to errcheck's output.

We'll agree to disagree about unused imports; imports have can side-effects.

Lies we tell ourselves to keep using Golang
I prefer functions returning errors over throwing exceptions. Whether it's Go's errors or ML-style options/results, they're both better than exceptions. I cannot remember the last time I had a bug from not checking an error in Go. There's also errcheck which I use as part of my linting that will catch unchecked errors, such that I cannot even commit the code.

I Want Off Mr. Golang's Wild Ride
> Go compiler raise an error if a variable (error) goes unused
It doesn't though. It's perfectly valid to not use the return value of a function that only returns an error, for instance.
There are static error checking tools you can use like https://github.com/kisielk/errcheck to work around this, but most people don't use them.
I've run into a lack of Go error checking many times. Many times it's just the trivial case, where the compiler doesn't warn about not checking the result of an error-returning function.
But often it'll be subtler, and the result of Go's API design. One example is its file writing API, which requires you to close the file and check its error to be correct. Many times people will just `defer file.Close()`, but that isn't good enough - you're ignoring the error there.
Worse still is e.g: writing to a file through a bufio.Writer. To be correct, you need to remember to flush the writer, check that error, then close the file and check that error. There's no type-level support to make sure you do that.

Trying Out Generics in Go
I'd be really happy with that! Building the functionality of errcheck[1] and ineffassign[2] into the compiler — or at the very least, into govet — would go a long way to allay my worries with Go.
I think the reason they don't do this is that it's a slight (albeit a very tiny one) against Go's philosophy of errors being values, just like any other. While the `error` type is standard and used throughout Go source code, it still just has a simple three-line definition[3] and is not treated as a special case anywhere else; there is nothing stopping you from returning your own error type if you wish. A third-party linter could simply check for the `error` type specifically, but the first-party tools should not, and there's nothing like Rust's `#[must_use]` attribute that could be used instead. I respect Go's philosophy, but I feel like pragmatism must win in this case.

PuTTY vulnerability vuln-p521-bias
The values [0, 15] represent 16 possible values, which is a power of 2.
The correct way to get an unbiased distribution from a sample of 2^x to a modulo that is not an even power of 2 is to use rejection sampling.
This is what RFC 6979 says to do https://datatracker.ietf.org/doc/html/rfc6979#section-3.2
But you can also see this technique in CSPRNG code; i.e. https://github.com/php/php-src/blob/d40726670fd2915dcd807673...

Learning Rust: A clean start
A little about me; I'm a web developer and have been for around 5 years, though I'd dabbled for years. I have experience with Perl and PHP but my day to day is JavaScript/TypeScript be it through NodeJS or ReactJS. I want to learn Rust for no specific reason other than it's fun to learn new things.

WebSocket vs. HTTP communication protocols
Consider a web application where requests are handled through NGINX as the web server and PHP as the dynamic backend language. Let’s say something in the application logic results in a fatal error or process termination. This doesn’t affect NGINX’s ability to serve a response to the client, which would most likely be an HTTP 503 - Service Unavailable message.

Where do React Server Components fit in the history of web development?
In the beginning, I used a technology called CGI to develop server applications written in Perl. This technology was later replaced by Microsoft’s ASP (Active Server Pages) and then PHP. PHP, which you may already know, is still powering over 77% of all the websites as of the time of writing (ever heard of WordPress?).

Shopware Changes since the 6.0 Dev Training Videos
As Shopware is mostly based on the Symfony framework, which is in turn based on the PHP language, we should also consider learning about the basics, which will also be useful for other frameworks apart from Shopware, like Symfonycasts, symfony.com, php.net.
