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.

Ask HN: How do you start over with 2FA and losing your phone?
will generate a PNG file for each account, name after the account name and site name, and containing the QR code for the account.
Going forward, save those PNGs somewhere secure (I use an encrypted tar file). Any new accounts you set up save the QR codes for those as PNGs and add them to your collection. If you keep that collection up to date you will be able to readily handle any device updates or replacements readily or adding new TOTP apps.

Google Authenticator Issues
Scan the code with something else and pass the string inside to a tool like this in order to get the individual tokens/codes: https://github.com/dim13/otpauth

Is there a way to backup everything in my Google Authenticator?
latest google authenticator has an export option. save the url or QR code and you will be able to load it in the next phone (or use a tool such as https://github.com/dim13/otpauth / https://github.com/digitalduke/otpauth-migration-decoder to decode the keys/timers and load in TOTP inside keypassx etc')

Request: support for optauth-migration links

Warning: Please stop using Google Authenticator for your 2FA/TOTP. It has a bad reputation of locking people out of all of their accounts if something happens to the device. There are other better/safer options. Here is my overall advice.
Not tested yet but this tool should allow you to create scanable QR codes for other auth apps as far as I understand. https://github.com/dim13/otpauth

Protoc Plugins with Go
Now let’s take a look at the source code of the protoc-gen-go plugin:

The Tragic Death of Inheritance
Wait, you say, in Go you can embed a struct with default method implementations to "inherit" them in your composed struct... sure, except any methods called by those methods are early-bound in the original struct, completely ignoring your wrapper, so the best you can do is "not implemented" rather than actually implement something. It is at least a way to prevent semver-major breakage, which the gRPC generator uses, but that's about as far as it gets you.

Passing large amounts of data between processes via a file?
The classic answer is protobufs. You can serialize out to binary format.

2022-01-11 gRPC benchmark results
Seems like go is pretty middle of the road. I can only guess as to why but it probably has to do with heavy usage of pointers and reflection which are much slower than other implementations. Gogo/protobuf (RIP) solved this performance with code generation, but the the official go protobuf implementation has essentially eschewed it. I do wonder how the benchmark would look using the new vitess proto library for Go (which has many of the benefits of gogo but with active development and an API built on top of the Google one)

A new ProtoBuf generator for Go
Maybe I'm missing something, but my read of [golang/protobuf#364](https://github.com/golang/protobuf/issues/364) was that the re-organization in protobuf-go v2 was allow for optimizations like gogoprotobuf to be developed without requiring a complete fork. I totally understand that the authors of gogoprotobuf do not have the time to re-architect their library to use these hooks, but best I can figure this generator does not use these hooks either. Instead it defines additional member functions, and wrappers that look for those specialized functions and fallback to the generic ones if not found.
I am thinking about stuff like the [ProtoMethods](https://pkg.go.dev/google.golang.org/[email protected]/reflec...) API.
I wonder why not? Did the authors of the vtprotobuf extension not want to bite off that much work? Is the new API not sufficient to do what they want (thus failing some of the goals expressed in golang/protobuf#364?

How to Auto Generate JavaScript code using GO
In this case try approach with line by line generation. Very much like what protoc-gen-go does for Go code: https://github.com/golang/protobuf/blob/ae97035608a719c7a1c1c41bed0ae0744bdb0c6f/protoc-gen-go/grpc/grpc.go#L142, need to implement this kind of generator yourself.
