Sorry, I had some typos: https://play.golang.org/p/AJskGwEkg-Q The deepEqual fails because I am using realClock in the service implementation while in test I'm using dummyClock. I guess I should just assert that the len of map is 0 and that clk is of type Clock? On Sunday, December 24, 2017 at

A signed nonce is enough to prove private key ownership - as far as it can. Replay attack is unavoidable. Uuid is useful for tracking. But how feasible is this? Here (Hungary, Eastern Europe) we have drugs packed in preprinted boxes, and the serial ids are just pushed into the paper. Per-box per

[go-nuts] methods for error

Inspired by Rob Pike's recent blog post and Dave Cheney's errors package , I wrote down some methods that I think all errors should implement. The key idea is that an error only needs to

Write:broken pipe is usually an indication that an idle connection has been closed by the server. There is an API in database/sql package for this reason. See https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime Assuming you are using MySQL, MariaDB, you can read current timeout settin

I think the verification would have to happen online? But a lot of places are getting online and also, it doesn't have to be perfect. If it stopped 70% of the fraud and the stupid fraudsters, that's still plenty? On Sunday, December 24, 2017 at 2:07:51 PM UTC-5, Damian Gryski wrote: > > In crypt

The UUID (or similar). The aztec code would be unique for each bottle. Also, the manufacturer could provide verification of that bottle provenance in terms of dates, when it was first verified, etc. A fraudster could copy a whole pallet, but it would be a heck of a lot of work and they'd have

In cryptographic terms, this would be a "replay attack", although I'm not sure how any of the standard mitigations would apply in the resl world, especially if the verification is to be done offline. Damian -- You received this message because you are subscribed to the Google Groups "golang-n

Re: [go-nuts] Re: select multiple expressions per case

Many important concerns are unaddressed here. Inside the clause of a "v1 := <-c1" the identifier v1 has meaning -- it is the value by which one refers to the successful receipt. Inside the clause of a "v1, ok1 := <-c1" v1 is either the value received when ok1 is true or the zero value of the type

Yes, I used the term "app" too loosely! I was thinking a progressive website (or whatever the term should be) that can be "app-ized" on smartphones.
