Thanks very much for the feedback, Axel. I didn't think it was harsh, this is just the kind of information I needed before burning needless effort on the idea. Getting started with these conversations is quite intimidating because there is so much information and history, it's hard to find what

Hi All ! There is a package named ast, inside there are a lot of structures like: ast.Comment, ast.Field, ast.Node and so on. And I whould like to use types of those structure as a keys. So, I could not figure out what type of the key I should use in order to store in a map something under the

Honestly I'd probably use grpc and keep a constant connection from the IOT to the cloud. No ports/services required on the client at all and the server can still request things in real time. Like:

Thanks, Matthew. I know what RPC is, but have never considered it as a way to serve http from behind a NAT. I should say that the IOT's are part of a product that's been in the market for several years. My client likes the web interface we built and wants users to be able to access an IOT's

Ian, thank you. but may be the is any workaround ? Use as a key not directly but like a derived from those interface/structure types ? Of course I may declare key like string and use switch + .(type) to mimic it. So, a little bit more. there is a go standard package named ast. the docs about it

[Aside: please don't paste images or coloured text. They're very hard to read] It's perfectly normal for your code to be interrupted once every 10ms or so for async preemption. You'll see a load of system calls, but it should not be making your code run "slowly". If you find that "most of the

Hi Kurtis, good to know that a map will always be "kind of" passed by reference to functions. I have verified that with a short test-program on the playground -> https://go.dev/play/p/HxdgpM-QozM So in the next code-review all those *[maptype] references will be removed. Things are very

Which is also the reason why you can't insert into a nil map - you have to make() one. On Wednesday, 15 March 2023 at 10:58:09 UTC Dan Kortschak wrote: > On Tue, 2023-03-14 at 19:56 -0700, Kurtis Rader wrote: > > Maps are a special-case. You can't pass them "by value" in the sense > > you mean
