Kind of crazy seeing Go packages which are effectively WASM builds of C libraries running in a Go WASM runtime, like this sqlite3 port. So that’s WASM sandwiched between two layers of Go. A “WASM smash burger,” if you will. Still, if you want to avoid using Cgo, then I can understand the motivation.

Interesting development in the world of Go: in 1.26, the new() function will now accept expressions, not just types. This returns a pointer to the value, which will be useful for those types that use pointers for their fields:
type User struct { Age *int } user := User{} var age int = 10 user.Age = new(age)It also works for literal values, so that temporary
agevariable is strictly not necessary, although the linked post does state that it requires some consideration for types. Havinguser.Age = new(10)will work without issue asnewwill return a*int; but ifAgewere a*uint, you’ll get a type error.I go on about unnecessary pointer types in the past (and will probably continue to do so in the future). To me, it’s just one of those paper-cuts you encounter in your day to day that you know can be made easier. So I consider this a welcome change. It’s not going to same me a ton on code, but every little bit helps.

Dear Go developers,
You don’t need to return pointers,
Unless you do need to return pointers.
But if you think you need to return pointers,
You probably don’t need to return pointers.Instead, consider just returning regular struct values. Keep the nil-pointer panics at bay.

Request for a go linter: something that would warn when an variable with the name
erris not of typeerror:func Bla() { err := 123 // 'err' not of type 'error' }Would’ve saved me a few hours today trying to test if a Future was not-nil, without actually waiting for the result.

There’s no reason to use Testify’s Suite package for Go unit tests anymore. It’s possible to do whatever you need to do with Go’s builtin test runner. Furthermore, most IDEs are smart enough to detect and run sub-tests that use
t.Run(). So save yourself some trouble and just use the defaults.I guess my point is that it’s nice to be able to run specific unit tests directly from the IDE, and that’s difficult to do using the Suite package.

Does Google ever regret naming Go “Go”? Such a common word to use as a proper noun. I know the language devs prefer not to use Golang, but there’s no denying that it’s easier to search for.

Broadtail
Date: 2021 – 2022
Status: Paused
First project I’ll talk about is Broadtail. I think I talked about this one before, or at least I posted screenshot of it. I started work on this in 2021. The pandemic was still raging, and much of my downtime was watching YouTube videos. We were coming up to a federal election, and I was getting frustrated with seeing YouTube ads from political parties that offend me. This was before YouTube Premium so there was no real way to avoid these ads. Or was there?

Why I like developing in Go vs. something like NodeJS: my development setup doesn’t randomly break for some weird reason. When it does break, it’s because of something I did explicitly.

Why I'm Considering Building A Blogging CMS
I’m planning to start a new blog about Go development and one of the things that I’m currently torn on is how to host it. The choice look to be either using a service like blot.im or micro.blog or some other hosting service, using a static site generation tool like Hugo, or building my own CMS for it. I know that one of the things people tell you about blogging is that building your CMS is not worth your time: I myself even described it as “second cardinal sin of programming” on my first post to micro.blog.

Offical support for file embedding coming to Go
I’m excited to see, via Golang Weekly, that the official support for embedding static files in Go is being realised, with the final commit merged to the core a couple of days ago. This, along with the new file-system abstraction, will mean that it will be much easier to embed files in Go applications, and make use of them within the application itself.
One of the features I like about coding is Go is that the build artefacts are statically linked executables that can be distributed without any additional dependencies. This means that if I wanted to share something, all I need to do is to give them a single file that they can just run, without needing to worry about whether particular dependencies or runtimes are installed prior to doing so.

Remarks on Go's Error Handling using Facebook's SDK Crashes As a Framing Device
There are new reports of Facebook’s SDK crashing apps again due to server changes. The post above links to Bugsnag article which explores the underlying cause: that’s worth a read.
I’m going to throw a shout-out to Go’s approach to error handling here. I’m not saying that this shows the superiority of Go over Objective C: these sorts of things can happen in any language. The difference I want to highlight is that Go treats error handling as part of the standard flow of the language, rather than the exceptional flow. This forces you to think about error conditions when you’re making calls to code that can fail.

On Go’s Type Parameters Proposal
The developers of Go have release a new draft proposal for type parameters. The biggest change is the replacing the concept of constraints, which complicated the proposal somewhat, and replaced it with interfaces to express the same thing. You can read the proposal here latest proposal here.
I think they’re starting to reach a great balance between what currently exists in the language, and the features required to make a useful type parameter system. The use of interfaces to constrain the type, that is declare the operators that a type must implement in order to be used as a type parameter for a function or struct, makes total sense. It also makes moving to type parameters in some areas of the standard library trivial. For example, the sort.Sort function prototype:
