Thanks for talking about this talk. Rob is no longer a Go core team member (he's retired now), and explicitly mentions this a few times during the talk, but he sees it as one of his more successful children, and he loves where it's at now. The talk is 100% opinion based content from one of the inventors of the language. It wasn't vetted or approved by anyone from Google, and I don't think he'd conform to anything they would have pushed or suggested for this talk. It's remarkably candid. He also happens to be one of the people who have been around for so long, and invented so much stuff (UTF8 anyone?) that I regard his opinions as worth considering for longer than average. I had the privilege of being one of the MCs at this conference. I introduced this particular talk, and was running madly around the theater with a mic during Q&A. Rob is a lovely guy, and if you ever have the chance to talk to him he's a fountain of knowledge and stories.

On the one letter variable name thing, I work with a fork of nginx and the core modules are nightmarish to follow because of this. I dread debugging the upstream module a seeing a pointer called c and not sure if it is a pointer to the connection, cache node, cache module, config or what else. Then you jump into a function call and you have another pointer call c which is something else, and you better remember that when you go up the stack again that c no longer means what it meant before. It hurts me physically.

FWIW, all those single-letter variables are conventions within the Go community. In Go code, 'c' stands for 'channel', 'w' is 'writer'. If you've read enough code in the standard library, which is like the go-to advise for looking at idiomatic go code for people new to go, and many popular Go libraries, you'll see this convention abound. I don't know what 'nn' is though. I had the same reaction he did when I first encountered them too.

14:48 - Python does exactly this. At least, as of Python 3. There is no integer overflow in Python. The integer just gets bigger. They smoothly scale the representation under the hood. Of course, in Python, nobody is expecting anything to be blazingly fast and so that works. But I think he's right, and I also think that could be made not ridiculously expensive. I'm going to think about making an integer type in C++ that can do this. Though, in C++ the performance degradation involved is going to concern many more people. It can probably still be made pretty efficient, and would be really helpful when dealing with data from untrusted sources.

In C++, they could use the type system to only impose it on some integer, like std::size_t. Generally, as Prime said, you don't want overflow for size computation but it is OK for others integer.

At the lowest level, Elixir and Go concurrency are very similar - both use light weight user space tasks managed by a scheduler per core. Both use preemptive multitasking to achieve high throughput when 1000s or 1000000s of processes are spawned. Differences are in the details: go bakes in preemptive interrupt checks into the compiled binary, Elixir runs on a VM where VM opcode handling does that. Go has a shared global heap, Elixir has a separate heap per process. Go has global GC that sometimes needs to stop the world, Elixir has per process GC that allows everything to keep running always.

The fact that Go launched without generics baked in was a huge misstep. It is a language feature that is kind of de facto required for any statically typed modern language. It's cool that it's finally in the language now, even though its implementation is not pretty.

These days am liking Swift - they’re making an earnest effort to get it to be a multi-platform language (not just for the ghetto of MacOS and iOS), and the subset of the language, embedded Swift looks most interesting - have my Pi Pico in hand to give that a spin. But my main focus will be Swift as for Linux/BSD programming. Swift started out with more things - like generics - thought out up front. The enum of Swift is arguably its best feature - given the manner of programming it gives rise to. And I like that struct and class are very distinct. Anything based on class will always be dynamically allocated on the heap and lifetime tracked using ref counting. It is intended for an object-oriented programming approach. Whereas struct is a value type and a structure instance can be on the call stack. Protocols are analogous somewhat to, say, interface in Java. But the intersection of enum, generics, protocol, struct, class is where all the special sauce comes into play. With version 6, Swift is a language worth giving some attention to.

Go errors are worse than exceptions in everything except performance. Go errors are dynamically typed, thus it is entirely possible to have a dependency introduce a new kind of error, and your code will still compile, but crash or do something bad in runtime. The optional error chaining is laughable as well. To sum it up, the Golang way of error handling has all the problems of exceptions without any of the benefits.

⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠@@DevlogBillDon’t listen to that comment lmfao. Golang’s errors are primitive but still top tier when compared to exceptions. Function definitions allow you to tell when a function can error which you don’t get in exceptions. Values are returned along side errors so you don’t have scope issues like you do with exceptions. With errors being returned directly from a function you have fine grain error handling that let’s you place error handling logic directly next the function that errored which is also not a thing with exceptions. And just because error is an interface, doesn’t make it dynamically typed, it’s still strongly typed. If a dependency introduces a new error type, you still have an error interface. If that dependency has a custom error type you can match it with errors.Is and errors.As, which is completely type safe. Overall that person doesn’t know what they’re talking about and is most likely a JavaScript Bill.

So I am learning more about React and at the moment only learning about how to create a restful api with GO.

1:00 As a dev who's comping from the engineering math side of things who has seen a lot of fortran and c code that looks like it's coming from a physics or analysis math book, I disagree that single letter variables are always a bad thing - especially when each of them are confined to clear local scopes & you happen to have to deal with a lot of them at the same time. if you don't know: using single letter names in math, physics & engineering for local or bounded scoped variables, constants or expression is not just a -decades- centuries old way of writing things, it's also more readable when you get more complicated expression. But granted, the stuff that this go-programmer wrote isn't anywhere near that kind of complexity (nor are most things programmers write).

I had similar pain trying to introduce an option type to my typescript projects, if you're truly committed to not allowing null/undefined sneaking into your code you have to wrap every single thing and have mappers for anything that returns an object to 'optionify' whatever fields inside that can be null or undefined. Better hope they've documented all that. It becomes tedious at best and just absolutely miserable at worst but in a smaller projects it can be manageable.

Go was "against the grain" at the time because we had single core processors, and they weren't the best, and so the whole "threads are bad" thing that lasted a few years was right before dual core cpus dropped, and we started writing code to take advantage of multiple cores. Then IPC got better, memory got faster, and threads weren't such a bad thing anymore. Plus languages like Go helped us realize the power of thread pools underneath, and scheduling chunks of code on those threads to achieve higher concurrency.

Fun fact... fearless concurrency is what got me interested in rust, (and I still regard as one of it's many killer features).

1:45 I agree with Pike and Kernighan: "Use descriptive names for globals, short names for locals" (The practice of programming, 1999). If the entire function is 2-3 lines long, I can tolerate one character parameters, but a full single word is usually better. There's exceptions. E.g. "n" is often used very consistently in some standard functions but IMO most programmers wouldn't get the convention if you just use it as a variable; it's not that hard to use "pLengh" in "WriteString" function (2:14). And "i" is standard: no one should challenge it's use if there's no inner similar loop.

At university, I used a C/C++ language extension for concurrency and parallelism called Cilk+ made/maintained by Intel which was exactly like Go's routines but using the keywords spawn or cilk_spawn instead and with many other features. It came well before Go. Go's approach is not novel and didn't revolutionatise anything. I'm not sure if it spawnned an OS thread or if it had a lightweight thread run-time like go, but that is just an optimization.

13:41 On desktop computing, even back in the early 2000s, arbitrary precision integers should be the default type for what you intuit as “it’s an integer number”. Using fixed-size integer types should be reserved to the following cases: 1. It’s part of an algorithm (e.g. hashing) or standard (e.g. IPv4 or IPv6 addresses are exactly 32 and 128 bit). 2. It’s an optimization you implemented (of course, after profiled profiling revealed its value). For a customer’s age, use a BigInt, unless you profiled and it curbs the app’s performance.

The advantage of BigInt is that all arithmetic integer operations are mathematically valid (within the bounds of the machine), with one exception only that is division by zero. For that, you’d need NaN values in your BigInt type, which depending on your use-case might be fantastic or annoying. Zig is probably right in making overflow on fixed-size integers undefined. In 99% of cases, when something overflows, it’s not the result you wanted anyways. And if overflow is on my mind, in C++, I’ll put a comment right there, which in Zig, I don’t need to because Zig as a dedicated operator screaming that this arithmetic operation is mod 2³² in your face.

Go development tools enforce the single letter shit for functions attached to structs. They also use significant whitespace for efficient compilation or something. Kind of weird, but you get used to it.

Their concurrency model is a "wrong". What GoLang has is way better than your average language in that space but compared to languages that focus on concurrency it was sad to see them recreate something that effectively ignored 20+ years of research in the space (see actor models and Erlang.) While it does move the needle forward in some respects it also holds back the industry because better ways of solving the problem are sidelined. This is why Docker was bad for the industry. It was built by people who were ignorant of the space and built a tool seriously lacking as a result. Its popularity sucked the air out of better alternatives. Less bad != good.

Agree. I don't think the that error handling is "bad", I really like error values, but I do wish that there was some language-level "try" mechanism as you suggested to make it less verbose. Proper enums would also be appreciated.
