Just Use Go

• nathanasmith 5mo ago
  I start out writing most of my terminal applications and utilities in Python but when something hits a performance ceiling I convert it to Go. That's been a pretty good bar for when it's time to use Go for me and so far so good.

• worldsayshi 5mo ago
  I often think of go as a "better" python. As in, easy to learn and easy to use. But also performant and the module system and package manager seem to be a little neater. (sorry for flamebait) But I wonder how well it can cover similar use cases? Go is great for devops and web backends. But what about AI and data science?
  • chubot 5mo ago
    If Go interfaced with C as well as Python, I’d use it a lot more. But I’m using the slower language because it still integrates with more things For example, one reason AI is all in Python is because CUDA is basically part of the C ecosystem (ie build system)
    • impulser_ 5mo ago
      Have you tried purego? You can just embed the C library into the binary of the Go app call it directly in Go. Most of the time I have found calling C from Go faster or on par with calling C from Python. https://github.com/ebitengine/purego https://github.com/ebitengine/purego

      Go interfaces with C better than Python does...
  • jochem9 5mo ago
    I used to do lots of data engineering in Python, then started doing all kinds of engineering in primarily Go. The Go ecosystem for data is very limited. There are no widely supported dataframe libraries (like the og pandas and the newer polars written in rust and also available as a crate). Very few data science libs, a few decent gen AI libraries, but not as popular as their Python cousins. Most of the work I do now is streaming data and very small batches. For that Go is amazing. I don't need dataframes to transform a json, combine it with a bunch of other data and write to a database. I just need to write that logic and make it go fast. Very easy in Go.

Kotlin might pull me back into the fold though for when I can't use Go.
    • jeberle 5mo ago
      The good stuff landed in Java 8, so you left the party too early. From Java 8 on it has changed direction completely (less OO + JavaBeans, more functional + ADTs). It feels like a completely different language from the Java 1.4 / 5 days. https://en.wikipedia.org/wiki/Java_version_history#Java_SE_8_(LTS) https://en.wikipedia.org/wiki/Java_version_history#Java_SE_8...

  With agentic coding you can just use Rust. AI agents are really good at Rust and the good error message the compiler and or borrow checker gives makes it easy for the AI agent to adjust its code and fix it. For non agentic coding Go has terrible error handling. It does not have exceptions or monadic error handling. Some call that a feature but many avoid Go or that specific reason. This will not change because that debate has been settled so if you can live with if err != nil after each function call (almost) then you are fine. Things that is beautiful with Go are: * Its simplicity * Superb cross compilation support and excellent support for many different OS/arch combos. Not sure if anything comes close to this level of easy way of compiling to Many targets and target support.

    Exactly, I don’t know why we are even arguing over this anymore. People basically don’t write code today so why not use the best languages? Go is handicapped in significant ways which were specifically designed so that it was easier for humans to write. People pushing for Go code in this age either don’t understand the future or the past

    After a few years of Kotlin, I recently ran into what I consider to be some shortcomings here as well, with respect to returning errors. As we know, Kotlin does not have checked exceptions. Ok, but ... The KEEP for Result<T> goes into details, but basically there are a few ways of handling return values + errors: 1) throw exception if something goes wrong 2) return null if something goes wrong (stdlib XXXorNull) 3) Use Result<T> in some cases, its error type is not paramerized and catches CancellationException 4) Use Arrow if Result<T> doesn't meet your needs 5) Return Sealed Classes / Interfaces with all the possibilities. Right now, I am going the Sealed Class interface route, but its such a verbose pain in the ass, so I only use it at certain levels of abstraction (like from a Repository, or library API, etc). The code I needed to write was calling into okio, and it was not straightforward to figure out what kinds of exceptions would be thrown by the JVM layer underneath (docs just say IOException, but sublasses can be thrown). Its sad to see they still haven't figured this out. Rich Errors was mentioned a year ago but its not even in preview yet. Its also not clear how it will work with Java interop.
• 2ndorderthought 5mo ago
  Go is fine for simple applications especially backend ones that connect to the internet. I do prefer it to node/js/ts/etc. I do think a lot of projects would be better served having been written in go instead of java, or whatever else. I don't think it's a panacea for anything. It's pretty easy to shoot yourself in the foot with. The easy stuff is easy the hard stuff is really hard. I like rust a little more, and I don't rewrite things with it. I choose it first. That's my preference but go ahead and gopher on.

  I love Go. But I prefer .NET for web development that also compiles to a binary and has a great ecosystem of libraries and packages. Go is great if standard library works (and it can for many cases) but when you need to start looking into non standard libraries, Go can hit limitations. For example, to build a full production web application with database in Go, there is no great out of the box migration tool. There are some good 3rd party libraries of course but compared to something like EFCore in .NET, they don't come as close. For me, it is now .NET and then Go. Of course, I use Go when just doing a lot of non web stuff as well.
  • bronlund 5mo ago
    Comparing Go and .NET is like comparing a Honda with an aircraft carrier with wheels.
    • MarkSweep 5mo ago
      Eh, at least for people consuming .NET apps compiled with NativeAOT, the experience is similar. Applications can be compiled as a single file with no dependancies. A hello world in .NET is half the size of one in Go: https://github.com/MichalStrehovsky/sizegame https://github.com/MichalStrehovsky/sizegame
  • cloudfudge 5mo ago
    > that also compiles to a binary "compiles to a binary" is not a useful criterion. The criterion Go is winning on is "compiles to a single, completely self-contained binary," meaning it does not depend on libc or any external runtime. You can't say that about .NET. You can't say that about damn near any other programming language. It's extremely rare. The fact that .NET uses a binary packaging format is, like... well ok, so what?

  There's a lot of merit in this. I call Go the Honda Odyssey Minivan of the programming world. It doesn't do anything exceptionally well but it does lots really well and in a way that's simple and reliable. Especially for the backend serving react front end niche. But it's also a pig to write and comes with a lot of foot guns. Especially the Null handling. Somehow they made it worse than every other language.
  • lanstin 5mo ago
    Nilaway linter FTW here.
  • a012 5mo ago
    Why the Null handling and in Go is worse than others?
    • treis 5mo ago
      It sets primitives to 0, "", false etc. Which is almost always but not always fine. And if they're complex objects you still get NPEs To get true nullable fields you need to use pointers. That's a whole topic in itself but they're awkward. It's much worse than true nullable objects that your compiler can check for NPEs. It throws fewer NPEs but at the expense of data integrity where you don't know if your 0 is actually a 0 from the user or a null.
      • Lvl999Noob 5mo ago
        What if Go went all the way? Referencing a zero pointer (nil) gives you the zero value of the pointed to type. If you try to access a zero map, it tries to deference the zero pointer to the underlying buffer. The zero pointer gives you the zero slice with zero length. The presence check fails without crashing and you get some pretension of reasonable behaviour.

    I've typically leaned towards Python for my agentic programming, because the LLMs have been good at it and I'm familiar with it if I need to take a look. But I'm just finishing up an apt-cacher replacement and decided to use golang and the experience has been really great. I'm using CC+Opus 4.7 max effort, and it's produced a working apt cacher from the first phase of development, so far there have only been a few things I've had to ask it to fix. This is over ~52KLOC (counted by "wc -l"), going on day 3 of it working on it. This includes: caching proxy, garbage collection, "http://HTTPS///" kludge (apt-cacher-ng semantics), MITM https proxy, admin website + metrics, deep validation of metadata and rejecting invalid updates, snapshots of upstream state and delayed metadata update until "hot packages" are available after metadata update... 10/10, would go again. FYI: My agent loop is: "Work on next step, have codex review it, compact", and then a couple rounds at the end of a phase to review the code against the spec, and a couple rounds at the beginning of a phase to create the spec.

      I think your blame is misplaced here. LLMs have poisoned the Web, any reasonable person is right to be extremely very of any content they come across on the web in 2026. The LLM models (or rather the AI companies pushing LLMs) did this. The people who are complaining are reacting very predictably. Between the proliferation of AI generated content, and people complaining about (potentially) false accusations, personally the former annoys me way more.

  Maybe some common complaints about Go are finally less of a problem in the current coding agent era - e.g. ecosystem weakness complaints and verbose error handling. Though TypeScript's type system is maybe still more powerful - and therefore might have the edge for agents writing code? (Not to mention there's probably more TypeScript in the training data for LLMs, though perhaps there's _better quality_ Go - I'm not a Go dev though so I couldn't comment further on this.)

  I know this is nitpicky, but whenever I see Go code I see those capitalized function or variable names and know: “aha, these were imported from another file; or will be exported later” and I think to my self: “why? oh why is that relevant information for my at this point in the code?” and I just think about what kind of a weird ill thought out design decision that was, just to save authors from writing an “export” keyword, and further judge the rest of the language predicting it must have more weird design decisions in it.
• thomascgalvin 5mo ago
  I like go, but a lot of little things stop me from loving it. Like, enums. I get a lot out of the box when I use an enum in Java or Kotlin. Converting to/from a String is trivial. Type safety ... exists. I can do that in Go, but I have to hack it in, for every single enum type I want to represent. Enums are not a thing in the language, which means its easier to keep the language in your brain all at once, but at the expense of making it harder to keep the software I'm writing in my head. Is this "enum" the same as that "enum"? I have to go read the code to figure it out. But Go is excellent at a lot of things. Compile times, static binaries, resources compiled right into that binary, execution speed ... there is a lot to love.

• binaryturtle 5mo ago
  Go, similar to Rust, has a horrible ecosystem, IMHO. I want to like it, but they already broke backwards compatibility with older systems (try to get the Go compiler running on a slightly older OS X, f.ex.), and for a compiler that's a no-go to me.
  • jvanderbot 5mo ago
    I regret to inform you, but the post was not about maintaining old systems, it was about simplicity in creating services using a language purpose-designed for creating services. The modern underlying os/docker image was kind of a baked-in assumption.
    • binaryturtle 5mo ago
      The post was about Go and uses the "The boring choice is the right choice." point at the end. But a compiler that's so quick to abandoned previously perfectly fine supported systems, and basically is bleeding edge, is anything but the "boring right choice". I personally prefer long term stability in the toolchains I use for my projects at least.
      • Milpotel 5mo ago
        What language/toolchain/platform are you talking about because C/C++/Python/... all have the same issues?
        • binaryturtle 5mo ago
          Bootstrapping a modern/ up-to-date C/C++ compiler works, getting an up-do-date Python onto the system works too. No such issues with either of those. But try the same with Go or Rust and you hit nasty roadblocks (in both cases the older OS was previously supported just fine.)
          • Milpotel 5mo ago
            I'm not sure what C/C++ compilers you have in mind but bootstrapping older GCC and LLVM versions on modern systems is far from trivial and typically requires patching (e.g. older LLVM versions do not compile with modern compilers) and pinning a whole ecosystem (cmake, C lib, autotools, ...). The same is true for the other way around, modern C compilers usually do not compile on older systems and you get lucky if you find a round trip of several versions that get you a roughly working compiler at some point.

    how is go a weakly typed version of python or php? or even more generic, how is go weakly typed? explain please.
    • zbentley 5mo ago
      I suspect that this is breaking type systems out onto separate axes: strong/weak and static/dynamic. Many consider Python to be strong/dynamic.
      • em-bee 5mo ago
        depending on the definition of static and dynamic, go could arguably be described as static (personally, i prefer declarative, as static is generally defined as something that i understand to be true for C but not for go), but that still does not make it weak.
        • antonvs 5mo ago
          I'm saying Go has a weak type system. This was apparently an intentional choice by the authors. Go doesn't even have sum types, which are an extremely basic, foundational feature of type systems. Even C had an equivalent in its union types. "Weak type system" means that there are many restrictions on what constitutes a valid program that can't be expressed in Go, that can be expressed in languages with stronger type systems, like Rust, Haskell, or even Java and C#.
          • em-bee 5mo ago
            ok, fair enough, what actually interests me is why in your opinion it is weak. in my understanding, weak typing comes from values being interpreted differently or are silently converted based on how they are used. php taking strings with numeric values when used in a math operation is a form of weak typing. if that is not what you mean then you are using a different definition for weak typing. that's ok, i don't want to argue about what is the right definition, but i am interested in the definition you are using.
• BadBadJellyBean 5mo ago
  I can write go but I don't prefer it. It's ... okay. Things I dislike: - if err != nil. Just give me some syntactic sugar instead of letting me write the same thing a bajillion time. - no way to bind a struct to an interface. I'd like my IDE to tell me when I accidentally stopped implementing an interface - some stdlib parts are too bare bones. Unpacking an archive requires me to handle all files, directories, links, etc. myself. There is no move command that can move a file or directory across fs boundaries. The little things.
  • calcifer 5mo ago
    > I'd like my IDE to tell me when I accidentally stopped implementing an interface I don't know about others, but Goland's analyser is pretty powerful and can navigate from interface to implementation(s) and vice versa.
    • BadBadJellyBean 5mo ago
      In my experience only when you implement it correctly. If I add a new method to the interface I can't navigate to the implementations anymore because they don't completely implement the interface.
      • calcifer 5mo ago
        That's surely the correct behaviour?
        • BadBadJellyBean 5mo ago
          It is. But it's also an inconvenience. In a language like Java I can just say that a class implements an interface. If the interface changes the compiler and the IDE tell me about the missing methods. Go not so much.

  • shantnutiwari 5mo ago
    Agreed-- c# has a lot of these advantages and is a lot easier to write (yes, I know this will depend). Plus it has a much larger ecosystem The only thing I can think of: I dont think c# can compile as easy to a single executable binary, like Go (or even rust)?

  • 2ndorderthought 5mo ago
    I can see reasons why people don't want to use .NET if Go is available. .NET has its merits but it's bloated, compilation is slow, and I find it's tooling to be really annoying. For me go is just above c# and both of those are not super high on my list.
    • xnorswap 5mo ago
      I've never understood what is meant by "bloated", would you mind explaining, so perhaps I could better understand? If it's "Large standard library", I think that's a selling point. Having anything you need available ( although these days, via optional microsoft.* packages ) helps keep projects consistent between different places. If it means "Different ways to do the same thing", I can understand that criticism better, and some of that comes with 20+ years of legacy, where the wrong thing was done, and now there's a better way, but a ruthless adherence to backward compatibility means that the old way isn't dropped.

  I got turned off of Go pretty fast by GOPATH shenanigans and polluting my home directory for no reason, since I don't think a programming language should really have any say on my filesystem.

  How well does Go handle GPGPU?
• dadoum 5mo ago
  I would like someone to explain me Go. Really, I will use strong words but that's really what I feel. The syntax changes a lot from the C one, and I can't see any reason for it. To me, it looks unstructured, with the lack of colons for example. It ignores memory safety, it feels like it ignored all of the typing system research since C, no discriminated union, and structures and types in general are heavy to write. It encourages bad patterns, errors out on mundane things like an unused variable, forces you to handle errors with a lot of code while not catching much more than C in terms of bug-prone practices. The package/module system is a nightmare for contributing to open source projects. Modifying a dependency to find a bug is very hard, even swapping a dependency (version) is annoying. And what do you get from all of this compared to C? A garbage collector, tuples, and goroutines. No metaprogramming (aside from generics, and that was a whole story), interop with C is limited. To me, it looks like it does not focus on the algorithms, but on the code implementation, which is imo what leads us into poor programming and missing critical logic flaws, because the logic is buried. I may have forgotten other gripes I got while working with Go, but honestly, if I wanted all of that, I would pick D, at least it interops well with C and has metaprogramming (and has been made earlier, which excuses a little the lack of certain things). But really, I am open to someone explaining me how they enjoy Go. Because I feel like I should be wrong as I see most people (which, for some of them, I know are clever) praise Go. Edit: I added modal expressions to make it clear that it is my opinion.

    I like it because I have more control over the size and layout of my memory structures than many GC languages, and the goroutine/channel data flow design model lets me use all the cores pretty evenly without having to worry about mutexes or subtleties. Pretty easy to get into the 100k request per second performance regime without special tweaking. I tend to either write long lived servers where the performance per container directly affects the cost, or analytics sort of Calais where I want my laptop to use 1/2 or 3/4 of its cores and get a faster answer from scraping 10M whatevers.
  • sliken 5mo ago
    C, for better or worse, is like a high level assembly language. You can do anything, which pretty much means you are going to have many security and correctness issues. Double free, use after free, off by one errors, buffer overflows, etc. Thus numerous CVEs. Go has less flexibility, no pointer arithmetic, a healthy package system, and a smaller domain. Mostly consuming or providing network services. My favorite feature is channels. For me they make levering the performance of multi-core CPUs straight forward, and dramatically nicer than the C approaches I've tried like pthreads and mutexes. I wouldn't rate go as secure as rust, but has a pleasingly developer friendly approach. Seems way more secure than C. Making a pipeline where each stage is 1 to N threads is pleasingly easy, reliable, and performant.

  I should write one of these for Haskell. Huffing abstractions is great for boring, line-of-business applications. Goroutines? Meh. Software transactional memory and green threads? Heck yeah. An actual type system? Chef's kiss. Scott Wlaschin from the F# world has written and talked extensively about F# for "boring" software. It works equally well in Haskell. You don't need to use type-level meta programming to spit out a basic service. Monads are a great honking idea, btw.

  Now that LLMs can breeze through the Rust boilerplate there's no reason to ever write Go again. It's one of the dullest, most mediocre languages out there and despite a nice toolchain and the fact it's undoubtedly a "safe" choice, I just have zero interest.
  • OutOfHere 5mo ago
    Someone has to review the LLM generated code. If it's not the developer, it's the SRE at 2 am. For someone without significant experience, it might be harder to review Rust than Go.
    • barnabee 5mo ago
      Not sure it's harder. Rust type system makes it much harder to shoot yourself in the foot with nils and errors, at least. Biggest issue is probably the number of 3rd party dependencies every non-trivial Rust app ends up needing.
      • wuschel 5mo ago
        I guess other languages that follow a stricter/larger compile time regimen e.g. Haskell, OCaml, Idris, ATS, F* would be suitable as well for this kind of approach. Like Go, OCaml seems to offer low compilation times.
  • pjmlp 5mo ago
    I bet if Rust was more mature back then, the Python to Go rewrite from Docker, and the Java to Go rewrite from Kubernetes would both have been into Rust instead, and that would be it.
• killbot5000 5mo ago
  I love go, but I find it did little to make concurrency management easier to reason about. Race conditions are easy to write. Go routines have all the same concurrency problems of threads. In the parallel HTTP fetcher, the error is discarded. This will likely result in a panic when the response is nil. Also, what if it a server locks up? Or the underlying socket never connects and never times out? I know it’s a toy example, but one must consider all these things in a real system. Go does have good pathways for these concerns, but it’s also easy to do it wrong. I still have to manually reason about access to variables/struct fields from multiple go routines.
  • lanstin 5mo ago
    I find I have to design servers from a data flow view; when my performance demands let me do everything via channels to worker goroutine pools (including sending a response Channel back to the request handler) I don’t have to do any locking at all. I find when I have to add in mutexes it means I haven’t thought enough about the problem (or I am fixing some hot spot from the profiler, rarely).
  • jesseschalken 5mo ago
    Its absolutely laughable that Gophers act like their language solves concurrency when its actually worse than Java because it has data races. Go added nothing and moved backwards. The language that actually solves concurrency is Rust, but they will never acknowledge that.

        Yeah, I suppose I am in the minority here, but I still judge a posts on their merits. LLM witch hunts are tiresome.

          Unlike witches, LLM content exists. And worse, it has proliferated to a point where you are more likely to spot LLM content in the wild then human written content. Witch hunts are bad because they target innocent people and burn them at the stake. When the whole internet has been filled with LLM content, it is not unreasonable, expected even, that you start accusing everything of being an LLM, because, most likely, it is.

  Just fucking use the language appropriate to the task you're trying to accomplish. Just fucking use the language your colleagues can understand and support for the next few years. Just fucking use the language with the framework and tooling you need to get your job done efficiently and effectively, and one at the appropriate level of abstraction for the project. Just fucking use the language which AI agents can read and write well, because we're in the End Times and this stuff matters. Just fucking use the language with great testing and CI/CD support because you'll be spending longer supporting your code than writing it. The skill is choosing well, and a key realisation is that it's never a one-size-fits-all thing. That's why an article like this is less than helpful, gosh darn it.
• Ukv 5mo ago
  > `if err != nil` is the feature, not the bug. It forces you to look at every place something can go wrong and decide what to do about it Haven't really used Go, but can't someone just `result, _ := foo()` and go on using `result`, not checking any errors? The way Rust does it seems closer to forcing you to handle any errors in order to obtain the result (though it is still easy to just `.unwrap()` without properly thinking about it).
  • chuckadams 5mo ago
    We do want to check for errors, we'd just prefer that it not be a repeated 3-line boilerplate pattern that ends up being >50% of all code. Rust does it with one character.
    • Ukv 5mo ago
      I agree that Rust's approach is better. I'm questioning the claim that Go "forces you" to handle errors, since to my understanding with Go someone can just eschew that 3-line boilerplate, silently ignoring the error, and still use the result (which is bad).
      • 4ndrewl 5mo ago
        The point being that's how you've decided to deal with the error, by ignoring it.
        • Ukv 5mo ago
          Silently ignoring errors by leaving out some boilerplate doesn't really seem like an active/forced decision, or a selling point over the languages it disparages ("[...] hellscape doesn't make errors disappear, it just hides them"). Then that the correct path is the one of more resistance seems poor design, in my surface-level opinion.
          • 4ndrewl 5mo ago
            It is a decision though, and one you have to consciously make for each and every occurrence. You can't just hope some catch block will eventually handle it...

    My experience is directly counter. I've worked in half a dozen very large orgs and moving from interpreted languages to Go in each one made the system easier to reason about, more maintainable, and easier to onboard new team members. Go strikes a balance between all the competing priorities that has, in my personal experience, improved the engineering velocity across half a dozen companies comprised of hundreds of developers each. For two organizations, they made very coupled and hard to reason about code bases, but those were vastly easier to reason about than had they been written in, say, python or ruby.
    • za3faran 5mo ago
      Compared to a language like Python or Ruby, yes it's better for larger programs. Compared to the likes C# or Java? Not a chance.

        Most former java devs I have worked with prefer Go after a year or so. Sample size is probably around 40 java devs leading to about 35ish Converts. However, I have only worked with about 5 or so former C# and while they liked Go, they missed C#. Only one preferred Go. C# is on my shortlist to pick up.

  Go is probably my second least favorite language, right behind C++ You need a lot of linters e.g. to make sure errors are being handled, and the lack of algebraic data types make expressing data difficult. I do think it has merits, but I’ll take type safety over simplicity

  I have been using Go since 2014. I have services that just run without issue. Having backwards compatibility with 1.0 just makes it easier to maintain software. The big plus in the modern era is that the simplicity of the language lends to having agents write Go without much fuss. That and the standard library being batteries include lets you direct the agent to use little or no third party dependencies.

  > if err != nil is the feature, not the bug. It forces you to look at every place something can go wrong and decide what to do about it. No it really doesn't. It litters your code with if statements that are all just about the same, except that one that needs to be different, and you go blind looking at them all and can't spot the difference. And these days people probably just type "tab" and their LLM assistant fills out the entire block incorrectly in one keypress copying the pattern from everything else. But LLMs didn't create that problem. Having to type something never meant you had to think about it, or thousands of "sudo shutdown -r now" commands would never have been run on production databases, because typing "sudo" would have magically made someone think about it, rather than just being keyboard memory. And the problem of reviewing the code and spotting the one error handling block that should be different from all the others is always going to be there for human reviewers. Rust converts the common case boilerplate down into one character: ? which lets you focus on any exceptional error handling rather than a wall of if statements that almost all look alike. And the compiler can see that you're ignoring a Result from a function call and force you to explicitly do something about. Plus you can then use a monad without knowing a single thing about monoids, endofuctors or category theory, and impress your friends.
  • potato-peeler 5mo ago
    > No it really doesn't. It litters your code with if statements that are all just about the same Wrong thing to be bothered with. This allows static analysis of every possible path the code can take. Try to do that with throw/catch. There is a reason many industry guidelines like misra, jsf, etc just outright ban hidden paths. They have been literally catastrophic. There is a reason why many modern languages like go, rust, etc, want errors to be explicitly handled. Go documentation specifically reasons why they treat errors-as-values and why is it like that - https://go.dev/doc/faq#exceptions https://go.dev/doc/faq#exceptions > Rust converts the common case boilerplate down into one character: ? which lets you focus on any exceptional error handling rather than a wall of if statements that almost all look alike Again, wrong way to look at errors. Errors are not a problem for a compiler to resolve. Errors are part of your business logic. They need to be explicit and handled. The syntax of one language vs another is not the point of error handling. Errors are not a distraction. It is your job to review each path the code can take. Code may be written once, but code is always reviewed or audited or referenced more than once. No one is impressed if you write some meta magic one-liner. I would rather be more impressed if I can read your code and form a mental image on how many paths your code takes to achieve an outcome in a single sitting, instead of pinging you for a quick call to explain yourself. > you go blind looking at them all and can't spot the difference > And these days people probably just type "tab" and their LLM assistant fills out the entire block incorrectly in one keypress copying the pattern from everything else Now, if someone is 'going blind' looking at error checks, its because their function is doing too much and has too many failure points. Perhaps one may need to focus on honing their software engineering skills on how to structure their code, instead of hitting that 'tab' more so often.

  Yeah, it breaks when the author decides to move from Github into Gitlab to protest against Microsoft. Time to update all code references to Gitlab across the globe, in every single Go project. Or spend the time configuring redirects between URL mappings, across everything that depends on it. Not to mention that except for lacking garbage collection, even Turbo Pascal 7 for MS-DOS was more modern in language features, with faster compile times, on a 20 MHz powered computer.

    > Yeah, it breaks when the author decides to move from Github into Gitlab to protest against Microsoft. The import path is disconnected from where the build system looks for the files. Of course, the default is to use the import path as an URL, right, but nothing forces you to do that. And if you do, *you* lock yourself to the hosting you use. But that can be hardly blamed on Go. Documentation here: https://pkg.go.dev/cmd/go#hdr-Remote_import_paths https://pkg.go.dev/cmd/go#hdr-Remote_import_paths Full example: https://github.com/rsc/swtch/blob/master/app/rsc-io/main.go https://github.com/rsc/swtch/blob/master/app/rsc-io/main.go tl;dr: Serve this at your domain, update the repo-root when changing host platform for your code: <meta name="go-import" content="import-prefix vcs repo-root">.

  Every time I see those kind of posts, it seems reasonable on the surface. But then you remember than a typical web app might want to do something beyond just serving an HTML template. Like, what if you want some styling or javascript along with your HTML? Either write everything by hand like it's 2003 again, or start inventing a complex pipeline from scratch in Go. Countless of people have spent thousands of man-hours on solving this problem, but you use Go, so now you do this yourself from scratch. Or maybe your app needs some relatively complex database access? Writing SQL-spaghetti only gets you so far until you need to do conditional joins and unions and parameterized subqueries etc. God forbid you want migrations too. Go has no answer for this and you either have to hand roll all those things as well, or spend tons of time comparing countless libraries that do some of things you want, but not quite everything, or don't fit into your pipeline for whatever reason. I'd take an opinionated framework with fat dependency stack that has way more features than I'd ever need over trying to reinvent migrations or CSS preprocessing from scratch in Go, thank you very much.

  > No base image CVE alerts every Tuesday. Citation needed. Go's fat binaries and big stdlib cause most enterprise-mandated CVE scanners to light up with zillions of false positives constantly, because too much shit is present in the binary. Logger package technically could speak protobuf over gopher, even though you use it to write text to syslog? Congrats, gopher and protobuf ecosystems are compiled in, with their vulnerabilities! Multiply that by every single golang binary anywhere in your system (seriously, I was getting CVE alerts for un-hardened stdlib cryptography in a 50loc file copying backup tool that could have been a shell script, and audio format conversion buffer underflow CVEs for Traefik, and many many more for months) and it adds up to a pain in the ass. And heaven help you if you do actually have a vuln in third-party software that needs to be patched without an upstream fix (usually because "upstream doesn't make distributions on golang-$LATEST or $TRANSITIVE-$LATEST and they have a roadmap item to do that next millenium"). You can't install an updated transitive and fix it, you have to recompile and somehow distribute the whole thing. Doing that is never as simple as "go build" for big projects: the remaining 20% of build/toolchain needs that Go itself doesn't cover are inevitably fulfilled by the same pile of it-works-on-the-maintainer's-machine rickety Makefile bullshit we always had, but without even the sanity and conventions of autoconf and friends--and yeah, building others' Go projects in anger/in a hurry is enough of a pain in the ass that it makes me miss fucking autoconf. On balance, I like Go. And there's a lot to hate about dynamic linking and package manager hell. But Go's approach is definitely not without its drawbacks in the CVE/security space.
• jesseschalken 5mo ago
  The single executable deployment hasn't been an advantage for a very long time. C# has Native AOT. Java/Kotlin/Scala have GraalVM native-image, plus Kotlin Native and Scala Native. And of course there is Rust, which compared to Go has better performance, lower memory usage, smaller binaries, safe concurrency, safe resource handling, and a real type system with tagged unions. The Go team built good tooling around a mediocre language. Now most other languages have caught up, and Gophers are left writing mind numbing `if err != nil` checks with no benefits left to show for it.
• kakwa_ 5mo ago
  After having way too strong opinions about this, and even if Go is my go to language, I've stopped caring for this kind of statements. In the end, the language doesn't really matter and extremely rarely is the bottleneck. Python, Java, Go, C#, PHP, Node, Ruby or Scala, for backend stuff, all these languages can do the work 99% of the time. They all have well developed ecosystems, and are sufficiently mainstream to easily find developers. In the end, these languages are just variants of the same tool, and I find more interesting to just pick one and build something with it, rather than bickering endlessly about which one is better.
