Probably complaining from someone used to exceptions and/or assertions, where there is perhaps less boilerplate and manual verification that context bubbles to the right place. You can get there either way, but what you're used to weighs heavily. For your example, depending on my experience, knowing that 1!=2 in some code I'm using directly might be more meaningful or actionable than "out of filehandles for accept()"…

Or anyone who's used a language where errors aren't as stringly-typed as Go and where the compiler can enforce error handling. Exceptions have benefits and drawbacks, but any language that can return a Result type will have better error handling than Go in basically every way.

Solved as long as there aren't native dependencies not managed by pip, which there often are.

Wheels solved this problem in 2013. For context, you can install opencv, tensorflow, ROS, matplotlib, and the entire scipy stack in a virtualenv, with no external dependencies, using wheels. This means that you can generate images, train a machine learning algorithm on them, compare the results to conventional CV algorithms, and display them in an ipython notebook all from a venv. There's a huge amount of C++ and eve…

How do these shallow articles get upvoted so much ? they don't have much specific information except very generic "developer productivity". Let me give a specific example where moving to Go really helped our tooling: Go has some great interfaces, specifically their net & ssh client. In order to perform operations against some machines, we have to tunnel through bastions, however we'd also like the tool to work when a…

Actually moving to Go was a very thorough and long process. We did small example projects and tried out many of the libraries we needed. The blogpost is more of a high level summary of why Go is such a great language.

Why does anyone write web apps in Python? PHP? Ruby? Modern Java and Go are so much faster than the alternatives that it's stupid to consider anything else if performance is important. Golang and Java can manage over a half million HTTP responses a second. Node is pretty fast but why bother when Java is many times more mature in features, tooling, and and supports concurrency... And uses less ram and is usually faste…

> All the big companies are using Java and Go almost exclusively for high volume endpoints Please cite “all the big companies.” Also exclusively? No seriously, that is a bold claim. Google isn’t one of them because most of those hotepots are still written in C++. I don’t know how you can claim this. Based on some occaion company blog posts, changing just one or two endpoints out of say 100? What about Rust? I also kn…

Python was my entry into the programming world, and I've been an evangelist ever since... Or I was until I ran into distribution and parallelism. Since then, Nim has been my go-to language of choice. It is all that Python was, plus unbelievable speed, compiling to shippable binaries, and some other cool language features that admittedly, are still beyond my scope of abilities. Still quite lacking in libraries compare…
