I may be mistaken, but I believe type switches in Go address this criticism: type Fruit struct { Name string Species string } // define a method on Fruit structs named Rename func (f *Fruit) Rename(s st

the last time he posted this was in response to me, so I'll join the discussion here to avoid duplication. This was his response when I asked for some clarification: >My problem with Go is that it does not have sum-types and pattern-ma

he's using io.Copy in the main websocket handler, which is a generic, buffered routine for manipulating byte buffers. I don't know if the other implementations are buffered in this manner. It's likely that there are ways to improve the Go

his reporting is very misleading. If you look at the number of messages and connections, Java only held ~5k connections, while Go held just shy of ~10k. In the same amount of time, Java was only able to facilitate the transmission of half

sometimes the truth hurts people's feelings! If they spend 10 or 20 hours making something and it's total shit, don't tell them! If you tell them it's not good, they might fix it! Make sure you tell everyone everything they make is good,

the article fails to mention the food industry, despite the fact that the French Culinary Institute is very publicly developing food printers. You can imagine how Nabisco will feel when you can download the plans to print out Oreos in your

the streaming API publishes the tweets as they come in. Afterwards, if the tweet has been deleted, the streaming API sends out a delete message. That's... the only way to do real time. Otherwise it... wouldn't be real time.

I'm using it on a fairly substantial web back end for a new mobile startup. I've also used it in the past at hackathons. I'm a big fan, overall.

it sounds bad in theory, but in practice it turns out to be quite good. It's actually the opposite; because you know that there's no exceptions, control flow is very obvious. Whether a function does or does not return an error is a part o

>You cannot ignore the error return value in Go. that's not true. You can ignore the second parameter by explicitly naming it with an underscore, like this: x, _ := MightFail()

in fb camera, if you see someone is tagged, and you tap their name, it switches to the main fb app and shows their profile there. The notion of doing one thing well seems to be preserved.

Go has no exceptions. Instead, functions can return multiple values, one of which is an error, and you check the error value on invocation. It's tedious and awful and makes your code very ugly and it's absolutely correct and I love it. I

that's not a Django problem; it's a Python problem. Using exceptions for control flow is idiomatic in Python. Case in point: a generator is supposed to raise a StopIteration exception in order to signal termination.

it doesn't "compile from a url", the package name is just the url address. You still have a directory of downloaded packages analogous to Python's site-packages, and they don't update unless you explicitly update them. The difference is t

No, the model is completely different. In Node, you pass in a callback to establish what should be done following the return of a longrunning I/O operation. In Go, you use goroutines to manage the concurrency. Basically if you say this:

If your json doesn't represent something that already follows some known structure, you have an opaque data structure that you have to hand write a parser for in any language.

if the repository owners tags a commit with the tag Go1, it is used by Go. If there is no tag to specify which commit, the tip of master is used. In practice, most maintainers just keep master clean and do all development in a dev branch.

it looks more like an acid bath for dissolving the support material. It printed out with a white support structure, and in the end they list the volume of support material used for the structure.

The Go program allocates a new item on every line instead of allocating a single struct and just passing a pointer into unmarshal, which would be way faster. There's some claim of "doing async style programming" but the Go code doesn't par

to be honest, I've used both gevent and Go and concurrency is far more natural in Go. Sure, you can do most of what you want with gevent, and if you're using stackless or pypy you can even have channels, but implementing concurrency at the

unlike other languages, a framework isn't as much of a requirement in Go since the Go standard library includes an http server, json serialization/deserialization, html templating, email, logging, basically everything you need in a web app.
