Maybe its just me, but I like the fact that adding exponential backoff to an HTTP request goes from http://play.golang.org/p/8WQ8XXrKw0 to http://play.golang.org/p/3tCiNhAfo3 , in no small part due to the explicit error-handling style of

Not sure why the difference in performance between function and non-function, particularly considering this looks inline-able. 2 theories on why gcc is doing better. Maybe its unrolling the loop, and avoids a bunch of jumps. Alternatively,

Again, I'm not disagreeing that exceptions tend to be more terse. Exceptions optimize for writability at the expense of readability. Reading linear code that uses if statements and loops is easier than code that uses try-catches. Especially

Why is it rare for RPC/filesystem failures to not be handled at the level of the call? I think its much more natural for a memcache API to return an error if the server is not reachable, and I can continue to execute the current function. S

From scanning the source, if a websocket connection is backlogged, messages sent to it are dropped. So I'd imagine it'd handle it fine :)

When you're working with streaming JSON like this (or in a web app), it might be easier to use a decoder/encoder. See http://play.golang.org/p/TLNORK2WK9 for an example. Also fwiw, it has never been my experience that json decoding/encodi

Are all of those plugins active all the time? I doubt it. This discussion is getting a little off track. I'm simply saying that dismissing Go for not supporting plugins is rather illogical, as there are a lot of use cases that have no need

Evidence of this memory explosion? Keep in mind that Go processes tend to take significantly less memory than Java processes, especially when dealing with IO related code, i.e. sockets ( http://shootout.alioth.debian.org/u64q/benchmark.php?

Apologies. I misread your post because you were comparing Go to Java and C++, and I erroneously assumed the entire post was talking about those languages.

People who write data structures just give up type-safety when doing so. They don't copy-paste code or write template processors, afaik. A Left-leaning Red-Black Tree, for example: http://gopkgdoc.appspot.com/pkg/github.com/petar/GoLLRB/ll

- It has a more general analogue to enumerations, one that does not add a lot of verbiage to the language spec. ( http://play.golang.org/p/HSh4Ke3pCJ ) - It has an "exception" mechanism that is rarely used, in favour of error-valued return

An answer, by way of analogy. When referring to a friend named "Edward" in a text to another friend planning Edward's surprise birthday party, you can probably refer to him as "Ed" or "Edward". You definitely don't need to refer to him as "

I don't think Russ denied it was a problem, so I don't think this is a "pattern of denial". I think you're incorrectly interpreting that statement as his "fix" for this bug. The fix is well-known (a precise GC), just implementing it hasn't

This is impossible. I don't like to make absolute statements, but I'll stand by this one. In order to pull of an attack, you'd need to know what address range the program in question has been allocated, then figure out the smaller range tha

This is realistically not an issue. First, on a 64 bit machine, the range of actually mapped addresses is small relative to all the possible values that can fit into 64 bits. Second, from an attacker's perspective, the values corresponding

From experience, development in Go can definitely be classified as rapid. The type system stays out of your way, and compile times are insignificant. Try compiling on play.golang.org, or tour.golang.org to see what I mean. About this issue:

It may not be a victory across the board, but it certainly isn't a loss across the board. That's all I'm saying. Let me answer some of your points more specifically: NUMA is a concern, but with some work on the schedular to give goroutines

I was under the impression that even though TLS has the idea of built-in compression, in practice, that is never actually used. Otherwise why would browsers include Accept-Encoding headers, and servers include Content-Encoding headers, wh

Chromium and Chrome Dev Channel has (off by default) pipelining. Pipelining can only be done for idempotent requests, (ie GET only), has head of line blocking problems, and can break proxies. Also, its very difficult to handle errors in a p
