Why not "Ivory Coast Bus Routes Redrawn using Cell-Phone Data" ? As someone living in an African country I find this headline beyond ridiculous. If this was in Lebanon would we be reading "Asian Bus Routes Redrawn using Cell-Phone Data"?

I consider myself very fortunate to be coding in Scala. I know of many Java developers who code Java at work and wish that they could land a Scala job.

Wow. Wish I could deploy this sort of tooling behind a firewall.

Mostly because the Java syntax has remained (mostly) unchanged since September 2004. Java 8 will change that, but it's still a far cry from what's available in Scala.

I think the part you are missing and what Whatsapp's engineers are referring to is Google storing all your private conversations and data mining them for information to target you with ads. Whatsapp does not store your messages.

by trailfox 14y ago
Good point. It turns out that the quad core benchmarks on 32bit which I linked to are already using Go 1.1beta, so any speed gains for Go 1.1 are already factored in: http://benchmarksgame.alioth.debian.org/u32q/benchmark.php?t... The 64

I've seen posts where "it's from Google" is cited as sufficient explanation for taking an interest in the language. If Go was a random project on GitHub there is very little chance that I would have given it a second look, let alone learnin

by trailfox 14y ago
Those serious about Go are running (production?) systems using pre-release builds? Is that a common practice?

The quad core results indicate the exact opposite in terms of performance with the JVM clearly ahead: http://benchmarksgame.alioth.debian.org/u32q/benchmark.php?t... Go uses less memory than Java 7, but then again so does Java 1.1

I agree that his comment need to provide more data. I also find that HN in general is very quick to downvote comments critical of Go, even well reasoned ones with sources. In terms of performance data check out quad core results for Go 1 (g

For most applications the startup time is irrelevant. The startup time of a server app which runs for months is not an interesting data point. The throughput in requests per second is far more important and this is where the JVM has been ve

Thanks for the explanation. In most cases cleanup is handled in finally blocks and the unit of work fails if any of N calls fails, in most case it makes no difference which one failed. Where the difference does matter it's probably in a dif

It seems silly to have to check the error return code with an if for every method I call. Surely a try { } catch around a block makes more sense than littering my code with if (errorHappened) in every second line.

So if I'm reading from a file I should use panic recover and not return code checking?? That's not what I've seen in the docs.

I'm interested to see if it is still going to be clobbered by Java and Scala the way Go 1 was.

Lack of exception handling is the biggest reason I haven't used Go for much. The other reasons are that it's just so plain/boring (yes, I know that's subjective), nothing about the syntax is interesting. Learning go is like eating cardboard

Netty has become the standard library for NIO on the JVM and is used widely by programmers in various JVM languages. It's also refreshing to see high performance NIO systems written without using Netty for a change.
