I got it for one account, not for another one. Must be kind of progressive.

To put it in perspective : there are less than 5 human births per seconds.

So if they want to keep their counter greater than that for a long time, they'll probably have to extend their market beyond humans.

You're right but that's still in a very small subset of possible hashing functions because you must produce a 4 bytes hash, which is then hashed again (to the length of the storage array). Of course you don't have as requirement to avoid collision, just to distribute as equally as possible.

Using chosen hash functions in your applications isn't so rare even outside cryptography field. For example I often use hash for storage addressing (ala git). For this kind of thing you need something fast and with practically no collision (which isn't a requirement for a common hash table).

I think the reasons they don't care more are

1) it mainly affects long time running applications on 32 bits machines. Fact is most production servers are (or should be) on 64 bits

2) most people (me for example) never observed such a phenomenon (and all my dev computers are 32 bits)

So, that's an important problem but far from a game stopper.

For me it's OK. I hadn't see this before and I feel that a discussion without those who don't like Go would be dangerously poor. Thanks for your contribution.

I'm surprised they're on HN but I have a (geeky) friend who do most of his work on an Android tablet so that his "computer" is always on and ready. That makes a difference when you run more than one time in more than on place and you spend a lot of time with your customers too.

It seems to me that if you can buy Fireworks + Illustrator + Photoshop, the difference of price between a Mac and a PC shouldn't be a problem.

Not working on graphics enough to buy those softwares, I'm happy on linux.

Third ?

I'm 40. My grandfather, when he was young, even if he did almost no programming, was a leader in the introduction of computing in press in US and later in France.

I'm 40 and I don't know exactly if I started at 9, 10 or 11.

If you want to play, just play with the toy that looks the most fun. Don't plan for the best route, take the most interesting one. There will be enough occasions in your coding life to be serious and not be given a choice...

And it's self-contained in the sense that when you code you may simply launch it locally :

    godoc -http=:6060

Of course this will be less needed now that the API are stable but that what really useful those last months, when my go weekly was almost never exactly like the one described at golang.org nor tip.golang.org. I'll still use it in planes and trains though.

I see a lot of very good reasons for Google not to lose time rewriting Chrome in Go, even without thinking about webkit, but do you have a reference to support this "200ms" assumption ? I never observed this in my programs (which doesn't have the kind of brutal allocations that a browser must have) so I'm curious.

It really depends on your needs and the type of application you're making. For example my applications, apart serving a few static html, css and js files, just answer to JSON or JSONP queries. That can be done in a dozen lines of code, all the remaining code will be related to your application logic.

So you just need to look at the net/http API, and at a few code samples. I cannot find the the old golang wiki codelab sample (has it gone away with Go1 ?), so here's an example of a JSONP server that you can reduce to a few lines if you remove the specific application logic and the profiling hook : https://github.com/Canop/braldop/blob/master/go/src/braldops...

EDIT : I found an example on the golang site. If you're not interested in JSON, it will be more suited to your need : http://golang.org/doc/effective_go.html#web_server

I don't know if I'll be able to go on with that. When I was coding in smalltalk and at the very beginning of java I was happy to use the full power of my speaking language in my programs but I had to give up my accents because most tools were unable to handle them.

Now that (on linux) most tools deal correctly with UTF-8, I try again, at least on programs that I'm sure I won't share with people not understanding French (for example French MMORPG). Time with tell but I don't take this risk at work.

There should be a lot of complementary answers. Here's one.

Go is a fun language to make concise server programs that will run with no surprise (no exception hiding bugs), that you will compile without looking for something else to do during the waiting, that you'll be able to profile easily, that will include foreign libraries easily, and that will run reasonably fast (and they will feel astoundingly fast because you won't have to wait for them to start).

Or they can label versions like sun, so that nobody will know for sure if they're using Go 2 or Go 1.2 or Go Enterprise Edition or Go Standard...

I made a few web application servers (mostly for games) and it's been a real pleasure, not to mention that my programs run for months handling millions of queries (mostly json) without the slightest problem.

Using the go tool to get libraries, build, compile, test, benchmark, is like a dream.

An example of what I found kind of marvelous : I had sometimes queries leading to the call to a function updating a lot of things in a kind of specific database. That is the browser had to wait about 1 second because there was in the query handling code something like this :

    for _, ami := range amis {
    	bra.EnrichitCouchePNG(ms.répertoireCartesBraldun(ami.IdBraldun, ami.Mdpr), couche, PNG_CACHE_SIZE)
    }

I just made a tiny change and the work was done after the answer was sent to the browser :

    for _, ami := range amis {
    	    go bra.EnrichitCouchePNG(ms.répertoireCartesBraldun(ami.IdBraldun, ami.Mdpr), couche, PNG_CACHE_SIZE)
    }

This small go was the only needed thing (the "database" being yet protected by a mutex)

You're right : there is a lot of redundancy in my last sentence. But we're speaking about a non-nonsensical sentence describing an inept process...

That's a non converging Monte-Carlo optimization with a constant cost function
