This is called [type conversion][1] :

    i := 23
    var i64 int64
    i64 = int64(i)
 


  [1]: http://golang.org/doc/effective_go.html#conversions

This is probably obvious, but simplest:

    i64 := int64(23)



    i := 23
    i64 := int64(i)
    fmt.Printf(&quot;%T %T&quot;, i, i64) // to print the data types of i and i64



Using SQL Server 2000, how can I get the first and last date of the current year?

Expected Output:

Is there any way to make a synchronous call with AngularJS?

The AngularJS documentation is not very explicit or extensive for figuring out some basic stuff.

ON A SERVICE:

    myService.getByID = function (id) {
        var retval = null;

        $http({
            url: &quot;/CO/api/products/&quot; + id,
            method: &quot;GET&quot;
        }).success(function (data, status, headers, config) {

            retval = data.Data;

        });

        return retval;
    }

How to change int into int64?

<p>Im trying to convert an integer into an integer64 in go but im having no luck. Anyone know an easy way to do this?</p>


I have tried:

    const ascii = &quot;abcdefghijklmnopqrstuvwxyz&quot;
    const letter_goodness []float32  = { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }
    const letter_goodness  = { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }
    const letter_goodness = []float32 { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }

The first declaration and initialization works fine, but the second, third and fourth don&#39;t work.

How can I declare and initialize a const array of floats?


Declare a constant array

It would be convenient to be able to say something like:


    for _, element := reverse range mySlice {
            ...
    }


Is there a way to iterate over a slice in reverse in Go?

From http://golang.org/src/pkg/database/sql/driver/types.go:

    type ValueConverter interface {
    	// ConvertValue converts a value to a driver Value.
    	ConvertValue(v interface{}) (Value, error)
    }

    var Bool boolType
    
    type boolType struct{}
    
    var _ ValueConverter = boolType{} // line 58
    
    func (boolType) String() string { return &quot;Bool&quot; }
    
    func (boolType) ConvertValue(src interface{}) (Value, error) {....}


I known that ValueConverter is an interface name. Line 58 seems to declare that boolType implement interface ValueConverter, but is that necessary? I deleted line 58 and the code works well.

What does an underscore and interface name after keyword var mean?

Even though I have `GOPATH` properly set, I still can&#39;t get &quot;go build&quot; or &quot;go run&quot; to find my own packages. What am I doing wrong?

    $ echo $GOROOT
    /usr/local/go

    $ echo $GOPATH
    /home/mitchell/go

    $ cat ~/main.go
    package main
    import &quot;foobar&quot;
    func main() { }

    $ cat /home/mitchell/go/src/foobar.go
    package foobar

    $ go build main.go
    main.go:3:8: import &quot;foobar&quot;: cannot find package

Go build: &quot;Cannot find package&quot; (even though GOPATH is set)

Just curious to findout: why aren&#39;t there standard functions like startswith, endswith, etc as part of the standard libraries in the Go programming language?
