8月13日（土曜）午後１８時前後からポケモンGO障害発生している模様。
現象は下記の様な感じです。
キャリア回線障害、疑ったのですが、そうでもない。
サーバー、ネットワーク障害かと思っていますが、ネット上でいろいろ調べてそういった情報全くない。。。。よくわからない。
みんなどうですか？
Macに複数バージョンのJAVAを入れている場合の切り替え手順です。
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

GO言語マップに特定のキーがあるかどうかを確認するサンプルコードをメモします。
package main
import "fmt"
func main() {
dict := map[string]int{
"foo": 1,
}
//存在する

fmt.Printf("foo exists. The value is %#v", val)
}
//存在しない
if _, ok := dict["foo"]; ok {
fmt.Printf("foo not exists")
}
golangプログラムで引数で指定された時間でSleepしたくて、いろいろはまってました。
//整数を受け取って、Millisecondの倍数の時間でスリープ、既定は１０００ミリ秒
multipleOfMS := flag.Int("m", 1000, "msの倍数")
flag.Parse()
time.Sleep(multipleOfMS * time.Millisecond)
invalid operation: multipleOfMS * time.Millisecond (mismatched types *int and time.Duration)
multipleOfMS := flag.Int("m", 1000, "msの倍数")
flag.Parse()
time.Sleep(time.Duration(multipleOfMS) * time.Millisecond)
cannot convert multipleOfMS (type *int) to type time.Duration
いろいろ調べてflag.Durationというのがあってこっちを使う
multipleOfMS := flag.Duration("m", 1 * time.Second, "-m=2sのように設定")
flag.Parse()
time.Sleep(*multipleOfMS)
//5秒sleep
go run main.go -m=5s
//500ミリ秒sleep
go run main.go -m=500ms

GOのmacへのインストールとGOPATHの設定をメモします
$ brew install go
インストール先が/usr/local/goとなるはずです。
GOのworkspace（どこでもいい）を作成して、GOのソースコードとパッケージ、実行可能なバイナリファイルを格納します。
一般的に以下のように配置します。
例：…work/
.../gowork/src
.../gowork/pkg
.../gowork/binGO workspaceを決めたので、GOPATHを設定します。workspaceのbinとGoのインストール先binも合わせて追加しておきます。
$ mkdir $HOME/c-ye/gowork
$ vi ~/.bash_profile
export GOPATH=$HOME/c-ye/gowork
PATH=$PATH:$GOPATH/bin:/usr/local/go/bin
これで$HOME/c-ye/goworkの下にプロジェクトごとにソースを配置します。
また、godepをインストールした場合は
$ go get github.com/tools/godep
$HOME/c-ye/goworkのフォルダ中身が以下のようになる。
bin
godep ＃実行可能
pkg
darwin_amd64
github.com/tools/godep/
src
github.com/tools/godep/
diff.go
go.go
main.go
......
testGO/ #自分のプロジェクト

とりあえずこんな感じです。詳しいはこちらを

最近、Play 2.4.4 + Scala 2.11.6でプログラムを書いていて、アプリのデプロイ方法色々調べてたので、binary, jar, war ファイルの方法をご紹介します。
これは推奨されるやり方だそうです。javaさえインストールしていればそのまま実行できます。
構成ファイルbuild.sbtやplugin.sbtファイルに特別な設定入れなくても大丈夫です。
プロジェクトフォルダ(myApp)に入って、activator distを実行する
PS C:\myApp> .\activator dist
これで. C:\myApp\target\universal\myapp-1.0-SNAPSHOT.zip ファイルが生成される。
zipファイルを解凍して、以下のようなフォルダ構造になります。
bin フォルダの下に、2つの実行ファイルがあります。myappはLinux版、myapp.batはWindows版になります。
ファイルを実行する
C:\myApp\target\universal\myapp-1.0-SNAPSHOT\bin> .\myapp
デフォルトポート9000を他のポートに変更することもできます。
C:\myApp\target\universal\myapp-1.0-SNAPSHOT\bin> .\myapp “-Dhttp.port=8080”
※注意：ダブルクオーテーションが必要です。ない場合は、以下の様なエラーが表示される
PS C:\myApp\target\universal\myapp-1.0-SNAPSHOT\bin> .\myapp -Dhttp.port=80
Bad root server path: C:\myApp\target\universal\myapp-1.0-SNAPSHOT\bin\8080
Jarを生成する場合は、sbt-assemblyプラグインが必要です。
build.sbtファイルに以下のコードを追記する。
//configuration for activator assembly : start
import AssemblyKeys._assemblySettings
mainClass in assembly := Some("play.core.server.NettyServer")
fullClasspath in assembly += Attributed.blank(PlayKeys.playPackageAssets.value)
//skip test
test in assembly := {}jarName in assembly := "myApp.1.0-SNAPSHOT.jar"
mergeStrategy in assembly := {
case PathList("javax", "servlet", xs @ _*) => MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".properties" => MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".xml" => MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".types" => MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".class" => MergeStrategy.first
case "application.conf" => MergeStrategy.concat
case "unwanted.txt" => MergeStrategy.discard
case x =>
val oldStrategy = (mergeStrategy in assembly).value
oldStrategy(x)
}//configuration for activator assembly : end
......
project/plugins.sbtに以下を追記する
//configuration for activator assembly
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")
バージョンを0.11.2にしてますが、sbtのバージョンに合わせる必要です。以下をご参照ください。
