PHP SoapClient: Function ("hoge") is not a valid method for this service. / SoapServer: Procedure "hoge" not present

SoapClient

$client = new SoapClient("http://www.example.com/soap");
$client->hoge("fuga"); // <-exception occurred!
Exception Message
Function ("hoge") is not a valid method for this service.
but...

SoapServer

Of course, WSDL definitions are correct (Function 'hoge' is added).
$server = new SoapServer("http://www.example.com/soap");
$server->handle(); // <-exception occurred!
Exception Message
Procedure "hoge" not present

set soap.wsdl_cache_enabled to 0.

Add below, Both SoapClient and SoapServer.

SoapClient

ini_set("soap.wsdl_cache_enabled", 0);
$client = new SoapClient("http://www.example.com/soap");
$client->hoge("fuga"); // <-exception occurred!

SoapServer

ini_set("soap.wsdl_cache_enabled", 0);
$server = new SoapServer("http://www.example.com/soap");
$server->handle(); // <-exception occurred!

日本でも使えますよ?Chromecastの設定用apkを入手する

Googleのスマホ連携用HDMIスティック「Chromecast」が直輸入、ただし…
ただし、現時点ではChromecast用アプリを国内のGoogle Play/iTunesアカウントから入手することができず、使用するのは難しい状態。どちらのアカウントでも「このアプリは日本では利用できない」という旨のメッセージが表示され、端末にアプリを導入することはできなかった。
そう、正規ルートだとChromecast設定用アプリを入手することは出来ない。けど、
■ Chromecastの設定APKは落ちている
こちらでも紹介されてるし、APKの直リンはここ
■ Chromecastマジで(・∀・)イイ!!

twitpic "Could not authenticate you (header rejected by twitter)."

twitpic
なんか知らないんだけどtwitpicっていうのを使っているサービスがあって、今更、例のtwitter API 1.1対応みたいなお仕事したんですが、twitpicのAPIを叩くと、
Could not authenticate you (header rejected by twitter).
って言われちゃう。
なのでtwitpicのAPIドキュメントのこれ↓
http://dev.twitpic.com/docs/2/upload/
をみたところ、
X-Verify-Credentials-Authorization (Required)
Header Example
1 OAuth realm="http://api.twitter.com/",
2 oauth_consumer_key="GDdmIQH6jhtmLUypg82g",
3 oauth_signature_method="HMAC-SHA1",
4 oauth_token="819797-Jxq8aYUDRmykzVKrgoLhXSq67TEa5ruc4GJC2rWimw",
5 oauth_timestamp="1272325550",
6 oauth_nonce="oElnnMTQIZvqvlfXM56aBLAf5noGD0AQR3Fmi7Q6Y",
7 oauth_version="1.0",
8 oauth_signature="U1obTfE7Rs9J1kafTGwufLJdspo%3D"  

X-Auth-Service-Provider (Required)
https://api.twitter.com/1/account/verify_credentials.json
って書いてあるんだけど、X-Auth-Service-Providerを
https://api.twitter.com/1.1/account/verify_credentials.json
にするのはもちろん、oauth_signatureを作っているURLも
https://api.twitter.com/1.1/statuses/update.json
とかにする必要があったです。はい。
