海外就職 – オーストラリアでIT(Web)関係の就職活動その1 – 転職の流れ in 2013

Feb 28, 2013

AD:

今月から、本格的に転職活動をしているのですが、いろいろ学んだので、もし日本人でオーストラリアで就職活動をしている方の参考になればと思いまとめました。

ちなみに、今回でオーストラリアでは２度目の転職活動になります。

オーストラリアの就職活動について

会社の規模や文化によりますが、日本とすこし違って、大抵の会社がエージェント（日本でいうところのリクルート）を使ってスタッフを採用します。
流れ的には、こんな感じだと理解しています。

会社はエージェントに、希望のスタッフと条件を伝えます。
そのエージェントが、Seekなどの求人サイトに広告を出します。（こちらの有名どころの求人サイトは９割がエージェントだと思っております）
求人サイトなどから応募すると、エージェントから電話で連絡が入ります。（電話では職歴や、なぜ転職するのか、Visaは持っているのか、技術はどれくらい年数使用しているのかを聞いてきます。）
それでエージェントに気に入ってもらえると、今度はエージェントの会社に行ってエージェントが面接をします。（ここでも、質問は内容は電話とあまり変わりませんが、もう少し質問内容が細かくなります。）
大抵、エージェントまで面接にいくと、具体的な仕事のオファーの話をされます。（今、こんな案件があるけど、どう興味ある？的な感じです。これが実際に求人サイトから応募したものでないときは多々あります、つまり求人サイトの告知は転職、求職者を見つける餌のような役割を兼ねていることがあります）
その後、会社によりますが、技術テストがあります。（独自フレームワークを作ってとか）
その技術テストをエージェントに渡して、エージェントのクライアント（スタッフを探している会社）が気に入ればいよいよ面接です。
面接は会社によりますが、最低でも２回はあります。はじめは電話だけだったりします。
面接では、技術的な質問が多く、今までの経験なども聞かれます。最後には給料はどれくらい欲しいのか聞かれますので、低すぎ高過ぎない程度で答えます。
１回目のテストでは、面接の後にまた技術テストがあったりします。（１時間で、指定されたフレームワークを使ってギャラリーを作るなど）
２回目の面接では、大抵マネジャークラスの人と面接します、ここでも技術的な質問や、過去に何をやったなどの質問がされます。
上記をクリアーすると、ほぼ決まりですが、次はリファリー（推薦してくれる人？）が必要になってきます。
大抵、過去の働いた会社の上司や、現在働いている会社の同僚などにお願いします。転職先の会社が、リファリーに直接電話するか、文章を提出して、本当にこの人が問題ないか最終確認します。
ここまでのステップを全部終了すると、もうあとは社員の契約をまとめて、転職活動は終了です。

次のblogで実際の準備や、やり方などについてまとめたいと思います。

ZendFramework 1.12.* と Doctrine 2.3.*の連携

Feb 24, 2013

AD:

仕事でZendFramework1.*を使用することになったので、ORMにDoctrine2.3.*を使用してみました。
下記の記事は、ある程度ZendFrameworkを触ったことがある方が対象になると思います。

構築環境

composerを使ってやりたかったのですが、うまくいかなかったので、結局手動で、Fileをダウンロードして設定しました。

Ubuntu 12.04
PHP 5.3.10
memcache 2.2.7
ZendFramework 1.12.1
Doctrine 2.3.0

設定に入る前に

KDF Memoさんの記事を参考に導入しました。
おそらく、KDF Memoさんものより、Versionが上がっているので、File構成がだいぶ変わってきているので、地味に設定に時間がかかりました。

最終的に僕のFile構成はこうなりました。

設定

まず、必要なものをダウンロード
Doctrine ORMよりLatestをダウンロードして、./library/vendor/に入れる
zendframework1-doctrine2より、Bisnaをダウンロードして、./libraryに入れるbinフォルダをコピーして、./に移動

cacheの設定などは、KDF Memoさんの記事に詳しく書いてありますのでそちらを参照してください。

MongoDBコマンド＆検索クエリ

Feb 23, 2013

AD:

最近、仕事でMongoDBを使う機会があったので、MongoDBコマンド＆検索関係をまとめたいと思います。

検索クエリ

現時点で僕の理解しきれている範囲だとクエリの特徴は下記のような特徴があるようです。
– メソッドの引数にJSON形式のデータを渡す
– 変数が使える
– 制御構造が使える
– カーソルが使える

条件演算子

MongoDBは、JavascriptのエンジンであるSpiderMonkeyを拡張した、Javascriptシェル？です。
なので、JavaScriptの記述でデータのが取得が可能です。

$gt
greater than (i.e. &gt;)
$gte
greater than or equal (i.e. =&gt;)
$in

MongoDBの状況確認

Feb 23, 2013

AD:

ブラウザから確認

MongoDBをインストールした場合は、下記のURLにアクセスすると、MongoDBの状況が確認できるようです。
http://localhost:28017

ちなみに、上記の機能は–norestオプションで無効化できるらしいです。

コマンドから確認

ちなみに、コマンドでMongoの状況確認は下記の要します。

$ mongostat

Ubuntu12.04にMongoDBをインストール

Feb 23, 2013

AD:

このページを参考にUbuntuにMongoDBを入れようと思ったらうまくいかなかったのでメモしておきます。
やっていることは、GnuPGへキーを登録して、MongoDB用のパッケージ管理システムを登録して、インストールの流れです。

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
$ sudo sh -c 'echo "deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen" | tee -a /etc/apt/sources.list.d/10gen.list'
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen
$ sudo apt-get -y update
$ sudo apt-get -y install mongodb-10gen

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

$ sudo sh -c 'echo "deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen" | tee -a /etc/apt/sources.list.d/10gen.list'

deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

$ sudo apt-get -y update

$ sudo apt-get -y install mongodb-10gen

操作関係

$ sudo service mongodb start
mongodb start/running, process 19200

$ sudo service mongodb stop
mongodb stop/waiting

$ sudo service mongodb restart
mongodb stop/waiting
mongodb start/running, process 19224

$ sudo service mongodb start

mongodb start/running, process 19200

$ sudo service mongodb stop

mongodb stop/waiting

$ sudo service mongodb restart

mongodb stop/waiting

mongodb start/running, process 19224

データの登録、検索

MongoDBは、JavascriptのエンジンであるSpiderMonkeyを拡張した、Javascriptシェル？です。
なんで、JavaScriptの記述でデータのが取得が可能です。

$ mongo
MongoDB shell version: 2.2.3
connecting to: test
&gt; show dbs
local	(empty)
test	(empty)
&gt; use test
switched to db test
&gt; db.test.save( { a: 1 } )
&gt; db.test.find()
{ "_id" : ObjectId("51285b019fc2311ea475b159"), "a" : 1 }

$ mongo

MongoDB shell version: 2.2.3

connecting to: test

> show dbs

local (empty)

test (empty)

> use test

switched to db test

> db.test.save( { a: 1 } )

> db.test.find()

{ "_id" : ObjectId("51285b019fc2311ea475b159"), "a" : 1 }

AppFog tunnel Error 600: Not enough memory capacity, you’re allowed: 2048

Feb 13, 2013

AD:

In AppFog, when you connect Database you will use tunnel but I could not access today.

$ af tunnel
1: database_name
Which service to tunnel to?: 1
Deploying tunnel application 'caldecott-ap-aws'.
<span style="color:red;">Error 600: Not enough memory capacity, you're allowed: 2048</span>

$ af tunnel

1: database_name

Which service to tunnel to?: 1

Deploying tunnel application 'caldecott-ap-aws'.

<span style="color:red;">Error 600: Not enough memory capacity, you're allowed: 2048</span>

So I searched why and then I found out the problem.

How I fix

When using af tunnel, it uses 64MB that why error was “Not enough memory capacity“.
I just went to Console Page in AppFog and then reduced memory from one of App.

$ af tunnel
1: database_name
Which service to tunnel to?: 1
Getting tunnel connection info: OK

$ af tunnel

1: database_name

Which service to tunnel to?: 1

Getting tunnel connection info: OK
