ビジネスソフトウェア開発の世界には、Microsoftの.NETツールセットとJavaの2つの大きな流れがあるが、ここへ来て、3つ目の潮流が生まれる可能性が出てきた。
企業コンピューティングの主役の座を狙っているのは、「LAMP」と呼ばれるオープンソースソフトウェアスタックである。LAMPには、LinuxオペレーティングシステムやApacheウェブサーバ、MySQLデータベース、さらにスクリプト言語であるPHP、Perl、Pythonなどが含まれている。
偶然にも最近LAMPなお仕事が増えつつある環境におかれたので大変タイムリーな記事でした。
僕はもともとVBな人でASPなんかを触ってたわけで、言うならばWISV (WindowsOSでIISサーバー、SQLサーバーで言語にVBScriptでASPって感じ。こんな言葉はありません。)な人だったわけです。もちろんその間もJavaやPerlやPHPなんかも触ってましたが、マザーランゲージとしてはVBだったんですね。
当時、Microsoftのプラットホームを選んだ経緯は色々あるんですが、独立を契機にLinux + Apache(Tomcat) + PostgreSQL + Javaというプラットホームに移行しました。まぁこれが表題にあるLAPJなわけです。(勝手に命名してますが)
僕の場合、この環境に移行したときに大きかったのがもちろんプラットホームのコストダウンです。ノウハウを得る金額と時間は別にして、ソフトウェアにかかる金額が限りなく0になりました。しいて言えば、Visual Studioに代わるよい開発環境がなかったため、快適なコーディング環境を得るにはEclipseの出現を待つ必要がありました。
ちなみになぜLAPJな環境を選択したかというと、コストを0に近づけるといった意味でOSにLinuxを選択したのは必然な流れでした。そうなるとWebサーバーとしてはApacheということになります。
当時は企業の社内システム開発が多かったのでDBには読み取りパフォーマンスよりもトランザクション管理などに一日の長があるPostgreSQLを選択しました。
選択の順番の前後はともかく、言語にはJavaを選択したのですが、これについては・・・趣味です。
Javaのサーバーサイドアプリケーションとなるとアプリケーションサーバーが必要になりますが、J2EEを覚えるつもりはなかったのでTomcatを選択しました。
こんな感じで始めたわけなのですが、特に不満もなく淡々と過ごしてたわけですが、ここにきてLAMP環境に大きな魅力を感じています。
僕の場合、記事中にあるようなコスト問題はないし、企業による機能追加の問題もLinuxにしろ、Perlにしろコミュニティ間での意思決定に時間がかかったりするわけで、あまり関係なさげです。
では何に魅力を感じているかというと、一言で言うとGeekな香りです。
このことはCPANを覗いてみると一目瞭然です。Net::AmazonだとかNet::GoogleだとかApache::iTunesだとか、見てるだけでウハウハです。
以前はPerlの型やスコープのあいまいさ(VB使ってて何を言うと言われそうですが)や、MySQLの機能の乏しさやなどには辟易させられることも多かったのですが、一旦触れてみるとそこには一種の潔ささえ感じられてきます。
というわけでこれからは個人の趣味でも積極的にLAMPしてみようと思います。
でもJavaも好きだからこっちも追っかけます。
二兎追うものは一兎をも得ずにならないようがんばります。

There are electrostatic air purifiers that do not even have a filter like the others. You take them apart and wash them. The Oreck 2000 is an example. You do not ever buy filters for it.

Excellent information here. This blog post made me smile. Maybe if you throw in a couple of pics it will make the whole thing more interesting.
Just my 2 cents, but your blog posts will look much more interesting if you can put in some pictures.
It takes more thought to come up with a good blog comment then a bad one. For instance, it takes much less brain effort to say “you suck” than to say “I profoundly disagree with the simplistic drivel that has been touted on this networked opinion delivery system.” As evidenced by the number of moronic comments that are left on various blogs, it appears that the majority of blog readers have the cranial capacity of cattle who spend a lot of time defecating in the same pool they drink from.
That looks very good yet i am just still not so certain that I like it. Anyway will look more into it and decide for myself! :)
Are you looking for a guest writer? If so, please let me know. I am sure we can help each other out!
