Computer

Computer Literacy - or the mind for data processing with a computer :

• Programming skills :

  言語は 3 つは習得するもんだ.

  まぁ, この世の中のプログラミングを 1 つの言語で統一するなら, 今は Java がいいんじゃないかな. 仕様は美しいし.

  データ/リソース記述言語は, まだなんともいえないが, 構造化できる XML になればいいんだがなぁ.

  • オブジェクト指向 - Java で一応の完成を見た. デザインパターンが提唱されたが, どのように対象をモデル化してオブジェクトにするかについては人間が考え, UML のドメイン図, クラス図などを援用すべき.
  • (対人)エージェント指向 - 人間とのインタラクションを中心としたモデルで, MVC をはじめとする旧来のオブジェクト指向モデルに 異を唱えるものと言ってもよいでしょう.
• Database fundamentals : Learn and experience efficient information processing.
• Network management : Get valuable information and share it.

Easy steps to build a hardware

1. Case and Power Supply

   When you choose a case, you don't want to buy one that comes with a power supply. Those power supplies are usually assembled in low cost and perhaps going to break in a year or so. Buy a blank case and a separate power supply. Here are the major form factors used in PC:

   • Extended-ATX : multiprocessor server/workstation
   • ATX : mid-range computer with decent extension slots
   • Micro-ATX : compact machine
   • Mini-ITX : very small machine such as cube/box

   I recommend to use a power supply built with good electrolytic capacitors used inside that is made in Japan, e.g. Abee's Silentist S-xxxEA/EB/EC (not ED), Scythe's Gouriki 2, or Owltech's Seasonic series. Never choose cheap one like Zumax.

   'Electrolytic capacitor' translates to '電解コンデンサ', and 'made in Japan' '日本製' written in Japanese, respectively.

2. Video Card (Graphics Board)

   There's been a war between ATI Radeon side and nVidia GeForce chips since we entered this world full of 3D graphics. ATI has been rumored to be focusing on impressive graphics quality, but lazy on supporting their device drivers for years. I'm not sure the merger with AMD has changed the situation a lot.

   Vendor	Stream Processors	Bus Width	Memory Clock	Max Operation Speed
   NVidia	320u	448bit	2.xGHz	300-400 GFLOPS?
   AMD (ATI)	800u	256bit	3.xGHz (GDDR5)	500 GFLOPS

   If you go with nVidia, it is best to choose ELSA's boards or cards from mainboard vendors like Asus or Gigabyte.

3. Display

   Standard	Resolution
   HVGA	320x480
   WVGA	800x480
   SVGA	800x600
   XGA	1024x768
   UXGA	1600x1200
   WUXGA	1920x1200
   QXGA	2048x1536
   WQXGA	2560x1600

4. Operating System

   Linux is one of the most affordable operating systems in the world. Nowadays it has plenty of good distributions even for beginners like these:

   • CentOS - Boasted to be compatible with RedHat Enterprise Linux.
   • Debian - Great for both servers and clients.
   • Ubuntu - One of Debian's derivation that has a decorative desktop edition and a simple CUI server edition.

   Among those luxury Linuxens, I believe Debian offers the best balance of usability and interoperability.

Linux Memory Management

Bear in mind when using and developing softwares

• Data Entry + Data Processing = Computing

Games are the important measure

You can't just believe what is said in the evaluation corner like in magazine 'Famicom-tsushin'.

Versatility and Portability

Thought on Real Portability

• I want a meta language that you can collapse into the following languages : 普通のことばから書けて, 次のような言語に展開可能なメタ言語がほしい :
  • C, Java, PHP - class-based objects
  • Javascript, Perl - prototype-based objects
  • Object Oriented Pascal (OOP)
  • Functional language for AI (Scheme?)
• Lisp - for data processing in Emacs.
• Java - for Dalvik interface, although Android has NDK which can enable C native code programming.
• S-language expert system
• Javascript expert system
