Hackers and Crackers

Today, we could not access the internet at our university.

The cause was unclear, and we could not use internet almost all day, so it was really inconvenient.

Someone might attack server of our university.

We (this may be applied only to Japanese people) often refer to a person who attack network system et cetera as a hacker, but this is not correct.

Hackers have a deep technical knowledge that is related to computers or network, and they use the knowledge for system improvement or problem solving.

In other words, hackers are good people.

Although hackers also refer to people who look at inside of computers, when accompanied by illegal acts such as unauthorized access, destruction or falsification, they are called crackers.

However, since hackers and crackers are often confusing, we sometimes refer to a benevolent hackers as a white hat hacker, and refer to a cracker as a black hat hacker.

Also, an especially good hacker is called "wizard" or "guru."

I sometimes hack Java, but I'm not villain.

ハッカーとクラッカー

今日は大学で、ネットワークが繋がりませんでした。

原因は不明でしたが、ほぼ一日中使えなかったため、とても不便でした。

何者かによる攻撃を受けたのかもしれません。

私たちは（もしかしたら日本人だけかもしれません）よく、ネットワークシステムなどを攻撃する人をハッカーと呼びますが、これは正しくはありません。

ハッカーはコンピュータやネットワークに関する深い技術的知識を持ち、その知識を活用してシステムの改善や課題の解決をする人たちのことを指します。

すなわち、ハッカーとは良い人なのです。

ハッカーは、コンピュータの内側を覗く人も指しますが、不正アクセスや破壊・改ざんなどの違法行為を伴う場合は、クラッカーと呼びます。

しかしハッカーとクラッカーは混同されることがあるため、善意的なハッカーをホワイトハットハッカー、クラッカーをブラックハットハッカーと呼ぶこともあります。

また、特に優れたハッカーは、ウィザードやグルと呼ばれます。

私は時々Javaをハッキングしますが、決して悪人ではありません。

I think that the distinction between hacker and cracker is not known here in the West either. Hacker usually has a negative connotation here as well. This was an interesting read!

Great job, kanotown-san!
Like nanacc said, "hacker" does have a negative connotation in the West. I don't think the term "cracker" is used much in the US--at least, I don't hear it much, and I'm a computer security guy. We do use "white hat" and "black hat" often, though.
