想想自己除了第一支手機是NEC的外..

[Homework]It really bugs me!
Write two short paragraphs about someone bugs you. In the first paragraph, describe the situation. In the second paragraph, say why this situation is difficult for you and describe a situation you would prefer.
I can't stand it when I am sleeping, and someone calls me late at night. I can't fall asleep easily. If I awake from a deep sleep, I really hard to fall asleep again. so if you have something important, please call me earlier or later.
I've been this situation once. When I was sleeping my classmate called me at 2:00 AM. He told me he couldn't go to work the next day. I know that was very important, but at that moment I couldn't do anything for him. I asked him if he could call me in the morning next time? I had to tell my boss in the morning. If I called my boss at that time, he might kill me.

[筆記]Ubuntu 11.04 安裝KDE中文語系
自從升級到Ubuntu 11.04完後一直沒有機會使用到KDE的軟體..
最近發現了Korganizer這個行事曆軟體..
沒想到在使用Ubuntu軟體中心安裝完成後的操作介面居然是英文的...
雖然介面的英文沒有很難..
但有時需要進階一點的設定時就不是那麼順手...

1Gbps 是速度，還是寬度？
在網路上看到了這篇文章..
突然發覺我們在定義"頻寬"時是要使用速度還是使用寬度來做為單位呢??
這還真是個可以深思的問題啊...
1Gbps 是速度，還是寬度？
我們常常會用“快、慢”來形容網絡速度，這是很自然的事情。 比如你下載一個文件，在辦公室裡因為帶寬被很多人分去偷菜了，所以你花了半個小時才下載好一首歌；回到家裡，沒有人和你搶帶寬，一個人5分鐘就搞定了。 所以，用“速度快、慢”很貼切。
但科學的說，1Gbps 說的是寬度，而不是速度。 因為每個字節轉化成電信號後在線纜中的傳輸速度基本是相同的——光速。 好比一樣限速80公里的道路，一個是4車道，一個是1000車道，這兩個道路每小時可以通過的車輛數量就很懸殊了。 1Gbps 相對於4Mbps 的優勢就在這裡。

[筆記]VirtualBox釋放.vdi檔未使用的空間
使用VirtualBox在建立新磁碟時會有個"動態延伸存放"和"固定大小存放"的選項..
一般我們都會選擇動態延伸存放以節省實體磁碟的空間..
但使用動態延伸存放後的vdi檔並不會隨著虛擬磁碟內的檔案被刪除而跟著減少...
造成了vdi檔越來越大最後就和固定大小存放沒什麼差別了..

[筆記]Setting default umask in Ubuntu 10.10
使用Linux做檔案伺服器己好一陣子了..
一直有個問題就是不同的使用者上傳的檔案因為權限的不同...
其他的使用者就無法做讀寫的動作..
那怕是相同群組的使用者也是一樣...
其實這問題很早之前就想解決..

[筆記]Digital Signature 數位簽章
簡介
在資訊安全的原則中，其中非常重要的一環，即為不可否認性(non-repudiation)，假設在正常情況下，A 傳訊息給 B，之後就不能否認曾經傳過訊息，此即為不可否認性。
但這應該如何做到呢? 答案就是 Digital Signature(數位簽章)
Digital Signature 的使用情境大概如下：
假設 A 要傳訊息給 B，但是 B 要如何確認訊息真的是由 A 發送的呢?
此時只要 A 在發送前利用自己的 private key 將訊息加密，再傳給 B，B 再利用 A 的 public key 進行解密。

[筆記]Asymmetric Encryption 非對稱式加密
簡介
Asymmetric Encryption (非對稱式加密) 即是為了改良 Symmetric Encryption(對稱式加密) 的缺點而產生的。
在對稱式加密中，通訊雙方往來的訊息是由同一把金鑰進行加密；假設 A 與 B 通訊，兩個人必須有一把相同的金鑰；而若是 A 也要與 C 通訊，則 A 與 C 則必須擁有另外一把不同的金鑰；否則若是都使用相同金鑰，C 就可以解密出 A 要給 B 的訊息，相對的，B 也可以解密出 A 要給 C 的訊息，如此一來資訊在傳送就不再安全!
除此之外，還要防範金鑰被竊取的問題，只要通訊雙方任何一個人把金鑰洩露出去，也就破壞了原本建立的安全機制了。
因此，Asymmetric Encryption(非對稱式加密) 使用了一對金鑰(key pair)的方式解決了這個問題
