Slashdot: Spam from Taiwan

有2/3的廣告信是從台灣的網路上來的！由此可見大家對廣告信病毒和避免成為公害的心態實在是太消極了…。

不過就我的印象來說，我們學網上如果有發現 Open Mail Relay 都鎖卡要使用者修電腦呀；家裡的電腦中毒的時候，SEEDnet也有寄e-mail要我處理… 那，到底是哪個網路沒良心的使用者在寄廣告信呀。

PS 我絕對沒有用Link影射某大ISP沒有做好廣告信控管的工作XD

I was shock to know that there are two thirds of world’s spam mails are sent by Taiwan computers. People here just don’t have the sense to protect their own computers.

But being a person managing a small part of Taiwan Academic Network, we (MOECC) do monitoring our own net. I did once got email alert me to clean up my home computer from the ISP; So, What ISP just don’t care about the spam problem then?

Teamwork

Posted on by

In a teamwork environment, I take things personally. Way to personal than others do. I like and willing to pursue the feeling to be in a (then) successful group. I believe this kind of attitude/model leads to success.

Then it had become a problem. Since most of people I encountered didn’t feeling that personal to teamwork success, they refuse to do more than “finishing” the job. They done their share of the work only, or even MIA, leaving (people like) me to handle it.

Put it in Chinese with popular metaphor: 我只是在當好人，然後你們在消耗好人就是了。

Maybe it’s our problem, you know? To live a miserable life all the time when team up with others; to do things alone; to be the last one to turn off the light. The model is wrong, so wrong that I couldn’t take it anymore. I should stop being that personal to things, and make myself clear that I am not covering one’s ass.

Anyone who reads this post, please – see if you are consuming someone in the group/team you think you “belong” to.

Seeking other positions to be in a teamwork now – but it’s just sad to see groups I once believed in to fail and fall apart.

Wave Pocket Animation

這是用Maplesoft Maple做的波包動畫Demo，要看會動的版本請按All Sizes(警告：700k GIF)。從動畫可以看出來波包以群速度向+x的方向移動，而且隨著時間能量慢慢的散開。

相對於波包在物理中的重要意義，波包的數學相當簡單；近代物理中的物質波、電磁波波速與能量傳播的速度的關係都與波包有關係。

This is an animation generated by Maplesoft Maple. See it in action in the All Sizes page (Warning: 700k GIF). You can see it travels in group velocity, and the energy decays from time to time.
