PayPal Fee Calculator

ForeverGeek 看到:PayPal Fee Calculator,提供一個網站 PayPal Fee Calculator,為什麼呢:

My wife doesn’t do much on the computer other than email, but she occasionally sells a dog online or something and wants to use my PayPal account to get the money. But she always wants to charge the buyer extra so that if she asks for $100, she’ll actually get $100, not $96.80, after PayPal takes their fees. So anyway, guess who she asks to handle that and figure up all of that information for her…

So anyway, after doing that more than a few times for her, myself, and other people, I decided to make a site that would do it for me. So here it is.

果然是長輩,隨便註冊一個 domain 玩… 不過既然是老婆大人要用,花個幾塊錢倒是無所謂 XD 順便公開出來 (透過 ForeverGeek 讓大家看?:p) 讓大家爽一爽,再放個 Google Adsense 看看能不能撈幾毛 :p (啊啊,聽起來頗讚啊)

跟 chunhan 聊到短網址

剛剛跟 chunhan 聊到短網址 (ex: TinyURL0rz) 的事情,提到他目前的作法,發現目前這種作法,如果要搬到外面有提供 database 的 web hosting,大概也會被擋下來吧,資料庫實在太大了 :p

所以我跟他建議用 SQLite,相當好用的 SQL server,尤其 query statesment 其實不怎麼複雜的時候…

SQLite 用單一檔案作為 backend storage,提供絕大多數的 SQL92 語法。在官方網站上面有 Speed Comparison,你可以看出跟 MySQL 速度的差異…

(其實我覺得最變態的是 SQLite 2.x & 3.xports 都是怪叔叔 ijliao 做的 -_-)

Firefox 的 extension (unzip :p)

我一直沒有去研究 Firefox 的 extension 是怎麼做到跨平台的,本來以為是某種特殊的 binary (換句話說,需要 compile),今天突然想到 far 並不會 Windows Programming,於是就去抓了 0rz.netplugins 來看,先用 file 讀看看這是什麼鬼:

gslin@netnews [~/work/0rz] [19:17/W3] file 0rz.zip
0rz.zip: Zip archive data, at least v1.0 to extract

Good,unzip 後發現有個 .jar,這東西看檔名就知道要 unzip :p

進去翻一翻,發現是一堆 rdf & javascript (或者是一個很像 javascript 的 language),原來是這麼簡單 o_____O

看來我以前想太多了 XD
