在 BFSH 看到一本叫 Stand 的 Webzine，內容頗豐富，而整本 Webzine 是用 Flash 做介面，模擬一本書本的樣子，可以揭頁，有書籤等等，真的是名符其實「網上雜誌」。不過，我認為做網上雜誌，這種介面其實並不合適。

An explanation for the popularity of threads
Today, I had an insight (possibly an obvious one) about one big reasonwhy threads are such a popular and widespread method of doingconcurrent programming:
Threads are so popular because they are so easy to implement. I don'tmean 'to write programs in', because they aren't really; I mean 'toadd to languages and language environments'. Unlike other models ofconcurrent programming, adding basic threading to your environment oryour language takes very little work. So threading implementationsproliferate like weeds

我要 Popup!
現在設計網頁，一般都不宜用 Popup 視窗賣廣告，因為瀏覽器一般都有擋 Popup 的功能。不過，Popup 並非萬惡，只要專重用戶決定，Popup 視窗是很有用的。
在一些寫作的介面上，Popup 便很有用，開一個小視窗打字，背景可以開其他的參考資料。
Dropping packets versus rejecting them in firewall rules
There's a reasonably popular view that having your firewall dropundesired packets instead of sending ICMP rejections is 'moresecure'. It is not; instead it is 'more annoying'.
(Technically this is not quite true; in a very limited set ofcircumstances, dropping all packets for a host can hide someinformation from attackers. The flipside is that dropping some but notall packets usually leaks information about what you're screening.)
Dropping packets is more annoying because attempted connections haveto time out before
Weekly spam summary on December 3rd, 2005
I'll lead with Hotmail's spam numbers:
- four emails accepted, and I know for sure that two of them werespam.
- 239 messages rejected because they came from non-Hotmail emailaddresses.
- 24 messages refused because their sender addresses had already hitour spamtraps.
- 10 messages refused due to their origin IP address (5 in the SBL, 4in the CBL, and one from Nigeria).
The case for banning Hotmail entirely becomes more and morecompelling. It's probably time

How to do TCP keepalives in Python
TCP keepalives are do-nothing packets the TCP layer can send to see ifa connection is still alive or if the remote end has gone unreachable(due to a machine crash, a network problem, or whatever). Keepalivesare not default TCP behavior (at least not in any TCP stack thatconforms to the RFCs), so you have to specifically turn them on.(There are various reasons why this is sensible.)
In Python you can do this with the .setsockopt() socket method,using
