Link: Pollution in 1.0.0.0/8

IANA has recently allocated 1.0.0.0/8 to APNIC, which hascaused a certain amount of concern that it is 'polluted' bypeople already using it for various reasons. Pollution in 1/8 is a report from RIPE Labson what happened when they announced routing for some bits of it as partof their debogonising work .

This is clearly going to be what they call 'interesting'.

How to destroy people's interest in updating documentation

Here is one of the less obvious perils of outdated documentation:

Suppose that you have some documentation that is out of date, but not inan obvious way; for example, you have an out of date network layoutdiagram . Since it's not obvious you don'trealize this right away, so you keep on updating the network layoutdiagram when you make changes to your actual network.

Except that faithfully updating an inaccurate network layout diagram isrelatively pointless. When you realize that it is incorrect, you are


Outdated documentation is especially risky for sysadmins

The obvious traditional risk of outdated documentation in all its formsis that you rely on it and go wrong somehow; you trust the comments inthe source code and write your new code accordingly, and your changesdon't work. I think that this risk is especially acute for sysadmins,for two strongly related reasons.

First, much of our documentation tends to be about procedures, notsimple information. Following what is actually a wrong or incompleteprocedure is a great way to create spectacular failures on the spot.Worse


屬於我們的懷舊

走一轉youtube,或是上一上論壇之類,我們不難發現大家很喜歡懷舊,但不是遠古的石器文明,不是歷史書裏的風雲人物,而只是自己的童年。重看一遍小時候看過的動畫,聚集同輩互相提起那一年暑假的卡通劇情,然後再三肯定大

在網吧打機至晨光初現,無聊地喝了幾罐啤酒,阿亮呵欠連連的回到家裏,準備進入夢鄉。

在商場做清潔工的媽媽正準備上班,像人肉錄音機似的問著天天重複的問題:“點解你出咗去成晚呀?點解你又飲酒呀?你幾時先肯搵份

當你哭時

當你哭時,

我很心疼很心疼,

因你哭而想哭。

不懂說窩心的話,

但想你知道,

我總在你身邊,

即使十年二十年三十年過去。

我會讓你一天二十四小時都找到我,

聆聽你最微小的事。

你是我的蘇眉,

直到永遠。

肚腩和時間

我平均每天運動超過一小時,包括跑步、舉重、練拳等,除了出外旅行,從不間斷。這當然是為了強身健體,保持活力充沛,而且運動多了,連腦筋也靈活一點。不過,我其實還有一個膚淺的理由:我不想自己長出大肚腩來;只

What charging credit cards doesn't prove

Every so often, commonly in the context of SSL certificates, someoneputs forward the theory that charging money for things makes thecustomers somehow more identifiable and reliable than giving it topeople for free (with the same other authentication of customers).After all, so the theory goes, when you give people something justbecause they have a particular email address, that's not much, but whenyou've charged their credit card, you have a lot more confidence intheir real identity.

This is wrong.
