A surprise to remember about starting modern machines

In the very old days you connected to Unix systems through serialterminals, which only had their getty processes started once init had finished processing /etc/rc .

In the old days you connected to Unix systems through rlogin(d),which was started through inetd , which was still started prettymuch at the end of system startup.

These days you connect to Unix systems through sshd , which is oftenstarted relatively early in the system boot sequence. This means thatyou can easily wind up logging into a machine that

如果思想是一瓶驅風油


我越來越覺得,澳門最詭異的地方,是我們不太重視“思想”,卻從來沒有人覺得這是一個問題。

“思想”兩個字,對很多人來說是很複雜的。你有沒有“思想”?你有沒有利用你的“思想”解釋、改變、創造、豐富這個世界?

人機合一

Flesh and Machines 《我們都是機器人:人機合一的大時代》 (Flesh and Machines: How Robots Will Change Us) 是由 MIT 人工智慧實驗室主任羅德尼‧布魯克斯 (Rodney A. Brooks) 所寫,以他本身的經驗,去講機器人的開發史,遇上的難題,現在的情況和未來的展望。我看的相關書


Some problems with iSCSI on Solaris 10 (on x86)

The basic operation of iSCSI goes something like this:

  1. poke things to discover what iSCSI targets you have available, then
  2. login to each target, creating sessions and discovering whatiSCSI devices (eg, disks) they have available, then
  3. talk to those iSCSI devices over the sessions you've createdto actually do things.

There are three sorts of discovery: static configuration, SendTarget,and iSNS. Static configuration is the least convenient, because itrequires you to know the target's full iSCSI name as well as its


The VPN routing problem

An end node machine connecting in through a VPN has two IP addresses;one IP address that is inside the VPN (call it I), and its normal IPaddress outside the VPN (call it O). The outside address is sometimescalled the wild side address, because it is accessibly by the wildInternet.

A lot of writing about VPNs assumes that I and O are disjoint from eachother, effectively on completely isolated networks; I talks to thecorporate network behind the VPN and only the corporate network,


蒲之二三事 / 內向

介乎林夕與朴贊郁

有些歌是可恨的,明明從頭到腳趾尾都不認同不喜歡而且很肯定它過時得要命,但它紅極了到處播之餘還會真的,聽進前意識裡去,無端端發現自己真的在哼、不哼出來心裡在響更糟。煩、陰濕、manipulative、死纏爛打。光良的〈童話〉

Quality Solaris 10 software:

Very interesting things can turn up while you are testing Solaris 10iSCSI support make sure it behaves nicely in the face of dead logicaldisks. Like, say:

# format
Searching for disks...
Mode sense page(3) reports nsect value as 63, adjusting it to 0
Error: can't open selected disk '/dev/rdsk/c2t1d0p0'.
Arithmetic Exception - core dumped

(I was running format to see what disks it still saw; format


巴士奇遇

銅鑼灣某個巴士站。

一條長長既人龍。

女:「咦~ 做咩要人地搭巴士喎,我情願搭的士。」

男:「點解呀?」

女:「頂住對腳鬼死咁辛苦。」

我望一望個女仔。

佢著住一對兩吋高既短boots。

矮我半個頭。

我... 身高五尺一。

我好
