2006大事回顧 (其實係私事)

1. 兜兜轉轉,最後做o左空姐。當初點解會apply已經唔重要,最緊要係… … 呢份工係唯一一份,我冇諗過幾時要辭職。

2. 做o左Lasik。雖然有後遺症,反反覆覆都好唔到,甚至將來可能連身邊最親既人既樣都望唔清。但係,我冇

Link: Threads Cannot be Implemented as a Library

I've already linked to this in passing , but I'm going to rerun itas an explicit link. Threads Cannot be Implemented as a Library by HansBoehm makes the argument in its title:

We provide specific arguments that a pure library approach, in whichthe compiler is designed independently of threading issues, cannotguarantee correctness of the resulting code.

There is also a discussion of this paper at Lambda the Ultimate that may be interestingreading. On a quick skim of the LtU discussion thread, thisUsenet article


Solaris's impressive ABI compatibility

There are some things that Solaris is very good at; one of them isuser-level ABI compatibility (at least for basic programs). As anillustration of just how good it is, I only recently noticed that on ourSolaris 8 machines I am still routinely using some dynamically linkedprograms compiled in August of 1993 (which is probably when this groupstarted using Solaris machines).

I hadn't noticed before now because the programs hadn't really changedsince then (so I had no

A (Solaris 8) automounter irritation

Here's an automounter irritation that keeps biting us: on fileservers,the Solaris 8 automounter is not smart enough to notice when anunderlying /export/ mount point has been unmounted.

If it gets a request for the filesystem, it 'mounts' things anyways,which then fouls up various aspects of, say, remounting the realfilesystems. It is remarkably difficult to persuade the automounter tolet go so that you can restore things to normality, and you can't justshoot the entire automounter


Weekly spam summary on December 30th, 2006

The SMTP frontend died twice late Friday night, to my irritation.That said, this week we:

  • got 9,806 messages from 186 different IP addresses.
  • handled 15,551 sessions from 916 different IP addresses.
  • received something over 204,995 connections from at least58,611 different IP addresses.
  • hit a highwater of at least 6 connections being checked at once.

The message count is down dramatically from last week because this week


What can go wrong if your compiler is not thread aware

Courtesy of Pete Zaitcev ,here's a great example of what happens when optimizing compilers aren'tthread aware.

Start with code of the form:

struct a b;
b.pos = *ppos;ret = foo(&b, ..., b.pos);

Modern versions of gcc 4 on x86 will optimize the function call into:

ret = foo(&b, ..., *ppos );

(This is a less stupid optimization than it looks; ppos


A thought on the advance of X auto-configuration

That X needs a configuration file less and less makes it more and moreimportant to have your monitor(s) powered on when you're powering on orrebooting a machine, because otherwise X won't be able to get the DDC information it needsto do most of that nice automatic configuration. A side effect of thisis killing off BNC monitor connectors, because you can't do DDC overBNC.

(Yes, I still have a CRT monitor at home, and until recently I was usinga


Firefox 快速轉換 Proxy 插件

Foxy Proxy

地震令到網絡癱瘓,相信各大 ISP 也正在實行「改道措施」,但網速難免受到影響。 Jan 提供了一些 Proxy 給大家使用。而 Firefox 插件 FoxyProxy 也許正合大家使用,它可以讓你方便地改變 Firefox 的 Proxy 設定外,而且也可以設定某些網站用某些 Proxy,甚至跟據
