• 谈梦

    经常有人说现代科学不能解释人的思维活动,所以还需引入灵魂概念。当被问到具体什么问题现代科学解释不清,以至于灵魂都可以被当作不错的解释的时候,梦的问题就往往被列举出来了。这篇文章就试图把现代科学对梦的有关研究大致说说。

  • 人生来就是无神论者么?

    Posted on: Wed, 09/12/2007 - 05:00 By: Huahai

    有的嫉妒徒总是说人生来就是无神论者。言下之意,就是说有神论者是更高级的,是已

    首先,说人生来就是某某论者,在熟悉现代科学的人看来是荒诞不经的说法。人可能是

  • 略论英美国民宗教观念差异的原因,顺便谈谈中国

    Posted on: Sun, 09/02/2007 - 02:27 By: Huahai

    刚才有网友转贴英国卫报的文章(1),说民调显示,英国多数人(82%)认为宗教的害处 多于好处,同时有三分之二的英国人认为自己并不虔信宗教。有意思的是,英国是有法 定国教(Anglican)的国家,英王本人同时也是国教教会的教主。反观美国,宪法是明 文规定政教分离的。而且,美国重要的国父,如杰佛逊和富兰克林,都是自然神论者( Deist),并非嫉妒教徒。但是,在现代美国,宗教,特别是嫉妒教的影响力是无处不在 的。美国多数人(80%)是嫉妒徒,40%的人自称经常参加教会活动(2)。美国政客如 果不自称为虔诚教徒,是几乎不可能在政坛上取得成功的。照理说,英美语言文化都一 脉相承,相互影响,为什么在国民的宗教观念上差异如此巨大?

    对这个英美国民宗教观念差异的根源问题,我的假设是,这是两国哲学思想上的差异, 特别是在教育思想上的差异造成的。这儿的教育指从幼儿园到高中(K12)的学校教育 。到了大学,大部分人的人生观都大致定型了,大学教育对基本宗教观念的影响不如 K12教育大。而且,我觉得英美大学教育差异并不大。美国的大学原本就是造搬欧洲大 学的。美国大学教授和美国普通人的观念差异简直就如火星人和地球人的差异,根本就 不能作普通美国人观念的代表。 对现代美国的K12学校教育影响最大的人物,自然要数杜威了。我所在的这个大学的一 些搞K12教育研究的同事是言必称杜威的。一个同事甚至连办公室的门上也贴着"What would Dewey do?"的铭文,俨然是把杜威当耶酥来看待的(3)。

  • 我为什么把Christianity翻译成嫉妒教

    Posted on: Sun, 09/02/2007 - 02:24 By: Huahai

    主要有3个原因。

    首先,我一直对"信达雅"的翻译准则中的"雅"很不满。"信达"即可,追求"雅"就是人为 地加入原文中没有的东西,与"信达"是矛盾的。事实上,很多英文本身是很不雅的,非 要翻译得很雅,就有误导读者的嫌疑。我个人认为,这种美化外文的习惯也助长了一些 人盲目地崇洋媚外的心态。相反,如果不盲目追求"雅",而是正确反映原文自身的味道, 那才是好译文。比如,傅东华翻译的<飘>,就把握得很好,显然比后来的译本好多了。 “郝思嘉”、“白瑞德”、“饿狼陀”和“曹家屯”翻译得都很传神。

    第二,Christianity只是来源于一个人名Christ,本身没有意思,翻成基督教,就赋 予了它本身所没有的含义:"基"有根本之意,"督"有权威之意,"基督"就是"根本的权威", 这个翻译就不是"信达"了。 而且,一个外来宗教的声誉是要自己行事来争取的,靠名字来"占欺头"是投机取巧,是 行不通的。别的宗教,伊斯兰,佛,喇嘛,萨满,等等,都是音译,堂堂正正,公平竞争。

    第三,鉴于基督教的名字已广为人知,要拨乱反正,就只好在这个名字的基础上改。"嫉 妒教"就是一个很好的选择。其音与基督教类同,不会引起混淆。更重要的是,其意也与此 教的主旨相符。为何如此?且听我慢慢道来。

    Romans 3:10 As it is written, There is none righteous, no, not one:
    罗马书3章10节:就如经上所记,世上没有义人,一个也没有。

  • 自由意志是人的物质特征的一个体现

    Posted on: Sat, 09/01/2007 - 05:00 By: Huahai

    当代无神论首席发言人道金斯在一个辩论[1]中说他不关心自由意志,自然就让人觉得落了下风。其实,这个问题的回答可以很简单:所谓自由意志,无非是人作为物质的一个必然表现。

  • Putty as a Chinese Telnet client

    Posted on: Wed, 11/02/2005 - 00:42 By: Huahai

    How to display Chinese characters correctly on a Telnet client running on a non-Chinese version of Windows machine? Web browsers today support whatever character encodings, this is not so with Telnet client. If you make a Telnet connection to a Chinese server with Windows telnet client, you will most likely see strange characters on screen.

    Solution: PuTTY.

  • Dual Head with Xorg on Thinkpad X31

    Posted on: Sat, 10/15/2005 - 05:00 By: Huahai

    My Thinkpad X31 got a small 12.1 inch screen, so I decide to increase the screen real estate by adding an extra monitor. The idea is that the LCD and the CRT monitor will display different part of the same desktop. This dual head solution is sometimes called 'Xinerama' in X terminology.

  • LCD and X DisplaySize

    Posted on: Sat, 10/15/2005 - 05:00 By: Huahai

    Under Linux, have you ever felt that stuff on your brand new LCD display looked blurry, especially with small font sizes, the words start to look fuzzy after a while? Chances are that you did not set the LCD with its optimal resolution. There is an easy fix:
    1. Measure the actually size of your LCD display area in millimeters (mm). Use a ruler. For example, my small X31 screen measures 240mm (width) by 180mm (height ).
    2. Now check the values you have in your X configuration
    xdpyinfo | grep dimensions

  • Centralized authentication with LDAP + NFS + Samba (Part II: NFS)

    Posted on: Mon, 01/17/2005 - 05:00 By: Huahai

    NFS (Network File System) is an old Unix technology that enables a machine to mount a remote file system. This is desirable for centralized authentication, as the user can access the same home directory no matter which machine he uses.

    Server

    Install NFS server:
    apt-get install nfs-kernel-server

    Edit /etc/exports, put in lines such as

    /home *.dept.school.edu(rw,no_subtree_check)

    to export directories to allow machines on local network have access to /home and its subdirectories.

    Start the server:

    /etc/init.d/nfs-kernel-server start

    If you have a personal firewall running on the machine, you will need to configure it so NFS traffic can be served from this machine. On MEPIS Linux, go to Guarddog->Protocol->Local->Network File System - Sun Microsystems, and check the box, apply; For client, goto the Internet zone, instead of Local zone, check the same box. Since NFS is highly vulunrable for exploitation, you should make sure your whole subnetwork is behind a firewall.

    Client

    We would like to automatically mount the NFS volume when a user is trying to access it. am-utils, an automounter, will do this. Get and install it:
    apt-get install am-utils
    *use NIS: no

  • Centralized authentication with LDAP + NFS + Samba (Part I: LDAP)

    Posted on: Mon, 01/17/2005 - 05:00 By: Huahai

    Ok, what is centralized authentication? Why bother? Well, if each person in your home or organization uses her/his own computer only, no need for this. However, if you or your organization have a bunch of machines and people need to login to different machines at different times, you've got a problem. Do you want to setup an account for each person on each machine? What about people's files? People would like to have access to their files no matter where they login. For this kind of environment, centralized authentication is the way to go.

    I am setting up a centralized authentication environment for a small work group, it consists of 7 or so Debian Linux boxes, 2 Sun Solaris boxes, and 5 Windows 2k/XP machines. Since the budget is tight, I will use all open source solution for this setup, namely, OpenLDAP, NFS and Samba.

    The actual setup proved to be quite easy, but took us a few days to figure it out, mostly due to the scant documentation available. I hope this series of posts can help alleviate this problem. The first installment deals with seting up LDAP server and client on Debian Linux machines. Most of the steps assume you have root privilige.
