Gmail POP3 support!

Google recently started introducing free POP3 and SMTP e-mail access access to GMail users. However, their instructions for Mail were not very accurate, so I thought I'd share how to really get up and running with this new feature.



Please note that not all accounts have POP3 access yet, as it has only been introduced to a handful of users. To see if your account is POP-ready, log in and look for "New Features!" in red on the top-right of the window. If it isn't, this hint won't be very useful to you.


  1. Open up Mail.app and press Command+Comma to invoke the Preferences window.

  2. Switch to the "Accounts" pane and press the + button in the lower-left corner.

  3. Under "Account Information", fill out the following information:
    • Account Type: POP

    • Email Address: username@gmail.com

    • Incoming Mail Server: pop.gmail.com

    • Username: username@gmail.com

    • Password: password


  4. Select "Add Server..." from the "Outgoing Mail Server (SMTP)" pop-up menu. Here are the details for it:
    • Outgoing Mail Server: smtp.gmail.com

    • Server port: 465 or 587

    • Use Secure Sockets Layer (SSL): Yes

    • Authentication: Password

    • User Name: username@gmail.com

    • Password: password

    • Dismiss the window by pressing "OK."


  5. Back in the "Accounts" pane, switch to the "Advanced" tab and check the box marked "Use SSL" towards the bottom.

  6. The rest of the process is short and sweet, and merely involves changing your Gmail preferences to enable POP access.

Epigenesis!

From: http://www.gender.org.uk/about/03gene/38aepgen.htm
A very good and interesting article on epigenesis!
---------------------------------------------------------------------------------------
On the 4th. August, 2003, the New Scientist published a report entitled "You are what your mother ate, suggests study"(1) The study was one about epigenetic gene regulation, which the New Scientist referred to as "a weird form of inheritance." This leads us to wonder what we mean by inheritance in a genetic, and, in most people's minds, Darwinian, context.

The word epigenesis originated in the eighteenth century in the debates about preformation. The preformatist view held that "all major structures of the adult are already preformed in the sex cell . . . ."(2) Epigenesis held that "morphological complexity develops gradually during embryology from simple beginnings in an essentially formless egg". At that time "that complexity must be imposed from without by some vital force . . . ."

Once DNA was discovered, the meanings changed slightly, for the organism could be said to be preformed by the set of instructions held within the genetic code, while, in a more secular age, epigenesis was held to be the effect of the environment in shaping the way those instructions were read. But this would seem to be more to do with ontogeny, the life history of the individual from conception, than phylogeny, the history of the species.

We, of course, inherit much more than our genes. We inherit our family's wealth and its social position. If we live in a family of gluttons, regardless of any genetic predisposition, we may become obese. The environment we grow up in, and in the womb, may affect our development, even the way our genes are expressed, in ways that are still not fully understood. But to suggest that such environmental influences are passed on to future generations carries an air of Lamarckism.* We will, therefore, use this study(3) as an example to tease out the word's actual meaning.

The study concerned mice of a particular colour called 'agouti' which occurs because of a yellowing of otherwise black hair, due to the production of phaeomelanin instead of eumelanin, producing the brown colour of wild-type mice. The loss of this effect in black mice is caused by a mutation, a so-called transposable element in a particular gene. Such transposable elements, colloquially known as 'jumping genes', are quite common in mammals and, for instance, constitute over thirty-five per cent of the human genome. The majority are normally silenced by a process called methylation. A particular diet for a mother can affect this methylation in her offspring, and hence their coat colour.


Methylation

 Well and good, but this seems no different from, for instance, a child inheriting its mother's heroin addiction.

The germ cells in mammalian mothers are formed very soon after conception and then remain dormant until puberty. Accordingly, the researchers took dams that were known to be virgin, and fed them a vitamin-rich diet for two weeks before they were mated. The effect on coat colour and presence of methylation was observable in the young, and persisted until adulthood.

Moreover, even though they ate a normal diet, the effect was still, to some extent, observable in their offspring, the 'grand offspring' as it were, of the original mothers, but would be expected to disappear in future generations.

The point of this particular study was to show that dietary interventions in humans may have unintended consequences, not simply metabolic, but genetic, on, for instance, the susceptibility to disease.

For our point of view it illustrates that the genome is less rigid than Darwinian theory would predict. The latter gives a view of the genome unchanging across many generations, perhaps thousands of years - such change depending on random mutational events. Here we have an example of the flexibility (and self-regulation) of the genome as it responds to the environment within generations.

Some instances last for hundreds of generations however, without obviously coming about because of the external environment, and the word epigenesis has come to mean more literally "over" or "around" the gene. In other words, influences on genetic function that are transmitted through mitosis and meiotis, but without changing the DNA sequence. Examples of this are the inactivation of one X chromosome by methylation in females, and a newly discovered phenomenon by which one of a pair of otherwise identical genes may be imprinted such that it is activated or inhibited by one of the parents.

Some authors look to epigenesis as a mechanism which enables adaptation and speciation to occur more quickly than by the orthodox Darwinian route.

* In the eighteenth century, many people were attempting to explain evolution. Lamarck proposed that it was due to "Inheritance of acquired characteristics."

由达芬奇密码想到的

由达芬奇密码想到的
上次看完达芬奇的密码之后,就对数学的完美性和关联性,以及数学完美性在现实中的应用有了一定的感慨,不过今天在复习developmental biology的时候,对这个问题就更加佩服了。
0,1,1,2,3,5,8,13,21,34...
这是著名的Fibonacci Series。Sn=Sn-1 +Sn-2.
但是大家有没有发现Sn-1/Sn是多少?
0/1=0
1/1=1
1/2=0.5
2/3=0.66667
3/5=0.6
5/8=0.625
8/13=0.6154
13/21=0.619
21/34=0.6176
......
好了,大家或许都猜到了,这个数值最后趋向与黄金分割数(近似于0.618).
同时Fibonacci Series和植物学里面有名的Contact Parasticies之间的关联性更加令人惊奇。
parasticy pair刚好遵循Fibonacci Series.
angle of divergence=360?{1-(Sn-1/Sn)}=360(1-0.618)=137.5.
hoho.....这个数字可不简单。想想protein alpha helix里面的phi, psi angle就会有新的发现。

Shiira is based on Safari

     Before last night, i only knew that Shiira is based on the Apple WebKit engine. But a incident tells me more about that.
     Days ago, I downloaded the Safari 1.3 DP 5.(developer Preview 5) and get a try. everything is fine at first. But then from the day before yesterday, i just cannot open the gmail website. I just gives me a blank page after loading.
     At first, i havent thought about  the Safari 1.3 staff, but i am sure it is due to the browser. Then i tried Shiira, either Does not work! This can only tell me that it is not my browser's problem but the gmail server itself. So i was out to post a thread on sinomac.com.
    Luckily i get a inefficient Chinese Input program. Before i finish that post, one idea jump into my mind: maybe it is due to the "DP5"?
    Ok, the followings are easy le. Uninstall safari 1.3 and reinstall 1.2. Gmail web page is back! Shiira is also back to the track!
    It seems that Shiira is directly based on the Safari that i get in my OS. If this is the case, then there should be no compatible difference between two.
    Need more information on web browser engine!

Mac web browsers!

There are a batch of web browser available for Mac OS X. Here are some of them. If you are interest, just download them and have a try. They wont burst your dear mac......
For me, i use shiira. Safari is really a good web browser for most macs. But not enough for me, because it does allow "Only Tab Browser". Shiira has that option and almost all feathers safari has, so i choose shiira(it is a Japanese project).

National building to become to global city-state









National building of Singapore to become
a global city-state



Yang Guowei





Materials used:



1.Singapore: The City-State
in History/Yong Mun Cheong



This article tries to figure out a
propel name for Singapore by comparative studies on other City-state in the
history like Swiss cities. Issues like methodology, definition are put on the
table. Some key elements, like economy, ethnic beliefs, politics and geography,
are deeply discussed on their contribution to form a city-state. At the very
last part, the author touched a little bit on destiny of City-State and shows
his worry on Singapore’s further. Lots of materials are referred, and they
really play a dramatically role in this article and make the author’s thought
very clear. Above all, the author concerns more on structural issues such as
social and political. But in my opinion, in the context of Singapore, it is
more import to study the “City-State” in a historical way, more generally,
whether Singapore is ready to be a City-State. More will be touched in later
discussion.



2.The National Past and the
Writing of the History of Singapore. /Albert. Lau



This article is more historical
than the first one. It straightly comes to the key point of Singapore’s
history: how to defined Singapore’s history and how to write it?



The author studies a lot of
different thoughts on Singapore’s history, from timelines issue to methodology
issue. By doing so, we can get a general idea of the history literature, both
temporal and spatial. In dealing with the history between 1819-1965, the author
uses “colonial past” in order to make distinction with the “National past”. In
his opinion, some historians have messed up these two terms. The way we write
our history depends more on our purpose, that is: by learning such history, our
fellows can fell more to be Singaporeans,?
and Singapore is more like a nation.



3. Singapore’s Quest for a
National Identity: The Triumphs and Trials of Government Policies. /Hussin Mutalib



This article focuses on
Singapore’s national building. First of all, the author issues the necessity of
national identity to a community, especially for those with short history but
complex cultural compositions, like Singapore. Then he turns to analyze all
policies that Singapore government made, by looking their backgrounds,
purposes, and effects. Of course, he also gives some advice like legislation on
anti-discrimination laws, etc.



Introductions
and guideline:



In this article, I will generate a
general idea about Singapore’s history and national building issue by studying
some literature materials plus my own thoughts.



The general guideline is:



?A Global City-State should finish its national building----àA
common identity is important for national building. ------àHistory
is very important to generate a identity + Ethnic marginalization is a big
issue----à
have a good way on dealing with history and different ethnic groups.



A reverse way is like this:



Singapore hasn’t found a way on
dealing with history and ethnic diversity----àit is very difficult to
build a common identity for all ethnic groups----àSingapore hasn’t
finished its national building-----àSingapore is not a
State---àSingapore
is not a Global City-State.



Main
Discussions:



Singapore, as it has achieved such
rapid economy development after its detachment from Malaysia in 1965, more and
more people show interest in
this tiny island. Singapore, though small in size, has a profound influence on South East Asia.
Being international trading hub and local transportation node Singapore is
deemed to be a global city for trade and business. In my view, however,
Singapore cannot achieve economic success without a strong Government and a
charismatic leader to hold people together. Singapore is indeed on the way to
become a global city state, and I found out that Government is in for racial
harmony and is addressing the issue of poverty all the time. All the effort
made are for only one purpose that is bonding people with different origins
together to become fabric of a nation.



A common identity is important for
a certain community. You cannot
imagine any group of people without certain common identity
to be together as a nation. A
common identity defines the basis of membership within a political community.



In the context of Singapore, people here share the same future, but different history. Different ethnic
groups come from different
backgrounds; they worship different religions as well. In this multi-racial and multi-cultural island community, many
different approaches can be used for
national building. One of them is Dominant-recessive approach. Another is unity-in-diversity approach and the latter
one has been adopted by
Singapore government.



Singapore is not the only country
that is facing multi-racial problems, situations in some other countries may be even worse. There are 56 different races in China. Russia has 130 different races! One
similarity between these two countries is the dominance of one racial group, The Chinese in China and
The
Russians in Russia. They are playing the dominant role in
determining country’s politics and in
some other key
areas. In other words, they make the rules, so that other minorities have to follow.



In the context of Singapore,
although Chinese is already majority,
it is very much imprudent for them to overshadow other races. Because from the regional
prospective Singapore is only a small polity in this region neighboring
powerful Muslim countries.



Another model is the
unity-in-diversity model.
Singapore Government is trying
to create new common identity that is neither
Chinese nor Malays nor Indians
but Singaporean, which is for
all people living here; no matter
which racial group you are from
. Together
they will sing Singapore National Anthem, and together they will take a pledge
to achieve racial harmony. The Government of Singapore has indeed done a
marvelous job uniting people from different backgrounds under a same Singapore
Flag.



In recent years, some sociologists have found out that many young
Singaporeans have little knowledge of the history of Singapore and the root of
themselves. The Government has realized the seriousness of this problem and has
begun to promote traditional activities, but there are still much more things

needed to be done. As said
by PM GOH, “as Singaporean have more and more money, more and more Singaporean
move to Australia.” Even though people here call themselves Singaporean, the
main point is not the name itself. The point is how to let people here realize
they share the same future, and they have to rely on each other to realize it.



One key point in the national
identity is the history. “Nations without a past are contradictory in terms?.
What makes a nation is the past, what justifies one nation against another is
the past?”Said by E.J. Hobsbawm. History is Critical in defining the Nation and
justifying the government’s endeavors. So how to define and describe the
history becomes a big issue.



?“Modern Singapore began in 1819, nothing that occurred on the
island prior to this has particular relevance to understanding of the
contemporary scene[i]”. Such kind
of thought is raised here and there. Is this really the best or most propel
way? Is it reasonable to ignore the pre-1819 history just because it has “no
particular relevance” to understand current issue? How about the effect that
Chinese Traders made date back to 14th century? How about the
relationship between Singapore and other Malacca port cities? It may seems not
important to the colony powers, but this section of history is particularly
important for local ethnic groups like Chinese or Malays. Only from it, they
can know where they are from and what the historical reason is for their
ancients to locate themselves here. In this sense, it is essential to define
Singapore history more than the colony period.



However, debates on such issues
seems have puzzled the Singapore government. Even worse, the worries of pulling
the community even apart by locating the “Diverse root history” also play a key
role. “What if they are even marginalized from others after knowing their
distinct histories?” it seems that Singapore government want to melt different
ethnic groups by weakling their own roots and creating a “common root” for all.
It is achieved by emphasizing the war, vulnerability and ‘Battle Royale’, which
refers to the fight between stouthearted nationalists and
communists/communalists (1950s & 1960s)



Another issue is the dependence of
Singapore history on others’. Singapore’s history is always affected by
external events, variables and cycles and always outside of the control of
locals. Great power is essential for Singapore to survival and Singapore
remained one part of Malay world for countries. Over emphasize on this is
really not a good idea. The only thing can be done is trying to concern on the
formation of this community, how did their ancients overcome the odds, how is
the process this island and people here differ from others. Let people know how
they become Singaporeans is more than an academic issue.



In the sense of national building,
Singapore is really not ready to be a global city-state. The process of
globalization goes along with the national building.



To be global, you first must be
“One” but not “mess”. The reason of globalization is still self-concern, it is
very important to know whom you are and for what you are struggling. All people
must hold the same civil value when they go global. What is the difference between an American and a
Singaporean?These kinds of
questions become even more strategically important in this globalization stage.



“Global city-sate” is a city-state that is global. There is
no doubt that Singapore is global enough. Singapore has a big population
transmission, has rapid and well-constructed transportation and is the main business
center.But is it a city-sate?
Following the definition by Arnold Toynbee, a city-sate is a state in which one
city preponderate or in which one city is so dominant that the rest of the
state would not challenge its paramountcy. In the context of Singapore, there is
no “rest”. Singapore is just a city. As the identity of Singapore is still
under “political joke[ii]
stage, how can you call Singapore a state or a nation? Rather, you may call
Singapore a city-country. Country is significant different from nation. Country
is more like a geographical term; meanwhile, nation is more cultural and
political. If you are not ready for, but already on the way to be global, the
probable issue you will face is the self-lost. After staying in the global
stage for a long time, you forget whom you are, where you are from, even worse,
where you will go.



Conclusively, history, especially
those before 1819, is statically important for different ethnic groups to
locate their own root. Only after you know who you are, you can hold hands with
other ethnic groups and join together to be a nation. Same strategy on
globalization, it is essential to complete the formation of nation before going
for global.

终于可以贴图片了!

自从用了mac之后,屡次催着wuvist修改后台来支持safari,终于他也提供了一个text文本模式。但是自从这个模式诞生之日起,就一直是只有5cm长,1cm宽,怎么可能在这里写东西,虽然后来有一次wuvist 通知我已经搞定这个问题,当时我也测试了,但是后来有是老样子,而且在这种模式下似乎不能用html code.. 害的我的那篇upgrade harddisk的文章有图无法贴。

今天一个偶然,绝对的偶然,我点击了切换模式,然后点击了html,

哇。。。。竟然可以使用!!!!!终于可以贴图了。。。所以我顺便把upgrade harddisk的图加上了。

Ibook Harddisk upgraded!

虽然这样会很麻烦,每次要自己添加html code..但是至少比无法贴图和连接好的多。。。。

我记得很久以前,我也点击过这个html的按钮,当时好像不能用。。。。

How to Backup your Mac OSx system!

when i was doing my hard disk upgrade. i found that my mac os x 10.3 installation disk is damaged and some of its "core file" can not be read, but the "installer" and "disk utility" work well. then i get this idea"it is really necessary for me to backup my system in my hard disk!". i did find a "image" option under the restore tool. but i didnt know how to make a disk image at that time.



last night, after finishing my damn lsm 3233 lab report. i decided to have a try on that. then i found that it is really simple!




1.boot from installation disk,choose disk utility under installer menu.



2.choose the system volume that you want to make backup image.



3.press "new image" button



4.create a name for that image.(panther.img). choose the location that you want to put this image(i think it has to be another different volume instead of the system volume). you can do encryption if you like.



5. press "save". then it will take some time to save it.




the image will be same size as the used size of your system volume.




when you  someday want to restore your system. then



1.boot up from installaion disk. choose disk utility under installer menu.



2. use the restore tool. under the" source" box. press "image" and choose that "panther.img" you have saved before.  choose the volume that you want to put the system in under "destination". check the "erase the destination" option.



3. press restore. then it will take some time to restore.



4. when it finish, change your start disk and restart. enjoy your new system!




o. now i have that panther.img located in my second volume"Storage". wow.....
