Password Reset: Who can tell me why?

It was quite mysterious that my site suddenly stopped working this afternoon. Followed by the previous experience that the incorrect configuration of plug-ins that damp the service of Word Press, I checked all the plug-ins initially but nothing wrong. Problems seems to be more serious since the website then indicated that errors occur when connecting to the database. I logged into the background but found no clue at all. Unlike the description from some site that the database was deleted by the 000webhost.com that it remained, but the PhPMyAdmin failed to work. I was getting fully puzzled on what was happening.

But things alway turn their tables in a flash, so do my site. Occasionally I signed into the MySQL and tried to reset the password, and my sites work again! it is really mysterious that how do my password changed?

Who can tell me why do this happen? I am getting puzzled…

Exercise for GRE Analytical Writing: Quick action or A Reconsideration?

This is an exercise for my coming GRE Analytical Writing section, if you are interested, please provide me some suggestions on how to improve the writing skills. The reason why I upload them here is because I find the titles from the analytical writings, especially that for issues, are really good topics that can evoke our thinking in depth.

Thanks for your comments and they are always welcome

Following is the original article that i wrote:

Nowadays people are becoming so eager to succeed that they are becoming quicker to take action but rather than taking a good consideration before that. In fact, with a fast speed of working and higher efficiency of action sometimes do provide us greater production. However, such quick reactions can hardly always work.

An adequate thorough thinking for some actions that are to be taken is beneficial, especially for some important decisions. A common experience that can convince us is that we can make a decision in seconds, but we can never finish an intricate task in seconds. Putting a pre-determined decision into practice involves many steps that we can hardly reach wholly in a flash, and a thorough thinking brings us the new opportunity on such thinking. A good example for this is making a plan for a chemical experiment. It is the truth that an initial plan can be made in quite a quick action, while, more importantly, we should examine and reconsider the very steps during this procedure, on the medicine we use, the controlling group we set, and the equipment that we may ask for. Without such intense thinking on realms of this experiment, various problems can occur during the coming procedure, and, some fatal errors that we failed to realize prior to their occurrence can sometimes directly turn this experiment into failure.

And such thinking can take something that we miss at a first glance into consideration, such as the consequence of some actions that can bring us great influence. Suppose that a local government is thinking about a project of the establishment of an industry that can produce high pollution to the environment, but its establishment can boost the economic growth as well. Taking the viewpoint of short-seeing, a kind of thinking method that only covers the influence or that consequence of a specified event in a short period, the local government would pass the decision of the establishment on the consideration of the economic growth. But once the staffs take reconsideration on such plan in depth, more or less, he or she would think about the pollution matters. And a professional evaluation can then be taken, which involves professors and experts on environmental science, to suggest the magnitude of its pollution on local environment. Once the cost on environment is higher than the economical profit, we suggest it as the result of evaluation, this project would be denied rather than the acceptance.

But a fast reaction can make as being competitive to the other opponents, which is of great significance contemporarily. This frequently occurs in business world. An investing analyst working for an investing firm would require taking intermediate action when they find an investing opportunity rather than a time costly reconsideration; otherwise the opportunity would never be back. The other example exists in the industry of manufacturing, a competitive industry nowadays. The key determinants of the profitability of a firm are depending on whether they can turn a good design into productivity with adequate high efficiency. Only when being with high productivity that the firm can get the dominant role in industry and be profitable. Any delay on this procedure can be consequential.

In sum, taking good consideration before the action can help people be more aware of the possible difficulties and problems that they can probably meet, and such thinking also offers people an intense understanding on the steps that would involved in their actions. What’s more, such consideration can prevent people from making some errors taking quick action but missed the awful consequence it can induce. But admittedly, under some occasions, quick actions are required; a delay on action can lose the opportunity sometimes.

Update to Endnote X3: A Pleasant Experience

初识这个软件,是在2007年的初冬。当时我已经在现在的学校开始我的研究生学习二月有余,手头也下载了一堆论文,但是由于缺乏一个有效的管理方法,文章的归类整理耗费了大量的时间。更重要的是,由于没有一个统一的方式来整理所有文章的摘要,对已读文献的复习也造成了很多麻烦。事实上,我从来是不推崇通过写读书笔记的方式来读文章的,那样只能导致非常低的效率和不完整的知识结构。

通过科研论坛的交流,我知道了这个软件。但是由于当时中国知网并不支持Endnote格式的数据导出,科研论坛的工具板块就有了大量的讨论CNKI的帖子。尽管这个问题在我后来的使用时已经得到了官方的不完美解决(之所以说不完美,是因为CNKI的数据并不包括页码,这是不符合国际规范的),但这个软件却给我留下了印象。该软件可以非常方便的从ScienceDirect,Blackwell等数据库直接得到Citations,而且可以很方便的同全文链接,这就为我电脑里的文章提供了很好的归类和整理。

该软件更大的好处在于可以自动插入citation和生成Reference。这应该是这个软件更重要的功能了。他可以支持很多期刊的格式,并提供一些重要期刊的模板,为我们的写作提供很大的方便。由于比较早使用这个软件,我现在连期刊的Reference的具体格式要求都不清楚,尽管我会按照Author’s Guide的要求去做一些Style的调整,但是却不用花大量的时间。或许,这从另一方面也说明了这软件的便利吧。

这次更新的X3,给我最主要的改观有两点:一是启动速度大大提高;二是与Word 2007的冲突问题的解决。在我过去使用X2版本的时代,他缓慢的启动速度始终让我很抓狂,尤其是在通过Word工具栏中的Macro来启动的时候,它的速度之慢可以与鬼行的速度相媲美。同时,由于Word 2007大大提高了上下文的Spelling Check和Grammar Check,导致了Endnote的域代码与其产生较大的冲突。这种冲突通常会表现在一些Word的长文档中。但是X3现在近乎完美的解决了这个问题。

X3的另一个亮点则是可以自动侦测所在IP可用的数据库并自动下载文献全文。可惜我没有机会来测试这个功能。因为我所在的学校并不重视科研资料的建设和保证,我所在学校的IP几乎没有国际顶级数据库的access。但是据国内外的BBS反馈,这个功能与X2的Direct download相比,改进还是非常大的。

慢慢的,我开始习惯了Word+Mathtype+Endnote的工作方式,尽管我不满意Word的某些功能,但是由于我对Latex表格处理的畏惧,这种工作方式估计暂时不会有太大的变化吧。

Write a Blog Article with Microsoft Word

It has been for more than 3 years since my first contact with the blog, and the most frequent way for my updating is just the on-site editor. That is, I just write on web directly. But such way owes quite an important advantage that many advanced aligning skills cannot be used, such as some requirement on accurate positioning of pictures.

After the construction of this website, my good friend, Wung, told me to use Windows Live instead, a component of Windows Live Packs. It is quite a good tool that involves more instruments, but considering it to be a free tool, some functions are still not supported.

Thus it draws me to Microsoft® Word. Fortunately it is quite easy to use as well. But something follows should be prepared if you are willing to take it:

  • The XMLRPC function of your site should be enabled
  • Office Live Add-on is suggested to be enabled

Thus you are able to start to write an article with your Word, some steps are to be followed:

  • Use File – Publish – Blog
  • A dialogue box appears, following the instructions and filling your domain, username and password
  • Write the article, all the actions for writing are the same as writing a paper that we usually do
  • Click publish when finished

Now you may take an attempt if you are interested in writing with Word as I amJ

Stata 11 is Coming!

Stata官方说法,7月27日将发布Stata 11,而如今官网显示已经开始发送(shipping)。更新文档显示tag Stata 11还是值得期待的。不过可怜的是我们并买不到美国的学生版,而超过1000美金的售价恐怕非我们所能承受。这不能不说是我们的悲哀。好在会计学的期刊并不如理科杂志那样会要求提供所使用专业软件的授权资料。要不然,我们的成果恐怕只能自己欣赏了,呵呵

We are pleased to announce the release of Stata 11, which begins shipping on July 27!

Stata 11 is full of exciting new features, including a complete suite of tools for multiple imputation, support for factor (categorical) variables, competing-risks survival regression, a flexible GMM estimation routine, state-space modeling, multivariate GARCH, and predictive margins. The GUI has also undergone an extensive update, bringing you a new Do-file Editor, Data Editor, and Variables Manager. You can also now include Greek letters, mathematical symbols, and multiple fonts in graphs.
Every copy of Stata now comes with complete PDF documentation — of course, printed documentation is still available as well.

Windows 7, Some Word prior to a new era

由于最近的日全食诱发了我的牙疼,而我的牙疼直接诱发了我的懒觉(什么逻辑?我也不知道),结果由于睡眠过多,导致了头晕晕的,实在是干不了什么正事儿了,就上网看看CB,说实话,已经很久没有去了。以至于看到了Win 7的RTM于7月23日封装时,我这低速运转的大脑才反应过来咋回事儿。

回到远景论坛,发现Win 7的下载贴铺天盖地。实在是很佩服他们,同时也很怀疑。毕竟RTM才出,MSDN上也没有放出官方的ISO,他们的文件都是从哪来的呢?呵呵,先不管这个,更搞笑的是,网上还提供了大量的所谓OEM激活工具。但是看了一遍帖子发现,其实这是一个带时效的激活工具,同时截图显示,即使声称是OEM激活,其Product ID也并没有显示为OEM。看来真的要使用正式版的Win 7,恐怕尚需时日。

也来说说正版化问题。自从我第一次接触计算机的90年代中期开始,我就很少见到正版的东东。唯一见过的就是当时江民公司的KV300的3.5寸软盘。而当时我们所用的DOS,UCDOS,SPDOS,WPS这些鬼东西,居然都是可以用软盘直接拷回家用的。而在我当时启蒙老师那里看到的一些软件盗版,比如3DS,ACDSee,却都成为了国内后来红极一时的软件。但是当时个人计算的普及并不广,所以盗版范围也有限。我仍然记得当时的盗版光碟售价高达几十元人民币,呵呵

Win 98的时代开始,电脑的售价开始到了1万以下,盗版软件也开始变得疯狂起来,盗版碟价格也开始变成了5块钱的标准价。其实想想当时98的盗版真的不难,Win 98的安装只需要一个单独序列号验证,既没有网上验证,也没有激活这一说。而当时Win 98的中文版售价高达1998元人民币,还真不是开玩笑的,就算是现在的价格,都接近Windows Vista Business了,而要知道,Win98只是一个特别喜欢蓝屏,动不动就非法操作的“瘟到死”而已。不过,这个“瘟到死”系统以及他的兄弟“瘟我”(Windows Me)的寿命还挺长,以致笔者在该系统发布10年以后还能见到它的身影。

Windows 2000开始,微软放弃了9x的核心,转而开始了基于NT核心的研发。而这一调整也大大改变了Windows系统的稳定性。Win 2000由于是基于早期的服务器系统NT 5的开发,在个人应用方面稍差,但是稳定性甚至强于XP(不包括XP SP2),所以到目前为止,几乎国内所有的计算机考试,包括托福,GRE这些都是基于Win 2000的系统。而Win 2000的简约的风格却也给我留下了不可磨灭的印象。但是Win 2000的零售版价格我还真不清楚,估计不会便宜。

Windows XP,目前号称是微软做的最好的系统,也是在国内个人电脑上流畅最广,对新生一代计算机用户影响最大的系统。而对早期用户而言,新加入的网络激活模式折磨了一大批人,当时很多人,包括我的很多朋友,不得不在30天期限到来之日重装系统。而XP的默认主题在当时看来是无比漂亮的,而XP SP2则是由于微软迫于当时蠕虫的泛滥而做了一个史上最牛补丁,几乎把XP改了一遍,以至于我们当时在宿舍搞定了SP2的时候都在商量着如何使用。而这个系统的正版率相比较前面的系统,尤其是近两年来有了很大提高,这得益于笔记本的普及,毕竟很多中高档的电脑都会预装OEM系统。

Windows Vista, 一个国外普及率还不错,国内骂声一片的系统。平心而论,Win XP在现在的高端机上已经力不从心,尤其对多核处理器,高容量内存的管理。Vista其实很好的弥补了这一点。就我的笔记本而言,在我某日自己动手把内存换成了2G以后,不知道为什么,Vista的运行速度反而要高于XP,这点我百思不得其解,或许这也是Vista的管理上的优点吧。事实上,Vista的早期版本并不稳定,而SP1则很好改善了这一点。现在的SP1版本应付日常工作,甚至于一些科学软件的运行都没有问题了。真是想不清楚为什么大多数人抱着XP不放。更重要的一点是,在家庭版本的定价上,Vista在大陆的定价是历来系统最低的,或许这也是微软在中国正版化策略的一个开始吧,呵呵。

Windows 7,我老了,没有当小白鼠的冲动了,不过看评论,应该是个不错的系统,让我们翘首以待吧。

最后上几张图,让跟我一样的非新鸟来重温旧梦,高唱Yesterday Once More 吧,考虑到我博客的读者都很年轻,就不搬出DOS时代的古董了。。。

这是最早进入中国的Windows系统,呵呵,也是我用过的最早的~~,需要DOS支持,还记得命令么?Win /386:哈哈,386增强模式

这是第一代的Win 95,可以独立启动,但是不带浏览器。

这是号称Win97的,更为大家熟悉的版本,当时很多企业用它

Win 98,不用多说,非常著名的系统

 

看到这个封面,想到了我大一大二的时代,呵呵,那时候宿舍一哥们的电脑就是这个系统

 

Win 98的美化版,一大好处是插入USB设备不再需要安装驱动

XP,不过这是早期的,不信?你看看你自己电脑上的XP左下角是两行字还是一行字?呵呵

Solar Ecplise: Staying Behind the Clouds

今天是难得一见的全球性日全食,然而天公也真是作美,这么多天不下雨,今天居然破天荒的下了场大雨。不过也好,本来还在考虑是否去桂花公园,我家附近的一个公共观测点,现在彻底打消了这个想法了。老老实实在家看CCTV直播了。

相比较我而言,武汉的哥们姐们相对运气好很多,他们应该可以看到完整的日全食了,呵呵,不过按照CCTV的直播来看,浙江那边的观测显然是最好的,不过现在网上还没有高质量的图片上传,只有一些很一般的照片。估计下午应该会有了吧。

至于所谓的500年一遇,那真是有误人子弟的嫌疑。在网上的检索发现,其原文是说,在未来300年内恐怕不会有类似于今天这样的全球性日全食,而不是说未来300年没有日全食。事实上,去年我国西部地区就可观测到日全食。

A Travel in Suzhou

Due to the preparation for my GRE exams and some works for paper, I have been stayed at home for more than two weeks since my return from SNAI for the training. And in fact, the time can be longer if my friend, Jiang and his wife don’t come.

They come to Suzhou, as their first-time visit, in quite a hot morning.  And I met them in a KFC restaurant near the railway station. Now a trip starts.

We firstly paid a visit to the famous sight: Tigher Hill, with a tower that is regarded as the symbol of Suzhou. It is really quite a hot day, very few tourists appear there, but the price of the ticket, is still as high as the temperature, asks for 60 RMB. Thanks to my annual card, I do save a big deal on this visit.

1

This is the gate for the park, just see how the sun shines! But undoubtedly, it is beautiful.

Following is a stone that are divided sharply, as a legend says, it was done by a sword of King Wu.

2

See that tower? Yeah, it is the symbol of the Suzhou City, no less important the Learing Tower of Pisa in Italy.

3

The nex station we refer to is the Gally in Xu’men, where held the World Heritage Meeting. The weather that day is really good, just see the blue sky:)

5

Following is a remote sight of Xu’men that I shot standing at the top of the bridge.

6

The last photo is just the Xu’men. Still remember the old days when I lived near that place. It was as brumal as you can image! But now it is really a beautiful place.
