English is not easy to master. Pronunciation is one of the difficulties. Words are written in a totally different way from what they are pronounced. There are patterns, of course. It just takes some time before you notice the pattern. Below is a pattern of pronunciation: Cancel, Novel, Pencil...

Windows Update and Its Discontents

A few things why I never trust Windows to update itself. My PC has frozen several times because of the Windows Update....


  1. After updating, you may get errors that some applications and software no longer work or work incorrectly. 
  2. It consumes huge amount of CPU and Ram while updating, secretly. So when I type a document, browse the internet and/or watch a video, it freezes. 
  3. If you use some cracked software, the update would remove it and make it a trial ( that is for MS products only I guess). 

At least those are my experiences, and I choose to disable its automatic update and check it once in a while. If I need to update any software, I go to that software directly.

A Simple LaTeX Editor Comparison


To begin with, I am not an expert in LaTeX. I have just begun using it to write some books. And here, I am not writing about what is Latex or how to use it. I assume you have some knowledge of it already and maybe trekking to find a good editor that may ease your work in LaTex.

I have just finished one book with tears. Currently I am writing several other books. And a good LaTex editor helps you in a great deal. Here, I just want to share my experience after using 3 editors: TexWork, TexMaker and TexStudio. 


 TexWork
This one came automatically when I installed MikTex. It is the basic form of latex editor. Thus, It does not help you much. 
  • Very least Shortcuts are provided. You may have only Italic and Bold Shortcut, to sum up. 
  • Very least Autocompletion: you have to type \begin{document} blabla on your own. 
  • It is difficult to compile files as well.
TexMaker
It is after I got many errors and I feel it takes me much time to write something like \begin \end etc. I think there must be some better editors. So I tried TexMaker. It helped a lot!!! 
  • Shortcuts are abundant:  Ctr+Shift+M which replaces $$ and many more. 
  • Autocompletions are great: when you type \beg, it would offer the candidates like \begin{.} and then you type in the {} , say do, it will completes \begin{document} with \end{document} for you at the end. 
  • Compile and Build etc works like charm.
TexStudio
This one has all the TexMaker has to offer except that it offers in a more convenient way such as more toolbars and shortcuts.

Hope it is of useful to you, and save you some times and efforts.

How to Include Japanese and Khmer Text in Your Latex Document

I have been finding a working example to include Japanese in my Khmer document. So I share this article in a hope that it is of useful to you.

 \documentclass{article}
 \usepackage{xeCJK}
\setCJKmainfont{Meiryo} % Here, check out your Font in your Windows and type the name of any Japanese font you like. You don't need to add the extension such as .ttf .

And in my case where I use Khmer as a main text, I set
\setmainfont{Khmer Kampot}
\usepackage[utf8]{inputenc}

So I begin:
\documentclass{article}
 \usepackage{xeCJK}
\setCJKmainfont{Meiryo}
 \setmainfont{Khmer Kampot}

\usepackage[utf8]{inputenc}

 
 \begin{document}
 សួស្តីកញ្ញាៗ
 
\section{練習は楽しい}
日本語が分からなくても日本語を話せる。 
\vspace{0.5cm}
 
Of course, English, the language of \LaTeX  producer, is there. 
 
\end{document}
 
With Xelatex as the compiler, it becomes: 
Example of Japanese and Khmer in Tex Document


 Note: I use TexMaker as my Latex editor. Previously, I used TexWork and it sucks. And I use TexLive, switching from MikTek, which contains limited packages.

My Summary of Fukuyama's Political Order and Political Decay

The first book I read that contains so long list of reference is Basic Economics of Thomas Sowell. When I read this book, I was surprised that it ended at 70% of its Kindle version. Another 30% is the long list of reference.

Clearly, the author is a well-read political scientist. He combines very relevant sources of knowledge to his topic. After reading this book, as not a student of political science, I feel my knowledge is doubled, perhaps due my scant knowledge in the subject. When I read Henry Kissinger's On China, the word Order was used widely. I could not even decipher its meaning!!! However, Francis put in plainly, and the use of its opposite political decay helps me to understand deeper.

This book targets those who are interested in developing a country. To build a country, one good leader is far from sufficient. A learned reader would not deny that one needs a good system or institution to run a company, an NGO, an institution or any organization that involves human society. Specifically, how to develop a sustainable institution or institutions i.e. political order and what kinds of elements may those institutions collapse i.e. political decay? There are three core elements for a political order: State, the Rule of Law and Accountability. The consistent balance between the three pillars make a sustainable political order.

State

There are many possible reasons as to why and how a State was formed. For instance, the need for a strong army, with an efficient ability to collect tax, to defend one's own country from foreign invasion is one of the main reasons, and it happened to countries such as Prussia, early Qing  Dynasty etc. The State holds monopoly power and is able to enforce laws or customs in their controlled territories on all residents.

Rule of Law

All early dynasties, at their most clean form, ruled by law. All people are under the law except the monarch. This is efficient in controlling the subordinate but fail to create a political order because people, in their genes, think people are equal, at least at the back of their head.

The rule of law is also indispensable for economic development. Without clearly defined and enforced property rights, no one has incentives to make the best use of their property as well as to develop it further, as a result the economy stagnates.

The State itself has to be under the law as well. No one is above the law. In addition, the law has to be impersonal,i.e. not created in favor of this or that group even to the poor.

Is the decision making has to be rule-based or discretionary? This is an old question. The author posits that Denmark has the most efficient in terms of the rule of law and discretionary decision makings. The U.S government has many principals (to use economic concept of principal-agent problem) and contradictory rules. 

Accountability

I believe the author is a free marketeer. However, he is not a libertarian thinker. I believe he is one of the few political scientists who understands economics very well and reject some of its theories very well as well. For instance, the concept of fairness. Redistribution of wealth, he acknowledges, creates disincentives and distorts economic activities. However, people have different view regarding fairness. When people see a bunch of their neighbors are extremely rich beyond their imagination, they may feel it unfair and ask for or vote for redistribution. If the demand for redistribution is high, like in Europe, the political order is less stable when people choose politicians who redistribute instead of smart and responsible ones. People need a government because they have reasons to expect from government and/or politicians, where sometimes they cannot differentiate. Thus, clientelism and patronage, if not tamed, will play irritating parts in politics.  

I hope this summary induces you to read the book, not to stop here!!!

    A Review on The Commanding Height

    As its title suggests, in this book the authors attempt to contemplate on who should control your life, who should run the economy, or how laws should be based on. This is the never-ending debate on big government versus small government, Keynesianism versus Classical Economics, liberal democracy versus communism, dictatorship, monarchy you name it. For those who are curious how popular economics can change life, this book is best.

    The time frame this book deals with is mainly during the Cold War, the confrontation between communism of Soviet Union and China and Western democracy. Key players include Margaret Thatcher of UK, Ronald Reagan of the United States, Gorbachev of the Soviet Union, Deng Xiao Ping of China and some leaders of developing countries trying to lift their country out of poverty. Nonetheless, what is more interesting is ideas behind those leaders. Those ideas are from mainly economists including Milton Friedman and F.A. Hayek, the latter’s name is quite uncommon to even economists. 

    Keynes lost the battle to Friedman and Hayek during the 1980s till 1990s at least in the United States and the UK. It was manifested that government cannot control the economy. The Fed could not and should not use its monetary tool to offset recession or create a free boom for the economy. Regulations hurt the economy. 

    The battle is not over. Reagan’s tax cut, for instance, is seen, for instance by a Nobel laureate in economics Joseph E. Stiglitz (Globalization and Its Discontent, and the Price of Inequality), as widening wealth gap between the rich and poor and hurt the economy. Recently, since Bush administration up until now, Keynesianism is prevalent in the Fed. 

    This book is so famous and influential that the U.S public media PBS made it into TV Show. I hope after reading and watching it, you will recommend it as a must-read book and/or must-watch show.

    A Note on From Dictatorship to Democracy

    In Why Nations Fail or related topics especially those of economic development or political science, we cannot see how to develop a country suppose you were a victim in a failed country. At least you are not the leader of a country [you would not read this piece of writing if you were!]. This book attempts to give guidelines, at least hope, for the victims, the suppressed, of dictatorship to topple dictatorship to set up a lasting democracy. Those who aspire to install democracy in their own country are the targeted audience of this book. Those who want to be a citizen of a country instead of a slave for other men are encouraged to read this book. 

    Personally, this book gives me hopes, a hope that democracy can be set up in any country and there is a way you can switch from dictatorship to democracy. 

    I read the 4th US edition, kindle version. Below are its sections:

    1. Facing Dictatorships Realistically
    In Cambodia, for instance, people around me always hope for the interventions of US, UN or EU to lift their country out of poverty and dictatorship. People need to know that they need democracy. Thus, it has to come from within. This is not to say that US interventions, for instance, are useless but it has to begin with that end it mine: teach them to democratize. 

    Violence does not end dictatorship. It removes one for another to come. 

    2. The Dangers of Negotiations
    Negotiations can be used under certain situations. That is possible when there is a strong democratic opposition. In addition, political defiance is necessary. 

    3. Whence Comes the Power?
    Where does political power, or any kind of power, come from? Why people do what other people tell them to do? The answer to these questions also tell what weaknesses dictatorships have. 
    4. Dictatorships Have Weaknesses

    5. Exercising Power
    Where should one start? Where is democratic opposition strongest? Military struggle? Of course not. That is where dictatorship is strongest. Tautology one may say. Political defiance is the answer. 

    6. The Need for Strategic Planning
    One may see the spontaneity of popular uprisings against dictatorship in many countries such as in Arab Spring. Dictatorship does not last as it can't have another good dictator to continue its unpopular regime. Democracy would not last as well if democrats do not plan for its full installation. The latter sections deal with the need to plan, how to plan, how to apply the political appliance to disintegrate the dictatorship and lastly how to make democracy last. 
    7. Planning Strategy
    8. Applying Political Defiance
    9. Disintegrating the Dictatorship
    10. Groundwork for Durable Democracy

    Cambodia's Curse, a Review

    The author is no doubt correct to point out that, among many factors, the lack of the rule of law and uneducated Cambodians and their politicians are the curses to Cambodia’s development. 

    Are Cambodians resistant to change? 

    There are plethora of research and authors, including expert on Cambodia David Chandler, who opine that Cambodians resist change and want to be left alone. Although Joel Brinkley cites the General Election in 1993 when people chose to change despite threat, intimidation and lie, he agrees that Cambodians are docile. As simple as the theory of expectation says, people choose to change only when they think it is the change for a better future. They believed King Sihanouk would bring a better future for Cambodia that is why they dare choose to change in 1993. Currently, there is no figure who Cambodians can compare to King Sihanouk. Therefore, the battle to win trust from the people is being fought by the ruling party and the opposition party with no decisive force. The author goes too far to say that Cambodians are not ready or courageous to fight for change as can be seen in Myanmar, Sudan etc. He even raises the military standstill in Sudan as a better model. He forgets to mention the uprising against the election result in 1998, among other courageous activists and local NGOs in Cambodia. 

    Hope?

    Although the author mentions various curses in Cambodia, he also foresees a fast changing future. This seems to contradict with his arguments anyway. The changing demography and technology are moving Cambodia to a better country, forcing Cambodian leaders and politicians to be more accountable in what they say and do as well as keeping Cambodians themselves up to date and more educated. 

    Defects in the Book

    In the bibliography, you can see only around a dozen of books. Of course no one reads all books in the bibliography, thus one should expect less than that as the author admits to have read some of them on the plane. One should see factual errors, as Sophal Ear has pointed out. 

    Is Cambodia on the right direction? The author quotes the two surveys, one by IRI and another by the Asia Foundation, without any second thought. The survey by Asia Foundation, for instance, has two main weak points. First, the sample is only 1,000. This sample is sufficient if they interview people in Phnom Penh to understand their view, but it is too small for a countrywide opinion poll. Second, the questions are vague (I am not sure about its translation into Khmer, as I could not find it).  I am curious how uneducated Cambodians perceive this question On the Right Tract… Whatever the result (results of 2003 and 2014 surveys are opposite), one must use it with care. 

    Rather than analyzing a race, Cambodians, I believe one should do so treating them as a group of people to reduce biasness. Americans would not love freedom and democracy without institutions set up by the UK. The ideas of John Locke did not come up by dreams but by studies. There are various factors that may change a country (See Why Nations Fail, for instance). Although the author tries to explain factors that make Cambodians lazy, for example, I believe he should try harder to look at it from economic and political science perspectives instead of racial perspective as some French did before and during the Colonial periods.

    The Worldly Philosophers

    A graduate student who could write such a good book is an exceptionally brilliant person. His novel style of writing manifested in this book keeps readers curious and allows readers to be back in the time of those economic thinkers. 

    Although the author well summarizes main ideas of those philosophers, he frequently focuses less on their defects and weight them against their main theory. Any thinkers have their philosophical opponents, at least in their time. This book is not about which school of thought is right or describes economy more correctly, but about the ideas of those worldly philosophers. 

    Although it is a good book, it is not very good. I do not rate it 5 over 5 because, firstly, when one can summarize opposing ideas, one should be able to see which is more reasonable. Secondly, I expect more rigorous study on an idea and its opposing view. For instance: 

    Adam Smith

    It is very safe to admire Adam Smith in economics. He is known as the father of economics by many. However, I really doubt people actually read him. It is a sad thing that the author of this book who also wrote Essential Adam Smith missed contradictory points in his books. We tend to think that those free market ideas such as laissez faire, free trade, wealth vs gold were originated from Adam Smith. 

    I read Adam Smith’s The Wealth of Nations, the abridged edition with summary inside for each section, a few times and found many contradictory points in principle in this same book. For example, the government role in the economy should be big instead of three main ones: promoting rule of law, national defense and high cost public investment. Here I am not discussing in details. I suggest another book An Austrian Perspective on Economic History which deals with this issue comprehensively. 

    Alfred Marshall

    Standing on the shoulder of marginal economists, Marshall could develop the demand and supply curve as we know it today. This is the beginning of modern mathematical economics. In this book, credit was given to Marshall but least to previous marginal economists. In addition, I also feel how powerful this idea is to solve Adam Smith’s Diamond Paradox is not even touched. Those who are curious why P-curve is vertical, not horizontal, are advised to dig into this part.

    Joseph Schumpeter 

    Schumpeter opined that capitalism would not work. Growth in capitalism is promoted by entrepreneurship of capitalists. Capitalists invest to increase profits. In the long run, they would run out of ideas on what to invest or the profits become zero by competition from other capitalists. This idea of creative destruction is today denied. The author this time takes side.

    John Maynard Keynes

    Keynes biography, accomplishments and theory are very well summarized. However, his main philosophical opponents Milton Friedman and F.A Hayek are not included. Hayek and his book The Road to Serfdom, however, was used as a wake-up call on Keynes theory that might lead to nothing but socialism. Keynes acknowledged that possibility but put more trust (or hope) on government officials. 

    Final Say

    As its full title suggests, this book is about the lives, times and ideas of those economic thinkers. Those who are puzzling on which school of thought is better, for instance Classical versus Keynesianism, or those who try to find the connection between long run and short run economy may not find the answer here. (I suggest The Clash of the Century). In conclusion, however, this is a good book for its title.

    Afterlove

    I did not like a novel in the past. I felt it would increase no knowledge, or concrete knowledge. A Khmer senior in my university recommended this novel to me and at the same time gave me this book. That is how I got to read this book and it changed my view on novels in general.

    The story begins with a family of happiness, a solid marriage, caring husband and wife with two children and satisfying careers. Then all of a sudden, a tragedy left the wife all alone. They are all dead except the wife. One can imagine how afloat she becomes, attempting even to commit suicide.

    Then she resorts to superstition. She wants to meet them the last time. It happens that she might be able to do so. In the process, her life is changed. That is the interesting part.

    The story is full of sadness and romance but no comedy. You don’t expect jokes in romance, do you?

    Conundrums
    Do you believe in reincarnation? What would happen to a person after he/she dies? These kinds of questions never end with answers but more questions. The author deals with this issue in his very neutral way. He would say yes and no at the same time. But what more important are what you believe and choose to do in your life, instead of finding out the true answer to those questions.
