Principle of Time of Flight 3D Camera

A near-infrared light (NIR), via light-emitting diodes (LED), is emitted by the system

and then reflected back to the sensor. Many authors [9]–[12] provide formulations for sinusoidal signals, although other periodic functions can be used. Every pixel on the sensor samples the amount of light reflected by the scene four times at equal intervals for every period, (m0,m1,m2 and m3 in Fig. 1), which allows for the parallel measurement of its phase

Conservatism vs Liberalism

There are some good arguments in this youtube but they all miss their points.

The lecturer repeated say that being in that University is a privilege.
For ordinary listener, you do not realise the implication of what he is saying.

It is not easy to go to that university. It means that, even though you have money, you may still not be able to get into that university. Which is not the whole truth. You may not have money to pay tuition fees.

What listeners do not realise is that money is not taken into account  by that lecturer. He assumes that only academically deserving students are allowed in that university.

Why would they argue about placement? It is about affirmative action policies in USA, where places in a university is reserved to minorities or races that had been subjected to discrimination.

The lecturer argued that affirmative action is completely wrong because a deserving student will lose places to a less qualified student and correcting racial discrimination in the past is completely wrong. Which is exaggerated. Just becasue you cannot catch all criminals, does not mean that we should abolish all criminal laws.

In ethical considerations, facts must be observed and exaggerations avoided.

Affirmative action policies can still be implemented despite discriminatory practises just like income tax policies, in order to maximise the resources of the nation and increasing the livelihood of its citizens.

One simple way is to stick to academic results, instead of ability to pay. In that way, the standard of education does not drop. So scholarship money should be given to people who really cannot afford it, and it should be paid back or bonded with work obligations.

Giving monetary rewards to best achievers has some good but it should not be overdone.

There are other issues that should be addressed. What is important is to stick to facts.

There are other videos spread by these conservative groups that are the backbone of President Donald Trump. If we have time, we should try to listen to them and understand their viewpoints.

Response to Facebook's Ridiculous Censorship

You have given a very dangerous precedence.

Paranoid responses are allowed but explanations of the actual meanings of the phrases are not allowed.

How could you allow people to insult national languages and the name of a country, and when people responded, you complained that it is racist.

It is like the Jews in Israel killing innocent Arabs, and when we commented that the Jews in Israel killed Palestinians, it is condemned as racist, because it incites hatre. Bloody idiot. You are hiding the truth in order to hide hideous racist crimes.

Racism should be tackled with truth, not paranoid. We cannot just disallow any condemnations of a person of a certain race, and consider it as racism, and therefore allow worse responses such killing them for complaining against a member of the race.

My post that had been deleted is such a clear example. A Malay guy was insulted by a racist chinese salesgirl who insulted his language and country, that happens to be the language of the country that the girl is staying and supposed to be loyal.

To add salt to injury, she offered alcohol to everyone at a public place, without any approved license. You do not serve alcohol at a supermarket. Only display canned or bottled drinks.

In response to that insults he asked if the girl is chinese.
Is that racist, if we are to ask for someone's race? Yes, to racist bastards like chinese and jews.

Because the chinese in Malaysia believed that they were insulted by being called racists, they justify a really racist actions of terminating his employment and threatening his children that study in a chinese school. Actions are what constitue racism. Not insults against individuals.

Facebook may have a duty to protect harmony but do you want to protect harmony of child rapists, murderers and racists? Why should we care if we insult them and their actions? In fact, it is our duty to insult these bastards so that they realise the consequences of their actions.

Stopping an article because it hurts the feelings of others is also stupid. Because many people feel insulted if they are proven wrong. So, should we stop all posts that try to explain all the wrongs in the world? This is what FAcebook is doing right now through its idiotic reviewers.

When a Malay wants to insult people, he will use the word "babi" or :"pork" but why should the pork eaters feel insulted. It is just like people calling others as beef eaters, or shark eaters etc. Are you insulted if you are called with such names? You will be an idiot if you are.

Worse, there are ulteriour motives behind being insulted, which I detected as extreme racism, i.e. getting excuses for the blatant racism that the chinese in Malaysia exhibits.

As to "cina keturunan babi" insulting to the chinese race, this is completely false. The Malays will use the same insult to any person of any race, because the Malays consider "babi" as dirty.

In Malay, the phrase "cina", translated as chinese, does not refer to a race but a person. It is just the way the Malay grammar is interpreted. Malays like to use this kind of insult when directing to a person, even to its own race, Melayu bangsat (Malay bastard) does not mean that the entire Malay race is bastard. The race is put as an idicator that he is a traitor for his race by being a bastard.

If you start interpreting pig, or "babi" as an racist insult, then you should start disallowing others animals as well, such as crocodile, shark, etc. It is just ridiculous how people can be so sensitive.

We cannot allow guilty people get away with murder just because people express their displeasure towards them in a truthful way.

You may read more about my analysis of the possibly insulting phrase at:
https://othmanahmad.blogspot.com/2018/12/is-cina-keturunan-babi-racist-and.html

Is “cina keturunan babi” racist and incite hatred?

To some people yes.

But to these people, to be called “cina” or “chinese” is already racist and insulting.

Our official policy now is to consider it as insulting, but it is only applied in West Malaysia.

In Sabah, where I live most of the time, this is not the case. We identify them with their races and sub divisions. Again, this is only true in the Eastern part of Sabah. In the West Coast, the Kadazans, part of the Dusun tribes have a strong movement in creating a strong ethnic group KadazanDusun.

A lot of Malaysians consider Sabah as a model of racial tolerance. My theory is due to our pride in our individual identities. This is again not true for Filipinoes in the West Coast or those in West Malaysia. They felt insulted when asked about their race, and I suspect they lied about their true races.

My belief is that for true racial harmany, we just need to be honest. Lying will only complicate matters and leads to racism. Categorising races in Malaysia as Malay, Chinese, Indians, Natives will only lead to frictions among the races. These major divisions are created to enhance unity in each of these divisions so they lie about their races in order to gain legal advantages.

That is why even facebook allows people to consider calling anyone chinese as insulting and racist. I think similarly for Jews. It is not surprising when you consider that the founder Mark is a Jew and his wife Chinese.

This is ridiculous. It is not according to facts and logic. It will be disastrous sooner or later.

What actually is racism?

Prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one's own race is superior.

‘a programme to combat racism’

https://en.oxforddictionaries.com/definition/racism

So any antagonysm is considered racist, even the truth. so catching a thief of a different race is called racism? Certainly not correct but widely used. Especially by chinese and jews, and this facebook reviewer.

https://en.m.wikipedia.org/wiki/Racism is better.

Racism is the belief in the superiority of one race over another, which often results in discrimination and prejudice towards people based on their race or ethnicity. 

Racism cannot be used against one individual of a race.

In Malay, the word “cina” alone refers to an individual or a country. To refer to a race, we must attach the adjective “bangsa”, or “race”.

“keturunan babi” means “descendents of pig”. It is a deregatory word used by Muslim Malays against anyone who eat pork. It can be applied to all other races, including, non Muslim Malays.

Is it deragotary, but not racist. It is applied to many races. Ok, you may call it anti-religion but it does not apply to vegetarians. It is just the view of one religion over the others. I am sure vegetarians do not look kindly to all the carnivorous humans.

From the perspective of the chinese or pork lovers, can it ever be deregatory?

For example, I love eating fish, even sharks. Do I feel threatened when labelled as shark-eaters?
The speaker may think it is deregatory, but for me, it is an honour. Sharks may be our enemies, but its strength and speed in water is something to be admired.

So why should the chinese feel insulted when called "descendents of pigs"? They love eating pork, so they must be proud of pigs. If the chinese feel insulted, it is just they are too senstive and look for excuses to feel insulted. Just like being insulted when called chinese.

Going back to the word "cina" that looks like it is referrng to a race. I have explained that it is directed to a person. 

https://www.roketkini.com/2015/08/17/wahai-najib-bangsa-melayu-bukan-bangsa-bangsat/
Malays like to insult other Malays with the word "Melayu Bangsat".

It does not mean that entire race is bangsat (very bad, unprincipled). Only that he is a traitor to the Malay race.
So when we say, Cina Bangsat, it means the chinese who betrayed the chinese race by being bangsat, not the whole race.

Similarly for the Cina Keturunan Babi. He refers to her as a chinese who betrayed her race as descendents of pigs. That means he acknowledges that some chinese are not. He must have thought that pig genes are not infused to some chinese so are more acceptable.

This misunderstanding is due to poor command of Malay. The Chinese do not mix with Malays, and only learn Malay in schools. In schools they are not taught how to insult others.

How about Melayu Mudah Lupa, a book, written by our Prime Minister, Dr. Mahathir Mohammad?

It is only a book title so grammar is not strict. The meaning defaults to a singular person. A Malay tends to forget easily. Or An Englishman Tends to Forget easily. It is never meant to condemn the entire race, although Dr. Mahathir's intention is to refer to the entire race, including himself. True to Dr. Mahathir's style, he does not use the correct grammatical form Orang Melayu Mudah Lupa, if he wants to refer to the entire race.

Does the author of the phrase "cina keturunan babi" intends to insult the entire race?
Maybe, but the grammar and usage of the words does not support it.
He probably exploited the chinese ignorance of the Malay phrase to maximise the insult on her.

And yet, the hypocritical chinese insults the Malays using the same phrases to the PM, Sultans of Malaysian States and the Bugis Race, as descendents of Pirates.

Similarly for the Jews. The Jews are the ones who complained of being subjected to racism and yet disallow Arab residents from returning to their homes or get citizenship, but allowing Jewish immigrants automatic citizenship, which is clearly racism, in all definitiions.

Stupid illogical and devoid of facts pro-poor policy by a Professor in Economics

 I did not realise how dangerous this article is until I read the pro-poor policy. It has never been sanctioned anywhere in the world, but was championed by racist bastards in DAP for many decades already. His statements are devoid of any fact at all.

 

Just because you are poor does not mean that you deserve government aid above those who are more capable of contributing more. This is standard practise as shown by awarding scholarships to deservings students, and even giving money to people regardless of poverty in UBI, Universal Basic Income, which is the main theory to prevent disasters as a result of automation.

 http://unpan1.un.org/intradoc/groups/public/documents/un/unpan005788.pdf

 

Pro-poor policies had been identified as failures especially in commuist countries that later turned into socialists. DAP turned to socialism when the chinese supported mainland China with its communist policies.

 

 “It will also lead to a more confident, cohesive and resilient multi-ethnic society without the country being labelled as one of the very few where affirmative policies are needed for the majority rather the minority group as seen elsewhere,” he added.

 

The above is also a very dangerous statement made by racists, and had no bearing to the meaning of affirmative action AT ALL.

 

For example, the minority chinese and indians in USA are never candidates of affirmative action. It is just ridiculous to apply affirmative action on a minority.

 

Affirmative action is only applied to disprivileged people, regardless of whether they are majority of minority. The disprivileged is due to past racist practises that are hard to control legally. In USA, it was the whites who are racists, but they happen to be the majority. In Malaysian, it is the chinese, despite being the minory, had managed to control the economy. 

 

It is ridiculous and racist to assume that the minory chinese are successful because they are intelligent and hard working, whereas the natives are not. It is their racism that contribute to a large extent to their successes at the expense of the natives.

 

Just look at the multinationals and the Malays in Singapore.

Any racism is a waste of natural resources. If the chinese were not racists, the natives could have contributed to greater utilisation of Malaysian resources, for the good of all Malaysians.

Pro-poor policies, if implemented fairly, will make it worse for the chinese, who by defintion are not really poor, compared to the majority of the natives. I said implemented unfarily because the urban people are given more emphasis, compared to the rural natives. The rural natives do not even have proper hospitals, schools and roads. 

 

By providing the roads, schools, and hospitals in the rural areas for the poor, there should be no money left for the urban poor, that already have good roads, schools and hospitals by being in the proximity of all these facilities.

As to evidences of racism, it is as clear as daylight, and yet, Malaysia still has not implemented any anti-discrimiantion regulations, unlike USA. Many capable Malays are denied places in Chinese companies, given various excuses that are not even valid. For example, ability to speak Mandarin. Many Malays were denied employment despite being able to speak Mandarin. As for Malays, why should they work for these racist companies which form the majority of the companies in Malaysia?

We identify the racist by the stupid, illogical and untrue statement that affirmative action is not for the majority. Nonsense. Affirmative action is to stop racism.

   Originally, the idea of Affirmative Action is to help people under a systematic disadvantage, like kids from a former Slave Parents/Grand Parents.

   But as time progressed, it became a tool for "Racial Rebalance" of a organization (like a Soft Quota).

   So Hispanic is part of Affirmative Action Bonus, not because of the "Systematic Disadvantage" standpoint, but for "Racial Rebalance" Stand point.

   It is kinda Ironic, Since Asian actually had a systematic Disadvantage against them (Asian Exclusive Act that lasted till the 1940s, and Japanese Concentration Camp of the 1940s), but today they are being punished under Affirmative Action.. It clearly spells out the fact, that people (schools, companies) care more about their Image (Racial Rebalancing) than actual historic remedy.

   
   

 

Focus on reducing income disparity

The Pakatan Harapan government should focus on reducing income disparity between the rich and poor, regardless of race, in its pursuit to eradicate poverty, said economists. NSTP picture by ASYRAF HAMZAH.

By AYISY YUSOF - October 29, 2018 @ 12:14pm

KUALA LUMPUR: The Pakatan Harapan government should focus on reducing income disparity between the rich and poor, regardless of race, in its pursuit to eradicate poverty, said economists.

The New Economic Policy (NEP 2.0) must be amended based on the gains of the old NEP that has substantially closed the gap between the majority and minority ethnic groups.

Sunway University Business School economics professor Dr Yeah Kim Leng suggested that a pro-poor or inclusive NEP should be emphasised to strengthen Malaysia’s socio-economic foundations.

“This could help to shape more sustainable and resilient economic policies for Malaysia to attain high income status by 2024, as envisioned in the mid-term review of the 11th Malaysia Plan,” he told NST Business recently.

Yeah said the government’s intervention programmes like education, employment and business quotas and fiscal as well as financial incentives would raise the income of the bottom 20 per cent (B40) group.

“The attention on growth with equity should still be the primary policy focus. Without growth, restructuring of the economy and raising the living standards will be much harder and less sustainable,” he added.

Yeah said greater transparency and accountability will be important for the people to eliminate the identification of race with government policies.

He noted that steady economy growth over the years has strengthened labour demand which in turn has increased the ethnic diversity of employees in most organisations across sectors and industries.

“An inclusive and pro-poor NEP will foster national integration and equitable income distribution between and within each ethnic group.

“It will also lead to a more confident, cohesive and resilient multi-ethnic society without the country being labelled as one of the very few where affirmative policies are needed for the majority rather the minority group as seen elsewhere,” he added.

Malaysian Institute of Economic Research (MIER) executive director Professor Dr Zakariah Abdul Rashid, meanwhile, said socio-economic development in the current context of Malaysia was all about growth with equity as outlined by Prime Minister Tun Dr Mahathir Mohamad.

“Now everything lies on the implementation of good strategies. Bumiputera should also get its equal share of the prosperity of economic growth and development of the country,” he said.

Zakariah said the country’s largest Bumiputra population cannot be left behind economically for sustainable and stable economic growth of Malaysia.

“While subscribing to the principle of a free market, the strategy should be equally friendly to the major racial groups which have significant political and economic presence,” he said.

Bank Islam Malaysia Bhd chief economist Dr Mohd Afzanizam Abdul Rashid said the NEP 2.0 seems to be a delicate balance between promoting an equitable economic growth and instilling financial discipline.

“The government is committed to reducing the level of its debt and plugging any loop holes in spending,” he said.

“In this regard, the development of Waqf asset such as land and cash can be the right policy tools which can be harnessed to complement fiscal policy.”

Afzanizam said through Waqf, redistribution of income and wealth can be more equitable and effective, and would lessen the need to introduce new taxes as the wealthy could be more than willing to take part.

MIDF Research chief economist Dr Kamaruddin Mohd Nor concurred that the NEP 2.0 should make way for the poor to better themselves and improve their livelihood.

“Education, training and income generating programmes with direct assistance and guidance are vital to raise their income.

“Assessing the effectiveness of existing programmes and their respective weaknesses are key elements to ensure the success of the programme,” he said.

Kamaruddin said the improvement of the rakyat’s wellbeing, regardless of social orientation, should be the government’s primary objective.

“Equitable distribution of wealth should be promoted via various skill enhancement programmes to enable faster social mobility.

“More customised social economic programmes are essential to address unique characteristics of various categories of the rakyat,” he said.

Anwar's Election Result in Port Dickson

https://www.freemalaysiatoday.com/category/nation/2018/10/13/gods-will-that-anwar-leads-malaysia-says-nazri/

Hypocrites like Nazri and libelers like Saiful, thought they can fool honest people. They are wrong. They can only fool idiots and people with black hearts.

Many people, like Daim Zainuddin, accused Anwar of being a hypocrite by pretending to be better than he really is, meaning, by abstaining from women and alcohol, Anwar pretends to be holier than what he actually is.

Many people also accused Anwar of being power crazy, so impatient to gain power that Anwar is willing to sacrifice the Malay race by breaking its unity. Unity in disgrace is stupidity and cruel. Just because you are evil, do not expect other people to be evil as well.

That power craziness of Anwar is easy to prove to be false. Look at all the ass lickers in UMNO. They still remained with UMNO because they are the real power crazy people. Anwar left because he stuck to his principle. Justice and fairness above others, not even unity or power. Anwar could just have tolerated all the corruption and injustices around him, if he had wanted to become Prime MInister quickly.

If Anwar were the holy men type, he would have just joined PAS, where he was most welcomed, but he did not. Anwar enjoyed his life with activities such as horse riding where he broke his neck. I heard, Anwar even went Scuba diving.

Anwar even tolerated corruption around him as long as he is not aware of it. I heard that during the UMNO battle to capture Sabah from UMNO, Anwar's operation room smelled of money. Even in the PD election, he went to the Army camp and attend dinners sponsored by his supporters, which were questionable election practises by an incumbent political party. There were other practises that Anwar was accused of, which just proved that Anwar was flexible, not extremist. If you want extremist, go to PAS and DAP. Even, they were duped into doing questionable practises.

I still remembered very well why chinese hated Anwar. Anwar was deemed as racist for allowing non-Mandarin certified teachers to become Principals in Mandarin schools. Anwar should have stuck to fhis principle that the best qualified should be the leader, not based on some racial prejudice. True to his style, Anwar gave in. So now, the racist practises made victims of teachers like my colleague's wife, a Mandarin-speaking but not certified teacher, because she teaches English and Maths, will never be considered for promotion to become a Principal.

That is the weakness of Anwar. He is too flexible. In contrast to Mahathir. My nature of character favours Anwar's style, but that does not mean that success will be guaranteed. I hate Mahathir's style, but sometimes, that is what is needed.

Better Alternative to ROAD TOLLS based on Switzerland

https://www.youtube.com/watch?v=J6OfpgOZdoY
I agree with Dr. Mahathir or even Najib. Ridiculous to remove tolls especially for people who do not use highways.
Unfortunately a promise is a promise. We can still fulfill the promise by twisting some of the words, while making highways more efficient.

Some highways need their tools to be removed because they are not conducive to free flow of vehicles. Also ;difficult to enforce the proposed method of charging highway use.
The solution is to use highway permits. Instead of tolls, use highway permits as used by Switzerland especially for tourists. We can do the same and charge tourists higher for the use of highways.
You may say it is the same as tolls, but not really. It does not stop the flow of traffic. It makes travelling to highways much faster and more efficient.
For tourists, it is not fair because we have to pay for the whole year when we only use it for two days, so I do not use it.
For the Malaysian case, we can make it more affordable by not breaking our finances. Special highway permits during special occasions, at rates that are much lower than current tool rates. We can even make it permit free for these occasions but this is not advisable.
Malaysians should pay some lah. It will allow more people to use the non toll roads, and it will not congest the highways so much also.
As for subsidizing the highway by lowering the cost of the permit, this is not true because under heavy use, the cost of tolls should be much less. More people using the highway the cheaper it becomes because highways do not consume much resources once built. Only depreciation and maintenance costs which should be much less once divided among more users.
https://en.wikipedia.org/wiki/Motorways_of_Switzerland
The Swiss autobahn/autoroute system requires the purchase of a vignette (toll sticker) — which costs 40 Swiss francs — for one calendar year in order to use its roadways, for both passenger cars and trucks.[4] The Swiss vignette is offered only as an annual toll sticker. Trucks also have to pay a toll based on the tonnage and the distance.
