【國立臺灣大學 109學年度畢業典禮 校長致詞】
Opening Remarks, National Taiwan University Commencement 2021
President Dr. Chung-Ming Kuan

.
各位師長同仁，各位畢業同學以及家長們，歡迎大家參加 109 學年度的線上畢業典禮。

去年新冠疫情初起，學校雖仍舉辦實體的畢業典禮，但規模大為縮小，許多師生和家長均以無法參加典禮為憾。今年初臺灣的疫情持續穩定，大家原本期待今年畢業典禮能按照往年方式辦理。不料五月時疫情急轉直下，臺北市疫情警戒程度提高，我們於是推遲畢業典禮，並改以線上方式進行。這也是臺大首次以線上方式舉辦畢業典禮。

隨著疫情發展，線上活動如今已成為生活中的新常態。我們雖逐漸習慣線上教學，線上會議，線上交流，線上購物訂餐等，但連期待了四年的畢業典禮也只能在線上參加，許多同學與家長們難免失望。為此，學務處與許多同學攜手，精心策劃了今天這場特殊的線上畢業典禮，希望能讓大家留下不一樣，但仍美好的記憶。

因為新冠疫情，有些同學會抱怨：這樣大的疫情怎麼就正好被我們在畢業時碰上了？也有些同學則樂觀的想，一旦有了疫苗，疫情得到控制，世界最終還是會回到以前的軌道，大家仍可以過著平穩安定的日子。

然而這個世界從不曾平靜。今年畢業的同學多數出生於1999 年，那正是規模達 7.3 的 921 大地震發生的那一年。時隔四年，亞洲（包括臺灣）爆發了罕見的急性呼吸道感染病 SARS。不過五年之後，源自美國的金融海嘯席捲全球，影響全世界經濟數年之久。2009 更是不平靜的一年，臺灣出現莫拉克風災，造成慘重傷亡；全球則爆發了 H1N1 流感大流行，數十萬人因此死亡。這些當時都曾被認為是數十年（甚至百年）一遇的重大災難。

回顧二十多年來的這些事件（這還僅僅是一部份與臺灣相關的事件），我們就會發現：巨大的天災人禍，過去曾頻繁出現，未來應該也不會少見。

當然，新冠疫情的影響範圍遠超過 SARS 與 H1N1 流感，對世界的衝擊則更大於金融海嘯。近代能與這次疫情相比的是一百年前 (1918-1920) 的全球流感大流行；據後來估計，當時全世界人口三分之一染疫，約有五千萬人因此不幸喪生。

那次流感爆發時正值第一次世界大戰末期，對當時的德軍主力造成嚴重打擊。而後疫情時代，戰敗的德國被列強宰割，奧匈帝國及奧圖曼帝國亦隨之瓦解，徹底改變了舊的國際秩序，也為後來的世局（從歐陸，到中東和亞洲）埋下許多不安定的種子。

這次新冠疫情並未伴隨著世界大戰，但出現在國際強權針鋒相對，世界產業供應鏈重整的關鍵時刻；後疫情時代因此充滿不確定性。而重組後的國際政經秩序，我不知道那會是一個「美好或不美好的新世界」*，但它就是大家必須面對的世界。那裡將充滿挑戰和機會，如何善用所學回應挑戰，如何從機會中脫穎而出，都是大家新的功課。這些功課沒有標準答案，你們必須自己解答，自己審閱答案。

我也希望利用這個機會提醒同學們，對於正在醫療前線奮戰的眾多醫護人員，其中包括了許多學校師長與大家的學長姐們，我們一定要心存感念。當疫情大浪襲來時，他們勇往直前，力挽狂瀾，不僅保護病人，也捍衛著臺灣社會。他們是真正的英雄。只要大家共同努力，疫情終會過去，我們一定會贏得抗疫的最後勝利。

最後，我謹代表所有老師和行政主管，向所有畢業同學們表達最深切的祝福，也恭喜辛苦多年的家長們。敬祝大家未來一切順利，身體健康
最後我還想講幾句話。我記得我看過一篇外國人寫的文章，他說他在臺灣多年，注意到臺灣有個很奇怪的習慣，朋友分手時都常常會說：「要小心哦」。我看到這篇文章的時候，也突然心有所感；多年來我媽媽每次看到我出門時會跟我講這句話，而後來我跟自己的小孩，也會講這樣的話。所以在畢業典禮這個時刻，我敬祝大家未來一切順利，身體健康，大家都要小心哦！

==============================

.
When the COVID-19 pandemic began last year, NTU was still able to hold graduation ceremonies in person but on a much smaller scale and with the absence of many faculty members, students, and parents. Earlier this year, we were hoping to gather for a traditional commencement. But the sudden outbreak in May had forced Taipei City to raise its epidemic alert level. So we postponed the Commencement and made the decision to hold the ceremony virtually. This is the first virtual Commencement in NTU history.

To our faculty, new graduates, and parents, welcome to the National Taiwan University’s Commencement celebration for the Class of 2021.

As the pandemic unfolds, digital is the new normal. While we gradually adapt to online learning, virtual meetings, social media, online shopping, and food delivery, it is inescapably disappointing for many students and parents to have to celebrate the achievements of our graduates this way after anticipating this event for four years. And because of this, the Office of Student Affairs has teamed up with the graduates to ensure that this unique virtual Commencement is a moment that everyone will remember fondly in the future.

Some of you may ask, "why does this happen just when we are graduation?" And some of you may think optimistically that once the vaccines are available and the pandemic is contained, the world will be back to normal, and that we will all live peacefully.

But the world has never been peaceful. Most of the graduates this year were born in 1999, when the magnitude 7.3 earthquake happened on September 21. Four years after, SARS broke out in Asia, including Taiwan. Within another 5 years, the financial crisis, originated in the United States, affected global economies for years. In 2009, Typhoon Morakot landed and caused severe casualties in Taiwan; the H1N1 flu pandemic took hundreds of thousands of lives. These disasters were, at the time, seen as rare catastrophes that would only take place once every few decades, or even centuries.

Looking back to the past 20 years, we’d notice that, even just in Taiwan, catastrophes have never been in short supply. And they will probably never be in the future either.

Of course, the effect of COVID is far beyond SARS and H1N1, and its impact is greater than the financial crises. What came close was the Spanish flu that took place a century ago (1918-1920), when, according to estimation, one-third of the global population was infected and about 50 million people died.

The influenza pandemic outbreak took place at the end of WWI and hit the German military especially hard. And after the pandemic, Germany was forced to cede its territories to the great powers. What followed was the fall of the Austro-Hungarian and the Ottoman Empires. The series of events reset the international order and formed the settings for many conflicts in the years to come.

While COVID did not break out during a world war, it came at a critical time when great powers bicker and the global supply chains face a reform. The post-pandemic ear is therefore full of uncertainty. I don’t know whether it’d be a "Brave New World"* once the international political and economic orders are reshuffled. But it will be a world we have to live in. There will be many challenges and opportunities, and it will be our new task to utilize what we have learned to tackle challenges and grasp opportunities. Unlike any standardize
d test, you will have to answer and grade the answers yourselves.

I also want to use this opportunity to remind the graduates, that we must have appreciation and gratitude for the healthcare workers who are on the frontlines fighting. Many of them are our faculty members and alums. When the waves of the pandemic hit, they stood up to save lives and protect Taiwan’s society. They are true heroes. As long as we work together, we will weather the crisis and win this battle.

Finally, on behalf of the faculty and management, I send you our deepest best wishes. And congratulations to the parents and families who have supported the graduates for years. I wish you success and good health.

One final thing, I remember reading an article by a foreign writer who said he had lived in Taiwan for years and had noticed that Taiwanese people have a strange habit of saying "be careful" when they part ways. When I read the article, this resonates with me from the heart. For years, my mother would say the same thing whenever I am leaving the house. Now I say the same thing to my children, too. So at this Commencement ceremony, I wish everyone great success in the future, good health, and "be careful."

0. Intro

The announcement of Uniswap v3 is no doubt one of the most exciting news in the DeFi place recently 🔥🔥🔥

While most have talked about the impact v3 can potentially bring on the market, seldom explain the delicate implementation techniques to realize all those amazing features, such as concentrated liquidity, limit-order-like range orders, etc.

Since I’ve covered Uniswap v1 & v2 (if you happen to know Mandarin, here are v1 & v2), there’s no reason for me to not cover v3 as well ✅

Thus, this article aims to guide readers through Uniswap v3, based on their official whitepaper and examples made on the announcement page. However, one needs not to be an engineer, as not many codes are involved, nor a math major, as the math involved is definitely taught in your high school, to fully understand the following content 😊😊😊

If you really make it through but still don’t get shxt, feedbacks are welcomed! 🙏

There should be another article focusing on the codebase, so stay tuned and let’s get started with some background noise!

1. Uniswap & AMM recap

Before diving in, we have to first recap the uniqueness of Uniswap and compare it to traditional order book exchanges.

Uniswap v1 & v2 are a kind of AMMs (automated market marker) that follow the constant product equation x * y = k, with x & y stand for the amount of two tokens X and Y in a pool and k as a constant.

Comparing to order book exchanges, AMMs, such as the previous versions of Uniswap, offer quite a distinct user experience:

AMMs have pricing functions that offer the price for the two tokens, which make their users always price takers, while users of order book exchanges can be both makers or takers.

Uniswap as well as most AMMs have infinite liquidity¹, while order book exchanges don’t. The liquidity of Uniswap v1 & v2 is provided throughout the price range [0,∞]².

Uniswap as well as most AMMs have price slippage³ and it’s due to the pricing function, while there isn’t always price slippage on order book exchanges as long as an order is fulfilled within one tick.

In an order book, each price (whether in green or red) is a tick. Image source: https://ftx.com/trade/BTC-PERP

¹ though the price gets worse over time; AMM of constant sum such as mStable does not have infinite liquidity

² the range is in fact [-∞,∞], while a price in most cases won’t be negative

³ AMM of constant sum does not have price slippage

2. Tick

The whole innovation of Uniswap v3 starts from ticks.

For those unfamiliar with what is a tick:

Source: https://www.investopedia.com/terms/t/tick.asp

By slicing the price range [0,∞] into numerous granular ticks, trading on v3 is highly similar to trading on order book exchanges, with only three differences:

The price range of each tick is predefined by the system instead of being proposed by users.

Trades that happen within a tick still follows the pricing function of the AMM, while the equation has to be updated once the price crosses the tick.

Orders can be executed with any price within the price range, instead of being fulfilled at the same one price on order book exchanges.

With the tick design, Uniswap v3 possesses most of the merits of both AMM and an order book exchange! 💯💯💯

So, how is the price range of a tick decided?

This question is actually somewhat related to the tick explanation above: the minimum tick size for stocks trading above 1$ is one cent.

The underlying meaning of a tick size traditionally being one cent is that one cent (1% of 1$) is the basis point of price changes between ticks, ex: 1.02 — 1.01 = 0.1.

Uniswap v3 employs a similar idea: compared to the previous/next price, the price change should always be 0.01% = 1 basis point.

However, notice the difference is that in the traditional basis point, the price change is defined with subtraction, while here in Uniswap it’s division.

This is how price ranges of ticks are decided⁴:

Image source: https://uniswap.org/whitepaper-v3.pdf

With the above equation, the tick/price range can be recorded in the index form [i, i+1], instead of some crazy numbers such as 1.0001¹⁰⁰ = 1.0100496621.

As each price is the multiplication of 1.0001 of the previous price, the price change is always 1.0001 — 1 = 0.0001 = 0.01%.

For example, when i=1, p(1) = 1.0001; when i=2, p(2) = 1.00020001.

p(2) / p(1) = 1.00020001 / 1.0001 = 1.0001

See the connection between the traditional basis point 1 cent (=1% of 1$) and Uniswap v3’s basis point 0.01%?

Image source: https://tenor.com/view/coin-master-cool-gif-19748052

But sir, are prices really granular enough? There are many shitcoins with prices less than 0.000001$. Will such prices be covered as well?

Price range: max & min

To know if an extremely small price is covered or not, we have to figure out the max & min price range of v3 by looking into the spec: there is a int24 tick state variable in UniswapV3Pool.sol.

Image source: https://uniswap.org/whitepaper-v3.pdf

The reason for a signed integer int instead of an uint is that negative power represents prices less than 1 but greater than 0.

24 bits can cover the range between 1.0001 ^ (2²³ — 1) and 1.0001 ^ -(2)²³. Even Google cannot calculate such numbers, so allow me to offer smaller values to have a rough idea of the whole price range:

1.0001 ^ (2¹⁸) = 242,214,459,604.341

1.0001 ^ -(2¹⁷) = 0.000002031888943

I think it’s safe to say that with a int24 the range can cover > 99.99% of the prices of all assets in the universe 👌

⁴ For implementation concern, however, a square root is added to both sides of the equation.

How about finding out which tick does a price belong to?

Tick index from price

The answer to this question is rather easy, as we know that p(i) = 1.0001^i, simply takes a log with base 1.0001 on both sides of the equation⁴:

Image source: https://www.codecogs.com/latex/eqneditor.php

Let’s try this out, say we wanna find out the tick index of 1000000.

Image source: https://ncalculators.com/number-conversion/log-logarithm-calculator.htm

Now, 1.0001¹³⁸¹⁶² = 999,998.678087146. Voila!

⁵ This formula is also slightly modified to fit the real implementation usage.

3. Concentrated liquidity

Now that we know how ticks and price ranges are decided, let’s talk about how orders are executed in a tick, what is concentrated liquidity and how it enables v3 to compete with stablecoin-specialized DEXs (decentralized exchange), such as Curve, by improving the capital efficiency.

Concentrated liquidity means LPs (liquidity providers) can provide liquidity to any price range/tick at their wish, which causes the liquidity to be imbalanced in ticks.

As each tick has a different liquidity depth, the corresponding pricing function x * y = k also won’t be the same!

Each tick has its own liquidity depth. Image source: https://uniswap.org/blog/uniswap-v3/

Mmm… examples are always helpful for abstract descriptions 😂

Say the original pricing function is 100(x) * 1000(y) = 100000(k), with the price of X token 1000 / 100 = 10 and we’re now in the price range [9.08, 11.08].

If the liquidity of the price range [11.08, 13.08] is the same as [9.08, 11.08], we don’t have to modify the pricing function if the price goes from 10 to 11.08, which is the boundary between two ticks.

The price of X is 1052.63 / 95 = 11.08 when the equation is 1052.63 * 95 = 100000.

However, if the liquidity of the price range [11.08, 13.08] is two times that of the current range [9.08, 11.08], balances of x and y should be doubled, which makes the equation become 2105.26 * 220 = 400000, which is (1052.63 * 2) * (110 * 2) = (100000 * 2 * 2).

We can observe the following two points from the above example:

Trades always follow the pricing function x * y = k, while once the price crosses the current price range/tick, the liquidity/equation has to be updated.

√(x * y) = √k = L is how we represent the liquidity, as I say the liquidity of x * y = 400000 is two times the liquidity of x * y = 100000, as √(400000 / 100000) = 2.

What’s more, compared to liquidity on v1 & v2 is always spread across [0,∞], liquidity on v3 can be concentrated within certain price ranges and thus results in higher capital efficiency from traders’ swapping fees!

Let’s say if I provide liquidity in the range [1200, 2800], the capital efficiency will then be 4.24x higher than v2 with the range [0,∞] 😮😮😮 There’s a capital efficiency comparison calculator, make sure to try it out!

Image source: https://uniswap.org/blog/uniswap-v3/

It’s worth noticing that the concept of concentrated liquidity was proposed and already implemented by Kyper, prior to Uniswap, which is called Automated Price Reserve in their case.⁵

⁶ Thanks to Yenwen Feng for the information.

4. Range orders: reversible limit orders

As explained in the above section, LPs of v3 can provide liquidity to any price range/tick at their wish. Depending on the current price and the targeted price range, there are three scenarios:

current price < the targeted price range

current price > the targeted price range

current price belongs to the targeted price range

The first two scenarios are called range orders. They have unique characteristics and are essentially fee-earning reversible limit orders, which will be explained later.

The last case is the exact same liquidity providing mechanism as the previous versions: LPs provide liquidity in both tokens of the same value (= amount * price).

There’s also an identical product to the case: grid trading, a very powerful investment tool for a time of consolidation. Dunno what’s grid trading? Check out Binance’s explanation on this, as this topic won’t be covered!

In fact, LPs of Uniswap v1 & v2 are grid trading with a range of [0,∞] and the entry price as the baseline.

Range orders

To understand range orders, we’d have to first revisit how price is discovered on Uniswap with the equation x * y = k, for x & y stand for the amount of two tokens X and Y and k as a constant.

The price of X compared to Y is y / x, which means how many Y one can get for 1 unit of X, and vice versa the price of Y compared to X is x / y.

For the price of X to go up, y has to increase and x decrease.

With this pricing mechanism in mind, it’s example time!

Say an LP plans to place liquidity in the price range [15.625, 17.313], higher than the current price of X 10, when 100(x) * 1000(y) = 100000(k).

The price of X is 1250 / 80 = 15.625 when the equation is 80 * 1250 = 100000.

The price of X is 1315.789 / 76 = 17.313 when the equation is 76 * 1315.789 = 100000.

If now the price of X reaches 15.625, the only way for the price of X to go even higher is to further increase y and decrease x, which means exchanging a certain amount of X for Y.

Thus, to provide liquidity in the range [15.625, 17.313], an LP needs only to prepare 80 — 76 = 4 of X. If the price exceeds 17.313, all 4 X of the LP is swapped into 1315.789 — 1250 = 65.798 Y, and then the LP has nothing more to do with the pool, as his/her liquidity is drained.

What if the price stays in the range? It’s exactly what LPs would love to see, as they can earn swapping fees for all transactions in the range! Also, the balance of X will swing between [76, 80] and the balance of Y between [1250, 1315.789].

This might not be obvious, but the example above shows an interesting insight: if the liquidity of one token is provided, only when the token becomes more valuable will it be exchanged for the less valuable one.

…wut? 🤔

Remember that if 4 X is provided within [15.625, 17.313], only when the price of X goes up from 15.625 to 17.313 is 4 X gradually swapped into Y, the less valuable one!

What if the price of X drops back immediately after reaching 17.313? As X becomes less valuable, others are going to exchange Y for X.

The below image illustrates the scenario of DAI/USDC pair with a price range of [1.001, 1.002] well: the pool is always composed entirely of one token on both sides of the tick, while in the middle 1.001499⁶ is of both tokens.

Image source: https://uniswap.org/blog/uniswap-v3/

Similarly, to provide liquidity in a price range < current price, an LP has to prepare a certain amount of Y for others to exchange Y for X within the range.

To wrap up such an interesting feature, we know that:

Only one token is required for range orders.

Only when the current price is within the range of the range order can LP earn trading fees. This is the main reason why most people believe LPs of v3 have to monitor the price more actively to maximize their income, which also means that LPs of v3 have become arbitrageurs 🤯

I will be discussing more the impacts of v3 in 5. Impacts of v3.

⁷ 1.001499988 = √(1.0001 * 1.0002) is the geometric mean of 1.0001 and 1.0002. The implication is that the geometric mean of two prices is the average execution price within the range of the two prices.

Reversible limit orders

As the example in the last section demonstrates, if there is 4 X in range [15.625, 17.313], the 4 X will be completely converted into 65.798 Y when the price goes over 17.313.

We all know that a price can stay in a wide range such as [10, 11] for quite some time, while it’s unlikely so in a narrow range such as [15.625, 15.626].

Thus, if an LP provides liquidity in [15.625, 15.626], we can expect that once the price of X goes over 15.625 and immediately also 15.626, and does not drop back, all X are then forever converted into Y.

The concept of having a targeted price and the order will be executed after the price is crossed is exactly the concept of limit orders! The only difference is that if the range of a range order is not narrow enough, it’s highly possible that the conversion of tokens will be reverted once the price falls back to the range.

As price ranges follow the equation p(i) = 1.0001 ^ i, the range can be quite narrow and a range order can thus effectively serve as a limit order:

When i = 27490, 1.0001²⁷⁴⁹⁰ = 15.6248.⁸

When i = 27491, 1.0001²⁷⁴⁹¹ = 15.6264.⁸

A range of 0.0016 is not THAT narrow but can certainly satisfy most limit order use cases!

⁸ As mentioned previously in note #4, there is a square root in the equation of the price and index, thus the numbers here are for explantion only.

5. Impacts of v3

Higher capital efficiency, LPs become arbitrageurs… as v3 has made tons of radical changes, I’d like to summarize my personal takes of the impacts of v3:

Higher capital efficiency makes one of the most frequently considered indices in DeFi: TVL, total value locked, becomes less meaningful, as 1$ on Uniswap v3 might have the same effect as 100$ or even 2000$ on v2.

The ease of spot exchanging between spot exchanges used to be a huge advantage of spot markets over derivative markets. As LPs will take up the role of arbitrageurs and arbitraging is more likely to happen on v3 itself other than between DEXs, this gap is narrowed … to what extent? No idea though.

LP strategies and the aggregation of NFT of Uniswap v3 liquidity token are becoming the blue ocean for new DeFi startups: see Visor and Lixir. In fact, this might be the turning point for both DeFi and NFT: the two main reasons of blockchain going mainstream now come to the alignment of interest: solving the $$ problem 😏😏😏

In the right venue, which means a place where transaction fees are low enough, such as Optimism, we might see Algo trading firms coming in to share the market of designing LP strategies on Uniswap v3, as I believe Algo trading is way stronger than on-chain strategies or DAO voting to add liquidity that sort of thing.

After reading this article by Parsec.finance: The Dex to Rule Them All, I cannot help but wonder: maybe there is going to be centralized crypto exchanges adopting v3’s approach. The reason is that since orders of LPs in the same tick are executed pro-rata, the endless front-running speeding-competition issue in the Algo trading world, to some degree, is… solved? 🤔

Anyway, personal opinions can be biased and seriously wrong 🙈 I’m merely throwing out a sprat to catch a whale. Having a different voice? Leave your comment down below!

6. Conclusion

That was kinda tough, isn’t it? Glad you make it through here 🥂🥂🥂

There are actually many more details and also a huge section of Oracle yet to be covered. However, since this article is more about features and targeting normal DeFi users, I’ll leave those to the next one; hope there is one 😅

If you have any doubt or find any mistake, please feel free to reach out to me and I’d try to reply AFAP!

Stay tuned and in the meantime let’s wait and see how Uniswap v3 is again pioneering the innovation of DeFi 🌟

Hello friends! Today we're going to share with you how to make a French style chocolate and vanilla cake: Chocolate Marble Cake (Marbré Au Chocolat).

Marbré Au Chocolat, aka Chocolate Marble Cake is an iconic French store-bought dessert. It’s traditionally baked in a loaf tin in France. This cake is very moist and not sweet, it’s a perfect treat for any time of the day.

This is a simple recipe and very easy to make, it tastes like pound cake, but the taste is richer and buttery, butter gives lots of flavor. And one serving of cake can taste the flavors of vanilla and cocoa. Heartily recommend. 💕

How to make French Chocolate Marble Cake
Here is the French Chocolate Marble Cake Recipe

☞  Mold size: 16x7x6cm

✎ Ingredients
unsalted butter 100g
powdered sugar 100g
egg 2, about 110g
vanilla extract 1.3g
honey 9g
All purpose flour 110g
baking powder 1.3g
cocoa powder 9g
a pinch of salt

✎ Instructions
1. Grease the cake pan with butter, then line with parchment paper.
2. Use a mesh strainer to sift powdered sugar. Then sift flour and baking powder together. Set aside.
3. Place softened butter and a pinch of salt into a large mixing bowl. Using a hand mixer on medium speed to cream the butter for 4-5 minutes, or until butter is pale yellow and fluffy. Use a rubber spatula to scrape the sides of the bowl once or twice while mixing.
4. Add half sugar and mix for 1 minute, then add the rest of sugar and vanilla extract, then  mix for another 1 minute.
5. Add honey, and add egg one by one, and mix well after each egg is added. Scraping down the sides of the bowl as necessary.
6. Add the half sifted flour and baking powder, fold it in gently with spatula until the flour has disappeared. Repeat again with the remaining flour until well combined.
7. Simply pour 2/3 of the cake batter into a piping bag. Set aside.
8. Add the cacao powder into the rest of 1/3 of the batter and slowly mix it in until combined. Then pour the cacao batter into another piping bag.
9. Once the two cake batters are ready, it's time to combine them to create the marble effect. Cut off the tip and pipe the batter into the cake pan, alternating between the two colors.
10. After placing all the batters, you can use a fork, a bamboo stick or a butter knife to swirl the batters together. It's the fun part of the recipe, you can create your own marble pattern. Now the cake is marbled and ready to bake.
11. Preheat the oven to 200C, and bake for 15 minutes, then reduce the temperature to 160C, bake for 22~24 minutes.
12. Once baked, remove the cake from the pan, and let cool on the rack.
