愛情故事

緣起緣滅

聚散分離

無一倖免

愛不涉及對錯

而是一種勇敢

讓我們更了解自己

即使不能走到最後也能互相祝福

感謝曾愛過的彼此

也願你繼續相信愛情

哪怕追尋千里萬里

剛剛開始彼此那種決心
明明懸崖都肯一起俯瞰
人人問起我的男生
人人亦都妒忌這麼襯

可惜今天彼此抱得再緊
仍然難逃將關係來劃分
同諧白髮美麗的謠傳失了真
才無奈接受你是個完美缺陷

要發生 始終發生
並未能像個童話於八十歲給你入廚做甜品
無情是
我再和你如何美滿恩愛
分手一剎卻毫無原因

明白 我再流連也是總不配
是兩種命 是兩種人
當決意放手不忿是不忿
如何逆轉 害人緣份
無奈 有愛無緣情人總吸引
越帶希望 越見傷神
尤其是雙方的差距如此近
但你的吻 最後只可吻別人

應該怎麼拋開你這個人
從前曾投資生命和耐心
如何目送這段感情由淺到深
難行入最後半步我們欠了運

要轉身 只好轉身
道別還未算殘忍
很努力也總要別離便殘忍
難逃避碰上誰也仍然與你比較
只可給予這人同情分

明白 我再流連也是總不配
是兩種命 是兩種人
當決意放手不忿是不忿
如何逆轉 害人緣份
無奈 有愛無緣情人總吸引
越帶希望 越見傷神
尤其是今天跟所有人擁吻
沒你的吻那樣迫真 動魄驚心

明白 我再流連也是總不配
沒這種運 做對新人
差半吋也許跟教堂很近
人很越近 越無緣份
無奈有愛無緣情人總吸引
是最宿命 又最感人
尤其是 你共我的確如此襯
但我只配注定今生愛別人

📜 [專欄新文章] Gas Efficient Card Drawing in Solidity

✍️ Ping Chen

📥 歡迎投稿： https://medium.com/taipei-ethereum-meetup #徵技術分享文 #使用心得 #教學文 #medium

Assign random numbers as the index of newly minted NFTs

Scenario

The fun of generative art NFT projects depends on randomness. The industry standard is “blind box”, where both the images’ serial number and the NFTs’ index are predetermined but will be shifted randomly when the selling period ends. (They call it “reveal”) This approach effectively solves the randomness issue. However, it also requires buyers to wait until the campaign terminates. What if buyers want to know the exact card right away? We’ll need a reliable onchain card drawing solution.

The creator of Astrogator🐊 isn’t a fan of blind boxes; instead, it thinks unpacking cards right after purchase is more interesting.

Spec

When initializing this NFT contract, the creator will determine the total supply of it. And there will be an iterable function that is randomly picking a number from the remaining pool. The number must be in range and must not collide with any existing ones.

Our top priority is accessibility/gas efficiency. Given that gas cost on Ethereum is damn high nowadays, we need an elegant algorithm to control gas expanse at an acceptable range.

Achieving robust randomness isn’t the primary goal here. We assume there’s no strong financial incentive to cheat, so the RNG isn’t specified. Implementers can bring their own source of randomness that they think is good enough.

Implementation

Overview

The implementation is pretty short and straightforward. Imagine there’s an array that contains all remaining(unsold) cards. When drawIndex() is called, it generates a (uniform) random seed to draw a card from the array, shortens the array, and returns the selected card.

Algorithm

Drawing X cards from a deck with the same X amount of cards is equal to shuffling the deck and dealing them sequentially. It’s not a surprise that our algorithm is similar to random shuffling, and the only difference is turning that classic algo into an interactive version.

A typical random shuffle looks like this: for an array with N elements, you randomly pick a number i in (0,N), swap array[0] and array[i], then choose another number i in (1,N), swap array[1] and array[i], and so on. Eventually, you’ll get a mathematically random array in O(N) time.

So, the concept of our random card dealing is the same. When a user mints a new card, the smart contract picks a number in the array as NFT index, then grabs a number from the tail to fill the vacancy, in order to keep the array continuous.

Tweak

Furthermore, as long as the space of the NFT index is known, we don’t need to declare/initialize an array(which is super gas-intensive). Instead, assume there’s such an array that the n-th element is n, we don’t actually initialize it (so it is an array only contains “0”) until the rule is broken.

For the convenience of explanation, let’s call that mapping cache. If cache[i] is empty, it should be interpreted as i instead of 0. On the other hand, when a number is chosen and used, we’ll need to fill it up with another unused number. An intuitive method is to pick a number from the end of the array, since the length of the array is going to decrease by 1.

By doing so, the gas cost in the worst-case scenario is bound to be constant.

Performance and limitation

Comparing with the normal ascending index NFT minting, our random NFT implementation requires two extra SSTORE and one extra SLOAD, which cost 12600 ~ 27600 (5000+20000+2600) excess gas per token minted.

Theoretically, any instantly generated onchain random number is vulnerable. We can restrict contract interaction to mitigate risk. The mitigation is far from perfect, but it is the tradeoff that we have to accept.

Healthy & yummy 🥮~ Black Sesame Paste Mixed Nuts Mooncakes 黑芝麻五仁广式月饼 ~ 传统五仁月饼的馅中有杏仁、桃仁、花生仁、麻仁和瓜子仁，在家做可随意搭配自己喜欢的果仁，少油也比较健康！🤗

The recipe for making mixed nuts mooncakes is versatile, you can mix and tweak as many types of nuts and dried fruits combinations as you desired. I have added some black sesame paste in the fillings to replace the use of oil. This is a healthier alternative to mooncakes that uses oil, lard, and sweetened bean paste fillings.
