「爸爸,為什麼班上同學都去造冊打疫苗只有我不行?」
台北市滿12足歲的七年級學童已於9月22日陸續接種BNT
而這一波符合資格的學童依中央的規定必須是在2009年9月1日前出生的才符合造冊資格
但這也導致有不少家長來找我陳情:「只因為自己的孩子生日在9月1日過後就無法被造冊,更導致全班只有少數幾個人被排擠在疫苗接種之外,造成孩子心中的相對剝奪感及家長嚴重的不安感」
耿葳透過台北市校務系統調閱今年9月2日到12月31日期間滿12足歲的學童人數,發現全台北市居然高達6,938人
今天一早在教育委員會中,特別針對這樣的問題與教育局長討論
如果疫苗是戰略物資,學童接種疫苗是達到校園免疫的必要手段
那麼就不應該讓今年在9月1日後滿12足歲的孩子成為這一波的疫苗孤兒
因此,耿葳也具體要求台北市政府教育局,必須針對這樣的狀況向中央爭取,目標是讓今年12月31日前滿12足歲的學童都能進入下一階段的造冊,並催促中央儘快讓疫苗到位以安排接種
讓孩子們在校園可以免於染疫風險,也可以讓校園的防疫更加完備與穩定

📜 [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.

陳奕迅《我們》(電影「後來的我們」主題曲)小提琴版本 | Violin cover by AnViolin of《Us》by Eason Chen
電影上映時創造出超~~多金句,陳奕迅的歌聲幫這部電影推到最催淚的程度,整首歌沒有一個愛字,卻充滿了無能為力的愛。
從去年開始的疫情,大家應該更能體會很多事情不一定要等到預設時機才去做,很多話沒馬上說,以後可能沒對象講了。愛情如此,親情更是如此。
用小提琴表現聽起來好像更加淒涼了,希望大家體會出這種遺憾,及時表達愛!
