Oh just another normal Sunday. Not. I’m crouched at the farthest corner of the couch, petrified, and screaming like a makcik. Nerf gun war happening in my living room. What is wrong with these people??! Main Barbie dolls je boleh tak? #nashsazzy #thenashes #imaanlilytiararose
Tonight's dinner : Korean Fried Chicken Toast RM13.90 with FREE latte (from Moonfest 2021 voucher that my sis have 😍❤️, normal sugar, I thought less sugar 😋) and she bought potato salad to share for the family 🤤
.
Tasty. Love the texture and combo for the toast. It has kimchi, scrambled egg, lettuce, juicy fried chicken and I love the toast, chewy.
.
The potato salad is also nice. It has a freshness to it. Chunky potatoes 🥔 and crunchy cucumber slices 🤤 👍🏼 i think add a mixture to bread also nice like spread 🤣 nooo I need to stop with bread.
.
My sis better not ask me what else I wanna eat 🤣🤣🤣

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

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.

今日のテーマは、「食べ過ぎは何日後に太るのか？」です。
「食べ過ぎた！太る！どうしよう！」
そんな風に思ったこと、ありませんか？
普段は健康的な食生活を目指して暮らしていても、たまたまストレスが溜まってたくさん食べてしまったり、タイミング的にお祝いごとが続いたりして、たくさん食べてしまうケースは、誰にでもありえます。
でも、食べ過ぎたと思ったら、意外と大丈夫だった…って思ったことありませんか？
今回は、食べ過ぎると体にどんな変化が起こるのか、食べ過ぎてから何日後に太るのか、研究論文を紹介しながら、整理してみたいと思います。
