Surrounded by Comfort and FUN with @pampers_sg new premium shipper and Pampers Premium Care!!
We are slowly transiting from diaper tapes to diaper pants, and our Pampers Premium care helped enable her move with great ease due to its stretchability, S-Curve design and minimal Sag due to excellent absorbency and even distribution of liquid across diaper!
You can find their new Premium Shipper (box) is now exclusively available on Lazada. It has very cute cartoons and prints that your baby can unleash his/her creativity by drawing and colouring on! Tomorrow is also Pampers’ Lazada Super Brand Day! There is going to be great promotions, giveaways and deals available!
On top of that, Pampers is running a contest! Buy the new premium care shipper from Lazada. Share you and your child’s creative use of the Premium Care boxes and stand to be one of the 3 winners to win 3 months supply of Premium Care Pampers (worth $330)!
Simply upload the picture of the end product with you and baby on your IG, explain how you and your baby creatively used the Premium Shipper box, tag 2 friends, @pampers_sg, #PampersImagineNation and #pampersclub to qualify. Remember to make your post public.
Contest ends on 27 October and winners will be announced on @pampers_sg. The three most creative answers will win! Can’t wait to see all the exciting posts! 😊

📜 [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.

回收短訊要在兩分鐘;那月餅盒呢?你有兩周時間!
MGM 美高梅 澳門今年的三式八味月餅禮盒不僅有多樣口味可選,禮盒圖案更是周游軒小朋友及其父親以澳門美高梅藝術收藏「八面靈龍」為靈感而設計。寓意著八方進寶、闔家團圓,也突出了純潔童真的可貴。小朋友的創意無限,用水彩和油墨繪製了這一幅天馬行空的作品。享用過美味月餅後,不妨活用月餅盒的儲物能力,譬如製成顏色筆盒,變廢為寶?
🔸澳門環境保護局於9月21日(#中秋節)至10月7日在全澳各區設置約800個月餅盒回收點,方便市民回收不再重用的月餅盒。大家亦可以積極響應政府「回收月餅盒好Easy」的號召,更多詳情在https://bit.ly/3hRYUVP,為持續貫徹資源回收獻出自己的一份力!
🔸MacauEat 將會推出一系列有關可持續發展和綠色餐飲系列的專題介紹和創作,如果大家有什麼好提議的話,歡迎inbox 我們,讓我們從餐飲出發,令社區變得更好。
This year, MGM offers three kinds of mooncake gifts boxes in eight flavours. The special design comes from little local artist Chao Iao Hin, and his father. This art piece is inspired by the “Valkyrie Octopus”at MGM MACAU, which embodies auspicious and happy reunion of families, as well as the precious innocence of children. After enjoying the mooncakes with families, you might as well try making a good use of the containers. Turning it into a watercolour markers box is probably a good idea to carry out the resource recycling.
🔸You may also respond to government’s 「Mooncake Boxes Recycling」campaign, recycle the mooncake boxes in designated sites. Check the details in our bio’s link!
🔸 MacauEat will also promote a series of work and creation in terms of the green talkings and happenings in our local f&b industry. DM us if you have more related ideas and stay tuned!
