{Giveaway} Children's Day is coming and thanks to Ergoworks Singapore, two of you will get to win these IMPACT Ergo-Comfort Casual Backpacks!
As mentioned in my previous post, we have been using IMPACT bags for many years as it is the only ergonomic brand internationally endorsed and recommended by Singapore Physiotherapy Association and The Chiropractic Association (Singapore).
So far, all the kids' school bags have lasted for a long time and we can bear testimony to not just the functional design, which promotes better spinal health, but the high quality and durability as well.
To spread love this Children's Day, here is your chance to win an IMPACT - IPEG-D01 - Ergo-Comfort Casual Backpack in your choice of colour (Aqua/Black/Peach).
This bag comes with a main front as well as multiple organiser compartments. It is the lightest of ergonomic bags in its category and weighs merely 450grams. The striking colours and casual yet useful design of this backpack get our thumbs up.
To join the giveaway,
🎒 Follow A Happy Mum and Ergoworks Singapore.
🎒 Like and share this post.
🎒 Leave a comment on why you would like to win this ergonomic bag.
🎒 Tag at least 3 friends with young kids, 1 in each comment. Each counts as an entry.
This giveaway ends on 8 Oct 2359hrs. Note that the winners will have to self-collect their prizes from Ergoworks. One winner will be chosen from FB and the other from IG. The IG winner will win a different bag design so hop over to join too. This giveaway is not endorsed by or affiliated with FB or IG. Good luck!

📜 [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.

Inami is most well known for its extensive wood carving district which traces its origins to the construction of the Inami Betsuin Zuisen-ji Temple in 1390. This temple, entirely made of wood and ornamented with intricate carvings has a long history of burning down only to be rebuilt in a much more extravagant fashion. The temple was most recently rebuilt during the Meiji period in 1885, and now exists as the largest wooden Pureland Buddhist temple in the Hokuriku region. It was officially designated as "one of the prefecture's important cultural assets" on April 1, 1965.
Because of its rich history, wood carving is the major trade in Inami. During the reconstruction of the temple in the mid 18th century woodcarvers from Kyoto were dispatched to help in the rebuilding process. These helpers ushered in a new era of woodcarving in Inami, and local carpenters began to produce a more varied assortment of carvings than the temple pieces they had focused on previously.Presently, the woodcarvers use over 200 different variations of chisels to complete their works. They are considered to be the most skilled woodcarvers Japan.
The sound of the Inami woodcarving district was chosen in 1996 as one of the 100 Soundscapes of Japan.
Hey guys!
Finally sharing our first flat update... we cover a few topics in this video.
First, sharing some of the other flats we considered and why they didn't work for us/why we chose this one in the end, second, sharing a lot of the renovation materials we've chosen, and lastly, some eye candy of home decor we've purchase so far! Hope you guys enjoy!
Also, i realised after filming, i had a list of questions i had noted from the flat tour video which i forgot to answer in this video. Since it's already so long, i thought i'd include it in the next update. Leave any other questions below, and i will deffo remember to include them next time!
Meanwhile, check out my instagram for (almost) daily outfits @wenwenstokes as well as my story highlight "Ldn Penthouse" for any more recent updates.

"Song of the Ancients" is one of the most famous soundtracks from NieR series. It appears at so many games including NieR Replicant, NieR Gestalt, NieR Automata, and FFXIV YorHa: Apocalypse. There are so many versions of arrangement from those OST albums, I highly recommend you to hear them out.
