Seoul to Finland (26/09/2021)
After 16 hours, we arrived safely in Vaasa, Finland last night. It was a long, exhausting, challenging yet interesting & exciting journey. Well at least for me. 🥲
To answer your question, for now, we’ll stay here until next year (all depends on Kim’s work).
Can’t wait to share more of our experience living in this happiest country in the World.
Till then, here’s some photodump from yesterday.

吐瓦魯呼籲 承認台灣人民進入聯合國機構場域的權利
吐瓦魯總理拿塔諾表示聯合國成立的宗旨在於服務及保護全世界人民，所有人民進入此一國際大家庭，都不應受到阻礙，這是所有人民的權利，而非部份人民的特權。
台灣人民無法參訪聯合國及參與會議，台灣媒體和記者也未被允許入場採訪聯合國會議及活動，進入聯合國場域竟是以國籍而非以安全為考量，這是不具正當理由的，聯合國的公民空間和新聞自由正被限縮。
吐瓦魯呼籲，承認台灣人民進入聯合國機構場域的權利，允許台灣護照持有者進入聯合國場域，是台灣和台灣人民有意義參與聯合國體系的重要關鍵。
台灣的夥伴價值，值得聯合國重視。

Thanks to #Tuvalu Prime Minister Kausea Natano for his speech urging the UN to grant Taiwanese people and press access to UN premises during the General Debate of #UNGA76:
"Mr. President, I thank you for the recognition that to build resilience, we must respect the rights of people and that the UN must be revitalized to uphold the rights of all people of the world—people it was established to serve and protect.
On this very note, Tuvalu calls for the recognition of the rights of the people of Taiwan to the UN premises. The UN system was established to serve the public interest of all peoples. Having unhindered access to the family of nations should be a right for all, not a privilege for some.
It is most regrettable to see the ongoing injustice of Taiwanese people being barred from accessing UN premises for visits and meetings simply because the UN fails to recognize Republic of China (Taiwan) passports, which are, in fact, accepted by almost every country in the world. Likewise, Taiwanese media outlets and journalists cannot obtain accreditation to cover UN meetings and events.
It is alarming that civic space in the UN and freedom of the press are being restricted. It is also unjustifiable that a person’s access to UN premises now depends on nationality rather than on safety and security grounds. Granting Taiwanese passport holders access to UN premises is an essential step for the meaningful participation of Taiwan and the Taiwanese people in the UN system."
Taiwan's vision of global partnership can serve as a valuable reference for the UN.

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.

Meditation Instructions:
Lay down on a comfortable position. Start focusing on your breath and let your inner chatter go away. Imagine yourself surrounded by a brilliant light as you close your eyes.
Bring your awareness to your spirit guides and ask them to protect you as you fall into deep sleep.
Ask them to walk this light thru your chakras as the music changes from a frequency to another, removing all the negative energies, balancing these centers and clearing your Aura.
When you wake up the next morning, sit on your bed and take several deep breaths. Then drink a glass of water before eating your breakfast.
The number of times a week you should do this meditation depends on how you feel about your energy. You may use this meditation when you're feeling low on energy or. By cleansing your aura daily you rid yourself of negative energies that you’ve picked up from other people and the environment so you may use it as a prevention to keep you on a high vibration
