Happy World Heart Day! ❤❤❤
Heart disease is the world’s number one killer but new advances help us better understand how to keep hearts beating better and for longer💪
@fitbit is driven by the desire to make the world a healthier place, which includes your heart health!

If you own a @fitbitsg Sense, you are able to use the Electrocardiogram (ECG) app to assess your heart rhythm for atrial fibrillation (AFib), a heart rhythm irregularity. It’s so simple to use, all you have to do is open the app on your smart watch, hold your fingers on the corners around the watch while being still for 30 seconds. After assessing your heart rhythm, you’ll receive a reading from the app showing you if your heart rhythm appears normal or signs of AFib.

Let's work towards keeping our heart healthy with better nutrition, ample sleep, activity and stress management💟🌈

So I usually review earbuds ranging from the budget options to the premium ones, and mostly, I am always excited to review and test them out.

However, this Nothing Ear 1, for me, believe it or not, wasn’t something that I was “dying” to check out because I am never a fan of overhyped products, especially earbuds.

There are usually only two ends of the spectrum, it’s either going to sound GOOD or it’s going to sound BAD, then there are the other compromises that come with it, like the comfort, ease of use, battery life and of course the price.

So where does this Nothing Ear 1 stand then? Well, let me tell you where.

📜 [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.

As a person who is constantly moving about, I do tend to forget where I leave stuff from time to time and well, Apple may have helped solve that problem for me.

Introducing the AirTag. It is a small tracker that helps you find your stuff. Now trackers are nothing new as Tile trackers have been around for the longest time but honestly, there has not been a tracker so far that is as convenient as the AirTag.

So, in this video, I will share with you everything that you need to know about the Apple AirTags and I will give you a definite answer on who this tracker is for and whether or not it is worth it.

Ever had someone offering you a business opportunity?
Ever rejected someone because you are afraid you are gonna be in a scam!
What if this is legit? Have you ever thought to yourself about it?

If you're so afraid then stay stuck. But if you want change, take risks but do it wisely!

Here's my take on this because I was once a huge skeptic and the one who has given all these excuses to everyone who dare offer me an opportunity. Until I knew if I want change in my life, I have to step out of my comfort zone and be smart about it.

And now I have found the right company and right system to take me to where I want to be! If you want to give yourself this chance then drop me a message on either of my channels.❤️

But if you refuse to accept what I say and stay in your made-up beliefs then by all means, stay ☺️ Stay and Do nothing. But don't complain. Go eat ice cream. Stay stuck.

?????????????????

Be grateful for everything, because what you have, you will be given more. But if you have no gratitude, then what you have will also be taken away.
