今天天氣也太熱~~~太適合在家吹冷氣了XD
分享最近的愛歌給大家~~~可以反覆聽好幾遍

前幾天不是分享最近都在追韓劇「出軌的話就死定了」，過程中的劇情都很喜歡，走懸疑搞笑浪漫路線，就是收尾時超快速有點超出我的想像啊！欸，哪會按呢？

目前追的是「上流謊言」，剛好女主也是曹如晶~只是比較痛苦的是還沒完結篇所以每週都要等最新集數出來太難熬啦！

Uh, uh, uh (hey)
I was thinking 'bout her (uh), thinking 'bout me (hey)
Thinking 'bout us (us), what we gon' be (hey)
Opened my eyes, yeah, it was only just a dream (hey)
So I travelled back (uh) down that road
Will she come back? (Back) No one knows
I realize, yeah, it was only just a dream
I was at the top and now it's like I'm in the basement
Number one spot and now she found her a replacement
I swear now I can't take it
Knowing somebody's got my baby
And now you ain't around baby I can't think
I should've put it down, should've got the ring
'Cause I can still feel it in the air
See her pretty face, run my fingers through her hair
My love of my life, my shawty, my wife
She left me, I'm tight
'Cause I knew that it just ain't right
I was thinking 'bout her (uh), thinking 'bout me (hey)
Thinking 'bout us (us), what we gon' be (hey)
Opened my eyes, yeah, it was only just a dream (hey)
So I travelled back (uh) down that road
Will she come back? (Back) No one knows
I realize, yeah, it was only just a dream
When I be ridin', man, I swear I see her face at every turn
Tryna get my Usher on but I can't let it burn
And I just hope she know that she the only one I yearn for
More and more I miss her, when will I learn?
Didn't give her all my love, I guess now I got my payback
Now I'm in the club thinking all about my baby
Hey, she was so easy to love
But wait, I guess that love wasn't enough
I'm going through it every time that I'm alone
And now I'm missing, wishing she'd pick up the phone
But she made the decision that she wanted to move on
'Cause I was wrong
I was thinking 'bout her (uh), thinking 'bout me (hey)
Thinking 'bout us (us), what we gon' be (hey)
Opened my eyes, yeah, it was only just a dream (hey)
So I travelled back (uh) down that road
Will she come back? (Back) No one knows
I realize, yeah, it was only just a dream (uh, uh, hey)
If you ever loved somebody put your hands up (put your hands up)
If you ever loved somebody put your hands up
And now they're gone and you're wishing
You could give them everything (everything, hey)

📜 [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.

Reinventing Workers for the Post-COVID Economy

The nation’s economic recovery from the COVID-19 pandemic will hinge ( ) to some extent ( ) on how quickly show managers can become electricians ( ), whether taxi drivers can become plumbers ( ), and how many cooks can manage software for a bank.

This is likely to prove especially problematic for millions of low-paid workers in service industries like retailing ( ), hospitality ( ), building maintenance and transportation, which may be permanently impaired ( ) or fundamentally transformed. What will janitors ( ) do if fewer people work in offices? What will waiters do if the urban restaurant ecosystem never recovers its density ( )?

Their prognosis ( ) is bleak ( ). Marcela Escobari, an economist at the Brookings Institution, warns that even if the economy adds jobs as the coronavirus risk fades ( ), “the rebound won’t help the people that have been hurt the most.”

Looking back over 16 years of data, Escobari finds that workers in the occupations ( ) most heavily hit since the spring will have a difficult time reinventing themselves. Taxi drivers, dancers and front-desk clerks have poor track records moving to jobs as, say, registered nurses, pipe layers or instrumentation technicians.

COVID is abruptly ( ) taking out a swath ( ) of jobs that were thought to be comparatively ( ) resilient ( ), in services that require personal contact with customers. And the jolt ( ) has landed squarely on workers with little or no education beyond high school, toiling ( ) in the low-wage service economy.

“The damage to the economy and particularly to workers will probably be longer lasting than we think it is going to be,” said Peter Beard, senior vice president at the Greater Houston Partnership, an economic development group.

What’s more, he said, COVID will intensify underlying ( ) dynamics ( ) that were already transforming ( ) the workplace. Automation ( ), for one, will most likely accelerate ( ) as employers seek to protect their businesses from future pandemics

The challenge is not insurmountable ( ). Yet despite scattered ( ) success stories, moving millions of workers into new occupations remains an enormous ( ) challenge.

“We need a New Deal ( ) for skills,” said Amit Sevak, president of Revature, a company that hires workers, trains them to use digital tools and helps place them in jobs. “President Roosevelt deployed ( ) the massive number of workers unemployed in the Great Depression on projects that created many of the dams ( ) and roads and bridges we have. We need something like that.”

勞工轉型以因應後疫情時代經濟

美國經濟能否從新型冠狀病毒影響下復甦，將在一定程度上取決於表演經理們要多久才能變成電工，計程車司機能否化身為水管工，以及有多少廚師能替銀行管理軟體。

這對零售業、餐旅業、建築維修和運輸業等服務業數百萬低薪工人來說，問題恐怕特別大。這些行業可能受到永久性損害或發生根本性改變。若辦公室裡人變少了，工友要做什麼呢？若都市餐廳生態系統繁盛不再，服務生又該如何？

他們的前景是黯淡的。布魯金斯學會經濟學家Marcela Escobari警告說，即使就業機會隨新型冠狀病毒疫情風險消退而增加，「經濟反彈也幫不了那些受創最重的人」。

Escobari檢視16年來的數據發現，今春以來受衝擊最大的一些職業，勞工將很難自我改造。計程車司機、舞者和櫃檯人員轉行從事護理師、舖管工或儀器技工等工作者十分有限。

新型冠狀病毒突然帶走了一大批原本被認為較不容易永久消失的工作，即需與客戶面對面接觸的服務工作。這一衝擊直接打擊到那些僅受過高中教育、在低薪服務經濟區塊中掙扎的勞工。

經濟發展組織大休士頓商會資深副總裁Peter Beard表示：「經濟、尤其是勞工們受害的時間，可能比我們預期的還要更長。」

他說，更重要的是，新型冠狀病毒疫情將強化已經在改變職場的潛在動力，自動化即為一例，由於雇主力求讓自己的企業未來不受大疫情影響，自動化極可能加速。

這項挑戰並非不能克服。然而，儘管有少數成功的例子，讓數百萬勞工轉業仍是巨大的挑戰。

雇用勞工後培訓他們使用數位工具，並幫他們找到工作的Revature公司總裁Amit Sevak說：「我們需要一項針對職業技能的新政。小羅斯福總統大蕭條時期把大量失業勞工投入工程計畫，興建了我們現在使用的水壩、道路與橋樑。我們需要這樣的東西。」

Baby back, couple racksCouple Grammys on him, couple plaquesThat's a fact, throw it backThrow it back
我回來了 帶著滿架子的獎牌
葛萊美拿了好幾座 白金唱片得了一堆
這一切鐵證如山
所以趕快轉過去熱舞來討好我
And this one is for the championsI ain't lost since I beganFunny how you said it was the endThen I went did it again
這是獻給稱霸的冠軍
踏上路以來 我從來就未曾迷失
你不覺得好笑嗎？ 酸民說我玩完了
但我回來了 又大獲全勝

I told you long ago on the roadI got what they waiting for
I don't run from nothing, dogGet your soldiers, tell 'em I ain't layin' low
早在那條老街上 我就說了吧
我有大家引頸期盼的東西
我可不會隨便逃跑
所以告訴你的大軍 我沒有要低調引退的意思
You was never really rooting for me anywayWhen I'm back up at the top, I wanna hear you sayHe don't run from nothin', dogGet your soldiers, tell 'em that the break is over
反正你也從來沒喜歡過我
當我重返榮耀 我要聽到你說
「他不會輕易離場」
所以集結你的大軍 告訴他們休息時間結束了

Need to get this album doneNeed a couple number onеsNeed a plaque on every song
Need mе like one with Nicki now

But these niggas bitches like Madea
告訴嘻哈饒舌仔 我眼裡根本沒有你
我就像小賈斯汀一樣 流行到爆
妹子？我沒興趣 我是酷兒
你們這些酸民就像個老媽子一樣

let's do it
I ain't fall off, I just ain't release my new shit
I blew up, now everybody tryna sue me
You call me Nas, but the hood call me Doobie
開工吧
我沒有跌落神壇 我只是新歌還沒發
我一夕爆紅 現在每個人都想告我
你們叫我Nas 但我家鄉的人叫我Doobie

[Jack Harlow]
My track record so clean, they couldn't wait to just bash meI must be gettin' too flashy, y'all shouldn't have let the world gas me
我沒拿什麼獎 他們等不及就說我沒實力
我肯定是太招搖了 你們不該讓全世界噴爆我
It's too late 'cause I'm here to stay and these girls know that I'm nastyI sent her back to her boyfriend with my handprint on her ass cheek
太遲了 因為老子我已經要在這裡待下
妹子們都愛我
讓我在她的翹臀上留下紅紅的掌印
再回去找她男朋友

City talkin', we takin' notesTell 'em all to keep makin' postsWish he could, but he can't get close
OG so proud of me that he chokin' up while he makin' toasts
I'm the type that you can't control, said I would, then I made it so
謠言四起 我們做著筆記
告訴大家繼續po文吧
他只是羨慕 但他永遠趕不上我
嘻哈大老們為我驕傲 他敬酒的時候還在哽咽
我完全不受控 我就是說到做到

I don't clear up rumors, where's y'all sense of humor?
I'm done makin' jokes 'cause they got old like baby boomers
Turned my haters to consumers, I make vets feel like they juniors
Say your time is comin' soon, but just like Oklahoma
我從來沒在闢謠的 你們難道都沒幽默感嗎
我也不想在開玩笑了 不然怎麼講都是老梗
把我的酸民變粉絲 讓老兵變年輕
你說你的時代已經要來了
Mine is comin' sooner, I'm just a late bloomerI didn't peak in high school, I'm still out here gettin' cuter
All these social networks and computersGot these pussies walkin' 'round like they ain't losers
但我的時代來的更快 我是大器晚成
我在高中不受歡迎 但現在我越來越討喜
這些鍵盤戰士 總是故意說著妹子怎樣 顯得自己比較不魯

Maguro means Tuna, Zuke means to marinate, and Don is short for Donburi which means rice bowl. Marinated fresh Sashimi-grade tuna served on a rice bowl. Quick yet delicious!

You can of course use Salmon, scallop, or any other Sashimi-grade fish instead! Enjoy :)

---------------------------------
Maguro Zuke Don (Marinated Tuna Fish Rice Bowl)

Difficulty: Very Easy
Time: 15min
Number of servings: 1

Ingredients:
90g (3.2oz) Sashimi Grade Yellowfin Ahi Tuna
1/2 tbsp. Sake
1/2 tbsp. Mirin (sweet Sake)
1 tbsp. soy sauce
Wasabi if you like
1 bowl of rice
Kizaminori (shredded Nori sheet)
green onions and/or Shiso leaf
toasted white sesame seeds

Directions:
1. In a small pot, boil down Sake and Mirin to reduce the alcohol content.
2. Add soy sauce and Wasabi, then mix well. (Wasabi will be not spicy if you mix and leave for a while, so kids can eat it with only nice Wasabi aroma.)
3. Marinate tuna Sashimi and put in the fridge for about 10 minutes. (Do not marinate too long or tuna will be salty.)
4. Meanwhile, put rice in a rice bowl and leave to cool. (Cold rice is better because it won't warm up the fish.)
5. Put Kizaminori on the rice, arrange Tuna sashimi, garnish with green onions or Shiso leaves, and sprinkle with toasted white sesame seeds. You can place a bit of fresh Wasabi on top if you like.
