🌻Morgan Stanley Mid-year Investor Outlook: A tricky transition
https://www.morganstanley.com/ideas/midyear-2021-global-markets-outlook
🌻在您投資生涯中, 有沒有一些觀念讓您受用很多?
下面這位投資名人的好觀念影響我很深. 他的意思是, 一般投資人, 只要能説出三個買一家公司的理由, 就很夠了. 這也迫使我, 每次在買股票時, 問自己對這家公司的了解有多少. 也會去衡量公司的優點與缺點在哪裡.
"It is vital (重要的) that you know what you own, that if I asked you on the street why you like a certain stock, you can give me three reasons. If you don't know how they make their money, who their key clients are and what they make if, then I will tell you that you are over your head and should not own individual stocks."
全文在此:
Jim Cramer: In Times Like This, Go for the Easy Money
Look at the stocks you own. Can you tell me why you've got them? If you can't answer the following three questions, then have a look at several I like right now.
We've endured the meme stock craziness, with all of its love for heavily shorted stocks. We have watched the collapse of bitcoin to levels viewed as shocking, even if they are still more than double where they were not that long ago. We've dealt with Fed officials making it clear that they are no longer on the side of the bulls or the bears. They are on the side of job growth, but are wary of inflation. We've seen the end of the rush to get vaccines, which means that millions of people are going to get the new COVID variant, because there is no natural immunity to it. We've watched as the hopes for an infrastructure bill have collapsed. We've endured shortages of everything from chips to plastic to imported goods and labor.
And we're still standing, yeah, yeah, yeah.
Yep, we are in one of those halcyon moments, where the masks are off -- even if they shouldn't be -- and Americans are back doing what they do best: consume, spend, go out to eat and then consume and spend some more.
There are times in the stock market where the collective mindset is revealed. This is one of those times: Things are cool, it's not a big moment, there's no real news for a bit, it's the historically strong period and we can reach some conclusions about where we are.
When things are like this, it is important to remember that buyers like to revert to tried-and-true companies that thrive no matter what. These are companies that have an edge and are better at what they do than other companies.
You know that I am a great believer in index funds, that the average person doesn't have the time or the inclination to research individual stocks. It's a difficult barrier. I think you need to make time to read the quarterly report and listen to the conference call, to Google articles and, if possible, get some research about the companies you own. It is vital that you know what you own, that if I asked you on the street why you like a certain stock, you can give me three reasons. If you don't know how they make their money, who their key clients are and what they make if, then I will tell you that you are over your head and should not own individual stocks. I am reminded by this, because, once again, without a mask, I can be recognized and if I am not holding "Nvidia the Second," I can carry on a conversation.
I have had many in the last two weeks and when I have asked this litany of questions, I find myself at a loss as to why almost no one knew what they owned. But they thirsted for individual stocks, because they, like me, think things are better post pandemic. No, that's not a facetious comment. Many, many stocks did better with a stay-at-home economy. A huge number.
So what do I do? I revert to what others do when you are stumped about how to stay in touch with stocks, but want to do less homework. That means buying stocks that are accessible, not stocks like Unity (U) or Snowflake (SNOW) or Twilio (TWLO) or Okta (OKTA) .
I revert to normal businesses people know and I suggest they Google some articles, peruse the conference call, but, above all, like the company's products so you can buy more if it goes down.
Here's some that I have been telling people I like:
First is Ford (F) . I think the Ford lineup is amazing. The electric F-150 series will be incredible. I am eager to get a Maverick for my family, because it is a smaller pickup that will get the job done for the myriad little things I need to do with this farm I bought from that crazy bitcoin foray. I like the competitive edge of the CEO, who says he is going to bury Elon Musk when the Lightning comes out. I even think the Bronco is cool as all get out. Most important, though? I think the chip shortage is ending. My semiconductor friends are telling me the foundries are producing more feature-rich chips and that means Ford can pump out the trucks small business people love and need. Plus, the used car prices at last have plateaued, according to their most important pricing index. Halcyon times.
Second, Costco (COST) : The samples are coming back. Tell me you don't love the samples. You need things in bulk. You want low prices. You want to get all of the things that people don't think of with Costco, like insurance, hearing-aids -- hey, they are a fortune -- jewelry, things around the house. You go and you will buy far more than you first came for. My kind of store.
The kids love this American Eagle Outfitters (AEO) , which we just bought for my charitable trust, which you can follow along by joining the Action Alerts PLUS club. Jay Schottenstein, the CEO, came on "Mad Money" recently and it's clear that his Aerie model has real staying power: 26 consecutive quarters of double digit growth. No flash in the pan, that one. Number one brand in jeans for the 15 to 25 year old group. The best in the mall. How did I know this? I see the credit card bills.
I got up this morning to do my physical therapy. I have been doing it ever since I hurt my back in February. I have this really cool pair of sneakers that fit me perfectly and I love them, but I am fortunate enough to have a vacation house and I am always taking those shoes with me.
So I went on Amazon (AMZN) this morning and lo and behold I saw them for half price. I bought two pairs. Then I went over everything I have bought in the last year and got a bunch of those things. Then I bought a pair of binoculars, because mine were stolen. I paid half price.
Yep, Amazon's universal. I was talking to Alexa, while I was ordering, getting some new music on, asking questions. I saw that despite all of the Sturm und Drang of Amazon being late with things, all the delivery dates were within range. I didn't click on any ads, and I didn't need the speed of Web Services, but the whole thing reminded me about how special the darned company is. I don't care if it's ahead or behind plan for the moment. I would just buy some more when it goes down.
Finally, Apple (AAPL) . I think people who don't own Apple should look what they are holding at this very moment. Yes, right now. Or look at what's in your lap or on the table besides your fork. And then think about the bill you paid last night without knowing it. Think about what you bought in the App store yesterday. Think about what would happen if it would break or get stolen or, left in the Uber (UBER) , or heaven forbid, be dropped into the pool or in the, yes, toilet.
There, that's what you buy in halcyon times. Stocks of companies you know that if they go lower, because things get less halcyon, you are fine with it and buy more. If things go up, believe me, you will participate.
So accept the moment. Don't try for the hard money. Go for the easy kind. That's the best kind.

最近 Funliday-旅遊規劃 常發一些精選旅遊回憶的 App 通知給使用者,在去年十一二月的時候發通知 Server 還能撐的了瞬時大流量的 request。
但今年開始發這類通知,總共發了三次,三次都造成 Server 被打掛,而且重開 AP 還緩解不了,瞬間手足無措。大概都要等過了十分鐘左右,Server 才將這些 request 消化完。
這裡就來簡單整理一下時間軸,順便分享一下 Funliday 是如何解決這個問題。
---
* 1/6 1900:系統排程發送精選旅遊回憶的 App 通知
* 1/6 1900+10s 開始:Server 收到極大量的 request
* 1/6 1900+20s:Nginx 出現錯誤訊息 1024 worker not enough,並回傳 http status code 503
* 1/6 1900+25s:PostgreSQL 出現錯誤訊息 could not fork new process for connection (cannot allocate memory)
* 1/6 1900+38s:Node.js 收到 PostgreSQL 的 exception。There was an error establishing an SSL connection error
* 1/6 1900+69s:PostgreSQL 出現錯誤訊息 database system is shut down
* 1/6 1900+546s:PostgreSQL 出現錯誤訊息 the database system is starting up
---
看了時間軸就覺得奇怪,先不論 10s 的時候發了極大量 request,造成 20s 在 Nginx 出現 worker not enough 的錯誤訊息。而是要關注 25s 時的 PostgreSQL 出現 could not fork new process for connection 的錯誤訊息。
Funliday 用了同時可承載 n 個 connection 的資料庫,而且程式碼又有加上 connection pool,理論上根本不該出現這個錯誤訊息。但整個時間軸看下來感覺就是 PostgreSQL 的 capacity 問題,造成系統無法運作。
因為就算將 Nginx 的 worker connection size 再加大 10 倍,只是造成 PostgreSQL 要接受的 request 也跟著被加大 10 倍,但 PostgreSQL 那裡因為 request 變多,原本在 69s 直接關機的時間點只會提早,而無法真正緩解這個狀況。
基於以上狀況,小編就開始回去看自己的程式碼是不是哪裡寫錯了。會這樣想也是覺得 PostgreSQL 應該沒這麼弱,一下就被打掛,一定是自己程式碼的問題 Orz
---
這邊來分享一下自己程式碼的寫法,圖一是原始寫法,在每個 API 都 create 一個 db client instance 來處理該 API 層的所有 db request。這是蠻單純的做法,也是 day 1 開始的處理方式。但有個小問題,就是每個 API 層都要自己 create instance,不好管理,且浪費資源。
後來因為想要做 graceful shutdown 的關係,所以調整了一下 db client instance 的建立方式,用 inject 將 instance 綁在 request 上面,如圖二。這樣只要在 middleware 建立 db client instance 就好,好管理,而且只要有 req 就可以取得 instance,非常方便。而這也是 1/6 時的程式碼,就從這裡開始研究吧。
---
直接切入 node-postgres 的文件,認真讀了一下 pool 有下面兩種使用方式:
1. pool.connect, pool.release:文件寫著 checkout, use, and return,光看描述就應該用這個沒錯。
2. pool.query:適用於不需要 pool 的連線方式,文件上也清楚寫著內部實作是直接 call client.query,所以用了這個方式是完全跟 pool 扯不上邊。
但偏偏小編從 day 1 用的就是第 2 種方式 Orz,雖然看起來應該是寫錯,但也是要修改後實測,才知道是不是真的可以解決問題。
---
如圖三,這是修改後的程式碼。想了一下子,覺得目前在 API 層使用 req.pool.query 還不錯,不想用官方的建議做法:先 create client,然後 query 之後,再使用 release。
如果照官方建議做法,API 層的程式碼會多一堆與商業邏輯無關的程式碼,也不好維護。所以在不想動到 API 層的程式碼,只能使用 monkey patch 的方式來達到這個需求。
monkey patch 可以將原方法利用類似 override 的方式,將整個方法改掉,而不改變 caller 的程式碼,這也是 JavaScript, Ruby, Python 這類動態語言的特性之一,但真的要慎用,一不小心就會把原方法改成完全不同意義的方法了。
所以原本應該要在 API 層實作 connect, query, release 一大堆程式碼,可以用 monkey patch 完美解決這一大堆程式碼。
---
在 dev 壓測後至少 capacity 可以達到原本的 4 倍以上,隔天實際上 production 之後也確實如壓測般的數據,可以承載目前的流量。
其實這篇分享的重點只有一點,文件看仔細才是最重要的事啦!如果沒把文件看仔細,然後開發經驗也不足的話,什麼 RCA、monkey patch 都幫不上忙啦!
---
後記:有夠丟臉,其實完全用不到圖三,只要把圖二的 pool creation 放到最外層就好了,因為 pool.query 的內部實作已經有做 connect, query, release 了。
感謝下面的 Mark T. W. Lin 及 Rui An Huang 的幫忙,實在是太搞笑了 Orz

the fork app 在 Travel with Winny 一起跟昀去旅行 Facebook 的最佳解答
【澳洲外食省錢分享】最近省錢模式大開,只要出去外食就會去找有特價的餐廳😆 最常用的就是 TheFork.au 跟 EatClub 這兩個 APP📱
The Fork 就常有 30%~50% off 的餐廳,而且可以提前預訂😁 像上個禮拜請我爸吃父親節的餐廳就是打五折😆
Eat Club 是限時特價,例如突然肚子餓了想外食,就可以看看上面有什麼餐廳這個時段有打折😊
First Table 則是需要付預訂費,之後到那邊餐廳才會打折👀
有些朋友可能會覺得打折餐廳食物不好吃,但其實是看評價啦!我個人覺得聚餐是為了聊天,畢竟每個人預算不同😅 如果真的想要吃大餐,可以自己找伴侶或是更熟的朋友一起去吃🍴
Ps. 不知道台灣有沒有類似這樣的網站或 APP 呢?😊 不然澳幣暴跌,我回台灣需要努力省錢啊 😂
Pss. 話說好多紐西蘭朋友搬來澳洲~ 尤其黃金海岸天氣溫和,更吸引大家來養小家庭☀️
