Starbucks Duy Tân – nước đi “cáo già” của ông lớn ngành cafe

Hôm nay 23/4 là ngày khai trương cửa hàng thứ 10 của Starbucks tại Hà Nội, toạ lạc tại một toà nhà riêng rất đẹp đẽ tại 32 – 34 phố Duy Tân, ngay cạnh The Coffee House.

Theo trend thì trước đây khi mới có 9 cửa hàng, thì gần 90% số stores (8 trên tổng số 9) là đều nằm trong khuôn viên của một khách sạn/ tổ hợp nào đó (ví dụ IPH, Somerset, Asia Tower Nha Tho…); duy chỉ có 1 store riêng một building ở ngã tư Bà Triệu; vậy tại sao đến store thứ 10, Starbucks lại chọn xây hẳn một cửa hàng độc lập, mà lại ở phố Duy Tân trong khi cách đó 800m đã có 1 store tại IPH?

1, Phố Duy Tân là phố hội tụ các toà nhà văn phòng của các công ty lớn, như FPT, BIDV, Vietin, Novotel, VPB, Viettel, CMC…; đánh đúng vào đối tượng khách hàng là dân văn phòng, doanh nhân, người nước ngoài… Starbucks mong muốn đây sẽ là nơi lý tưởng cho đối tượng này gặp gỡ đối tác, làm việc,… nơi mà không gian của những chuỗi cafe khác như Highlands hay TCH không thể sánh kịp.

2, Có thể nói đây là Starbucks đầu tư nhất ở Hà Nội hiện giờ, với việc decor cực kì ổn & chuẩn; cạnh tranh trực tiếp với 3 hãng cafe lớn trên cùng trục đường (TCH, HL, TBC), Starbucks đang muốn lôi kéo những khách hàng quen của các hãng khác về thành tập khách hàng của chính mình. Chắc chắn rằng những người muốn đặt chân vào những Twitter, TCH khi nhìn qua chiếc ‘dinh tự’ Starbucks kia sẽ suy nghĩ lại về quyết định của mình.

3, Có lẽ đây chính là lý do quan trọng nhất: Ngay bên cạnh là The Coffee House, 36 Duy Tân. Tại số 19 ngay gần đó cũng có một Highlands Coffee. Toà TCH cũng mới khai trương vào 31/1/2018 mới đây. Thường thì khi mở sau, các doanh nghiệp rất ‘ngại’ chạm mặt đối thủ, mà trường hợp này đối thủ lại là ‘hàng xóm’ ngay cạnh. Tại sao Starbucks dám làm điều này? Đó chính là cái ‘cáo già’ của ‘ông lớn’,

Chẳng là, TCH mới đây ra nhánh TCH Signature, có thể nói là ‘nhái’ y hệt mô hình Reserve của Starbucks. Ông lớn không thể ngồi yên để một thằng oắt con giỡn mặt, việc khai trương store mới này cũng chính là ‘signal’ để dằn mặt cho thằng bé thấy là ‘ông này không dễ chơi thế đâu’.

Uber, Starbucks & bàn về độ “sang chảnh” trong chất lượng dịch vụ

Mọi người hay nói mình thích sang chảnh nên mới đi xe Uber nói không với Grab, uống coffee Starbucks chứ không phải là Highlands hay TCH, nhân tiện hôm nay Uber dừng hoạt động mình cũng xin một status nói về vấn đề này.

Ai bỏ tiền ra cũng chỉ mong muốn nhận lại dịch vụ tốt, thái độ nhân viên tốt, đồ uống ngon chứ chắc chắn không một ai muốn bỏ tiền ra để nhận lại những thứ dở cả. Uber & Starbucks là 2 trong số các brands mà mình cảm thấy xứng đáng/ hài lòng khi “ném tiền” vào.

Về Starbucks & the rest

  • TCH cũng 55k/ cốc, Highlands cũng tầm này; nhưng Starbucks thì một cốc cafe bét nhất cũng tầm 80k. Vậy bỏ thêm 25k để làm gì: music, vibes, drinks & quality of service at its best. Ở Starbucks, bạn luôn nhận được nụ cười, sự kiên nhẫn từ nhân viên. Self-serve, vừa thoải mái, nhưng vẫn nhận được sự quan tâm.

Có một câu chuyện thế này vào thứ Sáu vừa rồi: Trên đường đến trường, trời bắt đầu gió & đổ mưa, mình rẽ vào Starbucks trú tạm. Khi nhâm nhi được 1/2 cốc trà thì cũng là lúc hết thời gian sử dụng code wifi trên hóa đơn, mình liền ra xin thêm code wifi để làm việc tiếp, bạn nhân viên cười và nói: “Trời đang mưa gió nên em nghĩ anh cứ lấy thêm 4 code nữa dùng cho thoải mái ạ” và in cho mình 6 codes (~ 6 tiếng sử dụng wifi).

Một việc rất nhỏ nhưng làm cho customers cảm thấy được quan tâm, có thể là do bạn đó, có thể là do Starbucks đào tạo nhân viên tốt; nhưng suy cho cùng, đến với Starbucks thì chắc chắn sẽ nhận lại quality in both drinks & services.

Về Uber & Grab

  • Hôm qua mình có cơ hội được một bác Uber Motor đèo đi. Bác cũng được gần 10000 chuyến rồi. Bác nói nhiều chuyện, mà những câu chuyện này cực kì hay với những người trẻ như mình, bác bảo “Gắn bó cũng lâu rồi cháu ạ, 10000 chuyến, 2 năm trời, bây giờ phải chuyển cũng buồn lắm. Grab có mời bọn bác sang, nhưng bác sẽ phải bắt đầu lại từ đầu.” Mình thấy tiếc cho bác.

Từ lúc mình dùng Uber đến giờ cũng khá lâu rồi, và khi cần gọi xe thì mình sẽ nghĩ đến Uber đầu tiên. Không phải vì Grab mainstream, mà là do khi đi Uber, mình gặp được những người đi cẩn thận, quan tâm đến khách. Trong các chuyến Uber mình đi, chưa bao giờ mình gặp Uber phóng nhanh vượt ẩu, lạng lách…

Có lẽ vì cộng đồng Uber ít, ít chuyến, ít khách nên những tài xế Uber cũng sống chậm hơn chăng?

Còn đi Grab, những gì mình thường xuyên nhận được là những thằng trẻ ranh lái xe, phóng nhanh, đi ẩu mong cuốc hoàn thành nhanh còn kiếm cuốc khác, kiếm thêm tiền…

Hôm nay Uber dừng hoạt động, một vài dòng để chia tay một thương hiệu tốt ở Đông Nam Á, để viết những trải nghiệm của mình về các brands mà mọi người vẫn nghĩ là “sang chảnh”. Chẳng ai sang chảnh được gì ở một vài nghìn thêm cả.

“Sang chảnh” không phải về giá, mà là về chất lượng.

“I was born to love you..”

People often say it is no need to rewatch a movie unless you’d have to, or there’s been some struggles in your life that make you think about the movie.

This man sent me a friend request on Mung 2 Tet (the second day of the lunar new year). I thought “a new year, a new guy, my type, maybe a new beginning?” and I pressed accept. And we started to exchange messages. It was really exciting until I found out that he had already had a husband for himself.

It was kinda funny that I felt like a psycho after just 2 days of talking with him, but I really hoped that he would be happy.

500 days of Summer Tom: "I love how she makes me feel"
I was like Tom in the last 2 or 3 days..

People often say it is no need to rewatch a movie unless you’d have to, or there’s been some struggles in your life that make you think about the movie.

“There’s no such thing as love, it’s a fantasy.” – Summer.

It was a long time since the last time I rewatched “500 Days of Summer”. It IS a great movie, but as the time I first watched it, I was just a high-school boy who once sticked to the slogan “Say NO to love”. But as the time flies, my mind has changed. Every single time I feel sad about my love life or have no belief left in love, I always come back to this movie.

During our lives, we meet people, we go through a lot of different relationships. It’s destiny which brings people together, gives people chances to fall in love.

Summer didn’t believe in love because she was the result of an unhappy marriage and it was not until his husband had she met anyone suitable for her.

“I’m happy. Aren’t you happy?”

Life is so simple provided that people just look for “the happiness” in each other. But they want to label, and to be labeled. It’s all about being called “girlfriend”, “boyfriend”, because people will feel more consistent in doing so.

Summer wanted freedom. She didn’t want to be labeled and made it clear for Tom. But Tom, just like every single man in this World, want to label their relationship. Like me, who want a labeled relationship. Men are so used to keep chasing for something not theirs.

500 days of Summer Tom: "She's not interested in me"

Eventually and also painfully, Tom was just another man in Summer’s past.

But on the bright side, this gave both the opportunity to meet the half of their lives: Summer with her husband, and Autumn (might) be “the one” for Tom.

Although the ending is not a fairy tale as people (including me) might be expecting, but after some days of sadness going on for me lately, this movie is definitely a push for me to find back faith in love. Absolutely gonna find things to do to keep my mind busy, but these things are going to be on my checklist:

– Stop expecting/ overthinking too much: People come and go, you cannot expect someone you like/ love to answer back. I was just expecting too much and imagining what (wouldn’t be happening) too far often.

Just like Tom, turning back to reality just made me collapsed.

– Fate: If people step into your life but isn’t “meant to be”, just don’t stop believing there’s someone out there who is. People don’t just randomly appear, they appear for some reasons.

Summer already had her husband, Tom was still finding his wife.
And I’m just gonna keep on looking for mine 🙂.
“I really do hope that you’re happy.”

Some words for Mung 4 Tet. Hope I will be able to meet my loved one soon!

People seems to overreact to Apple nowadays

Just wanna write some raw thoughts of mine after all the controversies Apple had gone through in 2017. There’re many things to say but I am just gonna write about the latest controversy of Apple.

Back to late 2017, Apple was criticized for slowing down iPhones with worn-out battery. All over Reddit, forums, newspapers…, people were telling them as some devil who slow down old phones to make people upgrade to newer iPhones.

What they’ve done wrong

I don’t say this is right. But old phones and phones with worn-out batteries are totally different. An old phone is like an iPhone 4S, 5, even 6…; which is released many years before the latest. And a phone with worn-out battery is a phone which has a battery capacity much lower than it is designed to be. They are different but people make them the same to make Apple look bad.

I see the only thing Apple did wrong was not telling its customers about this solution they’ve applied to iOS. Rather than that, I see nothing wrong about Apple slowing down these kinds of phones.

Why they did it?

They just wanted to prolong its customer battery life on a single charge, I’ve got an iPhone 6S with 53% battery wear running iOS 11.2.1 and I didn’t even notice any big  difference in performance. I can still check mail, play games, facebooking,… anything that I used to do. That means iOS only goes slow only when your battery is almost unusable.

I got 1.5 – 2 hours of continuous on-screen time and have to charge regularly. But the phone shut itself when there were 10% left. This is what Apple worries about.

They just wanted to extend its product and make customers safe. Just imagine, your battery is worn-out and you have to charge all day, then it is very harmful for you and the product itself. They were doing this just for the good.

What’s the solution for you?

The solution for you is simple as replacing your battery because it’s time to replace it. Cheap, safe, fast. You don’t need to upgrade your phone.

Apple even lowers the battery replacement price down to $29, a very cheap price for almost every people on Earth. I don’t understand why many people don’t just do the right thing (when they have to) but put all the blame on Apple.

Please, give Apple to chance.

Keeping Node.js applications running using Forever

Introduction

You ever had to restart your Node.js instances manually since it was crashed?

Well, I had. And maybe right now you are being stuck in the middle of the situation.

Server gets OOM (Out-of-Memory), it automatically kills Node.js. Runtime exceptions is very likely to kill your application, too.

Worst case, supposed it was in the middle of the night, 3AM for example, when you were continuously getting service-down notifications in your dreams. You’d wish, ‘Hope it could somehow automatically restart for me‘.

Using Forever to keep your app running

As its name describes, forever, will keep your Node.js apps running continuously as a service and it will automatically handle unexpected crashes for you.

Apart from automating the recovery tasks, it will start your server in the child process but a long running process so that your server will still living even though you close the Terminal/ Shell window.

Installing and start daemonizing

  1. You could install forever globally using npm:
  2. After installing, you can now run your node.js application by typing:
    But note that this will take you into a long running process, it will exit when you close the Terminal or terminate when you press Ctrl + C.

    In order to prevent this, we should run the application as a background service, by adding start into the command:

    forever restarts your application whenever it stops for whatever the reasons are. To limit the amount of times it restarts, use: -mX. 6 times for example:

  3. To list all running applications:

    You will find something like this:

    The number in the [] brackets is used for users (you) to take manual actions in forever.

  4. Stop a process by:

    is the process id we took from the #3.

  5. To restart a running application, goes:

  6. If you are developing some scripts, use -w for automatic restarts when the file changes:

Conclusion

Right now forever only supports Node.js applications. Maybe it will support other services like PHP or MySQL in the future, who knows?

But at this moment, we can tell that it can help keeping my & your Node.js server up and take away a lot of headaches.

Remove node_modules folder from your git repo

Today I pushed my project onto GitHub but yet forgot to add node_modules to .gitignore file. I am pretty sure that everybody has found themselves in such circumstances, at least once during his/ her developer’s life.

Today I’m going to note down the commands that help removing the node_modules or any other files/ folders that you mis-pushed.

First of all, add this line to your .gitignore:

Second, run your favorite Terminal and type these commands:

With these steps, you’ve now got rid of the annoying node_modules (or any other file/ folders) from your repo.

101 ways to revert to your old code using Git

Git is a powerful tool to manage your project’s codebase. Chances you have to revert/ restore commits to get rid of bad codes, or some bugs that you can not find out; these are some cases that you may find yourself in most often:

Stage 1. Coded but haven’t git added yet:

Stage 2. Added ‘by accident’, but haven’t commited yet:

Stage 3. Commited, but ‘luckily’ haven’t pushed yet:

Stage 4. Commited, pushed, “saddo”!

Pushed = somebody pulled and got that code. You could not just come there and say ‘Hey, delete your code you just pulled‘. Instead, you just say ‘I did the wrong thing, get this instead!‘.

The thing to do now is to push another commit, the content is the revert of current commit:

Conclusion

As you can see, git is an important and a powerful tool to work with that fastens your development and makes life easier.
