New York City, one of the last of the major cities that I had’t gone to. (Country capitals are not really counted because they are just boring administrative zones and cities of sheer population size doesn’t necessarily translate to interesting level.)

It’s so hard to find any photo that defines what NYC was like, it is so many things, and, the more you stay there, the more it is less about what you thought it would be.

So a typical google search for NYC would turn up the skyline, and the statue.

Lower Manhattan (click for larger)

We had our share of bright blue super sunny weather. In fact super hot. Getting around NY in tshirt and shorts just don’t feel right. Not quite a summer destination. Wow it was hot, for a Singaporean.

In a sense, these days with the Internet, photos, StreetView, everyone can see anything anytime, you don’t have to travel to know what something looks like. The point of going there is to live the city, ny style.

Which starts with their well-known, and currently half disastrous subway. It’s old, it’s noisy, cranky, confusing, doesn’t connect too well East to West, super lack of escalators and elevators, not the safest feeling with the homeless, and then there’s all the disruption and maintenance works.

But you get used to it, up the stairs, down the stairs, through the cranky dumb heavy turnstiles, magnetic swipe card, directions Uptown Downtown, nearest lines, exits NE SE NW SW. NY really lives and breathes by its subway, more so than many or almost any other city. The gridlocked roads and traffic are plain terrible, the parking is terrible (what kinda nonsense is $30/hr), the buses are terrible, hence the only reasonable way to travel around is via the subway. Which makes it wonderful, the city is built around and lives around the subway, you have dense neighbourhoods that are within close walking distance to multiple stations, you have lots of food, services, attractions, etc, all near stations. Even tourist attractions are easily accessible without requiring taxis. That’s in huge contrast to cities that don’t have an extensive subway, you’ll see huge distances to walk, huge parking areas etc. I love NYC for this. Same for Paris, London. Singapore still needs way more stops at closer intervals.

Next, the Times Square. I mean I knew we were going to stay near to it, I thought that was a superb idea in terms of convenience, I didn’t know what we were getting into. omfg we weren’t like in the middle, we were like one traffic junction away at between 7th and 8th Ave, but damn it was overcrowded with tourists, buses, traffic, homeless people, and probably the worst pithole city area of the entire USA. I don’t think any other city in US has this amount of density. So yes it’s a little too close, for most people. I live in a fairly crowded city, I am pretty comfortable with crowds, and I am fine with it, but I can imagine how this would be a disaster for most people I know. Also frankly Times Square is just an hotpot of subway lines, office buildings, same old big name mid market clothing stores, same name restaurants, and the slew of theatres that settled in. Basically it’s not like the peak of artform or anything.

Times Square


Next up, theatres and Broadway. How nice of them to experience a surge in popularity in recent years, with soaring ticket prices, packed houses, and tons of shows opening. There’s really alot of shows, maybe more than London when I last was in London 10 years back. It’s crazy the crowds. Musicals are great, but it’s just one facet of life. Anyway I feel like there’s no real musical streets around here, it’s kinda dispersed and swallowed up by the Times Square kitsch crowd of tourists and blinky lights, so it doesn’t feel like the area is theatre-y or artsy in some form. Yeah they need to just close the streets to lousy traffic and have more of a feel. I think West End is a bit better in that way, not so stupid feeling. But there are more shows here.


NYC food

The food. The varied population gives rise to a huge range of tastes, from the american trash like sugar-laden donuts and iced coffee, to the fine dining, to the abundance of mexican, chinese, jewish, italian, etc. It’s great. It means you get to change around and eat different things everyday that isn’t terribly-ugly looking burgers and pancakes. Here are some pizzas, in the new york slice style. Big, flat, on a paper plate, hanging over the edge, hot and tasty. Eating this over the long run will no doubt make you fat and nutritionally unbalanced, as with most american cuisine, but it’s fun, and inexpensive relatively. I guess you could do dollar slices all day, but I suggest trying some others too. Joe’s Pizza here isn’t too bad. NY Pizza Suprema near to Penn Station is awesome as dine-in place, saw this featured in a YouTube video and it was a good recommendation. I really enjoyed both.

Bagel and cream cheese. Because I’ve never seen shops full of 50 different flavors of cream cheese, 10 different bagels, and much tastier than those ridiculous breakfast cafes. So yeah come have some. Brooklyn Bagel & Coffee is awesome, Pick-A-Bagel chain is more common, less awesome, but they have like hot breakfast stuff for cheap.

Food Truck

Food trucks. Really quite the NYC phenomenon, they are everywhere. Never really went after the famous ones. Nathan’s Hot Dogs are everywhere, I’m not impressed. Dinge’s Waffles have a few spots, but I didn’t want sweet nonsense. There’s a ton of the meat stuff like lamb on rice, etc etc. Seems good. Really they are just slightly more neat looking versions of street hawker stalls in Asian countries. A thing, but not a cuisine mind you. I think it touches their American dream thing – being able to rent/buy one on the cheap and just set up shop anywhere and make some money.

Churros Ice Cream Sandwich

Smorgasburg a weekend food market in hipster corner Williamsburg, Brooklyn. It’s so popular it’s apparently expanded onto Manhattan, which makes it so much more convenient because you don’t have to like trek all the way to this corner. Anyway it was wonderful. Very hipster, as you can see from my churros salted caramel ice cream sandwich with oreo powder. Yeah. Also lots of other fancy stuff that you don’t see in Asia, like Asian food made hipster, like African stuff, like ridiculous combinations.

Chelsea Market
Los Tacos

Chelsea Market and Los Tacos. Another hipster area. I don’t know whether it’s overly touristy, but the locals still like the place, so I guess kudos for staying in scope, same for Smorgasburg. I guess the real tourist are just stuck in Times Square. Or maybe the tour buses herd them outta this expensive city as soon as possible. So Chelsea Market, tacos and lobster are great, the rest are probably all good, but just not as superb value.

look at the sauerkraut
so old school

Finally Katz’s Delicatessen. I guess every single guide talks about this place, because it’s been around for so damn long. You can’t come here too often, you’ll die from the mountain of meat they try to serve you, but I really liked the Reuben Sandwich, and I really didn’t like the signature roast beef sandwich, because the roast beef is so weird. Hot dog was great, pickles were too huge, serving sizes were too huge, atmosphere was superbly comfortable and homey. Place was featured in the movie When Harry Met Sally, very very very good movie, go watch it. Anyway I would totally come back here a few more times, but I had too many things to try and too many places to go.

Shake Shack

Ok so you have to eat a burger I guess. You can go to Shake Shack, I love it, it’s great. It’s quite like er it’s just a fast food burger place? Yeah exactly, I don’t know why it takes a fast food burger place to give me a no-tipping required, decent service, pretty looking burger. Coming from Asia, burgers are neat and well prepared things when you eat out, even if you go to McDonald’s, Mos Burger, or a $20 cafe, the burger looks presentable. In US, so far I see alot of normal american cafes with burgers that are not presentable. How difficult is this? Apparently very, hence the locals like Shake Shack alot. Also apparently Five Guys, but I didn’t go because the exterior looked lame, but people keep praising it. If you can make an average idealistic image of a burger, you win, in the US.

One of my favorite meals and things to do, is to just sit in the park at lunch time and eat a sandwich or some takeaway food. I think that’s one of my favorite moments in European and western hemisphere cities. It’s just so nice, in the right weather. Go to Bryant Park, it’s super convenient outside a subway stop, it is surrounded by bakeries and shops, and you can buy from Whole Foods as well. It’s got the right amount of green space, park chairs etc. Union Square isn’t so good, and many of the other spaces are too small. Bryant Park is nice. Also beautiful NY Public Library in the back, go in and take a look.

Here’s hoping you get to enjoy your America trip and not hate the living lights out of that place, which isn’t difficult to end up doing.

Google Cloud Architect

Received my Google GSuite Administrator and, more importantly, Google Cloud Architect certification in Aug. =)

Spent alot of time reading the docs and going through Coursera lessons, plus all the hands-on experience over the past 3/4 of a year really helped a lot.

Cloud Architect is geared toward use of Google Cloud Platform, focusing on almost all aspects of the networking, compute, machine learning, data management, identity, security, solutions design etc. It’s a super alot of information and products that are covered.

Gsuite is much simpler and covers setting up and managing a Gsuite domain, quite a lot of details but far less.

There were very few resources on Cloud Architect to go on. Here are some tips and areas to focus on:

  1. Make sure you have hands-on experience in setting up basic networks, VMs, resources. As much hands-on experience as possible. It will be super useful in having a feel of where things go and what workload or design is appropriate. You could do this before or after reading the docs and taking classes.
  2. Official docs at   Read through all the intros, docs, FAQs. There’s alot of good and updated information inside here. It’s quite lengthy and dry so you might want to do this back and forth with all other resources.
  3. Official study guide and case studies at  The case studies are used in the actual exams and they might introduce more, who knows. So you should just read through and familiarize yourself beforehand as much as possible. Think about what you might design. You don’t need to memorize anything here.
  4. Coursera courses are recommended, and designed by Google official trainer. This set is pretty good. You can just listen through the videos, try the guided tutorials which have good hands-on experience in most aspects. You can get through all four courses within a month very quickly. If you have extra time, you can also try the single course designed for AWS professionals, it has a slightly different perspective which is nice.
  5. I believe there is a new linuxacademy course but I didn’t try that.
  6. In-person courses weren’t really necessary, I didn’t have access and it was too expensive.
  7. Cloud Next Youtube videos are quite informative. But there are too many to finish. Worth a listen as they have nice real-life scenarios with real clients. Good tips in many areas.
  8. Knowing how to choose the appropriate storage tier, the appropriate monitoring tools, compute tools, networking tools, data management tools are totally essential and expected.
  9. Knowing how to debug certain errors or issues are good to know as well. Unfortunately this is hard to come by in lesson or tutorial which is why I strongly encourage hands-on experimentation or real-life use if possible. Although this might be tough to expect.
  10. Note that the exam was largely design at the start of 2017, same for the Courses, whereas online documentation is up-to-date and evolving every single week. GCP launches new products, new changes, updates, new price discounts like all the time. It’s a very fast paced platform, so some difference might be there. However don’t worry too much most of the concepts stay the same. Of course you can expect the newest latest tool will probably not be into the exam yet.

Good luck and have fun getting into GCP. It’s gonna be useful and informative even if you’ve a regular GCP user as the platform is so wide in scope.

Ruby on Rails on Google App Engine

and the impossible number of problems that one runs into whenever trying to do anything code related.

Testing: Ruby on Rails 5.1.2 application to run on Google App Engine Flexible environment.

I wonder if running Ruby-2.4.1 on laptop vs the Ruby 2.3.3 on GAE will cause a problem….nvm.

Apparently GAE Flex can now run other languages by managing it inside a docker container behind that scenes. Well lo and behold, we would no longer need to set up Compute Engine, Container Engine and the likes. Let’s see how well this could possibly work as the community document is rather scarce, and the official docs are pretty lame by running a sample Rails app within gcloud cloud console instead of deploying a real-life app from desktop.


  1. First problem, production env key. Stupid Rails keeps doing this.
  2. GAE requires a /_ah/health check. Why can’t they be more upfront about this instead of failing stupidly in the background
  3. Realised the repeatedly deploying adds more versions into GAE, oh it doesn’t replace each other. I’m such a GAE noob.
  4. GAE version cannot be deleted unless it’s not serving. Oh. Then why make me wait so long to throw an error. Dumb GAE
  5. So many errors upon trying to stop/delete versions. Dumb GAE
  6. Need to add a controller and roots. Dumb me

Oh look it’s running finally


and also managed to route the domain too. Okay.

Change in the big world


I wonder if people look at the world, feel that it’s too big, too problematic, too complicated, too difficult to change, and just decide to turn away / run away from it all.

When you realise that there are 6 billion+ living beings, and counting, and increasing faster than dying, when you realise that there are so many countries, so many ‘races’, so many religions, so many square kilometres, that you can’t even properly visit all the countries once in your lifetime, that you in your lifetime only know, interact and remember so few of them, when you realise how short your life and time is, that is when most people will just drop fancy ideas from their head and instead just grab that burger, take that commute home, watch some TV and settle in for yet another night, yet another weekend, yet another year end, yet another new year.

Indeed our little human lives are all too often so short. 24 Earth hours, 365.25 Earth days, 100 Sol years. And indeed most people do not end up making a huge change in the world during their lives, commonfolk aren’t heroes, generals, leaders, presidents, big bosses (of big companies), celebrities, etc. Heck even these people don’t always get to make significant long term lasting changes.

That’s probably why it’s so easy for us to turn away from it, to be sucked into being a part of the ecosystem, to run away into fantasy and movies and tv shows, and make-belief sports competitions, and self meditation.

But there’s always some people who feel that they could try to change something. Probably they never thought it would get so big, but it did, and it grew and grew. Change happens. Fortuitously, accidentally, decidedly?, endlessly.

The odd thing is that if you look back, you see all these massive changes happening, despite sometimes everything feeling that it might never change at all, being so set in stone and all.

The grand nations, the grand corporations, employing tens of thousands, hundreds of thousands of staff, seem like too big to fail, too old to fail, and to have been around ever all the while in our lives. But they weren’t, and they’ve come, gone, changed, disappeared, so many times within years or decades.

When I get old, perhaps I will look back to the time as having lived through the Age where there was widespread Internet version x, where Apple and Google grew big (might be bigger or smaller in the fuure), where SpaceX and Tesla appeared from nothing, where Netscape Navigator was a thing, where people first learned programming (not really it started before my time), and so forth. It never really felt like anything, but when we look back, it might just be. What did it feel like to live through the rock & roll? When Bob Dylan was alive? When x celebrity was alive? When JFK was President? When Trump was President? And all I could say was it just felt like the one life I was living, no different than any other possible life I was living, which is no other. It was as good as I could have, as bad as I could have.

I think it is good to have people who dare to change, to dream, and be different. Not to try to be different or special, but because they see that some things could be better. It would be a tad sad to just accept everything at face value as the way it will always be.

In a way it’s like a parallel of the chaos theory (which is frankly quite a simple theory but hey it opened people’s minds).

There was an article today about the definition of “Space” – what is space? Yes, mostly the outside of Earth, Space. It made for some interesting thoughts on how weirdly we define that word and how we understand it so counter-intuitively and in a conflicted manner.  The absurdity of it all, really. I’m surprised human brains don’t implode or remark at our own stupidity and narrow view of the universe/physics.

Which brings me to the supposed 4D / multi dimensional / multi whatever space of the Culture science fiction novel series by Ian M. Banks. The “Level 8” tech space ships travel and function in realms beyond our description and imagination, not that the book tries to dumb it down but rather knows it cannot explain it at all. As fictional as it is, it could well be an approximation of the truth. All this fancy futuristic stuff. I’m a bit sad I will not get to experience it. Cryo preservation is not ready, nor is it useful. Why in the world spend so much money, energy and resources to preserve someone when it is more useful to grow a new human who can learn new stuff and be more useful. It was worked for eons and might work for millenia to come.

One weird trip to HK

It was quite an unconventional trip to HK.

nice hotel


Rainy weather and sick person

Lunch with local friends

But I just can’t avoid good old Mongkok

Didn’t manage to take their iconic mini-buses this time actually

but I love the crowd

and many views from the streets, from above, from below

dang, using the pansonic 20mm f1.7 II does have quite a fascinating color saturation and perspective. cool.

One weird trip to HK

Not HotDog

A most hilarious example of a applied machine learning AI tensorflow app running on Android/iOS. Very well designed concept, and very entertaining element of the Silicon Valley show too. Awesome.

Can’t wait for more AI/ML to get into phones.

Year 2017 phones should not be about screensize (dumb), battery size (dumb), fingerprint sensors (dumb), camera quality, number of camera sensors, how much ram, headphone jack, OS version (all dumb), it should be about whether it comes with a built-in AI/ML acceleration chip and how actually smart-phone it is.

Then again, it’s so in its infancy that any AI chip created in 2017 is going to be superseded in 2018, and super-superseded in 2019 in ways we cannot even imagine right now. Still, it gives us something to look forward to in the next generation of phones. Other than better screens, better batteries and better cameras.

Hong Kong to Shenzhen

After a few trips to HK, it was time to see something new, ie a day trip to neighbouring Shenzhen to visit Huaqiangbei electronics market and Dongmen Pedestrian Street.

How to get from HK to Shenzhen via train

a. From within HK, get to the East Rail Line. it’s the light blue line that runs vertically upwards. From Causeway Bay you can take a bus across the tunnel to Hung Hom Station.

If you’re on the other side, you can take the green line to the interchange at Kowloon Tong. It’s a long journey ~>30mins, so take a seat and enjoy the scenery.

When boarding the train, watch out for the ending station. There are two, either Lo Hu Station or Lok Ma Chau station. Both stations have a border entry, but I went to Lo Hu as it is closer to the places we are heading to. Make sure your Octopus card has sufficient value as this long ride cost more than the usual downtown trips. I think it was probably 30-40 HKD in total.

East Rail Line is a longer and bigger rail train than the usual MTR.

b. HK Customs

Since you are leaving HK, you’ll need to go out of HK customs. Alight from the train at Lo Hu station, follow the escalators and signs and customs is right upstairs.

c. China Customs

You’ll walk like 100m and then it’ll be the China entry customs. If you need a visa, you should be able to apply for one upstairs. I didn’t need one as Singaporeans get visa-waiver for trips less than 15 days.

Customs was a pretty straightforward process.

d. Enter

Right out of China customs.

Once you step out, you’re right at the entrance of the escalators down to Shenzhen subway green line Louhu Station in the basement, and on the right is the Lohu Commercial City mall. Apparently you can start shopping right there but we heard their prices are so good so we didn’t bother and instead took the subway to Dongmen.

Louhu Commercial City on the right
Luohu Subway Station
The one way tickets. Tap using the chips to enter, drop it into the slots to exit the station.
Buying tickets at the machines. There’s also English mode available. You’ll likely need coins or 5 yuan notes.

e. Dongmen

Pedestrian Street. Large McDonalds there is a good landmark to remember.

Dongmen Pedestrian Street is two stops away. Buy your subway ticket indicating start at Louhu and end at Laojie Station. Cost = 2 yuan for one way ticket.

Once you exit from Laojie Station, you’ll be right at the shops. I suggest you get out to the ground level to get some bearings on where you are. There are many many exits for the station but most exits are fine. Use Exit F if you need to choose one.

It’s a very large area with tens of buildings so enjoy walking around.

f. Huaqiangbei

I went to Huaqiangbei as well. Same, use the green subway line 1 for another 5 stops or so. Cost is still another 2 yuan.

You can go into the all the buildings left and right of the pedestrian street, between the stations Huaqiang Road and Huaqiangbei.

Electronics all over.

Good luck looking for what you want.



Ease of travel: Good. It was convenient, just follow the subway lines and signs, no complicated routing or taxi necessary. Cheap journey as well. Both subway have languages and announcements in multiple languages including English.

Safety: Generally we felt pretty safe. Minimal beggars / touts. Overall service was pretty decent and good. Just be a normal level of mindfulness as per usual travel and you’ll be ok.

Note that Google Maps in China is either restricted or lacking in info. You might want to arm yourself with Baidu Maps before getting in. Baidu has more precise location and information, but it’s all in Chinese.

Currency: You’ll need to use local Renminbi. We didn’t try with HKD. Even if you succeed, you won’t get as good a bargain. There’s plenty to shop – clothes, bags and shoes.

Pretty bustling at night when the crowds come out.



There are also tours etc that can bring you into Shenzhen, if that’s your thing. But a one-day solo trip is definitely doable.

Hong Kong to Shenzhen


“It’s dark because you are trying too hard.
Lightly child, lightly. Learn to do everything lightly.
Yes, feel lightly even though you’re feeling deeply.
Just lightly let things happen and lightly cope with them.

I was so preposterously serious in those days, such a humorless little prig.
Lightly, lightly – it’s the best advice ever given me.

So throw away your baggage and go forward.
There are quicksands all about you, sucking at your feet,
trying to suck you down into fear and self-pity and despair.
That’s why you must walk so lightly.
Lightly my darling,
on tiptoes and no luggage,
not even a sponge bag,
completely unencumbered.”

– Island, Aldous Huxley
