Today was the first full day at Whistler and it was packed full of activities. We woke up early, had a light breakfast and headed towards the RZR Tour.
I’ve never done any off roading before so I looked forward to the bumpy and dusty trails. The tour did not disappoint. I had a blast. The duration was not too short and not too long. I really enjoyed driving the RZR. The trail was thrilling but not dangerously so. Everything was tempered just right. The guide and the organization was super nice as well. During the tour, we caught some beautiful scenery of the Whistler area. I would highly recommend this, but make sure you are okay with driving the RZR though. If you are not fond of driving, then you should probably be a passenger instead.
The tour was extremely dusty, so we had to get back to the hotel for a quick shower and a quick lunch. Afterwards, we proceeded to take the Gondola from the Whistler Village to the top of the mountain. At first I thought the price of $58 CAD per adult was quite expensive, but let me tell you, it is worth every dollar and you should not let this amount deter you from having a wonderful experience at the peaks.
We really took advantage of the beautiful weather we had and took almost all the lifts that were opened to us as well as hiking many of trails up top. Instead of my bland words, I’ll let the pictures do the depicting.
Overall a fulfilling and tiring day. Really enjoyed it!
This week I received a promotional message on my iPhone from Rogers indicating that Rogers Ignite 500u is now available in my area. As of today, our household was using Rogers Ignite 250u. I called Rogers to have the upgrade, but a modem upgrade is required.
I did not really want to visit a Rogers Centre to pickup the modem, so the support person on the phone was very helpful and arranged to have a service person to make a house call to exchange the modem. The service person came on time and the modem was switched out without any issues.
I demanded that the modem be placed in bridge mode because I have my own firewall and WiFi routers. The service person told me that the Hitron CODA-4582 is a better WiFi router. I told him that I do not want a Rogers employee at their network operations centre to gain access to my internal and WiFi network. He was really accommodating and helpful but did not know how to place the new Hitron modem into bridge mode until I showed him this page.
He finally called it in and a person performed the configuration remotely. I also noticed the Hitron stored the WiFi admin password in clear text.
This means any one who is running a Hitron in non-bridge mode and is also functioning as your firewall, then any Rogers employee who is working in the network operations centre or their support team has access to your devices connected to your modem. Just beware! I’ve enlightened the service person to this exposure as well. He was a fine gentleman and I thanked him for his prompt service.
Now our house has higher speed Internet access with 500Mbps down and 20Mbps up!
In January of this year, I decided to purchase a Titanium bike and decided on the No. 22 Great Divide. I went from Aluminum to Carbon and thought I should give Titanium a try. The solid space age material has a long lasting appeal and the metal finish is super cool.
Yesterday it was finally ready, and we went to La Bicicletta to pick up my brand new road bike. Henry and Davide were excellent help from the store and together we customized the bike with:
SRAM Red eTap Shifters
SRAM Red front and rear brakes
SRAM Red DZero Power Meter
SRAM Red 50/34 crank set with 172.5 crank length
SRAM Red 11-28 cassette
3T cockpit with ARX II Team Stem
3T Ionic Seat Post with Prologo Saddle and TiroX rails
Reynolds Assault Wheelset
Continental Grand Prix 4000 S II 25mm tires
Chris King ThreadFit T47 bottom bracket and headset
Stock carbon forks from No. 22
Here she is:
My No.22 Great Divide with SRAM Red eTap
It was effortless to pair my old Garmin Edge 500 to the DZero power meter. I did have to 3D print an extra Garmin holder. I pulled the file from Thingiverse . It fit like a charm. Took it out for a test ride to make sure that all the gears are working and nothing is loose.
This morning, did a 49km ride with friends:
This is my first time riding with a compact gear ratio. There were many thing that I had to get use to, first the new eTap shifting; I came from Shimano Di2 shifting. The 50/34 ratio allowed me to stay on the big ring for the majority of the ride, but I had to get use to when to switch between the big and small rings up front. The new bike is about 0.5 lb heavier than my old Cervelo R5, but I did not notice the weight gain on the road this morning. When I made the decision to buy a Titanium bike I had some reservations. The biggest one was will it be more bumpy on pot-hole filled roads? The answer is not at all! I was very surprised how smooth the bike was on both bumpy and smooth roads. The power transfer was excellent when I stood up to power through some of the short hills this morning. My knees thanked me for the switch to compact gear ratios.
I am really grateful for the attention to detail and the service that I have received from Henry and Davide at La Bicicletta. Davide did a superb job in the bike fitting process, and the bike felt really natural this morning. I think the new dimensions work so well, that I’ll be copying them to my old R5. I would recommend any one to go there if they are seeking to purchase a bicycle for any purpose. They were super professional and friendly, and they delivered an excellent bike with a quality purchasing experience. Even if you have issues with bike fitting, they can help you out with that.
All in all I am super happy with my new mistress, and I’ll be riding her a lot this summer.
Today is another fun filled day with new found 3D printing experience. I printed more 3D things from www.thingiverse.com. The AA battery holder is a pretty good one. This print was actually in two parts and after printing, there was some assembly required. The two parts fitted perfectly, and now I have a AA battery dispenser. The picture shows the resulted print. It is a bit rough because I used the fast mode.
As luck would have it, the stars and planets came together and an end cap with one of our dining chairs cracked. It went from this:
to this:
This gave me an excellent opportunity to create my first 3D model for the very first time. No longer do I need to print someone else’s work. I spent the morning learning SketchUp, triple take the required measurements, and designed my custom end cap.
The one on the left is mine, and the one on the right is from Home Depot. I even added a little round ridge so that it is a better fit. Here is the result:
I purchased a 3D printer last week, and did not have an opportunity to open it until today!
I purchased the Wanhao Duplicator i3 Plus. It was super easy to install. After numerous YouTube videos on reviews of different printers and how to operate them,
I decided on this one. I didn’t want a DIY kit, so I settled for this preassembled one.
The YouTube videos really helped to prepare me to avoid the gotcha’s, and before long I was doing my first print, which was this Okay hand signal.
I wanted to test the printer with something more challenging. I opted for the Comura Articulatum from www.thingiverse.com. I found out about this object from the Maker’s Muse YouTube review of the 3D printer that I purchased. As you can see from the video below, the print was pretty successful and it came with articulating joints! I’ll be learning more about 3D modelling and printing this long weekend. Fun times ahead.
Last year, I built a NAS machine as referenced by my previous post here. This month, my media drive composed of an LVM logical volume of almost 5TB is almost filled.
This drive contains all purchased media and our home videos for Plex, as well as our time machine backups. To alleviate the storage shortage, I purchased two 4TB Western Digital WD40EFRX hard drives. This weekend I took the plunge and installed the two new drives into my NAS computer. In the spirit of the moment, without performing a backup, I proceeded to:
Use parted to partition the drives;
Use mdadm to create a RAID 1 device of the two drives;
Created a new LVM physical volume with the new RAID device;
Added the volume to the existing volume group;
Extend the logical volume to newly added 4TB;
and finally, Extend the ext4 file system to include the 4TB
In the end, I now have a near 9TB network drive that should last me for quite sometime.
In researching how to extend the logical volume, I also found out how I can upgrade my drives in my existing physical volumes to higher capacity drives without having to recopy everything to another drive first. This should come in handy in the future, because my NAS computer box has no more drive bays.
I know I probably should have taken a backup before this, but everything worked and I couldn’t be happier. Hurray, hurray, and hurray for software RAID.
On May 17th, 2017 a Mauritian Chinese newspaper, Hua Sheng Bao (华声报), published an article on how my maternal grandfather Wu Tao Xing (吳桃興), also known as Ng Thow Hing to all of my relatives, reminded us all how my grandfather participated in the formation of a mutually prosperous China – Mauritius diplomatic relationship that lasted until today.
I personally have known bits and pieces of the story, but this article apparently written by family members of my grandfather shed more depths to how he was instrumental to the founding of the Chinese Embassy in Mauritius.
It is too bad that the newspaper does not have a web site, at least none that I can find, but one of my cousins from Mauritius was kind enough to provide a photo of the original article which I’ve included here. Below the original I also provided a translation that my beloved wife was patient enough to do with me.
The original article:
Our translation:
This year marks the 45th anniversary of the establishment of formal diplomatic relationship between China and Mauritius. At the time when the agreement is still being established, this is a momentous event amongst the Chinese expat from Mauritius. A new generation of Mauritian Chinese are now among us, many of whom are not aware of such an occasion and how important it was to Mauritius. This story is worth retelling for those new generation.
In 1972 when the agreement is reached, Mr. Wu Huan Hing 吳桓興 (Gong Gong’s brother), Director of the Beijing Cancer Hospital, acted as the facilitator and arranged for the first Prime Minister of Mauritius, Sir Seewoosagur Ramgoolam, to come to China to discuss the possibility and development of diplomatic relationship between China and Mauritius. Mr. and Mrs. Ng Thow Hing 吳桃興 (Gong Gong and Po Po), and Mr. Wu Pan Hing 吳泮興 was part of the Mauritian delegation during the visit to China.
Once the relationship is established, the Chinese Premier Zhou Enlai 周恩來 promised to assist in the creation of the Mauritian airport, hospital, and subsidized in other infrastructure improvements. The success of this relationship continues today and China is still a prime benefactor for Mauritius. As a descendent of Mr. Ng Thow Hing 吳桃興, we are proud that this heritage is part of our family history.
Afterwards, when China wants to establish an Embassy in Mauritius, it was Mr. Ng Thow Hing 吳桃興 who acted as a consultant to assist in the Embassy location. Mr. Ng Thow Hing refused to accept any commission sighting his heartfelt connection to the motherland. Once the Embassy is completed, Mr. Ng Thow Hing 吳桃興 and his family members have always been invited — until his passing — to future Embassy celebrations in recognition for his contribution in the establishment of China – Mauritius relationship.
The son of Sir Seewoosagur Ramgoolam presented the CSK Medal to Mr. Ng Thow Hing 吳桃興 on the eve of the Mauritius Independence and Republic Day. A large part of Mauritius prosperity can be said, is owed to China’s assistance a direct result of the very same diplomatic relationship that Mr. Ng Thow Hing, 吳桃興 help to forge. All the key individuals mentioned in this article have passed away. As descendents of Mr. Ng Thow Hing, we will never forget how he was instrumental to the successful diplomatic relationship which both countries enjoy until today.
I believe the picture below is a photo of him sporting the CSK medal that was mentioned above.
I may not share his surname, but needless to say that I still feel quite proud to be within his lineage! I personally will not forget the deeds he played in Mauritian / Chinese history, and I will do my best to share this momentous event with my kids.
The post was from Roland Tsang Kwai Kew, he effectively provided some explanation and clarity on where the article that we based our translation may have been sourced from. Here is a related article from Le DefiMedia Group.
I really appreciated the fact that he attempted to get hold of me via Facebook. It is really good to find out that that someone out there is preserving, observing, and recording the Chinese Mauritian culture as well as the Sino-Mauritian connection.
Update: 2023-07-06
I did a search of my Granduncle (吳桓興) on Baidu (百度), and found this page. The page is filled with information about him, and a hospital in Beijing that is named after him, 北京市朝阳区桓兴肿瘤医院. Here is a link to their main web page on the Internet.
On a very selfish note, and probably the most egregious, name dropping action ever, I am pretty proud to have found a picture with my Granduncle (and his immediate family members), Grandaunt, Grandparents, my parents (and my sister), my aunt, and of course me back in the 1970’s when I was probably 3 or 4 years old.
I am in the front row, kneeling. My grandfather is wearing the hat, and my granduncle is to “his” right.
This morning I woke up to the news that an influential friend who I have the pleasure of working with since 1999 have passed away.
He was a passionate leader driven by a bottomless source of aggressive energy. He gave me an opportunity to excel in my work and taught me what credibility actually means and how to achieve it. Although on the surface, he would project a demeanour of all work and no play. Underlying that tough surface lays a big and caring heart. Those who are close to him will know exactly what I mean.
Aside from my family, Derek is one of the few colleagues who not only influenced and defined my work ethics but also contributed greatly to how I live and think. He encouraged and supported me during my episode with cancer. He is always there professionally and his support is as formidable, and as valuable as a diamond pillar.
I write this to celebrate the difference that he has made in me, and I am forever grateful for that. My condolences to the Smyth family. He will be missed and I will continue to take my cue from his spirit of life. That is eternal.
The last couple of posts, I talked about using a Raspberry Pi board to act as a WiFi switch to my garage door opener. I first used a Raspberry Pi 3 Model B, and then switched to a smaller form factor and more power efficient Pi Zero W.
I spent a lot of time writing security code on both the Pi Zero and iOS App so that the cipher and keys are in sync. I even threw in a time based HMAC algorithm so that the code being sent from the iOS App to the Pi Zero rotates every 30 seconds. The challenge here was the use of different languages and packages involved. I am using Node.js on the Pi Zero, so I had to get the crypto module from Node to work with the Apple’s <CommonCrypto/CommonCrypto.h> module in Swift. Since this is my first real Swift app, it took some time to sort things out. Why all the fuss with security? Because I only wanted certain devices (Phones and Watches that my family owns) to open my garage door.
I took the plunge to writing my first watchOS app. I thought it would be more convenient to open the garage door from the wrist instead of hunting for the iOS app on the phone and fiddle with the large screen.
After testing the stability of the WiFi on the device for over two weeks, I found the responsiveness to be pretty rock solid. Good job Raspberry Pi! I finally hooked it to my garage door opener, and long story short, I get to see the fruits of my labour. Check out the video below.
I am super happy with the outcome. I now have a remote garage door opener that will work anywhere in the world as long as I have WiFi. I don’t have an extra box lying around in the house that some suspicious third party manufacturer may have access to. This solution is totally private, secure, and power efficient!
Next step is to add a camera to the Pi so that I can actually monitor the garage door as it opens. The camera will be quite helpful if we have any drop off or pickups. I may even research how I can get Apple’s HomeKit connected to the unit.
On the software front, I still have to do some minor user interface clean up, and raise the security level another notch by using https.
Last weekend I spent my time configuring the Raspberry Pi 3 Model B to trigger a relay. Tonight, I finally took the time to solder the 2 x 20 pin headers to the Raspberry Pi Zero W board. I wired it all up again and took a photo with a quarter coin, so you can appreciate how small the circuit is.
I had to make a minor software adjustment, because the Node.js version that I installed on the Pi 3 did not work. Apparently I had to get the armv6l version instead of the arm7l.
After a quick re-install from the above link, I was back in business.
Now I’m going to test the stability of the WiFi on the Pi Zero, before I make the final security touches to the software and then to the garage door opener!
