ThingSpeak

May 01, 2018 by Tinni Choudhury in talks, meetup

Woohoo! I managed to attend my second consecutive IoT Brisbane Meetup! It helped that the meetup has moved to University of Queensland's iLabs. So I was able to easily drive there and park for free! I am glad I could make it because this month's talk was an intro to ThingSpeak by Daryl Ning from MathWorks. From there website:

“ThingSpeak™ is an IoT analytics platform service that allows you to aggregate, visualize and analyze live data streams in the cloud. ThingSpeak provides instant visualizations of data posted by your devices to ThingSpeak. With the ability to execute MATLAB® code in ThingSpeak you can perform online analysis and processing of the data as it comes in. ThingSpeak is often used for prototyping and proof of concept IoT systems that require analytics.”
— ThingSpeak

I am excited about this as I think I might finally be able to do something with my CPRO boards from Mbient Labs. I mean, I can't connect the CPRO board directly because the board doesn't have wifi onboard. But I was going to combine with a Raspberry Pi (or Banana or Orange) anyway. But given my recent foray into home automation, I am looking forward to putting ThingSpeak to use!

Kanban Pizza Game & Pizza!

March 30, 2018 by Tinni Choudhury in meetup

Last Wednesday of the month meant it was time for the monthly meetup of Women Who Code, Brisbane! This month there was pizza, I had the pumpkin and goat cheese pizza, and a pizza based game to explain the principles of Kanban.

My team for the night: Mama's Pizza

My team for the night: Mama's Pizza

The Kanban Pizza game was developed by Agile 42 and seems like a pretty effective way to learn Kanban principles. I joined three other coders to form Mama's Pizza while Cathie Hagen, a Lead Consultant at ThoughtWorks, hosted the games and taught us the basics of Kanban. I am happy to say that Mama's Pizza was able to produce many slices of delicious paper pizza but only after enacting Kanban principles.

During the first round, while we instinctively assigned each other set roles and had a rough flow, but we fell into the assembly line mentality of trying to make as many slides as possible. But the slides were too small, and our product owner rejected all three slides we managed to get out of the oven. But from round 2, as we learnt and applied Kanban principles, we were able to produce more slices and passed muster. It was fun and good time, but I also felt I learnt something. I don't always make the meetups for the Women Who Code group, but I am glad I made it to this month's meetup.

Lastly, before the game started, we got a few announcements for upcoming events. The one that caught my attention was the Internet Freedom Hackathon. Certainly a topical hackathon for the times we are living in and I'll certainly keep my eyes on this event.

IOT Meetup, Brisbane

Home Automation Hubs

March 29, 2018 by Tinni Choudhury in meetup

Like I mentioned in my previous post, on Monday, I visited the Arc Incubator for the Brisbane IoT Meetup.  The topic up for discussion this month was home automation hubs, and we got a comparison of Google Home Mini, Amazon Alexa and Apple's HomePod. It was an interesting compare and contrast presentation, and we had at least one attendees who asked the questions that I don't think home IoT industry has answered adequately answered. I.e. "How is this for? What are the benefits? Is it worth spending hundreds of thousands of dollars for mild convenience?" Not to mention, with the all the security and privacy stuff in the news, the question of "Are you worried your gadgets are spying on your or will be made to spy on you?" also came up.

The security and privacy questions are very complicated and, I feel, very personal and cultural. Also, what is private and what is not changes over time. I mean, not too long ago people would visit their corner store and said store would have stable enough staffing that with the regulars, the staff would be able to fill their orders as soon as they came in through the door. We lost this type of personalisation when we became one of the thousands of customers visiting the local supermarket. Now we are getting it back through loyalty programs and the likes. But we are more concerned about Woolworths knowing our preferences than we were Bob from Bob's Corner store knowing our preference. In reality, I don't think there is a big difference.

Indeed, I think we need to decouple Bokksu spamming until I give in and buy their boxes of hopefully delicious Japanese snacks from the more damaging misinformation and echo chamber effects. Of course, I could just be saying that to excuse my purchase of Bokksu!

As for my own experience with home automation hubs. I bought a Google Home Mini while they were on sale around Christmas. I bought it without thinking and purely because it was on sale. I have since bought a Philips Hue bridge and colour bulb. Also a TP-link smart plug. So my bedroom is now as automated as its going to get without needing to replace my fan and airconditioner. It's fun but mildly convenient, but I wouldn't say it's necessary for me. However, my mom whose having mobility issues due to her joint pain and my grandparents, who have severely limited mobility due to age and arthritis probably would benefit from home automation. That said, for them to get the maximum benefit, almost everything has to be automated. Plus there are more than a few items still missing from the elder care market for IoT to be truly useful.

Like a pill box that automatically sorts pills and ensures they are taken on time and regularly. Heck, my ideal pillbox would refill prescriptions automatically when pills become low and automatically schedule doctors appointments to get new prescriptions. Basically, a 24/7 home nurse! Of course, such a device would need the infrastructure in place. My mom would be able to benefit from such a device more readily than my grandparent. On account of my mom living in Brisbane while my grandparents now live in a regional town in Bangladesh. But infrastructure is always improving, especially in emerging markets. Indeed, IoT may well take off in South Asia well ahead of Europe. Just because of the cheap tech that's available in that region.

Talk on Reekoh

Reekoh

November 30, 2017 by Tinni Choudhury in ideas, meetup

I have been a member of IoT Brisbane Meetup for months now but I have not been able to get out of actually attend one of their sessions. This week finally, I dropped into their joint session with Mobile Monday to hear Dale Rankine speak about his experience with Reekoh.

It was interesting and insightful talk. It touched on the fact that some form the "things" that make up the Internet of Things has been around for decades now. However, the industry as a whole is still maturing with integration being an area that's lacking. Reekoh's platform addresses part of the issue, focusing on ingesting, storing and providing some analysis. But there is still room to expand.

It actually got me thinking about a platform for IoT but about you. There are a ton of wearables on a market that are designed to measure things about our body. But after the initial hyped died down, most of the wearable companies are suffering. Even Fitbit isn't doing as well as they maybe should be. So there might be potential to explore the possibility of bringing together a number of wearables to give a more holistic picture of overall health.  Indeed, looking at the whole picture and not just focusing on individual pieces like increasing activity or being more mindful. I think it is a concept worth exploring.

React Native

August 25, 2017 by Tinni Choudhury in upskilling, meetup

It's almost time for the monthly meet-up of the Women Who Code group. Last month was all about React Native. I enjoyed the intro and I am looking forward to this month's topic of "Hacking your career: tips and tricks for the job market".
