I have been thinking of doing a project in wearable electronics. Adding lights that blink on a skirt when I move seemed a good one to start. I had a white skirt lying in my cupboard. I got a Flora board, one Accelerometer/Compass Sensor and some LED Sequins from Adafruit. There are a few distributors of Adafruit in India. I got all of my stuffs required for this project from ProtoCentral. I also got conductible thread, a 3.7V Lithium Ion battery and a Adafruit Lipo charger to charge the battery from any USB port.
Before any stitching, I tested the board and the Accelerometer using jumper wires and a breadboard. I got an initial version of the code working too where the Accelerometer was sending the x, y and z values on the Serial Monitor in the Arduino IDE.
I stitched my circuit on the inner lining of the skirt. Here’s how the circuit looks.
Here’s the github link to the code that I uploaded on the board. I took the code mentioned on the Adafruit’s Sparkle Skirt manual, but I had to make some changes since I was using LED Sequins instead of Neo-Pixels. LED Sequins are much cheaper than the Neo-Pixels and I didn’t need the brightness and functionalities of Neo-Pixels. Also I adjusted the delay values and the move threshold values to make my circuit work.
And, after a long spell of procrastination and some more procrastination, I made the initial version. Need to add more sequins to this to make the lights more visible. Here’s how the initial version looks like.
Some learnings which are scattered in many videos and blogs on the adafruit website
1. You can not put more than 5 Sequins in parallel on a single Flora pin.
2. But if you use Neo-Pixels, you can put as many because they are chainable.
3. For 1 to 5 New-Pixels, use 2 Ply Stainless conductive thread. For more than 5 Neo-Pixels, use 3 Ply Stainless conductive thread. For more than 20, you should use silicone covered wire.
I have been a silent and pretty much a passive follower of Technically Speaking since the time they started. If you are wondering what’s that – it’s an email digest to help and inspire people to speak at technical conferences. You can either sign up or follow them on Twitter.
Lately I realized that I actually like public speaking and sharing knowledge after I spoke at a couple of training sessions at my office. I have been thinking of giving public speaking a shot since then, but always got stuck at the questions of –
What? How? and Where?
The recent digest from Cate and Chiu Ki nudged me a little to do something about it. It looks like a perfect opportunity for me to set my first public speaking goal and there’s not many of them. Here it is –
Yes! It was as easy was that! Although it took me one year to think and ponder upon the idea of creating a website, when I got down to writing one it took me one Sunday evening to create a static website as a birthday present for my husband. Here’s the link – http://kakkeshwar.net/
I used bootstrap as is eminently visible from the page. And CodeAcademy helped with me a crash course on basics of html and css.
I attended womENcourage2015 at Uppsala University last month. First, I thank Google for supporting me to attend this conference. It’s a wonderful program by Google where they give women in STEM grants for attending technical conferences. Those who wish to apply please visit this link.
The conference started with a Hackathon organized by Intel and Microsoft. It was my first Hackathon at prototyping with micro-controllers. I had an idea of making a smart accessibility device. A few people became interested in my idea and we modified the plan a little bit. Our team won the third prize at the Hackathon. It got some publicity at a local Swedish daily too!
The main conference was held in the main university campus. Many sessions took place at the magnificent main hall of which you see the picture above. The conference was attended by women from many countries, most of them studying in Europe.
Here is a list of some of the sessions I found very interesting
1. “On Grit and Being a Token Figure” by Åsa Cajander. Do watch it from 16:20 of the video of day two
2. Computing for Humans by Vicki Hanson
3. Panel discussion on Out of the Ordinary Jobs After a CS Degree
Overall, it was a very nice experience to see so many women studying, researching and working in the field of Computing. It was a great experience learning from them and knowing about them a little more.
Around June 2014, I started organizing technical talks at my office. The organization I work for is not small and we do have a technical council that organizes trainings and an annual coding competition. The quality of many of the trainings are good. I personally did a series of trainings on advanced algorithms and data structures by Dr. Naveen Garg and it was very very good.
But, I realized we were missing something. The trainings planned by a central team was top-down. It should also be supplemented with bottom-up employee driven informal trainings and technical talks. We write verification tools for the semiconductor industries. Domain knowledge is a very important part of our job. But we essentially build software. If the foundation of software is weak, then in my opinion, even a brilliant domain specific idea can not produce a better product which can be reliably used by our customers. And towards that goal, I thought we should organize more informal tech-talks.
I approached my manager and his manager and both of them were interested. I started off with a video screening of “Insecure coding in C and C++” by Olve Maudal. I thought it would be a super hit since I loved watching it. But it was not! People preferred a more interactive technical session.
So far, in the last six months I organized 5 tech-talks which is far less than what I thought I would do. But I am glad that I got at least 4 people agreeing to present on different topics. What I learned from organizing the tech-talks are –
1. Organizing them on your own takes a little effort but it is definitely a good experience.
2. A technical talk should not exceed 1 hour. People do not have more than one hour to spend on a topic which may not align with their work. And there should be at least 15 minutes of discussion.
3. A technical talk should never happen on Friday post-lunch as people tend to leave early on that day.
4. A technical talk should not focus only on the domain in which we work, but also on other domains too. We had a technical talk on “k-means based document clustering” and it gave us a few ideas which can be applied to our work.
I had thought of creating a platform for women working in the IT industry in India to network with each other when I started WFS-India. But that group was purely aimed at encouraging more women to start using and contributing to FLOSS. Attending both GHC and Adacamp made me convinced how important it is for women in tech to connect with and motivate each other.
Articles like this are proofs that we need such groups. If you happen to read this post and are a person who identifies as a woman please feel free to join the group if you are on the Facebook.
I am so so glad that I attended Adacamp, Bangalore last month. First, it was nice to be able to talk freely in an environment where everyone agrees to the basic principles of Feminism. It was a liberating experience because I did not have to think if I am alienating the person (mostly men and sometimes women too) I am talking to. I didn’t have to worry about if I was making myself and whatever I had been doing and talking unacceptable to the person.
I realized a few more things about myself. That I love helping others. And it gave me immense joy to be able to do that. That students were coming up to me and asking me about OPW or WFS-India was wonderful. That I got to encourage them in pursuing what they wish to pursue and sharing opportunities with them and thus in a way mentoring them made me glad.
I learned that the sexism that women face at workplaces can be dealt methodically. These life skills can be learned and practiced to help ourselves get less affected emotionally.
I also learned to be sensitive and respectful towards the choices and preferences that others have. I might not believe in them or follow them, but it’s important to understand them and interact with the person accordingly so that I do not hurt the person or make him/her uncomfortable.
And finally, it was lovely to meet wonderful ladies from different places. Got to connect with them. Learned a lot from various sessions. Unconferences are cool way to learn the things that we the participants decide to learn. Got new ideas to work on them. Hopefully come February, I’ll be able to start on some of them. I do hope to attend it next year as well!
There are 2 types of people I have seen in the software industry. One who just wants to hold on to his/her whatever job he/she has got, doesn’t want to learn new things, doesn’t want to try new things and definitely doesn’t want to take any initiative. And there’s another type – and I must say that I met very few of this type – who are passionate about their work. They drive new things. They bring new ideas and execute them. And I must also confess that before coming to this conference, I haven’t met any such women in the IT industry. I am not counting the women in FLOSS community. They are passionate about technology and open source software but I do not get to see them in the IT industry. GHC India 2014 surprised me. I got to see women, who are passionate about their work, talking on various technical topics that includes machine learning, cyber threats, secure cloud, tends in hardware. These are women who are mothers, wives and they are at senior positions at big multinational companies or have started their own startups.
They are passionate about their work and technology. And it filled my heart with hope. I won’t say that I was clueless or pessimistic about my future, but seeing women entrepreneurs or women at senior positions working in challenging and interesting fields did motivate me to believe in myself and work hard on what I want to achieve.
So my message to all the women in technology, if you are passionate about your work, if you wish to achieve something in your life, then do attend it next year. It will definitely going to be an awesome experience attending GHC.
It’s one thing to know that you will see more than thousand women in computing in one place and it’s completely another thing when you actually see technical women all around you talking, laughing, networking with each other at the conference venue.
The day 2 of the Grace Hopper Celebration of Women in Computing in India started with a bang. The huge Kalinga hall at the Hotel Lalit Ashok was jam packed with women from different cities in India and abroad.
Jayshree Ullal, the President and CEO of Arista Networks gave an inspiring keynote. “Be passionate about what you work”, “Take risk, follow your instinct” were some of her key messages. I do suggest you watch her keynote here.
There were so many sessions going on in parallel that I wanted attend, that I really had a tough time in selecting where to go. The session on Wearable Technology was nice. Also the session on “Technology Trends – Hardware and Software” was informative.
Networking and bonding are very important part of GHC. Everyone of us were encouraged from the very beginning to connect to women working in other software companies. There were booths established by various companies offering quiz and goodies and collecting contact details if any one is interested to explore opportunities. And oh! the food was awesome too!
It’s super exciting to attend Grace Hopper Conference India 2014.
The first day had 2 parallel day-long events – a hackathon and a bootcamp on Ruby on Rails. Since I didn’t pre-register for the hackahon, I attended the Bootcamp during the first half and some time in the second half. But most of the second half I sat through the Hackathon presentations! And they were amazing. Women from Hyderabad, Pune and Bangalore teamed up and built amazing stuff over a period of 2 months. There were students and as well as working professionals who took time out of their professional and personal commitments and worked on their ideas to create a product with value to the society.
One of them was a mobile app which connects people who have stuffs which they want to give away with the people who needs that stuff and there’s no money involved in the transaction. Coincidentally, a few days back a friend was looking for just the same thing after he faced the problem of loads of not-being-used-anymore stuffs that he had bought for his baby.
Then there was another app which converted voice to sign languages which can be used to communicate with a differently abled people. Another app made it easy to lodge complaints related to civic amenities and that complaint gets registered to the BBMP website. It was amazing to learn about every one of the presentations!
The presenters at the bootcamp were good too. And Ruby on Rails being a framework where you can actually make your app online in just a couple of minutes it was a good choice. But there were a few technical glitches. But I think it was good enough to invoke interest among those who wish to implement their ideas quickly or pursue learning more about Rails framework.
