It depends very much on your current scope of influence. It can be hard to change a whole company, but easier to start with yourself and your team. Try doing one and see how it is received.
A previous CEO used to hold breakfasts once a month. It was really informal with a mix of people and a wide variety of work related topics got discussed. We could ask him things and he could ask us things. The setting made it really good for breaking down that communication barrier between juniors and The Boss.
In the town I grew up in (South Africa), there was a planning law that prevented the footprint of a house from being larger than a certain size. It had been that percentage for years and I'm hoping that it doesn't change because it's helped the area stay green and lovely without becoming overly built up.
Do similar planning laws exist in other countries?
There are two classes of payments - consumer and business.
This API is designed for business payments. Companies that process tens, if not hundreds of thousands of payments on a monthly basis. Think about the companies that sit behind businesses like Etsy or Uber - they need to take a lot of payments from customers and pay the supplier.
Many of those payment companies are financial institutions themselves who probably already have some kind of connection to programs like Visa.
I can also relate to the article because some hackathons that I have been to feel like you're building this thing that you know you are going to throw away. And events where you are able to use a new language you're under time pressure to just get it working rather than understand it. I'd rather spend a whole day on my own projects.
I've been to two other hackathons that are focused on attracting girls and women into the STEM arena (http://www.stemettes.org/events) but they don't exclude guys. The idea is more around splitting the participants into groups of different ability and helping them build something. I really enjoyed that the event is about learning/mentoring more than about wining prizes and I found it really rewarding to help kids that had some interest in coding.
The events are quite different from the 48 hour hacks because they are also catering for 6 year olds with short attention spans, but it felt like I was helping to show that coding is accessible to anyone of any age.
If you're a coder in London I highly recommend volunteering with them.
