I have been part of an acquihire. As an early stage startup employee you work really hard for years, take salary cuts and hope that some day all the hard work will pay off. All of it will be for nothing if there isn't some kind of success/validation. In this case Digg was fairly well known but you don't get much credibility in the job market if the startup was never in the news. So if there is any form of acquisition, you get some of that brand exposure. In my case, even though we had built a great product, I rarely got inbound calls or interest in public forums. Now people reach out to me even when I haven't spent much time in the new company
India is one of Facebook's biggest market. I am interested to understand how will they compete against India's own open wallet platform, UPI, which is already very popular and already surpassed overall Credit card transactions in the country. Wallet companies like PayTM, PhonePe, Google Pay have a strong presence throughout the country and are dealing directly with fiat currency
The comparison of Ember to Rails is incorrect. Rails is a serve side rendered framework. Ember is completely client-side. Pick any client side framework and you will face the same diffculties or obstacles. Deep linking breaks if you are not loading depending models.
Every time there is any post on Ember, it starts a flame war. As @tomdale would say it, it was ember vs backbone, then ember vs angular and now ember vs react. In today's age of minimalism and extreme flexibility, Ember is very complex and huge - but that is actually it's strength. Build a massive app with just 2 people on the team and you will know why ember users swear by it.
