Do you mind sharing how much data you are storing in Redis?

Not exactly. Me asking 1Q to 5 users results in 5Q being delivered to the respective users. Out of 5, and depending on the quality of the question, the level of activity of these users, generally results in 1 to 2 responses. Obviously the e

> Do you always have to operate expecting sudden spikes and that prevents you from moving to a cheaper hardware? In short, yes. This is inherent to the nature of Formspring – or to some extent social networks. Since most of your actions

The real benefits of AWS is scale on demand, if you need it. Formspring reached 1 million users in 45 days. How do you plan for this on typical hardware? Especially when you had no idea ANYONE would use your little side project? AWS isn't c

Those numbers are real – even a tiny bit lower than the real ones just because round numbers are easier to remember.

Direct questions hover around 1/1. Questions sent to followers, 5/1. It’s probably a higher engagement, albeit different, than Tumblr/Twitter/FB. When you ask a question on Twitter, how many of your followers respond? Very few. The nature o

Correction: generating revenue. Just not enough to cover the costs.

Why wouldn’t they? Many people have dedicated hours of their time to craft thoughtful and funny responses, I’d assume they would want to keep a record of this.

Yeah, you can check out everybody’s profile without signing up: http://www.formspring.me/pims and you can see every public thread. And until very recently, you could even ask questions without being a registered user to the users who had

You are apparently not the only one :-)

I can’t disclose the costs but I can share a few things: - Our cassandra and Redis clusters are/were the most expensive pieces of the architecture. - the PHP front-end wasn’t really efficient and required many `medium sized` instances. - Si

Call me when Quora has 30 million users ;-) But more seriously, the name Formspring originates from what Formspring used to be, and has been renamed Formstack: http://www.formstack.com .

@pinwale Starting March 31st, no new content will be created on Formspring. The site will be in read mode only. Ping me tim {at} formspring.me if you want more info.

We’re at 4+ billion responses. Obviously, many more questions were sent. If you were to guess 5Q/1R you wouldn’t be far.

While it’s heartbreaking to have to shut down something you’ve poured your heart into for many years, we have learned many things along the way that will help us for what’s coming next. Thanks for the kind words.

We `reset` the blog a few months ago. That’s why there are only a couple of posts.

We had a similar problem at http://www.formspring.me/ when we wanted to implement a search feature somehow similar to Facebook search. Our main application stack suffers from the same symptoms, robust, but slow-ish. After lots of thoughts

San Francisco, CA – Formspring 27M users, 4B responses, growing fast. Looking for Front-end, Software and Systems engineers. We’re having fun solving challenging problems. Buzzword dump: Cassandra, Riak, Kestrel, Thrift, AWS, mobile… We’re

It’s highly unlikely to happen, but I’d love to get an idea of how much it costs to run a big service like Pulse on App Engine. A monthly estimation would be great. Anyone mind sharing?

by iampims 15y ago
This is awesome. No need to run cron jobs to read from a text file and update data in Riak anymore. Imagine the possibilities of Hadoop + Riak for analytics applications/services. #MyDreamCameTrue

Native apps have push notifications. This is why Google released a Gmail app that is a just a UIWebView. Because there’s no way (yet) to have push notifications on a mobile website.

We use a solution similar to snowflake at Formspring: https://github.com/formspring/flake In the 18 months this system has been running, we never experienced any issue.

I find this truly amazing, not because of the technologies involved, but mostly because I find it fascinating that we can now easily process a library of over a million song and find which have a “slow build”.
