EC2 Spot instances

Posted on December 14, 2009

The thing I really like about Amazon’s cloud stuff is they’re constantly undermining themselves with new innovations – spot instances are another great example. Taking the utility metaphor a step further you can now rent their services when nobody else is for cheaper, like buying electricity at night.

A lot of the tasks I’m envisioning for Sproozi aren’t really time dependent. While it’s important to show you a page in a timely manner, crawl and index a brand new website you add quickly and basically be interactive there is also a lot I have to do in the background. The huge and growing list of URLs people add all need to be re-crawled and re-indexed regularly is just one of many examples of processing vast amounts of data. These tasks are always running, always in the background.

Spot instances are a perfect fit – I can bid the price I want on extra capacity spin up some extra instances to join the cluster when they’re cheap. Over the next few weeks I’ll probably try to add some spot instances to my Hadoop dev cluster and see what happens.

Signups via twitter API

Posted on December 7, 2009

This is possibly big news, something I’ve hoped they would do for a long time and something Fred Wilson voiced his support for a few weeks ago: Creating user accounts via the twitter API.

Both the projects I’m working on full time could benefit from this. Sproozi of course because we could create user accounts for them and help users find interesting local people to follow. My oft promised side project which at it’s most basic level [the one I'll launch first] aims to make making announcements easier could benefit by making the signup process seamless – users wouldn’t have to already have to have a twitter account, they could create it all in one step with us.

That I think is what makes this such big news, sites that rely on users already having a twitter account to do something useful will be able to create that account as a seamless on site process. That will help drive users to the sites and drive users to twitter. Let’s hope they start rolling it out to other developers!

There’s no money in it

Posted on December 5, 2009

I followed up with a few potential investors who’ve had my pitch for Sproozi today. It’s been a week or two since I heard from them and I honestly wasn’t surprised when they came back with a no. Not hearing anything doesn’t exactly show a great deal of excitement.

I’m an optimist though and on the bright side I haven’t had a conversation or a meeting that I haven’t benefited from.

With first VC I met I had a pretty friendly audience, I knew him already, and I got some really good advice about how aspects of the pitch, the business in general and some introductions. With another, less friendly, it was clear I hadn’t done my homework. In yet another I learned a bit more and took on board the suggestion that I get a core set of users together to beta test the project – that basically just launching it blind was probably not going to go anywhere.

The rest of my meetings and conversations have been just as good. In each one I’ve refined my pitch further had clearer and better prepared answers for questions but I think I may be making one mistake that is keeping me from getting funded- trying to0 soon.

I’m starting to think that, because I have to explain the idea. I really s to be able to just give someone a link they can click and play with. With a link and 10 minutes, countless objections can be overcome and services that sound similar dismissed – it also gives a pretty clear idea of exactly what the thing does. I can’t possibly manage that level of understanding in any pitch, no matter how long or how refined.

So what’s next? I’ve got a side project I keep hinting about that’s painfully close to ready to launch very soon and then I’m going to keep working on Sproozi, get it to the point where I can send that link, develop some feedback from users and get some interesting data – get it to the point where I’m talking about what we are doing, not what we want to do. I’m not put off, if anything I’m more focused on distilling Sproozi down to the minimum set of features I can launch with.

If you haven’t already, signup for the super-secret-pre-alpha on the Sproozi site and as soon as I get there, I’ll let you know.
