Eric Ries and I recently sat down to talk about minimum viable products: the product with just the necessary features to get money and feedback from early adopters.

The minimum viable product (MVP) is often an ad on Google. Or a PowerPoint slide. Or a dialog box. Or a landing page. You can often build it in a day or a week.

I recorded the interview and synchronized it with some simple slides below. That’s my favorite way to consume the audio. You can also find a transcript and stand-alone audio below. Eric also highlighted some excerpts from the conversation on Lessons Learned. Let me know what you think — I’m especially interested if you like the synchronized audio and slides.

Create the 'Coming Soon' page first, with a 'contact me when its available' form, and only build that form of your product if people sign up. Rework your concept until they do.

Gold star.

I recently had trouble manipulating an ENUM field I had created in PostgreSQL. I couldn’t find any suggestions or samples easily on Google or in the manual and was able to get it to work, so I post it here. The basic premise is there is an ENUM field type created, I need more possible values and to preserve the existing values I already have to keep code working.

So far, so remarkable – and if this were all there was to Gobekli Tepe, it would already be a dazzling site: a Turkish Stonehenge, or a Kurdish Carnac. But Gobekli Tepe isn’t just this. One unique factor puts it in the archæological stratosphere.

Gobekli Tepe is staggeringly ancient. Carbon dating of organic matter adhering to the megaliths shows that the complex is 12,000 years old. That is to say, it was built around 10,000–9,000 BC. By comparison, Stonehenge was built around 2,000–2,500 BC. Prior to the discovery and dating of Gobekli Tepe, the most ancient megalithic complex was thought to be in Malta, dated around 3,500BC.

Really, really old and neat shit discovered in Turkey.

The crash has laid bare many unpleasant truths about the United States. One of the most alarming, says a former chief economist of the International Monetary Fund, is that the finance industry has effectively captured our government—a state of affairs that more typically describes emerging markets, and is at the center of many emerging-market crises. If the IMF’s staff could speak freely about the U.S., it would tell us what it tells all countries in this situation: recovery will fail unless we break the financial oligarchy that is blocking essential reform. And if we are to prevent a true depression, we’re running out of time.

Dear Paul Graham,

Everyone but you sucks.

Allow me to explain. I either live in the valley or want to live in the valley. I idolize you and love this site. You are the smartest guy on planet earth, and anyone that copies you is pathetic because they could never be as cool as you. Who do they think they are!?

Now that I've impressed you with flattery and have defeated your enemies on your behalf, I'd like to tell you about Project Tomacco. With your help, we can caffeinate tomatoes and hook every college kid on a healthy alternative to coffee. Did you know tomatoes have antioxidants that fight cancer? Thats right, we're helping to prevent cancer. We're going to change the world, Paul, one tomato at a time.

Is there a way to attach a spreadsheet to a comment on hacker news? Because my projections are going to blow you away. If we get one percent of the tomato market you're going to be a very rich(er) man, Paul.

Signed,

Valley Hater

In this episode I pitch Paul Graham on 'Project Tomacco.'

Job Scheduling in Hadoop

When Hadoop started out, it was designed mainly for running large batch jobs such as web indexing and log mining. Users submitted jobs to a queue, and the cluster ran them in order. However, as organizations placed more data in their Hadoop clusters and developed more computations they wanted to run, another use case became attractive: sharing a MapReduce cluster between multiple users. The benefits of sharing are tremendous: with all the data in one place, users can run queries that they may never have been able to execute otherwise, and costs go down because system utilization is higher than building a separate Hadoop cluster for each group. However, sharing requires support from the Hadoop job scheduler to provide guaranteed capacity to production jobs and good response time to interactive jobs while allocating resources fairly between users.

This July, the scheduler in Hadoop became a pluggable component and opened the door for innovation in this space. The result was two schedulers for multi-user workloads: the Fair Scheduler, developed at Facebook, and the Capacity Scheduler, developed at Yahoo.
