People seem to be really put off by the lack of interactivity. Interactivity might be fun, but it mostly gets in the way and can be an impediment to telling a story because it let's developers pass the buck to the end user. Interactivity is

I saw the same thing. PG is pretty consistent with that tagline. So presumably the VCs knew it would be there. If those VCs didn't want to give the appearance of agreement, they probably would have asked to have their names witheld. PG also

I found Machine Learning for Hackers to be good as a practical, case study based book for learning to apply and understand what is going on in several machine learning problems. http://shop.oreilly.com/product/0636920018483.do http://www

Too bad his message was lost by writing a 1,211 word article, explaining 2 different suspicious reviews, with multiple graphics, each with way too many words to read. Would have been the perfect time to sit on his hands and hire a PR firm t

As a founder who doesn't consider myself to be the "sales guy", this post changed my whole view. It showed me that sales is a problem to optimize and solve, not a genetically predetermined outcome.

As for the high cost of living, try looking at it from a different angle. Instead of thinking about how much more you can get for your money elsewhere, ask why are all those other places worth so much less. I'm not saying the math adds up t

Other than the architecture of their multi-cluster management system, which us certainly fascinating, I found two interesting points. 1) Use of S3 as the data storage platform allows for Production, ad hoc, analytic, and "personal" clusters

Random Forests are interesting because they are designed to make many, many bad decisions that cancel each other out leaving only the good decisions behind. To oversimplify, each of the many, many decision trees is going to do a poor job bu

I can guarantee it will go for more than $500. If not to me for what I bid, then it will go even higher than what I bid... which is a secret. So no one bid $502, okay.

The first thing you ask for from a user is their email address and/or Facebook account? Do that last. Get the user to create a wish list first. Registration is a barrier to getting users. Save it for the end or as late as possible. Look to

From my experience selling services and products to large companies for the past 10 years, "interest" doesn't mean much. Everyone is interested. You don't have anything until you see the signature. And I don't mean the signature on the cont

Based on required growth rates and measurement intervals (5-10% per week), there would seem to be a pretty heavy bias towards the consumer space. B2B or so-called Enterprise Companies, especially industry-specific new companies, would have

Thanks. I've played with Flask a bit but haven't really gotten into anything too intense. That is a good idea to see if Flask can take care of me for an initial prototype/alpha level release. I guess I jumped straight to Django thinking I h

Thanks. I'm more computer-sciencie myself. Or maybe more data-science. I think I'll go through a tutorial for both and see what happens.

I hate signing it when I'm first exploring an app. See DJ Patil's talks on building data driven apps. Our (user + application) first interaction is like a first date. I'm not giving you access to my Facebook/Twitter/LinkedIn/Google account

I have used Octave but only for the Coursera ML Class, not actual production use. My understanding is that it is the open source version of Matlab capable of running many Matlab programs. I learned Octave first, then R, then Python. Octave

In all the very good discussion here, and not one mention of the menu at the top of the HN page. The first text link in the menu bar is... "new" There's an entire section devoted to new, or future Page 1 articles. The inclusion of the link

The MADlib add-on out of UC Berkeley for Postgres and Greenplum uses arrays for inputs into its algorithms. MADlib.net is worth checking out for some in-database analytic and machine learning goodness. It's not going to replace R or python

What is this going to look like for document stores, columnar databases, key/value pair and other so-called NoSQL databases where the data (or the map/reduce program) is the model? I'm interested to see how these products and vendors evolve

Monsanto's lawsuits against farmers are aimed at farmers that did not buy Monsanto seed. Monsanto says that because their seed and their plants are growing on a farmer's land, that farmer must have stolen the seed and is benefiting from sto

Does hating on Monsanto mean you can jump directly to Monsanto as the cause of the farmer suicides? Does a farmer suicide every 30 minutes sound a little high to anyone else? That would be 48 / day or over 17k / year. As for the lawsuit, Mo

I get that Google wants to try weird stuff. But how did Samsung green light this adventure? I can't imagine that it's easy/cheap to produce these things in small production runs.
