nwenzel··on Show HN: We got tired of getting gifts we don't like/need, so we made this
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 TripIt for inspiration on the registration process. You can create a travel plan without registering. Once it's created, then you have a reason to register, so you do.

nwenzel··on Startup = Growth
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 contract. I mean the signature on the check.

I agree with you that pg's point about startup growth is not invalidated by the realities of enterprise selling. But I think te way past those realities is to change the rules of the game. The "sale" should be a low-friction agreement to do business at some cost per unit/user/GB/etc. Growth is the. The ability of the product to go viral within the account. Essentially, it becomes the same process as a consumer sale with the one additional step of getting approved to sell into that batch of consumers.

While that might seem to be a big negative against starting an enterprise business, the advantage is that you're then convincing people to spend someone else's money which is easier than convincing them to spend their own. How else could a $.99 app look, feel, perform better than a $100,000 peice of enterprise software.

nwenzel··on Startup = Growth
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 a hard time qualifying on several fronts (market size, growth rate, growth interval). I am particularly interested in the B2B style of startup because I run an Enterprise Startu-er... Enterprise New Company focused on serving the insurance industry. A B2B Startup, it would seem, would have to link customer charges to something that can grow without a new sales contract. I guess, the trick to achieving high growth rates is to create viral growth inside an existing account. Growth in the B2B space will be large jumps (with a new contract) followed by organic growth or not (within the bounds of the existing sales contract). It seems to follow then that since the purchase agreement is the painful and tough and slow part, a B2B Startup would want to have a Freemium or some other type of contract with low/no startup costs and higher per user/GB/account/server/unit costs.

Gives me some new direction on pricing.

On an unrelated note, I'll disagree with other comments of "favorite pg essays" and say that "Wealth" was the best by an order of magnitude. http://paulgraham.com/wealth.html

nwenzel··on Ask HN: Does knowing Python give you a significant head start learning Django?
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 had a complex problem and needed a full-featured solution. I'll give Flask a second look.
nwenzel··on Ask HN: Does knowing Python give you a significant head start learning Django?
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.
nwenzel··on Ask HN: what do you think about "signin without logging in" for your startup?
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 on our first date.

I'm sure there are levels of access that can be granted to slowly introduce users to your app.

nwenzel··on Tools to get started in machine learning
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 to me feels like Python + NumPy. I'd say Octave has more in common with R than with Python.

Given the choice between Octave and R, I'd choose R for the more robust user community and incredibly diverse and thorough selections of libraries.

nwenzel··on Selling Yourself
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 must mean that there was either a demand for it or a belief that readers would want to know about the articles with future potential to make the first page. Anecdotal at best, but it seems to support the idea that there is some innate bias toward the next new thing.

nwenzel··on Thoughts on Machine Learning – Dealing with Skewed Classes
Good post on the exact problem I ran into when developing a machine learning algorithm to identify rule violations (basically fraud) based on self-reported descriptive text data. The few records that are "fraud" are precious from a training standpoint.

I found it helpful to start by over-representing the rare class and then slowly bring the balance back to the observed percentages.

The main reason for my over-representation of the rare class was that rare case was often not correctly identified (many false negatives) in the so-called "Gold Standard" training data. By over-representing the rare case, I was able to build a better training set while tuning your algorithm.

I'd be interested to hear if others flush out false positives in a similar/different manner (for the Skewed/Rare Class problems described by the article).

nwenzel··on Arrays in Postgres
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 but it has potential as part of your toolbelt.
nwenzel··on Trends in Data Modeling
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. Informatica was pretty quick to jump on the Hadoop train.
nwenzel··on Hiring Employee #1
Don't forget that when you get to the point of Hiring Employee #1, tell them that you may have to fire them or that they may be let go through not fault of their own if the revenue and expenses don't line up the right way.

I have had that conversation with each of my new hires (we're at 10 people). I want them to know up front that they're taking on some risk and that there's no free pass in a small company in the same way that there is in a big company.

That all may seem obvious to anyone reading here. It may seem to be an implied part of joining a small company (or any company). But that part of the conversation is important. It also reminds people that their work has actual value.

nwenzel··on 5 Million Farmers Sue Monsanto for $7.7 Billion
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 stolen property. So they want a cut of the gain from the stolen property.

The farmers say that pollen goes where the wind blows it and plants and their DNA spread naturally. The farmers say that they did not intend to grow a Monsanto product but because the Monsanto products grow in greater densities and are more robust than naturally growing soy and other crops, the Monsanto products crowd out the farmer's naturally growing products.

nwenzel··on 5 Million Farmers Sue Monsanto for $7.7 Billion
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, Monsanto sues a farmer because a farmer's land contains some of Monsanto's product. Fine, their product is essentially DNA, but they're allowed to call it their product. Fighting the patent is a losing fight. Right or wrong, it's a battle that won't be won until Kucinich is in the White House.

I've wondered why farmers don't file a counter-claim of trespassing since Monsanto allowed or caused their agents (both the patented DNA and whomever discovered the Monsanto plant) to enter a farmer's property. Additionally, it seems like there would be a case for destruction of property since the genetically modified seeds and plants crowd out the farmer's seeds and plants. Lastly, if the farmers really wanted to hit Monsanto with some irony, they should sue to have Monsanto pay for the removal of the modified seeds and plants. The farmer would have to argue that it is Monsanto's responsibility to prevent the outward spread of their crop. I'm sure the right judge could be found who would draw the comparison to breaking and entering someone's home.

But I'm reminded of a couple simple facts. You don't have to be right to sue someone. You don't have to be in the wrong to get sued. Win or loose, it's not cheap to go to court.

nwenzel··on Restoring A 30-Year-Old Apple II Plus
Wrote my first programs on an Apple II Plus. Learned about planning ahead with line numbering, flow control with loops and goto, and debugging. Still remember upgrading memory, I think to 48k or 64k. Good times. Great lessons. Good reminder of why learning to code is a good thing even if you don't become a programmer.
nwenzel··on Chromebox
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.
nwenzel··on Calif. students rank 47th in science
Are they really going to blame statistical significance for a 47th place showing? As if a bigger sample pushes CA up to a podium finish.

Also found the "large urban districts" comment interesting. I understand it's an Orange County paper in which an Orange County supervisor is telling his constituents that the story isn't representative of Orange County. But it shouldn't be okay for "urban" kids to be 47th in science?

nwenzel··on My Recent Experience With Square
Seems like both sides just needed to understand that there's a person at the other end of the email / support form. None of those emails really sounded like a person talking to another person. Imagine those notes as a transcript of an in person conversation rather than emails.

Sounds like Square can take care of their core business with decent competency, but as with many young companies, they may not have all the kinks worked out when something gets outside their normal decision tree.

nwenzel··on Redditor: Am I a scumbag for automating my manual work and making more money?
Big companies are built to fail. The variety of departments and personal empires built by managers of those departments create an environment where innovation (or even the ability to ask "is there a better way?") gets crushed because "that's not the way we do things." Departmental managers don't optimize for company success. They optimize for personal success. A bigger staff and bigger budget is a promotion. Saving money means a smaller budget means a de facto demotion.

Smart people move on and the big companies are left to wonder why it's so hard to find good talent.

nwenzel··on ABC takes 5% equity or 2% royalty from all companies that appear on Shark Tank
Interesting what they add in at the end: "The Shark Tank Entities or their designee(s) will give good faith consideration to my expressed preference as to the form of the Option (i.e., royalty or warrants)"

As if they'll agree to take the lower return option just because someone has expressed their preference. Not sure if they're trying to be nice, or just trying to make you think you have some choice in the matter.

nwenzel··on Looking to Get Creative? Leave the Echo Chamber. Drink. Skip SxSW.
So then the question that follows is how do you prevent any niche gathering, digital or real world, from becoming an echo chamber? Don't all like-minded groups eventually become echo chambers? Even HN runs a risk of becoming an echo chamber as a group of like-minded people that quickly popularize a news story and then comment/respond in similar fashion.

I'm not saying that to bash HN. I love HN. I learn more from the stories and comments than any other source. I think "regular news" (RN?) is mostly a mix of garbage and entertainment. I like having like-minded individuals to learn from. I don't want to spend time in groups that talk about which Hollywood celebrity of the month is getting married/divorced/hired/fired/honored/dissed.

I think a diversity of participants, diversity of opinion, and diversity of passions is a good start. I think we have that here (even if in a somewhat narrow slice of diversity). After that, do we just hope for the best?

nwenzel··on Posterous acquired by Twitter
So now when I tweet, will it push that tweet to Twitter so all my Twitter followers will know that I tweeted?
nwenzel··on Why Are Lawyers So Expensive Even With The Excess Supply Of Lawyers?
Supply Induced Demand. They're out there, so you need one too. The other guy has 2, you better get 2, too. No such thing as an "excess supply."
nwenzel··on Benefits of getting up early even if you don't want to code
"Never hit snooze." I love it! I don't understand snooze. If you're going to snooze, just set your alarm 5 minutes later. Otherwise, just get up.
