jdrock··on Facebook employee responds on robots.txt controversy
It's not Facebook's data. It's the users' data.
jdrock··on Facebook employee responds on robots.txt controversy
In my personal opinion, the Facebook employee's response shows that he doesn't understand the company's high-level business goals. Their developers may think they are building an open web, but it's very clear the company is only interested in a closed web they control.

Based on my interaction with website API developers, most of them honestly believe that they are building an open web. But let's face it, the API is a benefit to them and creates a critical dependency for the user of the API. It's basically vendor lock-in.

jdrock··on How to listen to vuvuzela without all the annoying football
I thought this would be instructions on how to configure my TV to cancel out all frequencies EXCEPT the vuvuzela. Alas :(
jdrock··on Save My Life: an update
I'm kind of surprised Celiac was not tested before. I know a quite a few people with it, so I thought it was a fairly common thing to test for and identify.
jdrock··on Ask HN: Is there a great open source crawler?
Understood. We do work with folks on custom per-use plans, but we just need to figure out what your requirements are so that we can see if there's some way for us to help.

Tooting my own horn, but this takes all of 1 minute in 80legs if you've got the right regex.
jdrock··on The Real Cost of Owning a Car
I have a fairly nice car. Have owned it for 7 years now. While there have been minor problems like scrapes on the rims, trim peeling, etc., the engine, transmission and all the real guts of the car have performed flawlessly the entire time. The car has been paid off for 4 years.

I feel I could drive this car for another 5 years at least. That would be at least 12 years without purchasing a car and 8 years without making a car payment.

My car was expensive, but I feel it was engineered so well that it can last. Quality cars last a long time.

jdrock··on The Real Cost of Owning a Car
No, it's not. If you're steadily earning a 10% return on your investment, year over year, you are doing amazingly well and should stop doing whatever day job you have now.
jdrock··on Running a start-up is great, growing a business is boring
I kind of think you're countering yourself here.

Just like only showing relevant news is an interesting challenge, so is only showing relevant ads. Advertisers don't want to show you ads you're not interested in; they want to show you ads you'll actually find useful. In many ways, that's a much more interesting challenge than showing relevant news.

Extending the advertising example, it's also a very interesting challenge to show people that highly-targeted ads can be a good thing. Just like it's an interesting challenge to convince advertisers to use your ad platform. Although they are not technical challenges, they are very interesting business challenges.

jdrock··on Running a start-up is great, growing a business is boring
I suppose it depends on your personality, perspective and how you grow your company's culture.

I just finished reading Tony Hsieh's upcoming book, Delivering Happiness. He describes how LinkExchange, his first big company, became boring to grow because the company culture wasn't fun. But he still enjoys working at Zappos because he and his execs managed to keep the company culture fun and interesting. He doesn't know everyone there, but it has a great feel to it. Keeping his employees engaged, serving his customers, etc. are all great joys to him.

Note that I'm not saying Zappos still feels like a startup. I think from the book it's apparent that it doesn't have a startup culture at all. But it does have an "engaged" culture. Everyone enjoys what they do.

Side note: I don't recommend reading the book. There are about 10 pages in it I actually felt I could generalize to be useful.

jdrock··on 80legs is looking for interns or contract workers
A local intern would be full time.

Remote work would depend on the ability of the programmer. We have a few dozen 80apps that need to be produced for various crawl packages right now (more coming). I expect each one would take 1-3 days of programming.

Java is the only language we can use on the JVMs that run on the nodes in our grid computing system.

Other languages (Jython, JRuby) require techniques that break the security sandbox used by the JVMs.

jdrock··on 80legs is looking for interns or contract workers
Anyone we hire will be compensated properly.

The descriptions on the pages are fairly specific about the difference in responsibility for local vs remote.

The remote work is admittedly more straightforward, cut-and-dry programming. It's suitable for a student or freelancer looking for some entry-level experience or extra work.

Anyone that works locally will be exposed to some of the more complicated tasks we have and take on more responsibility.

We would really prefer to have someone local, but we have to be realistic about our potential candidate pool in Houston.

jdrock··on England to win World Cup, says JPM quant model
Soccer should be much harder to quantify with stats because the game is basically a set of two continuous events.

As a contrast, baseball is easier to quantify with stats because it's a series of discrete events.

In most sports statistical analysis, you try and drill down to a discrete event. In baseball, it's something like at-bat or on-base. In basketball, it's per-possession (though this isn't enough). But in soccer, what can you do? Per-possession is difficult because it overlooks the 21 other players on the field. Everything is team-oriented.

jdrock··on Zendesk raises their prices 60%-300%, users predictably revolt
You can still experiment with pretty much everything except the API using the basic (free) plan, as long as you crawl fewer than 100,000 pages per job.
jdrock··on Zendesk raises their prices 60%-300%, users predictably revolt
We increased prices at 80legs from on-demand ($2.00 per million pages) to subscription + on-demand (starting at $99 per month + $2.00 per million pages).

It was a success for us. Here's why:

1. It was early on - just a few months after our public launch.

2. We offered a limited free version in conjunction with the price increase.

3. We lost some customers, but they were only worth max $10 per month. We were able to work with some of those customers to setup custom plans that met their needs.

4. The customers we did keep went from being worth $50 - $100 per month to $100 minimum per month.

5. Our major competitors charge thousands per month, so we were still absurdly cheaper than them.

jdrock··on No One Wins In Business Plan Competitions
80legs participated in a business plan competition at Rice University while I was still getting an MBA there. We were one of the finalists, but not the top winner.

That was a year ago. I have since done some basic searching to see what the other finalists have done since then. As far as I can tell, only one (the winner) has done anything significant so far, and that's just raising money. Granted, it's just a web search, but it seems the rest have just done things like win other competitions, get grant money, etc.

We are the only ones actively engaged in business. And we only entered the competition for fun. (We used our winnings for free lunches.)

jdrock··on A Robot That Balances on a Ball
I wonder if this would make bi-pedal movement obsolete, or at least less important to innovate. There would still be need to move up and down steps, but this form factor seems much more compact than current bi-pedal robots.
jdrock··on Match.com no longer top dating site, sends in the lawyers
I can't see how Match.com could possibly defend their case in court if they tried to sue. They'd essentially be asking a competing firm to reveal their trade secrets.
jdrock··on Obama administration wanted warrantless access rights to most US email
"For its part, the Justice Department has taken a legalistic approach: a 17-page brief it filed last month acknowledges that federal law requires search warrants for messages in "electronic storage" that are less than 181 days old. But, Assistant U.S. Attorney Pegeen Rhyne writes in a government brief, the Yahoo Mail messages don't meet that definition.

"Previously opened e-mail is not in 'electronic storage,'" Rhyne wrote in a motion filed last month"

Am I missing something here? How is web-based email not in electronic storage? Where is it then?

jdrock··on 80legs releases python API
The API lets you control job submission, result delivery, etc. 80apps control how you process the content on a per-page basis.
jdrock··on 80legs releases python API
The Ruby API is still on the to-do list! Note that a Ruby API is in the works, but Ruby 80apps are not.
jdrock··on 80legs releases python API
Our customers do things like the following:

1. Monitor online ad distribution

2. Build directories of people on the web

3. Check for IP violoations (digital watermarking, etc.)

4. Build niche, localized search engines (picture searching, regional searching, etc.)

5. Collect information on product pricing, retail data, etc.

Crawling gets a bad rap. It's useful for a bunch of stuff.

jdrock··on How I got sued by Facebook
User-agent: *

Disallow: /directory/people/*

Disallow: /directory/pages/*

Done. Google crawls Facebook. Every social media monitoring company crawls Facebook (and every other social network). Tons of other companies do the same every day. I know this because many of these companies are our customers.

What really irks me is that Pete collected valuable data and whoever he shared it with was probably able to derive added value from that data - in ways that Facebook is not doing. Facebook is prohibiting value creation.

What's the monetization strategy??
jdrock··on Ask HN: What's the most simple way to accept monthly subscription fees?
We use Google Checkout. Fees are comparable to PayPal.. documentation is much better. There are plenty of other 3rd party solutions, but GC and PP are probably the best two.
jdrock··on Responding to jacquesm's challenge
If anyone wants to use 80legs for this challenge, just drop us a line at http://www.80legs.com/contact.html. We might be able to set up some custom free plans.
jdrock··on Why SXSW Sucks
Interestingly enough, Jolie didn't approve my comment on her blog that suggested she might be out of the loop.
jdrock··on Why SXSW Sucks
Well I think your definition of tech-focused is too narrow for me, but fair enough.

User Groups are more for that stuff. The cool thing about SXSW is that you can totally set up an impromptu user group and get 20-50 attendees if you want. In fact, that is how the Data meetup happened last year.

jdrock··on Why SXSW Sucks
I think they had video there.. check the Infochimps blog for info: http://blog.infochimps.org/ (not there yet, but hopefully they'll post it if it exists).
