chwolfe··on Ask HN: What is your favorite non-generic or semi-obscure programming language?
Learning Prolog was one of the better decisions I have made. Not because Prolog jobs are plentiful. Rather, understanding logic programming by broadened my problem-solving skill set.
chwolfe··on Ask HN: Does your company get positive ROI from its ad spend?
Good question! Combination of holdout groups (split testing) based on historical keyword traffic/conversion and tagging paid and natural search entries to compare cannibalization across campaigns.
chwolfe··on Ask HN: Does your company get positive ROI from its ad spend?
I worked in ecommerce for 10 years and got to know the quantitative marketing folks well. All marketing campaigns were tracked and analyzed weekly based on the concept of "marketing income". Marketing income at the order level was defined as: Marketing Income$ = Order Total$ - Cost of Goods$ - Shipping$ - Marketing Expense$.
chwolfe··on How to monetize a small website about research in cancer, ALS
I would imagine many folks who are visiting cancer/ALS content are impacted by the diseases either directly or indirectly. Affiliate marketing (directed to non-profits) seems like a place to start.
chwolfe··on Ask HN: What's was the hardest part about starting to code?
Much like mathematics, programming is learned through action. As a fairly cautious individual, I wanted to understand everything I was about to type as input for the compiler. I would recommend the opposite approach: Copy code examples line by line, and start modifying them with simple changes such as variable names, output strings, etc.

Congrats!

When it comes to Management, I have to second vellum's advice and go with Drucker:

chwolfe··on Mathematicians are chronically lost and confused
The entire post was enjoyable but I found the last paragraph to have the most actionable advice:

What’s much more useful is recording what the deep insights are, and storing them for recollection later. Because every important mathematical idea has a deep insight, and these insights are your best friends. They’re your mathematical “nose,” and they’ll help guide you through the mansion.

chwolfe··on Discovered: Botnet Costing Display Advertisers over $6,000,000 per Month
Before you blacklist the IPs listed in the article, it might be worthwhile to query your transactional history and verify real purchases are not occurring on those addresses.

When I did this, a few of the IPs had a significant number of orders. Interestingly, the IP with the most orders mapped to E! corporate headquarters.

Very cool. It will be interesting to see how successful AppHarbor can be without first establishing a competitor to Azure Appfabric.The service bus and access control inherit in Appfabric makes cloud computing palatable for enterprise companies.

"Down the road there will definitely be a need for data marketplaces, common platforms where producers and consumers of large information sets can connect, just as there are for other commodities."
