Could anyone help me build a hacker news with tags? I am asking only those who are interested to have it as well because I only have a budget for the hosting for this.

The point is to be able to search through the whole archive using tags/keywords.

example of tags:

'security'

'crm'

'a/b testing'

'optimization'

'http', 'ssl', 'domain name'

'scala', 'c++', 'php', etc

'lua'

'sql'

'marketing'

'website'

'landing page'

=> get all posts that relate to each tag (and combinations of tags) sorted by points of individual posts/comments.

To do list: 1. import all hacker news database 2. insert in database all tags for all posts/comments, using an algorithm similar to the Kaggle Keyword Extraction algo (https://www.kaggle.com/c/facebook-recruiting-iii-keyword-extraction), which will need to be refined. 3. create great user interface to the new database

------- or if no-one has the time, could anyone advise me on how to download the whole hacker news database?

I propose for all to list needs and business ideas, and vote. This can be used both ways: to say 'I need this', or to ask 'How many people need this?'

Last week I started wondering what I had learned over the last 12 months. What did I learn that actually make a difference on my bank account? Of course I learned many small things (tricks in PHP, javascript, css, http server optimization, etc.) But these things didn't really make a difference. Still there were a couple of things that truly were "breakthroughs" for me, even though there might seem trivial to many.

Here are two things I learned in the last 12 months that "moved the needle" for me because they both helped me improve my conversion rate to a point where I can see the possibility of a positive Adwords ROI:

-> Adwords / I can track conversion by keywords, and associate values to conversions depending on user input

-> Website speed / Cloudflare has a free CDN that works well (using the full performance optimization gives me a 95 score on Chrome Page speed, and Google Analytics seem to report page load under 2 seconds - although it is a bit early to tell for sure)

What breakthroughs have you made in the last 12 months? What significant lesson have you learned?

I am trying to optimize my adwords campaign, and running into the 'statistical significance' question.

I read this great post from Paras Chopra here: http://visualwebsiteoptimizer.com/split-testing-blog/ab-testing-significance-calculator-spreadsheet-in-excel/

Though in my case I started my campaign with many keywords (about 400 keywords), and I now have the following:

Keyword group A (10 keywords - the "best"): 47 clicks, 16 conversions

Keyword group B (390 keywords - the rest): 244 clicks, 18 conversions

If I apply these data into the A/B Testing Significance calculator, I obtain a 99% confidence that A is better than B. But does it really work with a group of keywords, or is this calculation meant to be used only for strict "singular" test cases?
