The most common mistake is to put profits first. That opens the door for bad things to happen. Numbers become all-important, and almost any behavior is justified in the name of profit. Cheating sets in. Instead, a company’s priority should be to protect and enhance its reputation through ethical behavior. Within the confines of that behavior, its next most important goal should be to attract and keep customers. Third is figuring out how to make money. via blogs.hbr.org It reminds me of...
Yay, new site launched! myAppalogues – App-based electronic catalogues. You can also find the iPhone/iPad app available on Apple Store too In their words: Every day we see merchants willing to spend thousands of dollars on tradeshows, magazine / print, and website campaigns. And then they end up selling at a discount anyway as it’s such a crowded market. We’re not telling merchants what to do, and there are some benefits to tradeshows obviously, but if the world is going to mobile (which it is) and you can easily afford to give it a try (which now you can) then we’re finding that people will do that.” myApp4KIDS is free to download and use and costs a small monthly fee per advertisement. There are no commissions on sales. Merchants can register at www.myappalogues.com and use the Ad Wizard to easily create instant mobile promotions for their products. A few screenshots of the...

I do think the rise of alternative notification channels; sms, mobile push notifications, direct messages on twitter, facebook messaging, etc are going to move some of this kind of thing off of email over time. But today, if you want to drive retention and repeat usage, there isn’t a better way to do it than email. via...
In last few months, we has been developing and iPhone / iPad apps that pull JSON data from an web API frequently. We used Ruby on Rails to do the first version for both website and API service. After trying the first version, customers complained about loading speed. They said that data loading on the mobile app was SLOW. There are two reasons that make Rails based API calls slow: Rails is heavy and blocking (after an API call we do some logging and system shouldn't have wait for logging to return data to clients) Need to join four SQL tables to query data, combine data then convert to JSON Let optimize them! Solutions for (1) are: Rack Apps + Job Queues (Delayed Jobs, Resque …) Non blocking server (Node.js, Goliath …) to fire an action to log info to database, forget it and return JSON to clients Non blocking was chosen because it's fast, it handles more requests and help to avoid managing additional job queues. For (2), de-normalize and pre-calculate JSON is the first step. But there is a table that cannot be de-normalized using SQL. It's listings table that state which item will be showed on which month and in which category. Let say item I will be showed in category C in month M1 and M2 then two rows (I, C, M1) and (I, C, M2) must exist in listings table. After de-normalization and JSON pre-calculation, only it need to join only two tables to get items give a category and a month then combine pre-calculated item JSON and return it to clients. Second step for...
