As for which platform has more development cost, there are many different views. Using Android we no need to spend money on an expensive Mac computer, iOS test machine and $99 year fee for each developer account. While developing iOS apps does not require much testing, screen adaption, debug and script compatibility considerations. Let's see a few views shared by some developers. Nan Li, ERP/SAP/Mobile network/Japan/Apple/KKK@ifanr Because of the performance of iOS, it actually has domina...

  This Is Why Your Website Is Slow

Click for a larger image Ghostery, the browser plugin that allows its users to "track the trackers," just released data on the tags, widgets and analytics on websites that are the worst in terms of slowing page loads to a crawl. Update: Ghostery discovered an error in their original data set. It appears that Millenial Media was not on this year's list at all, and the #2 slot belonged to AdFunky. Both the text and the graph above have been changed to reflect this. Any webmaster worth his or he...

  Why Building a Mobile App is Hard

Kent Nguyen has a great article about how building iOS apps takes a lot of work. And, here at Parse, we agree. Making a well-designed app is not a trivial task. Many non-developers hugely underestimate the amount of sweat and tears that goes into a single app. The big component that is overlooked and that Kent stresses is the server component. An app is not an island. Users expect their apps to richly interact with the internet. This means you need to worry about developing code on servers, com...

The biggest controversy is between Emacs and vi. vi supporters like to say: "Look it's very fast to type in vi, our fingers no need to leave the keyboard, we even no need to use the up,down,left and right keys" Emacs supporters often downplayed this and said: "What's the use of typing fast if I just need to press one key and it equals to dozens keys you type in vi?"In fact, there is another group of people who like to ...

  Output a file with HTTP range header in PHP

When downloading a large file, we may encounter some network issues which causes download termination and only part of the file is downloaded. When the network connection resumes next time, we may need to redownload the file again from the beginning. In order to save bandwidth, http provides a Range parameter in its header which can control the file transfer flow. With the range parameter in the header, we can resume the download from where we stop. Here is a piece of PHP code snippet which uses...
