60 milliseconds is when we notice something isn’t immediate. Any user interaction, that involves sending data over the network or doing heavy computation on it, usually takes way longer than 60 milliseconds. So, we end with a progress bar. There are two broad categories of progress bars, one that shows the absolute/relative progress, a determinate progress bar, and one that does not an indeterminate progress bar.
When the code runs on your servers, you have much more control over the “context” in which it runs. On the mobile devices, the device OS and the user control the context. This difference leads to some subtle implications. One significant set of differences comes from the lack of control of the platform. For server-side code, one can choose from a wide array of languages. For the mobile code, however, the best choice would almost always be the one dictated by the platform - Java/Kotlin on Android and Objective-C/Swift on iOS....

Our brain loves distractions, and multi-tasking gets bored quickly. When we read text or watch a photo, it engages us visually, a video (with audio) engages us even more. The bandwidth of eyes is much larger than the bandwidth of our ears. When we are watching something, it utilizes more bandwidth and hence occupies more of our attention span. Also, given the way our eyes work, we can focus more on the exciting aspect of the visual feed....
In 2001, Amazon’s share price crashed from 100$ to 6$, they had to do a 15% layoff. But it was Jeff Bezos’s perseverance, tenacity and grit because of which Amazon survived. As several startups from the Bay area to Bangalore get a mark-down of their valuations, the question about how many will survive and eventually produce a [positive] return for their investors is being asked. Between what a startup’s real value is and how viable is its business model, the real question to ask is how committed are the founder(s) to make things works....
Apple Siri, Google Now, Amazon Echo, and Microsoft Cortana have garnered a lot of press lately. But one thing which is still missing out is voice-native user experience. Let me illustrate that with the evolution of user experience on touchscreens. When they first came out, there was a stylus, and that’s it. It was an inferior version of the mouse-keyboard-monitor trio. Then some fantastic interactions were invented. Interactions like double tap to zoom, multi-finger rotation, swipe to like/dislike, pull down to refresh, long-press for options, and a Swype keyboard. All of these were native to a touchscreen-based environment. Porting them back to a mouse-keyboard-monitor trio was of limited utility at based and useless at worst.
Yes, it did happen, and no, I am not stupid enough to execute rm -rf *. It was a bit more convoluted than that. I was trying to prepare a customized SD card image for the Android emulator. The fastest way to do that was to mount the SD card on my GNU/Linux machine and modify the files. The files on the SD card have root as the owner. Therefore, the easiest way to maintain a clean state was to make all modifications using sudo....
Standards exist so that products from different vendors can interoperate with each other, for example, sending email from Gmail to Yahoo! mail, and use common interfaces, for example, sockets for electrical appliances. The standardization does not always have to come from imposed standards; sometimes, it comes from the user expectations. For example, the interface of a Calander/Scheduling application is pretty standardized. There is little scope to differentiate a new Calendar application from the existing products like Outlook Calendar, Google Calendar, and iCal while just implementing the standard is still pretty hard....
Here is a summary of things that have happened since I wrote the previous Bitcoin blog post.
In 2013, we saw how internet activists’ snap judgments about the interpretation (or misinterpretation?) of jokes at pycon destroyed the professional career of two individuals (Source: A Dongle Joke That Spiraled Way Out Of Control). The internet activism first sympathized with Adria Richards and then decided to side with the developer, eventually, both of them (and SendGrid customers temporarily) took a major hit which could probably have been resolved offline and would have never become a part of permanent history. As if this was not enough, this year the same story has been repeated with Gurubaksh Chahal and his girlfriend Juliet Kakish. The claim goes that he allegedly hit his girlfriend 117 times and she allegedly suffered bruises and injuries, there is an alleged video of that proving the same (I haven’t been able to find one yet that does not imply it does not exist though) (Source: A Letter To The Board Members Of RadiumOne).
