The other day I watched a TED video where the presenter urged the audience to ask the question What do you really want? That got me thinking what do I really want. It is an interesting question to ask myself, since I have tried different roles and responsibilites - broad and deep - in the last couple of years. So I was pleasantly surprised when I found the book Data Structures and Algorithms in C++ by Adam Drozdek on my bookshelf.
One of the challenges of mobile application development is to ensure that the application is resilient to various error responses from the services that are consumed by the application. Mobile devices are more susceptible to network connectivity issues, timeout etc. So we need to take extra care to make sure that we test all error scenarios and handle them in a meaningful manner. What and Why of Mocking Even though we are convinced about the benefits of testing server errors, these services are running in Production serving real customer requests.
I have been using GraphQL in my work project for a few months now and I love it. But all my learnings of this technology have been in a hurry and mainly from a consumption standpoint as a mobile developer. So I wanted to learn it much deeper, tinker with it and finally write this blog to share my learnings and cement my understanding. Finally got the time to do it this weekend.
In this post, I would like to share what’s new in Swift 4.2. All the code displayed in this post is available at my GitHub repo my-learnings/Swift4.2. Random Number Generation Swift 4.2 added random number generator API to standard library. You can use it on Int, Double, Float, CGFloat and Bool. It also provides a convenient API randomElement which returns a random element from a sequence It also provides the APIs shuffle and shuffled to shuffle a sequence 1 2 let randomInt = Int.
I am at the Houston IAH airport waiting to board the flight to go home after 3 days of inspiration, motivation, technology, friendship and pure awesomeness. Yes, I was at Grace Hopper Celebration 2018 (aka GHC 2018), the world’s biggest gathering of women technologists. This year, GHC has 20,000 attendees representing 90 countries. It was such an inspiring experience for me that I thought I should share my experiences and learnings with you my friends.
Fastlane is a suite of simple yet powerful tools to automate building and releasing iOS and Android apps. It takes care of the mundane tasks of mobile application development like generating screenshots, managing provisioning profiles, code signing, beta deployments and releasing the application. It is very popular in the mobile developer community and the best part - it is completely open source. The Toolchain fastlane comes out-of-the-box with a set of very good tools (better known as actions) such as:
I had the wonderful opportunity to attend Google I/O last week and absolutely loved it. I learned a lot of things during the three days. Btw, it was tiring too with the continuous sessions and the sunny Sun. This post is an attempt to share the main highlights and the announcements that I found interesting. If you attended the event or watched the sessions online, let me know if there were more things that you found interesting.
I use Xcode playground a lot in order to write code snippets - either to try out something that I read in a blog, or to demonstrate a code improvement that I want to suggest in a code review, or sometimes even to prototype a design before doing the full-blown implementation in Xcode project. During this experimentation phase, the correctness of the code was verified by analyzing the ouput displayed on the right-hand side column of the playground.
Realm is a company that I respect a lot because of their support for mobile developers and the open nature nature of their offerings. Their easy-to-use, blazingly fast Mobile database software supports all mobile platforms - iOS, Android, React Native and Xamarin, in Java, ObjC, Swift and C#. That is why I am happy to see that today they announced Realm Mobile Platform that combines Realm client side database with server-side technology (Object Server as they call it).
As part of my Machine Learning course, I learned a useful trick which I will share hoping that it may help someone or I myself can refer to it later. The problem at hand was how to display the mathematical expressions that calculate cost function, gradient descent etc. in a blog or web page. In OneNote, you can do it using OneNote Equation tool earlier, but I wanted to do the same in my blog posts.
