This is actually the hard part, and the failure at this point actually prevents us from moving towards with Xamarin.
We have been developing with native iOS and Android for 6 years, with lots of legacy code and libraries. Our libraries in both iOS and Android can have up to 20-30,000 lines of code. To migrate all of them to Xamarin would be a huge deal. The only solution is to connect Xamarin with those libraries.
We have libraries in 3 languages: Objective-C, Swift and Java. The first trouble came up when Xamarin could not connect with Swift framework. In our experiment, we took the risk and port 1 of our library into Objective-C. The Swift framework issue should have signaled us that something was not going right.
Anyways, we move forward with our intention to write a real project, working on both iOS and Android, and connect with 5 of our libraries and use 3 cocoapods frameworks/libraries.
For the libraries we wrote, there was not much problem, except the Swift issue mentioned above. However, with cocoapods, when people write code in all shapes and forms, the API definition kept having weird issues that we could not comprehend. We spent 3-4 man days on this, and still wasn’t sure that if the code would work or not.
We will discuss more about what binding issues we have with Xamarin that forced us to change the direction: to try to at least make a workable app with missing elements and libraries working in Xamarin
We are trying Xamarin as our cross platform approach. And we have learnt many things along the way, some of them were the old approach of Static Library, the API definition and how the code structure and the API design of Xamarin and iOS are somehow different.
We have quite a big codebase (more than 100 thousand lines of code) in iOS and Android in native, mainly because we deal mostly with Video Processing and some native features. We use frameworks a lot to share code between different apps. I have been looking for ways to port the code from iOS to Android in a smooth and cost saving way.
There are multiple steps that I plan to go through when adapting Cross Platform:
– Same or similar architecture between iOS and Android codebase
– Prepare the library in correct format to be reused in the Cross Platform
– Prepare the Binding
– Prepare the team with C# knowledge to migrate the codebase
– Design the module and how best the app will be separated between Shared Module and iOS Module
There are times that your app collects a whole lot of data (by capturing it live or by downloading from a third party, or import from email), and you want to do a whole ton of reports and visualisations inside your app. .
To do lots of computing inside your smartphone is a very challenging job, as I have experienced myself in processing video data. A small trick is to use your GPU, which could be 10-100 times faster than your CPU in calculating floating point.
Setting up a GPU shader and calculation could be a huge task for anybody who are not familiar with OpenGL. So, this excellent GPGPU library could help you a lot, all you need to do is to change the calculation inside the vsh file. I am planning to make it even easier for anybody to use in the near future.
Software applications and resources that can allow business owners to reduce their overhead and operational costs may be a resource that few startups can afford to do without. Resources that can allow you to more easily and effectively track your electric consumption, curb demand for costly utilities or help you find the best , electric companies in Hamilton Texas, and surrounding regions have many benefits for smaller businesses and startups that are seeking to reduce the cost of their energy usage. Finding and making use of the best apps can ensure that your business is able to make use of more competitive utility rates and reduce costly waste and excessive energy consumption.
Choosing the Right Energy Provider
Paying too much for any resource could be a serious misstep, one that a business operating with fixed or limited financial resources may not be able to make. Sorting through your options and comparing electric providers and utility services in an effort to find the most cost-effective options and the greatest values can be a daunting task when you lack for the right resources to aid you in your search. Applications able to provide real time pricing information and easier navigation of the providers you have to choose from can ensure you are able to find the most beneficial options for your electrical service.
Tracking Consumption for Greater Energy Efficiency
Having to keep tabs on the operational habits and costs of powering your business is a labor intensive task, one that may rob yourself and staff of energy that would be better spent on more important matters. Software that can speed up or automate the process will ensure that you are able to stay informed about the level and cost of power consumption your operation is resulting in. Superior information may be required in order to more effectively and successfully curb your consumption.
Reducing Electric Waste
Fixtures and appliances that are not as efficient as they could be, devices that are being powered when not required and other habits and situations that could be costing you more than you might realize are all situations that can be more effectively remedied when you have access to the right information. Tracking your electrical consumption with a software application can allow you to target and identify any aspect of your operations or working process that could be made more efficient. Using less energy will reduce your utility bills and overhead expenses and may allow your business to become more profitable as a result.
Finding the Best Resources
With a number of applications to choose from, finding and selecting the best of them could seem like quite the challenge. Conducting a little research and finding the applications and software resources that will be of most benefit for your business will ensure that you do not lack for a superior resource. The tools you need to ensure your business is able to be made more efficient and less costly could make a big impact on the results and success of your efforts.
I normally hear from Windows developer to say that their Windows market share is much bigger than the total of iOS and Android together. And the sales of Windows 8 has bypassed all the sales of iOS and Android from the beginning to now.
Windows Phone 8
It is quite unfair to compare the whole Windows 8 with iOS or Android. And if we do take that demand into PCs and laptops, then why the hell we do not compare the supply side? It is very clear that if Windows 8 could be a shared platform between PCs, tablets and phones, then all the old software, all the old games would have beome compatible to the Windows 8 system in the short amount of time. And many apps for tablets and phones would be quite different than the ones in PC. No, I don’t mean technology, I am talking about the business model, the purpose of the software.
I don’t mean that iOS and Android is a better market than Windows Phone for indie business. These markets have become very competitive and continue being so. You either have to figure out a market niche or be very lucky.
I have a long support for open source system, the open standard, a more open and shared data in the web. 3 years ago, I thought that the win of Android is obvious and the reality has proven me right. I was confident with my knowledge and guessing until I read a long fan boy of Apple. Yes, he is a fan boy of Apple, and the article has really favoured Apple. But he made an important point great product wins. Not the great product in terms of technology, nor in terms of openess. It is a great product in users’ minds, either by its value provision or by good marketing.
By opening the platform, Android opens the door for more hardware suppliers. But that openess means nothing if the operating system sucks, it means nothing if the compatibility and the user interface are not good. Looking at Linux and all the free open source operating system. They are more opened, easier to adopt into the hardware by the suppliers, but they suck. Either the UI, the lack of applications and features, but they suck.
We can see the new hype about education, health care or photography. I believe that in this new era of technology startup, it is time that we are innovating in each industry, to transform the industry into a better format. We have technology there, we have social network there, we have better design there, in iOS or Android platform. The technology industry have gone quite far comparing to other industries like education, healthcare, design, news, food, lifestyle.
We have seen innovations in Education with Coursera, Ucademy, Khan Academy… We have seen more innovations is coming in Healthcare with Misfit Wearable…News is already transformed with iPad, iPhone, social network and how we share news together…. I agree with the article:
The only way out of this innovation gridlock is an expansion in founding team diversity. I believe the missing piece from the DNA in the founding teams of transformational companies is now the domain expert, who has deep insight into the industry they are trying to disrupt.
I think we will see more innovations in each industry, rather than just technology improvement like the last few decades with Microsoft, Google, Facebook, Apple and Amazon.
In the meantime, our project team in CMU has spent a significant amount of time to produce a quite good report on the Education Innovation.
Many software engineers and IT professionals dream of developing a ‘killer App’ for popular products like the iPhone, which will make them rich. Other people dream of one day having a book published.
Not many achieve either – and even fewer do so in their early 20s. But Vo Duy Khang (formerly student 3184092), an alumnus of RMIT Vietnam’s Bachelor of Information Technology program, has hit the jackpot with success in both of these areas – and now has the makings of a successful business spanning both Vietnam and Australia.
Khang graduated from RMIT Vietnam in November 2010 and travelled to Adelaide, Australia, where he is now completing a Master of Information Technology with Carnegie Mellon University, under a full scholarship.
With the benefit of the scholarship, Khang has been freed up to apply his own financial resources fully to get a small business off the ground while he also continues his studies.
His hard work and talent have been recognised by US publisher Apress, which has just decided to publish a book by Khang on how to build better iPhone applications. Khang’s book, Pro iOS Apps Performance Optimization, fills a need in the market for more practical guidance in this booming area of consumer technology.
Khang’s creativity and expertise has also been applied to a new business start-up in this field which already has five people on staff in Australia. Khang has been visiting Vietnam in the past month seeking further talent from Vietnam to join his operation.
Almost all his development team to date are RMIT students or graduates.
“They speak English well, and they all have a good understanding of what is needed,” Khang says.
According to Khang, the basis of a good user experience of any iPhone or iPad App is good performance. There is enormous potential in helping social networking applications such as Facebook to provide a better user experience by moving data in a quicker and smarter way over the net.
Apress has been impressed by his thinking in this area, as shown on his own website and as shared amongst the online community overseas.
One of Khang’s mentors has been Barend Scholtus, Academic Services Manager for the Bachelor of IT program, and the two continue to discuss shared interests regularly.
“We hope – in fact we are pretty sure – that Khang’s learning experiences at RMIT Vietnam have made contributions to his achievements to date, and we hope the best is yet to come.”
