[Software development big bang, development tool Qt missed by Nokia is ushering in the era of intelligent manufacturing] The first public preview of the software development tool Qt was launched in 1995 and was acquired by Nokia in 2008. From 2011 to 2012, Nokia sold Qt software business to Finnish IT service company Digia after Nokia fully turned to Microsoft; Qt listed in Finland after independence from Digita; 15 million euro investment in 2017; 20 years in 2018 After that, Qt finally ushered in the Internet of Things, especially smart cars, smart manufacturing and other outlets.
As a complete, cross-platform C++ graphical user interface application development framework, Qt not only has a long history, but also has its unique value. C++ is one of the top ten most popular programming languages ​​in the world. It has been more than 35 years old and supports application development from servers to desktops to various embedded devices. Qt's support for C++ has also experienced more than 20 years of development. Extensive support for operating systems such as Linux, Unix, Windows, MacOS, Android, iOS, and embedded VxWorks, including customers of the European Space Agency, Panasonic, Samsung, EA, AMD, Tableau, Tesla, and other well-known software Skype, WPSOffice, AutodeskMaya, LinuxKDE and others are based on Qt development. Qt has more than 1 million developers in more than 70 industries including energy, automotive, medical, military, and industrial automation.
In the current era of software development big bang, Qt's biggest advantage is that it can compile and deploy on any operating system and hardware, as well as graphic interface development, with only one code written once, and it now extends to mobile and embedded device development. It takes only one code to compile and deploy on any operating system and hardware. It is of great value to commercial software companies. Qt is the mainstream graphical interface development environment for Linux and embedded operating systems. In addition, it was already in the Nokia era. Almost all preparations for mobile development for Qt.
On April 17, 2018, Juhapekka Niemi, Executive Vice President of Global Sales and Business Development of Qt Corporation, and Dong Renyuan, General Manager of Qt Greater China, shared with the author on the eve of Beijing Motor Show the Qt company's golden era of software development.
1 Software Development Big Bang
More than 20 years ago, two young developers, HaavardNord and EirikChambe-Eng, sat on a bench in a Norwegian park to discuss a problem. They wanted to build a single frame that could run on multiple platforms as a user interface for ultrasound equipment. This is The beginning of Qt. Connecting a creative world with a language is the original idea of ​​Qt, and it is also the direction that we have been adhering to. In today's software development explosion, the value of Qt has begun to highlight.
In 2011, when Nokia was busy with Microsoft and was about to abandon Qt, Netscape founder and Silicon Valley's famous investor Marc Andreessen published an article in the Wall Street Journal entitled "Software is engulfing the world." In the article, Marc points out: The computer revolution 60 years ago, the invention of microprocessors 40 years ago, and the rise of the Internet 20 years ago, all these technologies eventually changed all industries through software; With the huge market demand for network services, the global economy will be digitized for the first time.
Seven years later, the global digital economy has entered a period of large-scale development. The Digital China Construction Development Report (2017) was recently released at the first Digital China Construction Summit. The report pointed out that China’s digital economy in 2017 reached 27.2 trillion yuan, an increase of 20.3% year-on-year, accounting for 32.9% of GDP. The digital economy ranks second in the world. Whether it is the global or the Chinese market, software is engulfing the world. In particular, with the proliferation of Internet of Things devices, touch screen control has become the mainstream of human-computer interaction from dashboards for automobiles to smart watches to all types of robots.
However, just as what Marc Andreessen experienced seven years ago, he said at the time: "Every company I've worked on has absolutely no talent." Considering that Marc worked for companies that focused on software and network services, the shortage of software development talent was already evident at the time and today it has become a global challenge. Juhapekka Niemi said that with the rapid development of connected devices and IoT devices, the number of graduates engaged in software development is far from enough, and there is a great lack of software development capabilities. Qt is solved through a set of cross-platform solutions. this problem. Today's Qt can run on 12 operating systems, especially VxWorks, which is commonly used in the industrial and military industry. The supported devices can be as large as ship navigation, or as small as IoT devices without a screen, and Qt is constantly developing. Provide a large number of libraries to support native applications. "No one competitor's software has such a wide range of applications as Qt," Juhapekka Niemi stressed.
Dong Renyuan stated that China’s digitalization process has opened Qt to the golden age in China. The development of smart manufacturing and industrial 4.0 requires embedded touch screens in industrial automation equipment, and Qt's opening of its software source code satisfies the Chinese government's autonomous and controllable requirements. Industrial control is the main industry of Qt. In fact, it is basically Qt in the field of industrial control. Next, in many industries, Qt is focusing on expanding the automotive industry, and China is an important market for smart cars and Internet cars.
2 Smart cars are the next battlefield for software
In Marc's article, he specifically mentioned the software revolution for the car. At that time, he proposed that the development trend toward hybrid and electric vehicles will accelerate the transition to software, in which electric vehicles are completely controlled by computers. At that time, Google and some important car companies were already developing software-driven driverless cars.
A McKinsey report in the early 2018, "The traditional car companies are facing a digital subversion of travel," pointed out that the decisive factor in buying a car 20 years ago was the driving experience, and today it has become an in-car experience - for autonomous driving, The need for in-vehicle connectivity, electrification, and sharing, such as self-driving cars, connected parking services, OTA upgrades, cyber security, and more. In order to better enhance the in-car experience, the automotive industry needs to shift its focus from the original hardware driver to the software driver. McKinsey predicts that the software part of the car will account for 30% of the vehicles in 2030. The proportion is substantially higher than the current 10%.
In another April 2018 report, McKinsey predicted that China is likely to become the world's largest auto-driving market in the future. By 2030, auto-driving-related sales of new cars and travel services will generate more than 500 billion U.S. dollars. Up to now, the development of traditional auto parts and the design and branding of autos are the focus of automakers. However, after autopilot dominates in the future, a whole set of new technologies and new skills will be crucial. In the future, the value chain of autopilot will be the highest. The three important capabilities are automated driving software development, autopilot hardware production, and autopilot system integration.
Juhapekka Niemi said that the automotive industry is a typical example of digital transformation and digital transformation. Digitization is leading the entire automotive industry to autonomous driving, creating a shared-based business model, and enhancing personalized in-vehicle experiences such as multi-screen interaction in the car and interaction with mobile devices. In addition, with the hot car companies in Internet companies, the rapid iterative thinking of Internet products has also been brought into the automotive industry. In the dashboard, car entertainment systems, human-vehicle interaction and other aspects require rapid iterative, rapid market.
In this process, the software development platform and user interaction interface play a crucial role. Previously, Qt had launched QtforApplicationDevelopment for workstations and mobile application development, and QtforDeviceCreation for embedded system development. For the automotive industry, Qt specifically launched the QtAutomotiveSuite suite, which has now been upgraded to QtAutomotiveSuite version 2.0. For graphic user interface design, Qt has introduced the 3D graphic interactive interface design tool Qt3DStudio for the automotive industry, allowing developers to easily design various 3D scenes for automobiles.
In 2016, Qt found that the digital software development of automobiles met three major challenges: first, there were more and more digital displays in the car, and developing a unified multi-screen digital user experience was very difficult, because different Automobile manufacturers will have different software development vendors, and different software developers will use different development tools and technologies. In the end, integration will inevitably encounter HMI changes to ensure that all digital screens in the car are The brand unity of the dashboard; Second, the reuse rate of the code is very low. Different projects and different vendors are repetitively developing the code. This is particularly reflected in the development of the car entertainment system, resulting in rapid innovation and differentiation. Difficult, long development cycle and expensive; Third, the original vehicle-mounted system is tightly coupled together, HVAC control, media player, radio and other functions are superimposed on a software stack, especially because of a function of the problem caused a chain reaction, also It is difficult to split the entire system into small projects for parallel development, but also to maintain a large code base, An update of a function requires the entire system to be rebuilt and installed.
Juhapekka Niemi said that more and more automakers have chosen Qt as the software development platform for dashboards and central control vehicles. In 2017, Qt is working with major automakers around the world to develop a concept car based on Qt technology. For example, Qt can control navigation and entertainment systems through in-vehicle controls or sound. In February 2018, QtAutomotiveSuite2.0 was released, adding a lot of new features, including the new Qt3DStudio, QtSafeRenderer, etc. Especially the upgraded NeptuneUI HMI design enables the carload application to load faster and experience better. After QtAutomotiveSuite2.0, Qt will also provide a new UX user experience design. SystemUI can manage applications like a mobile desktop. This makes the future self-driving car, like a walking iPhone, have a very high user experience.
3 Write about the future with Qt
Every year, Qt companies do user surveys. In the latest 2017Qt user survey, Qt was applied to everything from desktop development to mobile applications to embedded systems and headless devices. It involves software development, enterprise applications, and game development tools in more than 70 areas and industries. Robots, smart homes and factories, test and measurement systems, consumer devices, automobiles, medical laboratory equipment, security systems, digital television, etc., Qt are used on land, water, and even space.
Qt software has a commercial version and an open source version. Qt has more than 300 employees in ten countries including Finland, China, the United States, and Japan. It provides custom-developed software functions and professional services for Qt Business Edition to ensure the stability and reliability of software development. Sex and safety. Qt Global's more than one million developers are also the technical resources of Qt products. These developers are constantly pointing out Qt framework issues, optimization and development direction, and even directly contribute code. A user wrote in the 2017Qt user survey: "I feel that there is an entire team of software engineers working for me!"
The voice from the 2017Qt user survey also included: "Qt was able to use a set of code libraries to adapt to multiple platforms, which made my customers very excited each time"; "The large car manufacturers are very satisfied with the results of Qt delivery, they often will Q: 'Is Qt doing this?' 'We can simply migrate the C++ code base that has been accumulated for more than 20 years from MFC to Qt, improving the efficiency of the development process'; 'Qt won't lock me into a technology On the platform, I have great flexibility"; "Qt provides users with a complete web browser/HTML5 experience"; "Synchronized development on Windows/Mac platform"; "Simple and concise API, using Qt is very interesting !";and many more.
Dong Renyuan said that China is Qt's fastest-growing global business region, thanks to China's vast Qt user base, Qt downloads, and the largest software installations in the world. China has many Qt-developed sites. Many people use Qt from the student days. In fact, more than 40% of Qt downloads in the Chinese market come from students from major domestic universities.
Qt continued to invest in China in 2017, increased its sales and service team, focused on specific industries such as automotive, industrial automation, and defense technology, and continued to expand channels, recruit technology partners, and build a sound ecosystem. Qt is also investing resources to help partners quickly enter the market and develop software. Qt is also accelerating the industrial layout, including providing customized solutions for customers such as automotive and industrial automation. Dong Renyuan introduced Qt's research and development to provide digital cockpit skinning and theme-changing solutions that are demanded by Chinese market users.
With the motorization, intelligence, and networking of automobiles, the digital experience of users is becoming more and more important for the automotive industry. The digital experience is not limited to in-car devices. As a new mobile terminal or IOT device, the car will become more and more important for seamless connection and interaction with other mobile terminal devices such as mobile phones and tablets. Connecting different devices to deploy applications on different platforms is the advantage of using Qt for software development. This huge commercial market will undoubtedly become a huge opportunity for Qt, coupled with smart manufacturing and industrial automation that China is vigorously advancing. In an era of software engulfing everything, Qt missed by Nokia will usher in its golden age.
