20、ountries. This research report delves into key developer trends for Q3 2020 and beyond.The report focuses on six major themes - each with its own visualisations - showing how the data lends insight into the developer community.Developers extra needs due toCOVID-19: Working and performing during a pa

21、ndemic will leave deep marks behind, both financially and psychologically speaking. In this chapter, we explore COVID-19s effects on developers changing needs in relation to their development activities.Language communities - an update: Programming languages are often the kernels of strong communiti

22、es and the subject of opinionated debate. In this chapter, we provide updated estimates of the number of active software developers using each of the major programming languages, across the globe and across all kinds of programmers.Why do developers adopt or reject cloud technologies?: In a world wh

23、ere infrastructure can be provisioned and destroyed at will, and where data and server configurations can be transferred easily between homogeneous systems, cloud providers have to find other areas of differentiation in order to compete. Vendor lock-in is much less of an issue for users than it once

24、 was, and the rise of the developer as a decision-maker has put even more power into their hands. In this chapter, we look at some of the reasons that developers give for adopting or rejecting different cloud technologies and provide insight into why things are as they are.Who is into DevOps?: DevOp

25、s is commonly used as a catch-all term to describe a cultural shift within organisations that enables developers to release software faster and more reliably. However, DevOps is not a single, coherent sector or technology, which often creates confusion as to who is considered a DevOps practitioner.

26、In this chapter, we offer a fresh view on who is into DevOps based on the activities developers are involved in. We also look at the specific roles and software sectors that are most associated with the DevOps culture.What do developers value in open source?: Based on our research, the use of open-s

27、ource software (OSS) is ubiquitous in the global developer community. In this chapter, we explore what exactly developers value in using OSS. We also highlight some uncertainties around the future of the open-source movement by presenting trends across geographic regions and software sectors.Emergin

28、g technologies: As interest in a technology waxes and wanes, so does its influence. The hot topic of yesterday becomes insignificant in the face of new challenges and opportunities. In our surveys, we have tracked engagement with and adoption of emerging technologies for the past two and a half year

29、s. In this chapter, we discuss which technologies have increased and decreased in popularity over the previous twelve months.We hope you will enjoy this report and find the insights useful!

35、rt that they need more flexibility in working hours/workload as a consequence of COVID-19.Collaboration tools and platforms are the most important technical need for developers.Self-employed developers and developers who work for small companies have fewer extra needs due to COVID-19.The larger the

36、company developers work for, the stronger their need for self-management and collaboration tools, as well as for mental health support.Developers responsible for tooling specifications and for approving budgets and expenses are in the greatest need of increased security, performance, and cloud space

37、.Programming language communities an updateJavaScript is the most popular programming language by a wide margin, with 12.4M developers globally using it.Python now counts 9M users, after adding 2.2M net new developers in the past year alone, outranking Java at the beginning 2020.Kotlin is one of the

38、 fastest growing languagecommunities, having increased more than two- fold in size since the end 2017.Why do developers adopt or reject cloud technologies?Pricing and support/documentation dominate developers decision-making process when adopting a cloud technology, but pricing is by far the most im

39、portant reason for rejection.There are lots of opportunities for vendors todifferentiate their orchestration tools in the market - developers are less concerned with price and more with features that help them to develop.Developers arent so concerned with featureset or performance - as long as cloud

40、 solutions meet minimum requirements.Developers will reject technologies that dont provide them with a fulfilling development experience. Having access to a community and adequate support are important.Who is into DevOps?The vast majority of professional developers (more than 80%) are involved in De

41、vOps in one way or another.Continuous integration (CI) and continuous deployment (CD) are two of the most common DevOps practices, but only one in four developers use both to fully automate their workflow.Programmers are very likely to use CI/CD, but not so much operational practices such as monitor

42、ing applications in production environments.With some exceptions, software sectors with high concentrations of experienced professionals are more likely to embrace the DevOps model.What do developers value in open source?Developers appreciate collaborating and interacting with the open-source commun

43、ity more than contributing to open-source projects.Western European developers value almost every aspect of open source more than developers in other regions.South Asian developers highly value contributing to open-source projects, positioning this region to drive the next wave of open-source develo

44、pment.Emerging technologiesEmerging technologies such as AR and VR are not fully engaging OSS principles.Little change in engagement and adoption rates indicate that DevOps has reached maturity.Fog/edge computing is gaining traction amongst developers engaged with the topic, but overall engagement i

45、s low.Computer vision is on the path to maturity, and with a strong pipeline of developers learning about this topic, adoption will continue to rise.Fatigue is setting in for some advanced technologies, but adoption is rising amongst developers who continue to engage.1DEVELOPERS EXTRA NEEDS DUETO CO

46、VID-19Working and performing during a pandemic will leave deep marks behind, both financially and psychologically speaking. In this chapter, we explore COVID-19s effects on developers changing needs in relation to their developmentactivities.At the time of writing this chapter, there have been more

47、than 30 million COVID-19 cases around the world, with 7.3 million of those still active. The virus is ubiquitous and affects all continents to more or less similar degrees. Working and performing during a pandemic is an experience that will undoubtedly leave deep marks behind, both financially and p

48、sychologically speaking. In this edition of our State of the Developer Nation report, we explore COVID-19s effects on developers changing needs in relation to their development activities.Flexibility in working hours and workload is the most pressing COVID-related need% of developers (Q3 2020 n=16,1

50、l needs9%Hardware components / machines9%Increased security options7%More cloud space7.2 MILLION DEVELOPERSREPORT NEEDING FLEXIBLE WORKING HOURS/WORKLOADWe asked respondents to select from a given set of technical and non-technical needs, up to three extra needs the pandemic has created for their ow

51、n development activities. 73% of developers reported having additional needs due to COVID-19. In particular, 34%, or 7.2 million developers, expressed their need for flexible working hours/workload.Quarantine and social distancing policies have encouraged many employers to allow their workers to wor

52、k from home, where possible. A large proportion of workers are now facing the inconvenience of relocating their working space into their home. Among such inconveniences is the necessity of taking care of households while keeping up productivity. Under these circumstances, flexibility is seen as the

53、key to success, or simply survival.The next most common perceived needs, reported by about one in four developers, are: collaboration tools and platforms (26%), online training resources (25%), and virtual opportunities to support networking and peer-to-peer interaction (23%). Among these three, the

54、 only technical one, strictly speaking, refers to the need for collaboration tools, such as video conferencing platforms.The other top needs are related to self-improvement and self-management, and to socialising.The supremacy of non-technical needs is striking. All of the technical necessities, exc

55、ept collaboration tools, sit at the bottom of the list, being reported only by about one in ten developers: better performance in terms of computing resources (13%), hardware components (9%), increased security (9%), and additional cloud space (7%). There are two explanations for these patterns. Fir

56、st, developers may have not indicated the need for extra technical support because it had been already fulfilled, i.e. their employers had already provided them with it. It could also be, however, that developers did not perceive technical considerations as being more important than flexibility, net

57、working, and learning.The bigger the company, the more flexibility is needed% of developers, (Q3 2020 n=11,690)50%Flexible working hours/workload45%40%35% Collaborationtools and platforms30%25% No extra needs20%15%10%Mental health support5%Just me2-56-2021-5051-100101-500501-1,0001,001-5,00010,000+0

58、%5,001-10,000Number of employeesWe ran a random forest model and found that the most important factor in influencing developers needs in relation to COVID-19 is their company size. Compared to those in middle- or large-sized companies, self-employed developers and developers working in small busines

59、ses of up to 20 employees report fewer new needs overall. That is especially the case for flexibility in terms of working hours/workload, and for collaboration tools. The most probable explanation is that they would have already implemented a flexible working schedule prior to COVID-19. This is like

60、ly to apply to contractors as well as to small, dynamic startups. When it comes to keeping collaboration and interaction going, it may just be easier for small groups of people to maintain old habits or find an easy-to-use tool, such as emailing, phoning, or even getting together whilst respecting t
