导语：现在科技公司发力，开启程序比赛，希望开发出追踪软件，症状筛查app, 一起来学习下
With much of the world under orders to stay at home, would-be volunteers have had a tricky time joining the fight against covid-19. Programmers, however, need not leave their desks. Many are participating in coding competitions (called hackathons) intended to build digital solutions to combat the pandemic’s effects. #BuildforCOVID19 Global Online Hackathon, which was sponsored by Facebook, Microsoft and numerous other tech companies, received over 1,500 submissions from contestants in 175 countries last month. Its top projects included contact-tracing apps, online symptom-screening platforms and tools to help teachers work better with students remotely. CODE19, a hackathon targeted at battling the outbreak in India, will announce its winners this month. Its leading teams could receive serious money to help further develop their ideas: the contest is promising prizes of up to $10,000 for the best projects. More good ideas are on the way: at least a dozen other covid-themed hackathons are scheduled.
随着全球很多地区都处于居家令下，想要做志愿者去抗击新冠肺炎已经是一件很难得事儿了。然而，程序员们不需要离开他们的桌子。很多程序员都在参加解码比赛，这个比赛目的是建立能够对抗流行病影响的电子解决方式。由脸书，微软以及很多其他科技公司发起的代号为新冠肺炎全球线上解码竞赛上个月收到来自175个国家的参赛者超过1500份提交的(项目)。 这其中顶尖的的项目包括接触痕迹应用，网上症状筛查平台以及帮助教师更好的远程教学的工具。CODE19目标是抗击印度的疫情，在这个月其会宣布获胜者。获胜团队可以获得一大笔钱帮助他们进一步深化创意。这次比赛承诺高达1万美金的奖励给最好的项目。更多更好的想法还在陆续不断的产生，至少一些其他的新冠肺炎主题的解码比赛已经提上日程了。
