Open source code has fewer defects per thousand lines of code than proprietary software, according to the 2011 Scan Open Source Integrity Report from the U.S. Department of Homeland Security and Coverity. "The line between open source and proprietary software will continue to blur over time as open source is further cemented in the modern software supply chain," says Coverity's Zack Samocha. The 2011 report analyzed more than 37 million lines of open source software code and more than 300 million lines of proprietary software code from a sample of anonymous Coverity users. Coverity says it used a testing platform that was upgraded this year with the ability to find more new and existing types of defects in software code. The report notes that for open source projects, which have an average project size of 832,000 lines of code, the average number of defects per thousand lines of code was .45. For example, Linux 2.6, PHP 5.3, and PostgreSQL 9.1 had defect densities of .62, .20, and .21, respectively. However, the report found that in propriety codebases, which averaged 7.5 million lines of code, the average defect density was .64.

پکیج تصفیه فاضلاب لبنی به مجموعه از تجهیزات و دستگاه های مختلف گفته میشود که به منظور کاهش آلاینده های جامد و محلول در مراحل مختلف تولید لبنیات استفاده میشوند. در واقع، با این پکیج ها تمام مراحل تصفیه در یک مجموعه و مخزن انجام شده و موادی از قبیل چربی، ذرات پنیر و غیره معلق، یون ها و غیره را از بین میبرند.
ReplyDeleteThis is an interesting article. I think open source code has an advantage over proprietary code when it comes to quality because people from all around the world can make contributions and give feedback. Open source code is also constantly being updated, which means it is less likely to have bugs or technical issues. Open source is the way of the future and I'm glad to see that it is gaining traction and recognition for its quality.
ReplyDeleteIn the realm of coding, Open Source triumphs over proprietary code in quality. Its collaborative nature fosters innovation and peer review, resulting in reliable, secure, and efficient software solutions. Embracing Open Source ensures high-quality code, empowering developers and users alike with superior technology
