OpenBSD创始人Theo de Raadt创建了OpenSSL分支LibreSSL，在解释另起炉灶而不是帮助改进OpenSSL的原因时，他说OpenSSL现有的代码一团糟，“我们的团队在一周内从OpenSSL源码树移除了半数代码，都是一些应该丢弃的东西。”他进一步说，开源开发模式所仰仗的是人们能阅读代码，而代码必须清晰。OpenSSL的代码库一点都不清晰，因为他们的社区不关心代码是否清晰。这儿存在文化代沟。他指出，OpenSSL的源码中包含了大量过时的代码，如数千行VMS支持代码，数千行WIN32支持代码，数千行弱化加密的FIPS支持代码。De Raadt说他的团队移除了9万行代码，但剩余的代码仍然具有完整的API兼容。OpenSSL软件基金会主席Steve Marquess拒绝评论分支LibreSSL，称他还没有机会了解这个项目，所以无法置评。Marquess说，OpenSSL一直苦恼于无法获得经济资助和代码贡献，许多财富1000强企业大量使用OpenSSL代码，但却从来没有想过回报项目。

Seeing Deeper: The Webb Space Telescope
The James Webb Space Telescope is NASA's next orbiting observatory and the successor to the Hubble Space Telescope. A tennis court-sized telescope orbiting far beyond Earth's moon, Webb will detect infrared radiation and be capable of seeing in that wavelength as well as Hubble sees in visible light.
Infrared vision is vital to our understanding of the universe. The furthest objects we can detect are seen in infrared light, cooler objects that would otherwise be invisible emit infrared, and infrared light pierces clouds of dust, allowing us to see into their depths. Webb will unleash a torrent of new discoveries, opening the door to a part of the universe that has just begun to take shape under humanity's observations.
Right now, scientists and engineers are piecing Webb together, creating through cutting-edge technology an innovative observatory that not only withstands intense cold, but uses it to its advantage; an observatory that folds up inside a rocket for launch and unfurls like a butterfly opening its wings upon nearing its orbit. Later this decade, the Webb telescope will launch into space, sailing to the distant, isolated orbit where it will begin its quest. Supernovae and black holes, baby galaxies and planets' potential for supporting life — Webb will help reveal the answers to some of the biggest mysteries of astronomy.
The James Webb Space Telescope (JWST) is a large 6.5 meter space telescope. JWST is optimized to study infrared light from the Universe with four sensitive imaging and spectroscopic instruments. JWST's science goals include answering some of our most fundamental questions about the origin of the cosmos and life in the Universe. The telescope is being built by Northrop Grumman Aerospace Systems for NASA, ESA, and CSA. JWST development is led by NASA's Goddard Space Flight Center. The Space Telescope Science Institute (STScI) is the Science and Operations Center (S&OC) for the JWST. The observatory has been named after NASA's second administrator James Webb, best known for his leadership of the Apollo missions.
