Web browsers have been updated; but the server administrators are left alone: For stability reasons, many run long-term support editions such as Ubuntu 12.04 LTS. Even without that, most will stick to the reliability of Apache 2.2, hesitant […]
Security is hard. Security that works with a variety of platforms under a flurry of circumstances with an endless choice of applications is practically impossible. SSL and TLS, the Internet security workhorses, try to achieve this feat … and fail from time to time. While some software has been updated, not all of it has. […]
Time Machine backups to a Linux machine running Netatalk is a very convenient way of safeguarding your data. However, the I/O load on the server machine can sometimes become very high. Here is a quick hack to improve this, if you need AppleTalk AFP services mostly for TimeMachine.
