You wouldn’t expect a sequence select to be a significant problem but recently we saw that it was—and in two different ways. The issue came to light when investigating a report performance issue on an Oracle 11.2.0.4 non-RAC database.

This year, The PostgreSQL Global Development Group released PostgreSQL 9.4, which was equipped with several bug fixes as well as a few new capabilities, such as:

Yes, SMBs should pay attention to disaster recovery

Effective disaster recovery plans admittedly take a lot of time, resources and attention to develop, which may cause some small and mid-sized businesses to stray away from the practice. While it's easy to think "it could never happen to me," that's certainly not a good mindset to possess. 

Linux users may need experts to reinforce malware detection functions

Enterprises using Linux operating systems to run servers or desktops may want to consider hiring specialists to prevent actions initiated by the "less" command.
