Feed: Planet big data. Author: Josh Zelonis. Motherboard and Kaspersky unveiled that hackers compromised a server of computer manufacturer ASUS’s live software update tool to install a malicious backdoor on thousands of computers. The malicious file was able to masquerade as an authentic software update as it was signed with legitimate ASUS digital certificates. The manufacturer unwittingly pushed out the backdoor to customers for at least five months before its discovery last year. At Forrester, we have been tracking this dangerous trend in which cybercriminals use compromised update servers to distribute malware, a trend that has already affected Arch Linux, ... Read More

Feed: Blog – ArangoDB. Author: Willi Goesgens. This is an update of the 2016 blog post How to put ArangoDB to Spartan-Mode. A lot of things have changed in the last years. We moved our API implementation from JavaScript to C++. ArangoDB now has a new (default) storage engine, namely RocksDB instead of MMFiles. RocksDB is a great storage engine. However, it also trades memory for speed. If you start with the default configuration you might end up with using much more memory for ArangoDB than expected. Therefore let’s focus on our new storage engine, and make a configuration to ... Read More
