Scylla and Elasticsearch - Over on ScyllaDB's blog, a posting on using Scylla and Elasticsearch side by side. A Node.js app uses Scylla as the database of record and Elasticsearch to analyze the content of Tweets.
Cassandra - A look at Cassandra and Time Series data models sheds light on how partitioning and bucketing data, along with compaction strategies can help cope with massive amounts of data by spreading it further around a cluster.
PostgreSQL 10 - One of the big features of PostgreSQL 10 is the native partitioning support. In a blog post on postgrespro.co.il, they take it for a spin and show how you can use ranges to partition records easily and what kind of impact it has on performance.
- RHEL 7.4 - Redhat have updated their Redhat Enterprise Linux to version 7.4. Headline changes include new security features, performance enhancements and more architectures supported. It also sees the quiet end of the Btrfs, which was introduced as a technology preview some years back and never got beyond there and is now deprecated after a last update - expect it gone in RHEL 8.
Passwords - Want a previously pwned password? Troy Hunt has a collection of, now, 320 million of them free to download for your protective pleasure. The idea is to test passwords against this pool of clear text and SHA1 hashes to ensure that it's not a previously cracked password.
nmap - Talking about passwords, the new nmap 7.60 just got support for brute force SSH password cracking, using known credentials and probing for authentication methods and what public keys they'll accept. So expect more knocking on your SSH ports looking for a way in during the rest of the year.
- Back to the Future Java brings the Java VM to 8-bit systems like the Commodore 64. Based on the Logo Mindstorms JVM leJOS, it offers an interestingly challenged VM running threads on a classic 6502 machine.
