Ubuntu and new PostgreSQL10

PostgreSQL10 is a new milestone in SQL databases. First - it supports Blockchain characteristics out of the box: All data is automatically replicated across a wide cluster of PostgreSQL servers. Unlike MongoDB, CouchDB, RethinkDB - fully ACID!!!! - At the same time: "voting" is introduced - a cluster insert is counted as 'committed', when the majority of PostgreSQL10 servers are answering "physically stored".

Second: Clients now do not connect to one PostgreSQL server any longer. They connect to a cluster of PostgreSQL servers and get automatically informed, when a new machine is added to the cluster. This way, you have a 'perfect scale-out' of read performance.

Third: PostgreSQL now allows seamless table and database split, sharding and automatic copying to a dedicated or standy cluster of servers for e.g. OLTP or OLAP processing, long running SQL scripts.

Fourth: PostgreSQL10 now also is a document database. Use with JSONB to take full advantage of fulltext hash search in documents.

Last: It stays a normal PostgreSQL server with triggers, (Oracle compatible) server side scripts, full Python integration server side. But it's 3x times faster now, even on a single machine. In a cluster, you can have 1000x scale-out of PostgreSQL performance now. Simply add new hardware. PostgreSQL10 is automatically doing the rest for you!

My personal recommendation: $50 Odroid HC1 machine with 64 bit 8 core ARM CPU, 2 GByte of RAM, GBit and - SATA!! 9 times faster than Raspberry Pi 3.

Get uptime alerts in Telegram
You will be configuring 3 services. The assumption is that you have accounts already for these services. UptimeRobot — source of the uptime/downtime notifications. It currently supports email, Twitter, Slack, Pushover, Pushbullet and others but not Telegram...

This news tidbit got overshadowed by Amazon Go but still worth looking at.

"It's worth taking a moment to note how using Chromecast differs from using Bluetooth or Apple's AirPlay technology. Once you send music to your Chromecast Audio, the device is reaching out to the internet directly and pulling the music down, rather than streaming to your phone and being bounced over to your speakers. That means that once you start casting music, you're free to do anything you want with your phone and not worry about interrupting the tunes."

The ZigBee signal range of the new square-shaped Hue bridge is approximately 30m (range can vary depending on obstacles in-between the bridge and the nearest light). This range is similar as the old Hue bridge. In order to extend the signal range of the system, each Hue light acts like a range extender by relaying the ZigBee signal.
