Colin Charles: 3 Big Announcements from MariaDB (my take for Oct 2015)

Tue, 2015-10-27 03:25

Today I received about five emails with the subject: 3 Big Announcements from MariaDB. Maybe you did as well (else, read it online). October has brought on some very interest announcements, and I think my priority for the big announcements vary a little:

  1. MariaDB Server is now available on Amazon RDS – you wouldn’t believe how many people ask for this, as many now deploy using Amazon Web Services (AWS), so now that it is available, I consider this to be extremely amazing. You get 10.0.17 today, and within 3-5 months of a GA, you get the next release (the docs are a work of art — read them!).
  2. MariaDB Server 10.1 is now a stable GA — this is a milestone. Our last stable GA came out in March 2014. There are plenty of new features and we had a developer meeting to plan what comes in 10.2 as well. Remember to read: What is MariaDB 10.1?
  3. New XAMPP with MariaDB — The new XAMPP does not ship with MySQL any longer but MariaDB Server 10.0.17. This is going to help distribution tremendously as many people use XAMPP as a development environment (it is after all the most popular PHP development environment out there). Remember to get your downloads for Windows/Linux/OSX. 

I think the above are my highlights of 3 big announcements from the MariaDB world. What are you waiting for, download it now! And remember to report bugs/feature requests to our Jira instance.

Ben Martin: ESP8266 and a few pins

Mon, 2015-10-26 23:41
The new Arduino 1.6.x IDE makes it fairly simple to use the ESP8266 modules. I have been meaning to play around with a some open window detectors for a while now. I notice two dedicated GPIO pins on the ESP8266, which is one more than I really need. So I threw in an led which turns on when the window is open. Nothing like local, direct feedback that the device has detected the state of affairs. The reed switch is attached on an interrupt so as soon as the magnet gets too far away the light shines.

I will probably fold and make the interrupt set a flag so that the main loop can perform an http GET to tell the server as soon as it knows when a state has changed.

Probably the main annoying thing I've still got is that during boot it seems the state of both the gpio pins matters. So if the reed switch is closed when you first spply power then the esp goes into some stall state.

It will be interesting to see how easy OTA firmware updates are for the device.
