Do you know that there is a hidden feature in Mac OSX which allows you to view information of all printers added on your Mac? Last week I was looking for a way to know the IP address of a network printer which I added a long time ago but I could not know how to do that. I found a very simple solution which seemed to be interesting to me.

You first need to run the following command:

sudo cupsctl WebInterface=yes

After running, you will be able to browse to a web page which lists all printers in your Mac. The website is always at the address: http://localhost:631/admin

For me, this is an interesting feature and I think it might be helpful for you to know.

Introduction

Recently I published a blog post about the new GIS features in MySQL 5.7. Today I’ve looked into how to use MongoDB (I’ve tested with 3.0 and 3.2, with 3.2 being much faster) for the same purpose.

This blog will discuss some recent developments with MySQL document store.

Starting MySQL 5.7.12, MySQL can be used as a real document store. This is great news!

In this blog post, I am going to look into the history-making MySQL work better for “NoSQL” workloads and more of the details on what MySQL document store offers at this point.

One of our customers recently ran into a problem, where he wanted to have a preferred donor for SST, whenever a node came up. The problem was, that the node did not come up, when the preferred donor was not running.

In the documentation, you can find the parameter wsrep_sst_donor, which prefers the specified node as SST donor. This is great, as long as the donor is actually running.

The problem can be fixed by adding a comma to the end of the value of wsrep_sst_donor, what would look like this:

wsrep_sst_donor="galera2,"

Note the comma at the end of the value. This trailing comma basically tells this node, that galera2 is the preferred donor, if galera2 is not available, any other available node will be used as donor.
