After creating a new user in MariaDB / MySQL, flush permissions and MYSQL_SECURE_INSTALLATION

After installing LAMP on new servers (similar to as described here for CentOS), I’ve recently had two errors after the creation of MySQL users.

These user accounts required additional steps after creation – flushing permissions, and re-running the MySQL secure installation.

DateTime with no DateTimeZone set in PHP.ini with ffmpeg and ClipBucket

I’ve been exploring how to generate videos on the fly through use of packages like ffmpeg (I installed this the other day), and recently tried out ClipBucket (a free video site script).

ClipBucket is a little rough around the edges, but has a load of great features, has a relatively active community, and large parts of the code are on GitHub.

INACCESSIBLE_BOOT_DEVICE, courtesy of Intel Rapid Storage Technology drivers (14.5.0.1081)

Note to self: do not update Intel Rapid Storage Technology drivers on a HP Proliant ML10v2, unless I really, really need to.

I’ve become complacent when throwing drivers at devices and this is a reminder how easy it is to break things. I recently added a TPM to one of my servers and one of the fixed drives is classified as removable by Windows, which means I can’t use the TPM with it. There’s at least two ways to fix this, either install Intel RST drivers and configure it through the console, or change some registry keys to force them to fixed drives.

Mapping UK Highways Agency traffic data in PowerBI Desktop

I downloaded the May 2017 version of PowerBI desktop to load in some of the traffic data that I dropped into Qlik Sense and Tableau in a previous post.

 

The finished article first

 

So – back to getting started. This is my first time using the software, and it’a pleasant experience right up until I try to load an .xls file.

 

A missing driver? Already?

Viewing Department for Transport vehicle statistics by make in Qlik Sense

Generally, getting access to vehicle data is a pay-for-data experience – but snapshots are released each year to the public.

If you head to the Vehicle Statistics page on gov.uk you get statistics about vehicle licencing, excise duty evasion, vehicle roadworthiness testing and more. You’ll probably want to check out the index as there’s 76 files in the 2016 download alone, at various levels of granularity…

The one I’m going to look at today though, is:

Licensed Cars, Motorcycles, Light Goods Vehicles, Heavy Goods Vehicles, Buses and Other vehicles by make and model, Great Britain, annually from 1994, quarterly from 2008 Quarter 3 ; also United Kingdom from 2014 Quarter 4

AKA table VEH0120. Interestingly, Qlik Sense throws an “Unknown Error” message when trying to load “.ods” files so I converted it to Excel prior to loading.

Having a look at UK Highways Agency Traffic flow data – in Tableau Public and Qlik Sense (Cloud)

I’ve had a copy of some of the Highways Agency data downloaded for about a year – so it was time to have a quick look at it.

I’m going to quickly load a single month into Tableau Public and Qlik Sense Cloud (the CSVs are approx 850MB per month) to look at some basic mapped traffic flow information.

The data

The data in this post comes from the Highways Agency journey time and traffic flow data on the data.gov.uk website. Unfortunately this data stops at the start of 2015 (data from then on is incomplete) and is now available via the webtris system APIs, although this post looks at data from March 2012.

Connecting to Google Analytics in Qlik Cloud (Qlik Sense) through the Qlik Web Connectors package

This post looks at using Qlik Cloud (using a paid-for tier) to gather and analyse data from Google Analytics.

Qlik Cloud doesn’t allow user-added extensions, connectors or alterations (unlike the Qlik Sense Desktop and Enterprise products), but is free at the basic tier where you can load from uploaded files. As mentioned, I am using a “Plus” account which gives me access to more connectors.
