Going for a run? Share your progress with Google Maps

I’ve done a number of long runs in the past few years, both at Ultramarathon events and in training beforehand. In the online forums for these events people often talk about whether they should hire GPS trackers but I’ve been using the free Location Sharing feature on Google Maps instead as I’m already carrying my phone.

Why Share?

IMG-20190713-WA0012-cropSharing my location with family and friends is a useful way for them to keep track of me. For example if I’m getting collected at the finish, or if a friend who is also running can see I’m just behind them they might slow down for a chat.

In the training runs in particular tracking is also a good safety feature. If I’m not back home when expected then my family can quickly check to see if I’ve stopped (possibly injured) somewhere or if I’m just taking a scenic detour past the beer garden of the Coach and Horses.

Does the battery last?

I’ve found that on my Android phones (currently a Moto G6) I’ve not had any really noticeable impact on battery life when using Location Sharing. If I’m on one of my longer runs (over 6/7 hours) then I’ve usually got a portable USB battery stashed in my running bag with the first aid kit and Jelly Tots anyway. I find that using the camera and screen is more likely to impact the battery life.

How to set it up

This is how I set up Google Maps Location Sharing on my phone. Your experience may differ, but hopefully not by much.

1. Open Google Maps on your phone and tap on your picture on the top right hand corner


2. On the menu, choose “Location sharing”


3. The next screen will show anyone you are already sharing with, Tap the “Add people” button in the top right.


4. You can then set how long you want to share your location for- here it often makes sense to say “Until you turn it off”- if you forget to then Google will email you a reminder periodically over the coming days. Finally either pick contacts to share your location with or choose to share a weblink by email/ WhatsApp etc.


And that’s it. Lace your trainers up and off you go. Just remember to take your phone with you!

Footnote- it’s worth remembering that as with the GPS trackers your position will only be updated when you have data reception The Maps app will however show how long ago the last reading was taken so if you are disappearing off into the wild where there’s no cell coverage your friends might see a “20 minutes ago” note below your icon.

CSS, Javascript, Images cause 500 errors after IIS Website upgrade


A website has been copied from a server running IIS 6 (Windows Server 2008) to a server running IIS 10 (Windows Server 2019). Pages do not render correctly, and further investigation shows that pictures, css files, and javascript are all failing with 500 (Internal Server Error) responses. This is shown here in the F12 view in Chrome.


Trying to access one of these static files directly also fails and just shows the message “The page cannot be displayed because an internal server error has occurred.



In my case, the site was referencing the FontAwesome package which uses the WOFF file type. In the older IIS this MIME type was not registered so required a manual entry in the configuration. In the newer IIS this is handled natively and the manual configuration is now causing a problem rather than remediating one.


Check the web.config file for a reference to “woff” for example

<mimeMap fileExtension=”.woff” mimetype=”application/font-woff” />

and comment out or remove this line.


Refresh the page in your browser and it should now load correctly.

Note Taking at Conferences

When I’m in sessions at conferences I’m often a prolific note-taker. I find the process itself of writing things down has benefit as well as the resulting pages of scribbles. In this post I’ll discuss a few things that work for me, some of which you may want to try yourself.

Paper or Electronic?

startup-593327_1920-pixabayA tricky decision. I do like my paper notebooks, but there are definite advantages in terms of on-the-fly editing, photography, and post-event reference of using an electronic device to take notes. Depending on the event, what I’m carrying, and whether I remembered to recharge my tablet the night before, I will swap between the two quite happily.

When I do take paper notes I try to remember to scan them in afterwards- I use the Microsoft Office Lens tool to get them into OneNote.

When I’m going digital I usually use an Apple iPad Air, Adonit Jot Pro pen, and Microsoft OneNote. I’ve tried a number of different tools here and these work best for me. I’ve found I’m generally too slow at typing to keep up with many presenters, and it’s harder to interleave quick drawings into my notes without the pen device.


If you know in advance what sessions you’re going to be attending (or have a few minutes whilst waiting for the hall to fill up) then it’s good to prepare. On OneNote I often start a new section for the event and a new page for each session I’m attending. The page can be pre-populated with the abstract of the talk copied and pasted from the conference website. This not only helps make sense of what I was scribbling about when I look at it a few months later, but also provides a lot of searchable context on the page.


If you’re using a device with a camera to record notes then taking pictures of any slides can be beneficial to note taking. Most conferences will publish complete slide decks after the event so I don’t worry too much about getting a perfect shot or a complete set, but having key slides included in my notes can be useful.

Sometimes a quick pic of the title slide if it’s up before the session starts can be useful, especially if there’s contact info for the speaker or a link to the slide deck.

At a recent “Microsoft Ignite: The Tour” event most of the presentations included an early slide which covered the structure of the upcoming talk. I took a photo of this and then used these sections to organise my notes during the rest of the session.


If you know the slide deck is going to be available, you can also forgo some of the photos and make a quick note, something like “Great diagram on slide showing this architecture”, and then go back later after the event and look it up.

One small request though- please don’t be one of those people who spends the whole talk waving their phone/ iPad in the air (unless you’re sat on the back row). It can be very distracting for other people in the audience.

A bit of Colour

Whether my notes are on paper or on the screen I like to use different coloured pens and highlighters in my notes. I find it helps make my notes more readable in the aftermath of an event and draws my attention to important points I need to understand or follow up on.

When watching conference sessions, webinars, podcasts, and so on I often get those moments of “ooh, that would be useful in my environment”. These I’ll jot down somewhere on the page and usually highlight or put in a particular coloured box, so I can refer back to them later.


My notes are taken for my own use, but it’s worth considering who your audience is. If you want some great examples of notes designed for public consumption then I’d recommend checking out Barry Coombs’ “Tech Doodles” as something to aspire to.

Hopefully this insight into my note taking has given you some ideas, try them out and remember to do what works for you. Next week (January 2020) I’ll be at Cisco Live Europe, sat in the front row taking notes.

Azure- Why is my OS disk bigger than I asked for?

When spinning up a VM from a marketplace image using the Azure Portal you don’t get a choice of OS disk size, and if you specify a size in an API call it’s ignored. For example when deploying Ubuntu images a 32GB default OS disk is always created.

This is because the size is defined in that marketplace template. We can use the Azure CLI to pull out this information.

az vm image list
returns a list of Marketplace Images. Then:

az vm image show --urn "Canonical:UbuntuServer:18.04-LTS:latest"
 "automaticOsUpgradeProperties": {
    "automaticOsUpgradeSupported": true
 "dataDiskImages": [],
 "hyperVgeneration": "V1",
 "id": "/Subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/Providers/Microsoft.Compute/Locations/westus/Publishers/Canonical/ArtifactTypes/VMImage/Offers/UbuntuServer/Skus/18.04-LTS/Versions/18.04.201911130",
 "location": "westus",
 "name": "18.04.201911130",
 "osDiskImage": {
     "operatingSystem": "Linux",
     "sizeInBytes": 32213303808,
     "sizeInGb": 31
 "plan": null,
 "tags": null

The “sizeInGb” entry shows us that a 31 GB OS disk is part of the template provided by Canonical. Other templates are similar, CentOS is 1GB smaller at 30GB and RHEL is 64GB.

If a smaller OS disk is required then a custom template can be used in place of the Marketplace one, but there’s a certain level of maintenance required to keep that up to date.
