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.

IT Blog Award Winner

Wow.

Thanks to all those that voted for “IT Should Just Work” in the IT Blog Awards and passed the devious maths test at the bottom of the voting form. I’m shocked and humbled to let you all know that the results are in and this blog won the award for Best Analysis. It’s surprised me, and the flurry of social media activity through the weekend following the announcement has shown there’s some big winners in the other categories.

Cisco Blog Awards Winner

I’d recommend anyone reading this visits the IT Blog Awards page and checks out the other winning blogs. Congratulations all!

To quote the list:

Thanks again- it’s always good to know that someone reads what I write and (hopefully) finds it useful or informative.

IT Blog Awards

I’m pleased to announce this blog is a finalist in the 2018 IT Blog Awards hosted by Cisco in the category of “Best Analysis”. Voting is open to the tech community through January 4th 2019, so if you’ve found this blog useful or insightful at any point (or you’ve followed my advice and your datacentre didn’t catch fire as a result) please can you go to http://cs.co/itblogawards and pop in a vote for “IT Should Just Work” in the first section.

If you don’t want to vote for this blog, that’s fair enough, but I’d still recommend having a look at the voting form if only for the awesome “I’m not a bot” section at the bottom.

Thanks!

vSAN Licensing: Expanding Clusters and Setting off Alerts

vSAN licenses are assigned per-cluster, so whilst the total number of vSAN licenses in a vCenter inventory might match the total number of vSAN host CPUs, they may not be assigned correctly to the clusters. This will trigger the critical vCenter alarm “License inventory monitoring”. This will also occur if a cluster is expanded (e.g. additional hosts and vSAN licenses are purchased) as it’s only possible to assign one license key to each cluster.

In the example screenshot here we have 2 vSAN license keys, each valid for 8 CPU. The total 16 CPU capacity matches the 16 CPU in use. However, one cluster has 10 CPUs (i.e. 5 dual socket hosts) and the other only 6 CPU. Therefore one license key is 2 CPU oversubscribed whilst the other has 2 free.

The method to resolve this is to use the MyVMware license portal to split and merge your pool of vSAN licenses until you have license keys where the capacities match your cluster sizes, and then re-license the vSAN environment. This VMware KB article explains in detail how to do this divide, and merging is a similar process on the same interface: https://kb.vmware.com/s/article/2006972

In the example screenshot above, this was a case of splitting one of the 8 CPUs into a 6 and a 2, and then merging that 2 with the remaining 8 CPU key to create a 10 CPU key and a 6 CPU key which matched the cluster sizes. The old 8-CPU key that was split was removed from the license inventory.
