Fix video playback from Google Drive on Intel ChromeOS based devices

Since ChromeOS v48, some videos when played back from Google Drive fail at certain points in playback. To get it to start again, you have to reload the page and skip past the section causing the issue.

This has been flagged with the Chromium developer team and is down for a fix in v51. However, as a temporary workaround, in chrome://flags disable "Hardware-accelerated video decode Mac, Windows, Chrome OS" and restart. The videos will then play fine.

This setting has to be changed on a per user basis.

Brief video of changing the flag:

Delete a specific email using GAM

If a user send an inappropriate email to a loads of people or get stung by some sort of email exploit you can quickly delete the email from all of the recipients using a GAM command. Step 1 - get the email header Go into Google Vault and search for the offending user or someone known to have got the message. Click show details and grab the email ID. This will be a long string of characters followed by @mail.gmail.com Step 2 - find out who has the email Go into Google Vault and find the original message sent by the offending user. Look at the details to see who got it. Copy the list and dump it into a spreadsheet. Clean up to just a list of emails with a column header 'mail'. Save as a csv file.

My favorite GAM commands - well a few of them at least!

Where would be without GAM? Paying for expensive syncing tools or doing tedious manual tasks in the admin console. GAM can automate most things you might want to do in G Suite. So these are a few of my favourite commands - one I use either as part of a batch file - or just standalone. There are loads more - but these are ones that are used daily. Classroom Create a spreadsheet of all your domains classes - gam print courses todrive Create a spreadsheet of a teacher's classes: gam print courses teacher fred@mydomain.com todrive Bulk create classes: gam csv classes.csv gam create course alias ~alias name ~alias section ~subject teacher ~teacher status ACTIVE where classes.csv is a list of classes you want to make. Add teachers: gam csv teachers.csv gam course ~alias add teacher ~teacher Add students: gam csv students.csv gam course ~alias add teacher ~student Sync Students (in this example to a group - but could be an ou/csv file) gam csv grou...

Google MDM for Windows 10 Devices - a more in depth look.

In my previous blog post, I gave an overview of Google's new mobile device management for Windows 10 devices. A few weeks in now, we have a number of users using Windows computers managed this way. So below is a more detailed video look at deploying policies followed by some of the policies and how to configure them that we have used to date. Policy Settings It's important to note that unlike ChromeOS devices, you don't put machines into OUs, but the machines pick up policy based on the OU of the user used to enrol the device. OMA-URI policies we use: AllowManualMDMUnenrollment ./Device/Vendor/MSFT/Policy/Config/Experience/AllowManualMDMUnenrollment Integer 0 This prevents users from unenrolling a device. AllowVPN ./Device/Vendor/MSFT/Policy/Config/Settings/AllowVPN Integer 0 Prevents editing the VPN settings PageVisibilityList ./Device/Vendor/MSFT/Policy/Config/Settings/PageVisibilityList string hide:network-vpn Can be used to hide bits of the set...
