expand AWS EC2 FreeBSD ZFS disk

1 Reply

For testing purpose, I setup a Freebsd instance on AWS, which is using zfs on root.
And then I add 10G disk space to the root volume. Even though I enabled auto-expand for zroot, it seems the 10G space is not added to system. Here are the steps to expand the disk for zroot:

1. Reboot the server.  Even though it’s said that reboot is not necessary, I suggest to reboot the server to make sure server can recognize the new size.

2. As the disk size change, we need to fix the GPT partition table first.

gpart recovery ada0

3. Some documents said can use “zpool online -e” to expand the disk. As shown in above picture, the command can’t auto update GPT and assign the space to zfs partition.

4. We need to use gpart to update GPT first, then expand the zfs partition.

#gpart resize -i 2 ada0
#zpool online -e zrrot /dev/adap2

Customize Office 365 Home installation

Leave a reply

I just switched from Office2019 retail to Office 365 Home edition.
And we also can’t choose which office program to install, which means by default access/outlook will be installed on my computer and OneNote will not be installed.

And I checked MS document (https://support.office.com/en-us/article/product-ids-that-are-supported-by-the-office-deployment-tool-for-click-to-run-77654e77-aaeb-4ed6-84eb-1d8b0e086590), it seems we can also use Office Deployment Tool to customize Office 365 Home/Personal installation.

1, go to https://config.office.com to generate a configuration file for installation. For Office Suites, you can choose Office365 Proplus, and we’ll change it after the configuration file is generated.
2, select the Apps you want to install.
3. For the update channel, select “Monthly”
4. Answer the rest questions
5. Click export to download the XML file.
6. Open the XML file, change prodouctID from O365ProPlusRetail to O365HomePremRetail or O365PersonalRetail.
7. Download office deployment tool from https://www.microsoft.com/en-us/download/details.aspx?id=49117
8, open command line, run

setup.exe /configure Configuration_home.xml

Done!

And below are my configuration files, you can use it if you want.

<Configuration>
  <Add OfficeClientEdition="64" Channel="Monthly" ForceUpgrade="TRUE">
    <Product ID="O365HomePremRetail">
      <Language ID="en-us" />
      <ExcludeApp ID="Access" />
      <ExcludeApp ID="Groove" />
      <ExcludeApp ID="Lync" />
      <ExcludeApp ID="OneDrive" />
      <ExcludeApp ID="Outlook" />
      <ExcludeApp ID="Publisher" />
    </Product>
  </Add>
  <Property Name="SharedComputerLicensing" Value="0" />
  <Property Name="PinIconsToTaskbar" Value="TRUE" />
  <Property Name="SCLCacheOverride" Value="0" />
  <Updates Enabled="TRUE" />

fix new iphone can’t sync with outlook.com issue

Leave a reply

It seems Microsoft is encourage people to use the app outlook. The app is good, but I still need to sync the contact between my iphone and outlook to get my contacts number.
Spent some time to check this issue, here is the fix:

    Login to outlook.live.com
    In the browser, click on Settings icon (gear at top right) ; scroll down the Quick Settings panel and click on 'View all Outlook settings'
    In the pop-up window, select 'General'; 'Mobile Devices'
    Select the iPhone, note if you have more than one iPhone (e.g. an older device), select the 'Edit' icon (pencil) to check the details including the version, 'OK' to exit details
    Click on the 'Delete' icon (bin) to remove the device
    Power off the iPhone
    Power on the iPhone - device should attempt to re-register with Microsoft
    Open the iPhone Mail app and look for email with subject: "ACTION REQUIRED TO SYNC EMAIL" (note, this email won't appear in the online version of Outlook, only in the iPhone Mail app)
    Scroll down the message and click on: "Continue using this email app".

Disable Firefox 65+ urlbar/address bar suggestion popups

Leave a reply

According to https://bugzilla.mozilla.org/show_bug.cgi?id=1502392, browser.urlbar.autocomplete.enabled pref is no more used in Firefox 65.
So you can’t set below pref to false to disable the annoying Firefox address bar/url bar popups.

browser.urlbar.autocomplete.enabled
browser.urlbar.suggest.bookmark;false
browser.urlbar.suggest.history;false
browser.urlbar.suggest.searches

The only way to disable the popup is to use userChrome.css to control Firefox User interface.
Add below line to userChrome.css, done.

#PopupAutoCompleteRichResult {
	display: none!important;
}
