By default, when the Private computer checkbox is visible, it is checked by default, meaning that OWA will store some things in your browser by default. Sometimes, this may not be desirable, and you may prefer the checkbox is unchecked by default so as to prevent this. There is no setting to change this default, but there's a workaround, allowing you to obtain the same result. The only downside of this workaround is that it needs to be done anew after each update of Exchange.

To show the Private Computer checkbox in the first place, read this article about enabling the option.

To apply the workaround, you need to manually edit the logon.aspx page so it does not check the checkbox by defaul  ...

Exchange OWA stores data offline in your browser for a better user experience and performance. In older releases of Exchange, this behaviour could be turned off at the logon page by unchecking a checkbox, but since Exchange 2013, this checkbox is no longer visible on the logon page. But, this option can be turned on again by changing a configuration option of OWA in Exchange.



The option can be enabled through EMS on the CAS server. If you have more than one CAS server, this needs to be done on all of them.

Get-OwaVirtualDirectory | Set-OwaVirtualDirectory -LogonPagePublicPrivateSelectionEnabled $true

After the change, don't forget to reload IIS:

iisreset /noforce

Optionally, you can a  ...

In VMWare Workstation and vSphere ESX, it is possible to set disks to be independent so they are not linked to snapshots. Independent disks can then be set to be Persistent (changes are written immediately and permanently to disk) or Non-persistent (changes are lost when the VM powers down). In VMWare Fusion, although this option does not seem to be present, it is still available, and can be configured by manually changing the parameters in the VM configuration file (.vmx).

A VM configuration file is a text-based file containing all the parameters and properties for a VM. This file can include options that are not present in the Fusion UI. By adding parameters manually, you can enable featu  ...

nginx provides packages for Debian in their own repository, allowing you to install the most recent version rather than the older versions provided through the main repositories.

Add these lines to /etc/apt/sources.list:

deb http://nginx.org/packages/mainline/debian/ jessie nginxdeb-src http://nginx.org/packages/mainline/debian/ jessie nginx

Change jessie to wheezy if you are still on Debian 7 "Wheezy".

Download and add nginx's public key:

wget http://nginx.org/packages/keys/nginx_signing.key && cat nginx_signing.key | apt-key add -

Update the package list and then install nginx:

apt-get updateapt-get install nginx

I had an issue with an app being stuck in Paused mode in Launchpad, and was unable to cancel/resume the update from the App Store because it wasn't listed in the updates list.

The solution, as stated here, was to open Launchpad, hold down the mouse on the app until it started jiggling, then clicking the delete button (x). The app reappeared normally and was even updated correctly.

The reason was probably the app got updated along with a system update, and Launchpad was unaware the update was completed.
