E-books from M$

along with a very long list of booklets to download… I am grabbing them all, so below is a small download script. By the way, it shows two methods of downloading files:

Start-BitsTransfer -Source "http://www.mssmallbiz.com/ericligman/Key_Shorts/MSFTFreeEbooks.txt" -Destination "filelist.txt" -Priority Low -ProxyUsage SystemDefault -TransferType Download
Get-Content "filelist.txt" | ForEach-Object {Invoke-WebRequest $_ -OutFile $(Split-Path $_ -Leaf)}

Lync and conversation archiving

01/07/2016 Karol

By default, Lync saves conversations in an Outlook folder. This can be changed on the server by running:

Set-CsClientPolicy -Identity global -EnableIMAutoArchiving $false -EnableCallLogAutoArchiving $false

And everything is fine… on the client, the options change from one state to another.

The question is whether this can somehow be done through GPO with filtering. I would like to be able to set it differently per user, so that it is disabled on some workstations and not on others.

The Lync 2010 policies are a bit thin… (Microsoft Lync 2010 Client Group Policy Documentation).

Fortunately, policies from good old Office Communicator still work ;-))) and among 75 other settings there are two that interest us… (Microsoft Office Communications Server 2007 R2 Client Group Policy Documentation).

As a curiosity, this change can also be made through the registry by editing or creating these keys:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Communicator\ImAutoArchivingPolicy (DWORD, 0 - disabled, 1 - enabled)
HKEY_CURRENT_USER\Software\Policies\Microsoft\Communicator\CallLogAutoArchivingPolicy (DWORD, 0 - disabled, 1 - enabled)

Copying the MBR…

14/03/2016 Karol

A small tip. We want to copy the MBR from one disk to another disk with a different partition table.

Copying the MBR directly (only between identical disks!):

#dd if=/dev/sda of=/dev/sdb bs=512 count=1

This copies 512 bytes from disk sda to sdb, but it will work only with identical partition tables.

To copy between different disks:

Copy to a file:

# dd if=/dev/sda of=/tmp/mbrsda.bak bs=512 count=1

Restore to another disk:

# dd if=/tmp/mbrsda.bak of=/dev/sdb bs=446 count=1

This way we preserve the partitioning scheme.
