Using GIT from a network share

Running git on a remote network share, even when you have a good connectivity, is painful and slow.

It turns out someone clever has a better approach to using git in this use case.

Useful Docker and LXD info

Documentation

Developer documentation of using docker inside LXD
There are problems using docker inside LXD, many applications cannot run inside a LXD, this can in part be mitigated by applying the docker profile provided by LXD but this does not work for many applications.

Use OLE DB (Excel Spreadsheet) in SSRS

I have been learning a lot of SSRS and SQL server recently and have wondered how to apply the awesome toolset of SSRS to some other problems I have found.

From most of the resources I have found it is usually quoted that the only way to use excel as a datasource for SSRS is by adding the excel document as a ODBC, however in lots of environments that will not be possible due to security settings. 

In the back of my mind I was sure that I had seen excel used with OLE DB data source before. 

Finally I found an example of it working here;

https://social.msdn.microsoft.com/Forums/sqlserver/en-US/1b52b758-1787-4aa2-a760-f98090667788/excel-data-source-for-report-without-using-odbc?forum=sqlreportingservices

Essentially you use the following connection string

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";

and all works as hoped 

Success!

The only other point to make is that you need to reference the sheet name with a $ suffix,

SELECT
F1 AS rowNum
,F2 AS theValue
FROM
[Data3$]

I wish I found these earlier!

Checksums in Windows

For a while I have been meaning to find a good checksum tool that I can use within windows but have gotten around to doing it properly.

SuperUser to the rescue:
http://superuser.com/questions/166233/is-there-a-built-in-method-for-computing-an-sha-1-or-md5-hash-in-windows-7
http://superuser.com/questions/245775/is-there-a-built-in-checksum-utility-on-windows-7

These led me to this:
http://code.kliu.org/hashcheck/

There is another alternative named HashTab but after reading this and looking at each of the options I ended preferring the look of Hashcheck.
