Random outpourings of a software developer
There are a couple of useful powershell command-line tools that are of use:
This is useful to query tasks and work items
tfpt query “ProjectPath to query”
From a mapped folder allows the running of existing tfs work item queries from the command-line
It uses the current folders mapping to identify the project.
This is useful for quering checkins:
Run from the VS2012 command prompt:
tf history x:path_to_project /recursive /noprompt /user:”My User Name”

In order to improve performance on Azure table operations it is advised to batch them.
However the documentation does not clearly state that the batch must all have the same PartionKey and may only contain 100 items.
Here is a the project.
Here is a great intro to github for you and your cat.
These are some useful links on javascript frameworks.
jQuery is currently the best of breed for what it does.
Here is how to generically query Azure Table Storage without having to define the entity that is in the table (which you may not know and can vary).
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(diagnostics);
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable cloudTable = tableClient.GetTableReference(“WADLogsTable”);
TableQuery query = new TableQuery();
query.FilterString = filter;
var items = cloudTable.ExecuteQuery(query).ToList();
See my previous post for how to set the filters.

String PartitionKey eq ‘myPK’
DateTime Timestamp eq datetime’2010-08-13T10:32:38.
Here is a great article on Azure Table Storage performance.
Short version always access via the Partition Key unless you want a table scan.
You can however search over a range of Partion Keys.
The most efficient version is Partition Key + Row Key
The financial system is currently using the Value at Risk model.
One of the fundamental assumptions of it is that the trades used are normally distributed. The benefit of assuming normal distribution is that it is well known and easy to calculate. You can’t assume normal distribution. Is the height of a large enough population normally distributed? If you believe so where are the 6m tall humans or those less than 0m tall? These are reasonably expected to exist in a large enough normally distributed population.
