Entity Framework 4 and “New transaction is not allowed because there are other threads running in the session” Exception

At Jim Jackson's Blog, solution was simple, get you query and copy to list.

".ToList()" than work on your items.

C# Cast Array N To T ?

Easy way to cast for example Type1[] to Type2[]

Primative types in c# has mostly convertors already like ; 

Just one line of code...

 var STRARRAY = new string[] { "10", "11", "12" };

Array.ConvertAll<string, uint>(STRARRAY.Split(','), Convert.ToUInt32) ;

You might code your own as well.

public static TOutput[] ConvertAll<TInput, TOutput>( TInput[] array, Converter<TInput, TOutput> converter )

Do you think you are fast?

OCZ's Virtualized Controller Architecture™ (VCA) 2.0 provides the utmost in performance, flexibility, durability and enhanced reliability, allowing data centers to rely on a PCIe-based SSD as their primary tier one storage solution for the first time.

You will get `The associated private key is marked as not exportable` unless `Mark the private key as exportable` checked ... and it is too late already.

HyperDex: A Searchable Distributed Key-Value Store

HyperDex

HyperDex is a distributed, searchable key-value store. HyperDex provides a unique search primitive which enables searches over stored values. By design, HyperDex retains the performance of traditional key-value stores while enabling support for the search operation.

The key features of HyperDex are:

Fast HyperDex has lower latency and higher throughput than most other key-value stores.

Searchable HyperDex enables lookups of non-primary data attributes. Such searches are implemented efficiently and contact a small number of servers.

Scalable HyperDex scales as more machines are added to the system.

Fault tolerant HyperDex handles failures. Data is automatically replicated on multiple machines so that failures do not cause data loss.

More $s with PHP

You might wanna make things easier with more $ signs with PHP 

How it works : 

$a='b';

$b='a';

// take value of $a and use it as variable name so '$b'

echo $$a 

output : a

Just works ;

<?

$a='b';$b='a';

echo $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$a;

?>

^Z

output: b

As this ; 

<?

$a='b';$b='a';

echo $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$a;

?>

^Z

output: a
