  Financial Apps feel the need for speed – this can come via parallelization, and via infrastructure - fast messaging and non-blocking distributed memory management. This blogpost gives an overview + examples of various technologies that can squeeze performance out of your trading apps and clock cycles out of your modeling apps. Low Latency via Infrastructure ZeroMQ · ZeroMQ is a messaging library - ‘messaging middleware’ , ‘TCP on steroids’ , ‘new layer on the networking stack’. not a complete messaging system , but is a simple messaging library to be used programmatically. Gives the
flexibility and performance of low level socket interface plus ease of implementation of high level. It is designed for simplicity. · Performance - ZeroMQ is orders of magnitude faster than most AMQP messaging systems as it doesn’t have the overhead. It leverages efficient transports such as reliable Multicast and makes use of intelligent message batching, minimizing not only protocol overhead but also system calls. You can choose the message encoding format such as BSON or ProtoBuff. o ZeroMQ sockets can connect to multiple end points and automatically load balance messages over them. It is brokerless and thus has...(Read whole news on source site)

by Senthil Kumar When submitting one of my Apps (Number Converter for Windows Phone) to the Windows Phone Marketplace, I got this error when uploading my .XAP file The [NeutralResourceLanguage] attribute is missing on the entry assembly.

NeutralResourceLanguage to English. ...(Read whole news on source site)

null is not false

AddThis Social Bookmark Button
The way you typically represent a "missing" or "invalid" value in C# is to use the "null" value of the type. Every reference type has a "null" value; that is, the reference that does not actually refer to anything. And every "normal" value type has a corresponding "nullable" value type which has a null value. The way these concepts are implemented is completely different. A reference is typically implemented behind the scenes as a 32 or 64 bit number. As we've discussed previously in this space, that number should logically be treated as an "opaque" handle that
only the garbage collector knows about, but in practice that number is the offset into the virtual memory space of the process that the referred-to object lives at, inside the managed heap. The number zero is reserved as the representation of null because the operating system reserves the first few pages of virtual memory as invalid, always. There is no chance that by some accident, the zero address is going to be a valid address in the heap. By contrast, a nullable value type is simply an instance of the value type plus a Boolean that indicates whether the value...(Read whole news on source site)

Windows 8 Developer Event in New York City on April 19, 2012

AddThis Social Bookmark Button
Back on March 13th, I announced a series of Windows 8 Developer Camps coming to cities up and down the US east coast starting this week and running through April & May 2012.  There was one location that eerily seemed to be missing from the list of tour dates:  New York City! (or as my teammate Rachel Appel likes to say, “The Capital of the World!”) So what gives?! New York City is a special place… being the capital of the world and all.  Microsoft wanted to be able to do something special there for the
first big Windows 8 Developer event there. As such, the details were not all in place when I announced the Windows 8 Developer Camps earlier this month.  Now they are, and I’m happy to announce that April 19, 2012 will be the Windows 8 Developer Event in New York City!!!  The event will be at Center 548 on the West Side near Chelsea Piers.  Read on for registration & details… Windows Reimagined Learn everything you need to start building Metro-style apps for Windows today at our free, full-day Windows Developer Event.
