sowmyawrites .... » TechExperiences: Neuro Science lessons for the day : Hysteria
I was reading one of V.S.Ramachandran’s 2003 Reith lectures, titled – ‘Neuro Science – The new philosophy’, in which he introduces a new approach to neuro science – called ‘Evolutionary neuro-psychiatry’. Well, despite all my ignorance to brain and its science, I find it an irresistable temptation to read about them. Despite all those intimidating names like – amygdala, hippocampus, fusiform gyrus, penfield homunculus – (whatever… there are 100s of such names..in these 5 lectures itself), I can’t resist reading these things.
Oh, I usually dont remember a single scientific name among these after completing the essay. What I take with me are only the answers to some questions. Its like -
“Why does synesthesia occur?”
“Because of a cross connection between the color and number areas” is a decent enough explanation for me. I can go beyond that a bit and explain- without going to the extent of a scientist. As a commoner, thats more than enough for my appetite.
Ok, coming to why I began writing this – its because of “Hysteria“. The word hysteria conjures up an image of a angry female shouting madly as if she lost her wits (somehow, its always a female). So, when I came across that word in VSR’s essay, and his actual ‘medical’ definition for that, I was shocked. Here it goes:
“In the strictly medical sense, the word means that here is a patient who suddenly develops a paralysis of an arm or a leg, but if you examine this patient neurologically there are no deficits, brain MR scan reveals that the brain is apparently completely normal, there are no identifiable lesions, there’s no damage. So the symptoms are dismissed as being purely psychological in origin.”
Wow! Is there any slightest relation to its popular usage? 
If you want to stop here and go read that article, go here. I was surprised at this ‘hysterically’ different meaning of the word in medical and non-medical diction, and thought of exploring the web a bit.
A look at the wikipedia page – gave me an impression that its a woman thing. (Just as I see a woman’s image all the time). But, Ramachandran’s definition does not mention anything of that sort.
A look at the medical dictionary online (here) gave me two distinct names, finally:
Hysterical disorder is the the one VSR explained.
Histrionic disorder – is hysteria in the mango people lingo.
The same have also been referred to as ’somatization disorder’ and ‘conversion/dissociative disorder’ respectively, says another dictionary.
What baffles me again, is the origin of the word.
“Until the seventeenth century, hysteria was regarded as of uterine origin (from the Greek “hustera” = uterus) in the Western world. “
(More on this in the Wiki page)
-Where did its journey began? Where is it now?
Well, more than the evolution of language, evolution of word meanings is interesting me now

sowmyawrites .... » TechExperiences: On Synesthesia and Vilayanur Ramachandran
I was reading one of the BBC Reith Lectures of 2003 by V.S.Ramachandran, the famous neurologist. I would rather prefer to call him a ‘psycho physicist’ if there is a word like that. This lecture was on ‘synesthesia‘ and its implications as well as applications in the real world. It was a joy reading this essay. Its not just about knowing what synesthesia is. A wikipedia page will do to get a definition. It was the explanation, interpretation and getting it till – “evolution of language” – all done in a simple and easy to understand manner – that is making me write this post.
Okay, let me brief on what ‘Synesthesia’ is. ‘Synesthesia’ can be understood as a cross-relation between different senses. The typical example : mapping numbers to colors. (See this figure). In this figure, if you view the left hand side as the right hand side – it means that you are a synesthete . Well, I didn’t. I did not see the triangle pattern of 2s when I saw the figure, because, I saw 5 as 5 and not “green” – thats exactly what synesthetes do.
And my doubts on the causes- The article mentioned four common explanations that were proposed for this issue:
1. These people are just crazy
2. They may be under the influence of drugs
3. They are just recalling some childhood memories
4. This might indicate how metaphors work
-For point 3, VSR mentioned a logic saying – But sinesthesia is hereditary. How can people have same childhood memories over generations? I wonder – doesn’t that logic apply for 2 and to some extent – 1? I mean – may be “craziness” is hereditary in some cases. But, sometimes it may not be right ? (Iam not a doc I am just guessing that it need not be hereditary always). So, VSR’s logic should hold true for points 1 and 2 too – is my understanding.
The best part of this reading experience is that : if you are a neuro science person, you can enjoy this as a good technical read. If you are a lay-person like me – you can still enjoy reading this.
It was a joy reading this book – so far…
A text version is available on the BBC site here.
(I read it in the book – a collection of these lectures titled : “The Emerging Mind”)

Bharath Radhekrishna: Interview Questions on WCF – Part 1
Every service must have Address that defines where the service resides, Contract that defines what the service does and a Binding that defines how to communicate with the service. In WCF the relationship between Address, Contract and Binding is called Endpoint.
The Endpoint is the fusion of Address, Contract and Binding.
What is binding and how many types of bindings are there in WCF?
A binding defines how an endpoint communicates to the world. A binding defines the transport (such as HTTP or TCP) and the encoding being used (such as text or binary). A binding can contain binding elements that specify details like the security mechanisms used to secure messages, or the message pattern used by an endpoint.
WCF supports nine types of bindings.
Basic binding
Offered by the BasicHttpBinding class, this is designed to expose a WCF service as a legacy ASMX web service, so that old clients can work with new services. When used by the client, this binding enables new WCF clients to work with old ASMX services.
TCP binding
Offered by the NetTcpBinding class, this uses TCP for cross-machine communication on the intranet. It supports a variety of features, including reliability, transactions, and security, and is optimized for WCF-to-WCF communication. As a result, it requires both the client and the service to use WCF.
Peer network binding
Offered by the NetPeerTcpBinding class, this uses peer networking as a transport. The peer network-enabled client and services all subscribe to the same grid and broadcast messages to it.
IPC binding
Offered by the NetNamedPipeBinding class, this uses named pipes as a transport for same-machine communication. It is the most secure binding since it cannot accept calls from outside the machine and it supports a variety of features similar to the TCP binding.
Web Service (WS) binding
Offered by the WSHttpBinding class, this uses HTTP or HTTPS for transport, and is designed to offer a variety of features such as reliability, transactions, and security over the Internet.
Federated WS binding
Offered by the WSFederationHttpBinding class, this is a specialization of the WS binding, offering support for federated security.
Duplex WS binding
Offered by the WSDualHttpBinding class, this is similar to the WS binding except it also supports bidirectional communication from the service to the client.
MSMQ binding
Offered by the NetMsmqBinding class, this uses MSMQ for transport and is designed to offer support for disconnected queued calls.
MSMQ integration binding
Offered by the MsmqIntegrationBinding class, this converts WCF messages to and from MSMQ messages, and is designed to interoperate with legacy MSMQ clients.
For WCF binding comparison, see http://www.pluralsight.com/community/blogs/aaron/archive/2007/03/22/46560.aspx
Where we can host WCF services?
Every WCF services must be hosted somewhere. There are three ways of hosting WCF services.
They are
1. IIS
2. Self Hosting
3. WAS (Windows Activation Service)
For more details see http://msdn.microsoft.com/en-us/library/bb332338.aspx
In WCF, all services expose contracts. The contract is a platform-neutral and standard way of describing what the service does.
WCF defines four types of contracts.
Service contracts
Describe which operations the client can perform on the service.
There are two types of Service Contracts.
ServiceContract – This attribute is used to define the Interface.
OperationContract – This attribute is used to define the method inside Interface.
[ServiceContract]
interface IMyContract
{
[OperationContract]
string MyMethod( );
}
class MyService : IMyContract
{
public string MyMethod( )
{
return “Hello World”;
}
}
Data contracts
Define which data types are passed to and from the service. WCF defines implicit contracts for built-in types such as int and string, but we can easily define explicit opt-in data contracts for custom types.
There are two types of Data Contracts.
DataContract – attribute used to define the class
DataMember – attribute used to define the properties.
[DataContract]
class Contact
{
[DataMember]
public string FirstName;
[DataMember]
public string LastName;
}
If DataMember attributes are not specified for a properties in the class, that property can’t be passed to-from web service.
Fault contracts
Define which errors are raised by the service, and how the service handles and propagates errors to its clients.
Message contracts
Allow the service to interact directly with messages. Message contracts can be typed or untyped, and are useful in interoperability cases and when there is an existing message format we have to comply with.
What is address in WCF and how many types of transport schemas are there in WCF?
Address is a way of letting client know that where a service is located. In WCF, every service is associated with a unique address. This contains the location of the service and transport schemas.
WCF supports following transport schemas
HTTP
TCP
Peer network
IPC (Inter-Process Communication over named pipes)
MSMQ
The sample address for above transport schema may look like
http://localhost:81
http://localhost:81/MyService
net.tcp://localhost:82/MyService
net.pipe://localhost/MyPipeService
net.msmq://localhost/private/MyMsMqService
net.msmq://localhost/MyMsMqService
What is service and client in perspective of data communication?
A service is a unit of functionality exposed to the world.
The client of a service is merely the party consuming the service.
Windows Communication Foundation (WCF) is an SDK for developing and deploying services on Windows. WCF provides a runtime environment for services, enabling you to expose CLR types as services, and to consume other services as CLR types.
WCF is part of .NET 3.0 and requires .NET 2.0, so it can only run on systems that support it.
What is the difference WCF and Web services?
Posted by: Raja | Show/Hide Answer
Web services can only be invoked by HTTP (traditional webservice with .asmx). While WCF Service or a WCF component can be invoked by any protocol (like http, tcp etc.) and any transport type.
Second web services are not flexible. However, WCF Services are flexible. If you make a new version of the service then you need to just expose a new end. Therefore, services are agile and which is a very practical approach looking at the current business trends.
We develop WCF as contracts, interface, operations, and data contracts. As the developer we are more focused on the business logic services and need not worry about channel stack. WCF is a unified programming API for any kind of services so we create the service and use configuration information to set up the communication mechanism like HTTP/TCP/MSMQ etc
For more details, read http://msdn.microsoft.com/en-us/library/aa738737.aspx
What are various ways of hosting WCF Services?
Posted by: Raja | Show/Hide Answer
There are three major ways of hosting a WCF services
• Self-hosting the service in his own application domain. This we have already covered in the first section. The service comes in to existence when you create the object of Service Host class and the service closes when you call the Close of the Service Host class.
• Host in application domain or process provided by IIS Server.
• Host in Application domain and process provided by WAS (Windows Activation Service) Server.
More details http://www.dotnetfunda.com/articles/article221.aspx#whatarethevariouswaysofhostingaWCFservice
What are the main components of WCF?
Posted by: Raja | Show/Hide Answer
The main components of WCF are
1. Service class
2. Hosting environment
3. End point
For more details read http://www.dotnetfunda.com/articles/article221.aspx#WhatarethemaincomponentsofWCF
What was the code name for WCF?
Posted by: Raja | Show/Hide Answer
The code name of WCF was Indigo .
WCF is a unification of .NET framework communication technologies which unites the following technologies:-
NET remoting
MSMQ
Web services
COM+
How to deal with operation overloading while exposing the WCF services?
By default overload operations (methods) are not supported in WSDL based operation. However by using Name property of OperationContract attribute, we can deal with operation overloading scenario.
[ServiceContract]
interface ICalculator
{
[OperationContract(Name = "AddInt")]
int Add(int arg1,int arg2);
[OperationContract(Name = "AddDouble")]
double Add(double arg1,double arg2);
}
Notice that both method name in the above interface is same (Add), however the Name property of the OperationContract is different. In this case client proxy will have two methods with different name AddInt and AddDouble.
How to set the timeout property for the WCF Service client call?
The timeout property can be set for the WCF Service client call using binding tag.
<client>
<endpoint
…
binding = “wsHttpBinding”
bindingConfiguration = “LongTimeout”
…
/>
</client>
<bindings>
<wsHttpBinding>
<binding name = “LongTimeout” sendTimeout = “00:04:00″/>
</wsHttpBinding>
</bindings>
If no timeout has been specified, the default is considered as 1 minute.
How to configure Reliability while communicating with WCF Services?
Reliability can be configured in the client config file by adding reliableSession under binding tag.
<system.serviceModel>
<services>
<service name = “MyService”>
<endpoint
address = “net.tcp://localhost:8888/MyService”
binding = “netTcpBinding”
bindingConfiguration = “ReliableCommunication”
contract = “IMyContract”
/>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name = “ReliableCommunication”>
<reliableSession enabled = “true”/>
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
Reliability is supported by following bindings only
NetTcpBinding
WSHttpBinding
WSFederationHttpBinding
WSDualHttpBinding
What is Transport and Message Reliability?
Transport reliability (such as the one offered by TCP) offers point-to-point guaranteed delivery at the network packet level, as well as guarantees the order of the packets. Transport reliability is not resilient to dropping network connections and a variety of other communication problems.
Message reliability deals with reliability at the message level independent of how many packets are required to deliver the message. Message reliability provides for end-to-end guaranteed delivery and order of messages, regardless of how many intermediaries are involved, and how many network hops are required to deliver the message from the client to the service.
What are different elements of WCF Srevices Client configuration file?
WCF Services client configuration file contains endpoint, address, binding and contract. A sample client config file looks like
<system.serviceModel>
<client>
<endpoint name = “MyEndpoint”
address = “http://localhost:8000/MyService/”
binding = “wsHttpBinding”
contract = “IMyContract”
/>
</client>
</system.serviceModel>
What is Proxy and how to generate proxy for WCF Services?
The proxy is a CLR class that exposes a single CLR interface representing the service contract. The proxy provides the same operations as service’s contract, but also has additional methods for managing the proxy life cycle and the connection to the service. The proxy completely encapsulates every aspect of the service: its location, its implementation technology and runtime platform, and the communication transport.
The proxy can be generated using Visual Studio by right clicking Reference and clicking on Add Service Reference. This brings up the Add Service Reference dialog box, where you need to supply the base address of the service (or a base address and a MEX URI) and the namespace to contain the proxy.
Proxy can also be generated by using SvcUtil.exe command-line utility. We need to provide SvcUtil with the HTTP-GET address or the metadata exchange endpoint address and, optionally, with a proxy filename. The default proxy filename is output.cs but you can also use the /out switch to indicate a different name.
SvcUtil http://localhost/MyService/MyService.svc /out:Proxy.cs
When we are hosting in IIS and selecting a port other than port 80 (such as port 88), we must provide that port number as part of the base address:
SvcUtil http://localhost:88/MyService/MyService.svc /out:Proxy.cs
What is the address formats of the WCF transport schemas?
Address format of WCF transport schema always follow
[transport]://[machine or domain][:optional port] format.
for example:
HTTP Address Format
http://localhost:8888
the way to read the above url is
“Using HTTP, go to the machine called localhost, where on port 8888 someone is waiting”
When the port number is not specified, the default port is 80.
TCP Address Format
net.tcp://localhost:8888/MyService
When a port number is not specified, the default port is 808:
net.tcp://localhost/MyService
NOTE: Two HTTP and TCP addresses from the same host can share a port, even on the same machine.
IPC Address Format
net.pipe://localhost/MyPipe
We can only open a named pipe once per machine, and therefore it is not possible for two named pipe addresses to share a pipe name on the same machine.
MSMQ Address Format
net.msmq://localhost/private/MyService
net.msmq://localhost/MyService
How to define a service as REST based service in WCF?
WCF 3.5 provides explicit support for RESTful communication using a new binding named WebHttpBinding.
The below code shows how to expose a RESTful service
[ServiceContract]
interface IStock
{
[OperationContract]
[WebGet]
int GetStock(string StockId);
}
By adding the WebGetAttribute, we can define a service as REST based service that can be accessible using HTTP GET operation.

MataManthi » టెక్నాలజీ: పెద్ద ఫైల్స్ ని పంపాలనుకుంటున్నారా: ఎలాగో చూడండి
ఎప్పుడైనా మీ మిత్రులతో సన్నిహితులతో మీవద్ద ఉన్న సమాచారాన్ని, లేదా వేరే ఎవన్నా ఫైల్స్ ని పంచుకోవాల్సిన అవసరం వస్తుంది. అటువంటి అప్పుడు పెద్ద పెద్ద ఫైల్స్ ని వారికి ఇంటర్నెట్ ద్వారా ఎలా పంపగలమో చూద్దాం.
ఈమెయిలు ని ఉపయోగించండి: గూగుల్, యాహూ వంటి ఈమెయిలు సర్వీసుల ద్వారా 25 ఎమ్ బి వరకు డేటా పంపవచ్చు. కాని 25 ఎమ్ బి ని మించి సమాచారాన్ని పంపటం వీటి ద్వారా సాధ్యం కాదు. అంతకన్నా ఎక్కువ దాతా ను పంపాలి అని అనుకుంటే లైకొస్ మెయిల్ (lycos mail ) ని ఉపయోగించవచ్చు. దీనికి అనుసంధానించే (attach ) చేసే సమాచారం పై కాని ఫైల్ సైజు పై కాని ఎటు వంటి నియంత్రణ లేదు. కాని ఆ సమాచారాన్ని పంపే వారు, అందుకునే వారు ఇరువురు లైకొస్ మెయిల్ ను మాత్రమే ఉపయోగించాలి.
