erlang - When should one do Synchronous or Asynchronous sending? -

-

synchronous call : The call that will send an answer is expected.

asynchronous call : calls that will send (block current process)

Although I understand the concept of sync and async , But when it comes to converting these concepts, I usually fail.

Indicates how Deadlock can be avoided to sync calls to send the ADC Call Call with other processes and send data to themselves.

My question: How can one person choose sync or asynchronous calls while creating a real world application in ARLing / OTP.

Rule of my thumb:

  1. -> Use asynchronous message

  7. -> If your process requires a result and can not do it, some synchronous messages (easy to read) can be used. >

    -> If your process requires a result and you should not do anything use synchronous calls in use

मेरे पास एक टेबल है PersonalInfo जैसे कॉलम जैसे आईडी, नाम, पता । मान लें कि मेरा डेटा निम्न है 1 जॉन यूएस 2 मार्क यूके 3 जॉन यूके 4 डेविड यूएस अब जब मैं नया रिकार्ड निम्न सम्मिलित करता हूं 5 जॉन चीन मैं पिछले रिकार्ड को उसी नाम के रूप में अद्यतन करना चाहता हूँ जैसा कि उदाहरण के लिए नया है जैसा कि यहां दिखाया गया है 3 जॉन यूके को 3 जॉन चीन पर अपडेट कर दिया जाएगा। जब मैं 5 वीं रिकॉर्ड को सम्मिलित करता है तो तालिका 1 जॉन यूएस 2 मार्क यूके 3 जॉन चीन 4 डेविड यूएस 5 जॉन चीन मुझे किस SQL ​​क्वेरी का उपयोग करना चाहिए? आईडी मान लेना ऑटो-वर्धित है, यह उस नाम और पता संयोजन के लिए सबसे अधिक मूल्य होगा। सेट पता personalinfo अद्यतन = 'अमेरिका' कहां आईडी = (चयन मैक्स (आईडी) personalinfo से जहां नाम = 'जॉन' और पता = 'ब्रिटेन')

c# - XML serialize base class without knowing derived class -

-
I know that a XmlSerializer throws an exception if the type passed does not match the type Since then the serializer was created My question is: Is it possible to serial the base type without knowing the derivative type? Consider the following scenario: The following classes are in a top-level domain and there is no dependency : Public Class Serializer {Private Static String Serialize (base basedata) {var serializer = New XML serializer (typefile); Var sb = new stringbilder (); (Var author = XmlWriter.Create (sb)) using {serializer.Serialize (author, bassadata); } Return sb.ToString (); } Private static string Deserialize (...) {...}} Public class base {public string name {get; Set; }} The following derivative classes have additional dependencies on things like UI components, structure, etc. (and more on this later): [Export (Typ (IMyComponent)] Public category was created: Base, IMyComponent, INotifyPropertyChanged {public new string name {get {return base.Name; ...

ios - Invalid IPA: missing embedded provisioning profile. Are you sure this is an ad hoc? -

I have searched a lot on the internet but none of the solution works for me. I create an IPA with which it Successfully creates my application and creates an IPA, but when I want to upload it to testflightapp, I get this error: Invalid IPA: missing embedded provisioning profiles Are you sure that this Is an ad hoc? I have added the provisioning profile to create a profile like If I create an IPA manually with Xcode> Product> Archive, then I can successfully upload an IPA to testflightapp. So my guess is that Xcode Maven plugin can not read my provisional profile. I tried to force it by using a private profile in a pom file: Any help would be appreciated. I thought trouble. I was using the wrong IPA file with the Maven goal. I am using IPA from this path: / target / checkout / src / xcode / build / debug-iphonimulator / target / checkout / src / xcode / build / release-iphoneos This was a stupid mistake.
