GraphQL microservices (GQLMS)

I'm curios of GraphQL !

    - GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015.


It should be solving a problem in querying data !
    -GraphQL lets you ask for what you want in a single query, saving bandwidth and reducing waterfall requests. It also enables clients to request their own unique data specifications.

A case study ?!

So, This is just another database technoloy ?
 - No. GraphQL is often confused with being a database technology. This is a misconception, GraphQL is a query language for APIs - not databases. In that sense it’s database agnostic and can be used with any kind of database or even no database at all.

About Memory: 1. How do I get memory, i.e how are variables declared. Any specific facts and constrains about variables ? If type annotation like var Varb:Float ; is not used then it is mandatory to assign the initial value to the variable. "Var" keyword should get you the required memory. 2. How do we get the entry point for the program execution ? [ Example : main() in the C program ] Script based. There is no particular entry point. 3. How does dynamic memory handled ? Is it supported in first place ? Instances for the classes can be created. Automatic Reference counting mechanism has the strong reference to one of the variable. Till there is strong reference to the variable it'll be there in the memory. Once there is no strong reference it'll be de-initialized. [ Ref : https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/AutomaticReferenceCounting.html ] 4. What are the datatypes which are supported an...

I have went to find the way in which wlan in Kali Linux could be made listed my airmon-ng command. Most of the videos and posts suggested me that it is necessary to have another wi-fi adapter to have connected to wifi network. But this is not necessary. The procedure to do this is as follows: 1. Download this package in Virtual Machine(Kali linux) " http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-06-26-p.tar.bz2" 2.Unzip this package in terminal i.e navigate to place where you have downloaded this file , say desktop then type : cd Desktop for unzip type : tar -jxvf compat-wireless-2010-06-26-p.tar.bz2 3. Navigate into the uncompressed directory and type: i."make unload"  (only words within the quotes are the commands) ii."make load" Done!  now airmon-ng  should have the list of the required devices.
