    What are the differences between RPC and RMI?

    Posted: 25 Feb 2020 03:55 PM PST

    I am reading about RPC and RMI in Coulouris' Distribute Systems book, and am wondering what are the differences between RPC and RMI? (Although RMI seems unpopular nowadays, I don't know whether a RPC service written in an OO language is a RPC service or a RMI service, see my question in part 4.)

    1. I heard that a RPC service and its clients can be written in different languages. Must a RMI service and its clients be written in the same language?

    2. Is it correct that a RPC service is stateless, while a RMI service is stateful? (I got that impression that in RMI, a remote object can store state, according to https://old.reddit.com/r/compsci/comments/f8q047/is_rmi_still_popular/fio7byg/ )

    3. When using RMI, must the methods that are invoked remotely be instance methods of a class, because RMI is stateful?

      When RPC (e.g. gRPC) is used in OO languages, are service procedures defined as methods of a class? Should the methods be static/class methods of the class, or instance methods of the class? I guess static/class methods, because RPC is stateful. But when using gRPC with C#, service procedures are not declared as static methods in its class, for example, SayHello() is a service procedure created from a .proto file, and is SayHello() an instance method of class GreeterBase?

      [grpc::BindServiceMethod(typeof(Greeter), "BindService")] public abstract partial class GreeterBase { public virtual global::System.Threading.Tasks.Task<global::GrpcGreeter.HelloReply> SayHello(global::GrpcGreeter.HelloRequest request, grpc::ServerCallContext context) { throw new grpc::RpcException(new grpc::Status(grpc::StatusCode.Unimplemented, "")); } }

    4. Given the previous question, how do you distinguish whether a service written in an OO language is a RMI service or a RPC service?

    Thanks.

    Computer Science vs Applied Computing

    Posted: 25 Feb 2020 05:38 PM PST

    Heyo! First off, I want to apologize if this is the type of question seen often and that it likely gets repetitive. I'd just like to get more information from people here who are around the field as I'm currently hoping to snatch a Cybersecurity/Tech job in the future! I'm currently a Comp Sci major with a concentration in Cybersecurity (little odd as another college had a class purely called CyberSec. but I ended up going elsewhere). I haven't really been sure what degree will likely do me more justice in the future as they also have an Applied Computing degree with a concentration in Cybersecurity. Not to mention that the courses seem easier in that major. What type of degree do you guys think will be more beneficial? I'm aware that Computer Science seems like its a bit of a broad major as it can branch out into multiple field such as software engineering. However, I feel like AC can branch out in its own sense. Thanks for your time!

    How do I prepare for masters?

    Posted: 25 Feb 2020 11:12 AM PST

    I really want to study Computer science after undergrad. I'm not sure what field I want to focus on. One of the main advice I got from surfing the web was doing my own research. Now how does one do their own research? Like how do I choose the topic and if we have one, how do I know if it hasn't been done before by other people? And most importantly how does one start doing the research? Thank you!

    Can a RPC service and a RPC client written in different languages work together?

    Posted: 25 Feb 2020 02:37 PM PST

    • Can a RPC service and a RPC client written in different languages work together? (For comparison, a REST service and its clients can be written in different languages. A RMI service and its clients seem to me must be written in the same OO language.) For example, gRPC can be used in many languages. For a gRPC service written in C#, can I write a gRPC client in Python to communicate with it? Vice versa. Similarly between Java and Python, between Java and C#.

    • Must the service and client be written in terms of the same technology, not different ones? For example, gRPC service and Sun RPC clients can't work together?

    • Must the input and output parameters be serialized and deserialized in a language-agnostic format?

    • Must the service interface be defined in a language independent of the languages for writing the service and client? (That is true for gRPC)

    Any more reasons or conditions/requirements?

    Thanks.

    [R] MonoLayout | Bird’s-Eye Layout Estimation from A Single Image

    Posted: 25 Feb 2020 02:04 PM PST

    Recently, researchers from Robotics Research Center at IIIT Hyderabad, IIT Kharagpur, Mila, and Université de Montréal addressed the challenge with MonoLayout, a practical deep neural architecture that takes just a single image of a road scene as input and outputs an amodal scene layout (which can show all regions even if some regions are being occluded by other objects) in bird's-eye view.

    Resources for practicing recursion in Python

    Posted: 25 Feb 2020 10:13 AM PST

    I have a Python exam next week that includes recursion. Would anyone be able to recommend any online resources that have a bunch of "practice" problems/solutions? I find just doing a whole bunch of problems is the best way for me to learn via pattern recognition. Thanks for any recommendations

    Resources to learn automatas

    Posted: 25 Feb 2020 05:55 AM PST

    Hey, I'm starting a course in automatas next semester, and I wanted to know what are some great resources to learn automatas? The course covers finite automatas, regular languages and grammars. I've heard of Sipser, is that any good? Appreciate any resources
