Feed Reader: Should It Always Be Client Side?

Should a browser based Feed Reader always use something on the client side, like Javascript? UPDATE: I mean, specifically, for the Parsing of RSS. If you can offload it to the browser, it seems almost irresponsible to make your server do the work. Still, there are plenty of advantages in my particular situation to doing it server side....

Is a client-server setup a good way to move data between machines?

I need to move some data from one machine to another. Is it a good idea to write a client server app using sockets in Perl to do the transfer? Will I have problems if one side is written in Java? I mean, should I be aware of any issues I might face when I try to attempt the above? ...

How do I prevent non-legit client apps from using my server?

I’m currently writing a pair of client/server applications. I was recently posed with the question of “how do I prevent someone from writing their own client application and using our server?” I really didn’t have an answer to that question because all of the secure communication stuff I have done to date is to ensure the communication...

I'm working on a basic 2D flash MMO. The first alpha will contain the basics: players can move around. This is, I think, also the most important part to be highly optimized.

Here is where I am at presently. I am designing a card game with the aim of utilizing major components for future work. The part that is hanging me up is creating a layer of abstraction between the server and the client(s). A server is started, and then one or more clients can connect (locally or remotely). I am designing a thick client ...

Multiple replies from server for one client request

This may be a dumb question - and the title may need to be improved... I think my requirement is pretty simple: I want to send a request for data from a client to a server program, and the server (not the client) should respond with something like "Received your request - working on it". The client then does other work. Then when the...

SQLite for client-server

Hi, I've seen a couple of SQLite performance questions here on Stackoverflow, but the focus was on websites, and I'm considering using this DB in a client-server scenario: I expect 1-10 clients for one server for now, could go up to 50 or more in the future. slightly more reads than writes the DB would sit behind a server process (i.e...

In a multitier application should a client be allowed to send its own linq expressions to the server?

The rationale: HQL and NH criteria are NHibernate specific constructs and as such they are server side DAL implementation details. I do not want them to "leak" to the client side. So, our client side provides LINQ expressions for the server to process. Seems legitimate to me, some, however, think otherwise and so I would like to know ...

Hi, I'm interested in creating a sort of hand-off authentication method, where there's a client and two servers (let's call them Alice, Bob and Carmen Sandiego, respectively).

I am trying to rearchitecture a program which runs on Win CE 5.0 devices, using Compact Framework. Right now the application communicates directly with the database, pulling down data, making changes, and sending those back to the database. Each client is responsible for retrieving updates via polling the database. I want to develop som...

What is the recommended method of testing a JSON client-server api?

Edit #2: Does anyone have a good method of testing the "middle" of a client-server application where we can intercept requests and responses, fake the client or server as needed, and which provides self-documentation of the api? Cucumber might be a good solution in many cases, but it's not quite what I'm looking for. And this middle la...

Hi, I'm building a client-server application and I am looking at adding failover to the client so that when a server is down it will try to connect to another available server. Are there any standards or specifications covering server failover? I'd rather adopt an existing standard than implement my own mechanism. ...
