• Cloud security and privacy

  - by Rakesh K

  Hi, I have a very basic doubt regarding cloud computing that is catching up pretty fast these days. To my understanding, cloud computing is a paradigm in which companies put up their data and applications on somebody else's machines aka 'The Cloud'. I want to know just how secure is it to put up my data on some third party machines, especially if my data contains private details. In particular, how can an enterprise trust the cloud computing service providers in this data privacy aspect? Thanks, rakesh.

• Nice, clean, simple way of getting a dataset from ASP.NET to plain HTML jQuery or JavaScript library

  - by David S

  I know this is a probable open ended question, and I have tried looking around so much over the last year or two... maybe I am looking for a perfect place that doesn't exist! of course it's all about perception no less.. Anyway, just to clarify what I am trying to do and why: I want to be able to use (primarily for the moment) ASP.NET or services thereof to get a dataset - whatever the source data, I can obviously get a dataset of rows/Columns. I want to be able to, as simply as possible, get that data over to the client via xml/json/whatever, to then use in a "variety" of ways. "Variety" of ways meaning I would like to "easily" bind that data to say a grid, or a combo dropdown or just simply render to a textbox - BUT by referencing the dataset as I would say on the serverside. Now I know this all sounds simplistic, and I know there are lots of complications.. so I have tried the following so far over the last year or so: ExtJS - very good, nice solid framework, but just found it a bit too much to use in everyday basic apps - great if I was building a whole application with it Yahoo YUI - not looked recently, but I guess some of the concepts with ExtJS were similar? JQuery - of course to get data etc, it was ok, and I guess there are so many 3rd party plugins, that a mix and match might work? Adobe SPRY - ironically this was as close to getting a dataset style structure to Javascript/client, although it seemed to drop off/go quiet..? I maybe wrong.. I did have a very cursory play with Tibco GI and another one I cannot remember the name of! but again, it felt like it was great to build a whole app perhaps? Anyway, I am very amazed by all of the technologies coming out, and really not biased one way or the other, I really just want a very simple way of getting data from the server, and having a basic/very flexible way of working with that data in the client without using server technologies.. I need to keep the server flexible as I may need to use PHP, or java technologies not just .NET So again, sorry for the rambles, but if anyone out there has had a simple experience, or would like to share some ideas, it would be very welcomed!! David.

• How does assembly language interact with something like the Internet?

  - by Maulrus

  So I was thinking about languages the other day, and it struck me that any program written in a compiled language that interacts with the Internet is then translated into assembly that has to interact with the Internet. I've just begun learning a bit of x86 assembly to help me understand C++ a bit better, and I'm baffled by how something so low-level could do something like access the Internet. I'm sure the full answer to this question is much more than would fit in a SO answer, but could somebody give me maybe a basic summary?

• How does PHP work - literature

  - by Ondrej Slinták

  I'm interested in literature (articles on internet, in magazines, books, podcasts - I don't really mind anything) that describes how PHP works internally, about its gotchas and perhaps some advanced functions. Is there anything like this out there? I tried to search on Google, but majority of articles were about starting with PHP and its basic functions. Any input is really welcome as I'm trying to understand the language internally - I'm tired of my mindless typing of code without understanding its essence.

• Application Buddy Lists and Authentication - How does it all go together

  - by Krevin

  This is a broad but specific question. The idea is that we want to tie in a 'buddy' functionality to a communications app. Very broadly, I believe that the application clients would connect to a central database/auth service which would provide the buddy data and then allow client apps to connect directly to eachother, without passing communications through the server. Specifically, however, what solutions, software, products, servers, technologies, etc would be best to implement to handle such a task? Thanks for reading and responses are much appreciated. //edit: the com app may run on a linux distro, may be web based, or both

• Subclassing NSObject, can it cause problems?

  - by Sheehan Alam

  I have a very basic data class that is subclassed from NSObject. I declare a few strings, make sure they have properties (nonatomic, copy), and synthesize them. The only method I implemented was dealloc() which releases my strings. Can any memory problems arise from just this? Are there any other methods I need to implement?

• Replay attacks for HTTPS requests

  - by MatthewMartin

  Let's say a security tester uses a proxy, say Fiddler, and records an HTTPS request using the administrator's credentials-- on replay of the entire request (including session and auth cookies) the security tester is able to succesfully (re)record transactions. The claim is that this is a sign of a CSRF vulnerability. What would a malicious user have to do to intercept the HTTPS request and replay it? It this a task for script kiddies, well funded military hacking teams or time-traveling-alien technology? Is it really so easy to record the SSL sessions of users and replay them before the tickets expire? No code in the application currently does anything interesting on HTTP GET, so AFAIK, tricking the admin into clicking a link or loading a image with a malicious URL isn't an issue.
