  • Java Concurrency : Volatile vs final in "cascaded" variables?

    - by Tom
    Hello Experts, is final Map<Integer,Map<String,Integer>> status = new ConcurrentHashMap<Integer, Map<String,Integer>>(); Map<Integer,Map<String,Integer>> statusInner = new ConcurrentHashMap<Integer, Map<String,Integer>>(); status.put(key,statusInner); the same as volatile Map<Integer,Map<String,Integer>> status = new ConcurrentHashMap<Integer, Map<String,Integer>>(); Map<Integer,Map<String,Integer>> statusInner = new ConcurrentHashMap<Integer, Map<String,Integer>>(); status.put(key,statusInner); in case the inner Map is accessed by different Threads? or is even something like this required: volatile Map<Integer,Map<String,Integer>> status = new ConcurrentHashMap<Integer, Map<String,Integer>>(); volatile Map<Integer,Map<String,Integer>> statusInner = new ConcurrentHashMap<Integer, Map<String,Integer>>(); status.put(key,statusInner); In case the it is NOT a "cascaded" map, final and volatile have in the end the same effect of making shure that all threads see always the correct contents of the Map... But what happens if the Map iteself contains a map, as in the example... How do I make shure that the inner Map is correctly "Memory barriered"? Tanks! Tom

  • Contains performs MUCH slower with variable vs constant string MS SQL Server

    - by Greg R
    For some unknown reason I'm running into a problem when passing a variable to a full text search stored procedure performs many times slower than executing the same statement with a constant value. Any idea why and how can that be avoided? This executes very fast: SELECT * FROM table WHERE CONTAINS (comments, '123') This executes very slowly and times out: DECLARE @SearchTerm nvarchar(30) SET @SearchTerm = '123' SET @SearchTerm = '"' + @SearchTerm + '"' SELECT * FROM table WHERE CONTAINS (comments, @SearchTerm) Does this make any sense???

  • array_merge vs array_value for resetting array index

    - by Jamex
    I have 1 array that I want to re-index. I have found that both array_values and array_merge functions can do the job (and I don't need 2 arrays for the array_merge function to work). Which is faster for a very large array? I would benchmark this, but I don't know how and don't have the large array yet. Before re-index: Array ( [0] => AB [4] => EA [6] => FA [9] => DA [10] => AF ) After re-index: Array ( [0] => AB [1] => EA [2] => FA [3] => DA [4] => AF )

  • Asynchronous Delegates Vs Thread/ThreadPool?

    - by claws
    Hello, I need to execute 3 parallel tasks and after completion of each task they should call the same function which prints out the results. I don't understand in .net why we have Asychronous calling (delegate.BeginInvoke() & delegate.EndInvoke()) as well as Thread class? I'm little confused which one to use when? Now in this particular case, what should I use Asychronous calling or Thread class? I'm using C#.

  • Delayed responses for cURL SSL PUTs/POSTs (php) (NSS vs OpenSSL)

    - by Yarin
    I have two Fedora-based apache webservers making the same SSL PUT/POST calls with php/cURL. One works fine, but with the other the call succeeds but takes a VERY long time to return a response (~10 min). (GETs don't seem affected) The working server's cURL uses OpenSSL for SSL, while the non-working version uses a later version of cURL that uses NSS for SSL I know nothing about SSL implementations or their effect on cURL. What would cause such a significant delay in SSL PUT/POST responses? Any suggestions appreciated- Thanks--

  • jquery ajax vs browser url

    - by danwoods
    Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

  • NoSQL vs. MySQL when scalability is irrelevant

    - by Bryan Ward
    Recently I have read a lot about different NoSQL databases and how they are being effectively deployed by some major websites out there. I'm starting a project in which I think the schema-free nature of a database such as MongoDB would be tremendously useful. Everything I have read though seems to indicate that the main advantage of a NoSQL database is scalability. Is choosing a NoSQL database for the schema-free design just as legitimate a design decision as that of scalability?

  • Solr date field tdate vs date?

    - by user550178
    So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)...

  • Speed of NSScanner vs NSXMLParser?

    - by Chris
    I have an iPhone App that reads in an XML file, then pulls out the necessary data by looping through an NSScanner. The XML is not particularly long. I am wondering if it would be worth the work to implement NSXMLParser in place of using NSScanner, if I will see any real improvement in speed?

  • vector's clear vs setsize

    - by SWKK
    I read on the net someplace that in a tight loop if you are clearing your vector repetitively, it might be better to use setsize as it might be faster. I am not sure about this. Anyone's got a definitive answer to this?

  • jQuery Templates vs Partial Views in ASP.NET MVC

    - by Jaco Pretorius
    I'm taking a look at jQuery templates. It looks really interesting - easy syntax, easy to use, very clean. However, I can't really see why it's better to use jQuery templates instead of simply fetching partial views via AJAX. It simply seems like the partial views would be much easier to maintain and helps to avoid duplication of code. I want to use jQuery templates. But when would it be better than partial views?

  • A list vs. tuple situation in Python

    - by Alphonse
    Is there a situation where the use of a list leads to an error, and you must use a tuple instead? I know something about the properties of both tuples and lists, but not enough to find out the answer to this question. If the question would be the other way around, it would be that lists can be adjusted but tuples don't.

  • Folders without Namespaces C#, .Net, VS 2008

    - by Joel
    I'm working on an ASP.NET webapp using the MVP pattern, and as I'm organizing my files I'm wondering - are there conventions on folders within projects and how they relate to namespaces? I have a bunch of controls and a bunch of pages, and I was going to throw them into Controls and Pages folders with subfolders, but I didn't know if it was bad form to do this if I wasn't also going to seperate them out into namespaces. Thanks.

  • PHP Socket Server vs node.js: Web Chat

    - by Eliasdx
    I want to program a HTTP WebChat using long-held HTTP requests (Comet), ajax and websockets (depending on the browser used). Userdatabase is in mysql. Chat is written in PHP except maybe the chat stream itself which could also be written in javascript (node.js): I don't want to start a php process per user as there is no good way to send the chat messages between these php childs. So I thought about writing an own socket server in either PHP or node.js which should be able to handle more then 1000 connections (chat users). As a purely web developer (php) I'm not much familiar with sockets as I usually let web server care about connections. The chat messages won't be saved on disk nor in mysql but in RAM as an array or object for best speed. As far as I know there is no way to handle multiple connections at the same time in a single php process (socket server), however you can accept a great amount of socket connections and process them successive in a loop (read and write; incoming message - write to all socket connections). The problem is that there will most-likely be a lag with ~1000 users and mysql operations could slow the whole thing down which will then affect all users. My question is: Can node.js handle a socket server with better performance? Node.js is event-based but I'm not sure if it can process multiple events at the same time (wouldn't that need multi-threading?) or if there is just an event queue. With an event queue it would be just like php: process user after user. I could also spawn a php process per chat room (much less users) but afaik there are singlethreaded IRC servers which are also capable to handle thousands of users. (written in c++ or whatever) so maybe it's also possible in php. I would prefer PHP over Node.js because then the project would be php-only and not a mixture of programming languages. However if Node can process connections simultaneously I'd probably choose it.

  • vspace vs. vskip

    What is the difference between \vspace{-1em} and \vskip -1em, for example? I guess the first is LaTeX, and the latter is TeX. When is the proper time to use one and not the other, and why?

    Hey guys I created this pacman game in Java. I would like to put in on my website so people can play on there. However I have never done any applets, nor do I know javascript. Is there a way to automatically convert the project into an applet? Or do I have to code it from scratch?
