• Memory allocation in Linux

  - by Goofy

  Hello! I have a multi threaded application where I allocate buffers with data, which then wait in queues to be send via sockets. All buffers are reproducible because I use only buffers of fixed size in whole program (1024, 2048, 2080 and 5248 bytes). I noticed, that my program usually use up to 10 buffers of each length type at the same moment. So far I always manually allocate new buffer and then free it (using malloc() and free ()) where it's not needed any more. I started wondering if Linux is enough smart to cache this memory for me, so next time I allocate new buffer system only quickly receive a buffer I have already used before and not perform heavy operation of allocating new memory block?

• Jquery/CSS help needed to make fallback for IE and older browsers

  - by matt_50

  Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

• style sheet issue

  - by dotnetrocks

  When I add text to my web page using my text editor it display styles correctly inside the text editor which basically is a iframe. After this data is saved it's displayed on another page where the issue occurs. I wanted the description section on my web page to use its own style without getting overwritten by the page styles. Do i need to use a iframe to display this data? Is there a way I can prevent a block from using the page style. Please advise. Appreciate all your help.

• Remove Attributes onmouseover and onmouseout

  - by Abs

  Hello all, I am trying to make use of JQuery's remove attribute like this: $('#rom-img_1').removeAttr('mouseover'); $('#rom-img_2').removeAttr('mouseout'); However, it does not remove the effects of the events as the events are still triggered on mouseover and on mouseout. I have tried adding "on" before the events names too but JQuery doesn't use it like that. Why isn't this working and how can I remove those attributes. This is a bit of the HTML: <div onmouseout="$('#heart_401').css({'display':'none'});" onmouseover="$('#heart_401').css({'display':'block'});" id="row-img_11"></div> Thanks all for any help

• Escaping if/else in Jade template

  - by Collin Estes

  So I have a simply block of html in my jade template with a loop: each dude, i in dudes div(class='someClass') div.otherStuff span.someContent #{name} I want to apply a data attribute to my top most div when a certain looping condition is met, in this case the first dude, I set it up like this each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') else div(class='someClass') div.otherstuff span.someContent Setup like this it causes the div.otherStuff div and the span.someContent to only display on the else condition. I've moved the tab spaces around on those items but I can't get it escape that else and give the div.otherStuff and span.someContent to both the first dude and the subsequent dudes after that. I've also tried setting that data attr to a variable and trying to apply it that way but without any success. What I end up doing to get around it is this: each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') div.otherstuff span.someContent else div(class='someClass') div.otherstuff span.someContent How do I escape that if/else so I dont have to duplicate the div.otherStuff and span.someContent?

• RadGrid Ajax PopAlert

  - by user272671

  I have a situation where I need to, based on user selection and some server-side processing, display a message to allow user to choose to continue processing or cancel. I have a RadGrid populated with data from the database. When User adds a new item to the grid,I want to do some processing in the back end and then inform the user of what could result and give him/her the choice to continue and believe that a message box or modal popup/radalert is the best way to do it, but how do I create the message in the back end and then using a popup, display the message and block until user responds. How do I do it please?

• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

• Is it possible to start an activity from a regular java class?

  - by Yotam

  In my ActionBarSherlock I have the same menu items for all activities, so it seems unwise to define onClick handlers in each activity - they all do the same. Instead I created a class called MyClickListener that implements com.actionbarsherlock.view.MenuItem.OnMenuItemClickListener, and in there I have a simple switch block that starts the appropriate activity. Problem is that Intent constructor's first argument is of type Context, and even when I pass this to MyClickListener's constructor, I can't start any activity. The same goes for every method that has a Context object as a parameter. Is there a way to work around it? What is a context object? Thanks

• Can a function defined in a bookmarklet be called from a page-level script?

  - by Soviut

  I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

• How-to handle errors in Vim Script ?

  - by ereOn

  In my .vimrc file, I have the following function, which folds the licensing information on the top of some .hpp and .cpp files: " Skip license function! FoldLicense() if !exists("b:foldedLicense") let b:foldedLicense = 1 1;/\*\//fold endif endfunction au BufRead *.hpp call FoldLicense() au BufRead *.cpp call FoldLicense() This works well, but if I open a .cpp file which doesn't have any licensing information block, Vim complains that the pattern is not found. Fair enough, but is there a way so that he stops complaining and just does nothing if the pattern is not found ? Thanks !

• PL/SQL embedded insert into table that may not exist

  - by Richard

  Hi, I much prefer using this 'embedded' style inserts in a pl/sql block (opposed to the execute immediate style dynamic sql - where you have to delimit quotes etc). -- a contrived example PROCEDURE CreateReport( customer IN VARCHAR2, reportdate IN DATE ) BEGIN -- drop table, create table with explicit column list CreateReportTableForCustomer; INSERT INTO TEMP_TABLE VALUES ( customer, reportdate ); END; / The problem here is that oracle checks if 'temp_table' exists and that it has the correct number of colunms and throws a compile error if it doesn't exist. So I was wondering if theres any way round that?! Essentially I want to use a placeholder for the table name to trick oracle into not checking if the table exists.

• reStructuredText for SQL?

  - by Chris

  I am trying to use DocUtils and reStructuredText to comment SQL code. I can get this to work when I include the markup inside multi-line comments. I then use --Some text:: to introduce each block of code. I cannot get internal hyperlinks to work. I would like to write -- .. Step1_: but the parser ignores this because of the leading comment. Using a multi-line style also fails. Is there a way to get this to work? Here's an example: /* ========== this query ========== :Author: Me Outline ========== - Create table 1 - Create table 2 - Output the result */ -- _Step1: build the table:: create table table1 -- _Step2: use Step1_ to build table 2:: create table table2

• Help with running crontab from root

  - by user242065

  Im using OSX and having trouble getting a cron job to run. I type the following: $ sudo -i $ crontab -e I then enter: * * * * * root ifconfig en0 down > /dev/null 0 19 * * * root ifconfig en0 down > /dev/null 0 7 * * * root ifconfig en0 up > /dev/null and no success, the first line is for testing.

• How to allow certain HTML tags in a form field in Symfony 1.2

  - by camomileCase

  I'm playing around with Symfony and have encountered a road block. I created a model "CmsPage" which has a field called "content" which is stored as a clob (this is specific to doctrine I believe). When I created the app I set "--escaping-strategy=on" so if I enter any html when editing a CmsPage that gets encoded with html entities or something along those lines. I would like to allow html in this field and a quick googling hasn't helped much. Maybe I'm searching for the wrong terms. Anywho I would like to disable character escaping for this field and possibly only allow a small selection of html tags. What is the correct way to do this in Symfony?

• Advanced text search in actionscript-return ALL nouns,adjectives and verbs..

  - by eco_bach

  Hi I know that as3 has some powerful new text search capabilities, especially when combined with regex. I don't even know if this is possible, but I would like to somehow, search any block of text, and return all nouns, adjectives and verbs. What would be the best(most efficent) way to do this? Is regex an option? or would I have to load in some sort of open sourced dictionary 9as used in spellcheckers) to compare with or?? After, I've pulled all the nouns, adjectives and verbs, I need to count and prioritize by their frequency. Any suggestions welcome...

• What is the best way to declare a property?

  - by Simon

  Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name // LINE 3 @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

• How do i hide html until its processed with javascript?

  - by acidzombie24

  I am using some JS code to transform my menu into a drilldown menu. The problem is before it runs the JS you see a BIG UGLY mess of links. On their site its solved by putting the js at the top. Using recommendations by yahoo/YSlow i am keeping the JS files at the bottom. I tried hiding the menu with display:none then using jquery to .show(), .css('display', ''), .css('display', 'block') and they all lead up to a messsed up looking menu (i get the title but not the title background color or any links of the menu) How do i properly hide a div/menu and show it after being rendered?

• Anonymous iterator blocks in Clojure?

  - by Checkers

  I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of anonymous iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

• UIView animations on a path not linear

  - by chis54

  I have an iOS application that I want to animate a falling leaf (or several). I have my leaf image in an ImageView and I've figured out a simple animation from the documentation: [UIView animateWithDuration:4.0f delay:0 options:UIViewAnimationTransitionFlipFromLeft animations:^(void) { leaf1ImageView.frame = CGRectMake(320, 480, leaf1ImageView.frame.size.width,leaf1ImageView.frame.size.height); } completion:NULL]; This will make the leaf go from its starting position to the bottom right corner in a straight line. How would I animate this to follow a path or curve like a parabola or sinusoid and maybe even rotate the image or view? Would this be done in the animations block? Thanks in advance!

• Avoiding try/catch hell in my web pages

  - by Shaun_web

  I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

• Which method of adding items to the ASP.NET Dictionary class is more efficient?

  - by ahmd0

  I'm converting a comma separated list of strings into a dictionary using C# in ASP.NET (by omitting any duplicates): string str = "1,2, 4, 2, 4, item 3,item2, item 3"; //Just a random string for the sake of this example and I was wondering which method is more efficient? 1 - Using try/catch block: Dictionary<string, string> dic = new Dictionary<string, string>(); string[] strs = str.Split(','); foreach (string s in strs) { if (!string.IsNullOrWhiteSpace(s)) { try { string s2 = s.Trim(); dic.Add(s2, s2); } catch { } } } 2 - Or using ContainsKey() method: string[] strs = str.Split(','); foreach (string s in strs) { if (!string.IsNullOrWhiteSpace(s)) { string s2 = s.Trim(); if (!dic.ContainsKey(s2)) dic.Add(s2, s2); } }

• Saving core data in a thread, how to ensure its done writing before quitting?

  - by Shizam

  So I'm saving small images to core data which take a really short amount of time to save, like .2 seconds but I'm doing it while the user is flipping through a scroll view so in order to improve responsiveness I'm moving the saving to a thread. This works great, everything gets saved and the app is responsive. However, there is one thing in the core-data + multithreading doco that worries me: "In Cocoa, only the main thread is not-detached. If you need to save on other threads, you must write additional code such that the main thread prevents the application from quitting until all the save operation is complete." Ok, how do you do that? It only needs to last ~ .2 seconds and its rarely going to happen since the chance of the app quitting as something is saving is very low. How do I run something on the main thread that'll prevent the app from quitting AND not block the gui? Thanks

• prevent linux thread from being interrupted by scheduler

  - by johnnycrash

  How do you tell the thread scheduler in linux to not interrupt your thread for any reason? I am programming in user mode. Does simply locking a mutex acomplish this? I want to prevent other threads in my process from being scheduled when a certain function is executing. They would block and I would be wasting cpu cycles with context switches. I want any thread executing the function to be able to finish executing without interruption even if the threads' timeslice is exceeded.
