• jquery carousel

  - by Adam Wright

  Hi, I'm looking for a jquery carousel to contain image with the following requirements: must run on auto must not pause must be able to pause on image hover must have external controls that once clicked change the direction of the carousel. must be able to fadeout buttons when the carousel is moving in that direction. I've looked at jcaursel and jcaousellite but both have a pause of in auto mode or you have to specify how many items to slide. I just want it to move continously like a news ticker. Any suggestions on how to achieve this or how to customise jcaurousel or jcarouselite?

• Profiling help required

  - by Mick

  I have a profiling issue - imagine I have the following code... void main() { well_written_function(); badly_written_function(); } void well_written_function() { for (a small number) { highly_optimised_subroutine(); } } void badly_written_function() { for (a wastefully and unnecessarily large number) { highly_optimised_subroutine(); } } void highly_optimised_subroutine() { // lots of code } If I run this under vtune (or other profilers) it is very hard to spot that anything is wrong. All the hotspots will appear in the section marked "// lots of code" which is already optimised. The badly_written_function() will not be highlighted in any way even though it is the cause of all the trouble. Is there some feature of vtune that will help me find the problem? Is there some sort of mode whereby I can find the time taken by badly_written_function() and all of its sub-functions?

• pthreads recursively calling system command and segfault appears

  - by jess

  I have a code base where i am creating 8 threads and each thread just calls system command to display date in a continuous cycle, as shown below: void * system_thread(void *arg) { int cpu = (int)arg; printf("thread : start %d\n", cpu); for (;;) { // date ã³ãã³ãã®å®è¡ if (mode == 0) { system("date"); } else { f_hfp_nlc_Fsystem("date"); } } sleep(timerval); return NULL; } This application segfaults after running for 2-3 seconds, due to following 2 reasons: 1. read access, where the address is out of VM area 2. write acces, where it does not of write permission and its trying to modify some structure.

• Data 'logger' turning off when phone goes to standbymode

  - by Marko Järvenpää

  I'm creating a datalogger which logs the gps data and the sensor data of the phone. I've just a strange problem. If the phone is not touched for few minutes it goes into standby mode (screen goes black), and that causes the logger to stop working. Actually the firewriting in the logger stops working. The GPS resumes fine after coming out of blackscreen, but when I check the log I created it only shows saved points for few minutes. Does anyone have idea what is causing this?

• Why is hierarchyviewer not working for Samsung Galaxy TAB 7.0?

  - by FireAndIce

  I've used hierarachyviewer earlier, but on android emulator. It works absolutely fine when I use it on the emulator. However it does not work with Samsung Galaxy TAB 7.0, with Android 2.3.4. This is the log, that I get 11:04:22 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:04:22 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:04:24 E/hierarchyviewer: Unable to debug device 30359964881B00EC 11:05:05 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:05:05 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:05:07 E/hierarchyviewer: Unable to debug device 30359964881B00EC 11:09:38 E/hierarchyviewer: Unable to get view server version from device 303599 64881B00EC 11:09:38 E/hierarchyviewer: Unable to get view server protocol version from devi ce 30359964881B00EC 11:09:40 E/hierarchyviewer: Unable to debug device 30359964881B00EC I'm also not using hierarchyviewer in the debug mode, just running the application.

• How do I create an empty file in emacs?

  - by Singletoned

  How can I create an empty file from emacs, ideally from within a dired buffer? For example, I've just opened a Python module in dired mode, created a new directory, opened that in dired, and now need to add an empty __init__.py file in the directory. If I use C-x C-f __init__.py RET C-x C-s then emacs doesn't create the file because no changes have been made to it. I would have to type in the file, save it, delete my typing and then save it again for that to work. Thanks

• Trying to use the "Use Specific Printer" option in Access 2007

  - by garynei

  I am trying to set a report to use a specific printer. I go into design mode, click on the page setup ribbon, click the page setup bottun, go into the page tabt, click the option to choose a specific printer, and then click the printer button to choose the printer I want to use. I save the steps and exit out of the report, but it still goes back and prints from the default printer. Why? I had no problems with this feature in 2003, why am I having problems in 2007. Any suggestions on how to fix this problem would be greatly appreciated, thanks.

• How do game trainers change a address in memory thats dynamic?

  - by GameTrainersWTF

  Lets assume i am a game and i have a global int* that contains my health. A game trainers job is to modify this value to whatever in order to achieve god mode. I've looked up tutorials on game trainers to understand how they work, and the general idea is to use a memory scanner to try and find the address of a certain value. Then modify this address by injecting a dll or whatever. But i made a simple program with a global int* and its address changes every time i run the app, so i don't get how game trainers can hard code these addresses? Or is my example wrong? What am i missing?

• why does the gingerbread emulator orientation gets stuck in apps?

  - by tabjsina

  At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

• Hard drive randomly sppeeding up

  - by Glenn Taylor

  Having a weird issue with my hard drive. Running Windows 7 with an I5 processor. At random times the hard drive will start running at top speed and gradually return to normal over the next two minutes or so. Going to Resource Monitor it shows a variety of things with high read or write numbers. Log files NTFS volume log, Windows prefetch, System/user/appdata, and Program data Norton are the usual top ones listed. This just started about three months ago although the computer is about 3 years old. Have run in safe mode with internet over the weekend going to all of my usual sites with no such speed up. Question 1 - what can be causing this? Question 2 - how can I find out where data is being sent(especially if over the net)? Thank you.

• Vim: How to handle newlines when storing multiple commands in registers?

  - by UncleZeiv

  I have a file where I store snippets of vim commands. When I need a snippet, I yank it and then execute it with @". The snippets are stored as a script, one line per command, like this: :s/foo/bar/g :echo "hello" :s/1/2/g Edit: I removed normal mode commands from the example, as they were not part of the problem. Now this procedure doesn't work anymore: when executing the snippet, it just stops at the first line as if waiting for a newline. Is there an option somewhere affecting how @ is executed? I'm pretty sure it was working some time ago... Substituting the newline with a ^M character works but makes the file more difficult to handle. Additional information: Here's another symptom: when I yank a snippet, if I execute it with @" it stops at the first line as I just explained. But if I execute it with :@ it works. But the help file doesn't seem to imply any difference in how the two commands treat the register's content...

• Runtime Error in asp.net?(online )

  - by Surya sasidhar

  hi, I develop a web application it is working fine in local. When i upload the site in online through CuteFTP it is showing the error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. please help me i place the but even though it is not working it is giving same error. Thank you

• Perl: Why does "use strict" not let me pass a parameter hash?

  - by Thariama

  I hava a perl subroutine where i would like to pass parameters as a hash (the aim is to include a css depending on the parameter 'iconsize'). I am using the call: get_function_bar_begin('iconsize' => '32'); for the subroutine get_function_bar_begin: use strict; ... sub get_function_bar_begin { my $self = shift; my %template_params = %{ shift || {} }; return $self->render_template('global/bars /tmpl_incl_function_bar_begin.html',%template_params); } Why does this yield the error message: Error executing run mode 'start': undef error - Can't use string ("iconsize") as a HASH ref while "strict refs" in use at CheckBar.pm at line 334 Am i doing something wrong here? Is there an other way to submit my data ('iconsize') as a hash?

• How to temporarily change all default user settings without destroying the original?

  - by mystify

  My app is based strongly on a lot of NSUserDefault keys and values. I want to implement a temporary defaults profile which the user can activate to get a special task done easily. For this, some of the user defaults must be changed temporarily so the app adjusts it's interface appropriately. I started to just manually change those NSUserDefaults settings, but this also destroys the user's original settings. Is it possible to keep a backup of the user's NSUserDefault settings and restore them after the user quits the temporary mode or the app? Like I see it, NSUserDefaults actually is just an NSMutableDictionary which is generated out of a plist file. So I would just make a deep copy of that and later assign that copy somehow back to NSUserDefaults?

• Write set of integers to std::ofstream and be able to read them back

  - by bndu

  Hello, I need to write a bunch of unsigned integers to std::ofstream in binary mode: std::ofstream f; f.open("some path", std::ios::out | std::ios::binary); // some loop { unsigned int k = get_k(); // may product numbers from 0 to 65535 f << k; } f.close(); They are written to the output file "as is" w/o any delimiter. So when I'm trying to read them back (expecting to get what I wrote) using std::ifstream I get very strange values. What I'm doing wrong? Or I should to put ' ' (space) to the stream after any added number to separate them? Thanks.

• How do I tell Entity Framework that a column in a view is nullable?

  - by Ryan ONeill

  I have a view which has an Int column which is nullable (let's call it StackOverflowCount). When generating an EF model from the database, the EF designer does not recognise it as nullable and creates the column as an Int. The issue I have is that on the EF designer I have set the column to Nullable and the following error then kills the compilation; Error 3031: Problem in mapping fragments starting at line 2327: Non-nullable column MyView.StackOverflowCount in table MyView is mapped to a nullable entity property. I can get round this by opening the .edmx file in XML mode and manually editing the SQL column definition, but there is no way to do this using the designer and it gets overwritten the next time I refresh from the model from the DB. Is this 'by design' or an example of something that slipped through into EF 4.0? I'm using .Net 4.0 with EF 4.0 under VS 2010.

• SQL Express 2008 R2 on Amazon EC2 instance: tons of free memory, poor performance

  - by gravyface

  The old SQL Express 2005 was running on a low-end single Xeon CPU Dell server, RAID 5 7200 disks, 2 GB RAM (SBS 2003). I have not done any baseline measurements on the old physical server, but the Web app is used by half a dozen people (maybe 2 concurrently), so I figured "how bad can an Amazon EC2 instance be?". It's pretty horrible: a difference of 8 seconds of load time on one screen. First of all, I'm not a SQL guru, but here's what I've tried: Had a Small Instance, now running a c1.medium (High Cpu Medium) Windows 2008 32-bit R2 EBS-backed instance running IIS 7.5 and SQL Express 2008 R2. No noticeable improvement. Changed Page File from fixed 256 to Automatic. Setup a Striped Mirror from within Disk Management with two attached 1 GB EBS volumes. Moved database and transaction log, left everything else on the boot EBS volume. No noticeable change. Looked at memory, ~1000 MB of physical memory free (1.7 GB total). Changed SQL instance to use a minimum of 1024 RAM; restarted server, no change in memory usage. SQL still only using ~28MB of RAM(!). So I'm thinking: this database is tiny (28MB), why isn't the whole thing cached in RAM? Surely that would speed up performance. The transaction log is 241 MB. Seems kind of large in comparison -- has this not been committed? Is it a cause of performance degradation? I recall something about Recovery Models and log sizes somewhere in my travels, but not positive. Another thing: the old server was running SQL Express 2005. Not sure if that has any impact, but I tried changing the compatibility level from SQL 2000 to 2008, but that had no effect. Anyways, what else can I try here? Seems ridiculous to throw more virtual hardware at this thing. I know I/O is going to be rough on EBS volumes, but surely others are successfully running small .NET/SQL apps on reasonably priced instances?

• How do I get MSBuild Task to generate XML Documents when building a solution?

  - by toba303

  I have a solution with lots of projects. Each project is configured to generate the XML documentation file when building in Debug-Mode (which is default). That works when I build in Visual Studio 2008. In my build script on my integration server I advise MSBuild to build the whole solution, but it won't generate the documentation files. What can I do? I already tried to explicitly give the Debug-Condition to the build process, but it makes no difference. <Target Name="BuilSolution"> <MSBuild Projects="C:\Path\To\MySolution.sln" targets="Build" Properties="SolutionConfigurationPlatforms='Debug|Any CPU'"/> </Target> There seem to be some ideas to solve this problem when building single projects, but I can't afford to do this, so I need a hint for doing it this way. Thanks in advance!

• Show a SplashScreenScene before to GameScene?

  - by lisovaccaro

  I want to add a splash screen to my game. I created a SplashScene.sks and a SplashScene.swift file. I'm trying to load my SplashScene before GameScene but I cannot manage to do it. How should I do this? This is what I'm trying now: class GameViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let skView = self.view as SKView skView.ignoresSiblingOrder = true /* Set the scale mode to scale to fit the window */ var scene = SplashScreenScene() // Present SplashScreenScene first scene.scaleMode = .AspectFill skView.presentScene(scene) } Then on my SplashScreenScene: class SplashScreenScene: SKScene { override func didMoveToView(view: SKView) { self.size = view.bounds.size self.anchorPoint = CGPointMake(0.5, 0.5) var background = SKSpriteNode(imageNamed:"LaunchImage") self.addChild(background) // Start timer to load next scene NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("changeScene"), userInfo: nil, repeats: false) } func changeScene() { let scene = GameScene() view.presentScene(scene) } } This is very close to the solution, however for some reason when I do this my game becomes laggy (if I present GameScene directly the game runs fine).
