• How can i allow people in my local network to access the web service in my machine?

  - by user1451704

  I have coded a web service using the Axis 2 framework and I can successfully invoke it using a test client (SoapUI) on the local machine after publishing the application in JBoss 5. I can post to the WS endpoint from the local machine and get the expected response. Now i want to allow other machines to access the web service. i changed the "localhost" to "my own fixed IP" adress at the end point location, and turned firewall off, but impossible to access the WS. Note : windows Xp SP3. Any idea ? Thanks in advance !!

• getting the value of a filter at an arbitrary time

  - by Andiih

  Context: I'm trying to improve the values returned by the iPhone CLLocationManager, although this is a more generally applicable problem. The key is that CLLocationManger returns data on current velocity as and when it feels like it, rather than at a fixed sample rate. I'd like to use a feedback equation to improve accuracy v=(k*v)+(1-k)*currentVelocity where currentVelocity is the speed returned by didUpdateToLocation:fromLocation: and v is the output velocity (and also used for the feedback element). Because of the "as and when" nature of didUpdateToLocation:fromLocation: I could calculate the time interval since it was last called, and do something like for (i=0;i<timeintervalsincelastcalled;i++) v=(k*v)+(1-k)*currentVelocity which would work, but is wasteful of cycles. Especially as I probably want timeintervalsincelastcalled to be measured as 10ths of a second. Is there a way to solve this without the loop ? i.e. rework (integrate?) the formula so I put an interval into the equation and get the same answer as I would have by iteration ?

• How bad is for SEO to "redirect" an user depending on his browser locale ?

  - by bgy

  For a personnal page I use the MultiViews options in Apache to determine which page he should see depending on his locale. Here is what I do. Options MultiViews AddLanguage fr .fr AddLanguage en .en <IfModule mod_negotiation.c> LanguagePriority fr en </IfModule> I am wondering if it is bad for SEO to do this since Googlebot will probably fall on 'fr' or 'en' but not both. Would it be fixed if I add a link inside my page to the different language page.

• jQuery: how to find first visible input/select/textarea excluding buttons?

  - by Artem

  I tried $(":input:not(input[type=button],input[type=submit],button):visible:first") but it doesn't find anything. What is my mistake? UPD: I execute this on $(document).load() <script type="text/javascript"> $(window).load(function () { var aspForm = $("form#aspnetForm"); var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm); firstInput.focus(); }); </script> and in the debug I can see that firstInput is empty. UPD2: I'm in ASP.NET page running under Sharepoint. I've found so far that for some elements it does find them (for fixed ones) and for some don't. :(

• jquery background image fade

  - by Nick

  I am using jQuery to load ina background image that fills the page width / height. I have the following in the Head: $(document).ready(function() { $('body').css({ 'background-image' : 'url({HTML_BASE}images/backgrounds/randoms/{BACK_IMG})', 'background-repeat' : 'no-repeat', 'background-position' : 'center top', 'background-attachment': 'fixed', 'background-size': '100% 100%', }); $('#home-promo').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: 'auto' }); $('.model-search').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: '393' }); }); This works fine and can be seen at http://projects.snowshtechnologies.com/golden_dragon/home/ I want the BG image to fade in from the black background colour. I have looked at a few other threads on Stack that suggest its not possible as a body element defined in css, but in this scenario the BG image is being loaded in by jQuery. How would I go about adding a fade in to this code to bring the image in with a nice fadein?

• 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?

• how to make the footer div start after all other divs have finished

  - by amit

  i am having a slight problem with the alignment of the footer div. i have a header at the top. div = maincontent { two divs for content, side by side. another 2 divs side by side below the content div. } //just to represent. i know this is not html ;) now i want the footer div to start after the maincontent div finishes. i can do that if i specify a fixed height for the maincontent div. but i dont want to specify a height for it. if i dont specify the height, the footer div starts at the middle of the page. what am i doing wrong?

• small string optimization for vector?

  - by BuschnicK

  I know several (all?) STL implementations implement a "small string" optimization where instead of storing the usual 3 pointers for begin, end and capacity a string will store the actual character data in the memory used for the pointers if sizeof(characters) <= sizeof(pointers). I am in a situation where I have lots of small vectors with an element size <= sizeof(pointer). I cannot use fixed size arrays, since the vectors need to be able to resize dynamically and may potentially grow quite large. However, the median (not mean) size of the vectors will only be 4-12 bytes. So a "small string" optimization adapted to vectors would be quite useful to me. Does such a thing exist? I'm thinking about rolling my own by simply brute force converting a vector to a string, i.e. providing a vector interface to a string. Good idea?

• Virtual String Tree - Display subnode when parent node is hidden

  - by daemon_x

  Is there a way to show subnode if the parent node is hidden in the Virtual String Tree ? I have some tasks in the tree structure and I wish to display only tasks which belongs to the current user as the list, but from all levels. What I've done is the function to display a list, which hides tree buttons, tree lines, sets the fixed indent and enable toShowHiddenNodes option. Then in this function I iterate through the whole tree (all levels) and hide nodes which doesn't belong to the current user IsVisible[Node] := False and show those which belongs him IsVisible[Node] := True, but the subnodes which should be displayed are invisible when their parent is hidden. VT.TreeOptions.PaintOptions - toShowButtons - toShowTreeLines + toFixedIndent + toShowHiddenNodes

• PHP array of object(stdClass) fusion/intersect?

  - by Gremo

  $arr1 is an associative array of anonymus objects: array 15898 => object(stdClass)[8] public 'date' => int $arr2 is another associative array with two (or more, it's not fixed) properties: array 15898 => object(stdClass)[10] public 'fruits' public 'drinks' I can't find any function for intersect and content fusion when dealing with objects. Basically i'd like to obtain: array 15898 => object(stdClass)[8] public 'date' => int public 'fruits' public 'drinks' Question is: is this even possible?

  class Product(models.Model): ... image = models.ImageField(upload_to = generate_filename, blank = True) When I use ImageField (blank=True) and do not select image into admin form, exception occures. In django code you can see this: class FieldFile(File): .... def _require_file(self): if not self: raise ValueError("The '%s' attribute has no file associated with it." % self.field.name) def _get_file(self): self._require_file() ... Django trac has ticket #13327 about this problem, but seems it can't be fixed soon. How to make these field optional?

• Regex for xml parsing

  - by ogmios

  What is your opinon about following regexes - is it correct? To find element with spcific and required attribute "<(" + elem_name + ")(\s+(?:[^<]?\s+)" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3[^<])(.*?)" To find element with spcific but optional attribute "<(" + elem_name + ")(\s*|\s+(?:[^<]?\s+)(?:" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3)?[^<])(.*?)" Pleas not another answer "use existing xml parser". Question is - are the regexes proper or not? This is specific situation - C language in embedded system and xml is not well-formed (cannot be fixed - does not depend on me). Xml have specified schema and no problem with namespaces etc. exists.

• Beginner questions regarding Python classes.

  - by Andy

  Hi. I am new to Python so please don't flame me if I ask something too noobish :) 1. Consider I have a class: class Test: def __init__(self, x, y): self.x = x self.y = y def wow(): print 5 * 5 Now I try to create an object of the class: x = Test(3, 4) This works as expected. However, when I try to call the method wow(), it returns an error, which is fixed by changing wow() to: def wow(self) Why do I need to include self and if I don't, what does the method mean?2. In the definition of __init__: def __init__(self, x, y): self.x = x self.y = y Why do I need to declare x and y, when I can do this: def __init__(self): self.x = x self.y = y I hope I am being clear... Thanks for your time.

• Setting precision on std::cout in entire file scope - C++ iomanip

  - by Ivan

  Hi all, I'm doing some calculations, and the results are being save in a file. I have to output very precise results, near the precision of the double variable, and I'm using the iomanip setprecision(int) for that. The problem is that I have to put the setprecision everywhere in the output, like that: func1() { cout<<setprecision(12)<<value; cout<<setprecision(10)<<value2; } func2() { cout<<setprecision(17)<<value4; cout<<setprecision(3)<<value42; } And that is very cumbersome. Is there a way to set more generally the cout fixed modifier? Thanks

• .net exception pool

  - by javier

  I want to create a mecanism in a large .net application to handle all the exceptions in the application, and to save the error messages (in db or log file) so these errors can be fixed, and so we are aware of the problems in the application. Does anyone know a good way of creating a library to handle and process all the exceptions?. Are there any tools around that can simplify my task. What aproach would you suggest me to take.... If you previously implemented something similar to what I want to do, I do want to heard from you Thanks all

• Don't panic - there is time!

  - by ripper234

  If you're thinking of moving to Shapado right this instance, take a breath. Yes, I think it's the right move in the long run (be it three months or a year). However, take into consideration that the platform is still not ready. It has bugs and feature-requests that should be fixed. Until they are, you are better off staying with Stack Exchange as long as you can. Of course, it is in your best interest to participate heavily in the 'meta discussion' that takes place at Shapado.com and vote on the features and bug fixes that you want.

• Auto height and the float issue.

  - by William Hand

  I have had this issue before and can't remember if and how I fixed it. I have to create a scenario where I have 2 DIV's floated left and right inside a parent DIV. The 2 floating DIV's have height:auto, but the parent ignores them (perfectly logical) and the background of the parent DIV can't be seen. I know what the issue is, but are there any suggestions of how to solve it? Or any alternatives, I am willing to try a new approach. Thanks in advance for any help.

• Connection: Keep-Alive and PHP sessions not working

  - by user366667

  We have a VB application that needs to run an specific flow on a PHP page. This application was correctly catching the PHPSESSID cookie and using it for all subsequent requests. However, PHP wasn't able to restore any changes made on $_SESSION variable. The variable was changed, saved, and on the next request it was restored as an empty array. We found out that changing the Connection header from "Keep-Alive" to "Close" fixed the issue. I couldn't find anything on the web saying that PHP sessions shouldn't be restored under Keep-Alive connections. Does anyone know why this was happening? PS: We didn't find anything weird or different on Apache, ModSecurity or PHP configuration settings.

• What happens when I release a upgrade with higher targeted sdk as previous version?

  - by Peterdk

  SoundPool has a serious bug in it in Android 1.5. I fixed it with a workaround, but since it really limits my app, I want to target 1.6+ for the next version of it. I am wondering: What happens when I release a upgrade that has a higher target SDK version then the previous version of my app? Will only 1.6+ users be able to upgrade their app? Or will also the 1.5 users be able to upgrade since they have the program already installed? Anybody experience with this?

• ASP.NET Server.Execute

  - by justin

  I'm having some problems with Server.Execute that I can't seem to find any details on. Page page = new WidgetProcessor(Widget); Server.Execute(page, htmlTextWriter, true); The Widget in the above code is a simple object that knows how to instantiate a usercontrol. The WidgetProcessor takes a Widget and adds the widgets control to the page. This works fine on the initial load, it doesn't seem to handle postbacks however; it never actually fires the user controls events, it just consistently returns the original page as if you had never posted back. I've found this article from 2003: http://support.microsoft.com/kb/817036, though I would think they would have fixed this by now. Any help would be appreciated.

• Using adaptive step sizes with scipy.integrate.ode

  - by Mike

  The (brief) documentation for scipy.integrate.ode says that two methods (dopri5 and dop853) have stepsize control and dense output. Looking at the examples and the code itself, I can only see a very simple way to get output from an integrator. Namely, it looks like you just step the integrator forward by some fixed dt, get the function value(s) at that time, and repeat. My problem has pretty variable timescales, so I'd like to just get the values at whatever time steps it needs to evaluate to achieve the required tolerances. That is, early on, things are changing slowly, so the output time steps can be big. But as things get interesting, the output time steps have to be smaller. I don't actually want dense output at equal intervals, I just want the time steps the adaptive function uses.
