• How to keep windows 2003 Daylight Saving values updated

  - by SirMoreno

  My web app runs on windows 2003 .Net 3.5 I have users from Israel (GMT +2), and Israel switched to Daylight saving time on 26/3/10 so now it's (GMT +3). I use TimeZoneInfo.ConvertTime that doesn’t know the Daylight saving time switch is on 26/3/10 so it still converts to GMT +2. I asked on StackOverflow: http://stackoverflow.com/questions/2530834/problem-with-timezoneinfo-converttime-missed-the-daylight-saving-switch/2532104#2532104 And I was told that I need to update: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Israel Standard Time\Dynamic DST I found this update: http://support.microsoft.com/kb/976098 That supposes to fix the Dynamic DST for 2010, Is this the update I need? Where can I find an update that handles 2011 2012… ? Will I need to update my windows every year to get the DST right? Thanks.

• jQuery Autocomplete Json Ajax cross browser issue with Google Search Appliance

  - by skyfoot

  I am implementing a jquery autocomplete on a search form and am getting the suggestions from the Google Search Appliance Autocomple suggestions service which returns a result set in json. What I am trying to do is go off to the GSA to get suggestions when the user types something in the search box. The url to get the json suggestions is as follows: http://gsaurl/suggest?q=<query>&max=10&site=default_site&client=default_frontend&access=p&format=rich The json which is returned is as follows: { "query":"re", "results": [ {"name":"red", "type":"suggest"}, {"name":"read", "type":"suggest"}] } The jQuery autocomplete code is as follows: $(#q).autocomplete(searchUrl, { width: 320, dataType: 'json', highlight: false, scroll: true, scrollHeight: 300, parse: function(data) { var array = new Array(); for(var i=0;i<data.results.length;i++) { array[i] = { data: data.results[i], value: data.results[i].name, result: data.results[i].name }; } return array; }, formatItem: function(row) { return row.name; } }); This works in IE but fails in firefox as the data returned in the parse function is null. Any ideas why this would be the case? Workaround I created an aspx page to call the GSA suggest service and to return the json from the suggest service. Using this page as a proxy and setting it as the url in the jQuery autocomplete worked in both IE and FireFox.

• Zend: How to populate data to checkboxes?

  - by NAVEED

  I am working on zend. I have a form with some checkboxes. I want to get data from database and populate this data to this form. If '1' is stored in table field then tick the check box otherwise leave it alone. In textboxes and dropdowns, data is easily populated but how to check a checkbox in action. I am creating checkboxes and textboxes elements like this in form.php: // Person name $person = $this->CreateElement('text', 'name'); $person->setLabel('Name'); $elements[] = $person; // Organization name $person = $this->CreateElement('text', 'organization'); $person->setLabel('Organization'); $elements[] = $person; // isAdmin Checkbox $isAdmin = $this->CreateElement('checkbox', 'isAdmin'); $isAdmin->setLabel('Admin'); $elements[] = $isAdmin; $this->addElements($elements); $this->setElementDecorators(array('ViewHelper')); // set form decorator (what script will render the form) $this->setDecorators(array(array('ViewScript' , array('viewScript' => 'organization/accessroles-form.phtml')))); And populating data like this (for example): // Prepare data to populate $data['name'] = 'Naveed'; $data['organization'] = 'ABC'; $data['isAdmin'] = '1'; // Populate editable data $this->view->form->populate( $data ); It is populating data in textboxes but not checking the checkbox? Any idea that how to check a checkbox from action? Thanks

• Net Screen manager setup

  - by Codezy

  I'm having an issue with our NSMExpress box. I'm trying to manage all our devices, range from ns5gt to ssg320m, and some of those devices have addresses assigned by dhcp from the ISP (like pppoe or dsl). The addresses are actually static but we have the register the MAC address in order to get this address. I can actually add the device in NSM except the IP that's on the untrust side isn't imported in as it's dynamic. Because of this I cannot change many options that pertian to the untrust interface as there is no IP. I've talked to JTAC on this and they didn't know if there was a way to do this or not but then they stated that Tim Hortons does this so I'm confused on how to get this working. Maybe i'm just missing something as I imagine that other people must be doing this as well. Any assistance is appreciated! Furthermore when I import a device this is the message I get: Warnings: Interface ethernet0/0 is a pppoe/dhcp/pppoa client and its ip is NOT IMPORTED because it may be dynamic.

• XNA 2D mouse picking

  - by Corndog

  I'm working on a simple 2D Real time strategy game using XNA. Right now I have reached the point where I need to be able to click on the sprite for a unit or building and be able to reference the object associated with that sprite. From the research I have done over the last three days I have found many references on how to do "Mouse picking" in 3D which does not seem to apply to my situation. I understand that another way to do this is to simply have an array of all "selectable" objects in the world and when the player clicks on a sprite it checks the mouse location against the locations of all the objects in the array. the problem I have with this approach is that it would become rather slow if the number of units and buildings grows to larger numbers. (it also does not seem very elegant) so what are some other ways I could do this. (Please note that I have also worked over the ideas of using a Hash table to associate the object with the sprite location, and using a 2 dimensional array where each location in the array represents one pixel in the world. once again they seem like rather clunky ways of doing things.)

• Django | Python creating a JSON response

  - by MMRUser

  Hi, I'm trying to convert a server side AJAX response script in to an Django HttpResponse, but apparently it's not working. This is the server-side script /* RECEIVE VALUE */ $validateValue=$_POST['validateValue']; $validateId=$_POST['validateId']; $validateError=$_POST['validateError']; /* RETURN VALUE */ $arrayToJs = array(); $arrayToJs[0] = $validateId; $arrayToJs[1] = $validateError; if($validateValue =="Testuser"){ // validate?? $arrayToJs[2] = "true"; // RETURN TRUE echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH success }else{ for($x=0;$x<1000000;$x++){ if($x == 990000){ $arrayToJs[2] = "false"; echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH ERROR } } } And this is the converted code def validate_user(request): if request.method == 'POST': vld_value = request.POST.get('validateValue') vld_id = request.POST.get('validateId') vld_error = request.POST.get('validateError') array_to_js = [vld_id, vld_error, False] if vld_value == "TestUser": array_to_js[2] = True x = simplejson.dumps(array_to_js) return HttpResponse(x) else: array_to_js[2] = False x = simplejson.dumps(array_to_js) test = 'Error' return render_to_response('index.html',{'error':error},context_instance=RequestContext(request)) return render_to_response('index.html',context_instance=RequestContext(request)) I'm using simplejson to encode the Python list (so it will return a json array).Coudn't figure out the problem yet.But I think that I did something wrong about the 'echo'. Anyway I'm expecting an good answer it will help me a lot. Thanks.

• Which design is better?

  - by Tattat

  I have an "Enemy" object, that have many "gun" . Each "gun" can fire "bullet". Storing "gun" is using an array. when the "gun" is fired, the "bullet" will be created. And the enemy object will have an array to store the "bullet". So, I am thinking about the fire method. I am think making a firebulletFromGun in the "enemy". It need have a parameter: "gun". while this method is called. The "enemy" 's bullet will be added in the Array. Another design is writing the fire method in the "gun". The "enemy" use the "gun"'s fire method. And the "gun" will return a "bullet" object, and it will be added in the Array of "enemy". Both method can work, but which way is better? or they are similar the same? plx drop ur ideas/suggestions. thz.

• Confused over behavior of List.mapi in F#

  - by James Black

  I am building some equations in F#, and when working on my polynomial class I found some odd behavior using List.mapi Basically, each polynomial has an array, so 3*x^2 + 5*x + 6 would be [|6, 5, 3|] in the array, so, when adding polynomials, if one array is longer than the other, then I just need to append the extra elements to the result, and that is where I ran into a problem. Later I want to generalize it to not always use a float, but that will be after I get more working. So, the problem is that I expected List.mapi to return a List not individual elements, but, in order to put the lists together I had to put [] around my use of mapi, and I am curious why that is the case. This is more complicated than I expected, I thought I should be able to just tell it to make a new List starting at a certain index, but I can't find any function for that. type Polynomial() = let mutable coefficients:float [] = Array.empty member self.Coefficients with get() = coefficients static member (+) (v1:Polynomial, v2:Polynomial) = let ret = List.map2(fun c p -> c + p) (List.ofArray v1.Coefficients) (List.ofArray v2.Coefficients) let a = List.mapi(fun i x -> x) match v1.Coefficients.Length - v2.Coefficients.Length with | x when x < 0 -> ret :: [((List.ofArray v1.Coefficients) |> a)] | x when x > 0 -> ret :: [((List.ofArray v2.Coefficients) |> a)] | _ -> [ret]

• Warning: preg_match() [function.preg-match]: Unknown modifier '/' problem

• I need to load a video stored in Applications folder in to a UITableView ?

  - by srikanth rongali

  I need to load a video stored in Applications folder in to a table view. When I touched the cell the video plays. I used the following code to get all the video files in to an array. NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray* contents = [fileManager directoryContentsAtPath:@"/Users/srikanth/Desktop/Projects/UF/Table2/Videos"]; for(a = 1; a < [contents count]; a++) NSLog(@"Array contents: %@", [contents objectAtIndex:a]); cells = [[NSMutableArray alloc]initWithCapacity:[contents count]]; But how can I load the videos into UITableView. I used NSBundle for loading videos by giving path. It worked. But, now I need the videos to load from the array contents. When I touch the cell of the table the corresponding file from the array contents si to be loaded. How can I make it? Thank you.

• Save static version of a webpage to be available offline

  - by Tal Weiss

  Is there a way to save a webpage as static HTML, available for offline viewing, editing etc.? I want to remove all javascript files. Leave only HTML, CSS and images. For example, if this web page has a Facebook Like button, I want the image of the button to be part of the HTML as a regular image (and not be loaded as some Javascript code runs after I load the page). I'm trying to prepare a webpage for an offline demo. When I use the standard "save as HTML complete" like tools, all the Javascript is saved as well, and when viewed offline, all the dynamic content is blanks. Note- I don't expect the dynamic content to work, of course, with no Javascript. I just want the web page to LOOK as though it was just loaded from the interwebs. Thanks, Tal.

• Choosing my first Domain Registrar?

  - by user36914

  This will be the first domain i've ever registered. So i'm at a loss what to look for. I definitely don't want to go with GoDaddy. Here are my requirements: Must have unlimited email forwards for my domain Easy to transfer away if i choose. Must not be one of those shady registrars that will try to auction your domain at the end. Ability to create sub domains Domain Registration is Private I would like a domain registrar that would let me use my dynamic ip of my ISP (Cable) if i want to. So hopefully they would have some type program that would detect IP changes and update accordingly So i've looked at a variety of registrars so far. The three left were really NameCheap, DreamHost, & DomainMonster. I have heard good things about DreamHost but i think its off the list because they don't give you any information about the features you get when you register your domain with them. They have a "Whats included" button the page but it mainly list the features with hosting not registration. DomainMonster looks pretty cool but i don't see anything about subdomains. Also i would assume they don't have a system for dynamic ip address updating. So you would have to constantly check that your ip of your ISP has changed or not and update it manually. NameCheap also looks nice. There are two things i really like about them. Right on their feature page they list "Free Dynamic DNS With Client" which is pretty cool. They also have a free SSL certificate for the first year. Haven't messed a lot with certificates but this would definitely be something i would use. Only minus i can see is you only get free private whois for the first year. After that its $2.99 which isn't that big of a deal. I'm leaning towards NameCheap now. Is this a good choice. Is there anything else i should be looking at?

• zend_captcha always fails isValid()

  - by Grant Collins

  Hi, I've got an issue with Zend_Captcha always returning false when the page is submitted and the captcha's isValid() method is being called. It's driving my nuts because this as far as I am concerned should work. I start by declaring this at the top of the action function of the controller $captcha = new Zend_Captcha_Image('captcha', array( 'captcha' => array( 'name' => 'graduatesignupcaptcha', 'wordlen' => 6, 'font' => $this->config->captcha->font, 'imgDir' => $baseUrl.'/images/captcha/', 'imgUrl' => $this->config->webserver->name.'/images/captcha/', ) ) ); $captcha->setHeight(80) ->setTimeout(300); I do usual form validation and that all works, however it is when I come to validate that the value entered into form for the captcha it always returns false. //next we check the captcha text to ensure that the form is a person not a script $captchaText = $form->getElement('captchainput')->getValue(); $captchaId = $form->getElement('captchaid')->getValue(); //$captchaSession = new Zend_Session_Namespace('Zend_Form_Captcha_'.$captchaId); $captchaArray = array( 'id' => $captchaId, 'input' => $captchaText ); if(!$captcha->isValid($captchaArray)){ $log->log(implode(",",$captcha->getErrors()), Zend_Log::DEBUG); $form->getElement('captchainput')->setErrors(array('messages' => 'Bad security code')); $formFailed = true; } I've check to ensure that the id that I am getting and storing as a hidden element in my form match the image that is being generated but no matter what I do this always fails. Am I missing something simple here?? Or is there a better way of dealing with this?? Thanks,

• Multiple Application Support Directories for iPhone Simulator?

  - by Alex G

  I am developing an iPhone app with someone else. The app works fine for me, but he is running into a bug. We think this bug is related to the fact that he is getting multiple Application directories for this same app. In my ~/Library/Application Support/iPhone Simulator/User/Applications, I only have one folder at all times. He says that he will get 3 or 4 directories when he is only working on this one app. We think this is our problem because our bug has to do with displaying images that are stored in the app's Documents folder. Does anyone know why he is ending up with multiple directories or how to stop it? Edit: Here is the code for writing the image to a file: NSData *image = [NSData dataWithContentsOfURL:[NSURL URLWithString:[currentArticle articleImage]]]; NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; NSFileManager *NSFM = [NSFileManager defaultManager]; BOOL isDir = YES; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/images"]; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/%@.jpg", [currentArticle uniqueID]]; [image writeToFile:imagePath atomically:NO]; And here is the code for getting the path when I need the image: - (NSString *)imagePath { NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; return [imagePath stringByAppendingFormat:@"/images/%@.jpg", [self uniqueID]]; } The app works great for me, but my partner says that the images don't show up intermittently, and he notices that he gets multiple directories in his Applications folder.

• Passing variables across a multi page form in php

  - by Chris

  Forgive me as I am a newbie. I have a multi page form in which I am using $_SESSIONS to record the variables. <?php session_start(); foreach ( $_POST as $key=>$value ) { if ( $key!="submit" ) { $value= htmlentities(stripslashes(strip_tags($value))); $_SESSION[$key] = $value; } }` I have two problems actually. When I get to a checkform.php that I made that prints out the variables, The variables from page 1 doesn't show up even though that code listed above is on each page. I am using Firefox web developers tool to disable cookies and in the php ini, I altered session.use_trans_sid to 1 to turn it on. For the final page on my checkform.php I print_r($_POST) for the final page which works fine. Why doesn't variables from page 1 not show up? What am I missing? The 2nd problem is that when I print_r($_SESSION), some fields, specifically the checkbox arrays, print as [payment] => Array [agerange] => Array [meals] => Array [mealtypes] => Array What am I missing?

• PHP-FPM Pool, Child Processes and Memory Consumption

  - by Jhilke Dai

  In my PHP-FPM configuration I have 3 Pools, the eg: Config is: ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 1 ; ;;;;;;;;;;;;;;;;;;;;;;; [www1] user = www group = www listen = /tmp/php-fpm1.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 2 ; ;;;;;;;;;;;;;;;;;;;;;;; [www2] user = www group = www listen = /tmp/php-fpm2.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 3 ; ;;;;;;;;;;;;;;;;;;;;;;; [www3] user = www group = www listen = /tmp/php-fpm3.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 I calculated the pm.max_children processes according to some example calculations on the web like 40 x 40 Mb = 1600 Mb. I have separated 4 GB of RAM for PHP, now according to the calculations 40 Child Processes via one socket, and I have total of 3 sockets in my Nginx and FPM configuration. My doubt is about the amount of memory consumption by those child processes. I tried to create high load in the server via httperf hog and siege but I could not calculate the accurate memory usage by all the PHP processes (other processes like MySQL and Nginx were also running). And all the sockets were in use, So, I seek guidance from anyone who have done this before or know how exactly the pm.max_children in PHP Works. Since I have 3 Pools/sockets with 40 child processes does that count to 3 x 40 x 40 Mb of Memory usage ? or it is just like 40 Max. Child processes sharing 3 sockets (and the total memory usage is just 40 x 40 Mb) ?

• Magento- custom attribute causes blank order number.

  - by frank

  Hi- I created a simple custom attribute on the sales/order entity. Now, for new orders, order number is null. I looked at the sales_order table, and sure enough, increment_id is null... can anyone help me out, I am stumped? This is my setup.php: `public function getDefaultEntities() { return array( 'order' => array( 'entity_model' => 'sales/order', //'attribute_model' => 'catalog/resource_eav_attribute', 'table' => 'sales/order', 'attributes' => array( 'pr_email_sent' => array( 'label' => 'prEmailSent', 'type' => 'varchar', 'default' => 'false' ), ) ) ); }` This is my config.xml <fieldsets> <sales_order> <pr_email_sent><create>1</create><update>1</update></pr_email_sent> </sales_order> </fieldsets> Thanks.

• average case running time of linear search algorithm

  - by Brahadeesh

  Hi all. I am trying to derive the average case running time for deterministic linear search algorithm. The algorithm searches an element x in an unsorted array A in the order A[1], A[2], A[3]...A[n]. It stops when it finds the element x or proceeds until it reaches the end of the array. I searched on wikipedia and the answer given was (n+1)/(k+1) where k is the number of times x is present in the array. I approached in another way and am getting a different answer. Can anyone please give me the correct proof and also let me know whats wrong with my method? E(T)= 1*P(1) + 2*P(2) + 3*P(3) ....+ n*P(n) where P(i) is the probability that the algorithm runs for 'i' time (i.e. compares 'i' elements). P(i)= (n-i)C(k-1) * (n-k)! / n! Here, (n-i)C(k-1) is (n-i) Choose (k-1). As the algorithm has reached the ith step, the rest of k-1 x's must be in the last n-i elements. Hence (n-i)C(k-i). (n-k)! is the total number of ways of arranging the rest non x numbers, and n! is the total number of ways of arranging the n elements in the array. I am not getting (n+1)/(k+1) on simplifying.
