• What's the most auditable way to organize database maintenance scripting/scheduling?

  - by RenderIn

  I'm using PHP, Oracle and crontab. Crontab is invoking a php script, which is going to synchronize some data between a local and remote database. First I thought about putting this all in one large, anonymous inline PL/SQL block and executing it in PHP. The problem is that without creating a table to audit the procedure it's really opaque to my PHP code until it returns. And then when it does return, the best I can do is receive a string in an out parameter which I've concatenated together as an audit log. Then I considered breaking it up into several SQL statements and have PHP do some intermediate auditing/logging and manipulation of the data between each of them. I'm not really satisfied with either of these. How do you organize maintenance code that is called in a cronjob?

• IE display problem

  - by bah

  Hi, I have a page, and I just added pagination to it, but there's a prob in IE 7 & 8. When I add pagination code echo "<div class='pagination'>"; echo $pagination->GetPageLinks(); echo "</div>"; it breaks somehow layout in IE, I have looked all over it and I couldn't find what's wrong there. oh, and its css div.pagination { text-align : center; } div.pagination a, div.pagination span { padding : 5px; display : inline-block; } page url - adelija.puslapiai.lt, it's on index page, if you could take a look, that'd be great.

• 3 div independently relative and top aligned

  - by Knu

  I have 3 div top aligned that should be relative to a previous div (not between them so i can't use floats or position:inline-block either). If you set display:none on 2 divs the last one shouldn't move. I can't use position:absolute because there's a relative footer underneath. I tried using a wrapper but it can't work cause the height of the divs is not fixed. The height of the wrapper gets completely ignored anyway (by the following footer) unless Im using relative children. vertical-align:top doesn't work either. Any ideas?

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• Should i use lock.lock(): in this method?

  - by user962800

  I wrote this method whose purpose is to give notice of the fact that a thread is leaving a specific block of code A thread stands for a car which is leaving a bridge so other cars can traverse it . The bridge is accessible to a given number of cars (limited capacity) and it's one way only. public void getout(int diection){ // release the lock semaphore.release(); try{ lock.lock(); //access to shared data if(direction == Car.NORTH) nNordTraversing--; //decreasing traversing threads else nSudTraversing--; bridgeCond.signal(); }finally{ lock.unlock(); } } My question is: should I use lock.lock(); or it's just nonsense? thanks in advance

• Why doesn't BlackBerry let me click on this link?

  - by Steve N

  This is a link in an HTML email.. Other links in this email work, but this one does not get recognized in a BlackBerry as a link, so you can't click on it. Does anyone know why that might be? Here's the markup for it: <a title="Continue" style="display: block; width:200px; border:1px solid #336699; text-align: center; padding-top:5px; padding-bottom:5px; font-size:14px; font-family: Arial, Sans-Serif; color:#336699; font-weight:bold; text-decoration: none;" href="https://www.mydomain.com/mypage.aspx?id=8430650">Continue ››</a>

• Java static source analysis/parsing (possibly with antlr), what is a good tool to do this?

  - by Berlin Brown

  I need to perform static source analysis on Java code. Ideally, I want the system to work out of the box without much modification from me. For example, I have used Antlr in the past, but I spent a lot of time building grammar files and still didn't get what I wanted. I want to be able to parse a java file and have return the character position of say: Character position start and end of a Java block comment Character position start and end of a Java class file Character position start and end of a Java method declaration, signature, and implementation. It looks like Antlr will do that, but I have yet to finish a grammar that actually gives me the positions of the code I need. Does anyone have that complete Antlr grammar and Java code to give the character positions of the parts in the Java source.

• Rails controller processing as HTML instead of XML

  - by Andy

  I've recently upgraded from Ruby 1.8.6 and Rails 2.3.4 to Ruby 1.9 and Rails 3.0.3. I have the following controller: class ChartController < ApplicationController before_filter :login_required respond_to :html, :xml def load_progress chart.add( :series, "Memorized", y_memorized ) chart.add( :series, "Learning", y_learning ) chart.add( :series, "Mins / Day", y_time ) chart.add( :user_data, :secondary_y_interval, time_axis_interval ) respond_to do |fmt| fmt.xml { render :xml => chart.to_xml } end # Also tried # respond_with chart end end However, when I call the 'load_progress method' I get the following: Started GET "/load_progress.xml" for 127.0.0. Processing by ChartController#load_progress as HTML Completed 406 Not Acceptable in 251ms I have also tried changing the respond_to block to respond_with chart But I get the same response. I've read all the new Rails documentation on the new respond_with format but I can't seem to elicit an XML response. Am desperately hoping someone has some ideas.

• Java - Confused by the one class per file rule

  - by Mark

  The one class per file rule in Java has me a bit confused. I writing an Android app and trying to implement the accepted answer to this question: Common class for AsyncTask in Android? which calls for an interface definition which class A implements and class B accepts as an argument to its constructor. So I need an A.java and a B.java, but where does the interface go? Does it need a separate java file itself? Do I have to define it inside both A and B? If not how to import it? Also I will have about 10 different AsyncTask classes, but I don't want to bother creating a new file for each one. What would you recommend? Is there a way to put all 10 classes in one file? Or should I create a big if/then block inside the class and pass an argument telling it which of the 10 different tasks I want it to do?

• .htaccess: RewriteCond syntax?

  - by Rosarch

  I'm using Drupal 6. Typically, when the user requests a URL for which Drupal has no response, it uses index.php as the error document. However, I'd like to suspend this behavior for a specific URL. How can I do this? RewriteCond %{REQUEST_FILENAME} !=fail RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] Where "fail" is the path I want to block. So www.example.com/fail should result in a 404. Incidentally, what does [L, QSA] do? I've looked at documentation without luck.

• padding not shifting my logo

  - by paul smith

  I have a logo link that's using a background-image (css sprite). All works fine, but when I try to add a 20px padding to the top of the link (to give it more space for user to click the link), the background image is not moving down. Here is my css: a { background-image:url("sprite.png"); background-repeat:no-repeat; display:block; height:70px; width:70px; padding-top:20px; /* give top of the link more click space */ } And my html: <a href="#" style="background-position:0 0;"></a> What am I doing wrong?

• javascript really strange behaviour

  - by teehoo

  I have the following code if (msg.position == 0) //removed for brevity else if (msg.position == txtArea.value.length) //removed for brevity } else { //ERROR: should not reach here. errorDivTag.innerHTML += msg.position + " " + txtArea.value.length; } I'm having some really weird situations where I'm getting the error in the last code block, but the printed positions show that msg.position is in fact equal to the txtArea.value.length. This only happens 1% of the time, almost as if I have some kind of race-condition in my code where the two are NOT equal during the second if statement, but equal when I print in the error message. Any ideas?

• jQuery - Programmatically Trigger Event

  - by Sonny

  I need to programmatically trigger a click event that's being handled by jQuery. Here's the current code: var $thumbs = $('#PhotoGalleryThumbs .tile'); var $zoom = $('#PhotoGallery #PhotoGalleryZoom img'); var $description = $('#PhotoGallery #PhotoGalleryDescription'); $thumbs.click(function(event) { event.preventDefault(); var $thumb = $(this); $thumb.addClass('selected') .siblings().removeClass('selected'); $zoom.attr('src', $thumb.children('a').attr('href')); $description.html($thumb.find('img').attr('alt')); }); I am having a mental block working out how to create a function out of the event handling code and then arbitrarily calling it for an element in the $thumbs object.

• How to setup custom CSS based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• lexers / parsers for (un) structured text documents

  - by wilson32

  There are lots of parsers and lexers for scripts (i.e. structured computer languages). But I'm looking for one which can break a (almost) non-structured text document into larger sections e.g. chapters, paragraphs, etc. It's relatively easy for a person to identify them: where the Table of Contents, acknowledgements, or where the main body starts and it is possible to build rule based systems to identify some of these (such as paragraphs). I don't expect it to be perfect, but does any one know of such a broad 'block based' lexer / parser? Or could you point me in the direction of literature which may help?

• When is NSEnumerator finished?

  - by samfu_1

  How do we know when enumeration is finished? The docs say: the return value of nextObject is nil when all objects have been enumerated. I was hoping to implement some "delegate-like" behavior whereby ... if (nextObject == nil) { do something because we're done! } But I see there is no such thing as: enumerationDidFinish: where in the following block could I check for the enumerator to be complete? NSArray *anArray = // ... ; NSEnumerator *enumerator = [anArray objectEnumerator]; id object; while ((object = [enumerator nextObject])) { // do something with object... }

• Doubt about a particular pattern of Javascript class definition

  - by fenderplayer

  Recently i saw the following code that creates a class in javascript: var Model.Foo = function(){ // private stuff var a, b; // public properties this.attr1 = ''; this.attr2 = ''; if(Model.Foo._init === 'undefined'){ Model.Foo.prototype = { func1 : function(){ //...}, func2 : function(){ //... }, //other prototype functions } } Model.Foo._init = true; } // Instantiate and use the class as follows: var foo = new Model.Foo(); foo.func1(); I guess the _init variable is used to make sure we don't define the prototypes again. Also, i feel the code is more readable since i am placing everything in a function block (so in oop-speak, all attributes and methods are in one place). Do you see any issues with the code above? Any pitfalls of using this pattern if i need to create lots of classes in a big project?

• How to display icons next to a select1 control with xxforms:tree appearance

  - by user557060

  Hi, I display a list of items via select1 control using xxforms:tree appearance. They are displayed via a code block like: <xforms:itemset nodeset="instance('dataInstance')/*"> <xforms:label ref="fn:concat(./NAME,', ','ID: ',./ID)"/> <xforms:value ref="./ID"/> </xforms:itemset> </xforms:select1> I want to display two icons for each item on the same row as the item: one icon for deleting and one for editing that item, which would all invoke XPL with the item ID as the parameter. The question, how do I render those icons - does itemset support nested trigger elements? If not, how do I go about achieving it (clicking on the item results in an action other than edit or delete, so cannot use that; can show delete/edit on the page shown when user clicks on the item, but want to save that one click if the user just wants to delete the item for example). Thanks.

• When is it a good idea to use the CSS display property?

  - by allyourcode

  I think I first learned of this property when I thought "I should put this list of items in a ul, but I want it to be laid out horizontally. I wonder if I can do that with CSS?" When I googled this, I found a couple of sites suggesting that I create a CSS rule that would change the value of the display property of the li elements to inline. I've also seen the suggestion that a div (or other block element) be given display: table-cell in order to force the vertical align property to work. These techniques seem kind of hacky. Does that make sense? This might not be a good analogy, but it seems like trying to ride a car as if it were a motorcycle. Yeah, I could replace the steering wheel with handle bars, wear a helmet, and remove all the passenger seating, but how the heck is a car going to drive on two wheels??

• iPhone animation with stretchable image

  - by ryyst

  I got a UIView subclass that draws a UIImage as its background. The image is created using the stretchableImageWithLeftCapWidth:topCapHeight: method, it has round edges. I also use an animation block inside of which I resize my view. I had hoped that during animation, the drawRect:method would get called sometimes, which would result in the background image getting drawn correctly. Unfortunately, the animation seems to render the image and then just rescale it during the animation, which obviously makes the formerly round edges getting nastily stretched. The only workaround I can imagine is put three separate UIImageViews (top cap, middle fill, bottom cap) above my original background image and then reposition the caps images and scaling the fill image. However, this seems quite complicated... Is there any better way I can prevent this from happening?

• How to keep a floating div centered on window resize (jQuery/CSS)

  - by Jimbo

  Is there a way (without binding to the window.resize event) to force a floating DIV to re-center itself when the browser window is resized? To help explain, I imagine the pseudocode would look something like: div.left = 50% - (div.width / 2) div.top = 50% - (div.height / 2) UPDATE My query having been answered below, I wanted to post the final outcome of my quest - a jQuery extension method allowing you to center any block element - hope it helps someone else too. jQuery.fn.center = function() { var container = $(window); var top = -this.height() / 2; var left = -this.width() / 2; return this.css('position', 'absolute').css({ 'margin-left': left + 'px', 'margin-top': top + 'px', 'left': '50%', 'top': '50%' }); } Usage: $('#mydiv').center();

• Application_EndRequest Dosent Fire on a 404

  - by Shane

  I am using ASP MVC 2 and Nhibernate. I have created an HTTP Module as demonstrated in Summer of NHibernate 13 that looks like so: public void Init(HttpApplication context) { context.PreRequestHandlerExecute += new EventHandler(Application_BeginRequest); context.PostRequestHandlerExecute += new EventHandler(Application_EndRequest); } private void Application_BeginRequest(object sender, EventArgs e) { ISession session = StaticSessionManager.OpenSession(); session.BeginTransaction(); CurrentSessionContext.Bind(session); } private void Application_EndRequest(object sender, EventArgs e) { ISession session = CurrentSessionContext.Unbind(StaticSessionManager.SessionFactory); if (session != null) try { session.Transaction.Commit(); } catch (Exception) { session.Transaction.Rollback(); } finally { session.Flush(); session.Close(); } } web.config <add name="UnitOfWork" type="HttpModules.UnitOfWork"/> My problem is that Application_EndRequest never gets called on a 404 error so if my view does not render I completely block database access until my flush takes place. I am fairly new to NHibernate so I am not sure if I am missing something.
