• Executing javascript during redirect without changing original referrer

  - by git-noob

  I need to test whether or not a click-through is valid by using some javascript client-side tests (e.g., browser window dimensions). However, I would like the original click referrer to remain the same. Is there a way I can do a redirect, execute some javascript, capture the browser details and then continue the click-through while keeping the original referrer value the same?

• How to know when MKPinAnnotationView pin callout opens/closes

  - by JOM

  I want to update pin callout (popup) subtitle either realtime, when I receive some new info from server, or at least when callout opens. So far it looks like pin + callout are created only once at... - (MKAnnotationView *)mapView:(MKMapView *)aMapView viewForAnnotation:(id <MKAnnotation>)annotation ...and then used as-is as long as it exists regardless how many times I tap it closed/open or scroll around keeping it visible. How can I update the subtitle?

• Emulating Windows Photo Viewer image dragging in c#

  - by murasaki5

  Hi, i'm trying to emulate how image is being dragged inside the windows photo viewer when it is large. The problem is, i don't how to drag the image while keeping it intact in the form's edges. If you're observing windows photo viewer, when you drag the image downward for instance the image moves and stops when the top end of the image is visible, but in my app, it continues to move since i don't know how to check when to stop it.

• Software development working from home

  - by johnhilbron

  Hi, Do you all think that working from home is the wave of the future for software development? In this day and age it seems like a logical next step for software developers to work from their homes and connect to each other using IM, video chat and phone. Etc, etc... What forces are in action pushing software development in this direction? What forces are keeping more people from working remotely? John

• Convert array of hashes to array of structs?

  - by keruilin

  Let's say I have two objects: User and Race. User has two attributes: first_name, last_name. And Race has three attributes: course, start_time, end_time. Now let's say I create an array of hashes like this: user_races = races.map{ |race| {:user = race.user, :race = race} } How do I then convert user_races into an array of structs, keeping in mind that I want to be able to access the attributes of both user and race from the struct element?

• Implement Semi-Round-Robin file which can be expanded and saved on demand

  - by ircmaxell

  Ok, that title is going to be a little bit confusing. Let me try to explain it a little bit better. I am building a logging program. The program will have 3 main states: Write to a round-robin buffer file, keeping only the last 10 minutes of data. Write to a buffer file, ignoring the time (record all data). Rename entire buffer file, and start a new one with the past 10 minutes of data (and change state to 1). Now, the use case is this. I have been experiencing some network bottlenecks from time to time in our network. So I want to build a system to record TCP traffic when it detects the bottleneck (detection via Nagios). However by the time it detects the bottlenecking, most of the useful data has already been transmitted. So, what I'd like is to have a deamon that runs something like dumpcap all the time. In normal mode, it'll only keep the past 10 minutes of data (Since there's no point in keeping a boat load of data if it's not needed). But when Nagios alerts, I will send a signal in the deamon to store everything. Then, when Naigos recovers it will send another signal to stop storing and flush the buffer to a save file. Now, the problem is that I can't see how to cleanly store a rotating 10 minutes of data. I could store a new file every 10 minutes and delete the old ones if in mode 1. But that seems a bit dirty to me (especially when it comes to figuring out when the alert happened in the file). Ideally, the file that was saved should be such that the alert is always at the 10:00 mark in the file. While that is possible with new files every 10 minutes, it seems like a bit dirty to "repair" the files to that point. Any ideas? Should I just do a rotating file system and combine them into 1 at the end (doing quite a bit of post-processing)? Is there a way to implement the semi-round-robin file cleanly so that there is no need for any post-processing? Thanks Oh, and the language doesn't matter as much at this stage (I'm leaning towards Python, but have no objection to any other language. It's less of an issue than the overall design)...

• Setting up a common perl/cpan environment

  - by zedoo

  Hi, so I'm having a lot of fun with Perl at home for some time now. How much more difficult do things get when you develop Perl modules (In my case it's mostly catalyst) in a team? How do we make sure we all got the same development environment (Perl/Module versions)? Simply by keeping up to date with CPAN? Do some teams setup their 'private' CPANs?

• NSTimer as a self-targeting ivar.

  - by Matt Wilding

  I have come across an awkward situation where I would like to have a class with an NSTimer instance variable that repeatedly calls a method of the class as long as the class is alive. For illustration purposes, it might look like this: // .h @interface MyClock : NSObject { NSTimer* _myTimer; } - (void)timerTick; @end - // .m @implementation MyClock - (id)init { self = [super init]; if (self) { _myTimer = [[NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:@selector(timerTick) userInfo:nil repeats:NO] retain]; } return self; } - (void)dealloc { [_myTimer invalidate]; [_myTImer release]; [super dealloc]; } - (void)timerTick { // Do something fantastic. } @end That's what I want. I don't want to to have to expose an interface on my class to start and stop the internal timer, I just want it to run while the class exists. Seems simple enough. But the problem is that NSTimer retains its target. That means that as long as that timer is active, it is keeping the class from being dealloc'd by normal memory management methods because the timer has retained it. Manually adjusting the retain count is out of the question. This behavior of NSTimer seems like it would make it difficult to ever have a repeating timer as an ivar, because I can't think of a time when an ivar should retain its owning class. This leaves me with the unpleasant duty of coming up with some method of providing an interface on MyClock that allows users of the class to control when the timer is started and stopped. Besides adding unneeded complexity, this is annoying because having one owner of an instance of the class invalidate the timer could step on the toes of another owner who is counting on it to keep running. I could implement my own pseudo-retain-count-system for keeping the timer running but, ...seriously? This is way to much work for such a simple concept. Any solution I can think of feels hacky. I ended up writing a wrapper for NSTimer that behaves exactly like a normal NSTimer, but doesn't retain its target. I don't like it, and I would appreciate any insight.

• Exception Handling in SQl Stored Procedures?

  - by Rishabh Ohri

  Hi All, Adding Exceptional Handling is a good practise, but I have a doubt, In our database we have 10 SPs which are accessed by our data access layer, there is not much logic and the queries are also not big.The purpose of keeping the queries in SPs was to allow paged data to be easily passed to the presentation layer. So, my question is, should error handling be added to the SPs in this scenario when they do not include large complex queries?

• Java API with which I can manipulate and modify HTML code and its tags?

  - by Catfish

  Is there a 3rd party API for the sole purpose with which I can replace relative URLs in the source HTML and CSS into absolute URLs, keeping in mind the fact that the source contains a mix of relative and absolute URLs. For those thinking twice about this question, the String Object's replaceAll() method has some shortcomings.

• Recommendations for project management software for Scrum

  - by Mendokusai

  We're using Scrum on our current project and we're very happy using our agile board and cards but reporting, burndown charts etc. are somewhat cumbersome to maintain. So, we're looking for good agile software to use instead. I'm keeping requirements deliberately vague but does anyone have any recommendations? The software would need to run on Windows.

• Perl, print with newline

  - by Mike

  In perl most of my print statements take the form print "hello." . "\n"; Is there a nice way to avoid keeping all the pesky "\n"s lying around? I know I could make a new function such as myprint that automatically appends \n, but it would be nice if I could override the existing print.

• DRY URL's in Django Javascript

  - by Noio

  I'm using Django on Appengine. I'm using the django reverse() function everywhere, keeping everything as DRY as possible. However, I'm having trouble applying this to my client-side javascript. There is a JS class that loads some data depending on a passed-in ID. Is there a standard way to not-hardcode the URL that this data should come from? var rq = new Request.HTML({ 'update':this.element, }).get('/template/'+template_id+'/preview'); //The part that bothers me.

• delete all but minimal values, based on two columns in SQL Server table

  - by sqlill

  how to write a statement to accomplish the folowing? lets say a table has 2 columns (both are nvarchar) with the following data col1 10000_10000_10001_10002_10002_10002 col2 10____20____10____30____40_____50 I'd like to keep only the following data: col1 10000_10001_10002 col2 10____10____30 thus removing the duplicates based on the second column values (neither of the columns are primary keys), keeping only those records with the minimal value in the second column. how to accomplish this?

• How to reduce size of BIRT generated PDF with background image?

  - by Yishai

  It seems (at least that is our understanding of the issue at this point) that given a background image in BIRT, the PDF generation routine repeats the image information inside the PDF instead of having it once referenced as the background image of all pages of the PDF. This causes our BIRT generated PDFs to be too large. Is there a way to get BIRT to only store the image once inside the PDF and have it be the background image on each page of the PDF while keeping the file size more reasonable?

• Hidden WCF endpoints

  - by Matt

  For the sake of arguement, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

• Member variable pointers to COM objects

  - by drelihan

  Hi Folks, Is there any problem with keeping member variable pointer refernces to COM objects and reussing the reference through out the class in C++. Is anybody aware of a reason why you would want to call .CreateInstance every time you wanted a to use the COM object i.e. you were getting a fresh instance each time. I cannot see any reason who you would want to do this, Thanks, (No is an acceptable answer!!!)

• Scalable Ticketing / Festival Website

  - by Luke Lowrey

  I've noticed major music festivals (at least in Australia) and other events that experience a peak in traffic when tickets go on sale have huge problems keeping their websites running well. I've seen a few different techniques used to try combat this such as short sessions and virtual queues but they dont seem to have much effect. If you were to design a website to sell a lot of tickets in a short amount of time how would you handle scalability? What technologies and programming techniques would you use?
