• How to specify a font from javascript?

  - by Steven Lu

  I am trying to customize a view-src bookmarklet for iPad. This one is looking pretty good so far. But I want to make it just a little more readable: The Courier (New) font is a bit ugly even (especially?) on the retina display and I'd prefer any one of DejaVu Sans Mono, Monaco, Lucida Console, Bitstream Vera Sans Mono. I tried to modify the bookmarklet script by adding: pre.style.fontFamily = '"DejaVu Sans Mono", "Lucida Console", Monaco;'; It's not doing the trick. Perhaps prettyprint cancels out my fontFamily setting when it loads. Maybe I can set it at the end of the script somehow...

• Zedgraph textobj X location depends on text length?

  - by Tony_Henrich

  I have a Zedgraph textobj which I want to place always in the same x, y position (ASP.NET image). I noticed that the text doesn't always show in the same starting x position. It shifts depending on the text's length. I tried to have the text to have the same length by padding it with spaces. It helped a little but the result is not always consistent. I am using PaneFraction for coordType. What's the proper method to have a piece of text to always show in the same x position. I am using textobj as a title because the native title property always shows up centered and I need my title be left aligned to the graph.

• Quick backup system for large projects

  - by kamziro

  I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big. Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored. What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)? Or is there any ingenious methods out there that people use?

• Store html form on client or server while building?

  - by Brett

  Hi, I have a fairly complex html form enhanced via jquery. It has multiple tabs, within each one things like a html form builder, uploads, descriptions. There is lots of data, and as the user flicks around the various tabs I'm thinking of posting the data to the server. For example, the form builder, has about 10 properties for each field, as the user flicks between the various fields, an ajax request saves the current values, then loads a new set from the new field clicked on. When the user hits save, the idea is then on the server all these bits and pieces come together and become the live version (i may store them as a temp version while the user is working away). So I guess my question is, for complex forms where the same fields are re-used within the one form, does anyone attempt to save all this data locally and upload it in one hit or do most of you do little ajax post's and compile it all when the final save button is hit? b

• Safe deployment of ASP.Net applications

  - by gatapia

  Hi All, I have an asp.net app that I want to deploy safely (with as little down time possible). I would love to do something like blue green deployment but without the need for a second web server. So, I know I can use load balancing, etc but I need a quick and cheap approach. I was thinking of doing something like: Setting up another website (copy of original) in IIS, currently I use host headers to direct traffic across sites). I could then view the new site locally until the site is totally online (due to NHibernate start up and various other high intensity tasks this takes a while). Once site 2 is totally started I would then change host headers around giving me a much much smaller down time. So my question is. Has anyone done anything like this? Will IIS restart my app pool or application when changing host headers (making this useless)? Any other options? Thanks for your help all. Guido

• Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

  - by Lee Richardson

  I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

• Static Access To Multiple Instance Variable

  - by Qua

  I have a singleton instance that is referenced throughout the project which works like a charm. It saves me the trouble from having to pass around an instance of the object to every little class in the project. However, now I need to manage multiple instances of the previous setup, which means that the singleton pattern breaks since each instance would need it's own singleton instance. What options are there to still maintain static access to the singleton? To be more specific, we have our game engine and several components and plugins reference the engine through a static property. Now our server needs to host multiple game instances each having their own engine, which means that on the server side the singleton pattern breaks. I'm trying to avoid all the classes having the engine in the constructor.

• WPF MVVM Pattern - References

  - by KroaX

  Hi everyone I wanted to know if some of you guys can post some articles, blog posts etc. that explain the MVVM Pattern in detail. There are not much explainations out there I think ( except Tutorials). I'm going to write my exam about WPF and also want to build in the MVVM Pattern. So I need some good references that are also digging a little deeper. I think I already have read a lot of texts about MVVM, but maybe you guys got some I didn't read yet. Would really appreciate if you would share your links to good and worth reading articles and explanations

• language to create flowcharts

  - by robintw

  Hi, This seems like something which must have been answered before, but I can't find anything appropriate in the question archives. Basically, I'm looking for a little Domain Specific Language to create flowcharts. I'm terrible at graphic design and making things look nice, and I'd really like a langauge where I could write something in code and it would produce a pretty flowchart. I've come across GraphViz, but it seems more suited to creating things like Finite State Machine diagrams, rather than process flowcharts. It also doesn't have the simple DSL-style front-end that would allow me to easily work it. Any ideas? I'm sure this must have been done before... Robin

• Adding JTextField to a JPanel and showing them

  - by Davide Gualano

  I'm building a little app using Java and Swing in NetBeans. Using NetBeans design window, I created a JFrame with a JPanel inside. Now I want to dynamically add some jTextFields to the JPanel. I wrote something like that: Vector textFieldsVector = new Vector(); JTextField tf; int i = 0; while (i < 3) { tf = new JTextField(); textFieldVector.add(tf); myPanel.add(tf); //myPanel is the JPanel where I want to put the JTextFields i++; } myPanel.validate(); myPanel.repaint(); But nothing happens: when I run the app, the JFrame shows with the JPanel inside, but the JTextFields don't. I'm a total newbie in writing graphical Java apps, so I'm surely missing something very simple, but I can't see what.

• Cloned Cached item has memory issues

  - by ioWint

  Hi there, we are having values stored in Cache-Enterprise library Caching Block. The accessors of the cached item, which is a List, modify the values. We didnt want the Cached Items to get affected. Hence first we returned a new List(IEnumerator of the CachedItem) This made sure accessors adding and removing items had little effect on the original Cached item. But we found, all the instances of the List we returned to accessors were ALIVE! Object relational Graph showed a relationship between this list and the EnterpriseLibrary.CacheItem. So we changed the return to be a newly cloned List. For this we used a LINQ say (from item in Data select new DataClass(item) ).ToList() even when you do as above, the ORG shows there is a relationship between this list and the CacheItem. Cant we do anything to create a CLONE of the List item which is present in the Enterprise library cache, which DOESNT have ANY relationship with CACHE?!

• Toubleshooting mapkit performance

  - by brettr

  I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

• Does anyone know a better alternative to MS Excel's Solver?

  - by tundal45

  My company has to crunch a lot of data and part of the process involves running the solver and plotting a graph through resulting data points. Obviously there is a lot of copy and paste involved and the whole process is shaky, error prone and all round cluster-fudge. I was wondering if there was an alternative to the solver that can be used so that even if we have to use excel to plot the final graph, there will be a lot less data that needs to be copied and pasted back and forth. It would be great especially if the tool could be easily integrated into a .NET application but I am open to suggestions that may require a little bit of code-fu to get this to work. Thanks!

• How to trace a raw (character) device stream on Unix ?

  - by Fabien

  I'm trying to trace what is transiting in a raw (character) device on an Unix system (ex: /dev/tty.baseband) for DEBUG purpose. I am thinking of creating a deamon that would: upon start rename /dev/tty.baseband to /dev/tty.baseband.old. create a raw node /dev/tty.baseband spawn two threads: Thread 1: reading /dev/tty.baseband.old writing into /dev/tty.baseband Thread 2: reading /dev/tty.baseband writing into /dev/tty.baseband.old This would work a little bit like a MITM process. I wonder if there is not a 'standard' way to do this.

• small javascript problem

  - by dfg

  Hi, I have this little function that opens modal window type thing. The problem is that it doesnt work on IE. All other browser its fine, but on IE, nothing happends: function showOverlayBox() { if( isOpen == false ) return; $('#full').css({ display:'block', left: ( $(window).width() - $('#full').width() )/2, top: ( $(window).height() - $('#full').height() )/2, position:'absolute' }); $('.BgCover').css({ display:'block', width: $(window).width(), height: $(window).height() }); } function doOverlayOpen() { isOpen = true; showOverlayBox(); $('.BgCover').css({opacity:0}).animate( {opacity:0.8} ); return false; } function doOverlayClose() { $('#full').css( 'display', 'none' ); $('.BgCover').animate( {opacity:0}, null, null, function() { $(this).hide(); } ); } Maybe something to do with isOpen == false?

• J2ME HTTPS Connection Problem: Certificate was issued by an unrecognized entity

  - by Mustafa

  I am developing a little J2ME application that will read our grades from our university's server. With Desktop Applications, It is fine, I can do it but in J2ME, it always gives me this error, even I use well-known services like HTTPS Google, I still get the same error. urlConn = (HttpsConnection) Connector.open("https://stars.bilkent.edu.tr/srs/ajax/login.php"); urlConn.setRequestMethod(HttpsConnection.POST); urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); o = urlConn.openOutputStream(); // Sending my POST requests to server input = urlConn.openDataInputStream(); In the last line I always get the error I mentioned above. What should I do about it?

• How do you authenticate user generated "apps" for your app?

  - by Brian Armstrong

  I'm think something like Facebook apps here. User generated pieces of code that people can write to interact with my app. I understand how an authenticated API works, but this seems a little more complicated because not only does the APP have to authenticate itself (with a regular api-key) but the USER using the app has to be authenticated somehow too, without giving the app free reign. I've been reading a bit here to see how FB does it: http://wiki.developers.facebook.com/index.php/How_Facebook_Authenticates_Your_Application And it looks like you have to pass a signature in addition to the api-key along with every call, but I'm having trouble wrapping my head around how this gets generated and used on the other end (my server). Figure there must be a simple explanation of this out there? Thanks! P.S. I'm building a Rails app if there are any applicable gems/plugins.

• What would be the disadvantages/risks of using AF_UNSPEC?

  - by Kiril Kirov

  From Beej's Guide to Network programming You can force it to use IPv4 or IPv6 in the ai_family field, or leave it as AF_UNSPEC to use whatever. This is cool because your code can be IP version-agnostic. As the title says - what would be the disadvantages (or risks, if any) of always using AF_UNSPEC, instead of specifying IPv4 or IPv6? Or it's only for one reason - if the version is specified, this will guarantee that this and only this version is supported? A little background - I think about adding support for IPv6 in client-server (C++) applications and both versions should be supported. So I wondered if it's fine to use AF_UNSPEC or it's better to "recognize" the address from the string and use AF_INET6 or AF_INET, depending on the address.

• Are rems replacing ems in CSS?

  - by Kevin

  I was reading about rem units in CSS3, and was a little confused. If you use rem, do you still use em or does that replace it? For example: .selector { margin-bottom:24px; margin-bottom:2.4rem; font-size:16px; font-size:1.6rem; } or .selector { margin-bottom:24px; margin-bottom:2.4em; margin-bottom:2.4rem; } Just trying to figure out if rem takes the place of em, or if it's just another unit.

• Struts2 dynamic form elements

  - by bozo

  Hi, I would like to create little higer-level framework on top of Stuts2 which can take form element description from Action and render a complete form, in order to avoid having a separate JSP files with hardcoded form elements for every form in a large web application (so if I manage to do this I will have just a few generic JSPs for data form and few for layout). Application is extremely data-driven. My idea is to create form description using custom objects in the Action (i.e. Button, TextInput etc.) and then to create a single JSP page that will render eveything out. What is the best way of doing this? Can you propose some concrete way to do this? I don't want to write something if I can reuse the existing code with some effort. Any ideas are appreciated. Kind regards, Bozo

• Drupal Views pulling Data Fields

  - by askon

  I'm a little new to drupal but have been using things like devel module and theme developer to speed up the learning process. My question, is it possible to theme an entire views BLOCK from a single views tpl.php page OR even a preprocess? When I'm grabbing the $view object I can see results $node-result, it has all of the results, but it doesn't have all my views fields. I'm missing things like, node path, taxonomy titles and paths, etc. From my understanding, Drupal wants you to individually theme EACH output field. It seems rather superfluous to create so many extra templates when I've already got over HALF of my results coming through the $view object Would outputting node over field make this easier? Or am going in the wrong direction with $view-result? Thanks!

• Close button during modal sheet

  - by Nano8Blazex

  In Objective C (Cocoa) I have an app running with a modal sheet, but I want to allow the app to quit even when the sheet is displayed (contradicting the definition of modal I think, but I like the animated effect of modal sheets). I'm already using the -setPreventsApplicationTerminationWhenModal method and it works fine, but I'm wondering... is there any way to keep the close button enabled? The little circle usually red-colored close button that comes with all windows in the top left corner (side by side with minimize and maximize)? Right now it's completely disabled when the sheet is running, and it would be awesome if there is a way to enable it. Thanks!

• Better way to clean this messy bool method

  - by Luís Custódio

  I'm reading Fowler Clean Code book and I think that my code is a little messy, I want some suggestions: I have a simple business requirement that is return the date of new execution of my Thread. I've two class fields: _hour and _day. If actual day is higher than my _day field I must return true, so I'll add a month to "executionDate" If the day is the same, but the actual hour is higher than _hour I should return true too. So I did this simple method: private bool ScheduledDateGreaterThanCurrentDate (DateTime dataAtual) { if (dateActual.Day > _day) { return true; } if (dateActual.Day == _day && dateActual.Hour > _hour) { return true; } if (dateActual.Day == _day && dateActual.Hour == _hour) if (dateActual.Minute>0 || dateActual.Second>0) return true; return false; } I'm programming with TDD, so I know that the return is correct, but this is bad maintain code right?

• Ruby and Forking

  - by Cory

  Quick question about Ruby forking - I ran across a bit of forking code in Resque earlier that was sexy as hell but tripped me up for a few. I'm hoping for someone to give me a little more detail about what's going on here. Specifically - it would appear that forking spawns a child (expected) and kicks it straight into the 'else' side of my condition (less expected. Is that expected behavior? A Ruby idiom? My IRB hack here: def fork return true if @cant_fork begin if Kernel.respond_to?(:fork) Kernel.fork else raise NotImplementedError end rescue NotImplementedError @cant_fork = true nil end end def do_something puts "Starting do_something" if foo = fork puts "we are forking from #{Process.pid}" Process.wait else puts "no need to fork, let's get to work: #{Process.pid} under #{Process.ppid}" puts "doing it" end end do_something

• Whats faster in Javascript a bunch of small setInterval loops, or one big one?

  - by RobertWHurst

  Just wondering if its worth it to make a monolithic loop function or just add loops were they're needed. The big loop option would just be a loop of callbacks that are added dynamically with an add function. adding a function would look like this setLoop(function(){ alert('hahaha! I\'m a really annoying loop that bugs you every tenth of a second'); }); setLoop would add the function to the monolithic loop. so is the is worth anything in performance or should I just stick to lots of little loops using setInterval?
