  • Simple 2 column CSS layout with nested divs

    - by Dan
    Hello, I have good familiarity with CSS but for some reason I am unable to achieve the result I want in this case. Here is the link to my test site http://danberinger.com/test.html Keep in mind that I want a 2 column layout and that the background wrapper color (gray) is not showing. Instead the body background color image is being put in place of where the wrapper background should be. Any suggestions would be greatly appreciated.

  • How can I access IEnumerable<T> extension methods on my custom subclass of BindingList<T>?

    - by Dan
    I have a custom subclass of BindingList<T> that I want to execute a LINQ query over using the handy extension methods. For example: public int GetSum(MyList<T> list) { return list.Sum(x => x.Value); } But the compiler complains that it can't resolve Sum because it doesn't recognize list as an IEnumerable<T>, which it obviously is, because this works: public int GetSum(MyList<T> list) { return ((IEnumerable<T>)list).Sum(x => x.Value); } Anyone have a clever way I can avoid the ugly and unecessary cast?

  • Resources for finding Haskell jobs?

    - by Dan
    Where is a good place to go to find a job where I can (frequently) use Haskell? Just to be clear, I am not asking: What's the Haskell market like? Why is Haskell used so little in the industry? What is Haskell actually useful for? Nor am I asking you to tell me that Haskell jobs can't be found. That is the default conclusion if no good responses show up here. I am asking, for the 2 or 3 Haskell jobs that are out there, how can I find them?

  • Best language for scripting large scale file management

    - by Dan
    The National Park Service's Natural Sounds Program collects multiple terabytes of data each year measuring soundscapes. In your opinion, what is best available scripting language to manage massive amounts of files and file types? We would like to easily design and run efficient user-friendly scripts to search for and retrieve/create copies of files that may be located in different directories according a single static hierarchy. The OS will most likely be windows. Thanks!

  • How can I specify my own Rhino context in Java?

    - by Dan Howard
    I'm trying to ensure that my Rhino scripts (running under Java 6) are strict so that if a script developer misspells an expression I want an exception to be thrown. Currently what happens is the expression simply evaluates to "undefined". Now according to Mozilla org https://developer.mozilla.org/en/New_in_Rhino_1.6R6 there are features to enable strict checking in the context. I cannot find a working example of this. What I did so far was write a class to extend ContextFactory and then override the hasFeature method. public class ScriptContextFactory extends ContextFactory { protected boolean hasFeature(Context context, int featureIndex) { switch (featureIndex) { case Context.FEATURE_STRICT_EVAL: return true; case Context.FEATURE_STRICT_VARS: return true; } return super.hasFeature(context, featureIndex); } } Then in the Main I set mine to the default. ContextFactory.initGlobal(new ScriptContextFactory()); and I get an illegal state exception. :( Any ideas or samples on how this works? TIA

  • Starting company and getting a good deal

    - by Dan
    Hi, I'm having the possibility to start a small company with someone else. I'm a software programmer and been working on a field where there isn't much competition, at least in the platform I'm developing, which is the one with highest market share. This other person comes from marketing so he would find / provide clients and be in charge of the business side. So initially it would be me, the tech guy with the knowledge to develop our product and products based on my development, and this person who would become CEO (basically a 50/50 share). The idea is getting a product on our own, but also perform projects for others in order to get some cash. The problem is that his idea is doing this without initial capital. He tells me that he could get some customers from past business (which is mostly true as he has been in the business for some time) and then with the money obtained from such development, we could hire some freelance developers and build our own platform. I've already discussed with him that I don't find this the best way, provided that we need to compete against other companies some of who are VC funded and have many developers working fulltime. But most of all, I'm thinking of whether this is a fair deal to do, provided that this person is not providing anything other than clients, and I'd be the one having to do the work and dedicate time, thus also taking most of the risks. In all fairness, I'd expect him to put some initial capital, given that initially I'm putting some of my code which in some way is money given the time I've dedicated to it. So the question here is, does this seem fair to you? Is this the way it is usually done? My only concern here is that I don't have previous experience with such deals, and I ignore whether this is the usual thing to do in other cases. Certainly having a marketing person helps a lot. As you probably know being a programmer doesn't make me the most indicated person for marketing ;-) but at the same time I'm not sure if this could be a good deal or I'd just be making a pretty inconvenient deal. Hope I made my point clear, but feel free to let me know if more details are needed. Thanks in advance

  • C# Breakpoint Weirdness

    - by Dan
    In my program I've got two data files A and B. The data in A is static and the data in B refers back to the data in A. In order to make sure the data in B is invalidated when A is changed, I keep an identifier for each of the links which is a long byte-string identifying the data. I get this string using BitConverter on some of the important properties. My problem is that this scheme isn't working. I save the identifiers initially, and with I reload (with the exact same data in A) the identifiers don't match anymore. It seems the bit converter gives different results when I go to save. The really weird thing about it is, if I place a breakpoint in the save code, I can see the identifier it's writing to the file is fine, and the next load works. If I don't place a breakpoint and say print the identifiers to console instead, they're totally different. It's like when my program is running at full-speed the CPU messes up some instructions. This isn't the first time something like this happens to me. I've seen it in other projects. What gives? Has anyone every experienced this kind of debugging weirdness? I can't explain how stopping the program and not stopping it can change the output. Also, it's not a hardware problem because this happens on my laptop as well.

  • Integrating YUI tests with CruiseControl

    - by Dan R
    I am using YUI to test my JavaScript app, and want to integrate the test results into my CruiseControl build system. How can I use CruiseControl to run the tests? I initially thought about using the JUnit plugin to drive the tests, but that is a no go. Does anyone else have this working? (Please note: Changing either YUI or CruiseControl isn't an option for me.)

  • Eclipse jvm.dll error when loading

    - by Dan James Palmer
    Trying to open Eclipse after a couple of months and get this error: So I checked that folder to see if it existed, and it did: I checked my PATH Was correct and it was also correct: When this error first occurred I had 3 Java installations. JRE 7 Update 10, JDK 7 Update 7 32bit and 64 bit. I uninstall ALL and restarted my machine. Eclipse then stated, as expected that I needed a JRE or a JDK. So I downloaded and installed the latest JDK and now I get this error, despite everything appearing to be correct. Any ideas?

  • What ellipsoid or geoid for GPX file elevations-and how do you know?

    - by Dan Menes
    I have been poking around and have been unable to find a standard for what ellipsoid or geoid corresponds to "0" elevation in GPX files. Is there a standard? Do I just assume the WGS84 ellipsoid? Or if different standards are used, is there a way of figuring out from the file which one was used? Or making an educated guess? And what is the source for your answer? I would love to have an authoritative reference.

  • Python - List of Lists Slicing Behavior

    - by Dan Dobint
    When I define a list and try to change a single item like this: list_of_lists = [['a', 'a', 'a'], ['a', 'a', 'a'], ['a', 'a', 'a']] list_of_lists[1][1] = 'b' for row in list_of_lists: print row It works as intended. But when I try to use list comprehension to create the list: row = ['a' for range in xrange(3)] list_of_lists = [row for range in xrange(3)] list_of_lists[1][1] = 'b' for row in list_of_lists: print row It results in an entire column of items in the list being changed. Why is this? How can I achieve the desired effect with list comprehension?

  • How do I get the WVGA Android browser to stop scaling my images?

    - by Dan Fabulich
    I'm designing an HTML page for display in Android browsers. Consider this simple example page: <html> <head><title>Simple!</title> </head> <body> <p><img src="http://sstatic.net/so/img/logo.png"></p> </body> </html> It looks just fine on the standard HVGA phones (320x480), but on HDPI WVGA sizes (480x800 or 480x854) the built-in browser automatically scales the image up; it looks ugly. I've read that I should be able to use this tag to force the browser to stop scaling my page: <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;" /> ... but all that does is disable user scaling (the zoom buttons disappear); it doesn't actually prevent the browser from scaling my image. Adjusting the scale factors (setting them all to 2.0 or 0.5) has no effect at all. How can I force the WVGA browser to stop scaling my images?

  • Is there a cleaner way to Bind property to owner's DataContext?

    - by Dan Bryant
    I have some code that looks like this: <Expander Header="{Binding SelectedSlot.Name}" Visibility="{Binding ShowGroupSlot, Converter={StaticResource BooleanToVisibility}}"> <Controls:GroupPrototypeSlotControl Slot="{Binding DataContext.SelectedSlot, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Expander}}}" /> </Expander> This works, but the ugliness of the Slot Binding bothers me. This is required because the GroupPrototypeSlotControl has a GroupPrototypeViewModel as its DataContext. If I simply use {Binding SelectedSlot}, it attempts to resolve it on the 'child' ViewModel, which fails. I get around this by explicitly looking at the DataContext of my parent control. Is there a cleaner way to do this type of binding?

  • Where about should my main class be created in a project?

    - by Dan
    The problem is where a class should be created in my code. An example is I have a UI class and a main logic class that controls other objects. Should the main logic class create the UI object, or should the UI object create the instance of the main logic class? An explanation of which method is best and why would be ideal. Thanks.

  • How to jQuery plugin effects to items created later in the DOM

    - by Dan Denney
    How do I apply jQuery plugin effects to items that are created by an event? So, what I am attempting to do is have all uls throughout a site use the jquery.scroll.js plugin for styling. I currently have it working on all active uls. However, there are some category/subcategory sections. I am still new to writing any jQuery on my own and there is a leap in logic that I don't understand on applying plugins to items when they are loaded later. In the real example, users click a category from a ul and a sub category is loaded via Rails and JSON. For a light sample, I made a jsfiddle that simulates the issue that I run into. The category ul is styled correctly, but the subcategory ul doesn't pick up the styling. I'm hoping for some assistance not just in whipping up some code to fix it, but in pointing me in the direction of what I need to learn for this functionality. http://jsfiddle.net/dandenney/25R8F/1/ Thank you in advance!

  • Oracle - Updating one column or another based on a condition

    - by z-dan
    I want to update a record in a table but based on a condition I will either update one column or another but I do not want to have 2 separate statements because the statements are very long and detailed. Here is the basic idea with over simplification to get to the point. PROCEDURE Animal_something(p_updater VARCHAR2) begin if p_updater = 'person' then -- I want to update the modified_by else -- if p_updater = 'a process' I want to update modified_by_process Update table_creatures set animal_type = 'Dog , **modified_by** = 'Bob' **or do this** **modified_by_process =** 'creature_package' where animal_legs = '4' I don't want: if p_updater = 'person' then Update table_creatures set animal_type = 'Dog , modified_by = 'Bob' where animal_legs = '4'; else Update table_creatures set animal_type = 'Dog , modified_by_process = 'creature_package' where animal_legs = '4'; end;

  • Is hardware accelerated CSS3 in Safari 4 & 5 broken, or my CSS and JS?

    - by Dan Forys
    Hi all, I've created a somewhat silly site that shows you the expected weather forecast for any city in the World. On webkit based browsers, when the weather is sunny a sun with CSS3 animated rotated sunbeams appears. This works fine on Chrome. An example (sunny, at the moment) page is: http://willitraintoday.co.uk/iceland/reykjavik/ However, when viewed in Safari 4 or 5 on Mac Snow Leopard, when the sun appears the sky background appears over it. Weirder still, as the cloud containing the advert moves across the sky, it squashes the main text. When the cloud reaches the left edge, the text appears wider than normal and starts squashing down again. I've tried: - Disabling the CSS3 animation; it works fine in Safari - Juggling the z-index of various elements; to no avail Is there something up with my Javascript or CSS, or is the hardware accelerated snow leopard Safari broken in this case? It seems not to happen in Safari 4 on Leopard, but I don't have Leopard any more to test myself. Grateful for any opinions!

  • WCF RIA Services v1.0 Timeouts

    - by Dan Wray
    I have a RIA service methods which return quite a large amount of (binary) data to my silverlight application. The methods themselves (database access etc) complete quickly, but since I upgraded to v1.0 from the RC2 I've been experiencing timeouts, even when I limit the data returned to the smallest objects. Debug shows the method returning, then 20-30 seconds later the silverlight "method complete" event will fire. There is not enough data to cause that much lag. Could anyone suggest why this might be? I've been unable to find any breaking changes documentation specific to the RC2 = 1.0 upgrade. Trying to eliminate any other possible causes also, but this is literally a case of worked before the install, doesn't work now! (also upgraded silverlight 4 tools for vs).

  • iphone: cross platform references and referencing external framework resources

    - by dan
    hi there working on an iphone app and separate framework. the separate framework is for an API that i'm building for use in multiple future apps. this api now needs to reference resources (images). what i would like to do is keep the resources WITH the API framework as local set of resources. i followed the instructions from http://www.clintharris.net/2009/iphone-app-shared-libraries/ to setup my app's project to use the headers from the separate API framework. what i can't seem to figure out is how to automatically load the framework's resources into the app's xcode environment so they can be linked in at app compile time. sure, i can drag the resources across from the framework into the main app's set of resources. but that seems kinda ugly and another step that possibly can be automated (??) anyone know of a better way? it would be great if any changes from the framework would be automatically available in the main app (due to the project 'link-age'). thanks for any help/tips/suggestions...

  • Is nested synchronized block necessary?

    - by Dan
    I am writing a multithreaded program and I have a method that has a nested synchronized blocks and I was wondering if I need the inner sync or if just the outer sync is good enough. public class Tester { private BlockingQueue<Ticket> q = new LinkedBlockingQueue<>(); private ArrayList<Long> list = new ArrayList<>(); public void acceptTicket(Ticket p) { try { synchronized (q) { q.put(p); synchronized (list) { if (list.size() < 5) { list.add(p.getSize()); } else { list.remove(0); list.add(p.getSize()); } } } } catch (InterruptedException ex) { Logger.getLogger(Consumer.class.getName()).log(Level.SEVERE, null, ex); } } } EDIT: This isn't a complete class as I am still working on it. But essentially I am trying to emulate a ticket machine. The ticket machine maintains a list of tickets in the BlockingQueue q. Whenever a client adds a ticket to the machine, the machine also keeps track of the price of the last 5 tickets (ArrayList list)

  • Cannot Translate to SQL using Select(x => Func(x))

    - by Dan
    I'm slowly learning the ins and outs of LINQtoSQL, but this is confusing me. Here is the statement I have: IQueryable<IEvent> events = (from e in db.getEvents() select e).Select(x => SelectEvent(x, null)); What the SelectEvent does can be explained in this answer here. I am not using the .toList() function as I don't want potentially thousands of records brought into memory. public IEvent SelectEvent(SqlServer.Event ev, EventType? type) { // Create an object which implements IEvent // I don't have the code in front of me, so forgive the lack of code } My question is really for the Select() method. I get the "Cannot translate to SQL" error and the Select() is listed in the error message. Clueless on this one :-/.
