12,240,084 | 0 | <p>AFAIK, there is no direct answer because multiple wavelengths can combine to give the same color right? So you have the wavelengths that map to pure colors and then their combinations can give many other and the same colors. And there are several combinations that can give the same color. This is because of inteference. So you essentially are asking for a one to many mapping. </p> <p>To answer your question: There is no fixed formula. The reverse formulas will give you a range. That is the best it can get. </p> |

315,940 | 0 | <p>Documentation is a tricky term since it involves different artifacts and different tasks, what do you mean by documentation?</p> <p>User manuals? Screensteps can be used for that. Most companies hire special technical writers to do user-friendly documentation.</p> <p>Function headers and API documentation? That's a different story. The "official" guideline (at least for Java) is to capture everything - complete specifications. The agile approach is to document only what's important. I published a study that shows that detailed header documentations tend to actually distract users. There is a relatively small list of important "directives" and "caveats" that need to be conveyed. PM me or send me a comment if you want more details on that and I'll detail more. I'm avoiding it now since I'm not sure what you meant. </p> <p>I also had a tool that lets you record a narrative of what you do as you work, and it ties it to a log of your edits and actions, that establishes some traceability though it's of course not documentation.</p> |

37,264,603 | 0 | <p>First, you'll need a query that is supplying the values for your parameter.

35,375,466 | 0 | Binding data to ListView to display distance to nearby place using Google Places API with UWP <p>Currently, I have a project to display nearby places with UWP using Google Places API.

I have DataTemplate like this</p> <pre><code><DataTemplate x:Key="ResultPlaces"> <StackPanel Orientation="Vertical"> ... <Grid Grid.Column="2"> <TextBlock Text="{Binding placeDistance}" Foreground="#42424c" TextWrapping="Wrap" FontSize="12" Margin="10,0,0,0"/> </Grid> </Grid> </StackPanel> </code></pre> <p>And i also have the ListView like this</p> <pre><code><ListView Name="listPlace" ItemTemplate="{StaticResource ResultPlaces}"> </ListView> </code></pre> <p>I've parsing the JSON in result of API in code behind and make it to be my ListView.ItemsSource. The problem is the API don't provide distance object. So, I created a method to calculte distance between 2 places and use it to calculate every single result in API results. I'm also created get set property called placeDistance in class Result that provided API items result.</p> <p>This my get set property </p> <pre><code> public class Result { .... public Review[] reviews { get; set; } public int user_ratings_total { get; set; } public string placeDistance { get; set; } } </code></pre> <p>And this my code to calculate every single distance on Result</p> <pre><code>int lengthResult = placesList.results.Count(); for (int i = 0; i < lengthResult; i++) { double myLat = placesList.results[i].geometry.location.lat; double myLong = placesList.results[i].geometry.location.lng; double myCurrentLat = Convert.ToDouble(parameters.lat); double myCurrentLong = Convert.ToDouble(parameters.longit); var newDistance = new Result(); newDistance.placeDistance = DistanceBetweenPlaces(myCurrentLong, myCurrentLat, myLong, myLat); } </code></pre> <p>When I deployed it into my phone, the other items in DataTemplate display correctly.

6,303,906 | 0 | <p>The answer is 1/4. Here is the explanation.</p> <p>Let x is the length of the leftmost stick and y is the length of the rightmost stick. Then the middle stick has length n-x-y, if the original stick's length was n.</p> <p>The possible values for x,y are those for which:</p> <ol> <li>x > 0</li> <li>y > 0</li> <li>x + y < n</li> </ol> <p>In the plane Oxy this is equivalent to say that the point (x,y) lies within the triangle with vertices (0, 0), (n, 0), (0, n).</p> <p>Now these three numbers (x, y, n-x-y) form a triangle if all of the three are satisfied:</p> <ol> <li>x + y > n - x - y <=> x + y < n/2</li> <li>x + (n - x - y) > y <=> y < n/2</li> <li>y + (n - x - y) > x <=> x < n/2</li> </ol> <p>Again in the Oxy plane these are satisfied when the point (x,y) lies within the triangle with vertices (0, n/2), (n/2, n/2), (n/2, 0).</p> <p>The area of this triangle is a quarter of the area of the (0, 0), (n, 0), (0, n) triangle, since it's the 'middle' triangle (whose vertices are the midpoints) of the bigger one.</p> <p>Here is a simple C# program to verify the answer:</p> <pre><code>Random r = new Random(); int count = 0, total = 0, tries = 1000000; double x, y; for (int i = 0; i < tries; i++) { x = r.NextDouble(); y = r.NextDouble(); if (x + y > 0.5 && x < 0.5 && y < 0.5) ++count; if (x + y < 1.0) ++total; } Console.WriteLine((double)count / total); </code></pre> |

12,213,317 | 0 | <p>Some code would be useful. In the absence of that here's a best guess generic answer: In general terms you will need to work out how to map (convert) each format to the other. Then you can convert to the format suitable for the database before you save and convert from database format to google maps format when you retrieve. I imagine each polygon is a set of latitude/longitude pairs in both formats so it shouldn't be too difficult.</p> <p>Alternatively, since you're using JSON, you could just save the JSON to a text field in the database (or to a JSON field in the upcoming 9.2 release of PostgreSQL): </p> <p><a href="http://www.postgresql.org/docs/9.2/static/datatype-json.html" rel="nofollow">http://www.postgresql.org/docs/9.2/static/datatype-json.html</a></p> <p>However if you would like to perform geographical queries in the database that would obviously limit your options.</p> |

My problem is that I want to listen out for a hitTestObject of 'square' intercepting 'square' and subsequent additions of the same MovieClip.</p> <p>I've set up a numerical variable that increments up by 1 each time I add the group of 'square' MovieClips through left click to the stage and I've assigned this number along with a string to combine together to create a square.name instance.</p> <p>In my case the first group of MovieClips added would have a .name instance called 'Square 1' and then 'Square 2' on the second mouse click and so on.</p> <p>I've also added and pushed each name through into a container array for referencing later.</p> <p>So how can I actually reference these dynamic names in a hitTestObject argument using my .name instance and array??</p> <p>I'm sure it is obvious and I've done the groundwork so any help to point this out to me would be greatly appriciated.</p> <p>Many Thanks.</p> |

7,840,310 | 0 | Android Maps API Key Issues <p>I am having a weird problem with a simple map application I am trying to write (API 2.2). Yesterday, I started the app and I could see the map displayed and was able to pan around and zoom in and out. It worked perfectly. I also ran the app successfully on a Galaxy tab (I normally run them on an emulator). Today, I started the application, but instead of seeing the map, I see a grid of grey boxes. I thought it might be a problem with the API key, so I created a second one and swapped it with the first, this did not fix the problem.</p> <p>The only difference between the times I tried running the projects was that I did it on two different computers. It worked originally on the computer that I created the project on, but it now will no longer work on any computer that I have attempted to use. I don't know that this is related, but it is the only significant thing that changed between when I ran the project each time.</p> <p>After looking through the LogCat, I have found two errors that might be relevant to my problem they are:</p> <p>Could not open GPS configuration file /etc/gps.conf<br/> Couldn't get connection factory client</p> <p>Does anyone know if these are problems, and if so, how to fix them?</p> |

22,360,300 | 0 | <p>First, you should use explicit <code>join</code> syntax. Second, it is suspicious whenever you have a <code>top</code> without an <code>order by</code>. So, your query as I see it is:</p> <pre><code>select TOP 1 @TopValue = t2.myDecimal from table1 t1 join table2 t2 on t1.ID = t2.table1ID where CONVERT( VARCHART(8), t1.Created, 112 ) = @stringYYYYMMDD and t1.Term = @Label" </code></pre> <p>You can speed this up with some indexes. But, before doing that, you want to change the date comparison:</p> <pre><code>where t1.Created >= convert(datetime, @stringYYYYMMDD, 112) and t1.Created < convert(datetime, @stringYYYYMMDD, 112) + 1 and t1.Term = @Label </code></pre> <p>Moving the function from the column to the constant makes the comparison "sargable", meaning that indexes can be used for it.</p> <p>Next, create the indexes <code>table1(Term, Created, Id)</code> and <code>table2(table1Id)</code>. These indexes should boost performance.</p> |

My JSON looks like below.</p> <pre><code>{"engagementid":1,"clientname":"fsdfs","myno":"23,45","address1":"fsd","address2":"fsdfs","city":"fsdfs","zip":"fsdf","info":"fsdfs","country":"fsdfs","currency":"NOK"} </code></pre> <p>You can see that my "myno" is sent as a string. But in my Server Data Model "myno" is a double value. So what happen here is when I send the value for "myno" as "23,45", it gets assigned to MyNo property of my Model as 2345. This is wrong, because you can see that the number has been changed because of this wrong conversion. What I simply need is to restrict this conversion. I mean, I want to send an error to Client if he sends a string for "myno" property. Since it is a double value in my Server Data Model, I want to accept only numbers from the client for this property. Which means, I want it like this.</p> <pre><code>{"myno":2345} //correct {"myno":"2345"} //wrong. I want to send a error to user by saying, "We only accept Numbers for this value" </code></pre> <p>How do I do this?</p> <p>Update: This problem gets solved if I am using int in my server-model. I mean, if a client send a string to a property which is represented as int in my model, then it gives an error to user by saying string to int conversion can not be done.</p> |

25,743,133 | 0 | Are stack float array ops faster than heap float ops on modern x86 systems? <p>On C float (or double) arrays small enough to fit in L1 or L2 cache (about 16k), and whos size I know at compile time, is there generally a speed benefit to define them within the function they are used in, so they are stack variables? If so is it a large difference? I know that in the old days heap variables were much slower than stack ones, but nowadays with the far more complicated structure of cpu addressing and cache, I don't know if this is true. </p> <p>I need to do repeated runs of floating point math over these arrays in 'chunks', over and over again over the same arrays (about 1000 times), and I wonder if I should define them locally. I imagine keeping them in the closest / fastest locations will allow me to iterate over them repeatedly much faster but I dont understand the implications of caching in this scenario. Perhaps the compiler or cpu is clever enough to realize what I am doing and make these data arrays highly local on the hardware during the inner processing loops without my intervention, and perhaps it does a better job than I can at this. </p> <p>Maybe I risk running out of stack space if I load large arrays in this way? Or is stack space not hugely limited on modern systems? The array size can be defined at compile time and I only need one array, and one CPU as I need to stick to a single thread for this work.</p> |

By picking an element that is guaranteed to be present at the time the delegated event handler is attached, you can use delegated events to avoid the need to frequently attach and remove event handlers.</strong> This element could be the container element of a view in a Model-View-Controller design, for example, or document if the event handler wants to monitor all bubbling events in the document. The document element is available in the head of the document before loading any other HTML, <strong>so it is safe to attach events there without waiting for the document to be ready.</strong></p> </blockquote> <p>Taken from: <a href="http://api.jquery.com/on/">http://api.jquery.com/on/</a></p> |
