37,597,526 | 0 | In jvectormap is there a way to show individual us states on page load? <p>I am new to using jvectormap. I was wondering if there was a way to show individual US states on page load? I have USA drill down map working but need to be able to show specific states such as Colorado for example without having to zoom in from the larger map of the USA. I know there are ways to create your own individual state maps from vector files but just thought I would ask here to see if it was possible to do that using the map that jvector provides for the US before I went through that process. Any help is much appreciated.

6,890,750 | 0 | <p>I can't comment on whether its more effective to use HEAD or trying to do something like drop to the system and do a ping; but I don't think either of them is the solution you should be doing. IMHO, it isn't necessary to poll your connection. There are a lot of situations where a connection could be dropped and I don't think polling will provide much in the way of mitigating the problem. Also, the user might be annoyed. I know that if I were using an application, and then started doing something else, and all of a sudden I got a "connection lost to 3rd party error" from an application I wasn't even paying attention to; I would be very annoyed.</p> <p>If your application depends on a connection being present, then I think its fair to handle this with exception handlers. I'm willing to be bet that whatever API you're using throws some kind of exception whenever you attempt a network action and you aren't able to establish a connection. So, what I would do is in whatever class you're initializing the network action, I would follow this paradigm:</p> <pre><code>try { performNetworkAction(); } catch (NoConnectionFoundException e) { // handle the situation here } </code></pre> <p>Your application shouldn't be able to determine when a connection was lost, just how to react when you attempt a network action and no connection is found.</p> <p>That being said - you still may disagree with me. If that is the case then the frequency of polling allowed/recommended might be documented in the API for the service you're using. Also, if the resource from the 3rd party is static, you should cache it as opposed to getting it over and over again.</p> |

7,457,885 | 0 | <p>All of the answers you've gotten so far are overly complicated and/or slightly misleading.</p> <p>In the first construction/initialization:</p> <pre><code>T a(10); </code></pre> <p>The very obvious thing happens. The second construction/initialization is more interesting:</p> <pre><code>T aa = 10; </code></pre> <p>This is equivalent to:</p> <pre><code>T aa(T(10)); </code></pre> <p>Meaning that you create a temporary object of type T, and then construct <code>aa</code> as a copy of this temporary. This means that the copy constructor is called.</p> <p>C++ has a default copy constructor that it creates for a class when you have none explicitly declared. So even though the first version of <code>class T</code> has no copy constructor declared, there still is one. The one the compiler declares has this signature <code>T(const T &)</code>.</p> <p>Now in your second case where you declare something that looks like a copy constructor, you make the argument a <code>T &</code>, not a <code>const T &</code>. This means that the compiler, when trying to compile the second expression, tries to use your copy constructor, and it can't. It's complaining that the copy constructor you declared requires a non-const argument, and the argument it's being given is const. So it fails.</p> <p>The other rule is that after the compiler has converted your initialization to <code>T aa(T(10));</code> it is then allowed to transform it to <code>T aa(10);</code>. This is called 'copy elision'. The compiler is allowed, in certain circumstances, to skip calls to the copy constructor. But it may only do this after it verifies that the expression is correctly formed and doesn't generate any compiler errors when the copy constructor call is still there. So this is an optimization step that may affect exactly which parts of a program run, but cannot affect which programs are valid and which ones are in error (at least from the standpoint of whether or not they compile).</p> |

9,950,737 | 1 | How to avoid circular dependencies when setting Properties? <p>This is a design principle question for classes dealing with mathematical/physical equations where the user is allowed to set any parameter upon which the remaining are being calculated. In this example I would like to be able to let the frequency be set as well while avoiding circular dependencies.</p> <p>For example:</p> <pre><code>from traits.api import HasTraits, Float, Property from scipy.constants import c, h class Photon(HasTraits): wavelength = Float # would like to do Property, but that would be circular? frequency = Property(depends_on = 'wavelength') energy = Property(depends_on = ['wavelength, frequency']) def _get_frequency(self): return c/self.wavelength def _get_energy(self): return h*self.frequency </code></pre> <p>I'm also aware of an update trigger timing problem here, because I don't know the sequence the updates will be triggered:</p> <ol> <li>Wavelength is being changed</li> <li>That triggers an updated of both dependent entities: frequency and energy</li> <li>But energy needs frequency to be updated so that energy has the value fitting to the new wavelength!</li> </ol> <p>(The answer to be accepted should also address this potential timing problem.)</p> <p>So, what' the best design pattern to get around these inter-dependent problems? At the end I want the user to be able to update either wavelength or frequency and frequency/wavelength and energy shall be updated accordingly.</p> <p>This kind of problems of course do arise in basically all classes that try to deal with equations.</p> <p>Let the competition begin! ;)</p> |

11,952,461 | 0 | <p>Check out e.g. the <a href="http://en.cppreference.com/w/cpp/string/byte/strtok" rel="nofollow"><code>strtok</code></a> function. Use it in a loop to split at the <code>'&'</code> to get all the key-value pairs into a vector (for example). Then go though the vector splitting each string (you can use <code>strtok</code> again here) at the <code>'='</code> character. You can put the keys and values in a <code>std::map</code>, or use directly.</p> <p>For an even more C++-specific method, use e.g. <a href="http://en.cppreference.com/w/cpp/string/basic_string/find" rel="nofollow"><code>std::string::find</code></a> and <a href="http://en.cppreference.com/w/cpp/string/basic_string/substr" rel="nofollow"><code>std::string::substr</code></a> instead of <code>strtok</code>. Then you can put keys and values directly into the map instead of temporary storing them as strings in a vector.</p> <p><strong>Edit:</strong> How to get the last pair</p> <p>The last key-value pair is not terminated by the <code>'&'</code> character, so you have to check for the last pair <em>after</em> the loop. This can be done by having a copy of your string, and then get the substring after the last <code>'&'</code>. Something like this perhaps:</p> <pre><code>char *copy = strdup(data); // Loop getting key-value pairs using `strtok` // ... // Find the last '&' in the string char *last_amp_pos = strrchr(copy, '&'); if (last_amp_pos != NULL && last_amp_pos < (copy + strlen(copy))) { last_amp_pos++; // Increase to point to first character after the ampersand // `last_amp_pos` now points to the last key-value pair } // Must be free'd since we allocated a copy above free(copy); </code></pre> <p>The reason we need to use a copy of the string, if because <code>strtok</code> modifies the string.</p> <p>I still would recommend to you use C++ strings instead of relying on the old C functions. It would probably simplify everything, including you not needing to add the extra check for the last key-value pair.</p> |
