5,740,505 | 0 | <p>As other people have said, you need to implement a comparison function yourself.</p> <p>There is a proposed way to ask the compiler to generate the obvious/naive(?) implementation: see <a href="http://www.open-std.org/Jtc1/sc22/wg21/docs/papers/2014/n4126.htm" rel="nofollow">here</a>.</p> <p>It may seem a bit unhelpful of C++ not to have already Standardised this, but often structs/classes have some <strong>data members to exclude</strong> from comparison (e.g. counters, cached results, container capacity, last operation success/error code, cursors), as well as <strong>decisions to make</strong> about myriad things including but not limited to:</p> <ul> <li>which fields to compare first, e.g. comparing a particular <code>int</code> member might eliminate 99% of unequal objects very quickly, while a <code>map<string,string></code> member might often have identical entries and be relatively expensive to compare - if the values are loaded at runtime, the programmer may have insights the compiler can't possibly</li> <li>in comparing strings: case sensitivity, equivalence of whitespace and separators, escaping conventions...</li> <li>precision when comparing floats/doubles</li> <li>whether NaN floating point values should be considered equal</li> <li>comparing pointers or pointed-to-data (and if the latter, how to know how whether the pointers are to arrays and of how many objects/bytes needing comparison)</li> <li>whether order matters when comparing unsorted containers (e.g. <code>vector</code>, <code>list</code>), and if so whether it's ok to sort them in-place before comparing vs. using extra memory to sort temporaries each time a comparison is done</li> <li>how many array elements currently hold valid values that should be compared (is there a size somewhere or a sentinel?)</li> <li>which member of a <code>union</code> to compare</li> <li>normalisation: for example, date types may allow out-of-range day-of-month or month-of-year, or a rational/fraction object may have 6/8ths while another has 3/4ers, which for performance reasons they correct lazily with a separate normalisation step; you may have to decide whether to trigger a normalisation before comparison</li> <li>what to do when weak pointers aren't valid</li> <li>how to handle members and bases that don't implement <code>operator==</code> themselves (but might have <code>compare()</code> or <code>operator<</code> or <code>str()</code> or getters...)</li> <li>what locks must be taken while reading/comparing data that other threads may want to update</li> </ul> <p>So, it's kind of <strong>nice to have an error</strong> until you've explicitly thought about what comparison should mean for your specific structure, <strong>rather than letting it compile but not give you a meaningful result at run-time</strong>.</p> <p>All that said, it'd be good if C++ let you say <code>bool operator==() const = default;</code> when you'd decided a "naive" member-by-member <code>==</code> test <em>was</em> ok. Same for <code>!=</code>. Given multiple members/bases, "default" <code><</code>, <code><=</code>, <code>></code>, and <code>>=</code> implementations seem hopeless though - cascading on the basis of order of declaration's possible but very unlikely to be what's wanted, given conflicting imperatives for member ordering (bases being necessarily before members, grouping by accessibility, construction/destruction before dependent use). To be more widely useful, C++ would need a new data member/base annotation system to guide choices - that would be a great thing to have in the Standard though, ideally coupled with AST-based user-defined code generation... I expect it'll happen one day.</p> <h2>Typical implementation of equality operators</h2> <h3>A plausible implementation</h3> <p>It's <em>likely</em> that a reasonable and efficient implementation would be:</p> <pre><code>inline bool operator==(const MyStruct1& lhs, const MyStruct1& rhs) { return lhs.my_struct2 == rhs.my_struct2 && lhs.an_int == rhs.an_int; } </code></pre> <p>Note that this needs an <code>operator==</code> for <code>MyStruct2</code> too.</p> <p>Implications of this implementation, and alternatives, are discussed under the heading <em>Discussion of specifics of your MyStruct1</em> below.</p> <h3>A consistent approach to ==, <, > <= etc</h3> <p>It's easy to leverage <code>std::tuple</code>'s comparison operators to compare your own class instances - just use <code>std::tie</code> to create tuples of references to fields in the desired order of comparison. Generalising my example from <a href="http://stackoverflow.com/a/37269108/410767">here</a>:</p> <pre><code>inline bool operator==(const MyStruct1& lhs, const MyStruct1& rhs) { return std::tie(lhs.my_struct2, lhs.an_int) == std::tie(rhs.my_struct2, rhs.an_int); } inline bool operator<(const MyStruct1& lhs, const MyStruct1& rhs) { return std::tie(lhs.my_struct2, lhs.an_int) < std::tie(rhs.my_struct2, rhs.an_int); } // ...etc... </code></pre> <p>When you "own" (i.e. can edit, a factor with corporate and 3rd party libs) the class you want to compare, and especially with C++14's preparedness to deduce function return type from the <code>return</code> statement, it's often nicer to add a "tie" member function to the class you want to be able to compare:</p> <pre><code>auto tie() const { return std::tie(my_struct1, an_int); } </code></pre> <p>Then the comparisons above simplify to:</p> <pre><code>inline bool operator==(const MyStruct1& lhs, const MyStruct1& rhs) { return lhs.tie() == rhs.tie(); } </code></pre> <p>If you want a fuller set of comparison operators, I suggest <a href="http://www.boost.org/doc/libs/1_60_0/libs/utility/operators.htm" rel="nofollow">boost operators</a> (search for <code>less_than_comparable</code>).

This would definitely leave <code>MyStruct1::an_int</code> set to the constructor's default parameter value of <code>-1</code>. Depending on whether you include <code>an_int</code> comparison in the implementation of your <code>operator==</code>, a <code>MyStruct1</code> might or might not compare equal to a <code>MyStruct2</code> that itself compares equal to the <code>MyStruct1</code>'s <code>my_struct_2</code> member! Further, creating a temporary <code>MyStruct1</code> can be a very inefficient operation, as it involves copying the existing <code>my_struct2</code> member to a temporary, only to throw it away after the comparison. (Of course, you could prevent this implicit construction of <code>MyStruct1</code>s for comparison by making that constructor <code>explicit</code> or removing the default value for <code>an_int</code>.)</p> <p><strong>Member implementation</strong></p> <p>If you want to avoid implicit construction of a <code>MyStruct1</code> from a <code>MyStruct2</code>, make the comparison operator a member function:</p> <pre><code>struct MyStruct1 { ... bool operator==(const MyStruct1& rhs) const { return tie() == rhs.tie(); // or another approach as above } }; </code></pre> <p>Note the <code>const</code> keyword - only needed for the member implementation - advises the compiler that comparing objects doesn't modify them, so can be allowed on <code>const</code> objects.</p> <h2>Comparing the visible representations</h2> <p>Sometimes the easiest way to get the kind of comparison you want can be...</p> <pre><code> return lhs.to_string() == rhs.to_string(); </code></pre> <p>...which is often very expensive too - those <code>string</code>s painfully created just to be thrown away! For types with floating point values, comparing visible representations means the number of displayed digits determines the tolerance within which nearly-equal values are treated as equal during comparison.</p> |

33,927,174 | 1 | Django reverse url to onetoonefield on success <p>Good day SO!</p> <p>Recently I've started working on Django, got myself a situation which I can't find the right solution on the web to solve it. So I've got a little question about URL reversing on a success. Currently when an user successfully creates an account, the user gets reversed to a profile based on the user_id which just got created: </p> <pre><code>class Create(CreateView): form_class = UserCreateForm # inherits from django's UserCreationForm def get_success_url(self): return reverse('users:profile', kwargs={'pk': self.object.pk}) </code></pre> <p>This is working properly. Now I created a profile module with a OneToOneField to the django.auth.models User model. When creating a new account, a signal is send to the create_profile_on_registration method.</p> <pre><code>@receiver(post_save, sender=User) def create_profile_on_registration(sender, created, instance, **kwargs): ... </code></pre> <p>This is also working properly, a new profile is created on user account registration. Now I would like to reverse the user to the new created profile_id instead of the user_id. However, I cant figure out exactly how to get this properly to work. Can you give me a little push in the right direction on how to approach this issue? I can't match up the right google search words or find any examples which explains or shows how to achieve this properly.</p> <p>Thanks in advance!</p> |

5,358,680 | 0 | <p>Yes, that is a much more complicated task. You're going to have to store the last modified time into a database (since you're saying users can modify their profile content I'll assume you already have a database). The easiest way to get the last time the user modified their profile depends on your schema.</p> <p>To put it another way... what the user is actually modifying isn't "profile.php", it's some data that lives elsewhere, e.g. a MySQL database; so the system that's going to know when the user last modified it is that external data source.</p> |

22,663,157 | 0 | <p>Overdispersion isn't really a useful concept in the normal model because it is already fitting a variance for the variability at the observation level. So the error message is telling you that you can't have a grouping factor at the observation level. In that sense, yes, you are trying to overfit your model.</p> <p>In a poisson (or other glm) model, however, it does make sense, because the variability at the observation level is fixed according to whatever the variance term in the glm is, so it does make sense to add an additional variance term to the model to account for any extra variability at the observation level. Hence <code>glmer</code> does not do the same check that <code>lmer</code> does.</p> |

3,161,587 | 0 | SSRS - How can I conditionally send a report to a mail address <p>Let me specify the environment. The client has UI for entering orders in SQL Server database. A Windows Service one another machine is processing these orders from database at particular intervals. Sometimes the Windows service is stopped then orders piles up. To avoid that I have created a SQL Server Report which is run at an interval of 5mins. It checks how many orders are processed and creates a status report. What I want, if count of processed order is zero then the report be mailed to system administrator. Then he will check the machine where the service is hosted and restart the service, so that all rework is avoided. So the question is how to implement this conditional delivery of report. In short, if count is zero no report be mailed otherwise it must.</p> |
35,399,107 | 0 | <p>Got it! Incredibly simple when you add a container node.

12,011,482 | 0 | <p>Whatever is not implemented in the Linux kernel, you have to implement yourself or borrow from another open source kernel module.

Specifically the <a href="http://www.kernel.org/doc/htmldocs/kernel-api/libc.html">Basic C Library Functions</a> section for your general question, and the <a href="http://www.kernel.org/doc/htmldocs/kernel-api/ch02s02.html">String Manipulation</a> section for your specific question about <code>strcat</code>.</p> <p>You'll want to include <code>linux/string.h</code>.</p> <p>I don't know why the kernel API documentation doesn't actually show the header file that you have to include to get the function.

15,074,850 | 0 | <p>It's not that you can't access "primitive values" by reference. The problem is that some data types in Python are mutable (lists, dictionaries) while others are immutable (integers, strings, tuples). Whenever you try to modify an immutable object, you always get back a new object with the new value. The original object remains untouched. So...</p> <pre><code>a = 3 # create a new object with the value 3 and bind it to the variable 'a' b = a # bind the variable 'b' to the same object as 'a' </code></pre> <p>Here both 'a' and 'b' are referencing the same object at the same location in memory. However, because the object is immutable, modifying 'b' does not have the "expected" result...</p> <pre><code>b = 4 print a # displays "3" </code></pre> <p>Those of us coming from C/C++ aren't used to "immutable objects". In C, you would expect "b = 4" to modify the "object" b is pointing to, setting its value to 4. In Python, this isn't the case. "b = 4" creates a new object whose value is 4 and modifies b so that it points to this new object.</p> |

40,550,961 | 0 | <p>Those specific pieces of information aren't necessarily available in any sort of direct way using the xAPI (Tin Can API). xAPI stores data points in a stream of statements, those statements <em>may</em> include some of that information depending on how and what generated them.</p> <p>To access the statement stream you would need to make xAPI requests to the <code>/statements</code> resource provided by the LRS. You would have to ask the individual vendors for the location of their xAPI "endpoint" and for information on credentials for accessing that endpoint. Once you have that information I would suggest using one of the open source libraries linked at <a href="http://experienceapi.com/libraries" rel="nofollow noreferrer">http://experienceapi.com/libraries</a> to interface with the LRS. A lot of additional information about what xAPI provides, how to use it, etc. is available at that site.</p> |

11,236,200 | 0 | Why do we need a static lock for synchronizing system.out.println()? <p>I am studying for java certification, and I see this example from Mughal's book:</p> <pre><code>public class Smiley extends Thread { @Override public void run() { while(true) { synchronized(this) { try { System.out.print(":"); Thread.sleep(100); System.out.print("-"); Thread.sleep(100); System.out.println(")"); Thread.sleep(100); } catch(InterruptedException e) { e.printStackTrace(); } } } } public static void main(String[] args) { new Smiley().start(); new Smiley().start(); } } </code></pre> <p>The purpose is to print one smiley :-) per line. My question is that why synchronizing on instance (this) doesn't achieve this? Why we need to synchronize on static level?</p> <p>Thanks,</p> |

13,424,483 | 0 | <p>When you open a MongoDB connection with the native driver, you're actually opening a pool of 5 connections (by default). So it's best to open that pool when your app starts and just leave it open rather than open and close the pool on each request.</p> <p>You're on the right track with closing out your HTTP response; just call <code>res.end();</code> when the response is complete (i.e. when <code>item</code> is <code>null</code> in the <code>cursor.each</code> callback).</p> |
