Can somebody tell me what's wrong?</p> |

For example: </p> <ul> <li>you will have to move shared properties to the base class</li> <li>you will probably have to maintain some mappings manually in EDMX (at least I had when I did the sample on screenshot)</li> <li>you will have only single <code>ObjectSet<Tasks></code> and you will have to use <code>OfType</code> to query only Projects or Services</li> <li>you will have to use unique Id per <code>Task</code> = across both Project and Service tables (can be achieved by correctly configured identities in database)</li> </ul> <p>It will look like:</p> <p><img src="https://i.stack.imgur.com/kNZrC.png" alt="enter image description here"></p> <p>Another option is using interface on your entity objects instead of parent class. You can define interface in your partial part of entity object and handle retrieving both Projects and Services by yourselves where your UI will expect only list of types implementing your interface.</p> |

30,182,767 | 0 | <p>When using <code>get_template_part</code>, the first parameter defines the base template name (e.g. <code>content</code>, which loads <code>content.php</code>) and the second parameter loads a suffixed version if available. Therefore your call</p> <pre><code>get_template_part('content', 'single-ourNews'); </code></pre> <p>is looking for a file named <code>content-single-ourNews.php</code> first, then falls back to <code>content.php</code> in case the first one is not available. I'm not sure whether the <code>get_template_part</code> function converts the suffix parameter to something like <code>single-ournews</code> or <code>single-our-news</code> before appending it to the first parameter, be sure to test a few variants of that.</p> <p>I'm not 100% sure if the function behaves differently or not in child themes and parent themes.

7,662,456 | 0 | <p>From the <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2011/n3242.pdf" rel="nofollow">C++ Standard ( Working Draft )</a>, section 5 on binary operators</p> <blockquote> <p>Many binary operators that expect operands of arithmetic or enumeration type cause conversions and yield result types in a similar way. The purpose is to yield a common type, which is also the type of the result. This pattern is called the usual arithmetic conversions, which are defined as follows: — If either operand is of scoped enumeration type (7.2), no conversions are performed; if the other operand does not have the same type, the expression is ill-formed. — If either operand is of type long double, the other shall be converted to long double. — Otherwise, if either operand is double, the other shall be converted to double. — Otherwise, if either operand is float, the other shall be converted to float.</p> </blockquote> <p>And also section 4.8</p> <blockquote> <p>A prvalue of floating point type can be converted to a prvalue of another floating point type. If the source value can be exactly represented in the destination type, the result of the conversion is that exact representation. If the source value is between two adjacent destination values, the result of the conversion is an implementation-defined choice of either of those values. Otherwise, the behavior is undefined</p> </blockquote> <p>The upshot of this is that you can avoid unnecessary conversions by specifying your constants in the precision dictated by the destination type, provided that you will not lose precision in the calculation by doing so (ie, your operands are exactly representable in the precision of the destination type ).</p> |

1,216,211 | 0 | <p>Before you get started, do not use macro names that begin with an underscore - these are reserved for compiler and standard library writers, and must not be used in your own code.</p> <p>Additionally, I would say that the macros you suggest are all ver bad ideas, because they hide from the reader what is going on. The only justification for them seems to be to save you a very small amount of typing. Generally, you should only be using macros when there is no sensible alternative. In this case there is one - simply write the code.</p> |

22,923,884 | 0 | <p>To understand why these kind of operations seem non-trivial in NoSQL implementations, it's good to think about why NoSQL exists (and has become very popular) at all.</p> <p>When you look at an early NoSQL implementation like memcached, the first use case was very simple, but very important: a blazingly fast cache for distributed data, to cache for example web page data. Very quickly stuff like clustering and sharding was added, so not all data has to be available everywhere at once at every single node in the cluster, but can be gathered on demand.</p> <p>NoSQL is very different from relational data storage. Don't overuse it. Consider relational databases as well, as they are sometimes far more suited for what you are trying to accomplish. In everything you design, ask yourself "Does this scale well?".</p> <p>Okay, back to your question. It is in general bad practice to do wildcard searches. You prepare your data in a way that you can retrieve your data in a scalable way.</p> <p>Redis is a very chique solution, allowing you to overcome a lot of NoSQL limitations in an elegant way.</p> <p>If getting "a list of all users" isn't something you have to do very often, or doesn't need to scale well, is always "I really always want <strong>all</strong> users" because it's for a daily scan anyway, use <code>HSCAN</code>. <code>SCAN</code> operations with a proper batch size don't get in the way of other clients, you can just retrieve your records a couple of thousand at a time, and after a few calls you've got everything.</p> <p>You can also store your users in a <code>SET</code>. There's no ordering in a set, so no pagination. It can help to keep your user names unique.</p> <p>If you want to do things like "get me all users that start with the letter 'a'", I'd use a <code>ZSET</code>. I'd wait a week or two for <code>ZRANGEBYLEX</code> which is just about to be released, in the works as we speak. Or use an ORM like Josiah Carlsons's 'rom' package.</p> <p>When you ask yourself "But now I have to do three calls instead of one when storing my data...?!": yup, that's how it works. If you need atomicity, use a Lua script, or MULTI+EXEC pipelining. Lua is generally easier.</p> <p>You can also ask yourself if using a <code>HSET</code> is needed. Do you need to retrieve the individual data members? Each key or member has some overhead. On top of that, <code>HGETALL</code> has a Big-O specification of <code>O(N)</code>, so it doesn't scale well. It might be better to serialize your row as a whole, using JSON or MsgPack, and store it in one <code>HSET</code> member, or just a simple <code>GET</code>/<code>SET</code>. Also read up on <code>SORT</code>.</p> <p>Hope this helps, TW</p> |

3,428,771 | 0 | <blockquote> <p>3: Lastly he asked if it is possible to used Singleton Object with Clusters with explanation and is there any way to have Spring not implement Singleton Design Pattern when we make a call to Bean Factory to get the objects ?</p> </blockquote> <p>The first part of this question is hard to answer without a technological context. If the cluster platform includes the ability to make calls on remote objects as if they were local objects (e.g. as is possible with EJBs using RMI or IIOP under the hood) then yes it can be done. For example, the JVM resident singleton objects could be proxies for a cluster-wide singleton object, that was initially located / wired via JNDI or something. But cluster-wide singletons are a potential bottleneck because each call on one of the singleton proxies results in an (expensive) RPC to a single remote object.</p> <p>The second part of the question is that Spring Bean Factories can be configured with different scopes. The default is for singletons (scoped at the webapp level), but they can also be session or request scoped, or an application can define its own scoping mechanism.</p> |

Line 1331 shows you how the command has to look like.</p> <p>Also note that the returnvalue <code>rv</code> does not tell you whether the command was successfully executed on the TPM. It just tells you whether TBS was able to send the command and recieve the response. You have to decode the <code>pabResult</code> buffer.</p> <p>You should also look at my answer to your <a href="http://stackoverflow.com/questions/24145810/sealing-data-using-tpm-in-windows">other question</a>.</p> |
10,227,882 | 0 | <p>Since <code>friend</code> relationships aren't inherited, you need to declare <code>convertF</code> as a friend of both classes. But you need this only if the function needs access the internals of these classes - are you sure the public interface of the classes doesn't suffice?</p> <p>One further reason to try to avoid such a double friend is that it would create a circular dependency between these classes via the signature of <code>convertF</code>. </p> <p><strong>Update:</strong> This is exactly why you can't declare your friend function the way you show above. For this to work, the compiler would need to know the full definition of <code>iFraction</code> while it is still not finished with the definition of the base class <code>Fraction</code>, which is impossible.</p> <p>Technically it could work the other way around, by forward declaring <code>iFraction</code>. Although I still wouldn't consider it a good solution. Are you sure your class hierarchy is right?</p> |

34,208,877 | 0 | Erlang's FSM code_change function usage <p>I'm learning Erlang and I've learned about hot code loading, but I don't know how the gen_fst behavior's code_change function works. I also can't find any example of it.</p> <p>Should I create an action like so:</p> <pre><code>upgrade() -> gen_fsm:send_event(machine_name, upgrade). </code></pre> <p>And have a handler in the states like so:</p> <pre><code>some_state(upgrade, State) -> code:purge(?MODULE), compile:file(?MODULE), code:load_file(?MODULE), {next_state, some_state, State, 1000}. </code></pre> <p>I've tried this, but the <code>code_change/4</code> function doesn't execute.
