22,360,469 | 0 | <p>I would go the one field approach. You could have three columns, <code>Name</code>, <code>Surname</code>, and <code>field_values</code>. In the <code>field_values</code> column, store a PHP <a href="http://php.net/serialize" rel="nofollow"><code>serialized</code></a> string of an array representing what would otherwise be your columns. For example, running:</p> <pre><code>array( ['col1'] => 'val', ['col2'] => 'val1', ['col3'] => 'val2', ['col4'] => 'val3' ) </code></pre> <p>through <code>serialize()</code> would give you:</p> <pre><code>a:4:{s:4:"col1";s:3:"val";s:4:"col2";s:4:"val1";s:4:"col3";s:4:"val2";s:4:"col4";s:4:"val3";} </code></pre> <p>and you can take this value and run it back through <code>unserialize()</code> to restore your array and use it however you need to. Loading/saving data within this array is no more difficult than changing values in the array before serializing it and then saving it to the <code>field_values</code> column.</p> <p>With this method you can have as many or few 'columns' as you need with no need for a ton of columns or tables.</p> |

38,008,596 | 0 | <p><strong>You can't <em>change</em> the ID of an entity</strong>. The ID uniquely identifies an entity object. Different ID = different entity object. You can manually edit the value of the annotated <code>@Id</code> column in the database, sure; but for all purposes, that record is now a <em>different</em> entity object, because it has a different ID.<br> For any framework to <em>know</em> that your <code>User</code> is the same <code>User</code> despite having a different ID, there'd have to exist some other internal column that could be used to identify the User. Something like "oh, ok, the <code>openID</code> is different but the <code>socialSecurityNumber</code> is the same, so it's the same <code>User</code>". But then again, your ID would not be the <code>openID</code> field: you'd have to annotate <code>socialSecurityNumber</code> as the actual <code>@Id</code> so the framework knows.</p> <p>And in fact, in your example you're doing this:</p> <pre><code>User user = userRepo.findOne("o3sVZuA4p81wG24ph5Z5lmnrVhlc"); </code></pre> <p>So it seems like you <em>do</em> have a unique ID <code>"o3sVZuA4p81wG24ph5Z5lmnrVhlc"</code>, it's only that you haven't declared it in your <code>User</code>.</p> <p>Just remove the <code>@Id</code> annotation from <code>openId</code> and declare that other field as <code>@Id</code>. That way you'd be able to update the <code>openID</code> of any <code>User</code> and have it reflected in every <code>Gift</code> too.</p> |

1,426,808 | 0 | Can I deploy in SharePoint two Web Parts with the same DLL, but two .webpart files, at the same time <p>Is it possible to have two Web Parts with the same DLL, but two .webpart files, deployed in Sharepoint at the same time?</p> <p><strong>Background</strong> : I am developing an application that will generate a ".cab" file containing a Web Part (ASP.NET 2.0 Web Part). After that, the user should be able to deploy this ".cab" file in a in a SharePoint server.</p> <p>My application already includes the DLL of a Web Part. The "behavior" of this Web Part depends on the properties of the ".webpart" file which will be generated at runtime by my application (its content will change depending on certain user choices) After generating the ".webpart" file, it packages it to a ".cab" file along a Manifest.xml and the DLL.</p> <p>Imagine that the user creates two "cab" files using my application. And he wants to deploy them into SharePoint.</p> <p>To test this, I create this two ".cab" files with my app, and in SharePoint I execute:</p> <pre><code>$> STSADM.EXE -o addwppack <cab filename #1> $> STSADM.EXE -o addwppack <cab filename #2> $> STSADM.EXE -o deletewppack <cab filename #1> </code></pre> <p>After the execution of the third command, the Web Part #2 doesn't have the DLL. When I installed Web Part #2, SharePoint override the DLL file of Web part #1 The problem here is that the DLL of both files is copied to same location. That location is the Assembly name of DLL. That assembly name cannot be changed without recompiling again (I think).</p> <p>Is there anyway to deploy two cab files independently, even if they share the same DLL?</p> |

5,587,652 | 0 | <p>This might be more of a process issue and less of a coding issue.</p> <p>You need to strictly separate the implementation process and the roll-out process during software development. The configuration files containing the passwords must be filled with the real passwords during roll-out, not before. The programmers can work with the password for the developing environment and the roll-out team changes those passwords once the application is complete. That way the real passwords are never disclosed to the people coding the application.</p> <p>If you cannot ensure that programmers do not get access to the live system, you need to encrypt the configuration files. The best way to do this depends on the programming language. I am currently working on a Java application that encrypts the .properties files with the appropriate functions from the <a href="http://www.owasp.org/index.php/Category%3aOWASP_Enterprise_Security_API" rel="nofollow">ESAPI project</a> and I can recommend that. If you are using other languages, you have to find equivalent mechanisms.</p> <p>Any time you want to change passwords, an administrator generates a new file and encrypts it, before copying the file to the server.</p> <p>In case you want maximum security and do not want to store the key to decrypt the configuration on your system, an administrator can supply it whenever the system reboots. But this might take things too far, depending on your needs.</p> |

Look at this excerpt based on your code when I tested in the Immediate window:</p> <pre class="lang-sql prettyprint-override"><code>intYear = 2015 ?

"WHERE [Market Segment]= 'CMS Part D (CY " & (intYear) & ")'" WHERE [Market Segment]= 'CMS Part D (CY 2015)' </code></pre> <p>I encourage you to follow KevenDenen's advice to add <code>Debug.Print strCount2</code> to the code after it has finished building the <code>strCount2</code> string. Then you can run the code and view the text of the completed statement in the Immediate window. (You can use <kbd>Ctrl</kbd>+<kbd>g</kbd> to go to the Immediate window.) It helps tremendously to examine the actual statement your code is asking Access to execute.</p> |

10,625,584 | 1 | Embedding python in multithreaded C application <p>I'm embedding the python interpreter in a multithreaded C application and I'm a little confused as to what APIs I should use to ensure thread safety.</p> <p>From what I gathered, when embedding python it is up to the embedder to take care of the GIL lock before calling any other Python C API call. This is done with these functions:</p> <pre><code>gstate = PyGILState_Ensure(); // do some python api calls, run python scripts PyGILState_Release(gstate); </code></pre> <p>But this alone doesn't seem to be enough. I still got random crashes since it doesn't seem to provide mutual exclusion for the Python APIs.</p> <p>After reading some more docs I also added: </p> <pre><code>PyEval_InitThreads(); </code></pre> <p>right after the call to <code>Py_IsInitialized()</code> but that's where the confusing part comes. The docs state that this function:</p> <blockquote> <p>Initialize and acquire the global interpreter lock</p> </blockquote> <p>This suggests that when this function returns, the GIL is supposed to be locked and should be unlocked somehow. but in practice this doesn't seem to be required. With this line in place my multithreaded worked perfectly and mutual exclusion was maintained by the <code>PyGILState_Ensure/Release</code> functions.<br> When I tried adding <code>PyEval_ReleaseLock()</code> after <code>PyEval_ReleaseLock()</code> the app dead-locked pretty quickly in a subsequent call to <code>PyImport_ExecCodeModule()</code>.</p> <p>So what am I missing here? </p> |
39,252,109 | 0 | <h2>Solution #1: Star unpacking for one-line initialization</h2> <p>Star-unpacking will work, but only if all the fields in your structure are integer types. In Python 2.x, <code>c_char</code> cannot be initialized from an <code>int</code> (it works fine in 3.5). If you change the type of <code>state</code> to <code>c_byte</code>, then you can just do:</p> <pre><code>mystr = MyStruct(*myarr) </code></pre> <p>This doesn't actually benefit from any <code>array</code> specific magic (the values are briefly converted to Python <code>int</code>s in the unpacking step, so you're not reducing peak memory usage), so you'd only bother with an <code>array</code> if initializing said <code>array</code> was easier than directly reading into the structure for whatever reason.</p> <p>If you go the star unpacking route, reading <code>.state</code> will now get you <code>int</code> values instead of len 1 <code>str</code> values. If you want to initialize with <code>int</code>, but read as one character <code>str</code>, you can use a protected name wrapped in a <code>property</code>:</p> <pre><code>class MyStruct(Structure): _fields_ = [... ("_state", c_byte), # "Protected" name int-like; constructor expects int ...] @property def state(self): return chr(self._state) @state.setter def state(self, x): if isinstance(x, basestring): x = ord(x) self._state = x </code></pre> <p>A similar technique could be used without <code>property</code>s by defining your own <code>__init__</code> that converted the <code>state</code> argument passed:</p> <pre><code>class MyStruct(Structure): _fields_ = [("init", c_uint), ("state", c_char), ...] def __init__(self, init=0, state=b'\0', *args, **kwargs): if not isinstance(state, basestring): state = chr(state) super(MyStruct, self).__init__(init, state, *args, **kwargs) </code></pre> <h2>Solution #2: Direct <code>memcpy</code>-like solutions to reduce temporaries</h2> <p>You can use some <code>array</code> specific magic to avoid the temporary Python level <code>int</code>s though (and avoid the need to change <code>state</code> to <code>c_byte</code>) without real file objects using a fake (in-memory) file-like object:</p> <pre><code>import io mystr = MyStruct() # Default initialize # Use BytesIO to gain the ability to write the raw bytes to the struct # because BytesIO's readinto isn't finicky about exact buffer formats io.BytesIO(myarr.tostring()).readinto(mystr) # In Python 3, where array implements the buffer protocol, you can simplify to: io.BytesIO(myarr).readinto(mystr) # This still performs two memcpys (one occurs internally in BytesIO), but # it's faster by avoiding a Python level method call </code></pre> <p>This only works because your non-<code>c_int</code> width attributes are followed by <code>c_int</code> width attributes (so they're padded out to four bytes anyway); if you had two <code>c_ubyte</code>/<code>c_char</code>/etc. types back to back, then you'd have problems (because one value of the <code>array</code> would initialize two fields in the struct, which does not appear to be what you want).</p> <p>If you were using Python 3, you could benefit from <code>array</code> specific magic to avoid the cost of both unpacking and the two step <code>memcpy</code> of the <code>BytesIO</code> technique (from <code>array</code> -> <code>bytes</code> -> struct). It works in Py3 because Py3's <code>array</code> type supports the buffer protocol (it didn't in Py2), and because Py3's <code>memoryview</code> features a <code>cast</code> method that lets you change the format of the <code>memoryview</code> to make it directly compatible with <code>array</code>:</p> <pre><code>mystr = MyStruct() # Default initialize # Make a view on mystr's underlying memory that behaves like a C array of # unsigned ints in native format (matching array's type code) # then perform a "memcpy" like operation using empty slice assignment # to avoid creating any Python level values. memoryview(mystr).cast('B').cast('I')[:] = myarr </code></pre> <p>Like the <code>BytesIO</code> solution, this only works because your fields all happen to pad to four bytes in size</p> <h2>Performance</h2> <p>Performance-wise, star unpacking wins for small numbers of fields, but for large numbers of fields (your case has a couple dozen), direct <code>memcpy</code> based approaches win out; in tests for a 23 field class, the <code>BytesIO</code> solution won over star unpacking on my Python 2.7 install by a factor of 2.5x (star unpacking was 2.5 microseconds, <code>BytesIO</code> was 1 microsecond).</p> <p>The <code>memoryview</code> solution scales similarly to the <code>BytesIO</code> solution, though as of 3.5, it's slightly slower than the <code>BytesIO</code> approach (likely a result of the need to construct several temporary <code>memoryview</code>s to perform the necessary casting operations and/or the <code>memoryview</code> slice assignment code being general purpose for many possible formats, so it's not simple <code>memcpy</code> in implementation). <code>memoryview</code> might scale better for much larger copies (if the losses are due to the fixed <code>cast</code> overhead), but it's rare that you'd have a struct large enough to matter; it would only be in more general purpose copying scenarios (to and from <code>ctypes</code> arrays or the like) that <code>memoryview</code> would potentially win.</p> |

23,700,348 | 0 | <p>I've created an overly complex solution that allows you to create a helper function to do an inline type of rang value finder. The ranger function takes the cut points you want to split on and then returns a function that will choose the value of the parameter based on which interval it falls. It primarily uses <code>findInterval</code> but unfortunately you inequalities don't exactly line up with how <code>findInterval</code> likes to do them so I had to do some fiddling.</p> <pre><code>#meta-helper function ranger<-function(rng) { function(x, ...) { dots<-list(...) stopifnot(ncol(dots)==length(rng)+1) m<-findInterval(x, rng)+1 ex<-match(x, rng); if (any(!is.na(ex))) { m[which(ex>1)]<-ex[which(ex>1)] } out<-rep(NA, length(x)) for(i in seq_along(dots)) { out[m==i]<-rep(dots[[i]], length.out=length(x))[m==i] } out; } } #helper function abc<-ranger(c(600,4000)) #implementation 1 x<-c(100,2000,5000) a<-abc(x, 0.01, 0.1, 0.12)*x + abc(x, 0, 118, -162); a; #implementation 2 a<-abc(x, x * 0.01, 118 + (x*0.1), 318 + ((x-4000)*0.12)); a; </code></pre> <p>So while it may not be the best choice in this case, i might be useful if you have a bunch of different ranges or something like that.</p> |

11,961,081 | 0 | <p>You'll need to use Tomcat 7 (or any other container that supports Servlet 3.0 onwards) to use that style of programming.

Note that consequently the <code>contain</code> config has to be changed too!</p> <pre><code>$this->Profile->bindModel(array( 'belongsTo' => array( 'Region' => array( 'foreignKey' => false, 'conditions' => array('Region.id = Store.region_id') ), ) )); $this->Paginator->settings = array( 'conditions' => array('Profile.job_title_id' => '1'), 'contain' => array('Store', 'Region') ); </code></pre> <p>That should generate a proper query that includes the <code>stores</code> as well as the <code>regions</code> table, making it possible to sort on <code>Region.name</code>. Note that the resulting array will be a little different, <code>Region</code> will not be nested in <code>Store</code>, everything will be placed in the same level, ie:</p> <pre><code>Array ( [Profile] => Array ( .... ) [Store] => Array ( .... ) [Region] => Array ( .... ) ) </code></pre> <p>Either you modify your view code accordingly, or you transform the retrieved data before passing it to the view. A third option would be to include a nested <code>Region</code> in the <code>contain</code> config, however that would result in additional queries that are totally unnecessary as the data was already fetched with the main query, so I wouldn't recommend that.</p> |

If it doesn't then you actually do get threads, but that's using the pattern for no good reason. The <em>await expression</em>, what you write on the right side of the await keyword causes threads to run.</p> <p>But that thread is often not observable, it may be a device driver thread. Which reports that it is done with a I/O completion port. Pretty common, I/O is always a good reason to use await. If not already forced on you by WinRT, the real reason that async/await got added.</p> <p>A note about "having a synchronization context". You have one on a thread if the SynchronizationContext.Current property is not null. This is almost only ever the case on the main thread of a gui app. Also the only place where you normally ever worry about having delays not freeze your user interface.</p> |

Even if they don't, you're guaranteeing yourself the headache of maintaining them in parallel whenever a change occurs. And change will occur. Don't repeat yourself is important if you want flexible and maintainable software.</p></li> <li><p><strong>Once and Only Once</strong></p> <p>Each and every declaration of behavior should occur once, and only once. This is one of the main goals, if not the main goal, when refactoring code. The design goal is to eliminate duplicated declarations of behavior, typically by merging them or replacing multiple similar implementations with a unifying abstraction.</p></li> <li><p><strong>Single Point of Truth</strong></p> <p>Repetition leads to inconsistency and code that is subtly broken, because you changed only some repetitions when you needed to change all of them.
