32,637,640 | 0 | <p>Your procedure takes two parameters. You are calling it without any parameters. Oracle thus looks for a procedure named <code>spfirst</code> that takes no parameters, finds no such procedure, and throws an error.</p> <p>Something like</p> <pre><code>DECLARE l_location nilesh.location%type; l_salary nilesh.monthly_salary%type; BEGIN spfirst( l_location, l_salary ); END; </code></pre> <p>should work. Of course, you'd generally want to do something with the variables that are returned. If you've enabled <code>dbms_output</code>, you could print them out</p> <pre><code>DECLARE l_location nilesh.location%type; l_salary nilesh.monthly_salary%type; BEGIN spfirst( l_location, l_salary ); dbms_output.put_line( 'Location = ' || l_location ); dbms_output.put_line( 'Salary = ' || l_salary ); END; </code></pre> <p>Be aware that your procedure will throw an error unless the <code>nilesh</code> table has exactly one row. It seems likely that you either want the procedure to take an additional parameter that is the key to the table so that the <code>select into</code> always returns a single row or that you want a function that returns a <code>sys_refcursor</code> rather than a procedure that has multiple <code>out</code> parameters.</p> |
40,454,375 | 0 | <p>No - it's not a prerequisite, even if you have a client app that consumes them - but imho it's a good idea.</p> <p>Microservices architecture is really nothing new as far as concept. Break up your monolithic app into many components that can iterate quickly at their own pace of development. Cloud native tooling and best practices have brought on this new notion of "microservices" with technology like containers and best practices like code as config.</p> <p>For client consumption across a broad spectrum of client capabilities, microservices are more easily and practically managed with a gateway because the gateway is a piece of infrastructure that acts as a control point for QoS concerns such as security, throttling, caching, payload pagination, lightweight transformation, tracebacks through header injection, etc.</p> <p>It's not necessary, but practically speaking if you have one already baked into your microservices development process as part of a cloud ready infrastructure - you address these things during development consideration and not in "big bang" fashion after the fact - a huge burden in the past for devop/ops folks to get their head around. It's such a burden, that that's why we've started our own solution that marries microservices development integration with management under ones cloud native platform and have a market for it</p> |

1,917,084 | 0 | <p>There's a lot here already, so maybe this is just a minor addition but here's what I find to be the biggest differences.</p> <p>Library:</p> <ul> <li>I put this first, because this in my opinion this is the biggest difference in practice. The C standard library is very(!) sparse. It offers a bare minimum of services. For everything else you have to roll your own or find a library to use (and many people do). You have file I/O and some very basic string functions and math. For everything else you have to roll your own or find a library to use. I find I miss extended containers (especially maps) heavily when moving from C++ to C, but there are a lot of other ones.</li> </ul> <p>Idioms:</p> <ul> <li>Both languages have manual memory (resource) management, but C++ gives you some tools to hide the need. In C you will find yourself tracking resources by hand much more often, and you have to get used to that. Particular examples are arrays and strings (C++ <code>vector</code> and <code>string</code> save you a lot of work), smart pointers (you can't really do "smart pointers" as such in C. You <em>can</em> do reference counting, but you have to up and down the reference counts yourself, which is very error prone -- the reason smart pointers were added to C++ in the first place), and the lack of RAII generally which you will notice everywhere if you are used to the modern style of C++ programming. <ul> <li>You have to be explicit about construction and destruction. You can argue about the merits of flaws of this, but there's a lot more explicit code as a result.</li> </ul></li> <li>Error handling. C++ exceptions can be tricky to get right so not everyone uses them, but if you do use them you will find you have to pay a lot of attention to how you do error notification. Needing to check for return values on all important calls (some would argue <em>all</em> calls) takes a lot of discipline and a lot of C code out there doesn't do it.</li> <li>Strings (and arrays in general) don't carry their sizes around. You have to pass a lot of extra parameters in C to deal with this.</li> <li>Without namespaces you have to manage your global namespace carefully. <ul> <li>There's no explicit tying of functions to types as there is with <code>class</code> in C++. You have to maintain a convention of prefixing everything you want associated with a type.</li> </ul></li> <li>You will see a lot more macros. Macros are used in C in many places where C++ has language features to do the same, especially symbolic constants (C has <code>enum</code> but lots of older code uses <code>#define</code> instead), and for generics (where C++ uses templates).</li> </ul> <p>Advice:</p> <ul> <li>Consider finding an extended library for general use. Take a look at <a href="http://library.gnome.org/devel/glib/stable/" rel="nofollow noreferrer">GLib</a> or <a href="http://apr.apache.org/" rel="nofollow noreferrer">APR</a>. <ul> <li>Even if you don't want a full library consider finding a map / dictionary / hashtable for general use. Also consider bundling up a bare bones "string" type that contains a size.</li> </ul></li> <li>Get used to putting module or "class" prefixes on all public names. This is a little tedious but it will save you a lot of headaches.</li> <li><p>Make heavy use of forward declaration to make types opaque. Where in C++ you might have private data in a header and rely on <code>private</code> is preventing access, in C you want to push implementation details into the source files as much as possible. (You actually want to do this in C++ too in my opinion, but C makes it easier, so more people do it.)</p> <p>C++ reveals the implementation in the header, even though it technically hides it from access outside the class.</p> <pre><code>// C.hh class C { public: void method1(); int method2(); private: int value1; char * value2; }; </code></pre> <p>C pushes the 'class' definition into the source file. The header is all forward declarations.</p> <pre><code>// C.h typedef struct C C; // forward declaration void c_method1(C *); int c_method2(C *); // C.c struct C { int value1; char * value2; }; </code></pre></li> </ul> |

36,608,615 | 0 | <p>In case of conflict you should select the higher number of the two. But whatever you choose it has no impact on actual migrations. </p> <p>If you choose the lower number then next time you run <code>rake db:migrate</code> it will change this number (to the higher one) and you will have a change in your <code>schema.rb</code> and no migration. It's not a problem - only your commit will be a bit strange.</p> <p>Rails rake task runs all migrations that it finds and that don't have a value in <code>schema_migrations</code> table. And then it takes the highest migration timestamp and puts this timestamp into the <code>schema.rb</code>. The whole migration idea is not based on some "most recent timestamp" (schema version) but it's based on the content of <code>schema_migrations</code> table that contains all migration timestamps that it has already run. So through this table it guarantees that no migration is skipped.</p> |

In one word, each function along the pipeline call its next function in a nesting way.</p> <p>For example, for a pipeline <code>A</code>-><code>B</code>-><code>C</code>.</p> <p>At the top level, some code is written like this:</p> <p><code>q.enqueue(A, the_doc)</code></p> <p>where q is the <code>Queue</code> instance and in function <code>A</code> there are code like:</p> <p><code>q.enqueue(B, the_doc)</code></p> <p>And in <code>B</code>, there are something like this:</p> <p><code>q.enqueue(C, the_doc)</code></p> <p>Is there any other way more elegant than this? For example some code in <strong>ONE</strong> function:</p> <p><code>q.enqueue(A, the_doc) q.enqueue(B, the_doc, after = A) q.enqueue(C, the_doc, after= B) </code></p> <p><a href="http://python-rq.org/docs/" rel="nofollow">depends_on</a> parameter is the closest one to my requirement, however, running something like:</p> <p><code> A_job = q.enqueue(A, the_doc) q.enqueue(B, depends_on=A_job )</code></p> <p>won't work. As <code>q.enqueue(B, depends_on=A_job )</code> is executed immediately after <code>A_job = q.enqueue(A, the_doc)</code> is executed. By the time B is enqueued, the result from A might not be ready as it takes time to process.</p> <p>PS:</p> <p>If Python RQ is not really good at this, what else tool in Python can I use to achieve the same purpose:</p> <ol> <li>round-robin parallelization</li> <li>pipeline processing support</li> </ol> |

How would I go about finding the REAL coordinates of a point relative to the newly rotated object?</p> <p>Example: <img src="https://i.stack.imgur.com/LfEtJ.png" alt="enter image description here"></p> <p>How would I, for instance, find the forward-most corner of the cube given its Forward, Right, and Up vectors (as well as its coordinates, obviously) assuming that the colored axis is the 'real' axis.</p> <p>The best I could come up with is:</p> <pre><code>x=cube.x+pointToFind.x*(forward.x+right.x+up.x) y=cube.y+pointToFind.y*(forward.y+right.y+up.y) z=cube.z+pointToFind.z*(forward.z+right.z+up.z) </code></pre> <p>This worked sometimes, but failed when one of the coordinates for the point was 0 for obvious reasons.</p> <p>In short, I don't know what do to, or really how to accurately describe what I'm trying to do... This is less of a programming questions and more of a general math question.</p> |

39,919,539 | 0 | <p>You can not remove keys from a dictionary in a signed document, and expect the signatures to remain valid. You can only remove the last signature that was added. If a document was signed by multiple people, and you want to remove the first signature, all subsequent signatures will be broken.</p> <p>This image explains why:</p> <p><a href="https://i.stack.imgur.com/7f0D7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7f0D7.png" alt="enter image description here"></a></p> <p>This image shows that every new digital signature keeps the original bytes intact. With every new signature new bytes are added. Rev1 represents the bytes of a document that has 1 digital signature. Rev2 represents the bytes of a document that has 2 digital signatures. The second digital signatures signs Rev1 completely. If you'd remove the first signature, the second signature would become invalid.</p> <p>A digital signature is a special type of form field. With iText, you can get the names of the signature form fields of a PDF like this:</p> <pre><code>PdfReader reader = new PdfReader(path); AcroFields fields = reader.getAcroFields(); ArrayList<String> names = fields.getSignatureNames(); </code></pre> <p>You can only remove the signature that covers the whole document, for instance, if we have <code>"sig1"</code>, <code>"sig2"</code>, and <code>"sig3"</code> (added in that order), only <code>fields.signatureCoversWholeDocument("sig3")</code> will return true.</p> <p>You can get the total number of revisions like this: <code>fields.getTotalRevisions()</code> and a specific revision like this: <code>fields.getRevision("sig1")</code> (provided that there's a signature field named <code>"sig1"</code>).</p> <p>Suppose that the image represents your document, and you have to remove 1 signature, then you can only remove the third signature by removing all the bytes that were added in revision 3 (Rev3). With iText, that means going back to revision 2 (Rev2). That revision was signed using the signature field <code>sig2</code>. You can extract this revision like this:</p> <pre><code>FileOutputStream os = new FileOutputStream("revision2.pdf"); byte bb[] = new byte[1028]; InputStream ip = fields.extractRevision("sig2"); int n = 0; while ((n = ip.read(bb)) > 0) os.write(bb, 0, n); os.close(); ip.close(); </code></pre> <p>The file <code>revision2.pdf</code> will be the file signed by <code>"sig1"</code> and <code>"sig2"</code> without the bytes that were added when creating <code>"sig3"</code>.</p> |

18,219,240 | 0 | <p>You need to rethink your question. You don't want the 'string' to be case insensitive, but much rather your comparison to realize, that HKCU is the same as Hkcu or hKcU.</p> <p>For this end, there's a number of options, one of which is the already mentioned function <code>stricmp</code>. Prototype is:</p> <pre><code>#include <string.h> int stricmp(const char *string1, const char *string2); </code></pre> <p>Meaning, you'd use it like:</p> <pre><code>if(stricmp(argv[2], "HKCU") == 0) { } </code></pre> <p>Another option is the <code>strcasecmp</code> function which operates similarly.</p> <p>Hope this helps.</p> |

32,612,324 | 0 | How to subset data for a specific column with ddply? <p>I would like to know if there is a simple way to achieve what I describe below using <code>ddply</code>. My data frame describes an experiment with two conditions. Participants had to select between options <em>A</em> and <em>B</em>, and we recorded how long they took to decide, and whether their responses were accurate or not. </p> <p>I use <code>ddply</code> to create averages by condition. The column <code>nAccurate</code> summarizes the number of accurate responses in each condition. I also want to know how much time they took to decide and express it in the column <code>RT</code>. However, I want to calculate average response times <strong>only when participants got the response right</strong> (i.e. <code>Accuracy==1</code>). Currently, the code below can only calculate average reaction times for all responses (accurate and inaccurate ones). Is there a simple way to modify it to get average response times computed only in accurate trials?</p> <p>See sample code below and thanks!</p> <pre><code>library(plyr) # Create sample data frame. Condition = c(rep(1,6), rep(2,6)) #two conditions Response = c("A","A","A","A","B","A","B","B","B","B","A","A") #whether option "A" or "B" was selected Accuracy = rep(c(1,1,0),4) #whether the response was accurate or not RT = c(110,133,121,122,145,166,178,433,300,340,250,674) #response times df = data.frame(Condition,Response, Accuracy,RT) head(df) Condition Response Accuracy RT 1 1 A 1 110 2 1 A 1 133 3 1 A 0 121 4 1 A 1 122 5 1 B 1 145 6 1 A 0 166 # Calculate averages. avg <- ddply(df, .(Condition), summarise, N = length(Response), nAccurate = sum(Accuracy), RT = mean(RT)) # The problem: response times are calculated over all trials.
