6,047,463 | 0 | <p>Because the triple design doesn't prevent you from using a closure, while the alternative approach prevents you from <em>not</em> using closures. Sometimes the external-state design is the simpler approach.</p> <p>For instance, say that you're using a <code>for</code> loop to iterate which pages to display in the response to a RESTful query. With external-state-based loops, you can write a function that iterates pages based on a table representing the state-representational parameters of the query (which you construct from the URL once and reuse for several other functions). With triples, you can iterate with just those values without being forced to wrap it (and every other function like it) in a closure constructor.</p> |

20,237,644 | 0 | <p>Creating snapshots in VHD works by putting an overlay over the existing VHD image, so that any change get written into the overlay file instead of overwriting existing data. For reading the top-most data is returned: either the data from the overlay if that sector/cluster was already over-written, or from the original VHD file if it was not-yet over-written.</p> <p>The vhd-util command creates such an overlay-VHD-file, which uses the existing VHD image as its so-called "backing-file". It is important to remember, that the backing-file must never be changed while snapshots still using this backing-file exist. Otherwise the data would change in all those snapshots as well (unless the data was overwritten there already.)</p> <p>The process of using backing files can be repeated multiple times, which leads to a chain of VHD files. Only the top-most file should ever be written to, all other files should be handled as immutable.</p> <p>Reverting back to a snapshot is as easy as deleting the current top-most overlay file and creating a new empty overlay file again, which again expose the data from the backing file containing the snapshot. This is done by using the same command again as above mentioned. This preserves your current snapshot and allows you to repeat that process multiple times. (renaming the file would be more like "revert back to <strong>and</strong> delete last snapshot".)</p> <p><strong>Warning:</strong> before re-creating the snapshot file, make sure that no other snapshots exists, which uses this (intermediate) VHD file as its backing file. Otherwise you would not only loose this snapshot, but all other snapshots depending on this one.</p> |

26,172,001 | 0 | <p>Many answers here discuss the potential overflow issues of using <code>scanf("%s", buf)</code>, but the latest POSIX specification more-or-less resolves this issue by providing an <code>m</code> assignment-allocation character that can be used in format specifiers for <code>c</code>, <code>s</code>, and <code>[</code> formats.

23,315,569 | 0 | <p>First, you need to know <em>What is a string in C?</em>. A string is an array of non-zero bytes (<code>char</code>), usually printable characters, which terminate in a null (zero, represented by the character <code>'\0'</code>).</p> <p>Then, you need to know how a <code>for</code> loop works:</p> <pre><code>for ( initial condition ; test condition ; loop expression ) { // some code } // Code after the loop </code></pre> <p>The <code>for</code> loop will:</p> <ol> <li>Execute <em>initial condition</em></li> <li>Execute <em>test condition</em> and, if it's TRUE (non-zero) will execute <em>some code</em>. Otherwise, if it's FALSE (zero) it will EXIT the loop and go to the <em>Code after the loop</em>.</li> <li>Execute <em>loop expression</em></li> <li>Go to 2</li> </ol> <p>With the basics out of the way, let's look at the function given by the teacher:</p> <pre><code>int length(char *word) { int i; for (i = 0; word[i] != '\0'; i++) { { } } return i; } </code></pre> <p>The meat of the function is the <code>for</code> loop: It then goes through the <code>for</code> loop steps:</p> <ol> <li>Initially, <code>i</code> is set to <code>0</code>. <code>i</code> represents the index into the string (array of <code>char</code>).</li> <li>Check if <code>word[i] != '\0'</code> (in other words, if this is TRUE, then it's not the end of the string). There's no code inside the loop to execute, so we go right to step 3.</li> <li>The <em>loop expression</em> is executed, which is incrementing <code>i</code>, the string (<code>char</code> array) index, meaning we are now pointing to the next character in the string.</li> </ol> <p>If your word is, "cat", then the array is <code>{ 'c', 'a', 't', '\0' }</code>. So the loop steps will do this:</p> <ol> <li>Set <code>i</code> to <code>0</code>.</li> <li>Check <code>word[0] != '\0'</code>, which checks <code>'c' != '\0'</code>. This is TRUE because <code>'c'</code> is NOT equal to <code>'\0'</code>.</li> <li>Take <code>i++</code> (increment <code>i</code>), so now <code>i</code> is <code>1</code>.</li> <li>Check <code>word[1] != '\0'</code>, which checks <code>'a' != '\0'</code>. This is TRUE because <code>'a'</code> is NOT equal to <code>'\0'</code>.</li> <li>Take <code>i++</code> (increment <code>i</code>), so now <code>i</code> is <code>2</code>.</li> <li>Check <code>word[2] != '\0'</code>, which checks <code>'t' != '\0'</code>. This is TRUE because <code>'t'</code> is NOT equal to <code>'\0'</code>.</li> <li>Take <code>i++</code> (increment <code>i</code>), so now <code>i</code> is <code>3</code>.</li> <li>Check <code>word[3] != '\0'</code>, which checks <code>'\0' != '\0'</code>. This is FALSE because <code>'\0'</code> is equal to <code>'\0'</code>.</li> <li>The loop ends now because the <em>test condition</em> has become FALSE.</li> </ol> <p>What's the value of <code>i</code> at the end of the loop? It's <code>3</code>, which is the length of the string because we kept stepping through the string, one character at a time, incrementing <code>i</code> from <code>0</code> until we hit the spot after the last character of the string, which is <code>'\0'</code>.</p> <p>The function then returns <code>i</code>, the length of the string.</p> <p>HTH</p> |

31,314,457 | 0 | GL_UNPACK_SWAP_BYTES was not declared in this scope & others <p>So i'm trying to use the <code>glPixelStorei</code> methods from OpenGL ES 2.0 in an NDK plugin i'm writing. After some fiddling with the includes, I can get it doing most things i want. However, there is an ongoing issue with getting the defined macros like in the title to work. Currently, eclipse is producing errors like the title for each of the macros in the first arguments of each call below: </p> <pre><code>glPixelStorei( GL_UNPACK_SWAP_BYTES, GL_FALSE ); glPixelStorei( GL_UNPACK_LSB_FIRST, GL_TRUE ); glPixelStorei( GL_UNPACK_ROW_LENGTH, 0 ); glPixelStorei( GL_UNPACK_SKIP_PIXELS, 0); glPixelStorei( GL_UNPACK_SKIP_ROWS, 0); </code></pre> <p>However, it shows <code>glPixelStorei( GL_UNPACK_ALIGNMENT, 0);</code> as error-free and even tells me <code>GL_UNPACK_ALIGNMENT</code> has a value of (<code>0x0CF5</code>). It will build fine without the above lines, but they provide some necessary functionality, so fixing it is the priority.</p> <p>I have included: <code>#include <GLES2/gl2.h></code> and <code>#include <EGL/egl.h></code></p> <p>Am I missing an include for macro definitions or is this an issue with OpenGL ES? I noticed after looking at the header files, there are no definitions for the problem macros.</p> <p>I wasn't sure how best to word this issue so i do apologize if this has been asked before, but i was not able to find any questions on the topic.</p> |

When I compile the library, no compilation error is shown, but when I try to compile the application, the linker error LNK2019 is thrown, mentioning a function which is not present in the library.</p> <p>This can mean two things : <li> either the library is not found <li> either the library is found but the mentioned function is not present.</p> <p>I have already tried to recompile the application after having moved the library, and then he complains that the library is not found, so surely he finds the library but not the function inside.</p> <p>Further in the "Error List" window, next to the linker error message, I see the following information in the "File" column: <code>library.lib(object_file.obj)</code>, which indicates that he knows where he should look for that function (the mentioned function is not present in "object_file.c").</p> <p>When I include a file, containing the definition of that function, and I re-compile the library, I receive the following warning message <code>warning LNK4006: "int function(arguments) already defined in other_source_file.obj; second definition ignored</code>, although in "other_source_file.c" that function is not there.</p> <p>So I'm wondering how this is possible: <li> A function is missing, but when I add it, it seems to be present two times. <li> How does the compiler/linker know where he should be looking for that particular function?</p> <p>You're right, people, without any source code excerpt it's very difficult to handle this question. The function I have issues with, is the function "EXT_snprintf", which is referred upon by the function "snprintf" as you can see here:</p> <pre><code>#define snprintf _EXT_snprintf_f extern int snprintf(char* str, size_t size, const char* format, ...); </code></pre> <p>I've found this piece of code in a header file, belonging to the library. I don't find any implementation of <code>_EXT_snprintf_f</code> anywhere.</p> <p>As for the language, I have found the "/TP" flag in both compilation settings, mentioning that the compiler needs to treat the library and the application as C++ sources. (I've removed the "C" tag from the question)</p> <p>Does anybody have an idea?<br/> Thanks</p> |

Tracking branches are prefixed with the remote name (<code>origin</code> in this case). If you perform <code>git checkout gh-pages</code> and no <code>gh-pages</code> branch exists, Git performs <code>git branch --track gh-pages origin/gh-pages</code> before performing the checkout, which creates the <code>gh-pages</code> branch with upstream set to <code>origin/gh-pages</code>.</p> <p>This was probably the source of the errors your Git reported. You fetched just <code>origin/gh-pages</code> and tried to push non-existent <code>gh-pages</code> branch.

6,047,724 | 0 | PDO fetchAll array to one dimensional <p>this may be a simple question but am struggling to understand how to solve it. I have a form which allows the user to select either "custom" or "all" staff" to assign to a job.</p> <p>If custom is selected the user selects staff by clicking each checkbox, I then insert these into a jobs table. This produces the array below (3, 1, 10 are the staff IDs)</p> <pre><code>Array ( [0] => 3 [1] => 1 [2] => 10 ) </code></pre> <p>If "all staff" is selected, I first query a select statement to get all the staff ID's from the staff table, and then insert these into the job table the same as above. However this produces the array :</p> <pre><code>Array ( [0] => Array ( [staffID] => 1 [0] => 1 ) [1] => Array ( [staffID] => 23 [0] => 23 ) [2] => Array ( [staffID] => 26 [0] => 26 ) [3] => Array ( [staffID] => 29 [0] => 29 ) ) </code></pre> <p>How can I convert the array above to the first array shown? </p> <p>I'm using the code below to query the database to get all the staff ID's and then inserting them.</p> <pre><code> $select = $db->prepare("SELECT staffID FROM staff"); if($select->execute()) { $staff = $select->fetchAll(); } for($i = 0; $i<count($staff); $i++) { $staffStmt = $db->prepare("INSERT INTO staffJobs (jobID, userID) VALUES (:jobID, :staffID)"); $staffStmt->bindParam(':jobID', $jobID, PDO::PARAM_INT); $staffStmt->bindParam(':staffID', $staff[$i], PDO::PARAM_INT); $staffStmt->execute(); } </code></pre> <p>The first array inserts fine, however the last array inserts zeros for the staffID.</p> <p>Any suggestions?</p> <p>Thanks =).</p> |
34,638,005 | 0 | <p>There is no penalty to using VMOVDQU when the address is aligned. The behavior is identical to using VMOVDQA in that case.</p> <p>As for "why" there may not be a single clear answer. It's <em>possible</em> that ICC does this deliberately so that users who later call <code>_do</code> with an unaligned argument will not crash, but it's also possible that it's simply emergent behavior of the compiler. Someone on the Intel compiler team could answer this question, the rest of us can only speculate.</p> |
26,288,949 | 0 | Is it possible to show an element just before entering a long running sync process? <p>This is a very simple use case. Show an element (a loader), run some heavy calculations that eat up the thread and hide the loader when done. I am unable to get the loader to actually show up prior to starting the long running process. It ends up showing and hiding after the long running process. Is adding css classes an async process?</p> <p>See my jsbin here:</p> <p><a href="http://jsbin.com/voreximapewo/12/edit?html,css,js,output" rel="nofollow">http://jsbin.com/voreximapewo/12/edit?html,css,js,output</a></p> |
