15,491,442 | 0 | <p>First things first, the CoffeeScript compiler already has a <code>join</code> command: </p> <blockquote> <pre><code>-j, --join [FILE] </code></pre> <p>Before compiling, concatenate all scripts together in the order they were passed, and write them into the specified file. Useful for building large projects.</p> </blockquote> <p>Secondly, instead of using <code>$(document).ready(function () { ...} )</code>, you can just pass the function directly to the <code>$()</code> - <code>$(function () { ... });</code></p> <p>For your actual problem, there are a few ways you could do it.</p> <h2>Option 1:</h2> <p>Compile the .coffee files using the <code>-b / --bare</code> option, and then manually concatenate a file containing <code>$(function() {</code> and the start and <code>});</code> at the end (but that's pretty gross).</p> <h2>Options 2:</h2> <p>Use something like <code>exports = window ? this</code> to get the global object, and assign the functionality you wish to run in the jQuery load function to that global object, eg:</p> <pre><code>FooModule = do -> class Foo constructor: (@blah) -> init = -> blah = new Foo('bar') init: init exports = window ? this exports.Foo = FooModule </code></pre> <p>You could then have another file that contains something like the following:</p> <pre><code>$(-> Foo.init() ) </code></pre> <p>Hope one of those options is good?</p> |
7,936,970 | 0 | <p>If you can display at most one set of topicdetails at a time, have one div set to position 0,0 with <code>display</code>=<code>none</code>. Whenever you need it to show, set the location appropriately (get it from the mousover/hover DOM element, or whatever you use to trigger the event that displays it), and load/set the content. On remove, just set the display to none (you can ignore the content since it will be replace by new content next time it appears).</p> |

23,107,989 | 0 | How to Construct the Email To activity in SharePoint 2013 Workflow <p>I am using SharePoint 2013 SP1 and I am having a problem constructing the Email Activity To attribute. </p> <p>Here's where I am at. I have a created a custom workflow and custom association and initiation form using SharePoint 2013.</p> <p>My Assn. form is fine. I pass in the people Editor control (Active Directory group name ie. SharePointApprovers) value to my workflow just fine.</p> <p>Now on my Init form I use the passed in value from people picker and display a list of users and email addresses from the people picker group. The list of users and email addresses are listed in a table with a check box to the left of each row. I am using JQuery, Knockout and MVC web service to retrieve the values from the group.</p> <p>All is well.</p> <p>Now my users pick who they want to send the email to. Let's say they pick two users! This means my variable is like this (<code>[email protected];[email protected]</code>).</p> <blockquote> <p>When the user clicks the submit button, I have <code>JSOM</code> code which starts the workflow and sends in the 2 users email addresses as an argument to the workflow. Note: I tried sending my two emails as a array and failed but if I send it in as a string it works. The variable is called strUsers.</p> </blockquote> <p>Since the argument is a string and Email Activity To attribute requires an array, I use the <code>BuildCollection<String></code> Activity to convert my string strUsers to an array. I think this worked, as when I added a WriteToHistory Activity to <strong>my workflow my result in workflow history</strong> is as follows... <code>"The value is [email protected];[email protected]"</code>.</p> <p>I then configure the email Activity and set to To property to my BuildActivity variable (recipients). As this is an array.</p> <p>When I deploy my Visual Studio 2013 solution, and attach my workflow to a publishing page, I am getting this error after I submit the Init form.</p> <blockquote> <p>An unhandled exception occurred during the execution of workflow instance. System.ArgumentNullException.</p> </blockquote> <p>Does anyone know of an example of how to set up the Email To collection value.</p> <p>PS I have looked at this <a href="http://blogs.msdn.com/b/officeapps/archive/2013/09/18/step-by-step-sending-email-messages-from-a-workflow-in-an-app-for-sharepoint-2013.aspx" rel="nofollow">link</a> but it is only passing in one variable. In my case I have a string of emails. I need to pass in an array to the Email To property.</p> |

This is guaranteed to link to the currently authenticated user account and so will work across devices.</p> <p>3) Use the Realtime Database API to set a value for 'installed_date'. At launch time, simply retrieve this value and use this.</p> <p>I've done the same and it works great. I was able to test this across uninstall / re-installs and the value in the realtime database remains the same. This way your trial period works across multiple user devices.

31,969,526 | 0 | <p>To find the solution, I set up a virtual environment with seven Redis servers running simultaneously. They were set with sequential port numbers, with the default Redis port (6379) instance being the master. I configured two instances to be slaves to Instance_6379, and configured two more slaves each for Instance_6380 and Instance_6381, respectively. I then checked the <code>redis-cli info</code> output of each, taking note of the <code>connected_slaves</code> metric.</p> <p>Here is what I found: Masters will only report those slaves that are DIRECTLY CONNECTED to them. Slaves of slaves will NOT count towards the total number of slaves connected to the master.</p> <p>In the example image referenced in the question, the leftmost Redis server would have only two <code>connected_slaves</code> and each of its children would also show two <code>connected_slaves</code>.</p> <p>I hope this answer will be of use to someone.</p> |
24,169,795 | 1 | How to pass function parameters with parameter names to an external program in R? <p>For example,</p> <pre><code>passpara = function(pa, pb, pc) { # pa is not passed do1(pa) # pb and pc are passed # passed == "--pb pb_value --pc pc_value" # getpass is something I am trying to figure out passed = getpass(pb, pc) system(paste("cmd", passed)) } </code></pre> <p>To be specific, calling <code>passpara</code> like this:</p> <pre><code>passpara(pa="dummy", pb="full-iso", pc="always") </code></pre> <p>should be equivalent to call this command in shell:</p> <pre><code>cmd --pb full-iso --pc always </code></pre> <p>What would the function <code>getpass</code> look like in this case?</p> <p>I also think the <code>system</code> function is inconvenient sometimes, since it receive a string and you have to delimit arguments manually, is there something similar to python's <code>subprocess.call()</code> in R? In python you can do <code>subprocess.call(["cmd", parameter1, parameter2, parameter3])</code>, and it will delimit the args automatically, this is very handy if the args are strings that contain white spaces.</p> |

37,147,998 | 0 | PHP mysql returns null, hard coded SQL query works <p>I'm having an issue in which I'm unable to get my database query within a PHP program to work. The query works fine within the program if it is hard coded, but it fails otherwise and passes back no results. I have echo'd the two results and am given a different string length, but the string I am given is identical (strings gotten via var_dump). I'm at my wit's end; I'm not really sure what is the issue with the query. I have tried several different fixes which I found for similar problems, but none of them have worked. I trim the posted input and also have the variable double quoted as opposed to single quoted so that the reference executes. I really just have no clue what's wrong. Here is the code that's relevant to this project: AJAX call to php class:</p> <pre><code>chlorinator = ($('#chlorinator').val()).concat(' GS').trim(); $.ajax( { type: "POST", url: "gravity.php", data: "chlorinator="+chlorinator, cache: false, beforeSend: function () { $('#results').html('<img src="loader.gif" alt="" width="24" height="24">'); }, success: function(html) { $("#results").html( html ); }}); </code></pre> <p>And here is the relevant php code:</p> <pre><code><?php include 'connection.php'; $chlorinator = trim( mysqli_real_escape_string ($dbhandle,$_POST["chlorinator"])); $query = 'SELECT chlorinators.model_name, equipment.name, equipment.cutsheet_url, chlorinators.pump_specific, equipment.file_name FROM chlorinators INNER JOIN chlorinator_equipment ON chlorinators.chlorinator_index = chlorinator_equipment.chlorinator_index INNER JOIN equipment ON chlorinator_equipment.equipment_index = equipment.equipment_index WHERE chlorinators.model_name= "' . $chlorinator . '"'; echo "The value of the combined string is:<br> "; var_dump($query); echo '<br><br>'; echo "The value of the hard-coded string is:<br> "; $query = 'SELECT chlorinators.model_name, equipment.name, equipment.cutsheet_url, chlorinators.pump_specific, equipment.file_name FROM chlorinators INNER JOIN chlorinator_equipment ON chlorinators.chlorinator_index = chlorinator_equipment.chlorinator_index INNER JOIN equipment ON chlorinator_equipment.equipment_index = equipment.equipment_index WHERE chlorinators.model_name= "2075 GS"'; var_dump($query); echo '<br><br>'; if ($result = $dbhandle->query($query)) {?> <br><br><?php var_dump($result->fetch_assoc()); printf("<p style='font-family:sans-serif; text-align: center;'>The components of the %s are listed below</p><table id='form' name='pump' style='margin: auto; padding: auto'>", $_POST["chlorinator"]); while($row = $result->fetch_assoc()) { printf ("<div><tr><td>%s</td><td><a href='%s' download>Download</a></td></tr>", $row["name"],$row["cutsheet_url"]); } printf('</table>'); } ?> </code></pre> <p>For this particular example I'm using the value '2075 GS' as the chlorinator value. It is generally passed via change on a selection box, so the values are hard coded and correct. The output of this specific example is:</p> <blockquote> <p>string(403) "SELECT chlorinators.model_name, equipment.name, equipment.cutsheet_url, chlorinators.pump_specific, equipment.file_name FROM chlorinators INNER JOIN chlorinator_equipment ON chlorinators.chlorinator_index = chlorinator_equipment.chlorinator_index INNER JOIN equipment ON chlorinator_equipment.equipment_index = equipment.equipment_index WHERE chlorinators.model_name= "2075 GS""</p> <p>string(404) "SELECT chlorinators.model_name, equipment.name, equipment.cutsheet_url, chlorinators.pump_specific, equipment.file_name FROM chlorinators INNER JOIN chlorinator_equipment ON chlorinators.chlorinator_index = chlorinator_equipment.chlorinator_index INNER JOIN equipment ON chlorinator_equipment.equipment_index = equipment.equipment_index WHERE chlorinators.model_name= "2075 GS""</p> </blockquote> <p>I don't see any difference between the two outputs; any idea as to where the one character difference is and how I can eliminate it so that my query will properly work? Any help is greatly appreciated.</p> |

Cursor jumps, disappearing symbols when you're typing, <code>onChange</code> calls with incorrect <code>EditorState</code>, you name it.</p> <p>People are reporting problems like this in clojurians/reagent Slack channel, but it seems there's no solution so far.</p> <p>Any help would be greatly appreciated.</p> |

40,739,479 | 0 | <p>Okay, @Arnold I'm not sure that I fully understand your question, but in case it helps, you could use the <code>background-size</code> and <code>background-repeat</code> properties, for example:</p> <pre><code><div style="background-image: url('file.png'); background-size: x% y%; background-repeat: repeat-x;"> </code></pre> <p>Where x and y are percentages that represent the width and the height, respectively. So if you have an image that is portrait (taller than it is wide), set y to 100% and x to a percentage evenly divisible by 100% that best represents the aspect ratio (so something like 10, 20, 25, 33.3, 50%). This way, your image will repeat evenly along the x-axis, but won't need to on the y because it's taking up 100% of the element height.</p> <p>(Conversely, if the image is landscape (wider than it is tall), x would be 100% and y would be divisible by 100 and use <code>repeat-y</code> instead of <code>repeat-x</code>.)</p> <p>This might take some tinkering and depends on whether the image is something that will look ok with its aspect ratio being off somewhat. It may or may not be the solution you need, but I figured it's worth a shot.</p> |

6,478,410 | 0 | <p>If I have not wrongly misinterpreted your question, then here is what you want to do - </p> <ul> <li>Extract a .tgz file which may have more .tgz files within it that needs further extraction (and so on..) </li> <li>While extracting, you need to be careful that you are not replacing an already existing directory in the folder.</li> </ul> <p>If I have correctly interpreted your problem, then...<br> Here is what my code does - </p> <ul> <li>Extracts every .tgz file (recursively) in a separate folder with the same name as the .tgz file (without its extension) in the same directory.</li> <li>While extracting, it makes sure that it is not overwriting/replacing any already existing files/folder.</li> </ul> <p>So if this is the directory structure of the .tgz file - </p> <pre><code>parent/ xyz.tgz/ a b c d.tgz/ x y z a.tgz/ # note if I extract this directly, it will replace/overwrite contents of the folder 'a' m n o p </code></pre> <p>After extraction, the directory structure will be - </p> <pre><code>parent/ xyz.tgz xyz/ a b c d/ x y z a 1/ # it extracts 'a.tgz' to the folder 'a 1' as folder 'a' already exists in the same folder. m n o p </code></pre> <p>Although I have provided plenty of documentation in my code below, I would just brief out the structure of my program. Here are the functions I have defined - </p> <pre><code>FileExtension --> returns the extension of a file AppropriateFolderName --> helps in preventing overwriting/replacing of already existing folders (how? you will see it in the program) Extract --> extracts a .tgz file (safely) WalkTreeAndExtract - walks down a directory (passed as parameter) and extracts all .tgz files(recursively) on the way down. </code></pre> <p>I cannot suggest changes to what you have done, as my approach is a bit different.

34,706,311 | 0 | why does every process(or any address space) has its own page table? <ol> <li><p>Why does every process (or any address space) have its own page table? </p> <ul> <li>I think that if we use a single page table for all processes, then a process can access the address apace of other processes so we need a separate page table for each process. This means the pages which actually belong to a particular process will be valid and all other pages which belong to some other's address space will be marked invalid. Am I correct? </li> <li>If yes, then why didn't we add one more field as "process ID" to the page table to distinguish the address space of every process?</li> <li>If not, why does every process (or any address space) have its own page table?</li> </ul></li> <li><p>How can multilevel paging reduce the size of the page table?</p> <ul> <li>Because we added some more page tables (in multilevel paging) as overhead, and the actual page table is also in main memory</li> </ul></li> <li><p>Suppose we did 3 levels of paging as 1 (closer to CPU)->2->3; so we have three page tables for each level.

Now which page tables are used by processes?</p> <ul> <li>All??? Then the 3rd level page table which contains the actual frames should be of the same size as the original page table (without multilevel) because it must have entries for all frames which are used by physical memory too.</li> </ul></li> </ol> |

38,984,063 | 0 | <p>This is common phenomena occurring if the class frequencies are unbalanced, e.g. nearly all samples belong to one class. For examples if 80% of your samples belong to class "No", then classifier will often tend to predict "No" because such a trivial prediction reaches the highest overall accuracy on your train set. </p> <p>In general, when evaluating the performance of a binary classifier, you should not only look at the overall accuracy. You have to consider other metrics such as the ROC Curve, class accuracies, f1 scores and so on.</p> <p>In your case you can use sklearns <a href="http://scikit-learn.org/stable/modules/generated/sklearn.metrics.classification_report.html" rel="nofollow">classification report</a> to get a better feeling what your classifier is actually learning:</p> <pre><code>from sklearn.metrics import classification_report print(classification_report(y_test, model_1.predict(X_test))) print(classification_report(y_test, model_2.predict(X_test))) </code></pre> <p>It will print the precision, recall and accuracy for every class. </p> <p>There are three options on how to reach a better classification accuracy on your class "Yes"</p> <ul> <li>use sample weights, you can increase the importance of the samples of the "Yes" class thus forcing the classifier to predict "Yes" more often</li> <li>downsample the "No" class in the original X to reach more balanced class frequencies </li> <li>upsample the "Yes" class in the original X to reach more balanced class frequencies</li> </ul> |
15,005,825 | 0 | <p>How about putting the Direction and Type as members of the enum, something like this:</p> <pre><code>public enum State { ONE_STATE(Direction.LEFT, Type.BIG), SECOND_STATE(Direction.RIGHT, Type.SMALL); THIRD_STATE(Direction.UP, Type.SMALL); private Direction direction; private Type type; private State(Direction direction, Type type) { this.direction = direction; this.type = type; } public static State getState(Direction dir, Type type) { for (State state : values()) { if (state.direction == dir && state.type == type) { return state; } } return THIRD_STATE; } } </code></pre> <p>Note that this will not work if there is more than one different combination for each enum. In that case, you will need to use some sort of lookup table as suggested by another poster. For example, you could use a <code>Map<Pair<Direction, Type>, State></code>. (Java doesn't have a <code>Pair<T, U></code> class, but you can easily make one or find one in lots of different libraries.)</p> |
