Imagine you are a highly-indemand actor, who has been presented with offers to star in n different movie projects under development. Each offer comes specified with the first and last day of filming. To take the job, you must commit to being available throughout this entire period. Thus you cannot simultaneously accept two jobs whose intervals overlap.\nFor an artist such as yourself, the criteria for job acceptance is clear: you want to make as much money as possible. Because each of these films pays the same fee per film, this implies you seek the largest possible set of jobs (intervals) such that no two of them conflict with each other.\nFor example, consider the available projects in Figure 1.5 [above]. We can star in at most four films, namely “Discrete” Mathematics, Programming Challenges, Calculated Bets, and one of either Halting State or Steiner’s Tree.\nYou (or your agent) must solve the following algorithmic scheduling problem:\nProblem: Movie Scheduling Problem\nInput: A set I of n intervals on the line.\nOutput: What is the largest subset of mutually non-overlapping intervals which can be selected from I?\n\nI wonder, is this an instance of the TSP (perhaps a simplified one)?" ]

I checked to make sure all years had the same number of data points and all states had the same number of data points, so I don't think there was an issue there after that.\nOnce I added the NA's, however, I started getting the error &quot;(p &lt;- ncol(X)) == ncol(Y) is not TRUE&quot;, which seems to be due to having NA values in factor columns. Going off of recommendations on other posts, I used na.omit to fix the issue, but then I got the &quot;variable lengths differ&quot; error again (seems like an endless cycle that I don't know how to fix yet).\nIf anyone could guide me as to how I should proceed, I would be super grateful!

Unfortunately, I cannot get past making models in Padrino, so I'm wondering if it's just a cause of beta software, or just error on my part.\n\nI start off by creating my project with Cucumber and RSpec for testing and Sequel for my ORM.\n\n$ padrino g project test -d sequel -t cucumber -c sass -b\n\n\nNext, I create some model and migration:\n\n$ padrino g model user\n\n# ./db/migrate/001_create_users.rb\nSequel.migration do\n change do\n create_table :users do\n primary_key :id\n String :name\n String :password\n end\n end\nend\n\n\nNext, of course, comes the spec. For sake of example, just something simple:\n\n# ./spec/models/user_spec.rb\nrequire 'spec_helper'\n\ndescribe User do\n it 'can be created' do\n user = User.create\n end\nend\n\n\nNow, migrate and run the spec:\n\n$ padrino rake sq:migrate:up\n$ rspec spec\n\nF\n\nFailures:\n\n 1) User can be created\n Failure/Error: user = User.create\n Sequel::DatabaseError:\n SQLite3::SQLException: no such table: users\n # ./spec/models/user_spec.rb:5:in `block (2 levels) in &lt;top (required)&gt;'\n\nFinished in 0.00169 seconds\n1 example, 1 failure\n\nFailed examples:\n\nrspec ./spec/models/user_spec.rb:4 # User can be created\n\n\nThis is very confusing. It was at this point that I thought going into the Padrino console would help me solve this strange issue. I was wrong.\n\n$ padrino c\n&gt; User.create\n =&gt; #&lt;User @values={:id=&gt;1, :name=&gt;nil, :password=&gt;nil}&gt;\n&gt; User.all\n =&gt; [#&lt;User @values={:id=&gt;1, :name=&gt;nil, :password=&gt;nil}&gt;]\n\n\nFair enough results, but then I try it with the test environment:\n\n$ padrino c -e test\n&gt; User.create\n Sequel::DatabaseError: SQLite3::SQLException: no such table: users\n\n\nI know that in RoR, to get integrated models to run, you have to do something like rake db:test:prepare, but doing padrino rake -T doesn't seem to reveal any equivalent (tested with Sequel, DataMapper, and ActiveRecord; none seem to have the db:test:prepare). So, my question is: how do I get integrated database tests running within Padrino?" ]

[ "Calling multiple stored procedures from stored procedure - sql while loop", "I often hear that while loops are as bad as cursors, which I did not believe to be true. Is it better from a performance standpoint to call multiple stored procedures from C#, or allow a stored procedure to parse XML data and call procedures in a looping fashion? Is there a better way to call an unknown number of stored procedures in SQL than looping? \n\nLet me explain\n\nI have to design and implement a vendor messaging system. There is a third party company sending along XML messages to the recipient that originated from the sender. My company might be the sender or the recipient at any given time. \n\nI have come up with a design that uses a SQL while loop to run stored procedures, but I'm worried that it might not perform well when faced with a large number of loops. \n\nThe basic idea is:\nSender --> third party (message system) --> receiver\n\nMy problem may occur when my company is the receiver: \n\n\nSender sends message to third party company \nThird party company sends message to my company\nWCF Service receives request from third party company\nA stored procedure is called, passing the xml of the message received to be parsed\nThis stored procedure parses xml and finds messages in the XML\nWhile loop goes through each message and calls a stored procedure to update information, passing the ID of the instance of the message. \n\n\nThe message XML is something like this:\n\n&lt;envelope&gt;\n &lt;to&gt;&lt;/to&gt;\n &lt;from&gt;&lt;/from&gt;\n ...\n &lt;messages&gt;\n &lt;message&gt;\n &lt;id&gt;&lt;/id&gt;\n ...\n &lt;params&gt;\n &lt;param&gt;\n &lt;Name&gt;&lt;/Name&gt;\n &lt;Value&gt;&lt;/Value&gt;\n &lt;param&gt;\n ...\n &lt;/params&gt;\n &lt;/message&gt;\n ...\n &lt;/messages&gt;\n&lt;/envelope&gt;\n\n\nI can receive or send one or more messages in each transmission of XML. There could potentially be multiple messages received at once. A requirement of the third party company which handles sending and receiving the XML is that we always respond with Success or Fail. We have a 60 second timeout window to respond. Due to these limitations, I am naturally afraid that I won't be able to do all the processing I need to do in the time limit, causing a timeout. \n\nSo if I find message 1, 2 and 3 in one transmission, I would have to run stored procedure 1, 2 and 3. I have a temp table filled with message ID and stored procedure to run. \n\nSo the While loop would be basically (didn't check validity of this part, just free-handed it as I don't have the SP handy)\n\nWhile select count(*) from #temptable &gt; 0\nbegin\n select top 1 @idMessage = idMessage, @spToRun = spToRun from #temptable\n exec @spToRun @idMessage\n\n delete from #temptable where idMessage = @idMessage\n select @idMessage = null, @spToRun = null\nend\n\n\nI'm afraid to put this into production and then find out it runs far, far too slowly.

[ "Leave System Balance on a HR application Laravel", "I'll just head on to the question directly, I'm currently trying to build an HR(Human Resources) Application on Laravel and at the Leave System where a user can take a specific type of Leave(Vacation and such), I would like to create a Balance system where the user selects a date from and date to and that number in between them gets deducted from the main balance that a user has and that would be the number 20 which I added to my user table on a field called leave_balance(the number is set by default as 20 when a user is created).\nNow except deducting the number I would also like to add a function somehow that adds a specific number to the leave_balance every day ex 0.05 I am suspecting I can do this with carbon but I have not the slightest idea how since im relatively new to Laravel\nSo this is the Leave Table(it is not connected by a foreign key with the user's table):\n\nid\nuser_id\nfrom\nto\ntype\ndescription\nstatus\nmessage\n\nThe user_id is only there to store the id of the authenticated user who creates a leave it is not related by a foreign key\nThis is what I was thinking of adding in the LeaveController:\n// checks for table if employee leave is at 0\n$employee = DB::table('leaves')-&gt;where('id', $id)-&gt;where('leave', 0)-&gt;get()-&gt;all();\n$employeeObj = DB::table('leaves')-&gt;where('id', $id)-&gt;get()-&gt;all();\n\n// init for needed condition\n$leaveBool = false;\nif(sizeof($employee) &lt; 1) {\n $leaveBool = true;\n}\n\n// leave is not at 0\nif(!$leaveBool) {\n DB::table('leaves')-&gt;update([\n 'id' =&gt; $id,\n 'leave' =&gt; $employeeObj['leaves'] - 1,\n ]);\n}\n\nI would like to fix this code so that I can add this in the Leave Controller(also if it's possible to explain to me where exactly I should put such a code in the controller) by fix I mean to not just removed -1 but the number between &quot;from&quot; and &quot;to&quot;\nI'm not sure if these are helpful but I will post them too just to make it easier to see,\nThis is the Leave Model:\nclass Leave extends Model\n{\n use Notifiable;\n\n protected $guarded=[];\n \n public function user(){\n return $this-&gt;belongsTo(User::class,'user_id','id'); \n }\n}\n\nThis is the view of the Leave\n&lt;div class=&quot;card-body&quot;&gt;\n &lt;form method=&quot;POST&quot; action=&quot;{{route('leaves.store')}}&quot;&gt;\n @csrf\n\n &lt;div class=&quot;form-group&quot;&gt;\n &lt;label&gt;From Date&lt;/label&gt;\n &lt;div class=&quot;col-md-6&quot;&gt;\n &lt;input class=&quot;datepicker&quot; type=&quot;text&quot; class=&quot;form-control @error('from') is-invalid @enderror&quot; name=&quot;from&quot; required=&quot;&quot;&gt;\n\n @error('from')\n &lt;span class=&quot;invalid-feedback&quot; role=&quot;alert&quot;&gt;\n &lt;strong&gt;{{ $message }}&lt;/strong&gt;\n &lt;/span&gt;\n @enderror\n &lt;/div&gt;\n &lt;/div&gt;\n\n &lt;div class=&quot;form-group&quot;&gt;\n &lt;label&gt;To Date&lt;/label&gt;\n &lt;div class=&quot;col-md-6&quot;&gt;\n &lt;input class=&quot;datepicker1&quot; type=&quot;text&quot; class=&quot;form-control @error('to') is-invalid @enderror&quot; name=&quot;to&quot; required=&quot;&quot;&gt;\n\n\nI used datepicker for the date, this would be a visualization of what I'm trying to achieve\n\nAlso by any means, if you have a better code or idea on how I can do this do share it your way it may probably be heaps better" ]

[ "Bootstrap Modal flashes/disappears instantly - ASP.NET gridview RowCommand", "Good morning everybody. I seem to be stuck between a rock and a hard place and fear I may be missing something incredibly simple. I am currently developing a webforms application using an ASP.NET GridView control. \n\nI have a bootstrap modal that is intended to display gridview row details through an ASP button on each row. I understand there are other posts on this topic but my issue seems to be a little different. \n\nThe button I use to toggle the bootstrap modal is in an asp control:\n\n&lt;asp:TemplateField HeaderText=\"Approval Information\"&gt;\n &lt;ItemTemplate &gt;\n &lt;asp:Button Text=\"Stats\" runat=\"server\" CommandName=\"ApprovalModal\" type=\"button\" class=\"btn btn-info\" OnClientClick=\"return false\" data-toggle=\"modal\" data-target=\"#myModal\"/&gt;\n &lt;/ItemTemplate&gt;\n&lt;/asp:TemplateField&gt;\n\n\nThis button can currently toggle my modal just fine. The problem is, I want to subscribe to the RowCommand event in GridView so I can change the text of the ASP Literal control in the modal to display Row stats for each individual row when clicked:\n\n protected void gvwApprovals_RowCommand(object sender, GridViewCommandEventArgs e)\n {\n if (e.CommandName == \"ApprovalModal\")\n {\n approvalModalText.Text = \"Some Unique Row Stats\";\n approvalModalText.Visible = true;\n }\n }\n\n\nThe only way I can subscribe to this event and have it fire is if I take out OnClientClick=\"return false\"\n\nHowever, if I take that out of the ASP button, I subscribe to the event, but then the bootstrap modal now just flashes and disappears. \n\nHere is my modal:\n\n&lt;!-- Modal --&gt;\n&lt;div class=\"modal fade\" id=\"myModal\" role=\"dialog\"&gt;\n &lt;div class=\"modal-dialog\"&gt;\n &lt;!-- Modal content--&gt;\n &lt;div class=\"modal-content\"&gt;\n &lt;div class=\"modal-header\" style=\"display: block;\"&gt;\n &lt;button type=\"button\" class=\"close\" data-dismiss=\"modal\"&gt;&amp;times;&lt;/button&gt;\n &lt;h4 class=\"modal-title\"&gt;Approval Information - Relevant Statistics&lt;/h4&gt;\n &lt;/div&gt;\n &lt;div class=\"modal-body\" &gt;\n &lt;asp:Literal ID=\"approvalModalText\" runat=\"server\" Text='placeholder' Visible=\"false\" /&gt;\n &lt;/div&gt;\n &lt;div class=\"modal-footer\"&gt;\n &lt;button type=\"button\" class=\"btn btn-default\" data-dismiss=\"modal\"&gt;Close&lt;/button&gt;\n &lt;/div&gt;\n &lt;/div&gt;\n &lt;/div&gt;\n&lt;/div&gt;\n\n\nWhat am I missing here? Available to clarify any further questions. Fairly new to ASP controls in general, so I'm not sure if there's something super simple I might just be totally unaware of. \n\nEDIT: \n\nOf course there is a post that happens to fire the RowCommand which reloads the page and the modal disappears. Thanks to Alex for pointing it out to me in the comments (I knew it was something dumb and simple). Must use RegisterStartupScript in Row Command handler to show the modal rather than just doing a straight toggle. jQuery here I come." ]

[ "Meteor.js connects to, but does not publish to, remote mongo server?", "So I'm connecting a develop mode instance of meteor to a remote mongo via the recommended method of including MONGO_URL::@: in order to have persistent collections for saving user state that will allow a user to come back later by loading what they had input into the app. I can see several connections from the meteor server on the mongo server.\n\nHowever, when running the app, no collections appear on the mongo server. Both \"Show Collections\" and db.getCollections() return nothing. \n\nIf I kill the app process and run meteor again without the remote connection, the collections appear just fine in the mongo instance that meteor starts.\n\nIs there something special I need to do in the code with meteor to properly push collections to the remote instance?
