"How to display old articles?",
"I wanted to set created date of the articles, so I set the date of the articles to 2012-2-1 but after the setting the date of the articles it's not displaying in the front-end anymore now.\n\nAfter doing a deep dive into this I saw the article in the back-end it isn't being published. It's saying published, but has expired.\n\nSo, can I not publish the old-dated articles?\n\nPlease, help me on this topic. Thank you."

"Optimal method to find perpendicular distance between numpy poly1d and arbitrary point",
"I have a numpy.poly1d that can be any arbitrary 1d polynomial. Given an arbitrary point P, I wish to find the perpendicular distance between the curve and the point, and the point on the curve where the shortest distance line intersects the curve, if the point P does not lie on the polynomial itself\nNow I can do something like the question Distance between a point and a curve in python, by sampling a set of points. But I believe that won't be fast enough considering that I have <100000 polynomials and <1000000 points per polynomial that I wish to find that distances to. Can someone suggest a more optimal method?\nHere is a sample image illustration of what I am looking for. Basically, given P and B(t) I wish to find the length of g(x) and point Q."

"Using jQuery .load() with aspx",
"So I'm fairly new to the .NET framework, but what I'm trying to do is execute the following jQuery code:\n\n $(document).on('click', 'a[data-link]', function () {\n var $this = $(this);\n url = $this.data('link');\n $(\"#imagePreview\").load(\"imageProcess.aspx?\"+url);\n\n\nwhere url holds something like \"model=2k01&type=black&category=variable\".\nUnfortunately this doesn't work, becuase when I do something as simple as a Response.Write() in the aspx file, the div tag imagePreview doesn't do anything. However, removing the ? + url part works, but then I can't send any data over to the aspx file. I'm doing it this way because every link a[data-link] has different data that's being sent over, and I need to find a dynamic way to achieve this. Any suggestions would be much appreciated.\n\nUPDATE:\nHere is the part in my html code that is generating the url stuff:\n\n<a class='modelsBlue' href = '#' data-link='model=\" + $(this).find('model').text() + \"&type=\" + category + \"'>\" + $(this).find(\"model\").text() + \"</a>\n\n\nand #image preview is in my code as:\n\n<div id = \"imagePreview\"></div>\n\n\nWhen I try to run the code above, i get the following error which seems to be coming from the jQuery.js file:\n\nMicrosoft JScript runtime error: Syntax error, unrecognized expression: &type=AutoEarly\n\n\nHere is the imageProcess.aspx.cs file, which right now is just outputting all images in the directory:\n\nnamespace ModelMonitoring\n{\n public partial class imageProcess : System.Web.UI.Page\n {\n protected void Page_Load(object sender, EventArgs e)\n {\n Response.Write(\"test\");\n foreach (var f in Directory.GetFiles(Directory.GetCurrentDirectory()))\n {\n Response.Write(f);\n Response.Write(\"<br />\");\n }\n }\n }\n}\n\n\nSECOND UPDATE:\nI don't get the error running in chrome or firefox, but the files are not being output."

Thanks for any hint!\n\n(Please note, the ordering is just a dumb example, I just need to know how to integrate Java constants into the XML definition of an array)"

"Convert C char to UTF-16 for transmission over network",
"I'm writing a program that will interface with another machine running Java, and I need to send character arrays over the network. On the receiving end, the Java program uses DataInputStream's readChar() function and expects characters. However, since characters are stored as 1 byte in C, I'm having some trouble writing to the network.\n\nHow would I go about converting this?\n\nThe actual protocol specification is like so:\n\nshort: Contains length of char array\nchar 1, 2, 3...: The characters in the array\n\n\nFor background information, my short conversion is like so:\n\nchar *GetBytesShort(short data)\n{\n short net_data = NET_htons(data);\n char *ptr = (char *) malloc(sizeof(short));\n memcpy(ptr, &net_data, sizeof(short));\n return ptr;\n}\n\n\nI've tested it on the receiving end in Java, and the short does get sent over correctly with the correct length, but the character array does not.\n\nThanks in advance!"

If I changes the value of Question 1 to \"New Question 1\". The display of the multiple select remains the same. But if you click it, you will see the options has already been changed. The changed option is not selected. This is not correct. I want the changed option is selected and the display of this multiple select box also changes to \"1-New Question 1, 2-Question 2\".\n\nI hope I explain my requirement clearly.\nThank you."

My code: \n\nIncidentBoard:\n\nimport React from 'react';\nimport Incident from './Incidents';\nimport testData from './testdata';\n\nclass IncidentBoard extends React.Component {\n\n constructor(props) {\n super(props);\n this.state = {\n data: testData.features,\n filtered: []\n }\n }\n\n componentWillMount() {\n\n var filtered = this.state.data.filter( (incident, i) => {\n return incident.properties.event_type === 'Crash';\n })\n\n console.log(filtered);\n this.setState({filtered}) \n\n } \n\n render() {\n return <div>\n {this.state.filtered.map((incident, i) => {\n return <Incident id={i} description=\"swagg\" />\n })}\n </div>\n }\n}\nexport default IncidentBoard;\n\n\nIncident (which is currently mostly empty):\n\nimport React from 'react';\n\nclass Incident extends React.Component {\n\n render() {\n return <div><h1>test</h1></div>\n }\n\n}\n\nexport default Incident;\n\n\nWhen running this, it causes an infinite loop where componentWillMount() is run without end. I have also noticed that if I replace the Incident component in the render function in IncidentBoard that the error no longer happens. \n\nEDIT: More code\n\nindex.js\n\nimport React from 'react';\nimport ReactDOM from 'react-dom';\nimport IncidentBoard from './Incidents';\n\nReactDOM.render(\n <IncidentBoard />, document.getElementById('react-container')\n)\n\n\ntestData is a just a big JSON object."

"How does one create a validator that depends on more than one value for Zend_Form?",
"I've got a form that has a single text field (for company):\n\nclass Cas_Form_Company extends Zend_Form\n{\n\n public function init()\n {\n $this->addElement('hidden', 'id');\n $this->addElement('text', 'name', array('label' => 'Name'));\n $this->addElement('submit', 'submit', array('label' => 'Create'));\n\n $name = $this->getElement('name');\n $name->addValidator('stringLength', false, array(2,45));\n $name->addValidator(new Cas_Model_Validate_CompanyUnique());\n\n $this->setMethod('post');\n $this->setAction(Zend_Controller_Front::getInstance()->getBaseUrl() .

The problem comes in when I want to allow editing of companies. This is because for an edit operation, while the company name needs to be unique, a form containing the name already pertaining to the given ID isn't an edit at all (and therefore is valid). That is, the form is valid if either the name doesn't already exist in the database, or the name given matches the name already assigned to that ID.\n\nHowever, writing this as a validator seems to be problematic, because the validator only gets the value it's working on -- not the ID in question.\n\nHow does one write a validator for this sort of thing?"

"Filtering elements while reading .plist array into NSArray",
"First post - hope I'm doing it right!\n\nI have a file, lexicon.plist, containing an array of about 250K words. I want to load all words of length 'n' into an NSArray.\n\nI know about the NSArray instance method:\n\n\n(id)initWithContentsOfFile:(NSString *)aPath\n\n\nbut I don't see any way to intervene in the process of reading the file into the NSArray. The only solution I can see is to first load the entire lexicon into one NSArray, and then run through it in a loop selecting the elements of length 'n'.\n\nI'm very new at Cocoa, but I have come across some methods that perform some sort of iterative task, that accept a \"block\" of code that is invoked at each iteration. I was wondering if such a functional variant of initWithContentsOfFile might exist, or how else I might iteratively read an array from a .plist file and filter the elements I'm interested in.\n\n[And if you're wondering if this might be a case of premature optimization - it is ;-) But I'd still like to know.]"

"Storing SSIS Execution Results in to a table",
