[ "Installing wordpress in a different directory than root because another CMS is installed there", "I have a weird situation with a client:\n\nThe root directory has a custom built CMS serving the site.\nThey want to rebuild the site in stages as it is very big.\nSo they want the new site in Wordpress and for the first stage just to build specific pages in Wordpress.\nSo obviously I would install WP in a sub directory or a different directory than root.\nBUT, they want the pages served by WP to not indicate a different URL path so if we create a page called page1 the URL needs to be:\nhttp://domainname.com/page1 not \nhttp://domainname.com/wp/page1\n\nObviously if a browser navigates to:\nhttp://domainname.com/page1\nthe CMS installed in root will try to serve the page and return a 404.\n\nSo my thinking is it must be possible to add a bunch of rules in the root folder htaccess (or with PHP) that check a list if the incoming request is for a URL we indicated in the list is meant to be served from WP, then to pull the files from the WP sub directory (bypassing the CMS installed in root) and rewrite the URL to root.\n\nSo if I go with my browser to:\nhttp://domainname.com/page1\nI will get the WP page\nand if I go with the browser to:\nhttp://domainname.com/wp/page1\nit will server that page but with a 301 redirect to:\nhttp://domainname.com/page1\n\nMakes sense?

[ "How do you handle arbitrary namespaces when querying over Linq to XML?", "I have a project where I am taking some particularly ugly \"live\" HTML and forcing it into a formal XML DOM with the HTML Agility Pack. What I would like to be able to do is then query over this with Linq to XML so that I can scrape out the bits I need. I'm using the method described here to parse the HtmlDocument into an XDocument, but when trying to query over this I'm not sure how to handle namespaces. In one particular document the original HTML was actually poorly formatted XHTML with the following tag:\n\n<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\">\n\n\nWhen trying to query from this document it seems that the namespace attribute is preventing me from doing something like:\n\nvar x = xDoc.Descendants(\"div\");\n// returns null\n\n\nApparently for those \"div\" tags only the LocalName is \"div\", but the proper tag name is the namespace plus \"div\". I have tried to do some research on the issue of XML namespaces and it seems that I can bypass the namespace by querying this way:\n\nvar x = \n (from x in xDoc.Descendants()\n where x.Name.LocalName == \"div\"\n select x);\n// works\n\n\nHowever, this seems like a rather hacky solution and does not properly address the namespace issue. As I understand it a proper XML document can contain multiple namespaces and therefore the proper way to handle it should be to parse out the namespaces I'm querying under. Has anyone else ever had to do this? Am I just making it way to complicated? I know that I could avoid all this by just sticking with HtmlDocument and querying with XPath, but I would rather stick to what I know (Linq) if possible and I would also prefer to know that I am not setting myself up for further namespace-related issues down the road.\n\nWhat is the proper way to deal with namespaces in this situation?" ]

Is there an automagical way of doing this?

And after I finished I want that lines to stay in the right place where i left that(before reload website). So I need to send that canvas to mysql data base. But here I stuck. Did I first need to create .png image and then try to send that image information to database? or somehow I can send it right off from code to database by using AJAX? I read a lot of information and I am confused right now.\n\nIf I will use method HTMLgetImageData() and HTMLputImageData() then I need to create some real image in my server? or I can take straight from the canvas? and send to mysql databse? :) \n\nso now I have Canvas in html and some script for drawing the lines: \n\n$(\".widget_body\").on(\"mousedown\", \"canvas\", function() {\n\n var id = $(this).attr(\"id\");\n var canvas = document.getElementById(id);\n var canvas,\n context,\n dragging = false,\n dragStartLocation,\n snapshot;\n\n fitToContainer(canvas);\n\n function fitToContainer(canvas){\n // Make it visually fill the positioned parent\n canvas.style.width ='100%';\n canvas.style.height='100%';\n // ...then set the internal size to match\n canvas.width = canvas.offsetWidth;\n canvas.height = canvas.offsetHeight;\n }\n\n\n function getCanvasCoordinates(event) {\n var x = event.clientX - canvas.getBoundingClientRect().left,\n y = event.clientY - canvas.getBoundingClientRect().top;\n\n return {x: x, y: y};\n }\n\n function takeSnapshot() {\n snapshot = context.getImageData(0, 0, canvas.width, canvas.height);\n }\n\n function restoreSnapshot() {\n context.putImageData(snapshot, 0, 0);\n }\n\n\n function drawLine(position) {\n context.beginPath();\n context.moveTo(dragStartLocation.x, dragStartLocation.y);\n context.lineTo(position.x, position.y);\n context.stroke();\n }\n\n function dragStart(event) {\n dragging = true;\n dragStartLocation = getCanvasCoordinates(event);\n takeSnapshot();\n }\n\n function drag(event) {\n var position;\n if (dragging === true) {\n restoreSnapshot();\n position = getCanvasCoordinates(event);\n drawLine(position);\n }\n }\n\n function dragStop(event) {\n dragging = false;\n restoreSnapshot();\n var position = getCanvasCoordinates(event);\n drawLine(position);\n }\n\n function clearCanvas(event) {\n context.clearRect(0, 0, canvas.width, canvas.height);\n }\n\n\n context = canvas.getContext('2d');\n context.strokeStyle = 'purple';\n context.lineWidth = 4;\n context.lineCap = 'round';\n\n canvas.addEventListener('mousedown', dragStart, false);\n canvas.addEventListener('mousemove', drag, false);\n canvas.addEventListener('mouseup', dragStop, false);\n canvas.addEventListener('dblclick', clearCanvas, false);\n });\n\n\nMaybe somebody can suggest something to me? Maybe something about next steps?What should I have to do from this moment?" ]

[ "Splitting up connections between groups", "I would like to know the best way to split up the connection command. I have two groups that I want to be modular, an inner group and an outer group. I want the inner group to be a kind of black box where I can switch out or change the inner group without changing all the connections for the outer group. I just want the outer group to have to know the inputs and outputs of the inner group. For an example: \n\nimport numpy as np\nfrom openmdao.api import Group, Problem, Component, IndepVarComp, ExecComp\n\nclass C(Component):\n def __init__(self, n):\n super(C, self).__init__()\n self.add_param('array_element', shape=1)\n self.add_output('new_element', shape=1)\n\n def solve_nonlinear(self, params, unknowns, resids):\n unknowns['new_element'] = params['array_element']*2.0\n\nclass MUX(Component):\n def __init__(self, n):\n super(MUX, self).__init__()\n for i in range(n):\n self.add_param('new_element' + str(i), shape=1)\n self.add_output('new_array', shape=n)\n self.n = n\n\n def solve_nonlinear(self, params, unknowns, resids):\n new_array = np.zeros(n)\n for i in range(n):\n new_array[i] = params['new_element' + str(i)]\n unknowns['new_array'] = new_array\n\nclass GroupInner(Group):\n def __init__(self, n):\n super(GroupInner, self).__init__()\n for i in range(n):\n self.add('c'+str(i), C(n))\n self.connect('array', 'c'+str(i) + '.array_element', src_indices=[i]) \n self.connect('c'+str(i)+'.new_element', 'new_element'+str(i))\n\n self.add('mux', MUX(n), promotes=['*'])\n\nclass GroupOuter(Group):\n def __init__(self, n):\n super(GroupOuter, self).__init__()\n self.add('array', IndepVarComp('array', np.zeros(n)), promotes=['*'])\n self.add('inner', GroupInner(n), promotes=['new_array'])\n for i in range(n):\n # self.connect('array', 'inner.c'+str(i) + '.array_element', src_indices=[i])\n self.connect('array', 'inner.array', src_indices=[i])\nn = 3\np = Problem()\np.root = GroupOuter(n)\np.setup(check=False)\np['array'] = np.ones(n)\np.run()\n\nprint p['new_array']\n\n\nWhen I run the code I get the error that: \n\nNameError: Source 'array' cannot be connected to target 'c0.array_element': 'array' does not exist.\n\n\nTo try to solve this I made 'array' an IndepVarComp in the GroupInner group. However, when I do this I get the error:\n\nNameError: Source 'array' cannot be connected to target 'inner.array': Target must be a parameter but 'inner.array' is an unknown.\n\n\nI know that if I just make the full connection: self.connect('array', 'inner.c'+str(i) + '.array_element', src_indices=[i]) then it will work. But like I said I want GroupInner to be kind of a black box where I don't know what groups or components are in it. I also can't just promote all because the array_elements are different. Is it possible to do this or do you have to do the entire connection in one command?" ]
