"Importing string from HTML into markdown parser",

Why is this? Does the string format of .innerHTML do something I am missing?\n\njsFiddle: http://jsfiddle.net/5p8be1b4/\n\nMy HTML:\n\n<div id=\"editor\">\n <div class=\"contentTarget\"></div>\n <div class=\"contentSource\">#Introduction:\\nHere you can write some text.</div>\n</div>\n\n\ndiv.contentTarget should receive HTML, parsed markdown.

"Trying to get a loop running concurrently with web.py",
"At this stage in my little project, I want to get web.py to display some information retrived from some sensors attached to my Raspberry Pi. I want the information to get retrieved regularly, so I put a loop at the bottom of my code that refreshes the sensors using my library, sticks the readings in a dict and sleeps for 10 seconds.\n\nwhile True:\n onewiretemp.refreshSensor()\n temperatures = onewiretemp.sensorTemp\n time.sleep(10)\n\n\nUnfortunately, the side effect of this is that when I run my program and try loading a page, my loop runs and the page never loads. I also have to manually kill the process to stop it. I assume this is because the loop is running indefinitely.\n\nThe rest of my code is basically the tutorial and some templating stuff from the web.py website. That part works when I disable the loop and manually add in the data formatted the same as the output from my onewiretemp module. \n\nIs there a better way of doing this that doesn't break everything?"

"Redirecting from domain to category in wordpress",
"I am running a multisite WoprdPress install where I have configured my install to use sub-domains.\n\n\n I have registered and added one domain domain-a which is my main site.\n \n I have recently registered two main domains, domain-a and domain-c, and I have pointed their DNS records IP address of my multisite.\n\n\nI need kazisport.co.za and kazisportsoccer.co.za to redirect to a category in phakathi.co.za.\n\ni.e:\n\nkazisport.co.za and kazisportsoccer.co.za\n\nredirect to:\n\n\n http://phakathi.co.za/category/sport/\n\n\nThe first option I tried was creating a second site in my multisite network and mapped the two domains to the site. Then I activated a theme. In the theme I used PHP redirect code to redirect to the category in domain-a like this:\n\n<?php\nif($_SERVER['HTTP_HOST'] == 'domain-b.co.za' || $_SERVER['HTTP_HOST'] == 'domain-c.co.za')\n{\n header(\"Location: http://domain-a.co.za/category/sport/\");\n exit;\n}\n\n?>\n\n\nThat resulted in a hit and miss in a sense that sometimes the redirection would work and sometimes it wouldn’t work.\n\nThen I replaced the the PHP redirect code with JavaScript like this:\n\n<html>\n<head>\n<script>\nfunction gotoPage()\n{\n var dns1 = \"domain-b.co.za\";\n var dns2 = \"domain-c.co.za\";\n var urlloc = location.href;\n var loc = urlloc.toLowerCase();\n\n if (loc.indexOf(dns1) != -1){\n location.href=\"http://domain-a.co.za/category/sport/\";\n }\n else if (loc.indexOf(dns2) != -1){\n location.href=\"http://domain-a.co.za/category/sport/\"; \n }\n}\n</script>\n<body onLoad=\"gotoPage()\">\n</body>\n</html>\n\n\nThat also resulted in hit and miss. Sometimes the redirection would work and sometimes it would not work.\nThen I tried htaccess redirect like this:\n\n# BEGIN WordPress\n<IfModule mod_rewrite.c>\nRewriteEngine On\nRewriteBase /\nRewriteCond %{HTTP_HOST} ^domain-b.co.za$\nRewriteRule ^$ http://domain-a.co.za/category/sport/$1 [L,R=301]\nRewriteRule ^(server-info|server-status) - [L]\nRewriteRule ^index\\.php$ - [L]\n\n# add a trailing slash to /wp-admin\nRewriteRule ^wp-admin$ wp-admin/ [R=301,L]\nRewriteCond %{REQUEST_FILENAME} -f [OR]\nRewriteCond %{REQUEST_FILENAME} -d\nRewriteRule ^ - [L]\nRewriteRule ^(wp-(content|admin|includes).*) $1 [L]\nRewriteCond %{REQUEST_URI} !^/php5.fastcgi/*\nRewriteRule ^(.*\\.php)$ $1 [L]\nRewriteCond %{REQUEST_URI} !^/php5.fastcgi/*\nRewriteRule . index.php [L]\n</IfModule>\n# END WordPress\n\n\nThat did not work at all. I am at a loss and I do not know what I need to do for the redirection to work. I would really appreciate any feedback.\n\nOh, I need to mention that I am using Varnish Cache."

"Scala Actors: \"Event Based programming\" vs \"thread-based programming\"",
"I am currently reading myself into the world of the actor model and its implementation with the programming language Scala. I have found two approaches to this. On the one hand the newer \"AKKA Framework\" and on the other hand \"Scala Actors\". There is also a published paper on \"Scala Actors\" by Philipp Haller and Martin Odersky in which they describe their implementation. This is obviously based on a combination of \"thread based\" and \"event based programming\". This raises for me the question what is the difference between \"thread based\" and \"event based\" and how to combine it or how it is combined in \"Scala Actors\" ?\n\nHas anyone had any experience with this ?\n\nThanks for every answer :)"

But I was advised to use the normal c2c function. So I defined the input function as a complex number with real part = sine(x) and complex part 0. \n\nThe DFT of sine(x) is supposed to be fk(-1) = cmplx(0, -0.5) and fk(1) = cmplx(0, 0.5) where fk(k) means the fourier coefficient of the k wavenumber\n\nThe output I received is as follows.\n\n -4 ( 0.0000000000000000 , 0.0000000000000000 )\n -3 ( 3.2001271327131496E-008,-0.49999998518472011 )\n -2 ( -1.0927847071684482E-008, 1.4901161193847656E-008)\n -1 ( -1.0145577183762535E-008, 1.4815279864022202E-008)\n 0 ( -1.0927847071684482E-008, 0.0000000000000000 )\n 1 ( -1.0145577183762535E-008, -1.4815279864022202E-008)\n 2 ( -1.0927847071684482E-008, -1.4901161193847656E-008)\n 3 ( 3.2001271327131496E-008, 0.49999998518472011 )\n\n\nI am getting fk(-3) = cmplx(~0, -0.5) and fk(3) = cmplx(~0, 0.5). If I increase the grid size to 16, 32 or so I get -n/2 -1 and n/2 -1 wavenumbers with the required values instead of the -1 and 1 wavenumbers. \n\nDoes this have something to do with the way FFTW stores the output in the output array ? Or am I going wrong anywhere else ?\n\nAlso, I don't seem to be getting 'proper 0' where I should be. It is instead numbers of the order of 10^(-8) which I believe is the smallest my datatype double can hold. Is that something I should be worried about ?"

Notice its not a duplicate of all the questions regarding flickering on transitions, since if alredy managed to get that working.\n\nMy viewport is as follows:\n\n<meta name=\"viewport\" content=\"user-scalable=no, height=device-height, width=device-width\">\n\n\nI've tried using javascript to set overflow: hidden while transitioning, but this has no effect on android.\n\nAny suggestion appreciated,\nThanks!"

I have found that setting the size of the char[] to 1 will not corrupt the file, just everything in it, meaning I can open the file in an archive program but all it's entries will be corrupted and unusable.

"How to perform multiple database alterations at once using NHibernate?",
"I am looking into using Fluent NHibernate in a desktop application which uses 3 different database files. (Well, 3 different types.)\n\n\nDB1 is the main database file containing tables A, B, C and D. \nDB2 is a database file containing detailed data (X samples per second, program session will receive a new file as they can grow very large) in table E.\nDB3 is a database file used to export and import data between users (contains 1 row from A, 1 from B and all of E that belongs to the given row of A and B)\n\n\nCreating this is not really a problem as the SchemaExport.Create function does this perfectly.\n\nThe problem I face is that I don't exactly know what the best way to alter my tables is. More precisely, to do multiple version updates at once. My application is currently version 1, shipping with database format version 1, next week I bump everything to version 2 - I can update the database with SchemaUpdate.Execute - and next month I bump everything to version 3 and I can do the same thing again. But I want my users to be able to update from version 1 to version 3 at once.\n\nIf I would do things manually I would create a table called version in each database file which contains a version. I would then check that field against the current version and perform ALTER table queries. For example:\n\nif (db_version < LATEST_VERSION) {\n switch (db_version + 1) {\n case 2: Execute(\"ALTER TABLE A...\"); Execute(\"UPDATE A...\"); break;\n case 3: Execute(\"ALTER TABLE B...\"); break;\n }\n}\n\n\nUsing this approach (when using the SQLite database provider directly) I would only have to foresee 1 version of my data model, 1 update service which handles everything but I would need to create my database and my data model files manually, and I would have to update at least two .db files and 2 update services (one for each db type). Which can be seen as duplicate work. (I found the database migration of Banshee an example of what I mean by this.)\n\nBy using NHibernate I eliminate the process of maintaining a database file and a data model, but the only way I can see on doing updates from 1 to 3 is to keep a legacy version of each data model and do something like:\n\nnamespace Version1 {\n public class A {}\n DoUpdate();\n}\n\nnamespace Version2 {\n public class A {}\n DoUpdate();\n}\n\n\nAm I totally looking at this the wrong way or is my case simply to complex and would I be better off using the manual approach? \nWhat would be the best solution to update and migrate from version 1 to 3 using Fluent NHibernate? Or would anyone recommend using the manual approach, and if so why?"

"Most efficient algorithm to compute a common numerator of a sum of fractions",
"I'm pretty sure that this is the right site for this question, but feel free to move it to some other stackexchange site if it fits there better.\n\nSuppose you have a sum of fractions a1/d1 + a2/d2 + … + an/dn. You want to compute a common numerator and denominator, i.e., rewrite it as p/q. We have the formula\n\np = a1*d2*…*dn + d1*a2*d3*…*dn + … + d1*d2*…d(n-1)*an\nq = d1*d2*…*dn.\n\n\nWhat is the most efficient way to compute these things, in particular, p? You can see that if you compute it naïvely, i.e., using the formula I gave above, you compute a lot of redundant things. For example, you will compute d1*d2 n-1 times. \n\nMy first thought was to iteratively compute d1*d2, d1*d2*d3, … and dn*d(n-1), dn*d(n-1)*d(n-2), … but even this is inefficient, because you will end up computing multiplications in the \"middle\" twice (e.g., if n is large enough, you will compute d3*d4 twice).\n\nI'm sure this problem could be expressed somehow using maybe some graph theory or combinatorics, but I haven't studied enough of that stuff to have a good feel for it.\n\nAnd one note: I don't care about cancelation, just the most efficient way to multiply things. \n\nUPDATE:\n\nI should have known that people on stackoverflow would be assuming that these were numbers, but I've been so used to my use case that I forgot to mention this.\n\nWe cannot just \"divide\" out an from each term. The use case here is a symbolic system. Actually, I am trying to fix a function called .as_numer_denom() in the SymPy computer algebra system which presently computes this the naïve way. See the corresponding SymPy issue. \n\nDividing out things has some problems, which I would like to avoid. First, there is no guarantee that things will cancel. This is because mathematically, (a*b)**n != a**n*b**n in general (if a and b are positive it holds, but e.g., if a == b ==-1 and n == 1/2, you get (a*b)**n == 1**(1/2) == 1 but (-1)**(1/2)*(-1)**(1/2) == I*I == -1). So I don't think it's a good idea to assume that dividing by an will cancel it in the expression (this may be actually be unfounded, I'd need to check what the code does).\n\nSecond, I'd like to also apply a this algorithm to computing the sum of rational functions. In this case, the terms would automatically be multiplied together into a single polynomial, and \"dividing\" out each an would involve applying the polynomial division algorithm. You can see in this case, you really do want to compute the most efficient multiplication in the first place.\n\nUPDATE 2:\n\nI think my fears for cancelation of symbolic terms may be unfounded. SymPy does not cancel things like x**n*x**(m - n) automatically, but I think that any exponents that would combine through multiplication would also combine through division, so powers should be canceling. \n\nThere is an issue with constants automatically distributing across additions, like:\n\nIn [13]: 2*(x + y)*z*(S(1)/2)\nOut[13]: \nz⋅(2⋅x + 2⋅y)\n─────────────\n 2 \n\n\nBut this is first a bug and second could never be a problem (I think) because 1/2 would be split into 1 and 2 by the algorithm that gets the numerator and denominator of each term. \n\nNonetheless, I still want to know how to do this without \"dividing out\" di from each term, so that I can have an efficient algorithm for summing rational functions."

I think what I have is correct...but I have a few questions because I want to better understand how it works. I've read the Microsoft documentation...but I'm still unclear on some things.\n\nI know by using SET XACT_ABORT ON; that it will handle the rollback for the tran. Does that mean I do not need to check for IF (@@TRANCOUNT > 0) in the CATCH block?\n\nThe other question...the reason I have the TRY...CATCH block is because of the WHILE loop...I'm not sure if the failed transaction will also terminate the proc, so I'm forcing it with THROW?\n\nHere's what I have: (Ignore the fact that it's an infinite loop, I'm not including the break logic to keep the example simple)\n\nSET XACT_ABORT ON;\nWHILE(1=1)\nBEGIN\n BEGIN TRY\n BEGIN TRAN;\n --DML Query 1\n --DML Query 2\n COMMIT TRAN;\n END TRY\n BEGIN CATCH\n IF (@@TRANCOUNT > 0)\n ROLLBACK TRAN;\n\n THROW;\n END CATCH\nEND\n\n\n\n\nUPDATE\n\nOkay I'm trying to figure out how to test it myself, I was having a hard time figuring out how to test it, but I think I've got it now.

"How do Iterators act when working with databases?",
"Making queries like SELECT * FROM people could create serious memory problems, i.e., as many like to call it, \"memory exceeded\".\n\nMany programmers invoke using iterators to reduce memory consumption. Iterators are a sort of \"play-n-pause video recording\", meaning that they procuce a value, they stop, they produce a value and so on, avoiding to generate all the values all at once. An example in Python could be the following:\n\ndef myIterator():\n for i in range(10):\n yield i * 2\n\n\nNow, when it comes to use iterators to fetch data from databases, I get pretty confused. I was always told to limit the number of queries toward a database because it could become a bottleneck and, using iterators, it seems to me to increment the number of queries. Is it so? How does an iterator work with database queries? Is this the well-known problem of the short bed sheet, again? In addition, what happens if, during the fetch phase with an iterators, some data is added in the database?\n\nP.S. My question isn't related to a particular programming language, but it is in general."

But before I need to do addInfo.\nFor example: the first line \"1009 1 \"Royal Queen\" 2015 160\"\nthe serial number is 1009 and if there is other ships that have the serial number ended with 9 we have to display them together.\nHere is the code that I have so far:\n\n#include <iostream>\n#include <fstream>\nusing namespace std;\nstruct ShipRecord\n{\n int serialNum;\n int shipType;\n string name;\n int year;\n int cap;\n ShipRecord *next;\n ShipRecord(int x)\n {\n serialNum = x;\n next = nullptr;\n }\n};\nconst int SIZE = 10;\nclass HashMgr\n{\n ShipRecord *head = nullptr;\n ShipRecord *tail = nullptr;\npublic:\n HashMgr()\n {\n ShipRecord * hashTable[SIZE] = {nullptr};\n\n string line;\n ifstream myfile;\n myfile.open(\"shipRecords.txt\");\n if(myfile.is_open())\n {\n while (!myfile.eof())\n {\n getline (myfile, line);\n addInfo(line);\n }\n myfile.close();\n }\n }\naddInfo(string line)\n {}\ndisplayOne(int serialNum)\n {}\ndisplayAll()\n {}\nint main()\n{\n HashMgr hm;\n hm.displayAll();\n hm.displayOne(1009);\n hm.displayOne(1010);\n hm.displayOne(1019);\n hm.displayOne(1029);\n hm.displayOne(1039);\n hm.displayOne(1014);\n hm.displayOne(1008); /// Prompt a message to that the record does not exist\n hm.deleteOne(1009);\n hm.deleteOne(1039);\n hm.displayAll();\n return 0;\n}\n/*\nHere is the txt.file\n 1009 1 \"Royal Queen\" 2015 160\n 1010 2 \"Carnival\" 2016 1600\n 1019 1 \"Ocean King\" 2013 110\n 1029 2 \"Royal Prince\" 2012 2000\n 1039 2 \"Royal Princess\" 2010 2100\n 1014 2 \"Royal Caribbean\" 2016 1600\n*/"

"Is this TOC scenario possible using c# and iTextSharp?",
"I've just downloaded iTextSharp and before I put a lot of effort into this I'd like to know if this scenario is possible with it. We have a client that is insisting that their SSRS report PDFs contain a table of contents, preferably with page numbers. The various components of these reports have highly variable lengths so we can't hard code actual page numbers. As you all probably know, there is no direct way to create a Table of Contents in SSRS. (We've even had a special session with the Microsoft rep about this.)\n\nWhat I would like to do is as follows: \n\n\nMark the target locations in the SSRS report by setting their\nDocumentMapLabel property. \nGenerate the pdf in the usual fashion, either from the report server \nor a ReportViewer control. (This will be in c#.)\nOpen the pdf in my hypothetical code.\nInsert a blank page at or near the front.\nScan the pdf for DocumentMapLabels (and, ideally, detect which page\nthey're on.)\nPopulate the blank page with links to the various sections.\n\n\nIs this possible?"

"WooCommerce custom plugin: Check for customer completed orders issue",
"I'm trying to write a simple plugin that would show new or returning customer information and the number of completed orders from the user. To do this, I created a folder called returning-customers.php and file with the same name. In this file, I wrote the next code:\n/*\n * Plugin Name: Kasha returning customers\n * Description: Displays information returning customer or new, and also displays the number of completed orders\n * Version: 1.0.0\n * Author: Me\n * License: GPLv2 or later\n */\n\n\nadd_filter( 'woocommerce_admin_order_data_after_order_details', 'render_customer_is_new_field' );\n\nfunction render_customer_is_new_field($order)\n{\n\n $args = array(\n 'status' => 'completed',\n 'return' => 'ids',\n );\n \n if ( $order->get_user_id() !== 0 ) {\n $args['customer_id'] = $order->get_customer_id();\n } else {\n $args['customer'] = $order->get_billing_email();\n }\n \n $customer_has_existing_orders = wc_get_orders( $args );\n\n $orders_count = count($customer_has_existing_orders);\n\n $markData = ( (int)count($customer_has_existing_orders) >= 2 )\n ? array('status-processing', 'Returning customer')\n : array('status-on-hold', 'New Customer');\n\n\n echo '\n <p class="kasha-customer-counter" style="float: left">\n <mark class="order-status '. $markData[0] .'">\n <span>'. $markData[1] .' <strong style="color:#ff0000;font-weight: 900;"> '. $orders_count .'</strong></span>\n </mark>\n </p>\n ';\n}\n\nBut this code does not work correctly. I always see that the customer has returned and all his orders are considered. However, the mark that the user is returning customer should be placed only after two orders with the status completed and only orders with the status completed should be considered. Now it looks like the wc_get_orders function is not working. When I write: var_dump(wc_get_orders()) I see NULL."

Compiler says:\n\n\"std::vector<Screen,std::allocator<_Ty>>::vector(std::initializer_list<Screen>,const std::allocator<_Ty> &)\": \nневозможно преобразовать аргумент 1 из \"Screen\" в \"const std::allocator<_Ty> &\" \nd:\\users\\family\\documents\\visual studio 2013\\projects\\consoleapplication\\screen\\screen.h\n\n\nBut the fact is such list initialization runs properly in two of my tryes outside the class (see main.cpp). I thought it was because of private modifier, but public didn't help very.\nSo could you suggest me, please, where the real problem is? Thanks!\n\nUPD I use MS VS Expess 2013 and CTP 2013 VC++ compiler."
