"Magento - Show product attributes on Order confirmation email",
"I need help with the following:\n\nIn Magento I have created a configurable product and assigned some simple products to it. They have an individual attribute set with individual attributes that I have created.\n\nOn the order review page, the product name as well as the options are displayed - this is fine.\n\nOn the order confirmation email, only the product's name and the SKU of the associated/ordered product is displayed. I need to display the atttributes that belong to my product as well (the attributes, that I have created to describe that specific product, like length, width, etc.).\n\nAny help is appreciated!\nThanks!"

"NPM not caring about duplicate dependencies. Did this change?",
"Unlike other package managers, npm installs a tree of dependencies. Each package has its node_modules folder, and can contain the same dependency in the same or different version. At least this was the case in 2016, described here and here.\nNow when i open node_modules, i see many more sub-folders than before and that's strange especially when i installed only one package in my project (umi-test). I guess those are all dependencies of that package, installed horizontally. So it seems NPM installs only one version of each package and no duplicates anymore.\nWhat's the truth?"

"Limit RewriteRule in htaccess file",
"i got a site php based with some rules in the .htaccess file to get rid of file extentions in the url adress bar. Basically it takes http://netbureau.com.br/en/about.php/ and turns it into http://netbureau.com.br/en/about.\nHere are the lines in the htaccess file:\nRewriteEngine on\nRewriteCond %{REQUEST_FILENAME} !-d\nRewriteCond %{REQUEST_FILENAME}\\.php -f\nRewriteRule ^(.*)$ $1.php\n\nThe problem comes when i try to access the rss feed of the blog at http://netbureau.com.br/blog/?feed=rss2 and when i try to set custom permalinks for the blog at http://netbureau.com.br/blog. It gets messed up by the htaccess file.\nSo is there any way to disallow the RewriteRule for the /blog folder so that i can get back my rss link and set custom permalinks in the blog?\nI know it's at the same time Wordpress related but it feels more connected to the htaccess file than Wp.\nThanks in advance.\nEDIT #1:\nI've set up the wordpress permalinks to the default structure which goes like this: http://netbureau.com.br/blog/?p=123 This made my rss link back for good.\nThe remaining problem is that Wordpress gives me its own rewriterule which is:\nRewriteEngine On\nRewriteBase /blog/\nRewriteRule ^index\\.php$ - [L]\nRewriteCond %{REQUEST_FILENAME} !-f\nRewriteCond %{REQUEST_FILENAME} !-d\nRewriteRule . /blog/index.php [L] \n\nIs there a way to to still use the first rule to apply to the whole site except the /blo/ folder and apply the WP rule only to the /blog/ folder?\nI've tried different combinations but without luck so far. I could only have the site without the custom links for the blog or the custom blog links and a 404 on the pages of the site."

"Setting TIME_WAIT TCP",
"We're trying to tune an application that accepts messages via TCP and also uses TCP for some of its internal messaging. While load testing, we noticed that response time degrades significantly (and then stops altogether) as more simultaneous requests are made to the system. During this time, we see a lot of TCP connections in TIME_WAIT status and someone suggested lowering the TIME_WAIT environment variable from it's default 60 seconds to 30.\n\nFrom what I understand, the TIME_WAIT setting essentially sets the time a TCP resource is made available to the system again after the connection is closed.\n\nI'm not a \"network guy\" and know very little about these things. I need a lot of what's in that linked post, but \"dumbed down\" a little.\n\n\nI think I understand why the TIME_WAIT value can't be set to 0, but can it safely be set to 5? What about 10? What determines a \"safe\" setting for this value?\nWhy is the default for this value 60? I'm guessing that people a lot smarter than me had good reason for selecting this as a reasonable default.\nWhat else should I know about the potential risks and benefits of overriding this value?"

"Struggling to translate jQuery JSONP query to a Node.JS query using http.request",
"Long-time(well, 3 months) reader, first-time poster. I have a client-side jquery AJAX request of some JSONP data which I am trying to switch into a http.request, so I can use it server-side on a Node.js server.\n\nThe jQuery works easily enough: JSfiddle here http://jsfiddle.net/gk0uttdu/ , code here:\n\n $.ajax({\n type: 'GET',\n url: 'http://www.mysupermarket.co.uk/Api.aspx?Command={\"Output\":\"JSONP\",\"Commands\":[{\"Name\":\"Basket\",\"Params\":{\"BrandStores\":[\"780\"],\"ProductPrices\":{\"920\":[\"ASDA\",\"Ocado\",\"Sainsburys\",\"Tesco\",\"Waitrose\"],\"016555\":[\"ASDA\",\"Sainsburys\",\"Tesco\",\"Waitrose\"]},\"TrolleyItems\":[\"920\",\"52200\",\"1017\"],\"TrolleyLinks\":[\"780\"]}}]}&banner=34',\n dataType: 'jsonp',\n success: function(json) {\n alert(JSON.stringify(json)); \n }\n});\n\n\nHowever, when I try to rewrite this request using Node's http module as below, it fails with a 403.

"The Mystery of an Image",
"So I'm developing a Model View Controller (MVC) project. Due to the size and complexity, I'm trying to ensure organization. I've managed to stumble on a unique quandary, one that has left me quite stumped. My issue is drawn from a Jquery Rotator that I'm integrating into my site.\n\nMy Solution Explorer:\n\n\nContent : This particular folder contains three direct sub-folders Images, Scripts, and Stylesheets.\n\n\nThose three sub-folders contain more specific and honed in details, an example would be the Scripts contains another folder called Rotator for this jQuery implementation.\n\nSo the dilemma occurs inside the View.\n\nAn example within this View:\n\n<div class = \"banner-style\">\n <div id = \"Infinite-Banner\">\n <div class = \"banner-container\">\n <div class = \"slides\">\n <img src = \"~/Content/Images/Banner/Slides/One.jpg\">\n <img src = \"~/Content/Images/Banner/Slides/Two.jpg\">\n </div>\n </div>\n </div>\n</div>\n\n\nSo within this structure it doesn't appear to load the Images. Though it is properly mapped to the directory. But if you use the same structure above but change the img portion to:\n\n<div class = \"slide-one\" />\n<div class = \"slide-two\" />\n\n\nThen in a the correlating Stylesheet, simply define a background: url(~/Content/Images/Banner/Slides/One.jpg); for the slide-one Element it magically appears. \n\nSo this makes me believe that it is due to nesting. But doesn't quite make sense, as this will force me to build an inner element between the div slides so that I can generate the proper affects.\n\nThe other idea would be to create a model that maps all the relational image data; but that seems like an awful lot of work.\n\nIs this a limitation or an issue specific to my machine? What would be the best work around to such an issue? Is this indeed due to the structure I've taken to my folders?"

"Performant calculation of datetime diffs in days",
"I have a Django model that contains a unique record with a date . I'm currently counting records into ranges of days, e.g. X Number have already passed todays date, X will happen within the next 10 days, X will happen within the next 30 days.\nThe code below is what I am currently using, it pulls all values back from an records.objects.all() query against the model and then loops through each object to calculate the datetime delta and increment the relevant counter.\n\nfor x in records:\n if x.date is None:\n missingValue += 1\n else:\n delta = x.date - date.today()\n if delta.days < 0:\n passed += 1\n if delta.days < 10:\n tenDays += 1\n if delta.days < 30:\n thirtyDays += 1\n\n\nFor around 50,000 records this takes about 5-6 seconds which is longer than I would like, I'm trying to reduce this as the number of records is likely to increase.\nThe question is really around the performant calculation of datetime diffs and grouping the resultant number of days as if there is a better method through a Django Query or other method I've not been able to find I'm open to trying it.\n\nI've explored the use of DateAdd in a raw SQL but it would appear to need me to query the database for each date range and would still lead to me needing to loop through the results."

"ASP .NET MVC Form fields Validation (without model)",
"I am looking for a way to validate two fields on ASP View page. I am aware that usual way of validating form fields is to have some @model ViewModel object included on a page, where the properties of this model object would be annotated with proper annotations needed for validation. For example, annotations can be like this:\n\n[Required(ErrorMessage = \"Please add the message\")]\n[Display(Name = \"Message\")]\n\n\nBut, in my case, there is no model included on a page, and controller action that is being called from the form receives plane strings as method arguments.\nThis is form code:\n\n@using (Html.BeginForm(\"InsertRssFeed\", \"Rss\", FormMethod.Post, new { @id = \"insertForm\", @name = \"insertForm\" }))\n{\n<!-- inside this div goes entire form for adding rssFeed, or for editing it -->\n ...\n <div class=\"form-group\">\n <label class=\"col-sm-2 control-label\"> Name:</label>\n <div class=\"col-sm-10\">\n <div class=\"controls\">\n @Html.Editor(\"Name\", new { htmlAttributes = new { @class = \"form-control\", @id = \"add_rssFeed_name\" } })\n </div>\n </div>\n </div>\n\n <div class=\"form-group\">\n <label class=\"col-sm-2 control-label\"> URL:</label>\n <div class=\"col-sm-10\">\n <div class=\"controls\">\n @Html.Editor(\"Url\", new { htmlAttributes = new { @class = \"form-control\", @id = \"add_rssFeed_Url\" } })\n </div>\n </div>\n </div>\n\n </div>\n </div>\n <!-- ok and cancel buttons. they use two css classes. button-styleCancel is grey button and button-styleOK is normal orange button -->\n <div class=\"modal-footer\">\n <button type=\"button\" class=\"button-styleCancel\" data-dismiss=\"modal\">Close</button>\n <button type=\"submit\" class=\"button-styleOK\" id=\"submitRssFeed\">Save RSS Feed</button>\n </div>\n}\n\n\nYou can see that form is sending two text fields (Name and Url) to the RssController action method, that accepts these two string parameters:\n\n[HttpPost]\npublic ActionResult InsertRssFeed(string Name, string Url)\n{\n\n if (!String.IsNullOrEmpty(Name.Trim()) & !String.IsNullOrEmpty(Url.Trim()))\n {\n var rssFeed = new RssFeed();\n rssFeed.Name = Name;\n rssFeed.Url = Url;\n\n using (AuthenticationManager authenticationManager = new AuthenticationManager(User))\n {\n string userSid = authenticationManager.GetUserClaim(SystemClaims.ClaimTypes.PrimarySid);\n string userUPN = authenticationManager.GetUserClaim(SystemClaims.ClaimTypes.Upn);\n\n rssFeedService.CreateRssFeed(rssFeed);\n }\n }\n\n return RedirectToAction(\"ReadAllRssFeeds\", \"Rss\");\n}\n\n\nIf the page would have model, validation would be done with @Html.ValidationSummary method, but as I said I am not using modelview object on a page. \nIs there a way to achieve this kind of validation without using ModelView object, and how to do that?

"How can I create a re-usable piece of markup in Jade",
"What I'm trying to accomplish.\n\nWhat I'm trying to do is actually really simple and the Jade template engine should be able to help me out quite a bit with it, but I'm running into some snags.\n\nI'm building a site that uses a lot of semi-transparent elements like the one in this jsFiddle: http://jsfiddle.net/Chevex/UfKnM/\nIn order to make the container background be semi-transparent but keep the text opaque this involves 3 elements:\n\n\nA container DIV with position: relative\nA child DIV with position: absolute, a background color, height/width set to 100%, and its opacity set to the desired level.\nAnother child DIV for the content with no special positioning.\n\n\nIt's pretty simple and I use it fairly effectively on CodeTunnel.com.\n\nHow I want to simplify it.\n\nI'm re-writing CodeTunnel.com in node.js and the Jade template engine seems like it could greatly simplify this piece of markup that I re-use over and over again. Jade mixins look promising so here's what I did:\n\n\nI defined a mixin so I could just use it wherever I need it.\n\nmixin container\n .container(id=attributes.id) // attributes is an implicit argument that contains any attributes passed in.\n .translucentFrame\n .contentFrame\n block // block is an implicit argument that contains all content from the block passed into the mixin.\n\nUse the mixin, passing in a block of content:\n\n+container#myContainer\n h1 Some test content\n\n\nGenerates:\n\n<div id=\"myContainer\" class=\"container\">\n <div class=\"translucentFrame\"></div>\n <div class=\"contentFrame\">\n <h1>Some test content</h1>\n </div>\n</div>\n\n\n\nSo far everything works great! There is just one problem. I want to use this mixin in a layout.jade template and I want the child template to be able to use block inheritance. My layout.jade file looks like this:\n\ndoctype 5\nmixin container\n .container(id=attributes.id)\n .translucentFrame\n .contentFrame\n block\nhtml\n head\n title Container mixin text\n body\n +container#bodyContent\n block bodyContent\n\n\nThen in another jade file (index.jade) I extend layout.jade:\n\nextends layout\n\nblock bodyContent\n h1 Some test Content\n\n\nEverything looks to be in order but the jade parser fails:\n\n\n\nI assume it has something to do with the block keyword conflicting. Inside a mixin block is an implicit argument containing the block passed into the mixin, but when extending a jade template block is a keyword that identifies a block of markup that is to be substituted in the equivalent block in the parent template.\n\nIf I replace the block bodyContent that I'm passing into the mixin with any other markup then everything works fine. It's only when I try to pass in a block definition that it gets upset.\n\nAny ideas?"

"Python: Generating a big uniform permutation cheaply",

For example, say that I want a permutation on range(10**9). I want the permutation to be uniform (i.e. I want the numbers to be all over the place without any seeming structure.) I want to have a function available to get the nth item in the permutation for each n, and I want to have another function available to get the index of every number in the permutation. \n\nAnd the big, final condition is this: I want to do all of that without having to store all the items of the permutation. (Which can be a huge amount of space.) I want each item to be accessible, but I don't want to store all the items, like range in Python 3.\n\nIs this possible?"

"Compute a running ratio of two totals",
"I have a PostgreSQL 9.4.1 database (Retrosheet data) with a table events containing one row per baseball play. I want to a compute a running batting average for a given player: the formula is (total number of hits so far)/(total number of valid at-bats so far).\n\nI can use window functions to get a running total of hits for David Ortiz, whose player code is ortid001, using the following query:\n\nSELECT count(*) OVER (ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) \nFROM events WHERE bat_id='ortid001' AND (event_cd='20' OR event_cd='21' \nOR event_cd='22' OR event_cd='23');\n\n\n(The clause involving event_cd just identifies which rows are considered hits.)\n\nUsing the same technique, I can get a running total of at-bats (the event_cd clause rejects every row that doesn't count as an at-bat. note that the hits selected above are a subset of at-bats):\n\nSELECT count(*) OVER (ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) \nFROM events WHERE bat_id='ortid001' AND (event_cd != '11' AND \nevent_cd!='14' AND event_cd!='15' AND event_cd!='16' AND \nevent_cd!='17');\n\n\nHow can I combine these? Ideally, for each row describing a play with bat_id='some_player_id', I would compute two functions: the count of all preceding rows describing an at-bat, and the count of all preceding rows describing hits.

It's a heisenbug, so I haven't figured out exactly what's causing it.\n\nI've done the search and found that there was a known problem with an older version of python, but I'm using 2.7.10 (in a virtualenv, in case that matters)\n\nI'm using pandas (0.18.0) , scipy(0.17.0) and numpy (1.11.0), in case the problem might be in there..."

"Optimisation of view hierarchy in iOS",
"Consider this view hierarchy: \n\n +----------------------------+ \n |A |\n |+--------+ +------------+ |\n ||B | |C | |\n || | |+----------+| |\n |+--------+ ||D || |\n | |+----------+| |\n | +------------+ |\n +----------------------------+\n\n\nIf there is an event on the view \"D\", the systems hit test returns the view 'A'. Then, it calls pointInside:withEvent: on B which returns NO. It recursively goes down in the hierarchy of 'C' (because the pointInside:withEvent: returned YES) to come to a conclusion that the hit event actually happened in 'B'. \n\nNow, it looks like the pointinside:withEvent call on the view 'B' is a waste of CPU. What if the view is very complex and if the system futilely calls this on views, doesn't it adversely affect the system performance? \n\nIn this light, how can we, as developers, construct our views to increase the response time to events?"

"Is sizeof(T) == sizeof(int)?",
"I've been poring over the draft standard and can't seem to find what I'm looking for.\n\nIf I have a standard-layout type\n\nstruct T {\n unsigned handle;\n};\n\n\nThen I know that reinterpret_cast<unsigned*>(&t) == &t.handle for some T t; \n\nThe goal is to create some vector<T> v and pass &v[0] to a C function that expects a pointer to an array of unsigned integers.\n\nSo, does the standard define sizeof(T) == sizeof(unsigned) and does that imply that an array of T would have the same layout as an array of unsigned?\n\nWhile this question addresses a very similar topic, I'm asking about the specific case where both the data member and the class are standard layout, and the data member is a fundamental type.\n\nI've read some paragraphs that seem to hint that maybe it might be true, but nothing that hits the nail on the head. For example:\n\n§ 9.2.17\n\n\n Two standard-layout struct (Clause 9) types are layout-compatible if\n they have the same number of non-static data members and corresponding\n non-static data members (in declaration order) have layout-compatible\n types\n\n\nThis isn't quite what I'm looking for, I don't think."

"How to design \"ordering\" of objects with Core Data",
"I have a Bullet object and a List object. A List has many bullets and a Bullet can belong to many Lists. \n\nBut I need to guarantee ordering of Bullet objects. For example, a List object should always have #1 Bullet A #2 Bullet B and #3 Bullet C in that order. Another List (List B) might have those same bullets, but in a different order, #1 Bullet B, #2 Bullet C and #3 Bullet A. \n\nNSSet doesn't store ordering, and Core Data doesn't allow arrays. \n\nWhat should I do? Can I do something with properties here? \n\nEdits: After listening to the comments below, I realized that it's a \"Many to Many\" relationship between lists and bullets ... For example, a Bullet (name: \"Egg\") can appear in the List (name: \"Dairy\") and the List (name: \"Food\")."
