[ "Using Extensions: Weighing The Pros vs Cons", "Recently I asked a question about how to clean up what I considered ugly code. One recommendation was to create an Extension Method that would perform the desired function and return back what I wanted. My first thought was 'Great! How cool are Extensions...' but after a little more thinking I am starting to have second thoughts about using Extensions...\n\nMy main concern is that it seems like Extensions are a custom 'shortcut' that can make it hard for other developers to follow. I understand using an Extension can help make the code syntax easier to read, but what about following the voice behind the curtain? \n\nTake for example my previous questions code snippet:\n\nif (entry.Properties[\"something\"].Value != null)\n attribs.something = entry.Properties[\"something\"].Value.ToString();\n\n\nNow replace it with an Extension:\n\npublic static class ObjectExtensions\n{\n public static string NullSafeToString(this object obj)\n {\n return obj != null ? obj.ToString() : String.Empty;\n }\n}\n\n\nand call using the syntax:\n\nattribs.something = entry.Properties[\"something\"].Value.NullSafeToString();\n\n\nDefinetely a handy way to go, but is it really worth the overhead of another class object? And what happens if someone wants to reuse my code snippet but doesn't understand Extension? I could have just as easily used the syntax with the same result:\n\nattribs.something = (entry.Properties[\"something\"].Value ?? string.Empty).ToString()\n\n\nSo I did a little digging and found a couple of articles that talked about the pros/cons of using Extensions. For those inclined have a look at the following links:\n\nMSDN: Extension Methods\n\nExtension Methods Best Practice\n\nExtension Methods\n\nI can't really decide which is the better way to go. Custom Extensions that do what I want them to do or more displayed code to accomplish the same task? I would be really interested in learning what 'real' developers think about this topic..." ]

[ "Handling timers for many users in Nodejs", "I'm building a web app in Node/Express such that users can set a timer so that a certain task gets executed or repeated. My question is how can I set timer for many users with an event triggered after deadline. I don't want to handle this on the client side beacuse users can close the browser. A good example of this is services such as pingdom.com that allow you to set timer and send a ping every X minutes to your server. How can this be acheived?\nI hope I don't get many negatives for asking this and I'm also not asking you guys to write me the code. I simply want to know a robust strategy to solve this problem. \nHere is what I thought about:\n\n\nSave the endtime in db and using a cron job check every second to see if the time is up (This is not really good in my opinion since the query and all calculations might take more than 1 second)\nSomehow assign a variable to setInterval and store them in a global list" ]

[ "Firefox 57 loads http request twice", "TL;DR This appears to be a browser problem that is fixed in newer (58+) versions.\n\n\n\nI'm working on a Node.js/express-based web server and I'm running into a problem where my browser (Firefox 57.0.1 on Mac OS) loads a page twice. I've been googling for tons and tons of other answers and blog posts, but haven't found a solution yet.\n\nObviously, apart from the double network traffic, this is a problem in an application that performs database work under the hood.\n\nReproducing the problem\n\nHere's a simple script to replicate the issue:\n\n#!/usr/bin/env node\n\nconst express = require('express');\n\nconst app = express();\napp.disable('etag');\n\napp.listen(3000, () => console.log('\\n\\n\\n\\n\\nListening on port 3000!'));\n\napp.all('/', function (req, res, next) {\n rn=Math.random();\n console.log('\\n'+req.method+' '+req.url);\n console.log('rn='+rn);\n res.send('rn='+rn);\n next();\n});\n\n\nFor every request to /, the server generates a random number and returns it to the client. That way, I can see (using console.log()) how many requests are being made and which ones are being rendered in the browser.\n\nWhen I request http://localhost:3000/, I get the following output in my console:\n\nGET /\nrn=0.3196834037080407\n\nGET /\nrn=0.8270968825090677\n\n\nFull HTTP headers\n\nUsing Firefox' developer tools, I can see that two identical requests are being made. First request:\n\nAccept: text/html,application/xhtml+xm…plication/xml;q=0.9,*/*;q=0.8\nAccept-Encoding: gzip, deflate\nAccept-Language: en-US,sv-SE;q=0.5\nCache-Control: max-age=0\nConnection: keep-alive\nDNT: 1\nHost: localhost:3000\nUpgrade-Insecure-Requests: 1\nUser-Agent: Mozilla/5.0 (Macintosh; Intel …) Gecko/20100101 Firefox/57.0\n\n\nFirst response:\n\nConnection: keep-alive\nContent-Length: 21\nContent-Type: text/html; charset=utf-8\nDate: Mon, 18 Dec 2017 05:44:51 GMT\nX-Powered-By: Express\n\n\nSecond request:\n\nAccept: text/html,application/xhtml+xm…plication/xml;q=0.9,*/*;q=0.8\nAccept-Encoding: gzip, deflate\nAccept-Language: en-US,sv-SE;q=0.5\nCache-Control: no-cache\nConnection: keep-alive\nDNT: 1\nHost: localhost:3000\nPragma: no-cache\nUpgrade-Insecure-Requests: 1\nUser-Agent: Mozilla/5.0 (Macintosh; Intel …) Gecko/20100101 Firefox/57.0\n\n\nThe only difference between the first and the second requests are the Cache-Control and Pragma headers.\n\nSecond response:\n\nConnection: keep-alive\nContent-Length: 21\nContent-Type: text/html; charset=utf-8\nDate: Mon, 18 Dec 2017 05:44:51 GMT\nX-Powered-By: Express\n\n\nI can actually see Firefox render the first number and then immediately replace it with the second, as if it actually clicks the \"Reload\" button.\n\nIn the developer tools, on the \"Stack trace\" tab seems to confirm this. Here's the first request:\n\nloadURI/< chrome://global/content/browser-child.js:354:14\n_wrapURIChangeCall chrome://global/content/browser-child.js:308:7\nloadURI chrome://global/content/browser-child.js:353:5\nreceiveMessage chrome://global/content/browser-child.js:288:9\n\n\n.. and the second request:\n\nreload chrome://global/content/browser-child.js:366:5\nreceiveMessage chrome://global/content/browser-child.js:297:9\n\n\nOther things I've checked\n\n\nI've disabled Adblock Plus for localhost. There are no other add-ons installed in the browser.\nNo other browser I've tried exhibits the same behaviour: Safari on MacOS, Chrome 63 on Windows, Edge, Internet Explorer 11.\nThere's no cross-origin stuff going on here, it's a simple one-page request.\nNo javascript involed.\nNo images, scripts or iframes with empty hrefs.\nBoth responses are HTTP/200, both requests are GET (i.e. no HEAD thing happening).\n\n\nAny pointers would be greatly appreciated." ]

[ "Ajax events in jQuery - firing an event on form submission using Rails", "I have a page with multiple forms on it. These forms are using a data attribute data-remote=\"true\n so that the Rails jquery-ui-rails.js automatically adds events to submit these forms via javascript.\n\nWhen a user submits any of these forms I would like to add a class so I can style it as needed. As Rails is automatically adding the ajax handlers to submit the form I can't just add this class at the point the handlers are added - I need to manually add code for this myself (I think).\n\nThe following code was my first attempt - this attaches okay, but as ajaxStart is a global event it triggers it simultaneously for every form on the page.\n\n$('form').ajaxStart(function(e) {\n console.log(\"element is \" + ($(e).attr('id')));\n return $(e).addClass('submitting');\n})\n\n\nI have also tried beforeSend as according to http://docs.jquery.com/Ajax_Events this is a local event and seems to be the only relevant one: \n\n$('form').beforeSend(function(e) {\n console.log(\"element is \" + ($(e).attr('id')));\n return $(e).addClass('submitting');\n})\n\n\nHowever, this raises the error:\n\nUncaught TypeError: Object [object Object] has no method 'beforeSend' \n\n\nHow can I attach this event to all of the forms on my page so that it fires once per ajax submission, and only for the current form that is being submitted?" ]

[ "Transferring data between layers of an application", "If I have a C# application with a 5 layer architecture, much like what is presented here http://msdn.microsoft.com/en-us/library/ee658109.aspx, and I take the strict interaction approach of allowing a layer to only interact with the layer below, I am running into trouble when getting data in my Data layer and passing that data back up to my Business layer.\n\nFor example, if I have a business object called MyObject that is defined in my Business layer, but information needed to construct an object of type MyObject is retrieved from the database in the Data layer, my Business layer needs a reference to my Data layer in order to interact with the database. But, my Data layer then also needs a reference to the Business layer, since that is where the MyObject definition lives and the Data layer needs to construct an object of that type from the database results and give that data back to the Business layer. Now we have a circular dependency between the Business layer and the Data layer.\n\nI am wondering what the proper approach is to solve this problem.\n\nI have thought about using DTO objects defined in my Data layer to pass information back to the Business layer. This would work since the Business layer is able to interact with the Data layer, but not vice versa. It just seems like this might be an awful lot of duplicate code to basically mimic the business object definitions in the Data layer.\n\nI also thought about creating interfaces for all of my business objects and putting those interfaces into a separate project that both the Business layer and Data layer can interact with. That way, I can pass instances of the interface and the only common reference between the Business layer and Data layer is the project where the interfaces are defined. I don't see many implementations of this either.\n\nI am wondering what others have done to solve this problem." ]
