"How to calculate and display percentages from a binary dataframe",
"I am trying to create a table, where I calculate the percentages of applicants in different stages of a recruitment process. I have a dataframe that looks like this: \n\n# A tibble: 6 x 3\n CandidateType Step Amount\n <fctr> <chr> <dbl>\n1 External Hiring 304\n2 Internal Hiring 164\n3 External Interview 950\n4 Internal Interview 512\n5 External Application 8726\n6 Internal Application 828\n\n\nI need to add a column that calculates the percentages of applications that result in an interview, and the percentages of applications that ends up as hirings for each Group (internal and external applicants). It should look something like this:\n\n# A tibble: 6 x 3\n CandidateType Step Amount Pct\n <fctr> <chr> <dbl> <chr>\n1 External Hiring 304 3.48 %\n2 Internal Hiring 164 19.81 %\n3 External Interview 950 10.89 %\n4 Internal Interview 512 61.84 %\n5 External Application 8726 100.00 %\n6 Internal Application 828 100.00 %\n\n\nI've tried solving the problem using the following code, but with no luck:\n\nrecruitmentDFinternal <- recruitmentDF %>% \n filter(CandidateType == \"Internal\") %>% \n percent((Amount) / Amount[3])\n\n\nThe idea here was to use the percent function from the scales package, and create two separate data frames from each type of candidate, to ultimately do a bind_rows to piece them back together, but I had no luck getting the percent function to work. Does anyone have a solution for this problem? I need the Pct column to contain a %-symbol at the end of the percentage."

"Installing Win10 SDK (any version) hangs every time",
"I'm trying to install the Win10 SDK (any version - logs below are from 17763) for use in Visual Studio 2019. Every time I try, the install hangs. I finally have to go into Task Manager and kill off several processes. There are usually three for winsdksetup.exe and one Windows Installer. \n\nI've tried installing from the Visual Studio Installer, and also from the standalone SDK installer. They all hang, even the full ISO download of the SDK. Installing it standalone (outside Visual Studio), it gets as far as \"Updating Settings\" (around 45%) and then just sits there. I've left it for hours. I go in and find the same dead processes.\n\nThe logs, of course, are massive. A few relevant bits I've found are messages such as:\n\nMSI (s) (84:D8) [11:40:21:462]: Warning: Local cached package 'C:\\Windows\\Installer\\75742b.msi' is missing.\nMSI (s) (84:D8) [11:40:21:463]: SOURCEMGMT: Source is invalid due to missing/inaccessible package.\nMSI (s) (84:58) [11:43:33:684]: Product: Kits Configuration Installer -- Error 1714. The older version of Kits Configuration Installer cannot be removed. Contact your technical support group. System Error 1612.\n\n\nIt seems like something is missing or broken in my system... does anyone know what it could be, or how to fix this?"

"Alternative to Eclipse's Abstract Syntax Tree parser for code manipulation",
"Background\n\nI am writing a program that will do some bulk renaming of members and functions in a directory of java source code to de-obfuscate the code based on a look-up table .csv file passed in to the program. \n\nWhat this is for is the source code I have was written against a obfuscated jar. I have a de-obfuscated version of the jar that was run through a customized version RetroGaurd and I would like to parse the mapping file that was passed in to RetroGaurd to de-obfuscate the function calls my source code makes in to the jar. If I just compile my code and run it through RetroGaurd too when I decompile I loose all of my nice commenting and formatting (unless there is a option on RetroGaurd that I missed).\n\n\n\nProblem\n\nI found the Abstract Syntax Tree parser built in to Eclipse and it looks perfect for my uses, however I am not planning on writing my program as a plugin for Eclipse, this is going to be a stand alone jar that can be run on any machine.\n\nMy main concern is as I write my code I am getting a lot of dependencies on internal jars that Eclipse uses. I know that if I conform to the EPL for the library jars I will have no issues distributing it, but I am concerned about this project getting bigger and bigger as I write it as more and more jars from Eclipse's SDK are required.\n\nAre there any other projects out there that would give me the ability to parse Java source code to do find and replace reliably like AST will allow me to, or is there a way to use RetroGaurd (or a program like it) to run the same de-obfuscation but keep my comments and functions the same without needing to run the de-obfuscated program though a de-compiler afterwards?"

"Connecting Sails Socket IO to Sails server running in consul",
"There's this μService architecture running as the backend, with a consul instance managing all the services. There's a particular server, A made with Sails, and with some relevant socket logic I'd like to use from another service B using sails.io.\n\nEach service is running in its own Docker container, but they all connect to the same network.\n\nSo, when developing, I run the A container locally and simulate service B with a node script, with the logic showed here. The service URL is quite simple given that I'm just running the container with an open port, so the URL sails.io uses to connect is localhost:PORT. Everything here well.\n\nThe problem comes when service A is run in the μService architecture. Each service runs in its own URL, for example backend.com/api/SERVICE_NAME, acting like a namespace, with every route under the namespace actually hitting the SERVICE_NAME service. So now sails.io has issues connecting to service A, I presume, because of the change in route.\n\nThes are all the variations I've tried given const io = sailsIOClient(socketIOClient);\n\nio.sails.url = 'http://backend.com/api/SERVICE_NAME';\n\n\nthen \n\nio.sails.url = 'http://backend.com';\nio.sails.path = '/api/SERVICE_NAME'\n\n\nthen\n\nio.sails.url = 'http://backend.com';\nio.sails.path = '/api/SERVICE_NAME/socket.io/'\n\n\nThen I stumbled with this that refers to a path argument on the connect function of socket.io (here's the specific). I tried with that, setting io.sails.autoConnect to false and calling io.sails.connect() but I'm not being able to connect to the Sails app.\n\n Socket is trying to reconnect to Sails...\n_-|>_- (attempt #293)\n\n\nI'm fairly certain the issue is that the client io can't reach the correct route to find the Sails app because of the architecture is set up.\n\nHas someone dealt with a similar scenario? Suggestions are greatly appreciated."

"Esri JS Api 4.18 requires ncp copy of node_modles for BUILD and START. what and were do I need to copy assets for working in storybook.js",
"To use the ES modules for esri JS Api 4.18 requires ncp copy of node_modules for BUILD and START. what and where do I need to copy assets for working in storybook.js?\nCopy assets\nYou will need to copy the API’s assets, which includes styles, images, fonts, and localization files, from the @arcgis/core/assets folder to your build folder. A simple way to accomplish this is to configure an NPM script that runs during your build process. For example, use npm to install ncp and configure a script in package.json to copy the folder. Here’s a React example:\n// package.json\n\n {\n "script": {\n "start": "npm run copy && react-scripts start",\n "build": "npm run copy && react-scripts build",\n "copy": "ncp ./node_modules/@arcgis/core/assets ./public/assets"\n }\n }\n\n\nhttps://developers.arcgis.com/javascript/latest/es-modules/"

"How should PLI packets be used in WebRTC video recording",
"We are using the licode MCU to streaming video from Google Chrome to the server and record it. The tricky part here is that there is only one Chrome browser involved so the server-side code has to handle sending feedback to the client.\n\nWe added server-side code to send REMB (bandwidth) packets every 5 seconds to the client. This causes the client to increase bitrate so that the video quality is good.\n\nWe did something similar with PLI packets to attempt to improve video quality. The recorded video had blocky artifacts and didn't look good. The current code sends a PLI every 0.8 seconds which causes the client to send a keyframe (full frame of video). This fixes the poor video quality because it forces a keyframe but when there is packet loss (wifi network) it quickly gets bad again.\n\nMy question is how should these PLI packets be used?\n\nI think PLI means:\n\nPLI - Picture Loss Indication"

The time series variable is sent to the method and the method should process it and send it back. When the debugger is on 2, the method is not executed.

I want to select the range B3:AG120. \n\nThe code I have written to do this in VBA is not working. It correctly stops at B120 (in this example), however, once it reaches the non-continuous data in columns C-AG, it freaks out and selects rows past 120. I am not positive why this code is not working, any help is much appreciated!\n\nFor the record, there are formulas in nearly every cell in the sheet. Only some formula populate the cell with data, however. I want to select every cell regardless of if it is populated with data IF IT IS IN MY RANGE. Otherwise, I do not want to select it. For example, past B120 there are empty cells with formulas in them. I do not want to include those in my range. But if there is an empty cell in D40 (in between B3 and AG120) I do want to include that in the selection. \n\nDim LR As Long, cell As Range, rng As Range\nWith Sheets(\"Sortable(2)\")\n LR = .Range(\"B\" & Rows.Count).End(xlUp).Row\n For Each cell In .Range(\"B3:B\" & LR)\n If cell.Value <> \"\" Then\n If rng Is Nothing Then\n Set rng = cell\n Else\n Set rng = Union(rng, cell)\n End If\n End If\n Next cell\n rng.Select\nEnd With"

"PHP: Session files contain no data",

For one, I've noticed that most of the tutorials simply say \"Here's the code, go use it.\" and not so much \"This is how it works.\" Additionally, all of the issues/answers I find seem to be about information being lost on refresh or after switching pages and none of these apply to me.\n\nThe data in $_SESSION is being stored/loaded no matter which page I view. My issue is, when I view the session files on the server, there is no data in them. Additionally, when I destroy a session or unset the variables the information is still stored and the next time $_SESSION is accessed the old information is retrieved.\n\nTo troubleshoot the behavior of sessions on my server I created an extremely simple script:\n\n<?php\n// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less\nif (!isset($_SESSION['count'])) {\n $_SESSION['count'] = 0;\n} else {\n $_SESSION['count']++;\n}\n\necho $_SESSION['count'];\n?>\n\n\nThis is ALL of the code on the page (viewable here: ).

"IBM Watson Assistant: How to set a context variable from option response?",
"I couldn't figure out a problem with IBM Watson Assistant. I've chosen to use an Option type as response. That way, I can see a list on my chatbot where each item is clickable and has an associated value.\nWhen a user clicks one of the options, the associated user input value is sent to the assistant. How can I give this value to a context variable? Is it possible?"

"Will I be able to use C# 4 as my scripting language?",
"In one of my C# application I use IronPython as a script language.

"How to use the [HandleError] attribute in ASP.NET MVC?",
"I've got some custom error handling in my ASP.NET MVC site -> seems to be working fine.\n\nI have an Error Controller, like this :-\n\n/Controller/ErrorController.cs\n\n[AcceptVerbs(HttpVerbs.Get)]\npublic ActionResult Unknown()\n{\n Response.StatusCode = (int)HttpStatusCode.InternalServerError;\n return View(\"Error\");\n}\n\n[AcceptVerbs(HttpVerbs.Get)]\npublic ActionResult NotFound()\n{\n Response.StatusCode = (int)HttpStatusCode.NotFound;\n return View(\"Error\");\n}\n\n\n(i've also removed some other text, like the message to display, etc..)\n\nThe view is located like..\n\n/Views/Error/Error.aspx\n\n\nNow, i'm not sure how I can 'call' the Unknown method (above) when an error occurs. I thought I could use the [HandleError] attribute, but this only allows me to specify a View (and I'm don't think i'm doing that properly, cause the error url is really weird)."
