"Leaflet-geoman how to properly retrieve GeoJSON",

"What is the best practice flutter equivalent to react-navigation's createBottomTabNavigator()?",
"I want to create tab navigation with a custom animated tab bar in Flutter which keeps state of current tab (scroll postion, forms etc) when tabs are switched. This could be done easily in react-native with react-navigation's createBottomTabNavigator(). Because I'm new to Flutter, I don't know the best approach to this.\nI can't use TabBar/TabView from material widgets because custom animations in TabBar don't seem possible. So far the only solution I've found is to use IndexedStack widget to store the pages and switch them with a separate tab bar.\nIs this the right/best approach? How will it work with hardware back on Android? I would be grateful if someone with more experience could advise on this."

".NET Socket Client performance seems to be capped per destination IP",
"I have an asynchronous console .NET socket client application that establishes dozens of connections to a remote socket server. \n\nIt's a stress test application so each connection sends as many messages as possible waiting for an acknowledgement from the remote server after each message gets sent.\n\nThe socket server has a public IP but I can also use the internal IP because it's in the same network.\n\nAs the number of connection increases the number of messages per minute goes down pretty bad and I've been trying to find out why. \n\nBut for some reason, the performance only seems to go down for the connections sharing the same destination IP. In other words, if I connect 100 users to the internal IP and 5 users to the external IP, the latter get top-notch performance while the former suffer. \n\nBut this makes no sense because all the communication is happening exactly between the same two machines (my desktop and the one-and-only server).\n\nThe amount of data being transferred doesn't seem that high for it to be some kind of network flooding. Honestly, it looks like some sort of artificial cap for the number of simultaneous sockets waiting for answers on a given destination IP. I've profiled my code and that's where it hangs, waiting for the remote server to answer. Is there a setting like that somewhere in the config files for .Net? \n\nUPDATE: there's just one NIC in the server, the external IP we use to reach it works via port forwarding.\n\nMore internal IPs were added to the server but they ended up competing with each other for resources i.e. only the external IP is behaving differently. This makes me suspect the bottleneck is on the server side, maybe some kind of load balancing per client IP (when we connect via external IP the client IP they receive would be different as well)"

"How to configure typescript debuging in VSCode with the service running from transpiled JS in the docker?",
"I'm working on the service written in typescript/node.js that is part of bigger mono-repository. The service itself depends on other shared node.js libraries in the same repo and the current build process doesn't allow for simple "npm ..." builds. You have to rebuild the whole repo (via make).\nI'm running the build inside docker container with the source code is mounted.\nI have opened the service directory itself in the VSCode, that's why devcontainer.json has such mounting point:\n{\n...\n "workspaceMount": "source=${localWorkspaceFolder}/../../..,target=/workspace,type=bind,consistency=cached",\n "workspaceFolder": "/workspace/src/services/SERVICE_NAME",\n...\n}\n\nWhen the docker container starts, it has directories:\n\n/workspace <-- source code\n/build <-- where make commands are run\n/install <-- destination for make install\n\nAfter running make install, the directory /install/sbin/SERVICE_NAME contains transpiled .js and .js.map files for the service.\nMap files seem to have a proper source set:\n{\n "version":3,\n "file":"index.js",\n "sourceRoot":"/workspace/src/services/SERVICE_NAME/",\n "sources":["index.ts"],\n "names":[],\n "mappings":";;AAAA;;;EA..."\n}\n\nThere is a launch configuration to run the service:\n{\n "version": "0.2.0",\n "configurations": [\n {\n "type": "node",\n "request": "launch",\n "name": "Run remote",\n "program": "/install/sbin/SERVICE_NAME/index.js",\n "args": [\n "--swaggerdir", "/workspace/src/services/SERVICE_NAME/",\n "--certdir", "/workspace/src/services/SERVICE_NAME/test/certs/"\n ],\n "env": {\n "FAKELDAP": "0"\n }\n }\n ]\n}\n\nService starts and debugger is attached, but the only way to set breakpoints is to find JS files in the "Loaded scripts" sidebar.\nI would like to be able to set breakpoints in the source typescript files. For that I tried setting sourceMap and playing with outFiles (for example, /install/sbin/SERVICE_NAME/**/*.js). I also tried using sourceMapPathOverrides, but nothing worked.\nI suspect that something fishy is going on based on logging output when the service starts. With the configuration above, console.log outputs points to:\n\n/install/sbin/SERVICE_NAME/workspace/src/services/SERVICE_NAME/file_one.ts (the correct location is workspace/src/services/SERVICE_NAME/file_one.ts)\n/install/sbin/SERVICE_NAME/file_two.ts (the correct location is workspace/src/services/SERVICE_NAME/controllers/file_two.ts)"

For the particular workload, I write the aforementioned data into the struct every time the pick_next_task is called.\nAs one would expect, the size of the logged data increases significantly within a short time period. Hence, I flush the data by writing it to file after the size of a log increases to a certain value.\nI wanted to ask if there is another, better, way to log this time series data?\nIf not, then what would be a good way to stop the size of the log from exploding? Is there an alternative to writing the data to file? Would using debugfs be a better alternative?\nAny help would be greatly appreciated.\nThank you!"

"I'm building a class with pure virtual functions called Database. The idea is to have a class that handles all the database interfaces (ie: open and close) and can be used on my business layers.\n\nThe Database class will be implemented in several 'flavours' for different databases, like mySqlDatabase and OracleDatabase. \n\nI imagined Database having pure virtual methods with no code - just a header file as follows:\n\nDatabase.hpp\n\nclass Database {\n\n public:\n Database();\n virtual ~Database();\n\n virtual void open(const std::string databasename) = 0;\n virtual void open(const std::string databasename, const std::string username, const std::string password) = 0;\n virtual void open(const std::string databasename, const std::string schema, const std::string username, const std::string password) = 0;\n\n.\n<Other stuff>\n.\n\n}\n\n\nThe three open variations are there to support different database connection requirements, from the simplest one (like Sqlite3 that needs only a filename), to Oracle (that needs all of that variables to connect).\n\nI have some questions about the implementations (let's take oracle for example):\n\na) Shall I need to redeclare the virtual methods again on the derived class header file, like:\n\n class OracleDatabase : public Database {\n\n public:\n OracleDatabase ();\n virtual ~OracleDatabase ();\n\n void open(const std::string databasename);\n void open(const std::string databasename, const std::string username, const std::string password);\n void open(const std::string databasename, const std::string schema, const std::string username, const std::string password);\n}\n\n\nb) How do I structure the implementation of the open methods in the derived class (let´s take Sqlite3)?\n\nvoid Sqlite3Database::open(const std::string databasename){\n ...do some stuff...\n}\n\nvoid Sqlite3Database::open(const std::string databasename, const std::string username, const std::string password) {\n ...do some stuff...\n }\n\nvoid Sqlite3Database::open(const std::string databasename, const std::string schema, const std::string username, const std::string password) {\n ...do some stuff...\n }\n\n\nAm I using the right strategy?

"FileChannel.transferTo() keeps transferring 0 bytes?",
"I asked this question yesterday, and I was convinced that a single-threaded file server will fit my need. Yes, with a single thread, the file server works pretty well(for only small files), it can handle about 300 requests per second, now the problem is that the write(I use FileChannel.transferTo()) part of the server will block for quite a while for serving large files, which keeps other connections from being connected. \n\nI noticed that FileChannel.transferTo() sometimes transfers 0 bytes when transferring large files(around 800KB). It fails with: java.io.IOException: Try again. This was on Android.\n\nBecause I put FileChannel.transferTo() in a loop, I can get the situation where FileChannel.transferTo() runs thousands of times to ultimately transfer the entire file.\n\nMy question is what causes FileChannel.transferTo() fail to transfer the bytes requested? How do I tackle this problem and make my file server more responsively for handling large files?"

"Visual Studio Extensibility Package 2010 and 2012. Is there a way to have one package for both?",
"A while ago I created a Visual Studio Package/Add-In for Visual Studio 2010 (for those curious: http://visualstudiogallery.msdn.microsoft.com/ea23f9a7-a942-45b2-87e6-5df6ff0444ff). If I try to download that and install it in Visual Studio 2012, it doesn't work, I get a version error. \n\nSo my first thought was to see what happens if I try to port it to 2012. I downloaded and installed the VS2012 RC SDK, and basically recreated the whole thing in a separate solution and it all works. What I noticed was that many of the assemblies I had to reference (Microsoft.VisualStudio.*) were now version 11 as opposed to version 10 (for obvious reasons). After copying and pasting all the code over, I got it to work correctly in Visual Studio 2012. \n\nMy question now is this: Is it possible to have one .vsix file for multiple versions of Visual Studio (I'm guessing no.) If not, what's the correct approach to take as far as uploading the different versions? Can I upload two versions of a .vsix? Will the Add-In manager in visual studio pick the correct one automatically? Do I need to create a new package e.g. \"Visual Pastie 2012\"? Just looking for some guidance."

The below code I am using to generate an ICS file and below that is the content of the ICS file. \n\nCode :\n\n Calendar icsCalendar = new Calendar();\n icsCalendar.getProperties().add(Version.VERSION_2_0);\n icsCalendar.getProperties().add(CalScale.GREGORIAN);\n\n String startDateString = new SimpleDateFormat(\"yyyyMMdd'T'hhmmss'Z'\").format(groupNotes.getStartTimestamp());\n String endDateString = new SimpleDateFormat(\"yyyyMMdd'T'hhmmss'Z'\").format(groupNotes.getEndTimestamp());\n net.fortuna.ical4j.model.Date startDt = null;\n net.fortuna.ical4j.model.Date endDateFortuna = null;\n try {\n startDt = new net.fortuna.ical4j.model.Date(startDateString, \"yyyyMMdd'T'hhmmss'Z'\");\n endDateFortuna = new net.fortuna.ical4j.model.Date(endDateString, \"yyyyMMdd'T'hhmmss'Z'\");\n } catch (ParseException e) {\n e.printStackTrace();\n }\n\n java.util.Calendar endDate = java.util.Calendar.getInstance();\n endDate.setTimeInMillis(groupNotes.getEndTimestamp().getTime());\n /* long difference = groupNotes.getEndTimestamp().getTime() - groupNotes.getStartTimestamp().getTime();\n int min = (int) (difference / (1000 * 60));\n Dur dur = new Dur(0, 0, min, 0);*/\n VEvent vEvent = new VEvent(startDt, endDateFortuna, groupNotes.getMnotetag());\n vEvent.getProperties().add(new Description());\n try {\n vEvent.getProperties().getProperty(Property.DESCRIPTION).setValue(groupNotes.getMnotetext());\n vEvent.getProperties().add(new Organizer(\"MAILTO:\" + groupNotes.getNoteCreatorEmail()));\n\n } catch (IOException | URISyntaxException | ParseException e) {\n e.printStackTrace();\n }\n icsCalendar.getComponents().add(vEvent);\n\n FileOutputStream fout = null;\n\n try {\n fout = new FileOutputStream(calFile);\n } catch (FileNotFoundException e) {\n e.printStackTrace();\n }\n\n CalendarOutputter outputter = new CalendarOutputter();\n outputter.setValidating(false);\n\n try {\n outputter.output(icsCalendar, fout);\n return new FileInputStream(\"mycalendar.ics\");\n } catch (IOException | ValidationException e) {\n e.printStackTrace();\n }\n }\n\n\nHere is how my ICS file looks like :\n\nBEGIN:VCALENDAR\nVERSION:2.0\nCALSCALE:GREGORIAN\nBEGIN:VEVENT\nDTSTAMP:20150910T152828Z\nDTSTART;VALUE=DATE:20150911\nDTEND;VALUE=DATE:20150911\nSUMMARY:\nDESCRIPTION:poip\nORGANIZER:MAILTO:[email protected]\nEND:VEVENT\nEND:VCALENDAR\n\n\nNow when I import this, no time is mentioned in Outlook, thunderbird or Evolution. What am I doing wrong? Thank you."

"concatenating staggered columns",
"I am working on a macro to loop through staggered columns of strings and concatenate them. Basically data gets added into the columns over time so I need to make it \"future-proof\". At the moment it picks up all of column H and I but only the first value of J and K. Not sure why it works for half but not the other. I am thinking its to do with my .End(xldown) as i am used to using rows.end(xlup).count to loop through things, but never when it is part of the range?\nHere is my code: \n\nSub Concatenation_for_the_nation()\n\nRange(\"H2\").End(xlDown).Select\nFor i = 1 To ActiveCell.Row\n Range(\"H\" & i).Select\n StrStrONE = StrStrONE & \" \" & Selection\nNext i\nCells(1, 1).Select\n\nRange(\"I2\").End(xlDown).Select\nFor j = 1 To ActiveCell.Row\n Range(\"I\" & j).Select\n StrStrTWO = StrStrTWO & \" \" & Selection\nNext j\nCells(1, 1).Select\n\nRange(\"J2\").End(xlDown).Select\nFor k = 1 To ActiveCell.Row\n Range(\"J\" & k).Select\n StrStrTHREE = StrStrTHREE & \" \" & Selection\nNext k\nCells(1, 1).Select\n\nRange(\"K2\").End(xlDown).Select\nFor l = 1 To ActiveCell.Row\n Range(\"K\" & l).Select\n StrStrFOUR = StrStrFOUR & \" \" & Selection\nNext l\nCells(1, 1).Select\n\nCells(21, 21) = StrStrONE & StrStrTWO & StrStrTHREE & StrStrFOUR\n\nCells(20, 20) = \"Jeff\"\n\nMsgBox \"steve the pirate\"\n\nEnd Sub"

"How to show a div when hovering another div using CSS?",
"I have a div that contains an iframe element that shows a video (song), and another div that shows the lyrics of that song. the div that shows the lyrics is set with display: none;. now, i want to show this div (lyrics) when the div that contains the iframe element with the video is hovered. (I'm not allowed to use Javascript, only CSS).\nWhat i have:\nkaraoke.html:\n<div class="main-container">\n <div class="karaoke" style="top: 30px; left: 30px;">\n <iframe frameborder="0" height="100px" width="180px" src="https://www.youtube.com/embed/tgbNymZ7vqY"></iframe>\n </div>\n <div class="lyrics-w">\n <span class="lyrics">lyrics here</span>\n </div> \n</div>\n\nkaraoke.css:\n.main-container {\n position: relative;\n display: block;\n height: 600px;\n width: 800px;\n background: #00aaee;\n border-radius: 15px;\n margin-top: 70px;\n margin-left: auto;\n margin-right: auto;\n margin-bottom: 70px;\n}\n.karaoke {\n position: absolute;\n display: block;\n height: 140px;\n width: 180px;\n background: #f78a69; \n cursor: pointer; \n border-radius: 10px;\n}\n.lyrics-w {\n position: absolute;\n display: none;\n height: calc(100% - 30px - 30px - 70px - 30px);\n bottom: 30px;\n background: salmon; \n border-radius: 10px;\n left: 50%;\n transform: translateX(-50%);\n width: 260px;\n overflow-x: hidden;\n overflow-y: auto;\n}\n.lyrics {\n position: relative;\n display: block;\n padding: 20px;\n line-height: 26px;\n overflow: hidden;\n text-overflow: ellipsis;\n font-family: Cambria, Cochin, Georgia, Times, 'Times New Roman', serif;\n font-size: large;\n color: #454545;\n font-style: italic;\n line-break: auto;\n}\n.karaoke:hover .lyrics-w {\n display: block;\n}\n\nThe .karaoke:hover .lyrics-w { display: block; } should make the div with the class .lyrics-w visible (with display: block;) when hovering the div with the class .karaoke, but for some reason it doesn't. I used many times this kind of code to change CSS attributes of another elements while hovering specific element, and till now it worked well, I don't understand why it doesn't work here. Maybe because .karaoke and .lyrics-w are independent objects (I mean one is not child of the other)? I don't know.\nAny ideas? Thanks in advance."
