"Making .exe from the Python Script that uses GIS libraries such as geopandas, folium",
"It's a very straightforward and broad question I know but I have very little time so I have to ask. I created an interface to do some GIS calculations and for that I used below libraries in backend.\n\nimport osmnx as ox, networkx as nx, geopandas as gpd, pandas as pd\nfrom shapely.geometry import LineString, Point\nfrom fiona.crs import from_epsg\nimport branca.colormap as cm\nimport folium\nfrom folium.plugins import MarkerCluster\nimport pysal as ps\n\n\nand these for frontend\n\nimport tkinter as tk\nfrom tkinter import ttk\nfrom tkinter.filedialog import askopenfilename, asksaveasfilename, \naskdirectory\nimport backend as bk\n\n\nI'm trying to make it an executable program and I've tried PyInstaller but it did not work because of the dependencies. Is there any way to do it with PyInstaller? or any other libraries? Or what should I do?\n\np.s : I'm using python 3.6\n\n2nd EDIT:\n\nI tried cx_freeze and created a setup.py and build it. After that, when I double click on the program It simply does nothing. No error messages, anything. My code is in below:\n\nimport cx_Freeze\nimport sys\nimport os \n\nPYTHON_INSTALL_DIR = os.path.dirname(sys.executable)\nos.environ['TCL_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tcl8.6')\nos.environ['TK_LIBRARY'] = os.path.join(PYTHON_INSTALL_DIR, 'tcl', 'tk8.6')\n\ninclude_files = [(os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tk86t.dll'), os.path.join('lib', 'tk86t.dll')),\n (os.path.join(PYTHON_INSTALL_DIR, 'DLLs', 'tcl86t.dll'), os.path.join('lib', 'tcl86t.dll'))]\n\npackages = [\"pandas\", \"numpy\", \"tkinter\", \"matplotlib\", \"osmnx\", \"networkx\",\n \"geopandas\", \"shapely\", \"fiona\", \"branca\", \"folium\",\n \"pysal\"]\n\nbase = None\nif sys.platform == \"win32\":\n base = \"Win32GUI\"\n\nexecutables = [cx_Freeze.Executable(\"frontend.py\", base=base, icon=\"transport.ico\")]\n\ncx_Freeze.setup(\n name = \"Network_Analyst\",\n options = {\"build_exe\": {\"packages\":packages,\n \"include_files\":include_files}},\n version = \"0.01\",\n description = \"Network analyst\",\n executables = executables\n )\n\n\nMy program consists of two scripts which are frontend and backend. I'm importing backend on the frontend section, should I add it somewhere in the setup code? And one more thing, I'm working on an environment to do these processes, Is this has an effect on building a setup? \n\nI'm giving a sample from my code to make your understanding better:\n\nIn frontend part I'm calling backend as\n\nimport backend as bk\n\n\nand in the script:\n\nclass Centrality(tk.Frame):\n\n def degree_cent(self):\n print(\"Calculating Degree Centrality\")\n G = self.findG()\n try:\n bk.degree_cent(G, self.t3.get(\"1.0\",'end-1c'), self.t2.get(\"1.0\",'end-1c'))\n except:\n bk.degree_cent(G, self.t3.get(\"1.0\",'end-1c'))\n\n\nIn backend I don't use OOP, I just write the functions such as:\n\nimport osmnx as ox, networkx as nx, geopandas as gpd, pandas as pd\n\ndef degree_cent(G, outpath, *args):\n\n G_proj = ox.project_graph(G) \n nodes, edges = ox.graph_to_gdfs(G_proj)\n nodes[\"x\"] = nodes[\"x\"].astype(float)\n\n degree_centrality = nx.degree_centrality(G_proj)\n degree = gpd.GeoDataFrame(pd.Series(degree_centrality), columns=[\"degree\"])\n\n\nExecutable program still doesn't respond when I'm clicking on it. No respond at all. No any windows event (I've checked it from Windows Event Viewer)."

Somehow, when I pass @response into BugsnagService#notify, the object turns from HTTParty::Response into Hash.\n\nBut if I pass something in for the **options parameter, it will work. So I can call it like this:\n\nBugsnagService.notify(exception, @response, { })\n\n\nI've been trying to figure this one out but I couldn't find anything that would explain this. I'm not sure if there's something wrong with the way I define my parameters or if this is some bug with the HTTParty gem. Can anyone see why this is happening? Thanks!"

"Rails: Appending methods to activerecord (the right way?)",

Let's say I want to do the following:\n\nclass DemoModel < ActiveRecord::Base\n custom_method :first_argument, :second_argument\nend\n\n\nIn order to make this work, I throw in the following:\n\nmodule DemoMethod\n\n def self.included(base)\n base.extend(ClassMethods)\n end\n\n module ClassMethods \n def custom_method(*fields)\n @my_fields = fields\n end\n end\n\nend\n\nActiveRecord::Base.send(:include, DemoMethod)\n\n\nSo far, so good.\n\nThe problem is, I then want to access that my_fields variable from the instance of the model. For example, I might open up form_for with something like:\n\nmodule ActionView::Helpers::FormHelper\n def fields_for(record_name, record_object, options = {}, &block)\n the_fields = record_object.<I WANNA ACCESS @my_fields HERE!!!>.html_safe\n # ...\n end\nend\n\n\nThe difficulty is, 'custom_method' only seems to work if I set the helper as a class method, but that means .self is now the Model (DemoModel) instead of the DemoModel object on which I want to work. I could pass in the object manually with \"custom_method self, :first_argument, :second_argument\", but it seems a little clumsy to ask the users of my wonderful \"custom_method\" gem to have to prepend 'self' to their list of arguments.\n\nSo, the question is, how would a wiser Rails person set values for a specific object through custom_method, and then retrieve them somewhere else, such as fields_for? \n\nAs always, any suggestions appreciated."

"What does nvprof output: \"No kernels were profiled\" mean, and how to fix it",
"I have recently installed Cuda on my arch-Linux machine through the system's package manager, and I have been trying to test whether or not it is working by running a simple vector addition program.\nI simply copy-paste the code from this tutorial (Both the one using one and more kernels) into a file titled cuda_test.cu and run\n> nvcc cuda_test.cu -o cuda_test\n\nIn either case, the program can run, and I get no errors (both as in the program doesn't crash and the output is that there were no errors). But when I try to run the Cuda profiler on the program:\n> sudo nvprof ./cuda_test\n\nI get result:\n==3201== NVPROF is profiling process 3201, command: ./cuda_test\nMax error: 0\n==3201== Profiling application: ./cuda_test\n==3201== Profiling result:\nNo kernels were profiled.\nNo API activities were profiled.\n==3201== Warning: Some profiling data are not recorded. Make sure cudaProfilerStop() or cuProfilerStop() is called before application exit to flush profile data.\n\nThe latter warning is not my main problem or the topic of my question, my problem is the message saying that No Kernels were profiled and no API activities were profiled.\nDoes this mean that the program was run entirely on my CPU? or is it an error in nvprof?\nI have found a discussion about the same error here, but there the answer was that the wrong version of Cuda was installed, and in my case, the version installed is the latest version installed through the systems package manager (Version 10.1.243-1)\nIs there any way I can get either nvprof to display the expected output?\nEdit\nTrying to adhere to the warning at the end does not solve the problem:\nAdding call to cudaProfilerStop() (or cuProfilerStop()), and also adding cudaDeviceReset(); at end as suggested and linking the appropriate library (cuda_profiler_api.h or cudaProfiler.h) and compiling with\n> nvcc cuda_test.cu -o cuda_test -lcuda\n\nYields a program which can still run, but which, when uppon which nvprof is run, returns:\n==12558== NVPROF is profiling process 12558, command: ./cuda_test\nMax error: 0\n==12558== Profiling application: ./cuda_test\n==12558== Profiling result:\nNo kernels were profiled.\nNo API activities were profiled.\n==12558== Warning: Some profiling data are not recorded. Make sure cudaProfilerStop() or cuProfilerStop() is called before application exit to flush profile data.\n======== Error: Application received signal 139\n\nThis has not solved the original problem, and has in fact created a new error; the same happens when cudaProfilerStop() is used on its own or alongside cuProfilerStop() and cudaDeviceReset();\nThe code\nThe code is, as mentioned copied from a tutorial to test if Cuda is working, though I also have included calls to cudaProfilerStop() and cudaDeviceReset(); for clarity, it is here included:\n#include <iostream>\n\n#include <math.h>\n\n#include <cuda_profiler_api.h>\n\n// Kernel function to add the elements of two arrays\n\n__global__\nvoid add(int n, float *x, float *y)\n{\n int index = threadIdx.x;\n int stride = blockDim.x;\n for (int i = index; i < n; i += stride)\n y[i] = x[i] + y[i];\n}\n\n\nint main(void)\n\n{\n\n int N = 1<<20;\n\n float *x, *y;\n\n\n cudaProfilerStart();\n\n\n // Allocate Unified Memory – accessible from CPU or GPU\n\n cudaMallocManaged(&x, N*sizeof(float));\n\n cudaMallocManaged(&y, N*sizeof(float));\n\n\n\n // initialize x and y arrays on the host\n\n for (int i = 0; i < N; i++) {\n\n x[i] = 1.0f;\n\n y[i] = 2.0f;\n\n }\n\n\n\n // Run kernel on 1M elements on the GPU\n\n add<<<1, 1>>>(N, x, y);\n\n\n\n // Wait for GPU to finish before accessing on host\n\n cudaDeviceSynchronize();\n\n\n\n // Check for errors (all values should be 3.0f)\n\n float maxError = 0.0f;\n\n for (int i = 0; i < N; i++)\n\n maxError = fmax(maxError, fabs(y[i]-3.0f));\n\n std::cout << "Max error: " << maxError << std::endl;\n\n\n\n // Free memory\n\n cudaFree(x);\n\n cudaFree(y);\n \n cudaDeviceReset();\n cudaProfilerStop();\n\n \n\n return 0;\n\n}"

This means I don't care and no need to bother about international numbers. \n\nNumbering plan goes like this :\nNPA-NXX-XXXX\n\nI would filter & strip extra space or dash(-) to make into 10 digit correct format. Currently we use MySQL and CouchDB for some other stuff but would prefer to keep in MySQL DB as preferred storage system. \nI'm looking for fast read operation to match numbers during runtime and write can be little slow as mostly insert/update will happen in off hours. \n\nSince it is given that NPA & NXX will never start with 0 so if we can separate \nthem and they can be used as integer type in case of want to breakdown. \n\nFor NoSQL case, it is possible to generate separate document for each area code and then further isolate NXX & XXXX.\nFor RDBMS case, a full number can be stored as indexed integer for fast accessibility. \n\nWhat would be the best database design to store these numbers ? \n\nThanks in advance."

"Public inheritance for all except one function",
"Say I have the following classes:\nclass Car\n{\n ...\npublic:\n void drive(Direction direction);\n void open_door();\n void refuel();\n double get_speed();\n ...\n};\n\nclass SelfDrivingCar: public Car\n{\n CarDrivingProgram *driving_program;\n ...\n};\n\nclass CarDrivingProgram\n{\npublic:\n virtual void drive_car(Car *car) = 0;\n};\n\nclass ExampleCarDrivingProgram: public CarDrivingProgram\n{\n void drive_car(Car *car) override;\n ...\n};\n\nSelfDrivingCar is a Car in every way except the user is forbidden from manually driving it. Instead, CarDrivingProgram drives it via drive_car(...). Using public inheritance seems correct because most operations on a Car could also happen to a SelfDrivingCar. For example, the user might create an array of Cars and then refuel all the Cars in the array, some of which happen to be SelfDrivingCars.\nHowever, using public inheritance exposes the drive(...) method, which the user should not call on a SelfDrivingCar.\nOne solution would be to make the drive(...) method private in SelfDrivingCar, but that's messy, requires all CarDrivingPrograms to be friends in order to access drive(...), and can be circumvented if the user casts a SelfDrivingCar to a Car and then calls drive(...) from the Car.\nAnother solution would be to keep a boolean flag that indicates whether a Car is currently allowed to be driven or not and printing an error if drive(...) is called when the flag is set to "false". For a SelfDrivingCar, this flag would be "false" for most of the time, and CarDrivingProgram would temporarily set this to "true" for the duration of drive_car(...). However, this catches mistakes at runtime rather than at compile time, and the user can still toggle the flag and drive a SelfDrivingCar manually if they really want to.\nUsing protected/private inheritance would be another solution, but that prevents the user from doing something like adding SelfDrivingCars to an array of Cars that are to be later refuelled (described earlier).\nHow do I cleanly forbid the user from calling drive() on a SelfDrivingCar, ideally catching things at compile thing?\nFor clarification: The SelfDrivingCar class still needs a drive(...) function or something like it because CarDrivingProgram needs a way to tell SelfDrivingCar the direction to drive in. CarDrivingPrograms can drive any Car, not just SelfDrivingCars. I want CarDrivingProgram to be able to drive SelfDrivingCars but for the user to be unable to. For example, the user could have an array of pairs of CarDrivingPrograms and Cars, and call carDrivingProgram[i]->drive_car(car[i]) for each pair. I could make all CarDrivingPrograms friends but that's messy."

"how to make a Command Line Interface from a given data model used for GUI",
"HI, guys. I am developing a GUI to configure and call several external programs with Python and I use wxPython for the GUI toolkits. Basically, instead of typing commands and parameters in each shell for each application (one application via one shell), the GUI is visualizing these parameters and call them as subprocesses. I have built the data model and the relevant view/gui controls (mainly by using the observer pattern or try to separate model with the gui widgets), and it is OK. \n\nNow there is a request from my colleagues and many other people (even including myself), is it possible to have a command line interface for the subprocesses, or even for the whole configuration GUI, based on the data model I already have? This is due to the fact that many people prefer CLI, CLI is better in reliability, and also needs of programmer debugging and interfacing. \n\nAs I am rather new to developing a CLI, I really need some help from you. I appreciate any advice and information from you. \n\nto be more specific, \n\n\nIf I completely forget about the data model built for GUI, start from scratch. Is there some good materials or samples to have a reference?\nIf I still want to utilize the data model built for GUI, is it possible? If possible, what shall I do and any samples to follow? Do I need to refactor the data model?\nIs it possible to have the CLI and GUI at the same time? I mean, can I take the CLI as another view of the data model? Or there is other right approach? \n\n\nThank you very much for your help!!"

"Leaflet Contextmenu - How to pass a marker reference when executing a callback function (non-geoJSON marker)",
"I am having troubles with executing callback functions on markers (in my case they are circle and semiCircle markers). The marker context menu extends map's context menu with additional marker-specific operations. Map context menu callbacks are working properly. Marker additional menu options are shown, but I cannot execute the corresponding functions (for example getting Lat and Lon of a marker). The error in both variants that I tried (see below) is \"Uncaught TypeError: Cannot read property 'getLatLng' of undefined\".\n\nBelow is shown the code that I am using.\n\nMarkers are created from external JS file and stored in a layerGroup.\n\nVariant 1 - Using event \"contextmenu.show\" as suggested in contextMenu documentation.\n\nCreating layerGroups with Circle markers:\n\nfor(i in sites) {\nvar title = sites[i].ID, \n loc = sites[i].loc, \n object = sites[i].Type,\n marker = new L.circle(new L.latLng(loc), {radius: radsiteinit+50,color: 'gold', weight: 3, title: title, pane: \"sitePane\",\n contextmenu: true,contextmenuItems: [{text: 'Show Charts',index:0}, {separator: true, index: 1}]} ).\n bindPopup(object+': '+ title ).on('click', onClick);\n\n layerSites.addLayer(marker);\n}\n\n\n\"contextmenu.show\" event:\n\n mymap.on('contextmenu.show', function (event) {\n\n var latlngs = event.relatedTarget.getLatLng();\n\n});\n\n\nAs mentioned above produced error is \"Uncaught TypeError: Cannot read property 'getLatLng' of undefined\". Also event is fired before user gets the chance to select and option from context menu. What I need is to fire the event after user selects some marker-specific options from context menu.\n\nVariant 2 - With definition of callback function.\n\nCreating layerGroups with Circle markers - the difference here from above is that I added callback function is context menu definition:\n\nfor(i in sites) {\nvar title = sites[i].ID, \n loc = sites[i].loc, \n object = sites[i].Type,\n marker = new L.circle(new L.latLng(loc), {radius: radsiteinit+50,color: 'gold', weight: 3, title: title, pane: \"sitePane\",\n contextmenu: true,contextmenuItems: [{text: 'Show Charts',callback:showCharts,index:0}, {separator: true, index: 1}]} ).\n bindPopup(object+': '+ title ).on('click', onClick);\n\n layerSites.addLayer(marker);\n}\n\n\nCallback function definition:\n\nfunction showCharts(e) {\n\n var latlngs = e.relatedTarget.getLatLng();\n\n};\n\n\nThe same error here.\n\nI am very new to JavaScript, so I guess I do something wrong when I am trying to pass marker's reference to the function (var. 2) or event (var. 1).\n\nBecause I am stuck a lot, I would appreciate getting some advice.\n\nThank you in advance!\n\nEDIT\nIn the link you can find a JS Bin example of variant 2:\nJS Bin Example"

I could clear clear the SelectedItem and Text but the SearchText was left behind. It is read only and cannot be changed by binding.\n\nExample: AutoCompleteBox with a list of Countries. When the user wants to enter Australia they enter 'au' at this point the list appers with Austria and Australia. The user can then select Australia and move on. At the end of editing they click on a 'Save' button. At this point it is likely that you would want to clear the data forn for entering new data.\n\nEven if you have bindings to the SelectedItem and the Text properties and you set them to 'null' and string.Empty respectively the SearchText property remains and the AutoCompleteBox will not clear but will contain 'au'."

"Database table called Events that contains event templates from which any number of single events can be generated that have a foreign key relationship referencing the same Event table with the template event ID as the primary key, so a self referencing table. There is another table called EventRestriction which has a foreign key to both the Event table and a Customer table. The foreign key value to the Event table is the event ID of the event template record. What I am struggling to do is the following:\n\nFrom the Event table get ALL events whose event template ID matches the event ID in the EventRestriction table and where the customer ID in the EventRestriction table equals a specific customer.\n\nThis is using EF 6 code first approach against SQL Server 2012.\n\nThis is the existing query that I am trying to build on;\n\nvar query = Events\n .Include(x => x.Location)\n .Include(x => x.Facility)\n .Include(x => x.EventType)\n .Include(\"Tickets.WebSaleItem.Product\")\n .Include(\"Tickets.SeatingTemplateCategory\")\n .Include(\"Tickets.SeatReservations\")\n .Include(x => x.SeatingTemplate.SeatingUser)\n .Include(x => x.SeatingTemplate.SeatingTemplateCategories)\n .Include(\"Facilities.Facility\")\n .Include(\"EventCapacityDistributions.CapacityDistributionSource\")\n .Include(\"EventCapacityDistributions.EventCapacityUsages.WebSaleItem.Product\")\n .Include(\"EventCapacityUsages.Bookings.EventBookingFacilities.Facility\")\n .Include(\"EventCapacityUsages.EventBookingReservation.EventBookingFacilities.Facility\")\n .AsQueryable();\n\n\nI have to use this is a base query as all of the includes are required for further processing against the initial result set.\n\nI have tried the following so far.\n\nI have declared the routing relationship between Event, EventRestriction and Customer so there are many-to-many relationships and hashsets defined with the appropriate (I think) navigation properties.\n\nI added this to the above query\n\nquery = query.Where (x => x.EventRestriction.Any (tte => tte.CustomerID == customerID));\n\n\nThis returns the single template event based upon event ID and customer ID.\n\nI then tried this:\n\nquery = query.Where(x => x.EventRestriction.Any (tte => (tte.CustomerID == customerID && tte.EventID == x.EventID) || (tte.EventID == x.EventTemplate.EventID && tte.CustomerID == customerID)));\n\n\nMy thinking was that doing the OR would do it but no joy and I get the same result as previous with just the single event.\n\nI am thinking that I am going in the right direction but missing a vital element.\n\nOne thing that did work for me though was doing this before building query:\n\nList<Guid> ttEventIDs = new List<Guid>();\n\nttEventIDs = EventRestriction.Select(tte => tte.EventID).ToList();\n\n\nI then used the resulting list like this;\n\nquery = query.Where(x => ttEventIDs.Contains(x.EventTemplate.EventID));\n\n\nNow this did give me the results I was expecting BUT using a contains is not really going to work as the number of ID's could be huge!!!\n\nI am thinking a table join would work better?\n\nSo basically what I expect is that if Event table contains a template event from which 100 individual events have been generated with an EventTemplateID foreign keyed to the original template event ID AND EventRestriction table contains one single record that comprising of the 'CustomerID' and the EventID of the original template my query needs to return NOT the single event record BUT the 100 events whose EventTemplateID matches the EventRestriction event ID.\n\nI hope this makes sense? Any guidance will be greatly appreciated."

Thanks.\nUPDATE:\nI created a docker-compose.yml file and is working but still I can't find any guide to see if it is a good yml file (best practices etc.)\nversion: '3'\n\nservices:\n web:\n build: .\n command: npm run dev\n ports:\n - '3000:3000'"

"Laravel Migration - column already exists",
"Several months ago, I was working late and needed to create a new column for a postgres table. I added the column through the command line using the standard heroku/postgres commands. I quickly realized how silly this was, deleted the column and then created the necessary migration to add it.\n\nI recently took that laravel app and created a pipeline with it as the production app. I created a new staging app and set up a database for it. When I ran the migrations, I got an error saying that a column already existed. As you may have guessed, this is the same column that I had messed up before.\n\nSince the migration failed after the database was created, I was able to delete the column in question, rerun the migration, and everything was OK. I do not understand why the column already existed except to guess that it was some artifact of my adding it manually (there was no error in the migrations).\n\nI am worried that this same error will happen when I push the staging code to production and have to rerun my migrations. Obviously, in the production app I can't just delete the column in question as it has data. \n\nAny ideas as to why this would happen and what I could do to fix the issue if it arises when I push the code into production?"
