| surface 3D plotting using matplotlib Posted: 19 Apr 2021 08:00 AM PDT I want to plot a 3D surface plot. Luckily a lot of help is available. but I need to import my file for plotting. I have a file with 3 columns as x, y, and z with a long list of values and I want to import those values for as x y and z values. I have the following code. from mpl_toolkits import mplot3d %matplotlib inline import numPy as np import matplotlib.pyplot as plt import csv fig = plt.figure() ax = plt.axes(projection='3d') x = import first column y = import second column z = import third column surf = ax.plot_surface(x, y, z, rstride = 8, cstride = 8, alpha = 0.8, ) fig.colorbar(surf, ax = ax, shrink = 0.5, aspect = 5) ax.set_xlabel('X-axis') ax.set_xlim(-5, 5) ax.set_ylabel('Y-axis') ax.set_ylim(-5, 5) ax.set_zlabel('Z-axis') ax.set_zlim(np.min(z), np.max(z)) ax.set_title('3D Energy plot') ax.plot_surface(x, y, z) # for surface plotting plt.show()
Kindly give me suggestions.  |
| javascript: Get JSON to classify the website Posted: 19 Apr 2021 08:00 AM PDT I've got a set of URL data (their order is disordered). I want to sort them, create corresponding node classification, and let the commonly used URLs be classified as the front. The expected generated node should be the following HTML structure a { text-decoration: none; } .item-wrap+.item-wrap { border-top: 2px solid #6d28d9; margin-top: 30px; }
<div class="container"> <div class="item-wrap"> <h3>commonly-used</h3> <div class="items"> <a href="">stackoverflow</a> </div> <div class="items"> <a href="">github</a> </div> </div> <div class="item-wrap"> <h3>search-type</h3> <div class="items"> <a href="">google</a> </div> <div class="items"> <a href="">wikipedia</a> </div> </div> <div class="item-wrap"> <h3>study-type</h3> <div class="items"> <a href="">w3c</a> </div> <div class="items"> <a href="">vue</a> </div> <div class="items"> <a href="">react</a> </div> </div> <div class="item-wrap"> <h3>tool-type</h3> <div class="items"> <a href="">remove bg</a> </div> </div> <div class="item-wrap"> <h3>movie-type</h3> <div class="items"> <a href="">movie site</a> </div> <div class="items"> <a href="">movie site2</a> </div> </div> </div>

| Verification with IvalidatableObject Posted: 19 Apr 2021 08:00 AM PDT I applied the IvalidatableObject Interface to the student class coming from the database. However, I do not know how to do this verification on the Form1 side. How can I verify the student class in Form1 and show the error messages to the user? Thanks. public partial class students:IValidatableObject { public int StudentId { get; set; } public short StudentMemberNum { get; set; } public string StudentName { get; set; } public string StudentSurname { get; set; } public System.DateTime StudentBirthDate { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { if (string.IsNullOrEmpty(StudentName)) { yield return new ValidationResult("The student's name is required.", new string[] { "StudentName" }); } } }

| R caption contains "&" Misplaced Alignment tabs Posted: 19 Apr 2021 08:00 AM PDT I have a kable table that works normally, but as the amount of tables I need per 'user' is more than a page, I need to add a caption in order for the tables to be comprehensible. I have the following code. name <- "This & That" kable(head(mtcars), format = "latex", row.names = FALSE, caption = paste(as.character(sub("&", "\\&",name)), "Car Score Input")) %>% kable_styling(full_width = FALSE, font_size = 10,latex_options = "HOLD_position", position = "left") %>% row_spec(row = 0, bold = TRUE, underline = F, background = "orange", color = "white", italic = FALSE, monospace = FALSE, strikeout = FALSE) %>% print(floating = FALSE, row.names = FALSE) as an example. the name variable is sometimes something like "This & That" originally, i just had 'name' in the paste function but I get the following error:
! Misplaced alignment tab character &. <argument> ...ab:unnamed-chunk-6} This & That Car Score Input} name changes and goes through a bunch of other names, some with ampersand and some without
As you can see, I've found some forums that advise for adding \\ to the front of the character to avoid it thinking it is an escape code, but it seems no matter what I try I cannot get it to be thought of as a character. the as.character(sub("&", "\\&", name)) has been nested, I tried sub alone, before pairing it with as.character I'm just running out of ideas. the kable eventually loops through a variety of names, I even tried assigning the sub function output to name prior to adding it to the caption, it does appear as This \\& That however, I get the same error in the captio.  |
| Spring rspec not speeding up tests Posted: 19 Apr 2021 08:00 AM PDT Running a single test in our test suite takes anywhere from 20 - 30 seconds. Prior to adding spring and spring-commands-rspec, the output from running a test would look like this. Finished in 21.99 seconds (files took 21.64 seconds to load) 1 example, 0 failures Randomized with seed 52406
The 22 second file load time suggested that adding the aforementioned gems would help, but after doing so the test is still just as slow. The new output (see below) suggests the file time has in fact been drastically improved (down from 21.64 seconds to 1.25 seconds), but the overall speed of the test is basically the same. This seems very odd and unexpected based on what I have read about the expected effects of adding these gems. Finished in 21.86 seconds (files took 1.25 seconds to load) 1 example, 0 failures Randomized with seed 7594
Any thoughts on why the test is still just as slow, and does anyone have tips on how to fix this/speed up the test? Thanks.  |
| Does DO-178C requires qualified complier? Posted: 19 Apr 2021 08:00 AM PDT In the DO 178C text, the "development tools" and "verification tools" are required to be qualified. A complier is certainly a development tool. But when searching "DO 178C qualified C compilers" I did not really find a compiler for C language. Instead, some articles said "DO 178C does not require to qualify compliers". Could someone help to explain why?  |

| Insert or Update Documents in MongoDB from a CSV using Python Posted: 19 Apr 2021 08:00 AM PDT I'm trying to insert/update documents in MongoDB based on information that I have in a CSV. Where if the first header of the CSV customer_id doesn't exist then it should create a new document but, if it does exist then it should just update all the values in the document. I have the script built that will look for the customer_id and if it doesn't exist then it will create the new document but, having trouble getting the update part working. Do you have to specify each header that needs to be updated or is there a more efficient way of updating by utilizing the headers from the CSV in the event new headers are added later on so that the script wouldn't have to be updated to specify the new headers: import csv from pymongo import MongoClient conn = MongoClient('localhost', 27017) db = conn.shipping collection = db.sales file = csv.reader(open("shipping_list.csv"), delimiter=',') header = ["customer_id", "customer_name", "sales_rep", "purchase_date", "region", "purchase_price", "shipping_status", "products_purchased"] for each in file: if collection.count_documents({ 'customer_id': each[0] }) == 0: row={} for n in range(0,len(header)): row[header[n]] = each[n] collection.insert_one(row) else: row={} for n in range(0,len(header)): row[header[n]] = each[n] collection.update({'customer_id': each[0]}, row)

| Traefik with nip.io Posted: 19 Apr 2021 07:59 AM PDT I'm trying to expose some applications using traefik and nip.io My docker-compose file looks as the following version: '3.3' services: traefik: image: traefik:1.7-alpine command: --web --docker --docker.domain=app.test --logLevel=DEBUG ports: - 80:80 - 8080:8080 volumes: - /var/run/docker.sock:/var/run/docker.sock:ro whoami: image: tons/whoami-go labels: - "traefik.port=8080" - "traefik.frontend.rule=Host:whoami.127.0.0.1.nip.io"
But I can't reach my service $ curl -vvv whoami.127.0.0.1.nip.io

Notably the host header is sent correctly with both requests. I have the same issue using jwilder/nginx-proxy but I have no problem when I'm using nip.io with Kubernetes ingress regardless of using Traefik or Nginx. Anyone got a clue about what's wrong?  |

| Flexbox is not wrapping contents Posted: 19 Apr 2021 07:59 AM PDT I'm using ordered lists (ol) as the basis for this flexbox layout. But the wrapping is not cooperating all of a sudden. Maybe squarespace has messed with the default properties for ordered lists. Either way, the text refuses to wrap within the ol li ol li element and it looks like this:

| ClassCastException with IWorkbenchPage.hideActionSet("org.eclipse.ui.WorkingSetActionSet") Posted: 19 Apr 2021 08:00 AM PDT The eclipse bundled with RCP thick client has recently upgraded from Eclise 4.2.2to Eclipse Neon 4.6.3.

| Is it safe to use function references to register and unregister a listener? Posted: 19 Apr 2021 08:00 AM PDT I recently found myself writing the following code: fun listener() { // Do some stuff adapter.removeLoadStateListener(::listener) } adapter.addLoadStateListener(::listener)
A colleague remarked on the fact that val x1 = ::listener val x2 = ::listener x1 == x2 //true x1 === x2 //false
However, var mySet = mutableSetOf<() -> Unit>() fun a() { } fun b() { } mySet.add(::a) mySet.add(::b) mySet.remove(::a) mySet.contains(::a) // false mySet.contains(::b) // true
Based on this I get the impression I do not understand ::myFun properly and I start to question if my original code is safe to use. TL;DR - Is it safe to use
::listener to reference a method to be used as a listener and that will need to be referenced multiple times (e.g. add + remove)? - What is actually going on behind the scenes regarding anonymous classes etc.?

| Stripe - when I cancel subscription, no money refunded? Posted: 19 Apr 2021 08:00 AM PDT I am using Stripe Checkout to process the checkout form. I've made an "Cancel Subscription" Button on front (using React.js) and I'm sending api call to cancel the subscription by id. Subscription is being canceled successfully, but money are not refunded to the customer? For example: I have subscribed today (per month), and I want to cancel my subscription tomorrow? The money for 29 days or 30 should refunded to me, right? Node JS code: const deleted = await stripe.subscriptions.del(id, { prorate: true, invoice_now: true });
I'm seeing on Stripe dashboard when I delete the subscription, the money value are not changing. Thanks.  |
| Issue combining inner and outer joins in Oracle Posted: 19 Apr 2021 07:59 AM PDT I'm trying to simplify a query against an Oracle database that uses multiple inner joins against the same table. I know the multiple joins against the same table can be cleaned up with outer joins, but I'm failing to elicit the same results. Below are the tables listing only the columns needed for the query. The "link" column in table X maps to the ID, ID2, and ID3 columns in tables A, B, and C respectively. **Table A** id **Table B** id id2 nm **Table C** id3 nm **Table X** cfgnum link
Existing (working query): SELECT COUNT(*) FROM A, X, X X1, X X2, B, C WHERE X.cfgnum = 9999 AND A.id = X.link AND X.cfgnum = X1.cfgnum AND X.cfgnum = X2.cfgnum AND B.id2 = X1.link AND B.id = A.id AND C.id3 = X2.link AND C.nm = B.nm;
The below was my attempt to rewrite, but it returns substantially different results. With the comments in place it does return the right number of rows against the linking X table. SELECT COUNT(*) FROM X LEFT JOIN A ON X.link = A.id LEFT JOIN B on X.link = B.id2 --AND A.id = B.id LEFT JOIN C on X.link = C.id3 --AND B.nm = C.nm WHERE cfgnum = 9999 AND COALESCE (A.id, B.id2, C.id3) IS NOT NULL;
Any help is appreciated!  |
| WooCommerce Select2 Dropdown default sorting filter colors CSS Posted: 19 Apr 2021 08:00 AM PDT I have been trying to change the colours for the hovered default sorting filter on the woocommerce shop page but I cannot seem to find the selector in Google Chrome developer tools, I can't seem to find the CSS that is controlling the colour of this hover element. The solution below works for the country selector dropdown only it seems, but it does not change the default sorting hover colour. Does anyone know the correct selector for the default sorting filter selector, please? .select2-container--default .select2-results__option[aria-selected=true]{ background-color: #FF0000;} .select2-container--default .select2-results__option[data-selected=true]{ background-color: #0000FF;}

| Import-Export Call Order in NodeJS Posted: 19 Apr 2021 08:00 AM PDT This is a "code theory" question. So imagine this scenario, I am using the global namespace in a package. I have a main entrypoint file, some class files that I export, and some utility files the classes use. Here's a theoretical file structure: /index.js (main entrypoint) /src |_/source.js (exporting function for src folder) |_/utils |_/headers.js |_/constants.js |_/classes |_/class1.js |_/class2.js
In constants.js I define some global variables and then export an object that uses some global variables.
/src/utils/constants.js const foobar = 'foo'; global.foobar = foobar; export default { foo: global.foobar, }
In some class file I import constants.js.
/src/classes/class1.js import constants from '../utils/constants.js' export default class Xyzzy { function baz() { return constants.foo + 'baz' } }
And finally in the entrypoint file I import source.js which imports /src/classes/class1 and /src/classes/class2 and exports both of them, then define some global variables.
/index.js import source from '/src/source.js' export default function index() { global.foobar = 'bar' return { class1: source.class1, class2: source.class2, } }
What would be the assignment order of global.foobar, what is the final result, and most importantly why does this happen? Thanks!  |
| How would I be able to detect when a collision shape polygon has made a circle with collision Posted: 19 Apr 2021 08:00 AM PDT This is a hard idea to put into a question, I have made a system where the player draws circles on screen, I want the player has either touched another line of its self start a new circle from that position, the issue I am having is having no clue on how would I make it collide, I have an idea but not sure if it will work, my idea is too simply use a different collision shape that creates its self on points that connect each other and when the mouse collides with that specific collision shape start again, is this the best option I have or is there another way of detecting when a circle is made. heres a video of what I want: https://youtu.be/wSolVcaIszE?t=998 and heres my video of what I have: https://www.youtube.com/watch?v=BDnd-n3PEdQ code: extends Node2D var points_array = PoolVector2Array() var index : int = 0 onready var collision = $Area2D/CollisionPolygon2D func _physics_process(delta): collision.polygon = points_array if Input.is_action_just_pressed("Left_click"): #This sets a position so that the next line can work together points_array.append(get_global_mouse_position()) # This makes a empty vector and the mouse cords is assigned too it points_array.append(Vector2()) if Input.is_action_pressed("Left_click"): #This checks the distance between last vector and the mouse vector points_array[-1] = get_global_mouse_position() # Gets the last position of the array and sets the mouse cords if points_array[index].distance_to(get_global_mouse_position()) > 20: points_array.append(get_global_mouse_position()) index += 1 if points_array.size() > 25: # This adds a length to the circle/line so it wont pass 18 mini lines index -= 1 points_array.remove(0) #Removes the first array to make it look like it has a length if Input.is_action_just_released("Left_click"): # This just clears the screen when the player releases the button points_array = PoolVector2Array() index = 0

| How to add data to a json file while making use of multiproccesing? Posted: 19 Apr 2021 08:00 AM PDT I'm using a user-friendly json based document oriented database named TinyDB. But I'm unable to add multiple pieces of data to my database because I'm making use of multiproccesing. After a while I get the error that id x already exists in the database (this because 2 or more processes are trying to add data at the same time). Is there any way to solve this? Every run I insert new unique params. Example params: params = {'id' = 1, 'name': 'poop', 'age': 99}
Code: resultsDb = TinyDB('db/resultsDb.json') def run(params): resultsDb.insert({'id': params['id'], 'name': params['name'], 'age': params['age']}) maxProcesses = 12 # Cores in my pc for i in range(maxProcesses): processes.append(Process(target=run, args=(params,))) for p in processes: p.start() for p in processes: p.join()

| Access to TelemetryConfiguration object from C# script (csx) in Azure Function Posted: 19 Apr 2021 08:00 AM PDT I need to inject a TelemetryProcessor into existing TelemetryConfiguration (Application Insights) to modify default Azure Function behavior.

| issue SeqHmm data format Posted: 19 Apr 2021 08:00 AM PDT I have the data which is biofam3c in package SeqHMM in list format. I wanted to see it in matrix form. I used this command matrix_biofam3c= matrix(unlist(biofam3c), ncol=16, byrow= TRUE)
But its results was confusing . Then I also tried to change matrix_biofam3c into list using a command U= as.list(as.data.frame(matrix_biofam3c))
it gives not similar results like given form in package (List of length 4). I request please, suggest the right way to make biofam3c in matrix data (like biofam in package TraMineR). And also how to convert it again so it becomes like list as it is given there.  |

| Kotlin MPP expect / actual with different signatures Posted: 19 Apr 2021 07:59 AM PDT I have a manager class that has an Android and iOS impl (from a 3rd party lib). "ex. MyManagerImpl()". To construct the 3rd party manager, iOS does not require a Context but Android does. I created a common class "MyManager" which pulls out all the common methods needed to be called within commonMain. //commonMain expect class MyManager { fun method1() companion object Factory { makeManager(): MyManager } } val manager = MyManager.Factory.makeManager() // ex intended usage //androidMain MyManagerImpl(context: Context) { fun method1() } actual class MyManager private constructor(manager: MyManagerImpl) { .. actual companion object Factory { override fun makeManager(): MyManager { return MyManager(MyManagerImpl(?how to get context?)) } } } //iosMain MyManagerImpl() { fun method1() } actual class MyManager private constructor(manager: MyManagerImpl) { .. actual companion object Factory { override fun makeManager(): MyManager { return MyManager(MyManagerImpl()) } } }
What is the cleanest way to merge the two implementations? Is it possible to do so even tho they have different constructor dependencies? We would like to be able to construct the classes lazily within commonMain. Is this possible?  |
| Define a list of optional keys for Typescript Record Posted: 19 Apr 2021 08:00 AM PDT I want to type an object which can only have keys 'a', 'b' or 'c'. So I can do it as follows: Interface IList { a?: string; b?: string; c?: string; }
They are all optional! Now I was wondering if this can be written with Record in just one line type List = Record<'a' | 'b' | 'c', string>;
The only issue is that all keys need to be defined. So I ended up with type List = Partial<Record<'a' | 'b' | 'c', string>>;
This works, but I can imagine there is a better way to do this without Partial. Is there an other way to make the keys optional inside Record ?  |
