Is it php or perl? Posted: 22 May 2022 12:35 AM PDT I want to integrate an API from a partner, but from the example of the code given I can't figure out if it's php or perl. Because in php it could not work. Thank you in advance for your help. my $secret = 'xxxxxxxx'; my $path = '/api/v1/order'; my $content = '{"partner_order_id":"xxxxx-xxxxx-xxxx1"}'; my $signature = hmac_sha512_base64( sha256($path.$content), $secret );

Spring boot starter webflux with TCP server Posted: 22 May 2022 12:34 AM PDT By default when importing spring webflux <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </dependency> a HTTP server is created. Which bean could I declare or override to use TCP server (https://projectreactor.io/docs/netty/release/api/reactor/netty/tcp/TcpServer.html) instead? Best Regards

Passing argument to canvas function in reportlab Posted: 22 May 2022 12:34 AM PDT I am referencing to the sample code here to create a document with reportlab, particularly the following chunk of code: """ examples of reportlab document using BaseDocTemplate with 2 PageTemplate (one and two columns) """ import os from reportlab.platypus import BaseDocTemplate, Frame, Paragraph, NextPageTemplate, PageBreak, PageTemplate from reportlab.lib.units import inch from reportlab.lib.styles import getSampleStyleSheet styles=getSampleStyleSheet() Elements=[] doc = BaseDocTemplate('basedoc.pdf',showBoundary=1) def foot1(canvas,doc): canvas.saveState() canvas.setFont('Times-Roman',19) canvas.drawString(inch, 0.75 * inch, "Page %d" % doc.page) canvas.restoreState() def foot2(canvas,doc): canvas.saveState() canvas.setFont('Times-Roman',9) canvas.drawString(inch, 0.75 * inch, "Page %d" % doc.page) canvas.restoreState() #normal frame as for SimpleFlowDocument frameT = Frame(doc.leftMargin, doc.bottomMargin, doc.width, doc.height, id='normal') #Two Columns frame1 = Frame(doc.leftMargin, doc.bottomMargin, doc.width/2-6, doc.height, id='col1') frame2 = Frame(doc.leftMargin+doc.width/2+6, doc.bottomMargin, doc.width/2-6, doc.height, id='col2') Elements.append(Paragraph("Frame one column, "*500,styles['Normal'])) Elements.append(NextPageTemplate('TwoCol')) Elements.append(PageBreak()) Elements.append(Paragraph("Frame two columns, "*500,styles['Normal'])) Elements.append(NextPageTemplate('OneCol')) Elements.append(PageBreak()) Elements.append(Paragraph("Une colonne",styles['Normal'])) doc.addPageTemplates([PageTemplate(id='OneCol',frames=frameT,onPage=foot1), PageTemplate(id='TwoCol',frames=[frame1,frame2],onPage=foot2), ]) #start the construction of the pdf doc.build(Elements) In functions foot1 and foot2, I want to pass arguments into to customize the canvas setup. For eg.: def foot1(canvas,doc, page_width, page_height): canvas.saveState() canvas.setPageSize((page_width, page_height)) canvas.setFont('Times-Roman',19) canvas.drawString(inch, 0.05 * page_width, "Page %d" % doc.page) canvas.restoreState() I then modify the last few lines as following: ... from reportlab.lib.pagesizes import letter pW, pH = letter pW, pH = pH,pW #basically switch to landscape size doc.addPageTemplates([PageTemplate(id='OneCol',frames=frameT,onPage=foot1(pW,pH), PageTemplate(id='TwoCol',frames=[frame1,frame2],onPage=foot2), ]) This gives me the following error: TypeError: foot1() missing 2 required positional arguments: 'page_width' and 'page_height' If someone could help explain how this ```addPageTemplates``` calls the ```foot1``` function and how to pass additional arguments besides ```canvas``` and ```doc```? The ```report_lab``` user guide [here](https://www.reportlab.com/docs/reportlab-userguide.pdf) does not have detailed source on this.

Wait for NgOnInit to complete inside ngAfterViewInit Posted: 22 May 2022 12:35 AM PDT I am loading some data in ngOnInit that I need to access inside of ngAfterViewInit. Specifically, Google Maps API, where I'm loading GPS coordinates from the database, then I need to add them to the map upon creation. I'm creating the map itself in ngAfterViewInit. I guess I could move the whole thing to AfterViewInit, but I thought I'd ask if there's a good way to wait for ngOnInit to finish before using the data in AfterViewInit, in case I need it in the future for other projects. ngOnInit() { this.loadGpsCoordinates(); } ngAfterViewInit() { var elem = document.getElementById('map'); if (elem != null) { this.map = new google.maps.Map(elem, { center: { lat: -32.3881373, lng: 55.4343223 }, zoom: 17, disableDefaultUI: true }); // Now loop through GPSCoordinates to add Markers // But wait! What if the coords aren't loaded yet?! ... }

Pyplot 3d, customize colors Posted: 22 May 2022 12:35 AM PDT I'm plotting the spread using pyplot: fig = plt.figure(figsize = (12, 12)) ax = fig.add_subplot(projection = '3d') x = dataframe.AGE # X y = dataframe.BMI # Y z = dataframe.BP # Z ax.scatter(x, y, z) ax.set_xlabel("AGE") ax.set_ylabel("BMI") ax.set_zlabel("Bermuda plan (BP)") plt.show() How can I specify the color for these parameters? So x is red, y is blue, z is green

MudTextField sends HTTP request at every keystroke Posted: 22 May 2022 12:35 AM PDT I use MudTextField for a login form. Whenever a user types something into the text field the application sends the current state to the server. Example: <MudTextField Label="Username" Class="mt-3" @bind-Value="user.username" /> It should only send the state when a user klicks on the login button. Any ideas on how to disable it? Thank you. EDIT: Added more information for clarification. This only happens when using a MudTextField component. Using a custom component with a HTML input field and vanilla razor two-way binding will not display the same behavior. E.g: <div class="form-floating mb-1"> <input type="text" class="form-control" id="username" @bind="@user.username" placeholder="name@example.com"> <label for="username">Username</label> </div> Pic related is the output from the network panel with long-polling enabled as a transport mechanism After browsing the MudBlazor website for information it seems that the Immidiate attribute would be the right option for it but I can't make it work.

Create a large table with ordertypes as column or using separate tables [closed] Posted: 22 May 2022 12:34 AM PDT Background I work at a distribution center from which we deliver goods to about 150 stores on a daily basis. Each store places two orders (each order has different storing conditions) a day with a quantity varying from 500 to 3500 products. All stores have fixed delivery times with a margin of one hour. I started creating a production forecasting and control tool in MS Access which will be used to create a forecast per working hour for order picking, so the warehouse manager can distribute his employees over the day to have each order ready in time for transport. The database should hold up to 6 weeks of history per store per storage condition per day from which I can calculate a forecast. Besides that every day the store gets an order advisory which is used as an starting point for the store when placing the order. I also want to store these advisory, so I can use this to update my forecasting method. After that the store confirms the order and we start to work. I have a table with all the delivery times for each store and from there a calculated time when the order should be ready on dock. Besides that I've a table with productivities per storage condition. With the combination of these two tables and the forecast I should be able to calculate how late an order should be released for production and what production capacity (= employees) should be available at what hour of the day. Question What is the best way of arranging these different types of orders? I'm looking at three different scenarios, where I'm thinking of using the first one: Scenario 1: One table Week WeekDay StoreID StorageCondition Ordertype SumOfProducts 20 1 101 No Condition Forecast 1400 20 1 101 Max. 7 degrees Forecast 1200 20 1 101 No Condition Advice 1100 20 1 101 Max. 7 degrees Advice 1300 20 1 101 No Condition Order 1250 20 1 101 Max. 7 degrees Order 1150 This table would contain 6 weeks of 7 days for 150 stores with 6 records a day = 38K records. With this structure I can only add and delete records and don't have to update records. Scenario 2: One table with different columns Week WeekDay StoreID StorageCondition ForecastSOP AdviceSOP OrderSOP 20 1 101 No Condition 1400 1100 1250 20 1 101 Max. 7 degrees 1200 1300 1150 This table would only contain 12K records, but besides adding and deleting I should also be updating records. Scenario 3: Three tables tblOrderForecast Week WeekDay StoreID StorageCondition SumOfProducts 20 1 101 No Condition 1400 20 1 101 Max. 7 degrees 1200 tblOrderAdvice Week WeekDay StoreID StorageCondition SumOfProducts 20 1 101 No Condition 1100 20 1 101 Max. 7 degrees 1300 tblOrderRealization Week WeekDay StoreID StorageCondition SumOfProducts 20 1 101 No Condition 1250 20 1 101 Max. 7 degrees 1150 With this scenario I would have three tables with 12K records, but I'm able to only add and delete records.

Android Studio: “Execution failed for task ':app:mergeDebugResources'” if project is created on drive C: Posted: 22 May 2022 12:33 AM PDT I added Google Play services as a dependency in my current project. If I save the project on the C: drive, I get the following error while syncing up the project: Error: Execution failed for task ':app:mergeDebugResources'. > Error: Failed to run command: C:\Program Files (x86)\Android\android-studio\sdk\build-tools\android-4.4.2\aapt.exe s -i C:\Users\ashokp\Desktop\Studio\AndroidV2SDK_AndroidStudioFormat\Google Play Services\SampleApplication\AndroidV2SDKSampleApp_GooglePlayServices\app\build\exploded-aar\com.google.android.gms\play-services\4.3.23\res\drawable-hdpi\common_signin_btn_text_focus_light.9.png -o C:\Users\ashokp\Desktop\Studio\AndroidV2SDK_AndroidStudioFormat\Google Play Services\SampleApplication\AndroidV2SDKSampleApp_GooglePlayServices\app\build\res\all\debug\drawable-hdpi\common_signin_btn_text_focus_light.9.png Error Code: 42 This only happens if the project is saved on the C: drive. If I save it to some other drive, it works perfectly. Does anyone else face this issue? What causes this? How can I fix/circumvent this?

Merge PDF files Posted: 22 May 2022 12:32 AM PDT Is it possible, using Python, to merge separate PDF files? Assuming so, I need to extend this a little further. I am hoping to loop through folders in a directory and repeat this procedure. And I may be pushing my luck, but is it possible to exclude a page that is contained in each of the PDFs (my report generation always creates an extra blank page).
