| Do duplicate values in the JOIN key affect the result returned? Posted: 04 Jun 2021 08:00 AM PDT I have 2 queries that looks like this. QUERY 1 SELECT a.utype, DATE_TRUNC(b.date, DAY) AS date, (b.noofspec) FROM table1as a JOIN table2 as b ON a.joinkey = b.joinkey
GROUP BY 1, 2, 3 ORDER BY 2; QUERY 2 SELECT a.utype, DATE_TRUNC(b.date, DAY) AS date, SUM(b.noofspec) FROM table1as a JOIN table2 as b ON a.joinkey = b.joinkey
GROUP BY 1, 2, 3 ORDER BY 2; I am expecting that (b.noofspec) of QUERY 1 would somehow have a TOTAL with same value as SUM((b.noofspec). However, it returned a completely different value. My table looks like this Table B Table A After the second query, I know that the first one is not correct too. How should I go around it?  |
| Xarray open_mfdataset is very slow Posted: 04 Jun 2021 08:00 AM PDT Xarray open_mfdataset is a fantastic tool, but I haven't been able to make it work efficiently.

| MySqlPool quarkus reactive client doesn't autoclose Posted: 04 Jun 2021 08:00 AM PDT I am using quarkus-narayana-jta for transaction management and using reactive MysqlPool to insert into db. MysqlPool class is not Autoclosable so do we need to explicitly call close() method from Pool class to close in case failure occurs or is it fine to just print the error message to the log and let transaction manager rollback the entire transaction in case failure occurs.

| Best Node package for recording/playing back http interactions for cucumber testing? [closed] Posted: 04 Jun 2021 08:00 AM PDT I have a Node/React SPA which makes requests to a rails api to load the data. I wrote cucumber js feature tests for the ui which rely on axios requests made to the api. I'd like to be able to record the http interactions so the tests can be run without having to have an instance of the api running. Basically looking for a node equivalent to the ruby vcr gem. I've looked into projects such as vcr.js, yakbak, node-replay, and nock, but none seem to do what I'm looking for. I need something that doesn't run as a separate service like yakbak, and something that allows you to record the interactions and play them back rather than specifying the expected response like in nock. Node-replay looks to be what I want but it doesn't seem to detect http requests made in the react code. Am I missing something with one of these libraries? Or is there another way of doing this? Any suggestions are greatly appreciated! Thank you!  |

| Css fit children elements to parent height Posted: 04 Jun 2021 08:01 AM PDT I want to create a profile-like page. The contents would be like: <profile_entry_name> |<textfield_to_edit_entry>|
So I have something like this: <div className="row"> <p>First name</p> <TextField variant="outlined" /> </div>
To make everything appear on the same line I did: .row { display: flex; flex-direction: row; height: 20px; }
The height: 20px; is key here. It doesn't have to be 20px, I put this value to check if it works properly. The problem is: - even the paragraph doesn't respect its parent
height param - it appears below - the textfield behaves the same way
It looks like this: 
Can I somehow change this behavior? I want those to be of equal height (specified by the parent), because I will have many rows like this and I want them to look nice. P.S TextField is a MUI component, but it doesn't really matter I guess, I can style it as well, maybe just by using !important on some css props.  |

| How to call different Flutter functions based on firebase querySnapshot result Posted: 04 Jun 2021 08:00 AM PDT Using Flutter, I would like to search a Firebase collection (Collection X) to find out if a field (Field Y) exists in any document in said collection. If the document containing the field exists I would like to perform a task ( Task A ), If a document containing the field doesn't exist I would like to perform a different task ( Task B). Here's what I've tried: final CollectionReference collectionXRef = FirebaseFirestore.instance.collection("Collection X") collectionXRef.where("Field Y", isEqualTo: Z) .get().then((QuerySnapshot querySnapshot) { if (querySnapshot.docs.length > 0) { Task A } else { Task B } })
The issue I'm having is that no matter what I put in the If statement: (querySnapshot.docs.length > 0) The code keeps performing Task A Here's what I've tried: if (querySnapshot.docs.isEmpty) if (querySnapshot.docs.isNotEmpty) if (querySnapshot.docs.length > 0) if (querySnapshot.docs.length != 0) if (querySnapshot.size > 0) if (querySnapshot.size != 0) if (querySnapshot.size == 0) if (querySnapshot.size >= 1)
The problem is: I am trying to perform "Task B" if there is no document In the collection that contains the searched field, however, the function always returns Task A, which work fine if there are results to display, but, If there aren't any results it shows a blank results page instead of performing Task B.  |

| Using Vulkan to sample from Android Camera2 hardware buffer - Issue with image formats Posted: 04 Jun 2021 08:01 AM PDT I'm currently working on an app in C++ using the Android ndk, and I need to create a sampler to access the camera output image. I have done this using the AIMAGE_FORMAT_YUV_420_888, and using the VkSamplerYcbcrConversion for accessing the image in the hardware buffer. I do the yuv -> rgb conversion in a shader, and it all looks good on my phone. I have since discovered that this doesn't work on Samsung phones, in my case specifically the Samsung Galaxy S10/S10+. The reason is that when I set up an image reader with the AIMAGE_FORMAT_YUV_420_888 I get a camera error using Samsung. On my OnePlus and on another phone I tried the pipeline worked entirely as expected. I created a very simple test setup to even try to open the camera with that image format in the ImageReader on Samsung S10 and got the error, but when I changed the ImageReader format to AIMAGE_FORMAT_JPEG the error went away and the camera seemed to start as expected. AImageReader* SimpleCamera::CreateJpegReader() { AImageReader* reader = nullptr; // media_status_t status = AImageReader_new(640, 480, AIMAGE_FORMAT_JPEG, //AIMAGE_FORMAT_RGBA_8888 //media_status_t status = AImageReader_new(640, 480, AIMAGE_FORMAT_RGB_565,4, &reader); media_status_t status = AImageReader_newWithUsage(640, 480, //AIMAGE_FORMAT_RGBA_8888, //AIMAGE_FORMAT_RGB_565, //AIMAGE_FORMAT_RGB_888, AIMAGE_FORMAT_JPEG, AHARDWAREBUFFER_USAGE_GPU_SAMPLED_IMAGE | AHARDWAREBUFFER_USAGE_CPU_READ_RARELY, 4, &reader); if (status != AMEDIA_OK) { LOGE("Couldn't create new image reader"); return nullptr; } AImageReader_ImageListener listener{ .context = nullptr, .onImageAvailable = imageCallback1, }; AImageReader_setImageListener(reader, &listener); return reader; }
None of the other formats are guaranteed to be supported except AIMAGE_FORMAT_JPEG, but this format doesn't seem to work with the VkSamplerYcbcrConversion because the image layout is different. Has anyone come up against this issue before? And if so how did you resolve it? At a high level th goal is: In C++, get the image out of the camera2 api and onto a VkImage. If anyone knows an alternative way of doing that, I'm also all ears.  |

| How do I calculate the maximum scroll value RichTextBox? Posted: 04 Jun 2021 08:01 AM PDT There is a RichTextBox with scrollbars disabled. Tried to find out the maximum scroll, using: - GetScrollPos - returns 0;
- GetScrollPosInfo - returns 0;
- GetScrollRange - returns 100;
- https://techarks.ru/qa/csharp/poluchit-polosu-prokrutki-q-I4/ - allows you to know only the pitch (px), if you scroll to the end will show the maximum, if you want to know it in the beginning - nothing (requires scrolling to the end);
float heightLine = targetCtrl.Font.GetHeight() / 3; Maximum = (int)Math.Ceiling(targetCtrl.GetPreferredSize(targetCtrl.Size).Height - targetCtrl.Height + heightLine); - at the beginning the maximum is correct, but as you add or change the size of the elements you get a value that is smaller than the real maximum.  |

| Traefik 2 Dashboard Custom Context Path Posted: 04 Jun 2021 08:00 AM PDT I would like to change the context path for the Traefik dashboard from e.g. https://apps.example.com/ to https://apps.example.com/traefik, as I have Heimdall routed to https://apps.example.com/. All the examples I could find are for Traefik 1.x. What would be the easiest way to do this? My current config (which doesn't work): traefik.toml: [entryPoints] [entryPoints.web] address = ":80" [entryPoints.web.http.redirections.entryPoint] to = "websecure" scheme = "https" [entryPoints.websecure] address = ":443" [api] dashboard = true insecure = true [log] level = "DEBUG" [certificatesResolvers.cloudflare.acme] email = "email@email.com" storage = "acme.json" [certificatesResolvers.cloudflare.acme.dnsChallenge] provider = "cloudflare" resolvers = ["1.1.1.1:53", "8.8.8.8:53"] [providers.docker] watch = true network = "web" exposedByDefault = false endpoint = "unix:///var/run/docker.sock" [providers.file] filename = "traefik_dynamic.toml"
traefik_dynami.toml: [http.routers.api] rule = "Host(`apps.example.com`) && Path(`/traefik`)" entrypoints = ["websecure"] service = "api@internal" [http.routers.api.tls] certResolver = "cloudflare"

| External Script breaks Angular 7 navigation Posted: 04 Jun 2021 08:00 AM PDT I have a standard Angular 7 site with lazy loading in place. The app is in PROD without any issues. Now I'm integrating an external script which loads a chatbot on the site. According to their documentation I only have to add a piece of HTML within the HEAD tag and all should work. The thing is the chat itself works however the angular navigation is broken in terms of having to click twice to an item in the navbar to actual go to the desired route (although when you first click the URL changes). It's weird and I have never come across this before so I was wondering whether Angular exposes any kind of special debugging or something like that for the routing process - note that I have enableTracing set to true and according to those logs the apps works fine but like I said, the view is rendered when you click on the second time as well as the styles applied to things like routerLinkActive etc. Any ideas of what could be going on? I don't know how the JS file could be interacting with the actual Angular routing process. Many thanks in advance!  |
| Is there a 256-bit integer type? Posted: 04 Jun 2021 08:00 AM PDT OS: Linux (Debian 10) CC: GCC 8.3 CPU: i7-5775C There is a unsigned __int128/__int128 in GCC, but is there any way to have a uint256_t/int256_t in GCC? I have read of a __m256i which seems to be from Intel. Is there any header that I can include to get it? Is it as usable as a hypothetic unsigned __int256? I mean if you can assign from/to it, compare them, bitwise operations, etc. What is its signed equivalent (if any)?
EDIT 1: I achieved this: #include <immintrin.h> typedef __m256i uint256_t;
and compiled. If I can do some operations with it, I'll update it here.
EDIT 2: Issues found: uint256_t m; int l = 5; m = ~((uint256_t)1 << l);
ouput: error: can't convert a value of type 'int' to vector type '__vector(4) long long int' which has different size m = ~((uint256_t)1 << l);

| Properly draw text using GraphicsPath Posted: 04 Jun 2021 08:00 AM PDT As you can see in the image below, the text on the PictureBox is different from the one in the TextBox. It is working alright if I use Graphics.DrawString() but when I use the Graphics Path, it truncates and doesn't show the whole text. What do you think is wrong in my code? 
Here is my code: public LayerClass DrawString(LayerClass.Type _text, string text, RectangleF rect, Font _fontStyle, PaintEventArgs e) { using (StringFormat string_format = new StringFormat()) { rect.Size = e.Graphics.MeasureString(text, _fontStyle); rect.Location = new PointF(Shape.center.X - (rect.Width / 2), Shape.center.Y - (rect.Height / 2)); if(isOutlinedOrSolid) { using (GraphicsPath path = new GraphicsPath()) { path.AddString(text, _fontStyle.FontFamily, (int)_fontStyle.Style, rect.Size.Height, rect, string_format); e.Graphics.SmoothingMode = SmoothingMode.AntiAlias; e.Graphics.CompositingQuality = CompositingQuality.HighQuality; e.Graphics.CompositingMode = CompositingMode.SourceOver; e.Graphics.DrawPath(new Pen(Color.Red, 1), path); } } else { e.Graphics.SmoothingMode = SmoothingMode.AntiAlias; e.Graphics.CompositingQuality = CompositingQuality.HighQuality; e.Graphics.CompositingMode = CompositingMode.SourceOver; e.Graphics.DrawString(text,_fontStyle,Brushes.Red, rect.Location); } } this._Text = text; this._TextRect = rect; return new LayerClass(_text, this, text, rect); }

| Getting messages in chat history to display in messenger Pubnub Posted: 04 Jun 2021 08:01 AM PDT I have come to post this question after 2 days of torture not being able to understand how I can actually publish the historic messages stored on my pubnub storage account. To try and understand it at its most basic I have made a chat app and used the history function as described in the SDK but still every time I refresh the page the messages are lost. I have tried the backfill and the restore attributes in subscribe with no luck. All I want to do is click refresh on chrome and see the messages still there. <div><input id=input placeholder=you-chat-here /></div> Chat Output <div id=box></div> <script src="https://cdn.pubnub.com/sdk/javascript/pubnub.4.4.0.min.js"></script> <script>(function(){ var pubnub = new PubNub({ publishKey : 'demo', subscribeKey : 'demo' }); function $(id) { return document.getElementById(id); } var box = $('box'), input = $('input'), channel = 'chat'; pubnub.addListener({ message: function(obj) { box.innerHTML = (''+obj.message).replace( /[<>]/g, '' ) + '<br>' + box.innerHTML }}); pubnub.history({ channel: 'chat', reverse: true, // Setting to true will traverse the time line in reverse starting with the oldest message first. count: 100, // how many items to fetch callback : function(msgs) { pubnub.each( msgs[0], chat ); } }, function (status, response) { // handle status, response console.log("messages successfully retreived") }); pubnub.subscribe({channels:[channel], restore: true, backfill: true, ssl: true}); input.addEventListener('keyup', function(e) { if ((e.keyCode || e.charCode) === 13) { pubnub.publish({channel : channel, message : input.value,x : (input.value='')}); } }); })(); </script> </body>
