| in Prometheus, how to ignore a label in a range-vector (rate()) Posted: 20 Jul 2022 06:10 AM PDT i'm using Prometheus. i am trying to get the rate of a counter, no matter which tenant is being processed by the server. for the rate expression i am using: rate(token_generator_http_request_count{bundle="abcd", kubernetes_name="name_abcd"}[1m] this gives me a different value for each of my tenants. now i want to get the overall rate. i tried using: rate(token_generator_http_request_count{bundle="abcd", kubernetes_name="name_abcd"}[1m] without (tenant) i'm getting an error. it seems Prometheus doesn't let using "without" for a range-vector function. is there a way to unify the rate (without creating a new metric which will not set a tenant label at all) thanks |
| How to dynamically bind data to adaptive card template in Java Posted: 20 Jul 2022 06:10 AM PDT I am developing a Microsoft teams bot using java (spring boot) which send the messages to the teams users, I can sent the messages using cards. Now I am trying to dynamically generate the adaptive card. I have created the adaptive card template and I have the data, In adaptive card designer everything work fine. The problem is there is no Java SDK for adaptive card templating, there is only C# and JavaScript SDKs https://docs.microsoft.com/en-us/adaptive-cards/templating/sdk Using JavaScript we can simple pass the data to template to generate the card but how can I do it in java spring boot application. Here is my template: { "$schema": "https://adaptivecards.io/schemas/adaptive-card.json", "type": "AdaptiveCard", "version": "1.3", "body": [ { "id": "messageBlock", "type": "TextBlock", "text": "${msg.message}", "wrap": true }, { "id": "messageSeparator", "type": "TextBlock", "text": " ", "separator": true, "spacing": "Medium" }, { "id": "mediaContainer", "type": "Container", "$data": "${media}", "items": [ { "type": "ColumnSet", "columns": [ { "type": "Column", "width": "auto", "items": [ { "type": "Image", "$when": "${not(empty(icon))}", "url": "${icon}", "size": "Small" } ] }, { "type": "Column", "width": "stretch", "items": [ { "type": "TextBlock", "$when": "${not(empty(fileName))}", "text": "${fileName}", "size": "Medium", "wrap": true, "weight": "Bolder", "color": "Accent", "height": "stretch" } ], "selectAction": { "type": "Action.OpenUrl", "url": "${url}", "title": "View" } } ] }, { "type": "TextBlock", "text": " ", "wrap": true, "separator": true, "spacing": "Medium" } ] } ], "actions": [ { "$when": "${direction == 'Inbound'}", "type": "Action.Submit", "title": "Reply", "data": { "type": "task/fetch", "submitLocation": "task/fetch" } } ]
} and the sample data: { "direction": "Inbound", "message": "test message", "media": [ { "url": "https://example.com/imageUrl1", "icon" : "https://example.com/icon1", "fileName": "file1.png", "fileType": "png" }, { "url": "https://example.com/imageUrl2", "icon" : "https://example.com/icon2", "fileName": "image1.png", "fileType": "png" } ]

| WD Hard disk stopped working while copying a file [closed] Posted: 20 Jul 2022 06:09 AM PDT I recently bought a 2TB hard disk about a month ago. Suddenly today when I was copying a file to it suddenly stopped working and started to make a noise. (It is similar to the noise hard disks make when it starts. But this just spins turning off and spinning again. (or the actuator makes it.. don't know)) So I restarted the PC and the disk was gone from the file explorer so I checked the disk manager. And this was what I greeted with (when I start the PC it made the noise for few mins and settled down) 
I am not sure what should I do... will it erase all the data? There were some important data in that disk. Is there a safe way to fix this. |
| TFTP client error when trying to open the requested file Posted: 20 Jul 2022 06:09 AM PDT i have already posted my question on [NXP comunity forum][1] but the team says that LWIP is open source and not related to NXP. which i agree. i have the following scenario : - PC will run a TFTP server containing all SW files
- MCU will run a TFTP client that will ask (by file name) the server for the flash file
- MCU will receive the flash file and start the SW update (erase all flash memory and write).
for TFTP server i used the [TFTPD64][2] . MCU will run the client, most of the code is taking from this github [repo][3] TFTP client is started correctly on port 69, when i request a file from the server i ge the error 'Failed to open file', even though the server is poiting to it and is available void tftp_example_init_client(void) { void *f; err_t err; ip_addr_t srv; int ret = ipaddr_aton(LWIP_TFTP_EXAMPLE_CLIENT_REMOTEIP, &srv); if(ret != 1) { printf("ipaddr_aton failed \r\n"); } err = tftp_init_client(&tftp); if(err != ERR_OK) { printf("tftp_init_client failed, error : %d \r\n", err); } f = tftp_open_file(LWIP_TFTP_EXAMPLE_CLIENT_FILENAME, 1); if(f == NULL) { printf("failed to open file , %d \r\n", f); } err = tftp_get(f, &srv, TFTP_PORT, LWIP_TFTP_EXAMPLE_CLIENT_FILENAME, TFTP_MODE_OCTET); if(err != ERR_OK) { printf("tftp_get failed \r\n"); }
} the tftp_open_file function is defined as follow : static void * tftp_open_file(const char* fname, u8_t is_write) { snprintf(full_filename, sizeof(full_filename), "%s%s", LWIP_TFTP_EXAMPLE_BASE_DIR, fname); full_filename[sizeof(full_filename)-1] = 0; printf("%s \r\n",fname); if (is_write) { return (void*)fopen(full_filename, "wb"); } else { return (void*)fopen(full_filename, "rb"); } } static void* tftp_open(const char* fname, const char* mode, u8_t is_write) { LWIP_UNUSED_ARG(mode); return tftp_open_file(fname, is_write); }

| Gets all the records from Table A if the id field does not exist in table B and if it exists it is different from the date field - mysql Posted: 20 Jul 2022 06:09 AM PDT I need to get a query from two tables that is conditional. I want to say, I need to obtain the "id_product" field from table A that does not exist in table B, and if it exists in table B it has to be that the "date" field in table A is different from the "date" field in the table B. Table A id_product,date,description... 3, 2022-07-19 4, 2022-07-20 5, 2022-07-20

html, body, #wrapper { height: 100%; width: 100%; } #title { font-size: xx-large; text-align: center; } #word { font-size: xx-large; text-align: center; } .word { display: inline; margin: 2px; background-color: beige; }

It seems to be a simple problem but it's driving me insane. function SetupKeyboard() { letters=document.getElementsByClassName("word"); selectedLetter=document.getElementById("first"); }
I need the selected letter to be the first element of the "letters" array but for some reason selectedLetter=letters[0] gave back "undefined". I tried this approach too and it's the same problem. I am obviously missing something. When I debug the code it works properly and the console logs everything as expected. When NOT in debugger the value of selectedLetter is "undefined". Also, the problem is gone when I call the function manually through browser console as well. I know the problem is not in the DOM not existing because I run it all like this: window.addEventListener('load', ()=>{ GetLink(); SetupKeyboard(); });

| Unable to access/get value of abstract (base) class properties from derived class - TypeScript Posted: 20 Jul 2022 06:09 AM PDT I have 2 classes - one is abstract and another class is extending it. In ABSTRACT class I have some public/protected properties which ARE initialized in constructor. Let it be abstract Parent and Child extends Parent Questions: Why, when I am trying to get value of the properties of abstract class like: super.somePropertyOfParent it is always UNDEFINED, but when I call it like: this.somePropertyOfParent it HAS value? Logically, super constructor is always called first, so these fields should be initialized first of all. I have 2 BehaviourSubjects (countryValue, languageValue) in my Parent abstract class, which are initialized with some 'initial value' in constructor. In Child class in OnInit method (which obviously called after Parent constructor) I am subscribing to Parent's BehaviourSubjects like: this.countryValue.subscribe(...) and it receives the 'INITIAL' value. Then in Parent's class ngOnChange method calls subject.next(...), but Child doesn't receive new value...why? P.S. if make BehaviourSubject properties STATIC and refer to the ClassName.property - everything works fine. Please see code below: @Directive() export abstract class IbCustomElementComponent implements OnChanges{ @Input('data-country') country = ''; @Input('data-language') language = ''; public countryValue:BehaviorSubject<string>; public languageValue:BehaviorSubject<string>; protected constructor(public translateService: TranslateService) { this.countryValue = new BehaviorSubject<string>('initial'); this.languageValue = new BehaviorSubject<string>('initial'); } abstract customElementReady(changes: SimpleChanges): void; ngOnChanges(changes: SimpleChanges) { if (this.country && this.language) { this.translateService.use(this.country.toLocaleLowerCase() + '-' + this.language); this.customElementReady(changes); this.countryValue.next(this.country); this.languageValue.next(this.language); } } }
export class CustomerCardsComponent extends IbCustomElementComponent implements OnInit { displayedColumns: string[] = ['fieldName', 'value']; CARD_DATA: CardData[][] = []; dataSource = this.CARD_DATA; cards: Card[] = []; currentCustomer : Customer = new Customer(); constructor(private customerListService: CustomerListService, public override translateService: TranslateService) { super(translateService); } ngOnInit(): void { this.countryValue.subscribe(c=>{ this.currentCustomer.bic = Bic[c.toUpperCase()]; if(this.currentCustomer.bic){ this.getCustomerCards(this.currentCustomer) } }) } }

| Scrape html table row with Beautiful Soup Posted: 20 Jul 2022 06:09 AM PDT I'm trying to scrape an html table with bs4, but my code is not working. I'd like to get the tds row data information so that I can write them in a csv file. this is my html code: <table class="sc-jAaTju bVEWLO"> <thead> <tr> <td width="10%">Rank</td> <td>Trending Topic</td> <td width="30%">Tweet Volume</td> </tr> </thead> <tbody> <tr> <td>1</td> <td><a href="http:///example.com/search?q=%23One" target="_blank" without="true" rel="noopener noreferrer">#One</a></td> <td>1006.4K tweets</td> </tr> <tr> <td>2</td> <td><a href="http:///example.com/search?q=%23Two" target="_blank" without="true" rel="noopener noreferrer">#Two</a></td> <td>1028.7K tweets</td> </tr> <tr> <td>3</td> <td><a href="http:///example.com/search?q=%23Three" target="_blank" without="true" rel="noopener noreferrer">#Three</a></td> <td>Less than 10K tweets</td> </tr> </tbody> </table>
This is my first try: url = requests.get(f"https://www.exportdata.io/trends/italy/2020-01-01/0") soup = BeautifulSoup(url.text, "html.parser") table = soup.find_all("table", attrs={"class":"sc-jAaTju bVEWLO"})
And my second one: tables = soup.find_all('table') for table in tables: td = tables.td.text.strip()
But neither are working. What am I missing? Thank you |

| Itertools Groupby returns None when appending list to dict Posted: 20 Jul 2022 06:09 AM PDT I have the following code on which I'm grouping by a value in a particular dictionary: from itertools import groupby def group_owners(files): # sort data before using groupby files = dict(sorted(files.items())) # create the groupby which will return an iterator containing a key (string) and a group which itself is a iterator # in order to store this group iterator is necessary to initialize an empty data strcturure first iterator = groupby(files,lambda x: files[x]) groups = [] return {k:groups.append(list(g)) for k,g in iterator} if __name__ == "__main__": files = { 'Input.txt': 'Randy', 'Code.py': 'Stan', 'Input2.txt': 'James', 'Output.txt': 'Randy' } print(group_owners(files))
This code returns me that: {'Stan': None, 'Randy': None, 'James': None}
I was expecting a list in place of None with the groups for each key, in fact when I debug I can see that a list of lists is being created but at the end of program None is returned. I also would like to have only a flat list and not a list of lists. My expected output is: {'Stan': ['Code.py'], 'Randy': ['Input.txt','Output.txt'], 'James': 'Input2.txt'}
If I use instead: {k:list(g) for k,g in iterator} what I get is:
{'Stan': ['Code.py'], 'Randy': ['Output.txt'], 'James': ['Input2.txt']}
I believe because of this fact, quoting form Python docs: The returned group is itself an iterator that shares the underlying iterable with groupby(). Because the source is shared, when the groupby() object is advanced, the previous group is no longer visible. So, if that data is needed later, it should be stored as a list: https://docs.python.org/3/library/itertools.html#itertools.groupby |
| Power BI - Filtering model on latest version of all attributes of all dimensions through DAX Posted: 20 Jul 2022 06:09 AM PDT I have a model that's comprised of multiple tables containing, for every ID, multiple rows with a valid_from and valid_to dates. This model has one table in that is linked to every other table (a table working as both a fact and a dimension). This fact has bi-directional cross filtering with the other tables. I also have a date dimension that is not linked to any other table. I want to be able to calculate the sum of a column in this table in the following way: If a date range is selected, I want to get the sum of the latest value per ID from the fact able that is before the max selected date from the date dimension. If no date is selected, I want to get the sum of the current version of the value per ID. This comes down to selecting the latest value per ID filtered on the dates. Because of the nature of the model (bi-directional with the fact/dimension table), I want to have the latest version of any attribute from any dimension selected in the visual. Here's an data example and the desired outcome: fact/dimension table: | ID | Valid_from | Valid_to | Amount | SK_DIM1 | SK_DIM2 | | 1 | 01-01-2020 | 05-12-2021 | 50 | 1234 | 6787 | | 1 | 05-13-2021 | 07-31-2021 | 100 | 1235 | 6787 | | 1 | 08-01-2021 | 12-25-2021 | 100 | 1236 | 6787 | | 1 | 12-26-2021 | 12-31-2021 | 200 | 1236 | 6787 | | 1 | 01-01-2022 | 12-31-9999 | 200 | 1236 | 6788 | Dimension 1: | ID | SK | Valid_from | Valid_to | Name | | 1 | 1234 | 10-20-2019 | 06-01-2021 | Name 1 | | 1 | 1235 | 06-02-2021 | 07-31-2021 | Name 2 | | 1 | 1236 | 08-01-2021 | 12-31-9999 | Name 3 | Dimension 2: | ID | SK | Valid_from | Valid_to | Name | | 1 | 6787 | 10-20-2019 | 12-31-2021 | Name 1 | | 1 | 6788 | 01-01-2022 | 12-31-9999 | Name 2 | My measure is supposed to do the following: - If no date is selected than the result will be a matrix like the following:
| Dim 1 Name | Dim 2 Name | Amount Measure | | Name 3 | Name 2 | 200 | - If July 2021 is selected than the result will be a matrix like the following:
| Dim 1 Name | Dim 2 Name | Amount Measure | | Name 2 | Name 1 | 100 | So the idea here is that the measure would filter the fact table on the latest valid value in the selected date range, and then the bi-directional relationships will filter the dimensions to get the corresponding version to that row with the max validity (last valid row) in the selected range date. I have tried to do the following two DAX codes but it's not working: Solution 1: With this solution, filtering on other dimensions work and I get the last version in the selected date range for all attributes of all used dimensions. But the problem here is that the max valid from is not calculated per ID, so I only get the max valid from overall. Amount Measure= VAR _maxSelectedDate = MAX(Dates[Dates]) VAR _minSelectedDate = MIN(Dates[Dates]) VAR _maxValidFrom = CALCULATE( MAX(fact[valid_from]), DATESBETWEEN(fact[valid_from], _minSelectedDate, _maxSelectedDate) || DATESBETWEEN(fact[valid_to], _minSelectedDate, _maxSelectedDate) ) RETURN CALCULATE( SUM(fact[Amount]), fact[valid_from] = _maxValidFrom )
Solution 2: With this solution, I do get the right max valid from per ID and the resulting number is correct, but for some reason, when I use other attributes from the dimensions, it duplicates the amount for every version of that attribute. The bi-directional filtering does not work anymore with Solution 2. Amount Measure= VAR _maxSelectedDate = MAX(Dates[Dates]) VAR _minSelectedDate = MIN(Dates[Dates]) VAR _maxValidFromPerID = SUMMARIZE( FILTER( fact, DATESBETWEEN(fact[valid_from], _minSelectedDate, _maxSelectedDate) || DATESBETWEEN(fact[valid_to], _minSelectedDate, _maxSelectedDate) ), fact[ID], "maxValidFrom", MAX(fact[valid_from]) ) RETURN CALCULATE( SUM(fact[Amount]), TREATAS( _maxValidFromPerID, fact[ID], fact[valid_from] ) )
So if somebody can explain why the bi-directional filtering doesn't work anymore that will be great, and also, more importantly, if you have any solution to have both the latest value per ID and still keep filtering on other attributes, that would be great! Sorry for the long post, but I thought it's best to give all the details for a complete understanding of my issue, this has been picking my brain since few days now and I'm sure I'm missing something stupid but I turned to this community for help because I cannot seem to be able to find a solution! Thank you very much in advance for any help! |

| Transform reorder timestamps in dataframe - R Posted: 20 Jul 2022 06:09 AM PDT I have the following table in R: S <- c("A","A","A","B","B","B","C","C","C") TS <- c(1,1,1,2,2,2,3,3,3) f1 <- c(10,20,30,15,25,35,17,27,37) p <- c(100,200,300,150,250,350,170,270,370) df <- data.frame(S, TS, f1, p)

| C++/WinRT: Setting value of DisplayMemberPath in XAML for Combobox Posted: 20 Jul 2022 06:09 AM PDT I want to use a struct as item type of a combobox based on the following code: MyUserControl.idl: namespace my_app { struct Info { String Id; String DisplayName; }; [default_interface] runtimeclass MyUserControl : Microsoft.UI.Xaml.Controls.UserControl { MyUserControl(); } }
MyUserControl.xaml: ... <ComboBox x:Name="cbInfo" DisplayMemberPath="DisplayName"/> ...
MyUserControl.xaml.cpp: void MyUserControl::SetInfo() { ... Info firstInfo = Info(); firstInfo.Id = L"First identifier"; firstInfo.DisplayName = L"First display name"; cbInfo().Items().Append(winrt::box_value(firstInfo) ); Info secondInfo = Info(); secondInfo.Id = L"Second identifier"; secondInfo.DisplayName = L"Second display name"; cbInfo().Items().Append(winrt::box_value(secondInfo) ); ... }
The code compiles and runs, but the items in the combo box are displayed with an empty string. If I omit the attribute DisplayMemberPath in the XAML file, than for each item the following string is displayed: Windows.Foundation.IReference`<my_app.Info> How do I make the DisplayName value of the Info struct appear? Update: To avoid possible problems caused by boxing, I implemented the item type as a Windows Runtime Component for testing purposes: InfoItem.idl: namespace my_app { [default_interface] runtimeclass InfoItem { InfoItem(); String Id; String DisplayName; } }
InfoItem.h: #pragma once namespace winrt::my_app::implementation { struct InfoItem : InfoItem T<InfoItem> { InfoItem() = default; hstring Id(); void Id(hstring const& value); hstring DisplayName(); void DisplayName(hstring const& value); private: hstring mId; hstring mDisplayName; }; } namespace winrt::my_app::factory_implementation { struct InfoItem : InfoItem T<InfoItem, implementation::InfoItem> { }; }
InfoItem.cpp #include "pch.h" #if __has_include("InfoItem.g.cpp") #include "InfoItem.g.cpp"
