| How to check if Google ReCaptcha is v2 or v3 on Server Side Posted: 01 Apr 2021 12:29 PM PDT I have a Web API that receives google recaptcha response and site key for server side verification on authentication. I'd like to validate the version of recaptcha used to store this param as local statistic. There are a lot of different sites connecting to my API, so I want to store used version (v2 or v3) of Google ReCaptcha. Is there any way? I would not like to create different routes or ask then to tell me by a parameter. Once it may not be true or both routes could be used by any version.  |
| How to write an ImmutableList<Number> to a file? Posted: 01 Apr 2021 12:29 PM PDT This should be pretty simple, but it takes about a minute to write about 40 MB. There's got to be a better way. I imagine there's a lot of hangup on casting the Number to a double, but I'm not sure if that's where the problem lies. What's the fastest way to write an ImmutableList<Number> to a binary file of doubles? public static void multiDoubleToImgFastForSO(String outFilename, ImmutableList<ImmutableList<Number>> arrays) { FileOutputStream fos = null; DataOutputStream dos = null; try { fos = new FileOutputStream(outFilename); dos = new DataOutputStream(fos); for (ImmutableList<Number> array : arrays) { for (Number number : array) { dos.writeDouble(number.doubleValue()); } } dos.close(); fos.close(); } catch(Exception e) { e.printStackTrace(); } }

| User defined function for extracting gender from string excel data Posted: 01 Apr 2021 12:28 PM PDT I have an excel file with 100,000 rows of patient data including one column that contains patient information in a descriptive text. This text contains gender information as 'male' and 'female'. Some text does not have any gender information. For this I am interested in obtaining an 'na'. I am trying to use a python user defined function for this data to extract gender by integrating python and excel using xlwings. I wrote the following function which works within Thonny shell for python. import xlwings as xw import regex as re @xw.func def gender(x): if re.search(r'\bfemale\b',x): print('female') elif re.search(r'\bmale\b',x): print('male') else: print('na')
But when I use it in excel, it gives me #NAME? error. I have the excel workbook and python files in the same folder with the same names without any '-' in the names. The import functions work for xlwings and I can run other sample functions. I removed extra spaces from all strings using vba code for replacing vbLf. I am not sure what I am doing wrong. Please let me know if you need more information. Thanks  |
| How to get layer execution time on an AI model saved as .pth file? Posted: 01 Apr 2021 12:28 PM PDT I'm trying to run a Resnet-like image classification model on a CPU, and want to know the breakdown of time it takes to run each layer of the model. The issue I'm facing is the github link https://github.com/facebookresearch/semi-supervised-ImageNet1K-models has the model saved as a .pth file. It is very large (100s of MB), and I don't know exactly how it differs from pytorch except it's binary. I load the model from this file using the following script. But I don't see a way to modify the model or insert the t = time.time() variables/statements in between model layers to break down the time in each layer. Questions: Would running the model in the following script give a correct estimate of end-to-end time (t2-t1) it takes to run the model on the CPU, or would it also include pytorch compilation time? How to insert time statements between consecutive layers to get a breakdown? There is no inference/training script at the github link and only has the .pth file. So how exactly is one supposed to run inference or training? How to insert additional layers between consecutive layers of the .pth model and save them? #!/usr/bin/env python import torch torchvision time model=torch.hub.load('facebookresearch/semi-supervised-ImageNet1K-models', 'resnext50_32x4d_swsl', force_reload=False) in = torch.randn(1, 3, 224, 224) t1 = time.time() out = model.forward(in) t2 = time.time() ```**strong text**

| Regular expression to validate a name Posted: 01 Apr 2021 12:29 PM PDT I'm trying to create a regex that satisfies the following: - The length of the name should be between 2 and 30 characters (both inclusive)
- The name can contain only alphabets and spaces
- The first character of each word of the name should be an upper case alphabet
- Each word should be separated by a space
- The name should not start or end with a space
- Special characters should not be allowed
Here's what I got so far: ^[A-Z][a-zA-z ]{1,29}$
If I put a [^ ] at the end, it allows a special character.  |

| HTML multi-file input to get directory Posted: 01 Apr 2021 12:29 PM PDT I have this HTML input field: <input name="folderInput" type="file" id="folderInput" webkitdirectory directory multiple onchange="selectFolder();" />
It's a folder input, where you can select a folder and the code can get the files. But when I get the files on a function, it returns me the full path of every file. Actual behaviour (example) If the user introduced: - folder called
foo which contains a file text.txt - and a folder called

| 'LiveData' requires that 'User' inherit from 'LiveObject' Posted: 01 Apr 2021 12:28 PM PDT My project uses Swift 5.1 and I am experiencing difficulties running my unit tests with some Swift generics. I have the code below with some type aliases and functions: final class User: LiveObject { //... }
func loadAllUsers(_ database: Database) -> LiveData<User> { database.objects(User.self) }
Database: typealias Object = LiveObject func objects<T>(_ type: T.Type) -> LiveData<T> where T: Object { realm.objects(type) }
LiveData and LiveObject are type aliases or extension of Realms types:
public typealias LiveData<T> = RealmSwift.Results<T> where T: LiveObject //[1. Requirement specified as 'T' : 'LiveObject' [with T = User]] public typealias LiveList<T> = RealmSwift.List<T> where T: LiveObject open class LiveObject: RealmSwift.Object { //... }
But when calling the code below: let users: LiveData<User> = loadAllUsers(database)
I get this error: 'LiveData' requires that 'User' inherit from 'LiveObject'. I really don't know what is happening, the code compiles fine the main application, the problem only happens when I run the XCTest. All the functions above are also called in the main application. I don't understand why the compiler cannot detect that User inherits LiveObject` when running the XCTest. Error log: 
I believe it's a problem with overloaded functions and objc. Is that correct? Edit 1: Removing the types from the function sorted most of the issues (but why?). Thanks!  |

Now I want to get the data to send a daily rate notification for each customer corresponding to nationCode of them with a text form like this: Exchange rate: 1 JPY = {noti}exchangeRate{noti} {noti}varNotiCCYTo{noti}.
And I expected Customer 0000001 Exchange rate: 1 JPY = 0.1 VND.
Customer 0000002 Exchange rate: 1 JPY = 0.3 CNY.
I have store procedure to get data from tables I have mentioned above DELIMITER $$ USE `gojp`$$ CREATE PROCEDURE `NotiGetExchangeRateEveryDay`() DECLARE varNotiBODY nVarchar (9000); DECLARE varNotiCCYTo nvarchar(3); DECLARE varNotiExchangeRate Numeric (30,2); ########################### #IMPORTANT: when I call this procedure, it responses #Error Code: 1172. Result consisted of more than one row #I think problem in this query: *select ex.ccyTo, ex.rate into varNotiCCYTo, varNotiExchangeRate from CUSTOMER cus inner join SYSTEM_NATION sys on cus.nationCode= sys.nationCode inner join EXCHANGE_RATE ex on ex.ccyTo = sys.ccy;* ########################## set varNotiBODY = (SELECT REPLACE(varNotiBODY, '{noti}exchangeRate{noti}', ifnull(varNotiExchangeRate,'')) from dual); set varNotiBODY = (SELECT REPLACE(varNotiBODY, '{noti}varNotiCCYTo{noti}', ifnull(varNotiCCYTo,'')) from dual); After that I want to insert all this table to get list of notification was sent. INSERT INTO `gojp`.`NOTIFICATION_QUEUE` (`customerCode`, `deviceID`, `ntfBody`, `createdDate` ) select noti.customerCode, noti.tokenId, varNotiBODY, now() from NOTIFICATION_TOKEN noti inner join CUSTOMER cus on noti.customerCode = cus.customerCode; END$$ DELIMITER ;
I want to get data about exchange rate of each customer then replace into {noti}exchangeRate{noti}. However, it returns multiple results so I cannot insert into only one param. So, anyone can give me a solution for this?  |
| Pandas new column using a existing column and a dictionary Posted: 01 Apr 2021 12:28 PM PDT I have a data frame that looks like: df = pd.DataFrame({"user_id" : ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'], "score" : [0, 100, 50, 0, 25, 50, 100, 0, 7, 20], "valval" : ["va2.3", "va1.1", "va2.1", "va2.2", "va1.2", "va1.1", "va2.1", "va1.2", "va1.2", "va1.3"]})
print(df)
| user_id | score | valval -------------------------------- 0 | a | 0 | va2.3 1 | b | 100 | va1.1 2 | c | 50 | va2.1 3 | d | 0 | va2.2 4 | e | 25 | va1.2 5 | f | 50 | va1.1 6 | g | 100 | va2.1 7 | h | 0 | va1.2 8 | i | 7 | va1.2 9 | j | 20 | va1.3
I also have a dictionary that looks like: dic_t = { "key1" : ["va1.1", "va1.2", "va1.3"], "key2" : ["va2.1", "va2.2", "va2.3"]}
I whant a new column "keykey".
This column´s values have the key of the dictionary of their correponding value. The result would look something like this: | user_id | score | valval | keykey ---------------------------------------- 0 | a | 0 | va2.3 | key2 1 | b | 100 | va1.1 | key1 2 | c | 50 | va2.1 | key2 3 | d | 0 | va2.2 | key2 4 | e | 25 | va1.2 | key1 5 | f | 50 | va1.1 | key1 6 | g | 100 | va2.1 | key2 7 | h | 0 | va1.2 | key1 8 | i | 7 | va1.2 | key1 9 | j | 20 | va1.3 | key1

| Increase the lock timeout with sqlite, and what is the default values? Posted: 01 Apr 2021 12:27 PM PDT Well known issue when many clients query on a sqlite database : database is locked
I would like to inclease the delay to wait (in ms) for lock release on linux, to get rid of this error. From sqlite-command, I can use for example (4 sec): sqlite> .timeout 4000 sqlite>
I've started many processes which make select/insert/delete, and if I don't set this value with sqlite-command, I sometimes get : sqlite> select * from items where code like '%30'; Error: database is locked sqlite>
So what is the default value for .timeout ? In Perl 5.10 programs, I also get sometimes this error, despite the default value seems to be 30.000 (so 30 sec, not documented).
Did programs actually waited for 30 sec before this error ? If yes, this seems crasy, there is at least a little moment where the database is free even if many other processes are running on this database my $dbh = DBI->connect($database,"","") or die "cannot connect $DBI::errstr"; my $to = $dbh->sqlite_busy_timeout(); # $to get the value 30000
Thanks!  |
| Add leading zeroes in custom function in Google Apps Script Posted: 01 Apr 2021 12:27 PM PDT I'd like to create a custom function that does the same thing as Text(A1,"0000000"), but I have to do it in Google Apps Script because it will be incorporated into a more complicated custom function. Could anybody show me the correct way? Here is what I've been trying, and some derivations thereof: `/** * Sets custom format as "0000000" * * @param {number} input The value to format. * @return The input set to the new custom format * @customfunction */ function to_16ths(input) { var n = input.setNumberFormat("0000000"); return n; }

| React Router Routing three levels deep, Only works in App.js file Posted: 01 Apr 2021 12:28 PM PDT I am building a website with the following link structure: /blog/blog/post1/preview The /blog url lists all the blog posts, the /blog/post1 shows the post in edit view and the preview button in the same edit view links to /preview url that shows the preview of the edited version. My initial idea was to use a /blog/post1/preview url but with the use of <Switch> it became complicated. It did not work because of the whole exact issue where I had to correctly match three urls that start with the same address. So I switched to /preview. Now, I can get the first to urls working but the /preview renders nothing on the screen. Is it because of where my <Link> and <Route> are defined in my app. I have following structure: <Switch> <Route path='/blog'> <Blog/> </Route> <Switch>
in the main app.js
<Route exact path='/blog'> //div with some helper views like search bar </Route> //it is inside map function that renders a card view of many posts, post1 for simplicity <Route path='/blog/post1'> <PostEditor/> </Route>
in the main Post.js component
<Route path='/preview'> //Content </Route>
in the main PostEditor.js The PostEditor.js has the Link and Route tags in the same file but not others. Is it a reason that it renders nothing. When I move the Route tag from PostEditor, to App.js, everything works. Is it a nesting issue or something like that. I tried searching online but did not have much luck with multiple levels of nesting, usually it is two. Any help is greatly appreciated.
I am using react-router 5.2.0 and HashRouter as it works better with github
Update: I have added a sample sandbox to mimic my scenario. Why is the /preview link not rendering anything in this case? I would like to know what I am doing wrong in this case, cause I feel there is a knowledge gap about something about react-router that I am missing about creating Links and Routes at different level? Additionally, what would be the best alternative to handle what I am currently doing. Code SandBox  |
| Getting an fatal error when installing python package on EMR notebook: Python.h: No such file or directory Posted: 01 Apr 2021 12:27 PM PDT I need to install ahocorasick package on EMR notebook. But when I call: sc.install_pypi_package("pyahocorasick")

I am getting the similar error when installing as a bootstrap action. If I call: %pip install pyahocorasick
it is installing fine, but I can not import it. I tried this approach: fatal error: Python.h: No such file or directory, python-Levenshtein install But I can not find any way to run sudo from the notebook. Edit: I tried to install gcc on bootstrape stage with the following .sh file called on bootstrape stage: sudo yum -y install gcc sudo pip3 install pyahocorasick --user

| What is the difference between MAUI and Uno Platform? Posted: 01 Apr 2021 12:27 PM PDT I'm a little confused. Can anyone explain exactly what the difference is between the two? When should we use MAUI and when UNO? As I realized, both can run on different platforms, so what is the reason for introducing two different technologies at the same time? Can they run on Windows 7? Or are they just limited to Windows 10? Can my WPF program run on Linux with these two technologies?  |

| How many times a number appears in a numpy array Posted: 01 Apr 2021 12:29 PM PDT I need to find a way to count how many times each number from 0 to 9 appears in a random matrix created using np.random.randint() import numpy as np p = int(input("Length of matrix: ")) m = np.random.randint(0,9,(p,p)) print(m)
For example if length of matrix = 4 - [[3 4 6 5] [3 4 4 3] [4 2 4 8] [6 8 2 7]]
How many times does the number 4 appear? It should return 5.  |
