| Run PHP script after Azure Web app deployment Posted: 17 Jan 2022 02:54 AM PST I am having an Azure app Service and I want to upload/deploy an .php file to it an run it right after the upload. I managed to upload it via curl and also start a post deployment script. Unfortunately I can not use the command "php ..." in it because I get an error like: "/opt/Kudu/Scripts/starter.sh: line 2: exec: php: not found\n" in the logs. The same occurs if I use the "/api/command" endpoint with the same command. I get the same kind of error in the response. It seems like the php executable is not known in that environment. Is there any way to run a php script via the command API or in a post deployment script? Thanks in advance |

| Largest number formed from some or all elements in an array divisible by 3 Posted: 17 Jan 2022 02:53 AM PST I am trying solve the following question: Given an array of digits, what is the largest number divisble by 3 that can be formed using some / all the elements in the array? The question only accepts Java and Python, and I chose Python despite being completely inexperienced with it. I looked around and it seems like the general idea was to kick off the smallest element to get the digits total divisible by 3, and wrote the following "subtractive" approach: def maxdiv3(l): l.sort() tot = 0 for i in l: tot += i if tot % 3 == 0: l.sort(reverse=True) return int(''.join(str(e) for e in l)) elif tot % 3 == 1: cl = [] acl = [] for i in l: if i % 3 == 0: acl.append(i) else: cl.append(i) removed = False nl = [] for i in cl: if not removed: if i % 3 == 1: removed = True else: nl.append(i) else: nl.append(i) if removed: nl.extend(acl) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) else: return 0 else: if len(acl) > 0: acl.sort(reverse=True) return int(''.join(str(e) for e in acl)) return 0 elif tot % 3 == 2: cl = [] acl = [] for i in l: if i % 3 == 0: acl.append(i) else: cl.append(i) removed2 = False nl = [] for i in cl: if not removed2: if i % 3 == 2: removed2 = True else: nl.append(i) else: nl.append(i) if removed2: nl.extend(acl) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) removed1 = 0 nl = [] for i in cl: if removed1 < 2: if i % 3 == 1: removed1 += 1 else: nl.append(i) else: nl.append(i) if removed1 == 2: nl.extend(acl) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) if len(acl) > 0: acl.sort(reverse=True) return int(''.join(str(e) for e in acl)) else: return 0
This approach kept gets stuck on a hidden test case, which means I can't work out what or why. Based on this, I wrote up a new one: def maxdiv3(l): l.sort() l0 = [] l1 = [] l2 = [] for i in l: if i % 3 == 0: l0.append(i) elif i % 3 == 1: l1.append(i) elif i % 3 == 2: l2.append(i) tot = sum(l) nl = [] if tot % 3 == 0: nl = l nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) return 0 elif tot % 3 == 1: if len(l1) > 0: l1.remove(l1[0]) nl.extend(l0) nl.extend(l1) nl.extend(l2) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) return 0 elif len(l2) > 1: l2.remove(l2[0]) l2.remove(l2[0]) nl.extend(l0) nl.extend(l1) nl.extend(l2) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) return 0 else: return 0 elif tot % 3 == 2: if len(l2) > 0: l2.remove(l2[0]) nl.extend(l0) nl.extend(l1) nl.extend(l2) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) return 0 elif len(l1) > 1: l1.remove(l1[0]) l1.remove(l1[0]) nl.extend(l0) nl.extend(l1) nl.extend(l2) nl.sort(reverse=True) if len(nl) > 0: return int(''.join(str(e) for e in nl)) return 0 else: return 0
And this one does pass all the test cases, including the hidden ones. Here are some of the test cases that I ran my attempt through: [3, 9, 5, 2] -> 93 [1, 5, 0, 6, 3, 5, 6] -> 665310 [5, 2] -> 0 [1] -> 0 [2] -> 0 [1, 1] -> 0 [9, 5, 5] -> 9
It seems to me that my attempt and the SO solution had the same idea in mind, so what did I neglect to consider? How is the SO solution different from mine and how does that catch whatever it is that my attempt didn't? Thank you for your time.
A slightly off topic additional question: How do I find edge cases when dealing with blind test cases? I built a random input generator for this question but that didn't help anywhere near I wished it would and is likely not a good general solution. |
| Chrome Extension doesn't work with MV3, getting "Insecure CSP value "'unsafe-eval'" in directive 'script-src'." Posted: 17 Jan 2022 02:53 AM PST I'm trying to make a simple Chrome extension that replaces all images with another one (img.jpg). Main folder - clrimgs.js

| Xamarin swap single ResourceDictionary programmatically Posted: 17 Jan 2022 02:53 AM PST I'm currently trying to get custom themes working with a Xamarin App and I've found a way I can make this work the way I want it to, but it seems terribly inefficient, so figured I'd ask to see if you lot had better answers. So here's the issue, I want to build a screen where users can change themes (there will be many, not just light/dark), and I want to swap out the current theme ResourceDictionary and replace it with the new chosen theme's ResourceDictionary. The problem is I also want the App to have other global ResourceDictionaries, and every tutorial I find recommends calling Resources.MergedDictionaries.Clear(), but that then gets rid of my other ResourceDictionaries. Here is my Xaml, I don't want to replace DefaultButton.xaml or LinkButton.xaml, I only want to replace LightTheme.xaml. <?xml version="1.0" encoding="utf-8" ?> <Application xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="myTestApp.App"> <Application.Resources> <ResourceDictionary Source="Themes/ResourceDictionaries/LightTheme.xaml" /> <ResourceDictionary Source="Styles/DefaultButton.xaml" /> <ResourceDictionary Source="Styles/LinkButton.xaml" /> </Application.Resources> </Application>
Then in my App class I have public void ChangeTheme(ThemeOptions theme) { ResourceDictionary newRes; switch (theme) { case ThemeOptions.Light: newRes = new LightTheme(); break; case ThemeOptions.Dark: newRes = new DarkTheme(); break; default: newRes = new LightTheme(); break; } Resources.MergedDictionaries.Clear(); Resources.Add(newRes); }
Now obviously the DefaultButton.xaml and LinkButton.xaml ResourceDictionaries have now been cleared. I can add them back, but it seems terribly inefficient over just finding and removing the Theme. Is there an easy way to simply identify the ResourceDictionary I want to overwrite and replace that? |

| Is it possible to provide a constuctor with copy elision for member initialization?

| Prediction with calculated coefficients without dataset Posted: 17 Jan 2022 02:53 AM PST Background: I have a DOE-output for 4 responses and 4 factors and I calculated new coefficients (substraction of two functions) to get a new function which I wanna use in the end for visualization and calculations. I tried it with the following code: a <- rep(1,20) b <- rep(1,20) c <- rep(1,20) d <- rep(1,20) y <- rep(1,20) formula<- y~a+b+c+d+a:b+a:c+a:d+b:c+b:d+c:d+I(a^2)+I(b^2)+I(c^2)+I(d^2) fit_predict <- lm(formula) fit_predict$coefficients<-new_coefficients new<-data.frame(a=rep(25,20),b=c(seq(0.1,0.5,length=20)),c=rep(3.5,20),d=c(seq(0.05,1.0,length=20))) pred<-predict(fit_predict, newdata=new) new_prediction <- cbind(new,pred)
The output is always the same as the first coefficient. Order of the coefficients is the same and was not changed. Does anybody have a more robust way or a better way to get the prediction from the calculated formula? |

| predict matrix with machine learning models (classification) Posted: 17 Jan 2022 02:52 AM PST I have 2 dataset which is of shape : X = 3114 x 627 y = 3114 x 1 (species) Each 9 rows (spectras) from X corresponds to 1 strain, thus there is 3114/9 = 346 strains. The goal is to predict the species of each strains. I was wondering what is the best way to predict. Thus, is it possible to predict this way : reshaping the dataset this way : having a matrix with 9 x 627 which predict the species of one strain, thus having 346 (each strains is a 9 x 627 matrix) Or I can just let the dataset as it is and predict that way? |
| Matrix Values to Probabilities with Logistic Regression Posted: 17 Jan 2022 02:53 AM PST I have a Non Negative Matrix Factorization algorithm and I'm calculating the A-hat matrix from it.

Fitting the data to the model and I calculate the R matrix as follow. model = NMF( n_components=100 ) W = model.fit_transform( input_matrix ) H = model.components_ R = np.dot( W, H )
Then I want to calculate the probabilities to this matrix. Currently I can calculate them by normalizing the matrix with the following code row_sums= R.sum(axis=1) probabilities= R / row_sums[:, np.newaxis]
But its not 100% correct way to calculate the probabilities. The correct way is to run a logistic regression algorithm to generate them. How to do that? |

| Fit with convolution Posted: 17 Jan 2022 02:54 AM PST I want to fit experimental data of a time-dependent signal. The signal is the result of a concentration convolved with a pulse. But the question is more general, so I hope the picture below will help. As you see, the values of the convolution drop off at the start and end. This is correct since also the signal drops to zero. However, my experimental data would start on 1 (normalized background) and would rise to some unknown value. But of course, I can only take a finite amount of data. When I now use my fit function, it will also drop off at the start and end, but that is not how it should look like to have a good fit. My solution would be to define the fit function so that it gives a zero where I don't have full overlap of the data and the pulse and modify my experimental data (which are basically lost then) accordingly, i.e. set them at those x-values to zero as well. Since time-resolved measurements need this, I wonder what is the usual way to go about that? Or any other solutions? Convolution of signal and pulse:

| Query with ElasticSearch body using GluonhqConnect.Provider.RestClient Posted: 17 Jan 2022 02:52 AM PST I am trying to use the com.gluonhq.connect.provider.RestClient to query an API that is Elastic Search enabled. Maven: <dependency> <groupId>com.gluonhq</groupId> <artifactId>connect</artifactId> <version>2.0.1</version> </dependency>
I have attempted to make a request using the following: private GluonObservableObject<Item> getData() { RestClient myApiClient = RestClient.create() .method("POST") .host(applicationProperties.getAPIURL()) .path("search") .header("accept", "application/json") .header("Content-type", "application/json") .queryParam("private_key", applicationProperties.getAPIKEY()) .dataString(ITEMREQUEST); return DataProvider.retrieveObject( myApiClient.createObjectDataReader(Item.class)); }
...where the dataString is a json-formatted String representing the body of the request (I can assume the request is correctly formatted because I tested it in Postman and the request returned the expected data). If it helps, here is the request body: { "indexes": "idx1, idx2", "columns": "col1,col2,col3,col4,col5", "body": { "query": { "bool": { "must": [ { "wildcard": { "NameCombined_en": "*" } } ], "filter": [ { "range": { "ID": { "gte": "20000" } } } ] } }, "from": 0, "size": 100 } }
The problem I have is that the (gluon) RestClient and, by extension, the DataProvider.retrieveObject method return exactly...nothing. I'm pretty sure I'm doing something wrong and I'm fairly certain it is the .dataString() method (which requires an "entity"), but I have not found an alternative to use as a way of passing the body into the request. The reasoning behind using the com.gluonhq.connect library is to avoid having to also create my own Observable lists (by hand) - the library automatically spits one out, providing the data is suitably formatted...and present. At least, that's my understanding of it. Can someone point me in the right direction? I have found no indication or explanation of how to do POST requests with this library. UPDATE 20220117 Main.java public class Main extends Application { ApplicationProperties applicationProperties = new ApplicationProperties(); private static final String RESTLIST_VIEW = HOME_VIEW; private static final String RESTOBJECT_VIEW = "RestObjectView"; private final AppManager appManager = AppManager.initialize(this::postInit); @Override public void init() { appManager.addViewFactory(RESTOBJECT_VIEW, () -> new RestObjectView(applicationProperties.APIURL, applicationProperties.APIKEY)); updateDrawer(); } @Override public void start(Stage stage) { appManager.start(stage); } private void postInit(Scene scene) { Swatch.BLUE.assignTo(scene); ((Stage) scene.getWindow()).getIcons().add(new Image(Objects.requireNonNull(Main.class.getResourceAsStream("/icon.png")))); } private void updateDrawer() { NavigationDrawer navigationDrawer = appManager.getDrawer(); NavigationDrawer.Header header = new NavigationDrawer.Header("Gluon Mobile", "Gluon Connect Rest Provider Sample", new Avatar(21, new Image(getClass().getResourceAsStream("/icon.png")))); navigationDrawer.setHeader(header); NavigationDrawer.Item listItem = new NavigationDrawer.Item("List Viewer", MaterialDesignIcon.VIEW_LIST.graphic()); NavigationDrawer.Item objectItem = new NavigationDrawer.Item("Object Viewer", MaterialDesignIcon.INSERT_DRIVE_FILE.graphic()); navigationDrawer.getItems().addAll(listItem, objectItem); navigationDrawer.selectedItemProperty().addListener((obs, oldItem, newItem) -> { if (newItem.equals(listItem)) { appManager.switchView(RESTLIST_VIEW); } else if (newItem.equals(objectItem)) { appManager.switchView(RESTOBJECT_VIEW); } }); } public static void main(String[] args) { System.setProperty("javafx.platform", "Desktop"); launch(args); }

| How to upsample a multi-index dataframe ensuring each grouping covers the same time range (provide custom starting and ending datetimes) Posted: 17 Jan 2022 02:54 AM PST Here is a dummy example to illustrate the problem. I am interested in upsampling to the beginning of the each year (AS) and, for every country, I want to cover the period that goes from 1995 to the year 2000. Imagine we had the following dataset: df = pd.DataFrame({ 'year': [ '1995-01-01', '1997-01-01', '1997-01-01', '1998-01-01', '2000-01-01', '1996-01-01', '1999-01-01', ], 'country': [ 'ES', 'ES', 'GB', 'GB', 'GB', 'DE', 'DE', ], 'members': [ 100, 101, 200, 201, 202, 300, 301, ] }) df['year']= pd.to_datetime(df['year']) df = df.set_index(['country', 'year']) print(df)
members country year ES 1995-01-01 100 1997-01-01 101 GB 1997-01-01 200 1998-01-01 201 2000-01-01 202 DE 1996-01-01 300 1999-01-01 301
As you can see, no country has data available for all the years between 1995 to 2000. Notice that some countries are also missing the year 1995 and other are missing the year 2000. I know how to upsample the dataframe so that, for each country, it fills the years missing in between (e.g. adds the year 1996 to Spain). def my_upsample(df): return ( df .reset_index('country') # upsampling multi-index wit the keyword level is not supported .groupby('country', group_keys=False) # hence this little trick of single-indexing & grouping # see this issue for details: https://github.com/pandas-dev/pandas/issues/28313 .resample('AS') # resample to the beggining of each year .apply({ 'country':'pad', # pad the countries 'members':'asfreq', # but leave the number of members as NaN. Irrelevant in this dummy example, but # the desired behaviour in my real-world problem }) ) print(my_upsample(df))
country members year 1996-01-01 DE 300.0 1997-01-01 DE NaN 1998-01-01 DE NaN 1999-01-01 DE 301.0 1995-01-01 ES 100.0 1996-01-01 ES NaN 1997-01-01 ES 101.0 1997-01-01 GB 200.0 1998-01-01 GB 201.0 1999-01-01 GB NaN 2000-01-01 GB 202.0
But what I would like to do is make sure that all the countries cover the period from 1995 to 2000. The desired output should look like this: country members year 1995-01-01 DE NaN 1996-01-01 DE 300.0 1997-01-01 DE NaN 1998-01-01 DE NaN 1999-01-01 DE 301.0 2000-01-01 DE NaN 1995-01-01 ES 100.0 1996-01-01 ES NaN 1997-01-01 ES 101.0 1998-01-01 ES NaN 1999-01-01 ES NaN 2000-01-01 ES NaN 1995-01-01 GB NaN 1996-01-01 GB NaN 1997-01-01 GB 200.0 1998-01-01 GB 201.0 1999-01-01 GB NaN 2000-01-01 GB 202.0
I could use python loops iterating over each country and adding the missing rows (see code below), but I would like to know what is the pandas way of achieving this? for country in df.index.levels[0]: if not (country, '1995-01-01') in df.query(f"country == @country").index: # if this country doesn't have the year 1995 create the row with NaN as value df.loc[(country, '1995-01-01'),:] = np.nan if not (country, '2000-01-01') in df.query(f"country == @country").index: # if this country doesn't have the year 2000 create the row with NaN as value df.loc[(country, '2000-01-01'),:] = np.nan print(df.sort_index())
members country year DE 1995-01-01 NaN 1996-01-01 300.0 1999-01-01 301.0 2000-01-01 NaN ES 1995-01-01 100.0 1997-01-01 101.0 2000-01-01 NaN GB 1995-01-01 NaN 1997-01-01 200.0 1998-01-01 201.0 2000-01-01 202.0
And then running my_upsample returns the desired output: print(my_upsample(df.sort_index()))
country members year 1995-01-01 DE NaN 1996-01-01 DE 300.0 1997-01-01 DE NaN 1998-01-01 DE NaN 1999-01-01 DE 301.0 2000-01-01 DE NaN 1995-01-01 ES 100.0 1996-01-01 ES NaN 1997-01-01 ES 101.0 1998-01-01 ES NaN 1999-01-01 ES NaN 2000-01-01 ES NaN 1995-01-01 GB NaN 1996-01-01 GB NaN 1997-01-01 GB 200.0 1998-01-01 GB 201.0 1999-01-01 GB NaN 2000-01-01 GB 202.0

| Why has GitLab saved one folder of my project as a Subproject commit? Posted: 17 Jan 2022 02:53 AM PST I have started developing a website, saved in my local folders, and I am trying to save it to a GitLab repository. I created a new repository on GitLab and then did the following: cd existing_folder git init --initial-branch=main git remote add origin https://gitlab.com/... git add . git commit -m "Initial commit" git push -u origin main
The project comprises two folders, Server and Client, the Client is a React App. However the Client folder is appearing as a red folder icon that can't be opened: 
When I click on the initial commit it says that Client has been added as a Subproject commit: 
I don't know what this means, I have built websites with a similar structure before and Gitlab has not done this. I just want the contents of both Client and Server folders to be saved in the repo. |
| Error "the JAVA_HOME environment variable is not defined correctly" on running "mvn clean javadoc:jar package" Posted: 17 Jan 2022 02:53 AM PST When I try to execute the command mvn clean javadoc:jar package
it shows the JAVA_HOME environment variable is not defined correctly. This environment variable is needed to run this program. NB: JAVA_HOME should point to a JDK, not a JRE. I checked out the already asked question Unable to find javadoc command - maven and the solution I tried above were taken from this solution only. I am new to Ubuntu. How can I fix this? Whereas when I run echo $JAVA_HOME it prints: /usr/lib/jvm/java-11-openjdk-amd64
I also tried setting the JAVA_HOME to: /etc/launchd.conf/java-11-openjdk-amd64/usr/libexec/java-11-openjdk-amd64/usr/libexec/java-11-openjdk-amd64/ When I run mvn -v, it prints: Apache Maven 3.6.3 Maven home: /usr/share/maven Java version: 11.0.10, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64 Default locale: en_IN, platform encoding: UTF-8 OS name: "linux", version: "5.8.0-45-generic", arch: "amd64", family: "unix"
And when I run echo $JAVA_HOME it prints: /usr/lib/jvm/java-11-openjdk-amd64
