I am trying to perform case modification with bash/zsh parameter expansion on macOS (11.4) and making some mistakes. Specifically, I want to take a variable that contains a string and turn it to snakecase (i.e.: from This is a STRING to this_is_a_string). I am taking baby steps and so far I am just trying to turn everything to lowercase and, as far as I understand it, the theory should work like this:

I am attempting to reduce the dimensionality of a categorical feature by extracting an embedding layer from a neural net and using it as an input feature in a separate XGBoost model.

An embedding layer has the dimensions (nr. unique categories + 1, chosen output size). How can it be concatenated to the continuous variables in the original training data with the dimensions (nr. observations, nr. features)?

Below is a reproducible example of regression with a neural net, in which a categorical feature is encoded as a learned embedding layer. The example is closely adapted from: http://machinelearningmechanic.com/keras/2018/03/09/keras-regression-with-categorical-variable-embeddings-md.html#Define-the-input-layers

At the end I have printed the embedding layer and its shape. How can this layer be merged with the continuous features in the original training data (X_train_continuous)? If the number of rows were equal to the number of categories and if we knew the order in which categories are represented in the embedding layer, the embedding array could perhaps be joined to the training observations on category, but instead the number of rows equals the number of categories + 1 (in the code: len(values) + 1).

There is an Android game made in Flash that was packaged using Adobe AIR, but it no longer works for Android versions above 7. I was wondering if it is possible to repackage this game using HARMAN's Adobe AIR?

I have downloaded HARMAN's Adobe AIR and attempted to repackage the application using the ADT package command. I used the application.xml file that was present in the APK's assets/META-INF/AIR/ folder. However, this application uses extensions, and it appears that ADT expects ANE (AIR Native Extension) files, or is there some other way?

I couldn't find the ANE files online. But some Chinese hackers were able to repackage the app, working in Android 10, and the folder assets/META-INF/AIR/extensions folder has suffered no changes in comparison with the original apk. The files in the folder lib/armeabi-v7a were updated however, and include a new one called libX86Bridge.so.

The extensions that the original app uses are:

• com.adobe.ane.social
• com.milkmangames.extensions.AndroidIAB
• com.chartboost.plugin.air
• com.milkmangames.extensions.CoreMobile
• com.jirbo.airadc.AirAdColony
• com.milkmangames.extensions.GoViral

I started to build a project, that has a map of where the uses are living and it can help them to set workouts places, pretty simple, you can see the demo right here. I used Geolocation API and Leaflet library to make it.

And some beginning days, it displayed correctly the city where im living, but a few days ago, when I open it, it gives me wrong location, wrong city, which is about 90km away from my city. And today, I got a second wrong location, which is more 300km away.

I checked on other browser and it also has the same problems. I used my phone to check the location, it appears very true, even my phone and my computer use the same Wifi.

Please help me, i know that this question asked many times on Stack Overflow, but i didn't get helped. Im not sure if im undercontrolled by hackers or not, your answers are very important to me, thank you very very much readers.

I'm using azure functions which work great for me. But my concern is: How can I avoid hackers from doing "mass api calls" in order to hack me or to raise my billing for example?

I have an express app with MongoDB. It creates a user id for each user document. This user id also get encoded in jwt, which creates an illusion for new devs that user id must not be sent to front end in plain text form.

Can someone explain how sending user id to front end can create security issues? As much as i know hackers can't create a jwt with it without my secret string. Neither my express app listens for this user id anywhere in backend. But its critical for frontend as it is being used as seller Id.

I'm working on a script with Python that will generate a joke using an API I found online. (https://sv443.net/jokeapi/v2/). However, some of the setup/question parts of the joke use JSON Data, which varies between being 'setup' and 'joke'. I'm looking to see if I can write a script that will check which one the response is pulling. I have my script here:

I have 10+ legacy VB6/VB.NET applications. They establish connections to databases (ODBC/Thick client). The connections strings are all just strings in the source, plain text. My current task is to remove all occurrences of the database's password; I'm trying to decide the best approach.

What I've gathered/decided thus far:

• Using just the app.config is not enough. The production DB password would then be in the appname.manifest.config on the user's machine.. in plain text! Unacceptable for my needs.

• Encryption/Decryption (app.config with ConfigurationManager .NET class) on the main load/close events is an option. Is it a good one? Tim Corey says don't do it.. ugh.

• I have all the DB passwords available on the IIS site that my web services use. They are stored in the connection strings (web.config) correctly. I am able to retrieve them from web services.. why shouldn't I use a web service to return the correct connection string? Because of security reasons - authorization and authentication.. is that solely it?

Use a web service call to return the database password, making sure your security is perfect?

Edit: You some real options when removing the password from your legacy database application:

• Just update your password and continue the cycle. Re-publish everything :(
• Refactor the code, and remove database operations out of the view section of your desktop code. Put it into a web-service. Do NOT write SQL within your views/forms at all costs!
• Use a web-service to return your connection string lol. Not great - works but not recommended unless you don't feel there are enough negatives with this solution. (Authen/Authorization/Hackers/its janky/etc)
• Use app.config and be OK with your password being in plain text. Optionally encrypt it. Salt + Hash would be GREAT! This is the ideal solution IMO if it wasn't such a huge task. <--

I need to create normal urls like what wordpress does. Ex: https://www.website.ext/mypage And have them load pages from the database, not just static page files. But like how wordpress and other cms's do.

I'm well aware of the use of url parameters, such as /mypage?ID=124&fname=John But those are sloppy and can also invite hackers. And I don't want that stuff in my urls if I can avoid it.

How do they have a url to a page that only exists in the database? How do you connect https://www.website.ext/mypage to something that displays in the browser without having an actual "mypage" file and still have these clean urls?

I just can't figure out how it's done. I've messed around a bit with .htaccess things, but I'm not real educated on htaccess stuff.

I suppose I should add that I am working with php7 and MySQL database.
