playful | A Ruby implementation of UPnP that works with Ruby

I am trying to write my first neural network to play the game connect four. Im using Java and deeplearning4j. I tried to implement a genetic algorithm, but when i train the network for a while, the outputs of the network jump to NaN and I am unable to tell where I messed up so badly for this to happen.. I will post all 3 classes below, where Game is the game logic and rules, VGFrame the UI and Main all the nn stuff.

I have a pool of 35 neural networks and each iteration i let the best 5 live and breed and randomize the newly created ones a little. To evaluate the networks I let them battle each other and give points to the winner and points for loosing later. Since I penalize putting a stone into a column thats already full I expected the neural networks at least to be able to play the game by the rules after a while but they cant do this. I googled the NaN problem and it seems to be an expoding gradient problem, but from my understanding this shouldn't occur in a genetic algorithm? Any ideas where I could look for the error or whats generally wrong with my implementation?

Main

I'm working on my little portfolio page and wanted to put some background/fun stuff on my About page. Right now, it displays the information on ALL 4 article-columns at once, instead of just the one I'm hovering on.

Here's the code and logic I have.

I am using dotnet-sdk 3.1, entity framework, and sqlite on a mac.
I can't seem to get my Db to accept the SearchMetadata object or any of the classes that are linked to it with a foreign key. Whenever I try to run _db.SaveChanges() I get this error

My relevant ApplicationDbContext.cs code looks like this:

Im currently building a filter that gets executed upon click on react.

The initial value of the filter in the state is as follow:

I'm trying to generate a state property dynamically for an array of filters. These filters contain different checkboxes "names" and "isChecked" for each. See below example:

I have a problem with a puzzle named "A child's play" of Codingame. I code in typescript !

The statement is :

For several years now, in elementary schools, we have seen the emergence of a new educational model, playful programming. The students must program a small robot using assembly blocks. This allows them to get familiar with programming from an early age while exercising their logic and perception of space.

You are a student at one such school. The purpose of the exercise is simple: your teacher has crafted a circuit for your robot, told you how many moves n the robot may make, and you must find out the final position of the robot at end of execution.

To do this you need to know some principles of robot operation.
– When the robot encounters an obstacle (represented by #) it turns right (on same operation) until there's no obstacle ahead anymore. Otherwise on an empty area (represented by .) it moves straight ahead.
– The robot initially moves upwards.
– The robot stops after n moves.
– The top left corner represents the coordinates (0,0)
– The robot's environment is represented as follows, where O is the robot's initial position:

...#........
...........#
............
............
..#O........
..........#.

I'm block at the test 4, because my solution is not optimized.

It gives me in the console: The process timed out. This may mean that your solution is not optimized enough to handle some cases.

I tried to change the loop for a "while" loop and change and change the "switch" condition, for an "if-else" condition.

Can you help me to find a better solution or a other way to do the tests?

So before I go deeper into the problem I want to point out simple requirements of how I want this to be accomplished, if possible.

a) Because I'm modifying the Woocommerce template which uses Bootstrap 3 I can't just simply switch to Bootstrap 4 even though the newest version would really help me a lot.

b) I can use any technique or custom code as long as it works fine even if it's out of the Bootstrap 3 framework scope.

So here's the fiddle: https://jsfiddle.net/wL1kjc0y/

I also want to make this product list more playful so for instance, for odd items I want to make the product name, text, button to be floated to the right side, so that the product image would appear to the left, and pretty much the same for even items - image floated to the right and text contents floated to the left.

I created for text contents div.col-lg-6 element and col-lg-6 for the image. The problem is that .pull-right class does not work if I apply it on div.col-lg-6 element which wraps Product contents. And also because Bootstrap 3 doesn't use flexbox I added this code:

I am trying to make a script that automates download of SpigotMC BuildTools , detect input version ( sh build.sh ) , and set a variable wich is used if the version is greater or equal with 1.14 (since this release, SpigotMC discontinued the automation of auto-compilation of craftbukkit by default. Now it compiles only the spigot jar and I need both of them compiled for my personal purposes.)

Here is what i have tried (I'm a linux newbie, so this might be messed up) :

I am trying to get the data inside these script tags, but I cant seem to be able to convert into json so i can parse it after I read it. The data im interest in is name,image,sku, and price.
