kandi X-RAY | ladder Summary
Ladder started life as a very simple database migration system. It's grown over time to the beast you see before you. It's written in PHP 5, and supports the popular MySQL database server.

QUESTION
I have a KinematicBody2D (player) and an Area2D (ladder). With the following code I get clean enter and exit events that happen as the player touches and leaves the Area2D object e.g. touch Area2D and a single "enter" prints. Move back and a single "exit" prints.
...ANSWER
Answered 2022-Feb-28 at 17:57Godot is doing what you are telling it to do.
The call set_collision_layer_bit(0, false) would be disabling the collision between the KinematicBody2D and the Area2D which means they would no longer be colliding. And since they stop colliding, you get a "body_exited" signal.
I want to turn off collisions so the player can pass the object and re-enable them when he passes and leaves the Area2D object
The Area2D do not stop physics bodies (StaticBody2D, KinematicBody2D, RigidBody). There must be something else doing that. For example, if you added a StaticBody2D to the ladder, or made it with a TileMap where the tiles have collision, those could stop your KinematicBody2D.
I think the simplest approach would be to put the Area2D in a different collision layer, so you can disable the collision that stops the KinematicBody2D without disabling the Area2D.
Other options to disable collisions include:
- Disabling a
CollisionPolygon2DorCollisionShape2Dby settingdisabledtotrue. Note: you cannot to do this while Godot is resolving collision response. To avoid that, useset_deferredto change the value ofdisabled. - Adding a collision exception by calling
add_collision_exception_with. Useremove_collision_exception_withto remove the exception. This is a more fine grained tool that should be used sparingly (if you are adding lots of exception, prefer using collision layers and masks).
Addendum: An option for the TileMap is to have two version of the tile, one with the collision and one without it. And the swap them in runtime with set_cell. However, consider using a scene instead. In fact, you might want to set the cells in the designer and replace them with actual scenes in runtime. See How to use SCENES in a TILEMAP(And 9 MORE TRICKS) | Godot Engine. You may even do it only when the player gets nearby, see How to create large Sidescrolling Map in Godot?.

QUESTION
I've got data with time (seconds) on the x axis and intensity (in relative fluorescent units, or rfu) on the y-axis. It's generated by watching fragments of DNA pass a camera - the bigger the DNA fragment the bigger the time. There are 23 fragments of known size (in DNA base pair units, bp), and therefore there should be 23 peaks. As I know the size of the DNA fragments in bp, I want to recalibrate the x-axis from time (seconds) to base pairs (bp) using a linear model.
Unfortunately there is quite a lot of noise in the data that produces spurious peaks. The only way to confidently tell the true ones from the false ones is that the false ones don't fit the expected pattern in DNA base pairs.
I've provided data from one sample at this link in a data frame called demo. Unfortunately it's too large to paste below.

I can pick out all the peaks as follows.
...ANSWER
Answered 2022-Jan-04 at 18:39Before plotting, doing some data manipulation to pull out the maximum value for each of the 23 DNA fragment groups with base R max function, and adding the max plot with additional geom_ layer for the max values.
Here is small reprex example that plots the max value for each group with "red".

QUESTION
Good morning.
I am developing a Web API using Net 6.
The preliminary structure of the API is shown in the figure.
ContractGpdApi - this is the direct assembly of the API. It has a reference to the ContractGpdApi.ServiceInterfaces assembly. ContractGpdApi.ServiceInterfaces - this assembly containing the DTO classes (business models) and service interfaces. ContractGpdApi.ServiceImplementations - this assembly contains classes that implement the ContractGpdApi.ServiceInterfaces assembly interfaces. The assembly adapts the methods and classes of the ContractGpdApi.DbServiceInterfaces assembly into the methods and classes of the ContractGpdApi.ServiceInterfaces assembly. ContractGpdApi.DbServiceInterfaces - this assembly contains classes and database access layer interfaces. ContractGpdApi.DbServiceImplementations - this assembly contains classes that implement the ContractGpdApi.DbServiceInterfaces assembly interfaces. The assembly contains a reference to the ContractGpdApi.DbServiceInterfaces assembly, as well as references to the microsoft.entityframeworkcore, microsoft.entityframeworkcore.sqlserver assemblies
I ended up implementing the Ladder pattern and dividing the CUI into loosely coupled layers.
The DB layer is represented by two assemblies: ContractGpdApi.DbServiceImplementations and ContractGpdApi.DbServiceInterfaces.
The business work layer is represented by two assemblies: ContractGpdApi.ServiceImplementations and ContractGpdApi.ServiceInterfaces.
Accordingly, assembly ContractGpdApi will be a kind of root where you load and embed dependencies, loosely linked assemblies.
The following errors occur when loading assemblies:
- Could not load file or assembly 'ContractGpdApi.DbServiceInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The specified file cannot be found.
- Could not load file or assembly 'Microsoft.EntityFrameworkCore, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The specified file cannot be found.
All other assemblies are loaded normally. Contents of the ContractGpdApi.csproj file:

I finished up my first GUI project that allows the user to open any PDF file by wither typing a product key, or manually find it using a tree view. I have all the files in the same folder as the application, the problem is that when I used pyinstaller to make it an .exe it wont pull up. and anytime I move it nothing pulls up because the code is linked to that specific location. my question is how do you write it to where the filepath is linked to a specific folder, and even if said folder moves, it still accesses those files?

Word Ladder with mandatory points in the middle
...ANSWER
Answered 2021-Oct-14 at 05:02This can be done in exactly the same time complexity as Dijkstra's algorithm using a small augmentation. We replace every vertex v in the original graph with two vertices (v, 0) and (v, 1), denoting whether we've visited a detour yet or not. We're now searching for the shortest path from (start, x) to (end, 1), where x is 1 or 0 if start is or is not a detour, respectively.
The priority queue Q is initialized with only (start, x) at a priority/distance of 0. The main loop over neighbors in Dijkstra's algorithm transforms into this (pseudocode):

Install ladder
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
