How to downgrade or disable Cursor auto-updates

Cursor is a great tool, but a lot of devs (me included) have experienced reliance problems with recent updates. In my case, the experience running Cursor 0.47.x is entirely different from running 0.45, and not in a good way. As additional problem, Cursor will auto-upgrade by default as soon as you launch the app, and the way to block this auto-upgrade is not clear. How to disable Cursor…

How to add music and sounds to an iOS or macOS game with AVFoundation

If you're running background music and then you trigger a sound the music will stop. Here's how to fix it and add music and sounds.

While working on adding music and sounds to my latest project I found a problem: If you’re running some background music and then you trigger a sound ( for example by picking up some item ) the music will stop, as you’re overriding the sound with the new object. In order to fix this we can use AVAudioSession in iOS: import AVFoundation let audioSession = AVAudioSession.sharedInstance() do…

Creating a game for iOS with Swift and SpriteKit

Creating a simple iOS game for iPhone with Swift and SpriteKit

After a few months learning Swift and UIKit, as well as playing with some of the iOS libraries it was finally time to get acquainted with SpriteKit, Apple’s framework for creating 2D games. I worked on an iteration of the classic Pong, as the core game loop is very basic, and wrote about it going through the different failures and blocks I faced during development. I work on this by creating…

RSI analysis in Python: Technical implementation - This Python script will pull all necessary data from a ticker and return its RSI, this way we can work directly with the data #trading #python #100daysofcode

The RSI or Relative Strength Index is one of the main momentum indicators I personally use when making decisions about an options or stock trade, not as a main indicator, but a good tool to confirm the current momentum of a stock. All tools I’ve found or used so far ( broker custom paid tools included ) gives this indicator visually, so you can check where the RSI is on a certain period or a…

Building custom trading tools with Interactive Brokers and Python (I)

When investing or trading there’s a lot of research, analysis, and work going on behind every trade. Generally this is very time consuming and prone to error, and is very easy to miss a potential trade or entry point that you prepared in advance just because we were not ready that day, or something else came up that took your attention away. Even if you have all the alerts and indicators you’d…

How to get insider trading data from the SEC database using Python

How to get insider trading data from the SEC database using Python

Company insiders are forced to report their buy/sell operations to the SEC through form-4, and this can give us clues about the business direction. While insider selling is not always a bad sign, insider buying generally is good as shows insider confidence in the company’s future. That said, is a waste of time to have to check the SEC website and the EDGAR database constantly (and manually) in…

Java Roguelike notes (4/13): How to add game collisions #roguelike #java #indiedev

I’m modifying the original move() method to add a collision check each time the player presses a button, this is reduced to: 1) Check collisions via .intersects() , as our custom class Tiles extends the Java Rectangle class, we can use this built-in method.2) If collisions return true, call backToPreviousPosition(direction)3) If backToPreviousPosition(direction) is called, return the player to…

Java Roguelike notes (3/13): How to place random items and enemies in our dungeon #roguelike #java #indiedev

The code for both methods (place items and place enemies) is very similar, but contains some differences: We create a reduced sublist from listOfFloorTilePositions , this is our list with all Floor Positions in our map, also works as our list of available positions to spawn something on top.Shuffle and randomize the sublist, then instantiate a new Tile at that positions, and modify each list…

Java Roguelike notes (2/13): Creating a procedurally generated dungeon in Java in order to get a random level in each run.

The algorithm that creates a procedural map is based on my previous post and algorithm in C# , most of work was trying to adapt it to Java and had to take different approaches until I could finally translate it. The process goes as follows: We generate a basic Tile Board, where each point is a coordinate. Here comes the first difference, while in C# I was using Vector2, in Java I used…

Getting out of the comfort zone: Starting with Java #0: Hello Rogue

So I decided to give Java a go. Why? No real reason, it was the first language I tried many years ago and the first time I abandoned coding 😀 . Several reasons come to mind: This “coding thing” was just too abstract, at the moment my English was zero, and there was not as many resources as you can find today, it was just frustrating. Now, after many years of tinkering in other languages and…

How to create a slow motion effect in Unity and C#

How to create a slow motion effect in Unity and C#

I was following a Brackeys tutorial (credit where is due) in order to get back to speed with Unity after a long hiatus and he showed a kind of matrix-effect on game over that can be applied to multiple situations, so I decided to play with it and use it in my future (if any) games. This is how it looks like after a quick prototype re-using Longanizers concept art:
