This is intended to answer a question Casey Muratori had on twitter about why would anyone choose Unity over Unreal. The short answer is, I have no clue. Well, I kinda do know why you WOULDN'T choose it, so maybe I'll tackle it that way, pros/cons. Read on.

There's a few pros I could think for Unity:

• Their text-based asset serialization which makes collobration work and resolving conflicts much easier. Unreal's assets are all binary and it's really built well for Perforce, if you're more than a handful of people working together not using Perforce (e.g. git) you'll have a less of an idea time.

• Their undo/redo system I found is a lot more graceful/lightweight than Unreal's. Undoing in Unreal sometimes doesn't work reliably or go back a dozen entries in history, and just reverts back your selection state and is a bit intrusive (not sure if that was imporved in UE5)

• Their animation editor (for me as a non-animator) I found was friendlier and easier to work with

• The profiler is nice and very easy to us

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

Introduction

The serial port protocol is one of the most long lived protocols currently in use. According to wikipedia, it has been standadized in 1969. First, a note: here we're talking about the RS232 serial protocol. This note is necessary because there are many other serial protocols, like SPI, I2C, CAN, and even USB and SATA.

Some time ago, when the Internet connections were done using a 56k modem, the serial port was the most common way of connecting a modem to a computer. Now that we have ADSL modems, the serial ports have disappeared from newer computers, but the protocol is still widely used.

In fact, most microcontrollers, even the newer ones have one or more peripherals capable of communicating using this protocol, and from the PC side, all operating system

Quick Tips for Fast Code on the JVM

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.

This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea
