Upsetting Opinions about Static Analyzers

Static analysis tools have advanced far over the time they've been around. They no longer resemble the "linters" that were in active use 20 years ago. But some programmers still view them as extremely primitive tools. And that's very sad. It hurts to see the static analysis methodology in general and our PVS-Studio analyzer in particular treated that way.Read more → Read more

[Translation] Database using ScriptableObjects with save/load system

IntroductionEach game has data that game-designers work with. In RPG there is a database of items, in match-3 — the cost in the crystals of tools from the store, in action — hit points, for which medical kit heals. There are many ways to store such data — someone stores it in tables, in XML or JSON files that edit with their own tools. Unity provides its own way —... Read more

Compensation for Error Caused by Limited Gain-Bandwidth of Operational Amplifiers in Low-pass Filters

An operational amplifier has the internal compensation circuit for stability which limits its working bandwidth. Frequency response of the compensated Op Amp has slope of −6 dB/octave or −20 dB/decade. Unity gain frequency defines the bandwidth where the Op Amp is able to amplify a signal. If we multiply the gain and frequency at any point, the result is the same, allowing us to use this parameter to select the... Read more

Using Flex (Fast Lexical Analyzer Generator)

Lexical analysis is the first stage of a compilation process. It's used for getting a token sequence from source code. It gets an input character sequence and finds out what the token is in the start position, whether it's a language keyword, an identifier, a constant (also called a literal), or, maybe, some error. A lexical analyzer (also known as tokenizer) sends a stream of tokens further, into a parser,... Read more

Aspect-Oriented Programming (AOP) by source-level weaving

Aspect-oriented programming is a very appealing concept for simplifying your codebase, creating clean code, and minimizing copy-paste errors. Today, in most cases, aspects are implemented at the bytecode level, i.e. after compilation, a certain tool «weave» an additional byte code with the support of the required logic. Our approach (as well as the approach of some other tools) is modifying the source code to implement aspect logic. With introduction of... Read more
