any and some

Swift introduces the any and some keywords to handle protocol types with clarity and intent. These keywords serve complementary purposes and are used to distinguish between existential and opaque types.

Safety doesn’t happen by accident

An authentication system is a critical component of any application or system that requires secure user interaction. It ensures that only authorized individuals or entities can access specific resources, data, or functionalities.

Draw this, draw that

Recently I was faced with the task of drawing 3D objects for my 3D printer. As a result, I searched a bit for a suitable tool. One of the very interesting solutions was OpenSCAD.

any and Any

Swift is a powerful, expressive programming language developed by Apple for building software across its ecosystem. One of the most important features of Swift is its strong type system, which helps developers write robust, predictable, and easy-to-maintain code.

RSA Encryption

Recently, I encountered RSA encryption while working on a project and realized its critical role in securing data. RSA (Rivest-Shamir-Adleman) encryption is a public-key cryptographic system widely used for secure data transmission. Let’s explore its purpose, history, and functionality.

.xcframework

As developers increasingly target multiple Apple platforms—iOS, macOS, iPadOS, watchOS, and tvOS—there’s a growing need to share code across these environments. Sharing code not only improves development efficiency but also ensures consistency across apps, reduces maintenance efforts, and speeds up updates.

Understanding @preconcurrency in Swift

Swift’s @preconcurrency attribute is a powerful tool introduced to help developers integrate legacy APIs into Swift’s modern concurrency model. It ensures compatibility and suppresses compiler warnings when working with older APIs that are not explicitly marked as concurrency-safe.

Train the mind to solve

Often, during development and in real life we face various problems that are hard or even impossible (at first look) to solve. As a result, some of us look for alternatives or even give up by accepting simpler or different ways, and another part continues to gnaw the problem until … read more »

Battery indicator in flutter

Some time ago I started to play with flutter and dart. As for me - it looks very good: language available functionality within, platforms and support for various features - looks very promising.

Another language, same approach

Exchange and process data - is an essential part of any modern application. U can’t achieve results without data. Sometimes data can be produced or obtained from remote sources.

Probe of software design with Alloy

Sometimes we have an idea and we want to check that this idea has a realistic chance for life. In other words, we want to check the design of the idea. If we are talking about software - often we want to check the design of some approach.

Automate everything

Automation of each small amount of work that is repeatedly needed in your daily work can significantly speed up everything.

BeagleBone® Blue - duplicate & distribute

One more post related to Beaglebone® Blue. At this time I just want to put here small notes about making a bootable self-flashing SD card with a pre-configured board config, so distribution becomes more painless.

BeagleBone® Blue - debug as root

Depending on the app’s functionality and our needs, u may faced with a situation, when u need root permission to do certain things on the PC - open some port for network connection or use memory binding or some other stuff.

SSH vs Eclipse - not a friend anymore?

Often during development, we need to have access to the filesystem. Password-based access is not always a way u want to use, ssh is here for rescue.

BeagleBone® Blue - remote debug

In the last few articles, I covered the intro theme related to Beaglebone® Blue. So for now, we already have configured connection to the board and Eclipse installed and configured for cross-compile process. But what we want - is an option to debug in real-time, reviewing and examining variables … read more »
