ممکنه اگه Hyprland دارین و با nwg-look برای cursor تم ست کردین وقتی نشانگر رو روی تصویر دسکتاپ میبرین تم ریست بشه به Adwaita که برای حل این مشکل با hyprctl تنظیمات cursor رو اعمال کنین:
$ hyprctl setcursor THEME SIZE
که بجای THEME اسم تم مورد نظر و بجای SIZE اندازه نشانگر رو قرار بدین. مثلا:
$ hyprctl setcursor Dracula-cursors 24

Understand the concept of Domain-driven design and build two DDD systems from scratch that can be showcased as part of your portfolio

Key Features

    Explore Domain-driven design as a timeless concept and learn how to apply it with Go
    Build a domain-driven monolithic application and a microservice from scratch
    Leverage patterns to make systems scalable, resilient, and maintainable

Book Denoscription

Domain-driven design (DDD) is one of the most sought-after skills in the industry. This book provides you with step-by-step explanations of essential concepts and practical examples that will see you introducing DDD in your Go projects in no time. Domain-Driven Design with Golang starts by helping you gain a basic understanding of DDD, and then covers all the important patterns, such as bounded context, ubiquitous language, and aggregates. The latter half of the book deals with the real-world implementation of DDD patterns and teaches you how to build two systems while applying DDD principles, which will be a valuable addition to your portfolio. Finally, you'll find out how to build a microservice, along with learning how DDD-based microservices can be part of a greater distributed system. Although the focus of this book is Golang, by the end of this book you'll be able to confidently use DDD patterns outside of Go and apply them to other languages and even distributed systems.

What you will learn

    Get to grips with domains and the evolution of Domain-driven design
    Work with stakeholders to manage complex business needs
    Gain a clear understanding of bounded context, services, and value objects
    Get up and running with aggregates, factories, repositories, and services
    Find out how to apply DDD to monolithic applications and microservices
    Discover how to implement DDD patterns on distributed systems
    Understand how Test-driven development and Behavior-driven development can work with DDD

Who this book is for

This book is for intermediate-level Go developers who are looking to ensure that they not only write maintainable code, but also deliver great business value. If you have a basic understanding of Go and are interested in learning about Domain-driven design, or you've explored Domain-driven design before but never in the context of Go, then this book will be helpful.

Table of Contents

    A brief history of Domain Driven Design
    Understanding Domains, Ubiquitous Language, and Bounded Contexts
    Aggregates, Entities & Value Objects
    Factories, Repositories & Services
    Applying Domain Driven Design to a monolithic application
    Building a microservice using domain driven design
    Domain Driven Design for distributed systems
    TDD, BDD and DDD

چرا vscode یه هیستوری مجزا واسه شل ترمینالش نداره؟

الان بازش کردم و طبق عادت up arrow رو زدم و بعدش enter زدم.

چی شد؟ سیستم ریبوت شد. 🚶‍♂

#نکته_لینوکس

خب برای اینکه برای vscode یه هیستوری مجزا داشته باشم مقادیر

"terminal.integrated.defaultProfile.linux": "vscfish",
"terminal.integrated.profiles.linux": {
        "vscfish": {
            "path": "fish",
            "args": [
                "-C",
                "set -x fish_history vscode"
            ]
        }
    }

رو به فایل
~/.config/Code/User/settings.json
اضافه کردم.

که توی بخش اول تنظیم میکنه ترمینال vscode از پروفایلی به اسم vscfish استفاده کنه.

بعدش vscfish رو به این صورت تعریف کردم که کامند fish رو با دو تا آرگومان اجرا کنه.
آرگومان اول که
-C
هست و معادل
--init-command
یه دستور مشخص رو بعد اینکه شل اجرا شد اجرا میکنه.
آرگومان دوم هم اون دستوری هست که میخوام موقع اجرا شدن شل اجرا بشه.
که با
set -x
مقدار متغیر fish_history رو به "vscode" تغییر دادم و یه session name جدید برای ذخیره‌ی history ایجاد کردم تا از history اصلی جدا بشه.

و از این به بعد هیستوری ترمینال vscode توی
~/.local/share/fish/history_vscode
ذخیره میشه.

مطالعه‌ی بیشتر:
VSCode Terminal Profiles
Fish shell fish_history
Fish shell --init-command

پی نوشت: من از شل fish استفاده میکنم؛ بعدا برای bash یه پست جداگانه مینویسم.

#نکته_لینوکس

اگه از bash استفاده میکنین و میخواین هیستوری vscode مجزا باشه تقریبا مثل همون روال قبلی برای fish محتویات پایین رو به فایل settings.json اضافه کنین:

"terminal.integrated.defaultProfile.linux": "vscbash",
"terminal.integrated.profiles.linux": {
    "vscbash": {
        "path": "bash",
        "args": [
            "--init-file",
            "~/.vscbash.sh"
        ]
    }
}

حالا فایل
~/.vscbash.sh
رو به این صورت بنویسین:

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi

export HISTFILE=~/.vscbash_history
export PROMPT_COMMAND="history -a; $PROMPT_COMMAND"

که اول میاد bashrc رو اجرا میکنه و بعدش HISTFILE رو به فایل موردنظرمون تغییر میده.
خط آخر هم برای اینه که در لحظه هر کامندی که اجرا شد توی فایل هیستوری نوشته بشه تا اگه چندتا ترمینال باز داشتین کامندایی که تو یه ترمینال زدین همون لحظه تو ترمینال دیگه قابل دسترسی باشه. [میتونین این خط رو پاک کنین اگه بهش نیاز ندارین.]

ازین به بعد هیستوری مربوط به vscode توی فایل
~/.vscbash_history
جداگانه ذخیره میشه.

نکته۱: اگه میخواین برای هر پروژه هیستوری مجزا داشته باشین میتونین بجای اینکه یه مسیر ثابت برای vscbash_history مشخص کنین، با $(pwd) مسیر پوشه‌ای که vscode باز کرده رو بهش بدین تا فایل اونجا ایجاد بشه و هر working directory برای vscode یه هیستوری مجزا داشته باشه.

نکته۲: اگه نکته۱ رو اجرا کردین میتونین

"files.exclude": {
        ".vscbash_history": true
    }

رو به settings.json اضافه کنین تا فایل هیستوری توی File Explorer تو vscode براتون نشون داده نشه.

#نکته_لینوکس

اگه از zsh استفاده میکنین و میخواین هیستوری مجزا داشته باشین کامند:

printenv TERM_PROGRAM

رو توی ترمینال vscode بزنین و ببینین خروجیش چیه. فرض میکنیم خروجیش
vscode
باشه.
حالا توی فایل zshrc بجای
HISTFILE=~/.histfile
بنویسین:

if [[ $TERM_PROGRAM = "vscode" ]]; then
    HISTFILE=~/.vsczsh_history
else
    HISTFILE=~/.histfile
fi

و ازین به بعد هیستوری vscode توی
~/.vsczsh_history
ذخیره میشه.

پی‌نوشت: نهایتا راه های رسیدن به خدا زیاده برای bash هم میتونین روشی مثل این رو انتخاب کنین یا یه روش دیگه که توی کامنت پست قبل هست.

An ebook on design patterns and the principles behind them

Design patterns help you solve commonly-occurring problems in software design. But you can’t just find a pattern and copy it into your program, the way you can with off-the-shelf functions or libraries. A pattern is not a specific piece of code, but a general concept for solving a particular problem. They are like pre-made blueprints that you can customize to solve a recurring design problem in your code.

The book Dive Into Design Patterns illustrates 22 classic design patterns, and 8 design principles that these patterns are based on.

    Each chapter starts with a real-world software design problem, then solves it using one of the patterns.
   
    Then we dive into a detailed review of the pattern's structure and its variations, followed by a code example.
   
    Then the book shows various applications of the pattern and teaches how to implement the pattern step by step, even in an existing program.
   
    Each chapter concludes with a discussion of pros and cons of the pattern and explores its relations to, similarities with and differences from other patterns.

Why do you need to know patterns?

    Ace interviews and reviews. Questions about patterns come up at almost every programming job interview and every performance review. Get more jobs and get that raise and promotion you so richly deserve.

    Extend your programming toolkit. Patterns let you customize ready-made solutions rather than reinvent the wheel. Your code has fewer mistakes because you are using a proven, standard solution covering all hidden problems.

    Communicate better with colleagues. Just share the name of the pattern rather than wasting an hour explaining the details of your cool design and its classes to other programmers. Get the glory without the sweat.

Who is this book for?

    Pattern Beginners. If you have never studied patterns, the book explains the basic principles of object-oriented programming with real-life examples. Before diving into the patterns, we look at the design values and principles on which the patterns are built.

    Pattern Refreshers. If you studied patterns a while ago, but have forgotten things, the ebook can refresh your memory as serve as a handy reference. Quickly find sections of interest without having to read it from start to finish.

    Language Switchers. If you are switching to one of the OOP languages (C#, C++, Go, Java, PHP, Python, Ruby, Rust, Swift, or TypeScript), you will easily grasp the essence of the text thanks to the many real-world examples and analogies, supported by helpful illustrations and diagrams.

Throw out your old ideas about C and get to know a programming language that’s substantially outgrown its origins. With this revised edition of 21st Century C, you’ll discover up-to-date techniques missing from other C tutorials, whether you’re new to the language or just getting reacquainted.

C isn’t just the foundation of modern programming languages; it is a modern language, ideal for writing efficient, state-of-the-art applications. Get past idioms that made sense on mainframes and learn the tools you need to work with this evolved and aggressively simple language. No matter what programming language you currently favor, you’ll quickly see that 21st century C rocks.

    Set up a C programming environment with shell facilities, makefiles, text editors, debuggers, and memory checkers
    Use Autotools, C’s de facto cross-platform package manager
    Learn about the problematic C concepts too useful to discard
    Solve C’s string-building problems with C-standard functions
    Use modern syntactic features for functions that take structured inputs
    Build high-level, object-based libraries and programs
    Perform advanced math, talk to internet servers, and run databases with existing C libraries

This edition also includes new material on concurrent threads, virtual tables, C99 numeric types, and other features.
