#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.

The bible of all fundamental algorithms and the work that taught many of today’s software developers most of what they know about computer programming.

Volume 1 – Fundamental algorithms
        Chapter 1 – Basic concepts
        Chapter 2 – Information structures

Volume 2 – Seminumerical algorithms
        Chapter 3 – Random numbers
        Chapter 4 – Arithmetic

Volume 3 – Sorting and searching

Volume 4B – Combinatorial algorithms
        Chapter 7 – Combinatorial searching (part 2)

Countless readers have spoken about the profound personal influence of Knuth's work. Scientists have marveled at the beauty and elegance of his analysis, while ordinary programmers have successfully applied his "cookbook" solutions to their day-to-day problems. All have admired Knuth for the breadth, clarity, accuracy, and good humor found in his books.

Primarily written as a reference, some people have nevertheless found it possible and interesting to read each volume from beginning to end. A programmer in China even compared the experience to reading a poem. Whatever your background, if you need to do any serious computer programming, you will find your own good reason to make each volume in this series a readily accessible part of your scholarly or professional library.

Learn the Root Causes of Software Vulnerabilities and How to Avoid Them

Commonly exploited software vulnerabilities are usually caused by avoidable software defects. Having analyzed tens of thousands of vulnerability reports since 1988, CERT has determined that a relatively small number of root causes account for most of the vulnerabilities.

Secure Coding in C and C++, Second Edition, identifies and explains these root causes and shows the steps that can be taken to prevent exploitation. Moreover, this book encourages programmers to adopt security best practices and to develop a security mindset that can help protect software from tomorrow’s attacks, not just today’s. Drawing on the CERT’s reports and conclusions, Robert C. Seacord systematically identifies the program errors most likely to lead to security breaches, shows how they can be exploited, reviews the potential consequences, and presents secure alternatives.

Coverage includes technical detail on how to

    Improve the overall security of any C or C++ application
    Thwart buffer overflows, stack-smashing, and return-oriented programming attacks that exploit insecure string manipulation logic
    Avoid vulnerabilities and security flaws resulting from the incorrect use of dynamic memory management functions
    Eliminate integer-related problems resulting from signed integer overflows, unsigned integer wrapping, and truncation errors
    Perform secure I/O, avoiding file system vulnerabilities
    Correctly use formatted output functions without introducing format-string vulnerabilities
    Avoid race conditions and other exploitable vulnerabilities while developing concurrent code

The second edition features

    Updates for C11 and C++11
    Significant revisions to chapters on strings, dynamic memory management, and integer security
    A new chapter on concurrency
    Access to the online secure coding course offered through Carnegie Mellon’s Open Learning Initiative (OLI)

Secure Coding in C and C++, Second Edition, presents hundreds of examples of secure code, insecure code, and exploits, implemented for Windows and Linux. If you’re responsible for creating secure C or C++ software–or for keeping it safe–no other book offers you this much detailed, expert assistance.
