There are no easy decisions in software architecture. Instead, there are many hard parts--difficult problems or issues with no best practices--that force you to choose among various compromises. With this book, you'll learn how to think critically about the trade-offs involved with distributed architectures.

Architecture veterans and practicing consultants Neal Ford, Mark Richards, Pramod Sadalage, and Zhamak Dehghani discuss strategies for choosing an appropriate architecture. By interweaving a story about a fictional group of technology professionals--the Sysops Squad--they examine everything from how to determine service granularity, manage workflows and orchestration, manage and decouple contracts, and manage distributed transactions to how to optimize operational characteristics, such as scalability, elasticity, and performance.

By focusing on commonly asked questions, this book provides techniques to help you discover and weigh the trade-offs as you confront the issues you face as an architect.

Analyze trade-offs and effectively document your decisions
Make better decisions regarding service granularity
Understand the complexities of breaking apart monolithic applications
Manage and decouple contracts between services
Handle data in a highly distributed architecture
Learn patterns to manage workflow and transactions when breaking apart applications

آقا یه نکته فنی از

python3 -m http.server

برای ارسال یه فایل حجیم روی بستر ریورس یا اینترنت استفاده نکنید، این روش ارور هندلینگ مناسبی نداره وسط راه دست و پا تون رو تو پوست گردو می‌ذاره.
روش های بهتر و با ضمانت‌تری مثل rsync استفاده کنید بهتره.
واسه مولتی تی‌سی‌پی استریم bbcp هم خوبه.

توضیحات:

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks.

The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does.

This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics:

Memory management, including file buffering, process swapping, and Direct memory Access (DMA)
The Virtual Filesystem layer and the Second and Third Extended Filesystems
Process creation and scheduling
Signals, interrupts, and the essential interfaces to device drivers
Timing
Synchronization within the kernel
Interprocess Communication (IPC)
Program execution

Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.

#امنیت

باگ امنیتی شبکه‌ی 2G

این نسل کلا احراز هویت شبکه نداره، با IMSI catchers میشه موبایل‌هارو فریب داد که بهش وصل بشن (چون گوشی فکر میکنه این دکل مخابراتی واقعی هست). کارهای زیادی مثل پیدا کردن موقعیت، شنود تماس، پیامک و ... میشه انجام داد.

حتی وقتی شما دارید از 4G استفاده میکنید میشه اتصال شما رو دستکاری کرد که به 2G سوییچ کنه. توی دنیا دولت‌ها و مجرم‌ها ازش استفاده میکنن. با این حال دولت‌ها خیلی هم بهش نیازی ندارن چون اونا قابلیت‌های شنود قانونی (lawful interception - LI) در شبکه‌های تلفن همراه رو دارن.

مجرم‌ها میتونن با تجهیزاتی در حدود ۵۰ دلار این کار رو انجام بدن. با این حال باگ‌های امنیتی 2G کم نیستن، تا جایی که از اندروید 12 یه گزینه اضافه کردن که میتونی 2G رو کلا غیر فعال کنی.

یه اصل هست «چیزی که تو بتونی شنود کنی بقیه هم میتونن» به خاطر همین دولت‌ها (۶۱ کشور) برنامه‌ریزی کردن 2G رو کلا خاموش کنن، یه جاهایی مثل ژاپن و استرالیا دیگه 2G نداره و بقیه هم تو فرایند پایان دادن به این تکنولوژی هستن.
