Алгоритмы Google, тряска выдачи, и как обезопасить свой бизнес
Не позициями едиными, или как привести трафик на ваш сайт?
Многоканальный интернет-маркетинг: как начать?
Презентація виконана в програмі Power Point і призначена переважно для початкової школи. Презентація допоможе учням у формі гри запам'ятати лексику по темі " Частини тіла ".Презентація може бути використана на будь якому уроці, де є дана тема.
Многоканальное продвижение сайтов в ИнтернетеStudio oneTOUCH
Мы профессионально занимается продвижением сайтов уже 8-й год. Количество успешных проектов около 100. У нас собственное видение процесса продвижения сайта, оно во многом отличается от большинства представителей на рынке оказания SEO-услуг. Самое главное отличие – мы развиваем сайт как изнутри (контент), так и снаружи (внешние ссылки). Продвижение - это сложный процесс, а не простая покупка ссылок на сайт.
Продвижение интернет-магазина – это не выведение интернет-магазина по профильным запросам на первые строчки поисковых систем и привлечение оттуда посетителей. Продвижение – создание потока продаж и прибыли интернет-магазина. И совершенно не важно, какие способы будут задействованы. В продвижение интернет-магазинов мы ориентируемся только на продажи и целевые действия (звонки) посетителей сайта и на их постоянное увеличение.

The document discusses the debate around whether or not to write tests for iOS apps. It presents arguments on both sides of the debate, including that tests are not needed, take too much time, and are often broken by new OS releases. It also notes that testing is hard, particularly for UI, but provides tips for better testing practices like writing isolated, fast, and self-verifying tests. The document concludes by offering suggestions for developers who are not writing tests, such as layering code and following principles like YAGNI (You Aren't Gonna Need It).
This document discusses software development best practices including:
- Extreme programming principles like unit testing, pair programming, continuous integration and iterative design.
- Failing small and often through testing to catch issues early.
- Using React and Redux for component-based architectures with isolated components.
- Incremental development through the smallest possible changes and refactoring rather than large rewrites.
This document introduces Roman Sevastyanov and provides information about load and stress testing. It defines load testing and stress testing, outlines their goals, and discusses different testing types and tools. Load testing aims to determine a system's user capacity and find bottlenecks, while stress testing tries to overwhelm resources. Popular open-source tools mentioned include JMeter for web, services, and databases, and Siege for simple command line testing. Other tools and cloud services are also listed, along with example test environments and additional resources.
The document discusses React features including fragments for flattening component hierarchy, component return types allowing arrays or strings, simplified component lifecycle with error handling, context for passing data to children without props, portals for rendering outside the root node, and improved refs with forwarding and createRef.
QA Evening Максим Колотилкин - Test State PatternArtjoker
Wix has 20 software engineers across 4 cities testing 3 different projects. They developed infrastructure for writing, executing, analyzing and managing Selenium-based tests. To address unstable tests, they implemented a test-state pattern where each test begins in a "Beta" state, is run multiple times, and potentially transitions to "Stable", "Flaky", or "Failed" states based on pass/fail criteria over time. This provides a way to continuously monitor test stability without separate annotation groups.
Performance: How to build an app instead of slideshowArtjoker
This document discusses performance best practices for building Android apps. It provides 7 rules: 1) Avoid sluggishness by maintaining high FPS and avoiding skipped frames; 2) Use appropriate colors like gray instead of alpha layers; 3) Limit view hierarchy complexity to 3 levels using ConstraintLayout; 4) Avoid expensive calls like onLayout() and onMeasure() except for specific cases; 5) Perform IO in background threads and use object pools to reduce garbage collection; 6) Debug performance issues using tools like gfxinfo before optimizing code; 7) Treat performance regressions seriously with tests and monitor using Developer Console. The document emphasizes optimizing for smoothness over features to provide good user experience.
The document provides tips for increasing productivity when using Android Studio by describing keyboard shortcuts and tools for common tasks like hiding/showing windows, navigating files, running and debugging apps, and exploring app resources and code. It recommends extensions for navigating Android SDKs and APIs from within the Chrome browser.
