Measuring your program speed correctly

Measuring program speed accurately involves considering nanosecond precision, especially with CPUs operating at GHz frequencies.
The time command in POSIX systems provides real, user, and system times for processes, giving insights into program performance.
Using gettimeofday and getrusage syscalls in C/C++ allows for measuring CPU and system resource usage with microsecond precision.
Clock_t provides a more granular measurement based on hardware clock ticks, offering microsecond precision for timing computations.
To achieve nanosecond precision, C++'s chrono library with high_resolution_clock can be utilized for accurate time measurements.
The Time Stamp Counter (TSC) on x86 processors offers cycle-level precision using the rdtsc assembly instruction.
By leveraging TSC, one can achieve nanosecond level precision for program execution time, surpassing other timing methods.
Comparing different timing methods showcases the trade-offs between precision and overhead in measuring program performance.
Optimizing code and utilizing lower-level hardware-specific instructions like rdtsc can significantly enhance timing precision and accuracy.
Achieving precise timing measurements is crucial for understanding and optimizing program performance, from milliseconds to nanoseconds.
Overall, the journey from millisecond to nanosecond precision highlights the importance of choosing the right timing method for accurate performance assessment.

From Pixels to Plans: Cracking 2048 with Reinforcement Learning and Beam Search

The 2048 AI project's modular design includes separate directories for environment logic, agent policies, utility functions, and entry-point scripts, ensuring clear responsibilities separation.
The Game2048Env class is crucial, providing a simulation environment based on 2048 game rules, managing tile movements, scoring, and reward assignment.
Proximal Policy Optimization (PPO) is used, optimizing policies directly while preventing large updates to maintain training stability.
PPO agent's training involves collecting experience tuples and updating policies periodically with clipped objectives to prevent large policy shifts.
The PPO agent reached a maximum tile of 512 after 1000 episodes of training but struggled to consistently reach the 2048 tile due to sparse rewards and high outcome variance.
Beam Search, a planning-based agent, simulates possible futures with a heuristic evaluation function, avoiding the need for extensive training and generalizing effectively.
Beam Search scored significantly better than PPO in reaching higher tiles in 2048 due to its efficient search and utilization of local information.
The PPOBeamHybridAgent combines PPO and Beam Search, using PPO in early stages and transitioning to Beam Search in complex board states, showing promise in tactical scenarios.
While PPO offers flexibility and generalization, Beam Search excels in exploiting local information efficiently, making it valuable for games like 2048.
Future work could explore the effective blending of planning and learning in AI for enhanced decision-making.

How to Scrape TikTok to Obtain Video Information?

TikTok is a valuable platform for data gathering, and this article explains how to scrape TikTok for video information through hidden API or embedded datasets.
Scraping TikTok allows for trend analysis, lead generation, and sentiment analysis by extracting user profiles, demographics, videos, hashtags, comments, engagement metrics, and trends.
The process involves extracting data like view counts, video descriptions, music names, release dates, tags, likes, comments, shares, and bookmarks through HTML structure analysis.
To build a TikTok scraper, you need to understand the structure of TikTok videos and locate key data elements like view count, video description, tags, music title, upload date, like count, comment count, share count, and bookmark count.
The scraping code provided in the article enables the extraction of video information, handling of CAPTCHA, and downloading videos.
While manual scraping can be tedious, using a third-party scraping API can enhance efficiency, accuracy, and applicability across various business scenarios for collecting TikTok data.
The API retrieves Walmart product details efficiently and accurately for price monitoring, inventory tracking, review analysis, and market research.
Scrapeless offers a powerful unofficial TikTok API for gathering large-scale TikTok data, including popular videos, user profiles, individual video posts, and video/music-related data.
To scrape TikTok data using the API, you create an API token, enter TikTok API details, configure request parameters, and start scraping for video search results or user profile information.
With the scraping API, you can easily extract TikTok data without complex coding, enabling trend analysis, research, and data exploration with simplified parameter configuration.
