How do plants get energy from the sun?
Plants use a process called photosynthesis to get energy from the sun. Through photosynthesis, plants absorb sunlight and convert it into chemical energy stored in the form of sugars and starches. This energy is used to fuel all of the plant's activities, including growth and reproduction.
How to learn coding?
1. Start with the basics.
Before you start diving into the world of coding, it's important to understand the basics concepts. You'll learn the syntax of different languages, basic data structures and control flow, and other fundamentals. You can usually find these concepts covered in a variety of coding tutorials, books, and online courses.
2. Choose a language.
Once you have a good grasp of the basics, the next step is to choose a specific language to learn. Different languages are suited for different types of tasks, so it helps to pick one that is relevant to your field. Popular web development languages include JavaScript, HTML, and Python.
3. Practice, practice, practice.
The best way to learn coding is to actually do it. Take the time to write your own code and experiment with different techniques. There are lots of websites, such as Codecademy, that allow you to test out your code and learn at your own pace.
4. Look for resources online.
The Internet is full of valuable coding resources. From online tutorials and videos to forums, blogs, and communities of coders, there are plenty of resources to get you started and help you along the way.
5. Find a mentor.
Having an experienced coder to turn to when you have questions or need help is invaluable. Although you won't find a live mentor through an online resource, you can find mentors on social media sites like Twitter and Reddit.
How to optimize database caching?
1. Use a caching system: Utilize an external caching system such as Redis, Memcache or Varnish. This will allow you to store query results and other data to speed up retrieval times.
2. Compress data: Compress relational database query results to reduce the size of the data transferred from the database to the caching layer.
3. Keep in memory: Keeping commonly used data in memory will allow for faster access and reduce database queries.
4. Enable Query Caching: This feature is available for most popular database systems and it can be used to cache frequently used queries.
5. Monitor Cache Hit Rates: Monitor the hit rate for your cache. Higher hit rates mean better caching performance.
6. Use write-through caching: Still cache write operations and propagate caches across multiple servers for better performance.
7. Tune Database Queries: Tune database queries for best performance and make sure the query is properly optimized.
8. Implement an Application Cache: Implement an application cache that can store application objects and data that is frequently accessed.
9. Minimize Contention: Utilize database connection pools to minimize contention and lock contention on database tables.
10. Scale Out Database Hosts: When necessary, add database nodes to scale out database operations and spread the load more evenly across the database hardware.
