...required. In general: - Small composable functions. - No nested code. - Avoid if statements. Branches are only ok in the simplest and unavoidable use cases. Simple clean ternaries are fine. - Along with avoiding branching, absolutely no try/catch. - Never throw. - No control loops. - No unbounded iterators. - Use maps rather than a switch or if/else. - Functions should be small, pure, and composable. - Separate configuration from code. - Use arrow function syntax. - Avoid async/await as one can accidentally block the event loop. *Testing* Fine grain testing of LangChain does not seem completely straight forward but there are current improvements to its testability and the LangSmith debugger should probably be used. Code should be decoupled so that mocks c...

I have a live Wordpress site that is being moved to a new CMS and I need to take the design and create it in Figma to pass to another team. The design is just 5 pages (homepage, blog page, single blog post, landing page and a contact page).

I can give you the live Wordpress website, or provide screenshots or whatever you need to produce the same design in Figma. You can price me per page, or for the whole project. And please let me know roughly the how long it will take since I'm working in a team that need timelines. Thanks!

...selected as the route along which the ride-sharing vehicle travels. The problem in the case is that the probability of picking up a user on the safe route is low, and efficient operation may not be possible. 　To solve this problem, in this technology, routes with a high probability of picking up users is selected when the sum of the recognition level values of each sensor (ex. camera, millimeter wave radar and LiDAR) mounted on the vehicle is higher than the reference value. This increases the likelihood that the ride-sharing vehicle will pick up many users. Furthermore, since the sensor's recognition level is also higher than the reference level, safety is ensured during the ride. Please search for this technology in this contest. <<NOTICE>> The target car bran...

...are much cheaper to maintain than unhealthy ones. 13. Ill health begets ill health. If you let a condition go untreated, or if you are generally unhealthy, you increase your chances of getting even more unhealthy. And, this gets more and more expensive in the long run. 14. Healthy diets are cheaper. Diets low in sugary soda, fatty meat and creamy desserts are significantly cheaper. Lentils, pure water and home grown veg cost just a few cents and are much better for you. 15. Healthy people can stay productive for longer. Making money takes energy, so healthy energy levels are often necessary. If you cultivate good healthy habits, you can keep earning money later in life. 16. Unpaid sick leave can be awful.
