For a side project, I turned to Wikipedia tables as a data source. Despite their inconsistencies, they proved quite useful. I explored three methods for extracting this data: - Google Sheets: Easily scrape tables using the =importHTML function. - Pandas and Python: Use pd.read_html to load tables into dataframes. - Beautiful Soup and Python: Handle more complex scraping, such as extracting data from both tables and their preceding headings. These methods simplify data extraction, though some cleanup is needed due to inconsistencies in the tables. Overall, leveraging Wikipedia as a free and accessible resource made data collection surprisingly easy. With a little effort to clean and organize the data, it's possible to gain valuable insights for any project.…

We’re building teams internally to enable as many developers and partners as possible to use Llama, and we’re actively building partnerships so that more companies in the ecosystem can offer unique functionality to their customers as well. I believe the Llama 3.1 release will be an inflection point in the industry where most developers begin to primarily use open source, and I expect that approach to only grow from here.

This article shows us two, at the first glance, distinct examples of c++ temporary lifetime extension (TLE) feature behavior. The one where we extend temporary lifetime through polymorphic reference conversion and the one where we do it through bounding a field of a temporary directly to a reference. However, if you look deeper you will see that in some context these two examples are similar. And therefore the feature behavior in both cases should be the same. The consistency is an important aspect of any design which helps users use the feature and temporary lifetime extension can show it on its own example.…

It provides a way to create and manage condition variables. It has methods to wait for, signal, and broadcast conditions. By using `sync.Cond`, you can write more controlled and synchronized concurrent programs in Go. It's important to note that sync.Cond is just one of the synchronization primitives provided by the Go standard library, and its usage depends on the specific requirements of your concurrent program. In some cases, other synchronization primitives like channels or sync.WaitGroup might be more suitable.…
