SQLite with two python processes accessing it: one reading, one writing
I’m developing a small system with two components: one polls data from an internet resource and translates it into sql data to persist it locally; the second one reads that sql data from the local instance and serves it via json and a restful api.
Not await an asynchronous method because it is like an endless loop – good practice?
I inherited a piece of software. This program is connected to an external hardware, which is a measurement device. Every 100 milliseconds, a value is read from this device and displayed to the user. When the user clicks a button, this continuous measurement is interrupted and no value will be displayed to the user anymore. Some action is done and when this action is finished, the program starts to take the measurement values again. In the code, this realized like this:
Best Practices for Handling Currency Calculations in SQL Databases
I’m dealing with currency calculations in my application, and I’ve noticed that decimal operations are rounded by default (e.g., 0.126 becomes 0.13). When performing operations like multiplications between different currency values, is it better to truncate the results before saving them to ensure accuracy? What are the best practices for handling such calculations in SQL databases to maintain precision and correctness? Any advice or guidance would be helpful. Thank you!
Pros and Cons of throwing vs throttling w.r.t. rate limiting
When it comes to rate-limiting a web service there are two approaches:
Concurrent programming – min, max problem
Here is a simple program in CoPascal:
Editing files without race conditions?
I have a CSV file that needs to be edited by multiple processes at the same time. My question is, how can I do this without introducing race conditions?
