How do you profile Go code for performance?

How do you profile Go code for performance?

Go code performance analysis can be implemented through the built-in pprof tool. First, import the debug endpoint to enable the \_"net/http/pprof"; 1. For HTTP services, start the pprof interface of localhost:6060 in the program; 2. Use gotoolpprof http://localhost:6060/debug/pprof/profile?seconds=30 to collect 30 seconds CPU performance data; 3.

How does SQL handle NULL in a comparison (e.g., WHERE column = NULL)?

How does SQL handle NULL in a comparison (e.g., WHERE column = NULL)?

Special attention is required when handling NULL values in SQL, because NULL represents unknown or missing values and does not follow conventional comparison logic. 1. Use ISNULL to check the NULL value, because =NULL will not take effect, it will return UNKNOWN; 2. Be careful when using NOTIN. If the subquery contains NULL value, the entire condition may return UNKNOWN. Use NOTEXISTS instead or filter NULL; 3. Aggregation functions such as COUNT, SUM, and AVG will ignore the NULL value, COUNT(*) counts all rows, and COUNT(column) only counts non-NULL values. Understanding these rules helps avoid common pitfalls in query results.

How to use Bootstrap forms?

How to use Bootstrap forms?

The key to using Bootstrap forms is to master its structure and use of classes. 1. The basic form structure uses form-control, form-label, form-text and form-check to style input, label, help text and check boxes; 2. Horizontal forms are displayed in line with labels and controls by combining grid systems (such as col-sm-*), and inline forms use practical classes such as d-flex to replace the removed form-inline in Bootstrap5; 3. Form verification uses is-valid or is-invalid classes to match valid-feedback and invalid-feedback to display inversely.

How to resample time-series data using pandas in Python?

How to resample time-series data using pandas in Python?

To resample the time series data in pandas, you must first make sure that the data has a datetime index, and then use the .resample() method to specify the frequency and apply the aggregation or fill method; 1. For downsample (such as hour to day), use aggregation functions such as df.resample('D').mean(); 2. For upsample (such as day to hour to hour), use df.resample('H').ffill() or .interpolate() to fill the missing values; 3. Multiple aggregate functions or custom functions can be applied through agg(); 4. The closed and label parameters can be adjusted to control interval closure and label alignment, and finally achieve accurate frequency conversion.

What are function arguments and how do you use them in Python?

What are function arguments and how do you use them in Python?

Python function parameters are values passed in when calling a function. They are used to customize function behavior to make them reusable and flexible; when defining a function, specify parameters, and pass in the actual value of the corresponding parameter when calling, that is, parameters; parameter types include: 1. Position parameters, passed in order, and parameter assignment is determined in order; 2. Keyword parameters, assign values through parameter names, order irrelevant; 3. Default parameters, set default values when defining, and can be omitted when calling; 4. Variable length parameters, args receive any number of position parameters, *kwargs receive any number of keyword parameters; when using it, variably default parameters should be avoided, and the use of parameter types is recommended to improve the clarity and maintainability of the function.
