NumPy is the core library for scientific computing in Python. It is good at handling linear algebra operations and provides efficient ndarray arrays and functions in the numpy.linalg module. 1. Use np.linalg.solve(A,b) to solve the linear equation system Ax=b to obtain the solution vector x; 2. Matrix transposition is implemented through A.T; 3. Matrix multiplication can be used to np.dot(A,B) or A@B; 4. Matrix inverse is calculated by np.linalg.inv(A), and the matrix needs to be reversible; 5. The determinant is given by np.linalg.det(A); 6. The eigenvalue and eigenvector are obtained through np.linalg.eig(A), and the eigenvector has been normalized;

Use routing prefix for version control, and use Route::prefix('v1') in routes/api.php to group routes through Route::prefix('v1'); 2. Organize the controller by version into directories such as app/Http/Controllers/Api/V1, etc. to keep the code clear; 3. Optionally use AcceptHeader version control to parse the version information in the request header through middleware; 4. Use LaravelAPIResource to customize response structures for different versions, such as V1/UserResource and V2/UserResource; 5. When the old version is deprecated, the user should be notified in advance and the Deprecated response header should be added through middleware.

First, check and turn off the overclocking settings. 1. Enter BIOS/UEFI to restore the default settings or use IntelXTU, AMDRyzenMaster and other tools to cancel the overclocking; 2. Update or roll back the firmware and drivers, including upgrading the BIOS, installing the latest chipset drivers and Windows updates, and uninstalling the latest updates if necessary; 3. Test the hardware stability, run Prime95 or AIDA64 for CPU stress test, use HWMonitor to monitor the temperature, check whether the power supply is stable, and re-plug and unplug the CPU, memory, power cord and other hardware to try to minimize system startup; 4. You can try to disable the core stop or power management functions, such as switching the high-performance power plan through the command line, or

You can set, shortcut keys, and extend the behavior of custom VSCode QuickOpen, but you can't completely rewrite its core logic. 1. Use search modifiers such as @ (current file symbol), # (global symbol), : (jump line number), @: (symbol line number), ext: (filter by extension) and ? (help) to filter and sort results. You can use it in combination such as @function. 2. Configure "files.exclude" and "search.exclude" in the settings to exclude node_modules, dist and other files. .gitignore or .ignore files will also be affected.

When using uintptr and unsafe packages, it is necessary to ensure that the object pointed to by the pointer is not garbage collected or moved, and is only used for underlying operations if necessary; ?Safe practices include type conversion using unsafe.Pointer, pointer arithmetic with uintptr in a single expression, and immediate return to unsafe.Pointer after pointer arithmetic with uintptr, and priority use of unsafe.Slice and unsafe.String of Go1.20; ?Hidden practices include converting local variable addresses to uintptr and returning, calling uintptr across functions, and creating slices with reflect.SliceHeader; ultimately, prioritize whether there is no unsa or not.

Use make to initialize slices, maps, and channels to make them available non-nil values; 2. Use new to allocate zero-value memory for any type and return a pointer to it, but it is usually only used when a zero-value pointer is needed; 3. Make returns the type itself, while new returns a pointer to the type; 4. In actual development, make should be used to process slices, maps, and channels, while new is less used. It is recommended to use structure literals instead of new initialization structures.

To create the Bootstrap5 drop-down menu, you need to first introduce the Bootstrap's CSS and JS files, and then build the structure using specific classes and data attributes. 1. Introduce BootstrapCSS and JS through CDN in HTML; 2. Create drop-down buttons, use the .dropdown-toggle button, and data-bs-toggle="dropdown" attribute, and add .dropdown-menu and .dropdown-item to build menu items; 3.

Install the BIND package; 2. Configure the named.conf file to allow query and recursion; 3. Create forward zone files and define A records; 4. (Optional) Create reverse zone files to support PTR records; 5. Set correct file permissions and SELinux context; 6. Enable and start named services; 7. Configure the firewall to allow DNS traffic; 8. Use named-checkzone, named-checkconf and dig to test the configuration; 9. Point the client DNS to this server; each time you modify the zone file, you need to increment the serial number. It is recommended to configure the DNS server from the DNS server and disable public recursion to ensure security. After all steps are completed, the DNS server will run normally.
