Linux kernel debugging
Linux kernel debuggingJungMinSEO5
?
The document discusses ways to determine where functions in a Linux kernel module are called from without using a debugger like JTAG or KGDB. It presents two methods:
1. Using the GCC built-in function __builtin_return_address(0) inside a macro to print the return address and lookup the calling function symbol. This shows the direct caller but may only show one level in ARM.
2. Calling the dump_stack() function, which prints a stack trace like panic() does. This can show the full call sequence back to the initial caller. The example prints the calls to a test module's init and exit functions.
Both methods allow determining the direct and indirect callers without an externalWhat is row level isolation on cassandra
What is row level isolation on cassandraKazutaka Tomita
?
Cassandra provides row-level isolation where a transaction is atomic for a single query executed on one node. A transaction in Cassandra updates either all columns in a row or none of them. Complex multi-row or multi-query transactions are not supported. The implementation uses a copy-on-write approach utilizing a concurrent data structure called SnapTree to clone columns being updated, ensuring atomic and isolated updates at the row level for a single query.Gevent rabbit rpc

Here are some suggestions to improve the test method name:
- shouldReturnNullWhenQueryReturnsNull
- shouldPassNullFromDaoWhenQueryReturnsNull
Using "should" makes the intent clearer - we expect the method to return null under certain conditions. Describing those conditions ("when query returns null") in the name provides more context than a generic "testQuery".
Overall, test method names should clearly communicate what is being tested and under what conditions we expect the test to pass or fail. This helps readers understand the purpose and focus of each test.code for quiz in my sql

1. The document discusses good and bad practices for writing unit tests. It emphasizes that tests should verify the expected behavior, fail clearly when something goes wrong, and use mocks and isolation to focus on the code being tested.
2. Some examples of bad tests shown include tests that don't make assertions or assertions that don't provide useful information on failure. Real objects are also used instead of mocks, obscuring the test.
3. Good practices include using mocks to isolate the code being tested, making sure tests fail clearly when something goes wrong, and focusing tests on expected behavior through clear assertions. Automated testing, fixing broken tests, and mastering testing tools are also emphasized.Construire une application JavaFX 8 avec gradle

Scrollable Demo AppPeeyush Ranjan
?
This Java program demonstrates scrollable functionality by creating a GUI with labels, text fields, and buttons to navigate a student database stored in an Oracle database. The program connects to the database, executes a query to retrieve student records, and populates the GUI fields as the "First", "Previous", "Next", and "Last" buttons are used to scroll through the result set. When a button is clicked, the action listener method retrieves the current student's data from the result set and displays it in the text fields.Net Beans Codes for Student Portal
