7 min readTo use freetype bindings in Rust, you first need to include the freetype crate in your project's dependencies. You can do this by adding the following line to your Cargo.toml file: freetype = "0.7.1" Once you have included the freetype crate, you can use it in your code by importing the necessary modules.

3 min readTo see the default values in a table in Oracle, you can query the USER_TAB_COLS view. This view contains information about the columns in all tables that are accessible to the current user. When querying this view, you can look at the DATA_DEFAULT column to see the default value defined for each column in the table.

5 min readTo unload a Keras/TensorFlow model from memory, you can use the del keyword to delete the model object. This will release the memory used by the model. For example, if you have a model object named model, you can simply do del model to unload it from memory. This is especially useful when you have limited memory resources and need to free up memory after using a model. Additionally, you can also clear the TensorFlow session using keras.backend.

5 min readTo connect to an Oracle database from a .NET application, you can use the Oracle Data Provider for .NET (ODP.NET) or the Oracle.ManagedDataAccess.dll. First, make sure you have the necessary Oracle client software installed on your machine. Then, you can create a connection string in your .NET application that specifies the necessary information, such as the server name, database name, username, and password. Next, you can use the OracleConnection class in .

7 min readIn TensorFlow C++, the run() function is used to execute a specific operation within a TensorFlow graph. This function takes a Session object and a list of Operation objects as arguments, and it runs the specified operations within the session.When you call the run() function, TensorFlow will automatically execute the necessary computations to produce the outputs of the specified operations.

6 min readTo get an array of field values from an array of structs in Rust, you can use the iter method in combination with the map method. By iterating over each struct in the array, you can extract the desired field value and collect them into a new array. Additionally, you can use closures to specify which field value to extract from each struct. This approach allows you to efficiently transform the array of structs into an array of field values according to your requirements.
-
3 min readTo get the sum of timestamps in Oracle, you can use the INTERVAL data type along with the SUM() function. By converting timestamps to intervals, you can perform addition operations on them. For example, you can add intervals representing seconds, minutes, hours, etc., to get the desired sum of timestamps. Remember to handle any date components separately if needed.[rating:dc3bb8f1-bf14-46f8-a39b-16fc925c6a8c]What is the recommended way to sum timestamp data in Oracle.

5 min readTo unload a Keras/TensorFlow model from memory, you can use the tf.keras.backend.clear_session() function in TensorFlow. This function clears the current computational graph and frees up the memory occupied by the model. Additionally, you can also delete any references to the model object and call the Python del keyword to remove the model from memory. By doing so, you can ensure that the memory used by the model is released and made available for other tasks.

3 min readTo convert from local timezone to UTC in Rust, you can use the chrono crate. First, you need to create a DateTime object representing the time in your local timezone. Then, you can use the .with_timezone() method to convert it to UTC. Here is an example code snippet: use chrono::{DateTime, Local, Utc}; fn main() { let local_time = Local::now(); let utc_time = local_time.with_timezone(&Utc); println!("Local time: {:?}", local_time); println!("UTC time: {:.

5 min readTo get the ID of the last row inserted in Oracle, you can use the RETURNING clause in your INSERT statement. This clause allows you to retrieve the value of the column that was just inserted.
-
5 min readTo feed Python lists into TensorFlow, you first need to convert them into a TensorFlow tensor object. This can be done using the tf.constant method, which creates a constant tensor from a Python list. Once the list is converted into a TensorFlow tensor, you can feed it into your TensorFlow model as input data. Alternatively, you can use the tf.data.Dataset API to create a dataset from the Python list and then feed the dataset into your model.
-
7 min readTo return a result data type in Rust, you can use the Result enum. The Result enum has two variants: Ok and Err. When a function successfully returns a value, you can wrap that value with the Ok variant. If there is an error, you can wrap the error with the Err variant.
