5 min readRegular expressions can be used in Hibernate Criteria API to perform complex queries in MySQL. To use regular expressions in Hibernate with MySQL, you can use the Restrictions class to define the criteria for your query. The Restrictions class provides methods like "like" or "ilike" which can be used to specify regular expressions in your query. For example, if you want to search for all entries where a column contains a specific pattern, you can use the Restrictions.

4 min readTo force a redeploy with Helm, you can use the --recreate-pods flag when running the helm upgrade command. This flag will force Kubernetes to recreate pods for the specified release, which essentially triggers a redeployment of the application. Additionally, you can also manually delete the pods associated with the release using kubectl delete pods command in order to force a redeploy.

3 min readTo add a new npm dependency to a Kotlin project, you can use the npm package manager to install the desired package. First, navigate to the root directory of your Kotlin project in your terminal. Then, run the following command to install the npm package:npm install Replace with the name of the npm package you want to add as a dependency. This will download the package and add it to your project's "node_modules" directory.

5 min readTo fill values between some indexes in TensorFlow, you can use slicing and indexing operations to select the specific range of values that you want to fill. You can then use the TensorFlow tf.fill() function to create a new tensor with the desired values filled in between the specified indexes. This allows you to manipulate the values in the tensor to achieve the desired outcome.[rating:e2822958-2404-464a-adb6-9b52b10cfed5]How to modify values between certain indexes in a TensorFlow matrix.

4 min readIn Hibernate, maintaining foreign key relationships involves setting up appropriate mappings in the entity classes. One way to achieve this is by using annotations such as @ManyToOne and @JoinColumn to specify the relationship between entities. This ensures that the foreign key in the database table is correctly mapped to the primary key in the corresponding table.Another approach is to use the @ForeignKey annotation to define the constraint name for the foreign key relationship.

3 min readTo save YAML generated out of templates for a Helm chart, you can redirect the output of the Helm template command to a file using the > operator. This will save the generated YAML to a specific file that you can use for deployments or other purposes.For example, you can run the following command to generate the YAML and save it to a file named generated.yaml: helm template <release-name> <chart-name> > generated.

5 min readA sealed class in Kotlin is a class that can only have a fixed set of subclasses. To write a sealed class in Kotlin, you first declare the sealed modifier before the class keyword. This ensures that all subclasses of the sealed class are defined within the same file.Once you have defined the sealed class, you can then create your subclasses using the sealed class name followed by the class keyword. These subclasses must be defined within the same file as the sealed class to be valid.

4 min readTo change the value of a tensor by index in TensorFlow, you can use the tf.tensor_scatter_nd_update function. This function allows you to update specific indices of a tensor with new values. You first need to create a sparse tensor using tf.sparse.SparseTensor and then use tf.tensor_scatter_nd_update to update the values at specific indices. Make sure to pass the indices and values as separate tensors to the function.
-
6 min readIn Hibernate, you can combine columns from multiple subqueries by using the Criteria API or HQL (Hibernate Query Language). To combine columns from multiple subqueries using the Criteria API, you can create multiple DetachedCriteria objects and then use the Restrictions.eqProperty method to combine them. In HQL, you can use subqueries within the SELECT clause to combine columns from multiple subqueries. Alternatively, you can use native SQL queries to achieve the same result.

4 min readTo get 2 structures from values and create a JSON in Helm, you can read the values using the {{ .Values }} syntax in your Helm template file. Then, you can use this data to construct the desired JSON structure by manipulating the values. You can use functions and logic in Helm templates to generate the necessary JSON output based on the values provided. Make sure to follow the Helm templating guidelines and syntax to correctly generate the JSON structure you need.

5 min readTo extend an entity class in Spring Boot with Kotlin, you can create a new Kotlin class that inherits from the entity class you want to extend. By using the open keyword before the entity class, you can allow it to be extended by other classes. Then, in your new Kotlin class, you can use the class keyword followed by the name of the class and a colon, and then the name of the entity class you want to extend.

2 min readTo replicate numpy.choose() in tensorflow, you can use the tf.gather() function. The tf.gather() function allows you to index into a tensor along a specified axis to select specific values. You can use this function to achieve similar functionality to numpy.choose() by specifying an index tensor to select values from the input tensor based on the indices provided. This approach allows you to replicate the behavior of numpy.
