4 min readTo upgrade the PowerShell version from 2.0 to 3.0, you will first need to download and install the Windows Management Framework 3.0. This package includes updates to PowerShell, along with other components such as the .NET Framework.Once the Windows Management Framework 3.0 is installed, you can open PowerShell and check the version by typing $PSVersionTable.PSVersion. This will confirm that you are now using PowerShell 3.0.

4 min readTo get all attributes of a matplotlib plot, you can use the __dict__ method to access the dictionary of attributes associated with the plot. By calling plot.__dict__, you can see all the properties and their values that are available for the matplotlib plot object. This will allow you to inspect and modify various attributes such as color, line style, labels, and more. This can be useful for customization and debugging purposes when working with matplotlib plots in Python.

3 min readTo create an alias to format-table in PowerShell, you can use the New-Alias cmdlet. You can create a new alias by specifying the current alias (ft) and the command (Format-Table) that you want to alias. For example, you can create an alias called "ft" for the Format-Table command using the following command:New-Alias ft Format-TableOnce you have created the alias, you can use it in your PowerShell scripts and commands just like you would use the Format-Table command.

4 min readTo remove multiple strings from a PostgreSQL string column, you can use the REPLACE function in combination with the || operator to concatenate strings. First, identify the strings you want to remove from the column. Then, use the REPLACE function to replace each of these strings with an empty string. You can do this in a single query by chaining multiple REPLACE functions together using the || operator.

6 min readTo call a jQuery function from PowerShell, you can use the Invoke-WebRequest cmdlet to make an HTTP request to the page that contains the jQuery script. You can then use the Invoke-RestMethod cmdlet to execute the jQuery function and retrieve the result. Alternatively, you can save the jQuery script locally and use the Add-Type cmdlet to load the script and call the functions directly. Remember to include the necessary dependencies and make sure that jQuery is loaded before calling the function.

5 min readTo increase the plottable space above a subplot in matplotlib, you can adjust the overall figure size or the relative height of the subplot. One approach is to create a new subplot that takes up the desired amount of space at the top of the figure, leaving the necessary space above the existing subplot. You can also adjust the spacing between subplots using the subplots_adjust() function.

6 min readTo run a PowerShell script in Maven, you can use the Maven Exec Plugin. This plugin allows you to execute command-line programs, including PowerShell scripts, from within your Maven project.To use the Maven Exec Plugin, you need to add it to your project's pom.xml file and configure it to run your PowerShell script. You can specify the path to the PowerShell executable and the path to your script file in the plugin configuration.

6 min readTo implement a cache table in PostgreSQL, you can create a new table in your database that will store frequently accessed or computationally expensive information. This cache table can be updated periodically or in real-time based on your application's needs. You can use triggers, views, or stored procedures to manage the cache table and keep it in sync with the primary data source.
-
3 min readTo retrieve the raw figure data from Matplotlib, you can use the fig.canvas.get_renderer().buffer_rgba() method. This method will return a numpy array representing the raw RGBA values of the figure. You can then manipulate this data as needed for further analysis or processing. Keep in mind that this method may not be suitable for very large figures due to memory constraints.

![How to Get Characters Between [ ] In Postgresql? preview](https://cdn.blogweb.me/1/66f0320047ebdb7c7ce172fb_d457f7378d.png)
3 min readIn PostgreSQL, you can extract characters between square brackets by using the substring function along with regexp_matches.Here's an example query that demonstrates how to achieve this: SELECT substring(regexp_matches('This is [an example] text with [characters] in brackets', '\[(.*?)\]', 'g')[1] FROM dual; In this query, the regexp_matches function is used to extract all substrings that match the pattern \[(.*?)\] (anything between square brackets).
