After following, you can keep track of his dynamic information in a timely manner
This article aims to resolve the TypeError: create() got an unexpected keyword argument 'api_type' error encountered by the AutoGen framework when using native large language models such as LM Studio. This error originates from AutoGen that has removed the support for the api_type parameter in config_list to maintain the latest compatibility with the OpenAI API. The tutorial will provide detailed configuration update steps to guide users to correctly configure local LLM and ensure that the AutoGen agent is running normally.

The window.open() method is used to open a new window, but attempting to inject HTML or JavaScript code into windows of different sources (cross-domain) is strictly limited by the browser's homologous policy. This policy is designed to prevent malicious script attacks and ensure user data is secure. Therefore, the content of the cross-domain page opened by window.open() cannot be directly modified or accessed by the parent page, and the WindowProxy object only provides full interactive capabilities under homologous conditions.

This article deeply explores the security limitations of the window.open() method in JavaScript when dealing with cross-domain content. We will explain in detail why it is impossible to directly modify or inject scripts after opening a page of a different source through window.open(), which is mainly due to the same-origin policy strictly followed by the browser. The article will explain the core principles of homologous policies and their impact on WindowProxy objects and provide relevant examples to help readers understand this critical security mechanism.

When RSA encrypts a byte stream (such as image data), directly using BigInteger.toByteArray() will convert the encrypted BigInteger into a variable-length byte array. When these variable-length arrays are simply spliced and written to a file, the decryption end cannot accurately identify the boundaries of each encryption block, resulting in data misalignment and decryption failure. The core solution is to append its length information before each encryption block, ensuring that the original BigInteger can be read correctly and reconstructed during decryption.

A few weeks ago, my Windows 11 computer started to get severely stuttered. After inspection, it was found that OneDrive took up a lot of local storage space. Fortunately, I successfully freed up disk space by setting all OneDrive files to keep only cloud copies. The following are the specific operation methods. What is OneDrive’s “On-Demand Files” feature? OneDrive provides a feature called Files On-Demand. When enabled, you can see all the synced OneDrive files on your computer, but these files do not actually take up local storage, but are retained in the cloud. As the name implies, when you need to access a file,
