mysql blob的简单学习 Blob的优点在于不理会存储文件的类型,图片、文件、压缩包都按照二进制文件来处理存储;
缺点在于如果存储了超大文件(比如多媒体文件之类的),数据库的效率肯定会受影响。 mysql blob分为四种类型,如下(大小单位为字节): TinyBlob 255 Blob 65k MediumBlob 16M LongBlob 4G 如果要存储超大文件,最好还是存储到服务器中,只在数据库中保留路径。
或者将文件信息和文件内容分别存储在两个表中,只在需要读取文件内容的时候才查询操作文件内容表。 摘自 wkupaochuan的专栏 bitsCN.com

When trying to open a disk image in VirtualBox, you may encounter an error indicating that the hard drive cannot be registered. This usually happens when the VM disk image file you are trying to open has the same UUID as another virtual disk image file. In this case, VirtualBox displays error code VBOX_E_OBJECT_NOT_FOUND(0x80bb0001). If you encounter this error, don’t worry, there are some solutions you can try. First, you can try using VirtualBox's command line tools to change the UUID of the disk image file, which will avoid conflicts. You can run the command `VBoxManageinternal

The impact of data scarcity on model training requires specific code examples. In the fields of machine learning and artificial intelligence, data is one of the core elements for training models. However, a problem we often face in reality is data scarcity. Data scarcity refers to the insufficient amount of training data or the lack of annotated data. In this case, it will have a certain impact on model training. The problem of data scarcity is mainly reflected in the following aspects: Overfitting: When the amount of training data is insufficient, the model is prone to overfitting. Overfitting refers to the model over-adapting to the training data.

Git is a fast, reliable, and adaptable distributed version control system. It is designed to support distributed, non-linear workflows, making it ideal for software development teams of all sizes. Each Git working directory is an independent repository with a complete history of all changes and the ability to track versions even without network access or a central server. GitHub is a Git repository hosted on the cloud that provides all the features of distributed revision control. GitHub is a Git repository hosted on the cloud. Unlike Git which is a CLI tool, GitHub has a web-based graphical user interface. It is used for version control, which involves collaborating with other developers and tracking changes to scripts and

Bad sectors on a hard disk refer to a physical failure of the hard disk, that is, the storage unit on the hard disk cannot read or write data normally. The impact of bad sectors on the hard drive is very significant, and it may lead to data loss, system crash, and reduced hard drive performance. This article will introduce in detail the impact of hard drive bad sectors and related solutions. First, bad sectors on the hard drive may lead to data loss. When a sector in a hard disk has bad sectors, the data on that sector cannot be read, causing the file to become corrupted or inaccessible. This situation is especially serious if important files are stored in the sector where the bad sectors are located.
