Claros inTouch是基于java的开源Web2.0邮件客户端，常和Apache James MailServer及MySql、Tomcat联合使用构建开源的WebMail邮件服务。Claros inTouch的最新版是Devel 2.2Beta版，这个版本较之前的2.1版增加了许多新的功能，我按照网上搜索到的帖子在企业内部网络部署WebMail服务时发现了一些错误，经过摸索最终解决了问题。
1、inTouch2.2beta版和mySql5.1版结合使用时，出现数据库读写错误，但inTouch2.1就不存在问题。
阅读源码发现，inTouch使用了名为MrPersister的对象持久化组件来实现后台数据库的读写，在inTouch2.1版和inTouch2.2版中，MrPersister组件的版本不同，使用新版本的MrPersister组件和mySql5.1数据库配合就存在数据库个别字段读写问题，因此导致Intouch2.2和mySql5.1结合使用时出现错误，这应该是inTouch升级时遗留的Bug。在不必修改源代码的情况下，用inTouch2.1中旧版本的mrpersister.jar文件覆盖Intouch2.2中的相应组件jar包，就可以解决此问题。
2、inTouch的WebMail邮件客户端界面上有很多错别字，应该是系统汉化时不严谨所致，需要修改，修改WEB-INF/classes/org/claros/intouch/i18n目录下的lang_zh_cn_utf8.properties文件中的相关内容就可以了，需要注意的是该文件中的汉字使用的是Unicode-ASCII Escaped格式，也就是/u前导符加上汉字的Unicode码的转换ASCII码，需要用UltraEdit这样的编辑器编辑。
3、邮件服务器James中设定使用mySql管理邮件存储空间，默认情况下收发大附件会导致系统错误，经查询是因为mySql默认数据包大小是1M，超过1M的附件就会导致数据库读写错误，在my.ini文件mysqld段中加入：max-allowed-packet=32M就可以解决此问题。
4、inTouch设计目标只是一个简单可用的WebMail的客户端，因此不包括邮件服务器的web界面管理，所以，也就没有用户邮箱注册、修改用户密码等功能，必须由邮件服务器James的管理员通过命令行管理用户，很不方便。然而用户注册和密码修改恰恰是Webmail服务必要的功能，从James源码看，可以有三种途径进行用户管理：一是从外部通过socket连接James服务器，发送James命令串管理用户；二是使用James源码构建用户管理类；三是使用jdbc直接读写James的users数据库进行邮件用户管理。考虑到工作量和复杂性，最终采用了第三种方法管理用户并提供Web页面的用户邮箱注册和用户密码修改功能。
以上2、4点的修改文件已打包成一个补丁包，在此下载【

Ten recommended open source free text annotation tools
Mar 26, 2024 pm 08:20 PM
Text annotation is the work of corresponding labels or tags to specific content in text. Its main purpose is to provide additional information to the text for deeper analysis and processing, especially in the field of artificial intelligence. Text annotation is crucial for supervised machine learning tasks in artificial intelligence applications. It is used to train AI models to help more accurately understand natural language text information and improve the performance of tasks such as text classification, sentiment analysis, and language translation. Through text annotation, we can teach AI models to recognize entities in text, understand context, and make accurate predictions when new similar data appears. This article mainly recommends some better open source text annotation tools. 1.LabelStudiohttps://github.com/Hu
15 recommended open source free image annotation tools
Mar 28, 2024 pm 01:21 PM
Image annotation is the process of associating labels or descriptive information with images to give deeper meaning and explanation to the image content. This process is critical to machine learning, which helps train vision models to more accurately identify individual elements in images. By adding annotations to images, the computer can understand the semantics and context behind the images, thereby improving the ability to understand and analyze the image content. Image annotation has a wide range of applications, covering many fields, such as computer vision, natural language processing, and graph vision models. It has a wide range of applications, such as assisting vehicles in identifying obstacles on the road, and helping in the detection and diagnosis of diseases through medical image recognition. . This article mainly recommends some better open source and free image annotation tools. 1.Makesens

Recommended: Excellent JS open source face detection and recognition project
Apr 03, 2024 am 11:55 AM
Face detection and recognition technology is already a relatively mature and widely used technology. Currently, the most widely used Internet application language is JS. Implementing face detection and recognition on the Web front-end has advantages and disadvantages compared to back-end face recognition. Advantages include reducing network interaction and real-time recognition, which greatly shortens user waiting time and improves user experience; disadvantages include: being limited by model size, the accuracy is also limited. How to use js to implement face detection on the web? In order to implement face recognition on the Web, you need to be familiar with related programming languages and technologies, such as JavaScript, HTML, CSS, WebRTC, etc. At the same time, you also need to master relevant computer vision and artificial intelligence technologies. It is worth noting that due to the design of the Web side
The source code of 25 AI agents is now public, inspired by Stanford's 'Virtual Town' and 'Westworld'
Aug 11, 2023 pm 06:49 PM
Audiences familiar with "Westworld" know that this show is set in a huge high-tech adult theme park in the future world. The robots have similar behavioral capabilities to humans, and can remember what they see and hear, and repeat the core storyline. Every day, these robots will be reset and returned to their initial state. After the release of the Stanford paper "Generative Agents: Interactive Simulacra of Human Behavior", this scenario is no longer limited to movies and TV series. AI has successfully reproduced this scene in Smallville's "Virtual Town" 》Overview map paper address: https://arxiv.org/pdf/2304.03442v1.pdf
