On October 22, according to CCTV News, China’s first self-developed 10 MW advanced compressed air energy storage system, after 4,000 hours of test operation, was officially connected to the grid for power generation in Bijie, Guizhou. Significant progress has been made in the field of energy technology.

It is reported that this set of advanced compressed air energy storage system technology and equipment are independently developed by China. It has the characteristics of large scale, low cost, long life, not restricted by geographical conditions, and environmentally friendly. It is an energy storage that can be promoted on a large scale. technology. The system compresses and stores the air when the electricity load is low at night, and then releases the high-pressure air to drive the generator to generate electricity at the peak of the day. A maximum of 40,000 kWh of electricity can be generated per day, which is equivalent to the electricity consumption of 3000 households a day. Played the role of power grid peak shaving.

According to Guo Wenbin, an engineer from the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the storage medium of this system is air only, and there is no risk of sudden explosion. The air pressure storage range belongs to the medium pressure range, and the risk is controllable.

The system is successfully connected to the grid for power generation, which can not only enhance the power grid's ability to regulate peak and valley power loads, but also store unstable wind power, photovoltaic power generation and other new energy sources, which is equivalent to the grid "stabilizer" and "battery".

10 月 11 日消息 今天微信 iOS 版迎来 8.0.15 更新，官方提供的更新内容跟上个版本相同，为“可开启「关怀模式」，文字与按钮更大更清晰”。

据网友测试，新版本安装之后系统监控已经看不到微信读取相册的记录。之前有网友 @Hackl0us 发现微信等应用“在用户未主动激活 App 的情况下，在后台数次读取用户相册，每次读取时间长达 40 秒 至 1 分钟不等”。针对此事，微信方面回应称：iOS 系统为 App 开发者提供相册更新通知标准能力，相册发生内容更新时会通知到 App，提醒 App 可以提前做准备，App 的该准备行为会被记录成读取系统相册。最新版本中将取消对该系统能力的使用，优化快速发图功能。

据 @Hackl0us 称，关于微信的图片选择器，微信官方已经确认对该功能进行改进。不会再在后台进行任何预处理，而是会改用子线程的方式，在点击按钮的瞬间去调取相册最后一张图片。
