此消息一出，有网友拍手叫好 近日，有消息称，微信正在优化聊天记录备份的功能，支持U盘等多种存储设备。对此，微信方面回应 称，正小范围测试聊天记录备份功能优化。 微信表示，和当前仅支持备份到电脑相比，优化后的功能支持用户通过手机微信，将聊天记录备份到外 部存储设备（如U盘、移动硬盘），且可创建及管理多份备份文件，并支持自动备份。目前，该功能更 新在持续扩大测试范围。 聊天记录备份的具体路径是"微信设置-通用-聊天记录与迁移-备份与恢复"，如果你的微信在该功能的灰 度测试范围，那么就会看到现在备份与恢复可以选择"备份到电脑、U盘等多种存储设备"或"支持自动 备份"。 备份范围可以选择全部聊天或者指定聊天，也可以选择指定时间段。此外，用户还可开启自动备份，支 持电量不足20%时暂停备份，以节省手机电量。 网友评论 推荐阅读 点击标题可跳转 1、 GitHub 第 10 亿个仓库封神了！官方祝贺认证，全球程序员笑翻！ 2、 神操作！中国工程师拖 4 箱硬盘 80TB 数据飞国外训练 AI、 3、 12 年首次大改！真有人喜欢苹果的"液态玻璃"吗？至少 Flutter 开发者的噩梦开始了 也有网友期待出更多新功能 你怎 ...

为什么 JPEG 仍然统治着网络？ 三十年前， JPEG 成为我们在互联网上分享数码照片的主要方式 1. 引言 近三十年来，JPEG 一直是万维网的主流图像格式。但它并非网络最初的选择。事实上，首款主流图形浏览器 NCSA Mosaic 最初并不支持嵌入式 JPEG 文件——只支持嵌入式 GIF，以及其他几种已被历史遗忘的格式。然而，JPEG 相比其迅速取代的格式具有诸多优势。 当时 Ernie Smith 在 Tumblr 上转发了这段采访（那时 Tumblr 正是 GIF 的"宇宙中心"）。很快，这条帖子被转发数千次，几乎所有人都在反驳威尔特。 不久后，他的这段话甚至成了网络迷因。 这个故事折射出威尔特（2022 年去世）的创作模式：他并非通过委员会协作开发格式。正因如此，他可以自行定义发音。1987 年，作为 CompuServe 员工的他接到开发任务，独自完成了这个产品。最初描述其工作原理的文档？简单到极致。三十八年后的今天，我们仍在使用 GIF，但它从未达到 JPEG 的普及程度。 而大约五年后正式诞生的 JPEG 则完全不同。两者的差异，本质是"事实标准"与"正式标准"的区别，而这正是 JPEG ...

Core Viewpoint - The Trump Group's launch of the T1 smartphone and Trump Mobile service is seen as an expansion into the tech sector, but it raises questions about the authenticity of its "Made in America" claims, as the products are primarily manufactured in China [4][6][24]. Group 1: Trump Mobile Overview - Trump Mobile is marketed as a "next-generation wireless service provider" offering "top-notch network connectivity" and "unparalleled value," primarily targeting Trump supporters [4][6]. - The service operates as a mobile virtual network operator (MVNO), relying on major carriers like AT&T, Verizon, and T-Mobile for network access [8]. - The flagship plan, named "47 Plan," is priced at $47.45 per month, which includes unlimited calls, texts, and data, with the first 20GB at high speed [10][12]. Group 2: T1 Smartphone Details - The T1 smartphone is claimed to be "designed and manufactured in America," but it is essentially a rebranded Chinese Android device, with a price mark-up of three times its original cost [6][18][22]. - The T1 features a 6.8-inch AMOLED display, 256GB storage, and runs on Android 15, but all components are imported, raising doubts about its "American-made" status [16][17][24]. - The T1 is priced at $499, with a $100 deposit for pre-orders, while similar models are available on Amazon for around $180 [18][22]. Group 3: Manufacturing and Supply Chain Issues - The claim of "American manufacturing" is questioned, as key components like the display and camera modules are sourced from overseas, and the production of chips is also outsourced [24][25][28]. - Assembling smartphones in the U.S. is challenging due to high costs and reliance on imported parts, making it unlikely for the T1 to be genuinely American-made [27][28]. - The pricing strategy suggests that the T1 may be a low-margin product, potentially compromising quality to maintain a competitive price point [28].
