BitTorrent 不再是上行流量之王
2024-03-19 18:06 by 乌鸦从高塔坠落
Web 2.0 时代前的 2004 年，BitTorrent 流量曾占到整个互联网流量的 35%。当时 P2P 文件共享是主要的流量来源。20 年后的今天，视频串流服务如 YouTube、Netflix 和 TikTok 杀死了昔日的流量之王。即使是盗版视频网站，BitTorrent 也不再是主流，大部分盗版视频网站也是基于串流。BitTorrent 协议的一大功能是上传，过去十年它在互联网上行流量中仍然占据不小的份额，2013 年占到了所有上行流量的三分之一，但 2021 年降至了 10%。加拿大宽带管理公司 Sandvine 本周公布的报告显示，BitTorrent 在几乎所有类别中都不占优。视频和社交媒体是下行流量的主要驱动力，BitTorrent 在上行流量中占 4%，被云存储应用、FaceTime、Google 和 YouTube 超越。今天的 BitTorrent 流量是由少数做种共享文件的用户产生的。

CRISPR-Cas 基因编辑在实验室中完全消除 HIV 病毒
2024-03-20 18:41 by 猿朋豹友
荷兰阿姆斯特丹大学的研究人员报告，他们利用 CRISPR 基因编辑技术，成功的从受感染细胞中消除了 HIV 病毒。HIV 治疗的重大挑战之一是该病毒具有将自身基因组整合到宿主 DNA 中的能力，尽管目前有多种有效的抗病毒药物用于治疗 HIV 感染，但只能抑制 HIV 在人体内的复制，无法将其清除，故患者需要接受终身抗病毒治疗，因为一旦抗病毒治疗停止，HIV 可能会卷土重来。HIV 可以感染体内不同类型的细胞和组织，每种细胞和组织都有其独特的环境和特征。在这项研究中，荷兰研究人员使用“分子剪刀”与两种 gRNA（向导 RNA） 来对抗所有已知的 HIV 毒株中保持相同的病毒基因组部分，并成功治愈了 HIV 感染者的 T 细胞。荷兰研究人员证明，当在培养皿中的免疫细胞上进行测试时，他们的 CRISPR 系统可以灭活所有 HIV 病毒，将其从免疫细胞中清除。研究人员强调他们的工作仍然只是“概念证明”，不会很快成为 HIV 的治疗方法。

Show HN: Memories – FOSS Google Photos alternative built for high performance (🔥 Score: 160+ in 3 hours)
Link: https://readhacker.news/s/64xYH
Comments: https://readhacker.news/c/64xYH
Memories is a FOSS Google Photos alternative that you can self-host (it runs as a Nextcloud plugin).
Website: https://memories.gallery/
GitHub: https://github.com/pulsejet/memories
Demo Server: https://demo.memories.gallery/apps/memories/
(demo runs in San Francisco on a free-tier cloud vm)
Memories has been built ground-up for high performance and is extremely fast when configured correctly. In our testing environment, it can load a timeline view with 100k photos in under 500ms, including query and rendering time!
Some features to highlight:
* A timeline similar to Google Photos where you can skip to any time in history instantly.
* AI-based tagging that runs locally on your server, identifying and tagging people and objects.
* Albums and external sharing.
* Metadata editing support
* A world map of your photos, supported both on mobile and the web
* Did I mention it's extremely fast?
Would love to hear feedback from the HN community! :)

DuckDB as the New jq
Recently, I’ve been interested in the DuckDB project (like a SQLite geared towards data applications). And one of the amazing features is that it has many data importers included without requiring extra dependencies. This means it can natively read and parse…

虽然不知道为什么，但是 YouTube 推荐算法最近把这个空客祝波音 100 年诞辰的视频推到各种奇怪的地方。
感觉更缺德了。
