2. Altered states of consciousness induced by breathwork accompanied by music (journals.plos.org)

The popularity of breathwork as a therapeutic tool for psychological distress is rapidly expanding. Breathwork practices that increase ventilatory rate or depth, facilitated by music, can evoke subjective experiential states analogous to altered states of consciousness (ASCs) evoked by psychedelic substances. These states include components such as euphoria, bliss, and perceptual differences. However, the neurobiological mechanisms underlying the profound subjective effects of high ventilation breathwork (HVB) remain largely unknown and unexplored. In this study, we investigated the neurobiological substrates of ASCs induced by HVB in experienced practitioners. We demonstrate that the intensity of ASCs evoked by HVB was proportional to cardiovascular sympathetic activation and to haemodynamic alterations in cerebral perfusion within clusters spanning the left operculum/posterior insula and right amygdala/anterior hippocampus; regions implicated in respiratory interoceptive representation and the processing of emotional memories, respectively. These observed regional cerebral effects may underlie pivotal mental experiences that mediate positive therapeutic outcomes of HVB.

3. Open Source is one person (opensourcesecurity.io)

The Register recently published a story titled Putin on the code: DoD reportedly relies on utility written by Russian dev. They should be ashamed of this story. This poor open source developer is getting beat up now to score some internet points. It’s very upsetting. But anyway, let’s look at some receipts. If you’re not real smrt, it seems like pointing out an open source project is written by one person in a country you don’t like is a bad thing. It could be. But it also could be the software running THE WHOLE F*CKING PLANET is written by one person. In a country. But we have no idea which country. It’s not the same person mind you, but it’s one person.

网站防护系统Anubis说明

该页面显示是因为网站管理员部署了Anubis系统,用以保护服务器免受AI公司大规模爬取造成的负载压力。这种爬取行为会导致网站停机,使资源无法被正常访问。

Anubis是一种折衷方案。它采用类似Hashcash(曾用于减少垃圾邮件的方案)的工作量证明机制。在个体层面,附加的计算负载可忽略不计,但对于大规模爬取行为,这些成本会累积,显著提高爬取代价。

该系统目前是一个临时性解决方案,旨在为更高级的识别技术争取开发时间。长期目标是通过分析字体渲染等行为特征来识别无头浏览器,从而避免向普通合法用户展示挑战页面。

请注意,Anubis依赖现代JavaScript功能,类似JShelter的浏览器插件可能会禁用这些功能。建议在该域名下暂时禁用此类插件。

26. The Math Behind GANs (2020) (jaketae.github.io)

Generative Adversarial Networks refer to a family of generative models that seek to discover the underlying distribution behind a certain data generating process. This distribution is discovered through an adversarial competition between a generator and a discriminator. As we saw in an earlier introductory post on GANs, the two models are trained such that the discriminator strives to distinguish between generated and true examples, while the generator seeks to confuse the discriminator by producing data that are as realistic and compelling as possible.
