  • 核心评论:

    • alluro2：I was blown away by M1 Pro, and used it for 4 years before it became a little sluggish, and replacing it with an Asus S16 running on Ryzen AI 9 HX 370 (an excellent laptop). One of the main reasons was missing my old Linux setup. I’ve briefly tested M5 Pro in an Apple store and w…
    • bayindirh：I know, this is a bit of a meaningless comment, but it’s funny in a way. Feels like late 90s again: - Xiaomi: We have matched Apple in CPU performance. - Apple: Meep Meep…
    • recursivedoubts：Even w/the pricing spike, inflation adjusted we are back to roughly the prices of a new Mac SE/30 for something that can beat a turing test w/o sweating. I yield the floor to no one when it comes to pessimism, but that’s incredible.

  • 核心评论:

    • joshstrange：Due to pricing insanity (not that Apple prices weren’t insane before the ram/ssd shortages) I’m not in the market but I do wonder if my next computer should be a Mac Studio instead of a MBP that lives its life docked. Might be better to just run a Studio and Neo for the very few …
    • osmukka：Reading this press release was almost physically painful, because of how much Apple loves to use the phrase “up to”. In total it appears 46 times.
    • blints：10 grand for 256GB memory. Likely double that for 512GB, but won’t be available or finalized until October. Thunderbolt 5 is highest bandwidth external IO available at 120Gb/s. 1.2TB/s claimed max internal memory bandwidth. Not exactly “future proof” for >1T parameter models but …

  • 核心评论:

    • madrox：A friend died of diabetic ketoacidosis. He loved technology and seeing people succeed. Thinking of him with this news. Miss you Dan. Grateful we’re moving forward on so many fronts in the world.
    • ijustlovemath：Automated glucose control will be the next frontier in so many areas of healthcare. I’m still skeptical that anyone will be able to noninvasively and accurately sense blood sugar, but I’m glad people (especially kids with T1) will have one more tool to help them. I hope they can …
    • umvi：Ketones are only going to be present if you are exceptionally bad (very high carb diet) or exceptionally good (very low carb diet) at managing your blood sugar. It’s not going to be terribly useful for your average diabetic who has fairly good control over their blood sugars.

  • 摘要: OpenAI Jalapeño: Better than Nvidia Blackwell

  • 核心评论:

    • mchusma：I think they talked about this being general purpose chip but I would think that Anthropic/OpenAI are at the scale now they could bake LLM weights into chips themselves. For example, GPT Sol baked into a custom chip run for $100M that runs 10x as fast and 10x as cheap should pay …
    • corford：These nascent inference chip efforts are reminding me of the early 3dfx / riva / mach / powervr days. Will be interesting to see if inference chips are here to stay and, if so, who the eventual dominant player(s) will be

  • 摘要: Python’s pre-declared constants are kinda weird

  • 核心评论:

    • hmokiguess：Python is awful. There are so many one offs in libraries, none agree on a style, it’s slow, and it’s way too easy to do the wrong thing. I often work with data scientists and have to productionize their jupyter notebooks which is pure suboptimal hell. I guess it must be a good ea…

    • neillyons：I remember reading that in early versions of Python there was no built in True and False. Each user would implement this themselves as True = 1 False = 0 then later these got added to the language. In Python 2 you could still reassign and swap them so that ‘if False’ was actually…

  • 摘要: Black hole singularity is a surface not a point

  • 核心评论:

    • sigmoid10：Should be pointed out that this is a critique of common popsci journalism tropes and not a fancy new research result. Anyone who has taken a graduate level class in General Relativity would have been able to tell you the same.
    • Certhas：As is nicely visualised by it’s Penrose Diagram, e.g. https://jila.colorado.edu/~ajsh/insidebh/penrose_schw.gif

  • 核心评论:

    • kccqzy：I copy-pasted a random LaTeX doc from many years ago (I made sure I wrote it before 2020 so it did not use any new features not in TeX Live 2020), and upon compilation I got the error Font OT1/cmr/m/n/10.95=cmr10 at 10.95pt not loadable: Bad metric (TFM) file. on line 13017. The …

  • 摘要: When str.lower() is a security vulnerability in Python – Seth Larson

  • 核心评论:

    • echoangle：> This is why calling str.lower() represents a difference in the implementation and the specification, and therefore a vulnerability: I wish there was some explanation how this is a vulnerability and not just a bug generating erroneous data. Vulnerability for me sounds like there…
    • tialaramex：This idiocy is a big part of why it was so important to get Python people working on TLS implementations to understand that the defined mechanism for SANs (no the “alternative” in Subject Alternative Name doesn’t mean in the sense of more than one, X.509 is originally for the X.5…

  • 摘要: C2PA Cameras Do Not Survive Contact with Reality

  • 核心评论:

    • randomblock1：Even at the hardware level, if it was a separate chip that the camera data passed through or something, that’s not really good enough either, people have broken TPMs before. It’d have to be baked into the camera sensor. Even then, you could attack it from the next level up, with …
    • uqers：I’m very surprised Google put in so much effort to implement an approach that is basically the equivalent of client-side verification of passwords. Did no one designing it mention that it could be defeated by any rooted device?

    • jdoe1337halo：So happy with my base M4 purchase for $499 when it released. I even snagged a 1TB replacement drive for $199 a year ago. Feels like I got the last train out.
    • Ambroos：It’s a bit of an emotional goodbye to the super cheap Mac Minis we got to enjoy for a while. I got some for family members, we had some serving as iOS/macOS build servers sitting in a closet at my last job, they were fantastic. Not that they’re a bad deal now, but at European pri…
    • daveisfera：One of the things that Steve Jobs got very right was “and you can order right now”. Announcements where you have to wait a month to order throw away all of the hype. Even allowing pre-orders and shipping later is a better idea and so silly that Apple has started walking away from…

  • 摘要: Show HN: I made a Raspberry with Qwen my local car AI

  • 核心评论:

    • ehnto：Fair warning, I have found local models and frontier models to be very bad at the specifics when it comes to cars. Small differences like month and year model can impact oil capacity, oil weight and things like that, the details that matter quite a bit. I found frontier models co…
    • Robdel12：I will shamelessly plug https://pitstop.app . I’ve been working on this for years and I work on/race cars regularly. I wouldn’t fully trust LLMs with this :p BUT this project is still really freaking sweet.
    • Reubachi：I’m currently integrating one for simple diagnostic readouts to integrated small touchscreen. The main goal being a retro looking display that mainly dumps ODB data/monitors, but also reads maps data to show a “waypointer” a la crazy taxi. (This is proving difficult) Respectfully…

  • 深度解读: 本地大模型部署正成为技术社区的热点议题。本文指出，很多『模型变笨』的体验并非权重本身的问题，而是量化、KV缓存、推理框架和硬件差异导致的实现陷阱。评论中用户对 Q8 量化、MLX 框架和 Ollama 的争论，反映了社区在追求可访问性与性能之间仍在摸索最佳实践。

  • 摘要: Run OpenBSD on DigitalOcean for $4/month

  • 核心评论:

    • bananamogul：That pricing is awful. $4/month for 512MB VPS…eeek. You’ll find much better pricing at RackNerd, DediRock, InterServer, BuyVM, etc. Small indy hosting companies are the way to go. 2GB for $5/month or so is the typical price point. Any host that offers KVM and allows you to uplo…
    • dchest：A warning about openbsdhandbook[.]com - this website has completely incorrect information for some things. Like hallucinated, even though I think it was created before LLMs.
    • 8by3：I’ve always gone with Vultr (vultr.com) for BSD VMs, its properly supported by them and while I’ve never hard verified this, they seem like a nice smaller player. Like they have offered Open/Free BSD VM’s for > 10 years, kind of nice.

  • 深度解读: 这篇 2005 年的邮件既是技术史，也是个人叙事。社区反响集中在两个层面：开源操作系统如何改变个人职业轨迹，以及 NetBSD 在稳定性与可移植性上的长期口碑。怀旧情绪背后，是对『自己动手理解系统』这一黑客精神的持续认同。

    • wlaw15：Sometimes you learn of an unintended consequence of seemingly good idea wreaking havoc on an ecosystem. I would not put fishing with “plastic bottles filled with explosives” into that category.
