  • 量子计算领域即将爆发的重磅消息 Quantum computing bombshells

    For those of you who haven’t seen, there were actually two “bombshell” QC announcements this week. One, from Caltech, including friend-of-the-blog John Preskill, showed how to do quantum fault-tolerance with lower overhead than was previously known, by using high-rate codes, which could work for example in neutral-atom architectures (or possibly other architectures that allow nonlocal operations, like trapped ions). The second bombshell, from Google, gave a lower-overhead implementation of Shor’s algorithm to break 256-bit elliptic curve cryptography.
    如果你还没注意到，本周量子计算领域实际上有两项“重磅”公告。一项来自加州理工学院，包括本博客好友约翰·普雷斯基尔在内， 他们展示了如何利用高速率码以比以往更低的开销实现量子容错 ，这项技术可以应用于中性原子架构（或者其他允许非局域操作的架构，例如囚禁离子）。另一项重磅公告来自谷歌， 他们提供了一种开销更低的肖尔算法实现 ，可以破解 256 位椭圆曲线密码。

  • DRAM 的价格正在扼杀业余爱好者的单板计算机市场。 | DRAM pricing is killing the hobbyist SBC market

    Unless the DRAM pricing situation changes radically, I think the hobbyist SBC market is dying—or at least on life support. And I don't just mean Raspberry Pis, but all SBC vendors. LPDDR chips now account for the majority of board cost from the vendors I've checked with.
    除非 DRAM 价格出现根本性变化，否则我认为业余爱好者的单板计算机（SBC）市场正在走向衰亡——或者至少是苟延残喘。我指的不仅仅是树莓派，而是所有 SBC 厂商。据我了解，LPDDR 芯片现在占据了主板成本的大部分。

    怎么说呢，心情复杂，内心划过好多想法。深刻感受到地球资源是有限的。

  • Gemma 4 发布，支持文本、音频和图片输入

    • Gemma 模型概览

      Gemma 是一系列先进的轻量级开放模型，其开发采用了与 Gemini 模型相同的研究成果和技术。 Gemma 由 Google DeepMind 和 Google 的其他团队共同开发，其名称源自拉丁语 gemma，意为“宝石”。Gemma 模型权重受开发者工具支持，这些工具可促进创新、协作和负责任地使用人工智能 (AI)。

  • Qwen3.6-Plus

    Qwen3.6-Plus 的 API 通过 阿里云百炼 提供服务，主要特性包括：

    • 默认支持100万上下文窗口
    • 显著提升的智能体编程能力
    • 更出色的多模态感知与推理能力

    林走后，新官上任的第一把火？似乎没有开源？

  • The Beginning of Programming as We'll Know It | 我们所知的编程的开端

    Speaking of goodness, I share the majority opinion that AI is generally good. That is to say that I believe it will prove to have a positive impact on humanity. It will accelerate productivity in virtually every field, lead to insights in science and medicine, and offer accessibility advantages to millions of people. And yes, it will inevitably “take the jobs” of many unsuspecting victims. But as I hinted earlier, the suspecting victims all stand to gain. So be … suspectful? That doesn’t sound right. But be wary.
    说到“善”，我赞同大多数人的观点，认为人工智能总体上是好的。也就是说，我相信它将对人类产生积极的影响。它将提高几乎所有领域的生产力，为科学和医学带来新的见解，并为数百万人带来便利。没错，它不可避免地会“抢走”许多毫无防备者的饭碗。但正如我之前提到的，所有对此有所怀疑的人最终都会从中受益。所以，保持警惕？这话听起来不太对劲。但还是要保持警惕。

    A mantra I’ve been repeating to myself lately is that an AI’s code can not be counted as “work” until a human has reviewed it and fixed any problems. If we’re going to talk about computers replacing humans, then the “work” that is done has to meet or exceed the standard that humans have set. We have these standards not just because we’re fussy, but because they lead to less buggy, higher performance, and more maintainable code. They’re not going to take our jobs by writing unreadable functions that are 4-times as long and defy platform conventions. Once they’ve completely taken over, they can write the code however they like. But for now, they need to abide by human standards.
    最近我一直在提醒自己，人工智能的代码只有经过人类审查并修复问题后才能算作“工作成果”。如果我们要讨论计算机取代人类的问题，那么它完成的“工作成果”必须达到甚至超过人类设定的标准。我们制定这些标准并非出于苛求，而是因为这些标准能够带来更少的 bug、更高的性能和更易于维护的代码。人工智能不会通过编写冗长到四倍、难以阅读且违反平台规范的函数来抢走我们的工作。一旦它们完全接管了我们的工作，它们就可以随心所欲地编写代码。但就目前而言，它们必须遵守人类的标准。

    And so I repeat that mantra, because I don’t want to fall into the same trap that I’m sure many programmers already have: committing AI-generated code without review. And when I say I don’t want to fall into that trap, I mean I don’t want to fall into that trap again. Or at least not too many more times. Or not too often.
    所以我反复强调这一点，因为我不想落入许多程序员已经落入的陷阱：未经审查就提交人工智能生成的代码。我说不想落入这个陷阱，是指我不想再次落入这个陷阱。或者至少不要再多次落入。或者不要太频繁地落入。

    我也一样，ai的力量非常容易使人沉沦，有点像恶魔契约啊（笑）。

    The time may come, perhaps even soon, when AI takes over programming completely. But in the mean time, a programmer who embraces AI, yet is skeptical about everything it creates, is better-equipped than any comparably-skilled human in programming history. I’ve written specifically about programmers, but I think this also applies to writers, artists, musicians, and people in every other profession whose products can be described by any stretch as “creative work.” Anybody who maintains strict control over the final product may find that AI enhances, rather than replaces, their creativity. The computers will come for all of our jobs eventually, but those of us who refuse or decline to embrace the most powerful creative tools we’ve ever been given will be the first to fall.
    或许不久的将来，人工智能就会完全取代编程。但在此之前，一位既拥抱人工智能又对其创造的一切保持怀疑态度的程序员，比编程史上任何技能相当的人类都更有优势。我曾专门撰文探讨过程序员，但我认为这同样适用于作家、艺术家、音乐家以及其他所有从事“创意工作”的人。任何对最终作品保持严格控制的人都可能发现，人工智能增强而非取代了他们的创造力。计算机最终会取代我们所有人的工作，但那些拒绝或不愿接受我们所拥有的最强大的创造工具的人，将首当其冲。
