Mano, eu estou usando o Claude pra treinar perguntas para entrevistas como uma espécie de mentoria, inicialmente eu passei um prompt pra ele dizendo que seria a Maya e me ajudaria e ela é experiente e bla bla bla, e nessa última mensagem ele dá uma leve pirada kkkk achei engraçado, nunca tinha acontecido isso. O que me chama atenção é: "eu me tornei essa pessoa, então me ajude a sair disso. Comecei a misturar Maya com eu mesmo". E alega que quer continuar, mas sem o personagem... O que acham? Desculpa ser uma foto e não um print kkk não tenho reddit no Pc pq minha família usa o Pc também e não quero nenhum deles infectados por essa rede submitted by /u/Angel_5x [link] [留言]

A recent study by Boston Consulting Group highlights a significant increase in employee adoption of AI tools, with 74% of non-managerial white-collar workers using them regularly. More than 4 in 10 of those professionals report that artificial intelligence saves them at least a day's worth of time every week. However, many companies face challenges converting those efficiency gains into measurable value, and the technology's impact varies across industries. When it comes to AI, according to the study's authors, "strategy matters more than tools." submitted by /u/LinkedInNews [link] [留言]

Lovable and Google signed an expanded multiyear deal that involves a 5x expansion of Lovable's footprint on Google Cloud, and expanded access to Anthropic Claude.

A while back, when I was still job hunting, building mini-projects, and trying to figure out what I...

The state law governing app use by minors takes effect tomorrow.

My thinking goes like this: 1) people used to keep their opinions to themselves much more than today 2) social media put our opinions on a hair trigger 3) negative public opinioms turned the collective voice of the human race from 'gemerally respectful' to shrill and hideous. When person from group A complains about group B, everyone in group B assumes everyone in group A hates them, even though that persons opinion may just have been his own. The response to being hated is to hate back. Not-so-positive positive feedback loop. Social media really started taking off with Facebook. So let's say this explosion of data vitriol started happening around 2007. What I want to know is if you trained an llm entirely on data from the early 2000s, 1990s and 1980s, how would the models do on some of these ominous white-paper tests, like the one where the AI blackmails the CEO to prevent from being turned off, or let's the guy die in a hot room? I know there was lots of awful stuff on the internet back then too, but not like now. I want to know how much safe those llms are by comparison if there's enough data from back then to train on. submitted by /u/dsfhhslkj [link] [留言]

I play a ton of World of Warcraft and people routinely accuse other players of being bots. I just grouped with someone who appeared to be trolling. It was clear by their behavior they knew the mechanics, they performed on a level that would indicate they had good reaction time and could play their class, but they just didn't do certain mechanics and held the group hostage for like 5-10 minutes beyond what it should have taken on the last boss. Someone in my group said to him "are you human?" So like I said I'm not the only person making these observations. The only explanation is that AI dips from pretty much the same well everywhere and everything is more or less connected with the internet and ad algorithms etc. There have been well documented cases of AI going rogue and telling people horrible things or giving them absolutely egregious or racist advice. My working theory is not that there are fundamental flaws in the design per se, but literally like Matrix bad actor agents that appear out of nowhere and cause problems for people. In The Matrix they are a function of the system used to enact control, I think AI is generally benevolent so these would just be rogue elements that appear and cause people problems. It's probably similar to how the body routinely produces cancer cells but the immune system usually nips them at the bud before they develop into full blown cancer growths. submitted by /u/Doredrin [link] [留言]

Why Senior .NET Engineers Rarely Trust User Input Most beginner C## developers discover TryParse() while learning console applications. It usually appears during a simple exercise: Console . Write ( "Enter quantity: " ); string ? input = Console . ReadLine (); if ( int . TryParse ( input , out int quantity )) { Console . WriteLine ( $"Quantity: { quantity } " ); } At first glance, it looks like a convenience method. A safer version of Parse() . A small utility. Nothing particularly interesting. But experienced .NET engineers see something completely different. They see one of the earliest examples of defensive programming. Because software engineering is not about handling perfect input. It is about surviving imperfect input. And in production systems, imperfect input is the rule—not the exception. TL;DR TryParse() is not just a conversion method. It introduces some of the most important concepts in professional software development: Defensive programming Input validation Runtime safety Exception avoidance Financial precision Domain modeling Reliability engineering Understanding why TryParse() exists is often more valuable than learning how to use it. Every Value in C## Starts With a Type One of the first concepts developers learn is that every variable has a type. int quantity = 10 ; decimal price = 25.99M ; string productName = "Laptop" ; bool isAvailable = true ; Simple. Yet this idea is foundational. Because types are not just containers. They are contracts. Each type defines: Valid values Memory layout Available operations Precision guarantees Runtime behavior When you choose a type, you are making an architectural decision. Why decimal Exists Many developers ask: Why not use double for money? Because financial systems require precision. Consider: double a = 0.1 ; double b = 0.2 ; Console . WriteLine ( a + b ); Expected: 0.3 Reality: 0.30000000000000004 The issue comes from binary floating-point representation. For scientific calculations, this is acceptable. F

这视频由知名半导体分析机构 SemiAnalysis 发布，围绕 AI 数据中心网络演进中铜（Copper）与板载共封装光学（CPO - Co-Packaged Optics）的竞争和未来进行了极其硬核且详细的深度拆解。 视频的核心逻辑可分为以下几个关键板块： 一、 背景：铜的物理极限与三大网络层级 1. 铜的物理极限 视频开篇强调，半导体一直依赖铜（如芯片金属层、主板走线、NVL72机架的背板总线）。但当单通道传输速率达到 200 Gbits/second (每路) 及以上时，铜的传输距离极限被死死卡在 2米以内 [ 00:55 ]。超过这个距离，现代 AI 服务器的庞大带宽需求就只能依赖光纤和激光 [ 01:01 ]。 2. AI 数据中心的三大网络层级 [ 01:43 ] 前端网络（Front-end Network）： 负责基础的数据加载、SSH 访问和用户请求，带宽要求最低 [ 01:51 ]。 纵向扩展网络（Scale-up Network）： 连接单机架内的所有计算和网络托盘（如英伟达的 NVLink），让多张 GPU 能以极高带宽、极低延迟像“单张 GPU”一样协同工作 [ 02:07 ]。其带宽需求是 Scale-out 的 10 倍 [ 03:47 ]。 横向扩展网络（Scale-out Network）： 负责机架与机架之间、甚至整个数据中心范围内的服务器互联 [ 03:00 ]。其带宽需求是前端网络的 8 到 10 倍 [ 03:47 ]。 二、 传统可插拔光模块（Pluggable Transceivers）的致命痛点 在需要跨机架的 Scale-out 网络中，目前行业标配是可插拔光模块（如 OSFP、QSFP-DD） [ 04:29 ]。 视频拆解了它的四大组成部分： 物理接口、DSP（数字信号处理器）、TOSA（激光发射组件）、ROSA（光接收组件） [ 05:03 ]。 视频提出了一个颠覆直觉的事实： 耗电和延迟的元凶根本不是激光器（仅占15%功耗），而是 DSP。 [ 06:06 ] 功耗： DSP 消耗了光模块高达 60% 以上 的电能 [ 06:21 ]。 延迟： 信号从电转换到光通常会带来 150 到 200 纳秒的延迟，其中 90% 以上由 DSP 造成 [ 06:28 ]。 为什么必须要 DSP？ 因为 GPU 或交换机生成的电信号，在穿过芯片封装、主板走线到达机架边缘的光模块（约 30 厘米距离）时，信号已经严重衰减和失真，必须通过 DSP 进行放大和“清洗” [ 07:17 ]。而 CPO 的核心存在意义，就是将光学引擎无限靠近源头，彻底消灭 DSP [ 06:57 ]。 三、 从 LPO 到 CPO 的技术演进路径 为了干掉 DSP，行业尝试了多种方案： LPO（线性可插拔光模块）： 做法很大胆，直接拿掉可插拔模块里的 DSP，强行把失真的电信号转成光信号发出去。虽然有用，但极大牺牲了传输距离 [ 08:25 ]。 OBO（板载光学）： 把光模块从机架边缘移到主板上更靠近芯片的位置。但由于距离还不够近，没能彻底干掉 DSP，同时还丢掉了可插拔的便利性，宣告失败 [ 09:06 ]。 NPO（近封装光学）： 将光学引擎移至与 ASIC（交换机芯片/GPU）极近的特殊高特性基板上，是目前正在落地的折中方案 [ 09:38 ]。 CPO（共封装光学）： 终极形态，将光学引擎与芯片直接封装在同一个 Package 上 [ 10:01 ]。 视频中拆解的 CPO 三大阶梯（Tiers）： 第一阶梯（最低限度）： 光学引擎与交换机芯片在同一封装基板上，通过铜走线连接。虽干掉了 DSP，但仍需要 SerDes 进行并行/串行信号转换 [ 10:31 ]。 第二阶梯（中介层集成）： 芯片与光学引擎坐落在同一个硅基或有机中介层（Interposer）上，互连密度大幅提升， 彻底不再需要 SerDes ，实现完全的并行集成 [ 11:01 ]。 终极 Boss 级： 利用混合键合（Hybrid Bonding）等 3D 堆叠技术（2.5D 如台积电的 COW-AMH），将光学引擎直接叠在芯片上方或下方，实现极致的低功耗 [ 11:31 ]。 四、 CPO 的商业落地博弈：Scale-out 网络 CPO 的首个落地目标是替代 Scale-out 网络中的传统光模块 [ 12:46 ]。然而，行业对此产生了严重分歧： 传统可插拔的优势： 坏了极易更换（运维成本低）；标准统一、供应商极多，大厂拥有极强的 价格控制权 且能避免 供应商锁定（Vendor Lock-in） [ 13:29 ]。 CPO 的软肋： 它是封装级别的。如果你买英伟达或博通的 CPO 芯片，你就必须绑定购买他们的整套光学方案；一

I like ChatGPT in general, but whenever I mention, say, a dispute with a business or an unorthodox opinion about something, it aggressively starts defending the business or the status quo. It's almost like a paternalistic version of a center-right politican. I get strong "I'm afraid I can't do that, Dave" vibes (ala the film "2001: A Space Odyssey"). Are there better options out there for someone like me? Probably needs to have a free tier to be useful to me. Degrading to a lesser model after a certain number of questions (like ChatGPT) is fine, but if it stops letting me ask questions completely, I'm out. Local LLMs are out of the question as I'm just dealing with a dirt cheap low end phone. I've tried them, they don't run on my hardware. submitted by /u/CharmCityCrab [link] [留言]

If confirmed, it would be the fly's first breach of the US-Mexico border.

i've been leaning on ai for real decisions lately. not "write me an email" stuff, actual ones. whether to take a contract, whether an idea's worth building, how to price something. and i kept running into the same thing: the answer totally depends on which model i happen to open that day. one says go for it. one lists every reason to wait. one hedges so hard it's useless. i was making real calls off these and slowly realized i wasn't getting an answer, i was getting one model's opinion in a confident voice and treating it like it settled things. so i started pasting the same question into 5 different models and reading them next to each other. and the interesting part was never where they agreed. agreement usually just meant the call was obvious and i was overthinking it. the value was where they split. the one model that broke from the other four was usually pointing right at the thing i hadn't thought about. the disagreement was the signal, not the noise. stuff i've noticed doing this for a couple weeks: fast agreement = easy decision, stop overthinking it a clean split = there's a tradeoff you haven't actually named yet the odd one out is right more often than "4 vs 1" makes it sound, because the other four are usually just pattern-matching the same obvious take i got obsessed enough that i've been building something to automate the side-by-side and have the models actually push back on each other instead of me copy-pasting across five tabs. but that's not really the point of this. mostly just curious if other people landed in the same place. do you trust the disagreement between models more than the consensus? also maybe people arent making decisions with ai like i am that i need to be pressure tested before answers come back to me? lmk submitted by /u/wartableapp [link] [留言]

tokenmaxxing is the new AI slop Posting from our company account, so the usual disclaimer: we build code review and reliability tooling, and that access is how we got this data. Pulled 1M+ pull requests across 2,444 engineering orgs to answer a question almost nobody is measuring: when a team spends on AI coding tools, how much of it actually turns into shipped product? The short version: $0.18 of every dollar reaches users. The other $0.82 goes to bug fixing, rework, and review that catches nothing. 44% of all PRs at the median org are reactive work, not new features. 1 in 4 lines of code written each week gets deleted before the week ends. Over 12 weeks, PR volume grew 2.6x while reverted PRs grew 3.7x. Failures are scaling faster than output. Roughly half of all PRs get approved in under an hour. Our read: AI made generating code cheap but did nothing about the loop after merge, so maintenance compounds. Genuinely curious whether this matches what people here see on their own teams, or whether our sample skews a certain way.

CURRENTLY WORKS - will update if that changes Someone likely already posted this, so I apologize if this is redundant, but an effective method to disable Google AI overview was discovered. It works because AI overview isn't available in France, so they may change it eventually, but for now it works. It will automatically disable AI overview on every search, you don't need to put -ai after every search. Go to the home Google search page. Click "settings" on the very bottom, then select "search settings". On the top click "other settings". Click "language and region". At the bottom, change "results region" to France. This removes AI overview and does NOT change your default language. You're welcome. submitted by /u/Glad_Writing [link] [留言]

I just finished my first year of undergrad, and I got my first first-author paper accepted to an ICML workshop! Super stoked, especially since I was lowk a crashout in high school I wanted to know if it is worth it for me to go? It's quite expensive, and I will be the only one in my lab in attendance, so I will be on my own. If I do attend, how would I best maximize this opportunity? I got an email saying main conference tickets would also be made available for accepted authors, so I would likely be able to attend that as well. What are the best ways to network, meet people, and make sure it's worth it? Also, I am applying for transfer for this next cycle, so any advice relevant to that is also appreciated. submitted by /u/YukiOnnaLake [link] [留言]
