我在 Solana 中文名活动中获得了奖金，我会按照承诺将奖金赠送给中国朋友们。 Thrilled about projects like @trendsdotfun launching a drive to give a chinese name for @solana China's crypto scene is a powerhouse, huge market, unbeatable community vibes. As an open and inclusive blockchain, solana's got that perfect synergy with them, so a tailored chinese name just makes sense Drawing inspo from solana foundation president @calilyliu 's post, my crew and I whipped up 索拉拉 (suolala), a fierce, long-haired builder chick channeling her energy. She's the embodiment of everyone hustling on solana, turning it into this boundless hub of innovation The solana ecosystem's on fire now: defi, payfi, socialfi, RWAs, perps, ICM, infofi, memecoins, nfts. You name it, build it. Organic growth, killer infra, endless potentia Shout out to all the solana builders like 索拉拉(suolala) Increase Bandwidth, Reduce Latency

$ATH 价格下探 从二级市场的价格来看，IVC跟罗卫宇会进一步把 $ATH 的价格砸到0.0068-00034 U 这个区间. 罗卫宇跟IVC@ivcryptofund  正不断做空砸盘 $ATH ，一同在做空的还有 @nanren 。 账户资产这半个月应该涨疯了。  $ATH Price Plunge From the perspective of the secondary market, IVC  and Luo Weiyu are likely to further drive down the price of $ATH to the range of $0.0068–$0.0034 usdt IVC  @ivcryptofund  and Luo Weiyuare continuously  shorting and dumping $ATH, with @nanren also participating in the shorting. Their account assets have likely surged dramatically over the past half-month. $ATH 가격 하락 2차 시장의 가격 관점에서 볼 때, 로웨이위(罗卫宇)는 $ATH의 가격을 $0.0068~$0.0034 usdt 구간으로 더 끌어내릴 가능성이 높습니다. 로웨이위와 IVC 는 계속해서 $ATH를 공매도하고 가격을 떨어뜨리고 있으며, @nanren도 공매도에 동참하고 있습니다. 그들의 계좌 자산은 지난 반달 동안 엄청나게 상승했을 것입니다. @HouseofChimera  @andrewmoh  @SidDegen   @heungmangoo  @VuoriTrading  @0xLofty  @DeFiTracer  @TheCryptoYapper   @wacy_time1  @AltCryptoGems  @coinmuhendisi  @Morecryptoonl  @0xFinish  @scribble_dao  @intern_cripto @anshitaksoni   @Bancrypto__ @Edward__Park @Coiniseasy @cryptocruise77  @RaoniKor  @Bum_cryptotiger  @SuperteamKorea  @tm_uchal  @co_cobling   @Hope_web3_   @munchanghw98379  @Bounty_ATM   @Jongyun_s_korea @with_blockmedia @tokenpostkr @CoinNess_ @bloomingbit_io @thehellolabs @riyuexiaochu @monkeyjiang  @liuxiaoling933  @leshka_eth @BTC_Alert_  @wublockchain12  @octopusycc  @sjbtc9   @superogers1  @YeruiZhang @0xNathanWalk  @ferdie_jhovie #ath# #ivc# #罗卫宇#

夏奇拉一直是我心目中的哥倫比亞女神 這國家是選美皇后生產國之一 曾許願有生之年能解鎖這國家的女生 這次終於如願 拉丁小隻馬 — 🇨🇴 Elena @cruz4_u 原本計劃要單約 但排定見面的那天 她剛好月經亂期 時間會強碰 原先地點也離彼此比較近 但她很有誠意的說 為了跟我見面 她請男友提前幾天 開4.5小的車來找我 她說：這樣就你就可以享用我了 (我欣賞這種直接的說話方式) 先吃飯聊天熟悉彼此 隔天一早約在他們退房前 享受早晨陽光跟蟲鳴鳥叫 男友看著看著，最後還是受不了 加入戰局讓她吃到飽 Sexy petite colombiana — Elena She and her man drove 4.5 hours just to let me use her, I was flattered by how warm and enthusiastic they were. Her boyfriend got really turned on watching her ride me, Eventually, he felt she enjoyed two cocks more than him staying on the sidelines. @ToBulaer @ToBuerma @KawasawaSen @BulmaList #watta# #chudai#

#GM# DAT假利好 罗卫宇跟Aethir 所搞得DAT ，都只是更好出货的幌子而已。 需要重点说明下: ATH这次的DAT收割局，核心推动者除了罗卫宇以外，还有 IVC@ivcryptofund。 可以说，IVC是躲在Aethir 背后的另外一把大镰刀。 DAT False Hype The DAT promoted by Luo Weiyu and Aethir is merely a pretext for easier cash-outs. It’s crucial to emphasize: For this round of ATH’s DAT harvest scheme, besides Luo Weiyu, the core driver is IVC @ivcryptofund. IVC is the other big sickle hiding behind Aethir. DAT 거짓 호재 로웨이위(罗卫宇)와 에테르(Aethir)가 추진하는 DAT는 단지 더 쉽게 현금화하기 위한 구실에 불과합니다. 특히 강조해야 할 점은: 이번 ATH의 DAT 수확 계획에서 핵심 추진자는 로웨이위 외에도 IVC(@ivcryptofund)입니다. IVC는 에테르 뒤에 숨어 있는 또 다른 큰 낫이라고 할 수 있습니다. @HouseofChimera  @andrewmoh  @SidDegen   @heungmangoo  @VuoriTrading  @0xLofty  @DeFiTracer  @TheCryptoYapper   @wacy_time1  @AltCryptoGems  @coinmuhendisi  @Morecryptoonl  @0xFinish  @scribble_dao  @intern_cripto @anshitaksoni   @Bancrypto__ @Edward__Park @Coiniseasy @cryptocruise77  @RaoniKor  @Bum_cryptotiger  @SuperteamKorea  @tm_uchal  @co_cobling   @Hope_web3_   @munchanghw98379  @Bounty_ATM   @Jongyun_s_korea @with_blockmedia @tokenpostkr @CoinNess_ @bloomingbit_io @thehellolabs @riyuexiaochu @monkeyjiang  @liuxiaoling933  @leshka_eth @BTC_Alert_  @wublockchain12  @octopusycc  @sjbtc9   @superogers1  @YeruiZhang @0xNathanWalk  @ferdie_jhovie #aethir# #ath# #ivc# #罗卫宇# #dat#

和Quant Alex @StochAlex07 讨论： SABR Theta与Spot Theta+Vol Theta+Cross Theta的异同与应用，以及SABR模型自洽性分析。 **English Summary of the Chat** **SABR Theta vs Spot Theta + Vol Theta + Cross Theta** The conversation between **Alex Wu** (white bubbles) and **Jeff Liang** (green bubbles) is a technical discussion focused on **SABR Theta versus Total Theta** (i.e., Spot Theta + Cross Theta + Vol Theta), model self-consistency, PDE residual, and the correct definition of SABR Greeks. ### Key Points Discussed: 1. **SABR Gamma = Spot Gamma** (first major question, raised by Jeff) Jeff asked whether SABR Gamma (\(\partial^2 P / \partial F^2\)) is identical to Spot Gamma and whether it includes the dependence of \(\sigma_B\) on \(F\). He also provided the full chain-rule expansion of SABR Gamma in terms of Black-76 Greeks. Alex confirmed the understanding and **later affirmed in code** that this is exactly how SABR Gamma is implemented in their system. 2. **SABR Theta vs Total Theta and Model Self-Consistency** (main topic, led by Jeff) Jeff shared a clear 3-point understanding: - SABR Theta is computed directly via the SABR approximation formula to obtain \(\sigma_B\), then applying the Black-76 chain rule: \(\partial P/\partial t =\) BS_Theta(\(\sigma_B\)) + BS_Vega \(\cdot \partial\sigma_B/\partial t\). - Total Theta is the exact decomposition from the SABR PDE (Spot Theta + Cross Theta + Vol Theta). - When the model is **fully self-consistent** (Residual = \(\partial P/\partial t + \mathcal{L}P = 0\)), SABR Theta = Total Theta; otherwise the difference is the unexplained PnL caused by the approximation error in the Hagan formula (especially pronounced in long-dated, high vol-of-vol, or high-skew options). 3. **Practical Implication – Theta Decomposition Decision** (comment by Alex) Alex noted that whether to perform Theta decomposition depends on the risk-management approach: - Without decomposition → use SABR Gamma vs. dP/dt. - With decomposition → SABR Gamma maps to Spot Theta, Vanna to Cross Theta, and Volga to Vol Theta. **Overall Tone**: The discussion is highly technical and collaborative. Jeff drives the conversation by asking clarifying questions and presenting a well-structured 3-point summary of his recent study. Alex provides confirmations, practical insights, and code-level validation. Both participants demonstrate a strong command of SABR model nuances, particularly the relationship between approximation error, PDE residual, and real-world risk management.

一文看懂AI数据中心大周期下的功率半导体 的下一场军备竞赛，不再只是GPU，而是Power AI 数据中心正越来越大，一个数据中心耗能动辄相当于一座中型城市。 过去的数据中心是 10-20kW/rack，现在已经变成 80kW、120kW，甚至 600kW/rack。大型 AI Cluster 的耗电已进入 GW 级别。 瓶颈除了GPU、cpu和储存，也开始转向电流、热、配电、铜损、电力转换效率、电网接入和 HVDC。 AI 数据中心产业链： 电网 → 变压器 → UPS → HVDC → PSU → VRM → GPU。 传统服务器大量采用 48V，因为传统互联网时代机柜功率不高。但 AI 时代，低压系统的问题开始全面暴露。因为： P = VI 同样 1MW 功率，48V 需要超过 20,000A 电流，400V 大约 2,500A，800V 进一步下降到约 1,250A。 电流下降意味着铜缆变细、铜损下降、发热下降、母排缩小、PSU 压力下降、液冷压力下降，建设难度下降，成本更低。 800V 是电动车已验证的高压平台，EV 为什么进入 800V？因为快充、高功率、降低线损和降低热损耗。 今天 AI 数据中心遇到的是同样的问题。于是 SiC、高压 MOSFET、高压 DC/DC、高压 PSU、HVDC、Busbar、固态变压器，这些原本偏新能源车的产业链，开始向 AIDC 外溢。 但 800V可能只是开始，真正的大方向是 HVDC（高压直流化）。 这是为什么传统工业电力公司突然重新被市场估值。像 Vertiv、Eaton、Schneider Electric、ABB、Siemens，开始成为 AI 产业链的重要受益者。 这也是为什么功率半导体正在被市场重估值。 英飞凌就是一个典型的从服务汽车的功率半导体无缝过渡到电力基础设施半导体的公司。 英飞凌可能是目前全球少数真正做到“Grid-to-Core”的功率半导体平台。从电网侧高压、HVDC、PSU、GPU 供电、高频 GaN、Driver、Controller、MCU，到功率模块、MOSFET、SiC，几乎全部覆盖。 这也是它最大的护城河。 更重要的是，英飞凌不是 Fabless，而是 IDM。自己设计、自己制造、自己封装、自己测试。这在功率半导体行业极其重要。因为功率半导体和 CPU/GPU 不同。逻辑芯片拼的是 EUV、FinFET、GAA、晶体管密度。功率半导体真正拼的是热管理、高压稳定性、长寿命可靠性、材料、封装、外延和良率。尤其 AI 数据中心未来是长时间满载、高电流、高热密度、高压。制造本身就是技术。 英飞凌现在真正重要的资产，包括 Villach、Dresden、Kulim。其中最关键的是 300mm power fab 和 200mm SiC。市场低估了一点：300mm 功率半导体其实非常难。因为热应力、良率、高压器件、缺陷控制，都远比普通成熟制程复杂。而 AI 时代，功率器件需求开始进入大规模扩张阶段。先进功率半导体制造能力本身，开始重新变成护城河。 如果只看“最纯”的 AI 高压 power 玩家，则是 Navitas Semiconductor 和 Wolfspeed 这种公司。尤其 Navitas，本质上是 GaN + AI 高效率 power 的纯 Beta。 Wolfspeed 则是另一种逻辑。市 AI 数据中心如果全面进入 SiC PSU、HVDC、高压电力架构，那么它可能迎来第二增长曲线。 另外还有大型工业电力平台。比如 Eaton、Schneider Electric、ABB。因为它们控制的是配电、中压、低压、断路器、电力管理和数据中心 power topology。而这些东西的 switching cost 极高。AI 最终会发现，GPU 可以换代，但电力架构一旦确定，生命周期极长。 总的来说，谁能持续解决 AI 超高功率密度时代的电流、热、效率、配电、可靠性和电网接入，谁就可能在这个赛道上持续领先。因为 AI 的下一轮瓶颈，已经开始从 GPU，转向 Power。而这条产业链，现在还远没有被市场 fully priced in。 免责声明：本人持有文章中提及资产，观点充满偏见，非投资建议，dyor
