The death toll from flash floods that struck central Texas on Friday has now climbed to more than 100 people and an unknown number of others are missing.
Search and rescue teams are wading through mud-piled riverbanks as more rain and thunderstorms threaten the region, but hope was fading of finding any more survivors four days after the catastrophe.
Camp Mystic, a Christian all-girls' summer camp, confirmed at least 27 girls and staff were among the dead. Ten girls and a camp counsellor are still missing.
The White House meanwhile rejected suggestions that budget cuts at the National Weather Service (NWS) could have inhibited the disaster response.
At least 84 of the victims - 56 adults and 28 children - died in Kerr County, where the Guadalupe River was swollen by torrential downpours before daybreak on Friday, the July Fourth public holiday.
Some 22 adults and 10 children have yet to be identified, said the county sheriff's office.
Camp Mystic said in a statement on Monday: "Our hearts are broken alongside our families that are enduring this unimaginable tragedy."
Richard Eastland, 70, the co-owner and director of Camp Mystic, died trying to save the children, the Austin American-Statesman reported.
Local pastor Del Way, who knows the Eastland family, told the BBC: "The whole community will miss him [Mr Eastland]. He died a hero."
In its latest forecast, the NWS has predicted more slow-moving thunderstorms, potentially bringing more flash flooding to the region.
Critics of the Trump administration have sought to link the disaster to thousands of job cuts at the NWS' parent agency, the National Oceanic and Atmospheric Administration.
The NWS office responsible for forecasting in the region had five employees on duty as thunderstorms brewed over Texas on Thursday evening, the usual number for an overnight shift when severe weather is expected.
White House press secretary Karoline Leavitt rejected attempts to blame the president.
"That was an act of God," she told a daily briefing on Monday.
"It's not the administration's fault that the flood hit when it did, but there were early and consistent warnings and, again, the National Weather Service did its job."
She outlined that the NWS office in Austin-San Antonio conducted briefings for local officials on the eve of the flood and sent out a flood watch that afternoon, before issuing numerous flood warnings that night and in the pre-dawn hours of 4 July.
Trump pushed back when asked on Sunday if federal government cuts had hampered the disaster response, initially appearing to shift blame to what he called "the Biden set-up", referring to his Democratic predecessor.
"But I wouldn't blame Biden for it, either," he added. "I would just say this is a 100-year catastrophe."
Texas Senator Ted Cruz, a Republican, told a news conference on Monday that now was not the time for "partisan finger-pointing".
One local campaigner, Nicole Wilson, has a petition calling for flood sirens to be set up in Kerr County - something in place in other counties.
Such a system has been debated in Kerr County for almost a decade, but funds for it have never been allocated.
Texas Lt Gov Dan Patrick acknowledged on Monday that such sirens might have saved lives, and said they should be in place by next summer.
Meanwhile, condolences continued to pour in from around the world.
King Charles II has written to President Trump to express his "profound sadness" about the catastrophic flooding.
The King "offered his deepest sympathy" to those who lost loved ones, the British Embassy in Washington said.
The first malaria treatment suitable for babies and very young children has been approved for use.
It's expected to be rolled out in African countries within weeks.
Until now there have been no approved malaria drugs specifically for babies.
Instead they have been treated with versions formulated for older children which presents a risk of overdose.
In 2023 - the year for which the most recent figures are available - malaria was linked to around 597,000 deaths.
Almost all of the deaths were in Africa, and around three quarters of them were children under five years old.
Malaria treatments for children do exist but until now, there was none specifically for the very youngest babies and small children, who weigh less than 4.5kg or around 10lb.
Instead they have been treated with drugs designed for older children.
But that presents risks, as doses for these older children may not be safe for babies, whose liver functions are still developing and whose bodies process medicines differently.
Experts say this has led to what is described as a "treatment gap".
Now a new medicine, developed by the drug company Novartis, has been approved by the Swiss authorities and is likely to be rolled out in regions and countries with the highest rates of malaria within weeks.
Novartis is planning to introduce it on a largely not-for-profit basis.
The company's chief executive, Vas Narasimhan, says this is an important moment.
"For more than three decades, we have stayed the course in the fight against malaria, working relentlessly to deliver scientific breakthroughs where they are needed most.
"Together with our partners, we are proud to have gone further to develop the first clinically proven malaria treatment for newborns and young babies, ensuring even the smallest and most vulnerable can finally receive the care they deserve."
The drug, known as Coartem Baby or Riamet Baby in some countries, was developed by Novartis in collaboration with the Medicines for Malaria Venture (MMV), a Swiss-based not-for-profit organisation initially backed by the British, Swiss and Dutch Governments, as well as the World Bank and the Rockefeller Foundation.
Eight African nations also took part in the assessment and trials of the drug and they are expected to be among the first to access it.
Martin Fitchet, CEO of MMV, says this is another important step on the road towards ending the huge toll taken by malaria.
"Malaria is one of the world's deadliest diseases, particularly among children. But with the right resources and focus, it can be eliminated.
"The approval of Coartem Baby provides a necessary medicine with an optimised dose to treat an otherwise neglected group of patients and offers a valuable addition to the antimalarial toolbox."
Dr Marvelle Brown, associate professor at the University of Hertfordshire's School of Health, Medicine and Life Sciences, says this should be seen as a major breakthrough in saving the lives of babies and young children.
"The death rate for malarial infections, particularly in sub-Saharan Africa is extremely high - over 76% of deaths occur in children under five years old.
"Increase in death from malaria is further compounded in babies born with sickle cell disease, primarily due to a weak immune system.
"From a public health perspective, Novartis making this not-for-profit can help with reducing inequality in access to healthcare."
除了 iPhone 17 系列之外,苹果下半年最重要的新品,可能是自研的 M5 系列芯片。
据 MacRumors 报道,苹果将在下半年发布一系列新硬件——包括 iPad Pro、iMac、Mac mini、MacBook Pro 以及 vision Pro,而这些产品的共同点在于,都将搭载苹果 M5 系列芯片。
芯片,已然是苹果生态最重要的护城河。

自苹果 M1 芯片发布以来,基本延续了一代大升级,一代小改款的策略,例如 M2 相较 M1 在 GPU 方面提升明显,但 M3 在性能提升方面则幅度不大,而 M4 又是性能跃升的一代——按照这个规律来推测,M5 很有可能是「性能小改款」的典型代表。
▲ M4 芯片. 图片来自:Apple
据爆料称,M5 芯片将延续 M4 的设计,整体性能不像 M3 到 M4 那样大幅度提升,但会更加注重对 AI 需求的优化,并多个方面进行微调,这也符合苹果芯片在 AI 方面的倾向。
M5 将采用第三代台积电 3nm 工艺制造,相比 M4 芯片在能效方面有所提升:
值得一提的是,M5 Pro、M5 Ultra 芯片将采用台积电的 SoIC-MH(2.5D 堆叠)封装工艺,实现 CPU 与 GPU 的分离设计,预计在散热方面会有更好的表现。

关于苹果 M5 系列芯片,一个有意思的细节是——苹果并没有采用台积电最先进的 2nm 制程工艺,而这或许也是为了控制芯片成本。
▲芯片历程 图片来自:台积电
众所周知,芯片是一个研发投入重、回报周期长的行业,每一代 M 系列芯片的研发费用都高达数亿美元,但带来的领先优势却只有短短一两年,这对于销量远不如 iPhone 的 Mac 产品线而言,这是一笔不容忽视的成本。
国际商业战略公司 (IBS) 首席执行官 Handel Jones 曾表示,先进芯片的研发成本在 28nm 之后会水涨船高,设计一块 28nm 制程的芯片,平均成本为 4000 万美元;而 7nm 芯片的成本高达 2.17 亿美元,5nm 为 4.16 亿美元,3nm更是将耗资高达 5.9 亿美元。
▲ 苹果历代 M 系列芯片性能对比.
▲ 设计芯片所需的平均研发成本.
芯片制造成本也不便宜,以 M1 系列芯片为例,M1 芯片的制造成本约在 50 美元左右,M1 Pro 约 100 美元,而芯片面积更大的 M1 Max 造价高达 200 美元,M1 Ultra 因采用堆叠设计,成本高达 500 美元——这也就不难理解,为什么苹果并没有推出 M4 Ultra 芯片,因为实在太贵了!
如此庞大的研发投入,对于苹果来说,这既是竞争力的来源,也是一项沉重的负担。从 5nm 制程起步的 M 系列芯片,每一次芯片制程的提升,都意味着十几亿美元的支出。

为了摊薄高额的芯片研发成本,苹果将 M 系列芯片,引入到了更多的产品线当中——其中最大的现金奶牛,就是 iPad。
早在 2020 年,苹果就推出了搭载 M1 芯片的 iPad Pro,并且持续推动 M 系芯片在 iPad 产品线上的运用,目前,iPad Air 和 iPad Pro 系列已经全线搭载 M 系芯片,价格自然也是水涨船高。
2023 年,苹果发布的空间计算设备 vision Pro 就搭载了一颗 M2 芯片,用于驱动复杂的空间计算场景;2024 年, 苹果在 iPad Pro 上首发了 M4 系列芯片;随后,我们又看到了更多搭载 M4 系列芯片的 Mac 电脑,以及售价近 10 万元,搭载 M3 Ultra 处理器的 Mac Studio,在上面能直接跑满血版的 DeepSeek-R1 大模型——可以预见,苹果这种「全家桶」战略还将会延续下去。
一方面,是为了摊大饼,另一方面,也是为了筑高墙,而留给对手的时间只会越来越少。

我们都知道 AI 在改变我们,但我们都在默默地接受它的驯化。
我们可以先看看,工具与小麦,在历史上是如何改变人的。
1 、从最早的用石头砸坚果,到发现某些锋利的东西,比如石片可以切割,人类开始了更精细化的工具。
EEG 实验显示,切割型石器激活的大脑区远超砸坚果,提示工具精细化←→脑区进化形成正反馈;
化石测量显示,脑容量曲线几乎与石器复杂度同步上扬;
同时,更锋利的工具、更犀利的工具,代表更高的剩余价值=允许一部分人脱离狩猎,诞生艺术家、祭司、治金匠等职业分化。
2 、从野花野草野果,到小麦,稳定的碳水与更容易储存的粮食,从猎人,变成农夫,带来稳定、定居、村庄、城邦等开始形成。
而早期转用小麦的单一饮食,带来平均身高下降,早期农夫更易缺铁、蛀牙,原因是高碳水单一食谱与谷物植酸。
————
而 AI 带来的是什么转变?
1 、工具化的极致,Vibe Writing ,Coding ,Painting ,人均作家、工程师、画家,AI 成为了每个人的“隐形同事、顾问、伴侣”,更多的咨询量与互动,即使 AI 的能力不上升,人类也会像懒蚂蚁一样,探索出更多的用法。
在这个阶段,谁先大量使用,谁先发现机遇。
2 、前一阶段的工具化的极致,只是一切的开始,真实的是自动化的极致,当更多的工具、设计、方案爆发,过去没有人力、没有精力、没有动力去改变的方方面面,都从 AI 助力,向 AI 智能替代,而且从粗糙到精细,迭代的速度随着 AI 的发展变快。
在这个阶段,谁先将 AI 的效能与收益的通道打通,掌握收入的来源,谁先获取大量财富与对业务的新纪元迭代。
3 、最终阶段与形态,目前暂定未知,或者真的是赛博朋克,也有可能真正的人类飞升,所有的过程全看我们在这一路上的选择与坚守。
———
学习与生活方式方面,过去传统的书本教育,会大量向项目制 PBL 、游戏化 GBL 迭代,更多项目化、游戏化的方式,让人从中获取更多真实的学习经验,而非传统的课本教育,毕竟科教兴国,实干兴邦。
而此时,对于人文方面,同时能够兼备的人才,或者能真正从与人类共舞的过程中,发现更多人类的价值、意义、以及必须坚守的东西。
毕竟人类要干的重复性工作,都交给 AI 了,剩下的人类存在的意义就必须由人类自己来完成。

公司最近指定要用 https://vendure.io/ 这个无头电商开源项目改一个 c2c 虚拟电商出来,看了文档觉得这种开发插件的模式要自定义功能很难改,要看的文档一大堆,大家都是怎么上手这种二开的?
对方把尾款给我砍一半,我没同意。
问了一下律所,发个律师函要 2000 元,起诉赢了收取总金额的 20%,发现请律师还是挺贵的。
各位有什么主意给个建议?
不管是 Google 还是 baidu ,搜 whois 全部都是各种域名注册的广告……
也不想每次都登服务器然后敲 whois 指令去查,
于是用了一点时间配合上 claude.ai 搓出来的前端以及手写的后端,做出来了一个能直接在 Cloudflare Worker 上部署的 whois 查询工具。
原理就是先通过 whois.iana.org 去查询域名后缀(比如.com
) 对应的 whois 服务器地址,
然后再去连域名的 whois 查询信息。
想要的刷起来吧(暂时没有具体开始时间)

目前,早几年小高峰购房黄埔黄陂板块, 目前老婆在白云广园客运站(靠近越秀)附近上班,开车通勤 40 分钟(大概 23km ),然后自己地铁到越秀上班大概 1 小时 10 分钟。上班通勤时间感觉有些长了,以前没购房之前租房都是 10 分钟步行以内。
问题主要有两个: 一、有必要为了缩短通勤时间,补差价 100-150 万换购老婆工作附近的房子吗?
二、越秀是不是随便一个中等水平的小学(例如,桂花岗小学),教育质量和生源是否会比黄埔科学小学(算黄埔中等偏上点的小学)好?
另外,如果越秀中等水平小学比黄埔的中等偏上点的小学好,通过越秀租房+赞助费(6-10w)的方式+以租换租是不是更优的解决方案?
希望大家有类似情况的,积极发言,理性讨论

经这几天的情况,权衡以一下改变醒来必须入睡的想法,改为只要心情不波动就是胜利,睡不睡交无所谓,白天绝不赖床,醒了立即起床。运动改为中午。 补剂一直没吃,吃了担心更大的焦虑。现在一切以稳住心态为主。不在详细记录以后只给每天白天的状态给睡眠打分。
睡眠记录 7 月 1 日 睡眠质量 ⭐️⭐️⭐️
早 hit25 分钟左右,中午闭幕养神约 20 分钟。晚商场散步 70 分钟,白天一天精神状态尚可,没有影响工作效率,也没有出现特别困的情况。 11 点 15 开始尝试入睡(耳塞,耳罩),很快入睡,约 1-2 点醒了(大概是没盖被子冻醒了)很快入睡,约 3-4 点(天已经微亮再次醒来)。入睡困难,不知多久入睡(应该超过一个小时,期间尝试冥想,失败)。7 点 50 时被闹钟吵醒,当时睡眠很深所以很难受,8 点 10 分才真正起床。
7 月 2 日 睡眠质量 ⭐️⭐️
因晚起早 hit20 分钟左右,发现这样效率太低,明天尝试去乐刻。 中午基本没有休息,导致下午有些困意,还没到影响工作的程度。白天不如昨天,晚上在乐刻的跑步机散步 50 分钟,11 点 10 分左右入睡,非常困瞬间睡着,同样约 2-3 点醒来,天没亮,很难入睡,期间冥想失败,还有数次情绪宣泄,觉得起床看书时间约 3 点 30 分,看书约 20 分钟,困意来袭入睡,迷迷糊糊的不知多久睡着,在闹钟响起之前醒来,约 7 点 50 起床
7 月 3 日 睡眠质量 ⭐️⭐️
早上洗漱完成就去了乐刻,吃了一根蛋白棒,椭圆机 40 分钟
7 月 4 日 睡眠质量 ⭐️
放弃早上乐刻的计划,甚至放弃早上的 闹钟,早上时间安排太紧半夜更加焦虑,今天后半夜几乎没睡,今天没有运动。晚上玩游戏 high 了 12 点才睡。
7 月 5 日 睡眠质量 ⭐️⭐️
还是半夜醒,7 点就行了一直赖床,10 点半才起床,中午去健身房了。
7 月 6 日 睡眠质量 ⭐️⭐️
半夜醒,入睡困难,还睡过头约 9 点才醒,醒来脑袋昏昏的还不如缺乏睡眠的状态好,天气太热一天几乎都在床上。
7 月 7 日 睡眠质量 ⭐️
半夜醒,一直没睡着,期间情绪波动数次。6 点半醒来。白天巨困,坚持没有午睡,差点在座位上睡着,但是开个会空调太凉又让我冻得不困了,今天没运动。
7 月 8 日 睡眠质量 ⭐️⭐️⭐️
可能是太困了,前半夜睡得很沉根本没做梦,第一次醒来也很亏睡去,第二次醒来约五点,听了一个引导冥想的视频平复心情,约一个小时睡着。可惜醒来都八点半了,睡得太多导致有点昏沉。
最近半年一直在尝试间歇性断食,刚开始总是在心算需要断食的时间,既麻烦又容易算错,就想做个直观好用的工具
