苹果 AI 总结新闻闹乌龙,这比「标题党」更令人担心

万万没想到,苹果 AI 也会有被大骂「标题党」的一天。这对于迟迟没有推出 Apple Intelligence 完全体的苹果可不是一个好消息。

实际情况可能比「标题党」这个不痛不痒的形容词严重得多。如果说标题党只是通过夸张和断章取义的手法来博眼球的话,苹果 AI 的所作所为可以说是「颠倒黑白」。

需要澄清的是,这次「闯祸」的责任完全在于苹果 AI,跟 ChatGPT 的接入没有任何关系。

近日,英国广播公司(BBC)发布了一系列关于路易吉·曼吉奥内(Luigi Mangione)谋杀美国联合健康保险公司首席执行官布莱恩·汤普森(Brian Thompson)的新闻和跟踪报道,提到了其将面临一级谋杀指控等细节。

然而,BBC 提供的一张截图显示,苹果 AI 总结生成的新闻摘要是「路易吉·曼吉奥内开枪自杀了」(Luigi Mangione shoots himself)。这与事件的真实走向大相径庭:据报道,目前他仍被关押在宾夕法尼亚州的监狱中。

太离谱了,错得太离谱了。

针对这一令人啼笑皆非的错误,BBC 已经向苹果正式提出投诉,要求后者要求采取纠正措施,并且防止此类错误再次发生。BBC 发言人表示其「致力于实现最高标准的准确性和公正性,并努力避免故意严重误导我们的读者」。

此外,无国界记者组织(Reporters Without Borders,简称 RSF)也敦促苹果放弃其生成式人工智能功能。该组织表示「虚假标题」事件表明「生成式 AI 服务仍然太不成熟,无法为公众提供可靠的信息」。

无国界记者组织的技术和新闻部门负责人文森特·伯蒂尔(Vincent Berthier)表示 AI 是概率机器,事实不能通过掷骰子来决定。他还指出《欧洲人工智能法案》并未将信息生成类 AI 归为高风险系统,留下了「严重的法律真空」。

实际上,这不是苹果 AI 摘要第一次「新闻造假」了。上个月,美国调查新闻网站「ProPublica」的一位名为肯·施文克(Ken Schwencke)的记者在 Bluesky 上分享了一张截图。

截图中的第一条新闻赫然写着「内塔尼亚胡已经被逮捕」(Netanyahu arrested)。然而,真实的情况是国际刑事法院对以色列总理内塔尼亚胡发出逮捕令。

这篇被苹果 AI 严重歪曲的报道来自《纽约时报》(NYTimes),后者目前并未对此事发表评论。

苹果 Apple Intelligence 的智能生成摘要功能于今年下半年正式推出。苹果的本意,是它能「通过其深度语言理解帮助提炼对你最重要的信息,通知会生成摘要以便你一览重要详细信息」。

看来,苹果所提到的「深度语言理解」似乎水分很大。伦敦城市大学的媒体政策教授佩特罗斯·伊奥菲迪斯(Petros Iosifidis)表示苹果的错误「看起来很尴尬」。

伊奥菲迪斯还表示他「对苹果会推出这样明显半生不熟的产品感到很惊讶」。虽然这项技术在未来具有潜在优势,但是目前「存在传播虚假信息的真正的危险」。

生成式 AI 技术发展到今天,我们似乎很自然地认为用其来总结一篇文章对于 AI 来讲是「小菜一碟」。事实上,大多数 AI 工具在使用时很少会出现「瞎编」的情况,理解有误或者「断章取义」的情况倒是比较常见。

除了苹果之外,谷歌和微软等科技企业也在尝试使用人工智能技术来对新闻进行分类、排序和摘要总结。这类 AI 工具虽然能够增强用户体验,但其在没有人工干预的情况下一旦出错,所引发的「误会」便可能成指数级传播。

虽说 AI 已经能在大多数场景下出色地帮助人们提高工作效率,但其出错的概率绝不为零。于是,我们不得不在「承担错误风险」和「享受 AI 的便利」之间做出几乎唯一的选择。

下一次,面对社交媒体上的一切信息,我们都要「擦亮眼睛」。

3 年 50 次迭代:我编写了一款专为 Mac 打造的休息提醒工具

Kakarottoxxxx: 三年前,我开始开发 macOS 休息提醒工具 Eye Monitor ,目前这款应用已经常驻在 App Store 健康榜的前三位。

Eye Monitor 的设计初衷是因为本人常常面对电脑一工作就是 3 、4 小时不停歇,长时间的用眼和久坐导致我在某个时期视力下降明显以及出现腰酸的现象。

Eye Monitor 工作原理很简单:它通过你在 Mac 上的鼠标移动和键盘使用来自动识别你是否在使用电脑,并在长时间使用后弹出弹窗提醒你休息。所以你不需要手动地设置提醒。

这三年进行不少功能迭代,其中我最喜欢的功能有三个:
1 、数据报表:可以查看历史上使用时长、休息完成率等数据的趋势,并且数据可以通过 iCloud 同步,也可以下载到本地
2 、自定义全屏弹窗的壁纸和提示词:颜值即正义
3 、iOS 提醒:我发现自己常常在 Eye Monitor 提示我休息后离开电脑开始玩手机,可以称之为“假休息”。所以我也写了一个 iOS 版本,用来接收 Mac 的提醒并在手机上也弹出提醒,这样可以让我回头是岸。


清华大学有句口号叫做“为祖国健康工作五十年”,希望大家共勉之。

拍摄 RAW 格式对个人用户的意义到底是什么

看了一下之前拍摄的照片,大量的 RAW 格式存在硬盘上。大部分都是没有修的图——因为拷卡的时候一起拷了。只有少部分被选过,挑出来修了之后导出了修图之后的 JPG/PNG 。没被选中的也没删。这么多年这些照片也几乎没有打开看过。

虽然 Windows 已经添加了主流相机的 RAW 格式读取支持,但是读取依然比 JPEG 慢一截。

Mozambique on edge before ruling on disputed election results

Mozambican police officers arrived in an armoured vehicle as smoke billows from burning tyres and protesters stand in a road

Mozambique is on edge ahead of a ruling expected on Monday to determine the final results of October’s disputed elections, after allegations of rigging triggered weeks of protests in which security forces have killed dozens of people.

The opposition presidential candidate Venâncio Mondlane has threatened “chaos” if the constitutional council confirms the initial election results, which gave the ruling party candidate, Daniel Chapo, 70.7% of the vote and Mondlane 20.3%.

The Podemos party, which is allied with Mondlane, said it should have 138 out of 250 seats in parliament, instead of the 31 that the election commission said it had won.

Mozambique’s Catholic bishops alleged that ballot-stuffing had taken place, while EU election observers noted “irregularities during counting and unjustified alteration of election results”.

Mondlane has repeatedly said he won and has urged his supporters to take to the streets. This has brought the economy to a near standstill, including shutting the border and disrupting trade with South Africa.

Security forces have cracked down in response, killing at least 130 people and injuring hundreds more, according to Human Rights Watch. Local media reported that security forces shot dead two mourners on 14 December at a funeral for a blogger known as Mano Shottas, who had been killed while livestreaming a protest two days earlier.

Recently, some protesters have become violent, with offices of the ruling party, Frelimo, set on fire and a statue of the former defence minister Alberto Chipande, who is credited with firing the first shot in Mozambique’s war of independence, pulled down.

“On Monday the whole country must stop,” Mondlane said on Friday in one of his regular broadcasts, which he has been streaming on Facebook from an undisclosed location abroad, where he claims he fled to avoid being assassinated.

Mondlane called for prayers in the south-east African country on Sunday. “We are giving the opportunity to pray for the judges of the constitutional council, to pray for [its chair] Dr Lúcia Ribeiro, so that on Monday, from her, justice comes out, the electoral truth does not come out as a lie,” he said.

Mozambique’s outgoing president, Filipe Nyusi, rebutted Mondlane’s claim that he was planning to cling to power, saying in a Thursday evening broadcast that he would leave office in January as planned.

He also implicitly criticised Mondlane, saying: “It worries us that the process of choosing our leaders was transformed into a pretext to induce and exacerbate social tensions and violent acts.”

Zenaida Machado, a researcher at Human Rights Watch, said the ruling administration had “decided to brand the entire protest movement as violent to justify their own use of excessive force”.

“The fact that some people within a protest have become violent does not label the entire protests violent,” she said.

While most analysts believe there was some level of rigging, some said it was unclear whether Mondlane had won.

“A 70% majority for Frelimo was a massive surprise to everybody,” said Alex Vines, who was part of a group of election observers from the Commonwealth. “But neither … can [you] say that Venâncio Mondlane won. We just don’t know.

“The [opposition party] Renamo vote collapsed in Renamo heartlands,” said Vines, the head of the Africa programme at the thinktank Chatham House. “Frelimo benefited from that. It was in the urban areas that Podemos and particularly Venâncio prospered, which is not enough, necessarily, to get a majority.”

Four of the constitutional council’s seven judges were appointed by Frelimo parliamentarians, while the chair was appointed by Nyusi.

Adriano Nuvunga, the director of the Centre for Democracy and Human Rights, a Mozambican non-profit organisation, said: “Everything will depend on what they say at the announcement – whether they will confirm the current results with minor changes or whether there will be a change, which is unrealistic. We are bracing for impact.”

客座评论:从线性发展到通货紧缩的怪圈

张俊华

学者的最新预估称,中国有大约9亿人月收入低于3000元

(德国之声中文网)北大的林毅夫是中国线性思维的代表。记得在2015年他就提出我们将在明年即2025年进入“高收入阶段”阶段。按照他的理论,中国在1978—1998年时期是第一阶段是低收入阶段。在这一时间段,中国人均国民总收入从190美元增长到820美元。1999—2009年是中国发展的第二阶段,即下中等收入阶段。2010—2023年则是中国发展的第三阶段,即上中等收入阶段。而从2025年起,中国便进入了第四阶段,即高收入阶段。

最新估测

现在回过头来看,显然,他的乐观预测并没有成为现实。相反,习近平残酷的清零政策以及后来蹩脚的经济政策,导致了中国经济明显的紧缩。尽管在2017,官方声称中国的中等收入族群已超过4亿,而习近平政府又在2020年宣告中国成功地实现了全面脱贫。但《经济观察报》12月7日一个报道,告诉了我们一个残酷的事实:据浙江大学共享与发展研究院院长李实研究并估算,截至目前,未达到中等收入标准的人群数量约占全国总人口的65%,即低收入人群约有9亿人。李实教授的低收入的标准是,月收入低于3000元。

李实教授指出,这9亿人群的收入也存在较大差距,一部分群体的收入接近中等收入水平,而另外一部分群体则处于相对贫困状态。但不管如何,他们的实际生活水准并不令人羡慕。笔者以为,如果把中国目前的“实际可支配的收入低于3000元”的人一同计算,即那些表面上其收入似乎高于3000元,但由于每个月支付房贷和车贷等,最终到手的依然低于3000元的人群算进去,总数可能还多一些呢。

李实的估算,跟中国前总理李克强2020年曾在总理记者会上的说法似乎类似。当时李克强断定,中国有6亿人的每月收入仅为1000元。而中国国家统计局此后回应说,该数据反映了中国的基本国情。如果这样的话,再看一下疫情后的经济下行,各地不少企业不是在倒闭、裁人,就是在减薪。连政府部分和事业单位、国企也不例外。

房企接连爆雷:中国房地产商碧桂园2024年2月28日表示,27日遭债权人提出了清盘呈请。消息一出,碧桂园28日在香港股价下跌约12%。在中国政府欲重建各界对房地产业的信心之际,此事也对经济前景蒙上阴影。此前碧桂园是为数不多的没有出现资金问题的中国大型开发商之一,但2023年上半年亏损达到了67亿美元。9月中,碧桂园获得债权人的批准,将六只境内债券的偿还期限延长三年。
恒大资不抵债:中国房产巨头恒大集团才刚于今年1月底遭香港高等法院裁定资不抵债,勒令清盘。碧桂园债务估计约1.36万亿人民币(约1900亿美元),接近其1.43万亿人民币的资产;恒大集团负债则达到3000亿美元。恒大2023年9月22日提交给证券监管机构的公告中称,由于房地产销售不如预期,该公司认为有必要重新审视350亿美元的债务重组的方案。9月底,恒大证实其创始人许家印"因涉嫌违法犯罪,已被依法采取强制措施"。2021年恒大陷入资不抵债,导致了一系列开发商违约,引发了中国的房地产泡沫崩解。
金融信托巨头陷入财务危机:2023年8月,有报道称中国最大私人信托公司中融信托出现财务危机,无法完成信托产品的兑付,影响范围可能达到人民币3500亿元。其母公司中植集团也承认有流动性困难,计划债务重组。8月16日,约二十名抗议者在北京中融信托大楼前抗议要求还钱,他们购买了高收益的金融产品,却无法得到兑付。信托业历来是房地产商重要的资金来源,房地产业的爆雷也使信托业陷入危机。
放松限购刺激房市效果不彰:中国央行2023年8月宣布降低首次购房者现有抵押贷款利率,以及部分城市的购房首付款比例。从8月末到9月初,广州、深圳、北京、上海相继官宣实施"认房不认贷"政策,名下无房人群的购房门槛比之前降低,不少购房人将由二套房资格变为首套房资格,首付比例大幅下调。此后有报导指北京的房产交易出现小幅反弹。但更多的专家指出,这些措施可能会使房地产交易中产生短期反弹,但不足以稳定房地产市场。”
空置房屋“14亿人住不完”:据中新社发布的一段视频,中国国家统计局原副局长、全国人大财经委副主任的贺铿9月23日在2023中国实体经济发展大会上称,“现在房地产供应过剩,空置的房屋究竟有多少,各个专家估出来的数字相差很大,但是14亿人可能住不完。”他认为“房地产企业必须转型,早转型早主动”。
数百万套房屋未售出:资产管理集团思睿投资(Grow Investment)首席经济学家洪灏表示,调整中国的房地产行业可能需要多年甚至长达十年的时间。“原因是,我们为中国人建造了太多的住房。”中国国家统计局的数据显示,截至2023年8月底,全国未售出房屋的总建筑面积为6.48亿平方米。根据路透社的计算,以平均房屋面积90平方米来算,中国未售出房屋的总建筑面积当于720万套房屋。这还不包括因现金流问题已售出但尚未竣工的大量住宅项目。

官方数据的水分

当然,为了迎合习近平的在经济下行时期只能唱赞歌的原则,官方不少数据依然在渲染“形势一片大好”。如中国社会保障学会日前还宣布,如果按照2023年个税清缴数据报告推算,每月收入人民币3500元以下的超低收入人口逾6亿。而中国官方的国内生产总值GDP也是如此报道的。

而最近冒出了两个经济学家,则对此进行了批驳,以至于他们被官方消音。一位是国投证券首席经济学家高善文,他根据经济增长、就业、消费和投资数据无法吻合的情况推断,2021年至2023年期间,中国的国内生产总值(GDP)“增速每一年高估了3个百分点,累计高估了10个百分点”。高善文认为当前的失业严峻程度和官方公布的经济增速有很大反差,并推算新增就业人口比正常状态下少了4700万。

另一位是东北证券经济学家付鹏,他在一次会议演讲中说,消费疲软源于房地产价格下跌,导致一些中产阶级房主出现负资产;中产阶级又因裁员、降薪等因素产生恐慌,开始大幅压缩支出。这种消费能力的下降不是短期现象,而是一个结构性的转变。付鹏对目前政府实现这个结构转变的能力是持有怀疑态度的,他说,“由于问题深重,政府通过加杠杆刺激经济的措施,已难扭转中产阶级迅速萎缩的趋势”。付鹏的分析不是没有根据,因为中国的房地产包含了中国70%的家庭财富,持续的危机会削弱消费者和企业的信心。

事实确实是这样:中国今年经济表现不佳,官方陆续出台纾困政策,但迄今未开花结果。今年房地产危机持续恶化,地方政府债务高企,消费疲软不振,出口乏善可期,企业与资金继续外流。中央确实也推出了各种措施刺激经济,但官方的刺激措施已无法像2008年那样奏效。

过去传统三大经济火车头,基础建设投资、房地产和出口,近年都面临停滞。房地产业占GDP高达16%,加计基建投资更占到约24%,但房地产已无火车头的拉动效用,无法成为经济增长主要动能,甚至成为拖累因素。而基建投资由于地方政府债务繁重,已无法像以往那样大手大脚地操作了。

基建放缓:江苏南京,距离上海约300公里的省会,成排高铁列车在南站停靠。中国计划2024年新开通14条高铁,全长1700公里。多年来,中国一直力推基础设施建设。但如今,大规模基建放缓。

内卷的汽车:南京一处报废汽车停放场地。作为全球最大汽车销售市场,中国汽车行业内卷十分严重。与此同时,报废汽车对环境的污染问题也有待解决。

习近平的尝试和新的许诺

至于出口实际上正是习近平对提升中国经济希望的寄托:因为习近平自2020年就开始努力,希望通过发展高科技的工业,并出口它们的产品(如新三件:即电动车、车用电池、太阳能板), 来实现经济结构的转型,即用高科技产品来替换原来的经济动力,即房地产和国内的消费,但显然,由于他不精明的经济外交(如倾销),在国外阻力重重。

而随着中国经济的明显下滑,中国的年轻人和中年人的生活负担日益加重,以致于到了有人“吃了上顿顾不了下顿”的地步。中国目前法拍房剧增、无家可归的人增加,以及无差别害人的事件愈演愈烈,无不说明了这个“重返集体贫困”的问题。面对上述问题,中央层面不能说一无所知毫无感觉,在本月的几个重要会议上,中央层面已经释出了“异常紧迫”的信号。习近平自己在中央经济工作会议上发出如下的许诺:

即“推动中低收入群体增收减负,适当提高退休人员基本养老金,提高城乡居民基础养老金,提高城乡居民医保财政补助标准。加大保障和改善民生力度,增强人民群众获得感幸福感安全感”。 但迄今为止,习近平更关心的实际上是他的所谓“新生产力”,而非百姓的生活质量。中央宁愿为制造业多花钱,也不愿意为百姓提高收入。

中国能走出通货紧缩的怪圈吗?

本月11至12日在北京举行中央经济工作会议,也作出如下决定,即2025年要提高财政赤字率、增发超长期特别国债、适时降准降息以保持流动性充裕,以及实施“适度宽松的货币政策”等宣示,未公布具体的政策措施。换言之,中国2025年的财经政策将因此从保守走向宽松扩张。这意味着,决策者可能设定高达4%的高于往常的赤字目标 (以往的上限是3%),人民银行(中国央行)印钞票去买国债, 从而为增加中央政府借款以提振经济奠定基础。另外,2025年政策利率极有可能下调40个基点,如果是这样,这将是自2016年以来的最大降幅。但上述的各项宣示重点主要仍偏向“增加政府的开支”,却缺乏如何“增加民众的开支”以促进消费。 最终,习近平上面一大串许诺即有可能成为一张空头支票。

现在看来,中国至少在今后一两年内很难摆脱通货紧缩的怪圈。所谓通货紧缩就是由于有效需求的严重不足导致商品与服务的价格下降,而人们的购买意愿的低下则又促使前者价格再进入一个新的一轮的下跌(主要工业产品,日常用的食品例外),导致经济进一步衰退。中国的通货紧缩现在正在进入一种恶性循环,这并非是通过印钞票能解决的。

Last Week on My Mac: School of Athens or Blinded Samson?

I wonder whether we’ll look back at 2024 as the year that Apple Intelligence came to our Macs and devices?

While there are plenty of nay-sayers, and those who still accuse Apple of falling behind, there can be few who aren’t aware of what’s available to those who have bought a recent Mac or one of the higher-end iPhones or iPads. Since Apple’s attempt to hijack the established abbreviation AI at WWDC last summer, we have heard little else. There can have been few minor updates that were sold as heavily as the autumn’s x.1 and x.2 releases for their lavishly preannounced new features.

We’ve been beta-testing some of those features for as long as we’re normally allowed for a whole major release of macOS. Over that period, the number of users who have switched to English (US) as their primary language must have been substantial. It’s the first time I have kept one of my Macs running beta-releases long after the annual macOS upgrade, and I only reverted when 15.2 was released with AI support for English (UK).

Although these AI features have their uses, and for many should prove quietly revolutionary, I’m not convinced that they transform our Macs or devices into anything even remotely intelligent, and a far cry from the great thinkers in Raphael’s masterpiece The School of Athens. The central figures here are Plato (left), who carries in his left hand a book titled TIMEO (I am afraid), and Aristotle (right), whose book bears the word ETICA (ethics). Seen further to the left in profile is Socrates, and below him is Pythagoras writing in a book while a boy holds in front of him a small blackboard showing the theory of harmony.

Contrast that hullabaloo about AI with Apple’s complete silence on security, specifically the changes brought in its front-line malware detection feature XProtect in macOS Sequoia, since its release on 16 September. Prior to that, XProtect’s data bundle, including its Yara file of detection signatures for malicious software, had been maintained by the general macOS update service through softwareupdated. The diagram below outlines this long-established process.

xprotectupd1

When Sequoia 15.0 was released, that changed to what has turned out to be an intermediate invoking both the old mechanism and the new.

xprotectupd2

For the first couple of weeks of that, XProtect updates were chaotic:

  • 13 Sep (approx) Software Update Service stopped providing regular XProtect updates
  • 13 Sep (approx) XProtect version 5273 available from Software Update Service for Sequoia only
  • 16 Sep macOS 15.0 released, with version 5273 available from Software Update Service for Sequoia only; upgraded Macs updated to 5273 by copying from secondary to primary locations; 5273 not provided from iCloud, where 5272 remained the current version
  • 18 Sep Software Update Service resumed delivery of 5272 to Sonoma and earlier
  • 18 Sep Software Update Service started delivery of 5274 to Sonoma and earlier; 5273 no longer available for Sequoia, with 5272 still available from iCloud
  • 24 Sep Software Update Service delivered 5275 for Sequoia; no change to Sonoma and earlier, and 5272 still available from iCloud.

Then, just as we were getting the hang of it, Sequoia 15.2 excised the old mechanism, as we discovered last week when Apple released the first update to XProtect since 15.2.

xprotectupd3

Throughout all of this, Apple has remained completely silent. What’s even more surprising is that in the last few days, Apple has updated its definitive guide to security for Macs and all its devices. Although not all localised English translations have yet been synced with its US or Canadian English versions, the account of XProtect now has a published date of 19 December 2024, but doesn’t mention September’s changes.

There are those who insist that none of this is our concern, we should just let Apple do whatever it deems appropriate, and we shouldn’t even know what version of XProtect’s data is installed, as macOS takes care of all that for us. However, the security of my Mac is very much my business. If I were to unwittingly install malware that stole sensitive information, those are my banking details at risk, not Apple’s. Should I suffer financial loss as a result, would Apple provide unlimited compensation?

Hardly. Read sections 8 and 9 of Apple’s licence for macOS Sequoia, and the onus is clearly placed on the user. Just to emphasise this, further down that licence, in the Apple Pay & Wallet Terms and Conditions, is the express statement: “You are solely responsible for maintaining the security of your Mac Computer, Supported Devices, your Apple Account, your Touch ID information, the passcode(s) to your device(s), and any other authentication credentials used in connection with the Services (collectively, your “Credentials”).” The next time someone says that you should leave the security of your Mac to Apple, remind them of that.

Apple also encourages us to take an active part in our Mac’s security protection, and provides us with tools for doing so. The description given in man xprotect is a good example: “xprotect is used to interact with XProtect. It is useful for administrators or users who want to manually invoke XProtect functionality.”

Information about XProtect updates is exposed in the GUI, in System Information, where each update including those delivered by both old and new mechanisms is listed, together with its version number. That in itself is puzzling, as recent entries incomprehensibly duplicate older XProtectPlistConfigData entries with newer XProtectCloudKitUpdates.

So if AI doesn’t bring us the School of Athens, what has macOS Sequoia achieved so far? For this second image I turn to Lovis Corinth’s first major painting after his near-fatal stroke just before Christmas in 1911, an autobiographical portrait expressing his frustrations, in The Blinded Samson from 1912.

Please don’t breathe a word of this over on Apple Support Communities, though, where it seems your Mac’s security should be like mediaeval religion, a matter of blind faith and the suppression of knowledge. It’s high time for a Renaissance, much more Enlightenment, and a modicum of Intelligence.

'I heard rumbling and shattering glass': Eyewitness describes Christmas market attack

Reuters Armed officer stands in front of building with Christmas decorations projected onto it and an ambulance to the side in MagdeburgReuters

A woman who was with her boyfriend at the Christmas market in Magdeburg has told local media she had her boyfriend in her arms when the car used in the attack came speeding towards them.

"He was hit and pulled away from my side. It was terrible," 32-year-old Nadine told the Bild newspaper.

Footage published on German media showed a black car striking a crowd of people at high speed and continuing to drive forward for hundreds of metres.

Nadine's boyfriend is said to have sustained injuries to his leg and head.

Another eyewitness, Gianni Warzecha, told the BBC he was listening to Christmas music at the market with his girlfriend's family when "suddenly there was a rumbling and the sound of shattered glass".

"People began to panic," he said. "I saw the car and people on the floor, people bleeding. There were also kids.

"I was concentrating on getting first aid to people. It took a few minutes for the first paramedics to arrive but it wasn't enough because there were already 200 people hurt.

"Most of the first aid was done by people there."

Lars Frohmüller, a reporter for the public broadcaster MDR who arrived at the Christmas market in Magdeburg shortly after the attack, told the BBC about what he saw.

"Everywhere were ambulances, there were police, there were a lot of fire workers.

"This was a real chaotic situation. We saw blood on the floor, we saw people sitting beside each other and having golden and silver foils around them. And we saw many doctors trying to keep people warm and help them with their injuries.

"It's a big shock. It's a big shock for every people here in Magdeburg and for every person in Saxony-Anhalt."

Tobias Rausch, who was at the Christmas market and serves as general secretary of Germany's far-right AfD party in Saxony-Anhalt, told Reuters it was scary.

Rausch said he had not reached the market when "all of a sudden, we heard a muffled noise, an engine roaring".

"People were screaming. It all happened in a fraction of a second."

Once away from danger, Rausch said he was able to film the moment police detained the suspect.

Local officials told a news conference that fellow citizens had given vital first aid to those hurt in the moments before emergency services arrived on the scene.

One Magdeburg resident, Heike Janke, was at the Christmas market on Friday and left at around 18:00 local time (17:00 GMT), roughly an hour before the attack took place.

"We could have been hit," Ms Janke told Reuters, as she lit a candle for those involved in the tragedy. She said she felt appalled by what happened, "somehow you just can't believe it".

She was joined by many other locals who brought flowers and candles to a church near where the attack happened.

Corinna Pagels, a local and employee with a counselling organisation, said she was at the market herself early on Friday. She said the healing for the community starts now.

"Of course, it gets to you and we also need to process things and thankfully we have a good network and are also there to provide aftercare for rescue workers and firefighters and support them in the aftermath. So the real work starts now."

要充电就买电车,混动是卖给燃油车主的。

qiumaoyuan: 混合动力最开始出现的目的,就是为了省油。根本上是利用了电机与内燃机正好在各自高效工作的区间可以互补的特点,来达到让内燃机要么不工作,要么就只工作在最高效的区间的目的。

最一开始的混动只有油混(不能充电),后来车企在国内的政策下搞出了应付政策的插混。然后插混莫名其妙的似乎更受欢迎起来了,是因为多数人觉得混动的定义是“即可以用电又可以烧油”。其实关于这些问题,10 年前 38 号早就科普过: https://www.bilibili.com/video/BV1EJ411Q7kD

电比油便宜,插混流行起来就会导致一个结果:很多人买了插混之后,图便宜老是充电,这样用的时间久了发现自己不知道加油的意义。再后来,就如很多人发现的那样:既然我整天充电为什么不直接买电车?

对插电混动来说,电池本来就相对纯电车小,续航也短,如果整天不加油,只用电,充电循环次数比纯电增长得快得多,寿命也更容易损耗。而如果正常当作燃油车来用,电池管理系统会自动让电池始终处于浅充浅放的状态,该充电了会自动启动内燃机,做到电池与车辆同寿命。

混合动力本来就是一种高配燃油车,省油的同时,能带来更好的驾驶感受,更低的噪音,更直接的动力。如果这样看待混动,很多关于混动的莫名其妙的疑问自然迎刃而解。

总结一下 3 个观点:

1. 混动是高配燃油车,更省油、更舒适。
2. 插电混动是应付政策(要上绿牌必须能够纯电行驶 xx 公里)的产物。
3. 图电费便宜,直接买电车。

Apple 全家桶用户/HomeKit 用户慎用小米系的路由器

MacsedProtoss:

症状描述

网络拓补大概为 光猫(桥接)- 软路由原版 OpenWrt 拨号/DHCP - Mac Mini Surge 旁路由 - 小米路由器 AP 模式有线 mesh

小米路由器是一台 AX9000 和一台小米万兆路由器 两台都是旗舰机

使用 sunshine-moonlight 串流 串流 host 是 windows 13900K+4090 没有性能瓶颈

当接收方是非 Apple 设备时 例如 steam deck oled ,音画同步 调试信息显示 latency 5ms jitter 1ms

当接收方是 Apple 设备 无论是 iPad Pro 还是 MacBook Pro 还是 Apple TV 都会都会遇到声音断断续续 操作不流畅 调试信息显示 latency 乱跳 几十到上百 ms jitter 也随之变化 幅度也是几十到上百 ms

排查过程

由于只有 Apple 设备有问题 所以就在 GitHub issue 中搜寻 结果发现了 awdl 相关的 issue https://github.com/moonlight-stream/moonlight-qt/issues/159#issuecomment-568654813

于是将 AP 改为 awdl 的频段 149 ,iPad Pro 上问题消失 我以为是解决了

结果没过几天 问题突然又复现了 遇事不决先重启设备试试 发现问题依旧 于是开始进一步的 debug

首先我发现 awdl 问题苹果其实已经修了 在 macOS13.1 开始就没有问题了 https://systemstatus.ucla.edu/status?id=status_record&service=a8226ec01b1651509ca4a602b24bcb20

其次之前我遗漏了一个点 Apple TV 是有线连接的 为啥也一样出问题呢? 肯定不是 Wi-Fi only 的 awdl 问题导致的

意外收获

所有这些设备无论无线还是有线都是连接的小米 AP 所以第一反应是尝试下重置 AP 重置的时候没注意从分开三频变成了三频合一 然后突然发现所有无线设备网络都巨卡无比 难道是 AP 坏了?当然不是...开启三频合一之后又恢复了

那么开启合一会导致哪些设备也用同一个 ssid 了呢?那就是智能家居 进一步说 是 HomeKit 设备 突然联想到这一块应该是用的 mdns ,但是小米这个 ap 都是旗舰级的咋还有这种问题呢

思来想去还是打算换个 AP 测试一下 于是买了个美版的 Asus ET12 ( AXE11000 )

单个 ET12 确实解决了问题 哪怕没设置为 awdl 频段。但是当我接入一台小米 ap 单独为 HomeKit 设备提供 2.4G 网络时 问题又复现了 也就是说 Apple 设备走 mdns - ET12 - 小米 AP - HomeKit 这个链路就会有问题,去除掉小米 AP 之后就没有问题了

经过两周测试后确认没有问题 于是再入手一只 ET12 组有线 mesh 现在已经平稳运行 2 个月了 问题解决

未解之谜

小米的路由器到底干了啥对于 mdns 的性能如此之差 建议 Apple 用户 尤其是 HomeKit 用户不要考虑购买小米的路由器

镜头从森林深处开始,一片静谧的河流在画面中央缓缓流动,阳光透过茂密的树冠洒在水面上,形成一片金色的光斑。河流周围的景色绿意盎然,偶尔可以听到昆虫和鸟类的鸣叫声。镜头慢慢移动到河中心,突然,一阵激烈的水花打破了平静。画面聚焦到一条巨大的蟒蛇正紧紧缠绕着一只体型庞大的鳄鱼。蟒蛇的鳞片在阳光下闪烁着微弱的光泽,显得坚韧而狡猾;鳄鱼则疯狂扭动着它的身躯,尾巴猛烈拍击着水面,溅起高高的浪花。

鳄鱼张开它那布满利齿的嘴巴发出低沉的咆哮,试图咬住蟒蛇的身体,但蟒蛇灵活地躲开,同时加大了缠绕的力度。镜头拉近,可以清楚地看到鳄鱼的爪子划过水面,激起一道道细碎的水纹,而蟒蛇的每一次动作都带动周围的水流,形成一股暗涌。

就在这场生死搏斗愈发激烈时,一头小鹿突然从左侧树林中冲出,双眼睁得大大的,显然意识到危险正在眼前。它毫不犹豫地迈开修长的四肢,朝着河流疾速奔跑而来。画面随着小鹿的动作移动,清楚地捕捉到它踏入河水时溅起的轻微水花。小鹿以优雅而快速的动作跃入空中,在阳光的照耀下,它的身体几乎像剪影般完美。

当小鹿跳跃的轨迹与正在搏斗的蟒蛇和鳄鱼交错时,鳄鱼的头短暂地转向小鹿,试图评估这突如其来的生物。但就在这瞬间,小鹿已经稳稳地落在河对岸,甩了甩被打湿的蹄子,迅速消失在树林深处。鳄鱼似乎意识到无法追上,重新将注意力放回与蟒蛇的争斗上,水面再次被拍打得水花四溅。

镜头缓缓拉远,远处的小鹿身影模糊地消失在翠绿的森林中,而河流的战斗仍在持续,水花和声音渐渐变小,最终画面切为一片宁静的森林场景。

bt 下载和 UPnP 端口映射问题

为什么用 Discuz 搭建的论坛邮箱服务失效率这么高

bhoppi:

由于深受垃圾邮件骚扰,最近把用了 20 多年的主力电邮地址换掉了,打算把过去所有注册过的 300 多个网站都改一遍。整个改下来发现,大部分网站的修改都很顺利(已关停和被封禁的不算),但有一小部分网站没有改成功,主要是两大类:

  1. 网站不允许修改邮箱;
  2. 网站修改邮箱的功能不工作,主要收不到验证邮件、换绑时各种报错等。

总结下来,出现这些情况的网站绝大多数都是中文网站,这一定程度上体现出了中国互联网发展的特殊性(很多都是以手机号为主、邮箱为辅,甚至一些网站只为老用户保留邮箱但是只读,新用户直接没了这个字段)。最有意思的是,有些网站的国内和国外版都有区别,比如,联想的国际版可以改邮箱,而 CN 版不可以。

以上是背景。我要说的重点是第 2 种情况,网站修改邮箱的功能不工作,除了虎扑、当当等个别网站外,其余大部分都是 Discuz 搭建的论坛。我注册过的 Discuz 论坛有 20 个左右,改邮箱时发现大部分都收不到验证邮件,导致无法修改邮箱。而用基于 phpBB 、Discourse 、Flarum 等框架搭建的论坛基本没有这个问题。

不知道这里面有没有深层次的技术原因,还是纯属巧合,有没有搭建过 Discuz 论坛的坛友来说一说,你们的论坛有没有遇到过这个问题,原因是什么?

各位 V 友帮我分析一下,买新车还是二手车

ZhaoS:

我的个人情况

32 岁已婚 房贷 4200/月,北漂房租 2000/月。

我工资 1.2W ,老婆在家接活,每月 5000 ~ 7000 。

2025 年打算要小孩,可能回老家,可省掉房租

我的到手工资可能降至 8000 ~ 10000 。老婆怀孕前收入波动不大

10W 固定存款不动,可拿出 5w 左右买车。

方案一、

  1. 25 年 年中,买一辆 18 ~ 21 年的二手车(有家人懂二手车)

  2. 25 年~ 28 年,开 3 ~ 4 年 卖掉

  3. 27 ~ 28 年 买新款新能源

    1. 优势 新车更智能、自动驾驶、可能更便宜
    2. 先买二手车,近几年生孩子之类的压力大,二手车更划算
    3. 劣势 旧车 obd 年检、维修。可能不好出手、卖不上价

🌟二手车:

轩逸、卡罗拉等日系,皮实耐用。 Polo 、飞度等两厢车 预算 2 ~ 4 万。车况较好,出问题的几率也小

方案二、

  1. 直接新车 比亚迪海豹 06dmi
    1. 可以开 5 ~ 10 年不换车
    2. 车大、好看、省油,老婆喜欢
    3. 10.68W 次低配,还是要上 12.68W 的 acc 版?年纪大了,精力不足,开长途有 acc 会轻松很多。
    4. 省心
    5. 经济压力大,房贷、车贷、小孩

Archbishop of York 'regrets' that abuse scandal priest had role renewed twice

The Archbishop of York, Stephen Cottrell, was the Bishop of Essex when David Tudor was twice reappointed to a senior position

A Church of England priest at the centre of a sexual abuse case was twice reappointed to a senior role during the Archbishop of York's time as Bishop of Chelmsford, the BBC can reveal.

A BBC investigation previously revealed how David Tudor remained in post nine years after Stephen Cottrell was first told of concerns about him.

New information shows Tudor's contract as area dean in Essex was renewed in 2013 and 2018, at which times Mr Cottrell knew he had paid compensation to a woman who says she was abused by him as a child.

The Archbishop of York said he regrets his handling of the case, with a spokesperson saying "he acknowledges this could have been handled differently".

They added that "all the risks around David Tudor were regularly reviewed" and that was the "main focus".

Rachel Ford, who told the investigation she was groomed by Tudor as a child, said the renewal of his contract as area dean was "an insult to all of his victims".

Ms Ford added that if responsibility for that lay with Mr Cottrell, it strengthened her feeling that he should resign.

The pressure on Mr Cottrell comes at a time of turmoil in the Church of England following a damning report into how it covered up prolific abuse by the barrister John Smyth.

The report led to the resignation of the Church's most senior figure, Archbishop of Canterbury Justin Welby. Mr Cottrell will take over his role temporarily for a few months in the New Year.

The BBC investigation showed Mr Cottrell was briefed in his first week as Bishop of Chelmsford about serious safeguarding issues surrounding Tudor.

These included that Tudor was convicted of indecently assaulting three underage girls and was jailed for six months in 1988, although the conviction was quashed on technical grounds. Mr Cottrell would also have known Tudor served a five-year ban from ministry.

By 2012, Mr Cottrell also knew Tudor had paid a £10,000 settlement to a woman who says she was sexually abused by him from the age of 11. In 2018, the Church of England issued an apology and a six-figure pay-out to another alleged victim.

Yet the priest was suspended only in 2019 when a police investigation was launched after another woman came forward alleging Tudor had abused her in the 1980s.

When first responding to the BBC's investigation, the Archbishop of York said he was "deeply sorry that we were not able to take action earlier", insisting he had acted at the first opportunity that was legally available to him.

Mr Cottrell also said he had been faced with a "horrible and intolerable" situation and that it was "awful to live with and to manage".

When Mr Cottrell became bishop in 2010, Tudor was into the second year of a five-year term as an area dean, a role overseeing 12 parishes in Essex.

His appointment to that post, under a different bishop, happened despite him working under a safeguarding agreement that barred him from being alone with children and entering schools.

The title was renewed twice under Mr Cottrell - in 2013 and 2018 - and he lost the title only when the term of office expired in 2020. It was not taken from him.

A spokesperson for the Archbishop said he "accepts responsibility for David Tudor remaining as Area Dean".

"No-one advised him that David Tudor should not continue as an Area Dean," said the Archbishop's office.

Another of Tudor's victims, who does not want to be identified, said she was "shocked and disappointed" to hear his tenure as area dean was twice renewed during Mr Cottrell's time as Bishop of Chelmsford.

"These are not the actions of a bishop dealing with a situation that was intolerable to him, in fact, quite the opposite. I call on him to do the honourable thing for the sake of the Church and resign," she says.

In 2015, under Mr Cottrell, Tudor was also made honorary canon of Chelmsford Cathedral.

The Archbishop's office insisted it happened because of a change in Church policy during Mr Cottrell's time as Bishop of Chelmsford, meaning area deans were automatically made honorary canons.

It was "not a promotion and not a personal reward".

However, a social media post from Tudor's Canvey Island parish in July 2015 suggests it was seen there as a reward.

Tudor's "hard work, determination and commitment to this place have been recognised by the diocese and this new position in the Church is very well-deserved," it said.

The BBC has also seen evidence - in leaked minutes from internal Church meetings in 2018 and 2019 - that Tudor's titles of area dean and honorary canon were discussed and there had been a suggestion Mr Cottrell could immediately have taken them away.

In October 2018, a meeting at Church House - the London headquarters of the Church of England - heard that Chelmsford diocese took the view that if Tudor "can be a parish priest, he can undertake the other roles".

A bishop from another diocese said "the Bishop of Chelmsford could remove DT's [David Tudor's] Canon and Area Dean titles straight away".

But in a follow-up discussion in November 2018, Chelmsford diocese advised it would not be appropriate because of "the difficulty of removing those titles without explaining why."

We asked Mr Cottrell's office why he had not followed the suggestion to remove Tudor's titles. We were told "it would not be appropriate to comment on any notes or decisions from a core group process which are confidential".

The investigation also highlighted the significant role played by former Archbishop of Canterbury George Carey in the case.

We revealed Lord Carey had agreed to Tudor's return to priesthood after being suspended in 1989, and had also agreed to have Tudor's name removed from the list of clergy that had faced disciplinary action. He had also advocated for the priest.

After the BBC put this information to the former Archbishop of Canterbury, he wrote to give up his "permission to officiate", ending more than 65 years of ministry in the Church of England. Lord Carey made the announcement on Tuesday.

In October 2024, Tudor admitted sexual misconduct and was sacked by the Church. At no point has he responded to the BBC's attempts to speak with him.

US warplane shot down in Red Sea 'friendly fire' incident

The US military says it has carried out a series of air strikes on the Yemeni capital Sanaa targeting a missile storage site and command facilities operated by Iran-backed Houthi militants.

US Central Command added it also hit multiple Houthi drones and an anti-ship cruise missile over the Red Sea.

It comes hours after the Houthis fired a ballistic missile at Israel which injured more than a dozen people in a Tel Aviv park.

The Houthis, an Iran-backed rebel group that controls north-western Yemen, began attacking Israel and international shipping shortly after the start of the Gaza war in October 2023, saying they were acting in solidarity with Palestinians.

In a statement, the US military's Central Command said the strikes aimed to "disrupt and degrade Houthi operations, such as attacks against US Navy warships and merchant vessels in the Southern Red Sea, Bab al-Mandeb, and Gulf of Aden".

The US military also said it struck "multiple Houthi one-way attack uncrewed aerial vehicles, or drones, and an anti-ship cruise missile over the Red Sea".

American F/A-18 Hornet fighter jets were used in the operation, the US Central Command added.

Since November 2023, Houthi missile attacks have sunk two vessels in the Red Sea and damaged others. They have claimed, often falsely, that they are targeting ships only linked to Israel, the US or the UK.

Last December, the US, UK and 12 other nations launched Operation Prosperity Guardian to protect Red Sea shipping lanes against the attacks.

A Houthi missile hit Tel Aviv on Saturday with 16 people being treated for minor injuries

On Saturday, Israel's military said its attempts to shoot down a projectile launched from Yemen were unsuccessful and the missile struck a park in Tel Aviv.

Magen David Adom (MDA), Israel's emergency medical service, said it treated 16 people who were "mildly injured" by glass shards from shattered windows in nearby buildings.

Another 14 people suffered minor injuries on their way to protected areas were also treated, it said.

A Houthi spokesman said the group hit a military target using a hypersonic ballistic missile.

Earlier this week, Israel conducted a series of strikes against what it said were Houthi military targets, hitting ports as well as energy infrastructure in the Yemeni capital Sanaa.

Houthi-run Al Masirah TV reported that nine people were killed in the port of Salif and the Ras Issa oil terminal.

The Houthis have vowed to continue their attacks until the war in Gaza ends. The US says its latest strike is part of a commitment to protect itself and its allies.

'Anger is replacing grief' says mum after daughter died fighting for cladding justice

Walker family Amanda Walker, a woman with blonde hair and smiling, against a red backdropWalker family

Amanda Walker felt trapped in a flat she couldn't sell because of its flammable cladding.

When it turned out that no government scheme would cover the costs of removing the dangerous material from her newly built flat in south London, she started campaigning.

She spent four years trying to get justice for herself, and for millions caught up in the scandal exposed by the Grenfell Tower fire.

Then, at the age of 51, she was found dead in her one-bedroom apartment by her mother and sister. An inquest recently recorded a verdict of death by misadventure.

"She would often phone me late at night when she just couldn't deal with it any more," her mother Glenda recalls.

"I wish she could phone me now."

Amanda's one-bedroom flat, which she bought for £500,000 in 2018, soon became a nightmare

Half a year earlier, in July 2023, Amanda had addressed peers in the House of Lords investigating the impact of the cladding problem on flat owners.

"It's devastating. It's just a quagmire. It's just chaos," she told them. "It's so unjust. I had done nothing wrong and it's destroyed my life already."

The video of Amanda's address to the Lords is now treasured by her mother, who's speaking for the first time since the inquest's verdict.

Glenda thinks Amanda, an office manager at a hedge fund in the City of London, started drinking to deal with the anxiety of having to face unaffordable bills to fix the cladding, running into the tens of thousands.

"I'm not ashamed for her for that because it was her way of coping. She used the term 'seeking oblivion'."

Amanda wrote countless letters to MPs, local authorities and other responsible bodies - but "always got the statutory response", her mother continues.

"There are still over a million people in this situation and [MPs and civil servants] would write these platitudinous letters saying 'oh we're doing this, we're doing that'."

She doesn't just see those as unhelpful - but as evidence that nobody really understood the scale of the problem and how seriously it was affecting people.

It felt like there was a black chasm ahead, Amanda Walker told a House of Lords briefing

The government did eventually launch a scheme - the Building Safety Fund - to pay to remove the type of dangerous cladding that is on the outside of Amanda's flat.

She was hoping that changes enshrined in a separate landmark law called the Building Safety Act - brought in after the Grenfell tragedy - would help her correct internal fire safety defects, like insufficient fire stopping between flats.

But they didn't. There were significant exceptions to who qualified.

Since some of the other flat owners in her development had bought a share of the building's freehold, she became what's known as a "non-qualifying" leaseholder - meaning she still faced huge uncapped bills to contribute towards the repair costs.

Several proposed amendments to the Building Safety Act that would've protected people in Amanda's position were voted down in the last parliament.

What always scared Amanda was the threat of having to pay unpayable sums. She described it as a "sword of Damocles over my head for three long years". For a brief moment there was hope. "And then they vote against us, on everything," she told peers.

Amanda, pictured here with her brother and parents, became consumed by anxiety about her situation

Amanda's drinking increased and her family sought medical help. She agreed to be hospitalised. GPs and psychiatrists were clear in their reports: Amanda's drinking, stress and anxiety were down to the impact of the cladding crisis on her mental state. She was prescribed anti-depressants.

She continued campaigning with her mother, but things began to spiral downhill.

Glenda believes the anti-depressants she was given were not benefiting her. "I think she was over-medicated and her head was all over the place. She wasn't depressed, she kept saying: 'I am not depressed, I'm angry.'"

Amanda's partner split up with her as cladding campaigning consumed more and more of her life. Her mother and sister would make trips to see her to try to offer support.

Glenda says Amanda had entirely lost faith in the government and believes medication was not helping her

Things came to a head one day this January.

Glenda was growing ever-more nervous about her daughter, and knew she needed urgent medical attention.

She says she'd written a "fairly assertive" letter to a hospital where her daughter had been previously treated, warning her condition was getting serious.

Travelling to London through the rain, she found herself "phoning and phoning and phoning" the hospital to try to get doctors to intervene again.

The following day Amanda was found dead.

Asked if she'd ever thought that her daughter might kill herself, Glenda says: "Manda had talked about it. She'd talked about it."

She says she can understand her daughter's state of mind that weekend.

"Yeah, I've seen it so often. I'm different from her and she felt despair… She wanted justice and she felt it was just awful. I think she lost faith in the government completely."

Amanda's parents, who still haven't been able to sell the flat, hope their daughter's campaigning will make life easier for people stuck in buildings with defective cladding

The government says that work is already underway through the Remediation Acceleration Plan "to make sure those responsible for the cladding crisis pay their fair share".

It says it is "continuing to look at all options to ensure residents no longer have to deal with the nightmare of living in unsafe buildings".

Amanda's flat has now passed to her parents to deal with.

Its exterior cladding has now been replaced and they are trying to sell - but they still haven't been able to, due to structural fire issues inside the property.

Unless the Building Safety Act is amended by fresh legislation, Amanda's parents or any future purchaser will be liable for paying to fix those problems.

Amanda's mother hopes that speaking about her daughter's death has not been in vain, and that her story can be a catalyst.

"You go through grief… and perhaps the anger's getting in there a little bit now.

"For her sake, we'd love to think that she had caused some small change."
