Israeli forces have recovered the body of one of the hostages from Gaza, the Israel Defense Forces (IDF) has said.

The army confirmed that Ron Benjamin, 53, was found alongside the bodies of three other hostages whose identities were confirmed on Friday.

The 53-year-old had been taking part in a group cycle ride near the Gaza border when the Hamas attack began on 7 October.

About 1,200 people were killed during the unprecedented attack when Hamas gunmen burst into Israel. They took 252 others back to Gaza as hostages.

News of Mr Benjamin's death comes one day after Israeli authorities confirmed they had recovered the bodies of three other hostages - Shani Louk, Amit Buskila, and Itzhak Gelerenter.

Georgia president vetoes 'foreign agent' law

  • Published

Georgia's president has vetoed a divisive "foreign agent" law that has sparked weeks of mass street protests.

On Tuesday MPs passed the controversial law which requires NGOs and independent media that receive more than 20% of their funding from foreign donors to register as organisations "bearing the interests of a foreign power".

Salome Zourabichvili said the law "in its essence and spirit, is fundamentally Russian" and an obstacle to Georgia's path to EU membership.

However, her veto is only symbolic as the prime minister's Georgian Dream party has enough members in parliament to override it by holding another vote.

In a televised address broadcast on Saturday, the president said her veto was "legally justified".

"This law cannot be a subject to any change, improvement and embellishment, and thus it’s a very simple veto. This law must be withdrawn, " she said.

Ms Zourabichvili - an opponent of prime minister Irakli Kobakhidze - was widely expected to veto the law.

Meanwhile, Mr Kobakhidze has called on youth protesters to select at least 10 representatives to join a public discussion with him on the controversial law.

According to The Interpressnews agency reported on Friday, he said: "I am ready to not only listen to their critical remarks, but in specific cases, share them. I expect the same attitude from youths."

Critics say the law is inspired by authoritarian legislation neighbouring Russia uses to crush dissent.

Some are concerned that the law will derail the country's path to EU membership as conditions for membership involve candidate countries implementing reforms on democracy and the functioning of the state, the rule of law, fundamental rights and reform of public administration.

Georgia was granted EU candidate status in December 2023.

Massive rallies against the bill have gripped the Caucasus country for nearly a month. Photos and footage posted online in recent days appeared to show violent altercations between protesters and police.

Thousands of people who were having to boil their water in Devon due to a parasite outbreak are being told they no longer have to.

South West Water (SWW) said it was no longer advising 14,500 households in Brixham to boil their water before drinking it.

The company said 17,000 households and businesses had been affected by the boil water notice after traces of cryptosporidium, a parasite that causes diarrhoea, was identified in its network on Wednesday.

It is still advising about 2,500 properties in Hillhead, upper parts of Brixham and Kingswear to continue to boil their drinking water.

Hillhead reservoir is being investigated as the source of contamination

Health officials have said there are 46 confirmed cases of cryptosporidiosis linked to the outbreak, with more than 100 other people reporting symptoms.

Conservative MP Anthony Mangnall, whose Totnes constituency covers Brixham, welcomed restrictions being lifted, but said the situation had been "totally unacceptable".

“I share the anger of the residents of Brixham and the surrounding area, and we need clear answers as to why this has happened and what has caused it," he added

Laura Flowerdew, SWW's chief customer officer, apologised for what happened.

"This situation has caused an immense amount of disruption, distress and anxiety," she said.

"We are truly sorry this has happened."

Increased compensation

The water company said it was increasing the compensation offered to the remaining affected residents by £100, bringing the total they will receive to £215.

SWW said a damaged valve on private land in the Hillhead supply area was identified as the "possible cause of contamination".

It said the area had "since been isolated from the network and repaired".

The water company said people who are unsure if they remain in the area affected by the parasite should visit its postcode checker, external or call them.

Speaking to the BBC, Ms Flowerdew could not say when the boil water notice would be lifted for the remaining 2,500 properties.

"We are expecting that work to continue over the weekend and into next week," she said.

"Public health is absolutely critical... so we are looking to ensure we have done everything we need to before we lift the notice.

"We are expecting this to extend a number of days."

The water company on Tuesday said tap water in the town was safe to drink, but U-turned less than 24 hours later and advised residents to start boiling their water.

Residents have expressed anger at SWW's communication since the start of the parasite outbreak.

Asked about the U-turn, Ms Flowerdew said: "All the decisions we have made have all been evidence-based.

"When we issued the notice on Tuesday, we had no indication the water supply had signs of the cryptosporidium in it.

"As soon as we got information that provided sound evidence - we put a notice in place."

Ms Flowerdew said the firm would be looking for "evidence" supporting the water was safe to drink before the boil notice was fully lifted.

“The important thing now is to look in the Hillhead area and make sure we have absolutely confirmed the source of the issue and to fix that issue," she said.

"Public health is of paramount importance."

Michaela Lewis said she was "very angry" with South West Water's response

Mother-of-two Michaela Lewis said she no longer had confidence in the quality of the water supply.

She said her five-year-old daughter had been unwell for about two weeks.

"I'm very angry," she said.

"I understand these things happen, the response is what's really angered me.

"It's just not good enough... to say they water was safe when they didn't have adequate evidence to back that up."

Ms Flowerdew said in response: "As a mother myself, I find that incredibly distressing and I can only apologise."

Thousands of pro-Palestinian protesters marched through central London on Saturday, reiterating calls for a ceasefire in Gaza.

The protest marked the 76th anniversary of what Palestinians refer to as the Nakba - the mass displacement of people after the creation of Israel in 1948.

The Metropolitan Police said it had held "regular discussions" with organisers the Palestinian Solidarity Campaign to minimise disruption.

A counter-demonstration by pro-Israel group Enough is Enough took place at Piccadilly Circus at the same time.

Ch Supt Colin Wingrove, leading this weekend’s policing operation, said: "All Londoners have a right to have their voices heard, just as they also have a right to go about their lives without fear or being subject to serious disruption."

The pro-Palestinian march was the 14th such event held in London since the Hamas attack on Israel on 7 October, in which 1,200 people were killed and more than 240 kidnapped.

After the 7 October attack, Israel launched an offensive in Gaza that has killed more than 35,000 people, according to the territory's Hamas-run health ministry.

Demonstrators, some carrying "ceasefire now" placards, were heard singing and chanting as they made their way from Regent's Street to Whitehall, where they gathered for speeches.

One protester, Sandi, a Palestinian who has family in Gaza, said that she had not heard from her relatives there for the last 10 days.

"The internet connection is down, so sometimes it's longer - weeks - that I don't hear from them," she told the BBC.

"Like everyone else in Gaza, they're suffering from a lack of safety, access to food, internet, medical aid and freedom of movement."

Stephen Kapos, a Holocaust survivor, said he was attending the march to express solidarity with the Palestinian people and to protest against what he described as Israeli leaders' "misuse of the memory of the Holocaust".

"It is an insult to my family, an insult to the memory of the Holocaust and an insult to the suffering of that period. I'm protesting against that. Not in our name," he said.

The Palestinian Solidarity Campaign said demonstrators were calling "again for action to end the genocide in Gaza".

The UN's top court, the International Court of Justice (ICJ), is considering a case brought by South Africa in January accusing Israel of committing genocide against the Palestinians in Gaza.

Israel has rejected the claim as false and "grossly distorted".

The ICJ is not expected to deliver a ruling on the genocide case for several years.

Customers have been unable to use Marks and Spencer's website and app for several hours after it was hit by a technical issue.

The website temporarily came back online but ongoing issues remain.

Users see an error message on the homepage and cannot navigate to any part of the website.

An M&S spokeswoman told the BBC a problem with a third party provider was "temporarily affecting access".

The company added: "We hope to be back up and running soon and are sorry to customers for the inconvenience caused."

Problems with access to the website and app were first reported on X, formerly Twitter, from around lunchtime on Saturday.

The website came back online just before 17:15 BST for a short time before returning to the original error message. The app is still showing a notice about a technical glitch.

It said: "Sorry you can't shop through the app right now.

"We're busy making some planned changes, but will be back soon."

Some customers complained on social media that they had been unable to use their Sparks card - the company's loyalty scheme - as they did not have a physical card and claimed they had lost out on savings.

In March, supermarket Sainsbury's was also hit with technical issues. It was unable to carry out most of its online grocery orders after an overnight update caused contactless payments to fail.

新华视点·聚焦中央生态环保督察|围湖造地、圈水养殖……鄱阳湖水域非法矮围何时休?

By: 新华社

新华社

本应完成治理的非法矮围仍清晰可见、本应禁捕的水域依然盗捕横行、本应波光粼粼的湖面变成了农田牧场……

“新华视点”记者日前随中央第三生态环境保护督察组在江西省鄱阳湖区南昌、九江、上饶等地调查发现,鄱阳湖水域非法矮围治理流于形式,大量非法矮围仍在威胁着鄱阳湖的保护修复。

非法矮围依然可见

矮围,通常指湖里筑起的矮坝。它把一片水域围起来,或是围湖造地用于耕作,或是拦水筑塘用于捕捞养殖。矮围会阻断河湖水系连通,影响湖区水质。

2020年8月,国家有关部门要求开展长江流域非法矮围专项整治,对重点水域内非法设置的用于捕捞、养殖的矮围开展清理取缔,做到全面排查、应清尽清。

然而,记者5月14日随督察组前往鄱阳湖南矶湿地国家级自然保护区时发现,虽然近期鄱阳湖水位大幅上涨,但通过无人机航拍发现,大量本应在2021年4月基本清理完毕的矮围堤坝仍清晰可见。

非法矮围治理流于形式,是当前鄱阳湖生态环境保护存在的主要问题之一。

4月9日,督察组在鄱阳湖南矶湿地国家级自然保护区拍摄的非法矮围(无人机航拍)

记者从督察组了解,在长江流域非法矮围专项整治中,鄱阳湖水域是由乡镇和县级政府自行上报区域内非法矮围情况,再由省级相关部门督办开展集中整治。

“整个过程中,没有任何部门对上报范围之外的矮围实施鉴定排查。从这次督察暗查的情况看,还有很多非法矮围依旧存在。”督察组成员说。

今年4月督察组暗查时,面积约2000亩的鄱阳县朗埠圩正在外排养殖尾水,监测结果显示水质为劣Ⅴ类。已经整治销号的九江共青城市红星圩内依然有养殖行为,还投粪用于肥水。督察组暗查后,地方再次排查,又发现了44个用于水产养殖的非法矮围。

据介绍,目前鄱阳湖水域还有大量矮围有待排查、整治。

专家表示,矮围阻断了天然的河湖连通,人工养殖使得周边水域水质污染严重;今年“五一”期间,大雨过后、湖水大涨时,这些污水流入湖中,直接影响水体质量。

围湖造地危害水体质量

水法明确规定,禁止围湖造地。2021年11月,国家有关部门关于加强长江经济带重要湖泊保护和治理的指导意见明确,禁止围湖造地,有序实施退地退圩还湖。

记者与督察组一起前往南昌县大沙坊附近看到,一些围垦的土地虽然已经被鄱阳湖水覆盖,但此前耕作的痕迹依然明显,大量建筑垃圾被用于填充连接矮围和岸边堤坝的道路。

4月15日,督察组在南昌市新建区与南昌县交界的沙叉河水域拍摄到的画面,滩涂湿地被围垦用于商业草坪种植,大部分春季草坪已经出售并交付。(无人机航拍)

“这些都是用来种植商业草坪的土地,在我们前期暗查时,鄱阳湖水位还没有上涨,这上面的草皮非常清楚。”督察组成员说,这样的情况在当地还有不少。

2021年,上饶市余干县将塘背圩内857亩湖泊水面疏干、填土后变为农田;南昌县磨盘洲矮围应退田还湖,但圩堤被重新封堵,矮围内2500亩湖泊滩涂变为农田……

大量用于耕作的围垦地不仅导致湖区水域面积大量缩减,而且也是鄱阳湖的重要污染源。

近年来鄱阳湖总磷浓度一直未达到湖库Ⅲ类水标准。督察组调查显示,2023年,湖区18个国控断面中仅5个总磷浓度达标;9个断面总磷浓度同比不降反升,最高上升39.6%。

在南昌县、永修县,湖区围垦的农田田埂现场,废弃农药包装随处可见;监测结果显示,农田沟渠水总磷浓度超湖库Ⅲ类水标准3倍至13倍。当地一些种植大户表示,一直都在施用化肥,并没有采取什么减量措施。

 4月18日,督察组在上饶市余干县狗尾洲洲滩发现,有大量牛群在洲滩围垦地上放养。(无人机航拍)

此外,记者在湖区的一些围垦地看到,《鄱阳湖生态经济区环境保护条例》中封洲禁牧的规定没有得到严格执行,仍存在不少畜牧养殖行为。

“我们暗查时看到,洲滩湿地还存在畜牧养殖问题,粪便成堆、污水横流。这些污水没有经过专业处理直接排放到湖中,对水体质量危害很大。”督察组成员说。

禁捕落实不到位 连累“国宝”江豚

长江江豚,是全球唯一的江豚淡水亚种,国家一级保护动物,被称作长江生态的“活化石”和“水中大熊猫”,仅分布于长江中下游干流以及洞庭湖和鄱阳湖等区域。

“我们看到了江豚,却不是我们愿意看到的样子。”督察组成员指着一张航拍的照片说,“这是一头被困于油污区域的小江豚。”

3月24日,督察组在江西九江港星子港区沙山作业区综合码头建设现场拍摄到的画面(无人机摄影截图)。经中国科学院水生生物研究所专家判定,被困油污之中的是一只幼年江豚。

这是督察组3月底在江西九江港星子港区沙山作业区综合码头建设现场拍摄到的画面。此处距鄱阳湖长江江豚省级自然保护区核心区仅2.7公里,施工应避开3月至6月鱼类繁殖期。

然而,督察组成员3月底暗查时发现,该综合码头建设工程正在违规进行疏浚作业,疏浚产生的泥沙将部分岸边水域吹填成陆地。3月22日和24日,疏浚船只两次发生漏油事故,建设单位未采取应急处置措施,放任油污污染周边湖面。

据了解,2022年至2023年,鄱阳湖内发现有5头江豚死于渔网和鱼线缠绕,占这两年已统计死亡江豚数量的20%。

“受伤”的江豚背后,是地方对重点水域禁捕要求落实不到位。

2019年江西省主管部门明确鄱阳湖禁捕范围为湖体水线及五河干流入湖口以内水域,但是2021年4月公告的拐点坐标中,部分矮围集中区域未划入禁捕范围。

今年3月底,督察组成员在九江市庐山市湖区暗查时发现,有人数较多的盗鱼团伙,在面积1万亩的长湖圩内,使用拉网、电鱼等方式非法捕捞。

长江大保护,功在当下,利在千秋。如何将生态红线转化为生态红利,关键还在地方政府。

日前,记者在鄱阳湖部分问题突出的水域看到,有些整治工作已经开始。一些围垦地上的非法建筑正在拆除,大批牛群正重新返回陆地,围垦地上的种植物正在清除中。

专家建议,通过此次督察,当地相关部门应当在鄱阳湖重点水域对非法矮围问题开展集中排查整治工作,有效解决鄱阳湖保护修复中长期存在的问题,实现生态环保和经济发展的双向促进。

东莞长安镇,昔日的电脑配件厂完成转型,一批智能手机零配件送进龙头企业,走向全球市场;佛山南海丹灶镇,一座五轴激光数控机床下线,硬脆材料加工难题迎来解决方案……从珠三角到粤东西北,无数个这样的瞬间,连成一条45年的长轴,造就了广东在经济总量、市场主体总量等多个“全国第一”,也由此诞生出4座万亿级城市,第三、第四座“千亿镇”亦呼之欲出。

庞大的市场规模,丰富的市场主体,也演奏着竞争与合作的复杂旋律。广东如何在其中寻得平衡,激发活力?连日来,记者随“高质量发展调研行”广东主题采访活动,走访了珠三角地区多家在行业内处于领先地位的企业。从研发创新到市场拓展,从供应链管理到金融助力,这些企业通过不断探索和实践,正逐步构建起具有广东特色的企业生态体系。

高质量发展调研行采访团走进广东省科学院佛山产业技术研究院孵化的半导体封装测试平台。

龙头企业牵引能力“外溢”

一镇千企形成完整生态

驱车走在东莞长安镇的街道上,目之所及的是鳞次栉比的电子信息工厂。在这座电子信息重镇,工厂不少都是OPPO、vivo两大智能手机品牌的供应商。

20年前,长安镇的电子信息产业原来以台式电脑零配件为主。当时,一部台式电脑的零配件,基本上可以在长安或者周边区域找到。

随着龙头企业OPPO、vivo的崛起,长安的电子信息企业也逐步向智能手机零配件转型,并且随着产业的新风口,部分企业同时向新能源配套方向转型。

长安镇党委副书记戴浩平介绍,目前,头部企业的上下游配套企业总共有1000多家,相关从业人员超过20万人,形成以龙头企业为引领、产业链上下游协同的完善产业生态。

龙头企业这种强大的牵引能力还在持续“外溢”至相关产业。

在长安镇,电子信息和五金模具两大产业雄厚的产业基础,加之两大龙头企业OPPO、vivo的产品需求,催生了一个快速增长的产业——机器视觉。

戴浩平说,长安的机器视觉产业已经初具规模,2023年规上机器视觉产值超过80亿元,拥有宇瞳光学、奥普特等上市企业,以及光志光电、瑞谷光网、三姆森等后备上市企业。

一个产业就是一个生态系统,系统内上下游企业、产业链、供应链、创新链等环节环环相扣。而南粤大地上,一批“链主”企业正逐渐在竞争赛道上跑出优势。

根据《广东省战略性产业集群重点产业链“链主”企业遴选管理办法》,“链主”是处于产业链供应链核心优势地位,对于优化资源配置、技术产品创新和产业生态构建有重大影响力的企业。广东拓斯达科技股份有限公司(以下简称“拓斯达”)就是其中之一。

5月17日,“高质量发展调研行”广东主题采访活动走进拓斯达。图为拓斯达的机械臂。

拓斯达的工厂内,一排排四轴机器人整齐划一地左右摇摆,进行着老化测试;从接单到生产,从备料、入库到出库,都可以通过数字化看板完成……自入选广东省首批“链主”企业以来,拓斯达从起初主要面向消费电子产业的工业机器人和数字化解决方案起步,业务逐渐发展到整车企业,进而切入汽车自动化装备。

“随着产业链条的完善,服务也在不断延伸,围绕第三方维修保养团队、二手设备经销商、金融服务体系,形成了完整的产业链闭环。”拓斯达副总裁、董事会秘书谢仕梅介绍,“如今,我们同时布局机器人、注塑机、CNC产品,这些是制造业所需的三大通用设备,下游几乎覆盖所有制造业。”

目前,拓斯达已形成工业机器人及自动化应用系统、注塑机及其配套设备、数控机床、智能能源及环境管理系统四大主营业务板块,产品销往亚洲、北美等多个国家和地区。

研发实力、核心技术水平是衡量“链主”企业的重要指标之一。2022年,凭借强大的研发投入、人才培养与研发平台建设,拓斯达多项核心技术再次取得突破性进展,工业机器人及自动化应用系统业务全年实现营收近13亿元;2023年,拓斯达多关节工业机器人出货约1700台,自产多关节工业机器人收入同比增长48.55%。

“专精特新”企业瞄准缝隙市场

强链补链建立竞争优势

瞄准“缝隙市场”,“专精特新”企业在细分领域建立竞争优势,有效连接产业链断点、疏通堵点,撑起广东未来的先进制造业版图。

走进广东原点智能科技公司,工程师们正加紧调试已经组装好的五轴激光数控机床。“我们激光数控机床的核心部件已基本实现国产化,国产化率达到90%以上。”该公司副总经理刘志峰自豪地说。

高质量发展调研行采访团走进广东原点智能。

对于硬脆材料的加工,传统方法是用砂轮磨削,而五轴联动激光加工则以激光替代砂轮,通过精准控制激光在三维空间内的移动,实现对复杂精密结构的低损、高效加工。

作为国家专精特新“小巨人”企业,原点智能着力打造聚焦“工业母机”的“大脑”,主要进行五轴及其以上多轴联动数控系统的研发、生产和制造,结合数控系统和工业软件提供以激光数控机床等为核心装备的智能工厂解决方案。

刘志峰告诉记者,近3年,原点智能的营收连续倍数增长,企业保持每年销售额的20%研发投入,销售价格是国外设备一半或三分之二,新工厂建设总投资额超2亿元、建筑面积近5万平方米。

在工业领域,有这样的一个群体,他们可能不为大众熟知,但在其所在的细分市场生产技术或工艺国际领先,单项产品市场占有率位居全球前列。这些企业,被称为制造业单项冠军。

鼎泰高科工厂内,刀面机正在检测钻头尺寸。

广东鼎泰高科技术股份有限公司(以下简称“鼎泰高科”)就是其一,凭借PCB微型刀具领域的领先地位,该公司今年3月获评第八批国家级制造业单项冠军产品企业。

PCB微型刀具是加工PCB(印刷电路板)的工业用微型刀具,由于PCB被广泛应用于消费电子、5G通信基站、汽车电子等领域。

“但2013年,鼎泰高科成立之初,PCB微型刀具以进口为主,价格高昂且受制于国际市场,很多客户都希望有国产的PCB微型刀具。”鼎泰高科董事长王馨回忆,洞察到这个机遇,鼎泰高科紧抓研发,产品在国内市场迅速崛起,实现了跨越式的增长。

其中,90%以上的设备都由企业自主研发,使鼎泰高科受益匪浅。“因为有着一套成熟的自动化设备体系,鼎泰高科才能在产品开发方面做到敏捷高效。去年全年,我们的钻针销量占全球市场份额26.5%,成为全球最大的钻针供应商。”王馨说。

第八批国家级制造业单项冠军企业公示名单中,有包括鼎泰高科在内的61家粤企入选。此前,前七批国家级制造业单项冠军企业名单中,广东累计培育132家,占全国比重11%。

更多“专精特新”“单项冠军”在南粤大地不断崛起,离不开金融“活水”的浇灌滋养。

作为广东(深圳市除外)唯一合法的区域性股权市场运营机构,广东股权交易中心积极打造“专精特新”专板,成为首批与全国股转公司签署绿色通道监管合作备忘录的区域性股权市场运营机构,为全省“专精特新”以及创新型中小企业申请新三板挂牌提供便利机制和绿色通道。“专精特新”专板通过对企业进行分层梯队孵化培育,提供与之相适应的基础服务和综合金融服务。

截至今年4月,广东股交已聚集“专精特新”中小企业和国家级“小巨人”企业超1500家、高新技术企业超6000家,累计培育17家企业转沪深北交易所上市、149家企业转新三板挂牌。

iPhone 的信号问题,可能主要在基站切换策略上

18 May 2024 at 15:54
1014982466: 想客观讨论一下,首先我发现很多人似乎完全不知道“控制变量”这个东西。
经常看到“我的同事和我一起吃饭,它的 XXX 付款码马上加载出来了,我的 iPhone 一直转圈”。

现在大部分地区的基站并不是共享,你好歹先看下你们分别是什么运营商吧。
还有就算是同一个运营商,现在速率和 QoS 优先级也是不一样的,我自己在用的联通速率就分了好几档,更别说还有提速包/手游加速包这种额外付费提升优先级的增值服务。

我个人做了一些测试,在不同静止场景下,用一张 SIM 卡,iPhone 15 Plus ,14 Pro 和一些常见安卓手机,用一个 SpeedTest 服务器测试,速度没有什么统计学上的差异。
但是上次出游,在高铁和地铁上,进行同样测试,发现 iPhone 的网络质量就有明显下降。

我合理推测:
0 ,对当下网络质量影响最大的是基站覆盖,有问题先打客服电话。
1 ,iPhone 的基带和天线在当下,都不是问题(旗舰机都是高通的基带,能有啥本质上区别)。理论性能都远远超过生活中的运营商提供的速率。
2 ,iPhone 在静态场景下,测速一般都能跑到套餐理论速率,和主流安卓旗舰机没有区别。
3 ,iPhone 的网络调度偏向于节能。
4 ,iPhone 总是会尝试尽可能使用正在连接的基站,切换阈值设定不合理,不去主动搜索新的基站,而且主动搜索的间隔很长。这导致了,在地铁和高铁这种频繁切换的场景,iPhone 这种消极策略在一些覆盖率不佳的线路上,会断网很长时间。
5 ,我猜测安卓厂商的一些高铁优化技术,可能就是减少切换阈值,增加切换速度。

欢迎提供更详细的技术资料和讨论

如何确定自己的安卓机有没有 root?

chouxw112233:

已经解了 bl 锁。 我刷了 magisk ,也 fastboot boot magisk_boot.img 重刷了 boot.img ,能够在 magisk 上管理 root 权限

>adb shell
wayne:/ $ id
uid=2000(shell) gid=2000(shell) groups=2000(shell),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),1078(ext_data_rw),1079(ext_obb_rw),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc),3011(uhid),3012(readtracefs) context=u:r:shell:s0
wayne:/ $ su   # 这一步会在手机上提示是否允许 root
wayne:/ # id    # 如果我的理解没问题,我可以切换到 root 用户,说明我应该有 root 权限
uid=0(root) gid=0(root) groups=0(root) context=u:r:magisk:s0

但是我始终无法把根目录挂载成 rw

wayne:/ # mount | grep "/ "
/dev/block/dm-0 on / type erofs (ro,seclabel,relatime,user_xattr,acl,cache_strategy=readaround)
wayne:/ #
wayne:/ # mount -o rw,remount,rw /
wayne:/ # mount | grep "/ "
/dev/block/dm-0 on / type erofs (ro,seclabel,relatime,user_xattr,acl,cache_strategy=readaround)
wayne:/ #

用 MT 文件管理器(打开时会提示 root ),在根目录上创建一个文件夹,也提示挂载读写失败 似乎我的 root 是个假 root

我不喜欢蒂姆·库克的原因

doggg:

2018 年我购买了人生中的第一台苹果设备 —— MacBook Pro 2018 ,作为陪伴我三年的 Dell Inspiron 7558 2-in-1 的继任者(时至今日,它依然是我最喜欢的笔记本电脑)。

这台苹果笔记本在蒂姆·库克作为 Apple CEO 的时期内,“革命性”地采用了 OLED 显示屏、Touch Bar 和蝶式键盘,并在发布会上被大肆宣传。实际使用下来体验非常糟糕,Touch Bar 上的触摸功能键经常让我在调试程序时按错键,蝶式键盘特别容易出现按键粘连,作为不使用外置键盘的程序员来说,这简直就是灾难。而且不到两个月,OLED 屏幕四周就开始泛黄,烧屏。 这样的一台「库克制造」电脑在当时花费我两万块钱。而苹果糟糕的售后预约制度和(当时)动辄一周的维修时间让我放弃了维修的打算。

后来 MacBook 终于移除备受争议的蝶式键盘。Touch Bar 是在 2021 年取消的,同时,库克居然把 iPhone 的刘海屏移植到 MacBook 上。也就是说,从 2015 至今,MacBook 用户至少要经历蝶式键盘、Touch Bar 或刘海屏,而我一次体验其中两种。

作为苹果用户,我很难想象在库克的时期里,这十年来是如何做到每一代 MacBook 至少包含一种缺陷。制造一台基本完美的电子设备对一家市值常年世界第一的企业来说是否非常有挑战性?如果把库克当成一名商人,商人的目的就是贩卖商品,那库克一定非常出色的商人。库克时期以来制造的这些不完美的电子设备,甚至动用降频手段来刺激更新换代,把苹果的市值从几千万推到了最高三万亿。作为苹果用户,我一点也不喜欢库克。但从投资的角度来说,我又会用一套完全相反的说辞来说服自己购买苹果股票。2020 年我通过基金也间接重仓了苹果,见证苹果短短半年从 1 万亿涨到 2 万亿。

苹果的库克时代在 2024 好像悄然翻篇,造车计划终止、错失 AI 时代、营收下滑、Vision Pro 销量不佳… 即使站在投资的角度我也很难再找到说服自己看多苹果的理由。

库克时期内的苹果,充斥着商品的气味,缺乏划时代的创新。

openwrt 二级路由下 ipv6 设置不生效

By: Kalan
19 May 2024 at 00:15
Kalan:

背景

  • 光猫桥接;
  • 主路由拨号,设备连接后可以通过 ipv6 test ;
  • 二级路由(华硕 AC88U 刷了 ImmortalWrt 官方固件),配置 ipv6 中继模式,电脑可以获取到 ipv6 地址,但无法访问 ipv6 站点(连接主路由 wifi 可以访问);

二级路由配置

config dhcp 'lan'                                                                                 option interface 'lan'                                                                     option start '100'
        option limit '150'
        option leasetime '12h'
        option dhcpv4 'server'
        option ra 'relay'
        option dhcpv6 'relay'
        option ndp 'relay'

config dhcp 'wan'                                                                                 option interface 'wan'                                                                     option ignore '1'
        option ra 'relay'
        option dhcpv6 'relay'
        option ndp 'relay'
        option start '100'
        option limit '150'
        option leasetime '12h'

config dhcp 'wan6'
        option interface 'wan6'
        option ignore '1'
        option master '1'
        option ra 'relay'
        option dhcpv6 'relay'
        option ndp 'relay'

二级路由防火墙入站出站转发均为接受;

PS: 网上看了很多类似配置教程,基本都不生效,不知如何解决。
