想买一款集合 wifi+2.5G 以上的 PCI-E 设备 但似乎没有。

leafyyy: RT 最近发现 pci-e 的 BE200 无线网卡测速总是很迷幻。
跑下来能跑起速度,但是有时使用科技大学的测速节点测试下来下载甚至只有 10Mbps 都不到的速度。但同时我 PC 到 NAS 的内网速度传大文件速度又是正常的 1.5Gbps+

换上网线后科技大学测速正常了。 所以感觉可能是晚上家里 wifi 使用的设备变多了(家里父母到家 手机都在刷视频看直播等) 导致 wifi 性能下降。

路由器是华三的 NX15000 要说性能不足吧这玩意儿也不应该 但是还是保持怀疑。 但是实在无法排查问题到底出在哪里了。

因为台式机是小板 显卡占用一条 PCI-E X16 后 风扇就硬生生占据了一条 PCI-E X1 。 只剩下一条 PCI-E X4 给了现在的 WIFI7 无线网卡了。

搜了下 并没有符合我需求的设备。 所以上来问问大家有见过类似的设备么。 或者现有还有能解决我需求的方法及问题点 我也好对症去解决。

大型多模块 Java 项目你们用什么构建工具

movq:

比如这样的项目结构,有时候各种模块之间依赖比较复杂,C 依赖 B 的代码,改 C 的时候可能会进去 B 改。

root/
  moduleA/
  moduleB/
  moduleC/

对于 Maven 这种构建工具,不支持增量编译,所以得全部重新编译才行。对于大型应用这样就太费时了。(不清楚为什么这么流行,感觉很奇怪)

而 IDEA 、Eclipse 这种 IDE 自带的构建系统,都支持增量编译。如果只改了几行,就秒编译了。

至于 Gradle ,它除了和 IDE 无关,所以能够解除和具体 IDE 的绑定之外,有什么别的优点呢

避雷小鹏汽车

pdog18:

5 月底的时候入手一个小鹏汽车 p7+,以下是我的一些感觉,如果小鹏的产品在你的意向中的话还请慎重考虑:


p7+ 使用个人主观体验

  1. 雨感垃圾,等到看不清才刮(安全相关)
  2. 转向灯拨杆段落感不清晰,很容易变道灯打成转向灯
  3. 贴膜(官方商城的膜)后左侧空调出风口反光严重影响后视镜视线(安全相关)
  4. 倒车影像下雨天很容易模糊看不清
  5. 行车记录仪像素太低,不如 200 块的盯盯拍清晰

最最!!!!!!! 我的 p7+ 转弯和调头时电门有几率失灵,失灵的时候车头引擎盖下有明显的异常声音(类似齿轮无法正常咬合一样)!!!!!!!!!!!

提车一个多月起码遇到 5 次了,管家群上传日志分析后说正常输出扭矩。我能肯定不是个例,有其他 p7+ 车友一样也遇到过。

如果能再来一次的话,我绝对不会买小鹏的任何产品,现在每次下雨天开车,打转向灯的时候和转弯需要踩电门的时候都是一种煎熬。

如何强制关闭网页检测 F12.一打开就自定关闭网页了.

chrosing: 各位大佬好,我是一名 Java 后端开发,最近在研究生成 TRC20 ( Tron )靓号地址的方式。偶然发现了一个网站 https://tronscan.pro/ ,看起来可以自动生成 Tron 地址,想看看是否有暗门或者后门之类的.

但我遇到两个问题:

打开开发者工具( F12 )时,页面会立即关闭;

我使用 ai 提供的篡改猴的脚本屏蔽,但还是失效;

我的问题是:

有没有比较有效的方式绕过该网站的 F12 关闭机制?

感谢各位指点!

(我已经用 Java 生成了一批地址可以选择)

网球学习半年花费 1w 了,值吗?

HariopaNic:

去年年底开始学习打网球,陆陆续续上了 15 节课,列一下这段期间的网球开销;

装备:

1 、网球拍,head l5 mp ,2k ;在选择人生第一把网球拍的时候,我考虑的因素有颜值,特别想要一把全黑的拍子;耐用,这把拍子最好能陪伴我很久;品牌,当时只考虑了 head, wilson,yonex 这三个牌子。于是在参考了很多推荐之后,我选择了 head l5 mp ,这把拍子挺热门,有溢价,但能接受。于是在双十一下单了,加上几个球,穿线服务, 避震器等一些小玩意,总计花费 2k 。

2 、网球鞋,nike zoom vapor pro ,559 。这个鞋子是我打了两个月网球之后买的,因为刚开始都不知道打网球需要专门的鞋子,在这之前穿空军一号比较多。体验下来, 网球鞋确实包裹性比较好。

3 、帽子,包,500 。帽子是网球人的本体了,就算是室内也得戴着帽子;因为我去打球一般就带球拍和水,所以买了两个斜挎包,但使用频率一般,最后都用家里闲置的帆布袋了。

我买的装备并不算多,都是一些必须性的,像很多女生会买好几套 fancy 的球鞋,网球裙,衣服……一套都上千了。

上课花销:

300 课时费/h + ≈70 场地费/h

我选择的教练是高校在校生,一节课 300 ,不包含场地费。这个价格在上海算刚起步,像一些成绩比较好获奖比较多的在校生,课时费得要 400+了。 选择在校生有一个好处是,他们可以帮订学校的场地,毕竟上海市区的网球场太紧俏了,热门时间很难订。

课后练习:

家附近有一个至臻网球场,学练场 88/h ,单打场 198/h 。 打了几次之后买了至臻的 3000 绩点卡,可以在原价基础上打八五折,目前快用光了。总计感觉花费快 4k 了。

网球学习半年的开销就这些,算下来应该有 1w 了。值吗?太值了!因为网球可太有意思了。

我第一次去打发球机的时候,连球都打不到。但随着自己的思考,感受,领悟,球技越来越好。从打不打球到能打到球,再到能把球打到正常的位置, 动作越来越规范,失误减少,能打半场,再到能打全场。看着自己不断进步,真的很有成就感。

网球是我接触门槛最高的一项运动,很多人上 20 节课才刚刚入门,我算学的比较快的,在 xhs 发了打球视频都是被夸有天赋。 所以想要学好这门运动,需要很大的毅力,同时也不能舍得花钱,因为很多开销都是很有必要的。

顺便在 v 上找一些网球搭子,技术差不多的同好们可以留个 vx ,一起进步,狠狠涨球!

大模型反复犯同一个错误是否和模型精度有关?

jqknono:

我在使用某家的 claude 模型时, 会提供文件和提示词.

每次都新开会话, 提供相同的文件. 仅修改提示词.

发现模型会犯同样的错误, 产生同样的幻觉, 生成同一个错误表达.

我不太懂大模型, 但该模型有时非常的聪明, 有时很蠢. 其蠢法很多时候是反复犯同样的错误, 即使提示了模型注意事项, 模型也不会注意.

我理解大模型实际算的是概率, 多次算对没问题, 多次算错也可以理解, 但多次错的一样, 是否和模型采用的精度有关? 也就是供应商业务繁忙时, 通过降低模型精度以为更多人提供降智的服务?

我不能确认, IDE 们统一叫 claude, 没有带精度信息.

我关注过自部署模型, 一些模型会声称 4bit 性能几乎无损耗, 实际上在真正有难度的问题上差别明显.

claude 供应商有做降低精度这样的事吗?

如果所有 APP 都能通过截图圈出关键功能来快速定位到相关设置页面就好了。可以快速关闭不需要的功能。

evan1:

https://www.v2ex.com/t/1142984?p=1 此贴有感。

现在的 app 有太多我们平时用不到的功能,最常见比如微信、QQ 下面的页签。相关的功能得去设置页面找半天才能找到开关。

如果能长按就能弹出个右键菜单来关闭,或者先截图然后圈一下,然后就能快速跳转到相关设置页面就好了。

如果能搞个插件出来感觉也不错。截图识别 app 类型,然后截图识别功能,然后模拟用户操作自动点击到相关设置页面。

🤪我宣布, 20$一个月的 vercel 根本就不贵!

HeyCaptainJack:

这两天在尝试 nextjs 项目的自部署,先后尝试了几种方式: 1️⃣ 基于 docker 自己部署,还得处理 ci/cd 等自动化流程,而且 2c4g 的在打包的时候,性能根本不够使 2️⃣ 基于 dokploy 部署,同样没有 2c8g 的配置,基本上也是卡死 3️⃣ aws amplify 部署,说实话,跟个残废一样,打包失败,各种环境不支持 4️⃣ 还有本地打包配合 pm2 进行构建的相关的配置尝试

😭而折腾这些,花费了我两天的时间,都够续费多少个月 vercel 了 ps: 别问我为什么要自部署🤪

用文字完整写下自己的想法和困惑,是一件很有帮助的事情

xyzlucky:

职场生活近一年来都很不顺,被骚扰、被无限甩锅,斗争过、反抗过、吵架过。但是心里还是很不舒服,每天看到烂人都特别崩溃。 家人和爱人给了我很多开解,但是我心里还是很犯嘀咕。 斥巨资买了一个说话还蛮一阵见血地博主的课,可以加群咨询问题。昨天又产生了“我要走”的念头之后,觉得这样不可以,其实没准备好现在就提问的,但是决定就好好地整理下我的情况,然后发出去请求答疑解惑。 最开始写第一版本的时候,有条理地讲了所有的故事线,我写了四千多字。然后又重新在这个基础上,我写了两千多字。发出去了。 我的问题其实有三个。她看完之后在群里抓着其中一个显而易见的前置条件不太能转变的点,痛骂我。但是没有回答我的问题,我继续问才给了一个回复。

我其实看到的第一瞬间是很迷茫的,我感觉整个人都崩溃了。所以立刻找妈妈聊天(没错,这么大了还去找妈妈) 但是后来聊着聊着觉得,情况没有这么坏,我还年轻,而且我没有做坏事情。

这件事给我的感悟就是,因为我太想问一个局外人这件事情了,写完之后,整理完之后,我好想可以稍稍放平心态一点了,我慢慢规划,好像事情没到特别特别糟糕的那一步。烂人就烂人吧,我可以走一步看一步,我可以多多规划。

我还是要继续做好事情,保持我的好口碑。 所以也算是一个方法分享吧~祝大家都好

iPhone 16 Pro Max 微信通话,对方听到的声音失真或者听不清

guaike:

上周才买的 iPhone 16PM ,iOS18.5 ,手机打电话、钉钉通话声音都是正常的,

和几个朋友微信电话,几乎都反馈说通话经常听不清。 大概有 10%的时间对方听我的声音不太正常,要么是刚接电话十几钟听不清,或者是通话过程中有时候突然声音失真或声音变小。

搞不懂,你们有遇到类似的情况吗? 会不会是最新版微信或者 iOS 的问题

352 空气净化器联网真是个灾难,不知道有没有 352 内部人员来认领

BryanAdams:

352 的净化器联网简直就是个灾难……各种不兼容,各种连接不上,各种服务器没反应。

打售后电话来来回回就会那几句,很抱歉给您带来不便,解决方案就是你重置一下净化器、重置一下路由器、重置一下手机、你用手机热点连一下之类的官方套话,再问深一点就要消费者拍视频,然后还要消费者用微信加一个“352 阿源”之类的账号,把视频发给他。消费者礼拜一打的电话然后申请加这个售后阿源做好友,一直到礼拜六都没通过……

再次打电话过去客服又是一顿官方套话转圈圈,大话套小话,根本不知道该怎么解决问题,消费者直接申请与客服负责人联系的时候客服才害怕自己这个月的绩效受到影响,连忙用缓兵之计安抚消费者说让本地的售后师傅上门看一眼……

没想到本地师傅也是个半懂不懂的,电话打给消费者嘴里还是官方那些套话,真把消费者当傻子一样对待,消费者跟他解析说都试过仍然无法连接,师傅就发作了,态度极差,说行吧行吧,我看一下什么时候过去看吧,还说只负责连接到自己的手机热点就算完成售后,不保证可以连接入客户家网络……那请问这样的售后消费者要来有什么用呢?师傅是打算把手机永远放在消费者家里当热点使用了吗?消费者为了一个空气净化器还需要更换整个网络系统吗?

后续消费者要求高级技术顾问提供技术支持协同 debug 帮忙解决联网问题,就开始一推二,二推三,三诈不知,只会让一些底下的话务员来来回回给您打电话来说一下客户不会联网、客户不会用 app 、客户家网络波动、之类的问题。反正绝对不是 352 家的问题,一定是客户家的问题。352 这种做派,当初买的 4 台空净+1 台加湿器就算自己认清楚 352 的学费了。

再说,就这水平还不肯开放协议加入 homeassistant ,真以为世上只有 352 了吗?我看早晚被抛弃。

再见了 352

然后我想干什么大家一定都知道了吧,市面上有么?

Footballer Thomas Partey charged with rape

Getty Images Thomas Partey in Arsenal kitGetty Images

Former Arsenal footballer Thomas Partey has been charged with five counts of rape and one count of sexual assault.

The offences are reported to have taken place between 2021-2022, the Metropolitan Police said.

The charges involve three women with two counts of rape relating to one woman, three counts of rape in connection to a second woman and one count of sexual assault linked to a third woman.

The contract of the 32-year-old footballer, from Hertfordshire, ended with Arsenal on Monday after playing with the team since 2020. BBC News has contacted the team for comment.

The charges follow an investigation by detectives, which started in February 2022 after police first received a report of rape.

Det Supt Andy Furphy, who is leading the investigation, said: "Our priority remains providing support to the women who have come forward.

"We would ask anyone who has been impacted by this case, or anyone who has information, to speak with our team. You can contact detectives about this investigation by emailing CIT@met.police.uk"

Mr Partey is expected to appear at Westminster Magistrates' Court on Tuesday 5 August.

He joined Arsenal for £45.3m from Atletico Madrid in October 2020, made 35 top-flight appearances last season and scored four goals as the London club finished second in the Premier League.

He also played 12 times in the Champions League as the Gunners reached the semi-finals before being knocked out by eventual winners Paris St-Germain.

Overall, he made 130 Premier League appearances for Mikel Arteta's side, scoring nine goals.

Kent council bans transgender books in children’s library sections

Kent County Council has removed all transgender-related books from the children's sections of its libraries

A council has removed all transgender-related books from the children's sections of its libraries, its leader has announced.

In a post on social media, Kent County Council leader Linden Kemkaran said the books were to be removed with immediate effect in a "victory for common sense in Kent".

Paul Webb, Reform UK's communities portfolio holder who oversees libraries, said the move came after a "concerned member of the public" contacted him.

The Liberal Democrat leader of the opposition, Antony Hook, said: "It is bizarre that the leader of the council is making announcements on social media, rather than to the council."

It is unknown how many books are to be removed or how the council will classify transgender-related books.

The authority runs 99 community libraries and five mobile library vans.

Defending the decision, Webb said: "In our society, children are quite rightly and properly protected from items and actions that could cause them harm – for example alcohol, cigarettes and gambling.

"My fellow Reform members and I believe that our young people should be protected from exposure to potentially harmful ideologies and beliefs such as those held by the trans lobbyists."

When the BBC asked if Reform UK had carried out an assessment to understand the impact of removing the books, Webb said: "As far as impact assessments are concerned, I would have thought that question should have been asked before these books were placed in the children's section to begin with."

Ms Kemkaran added: "Telling children they're in the wrong body is wrong and simply unacceptable."

Hook said he had written to the head of Kent library services to ask for an update on what books were to be removed.

He said: "The announcement made by Ms Kemkaran is vague. She does not specify what books she is referring to. This needs to be properly explained."

Meanwhile, Labour MP for Chatham and Aylesford Tristian Osbourne has called the decision "unedifying gender baiting of the LGBT community".

'Unsafe, unwelcome and silenced'

Steven Pullen, founder and director of Swale Pride, described the move as "deeply upsetting".

He said: "It emboldens anti-trans rhetoric and contributes to a culture where marginalised people feel unsafe, unwelcome, and silenced."

And Erin Strawbridge, the manager of the Folkestone Bookshop, an LGBTQ+ bookshop, told BBC Radio Kent: "Censorship does not stop people from learning information but it does send the message, and it's sending a message to the young people of Kent that they're not safe and they're not welcome if they're LGBT or trans.

"It just pushes kids into the closet, into worse mental health situations. It's just going to scare young people."

Discussions ongoing about new party, says Corbyn

PA Media Jeremy Corbyn and Zarah SultanaPA Media

Jeremy Corbyn has said "discussions are ongoing" after ex-Labour MP Zarah Sultana announced she was quitting the party to co-lead a new left-wing party with him.

The ex-Labour leader congratulated Sultana on her "principled decision" to leave and said he was "delighted that she will help us build a real alternative".

He said "the democratic foundations of a new kind of political party will soon take shape" but stopped short of providing details as to who would lead it.

Talks have been going on under the radar for some time to turn the small group of independent pro-Gaza MPs, co-ordinated by Corbyn, into an actual political party which could stand candidates at next year's local elections.

But the BBC has been told the question of leadership and the exact timing of the announcement had not been settled when Sultana made her declaration on Thursday evening.

Some of those behind the project wanted a democratic conference to decide the leadership question.

Some Labour MPs on the left of the party have praised Sultana but so far none has said they will be joining the new set up.

Ian Lavery, Labour MP for Blyth, told the BBC's World at One: "Perhaps she thinks she hasn't left the Labour party, but the Labour party has left her.

"People are really fed up of the two party system with regards to Labour and with regards to Conservatives."

"And I think that there is a huge appetite for a left wing alternative to the two mainstream parties."

Responding to Sultana's decision, Home Secretary Yvette Cooper said the MP had "always taken a very different view" from the Labour government on a range of issues.

Defending the government, she pointed to falling NHS waiting times, additional neighbourhood police officers and extending free school meals as examples of "real changes that have a real impact on people's lives".

Manchester Airport brawl followed assault at Starbucks, jury hears

A brawl filmed at Manchester airport last summer followed an attack on a member of the public at Starbucks, a jury has heard.

Brothers Mohammed Fahir Amaaz, 20, and Muhammad Amaad, 26, are said to have used a "high level of violence" in assaulting three police officers in Terminal 2 on July 23.

Police were at the airport responding to an earlier incident at the Starbucks cafe where Amaaz headbutted a man and punched him, Liverpool Crown Court heard. Both brothers, from Rochdale, Greater Manchester, deny the allegations.

Opening the prosecution case on Friday, Paul Greaney KC said police later traced the brothers at the terminal's car park payment area.

Three officers, PC Zachary Marsden and PC Ellie Cook - both armed - and PC Lydia Ward, unarmed, approached the defendants, he said.

Mr Greaney went on: "The officers attempted to move Mohammed Fahir Amaaz away from a payment machine in order to arrest him, but he resisted, and his brother Muhammad Amaad intervened."

He said they both assaulted PC Marsden.

"In the moments that followed, the first defendant also assaulted PC Cook and then PC Ward too, breaking her nose," Mr Greaney said.

"The defendants used a high level of violence."

Amaaz is alleged to have assaulted PC Marsden and PC Ward, causing them actual bodily harm.

He is also accused of the assault of PC Cook and the earlier assault of Abdulkareem Ismaeil at Starbucks.

Amaad, 26, is alleged to have assaulted PC Marsden, causing actual bodily harm.

Mr Greaney said the defendants had travelled to the airport with their young nephew to collect their mother who was due to arrive back on a flight from Qatar.

He said it was clear that "something happened" involving Abdulkareem Ismaeil, who was on the same flight as the pair's mother, that "made [her] unhappy".

She pointed out Mr Ismaeil, who was in Starbucks with his family, to her sons as they were walking through the terminal.

"At just after 8.20pm, the defendants entered Starbucks and confronted Abdulkareem Ismaei," Mr Greaney said.

"During that confrontation, Mohammed Fahir Amaaz delivered a headbutt to the face of Abdulkareem Ismaeil and punched him, then attempted to deliver other blows, all in front of a number of children.

"The prosecution case is that this was obviously unlawful conduct."

Mr Greaney told jurors the prosecution's position was this was "not a complicated case" as the events were captured on CCTV.

"So you will not have to depend only on the recollections of witnesses. You will also be able to see with your own eyes what happened," he said.

Mr Greaney said the defendants would say "that at all stages they were acting in lawful self-defence or in defence of the other".

"Our prediction is that you will readily conclude that the defendants were not acting in lawful self-defence and that their conduct was unlawful," he added.
