网络感觉很一般。SSD是三星的850PRO,但是通电时间已经达到了6万小时了。

常用软件windows离线安装包

现在很多软件都搞在线安装,实际上不适应天朝用户,下面收集几个离线安装包下载路径:

dropbox
https://www.dropbox.com/download?full=1&plat=win

chrome
https://www.google.com/intl/en/chrome/?standalone=1

firefox
https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

firefox esr
https://www.mozilla.org/en-US/firefox/enterprise/#download

全面转向FireFox

一直以来桌面浏览器使用的都是Chrome,虽然没什么问题,但是Chrome的一些特性让我很不舒服,比如强制升级,随意删减功能,搞一些狐狸花哨的没用的东西,这些都是可以忍受的,毕竟我比较依赖Google的各种服务。直到有一天我发现笔记本电脑CPU狂转,打开任务管理器发现是Chrome的software_reporter_tool.exe 进程扫描硬盘本地文件。以前一直用台式机没有感受到,最近一段时间经常用笔记本电脑才注意到这个事情。太恶心人了太流氓了,一个浏览器软件凭什么扫描硬盘呢?计划未来一个礼拜内全面切换到firefox esr。我现在终于理解为什么ubuntu自带的浏览器是firefox,而不是chrome。

换了新的本本ThinkPad X13

人到中年,已经背不动ThinkPad T480了,以前觉得T480的双电池桥接技术很牛逼,现在只觉得太重了太累了😔

最近换了ThinkPad X13 AMD 08CD,这个笔记本用了两天,我非常满意,各方面都比T480强太多了,重量只有不到1.3kg,背起来很轻,指纹识别速度比T480提高了一大截,准确率也大大提高,CPU性能吊打intel,风扇非常安静,屏幕素质高,三星PM981a这个NVME SSD也让我很快乐,唯一让我纠结的就是这个R5 4650U的CPU了,下次直接上R7吧,就不用纠结了。

还有最近开始不喜欢干买本本回来拆开后盖这种事情了,感觉太吊丝了, T480的后盖拆开来以后会有一条缝让我很不舒服,不再像刚出厂时那样严丝合缝了,而且很容易搞坏卡扣,像X13买回来啥都不用升级感觉很方便。现在觉得每年换一个笔记本很有必要,各方位的用户体验的提升让人非常愉快。

关闭ipv6

最近感觉电脑网络很卡,今天早上起来特别卡,但是手机网络不卡。思考了一下,应该是因为最近买的华硕路由器里面打开了ipv6,而现在的premium route都是ipv4的,在路由器里面把ipv6关了就不卡了,顺便在windows10里面把ipv6也关闭了。

Thinkpad T480升级AX200

T480原厂自带的WIFI 蓝牙芯片是Intel的8265NGW,最近换了WIFI6路由器,然后把T480的WIFI芯片也升级一下,淘宝上只要50块钱就能买到AX200芯片。换了以后发现蓝牙鼠标掉线断流的问题似乎解决了。芯片换了以后WIN10系统需要重装驱动,ubuntu 20.04免驱动。太好了!

更新:还是会断,但是似乎比以前断的概率小一些了。老老实实用unifying吧。

aff研究新技术还是很有意义的

最近开发了新的aff相关的技术,也尝试换了新的服务商,感觉工作效率比以前提高了很多,这一切都是非常有意义的。不过对于aff而言要注意控制研究新技术的时间比例,对于aff而言,大部分时间还是应该花在研究流量上面。
