巴菲特致股东信-1980年

 笔记： 会计中对于下属股权公司的记账方式有3种： 持股50%以上，全部并入 持续20%--50%，则按持股比例并入 持股20%以下，则以实际收到的利润返还，计入报表 这种会计方式，会导致伯克希尔旗下，不少的企业，未能暴露实际的收益情况 对伯克希尔而言，对盈余的认定并非取决于持股比例是100%，50%，20%，5%或是1%，盈余的真正价值在于其将来再投资所能产生的效益 我们宁愿将所赚的盈余继续交由不受我们控制的人好好发挥，也不希望转由我们自己来浪费 高通货膨胀等于是对投入的资本额外课了一次税 翻译： https://xueqiu.com/6217262310/131837878 https://archive.ph/XMX5n  原文： Buffett’s Letters To Berkshire Shareholders 1980 巴菲特致股东的信 1980 年 Operating earnings improved to $41.9 million in 1980 from $36.0 million in 1979, but return on beginning equity capital (with securities valued at cost) fell to 17.8% from 18.6%. We believe the latter yardstick to be the most appropriate measure of single-year managerial economic performance. Informed use of that yardstick, however, requires an understanding of many factors, including accounting policies, historical ca...

黑客讲述渗透Hacking Team全过程

原文地址在 Freebuf ，后来已经被删除 Wayback Machine 备份 近期，黑客 Phineas Fisher在pastebin.com上讲述了入侵Hacking Team的过程，以下为其讲述的原文情况，文中附带有相关文档、工具及网站的链接，请在安全环境下进行打开，并合理合法使用。作者部分思想较为激进，也请以辩证的观点看待之。 1、序言 在这里，可能你会注意到相比于前面的一个版本，这个版本的内容及语言有了一些变化，因为这将是最后一个版本了 ［1］ 。对于黑客技术，英语世界中已经有了许多书籍，讲座，指南以及关于黑客攻击的知识。在那个世界，有许多黑客比我优秀，但他们埋没了他们的天赋，而为所谓的“防护”服务商（如Hacking Team之流的），情报机构服务工作。黑客文化作为一项非主流文化诞生于美国，但它现在只保留了它本质的魅力，其他均被同化了。从黑客的本质出发，至少他们可以穿着一件T恤，把头发染成蓝色，用自己的黑客的名字，随意 洒脱 地做着自己喜欢的事件，而当他们为别人（前文所指的 Hacking Team及情报机构 ）工作的时候，会感觉自己像个反抗者。 如果按照传统的方式，你不得不潜入办公室偷偷拿到文件［2］，或者你不得不持枪抢劫银行。但现在你仅仅需要一台笔记本，躺在床上动动手指便可做得这一切［3］［4］。像CNT在入侵伽玛集团（Gamma Group）之后说的，“让我们以一种新的斗争方式向前迈进吧”［5］。 [ 1 ] http: / /pastebin.com/raw .php?i=cRYvK4jb [ 2 ] https: / /en.wikipedia.org/wiki /Citizens%27_Commission_to_Investigate_the_FBI [3] http:/ /www.aljazeera.com/news /2015/ 09/algerian-hacker-hero-hoodlum- 15092108 3914167 .html [ 4 ] https: / /securelist.com/files /2015/ 02 /Carbanak_APT_eng.pdf  [ 5 ] http: / /madrid.cnt.es/noticia /consideraci...

360T7 刷机步骤及固件

https://cmi.hanwckf.top/p/360t7-firmware/   360T7的固件支持由immortalwrt-mt798x项目提供支持，请参考： https://cmi.hanwckf.top/p/immortalwrt-mt798x https://github.com/hanwckf/immortalwrt-mt798x 刷机步骤 参考 此处 的办法开启原厂固件的UART和telnet功能 在以下链接下载360T7测试固件（纯净版，无任何插件） https://wwd.lanzout.com/b0bt9idwd 密码:ezex （此固件已过时，请选择其它更新的固件） 接下来将刷入修改版uboot。修改版uboot的优点有： 固件分区可达108MB，原厂uboot只能使用36M 自带一个简单的webui恢复页面 到以下仓库的Release页面下载uboot，目前暂时仅支持360T7，后续将支持更多mt798x路由器。 推荐使用 mt7981_360t7-fip-fixed-parts.bin ， fixed-parts 代表uboot分区表在编译期间固定，不会随着uboot环境变量变化。 https://github.com/hanwckf/bl-mt798x/releases/latest 将 mt7981_360t7-fip-fixed-parts.bin 通过HFS等方式上传到路由器，使用以下命令刷入uboot mtd write mt7981_360t7-fip-fixed-parts.bin fip 确认刷入完毕后，拔掉路由器电源。然后将电脑的IP地址设置为固定的 192.168.1.2 ，接着按住路由器的RESET按钮后通电开机，等待8s后用浏览器进入 192.168.1.1 在uboot恢复页面选择要刷入的固件。immortalwrt-mt798x目前编译两个版本的360T7固件。 建议修改版uboot直接使用 immortalwrt-mediatek-mt7981-mt7981-360-t7-108M-squashfs-factory.bin ，两种固件区别如下： mt7981-360-t7-108M 为108M固件分区，原厂uboot不可启动，需要修改版u...

SS机场常用服务器线路微普及

原文link：https://www.duyaoss.com/archives/57/   为何写这么个帖子？ 更新时间：2019-11-29 由于机场用户增多，很多新用户压根不懂节点上面的名字代表什么，也不知道什么服务器比较适合自己，不懂什么是原生，等等。 所以开一个小帖，稍微介绍一下比较常见的服务器， 专业知识有限，所以只是给小白们介绍一下，其实我也很白，各位大佬见笑了。 在这里尤其感谢 Sukka 苏卡卡大佬和喵酱指导，以及 Nexitally 佩奇提供的资料介绍，否则我真不知道从哪儿开始动笔。后面地区内容都是佩奇帮忙码出来的。时间有限，慢慢再继续填充和修整 本文仅仅是抛砖引玉写一些机场主们告知我的 ISP、IDC 的体验，仅供参考。网络环境每天都在变化，今天飞快的服务器明天有可能龟速，有写的不对或者过时的地方还望大家指正。所以本文也算是一些机场主们把曾经踩过的坑分享给大家吧。（本来是想给小白写服务器介绍的，佩奇大佬写着写着就专业惯性的转到了商家哈哈哈，这是一个悲伤的故事） 测速图 Telegram 频道： https://t.me/DuyaoSS 主用链接： DuyaoSS - 毒药机场简介博客 常见名词： IPLC: "International Private Leased Circuit"的缩写，即“国际专线”。不过大部分机场通常看到的iplc，都只是阿里的经典网络，跨数据中心内网互通，阿里内网，并不是严格意义的iplc专线；当然也有其他渠道的，或真iplc，不过比较少。阿里云的内网互通底层原理是通过采购多个点对点的iplc专线，来连接各个数据中心，从而把各个数据中心纳入到自己的一套内网里面来。这样做有两个好处，其一是iplc链路上的带宽独享，完全不受公网波动影响，其二是过境的时候不需要经过GFW，确保了数据安全且不受外界各种因素干扰。但是需要注意一下阿里云的iplc也是有带宽上限的，如果过多的人同时挤到同一条专线上，峰值带宽超过专线的上限的话也同样会造成网络不稳定。其他渠道购买到的iplc价格很高，阿里云内网这种性价比超高这种好东西且用且珍惜。 IEPL国际以太网专线（International Ethernet Private Line,简称IEPL)，构建于MSTP设备平台上...

Interview at the All Things Digital D5 Conference, Steve and Bill Gates spoke with journalists Kara Swisher and Walt Mossberg onstage in May 2007.

Kara Swisher: The first question I was interested in asking is what you think each has contributed to the computer and technology industry— starting with you, Steve, for Bill, and vice versa. Steve Jobs: Well, Bill built the first software company in the industry. And I think he built the first software company before anybody really in our industry knew what a software company was, except for these guys. And that was huge. That was really huge. And the business model that they ended up pursuing turned out to be the one that worked really well for the industry. I think the biggest thing was, Bill was really focused on software before almost anybody else had a clue that it was really the software that— KS: Was important? SJ: That’s what I see. I mean, a lot of other things you could say, but that’s the high-order bit. And I think building a company’s really hard, and it requires your greatest persuasive abilities to hire the best ...

Albert Einstein Said Death Is Not An End Can Prompt You To Find The Meaning and Purpose Of Your Life

原文Link： https://quotationize.com/albert-einstein-said-death-not-end/ 产品随想注： 爱因斯坦对于死亡的观点，深深影响了乔布斯  ---------------- Albert Einstein said death is not an end if we can live on in our children and the younger generation is a line taken from the letter which he wrote to the widow of physicist Heike Kamerlingh Onnes in 1926. Besides death, he also talked about afterlife, immortality and soul. If you have read through my authentic collection of Albert Einstein thoughts on God and religion , you would know that he rejected the formal, dogmatic religion. Einstein did not believe in immortality of the individual. According to him, there is no such thing as, punishment for misdeeds or rewards for good behavior in any afterlife. For him, the so-called Theosophy and Spiritualism, was no more than a symptom of weakness and confusion. As Einstein explained that since our inner experiences consist of reproductions, and combinations of sensory impressions, the concept of a soul with...

A Sister’s Eulogy for Steve Jobs

I grew up as an only child, with a single mother. Because we were poor and because I knew my father had emigrated from Syria, I imagined he looked like Omar Sharif. I hoped he would be rich and kind and would come into our lives (and our not yet furnished apartment) and help us. Later, after I’d met my father, I tried to believe he’d changed his number and left no forwarding address because he was an idealistic revolutionary, plotting a new world for the Arab people. Even as a feminist, my whole life I’d been waiting for a man to love, who could love me. For decades, I’d thought that man would be my father. When I was 25, I met that man and he was my brother. By then, I lived in New York, where I was trying to write my first novel. I had a job at a small magazine in an office the size of a closet, with three other aspiring writers. When one day a lawyer called me — me, the middle-class girl from California who hassled the boss to buy us health insurance — and said his cl...

Interview with Steve Jobs, WGBH, 1990

Interviewer: what is it about this machine? Why is this machine so interesting? Why has it been so influential? Jobs: Ah ahm, I'll give you my point of view on it. I remember reading a magazine article a long time ago ah when I was ah twelve years ago maybe, in I think it was Scientific American . I'm not sure. And the article ahm proposed to measure the efficiency of locomotion for ah lots of species on planet earth to see which species was the most efficient at getting from point A to point B. Ah and they measured the kilocalories that each one expended. So ah they ranked them all and I remember that ahm...ah the Condor, Condor was the most efficient at [CLEARS THROAT] getting from point A to point B. And humankind, the crown of creation came in with a rather unimpressive showing about a third of the way down...
