招商银行

金融街笔记20180510

晚上回到家，猛然想起来和招商银行同行，竟然有18年。

当初我发现招商银行的几个特征①真皮沙发 ②薄荷糖或大白兔 ③千平米营业网点

后来陆续发现招商银行的一些特征，家庭内转账免费收纳在校大学生和家长，客户分级，引导客户去证券开户。

后来发现一条原则 适度领先，确保第一。

18年的坚持，真心不容易。

金融街笔记20180511

经叔平，民生银行创始人，曾经担任全国工商联主席。

年轻太美好了。 年轻的时候遇到大人物，是大人物可以做的事情，我即使做不到也可以模仿。 年龄大了，遇到大人物，是大人物可以做到的事情，我压根做不到，只是想到立即臣服归顺获得一份工作。

鼓励趁年轻的时候多出去转转，增广见闻，遇到一个可以模仿的大人物。

经叔平老爷子，点亮了我的人生，让我的人生变得有意义。以前不知道该做什么，不敢想，也不知道往哪儿想。

Golang

Gin框架介绍

准备工作

  1. 确认本地环境的$GOPATH

    • Windows 下使用 echo %GOPATH%
    • Linux 下使用echo $GOPATH

  2. 获取远程包 go get github.com/gin-gonic/gin

    1
    2
    //升级安装请增加参数 -u
    go get -u github.com/gin-gonic/gin

  3. 输入go version确认本地环境的Golang版本

第一个案例程序

  1. 在您的$GOPATH目录下创建子文件夹 $GOPATH/src/gin-first
  2. 切换到上述子文件夹下创建 main.go
  3. 复制如下内容到main.go

First

  1. 创建如下文件夹 $GOPATH/src/gin-first
  2. 在上述文件夹下创建main.go
  3. 复制下面的内容到main.go
  4. 在命令行窗口中运行 go run main.go
  5. 在浏览器中打开 http://127.0.0.1:8080/ping可以看到返回内容pong

如果您使用macOS或Linux，您也可以在Shell窗口中输入如下命令

1
curl http://127.0.0.1:8080/ping

看到返回 pong

package main

import "github.com/gin-gonic/gin"

func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    r.Run() // listen and serve on 0.0.0.0:8080
}

运行

  1. 上述子文件夹下运行 go run main.go
  2. 将看到输出内容 [GIN-debug] Listening and serving HTTP on :8080
  3. 打开浏览器访问 http://127.0.0.1:8080/ping 可以看到返回pong
Golang

Dockerfile for Alpine+Golang

在开发环境，测试环境下使用 Golang 的 Docker 镜像。 目前使用两个Dockerfile，一个基于Alpine，一个基于CentOS。

使用时请注意修改掉私人有关的内容,

  • 比如依赖的私人文件，您在docker build时找不到
  • 私人的Github授权文件

在Dockerfile中完成如下几类动作

  1. 下载或更新到最新版本的的Golang，目前版本式1.12.3
  2. 设置时区到东八区
  3. 设置Golang所依赖的环境变量比如 GO15VENDOREXPERIMENT GO111MODULE GOROOT GOPATH
  4. 配置访问Github的ssh
  5. 设置工作目录 WORKDIR $GOPATH/src
  6. 声明VOLUME ["/data/yourcorp"]
  7. 声明开放端口EXPOSE

Dockerfile for Alpine+Golang

特别注意本Dockerfile中直接从Golang官网下载最新版本，某些地区可能需要科学上网。

金融街笔记20180525

建国初年，毛泽东曾对黄炎培说：在中国近代历史上，有4个人是我们万万不可忘记的，他们是：搞重工业的张之洞；搞纺织工业的张謇；搞交通运输业的卢作孚；搞化学工业的范旭东。这其中的卢作孚跨越了”革命救国”、”教育救国”、”实业救国”三大领域，并且在几个方面都各有成就。

十六七岁读卢作孚传 ①他开通长江上游轮船航运，运送川中物资出川。 ②抗日内迁他支持常公从武汉搬运机械设备军火上送到重庆，自备柴油。 ③缙云山豆花饭宴请常公，暗示蜀中百姓疾苦。 ④办学支持科学事业。

牌照经济学

金融街笔记20180524

最重要的事情

  • 牌照经济学
  • 牌照经济学
  • 牌照经济学

下面还有三万句废话，我懒得敲出来。套用曾经混BBS的一句套话，本文正文如题，其他都是废话。

Golang

Windows下编译Golang

建议维持如下目录结构

1
2
3
foo -->src
    -->bin
    -->pkg

编译过程一般来说分成如下几步

  1. 前从 git/svn 服务器抓取最新的版本

  2. 清理现场

  3. 获得时间戳，以便在后续编译过程中带入作为版本号的后缀

  4. 编译，携带若干参数（资源文件、不含调试信息、版本号，目标文件名称）

  5. 复制到特定文件夹

  6. 连同配置文件一起压缩，压缩文件带有上述时间戳

  7. 导出源代码，并压缩，压缩文件带有上述时间戳

  8. 清理现场

上述步骤连续做下来，没有一个工程师可以可以连续无差错做两遍。 这样的场景适合创建一个批处理文件，如果在Linux下的话就是Shell脚本文件。

下面是一个批处理文件的示例，请参阅。

@echo off
echo 编译打包命令如下
echo ==========================================
set /a t1=(1%time:~0,2%-100)*1
if %t1% LSS 10 set t1=0%t1%
set ymd_hm=%date:~0,4%%date:~5,2%%date:~8,2%%t1%%time:~3,2%%time:~6,2%
set "Version=v2.2.%ymd_hm%"
echo 版本号: %Version%
@echo on
go clean
go build -o YOUR_PROGRAMNAME.exe -ldflags "-s -w -X main._VERSION_ '%Version%'"
set PATH=%PATH%;C:\Program Files\WinRAR;
copy YOUR_PROGRAMNAME.exe "YOUR_PROGRAMNAME_v%ymd_hm%.exe"
rar a "YOUR_PROGRAMNAME_v%ymd_hm%.ra_" "YOUR_PROGRAMNAME_v%ymd_hm%.exe"
@echo off
echo ==========================================
@echo on

如果要支持上述代码中的，在编译命令中引入版本号，那么需要在源代码文件， 即包含 main 方法的 go 文件中包含如下变量定义。

1
2
3

//如下变量供编译器使用，不适用于golint的修改建议
var _VERSION_ = "unknown"

BTW

  1. golint 认为上述变量命名不符合规范，请忽略之

  2. 关于 Windows下批处理文件的更多知识，请 google 之

陈春花的故事

金融街笔记20180611

一四年冬天拜访一家八线城市郊区的冷库。

冷库的老板告诉我刚刚被新希望收购，考虑我可能不知道新希望，告诉我一家做饲料的公司。

我知道新希望，也知道陈到这家公司做客卿。

这家冷库从表面上看地处八线城市郊区，老板水平冷库面积，都没什么可圈可点之处。

但是仔细琢磨冷库这个案例，

  1. 地处三省交界，发达的公路网络可以冷链触达周边五省（冷链有距离限制）
  2. 老板做事情精致有追求皮鞋干净办公室整洁，苹果一体机
  3. 老板积极拥抱变化尝试粗糙的供应链金融
  4. 老板节制，老板回民经营冷库只接纳民族习惯认可的肉类，这需要多大的勇气。

自此对陈春花刮目相看。
