Reading Time: < 1 minute Or version control. My wife is taking a class at launchcode and she just started learn git, one of the most popular source code control systems. Git has a steep learn curve, in my opinion, but it’s getting popular, widely used and I think that’s the reason they picked it. But I think that could

Reading Time: < 1 minute 今晚在高中群里突然听到我的初中班主任数学老师，省劳动模范周国夫三年前已去世。下面的博客中有周老师的照片。我从初中到镇海中学住宿读书，一个月回一次家，从某种意义上讲，周老师就是我们这些住宿生的父亲。我也受到周老师很多影响，尤其是学习（自学）方法和态度方面。他的数学课布置很多讲义（作业），他会讲解一些题，但主要是要自学。记得我们初一自学初二内容，以此类推。他有时又很大方，比如说数学课以后是英语考试，他说你们看英语吧。刚到镇中不久，有一次我发烧，有点严重，他和一些同学带我上医院，忙前忙后。现在想起来就像我对我的小孩一样。 这里有一个关于周老师的简短介绍。

Reading Time: < 1 minute 这可能是我写博客以来隔得最久的两篇相关文章。我说美国大选: I在这里。时隔八年，从上一次Obama”Yes We Can”到这一次Trump”Make America Great Again”. 从Google Search Engine Optimization（打败希拉里的主要原因之一，当时Facebook只是起步阶段）到这次Trump基本上垄断Twitter(参考1和2）。引用第一篇文章的一句话： But if the presidential election was a Twitter popularity contest—and thank God it’s not—one thing is clear: Trump would win by a landslide. 其实Internet和Web从2004年就被采用，当年HOWARD DEAN用的Tool是Meetup,这个网站有点不温不火，现在还是一个IT User Group常用的聚会工具。 这一次Trump居然赢了。其实我认为核心原因还是美国选民思变，奥巴马8年执政，在很多方面推行过于Liberal的政策，比如说这个学校LGBT学生上哪个厕所，他老人家（他手下的教育部的人）要公立学校允许LGBT学生挑选她／他们认为合适的厕所。这个事引起很大反响／反感。当然还有经济上的原因。这十几年，说实话，中产阶级，尤其是蓝领，工作被外包，日子江河日下。这个是关键（从小布什到奥巴马）。新媒体有影响，但应该是次要的。

Reading Time: < 1 minute (01-31-2019 Update) So I got 2 more years out of the MacBook after the fix. Actually last year (March 2018) I made another mistake, I leaked water (water bottle leak) to the MacBook when I put it in a sports duffel. So had to go to Apple store to get it fixed again (I think

Pre-requisite: vagrant How I created a Vagrant instance on mac (or be more precise, Vagrant Cluster (github)). Note I installed the Virtual Box,

Reading Time: < 1 minute Why I am saying that? I am the only active person among my “Fitbit friends”. So I assume it could means a few things: 1) All my friends stopped wearing Fitbit; 2) All my friends did not sync (or their Fitbit could not sync, which I admit is a real problem for Fitbit); 3) All

Reading Time: < 1 minute Serenity started 1st grade this fall. Same school. I have some ideas on first grade, mostly around the homework, “more serious school” vs. the kindergarten which has more play time. I learned from fellow parents last year when they talked about it after MFS (I volunteered there). Seeing is believing. Serenity now has been in

Reading Time: 3 minutes I first learned the “production environment” in 2010, when I worked as contractor for a major railway company. Before that I was mostly in CAD software development and consulting environment the word “production” did not come often. To be precise at Siemens PLM/UGS as developers, we did have access to various production releases and did
