Reading Time: 2 minutes Our 10 year old got sick on the 1st day of Labor Day weekend – 8/31 Saturday. She has violin private lesson and we had to do it over the Zoom. Initially we didn’t think too much of it, but on Monday 9/2, as we didn’t see her getting any better we decided to go
Reading Time: 2 minutes This probably should be the series 2 of Ladue high school, we are coming, series I is here and I wrote it about 9 months ago. Now it’s real – which means, every morning, I have to be patient about the traffic on Warson road. And I am very proud to announce: so far I
Reading Time: 2 minutes Recently due to the booming of AI, the daring of AI and the wall street Nvidia $NVDA had crazy good earning reports in last year or two (20 months to be exact, if we look at the stock chart from Jan 1st, 2023).

Reading Time: 2 minutes T-Mobile I think I started using T-Mobile probably from year 2012, ever since my 2-year contract with AT&T ended. I got the 2-year contract when I bought iPhone 4 at the Apple Store in fall 2010. H2O Note with T-Mobile, I did not sign up the data plan. And In year 2014, I started looking
Reading Time: < 1 minute I normally don’t bet on earnings (earning report), but when I do, I usually lose. –yours truly And $PDD was no exception. Yesterday 08/26/2024 Monday morning, before market open, I noticed the stock was free falling. Note I bought 6 shares before the earning report. And basically this confirms another thing I talked from time
Reading Time: 5 minutes I am not 100% sure how much the below section is applicable to the kids in the Ladue School nowadays.

芝加哥到香港的直达航班 在小红书上听到这个，跑到她家网站一看，果然有 ORD to HKG 航班，价格也还公道。看来美国的航空公司短期内是不会开通 ORD to PVG 的航线了。 It looks like this flight started on October 3, 2023.

Reading Time: < 1 minute 再说说software rewrite：我在上班的地方，参加过两次rewrite （重写）的项目，现在的项目是其中一个，大概做了两年多了：中间换了不知道多少contractors，现在好像还没有看到the light at the end of the tunnels。每次此类项目，management 一开始都有非常optimistic 的expectations：但实际工作中不是这样。 Why rewrite is hard?
