Two years ago, I made my first DIY curb ramp. See here. It worked well. Until now, I had that one and another one I made from concrete mix which is really heavy (> 35 lbs). I am tired of lifting it back and forth whenever I need to use it. So I decided to make another wooden one to make a set. In this video, you’ll see entire process of my making it; some portion were sped up 10x to avoid the boredom of repetitions. Hope you enjoy it. It was fun to be doing this in the pleasant weather of 70F under the sun.

San Francisco The Beautiful – A 2-Day Trip
The family took a trip to San Francisco and stayed near Fisherman Wharf. In addition to the Fisherman Wharf, we visited the Burger Bar in front of the Union Square, Boudin Museum, Golden Gate Bridge, Colorful Steps, and Ring Mountain Open Space near Corte Madera.
Book Review: “Things A Little Bird Told Me” by Biz Stone
This book is a short memoir of Biz Stone, who stumbled on the idea of Twitter while researching new things to make when odeo, the podcasting startup, wasn’t doing so good. He teamed up with his coworker, Jack, to start a simple text message system where connect people can see the messages in real time. The 140-character limitation came from the text message system (160 characters).
During his high school years, he was too exhausted from attending school and working to help out his single-mom family. He negotiated with the teachers to not doing any homework and still maintain reasonable grades. Now that takes guts!
Until the Twitter success, he was constantly in debts especially after his initial start up company failed. He landed at Google doing blogging and eventually left that post to join Odeo.
The rest of the book he talked about the lessons he learned:
A short lesson on constraint: “Embrace your constraints, whether they are creative, physical, economic, or self-imposed. They are provocative. They are challenging. They wake you up. They make you more creative. They make you better.” The constraint of 2-week hackathon led to the creation of Twitter. 140-character tweet is in itself a constraint to force creativity.
Twitter is successful because of the flocking behavior as in birds as he observed when Twitter was introduced to the Southwest Interactive Conference (SXSW). That’s when Biz realized that Twitter is going to be a success.
Be willing to fail in order to be successful is one of the advises Stone gave with his example of learning and executing back handspring in high school.
Compartmentize the software modules allows Twitter to become more stable – a lesson from the Star Trek. This same philosophy should apply to every undertaking in life. Modularize if possible. Don’t open up to developers too quickly, lest suffers the stability issue Twitter faced in its early days.
Stone was asked to be the “bright spot” of the company when their system crashed. “An open, curious, optimistic mind yields solutions, and has a better time along the way.”
Twitter almost got bought up by Facebook back in 2008. He came up with a huge figure $500M for the company. And Mark Zuckerberg went for it. This was an interesting story.
The new rules for Twitter employees:
1. We don’t always know what’s going to happen – humility.
2. There are more smart people out there than in here – don’t always look internally for answers.
3. We will win if we do the right thing for our users – sometimes conflicts with profit.
4. The only deal worth doing is a win-win deal.
5. Our coworkers are smart and they have good intentions.
6. We can build a business, change the world, and have fun.
The 25-dollar in a gift card from DonorsChoose.org goes a long way in choosing who you donate the money too. What a clever idea.
This is a fun book to read. You probably won’t learn too much but it’s good to know how you can stumble into a “billion”-dollar idea given a short deadline while fighting to survive. Biz Stone is a smart and lucky man.
Book Review: “Killing Patton” by Bill O’Reilly & Martin Dugard
This is a fascinating story of the World War II era centering around George Patton, a 4-star general leading the 3rd army in driving Adolf Hitler to his demise. It’s as much about the key characters in WWII as about George Patton’s life.
From this book, I learned about several interesting tidbits about all the key players in World War II.
Franklin Roosevelt: He’s a man of great passion for the country who worked himself to death. But his personal life like most political figures in the early era is bit shady.
Dwight Eisenhower – a military man with political savvy that frequently ran into conflict with George Patton in his effort to appease the British by favoring UK’s Montgomery at times to make UK look good. Also, some mention of his affair was intriguing.
Winston Churchill – tried hard to position UK’s power post WWII by working out deals with Russia’s Stalin, who didn’t honor any of them. He was voted out of office at the end of WWII but came back to power later. Pretty resilient. The fact that Churchill was more American than British; his mother was from NY.
Joseph Stalin – what a vicious dictator he was in treating his people and his German enemy. He was conniving, calculating leader. No wonder Patton was very skeptical of the Russians and fearful of the Russians more than the Germans.
My impression of George Patton:
1. He appears to be a very good judge of characters like Stalin, Hitler, and Dwight Eisenhower.
2. Patton made lots of enemy and got himself into controversies by talking from his guts, especially the last controversy he talked something nice about the Germans and his distrust against the Russian. Almost got himself fired.
3. Some personal poor judgement on his affair with young Lucy Mercer Rutherford and sending a commando to rescue his son-in-law in keeping his promise with his daughter. The poorly executed plan cost more than 30 lives.
4. His cause of death appears to be non-accidental. Looked like someone was out to get him. That’s what happened when you had lots of enemy. My guess is the OSS (Office of Strategic Services) head, William J. Donovan.
5. Patton was a very brave man and served the country well despite the strange death shrouded his latter day in life. Was it an accident or assassination? The author presented the facts that tilted toward the latter.
This is a great book. Not only the Patton character is interesting, the surrounding characters and the war details in the book were equally intriguing. I highly recommend this book, even if you’re not a history buff. It reads like a novel and very educational.
Maker Faire 2015, San Mateo
Megabot at Maker Faire
Visited the Maker Faire and video recorded this Megabot’s shooting a paint ball into a car. It’a an amazing feat to build a robot like what we see in movies and video game. Hope you enjoy it!
How I Upgraded My Laptop Harddisk to SSD
The best ways to boost your computer performance without changing the CPU are two folds: 1. Increase your DRAM or DIMM/memory capacity, which serves as a local scratch pads for your operating system and applications. 2. Increase your harddisk speed by changing to SSD (Solid-State Drive or Flash Drive). In this video, I showed you how I upgraded a cheap laptop (~$250) to an Ultrabook by replacing the slow harddisk to an SSD. This laptop already has 4GB of memory and is plenty enough. All it needs is a fast SSD to turn into a reasonably fast computer with a long battery life (> 6 hrs).
