A bit surprised to see there is no mention of Liquibase, Flyway or others. Not to mention there is also "https://www.dolthub.com/". This was just for git.
I work for the company that owns/developers Flyway, so I didn't include it in here.
However, for DBAs, they often are doing ad hoc stuff and there is a bit of overhead for FW/LB that they may not want. This is part of a series, just getting people comfortable with tracking their work.
Another thing I had experienced before was a document picture I used after downsizing to mandatory upload size had a character/number randomly changed (6 to b or d). Don't remember which exactly and had to convert the doc to PDF that managed it better.
> investigating dice rolling patterns
A friend showed me a dice rolling game where you roll a bunch of dice and add up the values. I mentioned that if you roll enough dice and add up all the values, at some point it gets a lot less “random”.
And result turned out "true"? Rolled a die for 2500 times and the sum is all around 8500! I wonder what would be the results for 25/250 times? So, this is sum(expectations).. and for rolling a die, it is 3.5 [(1+2+3+4+5+6)/6 => 21/6], so the answer was 3.5 x 2500 = 8750. Should hold good for all numbers relatively large.
This is a classic illustration of the Central Limit Theorem--in fact, the example is even on the Wikipedia page [0]. The distribution tends towards a normal distribution as n increases (though to actually take the limit you need to rescale).
I am confused how this works. I would assume `SECONDS` would just be a shell variable and it was first assigned `0` and then it should stay same, why did it keep counting the seconds?
> SECONDS
bash: SECONDS: command not found
> SECONDS=0; sleep 5; echo $SECONDS;
5
> echo "Your command completed after $SECONDS seconds";
Your command completed after 41 seconds
> echo "Your command completed after $SECONDS seconds";
Your command completed after 51 seconds
> echo "Your command completed after $SECONDS seconds";
Your command completed after 53 seconds
> Trias shared one story that karate had been born in a monastery in China, where a wandering Indian master named Bodhidharma noticed that sedentary monks were growing sickly and devised the martial art to cultivate their strength.
Interesting to see there is no mention of "kalaripayattu". Kalari as its famously shorten [1] have about 2000 years of history and is used with both weapons and no-weapons. Bodhidharma was said to have left from then Tamil states to China.
Leaders work every day to create a safer, more productive, higher performing, more diverse, and more just work environment. They lead with empathy, have fun at work, and make it easy for others to have fun. Leaders ask themselves: Are my fellow employees growing? Are they empowered? Are they ready for what's next? Leaders have a vision for and commitment to their employees' personal success, whether that be at Amazon or elsewhere.
Success and Scale Bring Broad Responsibility
We started in a garage, but we're not there anymore. We are big, we impact the world, and we are far from perfect. We must be humble and thoughtful about even the secondary effects of our actions. Our local communities, planet, and future generations need us to be better every day. We must begin each day with a determination to make better, do better, and be better for our customers, our employees, our partners, and the world at large. And we must end every day knowing we can do even more tomorrow. Leaders create more than they consume and always leave things better than how they found them.
That said, these are not objectives. They are more like vision statements. I assume goals a measures are derived off of these and updated over time.
Most principles are, no? They have goals and KPIs and reports and what not, these are the leadership principles. One would hope they revise their numbers as well to reflect these principles and correct for unintended consequences.
John Conway loss will live in my memory for sometime, just like loosing John Nash on a car accident. Their contribution to math will outlive everything else.
