plugin hybrid

最近搞了辆honda clarity, plugin hybrid car。Lease三年。down pament 3000,买了600的保养,每月三百二十几。

电费基本省了。公司全给付了。过桥以后可以走carpool,只用交一半过桥费。

开了clarity后就不想回头开油车了。又平稳又安静又经济。堵车的时候不耗油。刹车或者不踩油门的时候反向充电。感觉效率确实比油车高。

这个礼拜五天大概冲了45Kwh的电,跑了两百mile。加州电费19 cents/kwh。所以$8.5跑了200mile。

以前每天开odessey上下班,大概20mpg。200mile差不多要花30 ~ 40块。

所以从效率上来说,电车确实要高一些。但是电车要贵一些,折旧费也高一些。

不过政府有7500的补贴。这样消费者还是能省钱,就有动力去买电车。

Jesus Heals a Man Born Blind

// 今天要讲这个故事,又没有teachers guide,准备一下

1. He spend days sitting outdoors begging for money.

life is suffering. A blind person cannot see, cannot work, and can only beg to survive.

2. when Jesus’ disciples saw the blind man, they asked, "Jesus, whose fault is it that this man was born blind?"

life is even more suffering when get judged by other people.

People’s logic: "born blind" -> "he or his family must have sinned"

This is true in today’s world. When someone is unlucky, or lived miserably, we tend to judge them: he/she must did something bad. He/she is a loser.

We tend to be distant from these people to avoid sharing their life burden.

However, Jesus didn’t.

3. Jesus answered, "It’s not anyone’s fault. But it is an opportunity for God to show what He can do".

God’s judgement is different.

When Jesus is nailed on cross, he didn’t blame anyone. instead, he said, "they don’t know what they do".

So, never blame, take the responsibility. Or, take the opportunity.

Another story, "A Woman Caught in Adultery". Jesus said: “All right, but let the one who has never sinned throw the first stone!”

So, in God’s view, everyone is sinned, no one is better than the other.

People tend to judge other people to show self-righteousness. This is a sin by itself. It shows people replace God with himself. It’s the result of eating the forbidden fruit, i.e. the fruit of knowledge of good and evil.

An even worse consequence of "human judgement" is that people use the human standards to judge themselves. We feel shamed when we are in-competent. We might also feel worthless, no hope, guilty.

So, "human judgement" is a path to death.

4. Jesus saved the blind man.

Jesus is compassionate. Jesus regard a person’s suffering as an opportunity to show God’s grace, to show God’s love almighty power.

It’s Christian’s responsibility/opportunity to help those in need.

5. The blind man listened to Jesus and obeyed. He walked to the pool and washed his eyes. Then he could see for the first time in his whole life. He jumped for joy and shouted, "I can see!, I can see!". Then he ran to see his family for the very first time.

God show his grace to everyone. But to be really saved, we need to take the action to accept the gift. This is not as easy as it sounds to be. It requires: 1) listen, 2) obey, 3) take action. Just see what our children’s reaction to parents/teachers commands then you know how hard it is. Moreover, it requires faith in God, which happens between 1) and 2). How can you believe those "simple actions" can cure you? Without faith, you are not able to do 2) and 3).

6. The blind man do witness, shared the gospel.

The story is not end. A saved person has the responsibility to share his own story so more people can believe in Jesus and be saved.

7. Religious leader do not believe.

Even they knew the blind man, even many people confirmed the fact. They don’t want to believe. Their heart is hard. They have high social status, high intellect, and not willing to admit Jesus, a "normal" people has more power. Again, this shows how hard for a proud person to believe in God.

judgement

judgement is an essential thing

without it, we can not move or can only do random move

think about AlphaGo. For each state (config of the current board), it needs to evaluate the goodness or badness and give it a score. This is judgement.

The major difference between professional players and amateur players is the quality of their judgement system.

So, we need judgement.

But, judgement are not equal.

According to bible, there’s two judgement system, people’s judgement system and God’s judgement system.

1 Samuel 16:7: But the LORD said to Samuel, "Don’t judge by his appearance or height, for I have rejected him. The LORD doesn’t see things the way you see them. People judge by outward appearance, but the LORD looks at the heart."

We choose judgement system, other people choose judgement system and God has his own judgement system.

If we choose people’s judgement system, we choose hell to live in.

How we judge determine how we satisfy ourselves.

And things valuable in people’s judgement system is fragile and transient. It like grass quickly fade away.

But things valuable in God’s judgement system is everlasting.

1 Corinthians 13:13: Three things will last forever–faith, hope, and love–and the greatest of these is love.

So, God judge’s people by whether they have love in their heart.

But the spiritual person is able to judge all things. Yet no one can judge him. The Scripture says: “Who has known the mind of the Lord? Who has been able to teach him?” Isaiah 40:13 But we have the mind of Christ.
1 Corinthians 2:15‭-‬16 ICB
https://bible.com/bible/1359/1co.2.15-16.ICB

A person live with God’s judgement system has trascent this world and thus no one can judge him. Or, in other words, no one can hurt him by judgement.

“Anyone who listens to my teaching and follows it is wise, like a person who builds a house on solid rock. Though the rain comes in torrents and the floodwaters rise and the winds beat against that house, it won’t collapse because it is built on bedrock. But anyone who hears my teaching and doesn’t obey it is foolish, like a person who builds a house on sand. When the rains and floods come and the winds beat against that house, it will collapse with a mighty crash.”
Matthew 7:24‭-‬27 NLT
https://bible.com/bible/116/mat.7.24-27.NLT

What are you boasting about?

As a result, no one can ever boast in the presence of God.
1 Corinthians 1:29 NLT
https://bible.com/bible/116/1co.1.29.NLT

Why? Because what you are boasting with is nothing in God’s eye.

It’s like a kid is boasting his toy in front of an adult.

Therefore, as the Scriptures say, “If you want to boast, boast only about the Lord .”
1 Corinthians 1:31 NLT
https://bible.com/bible/116/1co.1.31.NLT

What does that mean?

So, if a priest boast how many people he has converted? Is that a good boast?

Or, if I boast about how much God blessed me? Is that a good boast?

If not, what should I boast?

God has united you with Christ Jesus. For our benefit God made him to be wisdom itself. Christ made us right with God; he made us pure and holy, and he freed us from sin.
1 Corinthians 1:30 NLT
https://bible.com/bible/116/1co.1.30.NLT

So, we boast about how Christ transformed us? Seems still not right.

OK. What Paul boast about?

If I must boast, I would rather boast about the things that show how weak I am.
2 Corinthians 11:30 NLT
https://bible.com/bible/116/2co.11.30.NLT

What does it mean?

Again I say, don’t think that I am a fool to talk like this. But even if you do, listen to me, as you would to a foolish person, while I also boast a little. Such boasting is not from the Lord, but I am acting like a fool. And since others boast about their human achievements, I will, too. After all, you think you are so wise, but you enjoy putting up with fools! You put up with it when someone enslaves you, takes everything you have, takes advantage of you, takes control of everything, and slaps you in the face. I’m ashamed to say that we’ve been too “weak” to do that! But whatever they dare to boast about—I’m talking like a fool again—I dare to boast about it, too. Are they Hebrews? So am I. Are they Israelites? So am I. Are they descendants of Abraham? So am I. Are they servants of Christ? I know I sound like a madman, but I have served him far more! I have worked harder, been put in prison more often, been whipped times without number, and faced death again and again. Five different times the Jewish leaders gave me thirty-nine lashes. Three times I was beaten with rods. Once I was stoned. Three times I was shipwrecked. Once I spent a whole night and a day adrift at sea. I have traveled on many long journeys. I have faced danger from rivers and from robbers. I have faced danger from my own people, the Jews, as well as from the Gentiles. I have faced danger in the cities, in the deserts, and on the seas. And I have faced danger from men who claim to be believers but are not. I have worked hard and long, enduring many sleepless nights. I have been hungry and thirsty and have often gone without food. I have shivered in the cold, without enough clothing to keep me warm. Then, besides all this, I have the daily burden of my concern for all the churches. Who is weak without my feeling that weakness? Who is led astray, and I do not burn with anger? If I must boast, I would rather boast about the things that show how weak I am. God, the Father of our Lord Jesus, who is worthy of eternal praise, knows I am not lying. When I was in Damascus, the governor under King Aretas kept guards at the city gates to catch me. I had to be lowered in a basket through a window in the city wall to escape from him.
2 Corinthians 11:16‭-‬33 NLT
https://bible.com/bible/116/2co.11.16-33.NLT

First, Paul has something to boast about, in world value system. But he think this is not worth to mention. Instead, he boast about his sufferings.

Why?

Paul revealed a truth: human being is vulnerable. You think you have wealth? Your wealth can be wipe away in a night. You think you are strong? A virus can easily make you sick. You think you are wise? Turns out everything you done is wrong.

Everything you owned is transcient and vulnerable, like grass can be easily withered.

Suffering caused vulnerabilities is what really happening to everyone. No one can escape that.

But, do you dare to suffer?

Paul does.

A man dare to suffer for Christ sake is a true warrior. He is the valuable person in God’s eye.

This boasting will do no good.
2 Corinthians 12:1 NLT
https://bible.com/bible/116/2co.12.1.NLT

Why?

As long as you are boasting about yourself, it’s doing no good for Christ.

Each time he said, “My grace is all you need. My power works best in weakness.” So now I am glad to boast about my weaknesses, so that the power of Christ can work through me. That’s why I take pleasure in my weaknesses, and in the insults, hardships, persecutions, and troubles that I suffer for Christ. For when I am weak, then I am strong.
2 Corinthians 12:9‭-‬10 NLT
https://bible.com/bible/116/2co.12.9-10.NLT

Paul is willing to expose his suffering. Sharing suffering itself is courageous. In worlds view, it’s a sign of weakness. But in God’s eye, it demonstrated God’s grace, God’s power. We can endure suffering is not because we are strong, but because Christ helped us, saved us.

Back to the beginning.

God has united you with Christ Jesus. For our benefit God made him to be wisdom itself. Christ made us right with God; he made us pure and holy, and he freed us from sin.
1 Corinthians 1:30 NLT
https://bible.com/bible/116/1co.1.30.NLT

He saved us. He can save you too.

God chose things despised by the world

1 Corinthians 1:28

New Living Translation
God chose things despised by the world, things counted as nothing at all, and used them to bring to nothing what the world considers important.

Contemporary English Version
What the world thinks is worthless, useless, and nothing at all is what God has used to destroy what the world considers important.

Aramaic Bible in Plain English
And he has chosen those of low descent in the world and the rejects and those who are nothing, to nullify those who are,

nullify: make of no use or value;

昨天带查的经文主题是关于God’s wisdom vs human wisdom

每次查完经回来又有新的体会。感觉没带好。

1:28是我选择的一个重点。让大家分享世俗的智慧和属神的智慧。

一说智慧,大家很容易联想到IQ, EQ什么的。或者科学知识。处事手腕。

个人觉得,这里的智慧是关于value system的。或者说价值观。what is important? what is not? or, who is a successful people? who is not?

why value system is important? because it determines your choices and actions. and your actions brings consequences. both short term and long term. more importantly, it determines how you think who you are? do you think you are a valuable person? do you think you are living a meaningful life?

联系上下文:

26Remember, dear brothers and sisters, that few of you were wise in the world’s eyes or powerful or wealthyg when God called you. 27Instead, God chose things the world considers foolish in order to shame those who think they are wise. And he chose things that are powerless to shame those who are powerful. 28God chose things despised by the world,h things counted as nothing at all, and used them to bring to nothing what the world considers important. 29As a result, no one can ever boast in the presence of God.

30God has united you with Christ Jesus. For our benefit God made him to be wisdom itself. Christ made us right with God; he made us pure and holy, and he freed us from sin. 31Therefore, as the Scriptures say, “If you want to boast, boast only about the LORD.”i

26节很清楚的说出了世俗的价值体系:wise,有文化的,比如有顶博士帽。powerful, 有权力的,比如帝王将相,如今的霸道总裁;wealthy,有钱的。有句俗语称呼美国梦的实现就是五子登科。跟这个差不多。

世俗世界崇拜有钱有权有知识的。有钱,有权,有名,有知识,这年头都是明星,都是网红。漫天遍地都是网红的八卦和讲话,剩下的就是成为网红的十条攻略。

反过来,价值系统决定了我们的自我评价。自我评价有决定了我们的快乐指数或者是痛苦指数。痛苦指数决定了我们的行为。

我们的行为又如何表现出来呢?

答案是boast,自夸,在29节和31节。

boast: talk with excessive pride and self-satisfaction about one’s achievements, possessions, or abilities.

一个人自夸什么,就说明他崇尚什么,或者追求什么。比如自夸泡过的妞有多少个,财产有多少,房子有多大,帽子有几顶,手下多少人,粉丝有多少,传道人自夸带领多少人信主,带领多少人的教会。

当然,大多数人是不会那么俗的。但是夜深人静,拿掉boast中的talk,我们会satisfy什么东西?

与boast和pride相对应的是shame。

我们会因为缺少什么而觉得shameful?

A bit care brings big reward

今天去踢球,回来的路上,nihao又从后面骑车跟上来了

他是个波兰人,球踢得好,场上非常敬业,总是全场奔跑最积极的那个

我问他,你们打完了?

我走的时候他们约好最后再进两个球就结束。我收拾东西的时候已经进了一个了。

nihao说,是的,他们很快就进了两。

我看他没有背包,感觉有些奇怪。就问他,你在办公室就换上衣服了?

他开始没听懂。

我又问了两遍,说你在办公室就把短裤换上啦?

他终于有些明白。很快陷入深思。然后突然跟我说

啊,坏了,我的包搞忘拿了。

于是转头去拿包。

我骑自行车到了办公室楼下。发现手机竟然不在书包里!

也不再裤兜里!

找了一圈也没有找到。

这下完了。

而且还得马上开会。

没办法,拿了点儿吃的,回到办公室。

刚刚坐下,同事走过来跟我说得开会了。

就一起去了会议室。

开了一半。有个人推开门。

是nihao!他递给我手机,说在球场找到的。

感谢主!

我问他怎么知道是我的?

他说上面显示了meeting房间。

真是感谢主!

如果我之前没有问那些问题,他就会忘记他的包。而我也得回头去找我的手机。

真是万事相互效力。

又得flu了

前两天就开始觉得肩膀隐约有些酸痛

昨天下午回到家吃完饭出去走路,越来越痛。到家后痛得不行。贴了副狗皮膏药。不顶用。

吃了泰诺和Ibuprofen,很快睡着了。早上四点就醒了。肩膀好多了。

看来每次出门旅行回来基本都得病一场。

3D打印

11周年结婚纪念日就要到了

后天又要出差了

虽然很忙,今天还是赶紧请了半天假

跑到公司的garage

现学现做

找了个不要求上课的up打印机

下载用户手册

好几十页文档

快速扫了一下,又把最重要的calibration部分仔细弄了一下

调了一下参数,感觉上对了

下载一个测试模型

开始两次竟然软件直接crash了

后来设置了一些东西,不知道怎么又好了,感谢主

然后提示要打印两个多小时。。。就一个小的模型

不过感谢主找到stop button

又跑到tinkercad上赶紧设计个三维模型

很简单的一个板子,加上一些字

花了差不多一个半小时,效果是这样的

下面的字因为太小,打印机分辨率也不高,基本上废掉了

不过总体上任务完成了。感谢主。

原始设计图是这样的:

flood, capacity, efficiency, throughput

最近听jordan peterson的biblical lectures

学到很多有意思的perspective

比如flood象征chaos,disaster

而chaos, disaster又可以用complexity来表现

如果我们的capacity, resources无法handle complexity,我们就是被flood给湮灭了

而flood会随时在我们的日常生活中出现

最近工作焦头烂额,就是因为碰到一个又一个的bug,而在解决bug的过程中又碰到新的bug,阻碍你去解决最开始发现的bug。而之前别人写的东西又贼复杂,光理解就得花很多时间。complexity is overwhelming。

跟老板meeting,最近注意到两个词,capacity, throughput

其实,我们每个人就像一台human flesh machine。牛人throughput高,capacity高。解决复杂问题的能力强。

那怎么提高我们自身的processing power呢?

又被咬了

本来觉得可以launch了

结果老板一查,说这分好几个change,每个change要单独证明一下

结果就又傻眼了

哎,还是怪自己做事不够细致,不够全面

或者,喜欢assume一些东西,然后省略一些东西

以后还是得老老实实,每个步骤都得有板有眼才行

其实这几天另外一个事情也是类似

assume数据是好的,上模型,上实验,结果发现有问题

一查是数据问题,程序bug引起的

这一下又浪费了好几个礼拜

虽然程序不是我写的,但是我做事儿也没有到位

每一步应该都verify才行

省略一小步,后面就浪费了一大把

贪功求快,这是不是人性的罪呀?
