At this time,
some people worry about where to go for fun,
some worry about not being able to buy tickets,
some worry about not being able to book rooms,
some worry about not having money to go out,
and some are even worse… they don’t get a holiday at all.
Last night I had a nightmare:
HR sent a company-wide notice in the group,
with the title [No Holiday Notification for Labor Day]…
Followed by six words: Salute to the workers!
I was furious, opened the group to prepare to curse,
just sent a sentence of national essence (net censorship),
accidentally sent it to the entire company group,
and right below the no-holiday notice.
Seeing my career about to end,
Meng Ge replied below:
“Are you crazy? Cursing me here.”
I immediately went to Meng Ge and bowed to him.
Then, I crazily shouted slogans in the group:
“The earth won’t explode, I won’t take a holiday!”
“The universe won’t restart, I won’t rest!”
“I love overtime, overtime makes my boss happy!”
Before:Don’t worry, be happy.
Now:Don’t work, be happy.
The holiday is coming!
This feeling of being released from prison is too intoxicating.
Every time a short holiday approaches,
in the days before the holiday, I become very restless,
fantasizing about the wonderful life after the holiday.
I asked Meng Ge: Where do you plan to go for fun on May Day?
Is it barbecue in Zibo, or the Water Splashing Festival in Yunnan?
Go to Luoyang to see peonies, or go to Guangxi for mountain songs?
Or… catch river fish, and egg-laying hens,
the toads of Changbai Mountain are the best, shall we go?
Meng Ge wrote the two words “serious” on his face:
“I asked my friend who does tourism,
“What preparations are needed for traveling on May Day?”
He said, in summary, just four words: Bring more money.
“With your income, a true Jiangnan,
will spend all the money in your pocket!”
Why can’t you find a yacht in Sanya or a five-star hotel?
Think about it, think carefully!
Ah, my goodness, precisely pinpointed…
Going out to play is not as interesting as watching videos at home!
May Day is five days of fun, leveling up is the happiest:
Digital Circuit: Build a Computer from Scratch Tutorial
Direct link to Bilibili:

The Shanguigu Embedded Series Tutorial on Digital Circuit: Build a Computer from Scratch does not require learners to have any basic circuit knowledge. Even if you have never heard of digital circuits, following this tutorial step by step will allow you to eventually complete the entire practical project and build a computer from scratch!
The tutorial is divided into four main parts: The first part covers basic principles of digital circuits and gate circuits to help everyone solidify their foundation and familiarize themselves with operations; the second part introduces the Von Neumann computer model, which is the model used by most computers today; understanding the target model is key to better realizing it; the third part involves creating computing units, i.e., building the core computer hardware, which is the most crucial step in handcrafting a CPU; the fourth part involves packaging and merging the computer for practical demonstration.

Do not be intimidated by the enemy’s fierce momentum,
do not be discouraged by the difficulties that can still be endured,
do not lose heart because of temporary setbacks,
the road is winding, the future is bright,
the darkness is about to pass, the dawn is right ahead!
I stole Li Bai’s wine, wanting to drink with Du Fu,
Su Shi sent Dongpo meat, drunk in front of Wang Wei’s door.
Once I got drunk, and said to Meng Ge:
I want to go back home and open a milk tea franchise,
being PUAed by the boss every day makes me emo.
Meng Ge suddenly said seriously:
If anyone tells you, I have a good project,
low investment, high profit, and low risk,
remember, however far your thoughts go, run however far.
Trust him? Better to trust I am Qin Shi Huang!
Why would such a good thing find you?
Be careful, you might lose your pants.
Your entrepreneurial income,
is far higher than being a screw;
but the risk of entrepreneurship,
will also be far higher than being a screw.
Especially businesses that look clean and fresh,
milk tea shops, coffee shops, cake shops, flower shops,
look beautiful, but actually –
low threshold, serious internal competition, and fierce competition.
Don’t be fooled by marketing!
What’s the first cup of milk tea in autumn…
soft and hard to swallow = sticky,
hard and dry = the more you chew, the more fragrant,
bad-tasting internet celebrity shops = the shop is super photogenic.
Clearly added a bunch of things but still tastes bad,
must talk about how rich the flavor is.
Directly eating bad food can only be a mess,
but still insists it’s the divine method I finally found.
Can’t open in big cities, go to third or fourth tier cities,
pay attention to this little hint:
“xx queue king, finally came to my big xx!”
“I xx took a bite and opened a shop on the spot.”
When you confidently open a shop,
you will know what a societal beating is.
Truly listening to your words, I want to be cremated on the spot.
Entrepreneurship has risks, investment requires caution…
If there are no particularly suitable opportunities,
let’s learn some technology from Meng Ge.
Hit the bottom left corner “Read the original text”,
the old driver will drift through the bend together!
