10. ESP32 based old clock controller, with NTP sync

There is a clock in my house that is connected to a central clock system. The system works by having a "master" clock that tells all the other clocks what time it is. The master clock is connected to the Internet, so it can get the time from an atomic clock. The master clock then sends the time to the "slave" clocks, which are clocks like mine that are not connected to the Internet. The slave clocks can't get the time from an atomic clock, because they don

The clock is synchronized to the grid. The grid is synchronized to the power source, which is synchronized to the grid. The grid is synchronized to the power source. The power source is synchronized to the power source.

12. Would it be possible to detect an industrial civilization in geological record?

You will not be able to tell if the climate was changed by aliens.

The Younger Dryas was a period of rapid cooling in the late Pleistocene 12800 to 11500 calendar years ago It followed closely on the heels of a dramatically abrupt warming that brought the last Ice Age to a close 17500 calendar years ago lasted for about 1300 years then ended as abruptly as it started The cause of these remarkably sudden climate changes has puzzled geologists and climatologists for decades and despite much effort to find the answer can still only be considered enigmatichttpswattsup

13. Towards Principled Reactive UI

When you make a computer program, you have to decide how to organize it. There are many possible ways to organize it, and each way has its tradeoffs.

You can use Rust to make a program that is fast and easy to use. For a program that is easy to use, you might want to trade off a little speed. For programs that need to be easy to use, you might want to use a different language. For example, if you need to make a program that is easy to use, you might want to use a language that lets you use closures. Closures are very useful when you need to make a program that is easy to use

14. A Short Story for Engineers

The toothpaste factory had a problem: sometimes the tube of toothpaste was not inside the box. The factory tried to fix it, but could not do it well. So they asked outside experts to solve the problem. The experts looked at the problem and decided that the best way to fix it was to have a machine that would stop the line if a box was missing the tube. The machine cost $8 million, but it worked very well. There were no more boxes without tubes.

The company wants the workers to think of ways to save time and money, so they offer a prize to whoever has the best idea. But the company doesn't want the workers to just come up with any old idea, because that would cost too much money. So they tell the workers, "Don't worry about the cost. If your idea is good, we'll find a way to pay for it."

18. My Hacking Adventures with Safari Reader Mode

In March 2020, I found a new way to trick the computer into doing something it shouldn't do. It's like telling someone, "You can go ahead and eat this candy bar because it's not really candy." Then they eat it and get sick. The computer is tricked into running a program that it shouldn't run.

Its a security issue with the Safari browser that lets you see webpages without the ads and other junk that webpages usually contain. Safari is made by Apple, and there are several websites that have articles about how to use this exploit. It lets you see webpages without the ads and other junk that webpages usually contain.

When you see a Tweet you like, tap the heart — it lets the person who wrote it know you shared the love.

The computer is a machine that does what you tell it to do. There is software that lets you tell it to do different things. There are different kinds of software, like the software that makes it run Windows, or the software that makes it run Linux. The software that makes it run Linux is called "Linux". It is free, just like the word "free" means you can use it for free. The free Linux software is made by lots of people all over the world, and they

The cost of flying a plane is mostly the cost of the fuel and the pilot's salary. The pilot's salary is about $100,000 per year if the plane is a Boeing 747. If the plane is small, it costs less to fly, but still more than $100,000 per year.

23. The Endless Frontier Act

The government gives money to the National Science Foundation to give to other organizations. The money is given with restrictions. The organizations are risk averse. The money is given to risk averse organizations (universities) into a system with increasingly risk averse incentives.

It seems to me that all the economic criticisms of grant writing and funding committees are things that can destroy value. It distracts people who actually know science. It makes short term bets. It encourages fashions. All of these things could just as easily apply to venture capital. What's really different is that venture capital tends to make members of the elite even richer. Imagine an angel investor putting in some seed money for 5% of the company, then a massive series A from government VC. The

24. Comments by a developer inside the Windows Media Player source code

Media Player is not handling key up events correctly. If you hit a key, then release it, then hit it again, Media Player thinks you're holding down the key the whole time.

26. Developing a reactivity system with Lamport clocks and incremental computation

A modern JavaScript reactivity system powered by Lamport clocks and incremental computation and depthfirst searches oh my

It's like the difference between a plain old number, and a number with a dollar sign in front of it. The dollar sign means that the number is special, and if you add or subtract it from something else, you have to remember to add or subtract the dollar sign too. The dollar sign is like a pointer to the number, and the number is like the thing that it points to. So for example, if you have two numbers, one with a dollar sign, and one without,

"The IRS wants to know if you have any money from selling things, like your old stuff on eBay or your used car on Craigslist, and if you do, they want to know how much money you made from it."

The IRS is a government agency that collects money from people. In the past, it was not very good at collecting money from people who were rich and powerful. The IRS was not very good at this because the people who were rich and powerful paid lots of money to politicians so that the politicians would say that the IRS should not collect their money.

30. Lost Languages Discovered in One of the World’s Oldest Libraries (2017)

The monks at St. Catherine's Monastery in Egypt were running out of paper. So they took old manuscripts and scraped off the ink, and wrote over the blank paper. Now, modern researchers are using cameras to take pictures of the pages, and special light to show the writing under the new ink.

In the past, some people have found some old scrolls. They were written in a language that we don't know how to read. But now we can read them.
