Indeed. You want to have small buffers, because big buffers increase WIP (Work In Progress), product gets damaged, problems are hidden, etc. That follows the JIT (Just In Time) ideas. But, you still want to have buffers to decouple both operations. You also want to constraint the size of the buffer, where the producer stops when the buffer is full. In the case of queues (As in AWS SQS), I am not aware of any limits where you can also stop the producer when the queue reaches a size. I believe it is desirable just from my experience on Manufacturing systems back in the day.

Back in the 90s. I was part of a team working R&D project on flexible manufacturing. One of the central concepts was the use of buffers (also called decouplers) between manufacturing stations. These buffers were the space needed to place not finished products while they waited for the next station. Typically a conveyor belt. The main service is that both stations could run at slightly different rhythm, and they would not be causing problems on the other one. Either starving it or overwhelming it. Queues are pretty similar. You can have a consumer and a producer working and the queue in between prevents them from being blocked by each other. Thus I now see the main role of queues as decouplers.

The people living in uk now are not the same people who were involved in past invasions.

Exactly. With the standard rules, it is easy to buy the stock to opt in. If they change the rules, it is very hard to opt out if your portfolio follows the S&P500, like many passive investors do.

Just expanding on this. In hispanic countries we have two last names. One you get from your father side and the other one you get from the mother side. When the first last name is very common like Lopez, Garcia, Perez, etc. it is common practice to keep the second last name when you are talking about them. Otherwise it sounds too plain. Like Gabriel Garcia could be anyone, but Gabriel Garcia Marquez is a renown author.

My experience dating someone younger. She was still in college and I was already working full time. I noticed that if we stayed late night on the weekend, she would make the sleep back during the week, may be in short spans, here and there. But once you work full time, you cannot. At work, you have be up and ready all day. So you carry a sleep debt for a long time. Once, she started working full time, she was as tired as me.

The least prolific very successfull author in the world was perhaps Juan Rulfo. He only wrote 300 pages in his whole life and lived to be 68. It is really hard to explain how was he able to produce such master works.

I agree. The rich kids will always have an advantage. But let me ask why are we playing this like a zero sum game? Do we not have enough education for anyone who is willing to put up the work?

I think providing access to remedial resources, free meals at school, do more for disadvantage students than lowering the requirements. Also make sure there are enough slots for anyone who is able to pass the requirements.

Property taxes have the added benefit to lower property prices, and the money can go on improving the city. (Which make properties prices go higher)

A bit Off topic. I am looking for a Board Game for my step dad. He is a retired 80+ years old rancher. He doesn't know any english at all, so he is very limited on choices. Something that can be played by himself or with other person.

I also think 100x is an exageration. May be 5x for producing coed ? And in terms of understanding, may be 2x.

Nice breakdown! I would separate the Hardware era between Mainframe era and PC era. I would extend Internet era a bit more, Perhaps 2007 when the IPhone was released.

Edit: I hadn't seen the original presentation yet. I see that Evans already divided the eras like I suggest above.

Beautifully said. Well rounded, thoughtful people improve life for all of us. Of course, we also need practical skills to make a living. But we can have both, they are not mutually exclusive.

I am seeing this phenomenon in my country. Once people discover that their beloved leader is corrupt, they just justify with "all politicians are the same". Society becomes so cynic that it very hard to bring change. Politicians are considered corrupt by default, I don't know how that ends.
