You may as well have said "Im glad im not the only one who noticed Linux/Mac OS is slow" or Intel/AMD is slow or bash/fish/ksh is slow

My working understanding is that a program is common to run on these OS'es/hardware/shells :/


I am glad I’m not the only one who noticed Linux/Mac OS is slow

The article mentions you cannot use the app until its been updated


Hm, I don't think I said that. I think this is more of PR issue than anything else


Not saying you're wrong, but go read the criticisms of Tesla when it first started, and your comment mirrors those.

Of course there are difficult hurdles to overcome, otherwise everyone would be doing it

I dont get it. How would a computer solve this?


If you want an extensive answer, I recommend the neural network playlist on 3Blue1Brown: https://www.youtube.com/watch?v=aircAruvnKk&list=PLZHQObOWTQ...

Are you sure? This was the case in mysql 5.5 but 5.6 and up will not take the table offline anymore.

> Several ALTER TABLE operations can be performed without copying the table, without blocking inserts, updates, and deletes to the table, or both. These enhancements are known collectively as online DDL. See Section 14.13, “InnoDB and Online DDL” for details.

No, but it would take so much CPU and OI, it might as well. I doubt the application would be in great shape while this operation took place.


Are we sure this is not a step backwards? We woild benuaing.less water, but filling our lakes with lubricant?


From a comment above from the developer, it seems this stuff (particularly the second coating) is akin to hair conditioner.


Is this applicable to mysql?


You might consider running "EXPLAIN" to see for yourself.


Mysql's explain is very difficult for me to understand compared to postgres...


Both give the exact same result.


Well fill a table with a few million rows, and compare the results. If they both come back with the same rough times then you've learned they're both equally good :)

Sometimes its good to ask people "Is this true of XX?", but but if you're curious it almost takes less time to expore and test than wait for somebody to give you an answer - an answer that might actually be wrong. (Some things change across DB-releases, as I've learned to my cost. If I'm ever unsure of whether one approach is faster than the other IN MY SPECIFIC SITUATION I would test. Random benchmarks are often not as useful as real-world tests.)
