If you want a consistent backup that you can use to setup a replica you need to block writes while the backup is taken, take the backup while the database is shutdown OR use xtrabackup.
The "making it catch up" is the tricky part. You need an initial backup for that. xtrabackup can take that backup "hot" without blocking read/writes. mysqldumper will block writes for whatever time that initial backup takes, for 2TB of data that's going to be hours.
Once you have that initial back up you can set your replica and make it catch up , then you switch. I choose to take the few seconds of downtime doing the switch because for my use case that was acceptable.
If you’re migrating a large MySQL database and you’re not
using mydumper/myloader, you’re doing it the hard way.
If you aren't using xtrabackup you are doing it wrong. I recently migrated a database with 2TB of data from 5.7 to 8.4 with about 15 seconds of down time. It wouldn't have been possible without xtrabackup. Mysqldumper requires a global write block, I wouldn't call blocking writes for hours a "zero downtime migration".
On a computer click click is a lot slower since you have to come to a complete pointer stop in your release. If your pointer is still moving in the release square most interfaces would detect that as some attempt to start a drag
This doesn’t make any sense. Click and click is slower than click+drag, it’s just obviously two extra movements (a full extra press and an extra release).
You can also drag and hover while waiting for the opponent move and release if the expected move shows up or right click to cancel the drag if not the expected move.
Also dragging and hovering over your target square is super useful to visualize your move and catch any last millisecond mistakes.
I do t think any of the top bullet/hyperbullet players does click and click. I think I have seen Magnus doing click and click in very old chess24 blitz videos but I’m not sure he did that in lichess playing bullet orin chesscom scc for example.
Everything is out in the open nowadays. Kids can start learning whatever they what an younger and younger ages.
A perfect example is chess. It used that a lot of knowledge was in books, often in foreign languages. Nowadays everything is out there in the open and additionally you can casually play games against top 100 opposition once you are okeish enough accelerating the development even more.
They aren't blocking anything. They are just asking nicely not to be crawled. Given that AI companies haven't cared a single bit about ripping of other's peoples data I don't see why they would care now.
Others have commented on other parts of the letter but I find it very amusing he is basically stuck in a 2006 view of the tech world. Slashdot and HDD seek times immediately jumped out as things are as dead as they can be.
I wonder if he even knows about smartphones.
