jpablo··on OpenAI GPT–6 Astra breaks Enigma message that has resisted solution since 2005
Why wasn't this in the article?
jpablo··on Unauthorized alert sent to cell phones across Brazil
The power to send mass messages to a whole country is the worst thing google/apple have given to governments across the world.
jpablo··on Getting arrested in Japan
Darn. I don't know if I have been living in the wrong places but I never see drug-addicted homeless people in my western country at night.
jpablo··on Migrating from DigitalOcean to Hetzner
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.
jpablo··on Migrating from DigitalOcean to Hetzner
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.

jpablo··on Migrating from DigitalOcean to Hetzner

  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".

Yeah... that's way, way, way more complex than npm run dev

jpablo··on Fixing the mechanics of my bullet chess
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
jpablo··on Fixing the mechanics of my bullet chess
Not having the right click to cancel a drag would certainly be a huge difference
jpablo··on Fixing the mechanics of my bullet chess
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.

jpablo··on Liberating Wi-Fi on the ESP32 [video]
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.

jpablo··on GPT-5 is behind schedule
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.

There's a spanish saying: Ladrón que roba a ladrón tiene 100 años de perdón.

jpablo··on Hans Reiser on ReiserFS deprecation in the Linux kernel
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.

Update: As of right now Slashdot.Org hasn't posted this

jpablo··on Nintendo Network shutdown – The beginning of the end
no, nintendo ships complete playable games.
jpablo··on HP raising Instant Ink subscription pricing significantly
I was researching a brother laser recently and there were a shitload reports of the printer crapping out with non original toner after a power outtage. Also if you were buying non original toner you had to transfer your drm chip to the new toner.
jpablo··on HP raising Instant Ink subscription pricing significantly
I feel like the brother info is outdated. New brother lasers printers check tonner drm and have a tendency to get it wrong even with original toner.
jpablo··on World breaches key 1.5C warming mark for record number of days
Well the actual paper he's basing all of this is here:

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/202...

The authors of the paper suggest a +0.15 Wm−2 radiative forcing and give the radiative forcing increase due to CO2 form 1996 to 2005 as +0.26 Wm−2.

This seems to provide an explanation of a huge jump in temperatures non expected by current CO2-only models.

Why this effect would not have been seen in the summer of 2022 I don't know, nor seems the authors of the paper or the liked article address it.

Also the author says this effect may dissipate in 5-10 years at which point the expected warming from CO2 would "match" the current temperatures anyway so there's no real 'cooling' to be expected.

jpablo··on World breaches key 1.5C warming mark for record number of days
There was an article here recently saying that the recent extreme heat was caused by an under water volcano shooting vasts amounts of water vapor to the stratosphere and that the warming caused by that event will subdue in 5-10 years.

jpablo··on Two men got jobs at Amazon just to steal copies of Zelda
While what you are saying makes sense the reverse is also true: In the long run would I be happy that I stayed at work that one extra day instead of playing Cyberpunk 2077? Years from now would I conclude that extra day at work instead of having fun was worth it?
jpablo··on Can you stop your open-source project from being used for evil?
OSI couldn't trademark "Open Source" and the common usage of the term (source available) has steered away from the OSI definition.
