Have you tried terminating the EC2 instances abruptly to test the resilience of your solution?

aws ec2 stop-instances \ --instance-ids i-12345678 \ --skip-os-shutdown

The negotiatons can be considered a big success because Israeli leaders did not order the murder of the negotiators this time. This will open doors for more realistic negotiations in the future.

Java can work with transparent hugepages (in addition to preallocated hugepages), but you just use +AlwaysPreTouch to map them in during the startup so that at runtime there won't be any delays or jitter. Redis should add a similar option

What options are there?

1. Manufacturing defects in satellites. Either accidental or sabotage.

2. Someone using them for target practice. With an energy beam or projectiles?

Did both of the satellites happen to be over the same region of earth?

I would recommend using PTP on all clouds. The accuracy is more than 10x to NTP. It consumes less CPU. It does not use network traffic and thus can not be attacked, even if UDP is open to internet or if network stack is under DoS.

All clouds except AWS is easy: just `modprobe ptp_kvm` and point chrony at /dev/ptp0

On AWS it depends on instance type: some older do not support it at all, some support it via the network driver, some via the kvm PTP driver.

New comment by gmokki in "Kafka is Fast – I'll use Postgres"

gmokki — Fri, 31 Oct 2025 07:07:01 +0000

Don't you always need a database after reading events from Kafka to deduplication?

So the competing solutions are: PostgreSQL or Kafka+PostgreSQL

Kafka does provide some extrs there, handling load spikes, more clients that PG can handle natively and resilience to some DB downtime. But is it worth the complexity, in most cases no.

I think he was trying to say that phone theft can benefit the same way as credit card theft. The thief uses the phone to buy stuff before the user reports it stolen. In this case the stuff that is bought is mobile services that are billed for example 100€ for each SMS message. The victims mobile subscription plan gets the bill and the associates of the thief get the money.

I have bookmarked the play store update view as separate icon by long pressing the play store icon, then long pressing/dragging the my apps section to an own "app".

That way I can skip the store garbage and directly go click update all apps button.

I just tried on apple device s few weeks ago and it took me many minutes to find the listing where I can update installed apps and it was missing the update all button...

If there is no sprained ankle diagnostics and doctors just tell you to ignore not being well: just jump and run around as normal there is nothing seriously wrong.

And doctors only react when you can no longer use your legs for a year, otherwise they must be amputated.

Or would you rather have an earlier disgnostic with instructions to reduce extreme loads and try to take it easy. Let's check again in a week.

New comment by gmokki in "The future of large files in Git is Git"

gmokki — Sat, 16 Aug 2025 14:16:47 +0000

I've been thinking of using git filter to split the huge asset files (that are just internally a collection of assets bundler to 200M-1GB files) into smaller ones. That way when artist modifies one sub-asset in a huge file only the small change is recorded in history. There is an example filter for doing this with zip files.

The above should work. But does git support multiple filters for a file? For example first the above asset split filter and then store the files in LFS which is another filter.

The gas station is supposed to release the authorization after the real payment clears when you stop the pump. So they should not pile up even if you do many visits in short period of time.

In Finland the has pump firsts ask you to choose how big an authorization you want to do when you enter your card to the slot. It will not allow you to pump more than that and the authorization is then replaced by real charge before you enter you car.

I would assume that the engines cur of due to fault in the shared control system. And to restore power the pilots toggled the switches to off and then back on to get them running again.

Hopefully the timestamps tell if the engines lost power before switches were turned off? Or is there some time window that was not recorded due to the lost power to systems?

gmokki — Sun, 06 Jul 2025 15:40:05 +0000

Why would btrfs or btrfs snapshot require single disks? My btrfs is combination of different size disks bought over time (3T to 24T) and snapshots works just fine. I've configured it to use raid with 2 copies for data and 3 for metadata.
