Imagine, you race hard long map, and after 3 hours walkthrough you both get timeout and can't reconnect(doesn't matter why)

Why there are no autosave on ddnet servers?

Because we have no accounts, so how do we assure that the correct person gets the save password?

is that a real story? imo it does matter why you can not reconnect. Timeout usually works great for me :)

I usually cant reconnect cuz electricity goes down justatest

make autogenerated password before player's internet dies, then when both did timeout-save and write that save to ddnet-saves.txt

So timeout but its forever and the tees disappear instantly?

I guess the reasons against this are the same like for /save in t0. Skips..

Doesn't /save already show everyone the save password

Encrypting data at rest is vital for Cloudflare with more than 200 data centres across the world. In this post, we will investigate the performance of disk encryption on Linux and explain how we made it at least two times faster for ourselves and our customers!

Quite funny how the dm-crypt mailing list told them they don’t understand
16:24
I might try this, apparently it made it into the kernel. It may help explain why I only get like 30M/s writing into a luks partition on an ssd

@Learath2 just skimmed but are they putting the improvements to upstream?
16:36
also as always excelent blog

Already did, it’s on 5.9

Tldr is a lot of outdated legacy code to accomodate for the limitations of the past

kernel stack or smth

4 queues

E.g. bad random read/write speed of traditional drives. Kernel stack size limits etc

meh, bad mailing list apparently 😦

I expect a lot of these older mailing lists full of kernel hackers and the compiler people are all similar

telling others you know better when you do is already iffy
17:44
but if you don't, that's just bad
17:46
But for the sake of stability and further benchmarking we ended up not removing the actual code, but rather adding yet another dm-crypt option, which bypasses all the queues/threads, if enabled.
17:46
yay, options \o/ :p
17:46
I also had problems with dm-crypt devices in the past
17:46
never debugged them though
Avatar
In this case options might actually be good, since their approach might not be strictly better for all workloads
17:47
E.g. a traditional spinning rust drive does indeed have a significant difference in sequential vs random performance
17:49
Does anyone know how I can fix an ext4 partition to patch the size?
Avatar
to expand or shrink?
Avatar
I imaged a partition and the new one I created seems to be like a couple bytes shorter for some reason
17:50
Now when I write the image onto the partition fsck complains that the physical size doesnt match the fs size
Avatar
resize2fs sounds interesting?
Avatar
Yep, that worked
17:58
I’m never imaging a drive like this again, such a bad idea 😄
Avatar
why? ^^
18:01
why is it a bad idea?
Avatar
@heinrich5991 well it doesn't check bounds of the partition, what I did wouldn't have worked with a completely full partition e.g.

no, only you see the password

Ah okay then

Patiga
no, only you see the password
it shows everyone from the team the password, no?

true, not the entire server though

ah I might've not read enough context
