yeah
apparently if there are a lot of syscalls the performance will be worse
i wonder when newer processors will be released that don't have this flaw

These KPTI patches move the kernel into a completely separate address space, so it's not just invisible to a running process, it's not even there at all. Really, this shouldn't be needed, but clearly there is a flaw in Intel's silicon that allows kernel access protections to be bypassed in some way.
so everytime a systemcall occurs address space is switched to kernel and back. with a full cache dump.
ouch keeps intensifying
Archomeda
@Archomeda
Jan 04 2018 00:15
it's funny how the kernel is supposed to not trust userspace at all and has to verify everything, but what about kernel verification?
or even hardware verification
yay :fire:

well in this case you'd still need enough people who understand branch prediction wizardry, even with open source hardware
Archomeda

yeah...
i only got the gist of it in college
but that's just the rough information about how it works, not anything more than that

¯\_(ツ)_/¯
you could work for an ARM licensee
there's also a good number of groups that do FPGA/ASIC development for fintech firms
becoming proficient with VHDL/Verilog is actually really rewarding, financially, from what I hear
Archomeda
@Archomeda
Jan 04 2018 00:22
oh god... from what i did in VHDL, it was awful
then again, we probably worked with outdated stuff
had to program a microchip... but in order to upload the code to it, we had to use... erm... a very, very old pc
heh
Archomeda
@Archomeda
Jan 04 2018 00:26
anyway, @lye, is there any chance you can get some easy and trivial stuff done on the api?
yeah that's probably just old hardware, you can get USB chip programmers these day and use whatever machine

amazing how many website depend on AWS rebooting ^
Archomeda
@Archomeda
Jan 04 2018 00:28
can't really remember, i think it was an FPGA chip, but it's been a while since i've done that, and i didn't really enjoy it
oh did the aws reboot happen?
Werdes
@werdes
Jan 04 2018 00:29
wasn't that supposed to be on friday?
Archomeda
@Archomeda
Jan 04 2018 00:29
just make some code to let the chip do stuff, and we had to verify it was doing it correctly by putting it in a different device
I'm not sure
I haven't seen any emails internally about it

https://aws.amazon.com/security/security-bulletins/AWS-2018-013/ i guess amazon has moved the scheduled reboot to now, instead of at the end the week

All but a small single-digit percentage of instances across the Amazon EC2 fleet are already protected. The remaining ones will be completed in the next several hours, with associated instance maintenance notifications.
I don't know if that'll affect us

@Archomeda
Jan 04 2018 00:32
aren't you running gw2 servers in virtualized environments though? as far as i understand, the host needs to be updated as well as the guest(s)
updating the underlying OS
yeah we don't do that

also, can i flame amazon? i still have ping issues
yeah
fwiw we're not really sure what's up with that

for some reason my ping has been fluctuating in raid instances, but not in open world instances...

it's probably worse that this time it's a hardware bug in billions of devices which has to be fixed by software butchering

the more details of it surface, the more i come to think the original pentium bug back in the 90's was a joke in comparison
(it was for sure in scale and the media had a completely new thing to report about)
were there any other incidents like that where a vendor made a hardware recall?
smiley

oh, that was before i learned how to write the word "bug" i guess :D
happy 20th birthday, F0 bug! https://en.wikipedia.org/wiki/Pentium_F00F_bug
pretty sure this is not a coincidence

New discussion in API Development:

Leaving Selfless potion on all the time.
by Voe.3051 in API Development

Hello!! Thank you for making such an awesome game! Wasn't sure which category to post this in, but I was wondering if you might consider us being able to leave the selfless potion on all the time...or at least until we turn it off ourselves. Currently, I have to turn it on when I log in, when I enter my home instance, when I rez...I think when I enter WvsW and the guild hall too, but I can't quite remember. Anyway, for me, it's a part of my character's outfit, and it gets tedious turning it back on all the time while I'm playing. OK, thanks again for considering my request! =->

debian is fine, but extremely slow when it comes to stable php releases

ubuntu 17.10 works like a charm (for me at least)
also, running phpstorm on linux is like unlocking the secret levels :D

I keep seeing everyone saying that docker is the future but..it seems like a hassle managing 5 docker containers for 1 website
Archomeda
@Archomeda
Jan 04 2018 21:57
eh, whenever i push something, docker hub compiles it into an image, and there's a separate container running on my docker instance that checks if there's a new docker image version of any of my containers
and because i've linked my docker hub repo with the nodejs image, it even compiles a new image whenever nodejs is updated
although, you have to be careful with this ofc
