The tv does care which port it came from, since it automatically switches to the one which made the request. One could build a IR emitter but you need soldering skills for that or buy a usb one which cost north of 30€ + shipping.

There is sadly no hdmi CEC support on Most GPUs for pcs. So when you want your tv to turn on and off with your pc it is only possible with the tv being reachable from your pc via ip. I believe LG doesn’t advertise such an api via Bluetooth

to not let the bytes i forward enter userspace, i serve from the page cache for the asset path, directly from a zip file. i open the file, mmap it, close it and tell io_uring_prep_send which bytes from the mapping to send, this also saves m

How can one memcpy from a fd to a socket? I don’t touch the bytes in userspace, I just tell the kernel to send them out.

For responsiveness that’s what you want, context switches add quite a lot of jitter and perceived slowness’s, making your app feel slow despite running at 120 fps.

Tried every way to get contents of a file as fast to a client socket as possible. mmap and io_uring_prep_send were faster than everything else, no matter the size as long as you keep the map around for the lifetime of the process. for one o

In my case: its a PROT_READ, MAP_PRIVAT map and i cannot get a SIGBUS since i tell the kernel to handle it all for me, thanks to liburing, instead i get a short send in that case.

To be more precise: i use that map to send assets out directly to clients from a zip file. Its a new web server i am building and its the fastest way i could find out. Just switching from epoll to liburing made the server ~45% faster too, i

I found out that using mmap and just telling uring to read form there to beat anything else.

You can have virtually unlimited amount of rules, its just a limit per list, the number of lists aint really limited.

The main Question is: why do you allow clients to connect to your database server, it should be limited to a server which could actually serve the data in a format the client can just render without any logic client side.

Network IO is heavily NIC queue bound, if your NIC only has one queue it just makes it slower to do any threading workload against it. On my ryzen 9 it needs around 8 cores to do the same work in a threaded io loop than you can do single th

Just curious, can’t this be done using a bookmarklet? Albeit it being a bit clunky to use compared to a userscript which runs automatically.

Wait, does this mean we can „virtualize“ ld.so now? This could finally solve the compatibility issues glibc causes.

All we need to do is to replace all plastics with bio degradable ones. But I guess that will take some time since we don’t have replacements for all petroleum based plastics yet. Hopefully this will get us recycling friendly plastics for fo

The system we got for this is called parenting. And there is a saying where I grew up: you need a village to raise a kid, I feel like we lost track of that and feel the issues of that now. Btw, von der leyen is trying to get stuff like this
