I should probably write a blog on how to do this. I have a setup guide for myself, but unfortunately it contains a lot of obviously private details that I can't post (ie access to my cloudflare/VPN stuff). A lot of my stuff is ad-

Can I heavily recommend the use of them as a pihole + Wireguard VPN + DNSCryptProxy Server. Pihole -> Great use for a network wide adblocker/DHCP server. Wireguard VPN -> In combination with a DDNS setup and some port forwarding

Have you used bangs with DDG? https://duckduckgo.com/bang This is the killer feature for me because if I know I want to search wikipedia, reddit, amazon, pydocs I can directly. If my search results are kind of bad, I just a

Do you really think there will be zero disasters in Arizona in the coming years? Sure the plant may survive a water crisis, how about it's power grid? How about the local communities and states who will run out of water? Over the next

My use for it was to have a 5 way residential VPN across multiple Countries for obvious reasons. That wouldn't really suffice with just ssh. It also makes the shared infrastructure a lot easier to use for the rest of my family. Also a

I have 5 locations running effectively independent VPNs, each hub connected to each other for redundancy if a VPN falls over. i.e. Each hub has 1 VPN in, or is connecting 4 ways out. If the port forwarding or something fails inbound, then I

I think there are better approaches than this. 1) Setup a VPN via wireguard and only expose that random udp port. That way only a single UDP port is exposed and port-scans become infeasible. 2) Setup 2fa via libpam-google

True, and the Linux kernel has zero-copy AF_XDP that enable memory to be shared with userspace. However, low-latency networking is a lot more than just simple kernel bypass. It's things like pinning cpu cores dedicated for networking,

by kd913 5y ago
I don't think it would be worthwhile. If you want better latency and throughput, you wouldn't be using the kernel network stack and instead be opting for some userspace networking stack like DPDK or onload. Depends obviously on wh

It's on every system that has systemd which is basically on every commercial production Linux system. I can use them as a user and non-root, I get to use journalctl and systemd status to check if it ran. The timers run independently of

How about the x2 or Alveo series from Xilinx? It is basically the original definer of smartnic. It comes from solarflare who have a long pedigree of low-latency smartnics. They used to supply Cloudflare, and also supply like 50% of fintechs

That seems rather ambiguous and doesn't really explain why having more time precision results in faster performance or 'advanced infrastructure management'. I can understand why a stock broker or trading firm requires PTP to

Does it really spin up a big core? AFAIK different C-states dictate that per-core and different caches power on. Given that, surely this can be extended further with ALUs, FPUs etc only being powered on as necessary? I assume that is alread

Is this agnostic to hardware? I thought Intel/AMD had different strategies regarding variants of spectre with AMD having specific solutions of retpoline. Without knowing the hardware, what is the point of the performance comparison?

Data can be stored, transparent but open for legitimate purposes. I don't think it's a good idea to go to the other extreme for complete anonymity in a case like this whether the consequences result in massive criminal activities.

I disagree, the computational expensive aspect is the fact that you are trying to find the inverse of the double hash. Hence you are forced to brute force. If the problem was adjusted where it wasn't using a double hash, and had some s

>Hashing is the easy part and because it is not reversible miners waste energy looping and trying different nonces so you get a hash with the required amount of zeros. The above is massively computationally expensive, hence why it's
