N100/N150 doesn't really have enough PCIe lanes to be considered good fit for a NAS.

The PHY contributes only 1ns difference, but the results also show 400ps/m advantage for copper which I can only assume to come from difference in EM propagation speed in the medium.

What are applications where 5ns latency improvement is significant?

Video streaming usually uses something like DASH/HLS and is fair bit more complicated than Range headers. Notably this means that downloading the video means reversing the streaming format and glueing the segments together.

The article is conveniently ignoring that getting your own IP block ranges from practically impossible (ipv4) to very involved (ipv6). And then you also need to figure out way to route traffic for that IP block; not all ISPs and hosting pro

The table in Wikipedia is good for clarifying matters: https://en.wikipedia.org/wiki/Unix_time#Leap_seconds From there you can clearly see that e.g. Unix time 915148800 lasted two seconds We can make an analogy to leap

> And the "second" in this definition means what people usually understand as a second, as in the duration is always the same. Umm what? In Unix time some values span two seconds, which is the crux of the problem. In UTC every

It is why we are introducing LTC, Coordinated Lunar Time. Apparently the relativistic effects on the Moon are already big enough to make using UTC problematic.

ISO 8601, one of the most common date notations, does have year zero. It really depends on what specific calendar you use. Gregorian calendar itself only starts at 1582, anything before that is some sort of extension.

DPI (or PPI) is an absolute measurement. Scale factor is intentionally relative. Different circumstances will want to have different scale factor : dpi ratios; most software do not care if certain UI element is exactly x mm in size, but ins

It is a pet peeve of mine, but any statement that implies that Unix time is a count of seconds since epoch is annoyingly misleading and perpetuates such misconception. Imho better mental model for Unix time is that has two parts, days since

Hundreds of Gbps of UDP traffic to random ports of a single destination IP from residental (?) network should be pretty easy pattern to automatically detect and throttle. More advanced attacks are more tricky to detect, but plain dumb UDP f

GPL guarantees you rights to make the old drivers available forever. Of course it is the nature of FOSS that ultimately you are responsible for your own systems and their maintenance.

IP fragmentation does not really have anything to do with UDP, it can happen regardless of the inner protocol. > Worst of all, this was all avoidable. It is not that simple. To avoid fragmentation you need robust path mtu detection, whic

Yeah, this is the way to do this. I'm pretty sure that if you for some reason do not want to run wireguard on all your servers you could fairly easily adjust this recipe to have a centralized wg gateway on your local network instead. I

NIST has operated public random beacon since at least 2013, and League of Entropy has operated distributed beacon from 2019. Public randomness does have uses in cryptography, crypto is not only secret keys.

I would have thought that the frequencies (or their ratios) of atomic clocks could be calculated somehow from the fundamental physics. Like somehow the energy levels of electron shells could be determined from the configuration of the nucle

Google Maps gives LA-SF straight line distance as 347 miles and driving instructions (via I-5) as 381 miles.

LA-SF distance is roughly 560km, that feels relatively short for overnight train? Like it's comparable to Madrid-Barcelona (500ish km) which is 2h37min by train, or Paris-Bordeaux at 2h11min; I doubt anyone is considering sleepers for
