This is not how such storage systems work. If the whole storage system is for you and you only store compressed video files on it then perhaps. But we are talking about multi-tenant systems here. You will get better performance and/or

Having a big CPU (which you need to get many PCIe lanes) and then not using it is waste. It would be waste to _not_ use the CPU time. Granted, the CPU powet consumption would drop with enabled power management, but that's only margina

I think it is a clear cut, mostly because I do not think that compression compromises any of those features, all while making the user experience better. For any storage system like this you usually have a few bottlenecks. IO and Network ar

And the other comment made me google noise vs. pressure.... Looks like Siemens did an investigation and tested various parameters (pressure, noise, vibration) independently. They point towards noise, not pressure. Really interesting as I am

I was once told by a datacenter operator that this is due to the pressure change when they pump the gas in and that we should plan on replacing all HDDs should the fire alarm go off. ...and I think it was Argon...

Well, I was a huge fan of ceramic ones but found that they also wear off. Still better than non-stick pans, but not perfect. Might be that newer ones are better but I already switched to cast iron by now. Right now my main pan is from a Ki

At some point I got hooked to kde konsole because it allows you to hide everything: hide the scroll bar, hide the menu, hide the tabs. Nothing but window decoration & a terminal. Oh and my terminal window is slightly transparent. There

To clarify... This is at least partially the aftermath of a lawsuite if I recall correctly. There was a case where a doctor listed abortions as one of their offerings on their website, and that was seen as an advertisement. [Citation needed

Terraform and OctoDNS can make this easy. Never let the UI of your vendor be the source of truth for your DNS setup. If you have the zones in code then updates should be easy to distribute to multiple vendors. Also: given the nature of DNS

> Maybe the extra responsiveness under heavy loads is slowing it down? Yes! Extra responsiveness is done by switching more often between tasks. This is not free, so throughput suffers. The linux kernel lists that as the downside of e.g.

And it's all about tail latency for processes. A big latency spike in latency and your desktop seems to hang, the audio shutters or you see framerate drop (or even freezes) in games. How do you go after these? You optimize for fairness

Well, been down the Prometheus/Alertmanager path and it is pretty workable there. You would get all the templating and grouping by labels. Dashboards can showed Prometheus alerts through annotations on the graphs. So you get a visual f

It is probably a stretch, but I think less of a stretch than saying "it just a machine that learned to code and randomly reproduced these 10+ lines of code". That has IMHO a probability of 0. So if I rule that out, where does it e

Well, I have a hard time drawing a line between GitHub Copilot and a compression algorithm. If you can reproduce a verbatim copy of Quake source code after taking that source code as input before then that's compression. A really fancy

The former approach was release + upgrade all projects. Now if one of those fails post-update you have to build a new release and upgrade all projects _again_. Multiply that by hundreds of services and it can become pretty annoying. By pull

to clarify: the biggest concern for these devices is that the prove of ownership is leaking. And an easy way would be to copy the device. Anything that copies the identity (private key) to a physical key is broken because the identity could
