For the same reason spoken languages often have semantic structures that make a literal translation often cumbersome and incorrect, translating nontrivial code from one language into another without being a near expert in both langauges, as well as being an expert in the project in question, can lead to differences in behaviour varying from “it crashes and takes down the OS with it”, to “it performs worse”.
A rather overly simplistic view of filesystem design.
More complex data structures are harder to optimise for pretty much all operations, but I’d suggest the overwhelmingly most important metric for performance is development time.
Yes, but note that neither the Linux foundation nor OpenZFS are going to put themselves in legal risk on the word of a stack exchange comment, no matter who it’s from. Even if their legal teams all have no issue, Oracle has a reputation for being litigious and the fact that they haven’t resolved the issue once and for all despite the fact they could suggest they’re keeping the possibility of litigation in their back pocket (regardless of if such a case would have merit).
Canonical has said they don’t think there is an issue and put their money where their mouth was, but they are one of very few to do so.
Opengear in Brisbane; development teams often use Linux.
Brand new anything will not show up with amazing performance, because the primary focus is correctness and features secondary.
Premature optimisation could kill a project’s maintainability; wait a few years. Even then, despite Ken’s optimism I’m not certain we’ll see performance beating a good non-cow filesystem; XFS and EXT4 have been eeking out performance for many years.
License incompatibility is one big reason OpenZFS is not in-tree for Linux, there is plenty of public discussion about this online.
I’ll also tac on that when you use cloud storage, what do you think your stuff is stored on at the end of the day? Sure as shit not Bcachefs yet, but it’s more likely than not on some netapp appliance for the same features that Bcachefs is developing.
In addition to the comment on the mentioned better hardware flexibility, I’ve seen really interesting features like defining compression & deduplication in a granular way, even to the point of having a compression algo when you first write data, and then a different more expensive one when your computer is idle.
This is actually a feature that enterprise SAN solutions have had for a while, being able choose your level of redundancy & performance at a file level is extremely useful for minimising downtime and not replicating ephemeral data.
Most filesystem features are not for the average user who has their data replicated in a cloud service; they’re for businesses where this flexibility saves a lot of money.
Regarding 1: if you open up dmesg after it happens and you see an error regarding “No edid read”, your GPU is having a hard time automatically getting the monitor’s edid over display port. My 7800xt has this issue.
If your monitor setup doesn’t change much, you can manually set the edid on a per output basis. Here is a good guide.
Also, regarding 3: you may need to set your amdgpu feature mask in your kernel parameters.
Care to elaborate?
I’ve seen some optometry equipment running RHEL
About a year ago I moved to Hyprland & Wayfire for my NVIDIA & Intel boxes. Moved NVIDIA to Radeon a few months back and had mixed results.
Recently tried Plasma 6 for experimental HDR and am impressed.

Most firewalls are at their safest when you first get them i.e by default they block everything coming in. As you start doing port forwarding and the like you start making the network selectively less secure; that’s when you have to pay attention.
I had an EdgeRouter X for years before I started my job. They are solid devices, and I’d definitely put them above most consumer routers.
Because they only charge for the hardware, they will eventually run into the same disincentive to provide consistent timely updates. If you do buy an Ubiquiti or similar enthusiast brand, do still keep an eye out for the CVEs that don’t get patched.
I build Linux routers for my day job. Some advice:
your firewall should be an appliance first and foremost; you apply appropriate settings and then other than periodic updates, you should leave it TF alone. If your firewall is on a machine that you regularly modify, you will one day change your firewall settings unknowingly. Put all your other devices behind said firewall appliance. A physical device is best, since correctly forwarding everything to your firewall comes under the “will one day unknowingly modify” category.
use open source firewall & routing software such as OpenWRT and PFSense. Any commercial router that keeps up to date and patches security vulnerabilities, you cannot afford.
It opens the door to more manufacturers since there is no ISA licence fees. While the AMD/Intel duopoly is being fairly competitive at the moment, it really doesn’t have to be. Only think back to how bad it was late 2000s to 2015.
I imagine a plethora of core designers, soc vendors and platform creators filling their own niches; lowest cost, lowest power, HW accelerators, highest core count etc.
I don’t see the raw performance of AMD/Intel being surpassed soon, just because of the sheer total R&D years each has, but that doesn’t mean there aren’t other areas better suited to a different architectural approach.
I don’t see the problem, I also don’t see how this is a novel situation.
The technical merits of system level protocols only really affect the user insofar as they make it easier for userspace application writers to make their software. This is why we have the distinction, so that users never have to change the underlying software, and when they choose to it’s because everything just works.
They’re not trivializing, just noting that the different things you need to discuss for kernel development compared with other work. It is very different in a lot of ways, and does shape your perspective. I also find it interesting.
