I wish lemmy communties existed for:
Edit: yeah, I think I miss a few of the old subreddit's. Even if there is an equivalent in lemmy, such communities are quite silent.
"The kernel runs out of time to solve the NP-complete scheduling problem in time."
More responsiveness requires more context-switching, which then subtracts from the available total CPU bandwidth. There is a point where the task scheduler and CPUs get so overloaded that a non-RT kernel can no longer guarantee timed events.
So, web browsing is basically poison for the task scheduler under high load. Unless you reserve some CPU bandwidth (with cgroups, etc.) beforehand for the foreground task.
Since SMT threads also aren't real cores (about ~0.4 - 0.7 of an actual core), putting 16 tasks on a 16/8 machine is only going to slow down the execution of all other tasks on the shared cores. I usually leave one CPU thread for "housekeeping" if I need to do something else. If I don't, some random task is going to be very pleased by not having to share a core. That "spare" CPU thread will be running literally everything else, so it may get saturated by the kernel tasks alone.
nice +5 is more of a suggestion to "please run this task with a worse latency on a contended CPU.".
(I think I should benchmark make -j15 vs. make -j16 to see what the difference is)
Mint was the distro that converted me. After 8-10 years, I'm still using the cinnamon DE, but just on top of Arch. Next hope is the devs port it over wayland so I can also ditch xorg. (There is a demo/alpha available)
I'm actually bit sad that I had to move onto a ISP which has zero IPv6 support, as I previously did have IPv6. The last thing I did on that connection was to debug the hell out of my IPv6 code I had developed.
If any one would hear that in my country it would be the fiasco of the century. (we have had one) You aren't even allowed to go near the studying line if you have any criminal record. When the police make an mistake in my country, there will be an investigation. And the investigation is done by a party not in the normie police force, which can and does lead to convictions of the members police force.
Instead, Americans: here is your gun, go shoot and kill anything that moves, you are unimpeachable.
I think (in general) any one should be just allowed to say "oops" in any situation, in any case, however bad it is, to note he/she/(add any extra pronouns) has said/done and gone something that should not have happened or taken place. It's like software crashing of thinking, which happens and will happen more than we would like to.
I have been using uBlock Origin and uMatrix together for so long, that I don't remember when they became permanent must have.. uBlock origin sanitizes the site, while uMatrix prevents any surprises since I last visited a site. The more garbage the site is, the more broken it is on my setup.
He fixed the standard model of particle physics. He was also the reason why this was built to prove his theory.
Fusion triple product: the duration the thing works x inverse of how close you are to melting the reactor vessel x how large is the reactor vessel
The in-rush of endorphins when the modded LCD thing actually worked probably knocked you out?
A bit of a side story: I disassemble probably 1–5 panels in a week. (For recycling, it takes about 20-45min per panel.) The flat cables alone are so flimsy, I would say just assembling a display again from known, matched and functional parts would take days. I would triple or quadruple that to assemble a display from random parts. Considering this, that modded panel is quite amazing to me.
In standalone panels, the PSU has a chance of killing you: the main capacitors can hold multiple joules worth of nope, charged to about 400v. So, if the main caps are not allowed to discharge (if they discharge at all that is), there is a possibility of death when disassembling a panel with an integrated PSU. Waiting "5min" is bad; a PSU needs to be unplugged for a day or two at least before the charge drains out.
The attack is spread via iMessage. A vulnerable device merely needs to receive a bad message with PDF attachment. --> A Remote code execution. No user interaction.
Yikes. Indeed.
The attack entry point is via bad TrueType font + PDF attachment that only needs to processed once. Once a process touches that, the attack vector begins and exploits are chained until they get kernel mode access. After getting kernel mode access all hope is lost, the attacker owns the device.
Only sliver of hope is that fixing the attack entry point blocks the current attack. And that bug is:
This attachment exploits the remote code execution vulnerability CVE-2023-41990 in the undocumented, Apple-only ADJUST TrueType font instruction. This instruction had existed since the early nineties before a patch removed it.
But unless all the CVEs are patched, it is just matter of time a new attack entry point is found.
A dum question: if both candidates are unable to function, then what happens? (Trump for his crimes, Biden for getting dementia...)
Meanwhile in Finland: the Finnish version of "build the wall":
The bill needs 5/6 parliamentary approval and politicians are already sweating over it because it touches too many international treaties + constitution. Debate is mostly: is it ready yet? is it ready yet? is it ready yet? (While the committees checking the bill are getting more uneasy by the bill's content...)
Oops, fixed.
