TIL that when top isn't granular enough for CPU profiling,
perf record -g -p <PID> -- sleep 10 && perf report
will generate call graphs to show exactly where CPU cycles are spent. Very handy.

Does #FreeBSD #kernel support #livepatching yet? I see some discussions here and there on the Internet. But I cannot find out if after all these discussions, the feature has been added or not.

@WinFuture wer Dritthersteller-#Kernelhacks bezahlt bzw. nicht den eingebauten.Mechanismen vertraut sollte das Betriebssystem.wechseln!
@Kensan @marcel @adfichter Das kommt hinzu...
Ich persönlich bin ja dafür dass #CCSS eine strikte #Produkthaftung befolgen müssen - inklusive #Versicherung für #Folgeschäden und Schadensersatzansprüche...
Ohnehin gehört #Govware wie #Windows und #Scareware wie #CrowdStrike und der ganze andere "#Antivirus" - #Malware verboten, weil alles was #Binaryblob-#Kernelhacks erzeugen ist Mist!
@0xabad1dea which confirms my own point.
All #KernelLevelDrivers are #malware and should not exist to begin with.
There was never a #LegitimateReason to allow said #Kernelhacks to exist.
Noone should've allowed this #scareware to exist or signed it (#Microsoft) nor used it and the #Govware it was made for (#Windows).
I sincerely hope they'll be made to face #accountability and #consequences for this shitshow, and I mean not a #ClassAction aka. "#GetOutOfJailCheque" that is insultingly low.
@Cappyjax @WB2EEE @Zugschlus @elly
I disagree with your assessment to some extent, as on #Linux there's not much of a tolerace or even acceptance of #rootkits like #CorwdStrike for all the right reasons!
Cuz it's not about #Fanboyism, but a fact that most Windows - #Sysadmins (or rather decisionmakers for that matter) seem to be high on #Copium and refuse to take actual #consequences but accept the #Enshittification as a fact of life when it's not...
It's just that this entire shitshow would not have happened on #Linux because here we don't have an entire ecosystem of #ValueRemoving "#AntiVirus" bs being shoved on Desktops and Servers in the form of #Binaryblob #Kernelhacks!
@nbloglinks @jos1264 @bsi generally you can't trust any #DigitalSnakeoil delers aka. 3rd Party #Antivirus for #Windows and #macOS!
As both OSes are proprietary, said "Antivirus" are ugly #BinaryBlob #Kernelhacks!
If you don't trust #Microsoft and #Apple.respectably to maintain their OSes and keep them secure, then DON'T USE SAID OS!
@Szwendacz I think #Antivirus and #Malware protection should be the sole responsibility of the #maintainer of said #OS / #Distro!
And I'd happily pay for #support and have that in writing for more than just #compliance reasons...
That being said #Linux already dominates (#Android is just a #toybox + #musl / #Linux distro and for the vast majority of people - espechally in the global south, it is their #Desktop!) and it "solved" the malware problem just by taking away 'the means to fuck up a system' from #TechIlliterate #users - as any reasonable #sysadmin should do anyway...
So yeah, 3rd party #AV may seem like #Scareware on #Linux (and #Mailservers should at least #ClamAV their inboxes) but on Windows they are absolutely pointless given than those are #BinaryBlob - #Kernelhacks (none of them got Sourcecode access for Windows!) that actually lessen #security of the System!
