System Administration: Week 13: Ethics and Social Responsibility (now with AI, oh boy!)

In this week's lecture, we discuss the professional codes of ethics in our field, some hairy ethical dilemmas encountered by #SysAdmins and other engineers, and how we can take an active role in acting in the public interest as part of our jobs.

There are a number of unsurprising parallels to a conference talk I gave way back at Velocity in 2015:

🎩💻 Behold the hacker's wet dream: bypassing noexec like it's 1999, because who needs #security when you have a #PoC that screams "I told you so" at sysadmins? 🙄 Spoiler alert: defense in depth is just a bedtime story for the gullible. 😴🔍

Ok, I'll try it here and see if someone can help me.
I'm preparing a #Windows11 machine, installed all the software but when is #sysprep time, it fails:
Audit mode cannot be turned on if reserved storage is in use. An update or servicing operation may be using reserved storage.; hr = 0x800F0975

#DISM/Get-ReservedStorageState -> Disabled (done through regedit)
Updates? done, and paused

Tried everything I've found (replacing #spopk, redoing the machine)

Any ideas? #fedihelp #sysadmins #helpdesk

--> SOLVED <--

Hi Mastodon-Admins,

I'm the admin of an instance running on v4.3.21 and would like to upgrade to v4.5.0. In the 4.5.0 release notes I can see the update steps for v4.4.8.

Is there any chance I can update directly from v4.3.21 to v4.4.8 or do I have to sequentially update through all the minor releases v4.4.0-v4.4.8?

It’s Friday evening. The production server isn’t responding. VPN drops every two minutes. Three hours later, you’re still fighting configs. Thousands of developers & #sysadmins face this.

@netbird, an #opensource networking platform, can help!

Dive into this article by Daniele Briguglio to see how: https://lpi.org/bdp3

Java TLS has been a blind spot for eBPF-based #observability tools for years. JSSE runs entirely inside the JVM with no exported symbols and nothing to attach to.

Here is how to solve it: https://coroot.com/blog/java-tls-instrumentation-with-ebpf/

Benchmarking our eBPF Java TLS agent against OpenTelemetry, Coroot added only +15% CPU overhead vs +38% from OTEL, which dropped 20% of requests under load.

Le #fédivers sert essentiellement à suivre des #geeks #sysadmins de gauche, des universitaires dépité.e.s et des brodeuses manuelles.

On l'a bien compris.

Les musicien.ne.s #antiGAFAM pas #geek ni dev, on les renvoie sur fcbook Einztagram, au même titre que les sales macronistes ?
