Not the first time I've said this: the 1970s-era GEC OS4000[1] was really fast, like compared with everyone's VAX 780s, and we users benefited in the '80s. I don't know whether or …

The latest page cache-related LPE, even though it's not Thursday night (here). EL9 kernels don't have the modules enabled, and the PoC doesn't build on Debian 13 or Ubuntu 24.04, w…

You might not have root on an organizational "managed" system.

Any university or national HPC system as I'd understand the term is multi-user. There are also things like the extensive high energy physics WLCG compute federation, which is somew…

The primary source, which says keep the dirtyfrag mitigations in place, is https://github.com/v12-security/pocs/tree/main/fragnesia

Yes, but its authN components only act locally, and PAM is optional for sshd. It can/does call out to network services like Kerberos/LDAP given a password, of course, but I was thi…

I'm happy for anyone who doesn't have MS Windows/Active Directory -- so Kerberos -- in their organization, but I'd need (Free)IPA or similar for user/access management anyway. Cert…

Yes, FreeIPA is Kerberos+LDAP+X.509 CA, and GSSAPI is in OpenSSH (normally with the key exchange patch). SSSD is a local mechanism, not network authentication. I mentioned authoriz…

I don't want to have to get a special purpose credential when I have a TGT which can work generally, and is at least required for secure remote filesystem access. You have to manag…

Public keys (for OpenSSH) can be in DNS (VerifyHostKeyDNS) or in, say, LDAP via KnownHostsCommand and AuthorizedKeysCommand.

If you mean using OIDC, in that space there's at least https://github.com/EOSC-synergy/ssh-oidc , https://dianagudu.github.io/mccli/ and OpenPubkey-ssh discussed in https://news.yc…

Life is easier if you can use Kerberos SSO, i.e. GSSAPIAuthentication in OpenSSH. (If we're talking certificates, presumably it is OpenSSH, or does anything else implement them?)

As far as I remember, that's just because only the find/replace was implemented, and it could have more sophisticated (semantic?) features.

Its author says it implements a CRDT in its theory documentation.

Before isnan() the Fortran test for NaN was (x .ne. x), assuming an IEEE 754 implementation.

> I had a Fairphone 3, and after 5 years, /e/OS was outdated by 4 years w.r.t. the manufacturer updates Mine is running /e/ and reporting Android 13, which appears to be the last o…

Some of those codebases might be (interesting) operating systems. https://en.wikipedia.org/wiki/ALGOL_68#Operating_systems_wri...

Used in the impressive Guix bootstrap. https://guix.gnu.org/manual/1.5.0/en/html_node/Full_002dSour...

Indeed. The first dedicated light -- for various values of "light" -- source[1] repurposed the tunnel and various bits and techniques from the particle physics accelerator it repla…

In the context of the article "collider" means intersecting particle beams, like in RHIC and LHC, which obviously involves rather low probability interactions, as opposed to accele…

You imply that experiment contaminated drinking, and other, water. How? Are you saying the Cs¹³⁷ leaked, and at concentration above that from fallout, say? Its γ-rays don't activat…

Since when were industrial products the purpose? Why do you think my colleagues can't analyse LHC data and discover the Higgs particle? The article says RHIC was a considerable sci…

As I recall, RHIC itself replaced some cancelled project. I remember the tunnel being at least partly there in the mid-80s, with a plan to trundle ions from the tandem lab through …
