I ended up here by working in tech to pay off my student loans. Mostly sysadmin and infosec info on this account. I think I need multiple accounts for all the content I want to explore.

Trying to keep SN ratio high w/o becoming a reply guy. Or maybe this is like my Sent Mail folder so I remember things...

I hate unpredictable automation.

@ai6yr@m.ai6yr.org I still used a manual typewriter in the early 21st century to fill in multi-layer shipping manifests (the ones with the embedded carbon paper). Mashing the keys required so you could read your copy. :-) and as other have said, *ding* is required.

@W6KME@mastodon.radio @ai6yr@mastodon.radio Not just funk, he needs 80s help, IMHO. Blondie, Specials, Clash - London Calling, X (the Band). Since you're starting with Kraftwerk you need some Deep Forest from the 90s. and Rick Rubin/Johnny Cash is a must for the late grunge era.

@nygren@hachyderm.io I always say TLS when I mean TLS 1.2 or higher. If a vendor or customer is using SSL loosely I ask if they mean TLS 1.2 or 1.3. It sets a technical baseline and still allows for talking about older historical usage or when looking for insecure certificates on a network.

@sundogplanets@mastodon.social You can always ask what time is that in Zulu? to make them think you work for the military or some other agency or confuse the less informed ones. Make them do at least some work.

@douglasvb@m.ai6yr.org Since datacenters now need to be protected from drones why not repurpose a Nimitz -class carrier for nuclear powered datacenters? The flight deck can be used for anti-drone flights, keep the AA guns, water cooling, ship-to-shore power if needed. Some of the tech is already being evaluated, https://www.stripes.com/branches/navy/2026-01-02/nimitz-nuclear-reactor-data-center-20259929.html

USS Nimitz reactors could power future land-based AI data center

If the Nimitz project succeeds, reactors from future decommissioned aircraft carriers, submarines and other sources could be used for data centers.

@nicksilkey@hachyderm.io There's a make everything fit in one response packet recommendation to avoid fragmentation. This doc says 1400 for max payload size. There's no quick rule-of-thumb these days since IPv6 and DNSSEC are variable, see section 5 for recommendations. https://www.ietf.org/archive/id/draft-ietf-dnsop-avoid-fragmentation-07.html

@irene I went to a college-prep school in Monterey that still has the students perform minor maintenance tasks on campus. (It's a very small school.) One of the tasks is collecting invasive iceplants.

Hat Tip to The Register, “Lumai detailed its optical inference accelerator, which uses light, rather than electrons, to perform the matrix multiplication operations at the heart of most machine learning workloads using a fraction of the power of a purely digital architecture.” https://www.theregister.com/2026/05/03/inference_is_giving_ai_chip/

Re-reading my post, I see there's a huge gap in logic. I'm assuming everybody knows that all printed books are part of LLM the dataset. Why am I explaining my own post? To make up for this, here's a link the RISKS digest post mentioned in the article with the quote from the author of _Disinfectant (68k Mac AV software). https://catless.ncl.ac.uk/Risks/16.55.html#subj3

A hardware bug still showing up over 30 years later. I wonder if more bugs like these are being used as generativeAI detectors. Will it affect more people than the number of faulty keyboards sold? #classicmac #gigo #generativeAI #genAI https://sixcolors.com/link/2026/06/welcome-datacomp/

This isn't a bad overview of AI risk from a re-insurer (the insurance co for insurance companies). Different AI use cases with real-world examples and case studies. Use this to educate non-technical/non-risk specialist staff. Also has a glossary.

Oh dear, I may have to watch this series for its BCP and IR content, of course. #bcp #businesscontinuity #incidentresponse ""Waffle House Index" follows a Waffle House waitress as a series of mounting disasters unfold during her night shift. First, a man with a gun, then a flood, followed by killer crocodiles, nuclear explosions, and yes: even aliens." https://appleinsider.com/articles/26/09/03/apple-tv-picks-up-sci-fi-thriller-waffle-house-index-in-seven-figure-deal

Apple lands disaster film 'Waffle House Index'

Apple TV is betting on the Waffle House Index for a sci-fi disaster flick that takes the restaurant's reputation for staying open to its logical extreme.
