Not for me. I see the expected news article.

This is not a US electrical outlet, but it's one I've recently become aware of, which folks might find interesting:
Our next data center, for the HPC portion, may end up getting 480 VAC to the rack, with each outlet getting 277 VAC (one phase plus neutral and ground). If you order a generic Dell server, you'll find they now have power supply options for 277VAC.
What's the outlet? The D-Grid 400 (SDG 400). So, there's another outlet to add to the list!

> But my understanding is the US 110v thing is kinda limiting, and 220v is way better.
120V is safer (not "safe", "safer"[1]) than 240V. And for the times when 240V (or 208V) is a better fit, we have that available to us relatively easily.
> For what? The only bulky US plugs are for weird things like dryers and electric ovens.
Or the locking plugs, but I think that still fits your point: These are high-voltage and/or high-current things, which aren't being unplugged/plugged too much.

A long time ago, I'd participate in things like CAcert in-person assurance, PGP key-signing, etc.. I think a model like that would've been useful here: An AgeKey issued/signed by two people. I think of it like a decentralized equivalent to someone's parents saying "Yeah, $CHILD is old enough", or to a cashier saying "This person obviously looks old".

A friend of mine, who lives in the UK, says that he's been offered the credit-card verification option.

I forget, doesn't Audacity also have you do this, if you want to be able to export projects as MP3?

The best way to ask for this is to send an email, to the email address which you can find at the bottom of the page (click on "Contact"). There's no guarantee that the mods will find your comment otherwise.

What was the failure rate of those vacuum tubes, that they had to be so quick & easy to replace?
I'm also curious, if the cathode was grounded to the machine frame, how dangerous was it to do work on those machines?

Stanford Research Computing | Stanford, CA (next to Palo Alto) | Full-time | Four positions | HYBRID,ONSITE
Stanford Research Computing (https://srcc.stanford.edu) is a collaboration between University IT and the Vice Provost and Dean of Research. We operate HPC environments for researchers, we do one-time consultations on projects (from software and pipelines, to data management, to physical building design and fit-out), and we provide contract support for individual Labs, Departments, and Schools.
We have four open positions, three hybrid and one (marked) onsite:
• Principal Storage Architect & Team Lead: Our current storage team lead is moving on to Industry, so we're splitting his work into two separate roles. This is the Technical Manager position: You'll be leading the storage team, setting the direction for our large storage environments: Oak (file storage, used by multiple cluster), Fir (fast scratch for Sherlock), and Elm (object storage on top of tape). Knowledge of Lustre, Infiniband, and PB-scale storage is important. More info: https://bit.ly/44PbQnr
• Storage Architect or Storage Sysadmin: This is the second role I referenced above. You'll be maintaining & expanding Oak, our 20+ Pebibyte Lustre storage environment used by our largest HPC clusters. Depending on your experience level, you might also have some responsibility for Elm, which provides object storage on top of tape. Knowledge of Lustre, Infiniband, and PB-scale storage is important here, too. More info: https://bit.ly/4y8lj6R
• GPU System Engineer: We are looking to hire a lead sysadmin for Marlowe—our 1SU NVIDIA DGX H100 SuperPOD with DDN Intelliflash and DDN NFS storage—launched. You'll be working with the latest AI/ML/Deep Learning/LLM software & frameworks, getting them to work in an HPC environment. You'll be keeping the environment up-to-date, and working with NVIDIA/DDN when there's trouble. You should also expect to interact with users & PIs a lot. More info: https://bit.ly/4vf7aly
• HPC Hardware & Infra Sysadmin [ONSITE]: We are looking for a system administrator to help run the hardware & infrastructure portions of Sherlock, our largest HPC cluster. Sherlock is a mix of Intel & AMD x86_64 servers, with three Infiniband fabrics, plus an Ethernet backbone. You'll be responsible for maintaining, troubleshooting, and improving the hardware of Sherlock. That is, keeping things working, and figuring out how to make it better. More info: https://bit.ly/3SPRpnJ
If you don't already live in the Bay Area, we provide a relocation incentive. Depending on where you live, we provide free transit passes. Unfortunately, if you drive, you will have to pay for parking for the days you're on-site. There is some on-call around the holidays. We get a 403(b) match, good healthcare, and 30+ days off per year (holidays + vacation). All Benefits are all publicly documented at https://cardinalatwork.stanford.edu/benefits-rewards.
If you have questions, feel free to reply here or email me (the info is in my profile)!
